Dmitry V. Levin	e0043e17df	Fix linux personality syscall wrapper ... The personality system call, starting with linux kernel commit v2.6.29-6609-g11d06b2a1e5658f448a308aa3beb97bacd64a940, always successfully changes the personality if requested. The syscall wrapper, however, still can return an error in the following cases: - the value returned by the system call looks like an error due to architecture limitations of 32-bit kernels; - a personality greater than 0xffffffff is passed to the system call, and the 64-bit kernel does not have commit v2.6.35-rc1-372-g485d527686850d68a0e9006dd9904f19f122485e that would truncate this value to unsigned int; - on sparc64, the value returned by the system call looks like an error due to sparc64 kernel sign extension bug. The solution is three-fold: - move generic syscalls.list personality entry to generic 64-bit syscalls.list file; - for each 32-bit architecture that use negated errno semantics, add a NOERRNO personality entry to their syscalls.list file; - for sparc64 and 32-bit architectures that use dedicated registers to flag syscall errors, add a wrapper around personality syscall; if the system call return value is flagged as an error, this wrapper returns the negated "would be errno" value, otherwise it returns the system call return value; on sparc64, it also truncates the personality argument to unsigned int before passing it to the kernel.

Joseph Myers	e5a5315e2d	Use direct socket syscalls for new kernels on i386, m68k, microblaze, sh. ... Now that we have __ASSUME_* macros for direct socket syscalls to use them instead of socketcall when they can be assumed to be available on socketcall architectures, this patch defines those macros when appropriate for i386, m68k, microblaze and sh (for 4.3, 4.3, all supported kernels and 2.6.37, respectively; the only use of socketcall support on microblaze is it allows accept4 and sendmmsg to be supported on a wider range of kernel versions). David, it seems that 32-bit SPARC is the only architecture supported by glibc that still lacks these direct syscalls. It would be good to get them added to the SPARC kernel so we can eventually eliminate socketcall support in glibc (and thereby just use entries in sysdeps/unix/syscalls.list for most of these functions) when we can assume new-enough kernels. Tested for i386 (testsuite, and that installed shared libraries are unchanged by this patch - not using a new enough kernel, so this doesn't actually test much, but the i386 and m68k code is essentially the same as that already in use for s390). * sysdeps/unix/sysv/linux/i386/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x040300] (__ASSUME_SOCKET_SYSCALL): New macro.

Joseph Myers	d709042a6e	Fix lgamma setting signgam for ISO C (bug 15421). ... The lgamma (and likewise lgammaf, lgammal) function wrongly sets the signgam variable even when building for strict ISO C conformance (-std=c99 / -std=c11), although the user may define such a variable and it's only in the implementation namespace for POSIX with XSI extensions enabled. Following discussions starting at <https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems that the safest approach for fixing this particular issue is for signgam to become a weak alias for a newly exported symbol __signgam, with the library functions only setting __signgam, at which point static linker magic will preserve the alias for newly linked binaries that refer to the library's signgam rather than defining their own, while breaking the alias for programs that define their own signgam, with new symbol versions for lgamma functions and with compat symbols for existing binaries that set both signgam and __signgam. This patch implements that approach for the fix. signgam is made into a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal get new symbol versions at version GLIBC_2.23, with the existing versions of lgamma, lgammaf and lgammal becoming compat symbols. When the compat versions are built, gamma, gammaf and gammal are aliases for the compat versions (i.e. always set signgam); this is OK as they are not ISO C functions, and avoids adding new symbol versions for them unnecessarily. When the compat versions are not built (i.e. for static linking and for future glibc ports), gamma, gammaf and gammal are aliases for the new versions that set __signgam. The ldbl-opt versions are updated accordingly. The lgamma wrappers are adjusted so that the same source files, included from different files with different definitions of USE_AS_COMPAT, can build either the new versions or the compat versions. Similar changes are made to the ia64 versions (untested). Tests are added that the lgamma functions do not interfere with a user variable called signgam for ISO C, with various choices for the size of that variable, whether it is initialized, and for static and dynamic linking. The conformtest whitelist entry is removed as well. Tested for x86_64, x86, mips64 and powerpc, including looking at objdump --dynamic-syms output to make sure the expected sets of symbols were aliases. Also spot-tested that a binary built with old glibc works properly (i.e. gets signgam set) when run with new glibc.

