FIXES 60809
Problems fixed with this patch:
/1/ supergroup bug: when updating an entry in prdb, the logic in
pt_mywrite is supposed to unset flagged & found bitmap entries.
This failed on little-endian architecture machines.
/2/ warnings; a few fixes to eliminate some compiler noise.

the permission to obtain a write-lock is granted either by having the
"w" permission or the "i" when owning the file. The permission to obtain
a read-lock has been granted by having the "k" permission. However it
makes no sense that someone can obtain a write-lock but not a read-lock.
This patch grants permission to obtain read-locks to those who can obtain
write-locks.

(cherry picked from commit c5c23b7bc4544af2c1204622cd67b835b27bcdab)
Background: OpenAFS is vulnerable to crashing in the linux kernel symlink
code when running on kernel versions between 2.6.10 to 2.6.12. This also
includes all RHEL4 kernels, because RHEL4 includes the code from 2.6.10. The
problem is that the symlink text caching API, page_follow_link() et al, is
unsuitable for network filesystems where the page cache may be invalidated
in parallel with a path lookup.
This crash can be triggered easily by doing a bunch of path lookups
involving symlinks (e.g., stat() on various files pointed to through links),
while simultaneously running 'fs flushvol' on the volume containing the
symlinks.
The simplest way to fix this problem is to disable the use of symlink text
caching when the kernel does not provide a usable symlink API.

Based on Chris Wing's analysis which stated in part:
GFP_NOFS tells the allocator not to recurse back into the filesystem if it's
necessary to free up memory. However, vmalloc() does not have such an
option. Therefore, calling osi_Alloc() to request more than a page of
memory may end up recursing back into AFS to try to free unused inodes or
dentries.
In this case, what happened was that osi_Alloc() is called within an
AFS_GLOCK(); osi_Alloc() calls vmalloc() which tries to free dentry objects,
which then calls back into the AFS module. Unfortunately, AFS_GLOCK() is
already held and we deadlock.

The afskfw library contains an unprotected call to krb5_free_context
which can result in krb5_free_context being called with a NULL pointer.
MIT's Kerberos libraries do not check that the pointer is non-NULL and
will attempt to use it as a valid pointer which will in turn result
in an invalid memory access error.
This library is used by afslogon.dll which is loaded by winlogon.exe.
If the krb5 profile is invalid, the krb5_init_context call will fail
to allocate a krb5_context structure which can then result in
krb5_free_context being called with a NULL pointer.
An unhandled exception within winlogon.exe will cause a blue screen event
on Windows 2000, XP and 2003.

find lana by name is used by the afs control panel to populate the
lana list box. don't use the function to find by name. just use
it to generate the list of all lana names.

Remove the find lana by name functionality. It is crucial that the
name computed by the afs service can also be computed by the pioctl
function executed by generic end users without privilege. Unfortunately,
the undocumented functions used to implement find lana by name require
access to registry keys that a generic user cannot read.
