* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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/nlm: keep track of the call-state and frame for notificationsNiels de Vos2017-07-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When blocking locks are used, a new frame is allocated that is used to send the notification to the client once once the lock becomes available. In all other cases, the frame that contains the request from the client will be used for the reply. Because there was no way to track the different clients with their requests (captured in the call-state), the call-state could be free'd before the notification was sent to the client. This caused a use-after-free of the call-state and could trigger segfaults of the Gluster/NFS server or incorrect replies on (un)lock requests. By introducing a nlm4_notify_args structure, the call-state and frame can be tracked better. This prevents the possibility of segfaulting when the call-state is used after being free'd.

| | | | | | | | | | | | | | | | | | | | | | | NFS now has the ability to use a separate file for "netgroups" and "exports".

* nfs: add structures and functions for parsing netgroupsNiels de Vos2015-03-111-0/+1
| | | | | | | | | | | | | | | | | | | | Netgroups are often used by enterprises to group a set of systems. The NFS /etc/exports file support the @netgroup notation, and Gluster/NFS will get extended to support this notation as well. For this, it is needed that Gluster/NFS learns to parse the netgroup format. A change to glusterfsd (Change-Id I24c40d5) will add test cases where the parsing is used for regression testing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * This change introduces four NLMv4 procedures: NM_LOCK, SHARE, UNSHARE and FREE_ALL. These are used by PC clients (windows/dos) to control access to files. 1. NM_LOCK: this lock is not monitored by statd. 2. SHARE: A share reservation is a lock on the whole file that is taken whenever a file is opened on windows clients. This has ACCESS (N, R, W, RW) and DENY MODE (N, R, W, RW). ACCESS: mode of access requested by the client; DENY MODE: what the requesting client wants to deny other clients. 3. UNSHARE: remove a share reservation obtained by SHARE. Called while closing a file. 4. FREE_ALL: remove all share reservations and locks, both monitored and unmonitored, of the calling client. * lock and nm_lock use a common function with only a flag conveying whether or not to monitor a lock. * NOTES: 1. SHARE reservations are not STACK_WIND'd to subsequent xlators. These are maintained in-memory in the nfs xlator. 2. Consequently, for SHARE reservations to work effectively, all PC clients *must* mount from the same gNfs server. Not doing so will result in different servers maintaining separate SHARE reservations which will not be enforced for obvious reasons.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overall, the aim of this patch is to change the result of an nfs op depending on whether the underlying volume is up or down as notified by CHILD_UP and CHILD_DOWN events. This patch contains three intertwined changes: o Only when the lookup on the root of a volume is successful does gnfs now export the subvolume. Till now the result of the lookup was not used to determine whether we should export that volume. Not accounting for root lookup failure resulted in ESTALEs on first access because some children of distribute were down at the time of the root lookup. o Only when lookups on all the subvolumes have succeeded are these exports enabled through NFS. o When a child of say distribute goes down, on CHILD_DOWN event nfs will ignore all incoming requests from the client because ignoring these will prevent ESTALEs for those requests and in the hope that ignoring the requests will make the client retransmit. There are risks in this approach absent the DRC but we're willing to live with that for now. When a child goes down, the mount exports list will continue to show it but mount requests will be denied.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfsx has followed traditional approach of exporting whole volumes as NFS exports. The Platform requires and some users have approached us for introducing exports of only specific directories instead of full Gluster volumes. This commit introduces this support through two nfsx options: Option 1: ========= option nfs3.<volume-name>.export-dir <subdir1-in-vol>,<subdir2-in-vol>,..<subdirN-in-vol> export-dir will allow the export of a particular dir as a single export by itself. For eg.: volume posix type storage/posix option directory /export/ end-volume volume posix-ac type features/access-control subvolumes posix end-volume volume nfs type nfs/server subvolumes posix-ac option rpc-auth.addr.allow * option nfs3.posix-ac.export-dir /homes/shehjart end-volume A comma separate list of sub-directories will set up those dirs as separated exports. At the nfs client, the mount command will be: $ mount <nfsserver>:/posix-ac/homes/shehjart /mnt Option 2: ========= option nfs3.<volume-name>.export-volumes <on|off> There can be situations where users only want the directory level exports and require that volume exports be completely disabled. The above option allows us to do this. By default, volume exports are enabled. From the earlier example, replacing <volume-name> with posix-ac, will disable mounting of the posix-ac volume as a whole. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.
