Sadly this is not fixed by the new kernel:

tanaris:~# ifup sit0
ioctl: No buffer space available
Failed to bring up sit0.

There is no kernel backtrace anymore, though.

The probably relevant part of the strace:

[pid  7685] arch_prctl(ARCH_SET_FS, 0x7f051f8d16e0) = 0
[pid  7685] mprotect(0x7f051f29c000, 12288, PROT_READ) = 0
[pid  7685] munmap(0x7f051f8d3000, 11893) = 0
[pid  7685] socket(PF_NETLINK, SOCK_RAW, 0) = 3
[pid  7685] setsockopt(3, SOL_SOCKET, SO_SNDBUF, [32768], 4) = 0
[pid  7685] setsockopt(3, SOL_SOCKET, SO_RCVBUF, [32768], 4) = 0
[pid  7685] bind(3, {sa_family=AF_NETLINK, pid=0, groups=00000000}, 12) = 0
[pid  7685] getsockname(3, {sa_family=AF_NETLINK, pid=7685, groups=00000000}, [18653764521033740]) = 0
[pid  7685] gettimeofday({1238875065, 527328}, NULL) = 0
[pid  7685] socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
[pid  7685] ioctl(4, 0x89f1, 0x7fff278da380) = -1 ENOBUFS (No buffer space available)

Kind regards,
Philipp Kern
