syslog: Improve fortify with clang

2024-02-27T13:52:59Z

It improve fortify checks for syslog and vsyslog. The compile and runtime hecks have similar coverage as with GCC. The syslog fortify wrapper calls the va_arg version, since clang does not support __va_arg_pack. Checked on aarch64, armhf, x86_64, and i686. Reviewed-by: Carlos O'Donell Tested-by: Carlos O'Donell

misc/bits/syslog.h: Clearly separate declaration from definition

2023-07-05T14:59:48Z

This allows to include bits/syslog-decl.h in include/sys/syslog.h and therefore be able to create the libc_hidden_builtin_proto (__syslog_chk) prototype. Reviewed-by: Siddhesh Poyarekar

misc/bits/select2.h: Clearly separate declaration from definitions

2023-07-05T14:59:48Z

The __fdelt_chk declaration needs to be available so that libc_hidden_proto can be used while not redefining __FD_ELT. Thus, misc/bits/select-decl.h is created to hold the corresponding prototypes. Reviewed-by: Siddhesh Poyarekar

Apply asm redirections in syslog.h before first use [BZ #27087]

2022-11-29T18:07:22Z

Similar to d0fa09a770, but for syslog.h when _FORTIFY_SOURCE > 0. Fixes [BZ #27087] by applying long double-related asm redirections before using functions in bits/syslog.h. Tested with build-many-glibcs.py. Reviewed-by: Adhemerval Zanella

I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

Prepare redirections for IEEE long double on powerpc64le

2020-02-17T21:28:29Z

All functions that have a format string, which can consume a long double argument, must have one version for each long double format supported on a platform. On powerpc64le, these functions currently have two versions (i.e.: long double with the same format as double, and long double with IBM Extended Precision format). Support for a third long double format option (i.e. long double with IEEE long double format) is being prepared and all the aforementioned functions now have a third version (not yet exported on the master branch, but the code is in). For these functions to get selected (during build time), references to them in user programs (or dependent libraries) must get redirected to the aforementioned new versions of the functions. This patch installs the header magic required to perform such redirections. Notice, however, that since the redirections only happen when __LONG_DOUBLE_USES_FLOAT128 is set to 1, and no platform (including powerpc64le) currently does it, no redirections actually happen. Redirections and the exporting of the new functions will happen at the same time (when powerpc64le adds ldbl-128ibm-compat to their Implies.
