When i compile kernel with BPF_JIT=y and do echo 1 >  /proc/sys/net/core/bpf_jit_enable i'm getting "general protection fault" after a couple minutes of work.

E.g.

Comment 2 Marcin Mirosław 2012-01-18 13:31:32 UTC

I wrote version 3.1.7&3.1.8 because i tested them, i didn't try other version, probably they will be affected too.

Comment 3 Anthony Basile gentoo-dev

2012-02-04 01:58:03 UTC

Okay I'm cc-ing upstream on this one.  Can you test 3.2.2-r1 which is the latest stable.  You're probably right, but just in case something changed.

Comment 4 PaX Team 2012-02-04 13:40:45 UTC

also can you try a vanilla kernel please?

Comment 5 Marcin Mirosław 2012-02-04 22:20:38 UTC

On hardened 3.2.2-r1 i've started `tcpdump -i any -n` and i got: 2012-02-04T23:10:12.622385+01:00 meteor kernel: [  690.704833] __sk_free: optmem leakage (245768 bytes) detected.

On vanilla-3.2.2 i didn't reproduce problem yet (tcpdump didn't trigger problem).

Comment 6 PaX Team 2012-02-06 18:54:06 UTC

i managed to reproduce the problem (it's a double free of the work struct i added to the bpf jit code), the next patch will fix it.

Comment 7 Marcin Mirosław 2012-02-06 20:59:47 UTC

Good news, thanks.

Comment 8 Anthony Basile gentoo-dev

2012-02-14 10:09:28 UTC

Marcin did you verify any of the latest hardened-sources kernels to see that it was fixed?

Comment 9 Marcin Mirosław 2012-02-14 15:27:37 UTC

I didn't notice there is new hardened kernel. On 3.2.5-hardened i can't reproduce issue.
Thanks.
