* fix wrong sigaction syscall ABI on mips*, or1k, microblaze, riscv64Rich Felker2023-02-092-2/+1
| | | | | | | | | | | | | | | | | | | | | we wrongly defined a dummy SA_RESTORER flag on these archs, despite the kernel interface not actually having such a feature. on archs which lack SA_RESTORER, the kernel sigaction structure also lacks the restorer function pointer member, which means the signal mask appears at a different offset. the kernel was thereby interpreting the bits of the code address as part of the signal set to be masked while handling the signal. this patch removes the erroneous SA_RESTORER definitions from archs which do not have it, makes access to the member conditional on whether SA_RESTORER is defined for the arch, and removes the now-unused asm for the affected archs. because there are reportedly versions of qemu-user which also use the wrong ABI here, the old ksigaction struct size is preserved with an unused member at the end. this is harmless and mitigates the risk of such a bug turning into a buffer overflow onto the sigaction function's stack.
* fix debugger tracking of shared libraries on mips with PIE main programRich Felker2023-01-181-0/+1
| | | | | | | | mips has its own mechanisms for DT_DEBUG because it makes _DYNAMIC read-only, and the original mechanism, DT_MIPS_RLD_MAP, was PIE-incompatible. DT_MIPS_RLD_MAP_REL was added to remedy this, but we never implemented support for it. add it now using the same idioms for mips-specific ldso logic.
* bits/syscall.h: add landlock syscalls from linux v5.13Szabolcs Nagy2022-03-081-0/+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.
* bits/syscall.h: add mount_setattr from linux v5.12Szabolcs Nagy2022-03-081-0/+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()

* bits/syscall.h: add process_madvise from linux v5.10Szabolcs Nagy2021-02-151-0/+1

* bits/syscall.h: add __NR_faccessat2 from linux v5.8Szabolcs Nagy2020-09-091-0/+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
* add pidfd_getfd and openat2 syscall numbers from linux v5.6Szabolcs Nagy2020-09-091-0/+2
| | | | | | | | | | | | | | | | | | | also added clone3 on sh and m68k, on sh it's still missing (not yet wired up), but reserved so safe to add. see linux commit fddb5d430ad9fa91b49b1d34d0202ffe2fa0e179 open: introduce openat2(2) syscall linux commit 9a2cef09c801de54feecd912303ace5c27237f12 arch: wire up pidfd_getfd syscall linux commit 8649c322f75c96e7ced2fec201e123b2b073bf09 pid: Implement pidfd_getfd syscall linux commit e8bb2a2a1d51511e6b3f7e08125d52ec73c11139 m68k: Wire up clone3() syscall
* fix missing O_LARGEFILE values on x86_64, x32, and mips64Rich Felker2020-09-031-1/+1
| | | | | | | | | | | | | | | | | prior to commit 685e40bb09f5f24a2af54ea09c97328808f76990, x86_64 was correctly passing O_LARGEFILE to SYS_open; it was removed (defined to 0 in the public header, and changed to use the public definition) as part of that change, probably out of a mistaken belief that it's not needed. however, on a mixed system with 32-bit and 64-bit binaries, it's important that all files be opened with O_LARGEFILE, even if the opening process is 64-bit, in case a descriptor is passed to a 32-bit process. otherwise, attempts to access past 2GB in the 32-bit process could produce EOVERFLOW. most 64-bit archs added later got this right alread, except for mips64. x32 was also affected. there are now fixed.
* deduplicate __pthread_self thread pointer adjustment out of each archRich Felker2020-08-271-4/+4
| | | | | | | | | | | | | | | | the adjustment made is entirely a function of TLS_ABOVE_TP and TP_OFFSET. aside from avoiding repetition of the TP_OFFSET value and arithmetic, this change makes pthread_arch.h independent of the definition of struct __pthread from pthread_impl.h. this in turn will allow inclusion of pthread_arch.h to be moved to the top of pthread_impl.h so that it can influence the definition of the structure. previously, arch files were very inconsistent about the type used for the thread pointer. this change unifies the new __get_tp interface to always use uintptr_t, which is the most correct when performing arithmetic that may involve addresses outside the actual pointed-to object (due to TP_OFFSET).
