Allowing scratch VMs through the ASID lookup also admits\ndma-fence mode VMs.\n\nIf such a VM faults on an already valid VMA, the handler reports success\nwithout fixing the fault, causing the GPU to retry indefinitely.\n\nOnly allow fault-mode VMs through the ASID lookup. Fault-mode VMs using\nscratch remain supported, while faults from 3D VMs are rejected.\n\n(cherry picked from commit bfb24a06405b652d37831f3fb66b71d33a6605de)"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/xe/xe_pagefault.c"],"versions":[{"version":"ad9843aac91a1eda12912a4922042ea04cfc29dc","lessThan":"905d648e97ef3a291f71a935a7fab0133f27f0f7","status":"affected","versionType":"git"},{"version":"ad9843aac91a1eda12912a4922042ea04cfc29dc","lessThan":"5e977521d21717edb8e91d004434697d6e3f248c","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/xe/xe_pagefault.c"],"versions":[{"version":"7.1","status":"affected"},{"version":"0","lessThan":"7.1","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","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":"7.1","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.1","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/905d648e97ef3a291f71a935a7fab0133f27f0f7"},{"url":"https://git.kernel.org/stable/c/5e977521d21717edb8e91d004434697d6e3f248c"}],"title":"drm/xe: Reject page faults from non-fault-mode scratch VMs","x_generator":{"engine":"bippy-1.2.0"}}}}
