* gNFS: Fix memory leak in setacl code pathNiels de Vos2014-09-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ACL is set on a file in Gluster NFS mount (setfacl command), and it succeed, then the NFS call state data is leaked. Though all the failure code path frees up the memory. Impact: There is a OOM kill i.e. vdsm invoked oom-killer during rebalance and Killed process 4305, UID 0, (glusterfs nfs process) FIX: Make sure to deallocate the memory for call state in acl3_setacl_cbk() using nfs3_call_state_wipe(); Cherry picked from commit 5c869aea79c0f304150eac014c7177e74ce0852e: > Change-Id: I9caa3f851e49daaba15be3eec626f1f2dd8e45b3 > BUG: 1139195 > Signed-off-by: Santosh Kumar Pradhan <spradhan@redhat.com> > Reviewed-on: http://review.gluster.org/8651 > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Niels de Vos <ndevos@redhat.com> Change-Id: I9caa3f851e49daaba15be3eec626f1f2dd8e45b3 BUG: 1139244 Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: http://review.gluster.org/8654 Reviewed-by: Santosh Pradhan <spradhan@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* build: make GLUSTERD_WORKDIR rely on localstatedirHarshavardhana2014-09-032-5/+3
| | | | | | | | | | | | | | | | | | | | | | | Backport from master branch - http://review.gluster.org/#/c/8246/ - 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. gluster volume set nfs-ganesha.enable ON/OFF If the option is set to ON, the volume field in the nfs-ganesha configuartion file is edited. Gluster-nfs is disabled on that volume and the volume is exported using nfs-ganesha. 2.gluster volume set nfs-ganesha.host IP This is used to provide the IP of the nfs-ganesha host. Note : nfs-ganesha.host MUST be set before using nfs-ganesha.enable ON The switch from gluster-nfs to nfs-ganesha is mostly done by the hook-scripts in the post phase of the 'set' option. As a result, gluster volume reset does not function as it is expected to. By default, nfs-ganesha will be set to off but the process will not be killed. Hence, a few changes have to be made post 'reset' option as well. Those changes also have been added.

* rpc: warn and truncate grouplist if RPC/AUTH can not hold everythingNiels de Vos2014-04-081-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GlusterFS protocol currently uses AUTH_GLUSTERFS_V2 in the RPC/AUTH header. This header contains the uid, gid and auxiliary groups of the user/process that accesses the Gluster Volume. The AUTH_GLUSTERFS_V2 structure allows up to 65535 auxiliary groups to be passed on. Unfortunately, the RPC/AUTH header is limited to 400 bytes by the RPC specification: http://tools.ietf.org/html/rfc5531#section-8.2 In order to not cause complete failures on the client-side when trying to encode a AUTH_GLUSTERFS_V2 that would result in more than 400 bytes, we can calculate the expected size of the other elements: 1 | pid 1 | uid 1 | gid 1 | groups_len XX | groups_val (GF_MAX_AUX_GROUPS=65535) 1 | lk_owner_len YY | lk_owner_val (GF_MAX_LOCK_OWNER_LEN=1024) ----+------------------------------------------- 5 | total xdr-units one XDR-unit is defined as BYTES_PER_XDR_UNIT = 4 bytes MAX_AUTH_BYTES = 400 is the maximum, this is 100 xdr-units. XX + YY can be 95 to fill the 100 xdr-units. Note that the on-wire protocol has tighter requirements than the internal structures. It is possible for xlators to use more groups and a bigger lk_owner than that can be sent by a GlusterFS-client. This change prevents overflows when allocating the RPC/AUTH header. Two new macros are introduced to calculate the number of groups that fit in the RPC/AUTH header, when taking the size of the lk_owner in account. In case the list of groups exceeds the maximum possible, only the first groups are passed over the RPC/GlusterFS protocol to the bricks. A warning is added to the logs, so that most system administrators will get informed. The reducing of the number of groups is not a new inventions. The RPC/AUTH header (AUTH_SYS or AUTH_UNIX) that NFS uses has a limit of 16 groups. Most, if not all, NFS-clients will reduce any bigger number of groups to 16. (nfs.server-aux-gids can be used to workaround the limit of 16 groups, but the Gluster NFS-server will be limited to a maximum of 93 groups, or fewer in case the lk_owner structure contains more items.)

