  "description": "In the Linux kernel, the following vulnerability has been resolved:  net/9p: use a dedicated spinlock for trans_fd  Shamelessly copying the explanation from Tetsuo Handa\u0027s suggested patch[1] (slightly reworded): syzbot is reporting inconsistent lock state in p9_req_put()[2], for p9_tag_remove() from p9_req_put() from IRQ context is using spin_lock_irqsave() on \u0022struct p9_client\u0022-\u003Elock but trans_fd (not from IRQ context) is using spin_lock().  Since the locks actually protect different things in client.c and in trans_fd.c, just replace trans_fd.c\u0027s lock by a new one specific to the transport (client.c\u0027s protect the idr for fid/tag allocations, while trans_fd.c\u0027s protects its own req list and request status field that acts as the transport\u0027s state machine)",
