* Oops: the caching of TCB address in single-threaded processes on archs withguenther2016-05-101-2/+2
| | | | slow TCB_GET (alpha, arm, mips64, sh) was broken when I switched CPP symbols.
* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-073-135/+252
| | | | | | | | | | | | | | | | | This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@

* Allow setenv(3) and putenv(3) to operate on a NULL environ pointer.millert2016-04-251-11/+15
| | | | | | The getenv(3) and unsetenv(3) functions already support this. This will make it easier to emulate the glibc clearenv() function in ports. Based on a diff from and OK jca@

| | | | | | | | | | | | correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

* Remove sentences in RETURN VALUES sections saying that functions withmmcc2016-03-124-25/+8
| | | | | | | | | | | | | 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@

* Fix err(3) calls after allocation failures in examples.schwarze2016-02-051-8/+8
| | | | | | 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@.
* Don't crash dumping malloc stats if malloc_init hasn't been called, noted byotto2016-01-261-1/+3
| | | | David CARLIER
* Long ago, malloc internally had two kinds of failures, warnings and errors.tedu2016-01-062-14/+7
| | | | | | | | 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

* Integrate two patches originally from Daniel Micay.tedu2015-12-091-8/+76
| | | | | | | | | | | | 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
