2022-03-08bits/syscall.h: add landlock syscalls from linux v5.13Szabolcs Nagy-0/+3
see linux commit a49f4f81cb48925e8d7cbd9e59068f516e984144 arch: Wire up Landlock syscalls linuxcommit 17ae69aba89dbfa2139b7f8024b757ab3cc42f59 Merge tag 'landlock_v34' of ... jmorris/linux-security Landlock provides for unprivileged application sandboxing. The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic.
2022-03-08bits/syscall.h: add mount_setattr from linux v5.12Szabolcs Nagy-0/+1
new syscall to change the properties of a mount or a mount tree using file descriptors which the new mount api is based on, see linux commit 2a1867219c7b27f928e2545782b86daaf9ad50bd fs: add mount_setattr()

2021-09-23add SPE FPU support to powerpc-sfRich Felker-1/+1
When the soft-float ABI for PowerPC was added in commit 5a92dd95c77cee81755f1a441ae0b71e3ae2bcdb, with Freescale cpus using the alternative SPE FPU as the main use case, it was noted that we could probably support hard float on them, but that it would involve determining some difficult ABI constraints. This commit is the completion of that work. The Power-Arch-32 ABI supplement defines the ABI profiles, and indeed ATR-SPE is built on ATR-SOFT-FLOAT. But setjmp/longjmp compatibility are problematic for the same reason they're problematic on ARM, where optional float-related parts of the register file are "call-saved if present". This requires testing __hwcap, which is now done. In keeping with the existing powerpc-sf subarch definition, which did not have fenv, the fenv macros are not defined for SPE and the SPEFSCR control register is left (and assumed to start in) the default mode.
2021-07-06fix broken struct shmid_ds on powerpc (32-bit)Rich Felker-1/+1
the kernel structure has padding of the shm_segsz member up to 64 bits, as well as 2 unused longs at the end. somehow that was overlooked when the powerpc port was added, and it has been broken ever since; applications compiled with the wrong definition do not correctly see the shm_segsz, shm_cpid, and shm_lpid members. fixing the definition just by adding the missing padding would break the ABI size of the structure as well as the position of the time64 shm_atime and shm_dtime members we added at the end. instead, just move one of the unused padding members from the original end (before time64) of the structure to the position of the missing padding. this preserves size and preserves correct behavior of any compiled code that was already working. programs affected by the wrong definition need to be recompiled with the correct one.
2021-02-15bits/syscall.h: add process_madvise from linux v5.10Szabolcs Nagy-0/+1
mainly added to linux to allow a central process management service in android to give MADV_COLD|PAGEOUT hints for other processes, see linux commit ecb8ac8b1f146915aa6b96449b66dd48984caacc mm/madvise: introduce process_madvise() syscall: an external memory hinting API

2020-09-09bits/syscall.h: add __NR_faccessat2 from linux v5.8Szabolcs Nagy-0/+1
the linux faccessat syscall lacks a flag argument that is necessary to implement the posix api, see linux commit c8ffd8bcdd28296a198f237cc595148a8d4adfbe vfs: add faccessat2 syscall

2020-03-14define MAP_SYNC on powerpc/powerpc64Samuel Holland-1/+0
Linux defines MAP_SYNC on powerpc and powerpc64 as of commit 22fcea6f85f2 ("mm: move MAP_SYNC to asm-generic/mman-common.h"), so we can stop undefining it on those architectures.
2020-02-05remove legacy time32 timer[fd] syscalls from public syscall.hRich Felker-4/+4
this extends commit 5a105f19b5aae79dd302899e634b6b18b3dcd0d6, removing timer[fd]_settime and timer[fd]_gettime. the timerfd ones are likely to have been used in software that started using them before it could rely on libc exposing functions.
2020-02-05remove further legacy time32 clock syscalls from public syscall.hRich Felker-4/+4
this extends commit 5a105f19b5aae79dd302899e634b6b18b3dcd0d6, removing clock_settime, clock_getres, clock_nanosleep, and settimeofday.
2020-01-30remove legacy clock_gettime and gettimeofday from public syscall.hRich Felker-2/+2
some nontrivial number of applications have historically performed direct syscalls for these operations rather than using the public functions. such usage is invalid now that time_t is 64-bit and these syscalls no longer match the types they are used with, and it was already harmful before (by suppressing use of vdso). since syscall() has no type safety, incorrect usage of these syscalls can't be caught at compile-time. so, without manually inspecting or running additional tools to check sources, the risk of such errors slipping through is high. this patch renames the syscalls on 32-bit archs to clock_gettime32 and gettimeofday_time32, so that applications using the original names will fail to build without being fixed. note that there are a number of other syscalls that may also be unsafe to use directly after the time64 switchover, but (1) these are the main two that seem to be in widespread use, and (2) most of the others continue to have valid usage with a null timeval/timespec argument, as the argument is an optional timeout or similar.
2019-12-30add clone3 syscall number from linux v5.3Szabolcs Nagy-0/+1
the syscall number is reserved on all targets, but it is not wired up on all targets, see linux commit 8f6ccf6159aed1f04c6d179f61f6fb2691261e84 Merge tag 'clone3-v5.3' of ... brauner/linux linux commit 8f3220a806545442f6f26195bc491520f5276e7c arch: wire-up clone3() syscall linux commit 7f192e3cd316ba58c88dfa26796cf77789dd9872 fork: add clone3

