[ospfd] Standardize buffer sizes used for displaying timers.
2005-11-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ospf_dump.h: Define OSPF_TIME_DUMP_SIZE as appropriate buffer size
for use with ospf_timer_dump and ospf_timeval_dump.
* ospf_vty.c: Change all buffer sizes used with ospf_timer_dump and
ospf_timeval_dump to have size OSPF_TIME_DUMP_SIZE.
(show_ip_ospf_interface_sub) Fix possible buffer overflow in
call to ospf_timer_dump.
