[PATCH] knfsd: Allow lockd to drop replies as appropriate
It is possible for the ->fopen callback from lockd into nfsd to find that an
answer cannot be given straight away (an upcall is needed) and so the request
has to be 'dropped', to be retried later. That error status is not currently
propagated back.
So:
Change nlm_fopen to return nlm error codes (rather than a private
protocol) and define a new nlm_drop_reply code.
Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply
when this error comes back.
Cause svc_process to drop a request which returns a status of
rpc_drop_reply.

[PATCH] knfsd: Fix bug in recent lockd patches that can cause reclaim to fail
When an nfs server shuts down, lockd needs to release all the locks even
though the client still holds them.
It should therefore not 'unmonitor' the clients, so that the files in nfs/sm
will still be there when the nfs server restarts, so that those clients will
be told to reclaim their locks.
However the hosts are fully unmonitored, so statd may well remove the files.
lockd has a test for 'sm_sticky' and avoid the unmonitor call if it is set,
but it is currently not set.
So set it when tearing down lockd.

[PATCH] knfsd: nfsd4: fix owner-override on open
If a client creates a file using an open which sets the mode to 000, or if a
chmod changes permissions after a file is opened, then situations may arise
where an NFS client knows that some IO is permitted (because a process holds
the file open), but the NFS server does not (because it doesn't know about the
open, and only sees that the IO conflicts with the current mode of the file).
As a hack to solve this problem, NFS servers normally allow the owner to
override permissions on IO. The client can still enforce correct
permissions-checking on open by performing an explicit access check.
In NFSv4 the client can rely on the explicit on-the-wire open instead of an
access check.
Therefore we should not be allowing the owner to override permissions on an
over-the-wire open!
However, we should still allow the owner to override permissions in the case
where the client is claiming an open that it already made either before a
reboot, or while it was holding a delegation.

[PATCH] fuse: fix handling of moved directory
Fuse considered it an error (EIO) if lookup returned a directory inode, to
which a dentry already refered. This is because directory aliases are not
allowed.
But in a network filesystem this could happen legitimately, if a directory is
moved on a remote client. This patch attempts to relax the restriction by
trying to first evict the offending alias from the cache. If this fails, it
still returns an error (EBUSY).
A rarer situation is if an mkdir races with an indenpendent lookup, which
finds the newly created directory already moved. In this situation the mkdir
should return success, but that would be incorrect, since the dentry cannot be
instantiated, so return EBUSY.
Previously checking for a directory alias and instantiation of the dentry
weren't done atomically in lookup/mkdir, hence two such calls racing with each
other could create aliased directories. To prevent this introduce a new
per-connection mutex: fuse_conn->inst_mutex, which is taken for instantiations
with a directory inode.

Fuse didn't always call i_size_write() with i_mutex held which caused rare
hangs on SMP/32bit. This bug has been present since fuse-2.2, well before

The simplest solution is to protect i_size_write() with the per-connection
spinlock. Using i_mutex for this purpose would require some restructuring of
the code and I'm not even sure it's always safe to acquire i_mutex in all
places i_size needs to be set.
Since most of vmtruncate is already duplicated for other reasons, duplicate
the remaining part as well, making all i_size_write() calls internal to fuse.
Using i_size_write() was unnecessary in fuse_init_inode(), since this function
is only called on a newly created locked inode.

[PATCH] knfsd: add nfs-export support to tmpfs
We need to encode a decode the 'file' part of a handle. We simply use the
inode number and generation number to construct the filehandle.
The generation number is the time when the file was created. As inode numbers
cycle through the full 32 bits before being reused, there is no real chance of
the same inum being allocated to different files in the same second so this is
suitably unique. Using time-of-day rather than e.g. jiffies makes it less
likely that the same filehandle can be created after a reboot.
In order to be able to decode a filehandle we need to be able to lookup by
inum, which means that the inode needs to be added to the inode hash table
(tmpfs doesn't currently hash inodes as there is never a need to lookup by
inum). To avoid overhead when not exporting, we only hash an inode when it is
first exported. This requires a lock to ensure it isn't hashed twice.
This code is separate from the patch posted in June06 from Atal Shargorodsky
which provided the same functionality, but does borrow slightly from it.
Locking comment: Most filesystems that hash their inodes do so at the point
where the 'struct inode' is initialised, and that has suitable locking
(I_NEW). Here in shmem, we are hashing the inode later, the first time we
need an NFS file handle for it. We no longer have I_NEW to ensure only one
thread tries to add it to the hash table.

