* libc: Purge unneeded cdefs.hWarner Losh2023-11-011-1/+0
| | | | | | | | | These sys/cdefs.h are not needed. Purge them. They are mostly left-over from the $FreeBSD$ removal. A few in libc are still required for macros that cdefs.h defines. Keep those. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D42385

| | | | | | | | | The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix
* Bump sys_errlist size to keep ABI backward-compatible for some time.Konstantin Belousov2018-12-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Addition of the new errno values requires adding new elements to sys_errlist array, which is actually ABI-incompatible, since ELF records the object size. Expand array in advance to 150 elements so that we have our users to go over the issue only once, at least until more than 53 new errors are added. I did not bumped the symbol version, same as it was not done for previous increases of the array size. Runtime linker only copies as much data into binary object on copy relocation as the binary'object specifies. This is not fixable for binaries which access sys_errlist directly. While there, correct comment and calculation of the temporary buffer size for the message printed for unknown error. The on-stack buffer is used only for the number and delimiter since r108603.

* libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-251-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326193

* libc: Always use our own copy of sys_errlist and sys_nerr (.so only).Jilles Tjoelker2013-08-311-0/+43
This ensures strerror() and friends continue to work correctly even if a (non-PIE) executable linked against an older libc imports sys_errlist (which causes sys_errlist to refer to the executable's copy with a size fixed when that executable was linked). The executable's use of sys_errlist remains broken because it uses the current value of sys_nerr and may access past the bounds of the array. Different from the message "Using sys_errlist from executables is not ABI-stable" on freebsd-arch, this change does not affect the static library. There seems no reason to prevent overriding the error messages in the static library. Notes: svn path=/head/; revision=255108
