2024-07-02fs: better handle deep ancestor chains in is_subdir()Christian Brauner
Jan reported that 'cd ..' may take a long time in deep directory hierarchies under a bind-mount. If concurrent renames happen it is possible to livelock in is_subdir() because it will keep retrying. Change is_subdir() from simply retrying over and over to retry once and then acquire the rename lock to handle deep ancestor chains better. The list of alternatives to this approach were less then pleasant. Change the scope of rcu lock to cover the whole walk while at it. A big thanks to Jan and Linus. Both Jan and Linus had proposed effectively the same thing just that one version ended up being slightly more elegant.

2024-07-02filelock: Remove locks reliably when fcntl/close race is detectedJann Horn
When fcntl_setlk() races with close(), it removes the created lock with do_lock_file_wait(). However, LSMs can allow the first do_lock_file_wait() that created the lock while denying the second do_lock_file_wait() that tries to remove the lock. In theory (but AFAIK not in practice), posix_lock_file() could also fail to remove a lock due to GFP_KERNEL allocation failure (when splitting a range in the middle). After the bug has been triggered, use-after-free reads will occur in lock_get_status() when userspace reads /proc/locks. This can likely be used to read arbitrary kernel memory, but can't corrupt kernel memory. This only affects systems with SELinux / Smack / AppArmor / BPF-LSM in enforcing mode and only works from some security contexts. Fix it by calling locks_remove_posix() instead, which is designed to reliably get rid of POSIX locks associated with the given file and files_struct and is also used by filp_flush().

2024-07-02ACPI: processor_idle: Fix invalid comparison with insertion sort for latencyKuan-Wei Chiu
The acpi_cst_latency_cmp() comparison function currently used for sorting C-state latencies does not satisfy transitivity, causing incorrect sorting results. Specifically, if there are two valid acpi_processor_cx elements A and B and one invalid element C, it may occur that A < B, A = C, and B = C. Sorting algorithms assume that if A < B and A = C, then C < B, leading to incorrect ordering. Given the small size of the array (<=8), we replace the library sort function with a simple insertion sort that properly ignores invalid elements and sorts valid ones based on latency. This change ensures correct ordering of the C-state latencies.

2024-07-02btrfs: fix uninitialized return value in the ref-verify toolFilipe Manana
In the ref-verify tool, when processing the inline references of an extent item, we may end up returning with uninitialized return value, because: 1) The 'ret' variable is not initialized if there are no inline extent references ('ptr' == 'end' before the while loop starts); 2) If we find an extent owner inline reference we don't initialize 'ret'. So fix these cases by initializing 'ret' to 0 when declaring the variable and set it to -EINVAL if we find an extent owner inline references and simple quotas are not enabled (as well as print an error message).

[CAUSE] That offending commit skips the whole qgroup inherit check if qgroup is not enabled. But that also skips the very basic checks like num_ref_copies/num_excl_copies and the structure size checks. Meaning if a qgroup enable/disable race is happening at the background, and we pass a btrfs_qgroup_inherit structure when the qgroup is disabled, the check would be completely skipped. Then at the time of transaction commitment, qgroup is re-enabled and btrfs_qgroup_inherit() is going to use the incorrect structure and causing the above KASAN error. [FIX] Make btrfs_qgroup_check_inherit() only skip the source qgroup checks. So that even if invalid btrfs_qgroup_inherit structure is passed in, we can still reject invalid ones no matter if qgroup is enabled or not. Furthermore we do already have an extra safety inside btrfs_qgroup_inherit(), which would just ignore invalid qgroup sources, so even if we only skip the qgroup source check we're still safe.

2024-07-02btrfs: zoned: fix calc_available_free_space() for zoned modeNaohiro Aota
calc_available_free_space() returns the total size of metadata (or system) block groups, which can be allocated from unallocated disk space. The logic is wrong on zoned mode in two places. First, the calculation of data_chunk_size is wrong. We always allocate one zone as one chunk, and no partial allocation of a zone. So, we should use zone_size (= data_sinfo->chunk_size) as it is. Second, the result "avail" may not be zone aligned. Since we always allocate one zone as one chunk on zoned mode, returning non-zone size aligned bytes will result in less pressure on the async metadata reclaim process. This is serious for the nearly full state with a large zone size device. Allowing over-commit too much will result in less async reclaim work and end up in ENOSPC. We can align down to the zone size to avoid that.

