The reviewed path\nkeeps aup->lock held across the MAC reset, queue stop and\nfree_irq(dev->irq, dev).\n\nA directed runtime validation kept that ndo_stop carrier and the same\nfree_irq(dev->irq, dev) operation under the driver lock. Lockdep reported\n\"BUG: sleeping function called from invalid context\" and \"Invalid wait\ncontext\" while free_irq() was taking desc->request_mutex, with\nau1000_close() and free_irq() on the stack.\n\nDrop aup->lock before freeing the IRQ. The protected close-time work still\nstops the device and queue before IRQ teardown, but the sleepable IRQ core\npath now runs outside the spinlocked section."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/amd/au1000_eth.c"],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"f86bca5b7857b85bfa8afdb4fa895d7c0a3f7ebc","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"26fd652915123a690f19d62b253b545a53f3cd51","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"d514b08ed61fdffe23604fd3e9e53c07cbe5ac3e","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"e1b5a13249975fec3cf654efa84f57118db2da2c","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"4536667fba8ddbaff2f2a135080ae6aabf737b5e","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"fc2233f1ab2a1ca562869bca6987d7477671388c","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"f48763beab4eea41fc480c9702ec6eebe8d75e4f","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/net/ethernet/amd/au1000_eth.c"],"versions":[{"version":"2.6.12","status":"affected"},{"version":"0","lessThan":"2.6.12","status":"unaffected","versionType":"semver"},{"version":"5.10.271","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"2.6.12","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f86bca5b7857b85bfa8afdb4fa895d7c0a3f7ebc"},{"url":"https://git.kernel.org/stable/c/26fd652915123a690f19d62b253b545a53f3cd51"},{"url":"https://git.kernel.org/stable/c/d514b08ed61fdffe23604fd3e9e53c07cbe5ac3e"},{"url":"https://git.kernel.org/stable/c/e1b5a13249975fec3cf654efa84f57118db2da2c"},{"url":"https://git.kernel.org/stable/c/4536667fba8ddbaff2f2a135080ae6aabf737b5e"},{"url":"https://git.kernel.org/stable/c/fc2233f1ab2a1ca562869bca6987d7477671388c"},{"url":"https://git.kernel.org/stable/c/f48763beab4eea41fc480c9702ec6eebe8d75e4f"}],"title":"net: au1000: move free_irq out of the close-time spinlocked section","x_generator":{"engine":"bippy-1.2.0"}}}}
