* libc: Always use our own copy of sys_errlist and sys_nerr (.so only).jilles2013-08-311-3/+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.

* Allow strerror(0) and strerror_r(0, ...).jilles2011-04-051-1/+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 withmike2002-12-181-85/+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.
