As with sys/socket.h and struct sockaddr, most of the files including
netinet/in.h just want struct sockaddr_in or a related type, so
introduce bits/types headers for these. POSIX specifically allows
arpa/inet.h to include netinet/in.h and I think it makes sense to
preserve that. The definition of struct sockaddr_in had a dependence
on the definition of struct sockaddr; to avoid that, bits/sockaddr.h
grows a new macro, __SOCKADDR_DATA_SIZE, which is the declared size of
struct sockaddr.sa_data.
On Linux, some kernel headers (notably linux/in.h and linux/in6.h)
attempt to cooperate with a C library’s headers in defining types such
as struct sockaddr_in. There is a set of macros whose names begin
with __UAPI_DEF_ that indicate that a type has already been defined.
This mechanism doesn’t actually work with the kernel headers as they
are in 5.0, as far as I can tell, but it could be made to work with
straightforward changes, so it makes sense for us to support it to the
extent we can. To do this sensibly I need to introduce a new bits
header called bits/uapi-compat.h, with a trivial definition for
non-Linux. This replaces the existing __USE_KERNEL_IPV6_DEFS macro.
* bits/sockaddr.h (__SOCKADDR_DATA_SIZE): New macro.
* sysdeps/unix/bsd/bits/sockaddr.h: Likewise.
* sysdeps/unix/sysv/linux/m68k/bits/sockaddr.h: Likewise.

(__USE_KERNEL_IPV6_DEFS): Don’t define.
* sysdeps/unix/sysv/linux/bits/in.h: Similarly.

New single-type headers, factored out of inet/netinet/in.h.
Add __UAPI_DEF_* conditionals where appropriate, and verify that
all conditionalized definitions agree with the relevant
OS-supplied header. Use __SOCKADDR_DATA_SIZE to set size of sin_zero.
* inet/Makefile: Install the new single-type headers.
* inet/netinet/in.h: Include bits/uapi-compat.h.
Define in_addr_t, in_port_t, struct in_addr, struct in6_addr,
struct sockaddr_in, and struct sockaddr_in6 by including the
above single-type headers, not directly. Replace all
__USE_KERNEL_IPV6_DEFS conditionals with appropriate __UAPI_DEF_*
conditionals. Add appropriate __UAPI_DEF_* conditionals around
the definitions of the IPPROTO_* constants, the IN_CLASS
macros, and struct ip_mreq. Import IN_LOOPBACK macro from
Linux 5.0 linux/in.h and verify all other conditionalized
definitions agree with the relevant linux/ header.
Define IPPORT_RESERVED only if not already defined, and make it a
macro so we can tell.

No standard public header is required to include sys/socket.h,
although some are allowed to. Several public headers need the
definitions of socklen_t, struct sockaddr, and/or struct
sockaddr_storage, but nothing else from sys/socket.h. We already have
a single-type header for socklen_t, so this patch adds single-type
headers for struct sockaddr and struct sockaddr_storage.
The definition of struct sockaddr_storage is subtly different on Linux
than on the Hurd; in order to not need two copies of
bits/types/struct_sockaddr_storage.h, bits/sockaddr.h is now
responsible for defining __ss_aligntype if ‘unsigned long int’ is not
the correct definition.
I also added a single-type header for struct linger, even though only
sys/socket.h is expected to define that, just because all three copies
of bits/socket.h were defining it exactly the same way. There would
also be a case for defining it directly in sys/socket.h but this
seemed tidier.
I did *not* create single-type headers for struct msghdr and struct
cmsghdr, because those and their helper macros are not consistent
among the three copies of bits/socket.h, and, again, only sys/socket.h
is expected to define them.
The large number of .c files that add an `#include <sys/socket.h>`
might make this look like it’s not worth doing. However, after this
change, only half of the files in the glibc source tree that include
netinet/in.h also need to include sys/socket.h, and only a third of
the files that include netdb.h need to include sys/socket.h. Before,
all of the files in both groups were getting sys/socket.h. That seems
like enough justification to me.
While I was at it I noticed that sys/socketvar.h is yet another
backward compatibility header that does nothing but include some other
header (sys/socket.h, in this case) and also doesn’t need to be
system-dependent.
* socket/bits/types/struct_linger.h
* socket/bits/types/struct_sockaddr.h
* socket/bits/types/struct_sockaddr_storage.h:
New single-type headers, factored out of the various bits/socket.h
headers.
* include/bits/types/struct_linger.h
* include/bits/types/struct_sockaddr.h
* include/bits/types/struct_sockaddr_storage.h:
New wrappers.
* socket/Makefile (headers): Add bits/types/struct_linger.h,
bits/types/struct_sockaddr.h, and bits/types/struct_sockaddr_storage.h.
Alphabetize the list.
* bits/socket.h, sysdeps/mach/hurd/bits/socket.h
* sysdeps/unix/sysv/linux/bits/socket.h:
Don’t define struct sockaddr, struct sockaddr_storage,
__ss_aligntype, or struct linger here. Minimize inclusions.

