* Remove __need macros from signal.h.Zack Weinberg2017-05-209-465/+437
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * bits/sigevent-consts.h * bits/siginfo-consts.h * bits/types/__sigset_t.h * bits/types/sigevent_t.h * bits/types/siginfo_t.h * sysdeps/unix/sysv/linux/bits/sigevent-consts.h * sysdeps/unix/sysv/linux/bits/siginfo-consts.h * sysdeps/unix/sysv/linux/bits/types/__sigset_t.h * sysdeps/unix/sysv/linux/bits/types/sigevent_t.h * sysdeps/unix/sysv/linux/bits/types/siginfo_t.h: New system-dependent bits headers. * sysdeps/unix/sysv/linux/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/mips/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/x86/bits/siginfo-arch.h: New Linux-only system-dependent bits headers. * signal/bits/types/sig_atomic_t.h * signal/bits/types/sigset_t.h * signal/bits/types/sigval_t.h: New non-system-dependent bits headers. * sysdeps/generic/sigsetops.h * sysdeps/unix/sysv/linux/sigsetops.h: New internal headers. * include/bits/types/sig_atomic_t.h * include/bits/types/sigset_t.h * include/bits/types/sigval_t.h: New wrappers. * signal/sigsetops.h * bits/siginfo.h * bits/sigset.h * sysdeps/unix/sysv/linux/bits/siginfo.h * sysdeps/unix/sysv/linux/bits/sigset.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo.h * sysdeps/unix/sysv/linux/mips/bits/siginfo.h * sysdeps/unix/sysv/linux/s390/bits/siginfo.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo.h * sysdeps/unix/sysv/linux/tile/bits/siginfo.h * sysdeps/unix/sysv/linux/x86/bits/siginfo.h: Deleted. * signal/Makefile, sysdeps/unix/sysv/linux/Makefile: Update lists of installed headers. * posix/bits/types.h: Define __sig_atomic_t here. * signal/signal.h: Use the new bits headers; no need to handle __need_sig_atomic_t nor __need_sigset_t.

These vary in different ways between glibc configurations; in particular, the stack sizes vary much more than any of the other pieces. Furthermore, these pieces have different standard namespace rules for when they should be visible (not currently visible in conform/ results both because the relevant tests are XFAILed for sys/ucontext.h namespace issues, and because some of the expectations are incorrect in the same way as the headers, e.g. neither expectations nor headers reflect that current POSIX no longer has either the sigstack function or the sigstack structure). To reduce duplication of identical definitions, and facilitate namespace fixes without requiring the same feature test macro conditions to be repeated in many versions of the same header, this patch splits bits/sigstack.h up into four headers. It keeps the stack size macros, while new bits/types/struct_sigstack.h, bits/types/stack_t.h and bits/ss_flags.h are added for the other pieces. bits/types/struct_sigstack.h is the same everywhere, bits/types/stack_t.h has three variants different in the order of the structure elements (generic = MIPS Linux, and other Linux), and bits/ss_flags.h has generic and Linux variants. This patch includes the new headers everywhere that included <bits/sigstack.h>, so should cause no difference to what any public header defines. Subsequent namespace fixes would then remove or condition some of those includes. There should be no conflicts with Zack's changes to signal.h types, beyond the trivial conflict of both making additions to signal/Makefile's headers list; the two patches affect disjoint sets of types and other definitions.

* Add PF_SMC, AF_SMC from Linux 4.11 to bits/socket.h.Joseph Myers2017-05-011-1/+3
| | | | | | | | | | | This patch adds the PF_SMC / AF_SMC macros from Linux 4.11 to sysdeps/unix/sysv/linux/bits/socket.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/socket.h (PF_SMC): New macro. (PF_MAX): Set to 44. (AF_SMC): New macro.
* Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).Joseph Myers2017-04-251-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. [BZ #21426] * misc/bits/types/struct_iovec.h: New file. * misc/Makefile (headers): Add bits/types/struct_iovec.h. * include/bits/types/struct_iovec.h: New file. * bits/uio.h (struct iovec): Replace by inclusion of <bits/types/struct_iovec.h>. * sysdeps/unix/sysv/linux/bits/uio.h (struct iovec): Likewise. * socket/sys/socket.h: Include <bits/types/struct_iovec.h> instead of <sys/uio.h>. * nptl/tst-cancel4.c: Include <sys/uio.h> * posix/test-errno.c: Likewise. * support/resolv_test.c: Likewise. * conform/Makefile (test-xfail-POSIX2008/arpa/inet.h/conform): Remove.

