2023-07-06apparmor: fix: kzalloc perms tables for shared dfasJohn Johansen
Currently the permstables of the shared dfas are not shared, and need to be allocated and copied. In the future this should be addressed with a larger rework on dfa and pdb ref counts and structure sharing.

2023-07-06apparmor: fix profile verification and enable itJohn Johansen
The transition table size was not being set by compat mappings resulting in the profile verification code not being run. Unfortunately the checks were also buggy not being correctly updated from the old accept perms, to the new layout. Also indicate to userspace that the kernel has the permstable verification fixes.

2023-07-06ALSA: jack: Fix mutex call in snd_jack_report()Takashi Iwai
snd_jack_report() is supposed to be callable from an IRQ context, too, and it's indeed used in that way from virtsnd driver. The fix for input_dev race in commit 1b6a6fc5280e ("ALSA: jack: Access input_dev under mutex"), however, introduced a mutex lock in snd_jack_report(), and this resulted in a potential sleep-in-atomic. For addressing that problem, this patch changes the relevant code to use the object get/put and removes the mutex usage. That is, snd_jack_report(), it takes input_get_device() and leaves with input_put_device() for assuring the input_dev being assigned. Although the whole mutex could be reduced, we keep it because it can be still a protection for potential races between creation and deletion.

2023-07-06ASoC/soundwire/qdsp6/wcd: fix leaks and probe deferralMark Brown
Merge series from Johan Hovold <johan+linaro@kernel.org>: I've been hitting a race during boot which breaks probe of the sound card on the Lenovo ThinkPad X13s as I've previously reported here: https://lore.kernel.org/all/ZIHMMFtuDtvdpFAZ@hovoldconsulting.com/ The immediate issue appeared to be a probe deferral that was turned into a hard failure, but addressing that in itself only made things worse as it exposed further bugs. I was hoping someone more familiar with the code in question would look into this, but as this affects users of the X13s and breaks audio on my machine every fifth boot or so, I decided to investigate it myself. As expected, the Qualcomm codec drivers are broken and specifically leak resources on component remove, which in turn breaks sound card probe deferrals. The source of the deferral itself appears to be legitimate and was simply due to some audio component not yet having been registered due to random changes in timing during boot. These issues can most easily be reproduced by simply blacklisting the q6apm_dai module and loading it manually after boot. Included are also two patches that suppresses error messages on component probe deferral to avoid spamming the logs during boot.

Use the bpf_timer_set_callback helper to mark timer_cb as an async callback, and put a direct call to timer_cb in the main subprog.

2023-07-05bpf: Fix max stack depth check for async callbacksKumar Kartikeya Dwivedi
The check_max_stack_depth pass happens after the verifier's symbolic execution, and attempts to walk the call graph of the BPF program, ensuring that the stack usage stays within bounds for all possible call chains. There are two cases to consider: bpf_pseudo_func and bpf_pseudo_call. In the former case, the callback pointer is loaded into a register, and is assumed that it is passed to some helper later which calls it (however there is no way to be sure), but the check remains conservative and accounts the stack usage anyway. For this particular case, asynchronous callbacks are skipped as they execute asynchronously when their corresponding event fires. The case of bpf_pseudo_call is simpler and we know that the call is definitely made, hence the stack depth of the subprog is accounted for. However, the current check still skips an asynchronous callback even if a bpf_pseudo_call was made for it. This is erroneous, as it will miss accounting for the stack usage of the asynchronous callback, which can be used to breach the maximum stack depth limit. Fix this by only skipping asynchronous callbacks when the instruction is not a pseudo call to the subprog. Fixes: 7ddc80a476c2 ("bpf: Teach stack depth check about async callbacks.")

2023-07-05Merge patch series "Improve checks in blk_revalidate_disk_zones()"Martin K. Petersen
Damien Le Moal <dlemoal@kernel.org> says: blk_revalidate_disk_zones() implements checks of the zones of a zoned block device, verifying that the zone size is a power of 2 number of sectors, that all zones (except possibly the last one) have the same size and that zones cover the entire addressing space of the device. While these checks are appropriate to verify that well tested hardware devices have an adequate zone configurations, they lack in certain areas which may result in issues with potentially buggy emulated devices implemented with user drivers such as ublk or tcmu. Specifically, this function does not check if the device driver indicated support for the mandatory zone append writes, that is, if the device max_zone_append_sectors queue limit is set to a non-zero value. Additionally, invalid zones such as a zero length zone with a start sector equal to the device capacity will not be detected and result in out of bounds use of the zone bitmaps prepared with the callback function blk_revalidate_zone_cb(). This series address these issues by modifying the 4 block device drivers that currently support zoned block devices to ensure that they all set a zoned device zone size and max zone append sectors limit before executing blk_revalidate_disk_zones(). With these changes in place, patch 5 improves blk_revalidate_disk_zones() to address the missing checks, relying on the fact that the zone size and zone append limit are normally set when this function is called.

2023-07-05scsi: block: Improve checks in blk_revalidate_disk_zones()Damien Le Moal
blk_revalidate_disk_zones() implements checks of the zones of a zoned block device, verifying that the zone size is a power of 2 number of sectors, that all zones (except possibly the last one) have the same size and that zones cover the entire addressing space of the device. While these checks are appropriate to verify that well tested hardware devices have an adequate zone configurations, they lack in certain areas which may result in issues with emulated devices implemented with user drivers such as ublk or tcmu. Specifically, this function does not check if the device driver indicated support for the mandatory zone append writes, that is, if the device max_zone_append_sectors queue limit is set to a non-zero value. Additionally, invalid zones such as a zero length zone with a start sector equal to the device capacity will not be detected and result in out of bounds use of the zone bitmaps prepared with the callback function blk_revalidate_zone_cb(). Improve blk_revalidate_disk_zones() to address these inadequate checks, relying on the fact that all device drivers supporting zoned block devices must set the device zone size (chunk_sectors queue limit) and the max_zone_append_sectors queue limit before executing this function. The check for a non-zero max_zone_append_sectors value is done in blk_revalidate_disk_zones() before executing the zone report. The zone report callback function blk_revalidate_zone_cb() is also modified to add a check that a zone start is below the device capacity. The check that the zone size is a power of 2 number of sectors is moved to blk_revalidate_disk_zones() as the zone size is already known. Similarly, the number of zones of the device can be calculated in blk_revalidate_disk_zones() before executing the zone report. The kdoc comment for blk_revalidate_disk_zones() is also updated to mention that device drivers must set the device zone size and the max_zone_append_sectors queue limit before calling this function.
