| |
I've noticed that old versions of traceroute no longer work properly with the latest kernel. 2.6.13.4 is OK. I've done a bit of strace and am posting the differences here. These are from a 64 bit kernel using traceroute 0.6.2 as shipped with most versions of SuSE. I have confirmed that the same problem is present in a 32 bit kernel on a different machine. A later traceroute 1.4a12 works properly.
2.6.13.4
poll([{fd=6, events=POLLERR, revents=POLLERR}, {fd=3, events=POLLERR}, {fd=4, events=POLLERR}, {fd=5, events=POLLERR}], 4, 1) = 1 recvmsg(6, {msg_name(16)={sa_family=AF_INET, sin_port=htons(33443), sin_addr=inet_addr("69.10.132.115")}, msg_iov(0)=[], msg_controllen=80, {cmsg_len=32, cmsg_level=SOL_SOCKET, cmsg_type=0x1d /* SCM_??? */, ...}, msg_flags=MSG_ERRQUEUE}, MSG_ERRQUEUE) = 0
2.6.14 poll([{fd=3, events=POLLERR, revents=POLLERR}, {fd=4, events=POLLERR}, {fd=5, events=POLLERR}, {fd=6, events=POLLERR}, {fd=7, events=POLLERR}, {fd=8, events=POLLERR}], 6, 1) = 1 recvmsg(3, 0x7fffffa30960, MSG_ERRQUEUE) = -1 EAGAIN (Resource temporarily unavailable) .... .... poll([{fd=3, events=POLLERR, revents=POLLERR}, {fd=4, events=POLLERR, revents=POLLERR}, {fd=5, events=POLLERR}, {fd=6, events=POLLERR}, {fd=7, events=POLLERR}, {fd=8, events=POLLERR}, {fd=9, events=POLLERR}], 7, 1) = 2 recvmsg(3, 0x7fffffa30960, MSG_ERRQUEUE) = -1 EAGAIN (Resource temporarily unavailable) recvmsg(4, 0x7fffffa30960, MSG_ERRQUEUE) = -1 EFAULT (Bad address)
I'm up for more diagnostics if necessary.
Cheers David
