From: Thomas Bertschinger tahbertschinger@gmail.com
[ Upstream commit 1b6170ff7a203a5e8354f19b7839fe8b897a9c0d ]
Currently Rust kernel modules have their init code placed in the `.text` section of the .ko file. I don't think this causes any real problems for Rust modules as long as all code called during initialization lives in `.text`.
However, if a Rust `init_module()` function (that lives in `.text`) calls a function marked with `__init` (in C) or `#[link_section = ".init.text"]` (in Rust), then a warning is generated by modpost because that function lives in `.init.text`. For example:
WARNING: modpost: fs/bcachefs/bcachefs: section mismatch in reference: init_module+0x6 (section: .text) -> _RNvXCsj7d3tFpT5JS_15bcachefs_moduleNtB2_8BcachefsNtCsjDtqRIL3JAG_6kernel6Module4init (section: .init.text)
I ran into this while experimenting with converting the bcachefs kernel module from C to Rust. The module's `init()`, written in Rust, calls C functions like `bch2_vfs_init()` which are placed in `.init.text`.
This patch places the macro-generated `init_module()` Rust function in the `.init.text` section. It also marks `init_module()` as unsafe--now it may not be called after module initialization completes because it may be freed already.
Note that this is not enough on its own to actually get all the module initialization code in that section. The module author must still add the `#[link_section = ".init.text"]` attribute to the Rust `init()` in the `impl kernel::Module` block in order to then call `__init` functions. However, this patch enables module authors do so, when previously it would not be possible (without warnings).

[ Upstream commit 7044dcff8301b29269016ebd17df27c4736140d2 ]
The `module!` macro creates glue code that are called by C to initialize the Rust modules using the `Module::init` function. Part of this glue code are the local functions `__init` and `__exit` that are used to initialize/destroy the Rust module.
These functions are safe and also visible to the Rust mod in which the `module!` macro is invoked. This means that they can be called by other safe Rust code. But since they contain `unsafe` blocks that rely on only being called at the right time, this is a soundness issue.
Wrap these generated functions inside of two private modules, this guarantees that the public functions cannot be called from the outside. Make the safe functions `unsafe` and add SAFETY comments.

The "pctldev" struct is allocated in devm_pinctrl_register_and_init(). It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(), so freeing it in pinctrl_enable() will lead to a double free.
The devm_pinctrl_dev_release() function frees the pindescs and destroys the mutex as well.

In the generic pin config library, readback of some options are handled differently compared to the setting of those options: the argument value is used to convey enable/disable of an option in the set path, but success or -EINVAL is used to convey if an option is enabled or disabled in the debugfs readback path.
PIN_CONFIG_INPUT_SCHMITT_ENABLE is one such option. Fix the readback of the option in the mediatek-paris library, so that the debugfs dump is not showing "input schmitt enabled" for pins that don't have it enabled.

[ Upstream commit c5d3b64c568a344e998830e0e94a7c04e372f89b ]
There is a misinterpretation of some of the PIN_CONFIG_* options in this driver library. PIN_CONFIG_OUTPUT_ENABLE should refer to a buffer or switch in the output direction of the electrical path. The MediaTek hardware does not have such a thing. The driver incorrectly maps this option to the GPIO function's direction.
Likewise, PIN_CONFIG_INPUT_ENABLE should refer to a buffer or switch in the input direction. The hardware does have such a mechanism, and is mapped to the IES bit. The driver however sets the direction in addition to the IES bit, which is incorrect. On readback, the IES bit isn't even considered.
Ironically, the driver does not support readback for PIN_CONFIG_OUTPUT, while its readback of PIN_CONFIG_{INPUT,OUTPUT}_ENABLE is what it should be doing for PIN_CONFIG_OUTPUT.
Rework support for these three options, so that PIN_CONFIG_OUTPUT_ENABLE is completely removed, PIN_CONFIG_INPUT_ENABLE is only linked to the IES bit, and PIN_CONFIG_OUTPUT is linked to the GPIO function's direction and output level.

We're using nfs mounts inside of containers in production and noticed that the nfs stats are not exposed in /proc. This is a problem for us as we use these stats for monitoring, and have to do this awkward bind mount from the main host into the container in order to get to these states.
Add the rpc_proc_register call to the pernet operations entry and exit points so these stats can be exposed inside of network namespaces.

[ Upstream commit 24457f1be29f1e7042e50a7749f5c2dde8c433c8 ]
syzkaller reported a warning [0] triggered while destroying immature netns.
rpc_proc_register() was called in init_nfs_fs(), but its error has been ignored since at least the initial commit 1da177e4c3f4 ("Linux-2.6.12-rc2").
Recently, commit d47151b79e32 ("nfs: expose /proc/net/sunrpc/nfs in net namespaces") converted the procfs to per-netns and made the problem more visible.
Even when rpc_proc_register() fails, nfs_net_init() could succeed, and thus nfs_net_exit() will be called while destroying the netns.

[ Upstream commit fed6d9a8e6a60ecf6506d0ea004040fbaa109927 ]
For all the "score" pin-groups all the intel_pingroup-s to select the non GPIO function are re-used for byt_score_gpio_groups[].
But this is incorrect since a pin-group includes the mode setting, which for the non GPIO functions generally is 1, where as to select the GPIO function mode must be set to 0.
So the GPIO function needs separate intel_pingroup-s with their own mode value of 0.
Add a new PIN_GROUP_GPIO macro which adds a foo_gpio entry to each pin-group defined this way and update byt_score_gpio_groups[] to point to the new foo_gpio entries.
The "sus" usb_oc_grp usb_ulpi_grp and pcu_spi_grp pin-groups are special because these have a non 0 mode value to select the GPIO functions and these already have matching foo_gpio pin-groups, leave these are unchanged.
The pmu_clk "sus" groups added in commit 2f46d7f7e959 ("pinctrl: baytrail: Add pinconf group + function for the pmu_clk") do need to use the new PIN_GROUP_GPIO macro.

The of_match shall correspond to the name of the regulator subnode, or the deprecated `regulator-compatible` property must be used: failing to do so, the regulator won't probe (and the driver will as well not probe).
Since the devicetree binding for this driver is actually correct and wants DTs to use the "usb-otg-vbus-regulator" subnode name, fix this driver by aligning the `of_match` string to what the DT binding wants.

[ Upstream commit 93483ac5fec62cc1de166051b219d953bb5e4ef4 ]
We are running nfsd servers inside of containers with their own network namespace, and we want to monitor these services using the stats found in /proc. However these are not exposed in the proc inside of the container, so we have to bind mount the host /proc into our containers to get at this information.
Separate out the stat counters init and the proc registration, and move the proc registration into the pernet operations entry and exit points so that these stats can be exposed inside of network namespaces.
This is an intermediate step, this just exposes the global counters in the network namespace. Subsequent patches will move these counters into the per-network namespace container.

[ Upstream commit 4b14885411f74b2b0ce0eb2b39d0fffe54e5ca0d ]
We have a global set of counters that we modify for all of the nfsd operations, but now that we're exposing these stats across all network namespaces we need to make the stats also be per-network namespace. We already have some caching stats that are per-network namespace, so move these definitions into the same counter and then adjust all the helpers and users of these stats to provide the appropriate nfsd_net struct so that the stats are maintained for the per-network namespace objects.

The MT6360 regulator binding, the example in the MT6360 mfd binding, and the devicetree users of those bindings are rightfully declaring MT6360 regulator subnodes with non-capital names, and luckily without using the deprecated regulator-compatible property.
With this driver declaring capitalized BUCKx/LDOx as of_match string for the node names, obviously no regulator gets probed: fix that by changing the MT6360_REGULATOR_DESC macro to add a "match" parameter which gets assigned to the of_match.

[ Upstream commit 96e20adc43c4f81e9163a5188cee75a6dd393e09 ]
The devm_regulator_get_enable() should be a 'call and forget' API, meaning, when it is used to enable the regulators, the API does not provide a handle to do any further control of the regulators. It gives no real benefit to return an error from the stub if CONFIG_REGULATOR is not set.
On the contrary, returning and error is causing problems to drivers when hardware is such it works out just fine with no regulator control. Returning an error forces drivers to specifically handle the case where CONFIG_REGULATOR is not set, making the mere existence of the stub questionalble. Furthermore, the stub of the regulator_enable() seems to be returning Ok.
Change the stub implementation for the devm_regulator_get_enable() to return Ok so drivers do not separately handle the case where the CONFIG_REGULATOR is not set.

The devm_regulator_get_enable_optional() should be a 'call and forget' API, meaning, when it is used to enable the regulators, the API does not provide a handle to do any further control of the regulators. It gives no real benefit to return an error from the stub if CONFIG_REGULATOR is not set.
On the contrary, returning an error is causing problems to drivers when hardware is such it works out just fine with no regulator control. Returning an error forces drivers to specifically handle the case where CONFIG_REGULATOR is not set, making the mere existence of the stub questionalble.
Change the stub implementation for the devm_regulator_get_enable_optional() to return Ok so drivers do not separately handle the case where the CONFIG_REGULATOR is not set.

Turns out that due to CONFIG_DEBUG_INFO_BTF_MODULES not having an explicitly specified "menu item name" in Kconfig, it's basically impossible to turn it off (see [0]).
This patch fixes the issue by defining menu name for CONFIG_DEBUG_INFO_BTF_MODULES, which makes it actually adjustable and independent of CONFIG_DEBUG_INFO_BTF, in the sense that one can have DEBUG_INFO_BTF=y and DEBUG_INFO_BTF_MODULES=n.
We still keep it as defaulting to Y, of course.

Prior to this, commit 4cd12c6065df ("bpf, sockmap: Fix NULL pointer dereference in sk_psock_verdict_data_ready()") fixed one NULL pointer similarly due to no protection of saved_data_ready. Here is another different caller causing the same issue because of the same reason. So we should protect it with sk_callback_lock read lock because the writer side in the sk_psock_drop() uses "write_lock_bh(&sk->sk_callback_lock);".
To avoid errors that could happen in future, I move those two pairs of lock into the sk_psock_data_ready(), which is suggested by John Fastabend.

[ Upstream commit 70ee853eec5693fefd8348a2b049d9cb83362e58 ]
Add a regmap_read_bypassed() to allow reads from the hardware registers while the regmap is in cache-only mode.
A typical use for this is to keep the cache in cache-only mode until the hardware has reached a valid state, but one or more status registers must be polled to determine when this state is reached.
For example, firmware download on the cs35l56 can take several seconds if there are multiple amps sharing limited bus bandwidth. This is too long to block in probe() so it is done as a background task. The device must be soft-reset to reboot the firmware and during this time the registers are not accessible, so the cache should be in cache-only. But the driver must poll a register to detect when reboot has completed.

Long ago a map file descriptor in a pseudo ldimm64 instruction could only be present as an immediate value insn[0].imm, and thus this value was used in a verbose verifier message printed when the file descriptor wasn't valid. Since addition of BPF_PSEUDO_MAP_IDX_VALUE/BPF_PSEUDO_MAP_IDX the insn[0].imm field can also contain an index pointing to the file descriptor in the attr.fd_array array. However, if the file descriptor is invalid, the verifier still prints the verbose message containing value of insn[0].imm. Patch the verifier message to always print the actual file descriptor value.

The version format string in the AXI SPI Engine driver was probably intended to print the version number in the same format as the DT compatible string (e.g. 1.00.a). However, the version just uses semantic versioning so formatting the patch number as a character is not correct and would result in printing control characters for patch numbers less than 32.

When __bpf_prog_enter() returns zero, the arm64 register x20 that stores prog start time is not assigned to zero, causing incorrect runtime stats.
To fix it, assign the return value of bpf_prog_enter() to x20 register immediately upon its return.

When creating controls attached to widgets, there are a lot of rules if they get their name prefixed with widget name or not. Due to that controls ended up with weirdly looking names like "ssp0_fe DSP Volume", while topology set it to "DSP Volume".
Fix this by setting no_wname_in_kcontrol_name to true in avs topology widgets which disables unwanted behaviour.

[ Upstream commit c6f48506ba30c722dd9d89aa6a40eb1926277dff ]
The current implementation of the mov instruction with sign extension has the following problems:
1. It clobbers the source register if it is not stacked because it sign extends the source and then moves it to the destination. 2. If the dst_reg is stacked, the current code doesn't write the value back in case of 64-bit mov. 3. There is room for improvement by emitting fewer instructions.
The steps for fixing this and the instructions emitted by the JIT are explained below with examples in all combinations:
Case A: offset == 32: =====================
Case A.1: src and dst are stacked registers: -------------------------------------------- 1. Load src_lo into tmp_lo 2. Store tmp_lo into dst_lo 3. Sign extend tmp_lo into tmp_hi 4. Store tmp_hi to dst_hi
Example: r3 = (s32)r3 r3 is a stacked register
ldr r6, [r11, #-16] // Load r3_lo into tmp_lo // str to dst_lo is not emitted because src_lo == dst_lo asr r7, r6, #31 // Sign extend tmp_lo into tmp_hi str r7, [r11, #-12] // Store tmp_hi into r3_hi
Case A.2: src is stacked but dst is not: ---------------------------------------- 1. Load src_lo into dst_lo 2. Sign extend dst_lo into dst_hi
Example: r6 = (s32)r3 r6 maps to {ARM_R5, ARM_R4} and r3 is stacked
ldr r4, [r11, #-16] // Load r3_lo into r6_lo asr r5, r4, #31 // Sign extend r6_lo into r6_hi
Case A.3: src is not stacked but dst is stacked: ------------------------------------------------ 1. Store src_lo into dst_lo 2. Sign extend src_lo into tmp_hi 3. Store tmp_hi to dst_hi
Example: r3 = (s32)r6 r3 is stacked and r6 maps to {ARM_R5, ARM_R4}
str r4, [r11, #-16] // Store r6_lo to r3_lo asr r7, r4, #31 // Sign extend r6_lo into tmp_hi str r7, [r11, #-12] // Store tmp_hi to dest_hi
Case A.4: Both src and dst are not stacked: ------------------------------------------- 1. Mov src_lo into dst_lo 2. Sign extend src_lo into dst_hi
Example: (bf) r6 = (s32)r6 r6 maps to {ARM_R5, ARM_R4}
// Mov not emitted because dst == src asr r5, r4, #31 // Sign extend r6_lo into r6_hi
Case B: offset != 32: =====================
Case B.1: src and dst are stacked registers: -------------------------------------------- 1. Load src_lo into tmp_lo 2. Sign extend tmp_lo according to offset. 3. Store tmp_lo into dst_lo 4. Sign extend tmp_lo into tmp_hi 5. Store tmp_hi to dst_hi
Example: r9 = (s8)r3 r9 and r3 are both stacked registers
ldr r6, [r11, #-16] // Load r3_lo into tmp_lo lsl r6, r6, #24 // Sign extend tmp_lo asr r6, r6, #24 // .. str r6, [r11, #-56] // Store tmp_lo to r9_lo asr r7, r6, #31 // Sign extend tmp_lo to tmp_hi str r7, [r11, #-52] // Store tmp_hi to r9_hi
Case B.2: src is stacked but dst is not: ---------------------------------------- 1. Load src_lo into dst_lo 2. Sign extend dst_lo according to offset. 3. Sign extend tmp_lo into dst_hi
Example: r6 = (s8)r3 r6 maps to {ARM_R5, ARM_R4} and r3 is stacked
ldr r4, [r11, #-16] // Load r3_lo to r6_lo lsl r4, r4, #24 // Sign extend r6_lo asr r4, r4, #24 // .. asr r5, r4, #31 // Sign extend r6_lo into r6_hi
Case B.3: src is not stacked but dst is stacked: ------------------------------------------------ 1. Sign extend src_lo into tmp_lo according to offset. 2. Store tmp_lo into dst_lo. 3. Sign extend src_lo into tmp_hi. 4. Store tmp_hi to dst_hi.
Example: r3 = (s8)r1 r3 is stacked and r1 maps to {ARM_R3, ARM_R2}
lsl r6, r2, #24 // Sign extend r1_lo to tmp_lo asr r6, r6, #24 // .. str r6, [r11, #-16] // Store tmp_lo to r3_lo asr r7, r6, #31 // Sign extend tmp_lo to tmp_hi str r7, [r11, #-12] // Store tmp_hi to r3_hi
Case B.4: Both src and dst are not stacked: ------------------------------------------- 1. Sign extend src_lo into dst_lo according to offset. 2. Sign extend dst_lo into dst_hi.
Example: r6 = (s8)r1 r6 maps to {ARM_R5, ARM_R4} and r1 maps to {ARM_R3, ARM_R2}
lsl r4, r2, #24 // Sign extend r1_lo to r6_lo asr r4, r4, #24 // .. asr r5, r4, #31 // Sign extend r6_lo to r6_hi