* deduplicate TP_ADJ logic out of each arch, replace with TP_OFFSETRich Felker2020-08-241-1/+1
| | | | | | the only part of TP_ADJ that was not uniquely determined by TLS_ABOVE_TP was the 0x7000 adjustment used mainly on mips and powerpc variants.
* fix incorrect SIGSTKFLT on all mips archsRich Felker2020-05-211-1/+1
| | | | | | signal 7 is SIGEMT on Linux mips* ABI according to the man pages and kernel. it's not clear where the wrong name came from but it dates back to original mips commit.
* work around negated error code bug on some mips kernelsRich Felker2020-03-141-7/+7
| | | | | | | | | | | | on all mips variants, Linux did (and maybe still does) have some syscall return paths that wrongly return both the error flag in r7 and a negated error code in r2. in particular this happened for at least some causes of ENOSYS. add an extra check to only negate the error code if it's positive to begin with. bug report and concept for patch by Andreas Dröscher.
* revert mips64/n32 syscall asm clean-up due to regressionsRich Felker2020-03-141-28/+28
| | | | | | | | | | | | | | | | | | | | | | effectivly revert commit ddc7c4f936c7a90781072f10dbaa122007e939d0 which was wrong; it caused a major regression on Linux versions prior to 2.6.36. old kernels did not properly preserve r2 across syscall restart, and instead restarted with the instruction right before syscall, imposing a contract that the previous instruction must load r2 from an immediate or a register (or memory) not clobbered by the syscall. since other changes were made since, including removal of the struct stat conversion that was replaced by separate struct kstat, this is not a direct revert, only a functional one. the "0"(r2) input constraint added back seems useless/erroneous, but without it most gcc versions (seems to be all prior to 9.x) fail to honor the output register binding for r2. this seems to be a variant of gcc bug #87733. further changes should be made later if a better workaround is found, but this one has been working since 2012. it seems this issue was encountered but misidentified then, when it inspired commit 4221f154ff29ab0d6be1e7beaa5ea2d1731bc58e.
* 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

* fix build regression on mips64 due to endian.h removalRich Felker2019-11-051-0/+2
| | | | | | | | | | | | | | | | commit 4d3a162d001a93edd285fb6603a883c30ae553ba overlooked that the mips64 reloc.h dependent on endian.h not only for setting the ABI ldso name to match the byte order, but also for use of the byte swapping macros. they are needed to override R_TYPE, R_SYM, and R_INFO, to compensate for a mips "quirk" of always using big endian order for symbol references in relocations. part of that commit canot be reverted because the original code was wrong: it's invalid to define _GNU_SOURCE or any feature test macro in reloc.h, or anywhere except at the top of a source file. however, thanks to commit 316730cdc7a330cddf288b4e5c1de5daa64e19f4, the feature test macro is no longer needed to access the endian-swapping macros, so simply bringing back the #include directive suffices.
* 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 use of endian.h from arch reloc.h headers, clean upRich Felker2019-10-171-8/+0
| | | | | | | | | | building on commit 97d35a552ec5b6ddf7923dd2f9a8eb973526acea, __BYTE_ORDER is now available wherever alltypes.h is included. since reloc.h is only used from src/internal/dynlink.h, it can be assumed that __BYTE_ORDER is exposed. reloc.h is not permitted to be included in other contexts, and generally, like most arch headers, lacks inclusion guards that would allow such usage. the mips64 version mistakenly included such guards; they are removed for consistency.
