2014-12-12catch up with swab.c rev. 1.9:Ingo Schwarze
update SYNOPSIS and DESCRIPTION and add STANDARDS
2014-12-11update swab() to match the current posix definition. "rationale: none."Ted Unangst
rewrite the function to be simpler as well. the compiler can unroll the loop for us if necessary. ok schwarze
2014-12-09no more string(3);Jason McIntyre
2014-12-09In ingo's new world order, we do not want multiple manual pages describingTheo de Raadt
the same thingies. Therefore these "lists of functions" man pages can go away. Hurray! I've wanted these pages to die for around 10 years! ok ingo (and i think jmc)
2014-11-30Replace all 14 instances of .St -ansiC-99 in our tree with .St -isoC-99.Ingo Schwarze
The former is not used anywhere in NetBSD, FreeBSD, or DragonFly and not supported by groff, so i'm going to delete it from mandoc(1). We don't need two macros for the same thing.
2014-11-30restructure libc/string + libc/arch/*/string coperation regardingTheo de Raadt
(potentially) MD versions (function dependent, not filename dependent) split out memcpy/memmove/bcopy and strchr/index/strrchr/rindex Bring back amd64 .S versions And the final touch: switch all architectures temporarily to MI memcpy.c, which contains syslog + abort for overlapping copies. A nice harsh undefined behaviour. We will clean the entire userland of the remaining issues in this catagory, then switch to the optimised memcpy which skips the memmove check. I tried to cut this change into pieces, but testing each sub-step on every architecture is too time consuming and mindnumbing. ok miod
2014-10-11Since deraadt@ remembers seeing strdup() on one particular 4.2BSD machine,Ingo Schwarze
i looked a bit closer and found instances before Reno, so correct HISTORY.

artificially constrain alternative implementations. ok deraadt
2014-06-21Protect explicit_bzero() from link-time optimizationMatthew Dempsky
Modern compiler toolchains are capable of optimizing even across translation unit boundaries, so simply moving the memory clearing into a separate function is not guaranteed to clear memory. To avoid this, we take advantage of ELF weak symbol semantics, and insert a call to an empty, weakly named function. The semantics of calling this function aren't determinable until load time, so the compiler and linker need to keep the memset() call. There are still ways a toolchain might defeat this trick (e.g., optimistically expecting the weak symbol to not be overloaded, and only calling memset() if it is; promoting weak symbols to strong symbols at link-time when emitting a static binary because they won't be interposed; implementing load-time optimizations). But at least for the foreseeable future, these seem unlikely. ok deraadt

2013-06-01Fix catopen(3) for UTF-8 locales and update the implementation to POSIX-2008.Stefan Sperling
Catalogs had an arbitrary character set which was used regardless of locale. Add UTF-8-encoded catalogs for libc error messages, and rename existing ones to indicate their character sets. catopen(3) now chooses a catalog which matches the locale's encoding, if available. help & ok matthew, man page bits ok jmc, input from naddy and bluhm

explaining of "what a C string is", and make it more clear that these functiosn BEHAVE EXACTLY LIKE snprintf with "%s"! (anyone who wants to write a 'strlcpy considered harmful' paper should probably write a 'strlcpy and snprintf considered harmful' paper instead). note to those from other projects reading this commit message: It would be very good if this new manual was picked up in your project. ok jmc millert krw
