* crypto: qat - detect PFVF collision after ACKGiovanni Cabiddu2021-11-26
| | | | | | | | | | | | | | | | | [ 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.

* crypto: qat - do not ignore errors from enable_vf2pf_comms()Giovanni Cabiddu2021-09-22
| | | | | | | | | | | | | | | | [ Upstream commit 5147f0906d50a9d26f2b8698cd06b5680e9867ff ] The function adf_dev_init() ignores the error code reported by enable_vf2pf_comms(). If the latter fails, e.g. the VF is not compatible with the pf, then the load of the VF driver progresses. This patch changes adf_dev_init() so that the error code from enable_vf2pf_comms() is returned to the caller.

When there is problem allocating other list elements the list is unwound and freed. Then a check is made if the list head was allocated and is also freed. Keeping track of the what may need to be freed is the variable 'tail_old'. The unwinding/freeing block is while (tail_old) { mem_init = tail_old->next; kfree(tail_old); tail_old = mem_init; } The problem is that the first element of tail_old is also what was allocated for the list head init_header = kzalloc(sizeof(*init_header), GFP_KERNEL); ... *init_tab_base = init_header; flag = 1; } tail_old = init_header; So *init_tab_base/init_header are freed twice. There is another problem. When the input *init_tab_base is non null the tail_old is calculated by traveling down the list to first non null entry. tail_old = init_header; while (tail_old->next) tail_old = tail_old->next; When the unwinding free happens, the last entry of the input list will be freed. So the freeing needs a general changed. If locally allocated the first element of tail_old is freed, else it is skipped. As a bit of cleanup, reset *init_tab_base if it came in as null.
