* NFSv4.1 handle DS stateid errorsAndy Adamson2012-03-07
| | | | | | | | | | Handle DS READ and WRITE stateid errors by recovering the stateid on the MDS. NFS4ERR_OLD_STATEID is ignored as the client always sends a state sequenceid of zero for DS READ and WRITE stateids.

* NFS: Fix nfs4_verifier memory alignmentChuck Lever2012-03-06
| | | | | | | | | | | | | | | | | | | | | | | Clean up due to code review. The nfs4_verifier's data field is not guaranteed to be u32-aligned. Casting an array of chars to a u32 * is considered generally hazardous. Fix this by using a __be32 array to generate a verifier's contents, and then byte-copy the contents into the verifier field. The contents of a verifier, for all intents and purposes, are opaque bytes. Only local code that generates a verifier need know the actual content and format. Everyone else compares the full byte array for exact equality. Also, sizeof(nfs4_verifer) is the size of the in-core verifier data structure, but NFS4_VERIFIER_SIZE is the number of octets in an XDR'd verifier. The two are not interchangeable, even if they happen to have the same value. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4.1: Fix matching of the stateids when returning a delegationTrond Myklebust2012-03-06
| | | | | | | | | | | | nfs41_validate_delegation_stateid is broken if we supply a stateid with a non-zero sequence id. Instead of trying to match the sequence id, the function assumes that we always want to error. While this is true for a delegation callback, it is not true in general. Also fix a typo in nfs4_callback_recall. Reported-by: Andy Adamson <andros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Properly handle the case where the delegation is revokedTrond Myklebust2012-03-06
| | | | | | | | | | | | | | | | If we know that the delegation stateid is bad or revoked, we need to remove that delegation as soon as possible, and then mark all the stateids that relied on that delegation for recovery. We cannot use the delegation as part of the recovery process. Also note that NFSv4.1 uses a different error code (NFS4ERR_DELEG_REVOKED) to indicate that the delegation was revoked. Finally, ensure that setlk() and setattr() can both recover safely from a revoked delegation. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: stable@vger.kernel.org

| * NFSv4.1: Fix a NFSv4.1 session initialisation regressionTrond Myklebust2012-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit aacd553 (NFSv4.1: cleanup init and reset of session slot tables) introduces a regression in the session initialisation code. New tables now find their sequence ids initialised to 0, rather than the mandated value of 1 (see RFC5661). Fix the problem by merging nfs4_reset_slot_table() and nfs4_init_slot_table(). Since the tbl->max_slots is initialised to 0, the test in nfs4_reset_slot_table for max_reqs != tbl->max_slots will automatically pass for an empty table.

| * NFSv4: Fix an Oops in the NFSv4 getacl codeTrond Myklebust2012-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bf118a342f10dafe44b14451a1392c3254629a1f (NFSv4: include bitmap in nfsv4 get acl data) introduces the 'acl_scratch' page for the case where we may need to decode multi-page data. However it fails to take into account the fact that the variable may be NULL (for the case where we're not doing multi-page decode), and it also attaches it to the encoding xdr_stream rather than the decoding one. The immediate result is an Oops in nfs4_xdr_enc_getacl due to the call to page_address() with a NULL page pointer.

| | * | ALSA: hda - Allow analog low-current mode when dynamic power-control is onTakashi Iwai2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VIA codecs have several different power-saving features, and one of them is the analog low-current mode. But it turned out that the ALC mode causes pop-noises at each on/off time on some machines. As a quick workaround, disable the ALC when another power-saving feature, the dynamic pin power-control, is turned off, too, since the dynamic power-control is already exposed as a mixer enum element so that user can turn it on/off freely.

Moreover, it's required even when the pin is being used as the output. Thus, writing a fixed value doesn't work always. This patch applies the VREF-fix for all ASUS laptops with ALC861/660 in a fixup function that checks the current value and turns on only the VREF value no matter whether input or output direction is set. The automute function is modified as well to keep the pin VREF upon muting/unmuting via pin-control; otherwise the pin VREF is reset at plugging/unplugging a jack.
