Taking the lock again inside the DSA wrappers causes a deadlock.\n\nStumbled upon this when booting qemu with fbnic and CONFIG_NET_DSA_LOOP=y\n(which looks like some kind of testing device that auto-populates the ports\nof eth0). `ethtool -i` is enough to deadlock. This means we have basically zero\ncoverage for DSA stuff with real ops locked devs.\n\nRemove the redundant netdev_lock_ops()/netdev_unlock_ops() calls from\nthe DSA conduit ethtool wrappers."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/dsa/conduit.c"],"versions":[{"version":"2bcf4772e45adb00649a4e9cbff14b08a144f9e3","lessThan":"74d64ae4254e99ef8c8215b057a76edac82c5f99","status":"affected","versionType":"git"},{"version":"2bcf4772e45adb00649a4e9cbff14b08a144f9e3","lessThan":"abe91fd045874d21834482adcd7a9693e7377056","status":"affected","versionType":"git"},{"version":"2bcf4772e45adb00649a4e9cbff14b08a144f9e3","lessThan":"0f99e0c3e19badaf3fdced0d3feba623e59eed41","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/dsa/conduit.c"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.18.33","lessThanOrEqual":"6.18.*","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":"6.15","versionEndExcluding":"6.18.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.0.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/74d64ae4254e99ef8c8215b057a76edac82c5f99"},{"url":"https://git.kernel.org/stable/c/abe91fd045874d21834482adcd7a9693e7377056"},{"url":"https://git.kernel.org/stable/c/0f99e0c3e19badaf3fdced0d3feba623e59eed41"}],"title":"net: dsa: remove redundant netdev_lock_ops() from conduit ethtool ops","x_generator":{"engine":"bippy-1.2.0"}}}}
