[ Upstream commit 55a387ebb9219cbe4edfa8ba9996ccb0e7ad4932 ]

The phy-rcar-gen3-usb2 driver exposes four individual PHYs that are requested and configured by PHY users. The struct phy_ops APIs access the same set of registers to configure all PHYs. Additionally, PHY settings can be modified through sysfs or an IRQ handler. While some struct phy_ops APIs are protected by a driver-wide mutex, others rely on individual PHY-specific mutexes.

This approach can lead to various issues, including: 1/ the IRQ handler may interrupt PHY settings in progress, racing with hardware configuration protected by a mutex lock 2/ due to msleep(20) in rcar_gen3_init_otg(), while a configuration thread suspends to wait for the delay, another thread may try to configure another PHY (with phy_init() + phy_power_on()); re-running the phy_init() goes to the exact same configuration code, re-running the same hardware configuration on the same set of registers (and bits) which might impact the result of the msleep for the 1st configuring thread 3/ sysfs can configure the hardware (though role_store()) and it can still race with the phy_init()/phy_power_on() APIs calling into the drivers struct phy_ops

To address these issues, add a spinlock to protect hardware register access and driver private data structures (e.g., calls to rcar_gen3_is_any_rphy_initialized()). Checking driver-specific data remains necessary as all PHY instances share common settings. With this change, the existing mutex protection is removed and the cleanup.h helpers are used.

While at it, to keep the code simpler, do not skip regulator_enable()/regulator_disable() APIs in rcar_gen3_phy_usb2_power_on()/rcar_gen3_phy_usb2_power_off() as the regulators enable/disable operations are reference counted anyway.

[ Upstream commit ea7789c1541084a3dae65ffd36778348dd98f61b ]

Instead of mapping and unmapping the completion queues memory to the host PCI address space whenever nvmet_pci_epf_cq_work() is called, map a completion queue to the host PCI address space when the completion queue is created with nvmet_pci_epf_create_cq() and unmap it when the completion queue is deleted with nvmet_pci_epf_delete_cq().

This removes the completion queue mapping/unmapping from nvmet_pci_epf_cq_work() and significantly increases performance. For a single job 4K random read QD=1 workload, the IOPS is increased from 23 KIOPS to 25 KIOPS. Some significant throughput increasde for high queue depth and large IOs workloads can also be seen.

Since the functions nvmet_pci_epf_map_queue() and nvmet_pci_epf_unmap_queue() are called respectively only from nvmet_pci_epf_create_cq() and nvmet_pci_epf_delete_cq(), these functions are removed and open-coded in their respective call sites.

All platforms since Snapdragon 8 Gen1 (SM8450) require using 4-byte reads to access QFPROM data. While older platforms were more than happy with 1-byte reads, change the qfprom driver to use 4-byte reads for all the platforms. Specify stride and word size of 4 bytes. To retain compatibility with the existing DT and to simplify porting data from vendor kernels, use fixup_dt_cell_info in order to bump alignment requirements.

In the debug and resolution of an issue involving forced use of bounce buffers, 7170130e4c72 ("x86/mm/init: Handle the special case of device private pages in add_pages(), to not increase max_pfn and trigger dma_addressing_limited() bounce buffers"). It would have been easier to debug the issue if dma_addressing_limited() had debug information about the device not being able to address all of memory and thus forcing all accesses through a bounce buffer. Please see[2]

Implement dev_dbg to debug the potential use of bounce buffers when we hit the condition. When swiotlb is used, dma_addressing_limited() is used to determine the size of maximum dma buffer size in dma_direct_max_mapping_size(). The debug prints could be triggered in that check as well (when enabled).

On IMA policy update, if a measure rule exists in the policy, IMA_MEASURE is set for ima_policy_flags which makes the violation_check variable always true. Coupled with a no-action on MAY_READ for a FILE_CHECK call, we're always taking the inode_lock().

This becomes a performance problem for extremely heavy read-only workloads. Therefore, prevent this only in the case there's no action to be taken.

[Why]

Urgent latency adjustment was disabled on DCN35 due to issues with P0 enablement on some platforms. Without urgent latency, underflows occur when doing certain high timing configurations. After testing, we found that reenabling urgent latency didn't reintroduce p0 support on multiple platforms.

