Check minorversion once before decoding any operation and reject with nfserr_minor_vers_mismatch if != 0 (this still happens in nfsd4_proc_compound). In this case return a zero length resultdata array as required by RFC3530. minorversion 1 processing will have its own vector of decoders.

knfsd currently uses 2 signal masks when processing requests. A "loose" mask (SHUTDOWN_SIGS) that it uses when receiving network requests, and then a more "strict" mask (ALLOWED_SIGS, which is just SIGKILL) that it allows when doing the actual operation on the local storage. This is apparently unnecessarily complicated. The underlying filesystem should be able to sanely handle a signal in the middle of an operation. This patch removes the signal mask handling from knfsd altogether. When knfsd is started as a kthread, all signals are ignored. It then allows all of the signals in SHUTDOWN_SIGS. There's no need to set the mask as well. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NJ. Bruce Fields <bfields@citi.umich.edu>

Thanks to Frank Van Maarseveen for the original problem report: "A privileged process on an NFS client which drops privileges after using them to change the current working directory, will experience incorrect EACCES after an NFS server reboot. This problem can also occur after memory pressure on the server, particularly when the client side is quiet for some time." This occurs because the filehandle points to a directory whose parents are no longer in the dentry cache, and we're attempting to reconnect the directory to its parents without adequate permissions to perform lookups in the parent directories. We can therefore fix the problem by acquiring the necessary capabilities before attempting the reconnection. We do this only in the no_subtree_check case, since the documented behavior of the subtree_check export option requires the server to check that the user has lookup permissions on all parents. The subtree_check case still has a problem, since reconnect_path() unnecessarily requires both read and lookup permissions on all parent directories. However, a fix in that case would be more delicate, and use of subtree_check is already discouraged for other reasons.

cleanup: Document token header size with a #define instead of open-coding it. Don't needlessly increment "ptr" past the beginning of the header which makes the values passed to functions more understandable and eliminates the need for extra "krb5_hdr" pointer. Clean up some intersecting white-space issues flagged by checkpatch.pl. This leaves the checksum length hard-coded at 8 for DES. A later patch cleans that up.

OCFS2 can return -ERESTARTSYS from write requests (and possibly elsewhere) if there is a signal pending. If nfsd is shutdown (by sending a signal to each thread) while there is still an IO load from the client, each thread could handle one last request with a signal pending. This can result in -ERESTARTSYS which is not understood by nfserrno() and so is reflected back to the client as nfserr_io aka -EIO. This is wrong. Instead, interpret ERESTARTSYS to mean "try again later" by returning nfserr_jukebox. The client will resend and - if the server is restarted - the write will (hopefully) be successful and everyone will be happy. The symptom that I narrowed down to this was: copy a large file via NFS to an OCFS2 filesystem, and restart the nfs server during the copy. The 'cp' might get an -EIO, and the file will be corrupted - presumably holes in the middle where writes appeared to fail. Signed-off-by: NNeil Brown <neilb@suse.de> Signed-off-by: NJ.

This patch is rather large, but I couldn't figure out a way to break it up that would remain bisectable. It does several things: - change svc_thread_fn typedef to better match what kthread_create expects - change svc_pool_map_set_cpumask to be more kthread friendly. Make it take a task arg and and get rid of the "oldmask" - have svc_set_num_threads call kthread_create directly - eliminate __svc_create_thread Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NJ.

Several of the nfsd filesystem interfaces allow changes to parameters that don't have any effect on a running nfsd service. They are only ever checked when nfsd is started. This patch fixes it so that changes to those procfiles return -EBUSY if nfsd is already running to make it clear that changes on the fly don't work. The patch should also close some relatively harmless races between changing the info in those interfaces and starting nfsd, since these variables are being moved under the protection of the nfsd_mutex. Finally, the nfsv4recoverydir file always returns -EINVAL if read. This patch fixes it to return the recoverydir path as expected. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NJ.

This removes the BKL from the RPC service creation codepath. The BKL really isn't adequate for this job since some of this info needs protection across sleeps. Also, add some comments to try and clarify how the locking should work and to make it clear that the BKL isn't necessary as long as there is adequate locking between tasks when touching the svc_serv fields.

WRITEMEM zeroes the last word in the destination buffer for padding purposes, but this must not be done if no bytes are to be copied, as it would result in zeroing of the word right before the array. The current implementation works since it's always called with non zero nbytes or it follows an encoding of the string (or opaque) length which, if equal to zero, can be overwritten with zero. Nevertheless, it seems safer to check for this case. Signed-off-by: NBenny Halevy <bhalevy@panasas.com> Signed-off-by: NJ. Bruce Fields <bfields@citi.umich.edu>
