  "message": "char: remove watch callback on chardev detach from frontend\n\nIf a frontend device releases the chardev (via unplug), the chr handlers\nare set to NULL via qdev\u0027s exit callbacks invoking\nqemu_chr_add_handlers().  If the chardev had a pending operation, a\ncallback will be invoked, which will try to access data in the\njust-released frontend, causing a segfault.\n\nEnsure the callbacks are disabled when frontends release chardevs.\n\nThis was seen when a virtio-serial port was unplugged when heavy\nguest-\u003ehost IO was in progress (causing a callback to be registered).\nIn the window in which the throttling was active, unplugging ports\ncaused a qemu segfault.\n\nhttps://bugzilla.redhat.com/show_bug.cgi?id\u003d985205\n\nCC: \u003cqemu-stable@nongnu.org\u003e\nReported-by: Sibiao Luo \u003csluo@redhat.com\u003e\nReviewed-by: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\nSigned-off-by: Amit Shah \u003camit.shah@redhat.com\u003e\n",
