2023-01-12platform/x86: dell-privacy: Only register SW_CAMERA_LENS_COVER if presentHans de Goede
Unlike keys where userspace only reacts to keypresses, userspace may act on switches in both (0 and 1) of their positions. For example if a SW_TABLET_MODE switch is registered then GNOME will not automatically show the onscreen keyboard when a text field gets focus on touchscreen devices when SW_TABLET_MODE reports 0 and when SW_TABLET_MODE reports 1 libinput will block (filter out) builtin keyboard and touchpad events. So to avoid unwanted side-effects EV_SW type inputs should only be registered if they are actually present, only register SW_CAMERA_LENS_COVER if it is actually there.

2023-01-12platform/surface: aggregator: Ignore command messages not intended for usMaximilian Luz
It is possible that we (the host/kernel driver) receive command messages that are not intended for us. Ignore those for now. The whole story is a bit more complicated: It is possible to enable debug output on SAM, which is sent via SSH command messages. By default this output is sent to a debug connector, with its own target ID (TID=0x03). It is possible to override the target of the debug output and set it to the host/kernel driver. This, however, does not change the original target ID of the message. Meaning, we receive messages with TID=0x03 (debug) but expect to only receive messages with TID=0x00 (host). The problem is that the different target ID also comes with a different scope of request IDs. In particular, these do not follow the standard event rules (i.e. do not fall into a set of small reserved values). Therefore, current message handling interprets them as responses to pending requests and tries to match them up via the request ID. However, these debug output messages are not in fact responses, and therefore this will at best fail to find the request and at worst pass on the wrong data as response for a request. Therefore ignore any command messages not intended for us (host) for now. We can implement support for the debug messages once we have a better understanding of them. Note that this may also provide a bit more stability and avoid some driver confusion in case any other targets want to talk to us in the future, since we don't yet know what to do with those as well. A warning for the dropped messages should suffice for now and also give us a chance of discovering new targets if they come along without any potential for bugs/instabilities.

2023-01-12io_uring/poll: attempt request issue after racy poll wakeupJens Axboe
If we have multiple requests waiting on the same target poll waitqueue, then it's quite possible to get a request triggered and get disappointed in not being able to make any progress with it. If we race in doing so, we'll potentially leave the poll request on the internal tables, but removed from the waitqueue. That means that any subsequent trigger of the poll waitqueue will not kick that request into action, causing an application to potentially wait for completion of a request that will never happen. Fix this by adding a new poll return state, IOU_POLL_REISSUE. Rather than have complicated logic for how to re-arm a given type of request, just punt it for a reissue. While in there, move the 'ret' variable to the only section where it gets used. This avoids confusion the scope of it.

2023-01-12btrfs: do not abort transaction on failure to update log rootFilipe Manana
When syncing a log, if we fail to update a log root in the log root tree, we are aborting the transaction if the failure was not -ENOSPC. This is excessive because there is a chance that a transaction commit can succeed, and therefore avoid to turn the filesystem into RO mode. All we need to be careful about is to mark the log for a full commit, which we already do, to make sure no one commits a super block pointing to an outdated log root tree. So don't abort the transaction if we fail to update a log root in the log root tree, and log an error if the failure is not -ENOSPC, so that it does not go completely unnoticed.

2023-01-12btrfs: do not abort transaction on failure to write log tree when syncing logFilipe Manana
When syncing the log, if we fail to write log tree extent buffers, we mark the log for a full commit and abort the transaction. However we don't need to abort the transaction, all we really need to do is to make sure no one can commit a superblock pointing to new log tree roots. Just because we got a failure writing extent buffers for a log tree, it does not mean we will also fail to do a transaction commit. One particular case is if due to a bug somewhere, when writing log tree extent buffers, the tree checker detects some corruption and the writeout fails because of that. Aborting the transaction can be very disruptive for a user, specially if the issue happened on a root filesystem. One example is the scenario in the Link tag below, where an isolated corruption on log tree leaves was causing transaction aborts when syncing the log.

2023-01-12btrfs: add missing setup of log for full commit at add_conflicting_inode()Filipe Manana
When logging conflicting inodes, if we reach the maximum limit of inodes, we return BTRFS_LOG_FORCE_COMMIT to force a transaction commit. However we don't mark the log for full commit (with btrfs_set_log_full_commit()), which means that once we leave the log transaction and before we commit the transaction, some other task may sync the log, which is incomplete as we have not logged all conflicting inodes, leading to some inconsistent in case that log ends up being replayed. So also call btrfs_set_log_full_commit() at add_conflicting_inode().

