git busybox-git on OpenWrt / mips we see crashes when calling root@box:~ ip neigh show dev br-mastergate Segmentation fault
but this works: root@box:~ ip neigh show | grep 'br-mastergate' 192.168.100.111 dev br-mastergate lladdr e8:de:27:fb:ea:c9 used 0/0/0 probes 6 FAILED 192.168.2.104 dev br-mastergate lladdr 10:6f:3f:0e:31:8f used 0/0/0 probes 6 FAILED 10.35.50.168 dev br-mastergate lladdr 78:d6:f0:45:eb:55 used 0/0/0 probes 0 STALE 10.185.73.139 dev br-mastergate lladdr 78:d6:f0:45:eb:55 used 0/0/0 probes 0 STALE 169.254.123.93 dev br-mastergate lladdr 00:21:00:ce:c5:8f used 0/0/0 probes 0 STALE 192.168.178.37 dev br-mastergate lladdr c4:0a:cb:bc:04:70 used 0/0/0 probes 6 FAILED 192.168.23.75 dev br-mastergate lladdr 64:09:80:7a:e7:93 used 0/0/0 probes 6 FAILED 192.168.111.21 dev br-mastergate lladdr 64:70:02:d3:24:0b used 0/0/0 probes 6 FAILED 192.168.2.61 dev br-mastergate lladdr f4:ec:38:9d:86:36 ref 1 used 0/0/0 probes 4 INCOMPLETE fe80::7ad6:f0ff:fe45:eb55 dev br-mastergate lladdr 78:d6:f0:45:eb:55 used 0/0/0 probes 0 STALE also another 'real' interface (e.g. wlan1) works without issues, the 'br-mastergate' is a bridge. (_maybe_ this is the culprit) i dont see the problem in ipneigh_list_or_flush(), so here the output of gdb with 'bt full' shows this: bastian@buildserver:~/openwrt$ scripts/remote-gdb r48151.ar71xx.ip.23205.11.1452513596.core staging_dir/target-mips_34kc_musl-1.1.11/root-ar71xx/bin/busybox Using target mips_34kc (musl-1.1.11) Python Exception <type 'exceptions.ImportError'> No module named gdb: /home/bastian/openwrt/scripts/../staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_musl-1.1.11/bin/mips-openwrt-linux-gdb: warning: Could not load the Python gdb module from `/home/bastian/openwrt/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_musl-1.1.11/share/gdb/python'.
