nmu isc-dhcp_4.4.1-2.1 . ANY . unstable . -m "recompile to fix double libdns-export.so linking"
Hi,
the #954736 was filled as result of dhcpd crash, because of double link against
libdns-export.so.1109 and libdns-export.so.1110:
(sid-amd64)root@calcifer:/home/ondrej# ldd /usr/sbin/dhcpd
linux-vdso.so.1 (0x00007ffe5236a000)
libeatmydata.so => /usr/lib/x86_64-linux-gnu/libeatmydata.so (0x00007efc93c96000)
libdns-export.so.1109 => /lib/x86_64-linux-gnu/libdns-export.so.1109 (0x00007efc93a64000)
^^^
libisc-export.so.1105 => /lib/x86_64-linux-gnu/libisc-export.so.1105 (0x00007efc939eb000)
libirs-export.so.161 => /lib/x86_64-linux-gnu/libirs-export.so.161 (0x00007efc939dd000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007efc9381a000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007efc93815000)
libcrypto.so.1.1 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 (0x00007efc93527000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007efc93506000)
libdns-export.so.1110 => /lib/x86_64-linux-gnu/libdns-export.so.1110 (0x00007efc932cb000)
^^^
libisccfg-export.so.163 => /lib/x86_64-linux-gnu/libisccfg-export.so.163 (0x00007efc9329c000)
/lib64/ld-linux-x86-64.so.2 (0x00007efc93da0000)
So, dhcpd links with libdns-export.so.1109, but libisccfg-export.so.163 links
with libdns-export.so.1110. The symbols in libdns-export.so are not versioned,
hence the crash, because dns_g_mctx gets initialized in one library, but the
symbol in other library gets used (and not initialized).
Before I come with better fix, could you please binNMU isc-dhcp?
Ondrej
