I guess there was some error on the\nwireless link, which in turn caused an error condition for the smb\nfilesystem.\n\nIn the log, smb_file_read reports error\u003d4294966784 (0xfffffe00), which also\nshows up in the slab dumps, and also is -ERESTARTSYS. Error code 27499\ncorresponds to 0x6b6b, so the rq_errno field seems to be the only one being\nset after freeing the slab.\n\nIn smb_add_request (which is the only place in smbfs where I found\nERESTARTSYS), I found the following:\n\n if (!timeleft || signal_pending(current)) {\n /*\n * On timeout or on interrupt we want to try and remove the\n * request from the recvq/xmitq.\n */\n smb_lock_server(server);\n if (!(req-\u003erq_flags \u0026 SMB_REQ_RECEIVED)) {\n list_del_init(\u0026req-\u003erq_queue);\n smb_rput(req);\n }\n smb_unlock_server(server);\n }\n\t[...]\n if (signal_pending(current))\n req-\u003erq_errno \u003d -ERESTARTSYS;\n\nI guess that some codepath like smbiod_flush() caused the request to be\nremoved from the queue, and smb_rput(req) be called, without\nSMB_REQ_RECEIVED being set. This violates an asumption made by the quoted\ncode.\n\nThen, the above code calls smb_rput(req) again, the req gets freed, and\nreq-\u003erq_errno \u003d -ERESTARTSYS writes into the already freed slab. As\nlist_del_init doesn\u0027t cause an error if called multiple times, that does\ncause the observed behaviour (freed slab with rq_errno\u003d-ERESTARTSYS).\n\nIf this observation is correct, the following patch should fix it.\n\nI wonder why the smb code uses list_del_init everywhere - using list_del\ninstead would catch such situations by poisoning the next and prev\npointers.\n\nMay 4 23:29:21 knautsch kernel: [17180085.456000] ipw2200: Firmware error detected.