[ Upstream commit 5bcf0dcbf9066348058b88a510c57f70f384c92c ]
When redirecting a packet using XDP, the bpf_redirect_map() helper will set up the redirect destination information in struct bpf_redirect_info (using the __bpf_xdp_redirect_map() helper function), and the xdp_do_redirect() function will read this information after the XDP program returns and pass the frame on to the right redirect destination.
When using the BPF_F_BROADCAST flag to do multicast redirect to a whole map, __bpf_xdp_redirect_map() sets the 'map' pointer in struct bpf_redirect_info to point to the destination map to be broadcast. And xdp_do_redirect() reacts to the value of this map pointer to decide whether it's dealing with a broadcast or a single-value redirect. However, if the destination map is being destroyed before xdp_do_redirect() is called, the map pointer will be cleared out (by bpf_clear_redirect_map()) without waiting for any XDP programs to stop running. This causes xdp_do_redirect() to think that the redirect was to a single target, but the target pointer is also NULL (since broadcast redirects don't have a single target), so this causes a crash when a NULL pointer is passed to dev_map_enqueue().
To fix this, change xdp_do_redirect() to react directly to the presence of the BPF_F_BROADCAST flag in the 'flags' value in struct bpf_redirect_info to disambiguate between a single-target and a broadcast redirect. And only read the 'map' pointer if the broadcast flag is set, aborting if that has been cleared out in the meantime. This prevents the crash, while keeping the atomic (cmpxchg-based) clearing of the map pointer itself, and without adding any more checks in the non-broadcast fast path.

[ Upstream commit 1c5a1627f48105cbab81d25ec2f72232bfaa8185 ]
Commit 50e782a86c98 ("efi/unaccepted: Fix soft lockups caused by parallel memory acceptance") has released the spinlock so other CPUs can do memory acceptance in parallel and not triggers softlockup on other CPUs.
However the softlock up was intermittent shown up if the memory of the TD guest is large, and the timeout of softlockup is set to 1 second:
RIP: 0010:_raw_spin_unlock_irqrestore Call Trace: ? __hrtimer_run_queues <IRQ> ? hrtimer_interrupt ? watchdog_timer_fn ? __sysvec_apic_timer_interrupt ? __pfx_watchdog_timer_fn ? sysvec_apic_timer_interrupt </IRQ> ? __hrtimer_run_queues <TASK> ? hrtimer_interrupt ? asm_sysvec_apic_timer_interrupt ? _raw_spin_unlock_irqrestore ? __sysvec_apic_timer_interrupt ? sysvec_apic_timer_interrupt accept_memory try_to_accept_memory do_huge_pmd_anonymous_page get_page_from_freelist __handle_mm_fault __alloc_pages __folio_alloc ? __tdx_hypercall handle_mm_fault vma_alloc_folio do_user_addr_fault do_huge_pmd_anonymous_page exc_page_fault ? __do_huge_pmd_anonymous_page asm_exc_page_fault __handle_mm_fault
When the local irq is enabled at the end of accept_memory(), the softlockup detects that the watchdog on single CPU has not been fed for a while. That is to say, even other CPUs will not be blocked by spinlock, the current CPU might be stunk with local irq disabled for a while, which hurts not only nmi watchdog but also softlockup.
Chao Gao pointed out that the memory accept could be time costly and there was similar report before. Thus to avoid any softlocup detection during this stage, give the softlockup a flag to skip the timeout check at the end of accept_memory(), by invoking touch_softlockup_watchdog().

[ Upstream commit c7f7c37271787a7f77d7eedc132b0b419a76b4c8 ]
With the current thermal zone locking arrangement in the debugfs code, user space can open the "mitigations" file for a thermal zone before the zone's debugfs pointer is set which will result in a NULL pointer dereference in tze_seq_start().
Moreover, thermal_debug_tz_remove() is not called under the thermal zone lock, so it can run in parallel with the other functions accessing the thermal zone's struct thermal_debugfs object. Then, it may clear tz->debugfs after one of those functions has checked it and the struct thermal_debugfs object may be freed prematurely.
To address the first problem, pass a pointer to the thermal zone's struct thermal_debugfs object to debugfs_create_file() in thermal_debug_tz_add() and make tze_seq_start(), tze_seq_next(), tze_seq_stop(), and tze_seq_show() retrieve it from s->private instead of a pointer to the thermal zone object. This will ensure that tz_debugfs will be valid across the "mitigations" file accesses until thermal_debugfs_remove_id() called by thermal_debug_tz_remove() removes that file.
To address the second problem, use tz->lock in thermal_debug_tz_remove() around the tz->debugfs value check (in case the same thermal zone is removed at the same time in two different threads) and its reset to NULL.

[ Upstream commit 4b911a9690d72641879ea6d13cce1de31d346d79 ]
syzbot triggered various splats (see [0] and links) by a crafted GSO packet of VIRTIO_NET_HDR_GSO_UDP layering the following protocols:
ETH_P_8021AD + ETH_P_NSH + ETH_P_IPV6 + IPPROTO_UDP
NSH can encapsulate IPv4, IPv6, Ethernet, NSH, and MPLS. As the inner protocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), calls skb_mac_gso_segment() to invoke inner protocol GSO handlers.
nsh_gso_segment() does the following for the original skb before calling skb_mac_gso_segment()
1. reset skb->network_header 2. save the original skb->{mac_heaeder,mac_len} in a local variable 3. pull the NSH header 4. resets skb->mac_header 5. set up skb->mac_len and skb->protocol for the inner protocol.
and does the following for the segmented skb
6. set ntohs(ETH_P_NSH) to skb->protocol 7. push the NSH header 8. restore skb->mac_header 9. set skb->mac_header + mac_len to skb->network_header 10. restore skb->mac_len
There are two problems in 6-7 and 8-9.
(a) After 6 & 7, skb->data points to the NSH header, so the outer header (ETH_P_8021AD in this case) is stripped when skb is sent out of netdev.
Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH), skb_pull() in the first nsh_gso_segment() will make skb->data point to the middle of the outer NSH or Ethernet header because the Ethernet header is not pulled by the second nsh_gso_segment().
(b) While restoring skb->{mac_header,network_header} in 8 & 9, nsh_gso_segment() does not assume that the data in the linear buffer is shifted.
However, udp6_ufo_fragment() could shift the data and change skb->mac_header accordingly as demonstrated by syzbot.
If this happens, even the restored skb->mac_header points to the middle of the outer header.
It seems nsh_gso_segment() has never worked with outer headers so far.
At the end of nsh_gso_segment(), the outer header must be restored for the segmented skb, instead of the NSH header.

Drop the flow-hash of the skb when forwarding to the L2TP netdev.
This avoids the L2TP qdisc from using the flow-hash from the outer packet, which is identical for every flow within the tunnel.
This does not affect every platform but is specific for the ethernet driver. It depends on the platform including L4 information in the flow-hash.
One such example is the Mediatek Filogic MT798x family of networking processors.

Since thermal_debug_cdev_remove() does not run under cdev->lock, it can run in parallel with thermal_debug_cdev_state_update() and it may free the struct thermal_debugfs object used by the latter after it has been checked against NULL.
If that happens, thermal_debug_cdev_state_update() will access memory that has been freed already causing the kernel to crash.
Address this by using cdev->lock in thermal_debug_cdev_remove() around the cdev->debugfs value check (in case the same cdev is removed at the same time in two different threads) and its reset to NULL.

While there are two separate IRQ status bits for dock attach and detach, the hardware appears to mix them up more or less randomly, making them useless for tracking what actually happened. It is much safer to check the dock status separately and proceed based on that, as the old polling code did.
Note that the code assumes that only the dock can be hot-plugged - if other option card bits changed, the logic would break.

Pulled out of the next patch to improve its legibility.
As the function is now available, call it directly from snd_emu10k1_emu1010_init(), thus making the MicroDock firmware loading synchronous - there isn't really a reason not to. Note that this does not affect the AudioDocks of rev1 cards, as these have no independent power supplies, and thus come up only a while after the main card is initialized.
As a drive-by, adjust the priorities of two messages to better reflect their impact.

[ Upstream commit f848337cd801c7106a4ec0d61765771dab2a5909 ]
The actual event processing was already done by workqueue items. We can move the event dispatching there as well, rather than doing it already in the interrupt handler callback.
This change has a rather profound "side effect" on the reliability of the FPGA programming: once we enter programming mode, we must not issue any snd_emu1010_fpga_{read,write}() calls until we're done, as these would badly mess up the programming protocol. But exactly that would happen when trying to program the dock, as that triggers GPIO interrupts as a side effect. This is mitigated by deferring the actual interrupt handling, as workqueue items are not re-entrant.
To avoid scheduling the dispatcher on non-events, we now explicitly ignore GPIO IRQs triggered by "uninteresting" pins, which happens a lot as a side effect of calling snd_emu1010_fpga_{read,write}().

[ Upstream commit e8289fd3fa65d60cf04dab6f7845eda352c04ea6 ]
A side effect of making the dock monitoring interrupt-driven was that we'd be very quick to program a freshly connected dock. However, for unclear reasons, the dock does not work when we do that - despite the FPGA netlist upload going just fine. We work around this by adding a delay before programming the dock; for safety, the value is several times as much as was determined empirically.
Note that a badly timed dock hot-plug would have triggered the problem even before the referenced commit - but now it would happen 100% instead of about 3% of the time, thus making it impossible to work around by re-plugging.

VXLAN devices update their stats locklessly. Therefore these counters should either be stored in per-cpu data structures or the updates should be done using atomic increments.
Since the net_device_core_stats infrastructure is already used in vxlan_rcv(), use it for the other rx_dropped and tx_dropped counter updates. Update the other counters atomically using DEV_STATS_INC().

[ Upstream commit b11d26660dff8d7430892008616452dc8e5fb0f3 ]
With the AXG audio subsystem, there is a possible random channel shift on TDM capture, when the slot number per lane is more than 2, and there is more than one lane used.
The problem has been there since the introduction of the axg audio support but such scenario is pretty uncommon. This is why there is no loud complains about the problem.
Solving the problem require to make the links non-atomic and use the trigger() callback to start FEs and BEs in the appropriate order.
This was tried in the past and reverted because it caused the block irq to sleep while atomic. However, instead of reverting, the solution is to call snd_pcm_period_elapsed() in a non atomic context.
Use the bottom half of a threaded IRQ to do so.

Non atomic operations need to be performed in the trigger callback of the TDM interfaces. Those are BEs but what matters is the nonatomic flag of the FE in the DPCM context. Just set nonatomic for everything so, at least, what is done is clear.

So far, the formatters have been reset/enabled using the .prepare() callback. This was done in this callback because walking the formatters use a mutex. A mutex is used because formatter handling require dealing possibly slow clock operation.
With the support of non-atomic, .trigger() callback may be used which also allows to properly enable and disable formatters on start but also pause/resume.
This solve a random shift on TDMIN as well repeated samples on for TDMOUT.

Amlogic sound cards do create a lot of pcm interfaces, possibly more than 8. Some pcm interfaces are internal (like DPCM backends and c2c) and not exposed to userspace.
Those interfaces still increase the number passed to snd_find_free_minor(), which eventually exceeds 8 causing -EBUSY error on card registration if CONFIG_SND_DYNAMIC_MINORS=n and the interface is exposed to userspace.
select CONFIG_SND_DYNAMIC_MINORS for Amlogic cards to avoid the problem.

The selftest for the driver sends a dummy packet and checks if the packet will be received properly as it should be. The regular TX path and the selftest can use the same network queue so locking is required and was missing in the selftest path. This was addressed in the commit cited below. Unfortunately locking the TX queue requires BH to be disabled which is not the case in selftest path which is invoked in process context. Lockdep should be complaining about this.
Use __netif_tx_lock_bh() for TX queue locking.

The find connection logic of Transarc's Rx was modified in the mid-1990s to support multi-homed servers which might send a response packet from an address other than the destination address in the received packet. The rules for accepting a packet by an Rx initiator (RX_CLIENT_CONNECTION) were altered to permit acceptance of a packet from any address provided that the port number was unchanged and all of the connection identifiers matched (Epoch, CID, SecurityClass, ...).
This change applies the same rules to the Linux implementation which makes it consistent with IBM AFS 3.6, Arla, OpenAFS and AuriStorFS.

