====================
remove bogus makefile
====================
stop bos bnodes before deleting
move dump tools directly into test suite as that is their intended use
canonical versions of these tools will be distributed otherwise
and may be updated but these provide the minimum functionality
Fix the two places in Solaris afs_GetOnePage where locks
are obtained/released without GLOCK.

"1. The default Open AFS is set to normal security (doesn't generate random
user names).
If you are installing over a previous version (before 1.2.2b) it's default
is
high security; therefore, if you want the normal security, you should
uninstall the previous version (1.2.2a or earlier) and select to 'Not
Preserve previous settings'.
To manually change security you need to set the following registry keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemond\NetworkProvider
LogonOptions = 1 - Integrated Logon
LogonOptions = 2 - High Security options, Random User name generation
LogonOptions = 3 - both
3. Windows 2000/NT, Win9x - First time installations will create necessary
directories when user decides to download CellServDB
4. Windows 2000/NT, Global Drive working.
5. Windows XP - Drive mapping via GUI working.
6. Rename pthread.dll to afspthread.dll"

like openbsd, stripping on netbsd strips libraries
based on suggestion from Ted Anderson
"the changes make more sense
than the code as it currently exists. the only think i am nervous
about is the dontSleep delete. while it makes more sense to just
not wakeup sleepers if none exist, i suppose its possible that
some bit of afs code wants acausal (wake before sleep) events.
that does seem quite unlikely. just looking at the sleep on
solaris, it checks the seq number to get the next event not
a previous event.
i imported the changes and make the fixup in osi_stoplistener().
i dropped some of the silly syntax changes that junked up the
diff -- this makes it a bit easier to see what was changed.
i just added an assert in afs_addevent for quality assurance
purposes."

fix for osi_StopListener so it does the rigth thing
"The first is to change the gfp_mask passed to kmalloc(). Using GFP_KERNEL,
it is possible that the VM will call back to the filesystem to free up
memory to satisfy the kmalloc request. GFP_NOFS will prevent this possible
recursion. I believe GFP_NOFS first appeared in the 2.4.6 kernel.
The second change involves the call to schedule() when vmalloc() fails. This
can also cause a hang. The schedule() call could be replaced with:
set_current_state(TASK_INTERRUPTIBLE);
schedule_timeout(HZ);"
"This fixes a livelock condition introduced in my earlier
resource starvation patch; apparently I had erred too far
on the side of "wake up just in case". The livelock bug
is exhibited when running 10 fsstress processes at once;
if many processes are waiting for a new Rx call, they get
stuck in an uninterruptible kernel loop waking each other
up."
"This patch fixes a deadlock in the new dcache locking scheme.
The underlying bug apparently existed before, but due to the
absence of locking, it probably resulted in spuriously high
refcounts rather than deadlock.
The problem happens when there are zero-length dcache entries
associated with a file; this is demonstrated by fsx, which
hangs after running on AFS for a while. The writeback loop
never releases dcache entries unless they're stored back to
the server as part of a sequential byte range."
"The particular problem seems to be, when size
is computed to be zero, tsmall is not filled in with valid data,
and ProcessFS is called with a zeroed out OutStatus. This causes
the file to magically turn into a directory (VDIR), among other
things"
"The second part of the patch doesn't fix any bug that I've ran into
thus far, but seemed like a good idea while I was reading the code
to find the former bug."
Currently it's possible to give StoreData negative Pos/Length/FileLength
arguments and thereby set the volume quota usage to arbitrary values.
This patch makes these values unsigned, since negative file positions
and lengths don't make sense anyway.
no reason server etcdir needs to be forced world readable; nothing need
default to those cellconfig files except in the localauth case and then
you need to be able to read the KeyFile anyway
This patch implements more fine-grained locking for dcache entries.
The main advantage is that multiple chunks of the same file can be
fetched at once. This means that an incorrectly-guessed prefetch
won't block other fetches, prefetches of multiple chunks can occur
in parallel, and multiple processes sharing the same file can read
from different parts of the file at once.
This patch fixes a resource starvation condition in Rx. The
problem arises, for instance, when more than 4 daemons try to
prefetch chunks of the same file at once. The fifth daemon is
stuck in MAKECALL_WAITING state, never getting a chance to run,
because the other 4 daemons never yield to the scheduler after
releasing the call, and just grab the call back again.
afs_RemoveCellEntry holds afs_xcell; setserverprefs modified the same
structure but did not which was problematic if something changed out from under
it
