* mips: add clone3 syscall numbers from linux v5.4Szabolcs Nagy2019-12-301-0/+1
| | | | | | | the syscall numbers were reserved in v5.3 but not wired up on mips, see linux commit 0671c5b84e9e0a6d42d22da9b5d093787ac1c5f3 MIPS: Wire up clone3 syscall
* add pidfd_open syscall number from linux v5.3Szabolcs Nagy2019-12-301-0/+1
| | | | | | | | | | see linux commit 7615d9e1780e26e0178c93c55b73309a5dc093d7 arch: wire-up pidfd_open() linux commit 32fcb426ec001cb6d5a4a195091a8486ea77e2df pid: add pidfd_open()
* move time_t and suseconds_t definitions to common alltypes.h.inRich Felker2019-11-021-3/+0
| | | | | | | now that all 32-bit archs have 64-bit time_t (and suseconds_t), the arch-provided _Int64 macro (long or long long, as appropriate) can be used to define them, and arch-specific definitions are no longer needed.
* move msghdr and cmsghdr out of bits/socket.hRich Felker2019-11-021-32/+0
| | | | | | | | | | | | | | | these structures can now be defined generically in terms of endianness and long size. previously, the 32-bit archs all shared a common definition from the generic bits header, and each 64-bit arch had to repeat the 64-bit version, with endian conditionals if the arch had variants of each endianness. I would prefer getting rid of the preprocessor conditionals for padding and instead using unnamed bitfield members, like commit 9b2921bea1d5017832e1b45d1fd64220047a9802 did for struct timespec. however, at present sendmsg, recvmsg, and recvmmsg need access to the padding members by name to zero them. this could perhaps be cleaned up in the future.
* move pthread types out of per-arch alltypes.hRich Felker2019-10-171-8/+0
| | | | | | | | | | | policy has long been that these definitions are purely a function of whether long/pointer is 32- or 64-bit, and that they are not allowed to vary per-arch. move the definition to the shared alltypes.h.in fragment, using integer constant expressions in terms of sizeof to vary the array dimensions appropriately. I'm not sure whether this is more or less ugly than using preprocessor conditionals and two sets of definitions here, but either way is a lot less ugly than repeating the same thing for every arch.
* define LONG_MAX via arch alltypes.h, strip down bits/limits.hRich Felker2019-10-172-7/+2
| | | | | | | | | | | | | | | | | | | | | LLONG_MAX is uniform for all archs we support and plenty of header and code level logic assumes it is, so it does not make sense for limits.h bits mechanism to pretend it's variable. LONG_BIT can be defined in terms of LONG_MAX; there's no reason to put it in bits. by moving LONG_MAX definition to __LONG_MAX in alltypes.h and moving LLONG_MAX out of bits, there are now no plain-C limits that are defined in the bits header, so the bits header only needs to be included in the POSIX or extended profiles. this allows the feature test macro logic to be removed from the bits header, facilitating a long-term goal of getting such logic out of bits. having __LONG_MAX in alltypes.h will allow further generalization of headers. archs without a constant PAGESIZE no longer need bits/limits.h at all.
* remove indirect use of endian.h from public headersRich Felker2019-10-171-2/+0
| | | | | | | | building on commit 97d35a552ec5b6ddf7923dd2f9a8eb973526acea, __BYTE_ORDER is now available wherever alltypes.h is included. endian.h should not be used since, in the future, it will expose identifiers that are not in the reserved namespace for the headers which were previously using it.
* move __BYTE_ORDER definition to alltypes.hRich Felker2019-10-172-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | this change is motivated by the intersection of several factors. presently, despite being a nonstandard header, endian.h is exposing the unprefixed byte order macros and functions only if _BSD_SOURCE or _GNU_SOURCE is defined. this is to accommodate use of endian.h from other headers, including bits headers, which need to define structure layout in terms of endianness. with time64 switch-over, even more headers will need to do this. at the same time, the resolution of Austin Group issue 162 makes endian.h a standard header for POSIX-future, requiring that it expose the unprefixed macros and the functions even in standards-conforming profiles. changes to meet this new requirement would break existing internal usage of endian.h by causing it to violate namespace where it's used. instead, have the arch's alltypes.h define __BYTE_ORDER, either as a fixed constant or depending on the right arch-specific predefined macros for determining endianness. explicit literals 1234 and 4321 are used instead of __LITTLE_ENDIAN and __BIG_ENDIAN so that there's no danger of getting the wrong result if a macro is undefined and implicitly evaluates to 0 at the preprocessor level. the powerpc (32-bit) bits/endian.h being removed had logic for varying endianness, but our powerpc arch has never supported that and has always been big-endian-only. this logic is not carried over to the new __BYTE_ORDER definition in alltypes.h.
