I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master
from `freeaddrinfo'.
`getifaddrs' and `freeifaddrs' are not in POSIX, they should not be
exposed along `freeaddrinfo' (through `__check_pf') which is POSIX.
* include/ifaddrs.h (__getifaddrs, __freeifaddrs): New declarations,
and use libc_hidden_def on them.
* inet/ifaddrs.c (__getifaddrs, __freeifaddrs): Use libc_hidden_def on
them.
* sysdeps/gnu/ifaddrs.c (__getifaddrs, __freeifaddrs): Likewise.
* inet/check_pf.c (__check_pf): Use __getifaddrs and __freeifaddrs
instead of getifaddrs and freeifaddrs.
Various objects in glibc bring in ifaddrs.o (via references to
__netlink_*) and thereby getifaddrs and freeifaddrs, which are not
part of any standard supported by glibc. These should be weak aliases
of __getifaddrs and __freeifaddrs; this patch makes them so.
(The path by which these functions are brought in is Linux-specific,
but it seems less confusing to make all versions of these functions
weak aliases rather than only the Linux-specific versions that
definitely need it.)
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by this patch).
[BZ #17668]
* inet/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define
as weak alias of __getifaddrs. Use libc_hidden_weak.
(freeifaddrs): Rename to __freeifaddrs and define as weak alias of
__freeifaddrs. Use libc_hidden_weak.
* sysdeps/gnu/ifaddrs.c (getifaddrs): Rename to __getifaddrs and
define as weak alias of __getifaddrs. Use libc_hidden_weak.
(freeifaddrs): Rename to __freeifaddrs and define as weak alias of
__freeifaddrs. Use libc_hidden_weak.
* sysdeps/unix/sysv/linux/ifaddrs.c (getifaddrs): Rename to
__getifaddrs and define as weak alias of __getifaddrs. Use
libc_hidden_weak.
(freeifaddrs): Rename to __freeifaddrs and define as weak alias of
__freeifaddrs. Use libc_hidden_weak.
* conform/Makefile (test-xfail-XOPEN2K/net/if.h/linknamespace):
Remove variable.
(test-xfail-POSIX2008/net/if.h/linknamespace): Likewise.
(test-xfail-XOPEN2K8/net/if.h/linknamespace): Likewise.
Grok AF_LINK if defined.
From Momchil Velikov <velco@fadata.bg>.
* sysdeps/gnu/ifaddrs.c (getifaddrs): If ioctl fails for netmask,
brdaddr, or dstaddr, just set those pointers to null and don't fail.
Reported by Momchil Velikov <velco@fadata.bg>.
* sysdeps/generic/ifreq.h (__if_nextreq) [_HAVE_SA_LEN]: If sa_len
is > sizeof IFR->ifa_addr, advance past the whole longer length.
(__ifreq): Count up NIFS that way too.
Reported by Momchil Velikov <velco@fadata.bg>.
* sysdeps/mach/hurd/lchmod.c: Include <fcntl.h>.
* sysdeps/unix/sysv/linux/ifreq.h (__if_nextreq): New function.
* sysdeps/mach/hurd/ifreq.h (__if_nextreq): New function.
* sysdeps/gnu/ifaddrs.c (getifaddrs): Use __if_nextreq
for iterating through the list of interfaces.
* resolv/res_hconf.c (_res_hconf_reorder_addrs): Likewise.
* sysdeps/unix/grantpt.c (pts_name): Set errno when __ptsname_r fails.
Reported by Bruno Haible <bruno@clisp.org>.
This implementation supports only IPv4.
* inet/ifaddrs.h: New file.
* sysdeps/generic/ifaddrs.c: New file.
* sysdeps/gnu/ifaddrs.c: New file.
* inet/test-ifaddrs.c: New file.
* inet/Makefile (routines): Add ifaddrs.
(headers): Add ifaddrs.h here.
(tests): Add test-ifaddrs.
* inet/Versions (GLIBC_2.3): New set, add getifaddrs and freeifaddrs.
* resolv/res_hconf.c (_res_hconf_reorder_addrs): Use an explicit
socket call to get an AF_INET socket, instead of using __opensock.
The SIOCGIFNETMASK ioctl will work only with a PF_INET socket.
* sysdeps/generic/ifreq.h (__ifreq): Take third argument SOCKFD,
if not -1 use it instead of calling __opensock.
* sysdeps/unix/sysv/linux/ifreq.h (__ifreq): Likewise.
* sysdeps/mach/hurd/ifreq.h (__ifreq): Take new argument and ignore it.
* resolv/res_hconf.c (_res_hconf_reorder_addrs): Pass new argument.
* sysdeps/mach/hurd/ifreq.h: New file.
* sysdeps/generic/ifreq.h (__if_freereq): Take second argument NUM_IFS.
* sysdeps/unix/sysv/linux/ifreq.h (__if_freereq): Likewise.
* resolv/res_hconf.c (_res_hconf_reorder_addrs): Update caller.
