2012-04-18legacy junk compatibility grab-bagRich Felker-0/+1
- 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
2012-03-16remove junk sincos implementations in preparation to merge nsz's real onesRich Felker-24/+0
2012-03-15implement sincosf and sincosl functions; add prototypesRich Felker-0/+16
presumably broken gcc may generate calls to these, and it's said that ffmpeg makes use of sincosf.
2012-01-28add linux setfs[ug]id syscall wrappersRich Felker-0/+16
patch by Jeremy Huntwork
2011-12-23fix broken reboot wrapper (syscall needs extra silly magic arguments...)Rich Felker-1/+1
2011-09-28make getmntent_r discard long lines when it returns error, not seek backRich Felker-2/+1
seeking back can be performed by the caller, but if the caller doesn't expect it, it will result in an infinite loop of failures.
2011-09-27improve error handling in mntent stuff...Rich Felker-2/+9
not sure if this is correct/ideal. it needs further attention.
2011-09-27fix missing va_end in prctl syscall wrapperRich Felker-0/+1
2011-09-26cleanup various minor issues reported by nszRich Felker-2/+2
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.
2011-08-02fix stubbed-out reboot callRich Felker-3/+2
2011-05-22fix brk/sbrk behavior to match the real legacy functionsRich Felker-2/+4
2011-05-08eventfd syscall wrapper and read/write wrappersRich Felker-0/+21
2011-04-20fix initgroups (uninitialized count passed to getgrouplist)Rich Felker-1/+1
2011-04-13add syscall wrapper for flockRich Felker-0/+7
it should be noted that flock does not mix well with standard fcntl locking, but nonetheless some applications will attempt to use flock instead of fcntl if both exist. options to configure or small patches may be needed. debian maintainers have plenty of experience with this unfortunate situation...
2011-04-13fix bug whereby getopt_long allowed mismatch in last char of option nameRich Felker-1/+1
2011-04-13fix prototypes/signature for setgroups, etc.Rich Felker-1/+1
2011-04-06fix completely bogus loop condition in getmntent_rRich Felker-1/+1
somehow this worked on my simple fstab, but horribly broke in general, leading to use of uninitialized offset array and crashes.
2011-04-05implement the adjtime and adjtimex functions (nonstandard)Rich Felker-0/+34
2011-04-05add getmntent_r interface (all of mntent is nonstandard anyway)Rich Felker-12/+17
2011-04-05add pivot_root syscall wrapperRich Felker-0/+6
2011-04-05support the nonstandard err.h interfacesRich Felker-0/+60
note that unlike the originals, these do not print the program name/argv[0] because we have not saved it anywhere. this could be changed in __libc_start_main if desired.
2011-03-20global cleanup to use the new syscall interfaceRich Felker-32/+27
2011-03-19overhaul syscall interfaceRich Felker-0/+19
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.
2011-03-01depends on settimeofday which needs _GNU_SOURCE feature testRich Felker-0/+1
2011-02-19workaround gcc bug 46926 by providing a dumb sincos implementationRich Felker-0/+8
note that this library itself is built with -ffreestanding so sincos.c should not be miscompiled even if the gcc used to compile musl has this bug.
2011-02-19add syscall wrappers for inotifyRich Felker-0/+28
2011-02-19cleanup cruft left from when kernel and user time_t disagreedRich Felker-12/+3
2011-02-17make daemon try the operations that might fail before fork rather than afterRich Felker-12/+10
2011-02-17daemon should check for failures and return -1Rich Felker-5/+8
2011-02-15remove standalone syscall cruftRich Felker-10/+0
this was originally written for an early draft of the library where non-standard functions would reside in a static library separate from the shared libc.so, which would implement a pure standard. the idea was not to depend on an implementation-dependent __syscall_ret function in the main libc. but it turned out to be better to put everything in a single library for both static and dynamic linking uses, and thus the (incomplete) remnants of this feature were just enlarging the source and binary.
2011-02-13cleaning up syscalls in preparation for x86_64 portRich Felker-3/+1
- hide all the legacy xxxxxx32 name cruft in syscall.h so the actual source files can be clean and uniform across all archs. - cleanup llseek/lseek and mmap2/mmap handling for 32/64 bit systems - alternate implementation for nice if the target lacks nice syscall
2011-02-13syscall cleanup for umount2Rich Felker-1/+0
2011-02-13use umount2 syscall for umount (new targets lack old 1-arg umount)Rich Felker-2/+1
