2018-06-10risc-v: initial 64 bit port, static only (no TLS/NPTL)Waldemar Brodkorb
Only a simple hello world is tested in qemu system emulation.
2018-04-17common/sendfile.c: bugfix can't support offset is NULLGuo Ren
In ltp testcase sendfile08.c, it use offset=NULL to test the api. PATCH V2: fixup the stupid missing check in the end. Sorry for lose test. See "man sendfile" and it really support offset is NULL. Signed-off-by: Guo Ren <ren_guo@c-sky.com>
2018-04-17Revert "common/sendfile.c: bugfix can't support offset is NULL"Waldemar Brodkorb
This reverts commit b00fd230ed0b49b9f23d829ad5d09859f34bb754.

2018-04-02use __NR_newfstatat only for modern Linux architecturesWaldemar Brodkorb
Otherwise it breaks mips64 n64. Should be used for aarch64/tilegx only.
2018-03-12tile: add basic support for tilegxWaldemar Brodkorb
This adds basic support for tile architecture. Only static binaries, no ld.so or threading support. Tested with qemu-tilegx only.
2018-02-17bits/socket.h: add missing definesWaldemar Brodkorb
Newer iproute2 package make use of some of defines. Sync missing defines with GNU C library.
2018-02-04mman: disable memfd_create declarationWaldemar Brodkorb
2018-02-03bits/mman.h: consolidate header fileWaldemar Brodkorb
Sync with GNU C library and consolidate duplicate non architecture specific defines. MAP_UNINITIALIZED is only defined to 0x4000000 and used by the Linux kernel when CONFIG_MMAP_ALLOW_UNINITIALIZED is enabled. CONFIG_MMAP_ALLOW_UNINITIALIZED is only available for nommu. See Documentation/nommu-mmap.txt.
2018-01-21simplify and fix getcwdWaldemar Brodkorb
The fallback code is not used as all supported kernels have the syscall. Check if a absolute path is returned from syscall.
2018-01-15rt: cleanup and allow to build for linuxthreadsWaldemar Brodkorb
It seems there is no real dependency to NPTL for these clock_* functions when UCLIBC_ADVANCED_REALTIME is enabled. No regressions found. Reported-by: Baruch Siach <baruch@tkos.co.il>
2018-01-15syscall: Make common implementation match unistd.hStafford Horne
The definition of syscall() in unistd.h is with varargs. Traditionally the common implementation in uclibc has been with regular arguments. This patch updates that by using varargs. This has caused issues on architectures like or1k which have different calling conventions for varargs and regular arg parameters. The implementation here is based on an implementation from Joel Stanley <joel@jms.id.au>. There is a difference that I do not initialize the stack args with 0 as they are immediately overwritten by va_args. Signed-off-by: Stafford Horne <shorne@gmail.com>
2018-01-08csky: bugfix libc sync_file_range.c for csky.Guo Ren
Use __NR_sync_file_range2 for csky sync_file_range function. Signed-off-by: Guo Ren <ren_guo@c-sky.com>
2017-12-31m68k: add NPTL/TLS supportWaldemar Brodkorb
Port over NPTL/TLS support from GNU C Library. In the first step only the slower syscall is used for TLS access. The uClibc-ng testsuite shows 79 errors, so their is room for bugfixes and improvements.
2017-11-25statfs.h: add f_flagsWaldemar Brodkorb
Add missing member in struct statfs. It is used by xfsprogs (f.e. 4.13.1). Reported-by: Joshua Kinard <kumba@gentoo.org>
2017-11-22librt: fix broken posix_spawnWaldemar Brodkorb
Fix iteration over signals, synced with GNU C library code and pending patches. Issues found when running dhcpcd with hook scripts. (exit status 127) Reported-By: kapeka <kapeka@bering-uclibc.de>
2017-11-19csky: port to uclibc-ngGuo Ren
Follow the steps to build c-sky uclibc linux system: 1. git clone https://github.com/c-sky/buildroot.git 2. cd buildroot 3. make qemu_csky_ck810_uclibc_defconfig 4. make Follow the buildroot/board/qemu/csky/readme.txt to run. This buildroot toolchain is pre-build, But you can rebuild the c-sky uclibc-ng alone and install it to the buildroot sysroot manually. We'll try our best to improve the uclibc-ng continuously.

