(by which they mean > 0). We were checking for negative numbers, but
not for 0. More by chance of the implementation than any specific design
(I suspect) "break 0" was being treated the same as "break" or "break 1".
Since 3 ways to achieve the same thing is overkill, let's do what posix
wants and forbid "break 0" and "continue 0".
use with mprotect(2), but without enabling them immediately.
Extend the mremap(2) interface to allow duplicating mappings, i.e.
create a second range of virtual addresses references the same physical
pages. Duplicated mappings can have different effective protections.
Adjust PAX mprotect logic to disallow effective protections of W&X, but
allow one mapping W and another X protections. This obsoletes using
temporary files for purposes like JIT.
Adjust PAX logic for mmap(2) and mprotect(2) to fail if W&X is requested
and not silently drop the X protection.
Improve test cases to ensure correct operation of the changed
interfaces.
- BUGFIX: Reinstore the NULL check in pam_end(3) which was removed in
OpenPAM Radula, as it breaks common error-handling constructs.
- BUGFIX: Return PAM_SYMBOL_ERR instead of PAM_SYSTEM_ERR from the
dispatcher when the required service function could not be found.
- ENHANCE: Introduce the PAM_BAD_HANDLE error code for when pamh is
NULL in API functions that have a NULL check.
- ENHANCE: Introduce the PAM_BAD_ITEM, PAM_BAD_FEATURE and
PAM_BAD_CONSTANT error codes for situations where we previously
incorrectly used PAM_SYMBOL_ERR to denote that an invalid constant
had been passed to an API function.
- ENHANCE: Improve the RETURN VALUES section in API man pages,
especially for functions that cannot fail, which were incorrectly
documented as returning -1 on failure.
============================================================================
OpenPAM Radula 2017-02-19
- BUGFIX: Fix an inverted test which prevented pam_get_authtok(3) and
pam_get_user(3) from using application-provided custom prompts.
- BUGFIX: Plug a memory leak in pam_set_item(3).
- BUGFIX: Plug a potential memory leak in openpam_readlinev(3).
- BUGFIX: In openpam_readword(3), support line continuations within
whitespace.
- ENHANCE: Add a feature flag to control fallback to "other" policy.
- ENHANCE: Add a pam_return(8) module which returns an arbitrary
code specified in the module options.
- ENHANCE: More and better unit tests.
