crypto: qce - fix uaf on qce_ahash_register_one

2022-01-27T07:47:33Z

[ Upstream commit b4cb4d31631912842eb7dce02b4350cbb7562d5e ] Pointer base points to sub field of tmpl, it is dereferenced after tmpl is freed. Fix this by accessing base before free tmpl.

crypto: qat - disregard spurious PFVF interrupts

2021-11-26T10:48:33Z

[ Upstream commit 18fcba469ba5359c1de7e3fb16f7b9e8cd1b8e02 ] Upon receiving a PFVF message, check if the interrupt bit is set in the message. If it is not, that means that the interrupt was probably triggered by a collision. In this case, disregard the message and re-enable the interrupts.

crypto: qat - detect PFVF collision after ACK

2021-11-26T10:48:33Z

[ Upstream commit 9b768e8a3909ac1ab39ed44a3933716da7761a6f ] Detect a PFVF collision between the local and the remote function by checking if the message on the PFVF CSR has been overwritten. This is done after the remote function confirms that the message has been received, by clearing the interrupt bit, or the maximum number of attempts (ADF_IOV_MSG_ACK_MAX_RETRY) to check the CSR has been exceeded.

These notifications are carried out through a message exchange using the PFVF protocol. Function names lead to believe they do perform init or shutdown logic.

crypto: qat - handle both source of interrupt in VF ISR

2021-09-22T09:42:58Z

[ Upstream commit 0a73c762e1eee33a5e5dc0e3488f1b7cd17249b3 ] The top half of the VF drivers handled only a source at the time. If an interrupt for PF2VF and bundle occurred at the same time, the ISR scheduled only the bottom half for PF2VF. This patch fixes the VF top half so that if both sources of interrupt trigger at the same time, both bottom halves are scheduled. This patch is based on earlier work done by Conor McLoughlin.
