2024-08-11add memfd_create syscall wrapperWaldemar Brodkorb
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..

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.

2017-10-11h8300: remove dead codeWaldemar Brodkorb
As h8/300 architecture does not use deprecated syscalls after reintroduction into Linux upstream, this part of the code in vfork.S is always unused.

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>

2012-10-02libc/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.

2009-07-26enable 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.

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.
