password must necessarily have an empty pwd->pw_passwd. Also add a check
that prevents users from setting a blank password unless the nullok option
was specified. Root is still allowed to give anyone a blank password.
to maintain, and had security issues which would have required a major
rewrite to address anyway.
This implementation currently starts a separate agent for each session
instead of connecting each new session to the agent started by the first
one. While this would be a Good Thing (and the old pam_ssh(8) tried to
do it), it's hard to get right. I'll revisit this issue when I've had a
chance to test some modifications to ssh-agent(1).
pam_wheel(8) module was written to work in spite of a broken libpam, and
has grown organically since its inception, which is reflected in both its
functionality and implementation. Rather than clean up pam_wheel(8) and
break backward compatibility, I've chosen to reimplement it under a new,
more generic name.

initialize the context. This way, a failure to initialize the context is
not fatal unless we actually have work to do - because if we don't, we
return PAM_SUCCESS without even trying to initialize the context.
pam_krb5 to consolidate the copyright texts. The semi-official
pam_krb5 module has been distributed with this new license text ever
since, but I'm just now getting around to updating the text here.
time_t. Deal with the possibility that time_t != int32_t. This boils
down to this sort of thing:
- time(&ut.ut_time);
+ ut.ut_time = time(NULL);
and similar for ctime(3) etc. I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

PAM module state (created in pam_sm_authenticate and referenced later
in pam_sm_setcred and pam_sm_acct_mgmt). However, the krb5_ccache
structure shares some data members with the krb5_context structure
that was used in its creation. Since a new krb5_context is created
and destroyed at each PAM entry point, this inevitably caused the
krb5_ccache structure to reference free'd memory.
Now instead of storing a pointer to the krb5_ccache structure,
we store the name of the cache (e.g. `MEMORY:0x123CACHE') in
pam_sm_authenticate, and resolve the name in the other entry points.
This bug was uncovered by phkmalloc's free'd memory scrubbing.

e.g.
Unknown error: -1765328378
we get
Client not found in Kerberos database
Another way to accomplish this would have been to leave
`error_message' alone, but to explicitly load the Kerberos com_err
error tables. However, I don't really like the idea of a PAM module
dorking with global tables.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.
Tested on: i386 (extensively), alpha
the PAM_ECHO_PASS option on-the-fly is a NOP (though it wasn't with the
old pam_get_pass(3) code). Instead, call pam_prompt(3) directly. This
actually simplifies the code a bit.

obscene, or - as they say in New York - sophisticated, add pam_echo(8) and

Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything. Added a NOINSTALLLIB knob for libpam/modules. To not
build any library at all, just do not set LIB.
via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files. Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.
Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1. Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):
kerberos5/lib/libtelnet/Makefile
lib/libbz2/Makefile
lib/libdevinfo/Makefile
lib/libform/Makefile
lib/libisc/Makefile
lib/libmenu/Makefile
lib/libmilter/Makefile
lib/libpanel/Makefile
Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.
Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD. Similarly for INCOWN, INCGRP,
and INCMODE.
Consistently use INCLUDEDIR instead of /usr/include.
gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.
These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".
- add __unused where appropriate
- PAM_RETURN -> return since OpenPAM already logs the return value.
- make PAM_LOG use openpam_log()
- make PAM_VERBOSE_ERROR use openpam_get_option() and check flags
for PAM_SILENT
- remove dummy functions since OpenPAM handles missing service
functions
- fix various warnings
