Interesting. Can you please try the 1.2 package from devel? It has fixed quite a few issues already, and I should really backport it for older FC releases. ucarp-1.2-2.fc6 produces little different stacks: [root@localhost ~]# ucarp -v 1 -p password -s 192.168.40.17 -a 192.168.40.18 -i intel -k 64 -P [WARNING] Warning: no script called when going up [WARNING] Warning: no script called when going down [INFO] Local advertised ethernet address is [00:02:55:74:aa:dd] [WARNING] Switching to state: MASTER *** buffer overflow detected ***: ucarp terminated ======= Backtrace: ========= /lib/libc.so.6(__chk_fail+0x41)[0x314a61] ucarp[0x804d68d] ucarp[0x8049b4c] ucarp[0x804a1eb] ucarp[0x804a4db] ucarp[0x8049779] /lib/libc.so.6(__libc_start_main+0xdc)[0x24e214] ucarp[0x8049251] ======= Memory map: ======== 00235000-00366000 r-xp 00000000 fd:00 525581 /lib/libc-2.4.90.so 00366000-00368000 r-xp 00131000 fd:00 525581 /lib/libc-2.4.90.so 00368000-00369000 rwxp 00133000 fd:00 525581 /lib/libc-2.4.90.so 00369000-0036c000 rwxp 00369000 00:00 0 00577000-0059f000 r-xp 00000000 fd:00 437745 /usr/lib/libpcap.so.0.9.4 0059f000-005a0000 rwxp 00028000 fd:00 437745 /usr/lib/libpcap.so.0.9.4 006af000-006ba000 r-xp 00000000 fd:00 526993 /lib/libgcc_s-4.1.1-20060721.so.1 006ba000-006bb000 rwxp 0000a000 fd:00 526993 /lib/libgcc_s-4.1.1-20060721.so.1 00bed000-00c06000 r-xp 00000000 fd:00 524303 /lib/ld-2.4.90.so 00c06000-00c07000 r-xp 00018000 fd:00 524303 /lib/ld-2.4.90.so 00c07000-00c08000 rwxp 00019000 fd:00 524303 /lib/ld-2.4.90.so 08048000-0804f000 r-xp 00000000 fd:00 437760 /usr/sbin/ucarp 0804f000-08050000 rwxp 00007000 fd:00 437760 /usr/sbin/ucarp 0990c000-0992d000 rwxp 0990c000 00:00 0 b7d3e000-b7f3e000 r-xp 00000000 fd:00 436314 /usr/lib/locale/locale-archive b7f3e000-b7f40000 rwxp b7f3e000 00:00 0 b7f43000-b7f44000 rwxp b7f43000 00:00 0 b7f44000-b7f45000 r-xp b7f44000 00:00 0 [vdso] bff48000-bff5e000 rw-p bff48000 00:00 0 [stack] Aborted [root@localhost ~]# ucarp -v 1 -p password -s 192.168.40.17 -a 192.168.40.18 -i intel [WARNING] Warning: no script called when going up [WARNING] Warning: no script called when going down [INFO] Local advertised ethernet address is [00:02:55:74:aa:dd] [WARNING] Switching to state: BACKUP [WARNING] Switching to state: MASTER *** buffer overflow detected ***: ucarp terminated ======= Backtrace: ========= /lib/libc.so.6(__chk_fail+0x41)[0xb49a61] ucarp[0x804d68d] ucarp[0x8049b4c] ucarp[0x804a26f] ucarp[0x804a6be] ucarp[0x8049779] /lib/libc.so.6(__libc_start_main+0xdc)[0xa83214] ucarp[0x8049251] ======= Memory map: ======== 00859000-00864000 r-xp 00000000 fd:00 526993 /lib/libgcc_s-4.1.1-20060721.so.1 00864000-00865000 rwxp 0000a000 fd:00 526993 /lib/libgcc_s-4.1.1-20060721.so.1 00a6a000-00b9b000 r-xp 00000000 fd:00 525581 /lib/libc-2.4.90.so 00b9b000-00b9d000 r-xp 00131000 fd:00 525581 /lib/libc-2.4.90.so 00b9d000-00b9e000 rwxp 00133000 fd:00 525581 /lib/libc-2.4.90.so 00b9e000-00ba1000 rwxp 00b9e000 00:00 0 00c72000-00c8b000 r-xp 00000000 fd:00 524303 /lib/ld-2.4.90.so 00c8b000-00c8c000 r-xp 00018000 fd:00 524303 /lib/ld-2.4.90.so 00c8c000-00c8d000 rwxp 00019000 fd:00 524303 /lib/ld-2.4.90.so 00fba000-00fe2000 r-xp 00000000 fd:00 437745 /usr/lib/libpcap.so.0.9.4 00fe2000-00fe3000 rwxp 00028000 fd:00 437745 /usr/lib/libpcap.so.0.9.4 08048000-0804f000 r-xp 00000000 fd:00 437760 /usr/sbin/ucarp 0804f000-08050000 rwxp 00007000 fd:00 437760 /usr/sbin/ucarp 08561000-08582000 rwxp 08561000 00:00 0 b7de9000-b7fe9000 r-xp 00000000 fd:00 436314 /usr/lib/locale/locale-archive b7fe9000-b7feb000 rwxp b7fe9000 00:00 0 b7fee000-b7fef000 rwxp b7fee000 00:00 0 b7fef000-b7ff0000 r-xp b7fef000 00:00 0 [vdso] bfe0f000-bfe24000 rw-p bfe0f000 00:00 0 [stack] Aborted Then you might want to give the 1.3 snapshots are try too, and if the same problem is still present, report the bug upstream. The snapshot doesn't coredumps. At least for the first time... *** Bug 201596 has been marked as a duplicate of this bug. *** Fixed packages of 1.2, which include a patch to bring the code up to the 1.3 snapshot, have just been rebuilt for FC-4, FC-5 and devel. They should be pushed shortly. |
