Fix\nthis by:\n\nFirstly, make rxrpc_destroy_all_calls() only dump the first ten calls that\nare unexpectedly still on the list.  Limiting the number of steps means\nthere's no need to call cond_resched() or to remove calls from the list\nhere, thereby eliminating the need for rxrpc_put_call() to check for that.\n\nrxrpc_put_call() can then be fixed to unconditionally delete the call from\nthe list as it is the only place that the deletion occurs."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["include/trace/events/rxrpc.h","net/rxrpc/call_object.c"],"versions":[{"version":"2baec2c3f854d1f79c7bb28386484e144e864a14","lessThan":"93fc15be44a35b8e3c58d0238ac0d9b7c53465ff","status":"affected","versionType":"git"},{"version":"2baec2c3f854d1f79c7bb28386484e144e864a14","lessThan":"c63abf25203b50243fe228090526f9dbf37727bd","status":"affected","versionType":"git"},{"version":"2baec2c3f854d1f79c7bb28386484e144e864a14","lessThan":"3be718f659683ad89fad6f1eb66bee99727cae64","status":"affected","versionType":"git"},{"version":"2baec2c3f854d1f79c7bb28386484e144e864a14","lessThan":"ac5f54691be06a32246179d41be2d73598036deb","status":"affected","versionType":"git"},{"version":"2baec2c3f854d1f79c7bb28386484e144e864a14","lessThan":"146d4ab94cf129ee06cd467cb5c71368a6b5bad6","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["include/trace/events/rxrpc.h","net/rxrpc/call_object.c"],"versions":[{"version":"4.13","status":"affected"},{"version":"0","lessThan":"4.13","status":"unaffected","versionType":"semver"},{"version":"6.6.135","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.82","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.23","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.13","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","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":"4.13","versionEndExcluding":"6.6.135"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.12.82"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.18.23"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"6.19.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.13","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/93fc15be44a35b8e3c58d0238ac0d9b7c53465ff"},{"url":"https://git.kernel.org/stable/c/c63abf25203b50243fe228090526f9dbf37727bd"},{"url":"https://git.kernel.org/stable/c/3be718f659683ad89fad6f1eb66bee99727cae64"},{"url":"https://git.kernel.org/stable/c/ac5f54691be06a32246179d41be2d73598036deb"},{"url":"https://git.kernel.org/stable/c/146d4ab94cf129ee06cd467cb5c71368a6b5bad6"}],"title":"rxrpc: Fix call removal to use RCU safe deletion","x_generator":{"engine":"bippy-1.2.0"}}}}
