[PATCH] nfsd4: block metadata ops during grace period

We currently return err_grace if a user attempts a non-reclaim open during the
grace period.  But we also need to prevent renames and removes, at least, to
ensure clients have the chance to recover state on files before they are moved
or deleted.

Of course, local users could also do renames and removes during the lease
period, and there's not much we can do about that.  This at least will help
with remote users.

NeilBrown [Fri, 24 Jun 2005 05:02:58 +0000 (22:02 -0700)]
[PATCH] nfsd4: fix fh_expire_type

We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the
fh_expire_type attribute.  This is incorrect:
1. The spec actually only allows NOEXPIRE_WITH_OPEN when
   VOLATILE_ANY is also set.
2. Filehandles for open files can expire, if the file is removed
   and there is a reboot.
3. Filehandles are only volatile on rename in the nosubtree check
   case.

Unfortunately, there's no way to indicate that we only expire on remove.  So
our only choice is FH4_VOLATILE_ANY.  Although it's redundant, we also set
FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually
cause problems in practice and it seems possibly useful to give clients some
way to distinguish that case.

Fix a mispelled #define while we're at it.

It can be modified dynamically through the proc entry mentioned above.  During
a power down and enabled, the power cycle command is sent to the BMC firmware.
 If it fails either due to non-support or some error, it will retry to send

19 years ago[PATCH] Keys: Make request-key create an authorisation key
David Howells [Fri, 24 Jun 2005 05:00:56 +0000 (22:00 -0700)]
[PATCH] Keys: Make request-key create an authorisation key

The attached patch makes the following changes:

 (1) There's a new special key type called ".request_key_auth".

     This is an authorisation key for when one process requests a key and
     another process is started to construct it. This type of key cannot be
     created by the user; nor can it be requested by kernel services.

     Authorisation keys hold two references:

     (a) Each refers to a key being constructed. When the key being
       constructed is instantiated the authorisation key is revoked,
       rendering it of no further use.

     (b) The "authorising process". This is either:

       (i) the process that called request_key(), or:

       (ii) if the process that called request_key() itself had an
            authorisation key in its session keyring, then the authorising
            process referred to by that authorisation key will also be
            referred to by the new authorisation key.

 This means that the process that initiated a chain of key requests
 will authorise the lot of them, and will, by default, wind up with
 the keys obtained from them in its keyrings.

 (2) request_key() creates an authorisation key which is then passed to
     /sbin/request-key in as part of a new session keyring.

 (3) When request_key() is searching for a key to hand back to the caller, if
     it comes across an authorisation key in the session keyring of the
     calling process, it will also search the keyrings of the process
     specified therein and it will use the specified process's credentials
     (fsuid, fsgid, groups) to do that rather than the calling process's
     credentials.

     This allows a process started by /sbin/request-key to find keys belonging
     to the authorising process.

 (4) A key can be read, even if the process executing KEYCTL_READ doesn't have
     direct read or search permission if that key is contained within the
     keyrings of a process specified by an authorisation key found within the
     calling process's session keyring, and is searchable using the
     credentials of the authorising process.

     This allows a process started by /sbin/request-key to read keys belonging
     to the authorising process.

 (5) The magic KEY_SPEC_*_KEYRING key IDs when passed to KEYCTL_INSTANTIATE or
     KEYCTL_NEGATE will specify a keyring of the authorising process, rather
     than the process doing the instantiation.

 (7) request_key() is partially interruptible. If it is waiting for another

David Howells [Fri, 24 Jun 2005 05:00:49 +0000 (22:00 -0700)]
[PATCH] keys: Discard key spinlock and use RCU for key payload

The attached patch changes the key implementation in a number of ways:

 (1) It removes the spinlock from the key structure.

 (2) The key flags are now accessed using atomic bitops instead of
     write-locking the key spinlock and using C bitwise operators.

     The three instantiation flags are dealt with with the construction
     semaphore held during the request_key/instantiate/negate sequence, thus
     rendering the spinlock superfluous.

     The key flags are also now bit numbers not bit masks.

 (3) The key payload is now accessed using RCU. This permits the recursive
     keyring search algorithm to be simplified greatly since no locks need be
     taken other than the usual RCU preemption disablement. Searching now does
     not require any locks or semaphores to be held; merely that the starting
     keyring be pinned.

 (4) The keyring payload now includes an RCU head so that it can be disposed
     of by call_rcu(). This requires that the payload be copied on unlink to
     prevent introducing races in copy-down vs search-up.

 (5) The user key payload is now a structure with the data following it. It
     includes an RCU head like the keyring payload and for the same reason. It
     also contains a data length because the data length in the key may be
     changed on another CPU whilst an RCU protected read is in progress on the
     payload. This would then see the supposed RCU payload and the on-key data
     length getting out of sync.

     I'm tempted to drop the key's datalen entirely, except that it's used in
     conjunction with quota management and so is a little tricky to get rid
     of.

 (6) Update the keys documentation.

[PATCH] aio: fix do_sync_(read|write) to properly handle aio retries

When do_sync_(read|write) encounters an aio method that makes use of the
retry mechanism, they fail to correctly retry the operation.  This fixes
that by adding the appropriate sleep and retry mechanism.

19 years ago[PATCH] Bug in error recovery in fs/buffer.c::__block_prepare_write()
Anton Altaparmakov [Thu, 23 Jun 2005 07:10:21 +0000 (00:10 -0700)]
[PATCH] Bug in error recovery in fs/buffer.c::__block_prepare_write()

fs/buffer.c::__block_prepare_write() has broken error recovery.  It calls
the get_block() callback with "create = 1" and if that succeeds it
immediately clears buffer_new on the just allocated buffer (which has
buffer_new set).

The bug is that if an error occurs and get_block() returns != 0, we break
from this loop and go into recovery code.  This code has this comment:

/* Error case: */
/*
 * Zero out any newly allocated blocks to avoid exposing stale
 * data.  If BH_New is set, we know that the block was newly
 * allocated in the above loop.
 */

So the intent is obviously good in that it wants to clear just allocated
and hence not zeroed buffers.  However the code recognises allocated
buffers by checking for buffer_new being set.

Unfortunately __block_prepare_write() as discussed above already cleared
buffer_new on all allocated buffers thus no buffers will be cleared during
error recovery and old data will be leaked.

The simplest way I can see to fix this is to make the current recovery code
work by _not_ clearing buffer_new after calling get_block() in
__block_prepare_write().

We cannot safely allow buffer_new buffers to "leak out" of
__block_prepare_write(), thus we simply do a quick loop over the buffers
clearing buffer_new on each of them if it is set just before returning
"success" from __block_prepare_write().
