Hi,
I was debugging a segfault in the 'dmesg' utility that I finally
traced to the syslog syscall overflowing the buffer.
I'm under a 3.6.8 kernel and it has commit
e3756477aec028427fec767957c0d4b6cfb87208 present which apparently
fixed a similar issue, but I still have some occurence.
strace dmesg -s 8192
shows:
syslog(0x3, 0xb4e060, 0x2008) = 8259
so despite being given a buffer of 8200 bytes, it writes 8259 ...
It happens on several machines and this only seem to happen if there
was a wrap around in the log buffer (it's a first observation on a
limited number of sample so it might be a coincidence)
Cheers,
Sylvain
