2016-03-12Remove sentences in RETURN VALUES sections saying that functions withmmcc
void return types 'return no value'. This is obvious and therefore unneccessary to mention. We spare rewind(3)'s sentence because espie@ pointed out that it's a warning - the function masks a potential error. This commit also adds a sentence to X509_free clarifying that it's NULL-safe. This bit was discussed with doug@. ok martijn@, sentiment supported by schwarze@

2016-02-05Fix err(3) calls after allocation failures in examples.Ingo Schwarze
There is long-standing consensus that err(1, NULL) is the best idiom after failure of malloc(3) and friends. Quirk in the manual noticed by tb@.

2016-01-06Long ago, malloc internally had two kinds of failures, warnings and errors.Ted Unangst
The 'A' option elevated warnings to errors, and has been the default for some time. Then warnings were effectively eliminated in favor of everything being an error, but then the 'a' flag turned real errors into warnings! Remove the 'a' option entirely. You shouldn't have used it anyway. ok tb tdeval

2015-12-18Simplify return call of rand() and rand_r() to make it easier to read.tb
This is slightly less robust, but RAND_MAX must be one below a power of two in both variants anyway. Based on a suggestion by Matthew Martin. ok tedu@
2015-12-10tiny sanity check on file sizeTed Unangst
2015-12-09Integrate two patches originally from Daniel Micay.Ted Unangst
1. Optionally add random "canaries" to the end of an allocation. This requires increasing the internal size of the allocation slightly, which probably results in a large effective increase with current power of two sizing. Therefore, this option is only enabled via 'C'. 2. When writing junk (0xdf) to freed chunks (current default behavior), check that the junk is still intact when finally freeing the delayed chunk to catch some potential use after free. This should be pretty cheap so there's no option to control it separately. ok deraadt tb

2015-11-10libc.so can't be unloaded, so move the hidden atexit() and pthread_atfork()Philip Guenther
stubs for the executable from crtbegin.o into libc, which lets them be excluded from static links that don't use them. For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini sections for libc aren't called at the right times anyway, so it's good that they're unused. libc.so just needs __guard_local and the .note.openbsd.ident section, so add them to stack_protector.c for now (this will be improved) "good time" deraadt@
2015-10-25Move the _atfork_list definition to atexit.c so that the fork syscall stubPhilip Guenther
doesn't get pulled into all static executables ok millert@ jca@
2015-10-25Hide __atexit and __atexit_register_cleanup()Philip Guenther
Wrap __cxa_{atexit,finalize}() so the call from exit() goes direct Switch regress/lib/libc/atexit/ to be built with -static so that it can still access __atexit* ok millert@ jca@
2015-10-25Use sigaction() instead of signal() to avoid pulling in unnecessaryPhilip Guenther
wrappers. To keep uses from crawling back in, mark signal() as deprecated inside libc. ok deraadt@
2015-10-23Loop the waitpid() on EINTR, and save and restore the disposition ofPhilip Guenther
SIGINT and SIGQUIT with sigaction() instead of signal() so that all bits are preserved. ok deraadt@ millert@
2015-10-23Merge the sigaction() and sigprocmask() overloads/wrappers from libpthreadPhilip Guenther
into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@
2015-10-13In rev 1.15 the sizeof argument was fixed in a strlcat() call butTodd C. Miller
the truncation check immediately following it was not updated to match. Not an issue in practice since the buffers are the same size. OK deraadt@
2015-10-01Eliminate the last of the LINTEDn and PRINTFLIKEn comments. In onePhilip Guenther
case, by deleting some useless '& of an array' we also eliminate the need for the casts which prompted the original lint warnings ok deraadt@

2015-09-13Wrap <stdlib.h> so that calls go direct and the symbols not in thePhilip Guenther
C standard are all weak. Apply __{BEGIN,END}_HIDDEN_DECLS to gdtoa{,imp}.h, hiding the arch-specific __strtorx, __ULtox_D2A, __strtorQ, __ULtoQ_D2A symbols.

variables go direct. (Common variables cannot be aliased.)
2015-09-10Pull in namespace.h when building all .c files using gcc's -include option,Philip Guenther
so that we can provide asm labels for the memcpy/memset/__stack_smash_handler calls that it generates ab initio. Eliminate direct #includes of it. Make sure it's a dependency of all objects (unnecessary for asm, but close enough). ok deraadt@