* remove per-arch definitions for va_listRich Felker2019-10-171-3/+0
| | | | | | | now that commit f7f1079796abc6f97c69521d2334e9c7d3945dd8 removed the legacy i386 conditional definition, va_list is in no way arch-specific, and has no reason to be in the future. move it to the shared part of alltypes.h.in
* add new syscall numbers from linux v5.2Szabolcs Nagy2019-09-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | new mount api syscalls were added, same numers on all targets, see linux commit a07b20004793d8926f78d63eb5980559f7813404 vfs: syscall: Add open_tree(2) to reference or clone a mount linux commit 2db154b3ea8e14b04fee23e3fdfd5e9d17fbc6ae vfs: syscall: Add move_mount(2) to move mounts around linux commit 24dcb3d90a1f67fe08c68a004af37df059d74005 vfs: syscall: Add fsopen() to prepare for superblock creation linux commit ecdab150fddb42fe6a739335257949220033b782 vfs: syscall: Add fsconfig() for configuring and managing a context linux commit 93766fbd2696c2c4453dd8e1070977e9cd4e6b6d vfs: syscall: Add fsmount() to create a mount for a superblock linux commit cf3cba4a429be43e5527a3f78859b1bfd9ebc5fb vfs: syscall: Add fspick() to select a superblock for reconfiguration linux commit 9c8ad7a2ff0bfe58f019ec0abc1fb965114dde7d uapi, x86: Fix the syscall numbering of the mount API syscalls [ver #2] linux commit d8076bdb56af5e5918376cd1573a6b0007fc1a89 uapi: Wire up the mount API syscalls on non-x86 arches [ver #2]
* move IPC_64 from public bits/ipc.h to syscall_arch.hRich Felker2019-07-301-2/+0
| | | | | | | | | | | | | | | | | | | | the definition of the IPC_64 macro controls the interface between libc and the kernel through syscalls; it's not a public API. the meaning is rather obscure. long ago, Linux's sysvipc *id_ds structures used 16-bit uids/gids and wrong types for a few other fields. this was in the libc5 era, before glibc. the IPC_64 flag (64 is a misnomer; it's more like 32) tells the kernel to use the modern[-ish] versions of the structures. the definition of IPC_64 has nothing to do with whether the arch is 32- or 64-bit. rather, due to either historical accident or intentional obnoxiousness, the kernel only accepts and masks off the 0x100 IPC_64 flag conditional on CONFIG_ARCH_WANT_IPC_PARSE_VERSION, i.e. for archs that want to provide, or that accidentally provided, both. for archs which don't define this option, no masking is performed and commands with the 0x100 bit set will fail as invalid. so ultimately, the definition is just a matter of matching an arbitrary switch defined per-arch in the kernel.
* remove duplicates of new generic bits/msg.hRich Felker2019-07-291-13/+0
|
* remove duplicates of new generic bits/sem.hRich Felker2019-07-291-14/+0
| | | | | | some of these were not exact duplicates, but had gratuitously different naming for padding, or omitted the endian checks because the arch is fixed-endian.
* extricate bits/sem.h from x32 time_t hackRich Felker2019-07-291-4/+4
| | | | | | | | | | | | | | various padding fields in the generic bits/sem.h were defined in terms of time_t as a cheap hack standing in for "kernel long", to allow x32 to use the generic version of the file. this was a really bad idea, as it ended up getting copied into lots of arch-specific versions of the bits file, and is a blocker to changing time_t to 64-bit on 32-bit archs. this commit adds an x32-specific version of the header, and changes padding type back from time_t to long (currently the same type on all archs but x32) in the generic header and all the others the hack got copied into.
* remove duplicates of new generic bits/shm.hRich Felker2019-07-291-24/+0
|
* remove utterly wrong includes from mips64/n32 bits/stat.hRich Felker2019-07-181-3/+0
| | | | | | | | these were overlooked during review. bits headers are not allowed to pull in additional headers (note: that rule is currently broken in other places but just for endian.h). string.h has no place here anyway, and including bits/alltypes.h without defining macros to request types from it is a nop.
* fix conflicting mips and powerpc definitions for TIOCSER_TEMT macroSamuel Holland2019-07-101-1/+1
| | | | | | | | Commit 3517d74a5e04a377192d1f4882ad6c8dc22ce69a changed the token in sys/ioctl.h from 0x01 to 1, so bits/termios.h no longer matches. Revert the bits/termios.h change to keep the headers in sync. This reverts commit 9eda4dc69c33852c97c6f69176bf45ffc80b522f.