* socket/sys/socket.h: Include bits/types/struct_linger.h,

Many public headers include sys/types.h and/or stdint.h when they only
need and/or are supposed to define a small number of types from that
header. This patch changes as many of them as practical to include
only the single-type headers for the types they are actually specified
to define, and use the impl-namespace aliases for any types they need
but are not specified to define. In most cases, where a header has
historically used uintN_t types, I changed it to use __uintN_t types;
in a few cases I chose to have it continue to define the complete set
of those types (using <bits/stdint-uintn.h>).
After this patch, the public headers that still include sys/types.h are:
stdlib.h and sys/param.h, where removal would risk breaking far too much;
the inclusion of sys/types.h; regex.h, which is taken verbatim from
gnulib and can't include features.h directly (I'm open to better ideas);
sys/bitypes.h, which is an alternative name for sys/types.h; and
the networking headers, which will be dealt with separately. The headers
that still include stdint.h are: inttypes.h, as required by ISO C;
elf.h and thread_db.h, see discussion of debugger interface headers below;
and, again, the networking headers will be dealt with separately.
While I was at it, I moved headers out of sysdeps where possible: If
we have only a sysdeps/generic/something.h or sysdeps/gnu/something.h,
no other sysdeps variants, it is not really system-dependent and can
be moved to the directory that installs it. If we have both
sysdeps/generic/ and gnu/something.h, the generic version is never
used (since we support only GNUish systems these days) and can be
deleted, and the gnu-version can be moved to the directory that
installs it. If the only copy of a bits header is in the
top-level bits directory, it is not system-dependent.
For utmp.h and utmpx.h, I think we might be able to fold their
respective bits headers into the primary headers and make them not
system-dependent at all. The remaining variation is between
s390*-*-linux* and everything else, and it appears to me that the s390
versions of the bits headers are actually the headers that everyone
should be using. The only difference is that the s390 headers
unconditionally use 64-bit quantities for lastlog.ll_time,
utmp{,x}.ut_tv, and utmp{,x}.ut_session, whereas the generic headers
use either 64- or 32-bit quantities depending on
__WORDSIZE_TIME64_COMPAT32. I could be wrong, but I don’t think it
makes sense for programs with 64-bit and 32-bit time_t to have
different ideas of the layout of a structures that are copied directly
to and from a shared file on disk. But fixing that doesn’t belong in
this patch series.
The conform tests expect utmpx.h to define time_t and suseconds_t.
These are the public names for the types of the fields of struct
timeval, and utmpx.h is required to define struct timeval, so this is
a reasonable expectation even though POSIX doesn't _explicitly_ say
it's also required to define time_t and suseconds_t. utmp.h is not a
standard header but it makes sense for it to be as consistent with
utmpx.h as possible, especially in our implementation where
/var/log/utmp and /var/log/utmpx have the same format.
I thought I was going to need to change all of the arch-specific
bits/epoll.h headers as well as sys/epoll.h, but it turned out not to
be necessary. I still took the opportunity to give them all multiple
inclusion guards.
I suspect we do not need as many copies of bits/fcntl.h and bits/sem.h
as we have, but that’s complicated enough that it deserves its own patchset.
The debugger interface headers are a mess and I only have so much
patience for them. This does the bare minimum required for
thread_db.h, sys/procfs.h, and sys/user.h, which are at least
nominally cross-platform interfaces, to avoid including sys/types.h,
sys/time.h, and/or signal.h. Exposure of sys/ucontext.h is reduced
but not eliminated. Cross-architecture consistency should be improved.
It would be desirable to stop including stdint.h from elf.h and
thread_db.h as well, but that would involve touching dozens more
bits headers and I ran out of patience.
Git does not understand “remove file X and then rename file Y over the
top of it” very well, so the diff looks bigger than it should.
This is another partial fix for Hurd-specific bug 23088. The headers