Problem: Couple of issues are seen when NFS-ACL is turned ON. i.e. i) NFS directory access is too slow, impacting customer workflows with ACL ii)dbench fails with 100 directories. 2. Root cause: Frequent cache invalidation in the client side when ACL is turned ON with NFS because NFS server getacl() code returns the wrong fsid to the client. 3. This attr-cache invlaidation triggers the frequent LOOKUP ops for each file instead of relying on the readdir or readdirp data. As a result performance gets impacted. 4. In case of dbench workload, the problem is more severe. e.g. Client side rpcdebug output: =========================== Dec 16 10:16:53 santosh-3 kernel: NFS: nfs_update_inode(0:1b/12061953567282551806 ct=2 info=0x7e7f) Dec 16 10:16:53 santosh-3 kernel: NFS: nfs_fhget(0:1b/12061953567282551806 ct=2) Dec 16 10:16:53 santosh-3 kernel: <-- nfs_xdev_get_sb() = -116 [splat] Dec 16 10:16:53 santosh-3 kernel: nfs_do_submount: done Dec 16 10:16:53 santosh-3 kernel: <-- nfs_do_submount() = ffffffffffffff8c Dec 16 10:16:53 santosh-3 kernel: <-- nfs_follow_mountpoint() = ffffffffffffff8c Dec 16 10:16:53 santosh-3 kernel: NFS: dentry_delete(clients/client77, 20008) As per Jeff Layton, This occurs when the client detects that the fsid on a filehandle is different from its parent. At that point, it tries to do a new submount of the new filesystem onto the correct point. It means client got a superblock reference for the new fs and is now looking to set up the root of the mount. It calls nfs_get_root to do that, which basically takes the superblock and a filehandle and returns a dentry. The problem here is that the dentry->d_inode you're getting back looks wrong. It's not a directory as expected -- it's something else. So the client gives up and tosses back an ESTALE. Which clearly says that, In getacl() code while it does the stat() call to get the attrs, it forgets to populate the deviceid or fsid before going ahead and does getxattr(). FIX: 1. Fill the deviceid in iatt. 2. Do bit more clean up for the confusing part of the code. NB: Many many thanks to Niels de Vos and Jeff Layton for their help to debug the issue.

* libglusterfs: Add monotonic clocking counter for timer threadHarshavardhana2013-10-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gettimeofday() returns the current wall clock time and timezone. Using these functions in order to measure the passage of time (how long an operation took) therefore seems like a no-brainer. This time suffer's from some limitations: a. They have a low resolution: “High-performance” timing by definition, requires clock resolutions into the microseconds or better. b. They can jump forwards and backwards in time: Computer clocks all tick at slightly different rates, which causes the time to drift. Most systems have NTP enabled which periodically adjusts the system clock to keep them in sync with “actual” time. The adjustment can cause the clock to suddenly jump forward (artificially inflating your timing numbers) or jump backwards (causing your timing calculations to go negative or hugely positive). In such cases timer thread could go into an infinite loop. From 'man gettimeofday': ---------- .. .. The time returned by gettimeofday() is affected by discontinuous jumps in the system time (e.g., if the system administrator manually changes the system time). If you need a monotonically increasing clock, see clock_gettime(2). .. .. ---------- Rationale: For calculating interval timing for Timer thread, all that’s needed should be clock as a simple counter that increments at a stable rate. This is necessary to avoid the jumps which are caused by using "wall time", this counter must be monotonic that can never “tick” backwards, ever.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce /var/lib/glusterfs/nfs/rmtab to contain a list of NFS-clients which have a volume mounted. The volume option 'nfs.mount-rmtab' can be set to an alternative filename. When the file is located on shared storage, multiple gNFS servers can use the same file to present a single NFS-server. This cache is read when a system administrator calls 'showmount -a' and updated when an NFS-client calls MNT or UMNT from the MOUNT protocol. Usage: - create a volume for storing the shared rmtab file - mount the volume on all storage servers, at the same location - make sure that the volume is mounted at boot (add to /etc/fstab) - place the rmtab file on the volume: # gluster volume set <VOLUME> nfs.mount-rmtab <MOUNTPOINT>/<FILENAME> - any subsequent mount requests will add an entry to this file - 'showmount -a' requests will return the NFS-clients using the cluster Note: The NFS-server does currently not support reconfigure(). When a configuration option is set/changed, the NFS-server glusterfs process gets restarted. This causes the active NFS-clients to be forgotten (the entries are saved in the old rmtab, but we do not have a reference to that file any more, so we can't re-add them). Therefor a re-mount done by the NFS-clients is needed before they get listed in the rmtab again.
