69ebfe3495 Reinstate complete (and now correctly functioning) WARNS=2. 2001-09-12 19:15:02 +00:00

73bd08dda4 Back out (with prejudice) the last WARNS=2 fix. I cannot understand
its failure mode, and will revisit it later.

4239cf1c01 WARNS=2 fixes.
The remaining problem of converting highly incompatible pointer types
is done by "laundering" the value through a union.

This solves the problem (in my own mind) of how a "const char *" _ever_
actually gets a value in a WARNS=2 world.

WARNS=2 cannot be enable because of an unresolvable conflict in arg 2
of execv(). Document this in the Makefile.

5b3771f13c Deconvolute the authentication mess, and hand total responsiblity
for authentication to PAM. This meens that WHEELSU-type logic can
now be effected in the pam.conf "su" configuration stack. While here,
clean up the mess that the code had assumed over years of hacking by
folks using different styles. ANSIfy.

There is more policy in here that can be handed over to PAM. This will
be revisited.

e292984cd3 o Make comment match reality, synch code with comment.
o In practice: the comment indicates that all but umask and
  environmental variables of the users login class are applied when su
  occurs, unless -m is used to specify a class.  This was incorrect;
  in practice, the uid, gids, resources, and priority were set, and
  then resources and priority were selectively removed.  This meant
  that some aspects of the user context were not set, including handling
  of login events (wtmp, utmp), as well as the path specified in
  login.conf.
o I changed it so that the behavior is the same, but instead,
  LOGIN_SETALL is used, and appropriate flags are removed, including
  the LOGIN_SETLOGIN and LOGIN_SETPATH entries that were implicitly
  not present before.  I also updated the comment to reflect
  reality, selecting reality as the "correct" behavior.
o This has the practical benefit that as new LOGIN_SET* flags are
  introduced, they are supported by su unless specifically disabled.
  For example, of a LOGIN_SETLABEL flag is introduced to support
  MAC labels determined by the user's login class, then su no longer
  has to be modified.
o It might be desirable to have su use LOGIN_SETPATH depending on
  its command line parameters, as it might or might not be
  considered part of the "environment".

301afdb85c Changes for KTH KerberosIV.
Quieten -Wall a bit.

From Joe Traister:
 The previous patch did not propogate the KRBTKFILE environment variable
 into the new environment when -l is given to su, making it impossible
 for kdestroy to find the ticket file.  This patch corrects that problem
 as well as the original segfault problem.

f4390542d7 Kerberos can now deal with multi-homed clients.
Kerberos obtains a network address for the local host from the routing
tables and uses it consistently for all Kerberos transactions.  This ensures
that packets only leave the *authenticated* interface.  Clients who open
and use their own sockets for encrypted or authenticated correspondance
to kerberos services should bind their sockets to the same address as that
used by kerberos.  krb_get_local_addr() and krb_bind_local_addr() allow
clients to obtain the local address or bind a socket to the local address
used by Kerberos respectively.

99005ad98e Added support for an LCS-style `wheel su' which allows users in group wheel
to su to root by authenticating as themselves (using a password or S/Key)
rather than by using the root password.  This is useful in contexts like
ours, where a large group of people need root access to a set of machines.
(However, the security implications are such that this should not be
enabled by default.)

The code is conditionalized on WHEELSU.
