* gNFS: Fix multi-homed m/c issue in NFS subdir authNiels de Vos2014-07-021-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* rpc: Reconfigure() does not work for auth-rejectSantosh Kumar Pradhan2014-06-241-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If volume is set for rpc-auth.addr.<volname>.reject with value as "host1", ideally the NFS mount from "host1" should FAIL. It works as expected. But when the volume is RESET, then previous value set for auth-reject should go off, and further NFS mount from "host1" should PASS. But it FAILs because of stale value in dict for key "rpc-auth.addr.<volname>.reject". It does not impact rpc-auth.addr.<volname>.allow key because, each time NFS volfile gets generated, allow key ll have "*" as default value. But reject key does not have default value. FIX: Delete the OLD value for key irrespective of anything. Add NEW value for the key, if and only if that is SET in the reconfigured new volfile.

* rpc: warn and truncate grouplist if RPC/AUTH can not hold everythingNiels de Vos2014-05-223-8/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* libgfapi: Added support to fetch volume info from glusterd and store in ↵Soumya Koduri2014-05-121-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glfs object. Defined new APIs in the libgfapi module, given a glfs object, * to send handshake RPC call to glusterd process to fetch UUID of the volume * store it in the glusterfs_context linked to the glfs object. * to parse UUID from its cannonical string format into 16-byte array before sending it to the libgfapi users. Defined a RPC call in glusterd which can be used to query volume related info by other processes using 'clnt_handshake_procs'. Note - Currently this RPC call to glusterd process is used only to fetch UUID. But it can be extended to get other volume related structures as well. In addition to the above, defined a new variable to keep track of such handshake RPCs still in progress to make sure all the corresponding RPC callbacks have been processed before libgfapi returns the glfs object initialized. Also bumping up the GFAPI current version number since there is a new API "glfs_get_volume_id" defined and exposed by libgfapi as part of these changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Two stages of quota enforcement is done: Soft and hard quota Upon reaching soft quota limit on the directory it logs/alerts in the quota daemon log (ie DEFAULT_LOG_DIR/quotad.log) and no more writes allowed after hard quota limit. After reaching the soft-limit the daemon alerts the user/admin repeatively for every 'alert-time', which is configurable. * Quota enforcer is moved to server-side. It takes care of enforcing quota. Since enforcer doesn't have the cluster view, it relies on another service called quota-aggregator. Aggregator, on query can return the size of a directory based on the cluster view. Enforcer is always loaded in the server graph and is by passed if the feature is not enabled. Options specific to enforcer: server-quota - Specifies whether the feature is on/off. It is used to by pass the quota if turned off. deem-statfs - If set to on, it takes quota limits into consideration while estimating fs size. (df command). The algorithm followed is, i. Adjust statvfs based on limit configured on root. ii. If limit is set on the inode passed, use size/limits on that inode to populate statvfs. Otherwise, use size/limits configured on root. iii. Upon statvfs, update the ctx->size on the inode. iv. Don't let DHT aggregate, instead take the maximum of the usages from the subvols of the DHT, since each of it contains the complete information. Enforcer also makes use of gfid-to-path conversion functionality to work correctly when a client like nfs predominently relies on nameless lookups. * Quota Aggregator acts as a thin client to provide cluster view Its a lightweight *gluster client* process with no mount point, started upon enabling quota or restarting the volume. This is a single process run on each brick, which can answer queries on all volumes in the cluster. Its volfile stored in GLUSTERD_DEFAULT_WORKING_DIR/quotad/quotad.vol.

Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes.

* libglusterfs: Add monotonic clocking counter for timer threadHarshavardhana2013-10-151-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cluster/afr: [Feature] Command implementation to get heal-countVenkatesh Somyajulu2013-10-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently to know the number of files to be healed, either user has to go to backend and check the number of entries present in indices/xattrop directory. But if a volume consists of large number of bricks, going to each backend and counting the number of entries is a time-taking task. Otherwise user can give gluster volume heal vol-name info command but with this approach if no. of entries are very hugh in the indices/ xattrop directory, it will comsume time. So as a feature, new command is implemented. Command 1: gluster volume heal vn statistics heal-count This command will get the number of entries present in every brick of a volume. The output displays only entries count. Command 2: gluster volume heal vn statistics heal-count replica 192.168.122.1:/home/user/brickname Here if we are concerned with just one replica. So providing any one of the brick of a replica will get the number of entries to be healed for that replica only. Example: Replicate volume with replica count 2. Backend status: -------------- [root@dhcp-0-17 xattrop]# ls -lia | wc -l 1918 NOTE: Out of 1918, 2 entries are <xattrop-gfid> dummy entries so actual no. of entries to be healed are 1916.

This makes the protocol incompatible with existing roll-outs. It is very confusing when new procedures are added somewhere in the middle of the array. This will cause the number of existing procedures to change. It is much preferred to add new procedures at the end of the array. This changes not only corrects the enum that generates the procedure numbers, but also the ordering in the client and server fops-array for clarity. Correcting this greatly simplifies adding support for these new procedures in Wireshark and will prevent confusion to the people reading network traces (with or without Wireshark).

This differentiation helps in cleaning up resources, at higher layers, in a race-free manner.

This is wrong analysis. cbk_fn is _always_ called. The patch treats ret > 0 as a "missed cbk". ret > 0 only means socket submission was not complete, and is queued to submit asynchronously when POLLOUT is raised. This is sufficient to guarantee that cbkfn is going to be called (either the socket errors or submission succeeds and reply eventually arrives). This commit also removes spurious barrier_wake(s). call backs are guaranteed to be called even if the transport is disconnected. This means, a 'wake' would be called if rpc_clnt_submit is called. Also, we count both successful and failed operations in a particular batch of operations for the synctask_barrier_wait. So, calling synctask_barrier_wake on failure of rpc_clnt_submit (say, due to network failure) would result in a spurious wake.

| | | | | | | | | | | | | | | | | | Problem: For every gluster cli operation from command line rpc init process is required. During init process we print "no transport type set, defaulting to socket" message at WARNING level, which is not necessary. Solution: Moved the log level to DEBUG.

| | | | | | | | | | | | | | | | | | Removing the code which handles "general" options. Since it is no longer possible to set general options which apply for all volumes by default, this was redundant. This cleanup of general options code also solves a bug wherein with nfs.addr-namelookup on, nfs.rpc-auth-reject wouldn't work on ip addresses Change-Id: Iba066e32f9a0255287c322ef85ad1d04b325d739 BUG: 921072 Signed-off-by: Rajesh Amaravathi <rajesh@redhat.com> Reviewed-on: http://review.gluster.org/4691 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

* rpc: before freeing the volume options object, delete it from the listRaghavendra Bhat2013-03-201-6/+6
| | | | | | | | | | | | | | | | | | | | | | * Suppose there is an xlator option which is considered by the xlator only if the source was built with debug mode enabled (the only example in the current code base is run-with-valgrind option for glusterd), then giving that option would make the process crash if the source was not built with debug mode enabled. Reason: In rpc, after getting the options symbol dynamically, it was stored in the newly allocated volume options structure and the structure's list head was added to the xlator's volume_options list. But while freeing the structure the list was not deleted. Thus when the list was traversed, already freed structure was accessed leading to segfault.

| | | | | | | | | | | | | | | | | | * requests coming in as root are converted to nfsnobody * with open-behind some acl checks wont happen and nfsnobody can read the file "whose owner is root and other users do not have permission to read the file". This is becasue open-behind does not send the open to the brick and sends success to the application, thus the acl related tests on the file wont happen which would have prevented the file from being opened.
