ifa_data member of every AF_LINK struct ifaddrs points at the
corresponding struct if_data. In ifconfig(8), do not try to suppress
duplicate AF_LINK ifaddrs by checking for a NULL ifa_data.
Don't copy out two AF_LINK struct ifaddrs for each active link-layer
address. getifaddrs(3) used to copy out one ifaddrs for the kernel's
RTM_IFINFO message, and one more for the kernel's RTM_NEWADDR message.
I suppress the first duplicate with a highly conservative change that
wastes a little bit of ifaddrs storage. The storage is not leaked.
numeric addresses. The documentation appears to say this works, and some
other systems support it -- more importantly, why should it _not_ work? If
it does not, getaddrinfo() cannot be used as a general-purpose textual to
binary address conversion utility function; yet it is the only such function
we have in the system, since inet_pton() requires a priori knowledge of the
address family.
This change also causes getaddrinfo() with NULL hint (expressly documented
as working) to work properly for numeric addresses.
NOTE: some of these will be changing in the future to be more
consistent with the technique used in the group & passwd backends.
I'm just documenting the existing behaviour.
Be more consistent when using certain terms.
Rename some variables to reduce confusion.
it possible to get the pid, euid and egid of the process at the remote
end at the time it did bind() or connect().
Add a new libc function, getpeereid() to easily get at the euid and egid.
As a consequence, bump libc's minor number.
Document the LOCAL_PEEREID socket option in unix(4).
Based on contribution by Arne H. Juul, minor modifications by myself.
_{files,dns,yp}_getenetbyaddr() functions from unsigned long to uint32_t.
In rev 1.29, getnetbyaddr(3) was changed to take uint32_t `net' argument
and also passisng uint32_t `net' to nsdispatch(3) varargs, but
these callback functions were not changed accordingly.
Patch was provided by christos, and this fixes amd(8) coredumps on alpha
when /etc/nsswitch.conf has more than one sources for netgroups.
