2017-04-22sys/stat.h: fix missing struct timespec definitionDamien Riegel
This is a second attempt to fix a compilation failure involving a missing struct timespec definition in some situation. Previous attempt was following commit but it had undesirable side effects and was reverted: 657c4a9d6c fcntl.h: fix a missing `struct timespec` definition A similar issue was identified and reported in glibc [1], and the fix was to include the timespec definition if __USE_XOPEN2K8 was defined. To minimize the possible impact of this new fix, it was decided to not replace __USE_ATFILE by __USE_XOPEN2K8 as glibc did, but to add an additional OR condition on __USE_XOPEN2K8.

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>
2017-04-08Same iteration variable used for inner and outer loopCupertino Miranda
Inner loop was using same counter variable (i) as the outer loop, therefore making outer loop terminate before it visited all of the ELF program segments. Surrounding code in this inner loop clearly shows the intention that this loop should not affect the outer one, therefore leading me to the conclusion that this should be a bug an not expected code. This bug was detected due to some other bug in ARC binutils that kept setting TEXTREL for any PIE application. Apart from the but, I have also moved the debug message inside of the TEXTREL condition as mprotect is only really called if TELTREL is set.
2017-04-08ldso: exit if zalloc can't alloc memoryVineet Gupta
_dl_zalloc callers don't check for allocaton failure. It kind of makes sense since such early allocations are unlikely to fail, and even if they do, ldso would segv anyways thus bringing the issue to attention. However there's a gcc nuance which led to this patch. It seems gcc at -O2 (for DODEBUG build), does additional coge gen analysis for pointer dereference from erroneous paths and it "isolates" such code paths with a intrinsic abort/trap etc. The ldso code fragment which was triggering this: | add_ldso(struct dyn_elf *rpnt) | if (rpnt) | ... | else | rpnt = _dl_zalloc() | | rpnt->dyn = tpnt <---- potential NULL pointer deref ARC gcc currently generates an abort() call which doesn't exist in ldso, causing link errors (with a newer vrsion of binutils). ARM gcc 6.2.1 behaves similarly, altough instead of abort, it generates a trap inducing UDF instruction | 367c: ebfffb79 bl 2468 <_dl_malloc> | 3680: e51b2068 ldr r2, [fp, #-104] ; 0xffffff98 | 3684: e3500000 cmp r0, #0 | 3688: 0a000006 beq 36a8 <_dl_add_elf_hash_table+0x280> | ... | 36a8: e5862000 str r2, [r6] | 36ac: e7f000f0 udf # So add an explict dl_exit() in dl_zalloc error case to beat the compiler. Note that this error propagagtion analysis stops if the function in consideration (_dl_zalloc) is NOT inlined. Hence the reason it only shows up for DODEBUG builds which builds ldso at -O2 which is more aggressive about inlining. If this patch is not considered worth applying then the workaround suggested by Claudiu is to to build ldso with -fno-isolate-erroneous-paths-dereference Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Either toolchain defaults or buildsystems should provide the architecture specific CFLAGS and LDFLAGS.
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.

2017-02-28fcntl.h: fix a missing `struct timespec` definitionDamien Riegel
If a source file is compiled with: #define _XOPEN_SOURCE 700 #define _POSIX_C_SOURCE 200112L Then including fcntl.h results in the following error: In file included from fcntl.h:37:0, from test.c:4: sys/stat.h:371:54: error: array type has incomplete element type ‘struct timespec’ extern int futimens (int __fd, const struct timespec __times[2]) __THROW; To fix that, we force the definition of struct timespec in fcntl.h when __USE_XOPEN2K8 is defined. This mimics the behavior of glibc which contains the following line in its io/fcntl.h header (included by fcntlh.h): #ifdef __USE_XOPEN2K8 # include <bits/types/struct_timespec.h> #endif This bug was spotted during the compilation of BoringSSL against uClibc.

As reported by Buildroot developers these files causing static linking issues. The original contribution with the ARM unwind-resume rework and GNU libc sync was made before the combined libc change.