[How]

renable urgent latency on DCN35 and setting it to 3000 Mhz.

It happens because disconnect has been disabled for TLS [1], and it renders the test case invalid.

Removing all the test code creates a conflict between bpf and bpf-next, so for now only remove the offending assert [2].

The test will be removed later on bpf-next.

[ Upstream commit a26fe287eed112b4e21e854f173c8918a6a8596d ]

The scripts/kconfig/merge_config.sh script requires an existing $INITFILE (or the $1 argument) as a base file for merging Kconfig fragments. However, an empty $INITFILE can serve as an initial starting point, later referenced by the KCONFIG_ALLCONFIG Makefile variable if -m is not used. This variable can point to any configuration file containing preset config symbols (the merged output) as stated in Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will contain just the merge output requiring the user to run make (i.e. KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make olddefconfig).

Instead of failing when `$INITFILE` is missing, create an empty file and use it as the starting point for merges.

An erroneous message is written to the kernel log when either of the following actions are taken by a user:

2. Reserve an adapter or domain for the host device driver via the AP bus driver's sysfs apmask or aqmask attribute that would result in providing host access to an AP queue that is in use by a vfio_ap mediated device. Reserving a queue for a host driver that is in use by an mdev is not allowed.

In both cases, the assignment will return an error; however, a message like the following is written to the kernel log:

vfio_ap_mdev e1839397-51a0-4e3c-91e0-c3b9c3d3047d: Userspace may not re-assign queue 00.0028 already assigned to \ e1839397-51a0-4e3c-91e0-c3b9c3d3047d

Notice the mdev reporting the error is the same as the mdev identified in the message as the one to which the queue is being assigned. It is perfectly okay to assign a queue to an mdev to which it is already assigned; the assignment is simply ignored by the vfio_ap device driver.

This patch logs more descriptive and accurate messages for both 1 and 2 above to the kernel log:

Example for 1: vfio_ap_mdev 0fe903a0-a323-44db-9daf-134c68627d61: Userspace may not assign queue 00.0033 to mdev: already assigned to \ 62177883-f1bb-47f0-914d-32a22e3a8804

Example for 2: vfio_ap_mdev 62177883-f1bb-47f0-914d-32a22e3a8804: Can not reserve queue 00.0033 for host driver: in use by mdev

[ Upstream commit 4236ac9fe5b8b42756070d4abfb76fed718e87c2 ]

Old SMB1 servers without CAP_NT_SMBS do not support CIFS_open() function and instead SMBLegacyOpen() needs to be used. This logic is already handled in cifs_open_file() function, which is server->ops->open callback function.

So for querying and creating MF symlinks use open callback function instead of CIFS_open() function directly.

This change fixes querying and creating new MF symlinks on Windows 98. Currently cifs_query_mf_symlink() is not able to detect MF symlink and cifs_create_mf_symlink() is failing with EIO error.

[ Upstream commit e94e882a6d69525c07589222cf3a6ff57ad12b5b ]

SMB negotiate retry functionality in cifs_negotiate() is currently broken and does not work when doing socket reconnect. Caller of this function, which is cifs_negotiate_protocol() requires that tcpStatus after successful execution of negotiate callback stay in CifsInNegotiate. But if the CIFSSMBNegotiate() called from cifs_negotiate() fails due to connection issues then tcpStatus is changed as so repeated CIFSSMBNegotiate() call does not help.

Fix this problem by moving retrying code from negotiate callback (which is either cifs_negotiate() or smb2_negotiate()) to cifs_negotiate_protocol() which is caller of those callbacks. This allows to properly handle and implement correct transistions between tcpStatus states as function cifs_negotiate_protocol() already handles it.

With this change, cifs_negotiate_protocol() now handles also -EAGAIN error set by the RFC1002_NEGATIVE_SESSION_RESPONSE processing after reconnecting with NetBIOS session.

Instead of saving off the text and data pointers and using them to compare with the current boot's text and data pointers, just save off the KASLR offset. Then that can be used to figure out how to read the previous boots buffer.