2017-11-19remove unused FORTIFY code fragmentsWaldemar Brodkorb
2017-11-03math: add exception handling functionalitySergey Cherkashin
According to standards SVID and SYSV. Modified lgamma calling in case when 'signgam' variable should not be used. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>
2017-10-01preadv/pwritev: bugfix preadv/pwritev syscall should be 5 argsGuo Ren
The current uclibc-ng use 4 arguments, and this will cause ltp-testsuite's preadv/pwritev case failed. The syscall of preadv/pwritev in current linux-kernel is 5 arguments: linux/fs/read_write.c: SYSCALL_DEFINE5(preadv, unsigned long, fd, const struct iovec __user *, vec, unsigned long, vlen, unsigned long, pos_l, unsigned long, pos_h) SYSCALL_DEFINE5(pwritev, unsigned long, fd, const struct iovec __user *, vec, unsigned long, vlen, unsigned long, pos_l, unsigned long, pos_h) So just update to 5-args-syscall, and off_t could be 32bit or 64bit. Signed-off-by: Guo Ren <ren_guo@c-sky.com>
2017-08-10sys/ptrace.h: remove obsolete Linux PTRACE_SEIZE_DEVEL constantWaldemar Brodkorb
Remove enum __ptrace_flags along with the only constant it contains, PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files. Following GNU C library commit: 60e2846e2633a990bdf474004a373bde54c0bc5f
2017-07-28fix tolower and localesEugene Yudin
The function towlower doesn't work with locales different from C. Issue was introduced in commit: 8cde3a9bf2856dcb9a759dec7ecb04a68e712254 Call to setlocale is needed for correct generation of the table uplow_diff. Otherwise you receive compile time error "range assumption error" after uncommenting the call. Similar problem described here: http://lists.uclibc.org/pipermail/uclibc/2015-March/048852.html This commit fix the problem by using int32_t values.
2017-06-23sparc64: add basic supportWaldemar Brodkorb
No NPTL, no LDSO support. Bootup with Busybox Ash in Qemu working. Testuite shows only two failures, but mksh continue/break support doesn't work.
2017-06-21remove editor hints for viWaldemar Brodkorb
2017-04-22remove unused HP_TIMING_AVAIL and headerWaldemar Brodkorb
cleanup unused and unsupported code.
2017-04-16libm: allow long double wrappers for all architecturesWaldemar Brodkorb
If you enable these wrappers, be sure you don't need long double precision on your embedded device, as these only enables long double warpper functions to the existing double math functions. Required to build some software as lvm2. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2017-02-03fstat: make new code aarch64 specificWaldemar Brodkorb
The new code get's used by MIPS64 N64 and fails. Make the new code aarch64 specific.
2017-02-01add experimental aarch64 supportWaldemar Brodkorb
Ported over from GNU C Library and runtime tested in Qemu.
2017-01-28remove PID cachingWaldemar Brodkorb
Follow GNU C Library from c579f48edba88380635ab98cb612030e3ed8691e and remove the PID caching. These simplifies the architecture specific assembly code. The run of the test suite found no regressions, it even solves some of the test failures for x86/x86_64/sparc.

2017-01-22nds32: add NPTL/TLS, *context function, libm changes and code cleanupVincent Ren-Wei Chen
This commit includes following features. 1. Support NPTL/TLS 2. Add libm function which is used to handle FP rounding and excpetions (ex: fclrexcpt,fedisblxcpti,feenablxcpt... ) 3. Add *context function for operating user context (ex: setcontext,getcontext,makecontext... ) 4. Change the return flow from signal handler 5. Cleanup of old code The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1, which are related to timing accuracy. (math and locale tests are disabled) Signed-off-by: Vincent Ren-Wei Chen <vincentc@andestech.com>

2016-12-28add init_module/delete_module syscall wrappersWaldemar Brodkorb
Add the wrappers unconditionally, because kmod package still uses them.
2016-12-23remove UCLIBC_LINUX_MODULE_26Waldemar Brodkorb
The syscall wrappers are not required and other C libraries do not provide them. Busybox modutils.c must be patched so that syscall() is used for uClibc-ng. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org>

2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance
2016-09-26always assume tgkill is presentWaldemar Brodkorb

2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT.
