This can cause soft lockup on\none of the processors, if the rate of DB is very high.\n\nAdd a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th\nif the loop is taking more time. Pacing will be continuing until the\noccupancy is below the threshold. This is ensured by the checks in\nbnxt_re_pacing_timer_exp and further scheduling the work for pacing based\non the fifo occupancy."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/infiniband/hw/bnxt_re/main.c"],"versions":[{"version":"2ad4e6303a6d7518632739eaf67821a3553db1bd","lessThan":"7998e7efd1d557af118ac96f48ebc569b929b555","status":"affected","versionType":"git"},{"version":"2ad4e6303a6d7518632739eaf67821a3553db1bd","lessThan":"2fb6b2e82413e401b72dfeacd7a60416fcfc5b41","status":"affected","versionType":"git"},{"version":"2ad4e6303a6d7518632739eaf67821a3553db1bd","lessThan":"8be3e5b0c96beeefe9d5486b96575d104d3e7d17","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/infiniband/hw/bnxt_re/main.c"],"versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","status":"unaffected","versionType":"semver"},{"version":"6.6.75","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.6","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"6.6.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"6.11.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/7998e7efd1d557af118ac96f48ebc569b929b555"},{"url":"https://git.kernel.org/stable/c/2fb6b2e82413e401b72dfeacd7a60416fcfc5b41"},{"url":"https://git.kernel.org/stable/c/8be3e5b0c96beeefe9d5486b96575d104d3e7d17"}],"title":"RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop","x_generator":{"engine":"bippy-1.2.0"}}}}