H.J. Lu	fb1cf10811	Add INLINE_SYSCALL_ERROR_RETURN_VALUE ... For ia32 PIC, the first thing of many syscalls does is to call __x86.get_pc_thunk.reg to load PC into reg in case there is an error, which is required for setting errno. In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg.

Joseph Myers	de071d199a	Move bits/atomic.h to atomic-machine.h (bug 14912). ... 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.

Adhemerval Zanella	fdb7d390dd	libio: fmemopen rewrite to POSIX compliance ... This patch added a new fmemopen version, for glibc 2.22, that aims to be POSIX complaint. It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'. This is default mode and 'b' opening mode does not change internal behavior (bz#6544). * fix apending opening mode to use as start position either first null byte of len specified in function call (bz#13152 and #13151). * remove binary option 'b' and internal different handling (bz#12836) * fix seek/SEE_END with negative values (bz#14292). A compatibility symbol is provided to with old behavior for older symbols version (2.2.5). * include/stdio.h (fmemopen): Remove hidden prototype. (__fmemopen): Add new hidden prototype. * libio/Makefile: Add oldfmemopen object. * libio/Versions [GLIBC_2.22]: Add new fmemopen symbol. * libio/fmemopen.c (__fmemopen): Function rewrite to be POSIX compliance. * libio/oldfmemopen.c: New file: old fmemopen implementation for symbol compatibility. * stdio-common/Makefile [tests]: Add new tst-fmemopen3. * stdio-common/psiginfo.c [psiginfo]: Call __fmemopen instead of fmemopen. * stdio-common/tst-fmemopen3.c: New file: more fmemopen tests, focus on append and read mode. * sysdeps/unix/sysv/linux/aarch64/libc.abilist [GLIBC_2.22]: Add fmemopen. * sysdeps/unix/sysv/linux/alpha/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist [GLIBC_2.22]: Likewise.	2015-07-08 12:07:21 -03:00
Adhemerval Zanella	60dce8b904	Remove socket.S implementation ... This patch removes the socket.S implementation for all ports and replace it by a C implementation using socketcall. For ports that implement the syscall directly, there is no change. The patch idea is to simplify the socket function implementation that uses the socketcall to be based on C implemetation instead of a pseudo assembly implementation with arch specific parts. The patch then remove the assembly implementatation for the ports which uses socketcall (i386, microblaze, mips, powerpc, sparc, m68k, s390 and sh). I have cross-build GLIBC for afore-mentioned ports and tested on both i386 and ppc32 without regressions.	2015-05-22 17:38:06 -03:00

This includes running ld.so through check-localplt, check-textrel, and check-execstack.

This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version.

Joseph Myers	f7b425175c	Support and use mixed compat/non-compat aliases in syscalls.list. ... This patch enables syscalls.list entries to specify both compat and non-compat symbol versions for the same syscall definition, making use of this for setrlimit / chown / lchown where the inability to specify such aliases showed up in the course of work on bug 14138. The change to make-syscalls.sh is minimal: adding a SHARED conditional on the compat_symbol calls. It remains the case that if a compat symbol version is specified, the syscall is only built for the shared library at all if an explicit symbol version is given for a non-compat symbol (so it's necessary to specify "lchown@@GLIBC_2.0 chown@GLIBC_2.0" rather than just "lchown chown@GLIBC_2.0"). It also remains the case, as already commented in make-syscalls.sh, that no SHLIB_COMPAT conditionals are generated, so there would be problems if the same syscalls.list file, with compat symbols, were used for both configurations that should have those symbols and configurations for which they should be conditioned out with SHLIB_COMPAT.

Joseph Myers	abb280f799	Move some chown / lchown / fchown definitions to syscalls.list (bug 14138). ... Continuing the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch moves various definitions of chown, lchown and fchown. In most cases the need for special syscalls.list entries (rather than existing generic ones) is because these architectures use chown32, lchown32 and fchown32 as syscall names. Some architectures also have symbol versioning compatibility for older versions of chown having been equivalent to lchown. In the case of powerpc, chown.c (providing the chown@@GLIBC_2.1 default version) is replaced by a syscalls.list entry (for powerpc32; powerpc64 has no need for this because of its more recent minimum symbol version, so can just use the entry in sysdeps/unix/syscalls.list), but lchown.S is left as-is because it provides the compat version of chown as an actual alias for __lchown, which is not yet supported by syscalls.list. This file can be removed once such aliases are supported in syscalls.list.