sys/un.h needs strlen in order to define SUN_LEN, but does not need
any of the other things declared by string.h; the path of least
resistance is to prototype strlen locally.
Also, the construct being used to get the size of everything up to the
sun_path member contains a formal dereference of a null pointer and
therefore has undefined behavior. Replace with __SOCKADDR_COMMON_SIZE.
Some old RPC code was relying on sys/un.h to provide all of string.h.

This is supposedly present for BSD compatibility, but the current
generation of BSDs is not consistent about it: FreeBSD does, OpenBSD
doesn’t, NetBSD exposes only fd_set and the FD_* macros. Programs
that need to wait for any of multiple I/O events have several
alternatives to select nowadays, so I think it makes sense to expose
select only to programs that specifically want it.
Only a few places within our own code are affected. A few test
programs need to include sys/select.h explicitly, as does rpc/svc.h.
sysdeps/nptl/thread_db.h needs to declare sigset_t, and
sysdeps/unix/sysv/linux/pselect.c was including sys/poll.h instead of
sys/select.h, which is probably a copy-and-paste error. sys/socket.h
needs to forward-declare struct timespec under __USE_GNU, because
recvmmsg has a struct timespec * argument; I’m open to the possibility
of having it fully declare struct timespec.
I considered taking sys/select.h out of sys/time.h as well, but POSIX
not only explicitly allows this inclusion, it requires sys/time.h to
declare almost everything that sys/select.h declares. It doesn’t seem
worth creating another bits header just to prevent sys/time.h from
declaring pselect, sigset_t, and struct timespec.
Not including sys/select.h from sys/types.h means that sys/types.h
also no longer defines anything from sys/time.h, and a couple of files
were relying on that. (pthread_join_common.c should be using
clock_gettime instead of gettimeofday, but that's out of scope for
this patch series.)

We rely on the compiler's stddef.h and stdarg.h to define size_t,
ptrdiff_t, wchar_t, NULL, and __gnuc_va_list, and to implement a
convention that allows us to request the definition of a specific one:
for instance
#define __need_size_t
#include <stddef.h>
is expected to define size_t but not any of the other things stddef.h
defines.
This patch hides that convention behind a set of bits/types/ headers,
which allows check-obsolete-constructs.py to verify that none of our
headers include these headers unconditionally. (Both of them define
at least one item in the user namespace that no other header is
supposed to expose.) It will also facilitate coping with compilers
that don’t implement the __need convention. (That scenario is not
hypothetical, see the next patch.)
Only public headers use the new bits headers. Non-public headers and
.c files in our codebase, that were formerly defining __need macros,
now just include stddef.h and/or stdarg.h without any __need macros.
A few files didn’t need to be including stddef.h / stdarg.h at all.
Uses of NULL in public headers that aren’t expected to define NULL
are changed to a bare 0. bits/NULL.h is only used by headers that
are expected to define NULL.
malloc.h and printf.h were, in fact, including stddef.h and/or
stdarg.h unconditionally; they no longer do that. This broke a few of
our test cases, which are fixed by adding appropriate inclusions to
the relevant .c files.

