I have been trying to understand the failure better:
(kgdb) frame 10
#10 0xffffffff80473265 in usb_transfer_complete (xfer=0xffffff00045cbc00)
at /red/public/freebsd/sources/stable/sys/dev/usb/usbdi.c:949
949 STAILQ_REMOVE_HEAD(&pipe->queue, next);
(kgdb) list
944 #ifdef DIAGNOSTIC
945 xfer->busy_free = XFER_BUSY;
946 #endif
947 KASSERT(STAILQ_FIRST(&pipe->queue) == xfer,
948 ("usb_transfer_complete: bad dequeue"));
949 STAILQ_REMOVE_HEAD(&pipe->queue, next);
950 }
951 DPRINTFN(5,("usb_transfer_complete: repeat=%d new head=%p\n",
952 repeat, STAILQ_FIRST(&pipe->queue)));
For reference:
#define STAILQ_NEXT(elm, field) ((elm)->field.stqe_next)
#define STAILQ_FIRST(head) ((head)->stqh_first)
#define STAILQ_REMOVE_HEAD(head, field) do { \
if ((STAILQ_FIRST((head)) = \
STAILQ_NEXT(STAILQ_FIRST((head)), field)) == NULL) \
(head)->stqh_last = &STAILQ_FIRST((head)); \
} while (0)
Looking at the data:
(kgdb) p *pipe
$15 = {iface = 0x0, device = 0xffffff009c1e4a00, endpoint =
0xffffff009c1e4a38, refcnt = 1, running = 0 '\0', aborting = 0 '\0',
queue = {stqh_first = 0x0, stqh_last = 0xffffff000c8576a0}, next = {le_next
= 0x806b560b4, le_prev = 0x0}, intrxfer = 0x0,
repeat = 0 '\0', interval = -1, methods = 0xffffffff80a6e340}
(kgdb) p pipe->queue
$16 = {stqh_first = 0x0, stqh_last = 0xffffff000c8576a0}
(kgdb) p pipe->queue->stqh_first
$17 = (struct usbd_xfer *) 0x0
And, of course,
(kgdb) p pipe->queue->stqh_first.next
Cannot access memory at address 0x290
If the kernel had been built with INVARIANTS, presumably the prior assertion
would have been triggered. It is not clear to me how the transfer ended up
in this bad state. Could the "USBD_NOMEM" status be a clue?
(kgdb) p *xfer
$6 = {pipe = 0xffffff000c857680, priv = 0x0, buffer = 0xfffffffef5b69ff0,
length = 18, actlen = 0, flags = 6, timeout = 5000,
status = USBD_NOMEM, callback = 0, done = 1 '\001', request = {bmRequestType
= 128 '\200', bRequest = 6 '\006',
wValue = "\001\003", wIndex = "\t\004", wLength = "\022"}, frlengths =
0x0, nframes = 0, device = 0xffffff009c1e4a00, dmamap = {
segs = {{ds_addr = 23408640, ds_len = 16}, {ds_addr = 23355392, ds_len =
2}, {ds_addr = 0, ds_len = 0} <repeats 31 times>},
nsegs = 2, map = 0xffffff000cbf5e00}, allocbuf = 0x0, rqflags = 1, next =
{stqe_next = 0x0}, hcpriv = 0x0, timeout_handle = {
c_links = {sle = {sle_next = 0x0}, tqe = {tqe_next = 0x0, tqe_prev =
0x0}}, c_time = 0, c_arg = 0x0, c_func = 0,
c_mtx = 0xffffffff80b12600, c_flags = 0}}
I am getting out of my depth. I will spend some more time trying to learn
this code but would appreciate pointers.
Cheers,