2019-11-02move time_t and suseconds_t definitions to common alltypes.h.inRich Felker-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.
2019-11-02move time64 socket options from arch bits to top-level sys/socket.hRich Felker-5/+0
now that all 32-bit archs have 64-bit time types, the values for the time-related socket option macros can be treated as universal for 32-bit archs. the sys/socket.h mechanism for this predates arch/generic and is instead in the top-level header. x32, which does not use the new time64 values of the macros, already has its own overrides, so this commit does not affect it.
2019-11-02switch all existing 32-bit archs to 64-bit time_tRich Felker-25/+40
this commit preserves ABI fully for existing interface boundaries between libc and libc consumers (applications or libraries), by retaining existing symbol names for the legacy 32-bit interfaces and redirecting sources compiled against the new headers to alternate symbol names. this does not necessarily, however, preserve the pairwise ABI of libc consumers with one another; where they use time_t-derived types in their interfaces with one another, it may be necessary to synchronize updates with each other. the intent is that ABI resulting from this commit already be stable and permanent, but it will not be officially so until a release is made. changes to some header-defined types that do not play any role in the ABI between libc and its consumers may still be subject to change. mechanically, the changes made by this commit for each 32-bit arch are as follows: - _REDIR_TIME64 is defined to activate the symbol redirections in public headers - COMPAT_SRC_DIRS is defined in arch.mak to activate build of ABI compat shims to serve as definitions for the original symbol names - time_t and suseconds_t definitions are changed to long long (64-bit) - IPC_STAT definition is changed to add the IPC_TIME64 bit (0x100), triggering conversion of semid_ds, shmid_ds, and msqid_ds split low/high time bits into new time_t members - structs semid_ds, shmid_ds, msqid_ds, and stat are modified to add new 64-bit time_t/timespec members at the end, maintaining existing layout of other members. - socket options (SO_*) and ioctl (sockios) command macros are redefined to use the kernel's "_NEW" values. in addition, on archs where vdso clock_gettime is used, the VDSO_CGT_SYM macro definition in syscall_arch.h is changed to use a new time64 vdso function if available, and a new VDSO_CGT32_SYM macro is added for use as fallback on kernels lacking time64.
2019-11-02move msghdr and cmsghdr out of bits/socket.hRich Felker-16/+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.
2019-10-19use struct pt_regs * rather than void * for powerpc[64] sigcontext regsRich Felker-1/+1
this is to match the kernel and glibc interfaces. here, struct pt_regs is an incomplete type, but that's harmless, and if it's completed by inclusion of another header then members of the struct pointed to by the regs member can be accessed directly without going through a cast or intermediate pointer object.
2019-10-17move pthread types out of per-arch alltypes.hRich Felker-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.
2019-10-17define LONG_MAX via arch alltypes.h, strip down bits/limits.hRich Felker-7/+1
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.
2019-10-17move __BYTE_ORDER definition to alltypes.hRich Felker-15/+2
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.
2019-10-17remove per-arch definitions for va_listRich Felker-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