* Fix bits/socket.h IOC* namespace issues (bug 21267).Joseph Myers2017-04-181-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/bits/socket.h includes asm/socket.h. That includes asm/sockios.h, which on MIPS includes asm/ioctl.h, resulting in namespace violations from IOC* macros. bits/socket.h already has code to handle asm/socket.h unconditionally defining macros that are only wanted for __USE_MISC. This patch extends it to handle the IOC* macros as well (always undefining them if not defined when bits/socket.h was included, as I don't think they are part of the intended API even for __USE_MISC). It's possible there should also be a kernel fix - it's not clear to me that IOC* belong in the uapi headers, and even if they do they might best be split out into another header to avoid getting defined by this particular path. But since glibc needs to deal with existing kernel headers, it also seems appropriate to extend the existing workaround to these macros. Tested (compilation only) with build-many-glibcs.py. [BZ #21267] * sysdeps/unix/sysv/linux/bits/socket.h (IOCSIZE_MASK): Undefine if defined by <asm/socket.h> and not previously defined. (IOCSIZE_SHIFT): Likewise. (IOC_IN): Likewise. (IOC_INOUT): Likewise. (IOC_OUT): Likewise.
* Add more IPV6_* macros to sysdeps/unix/sysv/linux/bits/in.h.Joseph Myers2017-03-131-0/+14
| | | | | | | | | | | | | | | | | | | | | Linux 4.10 adds IPV6_RECVFRAGSIZE to include/uapi/linux/in6.h, which shows that several such IPV6_* macros are missing from glibc's sysdeps/unix/sysv/linux/bits/in.h (while older ones are present). I don't know whether any of these might be deliberately omitted, but this patch adds what appear to be the missing more recent macros to glibc. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/in.h (IPV6_AUTOFLOWLABEL): New macro. (IPV6_ADDR_PREFERENCES): Likewise. (IPV6_MINHOPCOUNT): Likewise. (IPV6_ORIGDSTADDR): Likewise.

* Add IP_RECVFRAGSIZE from Linux 4.10.Joseph Myers2017-02-211-0/+1
| | | | | | | | | | Linux 4.10 adds a new IP_RECVFRAGSIZE macro to include/uapi/linux/in.h. This patch adds it to glibc's sysdeps/unix/sysv/linux/bits/in.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/in.h (IP_RECVFRAGSIZE): New macro.

| | | | | | | | | | | | | | | This patch makes bits/fcntl-linux.h include <linux/falloc.h> to define the FALLOC_* flags under __USE_GNU (linux/falloc.h defines only those bits, nothing else). Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/bits/fcntl-linux.h [__USE_GNU]: Include <linux/falloc.h>. (FALLOC_FL_KEEP_SIZE): Remove. (FALLOC_FL_PUNCH_HOLE): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h.

* Installed-header hygiene (BZ#20366): time.h types.Zack Weinberg2016-09-233-45/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many headers are expected to expose a subset of the type definitions in time.h. time.h has a whole bunch of messy logic for conditionally defining some its types and structs, but, as best I can tell, this has never worked 100%. In particular, __need_timespec is ineffective if _TIME_H has already been defined, which means that if you compile #include <time.h> #include <sched.h> with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get In file included from test.c:2:0: /usr/include/sched.h:74:57: warning: "struct timespec" declared inside parameter list will not be visible outside of this definition or declaration extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW; ^~~~~~~~ And if you want to _use_ sched_rr_get_interval in a TU compiled that way, you're hosed.

