2018-01-15nptl: use generic lowlevellock.h for most architecturesWaldemar Brodkorb
Only mips/x86/x86_64 needs a special version of lowlevellock.h. No regressions found.
2018-01-15nds32: Add syscall macros for 5 and 6 parametersStafford Horne
This is to fix an error after switching to use generic syscalls. libc/sysdeps/linux/common/syscall.c: In function 'syscall': libc/sysdeps/linux/common/syscall.c:27:2: warning: implicit declaration of function 'internal_syscall_ncs6' [-Wimplicit-function-declaration] return INLINE_SYSCALL_NCS(sysnum, 6, arg1, arg2, arg3, arg4, arg5, arg6); ^ Defining these functions as described by Vincent Ren-Wei Chen <vincentc@andestech.com> Signed-off-by: Stafford Horne <shorne@gmail.com>
2018-01-15nds32: Use new common syscall() implementationStafford Horne
Traditionally nds32 has had a generic syscall implementation supporting varargs. During an audit it was found that this implementation seems to duplicate the new common implementation and is no longer needed. Signed-off-by: Stafford Horne <shorne@gmail.com>
2018-01-15or1k: Use new common syscall() implementationStafford Horne
Now that the common syscall implementation supports vararg calling conventions we can safely use it on OpenRISC. This saves a bit of code in the openrisc implementation. Signed-off-by: Stafford Horne <shorne@gmail.com>
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>

2018-01-03fdpic: fix ld.so crashingWaldemar Brodkorb
Newer binutils is creating a section INIT_ARRAY from any .init_array and .ctors in the code. When ld.so runs initialization functions for loaded objects with _dl_run_init_array() it crashes on Bfin FDPIC system. It is trying to execute the function in pthread.c, which is no longer useful with the combined C library approach. Gcc -Wl,-M debugging output was very useful to find the reason for the INIT_ARRAY section.

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.

2017-12-10or1k: syscall: Pass arguments on the stackJoel Stanley
Busybox internally calls syscall(2). - in unistd.h defined something like int syscall(nr, ....) - in syscall.c (common) implemented as int syscall(nr, arg1, arg3, arg3, arg4, arg5, arg6) This will not work, busybox thinks syscall should have varargs calling conventions. But it doesnt in the uclibc implementation so no args go through. Most architectures this will work. But on openrisc varargs are all sent on the stack. Regular args are passed in registers.

2017-11-28Fix build regression with DO_XSI_MATH disabledRonald Wahl
Commit ea38f4d89 (math: add exception handling functionality) adds a regression so that build configurations that have DO_C99_MATH enabled and DO_XSI_MATH disabled will not link. This commit moves the files with the bessel functions from DO_C99_MATH to DO_XSI_MATH. It looks like they are not even contained in C99. Signed-off-by: Ronald Wahl <ronald.wahl@raritan.com>

2017-11-22remove misleading comment about f_frsize fieldEugene Rudoy
It is supported both in the sense of being contained in mips version of statfs/statfs64 structs and also in the sense that it's filled by the corresponding kernel syscalls. It is UNsupported in that sense that it's value is the same as that of f_bsize (at least on older kernel versions, the oldest version tested is 2.6.13), s.

2017-10-01recvmmsg/sendmmsg: add recvmmsg sendmmsg support.Guo Ren
The recvmmsg and sendmmsg is very important for UDP stream application. If we only use recvmsg for UDP stream, it will only copy one mtu size of data in a syscall. And recvmmsg copy as many as you want in a syscall. So recvmmsg is more efficient,and some applications will depends on the recvmmsg and sendmmsg, eg: UDP media stream player.

2017-10-01statfs: bugfix statfs02 fstatfs02 failed in ltp-testsuiteGuo Ren
In the test-case of statfs from ltp-testsuite, it pass -1 to 2th argument. eg: fstatfs(fd , -1) When uclibc-ng parse the buf32 to buf will cause illegal address access, the kernel will signal the process with SIGSEGV. If we pass the -1 directly to the syscall of statfs/fstatfs, kernel use copy_to_user() to prevent the signal of SIGSEGV and just return EINVAL. This is the ltp-testsuite expect.

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.
