* Bump sys_errlist size to keep ABI backward-compatible for some time.Konstantin Belousov2018-12-271-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* libc: Always use our own copy of sys_errlist and sys_nerr (.so only).Jilles Tjoelker2013-08-311-3/+5
| | | | | | | | | | | | | | | | | | 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

* Allow strerror(0) and strerror_r(0, ...).Jilles Tjoelker2011-04-051-1/+1
| | | | | | | | | | | | | | | | Of course, strerror_r() may still fail with ERANGE. Although the POSIX specification said this could fail with EINVAL and doing this likely indicates invalid use of errno, most other implementations permitted it, various POSIX testsuites require it to work (matching the older sys_errlist array) and apparently some applications depend on it.

* Rearrange strerror() so that its itoa procedure can be used withMike Barcroft2002-12-181-85/+39
| | | | | | | | | | | | | | | | | | strerror_r(). Doing this allows us to ensure that strerror_r() always fills the supplied buffer regardless of EINVAL or ERANGE errors. strerror()'s semantics have changed slightly such that an argument of 0 is now considered invalid and errno is set to EINVAL. Remove internal regression test for strerror() and strerror_r(). This will be reincarnated in src/tools/regression/lib/libc/string. In strerror(3), add a comment about strerror()'s bogus return type.
