[BZ #966]
2005-06-13 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/clock_gettime.c (clock_gettime): Implement case where HANDLED_REALTIME is not defined. [BZ #966] 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. 2005-06-13 Thorsten Kukuk <kukuk@suse.de> * sysdeps/unix/sysv/linux/netinet/if_tr.h: Don't include kernel headers, instead copy important structs/defines. 2005-06-13 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (dl_main): Move DT_DEBUG setup before first _dl_debug_state call.