Joseph Myers	68870f1253	Move some setrlimit definitions to syscalls.list (bug 14138). ... Bug 14138 is followup cleanup after removal of support for old Linux kernel versions: moving syscalls to syscalls.list where the only reason for using C definitions was kernel version conditionals that are no longer present. This patch deals with the case of setrlimit (sysdeps/unix/sysv/linux/i386/setrlimit.c, included by various other architectures). Where needed (where there is also a compat symbol for setrlimit@GLIBC_2.0), new syscalls.list entries are added. Where not needed (where there is no such compat symbol and the minimum symbol version for libc is 2.2 or later), no such entries are added as that in sysdeps/unix/syscalls.list will suffice. Thus arm and sh need no such entries, while m68k and powerpc need entries only in a subdirectory syscalls.list file rather than for all configurations that previously used setrlimit.c. (setrlimit@@GLIBC_2.2 and setrlimit@GLIBC_2.0 are now semantically identical - the new symbol version was about a change of types from signed to unsigned and the former compatibility code for dealing with large unsigned arguments on old kernels is no longer needed or present, having been removed with support for pre-2.4 kernels. However, making the two versions into aliases doesn't work at present: the case of having both default and non-default symbol versions on the same syscalls.list line results in a compat_symbol call in code built for static libc, which doesn't compile. I don't suppose it would be hard to generate SHARED conditionals from make-syscalls.sh to fix this, but in any case this patch doesn't make things any worse, as the functions weren't aliases before the patch either.) Tested for x86, and ran ABI tests for ARM as an example of an architecture where the setrlimit.c file was just removed without adding syscalls.list entries.

Joseph Myers	29c4f53e2a	Move architecture shlib-versions files to Linux-specific directories. ... Various architectures have files such as sysdeps/<arch>/shlib-versions whose contents are in fact entirely Linux-specific, relating only to the symbol / shared library versions for the port to Linux on that architecture, when any future port to a different OS on that architecture would use the symbol version of the glibc release it goes in, as standard for new ports. This patch moves such files under sysdeps/unix/sysv/linux/, merging in the contents of sysdeps/<arch>/nptl/shlib-versions in the process. The only bits not moved are those relating to libgcc_s versions, which don't appear OS-specific in the same way that glibc's symbol versions so. It deliberately does not change the regular expressions given for matching configurations in each file; some match only Linux although not Linux-specific, or match other OSes although Linux-specific. It is with a view to at least the following further cleanups: * Move architecture-specific content from the toplevel shlib-versions and nptl/shlib-versions into sysdeps shlib-versions files, so eliminating another difference between ex-ports and non-ex-ports architectures. * Likewise, for OS-specific content in shlib-versions files. * At that point, the first field in shlib-versions files (the regular expression matching a configuration triplet) should be redundant, so eliminate that field and leave shlib-versions selection working purely on a sysdeps basis (with limited use of %ifdef in shlib-versions files when needed) rather than having its own separate mechanism to select what configuration information is relevant. * Move the build of gnu/lib-names.h to a similar mechanism to that used for gnu/stubs.h (each library build installing a version of the header specifically for that build), so we can eliminate the duplication of soname information in the makefiles and get it purely from shlib-versions files again. There may be other cleanups possible as well (in particular, I'm not sure that all cases where the same "Earliest symbol set" information is repeated for many different libraries actually should need to repeat it rather than specifying it just once for DEFAULT for the given configuration, and separately specifying any non-default choices of soname).