* add new syscall numbers from linux v5.1Szabolcs Nagy2019-07-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | syscall numbers are now synced up across targets (starting from 403 the numbers are the same on all targets other than an arch specific offset) IPC syscalls sem*, shm*, msg* got added where they were missing (except for semop: only semtimedop got added), the new semctl, shmctl, msgctl imply IPC_64, see linux commit 0d6040d4681735dfc47565de288525de405a5c99 arch: add split IPC system calls where needed new 64bit time_t syscall variants got added on 32bit targets, see linux commit 48166e6ea47d23984f0b481ca199250e1ce0730a y2038: add 64-bit time_t syscalls to all 32-bit architectures new async io syscalls got added, see linux commit 2b188cc1bb857a9d4701ae59aa7768b5124e262e Add io_uring IO interface linux commit edafccee56ff31678a091ddb7219aba9b28bc3cb io_uring: add support for pre-mapped user IO buffers a new syscall got added that uses the fd of /proc/<pid> as a stable handle for processes: allows sending signals without pid reuse issues, intended to eventually replace rt_sigqueueinfo, kill, tgkill and rt_tgsigqueueinfo, see linux commit 3eb39f47934f9d5a3027fe00d906a45fe3a15fad signal: add pidfd_send_signal() syscall on some targets (arm, m68k, s390x, sh) some previously missing syscall numbers got added as well.
* mips64: fix syscall numbers of io_pgetevents and rseqSzabolcs Nagy2019-07-011-2/+2
| | | | | | | | | the numbers added in commit d149e69c02eb558114f20ea718810e95538a3b2f add io_pgetevents and rseq syscall numbers from linux v4.18 were incorrect.

* add io_pgetevents and rseq syscall numbers from linux v4.18Szabolcs Nagy2018-12-091-0/+2
| | | | | | | | io_pgetevents is new in linux commit 7a074e96dee62586c935c80cecd931431bfdd0be rseq is new in linux commit d7822b1e24f2df5df98c76f0e94a5416349ff759
* add support for arch-specific ptrace command macrosSzabolcs Nagy2018-07-171-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | sys/ptrace.h is target specific, use bits/ptrace.h to add target specific macro definitions. these macros are kept in the generic sys/ptrace.h even though some targets don't support them: PTRACE_GETREGS PTRACE_SETREGS PTRACE_GETFPREGS PTRACE_SETFPREGS PTRACE_GETFPXREGS PTRACE_SETFPXREGS so no macro definition got removed in this patch on any target. only s390x has a numerically conflicting macro definition (PTRACE_SINGLEBLOCK). the PT_ aliases follow glibc headers, otherwise the definitions come from linux uapi headers except ones that are skipped in glibc and there is no real kernel support (s390x PTRACE_*_AREA) or need special type definitions (mips PTRACE_*_WATCH_*) or only relevant for linux 2.4 compatibility (PTRACE_OLDSETOPTIONS).
* fix value of SO_PEERSEC on mips archsRich Felker2018-06-261-0/+1
| | | | adapted from patch by Matthias Schiffer.
* mips: add HWCAP_ flags from linux v4.17Szabolcs Nagy2018-06-191-0/+1
| | | | new in linux commit 256211f2b0b251e532d1899b115e374feb16fa7a
* fix minor namespace issues in termios.hRich Felker2018-03-101-0/+2
| | | | | | | | | | the output delay features (NL*, CR*, TAB*, BS*, and VT*) are XSI-shaded. VT* is in the V* namespace reservation but the rest need to be suppressed in base POSIX namespace. unfortunately this change introduces feature test macro checks into another bits header. at some point these checks should be simplified by having features.h handle the "FTM X implies Y" relationships.
* add MAP_SYNC and MAP_SHARED_VALIDATE from linux v4.15Szabolcs Nagy2018-02-221-0/+1
| | | | | | | | for synchronous page faults, new in linux commit 1c9725974074a047f6080eecc62c50a8e840d050 and b6fb293f2497a9841d94f6b57bd2bb2cd222da43 note that only targets that use asm-generic/mman.h have this new flag defined, so undef it on other targets (mips*, powerpc*).
* mips,powerpc: fix TIOCSER_TEMT in termios.hSzabolcs Nagy2018-02-221-1/+1
| | | | | | use the same token to define TIOCSER_TEMT as is used in ioctl.h so when both headers are included there are no redefinition warnings during musl build.
* ioctl TIOCGPTPEER from linux v4.13Szabolcs Nagy2017-11-051-0/+1
| | | | | added for safe opening of peer end of pty in a mount namespace. new in linux commit c6325179238f1d4683edbec53d8322575d76d7e2
* add statx syscall numbers from linux v4.11Szabolcs Nagy2017-11-051-0/+1
| | | | | statx was added in linux commit a528d35e8bfcc521d7cb70aaf03e1bd296c8493f (there is no libc wrapper yet and microblaze and sh misses the number).
