Description Steve Langasek 2003-09-13 10:00:32 UTC
Samba 3.0.0rc1-rc4 all appear to suffer from a segfault when an attempt to
connect to a DC for enumeration of trusted domains fails.  There is a very
simple fix for the segfault, which I'll attach shortly.

This may be tied to a change of behavior in the handling of 'security=server'
between beta2 and rc1; the user reports that in at least one case, a server that
exhibits this problem under rc3 is able to successfully connect to the server
under rc1.

Fix for segfault upon failed attempt to enumerate trusted domains

On error, we may have a NULL pointer instead of a cli_state struct.  Check for
this in enumerate_domain_trusts() rather than passing the pointer to shutdown
functions that assume a validt struct.

Checked in.  Thanks vorlon!

originally reported against one of the 3.0.0rc[1-4] releases.
Cleaning up non-production versions.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
