Windows: Revise SMB QuerySecurityInfo for MS10-020
MS10-020 (http://support.microsoft.com/kb/980232) has caused
many problems for implementors of SMB 1.0 servers and applications
that call GetFileSecurity() without checking the return code to
determine if the call succeeded. The gist of the vulnerability
was that the SMB redirector would pass any buffer it received
to the application regardless of whether or not it was valid.
MS10-020 protects the applications by strictly validating the
SMB response data structure and the data in the security descriptor
that is returned.
The problem for SMB 1.0 server implementors is that there have
been at least three different protocol descriptions for
NT_TRANSACT_QUERY_SECURITY_DESC published over the last decade
and all of them are incomplete. Therefore, just about no one but
Microsoft has an SMB 1.0 server implementation that produces the
exact out that they are expecting to validate.
The end result is that in an attempt to protect applications from
crashing due to invalid input being passed in directly caused
dozens of applications to crash by not returning any security
descriptor data at all. Even when the applications didn't crash
they might not have been able to save their data. Cisco WAAS
and NetApp DataOnTap systems were most adversely affected and
they have had CIFS protocol licenses for many many years.
To fix OpenAFS here is what needed to be done:
1. Instead of returning a security descriptor that gives ownership
to the NUL SID, give it to the Everyone SID and set the flag
that states that everyone has full access.
2. Validate the input parameters. In particular, check to ensure
that the SMB file descriptor is valid and the file has not
been deleted.
3. Enforce the maximum output data and parameter counts.
4. Handle buffer overflow and buffertoosmall conditions
in the manner that Microsoft expects them to be handled.
In particular, note that the parameter data which is returned
in the SMB Data Region is not counted in the Data Count.
Even if MaxData is 0, we can still return parameters values
as long as MaxParm is large enough.

Comprehensive edit of Admin Guide chapter two (first 20%)
Update and revise chapter two (Issues in Cell Configuration and
Administration) of the Administration Guide for current AFS and current
computing concepts.
Remove references to an AFS-provided login utility and discuss local login
configuration for Kerberos more generically. Further clarify the role of
ssh in ensuring the user has access to files in AFS during remote login.
Improve the inode and namei discussion slightly. Update the setuid
discussion for the new default of disabling setuid for cells and for the
known security flaws in enabling setuid. Modernize terminology for DNS
around cell naming and remove the descriptions of TLDs. We can now assume
our target audience knows this stuff.
Move index terms into the appropriate section for what's being indexed in
a few more cases.
Lots of other, more minor wording changes and updates.
this code makes us work in the face of a sub1500 mtu network.
a subsequent commit is needed to make it more effective: attempts
to grow the mtu must be scheduled so we aren't forced to heavily
brute-force on failure to discover the exact mtu immediately;
for performance, we do want to grow to the real mtu.

Windows: Support building a lite-client installer
If LITECLIENT is defined when invoking the WiX based MSI installer
build, we will build a light-weight client installer MSI. This
minimizes the size of the installer for users who only need client
functionality from OpenAFS.
The light-weight client excludes:
- Server components
- Control center components
- Administration utilities
- Debug symbols
Lite-client installer can also be built by invoking target wix-lite
from the root NTMakefile.
"fs checkservers" during cache creation can crash client
Many pioctl calls pass as soon as the afs_resourceinit_flag is set,
which happens relatively early, alas before the cell name is set.
PCheckServers and others need the latter and dereference NULL.
Easiest: set the cell name as soon as it is known and the dynroot initialisation
piggy-backed to it can be done.

Windows: Fix usage of cm_FreeServerList
cm_FreeServerList will set the input variable to NULL if the
contents of the list could in fact be freed. If they could not
be freed, the individual entries are marked for deletion and will
not be subsequently used. Do not set the list variable to NULL
after calling cm_FreeServerList otherwise memory can be leaked.