The last_boot_info will now show this offset, but only if it is for a previous boot:

~# cat instances/boot_mapped/last_boot_info 39000000 [kernel]

~# echo function > instances/boot_mapped/current_tracer ~# cat instances/boot_mapped/last_boot_info # Current

If the KASLR offset saved is for the current boot, the last_boot_info will show the value of "current".

[ Upstream commit f06777cf2bbc21dd8c71d6e3906934e56b4e18e4 ]

Intel Over-Clocking Watchdogs are described in ACPI tables by both the generic PNP0C02 _CID and their ACPI _HID. The presence of the _CID then causes the PNP scan handler to attach to the watchdog, preventing the actual watchdog driver from binding. Address this by adding the ACPI _HIDs to the list of non-PNP devices, so that the PNP scan handler is bypassed.

Note that these watchdogs can be described by multiple _HIDs for what seems to be identical hardware. This commit is not a complete list of all the possible watchdog ACPI _HIDs.

The Platform Communication Channel (PCC) mailbox driver currently uses ioremap() to map channel shared memory regions. However it is preferred to use acpi_os_ioremap(), which is mapping function specific to EFI/ACPI defined memory regions. It ensures that the correct memory attributes are applied when mapping ACPI-provided regions.

While at it, also add checks for handling any errors with the mapping.

NOMMU kernels currently cannot access memory below the kernel link address. Remove this restriction by setting PAGE_OFFSET to the actual start of RAM, as determined from the devicetree. The kernel link address must be a constant, so keep using CONFIG_PAGE_OFFSET for that purpose.

[ Upstream commit 892c788d73fe4a94337ed092cb998c49fa8ecaf4 ]

The erase colour calculation for fbcon clearing should use get_color instead of attr_col_ec, like everything else. The latter is similar but is not correct. For example it's missing the depth dependent remapping and doesn't care about blanking.

The problem can be reproduced by setting up the background colour to grey (vt.color=0x70) and having an fbcon console set to 2bpp (4 shades of gray). Now the background attribute should be 1 (dark gray) on the console.

If the screen is scrolled when pressing enter in a shell prompt at the bottom line then the new line is cleared using colour 7 instead of 1. That's not something fillrect likes (at 2bbp it expect 0-3) so the result is interesting.

This patch switches to get_color with vc_video_erase_char to determine the erase colour from attr_col_ec. That makes the latter function redundant as no other users were left.

Use correct erase colour for clearing in fbcon

Windows SMB servers (including SMB2+) which are working over RFC1001 require that Netbios server name specified in RFC1001 Session Request packet is same as the UNC host name. Netbios server name can be already specified manually via -o servern= option.

[ Upstream commit 781802aa5a5950f99899f13ff9d760f5db81d36d ]

Function ip_rfc1001_connect() which establish NetBIOS session for SMB connections, currently uses smb_send() function for sending NetBIOS Session Request packet. This function expects that the passed buffer is SMB packet and for SMB2+ connections it mangles packet header, which breaks prepared NetBIOS Session Request packet. Result is that this function send garbage packet for SMB2+ connection, which SMB2+ server cannot parse. That function is not mangling packets for SMB1 connections, so it somehow works for SMB1.

Fix this problem and instead of smb_send(), use smb_send_kvec() function which does not mangle prepared packet, this function send them as is. Just API of this function takes struct msghdr (kvec) instead of packet buffer.

[MS-SMB2] specification allows SMB2 protocol to use NetBIOS as a transport protocol. NetBIOS can be used over TCP via port 139. So this is a valid configuration, just not so common. And even recent Windows versions (e.g. Windows Server 2022) still supports this configuration: SMB over TCP port 139, including for modern SMB2 and SMB3 dialects.

This change fixes SMB2 and SMB3 connections over TCP port 139 which requires establishing of NetBIOS session. Tested that this change fixes establishing of SMB2 and SMB3 connections with Windows Server 2022.

Using Clement's new validation callbacks, support checking that dependencies have been satisfied for the vector extensions. From the kernel's perfective, it's not required to differentiate between the conditions for all the various vector subsets - it's the firmware's job to not report impossible combinations. Instead, the kernel only has to check that the correct config options are enabled and to enforce its requirement of the d extension being present for FPU support.

