* nfs: Authentication performance improvementsShreyas Siravara2015-06-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When file operations are sent to the NFS server, authorized filehandles are cached using the exportid, mountid, gfid and host as the key to the cache. This meant that any file OR directory will always fail on the *first* fop to that filehandle since the cache used the gfid as part of the key to the cache. However, if an export is authorized, this effectively means that ALL subdirectories and files in the export directory are authorized per the permissions of the export. This results slow times to walking a directory structure over an NFS mount.

* nfs: allocate and return the hashkey for the auth_cache_entryNiels de Vos2015-06-091-7/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The allocation of the hashkey was never returned to the calling function. Allocating it with alloca() puts it on the stack, returning from the function makes the pointer invalid. Functions that are annotated with "inline" and call alloca(), will not always be inlined. Returning a pointer allocated with alloca() is in those cases not correct. One such confirmation was provided by GCC developer Alexandre Oliva: - http://gcc.gnu.org/ml/gcc-help/2004-04/msg00158.html It is more correct to call GF_MALLOC() and GF_FREE() for the hashkey. If this would result in preformance hit, we can always think of using alloca() again and turn make_hashkey() into a macro (yuck).

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-0410-48/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gNFS: Subdir mount does not work on UDP protoSantosh Kumar Pradhan2014-10-076-104/+376
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After enabling nfs.mount-udp, mounting a subdir on a volume over NFS fails. Because mountudpproc3_mnt_3_svc() invokes nfs3_rootfh() which internally calls mnt3_mntpath_to_export() to resolve the mount path. mnt3_mntpath_to_export() just works if the mount path requested is volume itself. It is not able to resolve, if the path is a subdir inside the volume. MOUNT over TCP uses mnt3_find_export() to resolve subdir path but UDP can't use this routine because mnt3_find_export() needs the req data (of type rpcsvc_request_t) and it's available only for TCP version of RPC. FIX: (1) Use syncop_lookup() framework to resolve the MOUNT PATH by breaking it into components and resolve component-by-component. i.e. glfs_resolve_at () API from libgfapi shared object. (2) If MOUNT PATH is subdir, then make sure subdir export is not disabled. (3) Add auth mechanism to respect nfs.rpc-auth-allow/reject and subdir auth i.e. nfs.export-dir (4) Enhanced error handling for MOUNT over UDP Change-Id: I42ee69415d064b98af4f49773026562824f684d1 BUG: 1118311 Signed-off-by: Santosh Kumar Pradhan <spradhan@redhat.com> Reviewed-on: http://review.gluster.org/8346 Reviewed-by: soumya k <skoduri@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* build: make GLUSTERD_WORKDIR rely on localstatedirHarshavardhana2014-08-072-5/+3
| | | | | | | | | | | | | | | | | | | | | | - Break-way from '/var/lib/glusterd' hard-coded previously, instead rely on 'configure' value from 'localstatedir' - Provide 's/lib/db' as default working directory for gluster management daemon for BSD and Darwin based installations - loff_t is really off_t on Darwin - fix-off the warnings generated by clang on FreeBSD/Darwin - Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all platforms. - Define proper environment for running tests, define correct PATH and LD_LIBRARY_PATH when running tests, so that the desired version of glusterfs is used, regardless where it is installed.

* make snapview-server more compatible with NFS serverRaghavendra Bhat2014-07-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* nfs: prevent assertion error with MOUNT over UDPNiels de Vos2014-07-072-1/+10
| | | | | | | | | | | | | | | | | | | | | | | The MOUNT service over UDP runs in a separate thread. This thread does not have the correct *THIS xlator set. *THIS points to the global (base) xlator structure, but GF_CALLOC() requires it to be the NFS-xlator so that assertions can get validated correctly. This is solved by passing the NFS-xlator to the pthread function, and setting the *THIS pointer explicitly in the new thread. It seems that on occasion (needs further investigation) MOUNT over UDP does not unregister itself. There can also be issues when the kernel NLM implementation has been registered at portmap/rpcbind, so adding some unregister procedures in the cleanup of the test-cases.

* gNFS: Fix multi-homed m/c issue in NFS subdir authSantosh Kumar Pradhan2014-06-252-90/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | NFS subdir authentication doesn't correctly handle multi-homed (host with multiple NIC having multiple IP addr) OR multi-protocol (IPv4 and IPv6) network addresses. When user/admin sets HOSTNAME in gluster CLI for NFS subdir auth, mnt3_verify_auth() routine does not iterate over all the resolved n/w addrs returned by getaddrinfo() n/w API. Instead, it just tests with the one returned first. 1. Iterate over all the n/w addrs (linked list) returned by getaddrinfo(). 2. Move the n/w mask calculation part to mnt3_export_fill_hostspec() instead of doing it in mnt3_verify_auth() i.e. calculating for each mount request. It does not change for MOUNT req. 3. Integrate "subnet support code rpc-auth.addr.<volname>.allow" and "NFS subdir auth code" to remove code duplication.
