* legacy junk compatibility grab-bagRich Felker2012-04-181-7/+22
| | | | | | - add the rest of the junk traditionally in sys/param.h - add prototypes for some nonstandard functions - add _GNU_SOURCE to their source files so the compiler can check proto
* fix typo in inotify.hRich Felker2012-02-071-1/+1
|
* apparently gnu caddr_t is supposed to be char *, not unsigned longRich Felker2012-02-011-1/+1
| | | | this type should never be used anyway, but some old junk uses it..
* add linux setfs[ug]id syscall wrappersRich Felker2012-01-281-0/+20
| | | | patch by Jeremy Huntwork
* remove useless "extern" keywords in headersRich Felker2012-01-261-1/+1
|
* add MIN/MAX macros to sys/param.hRich Felker2012-01-241-0/+5
| | | | this is a nonstandard junk header anyway, so just do what apps expect..
* add legacy futimes and lutimes functionsRich Felker2012-01-241-0/+2
| | | | | based on patch by sh4rm4. these functions are deprecated; futimens and utimensat should be used instead in new programs.
* add prlimit syscall wrapperRich Felker2012-01-201-0/+8
|
* fix all missing instances of __cplusplus checks/extern "C" in headersRich Felker2011-11-1012-0/+95
| | | | patch by Arvid Picciani (aep)
* fix some details in ugly stuff that doesn't belong in libcRich Felker2011-10-171-0/+2
| | | | | patches by sh4rm4, presumably needed to make gdb or some similar junk happy...
* cleanup various minor issues reported by nszRich Felker2011-09-261-1/+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.
* FD_ISSET must return an int. this is the easiest way.Rich Felker2011-09-231-1/+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.
* sys/user.h may need stdint.hRich Felker2011-09-231-0/+1
|
* fix some header typosRich Felker2011-09-201-1/+1
|
* fix the fsid_t structure to match name of __valRich Felker2011-09-201-1/+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.
* fix the definition of struct statvfs to match lsb abiRich Felker2011-09-192-7/+24
| | | | | at the same time, make struct statfs match the traditional definition and make it more useful, especially the fsid_t stuff.
* fix broken multi-inclusion guard in sys/reg.hRich Felker2011-09-191-2/+2
|
* cleanup more bits cruft (sysmacros and socket)Rich Felker2011-09-182-1/+199
|
* implement ptrace syscall wrapper (untested)Rich Felker2011-09-151-1/+1
|
* fix broken FD_* macros on 64-bit targetsRich Felker2011-08-271-3/+3
| | | | | 1 is too small if int is 32-bit but unsigned long is 64-bit. be explicit and use 1UL.
* add missing signalfd flagsRich Felker2011-07-091-0/+3
|
* copy-paste error in prctl.hRich Felker2011-06-181-1/+1
|
* fix some struct padding to match LSB/glibc ABI where it may be helpfulRich Felker2011-06-161-2/+4
|
* eventfd syscall wrapper and read/write wrappersRich Felker2011-05-081-0/+25
|
* move wait.h macros out of bits. they do not vary.Rich Felker2011-04-211-2/+22
|
* include signal.h to avoid thorny __sigcontext/sigcontext issuesRich Felker2011-04-211-2/+2
| | | | this is explicitly allowed by POSIX
* add useless type fd_mask. it's in the reserved namespace.Rich Felker2011-04-141-0/+2
|
* numerous fixes to sysv ipcRich Felker2011-04-133-13/+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.
* fix typos on RLIM_NLIMITS, remove _GNU_SOURCE test for itRich Felker2011-04-131-3/+1
| | | | RLIM_* is in the reserved namespace for this header
* fix and cleanup suseconds_t/timeval stuff (broken on 64-bit)Rich Felker2011-04-132-9/+1
| | | | | trash in the upper 32 bits was making the kernel sleep forever in select on 64-bit systems.

* syscall overhaul part two - unify public and internal syscall interfaceRich Felker2011-03-191-1/+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.
* add some ioctl stuff to sys/mount.hRich Felker2011-03-191-0/+18
|
* overhaul syscall interfaceRich Felker2011-03-191-0/+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.
* various legacy and linux-specific stuffRich Felker2011-03-182-0/+107
| | | | | this commit is part of an effort to make more of busybox work out-of-the-box.
* remove some old cruft from sys/types.hRich Felker2011-03-141-1/+0
|
* fcntl.h should make availabel the mode constants from sys/stat.hRich Felker2011-03-081-8/+2
| | | | also remove some legacy nonsense that crept in.

|
* implement futimens and utimensatRich Felker2011-02-271-0/+3
|
* cleanup namespace in sys/time.hRich Felker2011-02-271-4/+5
