2011-07-23nfsd: don't break lease on CLAIM_DELEGATE_CURCasey Bodley
CLAIM_DELEGATE_CUR is used in response to a broken lease; allowing it to break the lease and return EAGAIN leaves the client unable to make progress in returning the delegation nfs4_get_vfs_file() now takes struct nfsd4_open for access to the claim type, and calls nfsd_open() with NFSD_MAY_NOT_BREAK_LEASE when claim type is CLAIM_DELEGATE_CUR Signed-off-by: Casey Bodley <cbodley@citi.umich.edu> Cc: stable@kernel.org Signed-off-by: J.

2011-07-21locks: rename lock-manager opsJ. Bruce Fields
Both the filesystem and the lock manager can associate operations with a lock. Confusingly, one of them (fl_release_private) actually has the same name in both operation structures. It would save some confusion to give the lock-manager ops different names. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2011-07-18nfsd: turn on reply cache for NFSv4J. Bruce Fields
It's sort of ridiculous that we've never had a working reply cache for NFSv4. On the other hand, we may still not: our current reply cache is likely not very good, especially in the TCP case (which is the only case that matters for v4). What we really need here is some serious testing. Anyway, here's a start. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2011-07-15nfsd41: Deny new lock before RECLAIM_COMPLETE doneMi Jinlong
Before nfs41 client's RECLAIM_COMPLETE done, nfs server should deny any new locks or opens. rfc5661: " Whenever a client establishes a new client ID and before it does the first non-reclaim operation that obtains a lock, it MUST send a RECLAIM_COMPLETE with rca_one_fs set to FALSE, even if there are no locks to reclaim. If non-reclaim locking operations are done before the RECLAIM_COMPLETE, an NFS4ERR_GRACE error will be returned. " Signed-off-by: Mi Jinlong <mijinlong@cn.fujitsu.com> Signed-off-by: J.

2011-07-15nfsd41: error out when client sets maxreq_sz or maxresp_sz too smallMi Jinlong
According to RFC5661, 18.36.3, "if the client selects a value for ca_maxresponsesize such that a replier on a channel could never send a response,the server SHOULD return NFS4ERR_TOOSMALL in the CREATE_SESSION reply." So, error out when the client sets a maxreq_sz less than the minimum possible SEQUENCE request size, or sets a maxresp_sz less than the minimum possible SEQUENCE reply size.

2011-07-15nfsd4: fix file leak on open_downgradeJ. Bruce Fields
Stateid's hold a read reference for a read open, a write reference for a write open, and an additional one of each for each read+write open. The latter wasn't getting put on a downgrade, so something like: open RW open R downgrade to R was resulting in a file leak. Also fix an imbalance in an error path.

2011-07-15nfsd: Remove deprecated nfsctl system call and related code.NeilBrown
As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code. These should be cleaned out too, probably in the next merge window. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
2011-07-15NFSD: allow OP_DESTROY_CLIENTID to be only op in COMPOUNDBenny Halevy
DESTROY_CLIENTID MAY be preceded with a SEQUENCE operation as long as the client ID derived from the session ID of SEQUENCE is not the same as the client ID to be destroyed. If the client IDs are the same, then the server MUST return NFS4ERR_CLIENTID_BUSY. (that's not implemented yet) If DESTROY_CLIENTID is not prefixed by SEQUENCE, it MUST be the only operation in the COMPOUND request (otherwise, the server MUST return NFS4ERR_NOT_ONLY_OP). This fixes the error return; before, we returned NFS4ERR_OP_NOT_IN_SESSION; after this patch, we return NFS4ERR_NOTSUPP. Signed-off-by: Benny Halevy <benny@tonian.com> Signed-off-by: J.

2011-06-06nfsd: fix dependency of nfsd on auth_rpcgssJ. Bruce Fields
Commit b0b0c0a26e84 "nfsd: add proc file listing kernel's gss_krb5 enctypes" added an nunnecessary dependency of nfsd on the auth_rpcgss module. It's a little ad hoc, but since the only piece of information nfsd needs from rpcsec_gss_krb5 is a single static string, one solution is just to share it with an include file.

2011-04-30nfsd4: fix wrongsec handling for PUTFH + op casesJ. Bruce Fields
When PUTFH is followed by an operation that uses the filehandle, and when the current client is using a security flavor that is inconsistent with the given filehandle, we have a choice: we can return WRONGSEC either when the current filehandle is set using the PUTFH, or when the filehandle is first used by the following operation. Follow the recommendations of RFC 5661 in making this choice. (Our current behavior prevented the client from doing security negotiation by returning WRONGSEC on PUTFH+SECINFO_NO_NAME.)

2011-04-20Open with O_CREAT flag set fails to open existing files on non writable ↵Sachin Prabhu
directories An open on a NFS4 share using the O_CREAT flag on an existing file for which we have permissions to open but contained in a directory with no write permissions will fail with EACCES. A tcpdump shows that the client had set the open mode to UNCHECKED which indicates that the file should be created if it doesn't exist and encountering an existing flag is not an error. Since in this case the file exists and can be opened by the user, the NFS server is wrong in attempting to check create permissions on the parent directory. The patch adds a conditional statement to check for create permissions only if the file doesn't exist. Signed-off-by: Sachin S. Prabhu <sprabhu@redhat.com> Signed-off-by: J.

2011-03-25nfsd: fix auth_domain reference leak on nlm operationsJ. Bruce Fields
This was noticed by users who performed more than 2^32 lock operations and hence made this counter overflow (eventually leading to use-after-free's). Setting rq_client to NULL here means that it won't later get auth_domain_put() when it should be. Appears to have been introduced in 2.5.42 by "[PATCH] kNFSd: Move auth domain lookup into svcauth" which moved most of the rq_client handling to common svcauth code, but left behind this one line.

2011-03-16nfs41: make sure nfs server return right ca_maxresponsesize_cachedMi Jinlong
According to rfc5661, ca_maxresponsesize_cached: Like ca_maxresponsesize, but the maximum size of a reply that will be stored in the reply cache (Section 2.10.6.1). For each channel, the server MAY decrease this value, but MUST NOT increase it. the latest kernel(2.6.38-rc8) may increase the value for ignoring request's ca_maxresponsesize_cached value. We should not ignore it. Signed-off-by: Mi Jinlong <mijinlong@cn.fujitsu.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
