2023-09-13wifi: mac80211: fix mesh id corruption on 32 bit systemsFelix Fietkau
Since the changed field size was increased to u64, mesh_bss_info_changed pulls invalid bits from the first 3 bytes of the mesh id, clears them, and passes them on to ieee80211_link_info_change_notify, because ifmsh->mbss_changed was not updated to match its size. Fix this by turning into ifmsh->mbss_changed into an unsigned long array with 64 bit size.

2023-09-13tcp: Fix bind() regression for v4-mapped-v6 non-wildcard address.Kuniyuki Iwashima
Since bhash2 was introduced, the example below does not work as expected. These two bind() should conflict, but the 2nd bind() now succeeds. from socket import * s1 = socket(AF_INET6, SOCK_STREAM) s1.bind(('::ffff:127.0.0.1', 0)) s2 = socket(AF_INET, SOCK_STREAM) s2.bind(('127.0.0.1', s1.getsockname()[1])) During the 2nd bind() in inet_csk_get_port(), inet_bind2_bucket_find() fails to find the 1st socket's tb2, so inet_bind2_bucket_create() allocates a new tb2 for the 2nd socket. Then, we call inet_csk_bind_conflict() that checks conflicts in the new tb2 by inet_bhash2_conflict(). However, the new tb2 does not include the 1st socket, thus the bind() finally succeeds. In this case, inet_bind2_bucket_match() must check if AF_INET6 tb2 has the conflicting v4-mapped-v6 address so that inet_bind2_bucket_find() returns the 1st socket's tb2. Note that if we bind two sockets to 127.0.0.1 and then ::FFFF:127.0.0.1, the 2nd bind() fails properly for the same reason mentinoed in the previous commit.

2023-09-13tcp: Fix bind() regression for v4-mapped-v6 wildcard address.Kuniyuki Iwashima
Andrei Vagin reported bind() regression with strace logs. If we bind() a TCPv6 socket to ::FFFF:0.0.0.0 and then bind() a TCPv4 socket to 127.0.0.1, the 2nd bind() should fail but now succeeds. from socket import * s1 = socket(AF_INET6, SOCK_STREAM) s1.bind(('::ffff:0.0.0.0', 0)) s2 = socket(AF_INET, SOCK_STREAM) s2.bind(('127.0.0.1', s1.getsockname()[1])) During the 2nd bind(), if tb->family is AF_INET6 and sk->sk_family is AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check if tb has the v4-mapped-v6 wildcard address. The example above does not work after commit 5456262d2baa ("net: Fix incorrect address comparison when searching for a bind2 bucket"), but the blamed change is not the commit. Before the commit, the leading zeros of ::FFFF:0.0.0.0 were treated as 0.0.0.0, and the sequence above worked by chance. Technically, this case has been broken since bhash2 was introduced. Note that if we bind() two sockets to 127.0.0.1 and then ::FFFF:0.0.0.0, the 2nd bind() fails properly because we fall back to using bhash to detect conflicts for the v4-mapped-v6 address.

2023-09-12selinux: fix handling of empty opts in selinux_fs_context_submount()Ondrej Mosnacek
selinux_set_mnt_opts() relies on the fact that the mount options pointer is always NULL when all options are unset (specifically in its !selinux_initialized() branch. However, the new selinux_fs_context_submount() hook breaks this rule by allocating a new structure even if no options are set. That causes any submount created before a SELinux policy is loaded to be rejected in selinux_set_mnt_opts(). Fix this by making selinux_fs_context_submount() leave fc->security set to NULL when there are no options to be copied from the reference superblock.

It was reported that under certain circumstances GCC emits ENDBR instructions for _THIS_IP_ usage. Specifically, when it appears at the start of a basic block -- but not elsewhere. Since _THIS_IP_ is never used for control flow, these ENDBR instructions are completely superfluous. Override the _THIS_IP_ definition for x86_64 to avoid this. Less ENDBR instructions is better.

2023-09-12veth: Update XDP feature set when bringing up deviceToke Høiland-Jørgensen
There's an early return in veth_set_features() if the device is in a down state, which leads to the XDP feature flags not being updated when enabling GRO while the device is down. Which in turn leads to XDP_REDIRECT not working, because the redirect code now checks the flags. Fix this by updating the feature flags after bringing the device up.

2023-09-12NFSD: fix possible oops when nfsd/pool_stats is closed.NeilBrown
If /proc/fs/nfsd/pool_stats is open when the last nfsd thread exits, then when the file is closed a NULL pointer is dereferenced. This is because nfsd_pool_stats_release() assumes that the pointer to the svc_serv cannot become NULL while a reference is held. This used to be the case but a recent patch split nfsd_last_thread() out from nfsd_put(), and clearing the pointer is done in nfsd_last_thread(). This is easily reproduced by running rpc.nfsd 8 ; ( rpc.nfsd 0;true) < /proc/fs/nfsd/pool_stats Fortunately nfsd_pool_stats_release() has easy access to the svc_serv pointer, and so can call svc_put() on it directly.

If jack-detection is not used; or has already been disabled then there is no need to call rt5640_cancel_work(). Move the rt5640_cancel_work() inside the "if (rt5640->jack) {}" block, grouping it together with the disabling of the IRQ which queues the work in the first place.

2023-09-12ASoC: rt5640: Do not disable/enable IRQ twice on suspend/resumeHans de Goede
When jack-detect was originally added disabling the IRQ during suspend was done by the sound/soc/intel/boards/bytcr_rt5640.c driver calling snd_soc_component_set_jack(NULL) on suspend, which calls rt5640_disable_jack_detect(), which calls free_irq() which also disables it. Commit 5fabcc90e79b ("ASoC: rt5640: Fix Jack work after system suspend") added disable_irq() / enable_irq() calls on suspend/resume for machine drivers which do not call snd_soc_component_set_jack(NULL) on suspend. The new disable_irq() / enable_irq() are made conditional by "if (rt5640->irq)" statements, but this is true for the machine drivers which do call snd_soc_component_set_jack(NULL) on suspend too, causing a disable_irq() call there on the already free-ed IRQ. Change the "if (rt5640->irq)" condition to "if (rt5640->jack)" to fix this, rt5640->jack is only set if the jack-detect IRQ handler is still active when rt5640_suspend() runs. And adjust rt5640_enable_hda_jack_detect()'s request_irq() error handling to set rt5640->jack to NULL to match (note that the old setting of irq to -ENOXIO still resulted in disable_irq(-ENOXIO) calls on suspend).

2023-09-12ASoC: rt5640: Revert "Fix sleep in atomic context"Hans de Goede
Commit 70a6404ff610 ("ASoC: rt5640: Fix sleep in atomic context") not only switched from request_irq() to request_threaded_irq(), to fix the sleep in atomic context issue, but it also added devm management of the IRQ by actually switching to devm_request_threaded_irq() (without any explanation in the commit message for this change). This is wrong since the IRQ was already explicitly managed by the driver. On unbind the ASoC core will call rt5640_set_jack(NULL) which in turn will call rt5640_disable_jack_detect() which frees the IRQ already. So now we have a double free. Besides the unexplained switch to devm being wrong, the actual fix for the sleep in atomic context issue also is not the best solution. The only thing which rt5640_irq() does is cancel + (re-)queue the jack_work delayed_work. This can be done in a single non sleeping call by replacing queue_delayed_work() with mod_delayed_work(), which does not sleep. Using mod_delayed_work() is a much better fix then adding a thread which does nothing other then queuing a work-item. This patch is a straight revert of the troublesome changes, the switch to mod_delayed_work() is done in a separate follow-up patch.