The convention throughout glibc is that every public header includes
features.h directly, as its first action, and relies on features.h to
include sys/cdefs.h. In a few places, though, it’s been done the
other way around, usually in headers that were copied from a BSD
source (where the convention is exactly the opposite). This patch
makes all installed headers match the glibc convention.
This patch also corrects a bug in glob.h: it may declare size_t
without notifying stddef.h that it has done this, so e.g.
#define _XOPEN_SOURCE 700
#include <glob.h>
#include <stddef.h>
int dummy;
declares size_t twice, which is invalid prior to C2011. I wasn’t able
to persuade gcc 8 to issue an error, even with -std=c89 -Wsystem-headers,
but clang is not so lenient.
* posix/glob.h: Include features.h, not sys/cdefs.h.
When __USE_XOPEN || USE_XOPEN2K8, include stddef.h for size_t;
otherwise, issue an immediate #error if __SIZE_TYPE__ is not
available. Use __gsize_t, not __size_t, as an impl-namespace
alternative name for size_t.

sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *. void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.
Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net). I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.

The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h. The others
get bits/types/ headers.
Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion. Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API). Relatedly, the public signal.h no longer
declares any of those functions. The obsolete sigmask() macro no
longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.
New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary. Ports to other operating systems
are strongly encouraged to generalize this scheme further.

sys/socket.h includes sys/uio.h to get the definition of the iovec
structure.
POSIX allows sys/socket.h to make all sys/uio.h symbols visible.
However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this
results in conformtest failures (for sys/socket.h and other headers
that include it):
Namespace violation: "UIO_MAXIOV"
Namespace violation: "readv"
Namespace violation: "writev"
Now, there is some ambiguity in POSIX about what namespace
reservations apply in this case - see
http://austingroupbugs.net/view.php?id=1127 - but glibc convention
would still avoid declaring readv and writev, for example, for feature
test macros that don't include them (if only headers from the relevant
standard are included), even if such declarations are permitted, so
there is a bug here according to glibc conventions.
This patch moves the struct iovec definition to a new
bits/types/struct_iovec.h header and includes that from sys/socket.h
instead of including the whole of sys/uio.h. This fixes the namespace
issue; however, three files in glibc that were relying on the implicit
inclusion needed to be updated to include sys/uio.h explicitly. So
there is a question of whether sys/socket.h should continue to include
sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or
__USE_XOPEN || __USE_MISC, for greater compatibility with code that
(wrongly) expects this optional inclusion to be present there. (I
think the three affected files in glibc should still have explicit
sys/uio.h inclusions added in any case, however.)
Tested for x86_64.

Simplify the Linux accept4 implementation based on the assumption
that it is available in some way. __ASSUME_ACCEPT4_SOCKETCALL was
previously unused, so remove it.
For ia64, the accept4 system call (and socket call) were backported
in kernel version 3.2.18. Reflect this in the installation
instructions.

glibc before this commit) contain an implementation of pipe2.

Several network-related structures are defined conditionally under
__USE_MISC, but unconditionally used by other headers. The path of
least resistance is usually to condition the uses on __USE_MISC as
well.
* sysdeps/mach/hurd/net/if_ppp.h
* sysdeps/unix/sysv/linux/net/if_ppp.h:
Only define struct ifpppstatsreq and struct ifpppcstatsreq
if __USE_MISC is defined, to ensure struct ifreq is declared.
* inet/netinet/ether.h: Condition all function prototypes
on __USE_MISC, to ensure struct ether_addr is declared.
sys/socket.h defines struct osockaddr only under __USE_MISC, whereas
protocols/talkd.h requires it unconditionally. Here it doesn't make
sense to condition the entire body of protocols/talkd.h on __USE_MISC.
Rather than complicate sys/socket.h with a __need macro or duplicate
the definition, I am introducing a new concept: tiny headers named
bits/types/TYPE.h that define TYPE and nothing else. This can, I hope,
ultimately replace *all* the __need macros. The guard macro for such
headers will be __TYPE_defined, just in case application or third-party
library code is looking at them.
* socket/bits/types/struct_osockaddr.h: New header.
* include/bits/types/struct_osockaddr.h: New wrapper.
* socket/Makefile: Install the new header.

