commit 07edfece8bcb0580a1828d939e6f8d91a8603eb2 upstream.
At CPU-hotplug time, unbind_worker() may preempt a worker while it is waking up. In that case the following scenario can happen:
unbind_workers() wq_worker_running() -------------- ------------------- if (!(worker->flags & WORKER_NOT_RUNNING)) //PREEMPTED by unbind_workers worker->flags |= WORKER_UNBOUND; [...] atomic_set(&pool->nr_running, 0); //resume to worker atomic_inc(&worker->pool->nr_running);
After unbind_worker() resets pool->nr_running, the value is expected to remain 0 until the pool ever gets rebound in case cpu_up() is called on the target CPU in the future. But here the race leaves pool->nr_running with a value of 1, triggering the following warning when the worker goes idle:

Also due to this incorrect "nr_running == 1", further queued work may end up not being served, because no worker is awaken at work insert time. This raises rcutorture writer stalls for example.
Fix this with disabling preemption in the right place in wq_worker_running().
It's worth noting that if the worker migrates and runs concurrently with unbind_workers(), it is guaranteed to see the WORKER_UNBOUND flag update due to set_cpus_allowed_ptr() acquiring/releasing rq->lock.

Also due to this incorrect "nr_running == -1", all sorts of hazards can happen, starting with queued works being ignored because no workers are awaken at insert_work() time.
Fix this with checking again the worker flags while pool->lock is locked.

commit 9d36de31130542fc060f7cd17e72db670202c682 upstream.
When the driver is unloaded or when the system goes into standby mode, DeInitLed871x is called to stop the led layer. In this case, we stop the blinking worker but we do not switch the led off explicitly. On my system, I can go into standby mode with the LED enabled.
Add a call to SwLedOff to fix this.

[ no upstream commit given implicitly fixed through the larger refactoring in c25b2ae136039ffa820c26138ed4a5e5f3ab3841 ]
While auditing some other code, I noticed missing checks inside the pointer arithmetic simulation, more specifically, adjust_ptr_min_max_vals(). Several *_OR_NULL types are not rejected whereas they are _required_ to be rejected given the expectation is that they get promoted into a 'real' pointer type for the success case, that is, after an explicit != NULL check.
One case which stands out and is accessible from unprivileged (iff enabled given disabled by default) is BPF ring buffer. From crafting a PoC, the NULL check can be bypassed through an offset, and its id marking will then lead to promotion of mem_or_null to a mem type.
bpf_ringbuf_reserve() helper can trigger this case through passing of reserved flags, for example.

All three commits, that is b121b341e598 ("bpf: Add PTR_TO_BTF_ID_OR_NULL support"), 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it"), and the afbf21dce668 ("bpf: Support readonly/readwrite buffers in verifier") suffer the same cause and their *_OR_NULL type pendants must be rejected in adjust_ptr_min_max_vals().
Make the test more robust by reusing reg_type_may_be_null() helper such that we catch all *_OR_NULL types we have today and in future.
Note that pointer arithmetic on PTR_TO_BTF_ID, PTR_TO_RDONLY_BUF, and PTR_TO_RDWR_BUF is generally allowed.

commit 95655456e7cee858a23793f67025765b4c4c227b upstream.
This patch fixes the broken LED quirk for Intel legacy ROM devices. To fix the LED issue that doesn't turn off immediately, the host sends the SW RFKILL command while shutting down the interface and it puts the devices in SW RFKILL state.
Once the device is in SW RFKILL state, it can only accept HCI_Reset to exit from the SW RFKILL state. This patch checks the quirk for broken LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version command.
The affected legacy ROM devices are - 8087:07dc - 8087:0a2a - 8087:0aa7

commit b5e6fa7a12572c82f1e7f2f51fbb02a322291291 upstream.
Add the missing bulk-out endpoint sanity check to probe() to avoid division by zero in bfusb_send_frame() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing).
Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).