[PATCH] posix-cpu-timers: prevent signal delivery starvation
The integer divisions in the timer accounting code can round the result
down to 0. Adding 0 is without effect and the signal delivery stops.
Clamp the division result to minimum 1 to avoid this.
Problem was reported by Seongbae Park <spark@google.com>, who provided
also an inital patch.
Roland sayeth:
I have had some more time to think about the problem, and to reproduce it
using Toyo's test case. For the record, if my understanding of the problem
is correct, this happens only in one very particular case. First, the
expiry time has to be so soon that in cputime_t units (usually 1s/HZ ticks)
it's < nthreads so the division yields zero. Second, it only affects each
thread that is so new that its CPU time accumulation is zero so now+0 is
still zero and ->it_*_expires winds up staying zero. For the VIRT and PROF
clocks when cputime_t is tick granularity (or the SCHED clock on
configurations where sched_clock's value only advances on clock ticks), this
is not hard to arrange with new threads starting up and blocking before they
accumulate a whole tick of CPU time. That's what happens in Toyo's test
case.
Note that in general it is fine for that division to round down to zero,
and set each thread's expiry time to its "now" time. The problem only
arises with thread's whose "now" value is still zero, so that now+0 winds up
0 and is interpreted as "not set" instead of ">= now". So it would be a
sufficient and more precise fix to just use max(ticks, 1) inside the loop
when setting each it_*_expires value.
But, it does no harm to round the division up to one and always advance
every thread's expiry time. If the thread didn't already fire timers for
the expiry time of "now", there is no expectation that it will do so before
the next tick anyway. So I followed Thomas's patch in lifting the max out
of the loops.
This patch also covers the reload cases, which are harder to write a test
for (and I didn't try). I've tested it with Toyo's case and it fixes that.

In general, lockdep warnings are intended to be non-fatal, so I have put in
various practical limits on internal data structure failure modes. We haven't

unwinder crashes are outside of lockdep], and that's largely due to the good
internal checks it does.
Recursion within the dependency graph is currently limited to 20, that's
probably not enough on some many-CPU boxes - this patch doubles it to 40. I
have written the lockdep functions to have as small stackframes as possible,
so 40 should be OK too. (The practical recursion limit should be somewhere
between 100 and 200 entries. If we hit that then I'll change the algorithm to
be iteration-based. Graph walking logic is so easy to program via recursion,
so i'd like to keep recursion as long as possible.)

[PATCH] ioc4: Enable build on non-SN2
The SGI PCI-RT card, based on the SGI IOC4 chip, will be made available on
Altix XE (x86_64) platforms in the near future. As such it is now a
misnomer for the IOC4 base device driver to live under drivers/sn, and
would complicate builds for non-SN2.
This patch moves the IOC4 base driver code from drivers/sn to drivers/misc,
and updates the associated Makefiles and Kconfig files to allow building on
non-SN2 configs. Due to the resulting change in link order, it is now
necessary to use late_initcall() for IOC4 subdriver initialization.

moving memory accesses out of the section of code in which the mapping is in

[POWERPC] Don't crash on cell with 2 BEs when !CONFIG_NUMA
The SPU code will crash if CONFIG_NUMA is not set and SPUs are found on
a non-0 node. This workaround will ignore those SPEs and just print an
message in the kernel log.

[PATCH] make UML compile (FC6/x86-64)
I need this patch to get a UML kernel to compile. This is with the
kernel headers in FC6 which are automatically generated from the kernel
tree. Some headers are missing but those files don't need them. At
least it appears so since the resuling kernel works fine.
Tested on x86-64.

[PATCH] Fix core files so they make sense to gdb...
It is silly to use non-static variable for writting zeroes to the file.
And more seriously, foffset in core dump file dump function was incremented
too much, so some parts of core dump were shifted by size of few phdrs and
notes down, so although gdb was able to load that file, it did not make lot
of sense - in my test case data pages were shifted down by about 900 bytes.