* add SIOCGSTAMPNS socket ioctl macro to ioctl.hSzabolcs Nagy2017-08-291-0/+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.)
* fix mips ioctl macros to match linux asm/sockios.hSzabolcs Nagy2017-08-291-5/+5
|
* add pkey_{mprotect,alloc,free} syscalls from linux v4.9Szabolcs Nagy2016-12-291-0/+3
| | | | | see linux commit e8c24d3a23a469f1f40d4de24d872ca7023ced0a and linux Documentation/x86/protection-keys.txt
* add bits/hwcap.h and include it in sys/auxv.hSzabolcs Nagy2016-10-201-0/+2
| | | | | | | | | 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.
* fix regression in tcsetattr on all mips archsRich Felker2016-07-131-3/+3
| | | | | revert commit 8c316e9e49d37ad92c2e7493e16166a2afca419f. it was wrong and does not match how the kernel API works.
* fix TCS* definitions in mips termios.hSzabolcs Nagy2016-07-031-3/+3
| | | | these were incorrectly using the generic definitions.
* fix mips termios.h macro exposure/namespace issuesSzabolcs Nagy2016-07-031-15/+14
| | | | same changes to the defined macros as in powerpc and generic bits.
* fix TIOCMSET in mips ioctl.hSzabolcs Nagy2016-07-031-1/+1
| | | | it seems it was a typo.
* fix mips, mips64, mipsn32 TIOCM_* macros in ioctl.hSzabolcs Nagy2016-07-031-14/+14
| | | | | TIOCM_ macros were wrongly using the asm-generic/termios.h definitions instead of the mips specific ones from asm/termios.h
* remove mips and powerpc ioctls that are missing from linux uapiSzabolcs Nagy2016-07-031-5/+0
| | | | | | mips and powerpc use their own asm/ioctls.h, not the asm-generic/ioctls.h and they lack termiox macros that are available on other targets. see kernel commit 1d65b4a088de407e99714fdc27862449db04fb5c
* add missing TIOC* macros to ioctl.hSzabolcs Nagy2016-07-031-0/+8
| | | | | these are defined in linux asm/ioctls.h. (powerpc64 and powerpc bits/ioctl.h are now identical)
* add missing SIOCSIFNAME from linux/sockios.h to ioctl.hSzabolcs Nagy2016-07-031-0/+1
| | | | glibc ioctl.h has it too.
* remove ioctl macros that were removed from linux uapiSzabolcs Nagy2016-07-031-4/+0
| | | | | TIOCTTYGSTRUCT, TIOCGHAYESESP, TIOCSHAYESESP and TIOCM_MODEM_BITS were removed from the linux uapi and not present in glibc ioctl.h
* add consistent reserved fields in mips64/n32 termios structuresRich Felker2016-07-031-0/+2
| | | | | | | | | | | | | | | | | | the (unused) speed fields were omitted when these ports were first added (within this release cycle, so not present in any release yet) in accordance with how glibc defines the structure on mips archs. however their omission does not match existing musl practice/intent. glibc provides its own, mostly-unified termios structure definition and performs translation in userspace to match the kernel structure for the arch, but has gratuitous differences on a few archs like mips, presumably as a result of historical mistakes. some other libcs use the kernel definitions directly. musl essentially does that, by matching the kernel layout in the part of the structure the kernel will read/write, but leaves additional space at the end for extensibility. these are nominally the (nonstandard) speed fields and (on most archs) extra c_cc elements, but since they are not used they could be repurposed if there's ever a need.
* add preadv2 and pwritev2 syscall numbers for linux v4.6Szabolcs Nagy2016-06-091-0/+2
| | | | | | | | the syscalls take an additional flag argument, they were added in commit f17d8b35452cab31a70d224964cd583fb2845449 and a RWF_HIPRI priority hint flag was added to linux/fs.h in 97be7ebe53915af504fb491fb99f064c7cf3cb09. the syscall is not allocated for microblaze and sh yet.
* deduplicate __NR_* and SYS_* syscall number definitionsBobby Bingham2016-05-121-320/+0
|
* add copy_file_range syscall numbers from linux v4.5Szabolcs Nagy2016-03-191-0/+2
| | | | | | | it was introduced for offloading copying between regular files in linux commit 29732938a6289a15e907da234d6692a2ead71855 (microblaze and sh does not yet have the syscall number.)
* mips64: add recent linux syscall numbersSzabolcs Nagy2016-03-191-0/+6
| | | | add userfaultfd, membarrier and mlock2 system call numbers.
* deduplicate bits/mman.hSzabolcs Nagy2016-03-181-45/+11
| | | | | | | | | | | 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.
* add mips64 portRich Felker2016-03-0626-0/+1721
