@RLH Sorry. This is a panic that a user reported to me. We tried to reproduce it but failed. And it seems to happen very infrequently.

I suspect this is a go runtime bug. If you think this is a user program bug, I can try to check the related code.

Also I am happy to look into the related code inside go if you are sure this is a go runtime issue.

Let me know if you want more information.

If this is coming from the kernel, there will be a report in dmesg (there is on arm64 systems)

The code is interesting. Normally, it should 0x1 (SEGV_MAPERR).
(The other possibilities are 2 for SEGV_ACCERR, and 3 for
SEGV_BNDERR)

code 0x80 just signifies that it's coming from kernel, but doesn't
give a reason for the signal.

And looking at the code:
609 if v.ptr() == nil {
610 systemstack(func() {
611 mCache_Refill(c, int32(sizeclass))
612 })
613 shouldhelpgc = true
614 s = c.alloc[sizeclass]
615 v = s.freelist
616 }
617 s.freelist = v.ptr().next

v.ptr() shouldn't be nil at line 617 unless someone else is also
modifying it. (but it's from gomcache, nobody else should be
modifying it concurrently.

Could you tell us more about the program? Does it use cgo or
unsafe? Have you tried to run it with race detector enabled?

The program is etcd (https://github.com/coreos/etcd). The core part of etcd does not involve cgo/unsafe, but we are using external pkgs. So I am not sure.

Have you tried to run it with race detector enabled?

A normal go user program can corrupt runtime data? Or the race detector can detect data race in cgo? I cannot reproduce the issue myself right now. I do not know if it helps to collect data by enabling race detector.

A program with a data race is undefined, it can do anything including corrupting runtime data structures.

@xiang90 i had a quick play with coreos/etcd and found several packages fail the race detector. Are these know failures ? I think you should address those in coreos/etcd before we can investigate.

@lorenz, can you post your panic message and traceback?

Is in coreos/etcd#3745.

Ah, sorry, I hadn't realized you were the poster of the original bug.

I'm inclined to agree with @davecheney that there's not much we can do until the races are fixed.

RLH commented Oct 26, 2015

I agree with Austin and Dave that this should be closed until the program
passes the race detector. That said I am sympathetic to Xlang's
expectations that the runtime needs to be more robust against racy code.
There is a history of C malloc implementations pulling their free lists
from the heap and building them outside of the heap to avoid triggering
heap corruption bugs. Obviously racy programs will always be a problem and
we won't be able to completely insulate the runtime from them. Long term we
are headed in this direction.

@RLH

After reading runtime malloc code, I agree with @davecheney that the user code can potentially corrupt runtime heap. But to be honest, I still feel the possibility is still too low that a newly allocated freelist is corrupted.

I would like to close this issue on go upstream for now. I will reopen it if I find something.

@davecheney Just want to make sure we are fixing the current thing (at least fixing what you have seen)

i had a quick play with coreos/etcd and found several packages fail the race detector.

How did you play with coreos/etcd? How did you find out the races?
