Chain caching is a feature of Linux-PAM, where pam_authenticate() and
pam_open_session() "freeze" the chain so that their companion
primitive (pam_setcred() and pam_close_session() respectively) will
call the exact same modules, skipping those that failed in the
previous call.
There are several reasons not to do this, the most prominent of which
is that it makes it impossible to call pam_setcred() without first
calling pam_authenticate() - which is perfectly valid according to
DCE/RFC 86.0 and XSSO, and is necessary to make 'login -f' work.
Instead of chain caching, implement something similar to the way
Solaris' libpam behaves: pam_setcred treats "sufficient" modules as if
they were "required", i.e. does not break the chain when they succeed.
PAM modules whose pam_sm_setcred() should not be called unless their
pam_sm_authenticate() succeeded can simply set a state variable using
pam_set_data() in pam_sm_authenticate(), and use pam_get_data() to
check it in pam_sm_setcred().

problem, it still didn't DTRT for services that did not have a service-
specific policy if /etc/pam.d existed but did not contain an "other"
policy. This fixes the problems some people have experienced with sudo.
And I almost didn't have to use goto.
The current configuration sequence is:
1) Look for /etc/pam.d/foo
2) If PAM_READ_BOTH_CONFS is defined, or step 1) failed, look for
foo in /etc/pam.conf
3) Look for /etc/pam.d/other (to fill in the gaps)
4) If PAM_READ_BOTH_CONFS is defined, or step 3) failed, look for
other in /etc/pam.conf
I believe this is the intended behaviour of the original code. The least
surprising behaviour seems to be when PAM_READ_BOTH_CONFS is not defined -
/etc/pam.d/foo will be preferred over /etc/pam.conf, but the latter will
serve as a backup if the former does not exist.

I don't recall why the rev 1.2 hack is needed. It looks like Amd was

decrease the maintenance effort.

When rtld runs the .fini section in a shared lib (C++), the code in
question from .../contrib/gdb/config/alpha/crtbegin.asm first calls
__do_globals_dtors_aux and then __do_frame_takedown. Unfortunately, the
value of gp after a jsr is undefined and in this case had changed from before
the call, probably as a result of calling code in some other shared library.
The normal calling convention for alpha is to re-initialize gp using
'ldgp gp,0(ra)' after a jsr instruction but in this case no such
re-initialization is done. This leads to a bogus value being read for the
address of __do_frame_takedown and a quick segfault.

I am not sure who thought that making FreeBSD depend on ISC's libbsd
was a sensible thing to do.
Thus I have ripped out the define of gettimeofday() and isc__gettimeofday()
out of this file, since we:
1) Don't use nor build libbsd (FreeBSD might give a hint in its name as to
why)
2) Our gettimeofday() is the same in semantics as prototyped in ISC's
libbsd.
This was something which could have been fixed before it was released if
we had at least some insight into the development process. But my praying
fell on deaf ears it seems.
Of course, if I am wrong I welcome the corrections to my thinking, gladly
even.