Ensure the inner IP header is part of skb's linear data before reading its ECN bits. Otherwise we might read garbage. One symptom is the system erroneously logging errors like "vxlan: non-ECT from xxx.xxx.xxx.xxx with TOS=xxxx".
Similar bugs have been fixed in geneve, ip_tunnel and ip6_tunnel (see commit 1ca1ba465e55 ("geneve: make sure to pull inner header in geneve_rx()") for example). So let's reuse the same code structure for consistency. Maybe we'll can add a common helper in the future.

Analysis: There is one napi structure per out_q: card->qdio.out_qs[i].napi The napi.poll functions are set during qeth_open().
Since commit 1cfef80d4c2b ("s390/qeth: Don't call dev_close/dev_open (DOWN/UP)") qeth_set_offline()/qeth_set_online() no longer call dev_close()/ dev_open(). So if qeth_free_qdio_queues() cleared card->qdio.out_qs[i].napi.poll while the network interface was UP and the card was offline, they are not set again.
Reproduction: chzdev -e $devno layer2=0 ip link set dev $network_interface up echo 0 > /sys/bus/ccwgroup/devices/0.0.$devno/online echo foo > /sys/bus/ccwgroup/devices/0.0.$devno/hsuid echo 1 > /sys/bus/ccwgroup/devices/0.0.$devno/online -> Crash (can be enforced e.g. by af_iucv connect(), ip link down/up, ...)
Note that a Completion Queue (CQ) is only enabled or disabled, when hsuid is set for the first time or when it is removed.
Workarounds: - Set hsuid before setting the device online for the first time or - Use chzdev -d $devno; chzdev $devno hsuid=xxx; chzdev -e $devno; to set hsuid on an existing device. (this will remove and recreate the network interface)
Fix: There is no need to free the output queues when a completion queue is added or removed. card->qdio.state now indicates whether the inbound buffer pool and the outbound queues are allocated. card->qdio.c_q indicates whether a CQ is allocated.

GPIO controller might not be available when driver is being probed. There are plenty of reasons why, one of which is deferred probe.
Since GPIOs are optional, return any error code we got to the upper layer, including deferred probe. With that in mind, use dev_err_probe() in order to avoid spamming the logs.

[ Upstream commit fc1092f51567277509563800a3c56732070b6aa4 ]
KMSAN reported uninit-value access in __ip_make_skb() [1]. __ip_make_skb() tests HDRINCL to know if the skb has icmphdr. However, HDRINCL can cause a race condition. If calling setsockopt(2) with IP_HDRINCL changes HDRINCL while __ip_make_skb() is running, the function will access icmphdr in the skb even if it is not included. This causes the issue reported by KMSAN.
Check FLOWI_FLAG_KNOWN_NH on fl4->flowi4_flags instead of testing HDRINCL on the socket.
Also, fl4->fl4_icmp_type and fl4->fl4_icmp_code are not initialized. These are union in struct flowi4 and are implicitly initialized by flowi4_init_output(), but we should not rely on specific union layout.
Initialize these explicitly in raw_sendmsg().

[ Upstream commit 5ef31ea5d053a8f493a772ebad3f3ce82c35d845 ]
Commits a602456 ("udp: Add GRO functions to UDP socket") and 57c67ff ("udp: additional GRO support") introduce incorrect usage of {ip,ipv6}_hdr in the complete phase of gro. The functions always return skb->network_header, which in the case of encapsulated packets at the gro complete phase, is always set to the innermost L3 of the packet. That means that calling {ip,ipv6}_hdr for skbs which completed the GRO receive phase (both in gro_list and *_gro_complete) when parsing an encapsulated packet's _outer_ L3/L4 may return an unexpected value.
This incorrect usage leads to a bug in GRO's UDP socket lookup. udp{4,6}_lib_lookup_skb functions use ip_hdr/ipv6_hdr respectively. These *_hdr functions return network_header which will point to the innermost L3, resulting in the wrong offset being used in __udp{4,6}_lib_lookup with encapsulated packets.
This patch adds network_offset and inner_network_offset to napi_gro_cb, and makes sure both are set correctly.
To fix the issue, network_offsets union is used inside napi_gro_cb, in which both the outer and the inner network offsets are saved.
Reproduction example:
Endpoint configuration example (fou + local address bind)
# ip fou add port 6666 ipproto 4 # ip link add name tun1 type ipip remote 2.2.2.1 local 2.2.2.2 encap fou encap-dport 5555 encap-sport 6666 mode ipip # ip link set tun1 up # ip a add 1.1.1.2/24 dev tun1

Contrary to i915, in xe ADL-N is kept as a different platform, not a subplatform of ADL-P. Since the display side doesn't need to differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called, just fixup the compat header to check for both P and N.
Moving ADL-N to be a subplatform would be more complex as the firmware loading in xe only handles platforms, not subplatforms, as going forward the direction is to check on IP version rather than platforms/subplatforms.
Fix warning when initializing display:
xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH ------------[ cut here ]------------ xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P))
And wrong paths being taken on the display side.

While PLL CPUX clock rate change when CPU is running from it works in vast majority of cases, now and then it causes instability. This leads to system crashes and other undefined behaviour. After a lot of testing (30+ hours) while also doing a lot of frequency switches, we can't observe any instability issues anymore when doing reparenting to stable clock like 24 MHz oscillator.

At the time of LPAR boot up, partition firmware provides Open Firmware property ibm,dma-window for the PE. This property is provided on the PCI bus the PE is attached to.
There are execptions where the partition firmware might not provide this property for the PE at the time of LPAR boot up. One of the scenario is where the firmware has frozen the PE due to some error condition. This PE is frozen for 24 hours or unless the whole system is reinitialized.
Within this time frame, if the LPAR is booted, the frozen PE will be presented to the LPAR but ibm,dma-window property could be missing.
Today, under these circumstances, the LPAR oopses with NULL pointer dereference, when configuring the PCI bus the PE is attached to.

vgic_v2_parse_attr() is responsible for finding the vCPU that matches the user-provided CPUID, which (of course) may not be valid. If the ID is invalid, kvm_get_vcpu_by_id() returns NULL, which isn't handled gracefully.
Similar to the GICv3 uaccess flow, check that kvm_get_vcpu_by_id() actually returns something and fail the ioctl if not.

[ Upstream commit 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c ]
There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric.
Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch.
Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent.

IRQF_ONESHOT is found to mask HBA generated interrupts when thread_fn is running. As a result, some EQEs/CQEs miss timely processing resulting in SCSI layer attempts to abort commands due to io_timeout. Abort CQEs are also not processed leading to the observations of hangs and spam of "0748 abort handler timed out waiting for aborting I/O" log messages.
Remove the IRQF_ONESHOT flag. The cmpxchg and xchg atomic operations on lpfc_queue->queue_claimed already protect potential parallel access to an EQ/CQ should the thread_fn get interrupted by the primary irq handler.

Typically when an out of resource CQE status is detected, the lpfc_ramp_down_queue_handler() logic is called to help reduce I/O load by reducing an sdev's queue_depth.
However, the current lpfc_rampdown_queue_depth() logic does not help reduce queue_depth. num_cmd_success is never updated and is always zero, which means new_queue_depth will always be set to sdev->queue_depth. So, new_queue_depth = sdev->queue_depth - new_queue_depth always sets new_queue_depth to zero. And, scsi_change_queue_depth(sdev, 0) is essentially a no-op.
Change the lpfc_ramp_down_queue_handler() logic to set new_queue_depth equal to sdev->queue_depth subtracted from number of times num_rsrc_err was incremented. If num_rsrc_err is >= sdev->queue_depth, then set new_queue_depth equal to 1. Eventually, the frequency of Good_Status frames will signal SCSI upper layer to auto increase the queue_depth back to the driver default of 64 via scsi_handle_queue_ramp_up().

In punch_hole(), when the offset lies in the final block for a given height, there is no hole to punch, but the maximum size check fails to detect that. Consequently, punch_hole() will try to punch a hole beyond the end of the metadata and fail. Fix the maximum size check.

[ Upstream commit 6630036b7c228f57c7893ee0403e92c2db2cd21d ]
If an iget fails due to not being able to retrieve information from the server then the inode structure is only partially initialized. When the inode gets evicted, references to uninitialized structures (like fscache cookies) were being made.
This patch checks for a bad_inode before doing anything other than clearing the inode from the cache. Since the inode is bad, it shouldn't have any state associated with it that needs to be written back (and there really isn't a way to complete those anyways).

mips declares an END macro in its headers so it can't be used without namespace in a driver like xe.
Instead of coming up with a longer name, just remove the macro and replace its use with 0 since it's still clear what that means: set_offsets() was already using that implicitly when checking the data variable.

[ Upstream commit 429846b4b6ce9853e0d803a2357bb2e55083adf0 ]
When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver prints this WARNING message:
memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1) WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8 replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended to be a flexible length array, so the WARN is a false positive.
To suppress the WARN, remove the constant number '1' from the array declaration and clarify that it has flexible length. Also, adjust the memory allocation size to match the change.

The session resources are used by FW and driver when session is offloaded, once session is uploaded these resources are not used. The lock is not required as these fields won't be used any longer. The offload and upload calls are sequential, hence lock is not required.
This will suppress following BUG_ON():

[ Upstream commit 2f1aeab9fca1a5f583be1add175d1ee95c213cfa ]
When attempting to exclusive open a device which has no exclusive open permission, such as a physical device associated with the flakey dm device, the open operation will fail, resulting in a mount failure.
In this particular scenario, we erroneously return -EINVAL instead of the correct error code provided by the bdev_open_by_path() function, which is -EBUSY.
Fix this, by returning error code from the bdev_open_by_path() function. With this correction, the mount error message will align with that of ext4 and xfs.

[ Upstream commit a8d89feba7e54e691ca7c4efc2a6264fa83f3687 ]
This patch adds a missing check to bloom filter creating, rejecting values above KMALLOC_MAX_SIZE. This brings the bloom map in line with many other map types.
The lack of this protection can cause kernel crashes for value sizes that overflow int's. Such a crash was caught by syzkaller. The next patch adds more guard-rails at a lower level.

[ Upstream commit 8ecab2e64572f1aecdfc5a8feae748abda6e3347 ]
The event filter function test has been failing in our internal test farm:
| # not ok 33 event filter function - test event filtering on functions
Running the test in verbose mode indicates that this is because the test erroneously determines that kmem_cache_free() is the most common caller of kmem_cache_free():
# # + cut -d: -f3 trace # # + sed s/call_site=([^+]*)+0x.*/1/ # # + sort # # + uniq -c # # + sort # # + tail -n 1 # # + sed s/^[ 0-9]*// # # + target_func=kmem_cache_free
... and as kmem_cache_free() doesn't call itself, setting this as the filter function for kmem_cache_free() results in no hits, and consequently the test fails:
# # + grep kmem_cache_free trace # # + grep kmem_cache_free # # + wc -l # # + hitcnt=0 # # + grep kmem_cache_free trace # # + grep -v kmem_cache_free # # + wc -l # # + misscnt=0 # # + [ 0 -eq 0 ] # # + exit_fail
This seems to be because the system in question has tasks with ':' in their name (which a number of kernel worker threads have). These show up in the trace, e.g.
test:.sh-1299 [004] ..... 2886.040608: kmem_cache_free: call_site=putname+0xa4/0xc8 ptr=000000000f4d22f4 name=names_cache
... and so when we try to extact the call_site with:
cut -d: -f3 trace | sed 's/call_site=([^+]*)+0x.*/\1/'
... the 'cut' command will extrace the column containing 'kmem_cache_free' rather than the column containing 'call_site=...', and the 'sed' command will leave this unchanged. Consequently, the test will decide to use 'kmem_cache_free' as the filter function, resulting in the failure seen above.
Fix this by matching the 'call_site=<func>' part specifically to extract the function name.

[ Upstream commit 54babdc0343fff2f32dfaafaaa9e42c4db278204 ]
When KCSAN and CONSTRUCTORS are enabled, one can trigger the
"Unpatched return thunk in use. This should not happen!"
catch-all warning.
Usually, when objtool runs on the .o objects, it does generate a section .return_sites which contains all offsets in the objects to the return thunks of the functions present there. Those return thunks then get patched at runtime by the alternatives.
KCSAN and CONSTRUCTORS add this to the object file's .text.startup section:
------------------- Disassembly of section .text.startup:
...
0000000000000010 <_sub_I_00099_0>: 10: f3 0f 1e fa endbr64 14: e8 00 00 00 00 call 19 <_sub_I_00099_0+0x9> 15: R_X86_64_PLT32 __tsan_init-0x4 19: e9 00 00 00 00 jmp 1e <__UNIQUE_ID___addressable_cryptd_alloc_aead349+0x6> 1a: R_X86_64_PLT32 __x86_return_thunk-0x4 -------------------
which, if it is built as a module goes through the intermediary stage of creating a <module>.mod.c file which, when translated, receives a second constructor:
------------------- Disassembly of section .text.startup:
0000000000000010 <_sub_I_00099_0>: 10: f3 0f 1e fa endbr64 14: e8 00 00 00 00 call 19 <_sub_I_00099_0+0x9> 15: R_X86_64_PLT32 __tsan_init-0x4 19: e9 00 00 00 00 jmp 1e <_sub_I_00099_0+0xe> 1a: R_X86_64_PLT32 __x86_return_thunk-0x4
...
0000000000000030 <_sub_I_00099_0>: 30: f3 0f 1e fa endbr64 34: e8 00 00 00 00 call 39 <_sub_I_00099_0+0x9> 35: R_X86_64_PLT32 __tsan_init-0x4 39: e9 00 00 00 00 jmp 3e <__ksymtab_cryptd_alloc_ahash+0x2> 3a: R_X86_64_PLT32 __x86_return_thunk-0x4 -------------------
in the .ko file.
Objtool has run already so that second constructor's return thunk cannot be added to the .return_sites section and thus the return thunk remains unpatched and the warning rightfully fires.
Drop KCSAN flags from the mod.c generation stage as those constructors do not contain data races one would be interested about.