Since vector will now be disabled proactively, there's no need to clear the bit in elf_hwcap in riscv_fill_hwcap() any longer.

[ Upstream commit 61c39d8c83e2077f33e0a2c8980a76a7f323f0ce ]

Since:

0c1d7a2c2d32 ("lockdep: Remove softirq accounting on PREEMPT_RT.")

the wait context test for mutex usage within "in softirq context" fails as it references @softirq_context:

| wait context tests | -------------------------------------------------------------------------- | rcu | raw | spin |mutex | -------------------------------------------------------------------------- in hardirq context: ok | ok | ok | ok | in hardirq context (not threaded): ok | ok | ok | ok | in softirq context: ok | ok | ok |FAILED|

As a fix, add lockdep map for BH disabled section. This fixes the issue by letting us catch cases when local_bh_disable() gets called with preemption disabled where local_lock doesn't get acquired. In the case of "in softirq context" selftest, local_bh_disable() was being called with preemption disable as it's early in the boot.

[ boqun: Move the lockdep annotations into __local_bh_*() to avoid false positives because of unpaired local_bh_disable() reported by Borislav Petkov and Peter Zijlstra, and make bh_lock_map only exist for PREEMPT_RT. ]

[ mingo: Restored authorship and improved the bh_lock_map definition. ]

In the critical submission path memory allocations can't wait for reclaim since that can potentially wait for submissions to finish.

Finally clean that up and mark most memory allocations in the critical path with GFP_NOWAIT. The only exception left is the dma_fence_array() used when no VMID is available, but that will be cleaned up later on.

[ Upstream commit 6c4d5aadf5df31ea0ac025980670eee9beaf466b ]

MSI remapping bypass (directly configuring MSI entries for devices on the VMD bus) won't work under Xen, as Xen is not aware of devices in such bus, and hence cannot configure the entries using the pIRQ interface in the PV case, and in the PVH case traps won't be setup for MSI entries for such devices.

Until Xen is aware of devices in the VMD bus prevent the VMD_FEAT_CAN_BYPASS_MSI_REMAP capability from being used when running as any kind of Xen guest.

The MSI remapping bypass is an optional feature of VMD bridges, and hence when running under Xen it will be masked and devices will be forced to redirect its interrupts from the VMD bridge. That mode of operation must always be supported by VMD bridges and works when Xen is not aware of devices behind the VMD bridge.

A user complained that a message such as:

EXT4-fs (nvme0n1p3): re-mounted UUID ro. Quota mode: none.

implied that the file system was previously mounted read/write and was now remounted read-only, when it could have been some other mount state that had changed by the "mount -o remount" operation. Fix this by only logging "ro"or "r/w" when it has changed.

[ Upstream commit 0fb482728ba1ee2130eaa461bf551f014447997c ]

This is another attempt trying to make pidfd polling for multi-threaded exec and premature thread-group leader exit consistent.

A quick recap of these two cases:

(1) During a multi-threaded exec by a subthread, i.e., non-thread-group leader thread, all other threads in the thread-group including the thread-group leader are killed and the struct pid of the thread-group leader will be taken over by the subthread that called exec. IOW, two tasks change their TIDs.

(2) A premature thread-group leader exit means that the thread-group leader exited before all of the other subthreads in the thread-group have exited.

Both cases lead to inconsistencies for pidfd polling with PIDFD_THREAD. Any caller that holds a PIDFD_THREAD pidfd to the current thread-group leader may or may not see an exit notification on the file descriptor depending on when poll is performed. If the poll is performed before the exec of the subthread has concluded an exit notification is generated for the old thread-group leader. If the poll is performed after the exec of the subthread has concluded no exit notification is generated for the old thread-group leader.

The correct behavior would be to simply not generate an exit notification on the struct pid of a subhthread exec because the struct pid is taken over by the subthread and thus remains alive.

But this is difficult to handle because a thread-group may exit prematurely as mentioned in (2). In that case an exit notification is reliably generated but the subthreads may continue to run for an indeterminate amount of time and thus also may exec at some point.