This fixes (harmless) data races when accessing the various
__have_sock_cloexec variables.

This automatically-generated patch converts 703 function definitions
in glibc from old-style K&R to prototype-style.
This conversion is deliberately simplistic, excluding any tricky cases
as even a patch covering only simple cases is still very large.
Currently excluded are: sysdeps files (to improve test coverage for
the initial patch); files containing assertions (to avoid line number
changes so that generated libraries can be compared); any cases where
the generated function declaration would involve lines over 79
characters and so need to be wrapped; any cases with array parameters
or other cases where parameter declarators don't end with the
parameter name; any other cases that my script didn't parse.
I didn't try to make the ChangeLog generation indicate when function
definitions are conditional; it just lists the functions changed
without regard to that.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/libc-lock.h to plain libc-lock.h and
bits/libc-lockP.h to plain libc-lockP.h to follow that convention.
Note that I don't know where libc-lockP.h comes from for Hurd (the
Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in
the glibc source tree is for NPTL) - some unmerged patch? - but I
updated the #include in the Hurd libc-lock.h anyway.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

mq_notify (in the 1996 edition of POSIX) brings in references to recv
and socket (not in POSIX until the 2001 edition). This patch fixes
this by using __recv and __socket, exporting them from libc at version
GLIBC_PRIVATE.
Tested for x86_64 and x86 (testsuite and comparison of installed
stripped shared libraries; PLT / dynamic symbol table changes render
the comparison not particularly useful for libc).

In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information. No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.
This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules). Includes are added if needed, or moved up if already
present. Subdirectory "all:" targets are removed, since Makeconfig
provides one.
There is potential for further cleanups I haven't done. Rules and
Makerules have code such as
ifneq "$(findstring env,$(origin headers))" ""
headers :=
endif
to override to empty any value of various variables that came from the
environment. I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable. (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.) Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves. The special code to override values coming
from the environment would then be obsolete and could be removed.
Tested x86_64, including that installed binaries are identical before
and after the patch.

This patch cleans up following the obsoletion of _BSD_SOURCE and
_SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC.
The only non-mechanical part of this patch is the changes to
features.h; everything else is simple substitution of __USE_MISC for
the old macros. Thus, this patch leaves obviously redundant
conditionals such as "defined __USE_MISC || defined __USE_MISC", and
does not update #endif comments where they referred to BSD or SVID in
words instead of the literal macro name. This is intended to
facilitate patch review by separating the less mechanical changes from
these purely mechanical changes into a separate patch. (I do intend
to integrate all the changes from
<https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I
believe includes all the trailing comment updates, in subsequent
patches.)

We can't assume sock_cloexec and pipe2 are bound together as the former
defines are found in glibc only while the latter are a combo of kernel
headers and glibc. So if we do a runtime detection of SOCK_CLOEXEC, but
pipe2() is a stub inside of glibc, we hit a problem. For example:
main()
{
getgrnam("portage");
if (!popen("ls", "r"))
perror("popen()");
}
getgrnam() will detect that the kernel supports SOCK_CLOEXEC and then set
both __have_sock_cloexec and __have_pipe2 to true. But if glibc was built
against older kernel headers where __NR_pipe2 does not exist, glibc will
have a ENOSYS stub for it. So popen() will always fail as glibc assumes
pipe2() works.
While this isn't too much of an issue for some arches as they added the
functionality to the kernel at the same time, not all arches are that
lucky.
Since the code already has dedicated names for each feature, delete the
defines wiring these three features together and make each one a proper
dedicated knob.
We've been carrying this in Gentoo since glibc-2.9.