[ Upstream commit 6bc5e70b1c792b31b497e48b4668a9a2909aca0d ]
When wl suspend error occurs, for example BKOP or SSU timeout, the host triggers an error handler and returns -EBUSY to break the wl suspend process. However, it is possible for the runtime PM to enter wl suspend again before the error handler has finished, and return -EINVAL because the device is in an error state. To address this, ensure that the rumtime PM waits for the error handler to finish, or trigger the error handler in such cases, because returning -EINVAL can cause the I/O to hang.

[ Upstream commit e675a4fd6d1f8990d3bed5dada3d20edfa000423 ]
This series [1] reduced the kmalloc() minimum alignment on arm64 to 8 bytes (from 128). In libsas, this will cause SMP requests to be 8-byte aligned through kmalloc() allocation. However, for hisi_sas hardware, all command addresses must be 16-byte-aligned. Otherwise, the commands fail to be executed.
ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA operations, so use ARCH_DMA_MINALIGN as the alignment for SMP request.

When a dev command times out in MCQ mode, a successfully cleared command should cause a retry. However, because we currently return 0, the caller considers the command a success which causes the following error to be logged: "Invalid offset 0x0 in descriptor IDN 0x9, length 0x0".
Retry if clearing the command was successful.

For shutting up spurious KMSAN uninit-value warnings, just replace kmalloc() calls with kzalloc() for the buffers used for communications. There should be no real issue with the original code, but it's still better to cover.

And we fixed the button detection error by disabling the button detection feature when the headphone are unplugged and enabling it when headphone are plugged in.

If the RBUF logic is not reset when the kernel starts then there may be some data left over from any network boot loader. If the 64-byte packet headers are enabled then this can be fatal.
Extend bcmgenet_dma_disable to do perform the reset, but not when called from bcmgenet_resume in order to preserve a wake packet.
N.B. This different handling of resume is just based on a hunch - why else wouldn't one reset the RBUF as well as the TBUF? If this isn't the case then it's easy to change the patch to make the RBUF reset unconditional.

[ Upstream commit 752e3c53de0fa3b7d817a83050b6699b8e9c6ec9 ]
In the FireWire OHCI interrupt handler, if a bus reset interrupt has occurred, mask bus reset interrupts until bus_reset_work has serviced and cleared the interrupt.
Normally, we always leave bus reset interrupts masked. We infer the bus reset from the self-ID interrupt that happens shortly thereafter. A scenario where we unmask bus reset interrupts was introduced in 2008 in a007bb857e0b26f5d8b73c2ff90782d9c0972620: If OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we will unmask bus reset interrupts so we can log them.
irq_handler logs the bus reset interrupt. However, we can't clear the bus reset event flag in irq_handler, because we won't service the event until later. irq_handler exits with the event flag still set. If the corresponding interrupt is still unmasked, the first bus reset will usually freeze the system due to irq_handler being called again each time it exits. This freeze can be reproduced by loading firewire_ohci with "modprobe firewire_ohci debug=-1" (to enable all debugging output). Apparently there are also some cases where bus_reset_work will get called soon enough to clear the event, and operation will continue normally.
This freeze was first reported a few months after a007bb85 was committed, but until now it was never fixed. The debug level could safely be set to -1 through sysfs after the module was loaded, but this would be ineffectual in logging bus reset interrupts since they were only unmasked during initialization.
irq_handler will now leave the event flag set but mask bus reset interrupts, so irq_handler won't be called again and there will be no freeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will unmask the interrupt after servicing the event, so future interrupts will be caught as desired.
As a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be enabled through sysfs in addition to during initial module loading. However, when enabled through sysfs, logging of bus reset interrupts will be effective only starting with the second bus reset, after bus_reset_work has executed.

[ Upstream commit 3ac1d14d0583a2de75d49a5234d767e2590384dd ]
When running turbostat, a system with 512 cpus reaches the limit for maximum number of file descriptors that can be opened. To solve this problem, the limit is raised to 2^15, which is a large enough number.
Below data is collected from AMD server systems while running turbostat:
|-----------+-------------------------------| | # of cpus | # of opened fds for turbostat | |-----------+-------------------------------| | 128 | 260 | |-----------+-------------------------------| | 192 | 388 | |-----------+-------------------------------| | 512 | 1028 | |-----------+-------------------------------|
So, the new max limit would be sufficient up to 2^14 cpus (but this also depends on how many counters are enabled).

[ Upstream commit 227ed18f456a68bbb69807294a9089208663a6d3 ]
turbostat prints the abnormal SYS%LPI across suspend-to-idle: SYS%LPI = 114479815993277.50
This is reproduced by: Run a freeze cycle, e.g. "sleepgraph -m freeze -rtcwake 15". Then do a reboot. After boot up, launch the suspend-idle-idle and check the SYS%LPI field.
The slp_so residence counter is in LPIT table, and BIOS does not clears this register across reset. The PMC expects the OS to calculate the LPI residency based on the delta. However, there is an firmware issue that the LPIT gets cleared to 0 during the second suspend to idle after the reboot, which brings negative delta value.

Previously a failed read of /dev/cpu_dma_latency erroneously complained turbostat: capget(CAP_SYS_ADMIN) failed, try "# setcap cap_sys_admin=ep ./turbostat
This went unnoticed because this file is typically visible to root, and turbostat was typically run as root.
Going forward, when a non-root user can run turbostat... Complain about failed read access to this file only if --debug is used.

Currently, this call site in btrfs_clear_delalloc_extent() only converts the reservation. We are marking it not delalloc, so I don't think it makes sense to keep the rsv around. This is a path where we are not sure to join a transaction, so it leads to incorrect free-ing during umount.
Helps with the pass rate of generic/269 and generic/475.

We find that some disks use D2H frame instead of SDB frame to return NCQ error. Currently, only the I/O corresponding to the D2H frame is processed in this scenario, which does not meet the processing requirements of the NCQ error scenario. So we set dev_status to HISI_SAS_DEV_NCQ_ERR and abort all I/Os of the disk in this scenario.

Avoid that undefined behavior by simply taking the "delay = 0" branch if the shift is too large.
I am not sure what the symptoms of an undefined value delay will be, but I suspect it could be more than a little annoying to debug.

The host1x devices are virtual compound devices and do not perform DMA accesses themselves, so they do not need to be set up for DMA.
Ideally we would also not need to set up DMA masks for the virtual devices, but we currently still need those for legacy support on old hardware.

[ Upstream commit 4370b673ccf240bf7587b0cb8e6726a5ccaf1f17 ]
thread_info.syscall is used by syscall_get_nr to supply syscall nr over a thread stack frame.
Previously, thread_info.syscall is only saved at syscall_trace_enter when syscall tracing is enabled. However rest of the kernel code do expect syscall_get_nr to be available without syscall tracing. The previous design breaks collect_syscall.
Move saving process to syscall entry to fix it.

Running turbostat on a 16 socket HPE Scale-up Compute 3200 (SapphireRapids) fails with: turbostat: /sys/devices/system/cpu/intel_uncore_frequency/package_010_die_00/current_freq_khz: open failed: No such file or directory
We observe the sysfs uncore frequency directories named: ... package_09_die_00/ package_10_die_00/ package_11_die_00/ ... package_15_die_00/
The culprit is an incorrect sprintf format string "package_0%d_die_0%d" used with each instance of reading uncore frequency files. uncore-frequency-common.c creates the sysfs directory with the format "package_%02d_die_%02d". Once the package value reaches double digits, the formats diverge.
Change each instance of "package_0%d_die_0%d" to "package_%02d_die_%02d".

copy_from_sockptr() helper is unsafe, unless callers did the prior check against user provided optlen.
Too many callers get this wrong, lets add a helper to fix them and avoid future copy/paste bugs.
Instead of :
if (optlen < sizeof(opt)) { err = -EINVAL; break; } if (copy_from_sockptr(&opt, optval, sizeof(opt)) { err = -EFAULT; break; }
Use :
err = copy_safe_from_sockptr(&opt, sizeof(opt), optval, optlen); if (err) break;

If there are more than one device doing reset in parallel, the first device will call kfd_suspend_all_processes() to evict all processes on all devices, this call takes time to finish. other device will start reset and recover without waiting. if the process has not been evicted before doing recover, it will be restored, then caused page fault.

[ Upstream commit 076361362122a6d8a4c45f172ced5576b2d4a50d ]
The struct adjtimex freq field takes a signed value who's units are in shifted (<<16) parts-per-million.
Unfortunately for negative adjustments, the straightforward use of:
freq = ppm << 16 trips undefined behavior warnings with clang:
valid-adjtimex.c:66:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value] -499<<16, ~~~~^ valid-adjtimex.c:67:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value] -450<<16, ~~~~^ ..
Fix it by using a multiply by (1 << 16) instead of shifting negative values in the valid-adjtimex test case. Align the values for better readability.

Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues.
In order to make sure callers of vmbus_establish_gpadl() and vmbus_teardown_gpadl() don't return decrypted/shared pages to allocators, add a field in struct vmbus_gpadl to keep track of the decryption status of the buffers. This will allow the callers to know if they should free or leak the pages.

[ Upstream commit 35f834265e0dc78b003aa0d1af65cafb89666b76 ]
There are various use cases that are becoming more common in which password changes are scheduled on a server(s) periodically but the clients connected to this server need to stay connected (even in the face of brief network reconnects) due to mounts which can not be easily unmounted and mounted at will, and servers that do password rotation do not always have the ability to tell the clients exactly when to the new password will be effective, so add support for an alt password ("password2=") on mount (and also remount) so that we can anticipate the upcoming change to the server without risking breaking existing mounts.
An alternative would have been to use the kernel keyring for this but the processes doing the reconnect do not have access to the keyring but do have access to the ses structure.

I'm not sure why this check was ever here. After updating to 6.6 I suddenly found caching had been turned on by default and neither cache=none nor the new directio would turn it off. After walking through the new code very manually I realized that it's because the caching has to be, in effect, turned off explicitly by setting P9L_DIRECT and whenever a file has a flag, in my case QTAPPEND, it doesn't get set.
Setting aside QTDIR which seems to ignore the new fid->mode entirely, the rest of these either should be subject to the same cache rules as every other QTFILE or perhaps very explicitly not cached in the case of QTAUTH.

[ Upstream commit 69630926011c1f7170a465b7b5c228deb66e9372 ]
The chacha-p10-crypto module provides optimised chacha routines for Power10. It also selects CRYPTO_ARCH_HAVE_LIB_CHACHA which says it provides chacha_crypt_arch() to generic code.
Notably the module needs to provide chacha_crypt_arch() regardless of whether it is loaded on Power10 or an older CPU.
The implementation of chacha_crypt_arch() already has a fallback to chacha_crypt_generic(), however the module as a whole fails to load on pre-Power10, because of the use of module_cpu_feature_match().
This breaks for example loading wireguard:
jostaberry-1:~ # modprobe -v wireguard insmod /lib/modules/6.8.0-lp155.8.g7e0e887-default/kernel/arch/powerpc/crypto/chacha-p10-crypto.ko.zst modprobe: ERROR: could not insert 'wireguard': No such device
Fix it by removing module_cpu_feature_match(), and instead check the CPU feature manually. If the CPU feature is not found, the module still loads successfully, but doesn't register the Power10 specific algorithms. That allows chacha_crypt_generic() to remain available for use, fixing the problem.

[ Upstream commit 6f63af7511e7058f3fa4ad5b8102210741c9f947 ]
We don't need to hold the prepare_lock when dropping a ref on a struct clk_core. The release function is only freeing memory and any code with a pointer reference has already unlinked anything pointing to the clk_core. This reduces the holding area of the prepare_lock a bit.
Note that we also don't call free_clk() with the prepare_lock held. There isn't any reason to do that.

In 9p2000 legacy mode, stat2inode initializes nlink to 1, which is redundant with what alloc_inode should have already set. 9p2000.u overrides this with extensions if present in the stat structure, and 9p2000.L incorporates nlink into its stat structure.
At the very least this probably messes with directory nlink accounting in legacy mode.

I didn't pay close enough attention the last time I tried to fix this problem - while we currently do correctly take care to make sure we don't probe a connected eDP port more then once, we don't do the same thing for eDP ports we found to be disconnected.
So, fix this and make sure we only ever probe eDP ports once and then leave them at that connector state forever (since without HPD, it's not going to change on its own anyway). This should get rid of the last few GSP errors getting spit out during runtime suspend and resume on some machines, as we tried to reprobe eDP ports in response to ACPI hotplug probe events.

In iocg_pay_debt(), warn is triggered if 'active_list' is empty, which is intended to confirm iocg is active when it has debt. However, warn can be triggered during a blkcg or disk removal, if iocg_waitq_timer_fn() is run at that time:
WARNING: CPU: 0 PID: 2344971 at block/blk-iocost.c:1402 iocg_pay_debt+0x14c/0x190 Call trace: iocg_pay_debt+0x14c/0x190 iocg_kick_waitq+0x438/0x4c0 iocg_waitq_timer_fn+0xd8/0x130 __run_hrtimer+0x144/0x45c __hrtimer_run_queues+0x16c/0x244 hrtimer_interrupt+0x2cc/0x7b0
The warn in this situation is meaningless. Since this iocg is being removed, the state of the 'active_list' is irrelevant, and 'waitq_timer' is canceled after removing 'active_list' in ioc_pd_free(), which ensures iocg is freed after iocg_waitq_timer_fn() returns.
Therefore, add the check if iocg was already offlined to avoid warn when removing a blkcg or disk.

[ Upstream commit 58fbfecab965014b6e3cc956a76b4a96265a1add ]
The software GRO path for esp transport mode uses skb_mac_header_rebuild prior to re-injecting the packet via the xfrm_napi_dev. This only copies skb->mac_len bytes of header which may not be sufficient if the packet contains 802.1Q tags or other VLAN tags. Worse copying only the initial header will leave a packet marked as being VLAN tagged but without the corresponding tag leading to mangling when it is later untagged.
The VLAN tags are important when receiving the decrypted esp transport mode packet after GRO processing to ensure it is received on the correct interface.
Therefore record the full mac header length in xfrm*_transport_input for later use in corresponding xfrm*_transport_finish to copy the entire mac header when rebuilding the mac header for GRO. The skb->data pointer is left pointing skb->mac_header bytes after the start of the mac header as is expected by the network stack and network and transport header offsets reset to this location.

