2024-09-09io_uring/sqpoll: do not allow pinning outside of cpusetFelix Moessbauer
The submit queue polling threads are userland threads that just never exit to the userland. When creating the thread with IORING_SETUP_SQ_AFF, the affinity of the poller thread is set to the cpu specified in sq_thread_cpu. However, this CPU can be outside of the cpuset defined by the cgroup cpuset controller. This violates the rules defined by the cpuset controller and is a potential issue for realtime applications. In b7ed6d8ffd6 we fixed the default affinity of the poller thread, in case no explicit pinning is required by inheriting the one of the creating task. In case of explicit pinning, the check is more complicated, as also a cpu outside of the parent cpumask is allowed. We implemented this by using cpuset_cpus_allowed (that has support for cgroup cpusets) and testing if the requested cpu is in the set.

The DPI display interface feeds the external display pipeline. However the pipeline representation is currently incomplete. Efforts are still under way to come up with a way to represent the "creative" repurposing of the DP bridge chip's internal output mux, which is meant to support USB type-C orientation changes, to output to one of two type-C ports. Until that is finalized, the external display can't be fully described, and thus won't work. Even worse, the half complete graph potentially confuses the OS, breaking the internal display as well. Disable the external display interface across the whole Corsola family until the DP / USB Type-C muxing graph binding is ready.

2024-09-09debugobjects: Remove redundant checks in fill_pool()Zhen Lei
fill_pool() checks locklessly at the beginning whether the pool has to be refilled. After that it checks locklessly in a loop whether the free list contains objects and repeats the refill check. If both conditions are true, it acquires the pool lock and tries to move objects from the free list to the pool repeating the same checks again. There are two redundant issues with that: 1) The repeated check for the fill condition 2) The loop processing The repeated check is pointless as it was just established that fill is required. The condition has to be re-evaluated under the lock anyway. The loop processing is not required either because there is practically zero chance that a repeated attempt will succeed if the checks under the lock terminate the moving of objects. Remove the redundant check and replace the loop with a simple if condition.

fill_pool() uses 'obj_pool_min_free' to decide whether objects should be handed back to the kmem cache.

2024-09-09ALSA: hda: Use non-SG allocation for the communication buffersTakashi Iwai
The azx_bus->dma_type is referred only for allocating the communication buffers like CORB/RIRB, and the allocation size is small. Hence it doesn't have to be S/G buffer allocation, which is an obvious overkill. Use the standard SNDRV_DMA_TYPE_DEV_WC instead. This was changed to SNDRV_DMA_TYPE_DEV_WC_SG in the commit 37137ec26c2c ("ALSA: hda: Once again fix regression of page allocations with IOMMU") as a workaround for IOMMU-backed allocations. But this is no longer needed since the allocation with SNDRV_DMA_TYPE_DEV_WC itself was fixed in the commit 9c27301342a5 ("ALSA: memalloc: Use DMA API for x86 WC page allocations, too"). So this patch reverts the previous workaround in this piece of code. Link: https://patch.msgid.link/20240909134744.25426-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2024-09-09bcachefs: Annotate bch_replicas_entry_{v0,v1} with __counted_by()Thorsten Blum
Add the __counted_by compiler attribute to the flexible array members devs to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and CONFIG_FORTIFY_SOURCE. Increment nr_devs before adding a new device to the devs array and adjust the array indexes accordingly. Add a helper macro for adding a new device. In bch2_journal_read(), explicitly set nr_devs to 0. Signed-off-by: Thorsten Blum <thorsten.blum@toblux.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: support idmap mountsHongbo Li
We enable idmapped mounts for bcachefs. Here, we just pass down the user_namespace argument from the VFS methods to the relevant helpers. The idmap test in bcachefs is as following: ``` 1. losetup /dev/loop1 bcachefs.img 2. ./bcachefs format /dev/loop1 3. mount -t bcachefs /dev/loop1 /mnt/bcachefs/ 4. ./mount-idmapped --map-mount b:0:1000:1 /mnt/bcachefs /mnt/idmapped1/ ll /mnt/bcachefs total 2 drwx------. 2 root root 0 Jun 14 14:10 lost+found -rw-r--r--. 1 root root 1945 Jun 14 14:12 profile ll /mnt/idmapped1/ total 2 drwx------. 2 1000 1000 0 Jun 14 14:10 lost+found -rw-r--r--. 1 1000 1000 1945 Jun 14 14:12 profile Signed-off-by: Hongbo Li <lihongbo22@huawei.com> Reviewed-by: Christian Brauner <brauner@kernel.org> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-09-09bcachefs: Refactor bch2_bset_fix_lookup_tableAlan Huang
bch2_bset_fix_lookup_table is too complicated to be easily understood, the comment "l now > where" there is also incorrect when where == t->end_offset. This patch therefore refactor the function, the idea is that when where >= rw_aux_tree(b, t)[t->size - 1].offset, we don't need to adjust the rw aux tree.

2024-09-09bcachefs: Assert that we don't lock nodes when !trans->lockedKent Overstreet
We rely on the trans->locked to know if a trans has nodes locked for assertions about deadlocks; there can't be more than one trans in the same process that is locked. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Do not check folio_has_private()Matthew Wilcox (Oracle)
folio_has_private() is an attractive nuisance; filesystem authors generally don't realise that it actually checks two flags (one of which is never set by bcachefs). There's no need to check the private flag at all; for folios owned by bcachefs, we know that folio->private is NULL when the private flag is clear and non-NULL when the private flag is set.

2024-09-09bcachefs: drop unused posix acl handlersYouling Tang
Remove struct nop_posix_acl_{access,default} for bcachefs filesystem that don't depend on the xattr handler in their inode->i_op->listxattr() method in any way. There's nothing more to do than to simply remove the handler. It's been effectively unused ever since we introduced the new posix acl api. See [1] for details.
