2018-01-06ld.so: Rewrite elf_machine_load_address using _DYNAMIC symbolWaldemar Brodkorb
Sync with GNU C library commit: commit a68ba2f3cd3cbe32c1f31e13c20ed13487727b32 Author: Szabolcs Nagy <szabolcs.nagy@arm.com> Date: Wed Oct 18 17:26:23 2017 +0100 Fixes issues with binutils version > 2.29.1.
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.

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.

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.

2017-09-14arc: Ensure that debugger can recognize sigrestorerAnton Kolesov
An issue has been found with current implementation of signal restorer function in uClibc and how GDB handles it. When debugger information is not present, everything worked fine, because GDB would use a built-in logic to determine if function is a signal restorer. However when debugging information is present, debugger would rely solely on it and wouldn't use ARC-specific functions to detect signal handler frames. Because debug information for signal restorer is generated completely by the compiler, it lacks a marker, that identifies this as a signal frame that requires special handling. While it is possible to insert that marker via inline assembly, that still doesn't solve the whole problem, because some other expectations are not met by the debug information - there is no "nop" in front of the function, needed to fool debugger into thinking that this was a function call, and references to previous frame information need to be described manually. The simplest way to fix the problem is just to make sure that signal restorer function will not have any debug function at all, which can be done by writing it in assembly. Alternative, more complex, solution, where debug information for signal frame is manually defined can be found in glibc/sysdeps/unix/sysv/linux/x86_64/sigaction.c [1].

2017-08-20arc: Merge ARCv2 string routines in generic ARC .S filesAlexey Brodkin
In cde74b83f9b2 "ARC: remove special CFLAGS/LDFLAGS handling" we got rid of CONFIG_ARC_CPU_HS which was used to select ARCv2-specific implementation of optimized string routines. So now ARCv2-tuned memset/memcpy/strcmp are not used, instead those for ARC700 used for both ARC700 and ARCHS. Without uClibc config option we may only tell which CPU type we're targeting by built-in defines of GCC. I.e. no more conditional file inclusion in Makefiles. That leaves us only one option - merge both implementations in 1 file and use ifdefs. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
