2024-06-12bpf: selftests: Fix bpf_map_sum_elem_count() kfunc prototypeDaniel Xu
The prototype in progs/map_percpu_stats.c is not in line with how the actual kfuncs are defined in kernel/bpf/map_iter.c. This causes compilation errors when kfunc prototypes are generated from BTF. Fix by aligning with actual kfunc definitions.

With [0], pahole can now discover kfuncs and inject DECL_TAG into BTF. With this commit, we will start shipping said DECL_TAGs to downstream consumers if pahole supports it. This is useful for feature probing kfuncs as well as generating compilable prototypes. This is particularly important as kfuncs do not have stable ABI.

2024-06-12block: fix request.queuelist usage in flushChengming Zhou
Friedrich Weber reported a kernel crash problem and bisected to commit 81ada09cc25e ("blk-flush: reuse rq queuelist in flush state machine"). The root cause is that we use "list_move_tail(&rq->queuelist, pending)" in the PREFLUSH/POSTFLUSH sequences. But rq->queuelist.next == xxx since it's popped out from plug->cached_rq in __blk_mq_alloc_requests_batch(). We don't initialize its queuelist just for this first request, although the queuelist of all later popped requests will be initialized. Fix it by changing to use "list_add_tail(&rq->queuelist, pending)" so rq->queuelist doesn't need to be initialized. It should be ok since rq can't be on any list when PREFLUSH or POSTFLUSH, has no move actually. Please note the commit 81ada09cc25e ("blk-flush: reuse rq queuelist in flush state machine") also has another requirement that no drivers would touch rq->queuelist after blk_mq_end_request() since we will reuse it to add rq to the post-flush pending list in POSTFLUSH. If this is not true, we will have to revert that commit IMHO. This updated version adds "list_del_init(&rq->queuelist)" in flush rq callback since the dm layer may submit request of a weird invalid format (REQ_FSEQ_PREFLUSH | REQ_FSEQ_POSTFLUSH), which causes double list_add if without this "list_del_init(&rq->queuelist)". The weird invalid format problem should be fixed in dm layer.

2024-06-12block: Optimize disk zone resource cleanupDamien Le Moal
For zoned block devices using zone write plugging, an rcu_barrier() call is needed in disk_free_zone_resources() to synchronize freeing of zone write plugs and the destrution of the mempool used to allocate the plugs. The barrier call does slow down a little teardown of zoned block devices but should not affect teardown of regular block devices or zoned block devices that do not use zone write plugging (e.g. zoned DM devices that do not require zone append emulation). Modify disk_free_zone_resources() to return early if we do not have a mempool to start with, that is, if the device does not use zone write plugging. This avoids the costly rcu_barrier() and speeds up disk teardown.

(The variable netfs_debug was only used in #ifdef blocks for cpp vars that don't exist; Note that CONFIG_NETFS_DEBUG isn't settable via kconfig, a variable with that name never existed in the mainline and is probably just taken over (and renamed) from similar custom debug logging implementations.)

2024-06-12cpufreq: intel_pstate: Check turbo_is_disabled() in store_no_turbo()Rafael J. Wysocki
After recent changes in intel_pstate, global.turbo_disabled is only set at the initialization time and never changed. However, it turns out that on some systems the "turbo disabled" bit in MSR_IA32_MISC_ENABLE, the initial state of which is reflected by global.turbo_disabled, can be flipped later and there should be a way to take that into account (other than checking that MSR every time the driver runs which is costly and useless overhead on the vast majority of systems). For this purpose, notice that before the changes in question, store_no_turbo() contained a turbo_is_disabled() check that was used for updating global.turbo_disabled if the "turbo disabled" bit in MSR_IA32_MISC_ENABLE had been flipped and that functionality can be restored. Then, users will be able to reset global.turbo_disabled by writing 0 to no_turbo which used to work before on systems with flipping "turbo disabled" bit. This guarantees the driver state to remain in sync, but READ_ONCE() annotations need to be added in two places where global.turbo_disabled is accessed locklessly, so modify the driver to make that happen.

2024-06-12wifi: at76c50x: prefer struct_size over open coded arithmeticErick Archer
This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "cmd_buf" variable is a pointer to "struct at76_command" and this structure ends in a flexible array: struct at76_command { [...] u8 data[]; } __packed; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + count" in the kmalloc() function. Also, declare a new variable (total_size) since the return value of the struct_size() helper is used several times. At the same time, prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). In this case, it is important to note that the attribute used is "__counted_by_le" since the counter type is "__le16". This way, the code is more readable and safer.

2024-06-12wifi: iwlwifi: mvm: fix re-enabling EMLSRMiri Korenblit
When EMLSR gets unblocked, the current code checks if the last exit was due to an EXIT reason (as opposed to a BLOCKING one), and if so, it does nothing, as in this case a MLO scan was scheduled to run in 30 seconds. But the code doesn't consider the time that passed from the last exit, so if immediately after the exit a blocker occurred (e.g. non-BSS interface), and lasts for more than 30 seconds, then the MLO scan and the following link selection will decide not to enter EMLSR, and when the unblocking event finally happens, the reason is still set to the EXIT one, so it will do nothing, and we will not have the chance to re-enable EMLSR. Fix this by checking also the time that has passed since the last exit, only if it is less than 30 seconds, we can count on the scheduled MLO scan. Note that clearing the reason itself can't be done since it is needed for the EMLSR prevention mechanism.

This was needed when we had multiple types of transports. Now we only have pcie, so there is no need for this ops. Cleanup the code such as the different trans APIs will call the pcie function directly, instead of calling the callback, and remove struct iwl_trans_ops.

2024-06-12wifi: iwlwifi: pcie: integrate TX queue codeJohannes Berg
The TX queue code was mostly moved out to support an internal transport that we were never going to publish, but we're no longer using that. Since we're also going to be dissolving the virtual transport layer entirely, integrate the TX queue code into the PCIe layer. This also has a small kernel of already removing the virtual transport function layer, since iwl_trans_send_cmd() calls iwl_trans_pcie_send_hcmd() directly now, even if that still calls the transport send_cmd method for now, we'll clean it up later. Also, not everything is renamed yet.

This really isn't correct to be in the opmode, do the clamping (and power-of-2 fixup that may be necessary due to this, or even otherwise) in the queue code. Also move down the retrying of the allocation, it should be after all the size fixups, but also it just makes sense, and avoids retrying same-size allocations in the case of the BZ-family A-step workaround.

2024-06-12wifi: mac80211: fix erroneous errors for STA changesJohannes Berg
When e.g. wpa_supplicant sets only the MLD "sta" authorized state, the code actually applies that change, but then returns an error to userspace anyway because there were no changes to the link station, and no link ID was given. However, it's not incorrect to not have a link ID when wanting to change only the MLD peer ("sta") state, so the code shouldn't require it. To fix this, separate the "new_link" argument out into a new three-state enum, because if modify is called on a link STA only, it should return an error if no link is given or if it doesn't exist. For modify on the MLD "sta", not having a link ID is OK, but if there is one it should be validated. This seems to not have mattered much as wpa_supplicant just prints a message and continues, and the authorized state was already set before this error return. However, in the later code powersave recalculation etc. will be skipped, so that it may result in never allowing powersave on MLO connections.
