Description Roland McGrath 2005-07-18 02:57:25 UTC 
This trunk patch should go into the 2.3 branch:

2005-06-13  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/netlinkaccess.h (__netlink_sendreq,
	__netlink_receive): Remove prototypes.
	(__netlink_request): New prototype.
	* sysdeps/unix/sysv/linux/ifaddrs.c: Include <alloca.h> and
	<stdint.h>.
	(__netlink_sendreq): Make static.
	(__netlink_receive): Rename to...
	(__netlink_request): ... this.  Add type argument, call
	__netlink_sendreq.  If MSG_TRUNC is set after recvmsg, retry
	with a bigger buffer.  Don't record buffers that contain no
	messages we are expecting.
	(getifaddrs): Use __netlink_request instead of __netlink_sendreq
	and __netlink_receive pairs.  Formatting.
	* sysdeps/unix/sysv/linux/if_index.c (if_nameindex_netlink): Use
	__netlink_request instead of __netlink_sendreq and __netlink_receive
	pair.

Comment 2 Roland McGrath 2005-07-19 03:30:52 UTC 
This fix is now in the 2.3 branch as well as the trunk, and the problem should
be resolved as of the 2.3.6 release.
