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>

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.

2017-03-20remove RPC implementationWaldemar Brodkorb
The included RPC implementation is ipv4 only. Other C library projects have either deprecated the internal RPC implementation (GNU C Library) or never implemented such functionality (musl C Library). The latest rpcbind release (0.2.4) checks for libtirpc and does not allow to be build with uClibc-ng RPC without patching. The common use case for RPC nowadays is to use rpcbind together with nfs-utils to provide NFS server or client support to a system. The included RPC implementation does create issues with duplicate symbol failures when statically compiling with RPC enabled.
