We have to drop support for not_set_pass option which is not much useful
anyway. Instead we get proper support for authtok_type option.
* modules/pam_unix/pam_unix.8.xml: Removed not_set_pass option, added authtok_ty
pe
option.
* modules/pam_unix/pam_unix_auth.c (pam_sm_authenticate): Replace _unix_read_pas
sword()
call with equivalent pam_get_authtok() call.
* modules/pam_unix/pam_unix_passwd.c (pam_sm_chauthtok): Likewise and also drop
support for not_set_pass.
* modules/pam_unix/support.c (_unix_read_password): Remove.
* modules/pam_unix/support.h: Remove UNIX_NOT_SET_PASS add UNIX_AUTHTOK_TYPE.

* modules/pam_unix/pam_unix.8.xml: Document the no_pass_expiry option.
* modules/pam_unix/pam_unix_acct.c (pam_sm_acct_mgmt): If no_pass_expiry
is on and return value data is not set to PAM_SUCCESS then ignore
PAM_NEW_AUTHTOK_REQD and PAM_AUTHTOK_EXPIRED returns.
* modules/pam_unix/pam_unix_auth.c (pam_sm_authenticate): Always set the
return value data.
(pam_sm_setcred): Test for likeauth option and use the return value data
only if set.
* modules/pam_unix/support.h: Add the no_pass_expiry option.

Security fix: CVE-2015-3238
If the process executing pam_sm_authenticate or pam_sm_chauthtok method
of pam_unix is not privileged enough to check the password, e.g.
if selinux is enabled, the _unix_run_helper_binary function is called.
When a long enough password is supplied (16 pages or more, i.e. 65536+
bytes on a system with 4K pages), this helper function hangs
indefinitely, blocked in the write(2) call while writing to a blocking
pipe that has a limited capacity.
With this fix, the verifiable password length will be limited to
PAM_MAX_RESP_SIZE bytes (i.e. 512 bytes) for pam_exec and pam_unix.
* NEWS: Update
* configure.ac: Bump version
* modules/pam_exec/pam_exec.8.xml: document limitation of password length
* modules/pam_exec/pam_exec.c: limit password length to PAM_MAX_RESP_SIZE
* modules/pam_unix/pam_unix.8.xml: document limitation of password length
* modules/pam_unix/pam_unix_passwd.c: limit password length
* modules/pam_unix/passverify.c: Likewise
* modules/pam_unix/passverify.h: Likewise
* modules/pam_unix/support.c: Likewise
