Subject: iproute2 bug: please specify a netlink destination
Date: Fri, 30 May 2014 11:36:04 -0700 [thread overview]
Message-ID: <CALCETrUpynVUaWWOKf=ko3jYmTcTB9CH8tK0ton1uLuDvx1yzg@mail.gmail.com> (raw)
strace ip link says:
socket(PF_NETLINK, SOCK_RAW|SOCK_CLOEXEC, 0) = 3
setsockopt(3, SOL_SOCKET, SO_SNDBUF, [32768], 4) = 0
setsockopt(3, SOL_SOCKET, SO_RCVBUF, [1048576], 4) = 0
bind(3, {sa_family=AF_NETLINK, pid=0, groups=00000000}, 12) = 0
getsockname(3, {sa_family=AF_NETLINK, pid=3853, groups=00000000}, [12]) = 0
sendto(3, "(\0\0\0\22\0\1\3\351\316\210S\0\0\0\0\21\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
40, 0, NULL, 0) = 40
The fact that sendto doesn't return -ENOTCONN is a straight up bug,
and, of course, it's now unfixable. But please at least fix iproute2
to minimize future pain.
