David CARLIER

Long ago, malloc internally had two kinds of failures, warnings and errors.

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

Remove NULL-checks before free() and a few related dead assignments.

ok and valuable input from millert@

Simplify return call of rand() and rand_r() to make it easier to read.

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@

tiny sanity check on file size

Integrate two patches originally from Daniel Micay.

2015-12-09T02:45:23+00:00

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
