[PATCH openEuler-1.0-LTS] crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY
by Yi Yang 27 Nov '24

27 Nov '24

mainline inclusion from mainline-v6.13-rc1 commit 662f2f13e66d3883b9238b0b96b17886179e60e2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7RZMT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for PADATA_RESET"), the pcrypt encryption and decryption operations return -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1. Fix this issue by calling crypto layer directly without parallelization in that case.
