For example, the igb_io_error_detected\ntriggers the first call, and the igb_remove triggers the second call.\nThe second call to igb_down will block at napi_synchronize.\nHere's the call trace:\n

igb_io_error_detected detaches the network interface\nand requests a PCIE slot reset, however, the PCIE reset callback is\nnot being invoked and thus the Ethernet connection breaks down.\nAs the PCIE error in this case is a non-fatal one, requesting a\nslot reset can be avoided.\nThis patch fixes the task hung issue and preserves Ethernet\nconnection by ignoring non-fatal PCIE errors."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/igb/igb_main.c"],"versions":[{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"c2312e1d12b1c3ee4100c173131b102e2aed4d04","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"124e39a734cb90658b8f0dc110847bbfc6e33792","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"c9f56f3c7bc908caa772112d3ae71cdd5d18c257","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"994c2ceb70ea99264ccc6f09e6703ca267dad63c","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"fa92c463eba75dcedbd8d689ffdcb83293aaa0c3","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"39695e87d86f0e7d897fba1d2559f825aa20caeb","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"41f63b72a01c0e0ac59ab83fd2d921fcce0f602d","status":"affected","versionType":"git"},{"version":"9d5c824399dea881779d78a6c147288bf2dccb6b","lessThan":"004d25060c78fc31f66da0fa439c544dda1ac9d5","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/net/ethernet/intel/igb/igb_main.c"],"versions":[{"version":"2.6.25","status":"affected"},{"version":"0","lessThan":"2.6.25","status":"unaffected","versionType":"semver"},{"version":"4.14.322","lessThanOrEqual":"4.14.*","status":"unaffected","versionType":"semver"},{"version":"4.19.291","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.251","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.188","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.150","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.42","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.4.7","lessThanOrEqual":"6.4.*","status":"unaffected","versionType":"semver"},{"version":"6.5","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":"2.6.25","versionEndExcluding":"4.14.322"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"4.19.291"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"5.4.251"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"5.10.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"5.15.150"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"6.1.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"6.4.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.25","versionEndExcluding":"6.5"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c2312e1d12b1c3ee4100c173131b102e2aed4d04"},{"url":"https://git.kernel.org/stable/c/124e39a734cb90658b8f0dc110847bbfc6e33792"},{"url":"https://git.kernel.org/stable/c/c9f56f3c7bc908caa772112d3ae71cdd5d18c257"},{"url":"https://git.kernel.org/stable/c/994c2ceb70ea99264ccc6f09e6703ca267dad63c"},{"url":"https://git.kernel.org/stable/c/fa92c463eba75dcedbd8d689ffdcb83293aaa0c3"},{"url":"https://git.kernel.org/stable/c/39695e87d86f0e7d897fba1d2559f825aa20caeb"},{"url":"https://git.kernel.org/stable/c/41f63b72a01c0e0ac59ab83fd2d921fcce0f602d"},{"url":"https://git.kernel.org/stable/c/004d25060c78fc31f66da0fa439c544dda1ac9d5"}],"title":"igb:
