I was able to narrow down the problem a bit more. It seems that the
"UCLIBC_SUPPORT_AI_ADDRCONFIG" is what causes the Segfaults/Core Dumps,
however, this option is only available if UCLIBC_USE_NETLINK is set.
Results: 0.9.30 (with 0.9.30 config, minus UCLIBC_SUPPORT_AI_ADDRCONFIG)
works fine for dropbear and samba.
> What is the impact of doing that?
I'm not really sure of the impact. From the uClibc-menuconfig help it
states following if they are helpful.
UCLIBC_USE_NETLINK:
¦
¦ In newer versions of Linux (2.4.17+), support was added for querying
¦ network device information via netlink rather than the old style
¦ ioctl's. Most of the time, the older ioctl style is sufficient (and
¦ it is smaller than netlink), but if you find that not all of your
¦ devices are being returned by the if_nameindex() function, you will
¦ have to use the netlink implementation.
¦
¦ Most people can safely answer N.
UCLIBC_SUPPORT_AI_ADDRCONFIG:
¦
¦ The implementation of AI_ADDRCONFIG is aligned with the glibc
¦ implementation using netlink to query interfaces to find both
¦ ipv4 and ipv6 support. This is only needed if an application uses
¦ the AI_ADDRCONFIG flag.
¦
¦ Most people can safely answer N.
