2012-09-08syscall organization overhaulRich Felker1-18/+0
now public syscall.h only exposes __NR_* and SYS_* constants and the variadic syscall function. no macros or inline functions, no __syscall_ret or other internal details, no 16-/32-bit legacy syscall renaming, etc. this logic has all been moved to src/internal/syscall.h with the arch-specific parts in arch/$(ARCH)/syscall_arch.h, and the amount of arch-specific stuff has been reduced to a minimum. changes still need to be reviewed/double-checked. minimal testing on i386 and mips has already been performed.

2012-09-07default features: make musl usable without feature test macrosRich Felker14-15/+24
the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker5-13/+43
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2012-09-02avoid "inline" in public headers for strict c89 compatibilityRich Felker1-0/+4
while musl itself requires a c99 compiler, some applications insist on being compiled with c89 compilers, and use of "inline" in the headers was breaking them. much of this had been avoided already by just skipping the inline keyword in pre-c99 compilers or modes, but this new unified solution is cleaner and may/should result in better code generation in the default gcc configuration.
2012-08-24type exposure fixes in sys/sem.hRich Felker1-2/+5
2012-08-15add missing xattr functionsRich Felker1-0/+3
not sure why these were originally omitted..
2012-08-05fix socket.h on mipsRich Felker1-0/+3
why does mips have to be gratuitously incompatible in every possible imaginable way?
2012-07-23add ioperm/iopl syscallsRich Felker1-0/+13
based on patches by orc and Isaac Dunham, with some fixes. sys/io.h exists and contains prototypes for these functions regardless of whether the target arch has them; this is a bit unorthodox but I don't think it will break anything. the function definitions do not exist unless the appropriate SYS_* syscall number macro is defined, which should make sure configure scripts looking for these functions don't find them on other systems. presently, sys/io.h does not have the inb/outb/etc. port io macros/functions. I'd be surprised if ioperm/iopl are useful without them, so they probably need to be added at some point in appropriate bits/io.h files...
2012-07-23add extended attributes syscallsRich Felker1-0/+27
based on patch by orc and Isaac Dunham, with some fixes.
2012-07-12workaround another sendmsg kernel bug on 64-bit machinesRich Felker1-7/+0
the kernel wrongly expects the cmsg length field to be size_t instead of socklen_t. in order to work around the issue, we have to impose a length limit and copy to a local buffer. the length limit should be more than sufficient for any real-world use; these headers are only used for passing file descriptors and permissions between processes over unix sockets.
2012-06-23add process_vm_readv and process_vm_writev syscall wrappersRich Felker1-0/+9
based on a patch submitted by Kristian L. <email@thexception.net>
2012-06-15header file fixes: multiple include guard consistency and correctnessRich Felker3-6/+6
one file was reusing another file's macro name, and many had inconsistent underscores and application of SYS prefix, etc. patch by Szabolcs Nagy (nsz)
2012-06-07fix sysinfo, try 2. it seems to work this time.Rich Felker1-10/+10
2012-06-07sysinfo struct was utter nonsense; no idea where it came from.Rich Felker1-4/+3
this broke the busybox "free" utility (memory reporting) and possibly other things like uptime.
2012-06-04_GNU_SOURCE is supposed to imply _LARGEFILE64_SOURCERich Felker7-7/+7
this is ugly and stupid, but now that the *64 symbol names exist, a lot of broken GNU software detects them in configure, then either breaks during build due to missing off64_t definition, or attempts to compile without function declarations/prototypes. "fixing" it here is easier than telling everyone to add yet another feature test macro to their builds.
2012-05-22various header cleanups, some related to _BSD_SOURCE additionRich Felker1-4/+4
there is no reason to avoid multiple identical macro definitions; this is perfectly legal C, and even with the maximal warning options enabled, gcc does not issue any warning for it.
2012-05-22support _BSD_SOURCE feature test macroRich Felker5-5/+9
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
2012-05-10fix missing parens in bit op macros (param.h)Rich Felker1-1/+1
2012-05-10and another bug in setbit, etc. macros..Rich Felker1-1/+1
2012-05-10fix typo in sys/param.h that broke setbit, etc. macrosRich Felker1-1/+1
this is all junk, but some programs use it.
2012-05-04add *64 junk for sys/*.h headersRich Felker7-0/+50
2012-04-18legacy junk compatibility grab-bagRich Felker1-7/+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
2012-02-07fix typo in inotify.hRich Felker1-1/+1
2012-02-01apparently gnu caddr_t is supposed to be char *, not unsigned longRich Felker1-1/+1
this type should never be used anyway, but some old junk uses it..
2012-01-28add linux setfs[ug]id syscall wrappersRich Felker1-0/+20
patch by Jeremy Huntwork
2012-01-26remove useless "extern" keywords in headersRich Felker1-1/+1
2012-01-24add MIN/MAX macros to sys/param.hRich Felker1-0/+5
this is a nonstandard junk header anyway, so just do what apps expect..
2012-01-24add legacy futimes and lutimes functionsRich Felker1-0/+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 Felker1-0/+8
2011-11-10fix all missing instances of __cplusplus checks/extern "C" in headersRich Felker12-0/+95
patch by Arvid Picciani (aep)
2011-10-17fix some details in ugly stuff that doesn't belong in libcRich Felker1-0/+2
patches by sh4rm4, presumably needed to make gdb or some similar junk happy...
2011-09-26cleanup various minor issues reported by nszRich Felker1-1/+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 Felker1-1/+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 Felker1-0/+1
2011-09-20fix some header typosRich Felker1-1/+1
2011-09-20fix the fsid_t structure to match name of __valRich Felker1-1/+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 Felker2-7/+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 Felker1-2/+2
2011-09-18cleanup more bits cruft (sysmacros and socket)Rich Felker2-1/+199