So far there was no way to distinguish between (1) and (2) internally. This tiny series tries to address this problem by discarding PIDFD_THREAD notification on premature thread-group leader exit.

If that works correctly then no exit notifications are generated for a PIDFD_THREAD pidfd for a thread-group leader until all subthreads have been reaped. If a subthread should exec aftewards no exit notification will be generated until that task exits or it creates subthreads and repeates the cycle.

The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be lowered to less than 0.5V for a minimum of 1 ms when powering off a card. Increase wait to 15 ms so that voltage has time to drain down to 0.5V and cards can power off correctly. Issues with voltage drain time were only observed on Apollo Lake and Bay Trail host controllers so this fix is limited to those devices.

[ Upstream commit 0efc297a3c4974dbd609ee36fc6345720b6ca735 ]

cgroup_rstat_flush_locked() grabs the irq safe cgroup_rstat_lock while iterating all possible cpus. It only drops the lock if there is scheduler or spin lock contention. If neither, then interrupts can be disabled for a long time. On large machines this can disable interrupts for a long enough time to drop network packets. On 400+ CPU machines I've seen interrupt disabled for over 40 msec.

Prevent rstat from disabling interrupts while processing all possible cpus. Instead drop and reacquire cgroup_rstat_lock for each cpu. This approach was previously discussed in https://lore.kernel.org/lkml/ZBz%2FV5a7%2F6PZeM7S@slm.duckdns.org/, though this was in the context of an non-irq rstat spin lock.

Benchmark this change with: 1) a single stat_reader process with 400 threads, each reading a test memcg's memory.stat repeatedly for 10 seconds. 2) 400 memory hog processes running in the test memcg and repeatedly charging memory until oom killed. Then they repeat charging and oom killing.

v6.14-rc6 with CONFIG_IRQSOFF_TRACER with stat_reader and hogs, finds interrupts are disabled by rstat for 45341 usec: # => started at: _raw_spin_lock_irq # => ended at: cgroup_rstat_flush # # # _------=> CPU# # / _-----=> irqs-off/BH-disabled # | / _----=> need-resched # || / _---=> hardirq/softirq # ||| / _--=> preempt-depth # |||| / _-=> migrate-disable # ||||| / delay # cmd pid |||||| time | caller # \ / |||||| \ | / stat_rea-96532 52d.... 0us*: _raw_spin_lock_irq stat_rea-96532 52d.... 45342us : cgroup_rstat_flush stat_rea-96532 52d.... 45342us : tracer_hardirqs_on <-cgroup_rstat_flush stat_rea-96532 52d.... 45343us : <stack trace> => memcg1_stat_format => memory_stat_format => memory_stat_show => seq_read_iter => vfs_read => ksys_read => do_syscall_64 => entry_SYSCALL_64_after_hwframe

With this patch the CONFIG_IRQSOFF_TRACER doesn't find rstat to be the longest holder. The longest irqs-off holder has irqs disabled for 4142 usec, a huge reduction from previous 45341 usec rstat finding.

Running stat_reader memory.stat reader for 10 seconds: - without memory hogs: 9.84M accesses => 12.7M accesses - with memory hogs: 9.46M accesses => 11.1M accesses The throughput of memory.stat access improves.

The mode of memory.stat access latency after grouping by of 2 buckets: - without memory hogs: 64 usec => 16 usec - with memory hogs: 64 usec => 8 usec The memory.stat latency improves.

[ Upstream commit 0c5a89ceddc1728a40cb3313948401dd70e3c649 ]

The interrupt status polling is unreliable, which can cause status events to get lost. On all newer chips, txs-timeout is an indication that the packet was either never sent, or never acked. Fixes issues with inactivity polling.

[ Upstream commit 24a295e4ef1ca8e97d8b7015e1887b6e83e1c8be ]

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel.

This can be very confusing when switching between userspace and kernelspace coding, or when dealing with UAPI headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now.

This is mostly a mechanical patch (done with a simple "sed -i" statement), with some manual tweaks in <asm/frame.h>, <asm/hw_irq.h> and <asm/setup.h> that mentioned this macro in comments with some missing underscores.
