[PATCH v3 1/2] vsprintf: Add %p[mM]U for uppercase MAC address

by Konrad Gräfe

The CDC-ECM specification requires an USB gadget to send the host MAC address as uppercase hex string. This change adds the appropriate modifier.

[PATCH] wifi: ath10k: Serialize wake_tx_queue ops

by Alexander Wetzel

Serialize the ath10k implementation of the wake_tx_queue ops. ath10k_mac_op_wake_tx_queue() must not run concurrent since it's using ieee80211_txq_schedule_start(). Fixes: bb2edb733586 ("ath10k: migrate to mac80211 txq scheduling") Reported-by: Felix Fietkau <nbd(a)nbd.name> Link: https://lore.kernel.org/r/519b5bb9-8899-ae7c-4eff-f3116cdfdb56@nbd.name CC: <stable(a)vger.kernel.org> Signed-off-by: Alexander Wetzel <alexander(a)wetzel-home.de> --- The intend of this patch is to sort out an issue discovered in the discussion referred to by the Link tag. I can't test it with real HW and thus just implemented the per-ac queue lock Felix suggested. One obvious alternative to the per-ac lock would be to bring back the txqs_lock commit bb2edb733586 ("ath10k: migrate to mac80211 txq scheduling") dropped.

[PATCH v6 0/4] kexec: Fix kexec_file_load for llvm16 with PGO

by Ricardo Ribalda

When upreving llvm I realised that kexec stopped working on my test platform. The reason seems to be that due to PGO there are multiple .text sections on the purgatory, and kexec does not supports that.

[PATCH 1/1] page cache: fix page_cache_next/prev_miss off by one

by Mike Kravetz

Ackerley Tng reported an issue with hugetlbfs fallocate here[1]. The issue showed up after the conversion of hugetlb page cache lookup code to use page_cache_next_miss. Code in hugetlb fallocate, userfaultfd and GUP is now using page_cache_next_miss to determine if a page is present the page cache. The following statement is used. present = page_cache_next_miss(mapping, index, 1) != index; There are two issues with page_cache_next_miss when used in this way. 1) If the passed value for index is equal to the 'wrap-around' value, the same index will always be returned. This wrap-around value is 0, so 0 will be returned even if page is present at index 0. 2) If there is no gap in the range passed, the last index in the range will be returned. When passed a range of 1 as above, the passed index value will be returned even if the page is present. The end result is the statement above will NEVER indicate a page is present in the cache, even if it is. As noted by Ackerley in [1], users can see this by hugetlb fallocate incorrectly returning EEXIST if pages are already present in the file. In addition, hugetlb pages will not be included in core dumps if they need to be brought in via GUP. userfaultfd UFFDIO_COPY also uses this code and will not notice pages already present in the cache. It may try to allocate a new page and potentially return ENOMEM as opposed to EEXIST. Both page_cache_next_miss and page_cache_prev_miss have similar issues. Fix by: - Check for index equal to 'wrap-around' value and do not exit early. - If no gap is found in range, return index outside range. - Update function description to say 'wrap-around' value could be returned if passed as index.

[PATCH AUTOSEL 4.14 01/13] wifi: brcmfmac: pcie: Provide a buffer of random bytes to the device

by Sasha Levin

From: Hector Martin <marcan(a)marcan.st> [ Upstream commit 91918ce88d9fef408bb12c46a27c73d79b604c20 ] Newer Apple firmwares on chipsets without a hardware RNG require the host to provide a buffer of 256 random bytes to the device on initialization. This buffer is present immediately before NVRAM, suffixed by a footer containing a magic number and the buffer length. This won't affect chips/firmwares that do not use this feature, so do it unconditionally for all Apple platforms (those with an Apple OTP).

[PATCH AUTOSEL 5.4 01/18] wifi: brcmfmac: cfg80211: Pass the PMK in binary instead of hex

by Sasha Levin

From: Hector Martin <marcan(a)marcan.st> [ Upstream commit 89b89e52153fda2733562776c7c9d9d3ebf8dd6d ] Apparently the hex passphrase mechanism does not work on newer chips/firmware (e.g. BCM4387). It seems there was a simple way of passing it in binary all along, so use that and avoid the hexification. OpenBSD has been doing it like this from the beginning, so this should work on all chips. Also clear the structure before setting the PMK. This was leaking uninitialized stack contents to the device.
