2019-08-02	move IPC_STAT definition to a new bits/ipcstat.h file	Rich 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.
2019-07-29	duplicate generic bits/msg.h for each arch using it, in prep to change	Rich Felker	-0/+15

2019-07-29	collapse out byte order conditions in bits/sem.h for fixed-endian archs	Rich Felker	-5/+0
	having preprocessor conditionals on byte order in the bits headers for fixed-endian archs is confusing at best. remove them.
2019-07-29	duplicate generic bits/sem.h for each arch using it, in prep to change	Rich Felker	-0/+16

2019-07-29	remove trailing newlines from various versions of bits/shm.h	Rich Felker	-1/+0

2019-07-29	duplicate generic bits/shm.h for each arch using it, in prep to change	Rich Felker	-0/+28
	there are more archs sharing the generic 64-bit version of the struct, which is uniform and much more reasonable, than sharing the current "generic" one, and depending on how time64 sysvipc is done for 32-bit archs, even more may be sharing the "64-bit version" in the future. so, duplicate the current generic to all archs using it (arm, i386, m68k, microblaze, or1k) so that the generic can be changed freely. this is recorded as its own commit mainly as a hint to git tooling, to assist in copy/move tracking.
2019-07-18	decouple struct stat from kernel type	Rich Felker	-0/+21
	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.
2019-07-01	add new syscall numbers from linux v5.1	Szabolcs Nagy	-0/+39
	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.
2018-07-17	add support for arch-specific ptrace command macros	Szabolcs Nagy	-0/+2
	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).
2018-06-26	add m68k reg.h and user.h	Rich Felker	-0/+78

2018-06-20	fix m68k float.h long double exponent range	Rich Felker	-2/+2
	unlike the x86 variant, the m68k ld80 format allows (biased) exponent zero with mantissa msb set, thereby extending the normal range.
2018-06-20	work around broken kernel struct ipc_perm on some big endian archs	Rich Felker	-0/+1
	the mode member of struct ipc_perm is specified by POSIX to have type mode_t, which is uniformly defined as unsigned int. however, Linux defines it with type __kernel_mode_t, and defines __kernel_mode_t as unsigned short on some archs. since there is a subsequent padding field, treating it as a 32-bit unsigned int works on little endian archs, but the order is backwards on big endian archs with the erroneous definition. since multiple archs are affected, remedy the situation with fixup code in the affected functions (shmctl, semctl, and msgctl) rather than repeating the same shims in syscall_arch.h for every affected arch.
2018-06-19	add m68k port	Rich Felker	-0/+847
	three ABIs are supported: the default with 68881 80-bit fpu format and results returned in floating point registers, softfloat-only with the same format, and coldfire fpu with IEEE single/double only. only the first is tested at all, and only under qemu which has fpu emulation bugs. basic functionality smoke tests have been performed for the most common arch-specific breakage via libc-test and qemu user-level emulation. some sysvipc failures remain, but are shared with other big endian archs and will be fixed separately.
