Trivial renaming patch: I can never remember, while looking at various lists relating the nfsd4 state structures, which are the "heads" and which are items on other lists, or which structures are actually on the various lists. The following convention helps me: given structures foo and bar, with foo containing the head of a list of bars, use "bars" for the name of the head of the list contained in the struct foo, and use "per_foo" for the entries in the struct bars. Go ahead and do this for struct nfs4_file. Signed-off-by:

Allocate stateid's from a slab cache. Signed-off-by:
-
NeilBrown authored
The structures the server uses to keep track of various pieces of nfsv4 state (open files, outstanding delegations, etc.) are likely to be allocated and deallocated frequently and seem reasonable candidates for slab caches. While we're at it, the slab code keeps statistics that help catch leaks and such, so we may as well take this chance to eliminate some debugging counters that we've been keeping ourselves. Start with the struct nfs4_file. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Add OPEN claim type NFS4_OPEN_CLAIM_DELEGATE_CUR to nfsd4_open(). A delegation stateid and a name are provided. OPEN with O_CREAT is not legal with this claim type; otherwise, use the NFS4_OPEN_CLAIM_NULL code path to lookup the filename to be opened. Signed-off-by:

State logic for OPEN with claim type CLAIM_DELEGATE_CUR, which the NFSv4 client uses to report local OPENs on a delegated file back to the NFSv4 server. nfs4_check_deleg() performs input delegation stateid lookup and sanity check. Signed-off-by:

We don't really need to be doing a separate open for every stateid. And in the case of an open from a client that already has a delegation on a file, it unnecessarily results in a delegation recall. Signed-off-by:

The below patch passes samples from anonymous regions to userspace instead of just dropping them. This provides the support needed for reporting anonymous-region code samples (today: basic accumulated results; later: Java and other dynamically compiled code). As this changes the format, an upgrade to the just-released 0.9 release of the userspace tools is required. This patch is based upon an earlier one by Will Cohen <wcohen@redhat.com> Signed-off-by:

tuner-core.c, tuner.h: - tuner-core changed to support multiple I2C devices used on some adapters; - Kconfig now has an option (CONFIG_TUNER_MULTI_I2C) to enable this new behavor; - By default, even enabling CONFIG_TUNER_MULTI_I2C, tuner-core emulates the old behavor, using first I2C device for both FM and TV; - There is a new i2c command (TUNER_SET_ADDR) to allow tuner clients to select I2C address for FM or TV tuner; - Tuner I2C dettach now generates a warning on syslog if failed. tuner-simple.c: - TVision TVF-8531MF and TVF-5533 MF tuner included. It uses, by default, I2C on 0xC2 address for TV and on 0xC0 for Radio. Both TV and FM Radio mode are working. Signed-off-by:

This patch updates all the device attribute callbacks that weren't updated with the new parameter, I guess because they weren't in Greg's tree (including drivers/pcmcia/ds.c). Without the patch these callbacks are probably broken (and generate a warning along the lines of "assignment from incompatible pointer type"). Please see http://lkml.org/lkml/2005/5/19/40 for the scripts I used to update the attributes automatically. Signed-off-by:

Since after reconsideration this is more debug output than an error (the TPM is operating correctly given the current state) I have changed the statements to dbg rather than err. Also this patch corrects a memory leak if the error path is taken in the tpm_show_pubek function. Signed-off-by:
