Hello Greg, Can you please consider including the following patch in the stable linux-4.14.y branch? This is to fix a broken dependency for config option CONFIG_CIFS_POSIX 04f67ed3d83a ("cifs: allow disabling insecure dialects in the config") Following commit introduced a dependency for CONFIG_CIFS_POSIX on the config CONFIG_CIFS_ALLOW_INSECURE_LEGACY, but the above mentioned commit that had enable CONFIG_CIFS_POSIX in 4.14.94. ab9697222a1d ("cifs: In Kconfig CONFIG_CIFS_POSIX needs depends … [View More]

[PATCH 4.19] iwlwifi: mvm: Send LQ command as async when necessary

by Emmanuel Grumbach

From: Avraham Stern <avraham.stern(a)intel.com> commit 3baf7528d6f832b28622d1ddadd2e47f6c2b5e08 upstream. The parameter that indicated whether the LQ command should be sent as sync or async was removed, causing the LQ command to be sent as sync from interrupt context (e.g. from the RX path). This resulted in a kernel warning: "scheduling while atomic" and failing to send the LQ command, which ultimately leads to a queue hang. Fix it by adding back the required parameter to send the … [View More]command as sync only when it is allowed.

From: Eric Biggers <ebiggers(a)google.com> The arm64 NEON bit-sliced implementation of AES-CTR fails the improved skcipher tests because it sometimes produces the wrong ciphertext. The bug is that the final keystream block isn't returned from the assembly code when the number of non-final blocks is zero. This can happen if the input data ends a few bytes after a page boundary. In this case the last bytes get "encrypted" by XOR'ing them with uninitialized memory. Fix the assembly code … [View More]
