That substitution is\nwhat an RDS/TCP socket sending to a local address gets, and after it\nthe path init loop still runs for the TCP transport's RDS_MPATH_WORKERS\npaths and allocates an ordered workqueue for each, while\nrds_loop_conn_alloc() only ever provides transport data for path 0.\n\nrds_conn_destroy() sizes its teardown from c_trans, by then the\nloopback transport, so it visits path 0 only - and\nrds_conn_path_destroy() would skip the other paths anyway, since it\nreturns before destroy_workqueue() for a path without transport data.\nkfree(c_path) then drops the last pointers to seven workqueues.  That\nrepeats for every such connection, on every netns teardown or module\nunload, and every distinct local destination address is a separate\nconnection.\n\nRecompute npaths once the transport is final, so that creation and\ndestruction agree on the set of paths.  The c_path array stays sized\nfor the caller's transport; the unused entries are freed with it."}],"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":"4716af3897e95997d08183d351cece2dec9ee0c0","lessThan":"670f303169d2d36f315c40f6d3d18b5ee8498fea","status":"affected","versionType":"git"},{"version":"4716af3897e95997d08183d351cece2dec9ee0c0","lessThan":"ba3d1f480c7a3fba963e7867ad6cc557c197acbc","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":"7.0","status":"affected"},{"version":"0","lessThan":"7.0","status":"unaffected","versionType":"semver"},{"version":"7.2.9","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","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":"7.0","versionEndExcluding":"7.2.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/670f303169d2d36f315c40f6d3d18b5ee8498fea"},{"url":"https://git.kernel.org/stable/c/ba3d1f480c7a3fba963e7867ad6cc557c197acbc"}],"title":"net/rds: size a connection's path set by the transport it ends up with","x_generator":{"engine":"bippy-1.2.0"}}}}
