[PATCH] irqchip/sifive-plic: Unmask interrupt in plic_irq_enable()

by Nam Cao

It is possible that an interrupt is disabled and masked at the same time. When the interrupt is enabled again by enable_irq(), only plic_irq_enable() is called, not plic_irq_unmask(). The interrupt remains masked and never raises. An example where interrupt is both disabled and masked is when handle_fasteoi_irq() is the handler, and IRQS_ONESHOT is set. The interrupt handler: 1. Mask the interrupt 2. Handle the interrupt 3. Check if interrupt is still enabled, and unmask it (see cond_unmask_eoi_irq()) If another task disables the interrupt in the middle of the above steps, the interrupt will not get unmasked, and will remain masked when it is enabled in the future. The problem is occasionally observed when PREEMPT_RT is enabled, because PREEMPT_RT add the IRQS_ONESHOT flag. But PREEMPT_RT only makes the problem more likely to appear, the bug has been around since commit a1706a1c5062 ("irqchip/sifive-plic: Separate the enable and mask operations"). Fix it by unmasking interrupt in plic_irq_enable(). Fixes: a1706a1c5062 ("irqchip/sifive-plic: Separate the enable and mask operations").

[PATCH] drm/panthor: Don't add write fences to the shared BOs

by Boris Brezillon

The only user (the mesa gallium driver) is already assuming explicit synchronization and doing the export/import dance on shared BOs. The only reason we were registering ourselves as writers on external BOs is because Xe, which was the reference back when we developed Panthor, was doing so. Turns out Xe was wrong, and we really want bookkeep on all registered fences, so userspace can explicitly upgrade those to read/write when needed.

[PATCH] drm/panthor: Don't declare a queue blocked if deferred operations are pending

by Boris Brezillon

If deferred operations are pending, we want to wait for those to land before declaring the queue blocked on a SYNC_WAIT. We need this to deal with the case where the sync object is signalled through a deferred SYNC_{ADD,SET} from the same queue. If we don't do that and the group gets scheduled out before the deferred SYNC_{SET,ADD} is executed, we'll end up with a timeout, because no external SYNC_{SET,ADD} will make the scheduler reconsider the group for execution.

[PATCH v6.6-v4.19] wifi: mac80211: Avoid address calculations via out of bounds array indexing

by hsimeliere.opensource＠witekio.com

From: Kenton Groombridge <concord(a)gentoo.org> commit 2663d0462eb32ae7c9b035300ab6b1523886c718 upstream. req->n_channels must be set before req->channels[] can be used. This patch fixes one of the issues encountered in [1].

[PATCH 6.1 0/2] io_uring/io-wq: respect cgroup cpusets

by Felix Moessbauer

Hi, as discussed in [1], this is a manual backport of the remaining two patches to let the io worker threads respect the affinites defined by the cgroup of the process. In 6.1 one worker is created per NUMA node, while in da64d6db3bd3 ("io_uring: One wqe per wq") this is changed to only have a single worker. As this patch is pretty invasive, Jens and me agreed to not backport it. Instead we now limit the workers cpuset to the cpus that are in the intersection between what the cgroup allows and what the NUMA node has. This leaves the question what to do in case the intersection is empty: To be backwarts compatible, we allow this case, but restrict the cpumask of the poller to the cpuset defined by the cgroup. We further believe this is a reasonable decision, as da64d6db3bd3 drops the NUMA awareness anyways.
