The next list_for_each_entry_continue() from\nthe hitch finds the same resource again, causing an infinite loop.\n\nFix by deferring del_bulk_move to the success path only.\n\nOn the success path, TTM_TT_FLAG_SWAPPED has just been set by\nttm_tt_swapout() but the resource is still tracked in the bulk_move range,\nso ttm_resource_del_bulk_move()'s !ttm_resource_unevictable() guard would\nincorrectly skip the removal. Introduce\nttm_resource_del_bulk_move_unevictable() which bypasses that guard."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/ttm/ttm_bo.c","drivers/gpu/drm/ttm/ttm_resource.c","include/drm/ttm/ttm_resource.h"],"versions":[{"version":"fc5d96670eb2540d2572a14351e82ffe45d5ac11","lessThan":"0124a09e3e5f5f6080efe9663b27af27933f8382","status":"affected","versionType":"git"},{"version":"fc5d96670eb2540d2572a14351e82ffe45d5ac11","lessThan":"b2ed01e7ad3de80333e9b962a44024b094bc0b2b","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/gpu/drm/ttm/ttm_bo.c","drivers/gpu/drm/ttm/ttm_resource.c","include/drm/ttm/ttm_resource.h"],"versions":[{"version":"6.13","status":"affected"},{"version":"0","lessThan":"6.13","status":"unaffected","versionType":"semver"},{"version":"7.0.10","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"6.13","versionEndExcluding":"7.0.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0124a09e3e5f5f6080efe9663b27af27933f8382"},{"url":"https://git.kernel.org/stable/c/b2ed01e7ad3de80333e9b962a44024b094bc0b2b"}],"title":"drm/ttm: Fix ttm_bo_swapout() infinite LRU walk on swapout failure","x_generator":{"engine":"bippy-1.2.0"}}}}
