| * nfsd: don't fail unchecked creates of non-special filesJ. Bruce Fields2012-04-112-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow a v3 unchecked open of a non-regular file succeed as if it were a lookup; typically a client in such a case will want to fall back on a local open, so succeeding and giving it the filehandle is more useful than failing with nfserr_exist, which makes it appear that nothing at all exists by that name. Similarly for v4, on an open-create, return the same errors we would on an attempt to open a non-regular file, instead of returning nfserr_exist. This fixes a problem found doing a v4 open of a symlink with O_RDONLY|O_CREAT, which resulted in the current client returning EEXIST. Thanks also to Trond for analysis.

Plus miscellaneous bugfixes and cleanup. Thanks to everyone! There are also some delegation fixes waiting on vfs review that I suppose will have to wait for 3.5. With that done I think we'll finally turn off the "EXPERIMENTAL" dependency for v4 (though that's mostly symbolic as it's been on by default in distro's for a while). And the list of 4.1 todo's should be achievable for 3.5 as well: http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues though we may still want a bit more experience with it before turning it on by default. * 'for-3.4' of git://linux-nfs.org/~bfields/linux: (55 commits) nfsd: only register cld pipe notifier when CONFIG_NFSD_V4 is enabled nfsd4: use auth_unix unconditionally on backchannel nfsd: fix NULL pointer dereference in cld_pipe_downcall nfsd4: memory corruption in numeric_name_to_id() sunrpc: skip portmap calls on sessions backchannel nfsd4: allow numeric idmapping nfsd: don't allow legacy client tracker init for anything but init_net nfsd: add notifier to handle mount/unmount of rpc_pipefs sb nfsd: add the infrastructure to handle the cld upcall nfsd: add a header describing upcall to nfsdcld nfsd: add a per-net-namespace struct for nfsd sunrpc: create nfsd dir in rpc_pipefs nfsd: add nfsd4_client_tracking_ops struct and a way to set it nfsd: convert nfs4_client->cl_cb_flags to a generic flags field NFSD: Fix nfs4_verifier memory alignment NFSD: Fix warnings when NFSD_DEBUG is not defined nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes) nfsd: rename 'int access' to 'int may_flags' in nfsd_open() ext4: return 32/64-bit dir name hash according to usage type fs: add new FMODE flags: FMODE_32bithash and FMODE_64bithash ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mimic the client side by providing a module parameter that turns off idmapping in the auth_sys case, for backwards compatibility with NFSv2 and NFSv3. Unlike in the client case, we don't have any way to negotiate, since the client can return an error to us if it doesn't like the id that we return to it in (for example) a getattr call. However, it has always been possible for servers to return numeric id's, and as far as we're aware clients have always been able to handle them. Also, in the auth_sys case clients already need to have numeric id's the same between client and server. Therefore we believe it's safe to default this to on; but the module parameter is available to return to previous behavior if this proves to be a problem in some unexpected setup. Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...and add a mechanism for switching between the "legacy" tracker and the new one. The decision is made by looking to see whether the v4recoverydir exists. If it does, then the legacy client tracker is used. If it's not, then the kernel will create a "cld" pipe in rpc_pipefs. That pipe is used to talk to a daemon for handling the upcall. Most of the data structures for the new client tracker are handled on a per-namespace basis, so this upcall should be essentially ready for containerization. For now however, nfsd just starts it by calling the initialization and exit functions for init_net. I'm making the assumption that at some point in the future we'll be able to determine the net namespace from the nfs4_client. Until then, this patch hardcodes init_net in those places. I've sprinkled some "FIXME" comments around that code to attempt to make it clear where we'll need to fix that up later. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | Eventually, we'll need this when nfsd gets containerized fully. For now, create a struct on a per-net-namespace basis that will just hold a pointer to the cld_net structure. That struct will hold all of the per-net data that we need for the cld tracker.

| * nfsd: add nfsd4_client_tracking_ops struct and a way to set itJeff Layton2012-03-263-58/+156
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Abstract out the mechanism that we use to track clients into a set of client name tracking functions. This gives us a mechanism to plug in a new set of client tracking functions without disturbing the callers. It also gives us a way to decide on what tracking scheme to use at runtime. For now, this just looks like pointless abstraction, but later we'll add a new alternate scheme for tracking clients on stable storage. Note too that this patch anticipates the eventual containerization of this code by passing in struct net pointers in places. No attempt is made to containerize the legacy client tracker however.

| * nfsd: convert nfs4_client->cl_cb_flags to a generic flags fieldJeff Layton2012-03-265-33/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We'll need a way to flag the nfs4_client as already being recorded on stable storage so that we don't continually upcall. Currently, that's recorded in the cl_firststate field of the client struct. Using an entire u32 to store a flag is rather wasteful though. The cl_cb_flags field is only using 2 bits right now, so repurpose that to a generic flags field. Rename NFSD4_CLIENT_KILL to NFSD4_CLIENT_CB_KILL to make it evident that it's part of the callback flags. Add a mask that we can use for existing checks that look to see whether any flags are set, so that the new flags don't interfere. Convert all references to cl_firstate to the NFSD4_CLIENT_STABLE flag, and add a new NFSD4_CLIENT_RECLAIM_COMPLETE flag. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.

| * | NFSD: Fix nfs4_verifier memory alignmentChuck Lever2012-03-204-28/+31

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. We can fix most of this by using a __be32 array to generate the verifier's contents and then byte-copying it into the verifier field. However, there is one spot where there is a backwards compatibility constraint: the do_nfsd_create() call expects a verifier which is 32-bit aligned. Fix this spot by forcing the alignment of the create verifier in the nfsd4_open args structure. 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: J. Bruce Fields <bfields@redhat.com>