2023-01-12btrfs: fix directory logging due to race with concurrent index key deletionFilipe Manana
Sometimes we log a directory without holding its VFS lock, so while we logging it, dir index entries may be added or removed. This typically happens when logging a dentry from a parent directory that points to a new directory, through log_new_dir_dentries(), or when while logging some other inode we also need to log its parent directories (through btrfs_log_all_parents()). This means that while we are at log_dir_items(), we may not find a dir index key we found before, because it was deleted in the meanwhile, so a call to btrfs_search_slot() may return 1 (key not found). In that case we return from log_dir_items() with a success value (the variable 'err' has a value of 0). This can lead to a few problems, specially in the case where the variable 'last_offset' has a value of (u64)-1 (and it's initialized to that when it was declared): 1) By returning from log_dir_items() with success (0) and a value of (u64)-1 for '*last_offset_ret', we end up not logging any other dir index keys that follow the missing, just deleted, index key. The (u64)-1 value makes log_directory_changes() not call log_dir_items() again; 2) Before returning with success (0), log_dir_items(), will log a dir index range item covering a range from the last old dentry index (stored in the variable 'last_old_dentry_offset') to the value of 'last_offset'. If 'last_offset' has a value of (u64)-1, then it means if the log is persisted and replayed after a power failure, it will cause deletion of all the directory entries that have an index number between last_old_dentry_offset + 1 and (u64)-1; 3) We can end up returning from log_dir_items() with ctx->last_dir_item_offset having a lower value than inode->last_dir_index_offset, because the former is set to the current key we are processing at process_dir_items_leaf(), and at the end of log_directory_changes() we set inode->last_dir_index_offset to the current value of ctx->last_dir_item_offset. So if for example a deletion of a lower dir index key happened, we set ctx->last_dir_item_offset to that index value, then if we return from log_dir_items() because btrfs_search_slot() returned 1, we end up returning from log_dir_items() with success (0) and then log_directory_changes() sets inode->last_dir_index_offset to a lower value than it had before. This can result in unpredictable and unexpected behaviour when we need to log again the directory in the same transaction, and can result in ending up with a log tree leaf that has duplicated keys, as we do batch insertions of dir index keys into a log tree. So fix this by making log_dir_items() move on to the next dir index key if it does not find the one it was looking for.

2023-01-12btrfs: fix missing error handling when logging directory itemsFilipe Manana
When logging a directory, at log_dir_items(), if we get an error when attempting to search the subvolume tree for a dir index item, we end up returning 0 (success) from log_dir_items() because 'err' is left with a value of 0. This can lead to a few problems, specially in the case the variable 'last_offset' has a value of (u64)-1 (and it's initialized to that when it was declared): 1) By returning from log_dir_items() with success (0) and a value of (u64)-1 for '*last_offset_ret', we end up not logging any other dir index keys that follow the missing, just deleted, index key.

2023-01-12Merge branch 'vsock-update-tools-and-error-handling'Paolo Abeni
Arseniy Krasnov says: ==================== vsock: update tools and error handling Patchset consists of two parts: 1) Kernel patch One patch from Bobby Eshleman. I took single patch from Bobby: https://lore.kernel.org/lkml/d81818b868216c774613dd03641fcfe63cc55a45 .1660362668.git.bobby.eshleman@bytedance.com/ and use only part for af_vsock.c, as VMCI and Hyper-V parts were rejected. I used it, because for SOCK_SEQPACKET big messages handling was broken - ENOMEM was returned instead of EMSGSIZE. And anyway, current logic which always replaces any error code returned by transport to ENOMEM looks strange for me also(for example in EMSGSIZE case it was changed to ENOMEM). 2) Tool patches Since there is work on several significant updates for vsock(virtio/ vsock especially): skbuff, DGRAM, zerocopy rx/tx, so I think that this patchset will be useful. This patchset updates vsock tests and tools a little bit. First of all it updates test suite: two new tests are added. One test is reworked message bound test. Now it is more complex. Instead of sending 1 byte messages with one MSG_EOR bit, it sends messages of random length(one half of messages are smaller than page size, second half are bigger) with random number of MSG_EOR bits set. Receiver also don't know total number of messages. Message bounds control is maintained by hash sum of messages length calculation. Second test is for SOCK_SEQPACKET - it tries to send message with length more than allowed. I think both tests will be useful for DGRAM support also. Third thing that this patchset adds is small utility to test vsock performance for both rx and tx. I think this util could be useful as 'iperf'/'uperf', because: 1) It is small comparing to 'iperf' or 'uperf', so it very easy to add new mode or feature to it(especially vsock specific). 2) It allows to set SO_RCVLOWAT and SO_VM_SOCKETS_BUFFER_SIZE option. Whole throughtput depends on both parameters. 3) It is located in the kernel source tree, so it could be updated by the same patchset which changes related kernel functionality in vsock. I used this util very often to check performance of my rx zerocopy support(this tool has rx zerocopy support, but not in this patchset).

2023-01-12x86/mm: fix poking_init() for Xen PV guestsJuergen Gross
Commit 3f4c8211d982 ("x86/mm: Use mm_alloc() in poking_init()") broke the kernel for running as Xen PV guest. It seems as if the new address space is never activated before being used, resulting in Xen rejecting to accept the new CR3 value (the PGD isn't pinned). Fix that by adding the now missing call of paravirt_arch_dup_mmap() to poking_init(). That call was previously done by dup_mm()->dup_mmap() and it is a NOP for all cases but for Xen PV, where it is just doing the pinning of the PGD.

2023-01-11devlink: keep the instance mutex alive until references are goneJakub Kicinski
The reference needs to keep the instance memory around, but also the instance lock must remain valid. Users will take the lock, check registration status and release the lock. mutex_destroy() etc. belong in the same place as the freeing of the memory. Unfortunately lockdep_unregister_key() sleeps so we need to switch the an rcu_work. Note that the problem is a bit hard to repro, because devlink_pernet_pre_exit() iterates over registered instances. AFAIU the instances must get devlink_free()d concurrently with the namespace getting deleted for the problem to occur.
