2012-02-07fix typo in inotify.hRich Felker-1/+1
2012-02-01apparently gnu caddr_t is supposed to be char *, not unsigned longRich Felker-1/+1
this type should never be used anyway, but some old junk uses it..
2012-01-28add linux setfs[ug]id syscall wrappersRich Felker-0/+20
patch by Jeremy Huntwork
2012-01-26remove useless "extern" keywords in headersRich Felker-1/+1
2012-01-24add MIN/MAX macros to sys/param.hRich Felker-0/+5
this is a nonstandard junk header anyway, so just do what apps expect..
2012-01-24add legacy futimes and lutimes functionsRich Felker-0/+2
based on patch by sh4rm4. these functions are deprecated; futimens and utimensat should be used instead in new programs.
2012-01-20add prlimit syscall wrapperRich Felker-0/+8
2011-11-10fix all missing instances of __cplusplus checks/extern "C" in headersRich Felker-0/+95
patch by Arvid Picciani (aep)
2011-10-17fix some details in ugly stuff that doesn't belong in libcRich Felker-0/+2
patches by sh4rm4, presumably needed to make gdb or some similar junk happy...
2011-09-26cleanup various minor issues reported by nszRich Felker-1/+1
the changes to syscall_ret are mostly no-ops in the generated code, just cleanup of type issues and removal of some implementation-defined behavior. the one exception is the change in the comparison value, which is fixed so that 0xf...f000 (which in principle could be a valid return value for mmap, although probably never in reality) is not treated as an error return.
2011-09-23FD_ISSET must return an int. this is the easiest way.Rich Felker-1/+1
casting to int would not be correct because high bits could be lost. mapping the high bits down onto low bits would be costlier in the common case where the result is just used in a conditional. changing the type of the bit array elements to int would permute the order of the bit array on 64-bit big endian systems, so that's not an option either.
2011-09-23sys/user.h may need stdint.hRich Felker-0/+1
2011-09-20fix some header typosRich Felker-1/+1
2011-09-20fix the fsid_t structure to match name of __valRich Felker-1/+1
this is a case of poorly written man pages not matching the actual implementation, and why i hate implementing nonstandard interfaces with no actual documentation of how they're intended to work.
2011-09-19fix the definition of struct statvfs to match lsb abiRich Felker-7/+24
at the same time, make struct statfs match the traditional definition and make it more useful, especially the fsid_t stuff.
2011-09-19fix broken multi-inclusion guard in sys/reg.hRich Felker-2/+2
2011-09-18cleanup more bits cruft (sysmacros and socket)Rich Felker-1/+199
2011-09-15implement ptrace syscall wrapper (untested)Rich Felker-1/+1
2011-08-27fix broken FD_* macros on 64-bit targetsRich Felker-3/+3
1 is too small if int is 32-bit but unsigned long is 64-bit. be explicit and use 1UL.
2011-07-09add missing signalfd flagsRich Felker-0/+3
2011-06-18copy-paste error in prctl.hRich Felker-1/+1
2011-06-16fix some struct padding to match LSB/glibc ABI where it may be helpfulRich Felker-2/+4
2011-05-08eventfd syscall wrapper and read/write wrappersRich Felker-0/+25
2011-04-21move wait.h macros out of bits. they do not vary.Rich Felker-2/+22
2011-04-21include signal.h to avoid thorny __sigcontext/sigcontext issuesRich Felker-2/+2
this is explicitly allowed by POSIX
2011-04-14add useless type fd_mask. it's in the reserved namespace.Rich Felker-0/+2
2011-04-13numerous fixes to sysv ipcRich Felker-13/+55
some of these definitions were just plain wrong, others based on outdated ancient "non-64" versions of the kernel interface. as much as possible has now been moved out of bits/* these changes break abi (the old abi for these functions was wrong), but since they were not working anyway it can hardly matter.
2011-04-13fix typos on RLIM_NLIMITS, remove _GNU_SOURCE test for itRich Felker-3/+1
RLIM_* is in the reserved namespace for this header
2011-04-13fix and cleanup suseconds_t/timeval stuff (broken on 64-bit)Rich Felker-9/+1
trash in the upper 32 bits was making the kernel sleep forever in select on 64-bit systems.
2011-04-12add some traditional aliases to stat.hRich Felker-0/+6
2011-04-12add missing rlimit macrosRich Felker-0/+8
2011-04-11cleanup types stuff in headers, fix missing u_int*_t in sys/types.hRich Felker-7/+9
2011-04-10add some ugly legacy type names in sys/types.h (u_char etc.)Rich Felker-0/+8
2011-04-10add legacy BSD-style timer*() macros in sys/time.hRich Felker-0/+10
2011-04-10add missing UTIME_* macros in sys/stat.hRich Felker-0/+3
2011-04-06fix typo in sys/msg.hRich Felker-1/+1
2011-04-06fix incorrect (and conflicting on LP64 archs) types for sysv ipc msgq functionsRich Felker-1/+1
2011-04-05alternate name for syslog.hRich Felker-0/+1
2011-03-19syscall overhaul part two - unify public and internal syscall interfaceRich Felker-1/+17
with this patch, the syscallN() functions are no longer needed; a variadic syscall() macro allows syscalls with anywhere from 0 to 6 arguments to be made with a single macro name. also, manually casting each non-integer argument with (long) is no longer necessary; the casts are hidden in the macros. some source files which depended on being able to define the old macro SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall() instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL have also been changed. x86_64 has not been tested, and may need a follow-up commit to fix any minor bugs/oversights.
2011-03-19add some ioctl stuff to sys/mount.hRich Felker-0/+18
2011-03-19overhaul syscall interfaceRich Felker-0/+16
this commit shuffles around the location of syscall definitions so that we can make a syscall() library function with both SYS_* and __NR_* style syscall names available to user applications, provides the syscall() library function, and optimizes the code that performs the actual inline syscalls in the library itself. previously on i386 when built as PIC (shared library), syscalls were incurring bus lock (lock prefix) overhead at entry and exit, due to the way the ebx register was being loaded (xchg instruction with a memory operand). now the xchg takes place between two registers. further cleanup to arch/$(ARCH)/syscall.h is planned.
2011-03-18various legacy and linux-specific stuffRich Felker-0/+107
this commit is part of an effort to make more of busybox work out-of-the-box.
2011-03-14remove some old cruft from sys/types.hRich Felker-1/+0
2011-03-08fcntl.h should make availabel the mode constants from sys/stat.hRich Felker-8/+2
also remove some legacy nonsense that crept in.
2011-03-03namespace cleanup in sys/mman.hRich Felker-1/+3
2011-02-27implement futimens and utimensatRich Felker-0/+3
2011-02-27cleanup namespace in sys/time.hRich Felker-4/+5
2011-02-20include sys/sysmacros.h from sys/types.h when _GNU_SOURCE is definedRich Felker-0/+1
2011-02-20fix typo in inotify structureRich Felker-1/+1
2011-02-20make sys/param.h not depend on PATH_MAX and NAME_MAXRich Felker-2/+2
this is a nonstandard header used only by backwards programs, but for some reason it's extremely popular. the recent namespace cleanup fixes broke it, because PATH_MAX and NAME_MAX will not be defined unless an approriate feature test macro has been defined. moreover, it's too late to just #define _GNU_SOURCE in param.h, since limits.h may have already been included. let's just hard-code standard values and be done with it.