We find the root cause of this OOB is that arm does not clear stale stack poison in the case of cpuidle.
This patch refer to arch/arm64/kernel/sleep.S to resolve this issue.
From cited commit [1] that explain the problem
Functions which the compiler has instrumented for KASAN place poison on the stack shadow upon entry and remove this poison prior to returning.
In the case of cpuidle, CPUs exit the kernel a number of levels deep in C code. Any instrumented functions on this critical path will leave portions of the stack shadow poisoned.
If CPUs lose context and return to the kernel via a cold path, we restore a prior context saved in __cpu_suspend_enter are forgotten, and we never remove the poison they placed in the stack shadow area by functions calls between this and the actual exit of the kernel.
Thus, (depending on stackframe layout) subsequent calls to instrumented functions may hit this stale poison, resulting in (spurious) KASAN splats to the console.
To avoid this, clear any stale poison from the idle thread for a CPU prior to bringing a CPU online.

TCP_SYN_RECV state is really special, it is only used by cross-syn connections, mostly used by fuzzers.
In the following crash [1], syzbot managed to trigger a divide by zero in tcp_rcv_space_adjust()
A socket makes the following state transitions, without ever calling tcp_init_transfer(), meaning tcp_init_buffer_space() is also not called.
TCP_CLOSE connect() TCP_SYN_SENT TCP_SYN_RECV shutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN) TCP_FIN_WAIT1
To fix this issue, change tcp_shutdown() to not perform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition, which makes no sense anyway.
When tcp_rcv_state_process() later changes socket state from TCP_SYN_RECV to TCP_ESTABLISH, then look at sk->sk_shutdown to finally enter TCP_FIN_WAIT1 state, and send a FIN packet from a sane socket state.
This means tcp_send_fin() can now be called from BH context, and must use GFP_ATOMIC allocations.

[ Upstream commit f2db7230f73a80dbb179deab78f88a7947f0ab7e ]
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique() with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to reuse the port during connect() and call sock_hold() in tcp_twsk_unique() for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten and sock_put() will cause underflow, triggering a real use-after-free somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in tcp_twsk_unique() and give up on reusing the port if it returns false.

[ Upstream commit 483bc08181827fc475643272ffb69c533007e546 ]
When the sco connection is established and then, the sco socket is releasing, timeout_work will be scheduled to judge whether the sco disconnection is timeout. The sock will be deallocated later, but it is dereferenced again in sco_sock_timeout. As a result, the use-after-free bugs will happen. The root cause is shown below:
Cleanup Thread | Worker Thread sco_sock_release | sco_sock_close | __sco_sock_close | sco_sock_set_timer | schedule_delayed_work | sco_sock_kill | (wait a time) sock_put(sk) //FREE | sco_sock_timeout | sock_hold(sk) //USE

Fix this problem by adding a check protected by sco_conn_lock to judget whether the conn->hcon is null. Because the conn->hcon will be set to null, when the sock is releasing.

Tying the msft->data lifetime to hdev by freeing it in hci_release_dev() to fix the following case:
[use] msft_do_close() msft = hdev->msft_data; if (!msft) ...(1) <- passed. return; mutex_lock(&msft->filter_lock); ...(4) <- used after freed.
[free] msft_unregister() msft = hdev->msft_data; hdev->msft_data = NULL; ...(2) kfree(msft); ...(3) <- msft is freed.

Bluetooth is not a random device connected to the MMC/SD controller. It is function 2 of the SDIO device.
Fix the address of the bluetooth node. Also fix the node name and drop the label.

There is a race condition between l2cap_chan_timeout() and l2cap_chan_del(). When we use l2cap_chan_del() to delete the channel, the chan->conn will be set to null. But the conn could be dereferenced again in the mutex_lock() of l2cap_chan_timeout(). As a result the null pointer dereference bug will happen. The KASAN report triggered by POC is shown below:

[ Upstream commit e0863634bf9f7cf36291ebb5bfa2d16632f79c49 ]
Currently the driver uses local_bh_disable()/local_bh_enable() in its IRQ handler to avoid triggering net_rx_action() softirq on exit from netif_rx(). The net_rx_action() could trigger this driver .start_xmit callback, which is protected by the same lock as the IRQ handler, so calling the .start_xmit from netif_rx() from the IRQ handler critical section protected by the lock could lead to an attempt to claim the already claimed lock, and a hang.
The local_bh_disable()/local_bh_enable() approach works only in case the IRQ handler is protected by a spinlock, but does not work if the IRQ handler is protected by mutex, i.e. this works for KS8851 with Parallel bus interface, but not for KS8851 with SPI bus interface.
Remove the BH manipulation and instead of calling netif_rx() inside the IRQ handler code protected by the lock, queue all the received SKBs in the IRQ handler into a queue first, and once the IRQ handler exits the critical section protected by the lock, dequeue all the queued SKBs and push them all into netif_rx(). At this point, it is safe to trigger the net_rx_action() softirq, since the netif_rx() call is outside of the lock that protects the IRQ handler.

Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a struct ifla_vf_vlan_info so the size of such attribute needs to be at least of sizeof(struct ifla_vf_vlan_info) which is 14 bytes. The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes) which is less than sizeof(struct ifla_vf_vlan_info) so this validation is not enough and a too small attribute might be cast to a struct ifla_vf_vlan_info, this might result in an out of bands read access when accessing the saved (casted) entry in ivvl.

Introduce cmd_buffer, a separate buffer for storing only the command that is sent to the device. Before this separation, the existing buffer was shared for both the command and the report received in ccp_raw_event(), which was copied into it.
However, because of hidraw, the raw event parsing may be triggered in the middle of sending a command, resulting in outputting gibberish to the device. Using a separate buffer resolves this.

[ Upstream commit d02abd57e79469a026213f7f5827a98d909f236a ]
Through hidraw, userspace can cause a status report to be sent from the device. The parsing in ccp_raw_event() may happen in parallel to a send_usb_cmd() call (which resets the completion for tracking the report) if it's running on a different CPU where bottom half interrupts are not disabled.
Add a spinlock around the complete_all() in ccp_raw_event() and reinit_completion() in send_usb_cmd() to prevent race issues.

[ Upstream commit 9a169c267e946b0f47f67e8ccc70134708ccf3d4 ]
When creating the topology for the test, three veth pairs are created in the initial network namespace before being moved to one of the network namespaces created by the test.
On systems where systemd-udev uses MACAddressPolicy=persistent (default since systemd version 242), this will result in some net devices having the same MAC address since they were created with the same name in the initial network namespace. In turn, this leads to arping / ndisc6 failing since packets are dropped by the bridge's loopback filter.
Fix by creating each net device in the correct network namespace instead of moving it there from the initial network namespace.

[ Upstream commit ba4e103848d3a2a28a0445e39f4a9564187efe54 ]
Make the following fixes to the congestion control algorithm:
(1) Don't vary the cwnd starting value by the size of RXRPC_TX_SMSS since that's currently held constant - set to the size of a jumbo subpacket payload so that we can create jumbo packets on the fly. The current code invariably picks 3 as the starting value.
Further, the starting cwnd needs to be an even number because we ack every other packet, so set it to 4.
(2) Don't cut ssthresh when we see an ACK come from the peer with a receive window (rwind) less than ssthresh. ssthresh keeps track of characteristics of the connection whereas rwind may be reduced by the peer for any reason - and may be reduced to 0.

[ Upstream commit 012b7206918dcc5a4dcf1432b3e643114c95957e ]
Only generate one ACK packet for all the subpackets in a jumbo packet. If we would like to generate more than one ACK, we prioritise them base on their reason code, in the order, highest first:
OutOfSeq > NoSpace > ExceedsWin > Duplicate > Requested > Delay > Idle
For the first four, we reference the lowest offending subpacket; for the last three, the highest.
This reduces the number of ACKs we end up transmitting to one per UDP packet transmitted to reduce network loading and packet parsing.

[ Upstream commit cc349b0771dccebf0fa9f5e1822ac444aef11448 ]
Several clocks as well as both sgmiisys phandles were added by mistake to the Ethernet bindings for MT7988. Also, the total number of clocks didn't match with the actual number of items listed.
This happened because the vendor driver which served as a reference uses a high number of syscon phandles to access various parts of the SoC which wasn't acceptable upstream. Hence several parts which have never previously been supported (such SerDes PHY and USXGMII PCS) are going to be implemented by separate drivers. As a result the device tree will look much more sane.
Quickly align the bindings with the upcoming reality of the drivers actually adding support for the remaining Ethernet-related features of the MT7988 SoC.

[ Upstream commit 4893b8b3ef8db2b182d1a1bebf6c7acf91405000 ]
Up till now the code to start HSR announce timer, which triggers sending supervisory frames, was assuming that hsr_netdev_notify() would be called at least twice for hsrX interface. This was required to have different values for old and current values of network device's operstate.
This is problematic for a case where hsrX interface is already in the operational state when hsr_netdev_notify() is called, so timer is not configured to trigger and as a result the hsrX is not sending supervisory frames to HSR ring.
This error has been discovered when hsr_ping.sh script was run. To be more specific - for the hsr1 and hsr2 the hsr_netdev_notify() was called at least twice with different IF_OPER_{LOWERDOWN|DOWN|UP} states assigned in hsr_check_carrier_and_operstate(hsr). As a result there was no issue with sending supervisory frames. However, with hsr3, the notify function was called only once with operstate set to IF_OPER_UP and timer responsible for triggering supervisory frames was not fired.
The solution is to use netif_oper_up() and netif_running() helper functions to assess if network hsrX device is up. Only then, when the timer is not already pending, it is started. Otherwise it is deactivated.

When a reset occurring, it's supposed to recover user's configuration. Currently, the port info(speed, duplex and autoneg) is stored in hclge_mac and will be scheduled updated. Consider the case that reset was happened consecutively. During the first reset, the port info is configured with a temporary value cause the PHY is reset and looking for best link config. Second reset start and use pervious configuration which is not the user's. The specific process is as follows:
+------+ +----+ +----+ | USER | | PF | | HW | +---+--+ +-+--+ +-+--+ | ethtool --reset | | +------------------->| reset command | | ethtool --reset +-------------------->| +------------------->| +---+ | +---+ | | | | |reset currently | | HW RESET | | |and wait to do | | | |<--+ | | | | send pervious cfg |<--+ | | (1000M FULL AN_ON) | | +-------------------->| | | read cfg(time task) | | | (10M HALF AN_OFF) +---+ | |<--------------------+ | cfg take effect | | reset command |<--+ | +-------------------->| | | +---+ | | send pervious cfg | | HW RESET | | (10M HALF AN_OFF) |<--+ | +-------------------->| | | read cfg(time task) | | | (10M HALF AN_OFF) +---+ | |<--------------------+ | cfg take effect | | | | | | read cfg(time task) |<--+ | | (10M HALF AN_OFF) | | |<--------------------+ | | | v v v
To avoid aboved situation, this patch introduced req_speed, req_duplex, req_autoneg to store user's configuration and it only be used after hardware reset and to recover user's configuration

During the PF initialization process, hclge_update_port_info may return an error code for some reason. At this point, the ptp initialization has been completed. To void memory leaks, the resources that are applied by ptp should be released. Therefore, when hclge_update_port_info returns an error code, hclge_ptp_uninit is called to release the corresponding resources.

According to hardware limitation, for device support modify VLAN filter state but not support bypass port VLAN filter, it should always disable the port VLAN filter. but the driver enables port VLAN filter when initializing, if there is no VLAN(except VLAN 0) id added, the driver will disable it in service task. In most time, it works fine. But there is a time window before the service task shceduled and net device being registered. So if user adds VLAN at this time, the driver will not update the VLAN filter state, and the port VLAN filter remains enabled.
To fix the problem, if support modify VLAN filter state but not support bypass port VLAN filter, set the port vlan filter to "off".

The phy is not in a useful state right after init. It will become useful, including for auxiliary function such as CEC or ARC, after the first mode is set. This is a problem on systems where the display is using another interface like DSI or CVBS.
This change refactor the init and mode change callback to power up the PHY on init and leave only what is necessary for mode changes in the related function. This is enough to fix CEC operation when HDMI display is not enabled.

[ Upstream commit 08001033121dd92b8297a5b7333636b466c30f13 ]
When no mode is set, the utility pin appears to be grounded. No signal is getting through.
This is problematic because ARC and eARC use this line and may do so even if no display mode is set.
This change enable the bandgap setting on g12 chip, which fix the problem with the utility pin. This is done by restoring init values on PHY init and disable.

From: Zhongqiu Han quic_zhonhan@quicinc.com
[ Upstream commit 02f6b0e1ec7e0e7d059dddc893645816552039da ]
The use-after-free issue occurs as follows: when the GPIO chip device file is being closed by invoking gpio_chrdev_release(), watched_lines is freed by bitmap_free(), but the unregistration of lineinfo_changed_nb notifier chain failed due to waiting write rwsem. Additionally, one of the GPIO chip's lines is also in the release process and holds the notifier chain's read rwsem. Consequently, a race condition leads to the use-after-free of watched_lines.
Here is the typical stack when issue happened:
[free] gpio_chrdev_release() --> bitmap_free(cdev->watched_lines) <-- freed --> blocking_notifier_chain_unregister() --> down_write(&nh->rwsem) <-- waiting rwsem --> __down_write_common() --> rwsem_down_write_slowpath() --> schedule_preempt_disabled() --> schedule()
[use] st54spi_gpio_dev_release() --> gpio_free() --> gpiod_free() --> gpiod_free_commit() --> gpiod_line_state_notify() --> blocking_notifier_call_chain() --> down_read(&nh->rwsem); <-- held rwsem --> notifier_call_chain() --> lineinfo_changed_notify() --> test_bit(xxxx, cdev->watched_lines) <-- use after free
The side effect of the use-after-free issue is that a GPIO line event is being generated for userspace where it shouldn't. However, since the chrdev is being closed, userspace won't have the chance to read that event anyway.
To fix the issue, call the bitmap_free() function after the unregistration of lineinfo_changed_nb notifier chain.

If a line is requested with debounce, and that results in debouncing in software, and the line is subsequently reconfigured to enable edge detection then the allocation of the kfifo to contain edge events is overlooked. This results in events being written to and read from an uninitialised kfifo. Read events are returned to userspace.
Initialise the kfifo in the case where the software debounce is already active.

This reverts drm/amdgpu: fix ftrace event amdgpu_bo_move always move on same heap. The basic problem here is that after the move the old location is simply not available any more.
Some fixes were suggested, but essentially we should call the move notification before actually moving things because only this way we have the correct order for DMA-buf and VM move notifications as well.
Also rework the statistic handling so that we don't update the eviction counter before the move.

