* uss/gluster: generate gfid for snapshot files from snapname and gfidvmallika2016-03-233-33/+122

* uss : handle `buf` variable properly in svs_glfs_readdir()Jiffin Tony Thottan2015-09-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | The svs_glfs_readdir() is a generic function which is called from svs_readdir() and svs_readdirp().

* libgfapi: adding 'follow' flag to glfs_h_lookupat()Jiffin Tony Thottan2015-08-251-1/+1

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The @owner argument tells RPC layer the xlator that owns the connection and to which xlator THIS needs be set during network notifications like CONNECT and DISCONNECT. Code paths that originate from the head of a (volume) graph and use STACK_WIND ensure that the RPC local endpoint has the right xlator saved in the frame of the call (callback pair). This guarantees that the callback is executed in the right xlator context. The client handshake process which includes fetching of brick ports from glusterd, setting lk-version on the brick for the session, don't have the correct xlator set in their frames. The problem lies with RPC notifications. It doesn't have the provision to set THIS with the xlator that is registered with the corresponding RPC programs. e.g, RPC_CLNT_CONNECT event received by protocol/client doesn't have THIS set to its xlator. This implies, call(-callbacks) originating from this thread don't have the right xlator set too. The fix would be to save the xlator registered with the RPC connection during rpc_clnt_new. e.g, protocol/client's xlator would be saved with the RPC connection that it 'owns'. RPC notifications such as CONNECT, DISCONNECT, etc inherit THIS from the RPC connection's xlator.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-042-38/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | correct before doing any fop The following operations might lead to problems: * Create a file on the glusterfs mount point * Create a snapshot (say "snap1") * Access the contents of the snapshot * Delete the file from the mount point * Delete the snapshot "snap1" * Create a new snapshot "snap1" Now accessing the new snapshot "snap1" gives problems. Because the inode and dentry created for snap1 would not be deleted upon the deletion of the snapshot (as deletion of snapshot is a gluster cli operation, not a fop). So next time upon creation of a new snap with same name, the previous inode and dentry itself will be used. But the inode context contains old information about the glfs_t instance and the handle in the gfapi world. Directly accessing them without proper check leads to ENOTCONN errors. Thus the glfs_t instance should be checked before accessing. If its wrong, then right instance should be obtained by doing the lookup.

| | | | | | | | | | | | | | | | | | | | | | | * Now that NFS server does inode linking in readdirp, it can resolve the gfid (i.e. find the right inode from its inode table) present in the filehandle sent by the NFS client on which a fop came. So instead of sending the lookup on that entry, it directly sends the fop. But snapview-server does not get the handle for the entries in readdirp (because doing a lookup on each entry via gfapi would be costly. So it waits till a lookup is done on that inode, to get the handle and the fs instance and fill it in the inode context). So when NFS resoves the gfid and directly sends the fop, snapview-server will not be able to perform the fop as the inode contet would not contain the fs instance and the handle. So fops should check for the handle before doing gfapi calls. If the handle and fs instance are not present in the inode context they should get them by doing an explicit lookup on the entry.

* make snapview-server more compatible with NFS serverRaghavendra Bhat2014-07-161-78/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * There was no handle based API for listxattr. With this change, glfs_h_getxattrs also handles the listxattr functionality by checking whether the name is NULL or not (like posix). But all the gfapi functions for listxattr (glfs_h_getxattrs AND glfs_listxattr AND glfs_flistxattr) returns the names of the xattrs in a buffer provided by the caller. But snapview-server has to return the list of xattrs in a dict itself (similar to posix xlator). But the buffer just contains the names of the xattrs. So for each xattr, a zero byte value is set (i.e. "") into the dict and sent back. Translators which do xattr caching (as of now md-cache which caches selinux and acl related xattrs) should not cache those xattrs whose value is a zero byte data (""). So made changes in md-cache to ignore zero byte values. * NFS server was not linking the inodes to inode table in readdirp. This was leading to applications getting errors. The below set of operations would lead to applications getting error 1) ls -l in one of the snaopshots (snapview-server would generate gfids for each entry on the fly and link the inodes associated with those entries) 2) NFS server upon getting readdirp reply would not link the inodes of the entries. But it used to generate filehandles for each entry and associate the gfid of that entry with the filehandle and send it as part of the reply to nfs client. 3) NFS client would send the filehandle of one of those entries when some activity is done on it. 4) NFS server would not be able to find the inode for the gfid present in the filehandle (as the inode was not linked) and would go for hard resolution by sending a lookup on the gfid by creating a new inode. 5) snapview-client will not able to identify whether the inode is a real inode existing in the main volume or a virtual inode existing in the snapshots as there would not be any inode context. 6) Since the gfid upon which lookup is sent is a virtual gfid which is not present in the disk, lookup would fail and the application would get an error. To handle above situation, now nfs server also does inode linking in readdirp.

| | | | | | | | | | | | | | | | | * dirent structure (struct dirent) in NetBSD does not contain the offset member. Direct access of offset from struct dirent (used here to copy its contents to gf_dirent_t structure after making readdir call) causes glusterfs build failures on NetBSD. So like posix does, use telldir api to get the offset of the dentry (in this case glfs_telldir).
