2017-08-29add SIOCGSTAMPNS socket ioctl macro to ioctl.hSzabolcs Nagy-0/+1
it is defined in linux asm/sockios.h since commit ae40eb1ef30ab4120bd3c8b7e3da99ee53d27a23 (linux v2.6.22) but was missing from musl by accident. in musl the sockios macros are exposed in sys/ioctl.h together with other ioctl requests instead of in sys/socket.h because of namespace rules. (glibc has them in sys/socket.h under _GNU_SOURCE.)
2016-12-15remove legacy i386 fallback stdarg implementation and frameworkRich Felker-4/+0
this has been slated for removal for a long time. there is fundamentally no way to implement stdarg without compiler assistance; any attempt to do so has serious undefined behavior; its working depends not just (as a common misconception goes) on ABI, but also on assumptions about compiler code generation internal to a translation unit, which is not subject to external ABI constraints.
2016-11-11generalize ELF hash table types not to assume 32-bit entriesRich Felker-0/+1
alpha and s390x gratuitously use 64-bit entries (wasting 2x space and cache utilization) despite the values always being 32-bit. based on patch by Bobby Bingham, with changes suggested by Alexander Monakov to use the public Elf_Symndx type from link.h (and make it properly variable by arch) rather than adding new internal infrastructure for handling the type.
2016-10-20add bits/hwcap.h and include it in sys/auxv.hSzabolcs Nagy-0/+0
aarch64, arm, mips, mips64, mipsn32, powerpc, powerpc64 and sh have cpu feature bits defined in linux for AT_HWCAP auxv entry, so expose those in sys/auxv.h it seems the mips hwcaps were never exposed to userspace neither by linux nor by glibc, but that's most likely an oversight.
2016-07-03make brace placement in public header struct definitions consistentRich Felker-12/+6
placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch/*/bits -name '*.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives.
2016-07-03fix generic termios.h macro exposure/namespace issuesSzabolcs Nagy-9/+14
add EXTA, EXTB, CIBAUD, CMSPAR, XCASE macros and hide them as well as CBAUD, ECHOCTL, ECHOPRT, ECHOKE, FLUSHO, PENDIN in standard mode. the new macros are both in glibc termios.h and in linux asm/termbits.h, the later also contains IBSHIFT and BOTHER, those were not added. these are not standard macros, but some of them are in the reserved namespace so could be exposed, the ones which are not reserved are CIBAUD, CMSPAR and XCASE (which was removed in issue 6), the rest got hidden to be consistent with glibc.
2016-07-03fix FIOQSIZE in arm ioctl.hSzabolcs Nagy-0/+2
arm ioctl.h is the same as the generic one except this macro, so a workaround solution is used to avoid another ioctl.h copy.
2016-07-03add missing TIOC* macros to ioctl.hSzabolcs Nagy-0/+8
these are defined in linux asm/ioctls.h. (powerpc64 and powerpc bits/ioctl.h are now identical)
2016-07-03add missing SIOCSIFNAME from linux/sockios.h to ioctl.hSzabolcs Nagy-0/+1
glibc ioctl.h has it too.
2016-07-03remove ioctl macros that were removed from linux uapiSzabolcs Nagy-4/+0
TIOCTTYGSTRUCT, TIOCGHAYESESP, TIOCSHAYESESP and TIOCM_MODEM_BITS were removed from the linux uapi and not present in glibc ioctl.h
2016-03-18deduplicate bits/mman.hSzabolcs Nagy-0/+0
currently five targets use the same mman.h constants and the rest share most constants too, so move them to sys/mman.h before the bits/mman.h include where the differences can be corrected by redefinition of the macros. this fixes two minor bugs: POSIX_MADV_DONTNEED was wrong on most targets (it should be the same as MADV_DONTNEED), and sh defined the x86-only MAP_32BIT mmap flag.
2016-01-27deduplicate the bulk of the arch bits headersRich Felker-0/+644
all bits headers that were identical for a number of 'clean' archs are moved to the new arch/generic tree. in addition, a few headers that differed only cosmetically from the new generic version are removed. additional deduplication may be possible in mman.h and in several headers (limits.h, posix.h, stdint.h) that mostly depend on whether the arch is 32- or 64-bit, but they are left alone for now because greater gains are likely possible with more invasive changes to header logic, which is beyond the scope of this commit.
