2021-04-09open: Add support for O_TMPFILENicolas Cavallari
Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY) to make it fail on old kernels. Copying definitions from glibc for O_TMPFILE is not enough to support O_TMPFILE; The open() wrapper also need to pass the mode when the flag contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed but yield unexpected results. openat() is curiously not affected since it passes the mode unconditionally..

2021-02-19fcntl.h: Make F_DUPFD_CLOEXEC if _USE_XOPEN2K8Paul Cercueil
The F_DUPFD_CLOEXEC flag was added in POSIX 2008.09. Signed-off-by: Paul Cercueil <paul@crapouillou.net>
2020-07-02Rename __unused struct members to include a namespaceEd Wildgoose
Rename various spare fields in structs to include a namespace This should avoid accidental clashes with uses of the __unused symbol in upstream projects. eg currently it causes a compile error in dhcpcd 8.x due to their re-use of the __unused symbol as a macro This follows the style of glibc which does something equivalent
2020-02-03csky: add statx conditionalsWaldemar Brodkorb
Similar to glibc commit https://sourceware.org/git/?p=glibc.git;a=commit;h=6bbfc5c09fc5b5e3d4a0cddbbd4e2e457767dae7 we need to handle Linux kernel change, which removed stat64 family from default syscall set.

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.
2018-01-15nds32: 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>
2017-06-08fcntl.h: fixup namespace for O_DIRECTORY/O_NOFOLLOW/O_CLOEXECWaldemar Brodkorb
Sync with GNU C library. Found while trying to compile linux-rdma to uClibc-ng. Reported-by: Alexey Brodkin <Alexey.Brodkin@synopsys.com>
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>
2016-12-02nds32: in latest gcc from Andes, this got renamedWaldemar Brodkorb
2016-06-30nds32: add support for new architectureWaldemar Brodkorb
Add support for Andes Technology NDS32 architecture. See here http://www.andestech.com/en/index/index.htm for more informaton. Verification of the port from an older uClibc port was done on a sponsored AG101p board. The testsuite only has 5 errors, three are related to an existing bug in dlclose() with LT.old, also happening on cris32 and m68k. Failures to fallocate/posix_fallocate are unresolved. Thanks to Andes Technology sponsoring the hardware and being very helpful while doing the uClibc-ng porting. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>
