  "message": "net/packet: fix a race in packet_set_ring() and packet_notifier()\n\nupstream commit: 01d3c8417b9c1b884a8a981a3b886da556512f36\n\nWhen packet_set_ring() releases po-\u003ebind_lock, another thread can\nrun packet_notifier() and process an NETDEV_UP event.\n\nThis race and the fix are both similar to that of commit 15fe076edea7\n(\"net/packet: fix a race in packet_bind() and packet_notifier()\").\n\nThere too the packet_notifier NETDEV_UP event managed to run while a\npo-\u003ebind_lock critical section had to be temporarily released. And\nthe fix was similarly to temporarily set po-\u003enum to zero to keep\nthe socket unhooked until the lock is retaken.\n\nThe po-\u003ebind_lock in packet_set_ring and packet_notifier precede the\nintroduction of git history.\n\nBUG\u003db/438677841\nTEST\u003dpresubmit\nRELEASE_NOTE\u003dFixed KCTF-01d3c84 in the Linux kernel.\n\ncos-patch: security-high\nFixes: 1da177e4c3f4 (\"Linux-2.6.12-rc2\")\nCc: stable@vger.kernel.org\nChange-Id: I7efa71cc24262d1658ab2669798793eb5954ad2c\nSigned-off-by: Quang Le \u003cquanglex97@gmail.com\u003e\nSigned-off-by: Willem de Bruijn \u003cwillemb@google.com\u003e\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\nReviewed-on: https://cos-review.googlesource.com/c/third_party/kernel/+/109090\nTested-by: Cusky Presubmit Bot \u003cpresubmit@cos-infra-prod.iam.gserviceaccount.com\u003e\nReviewed-by: Kevin Berry \u003ckpberry@google.com\u003e\nMain-Branch-Verified: Cusky Presubmit Bot \u003cpresubmit@cos-infra-prod.iam.gserviceaccount.com\u003e\nReviewed-on: https://cos-review.googlesource.com/c/third_party/kernel/+/109096\n",