Joseph Myers	809fdf0d23	Remove __ASSUME_ATFCTS conditionals in sysdeps/unix/sysv/linux/. ... This patch cleans up for __ASSUME_ATFCTS now always being true for the supported Linux kernel versions by removing conditional code in sysdeps/unix/sysv/linux. Several fchownat.c files that were only present because of differences in the fallback syscalls used (depending on the architecture-specific names of chown-related syscalls for 32-bit uids) are removed. Files that looks like they could be replaced by syscalls.list entries have the standard "Consider moving to syscalls.list." comment (see bug 14138) added. Conditionals on the relevant __NR_* syscall numbers being defined are also removed, since my analysis indicated that the relevant syscalls are always defined for all relevant kernel versions using any affected file. Much of the removed fallback code had unbounded stack allocations, so this reduces the number of cases to consider for anyone reviewing uses of alloca and VLAs in glibc. There remain tests of __ASSUME_ATFCTS in io/openat.c (to determine whether to define __have_atfcts) and sysdeps/posix/getcwd.c (which also uses __have_atfcts); thus, the definition of __ASSUME_ATFCTS remains in kernel-features.h. The logical condition relevant there is whether openat64_not_cancel_3 is known to work. Hurd doesn't use this version of getcwd at all, so the conditionals in getcwd.c are always true in glibc. However, this code is also used in gnulib. So the best way to deal with the conditionals there may be for gnulib people to deal with merging all relevant changes in both directions between the glibc and gnulib versions of this file, at the end of which the openat conditionals should be in whatever form is best for gnulib, and hardcoded in the _LIBC case to having openat supported. Tested by comparing before-and-after disassembly of installed (stripped) shared libraries, on x86_64 and x86. On x86 the patch made no change to the disassembly; on x86_64, the only changes were in readlinkat, where formerly the return value from the readlinkat syscall was stored in an int variable before being converted to ssize_t for the return, and now the return value is returned directly without truncation to int. I think it's clearly correct not to truncate the return value (although I also think the truncation would not have been a user-visible bug because the kernel would never have returned a value it could have affected). * include/fcntl.h (__atfct_seterrno): Remove prototype.

Andi Kleen	8491ed6d70	Add adaptive elision to rwlocks ... This patch relies on the C version of the rwlocks posted earlier. With C rwlocks it is very straight forward to do adaptive elision using TSX. It is based on the infrastructure added earlier for mutexes, but uses its own elision macros. The macros are fairly general purpose and could be used for other elision purposes too. This version is much cleaner than the earlier assembler based version, and in particular implements adaptation which makes it safer. I changed the behavior slightly to not require any changes in the test suite and fully conform to all expected behaviors (generally at the cost of not eliding in various situations). In particular this means the timedlock variants are not elided. Nested trylock aborts.	2014-06-13 13:15:28 -07:00

Joseph Myers	5e7698c6f1	Reduce kernel-features.h duplication. ... This patch reduces duplication between different architectures' kernel-features.h files by making the architecture-independent file define various macros unconditionally (instead of only for a particular list of architectures), with the architecture-specific files then undefining the macros if necessary. Specifically, __ASSUME_O_CLOEXEC (O_CLOEXEC flag to open) and __ASSUME_SOCK_CLOEXEC (SOCK_NONBLOCK and SOCK_CLOEXEC flags to socket) are supported on all architectures as of 2.6.32 or the minimum kernel version for the architecture if later. For __ASSUME_IN_NONBLOCK, __ASSUME_PIPE2, __ASSUME_EVENTFD2, __ASSUME_SIGNALFD4 and __ASSUME_DUP3, the relevant syscalls were added for alpha in 2.6.33 but otherwise the features are available as of 2.6.32. For __ASSUME_UTIMES, support is everywhere in 2.6.32 except for asm-generic architectures and hppa. Although those were the main cases of duplication among kernel-features.h files, some other cases of unnecessary definitions were also cleaned up: the hppa file defined various macros that were either no longer used at all, or defined by the main file by default anyway, the ia64 file had duplicative definitions of __ASSUME_PSELECT and __ASSUME_PPOLL, while mips had such a definition of __ASSUME_IPC64. Really, rather than being defined in the main file then undefined for asm-generic architectures, __ASSUME_UTIMES should become an hppa-specific macro. Given that __ASSUME_ATFCTS and __ASSUME_UTIMENSAT are now always true, the only live __ASSUME_UTIMES conditional is in sysdeps/unix/sysv/linux/utimes.c, which is not used for asm-generic architectures. I think the desired state would be an hppa-specific file (that includes sysdeps/unix/sysv/linux/utimes.c if __ASSUME_UTIMES, and otherwise has fallback code), with the fallback code being removed from the main utimes.c. But I think that's most reasonably a separate cleanup once __ASSUME_ATFCTS and __ASSUME_UTIMESAT have both had conditional code cleaned up. Given this patch, I think it's straightforward to move non-ex-ports architectures to having their own kernel-features.h files, like ex-ports architectures, rather than conditionals in the main file (i.e., such a move won't require the architecture-specific file to contain anything that isn't genuinely architecture-specific), and would encourage architecture maintainers to do so. Tested x86_64 that the installed shared libraries are unchanged by this patch. Note that on some architectures this *will* cause __ASSUME_* macros to be defined in cases where they weren't previously but should have been (but this is just optimization, not a fix to a user-visible bug, so doesn't need a bug report in Bugzilla). * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Define unconditionally.

