This looks like a false positive. I'll handle this. Miles, if you can easily reproduce could you try this?

With the previous kernel, I noticed that the INFO message would reliably occur after ten or fifteen minutes of booting. Today, I thought I would try suspend/resume before the INFO message appeared. This triggered a "possible circular locking dependency" warning, also related to the iwl3945 code. Should I open a separate bug report for this, or would you like me to put the new INFO message here? Please open a separate bug report, I'll mark as duplicate or so if applicable, but I doubt it, and then I would like the driver folks to take a look at it. Also, please attach the log snippet as a text file instead of pasting it so that it doesn't get line-wrapped.

New INFO text from kernel with different build options and patch applied.
Thanks, I'll take a closer look later. Seems my initial thought about the bug was wrong. Alright, I did -- in the first version of the trace this happens: A) cancel_timer_sync: local_irq_save() lock_map_acquire(fake timer lock) B) run_softirq: lock_map_acquire(fake timer lock) And due to dependencies with priv->lock we get into the ordering issue. In the second version, we have this: A) cancel_timer_sync: local_irq_save() lock_map_acquire(fake timer lock) B) run_softirq: local_irq_disable() lock_map_acquire(fake timer lock) local_irq_enable() and we get bitten by trace_hardirqs_on() (called from local_irq_enable) which actually marks the currently held locks, which most definitely is correct but we thought we could trick it. I see one other option, but that needs a few more thoughts first. Scratch that other option. Miles, are you running exactly mainline? The report isn't making sense wrt. the code in drivers/net/wireless/iwlwifi/iwl3945-base.c, maybe you could attach that file here? Created attachment 21231 [details]
Requested source code
Hmm. I only have the patch you sent earlier applied onto 2.6.30-rc4-git1.
Thanks. I think I've got it. But some preliminary info first.
the second lock's dependencies:
-> (&priv->lock){-.-...} <key>
-> (pci_lock){......} ops: 9888 {
-> (pci_config_lock){......} ops: 9990 {
-> (&rxq->lock){..-...} ops: 30981 {
-> (&n->list_lock){..-...} ops: 439192 {
-> (&zone->lock){..-...} ops: 50454 {
-> (&base->lock){-.-...} ops: 526346 {
-> (&q->lock){-.-.-.} ops: 4928318 {
-> (&rq->lock){-.-.-.} ops: 2158037 {
-> (&vec->lock){-.-...} ops: 4344 {
-> (&rt_b->rt_runtime_lock){-.-...} ops: 482 {
-> (&cpu_base->lock){-.-...} ops: 1793557 {
-> (&rt_rq->rt_runtime_lock){-.-...} ops: 2710 {
-> (&sig->cputimer.lock){-.-...} ops: 20901 {
-> (&rq->lock/1){..-...} ops: 2084 {
-> (&ep->lock){..-...} ops: 103 {

-> (&list->lock#6){..-...} ops: 32394 {
-> (&(&priv->scan_check)->timer){+.-...} ops: 19 {
Now, the normal irq deadlock scenario with just two locks (I hope it won't wrap): phase CPU 1 CPU 2 --------------------------------------------- somewhere lock-irq(A) lock(B) unlock(B) unlock(A) state change lock(B) unlock(B) irq handler lock(A) unlock(A) deadlock lock-irq(A) lock(B) IRQ -----> lock(A) lock(B) Let's try that again
phase CPU 1 CPU 2
-------------------------------------
somewhere
lock-irq(A)
lock(B)
unlock(B)
unlock(A)
state change
lock(B)
unlock(B)
irq handler
lock(A)
unlock(A)
deadlock
lock-irq(A)
lock(B)
IRQ -----> lock(A)
lock(B)
Now, with timer instead of lock B. Feel free to ignore "lock" and "unlock" bits, they are just how lockdep knows about this, not a real lock.
A - lock
T - timer
phase CPU 1 CPU 2
---------------------------------------------
some place that calls
cancel_timer_sync()
(which is the | code)
lock-irq(A)
| "lock-irq"(T)
| "unlock"(T)
| wait(T)
unlock(A)
timer softirq
"lock"(T)
run(T)
"unlock"(T)
irq handler
lock(A)
unlock(A)
Now all that again, interleaved, leading to deadlock:
lock-irq(A)
"lock"(T)
run(T)
IRQ during or maybe
before run(T) --> lock(A)
"lock-irq"(T)
wait(T)
What does it all mean?
Bottom line is: you can never use cancel_timer_sync (or cancel_delayed_work[_sync] for that matter) within a spin_lock_irqsave() section! Why? Because an interrupt could come in there after spin_lock_irqsave(A) and while run(T) on CPU 1 and do spin_lock(A), but CPU 2 in this picture can never finish the critical section locked with A because it's waiting for T.
As such, it is a bug in iwl3945 after all.
Ah, I see the problem.
iwl-scan.c:
priv->rx_handlers[SCAN_COMPLETE_NOTIFICATION] =
iwl_rx_scan_complete_notif;
iwl_rx_scan_complete_notif:
cancel_delayed_work(&priv->scan_check);
iwl_irq_tasklet:
spin_lock_irqsave(&priv->lock, flags);
...
iwl_rx_handle
...
iwl_rx_handle:
...
priv->rx_handlers[pkt->hdr.cmd] (priv, rxb);
...
The bug gets only reported by lockdep once the timer fires though.

do not cancel delayed work in interrupt context
Miles,
Could you please test this patch?
Thank you
Looks good here. Thanks! Hmm. Did this patch make it into the Linus tree? I just hit this again in 2.6.30-rc6-git1. I will attach the stack trace. Created attachment 21383 [details]
dmesg output
Miles, the patch was posted to linux-wireless on 15 May. I'll try to get it queued to Linus shortly. This patch can be found in Linus's 2.6.30-rc8. Can this bug be closed now? Thanks |
