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.
2017-12-03x86_64: add fenv support from glibcWaldemar Brodkorb
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>
2015-12-07add definitions for O_PATHWaldemar Brodkorb
Only alpha, hppa and sparc need non-default value.
2015-12-05remove __UCLIBC_ASM_GLOBAL_DIRECTIVE__Waldemar Brodkorb
.globl can be used for every architecture so remove the define. Sync with GNU C library.
2015-12-05remove __UCLIBC_HAVE_ASM_GLOBAL_DOT_NAME__Waldemar Brodkorb
It's even no longer required for non-ported ppc64 architecture. Sync with GNU C library. This simplify the macros in include/libc-symbols.h.

2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger
The reason truncate64 takes 4 args on some arches is that their ABI requires 64bit values to be aligned on register pair boundaries. Since this alignment affects more than just truncate64, rename the define to properly document its purpose. This also allows us to expand it to the other impacted syscalls (which will be done in a follow up commit). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-11-18drop support for pre ISO-C compilersMike Frysinger
This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless. Really, the point of this is to stay in sync with what glibc did. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-10-02libc/sysdeps: add __kernel_long and __kernel_ulongChris Packham
Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various exported header files were updated to use these new types. Add the definitions for __kernel_long_t and __kernel_ulong_t to the relevant kernel_types.h headers. This change was automated with the following scriptlet git grep --name-only 'typedef.*__kernel_old_dev_t' \ | xargs sed -i '/typedef.*__kernel_old_dev_t/ a\ typedef long\t\t__kernel_long_t;\ typedef unsigned long\t__kernel_ulong_t;' Whitespace in arm, avr32, hppa, sparc was then manually fixed up. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> -- Here's a cleaned up patch which should get the whitespace right. I'm a bit iffy about the sparc changes they make sense to me but it's not a platform I have access to.

2009-11-23bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger
Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-26enable nanosecond stat support for everyoneMike Frysinger
Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes.

2009-07-21byteswap: unify common definitionsMike Frysinger
The majority of the byteswap functions are the same across all arches, so setup a common header to provide definitions if they don't exist. This allows arches to override only the ones they actually want to implement with inline assembly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-08syscall: unify common syscall definesMike Frysinger
Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports.

2008-01-17A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt
a problem where the linker was trying to use the wrong symbol name for the init function. Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960, microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets which define SYMBOL_PREFIX as _. Remove defines and undefs from uClibc_arch_features.h of each target. Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.
