* After read errors, fgetln(3) sometimes succeeded (returning non-NULL)schwarze2016-08-251-3/+6
| | | | | | | | | | | | and failed (setting errno and ferror(3)) both at the same time. That's a bad idea in general, and here in particular since returning partial lines was neither reliable (sometimes, you got NULL anyway) nor predictable (almost always, the line would be truncated long before the actual read error). Instead, on read failure, fail properly and always return NULL. Issue found in a discussion with Andrey Chernov <ache at freebsd dot org> who finally agreed to move FreeBSD into the same direction. The fix is joint work with and OK by millert@.
* Add framework for resolving (pun intended) libc namespace issues, usingguenther2015-08-311-1/+2
| | | | | | | | | | | | wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here. tests clean on i386, amd64, sparc64, powerpc, and mips64 naming feedback from kettenis@ and millert@ ok kettenis@

* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-9/+12
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.