Joseph Myers	637461d965	Clean up kernel version conditionals for pre-2.6.32 kernels. ... This patch does some initial cleanup, following the move to 2.6.32 minimum kernel version, by removing __LINUX_KERNEL_VERSION conditionals that are now always-true or always-false.

Torvald Riegel	36875b06e0	Fixed and unified pthread_once. ... [BZ #15215] This unifies various pthread_once architecture-specific implementations which were using the same algorithm with slightly different implementations.

Joseph Myers	47c5adebd2	Correct robust mutex / PI futex kernel assumptions (bug 9894). ... This patch continues fixing __ASSUME_* issues in preparation for moving to a 2.6.32 minimum kernel version by addressing assumptions on robust mutex and PI futex support availability. Those assumptions are bug 9894, but to be clear this patch does not address all the issues from that bug about wrong version assumptions, only those still applicable for --enable-kernel=2.6.32 or later (with the expectation that the move to that minimum kernel will obsolete the other parts of the bug). The patch is independent of <https://sourceware.org/ml/libc-alpha/2014-03/msg00585.html>, my other pending-review patch preparing for the kernel version change; the two together complete all the changes I believe are needed in preparation regarding any macro in sysdeps/unix/sysv/linux/kernel-features.h that would be affected by such a change. (I have not checked the correctness of macros whose conditions are unaffected by such a change, or macros only defined in other kernel-features.h files.) As discussed in that bug, robust mutexes and PI futexes need futex_atomic_cmpxchg_inatomic to be implemented, in addition to certain syscalls needed for robust mutexes (and architecture-independent kernel pieces for all the features in question). That is, as I understand it, they need futex_atomic_cmpxchg_inatomic to *work* (not return an ENOSYS error). The issues identified in my analysis relate to ARM, M68K, MicroBlaze, MIPS and SPARC. On ARM, whether futex_atomic_cmpxchg_inatomic works depends on the kernel configuration. As of 3.13, the condition for *not* working is CONFIG_CPU_USE_DOMAINS && CONFIG_SMP. As of 2.6.32 it was simply CONFIG_SMP that meant the feature was not implemented. I don't know if there are any circumstances in which we can say "we can assume a userspace glibc binary built with these options will never run on a kernel with the problematic configuration", but at least for now I'm just undefining the relevant __ASSUME_* macros for ARM. On M68K, two of the three macros are undefined for kernels before 3.10, but as far as I can see __ASSUME_FUTEX_LOCK_PI is in the same group needing futex_atomic_cmpxchg_inatomic support and so should be undefined as well. On MicroBlaze the required support was added in 2.6.33. On MIPS, the support depends on cpu_has_llsc in the kernel - that is, actual hardware LL/SC support (GCC and glibc for MIPS GNU/Linux rely on the instructions being supported in some way, but it may be kernel emulation; futex_atomic_cmpxchg_inatomic doesn't work with that emulation). The same condition as in GCC for indicating LL/SC support may not be available is used for undefining the macros in glibc, __mips == 1 || defined _MIPS_ARCH_R5900. (Maybe we could in fact desupport MIPS processors without the hardware support in glibc.) On SPARC, 32-bit kernels don't support futex_atomic_cmpxchg_inatomic; __arch64__ || __sparc_v9__ is used as the condition for binaries that won't run on 32-bit kernels. This patch is not tested beyond the sanity check of an x86_64 build.

Joseph Myers	acd7f096d7	Complete _BSD_SOURCE / _SVID_source followup cleanup. ... This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. 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.
