2025-01-17block: Don't trim an atomic writeJohn Garry
This is disallowed. This check will now be relevant since the device mapper personalities will start to support atomic writes, and they use this function.

2025-01-17block: Add common atomic writes enable flagJohn Garry
Currently only stacked devices need to explicitly enable atomic writes by setting BLK_FEAT_ATOMIC_WRITES_STACKED flag. This does not work well for device mapper stacking devices, as there many sets of limits are stacked and what is the 'bottom' and 'top' device can swapped. This means that BLK_FEAT_ATOMIC_WRITES_STACKED needs to be set for many queue limits, which is messy. Generalize enabling atomic writes enabling by ensuring that all devices must explicitly set a flag - that includes NVMe, SCSI sd, and md raid.

2025-01-17perf lock: Fix parse_lock_type which only retrieve one lock flagChun-Tse Shao
`parse_lock_type` can only add the first lock flag in `lock_type_table` given input `str`. For example, for `Y rwlock`, it only adds `rwlock:R` into this perf session. Another example is for `-Y mutex`, it only adds the mutex without `LCB_F_SPIN` flag. The patch fixes this issue, makes sure both `rwlock:R` and `rwlock:W` will be added with `-Y rwlock`, and so on.

2025-01-17landlock: Optimize file path walks and prepare for audit supportMickaël Salaün
Always synchronize access_masked_parent* with access_request_parent* according to allowed_parent*. This is required for audit support to be able to get back to the reason of denial. In a rename/link action, instead of always checking a rule two times for the same parent directory of the source and the destination files, only check it when an action on a child was not already allowed. This also enables us to keep consistent allowed_parent* status, which is required to get back to the reason of denial. For internal mount points, only upgrade allowed_parent* to true but do not wrongfully set both of them to false otherwise. This is also required to get back to the reason of denial. This does not impact the current behavior but slightly optimize code and prepare for audit support that needs to know the exact reason why an access was denied.

2025-01-17landlock: Align partial refer access checks with final onesMickaël Salaün
Fix a logical issue that could have been visible if the source or the destination of a rename/link action was allowed for either the source or the destination but not both. However, this logical bug is unreachable because either: - the rename/link action is allowed by the access rights tied to the same mount point (without relying on access rights in a parent mount point) and the access request is allowed (i.e. allow_parent1 and allow_parent2 are true in current_check_refer_path), - or a common rule in a parent mount point updates the access check for the source and the destination (cf. is_access_to_paths_allowed). See the following layout1.refer_part_mount_tree_is_allowed test that work with and without this fix. This fix does not impact current code but it is required for the audit support.

2025-01-17cpufreq: Use str_enable_disable()-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2025-01-17libbpf: Work around kernel inconsistently stripping '.llvm.' suffixAndrii Nakryiko
Some versions of kernel were stripping out '.llvm.<hash>' suffix from kerne symbols (produced by Clang LTO compilation) from function names reported in available_filter_functions, while kallsyms reported full original name. This confuses libbpf's multi-kprobe logic of finding all matching kernel functions for specified user glob pattern by joining available_filter_functions and kallsyms contents, because joining by full symbol name won't work for symbols containing '.llvm.<hash>' suffix. This was eventually fixed by [0] in the kernel, but we'd like to not regress multi-kprobe experience and add a work around for this bug on libbpf side, stripping kallsym's name if it matches user pattern and contains '.llvm.' suffix.