* 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
* fix mips r6 syscall clobber lists not to include hi/lo registersRich Felker2019-09-261-0/+6
| | | | | | | | | | mips r6 (an incompatible isa from traditional mips) removes the hi and lo registers used for mul/div results. older gcc versions accepted them in the clobber list for asm, but their presence is incorrect and breaks on later versions. in the process of fixing this, the clobber list for 32-bit mips syscalls has been deduplicated via a macro like on mips64 and n32.
* 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]
* get/setsockopt: add fallback for new time64 SO_RCVTIMEO/SO_SNDTIMEORich Felker2019-07-311-0/+3
| | | | | | | | | | without this, the SO_RCVTIMEO and SO_SNDTIMEO socket options would stop working on pre-5.1 kernels after time_t is switched to 64-bit and their values are changed to the new time64 versions. new code is written such that it's statically unreachable on 64-bit archs, and on existing 32-bit archs until the macro values are changed to activate 64-bit time_t.
* 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 mips/n32/64 stat struct hacks from syscall machineryRich Felker2019-07-182-134/+17
| | | | | | now that we have a kstat structure decoupled from the public struct stat, we can just use the broken kernel structures directly and let the code in fstatat do the translation.
* decouple struct stat from kernel typeRich Felker2019-07-181-0/+23
| | | | | | | | | | | | | | | presently, all archs/ABIs have struct stat matching the kernel stat[64] type, except mips/mipsn32/mips64 which do conversion hacks in syscall_arch.h to work around bugs in the kernel type. this patch completely decouples them and adds a translation step to the success path of fstatat. at present, this is just a gratuitous copying, but it opens up multiple possibilities for future support for 64-bit time_t on 32-bit archs and for cleaned-up/unified ABIs. for clarity, the mips hacks are not yet removed in this commit, so the mips kstat structs still correspond to the output of the hacks in their syscall_arch.h files, not the raw kernel type. a subsequent commit will fix this.
* 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.
* clean up mips64/n32 syscall asm constraintsRich Felker2019-07-161-27/+28
| | | | | | | | | | | | | | | | | ever since inline syscalls were added for (o32) mips in commit 328810d32524e4928fec50b57e37e1bf330b2e40, the asm has nonsensically loaded the syscall number, rather than taking $2 as an input constraint to let the compiler load it. commit cfc09b1ecf0c6981494fd73dffe234416f66af10 improved on this somewhat by allowing a constant syscall number to propagate into an immediate, but missed that the whole operation made no sense. now, only $4, $5, $6, $8, and $9 are potential input-only registers. $2 is always input and output, and $7 is both when it's an argument, otherwise output-only. previously, $7 was treated as an input (with a "1" constraint matching its output position) even when it was not an input, which was arguably undefined behavior (asm input from indeterminate value). this is corrected.
* deduplicate mips64/n32 syscall clobbered register listsRich Felker2019-07-161-14/+11
| | | | | | | | | | | | | | this patch is not purely non-functional changes, since before, $8 and $9 were wrongly in the clobberlist for syscalls with fewer than 5 or 6 arguments. of course it's impossible for syscalls to have different clobbers depending on their number of arguments. the clobberlist for the recently-added 5- and 6-argument forms was correct, and for the 0- to 4-argument forms was erroneously copied from the mips o32 ABI where the additional arguments had to be passed on the stack. in making this change, I reviewed the kernel sources, and $8 and $9 are always saved for 64-bit kernels since they're part of the syscall argument list for n32 and n64 ABIs.
* 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.
* implement inline 5- and 6-argument syscalls for mipsn32 and mips64Rich Felker2019-04-101-23/+43
| | | | | | | | | | n32 and n64 ABIs add new argument registers vs o32, so that passing on the stack is not necessary, so it's not clear why the 5- and 6-argument versions were special-cased to begin with; it seems to have been pattern-copying from arch/mips (o32). i've treated the new argument registers like the first 4 in terms of clobber status (non-clobbered). hopefully this is correct.
