The recvmsg system calls for netlink sockets have been particularly prone to picking up unrelated data after a file descriptor race (where the descriptor is closed and reopened concurrently in a multi-threaded process, as the result of a file descriptor management issue elsewhere). This commit adds additional error checking and aborts the process if a datagram of unexpected length (without the netlink header) is received, or an error code which cannot happen due to the way the netlink socket is used. [BZ #12926] Terminate process on invalid netlink response. * sysdeps/unix/sysv/linux/netlinkaccess.h (__netlink_assert_response): Declare. * sysdeps/unix/sysv/linux/netlink_assert_response.c: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir) == inet] (sysdep_routines): Add netlink_assert_response. * sysdeps/unix/sysv/linux/check_native.c (__check_native): Call __netlink_assert_response. * sysdeps/unix/sysv/linux/check_pf.c (make_request): Likewise. * sysdeps/unix/sysv/linux/ifaddrs.c (__netlink_request): Likewise. * sysdeps/unix/sysv/linux/Versions (GLIBC_PRIVATE): Add __netlink_assert_response.
