There's only two places where we're using the C99 feature of array
designated initalizers. This feature seemingly wasn't included with
C++20 designated initalizers for classes and structs. The only two
places we were using this feature are suitably old and isolated that
it makes sense to just suppress the warning at the usage sites while
discouraging future array designated intializers in new code.
Certain C Libraries have (unfortunately) included strings.h as a
part of string.h, which violates the POSIX spec for that specific
header. Some applications rely on this being the case, so let's
include it in our string.h
This was currently crashing Half-Life because it was a considered an
"Unknown" specifier. We can use the same case statement as the regular
hex format conversion (lower case 'x'), as the backend
to convert the number already supports upper/lower case input, hence
we get it for free :^)
This modifies sys$chown to allow specifying whether or not to follow
symlinks and in which directory.
This was then used to implement lchown and fchownat in LibC and LibCore.
Much like the existing in6addr_any global and the IN6ADDR_ANY_INIT
macro, our LibC is also expected to export the in6addr_loopback global
and the IN6ADDR_LOOPBACK_INIT constant.
These were found by the stress-ng port.
These POSIX APIs are defined as mapping directly to
`strrchr` and `strchr` respectively.
These are needed for the latest version of the stress-ng port,
and also give us better POSIX compliance.
These are aliases to `setjmp()` and `longjmp()` on our system,
as our implementations don't modify the signal mask.
This is required for the syzkaller executor process.
ISO C requires in section 7.2:
The assert macro is redefined according to the current state of NDEBUG
each time that <assert.h> is included.
Also add tests for `assert` multiple inclusion accordingly.
Most other syscalls pass address arguments as `void*` instead of
`uintptr_t`, so let's do that here too. Besides improving consistency,
this commit makes `strace` correctly pretty-print these arguments in
hex.
Add the `posix_madvise(..)` LibC implementation that just forwards
to the normal `madvise(..)` implementation.
Also define a few POSIX_MADV_DONTNEED and POSIX_MADV_NORMAL as they
are part of the POSIX API for `posix_madvise(..)`.
This is needed by the `fio` port.
This header defines various constants related to ethernet packets,
with ETH_ALEN being the length of an ethernet address (which is needed
by some ports).
We have close to zero usages of the C string functions in our codebase
(including the "safe" alternatives), so the deprecation warnings are
unlikely to have an actual effect on preventing large-scale use of the
"unsafe" functions.
Meanwhile, the deprecation warnings are causing issues for ports that
are compiled using -Werror by default, and are generally a large source
for logspam when compiling.
In order to reduce our reliance on __builtin_{ffs, clz, ctz, popcount},
this commit removes all calls to these functions and replaces them with
the equivalent functions in AK/BuiltinWrappers.h.
The actual value is unchanged, but the previous `0xffffffff` was an
unsigned value, which lead to clang getting mad at `foowc() == WEOF`.
This commit makes it a signed int on clang, which *should* serve
the same purpose and not lead to clang getting mad at us.
