* In ingo's new world order, we do not want multiple manual pages describingderaadt2014-12-093-247/+3
| | | | | | | 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)
* Replace all 14 instances of .St -ansiC-99 in our tree with .St -isoC-99.schwarze2014-11-301-3/+3
| | | | | | 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.
* restructure libc/string + libc/arch/*/string coperation regardingderaadt2014-11-308-155/+309
| | | | | | | | | | | | | | | | (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

* Protect explicit_bzero() from link-time optimizationmatthew2014-06-211-7/+10
| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | 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
