Package: dnsmasq
Version: 2.45-1
Severity: important
If setcap() call at startup fail (for example, under
OpenVZ), dnsmasq reports an error and do not start:
# /etc/init.d/dnsmasq start
Starting DNS forwarder and DHCP server: dnsmasq
dnsmasq: setting capabilities failed: Operation not permitted
failed (warning).
failed!
#
in strace the error is:
capset(0x19980330, 0, {CAP_SETUID|CAP_NET_ADMIN|CAP_NET_RAW,
CAP_SETUID|CAP_NET_ADMIN|CAP_NET_RAW, CAP_SETUID|CAP_NET_ADMIN|CAP_NET_RAW}) =
-1 EPERM (Operation not permitted)
I think it should only warn about error and continue to
work. Different security solutions is quite popular and some
of them will not allow something that works on plain unix.
It's better to be tolerant to such failures.
I did not found how to fix it in configuration.