The meat of this change was mechanically generated by the following shell command: perl -pi~ -e ' s/\b(__)?u_char\b/unsigned char/g; s/\b(__)?u_?short\b/unsigned short/g; s/\b(__)?u_?int\b/unsigned int/g; s/\b(__)?u_?long\b/unsigned long/g; s/\b(__)?u_int8_t\b/uint8_t/g; s/\b(__)?u_int16_t\b/uint16_t/g; s/\b(__)?u_int32_t\b/uint32_t/g; s/\b(__)?u_int64_t\b/uint64_t/g; s/\b(__)?u_quad_t\b/uint64_t/g; s/\b(__)?quad_t\b/uint64_t/g; ' $(grep -lE -e '\<((__)?(quad_t|u(short|int|long|_(char|short|int([0-9]+_t)?|long|quad_t))))\>' \ $(grep -LE '\<(_(SYS|BITS)_TYPES_H|rpc/(rpc|rpc_msg|types|xdr)\.h)\>' \ $(find . \( -false $(sed 's/^/-o -name /' all-installed-headers) \ \) -printf '%P\n' | sort -u))) where 'all-installed-headers' was a list of the basenames of all installed header files, manually extracted from the Makefiles. Non-installed wrapper headers in include/ are also adjusted, for consistency. I then manually fixed up indentation and line-wrapping. sys/types.h and bits/types.h are excluded because they must continue to define the u_* types (under __USE_MISC) for compatibility with applications. They do not use these types themselves. All headers that (transitively) include rpc/types.h are also excluded, for three reasons. First, the u_* types are defined by rpc/types.h, unconditionally (not just under __USE_MISC) so they are logically part of the SunRPC API. Second, many of those headers appear to be machine-generated. Third, it's my understanding that we are getting rid of as much of SunRPC as possible in the near future. (The one file under sunrpc/ that's touched, sunrpc/rpc/rpc_des.h, does *not* include rpc/types.h. This may itself be a bug.) After changing from u_intNN_t to uintNN_t, a number of headers now need to include stdint.h to pick up those types. It might be more hygenic, namespace-wise, to use __uintNN_t instead, but none of these headers are bound by ISO or POSIX to do so, and it's unlikely that anyone using them will be bothered. (The two files that were using __-prefixed versions of the u_types, sysdeps/mach/hurd/net/route.h and sysdeps/unix/sysv/linux/net/route.h, both already also contained uses of the unprefixed versions.) Some of these files directly included features.h and/or sys/cdefs.h, which I removed, as the style generally seems to be to let sys/types.h do that for us. (This does not change the set of definitions exposed by any header; sys/types.h unconditionally includes both features.h and sys/cdefs.h.)

* Installed-header hygiene (BZ#20366): Simple self-contained fixes.Zack Weinberg2016-09-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some headers did not include all of their prerequisite headers. * rpcsvc/nislib.h: Include rpcsvc/nis.h. * sysdeps/unix/sysv/linux/netrose/rose.h: Include sys/socket.h and netax25/ax25.h. <endian.h> only defines BYTE_ORDER, BIG_ENDIAN, LITTLE_ENDIAN, etc. under __USE_MISC; glibc's headers should use __BYTE_ORDER, __BIG_ENDIAN, __LITTLE_ENDIAN, etc. instead. * inet/netinet/icmp6.h, inet/netinet/ip6.h * resolv/arpa/nameser_compat.h: Use __BYTE_ORDER etc. instead of BYTE_ORDER etc. sys/types.h only conditionally defines caddr_t and clockid_t. * sysdeps/unix/sysv/linux/sys/quota.h: Use __caddr_t instead of caddr_t. * sysdeps/unix/sysv/linux/sys/timerfd.h: Use __clockid_t instead of clockid_t. Remove a #warning that was the sole actual problem with using sys/ipc.h without _GNU_SOURCE/_XOPEN_SOURCE. * sysvipc/sys/ipc.h: Remove unnecessary #warning. _LIBC, __USE_XOPEN2K8, and __STDC_VERSION__ are not always defined. It seems to me that _LIBC should not appear in installed headers, but avoiding that for argp specifically would require more surgery than feels appropriate for this patch set. It's possible that "#ifdef _LIBC" would be sufficient, but I wanted to be conservative. All three versions of bits/socket.h want to know whether __flexarr will produce a real flexible array member -- specifically, one that doesn't alter sizeof(the structure containing it). They were testing for this with a complicated #if condition that did not agree with sys/cdefs.h and that tripped -Wundef warnings under -std=c90. I added a new macro to sys/cdefs.h, __glibc_c99_flexarr_available, which reveals exactly what these headers want to know. I also took the opportunity to flatten the rather messy conditional nest defining __flexarr. * argp/argp.h: Check whether _LIBC is defined before expanding it. * posix/glob.h: Check whether __USE_XOPEN2K8 is defined instead of expanding it. * misc/sys/cdefs.h: Tidy up conditional nest defining __flexarr. Define __glibc_c99_flexarr_available to 1 when the compiler supports C99-compatible flexible array members, 0 otherwise. * sysdeps/unix/sysv/linux/bits/socket.h * sysdeps/mach/hurd/bits/socket.h * bits/socket.h: Use __glibc_c99_flexarr_available in definitions of struct cmsghdr and CMSG_DATA.

