However, the netdev lock has already been\nacquired before ndo_bpf is called because GVE supports queue management\nops. Calling the unlocked versions of napi_disable/enable results in a\ndeadlock when attempting to disable XSK pools, as the thread attempts to\nre-acquire a lock it already holds.\n\nUpdate the NAPI calls to use the locked versions.\n\nThis issue was found in production.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0cb6939a4dfefa822007b7a71986e06bc4f61f54","tags":[]},{"url":"https://git.kernel.org/stable/c/3d377911ce81fd4e61af814e750d8e08879a5208","tags":[]},{"url":"https://git.kernel.org/stable/c/42935a61001927aa01db10b53b420efd37eaa99b","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