2019-09-08honor __WCHAR_TYPE__ on archs with legacy long definition of wchar_tRich Felker-0/+4
historically, a number of 32-bit archs used long rather than int for wchar_t, for no good reason. GCC still uses the historical types, but clang replaced them all with int, and it seems PCC uses int too. mismatching the compiler's type for wchar_t is not an option due to wide string literals. note that the mismatch does not affect C++ ABI since wchar_t is its own builtin type/keyword in C++, distinct from both int and long, not a typedef. i386 already worked around this by honoring __WCHAR_TYPE__ if defined by the compiler, and only using the official legacy ABI type if not. add the same to the other affected archs. it might make sense at some point to switch to using int as the default if __WCHAR_TYPE__ is not defined, if the expectations is that new compilers will treat int as the correct choice, but it's unlikely that the case where __WCHAR_TYPE__ is undefined will ever be used anyway. I actually wanted to move the definition of wchar_t to the top-level shared alltypes.h.in, using __WCHAR_TYPE__ and falling back to int if not defined, but that can't be done without assuming all compilers define __WCHAR_TYPE__ thanks to some pathological archs where the ABI has wchar_t as an unsigned type.
2019-08-19fix clash between sys/user.h and kernel ptrace.h on powerpc[64], shRich Felker-6/+4
due to historical accident/sloppiness in glibc, the powerpc, powerpc64, and sh versions of struct user, defined by sys/user.h, used struct pt_regs from the kernel asm/ptrace.h for their regs member. this made it impossible to define the type in an API-compatible manner without either including asm/ptrace.h like glibc does (contrary to our policy of not depending on kernel headers), or clashing with asm/ptrace.h's definition of struct pt_regs if both headers are included (which is almost always the case in software using sys/user.h). for a long time I viewed this problem as having no reasonable fix. I even explored the possibility of having the powerpc[64] and sh versions of user.h just include the kernel header (breaking with policy), but that looked like it might introduce new clashes with sys/ptrace.h. and it would also bring in a lot of additional cruft that makes no sense for sys/user.h to expose. glibc goes out of its way to suppress some of that with #undef, possibly leading to different problems. this is a rabbit-hole that should be explored no further. as it turns out, however, nothing actually uses struct user sufficiently to care about the type of the regs member; most software including sys/user.h does not even use struct user at all. so, the problem can be fixed just by doing away with the insistence on strict glibc API compatibility for the struct tag of the regs member. rather than renaming the tag, which might lead to the new name entering use as API, simply use an untagged structure inside struct user with the same members/layout as struct pt_regs. for sh, struct pt_dspregs is just removed entirely since it was not used.
2019-08-02move IPC_STAT definition to a new bits/ipcstat.h fileRich Felker-0/+1
otherwise, 32-bit archs that could otherwise share the generic bits/ipc.h would need to duplicate the struct ipc_perm definition, obscuring the fact that it's the same. sysvipc is not widely used and these headers are not commonly included, so there is no performance gain to be had by limiting the number of indirectly included files here. files with the existing time32 definition of IPC_STAT are added to all current 32-bit archs now, so that when it's changed the change will show up as a change rather than addition of a new file where it's less obvious that the value is changing vs the generic one that was used before.
2019-07-30move IPC_64 from public bits/ipc.h to syscall_arch.hRich Felker-3/+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.

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).
2018-06-26fix regression in powerpc[64] SO_PEERSEC definitionRich Felker-0/+1
commit 587f5a53bc3a68d80b239ba515d583df690a96df moved the definition of SO_PEERSEC to bits/socket.h for archs where the SO_* macros differ from their standard values, but failed to add copies of the generic definition for powerpc and powerpc64.
2018-06-19powerpc: add pkey syscall numbers from linux v4.16Szabolcs Nagy-0/+3
add pkey_mprotect, pkey_alloc, pkey_free syscall numbers, new in linux commits 3350eb2ea127978319ced883523d828046af4045 and 9499ec1b5e82321829e1c1510bcc37edc20b6f38
2018-03-10fix minor namespace issues in termios.hRich Felker-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.
2018-02-22powerpc: update hwcap.h for linux v4.15Szabolcs Nagy-0/+3
PPC_FEATURE2_HTM_NO_SUSPEND is new in linux commit cba6ac4869e45cc93ac5497024d1d49576e82666 PPC_FEATURE2_DARN and PPC_FEATURE2_SCV were new in v4.12 in commit a4700a26107241cc7b9ac8528b2c6714ff99983d
2018-02-22add MAP_SYNC and MAP_SHARED_VALIDATE from linux v4.15Szabolcs Nagy-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*).
2018-02-22mips,powerpc: fix TIOCSER_TEMT in termios.hSzabolcs Nagy-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.
2017-11-05ioctl TIOCGPTPEER from linux v4.13Szabolcs Nagy-0/+1
added for safe opening of peer end of pty in a mount namespace. new in linux commit c6325179238f1d4683edbec53d8322575d76d7e2
2017-11-05add statx syscall numbers from linux v4.11Szabolcs Nagy-0/+1
statx was added in linux commit a528d35e8bfcc521d7cb70aaf03e1bd296c8493f (there is no libc wrapper yet and microblaze and sh misses the number).