Ensure that packet_buffer_get respects the user_length provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to signify to the user that no data were read and a larger buffer size is required. Helps prevent user space overflows.

commit 3628e0383dd349f02f882e612ab6184e4bb3dc10 upstream.
This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.
Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was:
[ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds"
and further debugging points to a possible circular locking dependency between the console_owner locking and the worker pool locking.
Reverting the commit allows Steve's VM to boot to completion again.
[ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ]

commit 808a8b9e0b87bbc72bcc1f7ddfe5d04746e7ce56 upstream.
The completion notification for the final SET_NOTIFICATION_ENABLE command during initialization can include a connector change notification. However, at the time this completion notification is processed, the ucsi struct is not ready to handle this notification. As a result the notification is ignored and the controller never sends an interrupt again.
Re-check CCI for a pending connector state change after initialization is complete. Adjust the corresponding debug message accordingly.

commit c78c3644b772e356ca452ae733a3c4de0fb11dc8 upstream.
A virtual SuperSpeed device in the FreeBSD BVCP package (https://bhyve.npulse.net/) presents an invalid ep0 maxpacket size of 256. It stopped working with Linux following a recent commit because now we check these sizes more carefully than before.
Fix this regression by using the bMaxpacketSize0 value in the device descriptor for SuperSpeed or faster devices, even if it is invalid. This is a very simple-minded change; we might want to check more carefully for values that actually make some sense (for instance, no smaller than 64).

commit fe81f354841641c7f71163b84912b25c169ed8ec upstream.
Testing ohci functionality with qemu's pci-ohci emulation often results in ohci interface stalls, resulting in hung task timeouts.
The problem is caused by lost interrupts between the emulation and the Linux kernel code. Additional interrupts raised while the ohci interrupt handler in Linux is running and before the handler clears the interrupt status are not handled. The fix for a similar problem in ehci suggests that the problem is likely caused by edge-triggered MSI interrupts. See commit 0b60557230ad ("usb: ehci: Prevent missed ehci interrupts with edge-triggered MSI") for details.
Ensure that the ohci interrupt code handles all pending interrupts before returning to solve the problem.

commit a4b46d450c49f32e9d4247b421e58083fde304ce upstream.
Testing with KASAN and syzkaller revealed a bug in port.c:disable_store(): usb_hub_to_struct_hub() can return NULL if the hub that the port belongs to is concurrently removed, but the function does not check for this possibility before dereferencing the returned value.
It turns out that the first dereference is unnecessary, since hub->intfdev is the parent of the port device, so it can be changed easily. Adding a check for hub == NULL prevents further problems.
The same bug exists in the disable_show() routine, and it can be fixed the same way.

commit ec6ce7075ef879b91a8710829016005dc8170f17 upstream.
The OS descriptors logic had the high/low byte of w_value inverted, causing the extended properties to not be accessible for interface != 0.
From the Microsoft documentation:
https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/microsoft-...
OS_Desc_CompatID.doc (w_index = 0x4):
- wValue:
High Byte = InterfaceNumber. InterfaceNumber is set to the number of the interface or function that is associated with the descriptor, typically 0x00. Because a device can have only one extended compat ID descriptor, it should ignore InterfaceNumber, regardless of the value, and simply return the descriptor.
Low Byte = 0. PageNumber is used to retrieve descriptors that are larger than 64 KB. The header section is 16 bytes, so PageNumber is set to 0 for this request.
We currently do not support >64KB compat ID descriptors, so verify that the low byte is 0.
OS_Desc_Ext_Prop.doc (w_index = 0x5):
- wValue:
High byte = InterfaceNumber. The high byte of wValue is set to the number of the interface or function that is associated with the descriptor.
Low byte = PageNumber. The low byte of wValue is used to retrieve descriptors that are larger than 64 KB. The header section is 10 bytes, so PageNumber is set to 0 for this request.
We also don't support >64KB extended properties, so verify that the low byte is 0 and use the high byte for the interface number.

commit 650ae71c80749fc7cb8858c8049f532eaec64410 upstream.
This commit fixes uvc gadget support on 32-bit platforms.
Commit 0df28607c5cb ("usb: gadget: uvc: Generalise helper functions for reuse") introduced a helper function __uvcg_iter_item_entries() to aid with parsing lists of items on configfs attributes stores. This function is a generalization of another very similar function, which used a stack-allocated temporary buffer of fixed size for each item in the list and used the sizeof() operator to check for potential buffer overruns. The new function was changed to allocate the now variably sized temp buffer on heap, but wasn't properly updated to also check for max buffer size using the computed size instead of sizeof() operator.
As a result, the maximum item size was 7 (plus null terminator) on 64-bit platforms, and 3 on 32-bit ones. While 7 is accidentally just barely enough, 3 is definitely too small for some of UVC configfs attributes. For example, dwFrameInteval, specified in 100ns units, usually has 6-digit item values, e.g. 166666 for 60fps.

commit 24729b307eefcd7c476065cd7351c1a018082c19 upstream.
FFS based applications can utilize the aio_cancel() callback to dequeue pending USB requests submitted to the UDC. There is a scenario where the FFS application issues an AIO cancel call, while the UDC is handling a soft disconnect. For a DWC3 based implementation, the callstack looks like the following:
DWC3 Gadget FFS Application dwc3_gadget_soft_disconnect() ... --> dwc3_stop_active_transfers() --> dwc3_gadget_giveback(-ESHUTDOWN) --> ffs_epfile_async_io_complete() ffs_aio_cancel() --> usb_ep_free_request() --> usb_ep_dequeue()
There is currently no locking implemented between the AIO completion handler and AIO cancel, so the issue occurs if the completion routine is running in parallel to an AIO cancel call coming from the FFS application. As the completion call frees the USB request (io_data->req) the FFS application is also referencing it for the usb_ep_dequeue() call. This can lead to accessing a stale/hanging pointer.
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently") relocated the usb_ep_free_request() into ffs_epfile_async_io_complete(). However, in order to properly implement locking to mitigate this issue, the spinlock can't be added to ffs_epfile_async_io_complete(), as usb_ep_dequeue() (if successfully dequeuing a USB request) will call the function driver's completion handler in the same context. Hence, leading into a deadlock.
Fix this issue by moving the usb_ep_free_request() back to ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req to NULL after freeing it within the ffs->eps_lock. This resolves the race condition above, as the ffs_aio_cancel() routine will not continue attempting to dequeue a request that has already been freed, or the ffs_user_copy_work() not freeing the USB request until the AIO cancel is done referencing it.
This fix depends on commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently")

commit 0aea736ddb877b93f6d2dd8cf439840d6b4970a9 upstream.
If the USB driver passes a pointer into the TRB buffer for creq, this buffer can be overwritten with the status response as soon as the event is queued. This can make the final check return USB_GADGET_DELAYED_STATUS when it shouldn't. Instead use the stored wLength.

commit 6d735722063a945de56472bdc6bfcb170fd43b86 upstream.
GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY should be cleared during initialization. Suspend during initialization can result in undefined behavior due to clock synchronization failure, which often seen as core soft reset timeout.
The programming guide recommended these bits to be cleared during initialization for DWC_usb3.0 version 1.94 and above (along with DWC_usb31 and DWC_usb32). The current check in the driver does not account if it's set by default setting from coreConsultant.
This is especially the case for DRD when switching mode to ensure the phy clocks are available to change mode. Depending on the platforms/design, some may be affected more than others. This is noted in the DWC_usb3x programming guide under the above registers.
Let's just disable them during driver load and mode switching. Restore them when the controller initialization completes.
Note that some platforms workaround this issue by disabling phy suspend through "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when they should not need to.

commit bf20c69cf3cf9c6445c4925dd9a8a6ca1b78bfdf upstream.
When a Fast Role Swap control message attempt results in a transition to ERROR_RECOVERY, the TCPC can still queue a TCPM_SOURCING_VBUS event.
If the event is queued but processed after the tcpm_reset_port() call in the PORT_RESET state, then the following occurs: 1. tcpm_reset_port() calls tcpm_init_vbus() to reset the vbus sourcing and sinking state 2. tcpm_pd_event_handler() turns VBUS on before the port is in the default state. 3. The port resolves as a sink. In the SNK_DISCOVERY state, tcpm_set_charge() cannot set vbus to charge.
Clear pd events within PORT_RESET to get rid of non-applicable events.

typec_register_partner() does not guarantee partner registration to always succeed. In the event of failure, port->partner is set to the error value or NULL. Given that port->partner validity is not checked, this results in the following crash:

commit 39815cdfc8d46ce2c72cbf2aa3d991c4bfb0024f upstream.
Unfortunately both Lenovo Legion Pro 7 16ARX8H and Legion 7i 16IAX7 got the very same PCI SSID while the hardware implementations are completely different (the former is with TI TAS2781 codec while the latter is with Cirrus CS35L41 codec). The former model got broken by the recent fix for the latter model.
For addressing the regression, check the codec SSID and apply the proper quirk for each model now.

commit 8f828aa48812ced28aa39cb3cfe55ef2444d03dd upstream.
Commit 284f17ac13fe ("mm/slub: handle bulk and single object freeing separately") splits single and bulk object freeing in two functions slab_free() and slab_free_bulk() which leads slab_free() to call slab_free_hook() directly instead of slab_free_freelist_hook().
If `init_on_free` is set, slab_free_hook() zeroes the object. Afterward, if `slub_debug=F` and `CONFIG_SLAB_FREELIST_HARDENED` are set, the do_slab_free() slowpath executes freelist consistency checks and try to decode a zeroed freepointer which leads to a "Freepointer corrupt" detection in check_object().
During bulk free, slab_free_freelist_hook() isn't affected as it always sets it objects freepointer using set_freepointer() to maintain its reconstructed freelist after `init_on_free`.
For single free, object's freepointer thus needs to be avoided when stored outside the object if `init_on_free` is set. The freepointer left as is, check_object() may later detect an invalid pointer value due to objects overflow.
To reproduce, set `slub_debug=FU init_on_free=1 log_level=7` on the command line of a kernel build with `CONFIG_SLAB_FREELIST_HARDENED=y`.

commit 63a6ce5a1a6261e4c70bad2b55c4e0de8da4762e upstream.
[BUG] When running generic/287, the following file extent items can be generated:
item 16 key (258 EXTENT_DATA 2682880) itemoff 15305 itemsize 53 generation 9 type 1 (regular) extent data disk byte 1378414592 nr 462848 extent data offset 0 nr 462848 ram 2097152 extent compression 0 (none)
Note that file extent item is not a compressed one, but its ram_bytes is way larger than its disk_num_bytes.
According to btrfs on-disk scheme, ram_bytes should match disk_num_bytes if it's not a compressed one.
[CAUSE] Since commit b73a6fd1b1ef ("btrfs: split partial dio bios before submit"), for partial dio writes, we would split the ordered extent.
However the function btrfs_split_ordered_extent() doesn't update the ram_bytes even it has already shrunk the disk_num_bytes.
Originally the function btrfs_split_ordered_extent() is only introduced for zoned devices in commit d22002fd37bd ("btrfs: zoned: split ordered extent when bio is sent"), but later commit b73a6fd1b1ef ("btrfs: split partial dio bios before submit") makes non-zoned btrfs affected.
Thankfully for un-compressed file extent, we do not really utilize the ram_bytes member, thus it won't cause any real problem.
[FIX] Also update btrfs_ordered_extent::ram_bytes inside btrfs_split_ordered_extent().

commit b5357cb268c41b4e2b7383d2759fc562f5b58c33 upstream.
[BUG] After kernel commit 86211eea8ae1 ("btrfs: qgroup: validate btrfs_qgroup_inherit parameter"), user space tool snapper will fail to create snapshot using its timeline feature.
[CAUSE] It turns out that, if using timeline snapper would unconditionally pass btrfs_qgroup_inherit parameter (assigning the new snapshot to qgroup 1/0) for snapshot creation.
In that case, since qgroup is disabled there would be no qgroup 1/0, and btrfs_qgroup_check_inherit() would return -ENOENT and fail the whole snapshot creation.
[FIX] Just skip the check if qgroup is not enabled. This is to keep the older behavior for user space tools, as if the kernel behavior changed for user space, it is a regression of kernel.
Thankfully snapper is also fixing the behavior by detecting if qgroup is running in the first place, so the effect should not be that huge.

commit e03418abde871314e1a3a550f4c8afb7b89cb273 upstream.
We previously would call btrfs_check_leaf() if we had the check integrity code enabled, which meant that we could only run the extended leaf checks if we had WRITTEN set on the header flags.
This leaves a gap in our checking, because we could end up with corruption on disk where WRITTEN isn't set on the leaf, and then the extended leaf checks don't get run which we rely on to validate all of the item pointers to make sure we don't access memory outside of the extent buffer.
However, since 732fab95abe2 ("btrfs: check-integrity: remove CONFIG_BTRFS_FS_CHECK_INTEGRITY option") we no longer call btrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only ever call it on blocks that are being written out, and thus have WRITTEN set, or that are being read in, which should have WRITTEN set.
Add checks to make sure we have WRITTEN set appropriately, and then make sure __btrfs_check_leaf() always does the item checking. This will protect us from file systems that have been corrupted and no longer have WRITTEN set on some of the blocks.
This was hit on a crafted image tweaking the WRITTEN bit and reported by KASAN as out-of-bound access in the eb accessors. The example is a dir item at the end of an eb.

commit 955a923d2809803980ff574270f81510112be9cf upstream.
Currently the code calls mas_start() followed by mas_data_end() if the maple state is MA_START, but mas_start() may return with the maple state node == NULL. This will lead to a null pointer dereference when checking information in the NULL node, which is done in mas_data_end().
Avoid setting the offset if there is no node by waiting until after the maple state is checked for an empty or single entry state.
A user could trigger the events to cause a kernel oops by unmapping all vmas to produce an empty maple tree, then mapping a vma that would cause the scenario described above.

commit cd7eb8f83fcf258f71e293f7fc52a70be8ed0128 upstream.
Currently, if an automatically freed allocation is an error pointer that will lead to a crash. An example of this is in wm831x_gpio_dbg_show().
171 char *label __free(kfree) = gpiochip_dup_line_label(chip, i); 172 if (IS_ERR(label)) { 173 dev_err(wm831x->dev, "Failed to duplicate label\n"); 174 continue; 175 }
The auto clean up function should check for error pointers as well, otherwise we're going to keep hitting issues like this.