commit 0f663729bb4afc92a9986b66131ebd5b8a9254d1 upstream.
Bugzilla #213839 reports a 7-port hub that doesn't work properly when devices are plugged into some of the ports; the kernel goes into an unending disconnect/reinitialize loop as shown in the bug report.
This "7-port hub" comprises two four-port hubs with one plugged into the other; the failures occur when a device is plugged into one of the downstream hub's ports. (These hubs have other problems too. For example, they bill themselves as USB-2.0 compliant but they only run at full speed.)
It turns out that the failures are caused by bugs in both the kernel and the hub. The hub's bug is that it reports a different bmAttributes value in its configuration descriptor following a remote wakeup (0xe0 before, 0xc0 after -- the wakeup-support bit has changed).
The kernel's bug is inside the hub driver's resume handler. When hub_activate() sees that one of the hub's downstream ports got a wakeup request from a child device, it notes this fact by setting the corresponding bit in the hub->change_bits variable. But this variable is meant for connection changes, not wakeup events; setting it causes the driver to believe the downstream port has been disconnected and then connected again (in addition to having received a wakeup request).
Because of this, the hub driver then tries to check whether the device currently plugged into the downstream port is the same as the device that had been attached there before. Normally this check succeeds and wakeup handling continues with no harm done (which is why the bug remained undetected until now). But with these dodgy hubs, the check fails because the config descriptor has changed. This causes the hub driver to reinitialize the child device, leading to the disconnect/reinitialize loop described in the bug report.
The proper way to note reception of a downstream wakeup request is to set a bit in the hub->event_bits variable instead of hub->change_bits. That way the hub driver will realize that something has happened to the port but will not think the port and child device have been disconnected. This patch makes that change.

commit 1d7d4c07932e04355d6e6528d44a2f2c9e354346 upstream.
When the USB core code for getting root-hub status reports was originally written, it was assumed that the hub driver would be its only caller. But this isn't true now; user programs can use usbfs to communicate with root hubs and get status reports. When they do this, they may use a transfer_buffer that is smaller than the data returned by the HCD, which will lead to a buffer overflow error when usb_hcd_poll_rh_status() tries to store the status data. This was discovered by syzbot:
BUG: KASAN: slab-out-of-bounds in memcpy include/linux/fortify-string.h:225 [inline] BUG: KASAN: slab-out-of-bounds in usb_hcd_poll_rh_status+0x5f4/0x780 drivers/usb/core/hcd.c:776 Write of size 2 at addr ffff88801da403c0 by task syz-executor133/4062
This patch fixes the bug by reducing the amount of status data if it won't fit in the transfer_buffer. If some data gets discarded then the URB's completion status is set to -EOVERFLOW rather than 0, to let the user know what happened.

commit a658c929ded7ea3aee324c8c2a9635a5e5a38e7f upstream.
If cfg80211 is providing extraie's for a scanning process then ath11k will copy that over to the firmware. The extraie.len is a 32 bit value in struct element_info and describes the amount of bytes for the vendor information elements.
The WMI_TLV packet is having a special WMI_TAG_ARRAY_BYTE section. This section can have a (payload) length up to 65535 bytes because the WMI_TLV_LEN can store up to 16 bits. The code was missing such a check and could have created a scan request which cannot be parsed correctly by the firmware.
But the bigger problem was the allocation of the buffer. It has to align the TLV sections by 4 bytes. But the code was using an u8 to store the newly calculated length of this section (with alignment). And the new calculated length was then used to allocate the skbuff. But the actual code to copy in the data is using the extraie.len and not the calculated "aligned" length.
The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled was 264 bytes during tests with a QCA Milan card. But it only allocated 8 bytes (264 bytes % 256) for it. As consequence, the code to memcpy the extraie into the skb was then just overwriting data after skb->end. Things like shinfo were therefore corrupted. This could usually be seen by a crash in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus address).

commit 710ad98c363a66a0cd8526465426c5c5f8377ee0 upstream.
Laurent reported that they have seen a significant amount of TCP retransmissions at high throughput from applications residing in network namespaces talking to the outside world via veths. The drops were seen on the qdisc layer (fq_codel, as per systemd default) of the phys device such as ena or virtio_net due to all traffic hitting a _single_ TX queue _despite_ multi-queue device. (Note that the setup was _not_ using XDP on veths as the issue is generic.)
More specifically, after edbea9220251 ("veth: Store queue_mapping independently of XDP prog presence") which made it all the way back to v4.19.184+, skb_record_rx_queue() would set skb->queue_mapping to 1 (given 1 RX and 1 TX queue by default for veths) instead of leaving at 0.
This is eventually retained and callbacks like ena_select_queue() will also pick single queue via netdev_core_pick_tx()'s ndo_select_queue() once all the traffic is forwarded to that device via upper stack or other means. Similarly, for others not implementing ndo_select_queue() if XPS is disabled, netdev_pick_tx() might call into the skb_tx_hash() and check for prior skb_rx_queue_recorded() as well.
In general, it is a _bad_ idea for virtual devices like veth to mess around with queue selection [by default]. Given dev->real_num_tx_queues is by default 1, the skb->queue_mapping was left untouched, and so prior to edbea9220251 the netdev_core_pick_tx() could do its job upon __dev_queue_xmit() on the phys device.
Unbreak this and restore prior behavior by removing the skb_record_rx_queue() from veth_xmit() altogether.
If the veth peer has an XDP program attached, then it would return the first RX queue index in xdp_md->rx_queue_index (unless configured in non-default manner). However, this is still better than breaking the generic case.

commit 9651cf2cb14726c785240e9dc01b274a68e9959e upstream.
This device is found in the MacBookPro16,2, and as the MacBookPro16,1 is from the same generation of MacBooks and has a UART with bxt_uart_info, it was incorrectly assumed that the MacBookPro16,2's UART would have the same info.
This led to the wrong clock speed being used, and the Bluetooth controller exposed by the UART receiving and sending random data, which was incorrectly assumed to be an issue with the Bluetooth stuff, not an error with the UART side of things.
Changing the info to spt_uart_info changes the clock speed and makes it send and receive data correctly.

