Every other accessor of that word uses\natomic bitops, and some of them can run concurrently with the reset:\nRDS_LL_SEND_FULL is set from rds_send_xmit() and cleared from the\ntransport completion paths, neither of which holds anything that\nexcludes the shutdown worker.  A plain store racing an atomic\nread-modify-write on the same word is a data race, and whichever\nside loses has its update silently discarded.\n\nClear the two bits the reset is actually responsible for instead.\nRDS_IN_XMIT and RDS_RECV_REFILL need no store at all here: they\nbelong to the caller, rds_conn_shutdown(), which waits for both to be\nclear before calling the transport shutdown and this reset.\n\nThis also gives every bit in cp_flags a single well-defined writer\ndiscipline, which the following patches rely on when they turn\nRDS_IN_XMIT and RDS_RECV_REFILL into bit locks held across the\nteardown: a blanket store mid-teardown would destroy lock ownership\nthat an atomic clear preserves.\n\nOracle UEK carries the same conversion (\"net/rds: Preserve essential\nconnection state flags\"), motivated by its asynchronous shutdown\nstate machine, whose progress and destroy flags must survive the\nreset.  UEK's variant also clears RDS_IN_XMIT and RDS_RECV_REFILL\nbecause there the reset runs as the final step of a teardown that\nowns both bits, making those clears its unlock.  Upstream that\nrelease belongs in rds_conn_shutdown(): once a later patch in this\nseries turns the two bits into locks held across the teardown, ending\nownership needs release semantics and a wake-up that a plain clear\ninside the reset would not provide.\n\nBased on Oracle UEK commit \"net/rds: Preserve essential connection\nstate flags\" by Gerd Rausch."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/rds/connection.c"],"versions":[{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"c9a7c1eb0ad41dcf004a9e870e452cafedcd9172","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"b767b48614c38687d717082860de7aa46f3b142c","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"b7dc5da660eb5ffa7f7b4d33f2c74cb71c6edd6c","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"b8a8b6d25e7426a638c60eaba2129c0664131e84","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"ed3ee0ac4aafda50c2f4381eb973beefeb7879ac","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"6b8d7563c28b8112e6e54abe413b028ef3f8c549","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"cb62aa8f04655a4df487913949719c0a1266ed73","status":"affected","versionType":"git"},{"version":"00e0f34c616603ba6500f41943cbf89eb4a8a5be","lessThan":"103c4b13c4f50322910078d1c02f29334a574122","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/rds/connection.c"],"versions":[{"version":"2.6.30","status":"affected"},{"version":"0","lessThan":"2.6.30","status":"unaffected","versionType":"semver"},{"version":"5.10.271","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc2","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":"2.6.30","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"7.3-rc2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c9a7c1eb0ad41dcf004a9e870e452cafedcd9172"},{"url":"https://git.kernel.org/stable/c/b767b48614c38687d717082860de7aa46f3b142c"},{"url":"https://git.kernel.org/stable/c/b7dc5da660eb5ffa7f7b4d33f2c74cb71c6edd6c"},{"url":"https://git.kernel.org/stable/c/b8a8b6d25e7426a638c60eaba2129c0664131e84"},{"url":"https://git.kernel.org/stable/c/ed3ee0ac4aafda50c2f4381eb973beefeb7879ac"},{"url":"https://git.kernel.org/stable/c/6b8d7563c28b8112e6e54abe413b028ef3f8c549"},{"url":"https://git.kernel.org/stable/c/cb62aa8f04655a4df487913949719c0a1266ed73"},{"url":"https://git.kernel.org/stable/c/103c4b13c4f50322910078d1c02f29334a574122"}],"title":"net/rds: clear cp_flags bits individually in rds_conn_path_reset()","x_generator":{"engine":"bippy-1.2.0"}}}}