When fallback to TCP happens early on a client socket, snd_nxt is not yet initialized and any incoming ack will copy such value into snd_una. If the mptcp worker (dumbly) tries mptcp-level re-injection after such ack, that would unconditionally trigger a send buffer cleanup using 'bad' snd_una values.
We could easily disable re-injection for fallback sockets, but such dumb behavior already helped catching a few subtle issues and a very low to zero impact in practice.
Instead address the issue always initializing snd_nxt (and write_seq, for consistency) at connect time.

commit 6963c508fd7ab66ae0b7ae3db9a62ca6267f1ae8 upstream.
The current behavior is to accept any strings as inputs, this results in an inconsistent result where an unexisting scheduler can be set:
# sysctl -w net.mptcp.scheduler=notdefault net.mptcp.scheduler = notdefault
This patch changes this behavior by checking for existing scheduler before accepting the input.

The crash is caused by calling arch_vcpu_is_preempted() for an offline CPU. To avoid this, select the cpu with cpumask_any_and_distribute() to mask __pod_cpumask with cpu_online_mask. In case no cpu is left in the pool, skip the assignment.
tj: This doesn't fully fix the bug as CPUs can still go down between picking the target CPU and the wake call. Fixing that likely requires adding cpu_online() test to either the sched or s390 arch code. However, regardless of how that is fixed, workqueue shouldn't be picking a CPU which isn't online as that would result in unpredictable and worse behavior.

The "maxim,green-led-current-microamp" property is only available for the max30105 part (it provides an extra green LED), and must be set to false for the max30102 part.
Instead, the max30100 part has been used for that, which is not supported by this binding (it has its own binding).
This error was introduced during the txt to yaml conversion.

commit 5ca29ea4e4073b3caba750efe155b1bd4c597ca9 upstream.
Bosch does not use unique BMPxxx_CHIP_ID for the different versions of the device which leads to misidentification of devices if their ID is used. Use a new value in the chip_info structure instead of the BMPxxx_CHIP_ID, in order to choose the correct regmap_bus to be used.

commit 57a1592784d622ecee0b71940c65429173996b33 upstream.
There are 2 issues with interrupt handling in the mxc4005 driver:
1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE (0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables all other interrupt sources in the INT_SRC1 register. On the MXC4005 this is not an issue because only bit 0 of the register is used. On the MXC6655 OTOH this is a problem since bit7 is used as TC (Temperature Compensation) disable bit and writing 1 to this disables Temperature Compensation which should only be done when running self-tests on the chip.
Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable the interrupts to fix this.
2. The datasheets for the MXC4005 / MXC6655 do not state what the reset value for the INT_MASK0 and INT_MASK1 registers is and since these are write only we also cannot learn this from the hw. Presumably the reset value for both is all 0, which means all interrupts disabled.
Explicitly set both registers to 0 from mxc4005_chip_init() to ensure both masks are actually set to 0.

commit 6b8cffdc4a31e4a72f75ecd1bc13fbf0dafee390 upstream.
On some designs the chip is not properly reset when powered up at boot or after a suspend/resume cycle.
Use the sw-reset feature to ensure that the chip is in a clean state after probe() / resume() and in the case of resume() restore the settings (scale, trigger-enabled).

It turned out that KMSAN instruments READ_ONCE_NOCHECK(), resulting in false positive reports, because __no_sanitize_or_inline enforced inlining.
Properly declare __no_sanitize_or_inline under __SANITIZE_MEMORY__, so that it does not __always_inline the annotated function.

commit 387f295cb2150ed164905b648d76dfcbd3621778 upstream.
This is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaround for sporadic MDI error on Meteor Lake systems"). The referenced commit used usleep_range inside the PHY access routines, which are sometimes called from an atomic context. This can lead to a kernel panic in some scenarios, such as cable disconnection and reconnection on vPro systems.
Solve this by changing the usleep_range calls back to udelay.

In the critical scenario, either the relevant skb is freed or its ownership is transferred into a frag_lists. In both cases, the cleanup code must not free it again: we need to clear the skb reference earlier.

commit 0e60f0b75884677fb9f4f2ad40d52b43451564d5 upstream.
Xtensa has two-argument MAKE_PC_FROM_RA macro to convert a0 to an actual return address because when windowed ABI is used call{,x}{4,8,12} opcodes stuff encoded window size into the top 2 bits of the register that becomes a return address in the called function. Second argument of that macro is supposed to be an address having these 2 topmost bits set correctly, but the comment suggested that that could be the stack address. However the stack doesn't have to be in the same 1GByte region as the code, especially in noMMU XIP configurations.
Fix the comment and use either _text or regs->pc as the second argument for the MAKE_PC_FROM_RA macro.

commit d85cf67a339685beae1d0aee27b7f61da95455be upstream.
The EXT_RGMII_OOB_CTRL register can be written from different contexts. It is predominantly written from the adjust_link handler which is synchronized by the phydev->lock, but can also be written from a different context when configuring the mii in bcmgenet_mii_config().
The chances of contention are quite low, but it is conceivable that adjust_link could occur during resume when WoL is enabled so use the phydev->lock synchronizer in bcmgenet_mii_config() to be sure.

commit 0d5e2a82232605b337972fb2c7d0cbc46898aca1 upstream.
The UMAC_CMD register is written from different execution contexts and has insufficient synchronization protections to prevent possible corruption. Of particular concern are the acceses from the phy_device delayed work context used by the adjust_link call and the BH context that may be used by the ndo_set_rx_mode call.
A spinlock is added to the driver to protect contended register accesses (i.e. reg_lock) and it is used to synchronize accesses to UMAC_CMD.

commit d18ca8635db2f88c17acbdf6412f26d4f6aff414 upstream.
When using davinci-mcasp as CPU DAI with simple-card, there are some conditions that cause simple-card to finish registering a sound card before davinci-mcasp finishes registering all sound components. This creates a non-working sound card from userspace with no problem indication apart from not being able to play/record audio on a PCM stream. The issue arises during simultaneous probe execution of both drivers. Specifically, the simple-card driver, awaiting a CPU DAI, proceeds as soon as davinci-mcasp registers its DAI. However, this process can lead to the client mutex lock (client_mutex in soc-core.c) being held or davinci-mcasp being preempted before PCM DMA registration on davinci-mcasp finishes. This situation occurs when the probes of both drivers run concurrently. Below is the code path for this condition. To solve the issue, defer davinci-mcasp CPU DAI registration to the last step in the audio part of it. This way, simple-card CPU DAI parsing will be deferred until all audio components are registered.
Fail Code Path:
simple-card.c: probe starts simple-card.c: simple_dai_link_of: simple_parse_node(..,cpu,..) returns EPROBE_DEFER, no CPU DAI yet davinci-mcasp.c: probe starts davinci-mcasp.c: devm_snd_soc_register_component() register CPU DAI simple-card.c: probes again, finish CPU DAI parsing and call devm_snd_soc_register_card() simple-card.c: finish probe davinci-mcasp.c: *dma_pcm_platform_register() register PCM DMA davinci-mcasp.c: probe finish

commit aacb99de1099346244d488bdf7df489a44278574 upstream.
device_get_match_data() function should not be used on the device other than the one matched to the given driver, because it always returns the match_data of the matched driver. In case of exynos-clkout driver, the original code matches the OF IDs on the PARENT device, so replacing it with of_device_get_match_data() broke the driver.
This has been already pointed once in commit 2bc5febd05ab ("clk: samsung: Revert "clk: samsung: exynos-clkout: Use of_device_get_match_data()""). To avoid further confusion, add a comment about this special case, which requires direct of_match_device() call to pass custom IDs array.
This partially reverts commit 409c39ec92a35e3708f5b5798c78eae78512cd71.

commit b914ec33b391ec766545a41f0cfc0de3e0b388d7 upstream.
The Allwinner SoC's typically have an upper and lower limit for their clocks' rates. Up until now, support for that has been implemented separately for each clock type.
Implement that functionality in the sunxi-ng's common part making use of the CCF rate liming capabilities, so that it is available for all clock types.

commit 69f16d9b789821183d342719d2ebd4a5ac7178bc upstream.
When the Allwinner A64's TCON0 searches the ideal rate for the connected panel, it may happen that it requests a rate from its parent PLL-MIPI which PLL-MIPI does not support.
This happens for example on the Olimex TERES-I laptop where TCON0 requests PLL-MIPI to change to a rate of several GHz which causes the panel to stay blank. It also happens on the pinephone where a rate of less than 500 MHz is requested which causes instabilities on some phones.
Set the minimum and maximum rate of Allwinner A64's PLL-MIPI according to the Allwinner User Manual.

We hit this when trying to initialize firmware of type NVKM_FIRMWARE_IMG_DMA because we allocate our memory with dma_alloc_coherent, and DMA allocations can't be turned back into memory pages - which a scatterlist needs in order to map them.
So, fix this by allocating the memory with vmalloc instead().

commit be4a2a81b6b90d1a47eaeaace4cc8e2cb57b96c7 upstream.
We don't get the right offset in that case. The GPU has an unused 4K area of the register BAR space into which you can remap registers. We remap the HDP flush registers into this space to allow userspace (CPU or GPU) to flush the HDP when it updates VRAM. However, on systems with >4K pages, we end up exposing PAGE_SIZE of MMIO space.

Correctly set the length of the drm_event to the size of the structure that's actually used.
The length of the drm_event was set to the parent structure instead of to the drm_vmw_event_fence which is supposed to be read. drm_read uses the length parameter to copy the event to the user space thus resuling in oob reads.

commit 6f572a80545773833f00c9a65e9242ab6fedb192 upstream.
Currently we allocate all 3 levels of radix3 page tables using nvkm_gsp_mem_ctor(), which uses dma_alloc_coherent() for allocating all of the relevant memory. This can end up failing in scenarios where the system has very high memory fragmentation, and we can't find enough contiguous memory to allocate level 2 of the page table.
Currently, this can result in runtime PM issues on systems where memory fragmentation is high - as we'll fail to allocate the page table for our suspend/resume buffer:

Luckily, we don't actually need to allocate coherent memory for the page table thanks to being able to pass the GPU a radix3 page table for suspend/resume data. So, let's rewrite nvkm_gsp_radix3_sg() to use the sg allocator for level 2. We continue using coherent allocations for lvl0 and 1, since they only take a single page.
V2: * Don't forget to actually jump to the next scatterlist when we reach the end of the scatterlist we're currently on when writing out the page table for level 2

commit c66b8356273c8d22498f88e4223af47a7bf8a23c upstream.
Intel hardware is capable of programming the Maud/Naud SDPs on its own based on real-time clocks. While doing so, it takes care of any deviations from the theoretical values. Programming the registers explicitly with static values can interfere with this logic. Therefore, let the HW decide the Maud and Naud SDPs on it's own.

commit 51c1b42a232f17743cd825be6790cb64735ff98f upstream.
We missed setting the CCS mode during resume and engine resets. Create a workaround to be added in the engine's workaround list. This workaround sets the XEHP_CCS_MODE value at every reset.
The issue can be reproduced by running:
$ clpeak --kernel-latency
Without resetting the CCS mode, we encounter a fence timeout:

commit 43b26bdd2ee5cfca80939be910d5b23a50cd7f9d upstream.
Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to backlight BDB data. Commit 700034566d68 ("drm/i915/bios: Define more BDB contents") updated the backlight BDB data accordingly. This broke the parsing of backlight BDB data in VBT for versions 236 - 238 (both inclusive) and hence the backlight controls are not responding on units with the concerned BDB version.
backlight_control information has been present in backlight BDB data from at least BDB version 191 onwards, if not before. Hence this patch extracts the backlight_control information for BDB version 191 or newer. Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236). Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251).
v2: removed checking the block size of the backlight BDB data [vsyrjala: this is completely safe thanks to commit e163cfb4c96d ("drm/i915/bios: Make copies of VBT data blocks")]

commit 892b41b16f6163e6556545835abba668fcab4eea upstream.
[Why] DSC debugfs, such as dp_dsc_clock_en_read, use aconnector->dc_link to find pipe_ctx for display. Displays connected to MST hub share the same dc_link. DSC instance is from pipe_ctx. This causes incorrect DSC instance for display connected to MST hub.
[How] Add aconnector->sink check to find pipe_ctx.

From: Volodymyr Babchuk Volodymyr_Babchuk@epam.com
commit 819fe8c96a5172dfd960e5945e8f00f8fed32953 upstream.
There are two issues with SDHC2 configuration for SA8155P-ADP, which prevent use of SDHC2 and causes issues with ethernet:
- Card Detect pin for SHDC2 on SA8155P-ADP is connected to gpio4 of PMM8155AU_1, not to SoC itself. SoC's gpio4 is used for DWMAC TX. If sdhc driver probes after dwmac driver, it reconfigures gpio4 and this breaks Ethernet MAC.
- pinctrl configuration mentions gpio96 as CD pin. It seems it was copied from some SM8150 example, because as mentioned above, correct CD pin is gpio4 on PMM8155AU_1.
This patch fixes both mentioned issues by providing correct pin handle and pinctrl configuration.

commit 65ade5653f5ab5a21635e51d0c65e95f490f5b6f upstream.
This was missed because of the function pointer indirection.
nvidia_smmu_context_fault() is also installed as a irq function, and the 'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain is embedded at a non-zero offset this causes nvidia_smmu_context_fault() to miscompute the offset. Fixup the types.

commit a26ff37e624d12e28077e5b24d2b264f62764ad6 upstream.
net_alloc_generic is called by net_alloc, which is called without any locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It is read twice, first to allocate an array, then to set s.len, which is later used to limit the bounds of the array access.
It is possible that the array is allocated and another thread is registering a new pernet ops, increments max_gen_ptrs, which is then used to set s.len with a larger than allocated length for the variable array.
Fix it by reading max_gen_ptrs only once in net_alloc_generic. If max_gen_ptrs is later incremented, it will be caught in net_assign_generic.

Following the failure observed with a delay of 250us, experiments were conducted with various delays. It was found that a delay of 350us effectively mitigated the issue.
To provide a more optimal solution while still allowing a margin for stability, the delay is being adjusted to 500us.

