Dominique Martinet 43bbadb7e4 net/9p: use a dedicated spinlock for trans_fd ... commit 296ab4a813 upstream. Shamelessly copying the explanation from Tetsuo Handa's 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 "struct p9_client"->lock 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's lock by a new one specific to the transport (client.c's protect the idr for fid/tag allocations, while trans_fd.c's protects its own req list and request status field that acts as the transport's state machine) Link: https://lore.kernel.org/r/20220904112928.1308799-1-asmadeus@codewreck.org Link: https://lkml.kernel.org/r/2470e028-9b05-2013-7198-1fdad071d999@I-love.SAKURA.ne.jp [1] Link: https://syzkaller.appspot.com/bug?extid=2f20b523930c32c160cc [2] Reported-by: syzbot <syzbot+2f20b523930c32c160cc@syzkaller.appspotmail.com> Reported-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Reviewed-by: Christian Schoenebeck <linux_oss@crudebyte.com> Signed-off-by: Dominique Martinet <asmadeus@codewreck.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2022-11-26 09:24:51 +01:00
