Per [1], -fsanitize=kernel-hwaddress with GCC currently does not disable instrumentation in functions with __attribute__((no_sanitize_address)). However, __attribute__((no_sanitize("hwaddress"))) does correctly disable instrumentation. Use it instead.

2024-10-23debugfs: add small file operations for most filesJohannes Berg
As struct file_operations is really big, but (most) debugfs files only use simple_open, read, write and perhaps seek, and don't need anything else, this wastes a lot of space for NULL pointers. Add a struct debugfs_short_fops and some bookkeeping code in debugfs so that users can use that with debugfs_create_file() using _Generic to figure out which function to use. Converting mac80211 to use it where possible saves quite a bit of space: 1010127 205064 1220 1216411 128f9b net/mac80211/mac80211.ko (before) 981199 205064 1220 1187483 121e9b net/mac80211/mac80211.ko (after) ------- -28928 = ~28KiB With a marginal space cost in debugfs: 8701 550 16 9267 2433 fs/debugfs/inode.o (before) 25233 325 32 25590 63f6 fs/debugfs/file.o (before) 8914 558 16 9488 2510 fs/debugfs/inode.o (after) 25380 325 32 25737 6489 fs/debugfs/file.o (after) --------------- +360 +8 (All on x86-64) A simple spatch suggests there are more than 300 instances, not even counting the ones hidden in macros like in mac80211, that could be trivially converted, for additional savings of about 240 bytes for each.

2024-10-23wifi: cfg80211: add option for vif allowed radiosFelix Fietkau
This allows users to prevent a vif from affecting radios other than the configured ones. This can be useful in cases where e.g. an AP is running on one radio, and triggering a scan on another radio should not disturb it. Changing the allowed radios list for a vif is supported, but only while it is down. While it is possible to achieve the same by always explicitly specifying a frequency list for scan requests and ensuring that the wrong channel/band is never accidentally set on an unrelated interface, this change makes multi-radio wiphy setups a lot easier to deal with for CLI users. By itself, this patch only enforces the radio mask for scanning requests and remain-on-channel. Follow-up changes build on this to limit configured frequencies.

2024-10-23wifi: mac80211: make bss_param_ch_cnt available for the low level driverEmmanuel Grumbach
Drivers may need to track this. Make it available for them, and maintain the value when beacons are received. When link X receives a beacon, iterate the RNR elements and update all the links with their respective data. Track the link id that updated the data so that each link can know whether the update came from its own beacon or from another link. In case, the update came from the link's own beacon, always update the updater link id. The purpose is to let the low level driver know if a link is losing its beacons. If link X is losing its beacons, it can still track the bss_param_ch_cnt and know where the update came from.

2024-10-22clk: Provide devm_clk_bulk_get_all_enabled() helperCristian Ciocaltea
Commit 265b07df758a ("clk: Provide managed helper to get and enable bulk clocks") added devm_clk_bulk_get_all_enable() function, but missed to return the number of clocks stored in the clk_bulk_data table referenced by the clks argument. Without knowing the number, it's not possible to iterate these clocks when needed, hence the argument is useless and could have been simply removed. Introduce devm_clk_bulk_get_all_enabled() variant, which is consistent with devm_clk_bulk_get_all() in terms of the returned value: > 0 if one or more clocks have been stored = 0 if there are no clocks < 0 if an error occurred Moreover, the naming is consistent with devm_clk_get_enabled(), i.e. use the past form of 'enable'. To reduce code duplication and improve patch readability, make devm_clk_bulk_get_all_enable() use the new helper, as suggested by Stephen Boyd.

2024-10-22seccomp: Stub for !HAVE_ARCH_SECCOMP_FILTERLinus Walleij
If we have CONFIG_SECCOMP but not CONFIG_HAVE_ARCH_SECCOMP_FILTER we get a compilation error: ../kernel/entry/common.c: In function 'syscall_trace_enter': ../kernel/entry/common.c:55:23: error: implicit declaration of function '__secure_computing' [-Werror=implicit-function-declaration] 55 | ret = __secure_computing(NULL); | ^~~~~~~~~~~~~~~~~~ This is because generic entry calls __secure_computing() unconditionally. Provide the needed stub similar to how current ARM does this by calling secure_computing_strict() in the absence of secure_computing(). This is similar to what is done for ARM in arch/arm/kernel/ptrace.c.

After a SED drive is provisioned, there is no way to change the SID password via the ioctl() interface. A new ioctl IOC_OPAL_SET_SID_PW will allow the password to be changed. The valid current password is required.

2024-10-22ublk: support device recovery without I/O queueingUday Shankar
ublk currently supports the following behaviors on ublk server exit: A: outstanding I/Os get errors, subsequently issued I/Os get errors B: outstanding I/Os get errors, subsequently issued I/Os queue C: outstanding I/Os get reissued, subsequently issued I/Os queue and the following behaviors for recovery of preexisting block devices by a future incarnation of the ublk server: 1: ublk devices stopped on ublk server exit (no recovery possible) 2: ublk devices are recoverable using start/end_recovery commands The userspace interface allows selection of combinations of these behaviors using flags specified at device creation time, namely: default behavior: A + 1 UBLK_F_USER_RECOVERY: B + 2 UBLK_F_USER_RECOVERY|UBLK_F_USER_RECOVERY_REISSUE: C + 2 The behavior A + 2 is currently unsupported. Add support for this behavior under the new flag combination UBLK_F_USER_RECOVERY|UBLK_F_USER_RECOVERY_FAIL_IO.

2024-10-22block: enable passthrough command statisticsKeith Busch
Applications using the passthrough interfaces for IO want to continue seeing the disk stats. These requests had been fenced off from this block layer feature. While the block layer doesn't necessarily know what a passthrough command does, we do know the data size and direction, which is enough to account for the command's stats. Since tracking these has the potential to produce unexpected results, the passthrough stats are locked behind a new queue flag that needs to be enabled with the /sys/block/<dev>/queue/iostats_passthrough attribute.

2024-10-22block: introduce add_disk_fwnode()Christian Marangi
Introduce add_disk_fwnode() as a replacement of device_add_disk() that permits to pass and attach a fwnode to disk dev. This variant can be useful for eMMC that might have the partition table for the disk defined in DT. A parser can later make use of the attached fwnode to parse the related table and init the hardcoded partition for the disk. device_add_disk() is converted to a simple wrapper of add_disk_fwnode() with the fwnode entry set as NULL.
