[PATCH OLK-6.6] RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop
by Zhang Changzhong 18 Nov '24

18 Nov '24

From: Selvin Xavier <selvin.xavier(a)broadcom.com> mainline inclusion from mainline-v6.12-rc4 commit 8be3e5b0c96beeefe9d5486b96575d104d3e7d17 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2SU7 CVE: CVE-2024-50157 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Driver waits indefinitely for the fifo occupancy to go below a threshold as soon as the pacing interrupt is received. This can cause soft lockup on one of the processors, if the rate of DB is very high. Add a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th if the loop is taking more time. Pacing will be continuing until the occupancy is below the threshold. This is ensured by the checks in bnxt_re_pacing_timer_exp and further scheduling the work for pacing based on the fifo occupancy.
