[PATCH 3/3] ARM: dts: exynos: fix WM8960 clock name in Itop Elite

by Krzysztof Kozlowski

The WM8960 Linux driver expects the clock to be named "mclk". Otherwise the clock will be ignored and not prepared/enabled by the driver.

[PATCH] blk-crypto: make blk_crypto_evict_key() always try to evict

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Once all I/O using a blk_crypto_key has completed, filesystems can call blk_crypto_evict_key(). However, the block layer doesn't call blk_crypto_put_keyslot() until the request is being cleaned up, which happens after upper layers have been told (via bio_endio()) the I/O has completed. This causes a race condition where blk_crypto_evict_key() can see 'slot_refs > 0' without there being an actual bug. This makes __blk_crypto_evict_key() hit the 'WARN_ON_ONCE(atomic_read(&slot->slot_refs) != 0)' and return without doing anything, eventually causing a use-after-free in blk_crypto_reprogram_all_keys(). (This is a very rare bug and has only been seen when per-file keys are being used with fscrypt.) There are two options to fix this: either release the keyslot in blk_update_request() just before bio_endio() is called on the request's last bio, or just make __blk_crypto_evict_key() ignore slot_refs. Let's go with the latter solution for now, since it avoids adding overhead to the loop in blk_update_request(). (It does have the disadvantage that hypothetical bugs where a key is evicted while still in-use become harder to detect. But so far there haven't been any such bugs anyway.) A related issue with __blk_crypto_evict_key() is that ->keyslot_evict failing would cause the same use-after-free as well. Fix this by always removing the key from the keyslot management structures. Update the function documentation to properly document the semantics.

Unfortunately, scripts/tags.sh relies on such functionality to collect all_compiled_soures() leading to the following error: $ make COMPILED_SOURCE=1 tags GEN tags grep: \K is not allowed in lookarounds (but see PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK) The usage of \K for this pattern was introduced in commit 4f491bb6ea2a ("scripts/tags.sh: collect compiled source precisely") which speeds up the generation of tags significantly. In order to fix this issue without compromising the performance we can switch over to an equivalent sed expression. The same matching pattern is preserved here except \K is replaced with a backreference \1.