In isotp_rcv_ff() 32 bit of data received over the network is assigned to struct tpcon::len. Later in that function the length is checked for the maximal supported length against MAX_MSG_LENGTH.
As struct tpcon::len is an "int" this check does not work, if the provided length overflows the "int".

To fix this problem this patch converts both struct tpcon::{idx,len} to unsigned int.

commit 89d58aebe14a365c25ba6645414afdbf4e41cea4 upstream.
No information is deliberately sent in hf->flags in host -> device communications, but the open-source candleLight firmware echoes it back, which can result in the GS_CAN_FLAG_OVERFLOW flag being set and generating spurious ERRORFRAMEs.
While there also initialize the reserved member with 0.

commit 5d73d1e320c3fd94ea15ba5f79301da9a8bcc7de upstream.
extract_crng() and crng_backtrack_protect() load crng_node_pool with a plain load, which causes undefined behavior if do_numa_crng_init() modifies it concurrently.
Fix this by using READ_ONCE(). Note: as per the previous discussion https://lore.kernel.org/lkml/20211219025139.31085-1-ebiggers@kernel.org/T/#u, READ_ONCE() is believed to be sufficient here, and it was requested that it be used here instead of smp_load_acquire().
Also change do_numa_crng_init() to set crng_node_pool using cmpxchg_release() instead of mb() + cmpxchg(), as the former is sufficient here but is more lightweight.

_extract_crng() does plain loads of crng->init_time and crng_global_init_time, which causes undefined behavior if crng_reseed() and RNDRESEEDCRNG modify these corrently.
Use READ_ONCE() and WRITE_ONCE() to make the behavior defined.
Don't fix the race on crng->init_time by protecting it with crng->lock, since it's not a problem for duplicate reseedings to occur. I.e., the lockless access with READ_ONCE() is fine.

From: Dominik Brodowski linux@dominikbrodowski.net
commit f7e67b8e803185d0aabe7f29d25a35c8be724a78 upstream.
Currently, if CONFIG_RANDOM_TRUST_BOOTLOADER is enabled, multiple calls to add_bootloader_randomness() are broken and can cause a NULL pointer dereference, as noted by Ivan T. Ivanov. This is not only a hypothetical problem, as qemu on arm64 may provide bootloader entropy via EFI and via devicetree.
On the first call to add_hwgenerator_randomness(), crng_fast_load() is executed, and if the seed is long enough, crng_init will be set to 1. On subsequent calls to add_bootloader_randomness() and then to add_hwgenerator_randomness(), crng_fast_load() will be skipped. Instead, wait_event_interruptible() and then credit_entropy_bits() will be called. If the entropy count for that second seed is large enough, that proceeds to crng_reseed().
However, both wait_event_interruptible() and crng_reseed() depends (at least in numa_crng_init()) on workqueues. Therefore, test whether system_wq is already initialized, which is a sufficient indicator that workqueue_init_early() has progressed far enough.
If we wind up hitting the !system_wq case, we later want to do what would have been done there when wqs are up, so set a flag, and do that work later from the rand_initialize() call.

commit 2e70570656adfe1c5d9a29940faa348d5f132199 upstream.
A new warning in clang points out a place in this file where a bitwise OR is being used with boolean types:
drivers/gpu/drm/i915/intel_pm.c:3066:12: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] changed = ilk_increase_wm_latency(dev_priv, dev_priv->wm.pri_latency, 12) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This construct is intentional, as it allows every one of the calls to ilk_increase_wm_latency() to occur (instead of short circuiting with logical OR) while still caring about the result of each call.
To make this clearer to the compiler, use the '|=' operator to assign the result of each ilk_increase_wm_latency() call to changed, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

commit 712a270d2db967b387338c26c3dc04ccac3fcec3 upstream.
The definitions for pdc_toc_pim_11 and pdc_toc_pim_20 are wrong since they include an entry for a hversion field which doesn't exist in the specification.
Fix this and clean up some whitespaces so that the whole file will be in sync with it's copy in the SeaBIOS-hppa sources.
