* Reduce instances of `` '' in manuals.bentley2014-11-151-5/+5
| | | | | | | | | | | | troff displays these as typographic quotes, but nroff implementations almost always print them literally, which rarely has the intended effect with modern fonts, even in stock xterm. These uses of `` '' can be replaced either with more semantic alternatives or with Dq, which prints typographic quotes in a UTF-8 locale (but will automatically fall back to `` '' in an ASCII locale). improvements and ok schwarze@

* Revamp malloc.3 by reordering the sections and rewriting parts.doug2014-10-191-185/+417
| | | | | | | | | | | | | | | | | | | | | | | | | | | The old man page had a lot of useful information, but it was all mixed together which made it difficult to reference. The main theme in this commit is that the sections are more focused: * DESCRIPTION describes the overall behavior * RETURN VALUES describes what it may return (including implementation defined values) * EXAMPLES shows why we recently started an audit on malloc and realloc usage in the tree. * Added CAVEATS which describes what is implementation defined, gotchas and security implications of misusing these functions * Added IDIOMS which describes how these functions should or should not be used The MALLOC_OPTIONS section was left unchanged. Function names were added to DIAGNOSTICS and STANDARDS. The MALLOC_OPTIONS and DIAGNOSTICS sections were pushed down in the page so more pertinent information is higher up. This has gone through several revisions thanks to input from deraadt@ and schwarze@. Ingo also helped with some of the mandoc formatting. OK schwarze@ (as far as it is a good starting point and the code snippets look ok)

* using reallocarray() gives us multiplicative integer overflow checkingderaadt2014-10-081-3/+3
| | | | | | | | | | in case something wants to create massive amounts of environment, like a bit more than 1/4 of a 32-bit address space. unrealistic -- but why audit one code path, and not treat others the same? then you have to re-engage everytime you see the code. read the news, that isn't what developers do. At least if the code paths look the same, there is hope, because they are easier to verify for correctness. developers need to give other developers a chance to want to care.

* Do not claim that empty numbers set EINVAL, our implementation doesn't.schwarze2014-09-142-37/+61

| | | | | | | | | | required by the C standard when called with an invalid base: strtoll(), strtoimax(), strtoul(), strtoull(), and strtoumax(). Same behaviour for strtoq() and strtouq() even though not standardized. No functional change in strtol(), it was the only one already correct. While here, simplify the conditional expression for checking the base and sync whitespace and comments among the six files. ok millert@

* Change _rs_allocate so it can combine the two regions (rs and rsx)deraadt2014-07-192-28/+25
| | | | | | | | | | into one if a system has an awesome getentropy(). In that case it is valid to totally throw away the rsx state in the child. If the getentropy() is not very good and has a lazy reseed operation, this combining is a bad idea, and the reseed should probably continue to use the "something old, something new" mix. _rs_allocate() can accomodate either method, but not on the fly. ok matthew