2024-07-02io_uring/net: don't clear msg_inq before io_recv_buf_select() needs itJens Axboe
For bundle receives to function properly, the previous iteration msg_inq value is needed to make a judgement call on how much data there is to receive. A previous fix ended up clearing it earlier as an error case would potentially errantly set IORING_CQE_F_SOCK_NONEMPTY if the request got failed. Move the assignment to post assigning buffers for the receive, but ensure that it's cleared for the buffer selection error case. With that, buffer selection has the right msg_inq value and can correctly bundle receives as designed. Noticed while testing where it was apparent than more than 1 buffer was never received. After fix was in place, multiple buffers are correctly picked for receive. This provides a 10x speedup for the test case, as the buffer size used was 64b.

As it turns out, there is a large number of out-of-tree DTSes (in OpenWrt project) that used to specify incorrect (active high) polarity for the Lantiq reset GPIO, so to keep compatibility while they are being updated a quirk for force the polarity low is needed. Luckily these old DTSes used nonstandard name for the property ("gpio-reset" vs "reset-gpios") so the quirk will not hurt if there are any new devices that need inverted polarity as they can specify the right polarity in their DTS when using the standard "reset-gpios" property. Additionally the condition to enable the transition from standard to non-standard reset GPIO property name was inverted and the replacement name for the property was not correct. Fix this as well.

2024-07-02fs_parse: add uid & gid option option parsing helpersEric Sandeen
Multiple filesystems take uid and gid as options, and the code to create the ID from an integer and validate it is standard boilerplate that can be moved into common helper functions, so do that for consistency and less cut&paste. This also helps avoid the buggy pattern noted by Seth Jenkins at https://lore.kernel.org/lkml/CALxfFW4BXhEwxR0Q5LSkg-8Vb4r2MONKCcUCVioehXQKr35eHg@mail.gmail.com/ because uid/gid parsing will fail before any assignment in most filesystems.

2024-07-01e1000e: Fix S0ix residency on corporate systemsDima Ruinskiy
On vPro systems, the configuration of the I219-LM to achieve power gating and S0ix residency is split between the driver and the CSME FW. It was discovered that in some scenarios, where the network cable is connected and then disconnected, S0ix residency is not always reached. This was root-caused to a subset of I219-LM register writes that are not performed by the CSME FW. Therefore, the driver should perform these register writes on corporate setups, regardless of the CSME FW state. This was discovered on Meteor Lake systems; however it is likely to appear on other platforms as well.

2024-07-01Revert "dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries"Komal Bajaj
This reverts commit f0f99f371822c48847e02e56d6e7de507e18f186. QDU1000 has 7 register regions. The earlier commit 8e2506d01231 ("dt-bindings: cache: qcom,llcc: Add LLCC compatible for QDU1000/QRU1000") to add llcc compatible was reflecting the same, but dtsi change for QDU1000 was not aligning with its binding. Later, commit f0f99f371822 ("dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries") was merged intended to fix this misalignment. After the LLCC driver refactor, each LLCC bank/channel need to be represented as one register space to avoid mapping to the region where access is not there. Hence, revert the commit f0f99f371822 ("dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries") to align QDU1000 llcc binding with its dtsi node.

2024-07-01bcachefs: io clock: run timer fns under clock lockKent Overstreet
We don't have a way to flush a timer that's executing the callback, and this is simple and limited enough in scope that we can just use the lock instead. Needed for the next patch that adds direct wakeups from the allocator to copygc, where we're now more frequently calling io_timer_del() on an expiring timer.

2024-07-01clk: mediatek: mt8183: Only enable runtime PM on mt8183-mfgcfgPin-yen Lin
Commit 2f7b1d8b5505 ("clk: mediatek: Do a runtime PM get on controllers during probe") enabled runtime PM for all mediatek clock controllers, but this introduced an issue on the resume path. If a device resumes earlier than the clock controller and calls clk_prepare() when runtime PM is enabled on the controller, it will end up calling clk_pm_runtime_get(). But the subsequent pm_runtime_resume_and_get() call will fail because the runtime PM is temporarily disabled during suspend. To workaround this, introduce a need_runtime_pm flag and only enable it on mt8183-mfgcfg, which is the driver that observed deadlock previously. Hopefully mt8183-cfgcfg won't run into the issue at the resume stage because the GPU should have stopped rendering before the system calls suspend.