And kernel current also add some limits to the values on the internal msghdr and cmsghdr fields: - msghdr::msg_iovlen larger than UIO_MAXIOV (1024) returns EMSGSIZE. - msghdr::msg_controllen larger than INT_MAX returns ENOBUFS. * There is a small performance hit for recvmsg/sendmsg/recmmsg which is neglectable, but it is a big hit for sendmmsg since now instead of calling the syscall for the packed structure, GLIBC is calling multiple sendmsg. This defeat the very existence of the syscall. * It currently breaks libsanitizer build on GCC [1] (I fixed on compiler-rt). However the fix is incomplete because it does add any runtime check since libsanitizer currently does not have any facility to intercept symbols with multiple version [2]. This, along with incorret dlsym/dlvsym return for versioned symbol due another bug [3], makes hard to interpose versioned symbols. Also, current approach of fixing GCC PR#71445 leads to half-baked solutions without versioned symbol interposing. This patch basically reverts commits 2f0dc39029ae08, 222c2d7f4357d66, af7f7c7ec8dea1. I decided to not revert abf29edd4a3918 (Adjust kernel-features.h defaults for recvmsg and sendmsg) mainly because it does not really address the POSIX compliance original issue and also adds some cleanups.

* Bug 20214: Fix linux/in6.h and netinet/in.h sync.Carlos O'Donell2016-06-071-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | In: https://sourceware.org/glibc/wiki/Synchronizing_Headers we explain how we synchronize our headers with Linux kernel headers. In order to synchronize with the Linux linux/in6.h and linux/ipv6.h headers we checked for their guard macros and then defined __USE_KERNEL_IPV6_DEFS and conditionalized code on this macro. In upstream kernel 56c176c9 the _UAPI prefix was stripped and this broke our synchronized headers again. We now need to check for _LINUX_IN6_H and _IPV6_H, and keep checking the old versions of the header guard checks for maximum backwards compatibility with older Linux headers (the history is actually a bit muddled here and it appears upstream linus kernel broke this 10 months *before* our fix was ever applied to glibc, but without glibc testing we didn't notice and distro kernels have their own testing to fix this). This patch fixes synchronization with linux/in6.h and with netinet/in.h.
* Fix macro API for __USE_KERNEL_IPV6_DEFS.Carlos O'Donell2016-06-021-1/+3
| | | | | | | | | | | | | | | | The use of __USE_KERNEL_IPV6_DEFS with ifndef is bad practice per: https://sourceware.org/glibc/wiki/Wundef. This change moves it to use 'if' and always define the macro. Please note that this is not the only problem with this code. I have a series of fixes after this one to resolve breakage with this code and add regression tests for it via compile-only source testing (to be discussed in another thread). Unfortunately __USE_KERNEL_XATTR_DEFS is set by the kernel and not glibc, and uses 'define', so we can't fix that yet.

* Make padding in struct sockaddr_storage explicit [BZ #20111]Florian Weimer2016-05-231-4/+4
| | | | | | | | | | This avoids aliasing issues with GCC 6 in -fno-strict-aliasing mode. (With implicit padding, not all data is copied.) This change makes it explicit that struct sockaddr_storage is only 126 bytes large on m68k (unlike elsewhere, where we end up with the requested 128 bytes). The new test case makes sure that this does not happen on other architectures.
* Update sysdeps/unix/sysv/linux/bits/socket.h for Linux 4.6.Joseph Myers2016-05-231-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/bits/socket.h for new constants added in Linux 4.6. AF_KCM / PF_KCM are added. SOL_KCM is new, and I added a lot of SOL_* values postdating the last one present in the header, since I saw no apparent reason for the set in glibc to stop at SOL_IRDA. MSG_BATCH is added; Linux also has MSG_SENDPAGE_NOTLAST which is not in glibc, but given the comment starts "sendpage() internal" I presume it's correct for it not to be in glibc. (Note that this is a case where the Linux kernel header with userspace relevant values is *not* a uapi header but include/linux/socket.h - I don't know why, but at least this header, as well as uapi headers, needs reviewing for glibc-relevant changes each release.) Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * sysdeps/unix/sysv/linux/bits/socket.h (PF_KCM): New macro. (PF_MAX): Update value.

This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-124-6/+6

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.)
