* Multiple files: make root gfid a static variableYaniv Kaul2019-10-141-8/+2
| | | | | | | | | | | | | In many places we use it, compare to it, etc. It could be a static variable, as it really doesn't change. I think it's better than initializing to 0 and then doing gfid[15] = 1 or other tricks. I think there are additional oppportunuties to make more variables static. This is an attempt at an easy one.

* rpc/transport: Missing a ref on dict while creating transport objectMohammed Rafi KC2019-03-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | while creating rpc_tranpsort object, we store a dictionary without taking a ref on dict but it does an unref during the cleaning of the transport object. So the rpc layer expect the caller to take a ref on the dictionary before passing dict to rpc layer. This leads to a lot of confusion across the code base and leads to ref leaks. Semantically, this is not correct. It is the rpc layer responsibility to take a ref when storing it, and free during the cleanup. I'm listing down the total issues or leaks across the code base because of this confusion. These issues are currently present in the upstream master. 1) changelog_rpc_client_init 2) quota_enforcer_init 3) rpcsvc_create_listeners : when there are two transport, like tcp,rdma. 4) quotad_aggregator_init 5) glusterd: init 6) nfs3_init_state 7) server: init 8) client:init This patch does the cleanup according to the semantics.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* nfs: use "/" as subdir for volume mountsNiels de Vos2017-08-011-17/+14
| | | | | | | | | | | | | | | | | | | | | | For cases where subdir mounting is checked, it makes it much easier to return a subdir of "/" in case no subdir is passed. This reduces the number of corner cases where permissions are checked for subdir mounts, but not for volume mounts (or the other way around). The problem was identified by WebNFS mounting a volume, which got denied after commit e3f48fa2. Handling this would require an exception for non-subdir mounts, or make non-subdir mounts equal to subdir mounts. This change takes the 2nd approach.

* nfs: add permission checking for mounting over WebNFSNiels de Vos2017-07-091-21/+39
| | | | | | | | | | | | | | | | | | | | | | | Solaris 10 uses WebNFS and not the MOUNT protocol. All permission checks for allowing/denying clients to mount are done through the MNT handlers. These handlers will not give out a filehandle to the NFS-client when mounting is denied. This prevents clients from successful mounting. However, over WebNFS a well known 'root-filehandle' is used directly with the NFSv3 protocol. When WebNFS was used, no permission checks (the "nfs.export-dir" option) were applied. Now the WebNFS mount-handler in Gluster/NFS calls the mnt3_parse_dir_exports() function that takes care of the permission checking.

* Halo Replication feature for AFR translatorKevin Vigor2017-05-021-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Halo Geo-replication is a feature which allows Gluster or NFS clients to write locally to their region (as defined by a latency "halo" or threshold if you like), and have their writes asynchronously propagate from their origin to the rest of the cluster. Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size).

Each 'groupnode' should be a single entry in the 'nfs.rpc-auth-allow' volume option. Because the value is handled as a single string, the encoding of the groupnode->gr_name fails when the value of the volume option is longer than 255 characters. In the error case, encoding the EXPORTS reply fails, and the waiting 'showmount' command will not receive a reply and times out. Splitting the allowed entries and creating a groupnode for each one prevents the too long ->gr_name. This is following the structures for the EXPORTS reply in the MOUNT protocol more correctly as well. Note that the contents of ->gr_name is expected to be server dependent.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Pradhan2014-10-071-75/+319
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* nfs: prevent assertion error with MOUNT over UDPNiels de Vos2014-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 Pradhan2014-06-251-89/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mgmt/gluster: Use fsync instead of O_SYNCPranith Kumar K2014-05-051-2/+0
| | | | | | | | | | | | | | | | | Glusterd uses O_SYNC to write to temp file then performs renames to the actual file and performs fsync on parent directory. Until this rename happens syncing writes to the file can be deferred. In this patch O_SYNC open of temp file is removed and fsync of the fd before rename is done.

* gNFS: mnt3_find_export() by pass AUTH checkSantosh Kumar Pradhan2014-01-081-14/+36
| | | | | | | | | | | | | | | | | | | | NFS subdir mount does not respect nfs.rpc-auth-reject option in the volume. If the volume is being mounted, then it would validate the AUTH by mnt3_check_client_net() but if the client is mounting a subdir, the control takes a different code path i.e. mnt3_find_export() which does not bother about the AUTH. FIX: Enforce the AUTH check in mnt3_parse_dir_exports() which is invoked by mnt3_find_export() for subdir mount.
