[Pkg-utopia-maintainers] New PAM in experimental needs testing

[Roger Leigh]

Hi folks,

A new version of PAM (0.99.7.1-1) has been packaged and uploaded to
experimental.  This is intended to replace 0.79-4.  However, because
there have been quite a number of upstream changes, and all the
Debian-specific patches against the old one were painstakingly
re-diffed and updated by hand, and because a broken PAM means a rather
broken system, this new version needs some wider testing before it is
suitable for unstable.

The work for this was done by myself and Jan Christoph Nordholz, who
rewrote the @include patch, fixing a memory leak in the current code,
as well as doing a lot of testing, building and general reviewing of
the PAM packaging.  It's thanks to Jan that it's ready for wider
review, since I did all the rediffing back in April, but lacked time
to squash the last few bugs.

If anyone could take the time to install it, test all the services
using PAM for authentication/authorisation still work as expected, and
report any defects, that would be much appreciated.  If you want to
avoid breaking your system, it is advisable to install into a chroot.
However, we have tested that basic functionality does work (su and
passwd in particular), so it should be safe to install for real (but
no guarantees are given).

Additionally, all of the packages which Build-Depend, Depend or
Recommend PAM packages should be tested against the new packages.  A
complete list is given below, and the maintainer's Bcc'd with this
message.


If you do hack on the PAM sources, note that the dpatch patch order is
important--later patches do rely on earlier patches being present.
Also, you need to run "debian/rules patch|unpatch" by hand, due to the
need to re-bootstrap the autotools.  To do that "debian/rules
bootstrap" will do everything consistently, providing the patches are
applied.


Some bits which need wider review and discussion:

Several of the Debian-specific patches should probably be removed.
For example, the @include (Debian-specific) syntax should be replaced
by the include mechanism added by upstream; we should make this a
release goal for Lenny IMO.  Maintaining Debian-specific hacks imposes
a real burden on the PAM maintainers--it took over 15 man hours to do
the main re-diffing, and the same again to get it working, which is
ridiculous and error-prone.  We could easily be introducing
Debian-specific security bugs by doing so.  Some checks such as the
obscure checks for pam_unix and chroot limits for pam_limits should be
dropped (who uses this functionality)?  The obsure checks appear to
predate PAM, but should cracklib not be the replacement?  This
non-standard stuff should really be deprecated, obsoleted, then
dropped.  What do other people think about this?

The remaining patches should then really be pushed upstream, which
possible now we are synched with their latest stable release.

One other note: upstream now default to enabling cracklib in pam_unix
(in addition to pam_cracklib), which causes passwd to do all the extra
checks cracklib does.  This has been disabled for now after discussion
with Jan, because it brings in quite a few dependencies into base, and
may not be generally wanted.  It also breaks passwd if you don't have
cracklib-runtime *and* a wordlist *and* run update-cracklib, so this
needs some fixing of dependencies and coordination to do properly.  It
might be worth re-adding, if there was consensus for that.  I'm not
yet sure how this differs from the pam_cracklib functionality,
however.


Regards,
Roger