With 'iommu=off' on the kernel command line and x2APIC enabled by the BIOS the code which disables the x2APIC triggers an unchecked MSR access error:
RDMSR from 0x802 at rIP: 0xffffffff94079992 (native_apic_msr_read+0x12/0x50)
This is happens because default_acpi_madt_oem_check() selects an x2APIC driver before the x2APIC is disabled.
When the x2APIC is disabled because interrupt remapping cannot be enabled due to 'iommu=off' on the command line, x2apic_disable() invokes apic_set_fixmap() which in turn tries to read the APIC ID. This triggers the MSR warning because x2APIC is disabled, but the APIC driver is still x2APIC based.
Prevent that by adding an argument to apic_set_fixmap() which makes the APIC ID read out conditional and set it to false from the x2APIC disable path. That's correct as the APIC ID has already been read out during early discovery.

commit 7e6423441b36e3a03907e2df84b73c414c9c3763 upstream.
In commit 0518dbe97fe6 ("selftests/mm: fix cross compilation with LLVM") the logic to detect the machine architecture in the Makefile was changed to use ARCH, and only fallback to uname -m if ARCH is unset. However the tests of ARCH were not updated to account for the fact that ARCH is "powerpc" for powerpc builds, not "ppc64".
Fix it by changing the checks to look for "powerpc", and change the uname -m logic to convert "ppc64.*" into "powerpc".
With that fixed the following tests now build for powerpc again: * protection_keys * va_high_addr_switch * virtual_address_range * write_to_hugetlbfs

commit c88033efe9a391e72ba6b5df4b01d6e628f4e734 upstream.
Userfaultfd unregister includes a step to remove wr-protect bits from all the relevant pgtable entries, but that only covered an explicit UFFDIO_UNREGISTER ioctl, not a close() on the userfaultfd itself. Cover that too. This fixes a WARN trace.
The only user visible side effect is the user can observe leftover wr-protect bits even if the user close()ed on an userfaultfd when releasing the last reference of it. However hopefully that should be harmless, and nothing bad should happen even if so.
This change is now more important after the recent page-table-check patch we merged in mm-unstable (446dd9ad37d0 ("mm/page_table_check: support userfault wr-protect entries")), as we'll do sanity check on uffd-wp bits without vma context. So it's better if we can 100% guarantee no uffd-wp bit leftovers, to make sure each report will be valid.

commit 0f91d0795741c12cee200667648669a91b568735 upstream.
Previously, IOMMU core layer was forcing IOMMU_DOMAIN_DMA domain for untrusted device. This always took precedence over driver's def_domain_type(). Commit 59ddce4418da ("iommu: Reorganize iommu_get_default_domain_type() to respect def_domain_type()") changed the behaviour. Current code calls def_domain_type() but if it doesn't return IOMMU_DOMAIN_DMA for untrusted device it throws error. This results in IOMMU group (and potentially IOMMU itself) in undetermined state.
This patch adds untrusted check in AMD IOMMU driver code. So that it allows eGPUs behind Thunderbolt work again.
Fine tuning amd_iommu_def_domain_type() will be done later.

commit c70dce4982ce1718bf978a35f8e26160b82081f4 upstream.
make_uffd_wp_pte() was previously doing:
pte = ptep_get(ptep); ptep_modify_prot_start(ptep); pte = pte_mkuffd_wp(pte); ptep_modify_prot_commit(ptep, pte);
But if another thread accessed or dirtied the pte between the first 2 calls, this could lead to loss of that information. Since ptep_modify_prot_start() gets and clears atomically, the following is the correct pattern and prevents any possible race. Any access after the first call would see an invalid pte and cause a fault:
pte = ptep_modify_prot_start(ptep); pte = pte_mkuffd_wp(pte); ptep_modify_prot_commit(ptep, pte);

commit 2c7ad9a590d1a99ec59c7d90cef41e2b296944c4 upstream.
pagemap_scan_pmd_entry() checks if uffd-wp is set on each pte to avoid unnecessary if set. However it was previously checking with `pte_uffd_wp(ptep_get(pte))` without first confirming that the pte was present. It is only valid to call pte_uffd_wp() for present ptes. For swap ptes, pte_swp_uffd_wp() must be called because the uffd-wp bit may be kept in a different position, depending on the arch.
This was leading to test failures in the pagemap_ioctl mm selftest, when bringing up uffd-wp support on arm64 due to incorrectly interpretting the uffd-wp status of migration entries.
Let's fix this by using the correct check based on pte_present(). While we are at it, let's pass the pte to make_uffd_wp_pte() to avoid the pointless extra ptep_get() which can't be optimized out due to READ_ONCE() on many arches.

commit d5887dc6b6c054d0da3cd053afc15b7be1f45ff6 upstream.
Sandisk SN530 NVMe drives have broken MSIs. On systems without MSI-X support, all commands time out resulting in the following message:
nvme nvme0: I/O tag 12 (100c) QID 0 timeout, completion polled
These timeouts cause the boot to take an excessively-long time (over 20 minutes) while the initial command queue is flushed.
Address this by adding a quirk for drives with buggy MSIs. The lspci output for this device (recorded on a system with MSI-X support) is:

regulator_get() may sometimes be called more than once for the same consumer device, something which before commit dbe954d8f163 ("regulator: core: Avoid debugfs: Directory ... already present! error") resulted in errors being logged.
A couple of recent commits broke the handling of such cases so that attributes are now erroneously created in the debugfs root directory the second time a regulator is requested and the log is filled with errors like:
debugfs: File 'uA_load' in directory '/' already present! debugfs: File 'min_uV' in directory '/' already present! debugfs: File 'max_uV' in directory '/' already present! debugfs: File 'constraint_flags' in directory '/' already present!
on any further calls.

Before ORing the new clock rate with the control register value read from the hardware, the existing clock rate needs to be masked off as otherwise the existing value will interfere with the new one.

ΕΛΕΝΗ reported that ksmbd binds to the IPV6 wildcard (::) by default for ipv4 and ipv6 binding. So IPV4 connections are successful only when the Linux system parameter bindv6only is set to 0 [default value]. If this parameter is set to 1, then the ipv6 wildcard only represents any IPV6 address. Samba creates different sockets for ipv4 and ipv6 by default. This patch off sk_ipv6only to support IPV4/IPV6 connections without creating two sockets.

if ksmbd sends multiple notifications for a file, cifs increments the reference count of the file but it does not decrement the count by the failure of queue_work. So even if the file is closed, cifs does not send a SMB2_CLOSE request.

cifs.ko doesn't set parent lease key and epoch in create context v2 lease. ksmbd suppose that parent lease and epoch are vaild if data length is v2 lease context size and handle directory lease using this values. ksmbd should hanle it as v1 lease not v2 lease if parent lease key and epoch are not set in create context v2 lease.

commit baa23a8d4360d981a49913841a726edede5cdd54 upstream.
There's an inconsistency with the way permissions are handled in tracefs. Because the permissions are generated when accessed, they default to the root inode's permission if they were never set by the user. If the user sets the permissions, then a flag is set and the permissions are saved via the inode (for tracefs files) or an internal attribute field (for eventfs).
But if a remount happens that specify the permissions, all the files that were not changed by the user gets updated, but the ones that were are not. If the user were to remount the file system with a given permission, then all files and directories within that file system should be updated.
This can cause security issues if a file's permission was updated but the admin forgot about it. They could incorrectly think that remounting with permissions set would update all files, but miss some.
For example:
# cd /sys/kernel/tracing # chgrp 1002 current_tracer # ls -l [..] -rw-r----- 1 root root 0 May 1 21:25 buffer_size_kb -rw-r----- 1 root root 0 May 1 21:25 buffer_subbuf_size_kb -r--r----- 1 root root 0 May 1 21:25 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 21:25 current_tracer -rw-r----- 1 root root 0 May 1 21:25 dynamic_events -r--r----- 1 root root 0 May 1 21:25 dyn_ftrace_total_info -r--r----- 1 root root 0 May 1 21:25 enabled_functions
Where current_tracer now has group "lkp".
# mount -o remount,gid=1001 . # ls -l -rw-r----- 1 root tracing 0 May 1 21:25 buffer_size_kb -rw-r----- 1 root tracing 0 May 1 21:25 buffer_subbuf_size_kb -r--r----- 1 root tracing 0 May 1 21:25 buffer_total_size_kb -rw-r----- 1 root lkp 0 May 1 21:25 current_tracer -rw-r----- 1 root tracing 0 May 1 21:25 dynamic_events -r--r----- 1 root tracing 0 May 1 21:25 dyn_ftrace_total_info -r--r----- 1 root tracing 0 May 1 21:25 enabled_functions
Everything changed but the "current_tracer".
Add a new link list that keeps track of all the tracefs_inodes which has the permission flags that tell if the file/dir should use the root inode's permission or not. Then on remount, clear all the flags so that the default behavior of using the root inode's permission is done for all files and directories.

commit 6599bd5517be66c8344f869f3ca3a91bc10f2b9e upstream.
If the instances directory's permissions were never change, then have it and its children use the mount point permissions as the default.
Currently, the permissions of instance directories are determined by the instance directory's permissions itself. But if the tracefs file system is remounted and changes the permissions, the instance directory and its children should use the new permission.
But because both the instance directory and its children use the instance directory's inode for permissions, it misses the update.
To demonstrate this:
# cd /sys/kernel/tracing/ # mkdir instances/foo # ls -ld instances/foo drwxr-x--- 5 root root 0 May 1 19:07 instances/foo # ls -ld instances drwxr-x--- 3 root root 0 May 1 18:57 instances # ls -ld current_tracer -rw-r----- 1 root root 0 May 1 18:57 current_tracer
# mount -o remount,gid=1002 . # ls -ld instances drwxr-x--- 3 root root 0 May 1 18:57 instances # ls -ld instances/foo/ drwxr-x--- 5 root root 0 May 1 19:07 instances/foo/ # ls -ld current_tracer -rw-r----- 1 root lkp 0 May 1 18:57 current_tracer
Notice that changing the group id to that of "lkp" did not affect the instances directory nor its children. It should have been:
# ls -ld current_tracer -rw-r----- 1 root root 0 May 1 19:19 current_tracer # ls -ld instances/foo/ drwxr-x--- 5 root root 0 May 1 19:25 instances/foo/ # ls -ld instances drwxr-x--- 3 root root 0 May 1 19:19 instances
# mount -o remount,gid=1002 . # ls -ld current_tracer -rw-r----- 1 root lkp 0 May 1 19:19 current_tracer # ls -ld instances drwxr-x--- 3 root lkp 0 May 1 19:19 instances # ls -ld instances/foo/ drwxr-x--- 5 root lkp 0 May 1 19:25 instances/foo/
Where all files were updated by the remount gid update.

commit d53891d348ac3eceaf48f4732a1f4f5c0e0a55ce upstream.
The toplevel events directory is really no different than the events directory of instances. Having the two be different caused inconsistencies and made it harder to fix the permissions bugs.
Make all events directories act the same.

commit 22e61e15af731dbe46704c775d2335e56fcef4e9 upstream.
Treat the events directory the same as other directories when it comes to permissions. The events directory was considered different because it's dentry is persistent, whereas the other directory dentries are created when accessed. But the way tracefs now does its ownership by using the root dentry's permissions as the default permissions, the events directory can get out of sync when a remount is performed setting the group and user permissions.
Remove the special case for the events directory on setting the attributes. This allows the updates caused by remount to work properly as well as simplifies the code.

commit 32868e126c78876a8a5ddfcb6ac8cb2fffcf4d27 upstream.
Qualcomm Bluetooth controllers may not have been provisioned with a valid device address and instead end up using the default address 00:00:00:00:5a:ad.
This was previously believed to be due to lack of persistent storage for the address but it may also be due to integrators opting to not use the on-chip OTP memory and instead store the address elsewhere (e.g. in storage managed by secure world firmware).
According to Qualcomm, at least WCN6750, WCN6855 and WCN7850 have on-chip OTP storage for the address.
As the device type alone cannot be used to determine when the address is valid, instead read back the address during setup() and only set the HCI_QUIRK_USE_BDADDR_PROPERTY flag when needed.
This specifically makes sure that controllers that have been provisioned with an address do not start as unconfigured.

commit 66c39332d02d65e311ec89b0051130bfcd00c9ac upstream.
Qualcomm Bluetooth controllers may not have been provisioned with a valid device address and instead end up using the default address 00:00:00:00:5a:ad.
This address is now used to determine if a controller has a valid address or if one needs to be provided through devicetree or by user space before the controller can be used.
It turns out that the WCN3991 controllers used in Chromium Trogdor machines use a different default address, 39:98:00:00:5a:ad, which also needs to be marked as invalid so that the correct address is fetched from the devicetree.
Qualcomm has unfortunately not yet provided any answers as to whether the 39:98 encodes a hardware id and if there are other variants of the default address that needs to be handled by the driver.
For now, add the Trogdor WCN3991 default address to the device address check to avoid having these controllers start with the default address instead of their assigned addresses.

commit a112d3c72a227f2edbb6d8094472cc6e503e52af upstream.
The NVM configuration files used by WCN3988 and WCN3990/1/8 have two sets of configuration tags that are enclosed by a type-length header of type four which the current parser fails to account for.
Instead the driver happily parses random data as if it were valid tags, something which can lead to the configuration data being corrupted if it ever encounters the words 0x0011 or 0x001b.
As is clear from commit b63882549b2b ("Bluetooth: btqca: Fix the NVM baudrate tag offcet for wcn3991") the intention has always been to process the configuration data also for WCN3991 and WCN3998 which encodes the baud rate at a different offset.
Fix the parser so that it can handle the WCN3xxx configuration files, which has an enclosing type-length header of type four and two sets of TLV tags enclosed by a type-length header of type two and three, respectively.
Note that only the first set, which contains the tags the driver is currently looking for, will be parsed for now.
With the parser fixed, the software in-band sleep bit will now be set for WCN3991 and WCN3998 (as it is for later controllers) and the default baud rate 3200000 may be updated by the driver also for WCN3xxx controllers.
Notably the deep-sleep feature bit is already set by default in all configuration files in linux-firmware.

commit dd336649ba89789c845618dcbc09867010aec673 upstream.
The default device address apparently comes from the NVM configuration file and can differ quite a bit between controllers.
Store the default address when parsing the configuration file and use it to determine whether the controller has been provisioned with an address.
This makes sure that devices without a unique address start as unconfigured unless a valid address has been provided in the devicetree.

commit 40d442f969fb1e871da6fca73d3f8aef1f888558 upstream.
A recent commit fixed the code that parses the firmware files before downloading them to the controller but introduced a memory leak in case the sanity checks ever fail.
Make sure to free the firmware buffer before returning on errors.
