Since the arrays are declared as in_urbs[N_IN_URB] and out_urbs[N_OUT_URB], both for loops go one over the end of the array. This fixes coverity id #555. Signed-off-by:

Since the visual STATIC_PSEUDOCOLOR has a read-only colormap, use logos with 16 colors only since these logos use the console palette. This has a higher likelihood that the logo will display correctly. Signed-of-by:

Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS. If both methods are unsupported, change the visual of vesafb to STATIC_PSEUDOCOLOR. Signed-off-by:

sparc32 lacks vga.h, so lots of fbdev drivers won't compile. There are no sparc32 systems with PCI slots, so it's a bit moot. The patch gives sparc32 a copy of the sparc64 vga.h. It fixes sparc32 allmodconfig without mucking up fbdev Kconfig and gives us wider compile coverage. Cc: "Antonino A. Daplas" <adaplas@pol.net> Acked-by:

It's very easy for the server to DOS itself by just giving out too many delegations. For now we just solve the problem with a dumb hard limit. Eventually we'll want a smarter policy. Signed-off-by:

We should be shutting down rpciod for the callback channel when we shut down the server. Also note that we do rpciod_up() and create the callback client *before* setting cb_set--the cb_set only determines whether the initial null was succesful. So cb_set is not a reliable determiner of whether we need to clean up, only cb_client is. Signed-off-by:

We need to make sure the laundromat work doesn't reschedule itself just when we try to cancel it. Also, we shouldn't be waiting for it to finish running while holding the state lock, as that's a potential deadlock. Signed-off-by:

Every caller of svc_take_page ignores its return value and assumes it succeeded. So just WARN() instead of returning an ignored error. This would have saved some time debugging a recent nfsd4 problem. If there are still failure cases here, then the result is probably that we overwrite an earlier part of the reply while xdr-encoding. While the corrupted reply is a nasty bug, it would be worse to panic here and create the possibility of a remote DOS; hence WARN() instead of BUG(). Signed-off-by:

We're using svc_take_page here to get another page for the tail in case one wasn't already allocated. But there isn't always guaranteed to be another page available. Also fix a typo that made us check the tail buffer for space when we meant to be checking the head buffer. Signed-off-by:

In v4 we grab an extra page just for the padding of returned data. The formula that the rpc server uses to allocate pages for the response doesn't take into account this extra page. Instead of adjusting those formulae, we adopt the same solution as v2 and v3, and put the "tail" data in the same page as the "head" data. Signed-off-by:

Since nfsd_setuser() is already called from any operation that uses the current filehandle (because it's called from fh_verify), there's no reason to call it from putrootfh. Signed-off-by:

In addition to setting the processes filesystem id's, nfsd_setuser also modifies the value of the rq_cred which stores the id's that originally came from the rpc call, for example to reflect root squashing. There's no real reason to do that--the only case where rqstp->rq_cred is actually used later on is in the NFSv4 SETCLIENTID/SETCLIENTID_CONFIRM operations, and there the results are the opposite of what we want--those two operations don't deal with the filesystem at all, they only record the credentials used with the rpc call for later reference (so that we may require the same credentials be used on later operations), and the credentials shouldn't vary just because there was or wasn't a previous operation in the compound that referred to some export This fixes a bug which caused mounts from Solaris clients to fail.

Export a directory that does not exist: exportfs -orw,fsid=0,insecure,no_subtree_check client:/home/NFS4 Try to mount from client with nfs4. Mount hangs (I'm not sure why - that's another issue). While client is hung, back on server mkdir /home/NFS4 The server panics in dput. I traced the problem back to svc_export_parse() calling path_release() even though path_lookup() failed (it happens to fill in the nameidata structure with a negative dentry - so the test after out: succeeds). After patching, an recreating the problem, the client mount still takes some time before finally exiting with a message "couldn't read superblock". Here is a simple patch to resolve this issue: Signed-off-by:

We should be using the length from the second vfs_getxattr, in case it changed. (Note: there's still a small race here; we could end up returning -ENOMEM if the length increased between the first and second call. I don't know whether it's worth spending a lot of effort to fix that.) This makes XFS ACLs usable on NFS exports, which they currently aren't, since XFS appears to be returning a too-large value for vfs_getxattr() when it's passed a NULL buffer. So there's probably an XFS bug here too, though since getxattr with a NULL buffer is usually used to decide how much memory to allocate, it may be a fairly harmless bug in most cases. Signed-off-by:

We're returning -1 in a few places in the NFSv4<->POSIX acl translation code where we could return a reasonable error. Also allows some minor simplification elsewhere. Signed-off-by:

this fixes coverity id #3. Coverity detected dead code, since the == -1 comparison only returns 0 or 1 to error. Therefore the if ( error < 0 ) statement was always false. Seems that this was an if( error = nfs4... ) statement some time ago, which got broken during cleanup. Signed-off-by:

Use the fl_lmops field to identify which locks are ours, instead of trying to look them up in our private hash. This is safer and more efficient. Earlier versions of this patch used a lock flag instead, but Trond pointed out that adding a new flag for each lock manager wasn't going to scale well, and suggested this approach instead; a separate patch converts lockd to using fl_lmops in the same way. In the NFSv4 case this looks like a bit of a hack, since the NFSv4 server isn't currently actually defining a lock_manager_operations struct, so we end up defining one *just* to serve as a cookie to identify our locks. But it works, and we actually do expect to start using the lock_manager_operations at some point anyway. Signed-off-by:

NFSd makes sure there is enough space to hold the maximum possible reply before accepting a request. The units for this maximum is (4byte) words. However in three places, particularly for read request, the number given is a number of bytes. This means too much space is reserved which is slightly wasteful. This is the sort of patch that could uncover a deeper bug, and it is not critical, so it would be best for it to spend a while in -mm before going in to mainline.
