Subject: [PATCH] ping: Fix socket error reporting
There is actually no need for errno EAFNOSUPPORT special handling,
nor for any other errno. *All* errors needs to be reported on verbose
mode or when socket is required. If AF_INET6 socket is used with
disabled IPv6, error reporting is done by gai_strerror() (ipv6.disable=1)
or by connect() error handling in ping6_run() (EADDRNOTAVAIL on
net.ipv6.conf.all.disable_ipv6=1).
Bug was hidden because condition "errno == EAFNOSUPPORT && socktype ==
AF_INET6" introduced in d141cb6 was always false as AF_INET6 is is an address
family not a socket type, until otherwise correct fix 904cdb6. Attempt
to fix it in 79d713e introduced regression that other errors weren't
reported (e.g. EPERM on RAW socket on non-root, see #406).
Closes: https://github.com/iputils/iputils/pull/418
Fixes: https://github.com/iputils/iputils/issues/406
Fixes: 79d713e ("ping: Remove 'unsupported IPv6' warning on disabled IPv6")
Fixes: d141cb6 ("ping: work with older kernels that don't support ping sockets")
