Hi,
the regression has been introduced in 2.6.39.3 with commit
d0733d2e29b652b2e7b1438ececa732e4eed98eb. I experience this with a proprietary
binary program. So I cant give you the source code which fails. This program
used to work before but fails after applying this patch. As far as I understand
the programm is using this code for ipc communication. I have recorded the
strace output of the relevant part of the program.
strace without d0733d2e29b652b2e7b1438ececa732e4eed98eb on kernel 2.6.39.2
---------------
2056 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 4
2056 bind(4, {sa_family=AF_UNSPEC, sa_data="\0\0\0\0\0\0\0\0\0\0\0\0\0\0"},
16) = 0
2056 getsockname(4, {sa_family=AF_INET, sin_port=htons(33537),
sin_addr=inet_addr("0.0.0.0")}, [16]) = 0
2056 listen(4, 5) = 0
2056 setsockopt(4, SOL_TCP, TCP_NODELAY, [1], 4) = 0

6190 write(11, "ERROR: Failed to bind to interne"..., 66) = 66
6190 close(11) = 0
---------------
Btw, i have not enough knowledge on this topic to decide whether its the
programs fault or the kernels fault. The binary program is sybyl8.1 from
tripos.
Best regards, Rene
