* protocol/server: do not do root-squashing for trusted clientsRaghavendra Bhat2014-02-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * As of now clients mounting within the storage pool using that machine's ip/hostname are trusted clients (i.e clients local to the glusterd). * Be careful when the request itself comes in as nfsnobody (ex: posix tests). So move the squashing part to protocol/server when it creates a new frame for the request, instead of auth part of rpc layer. * For nfs servers do root-squashing without checking if it is trusted client, as all the nfs servers would be running within the storage pool, hence will be trusted clients for the bricks. * Provide one more option for mounting which actually says root-squash should/should not happen. This value is given priority only for the trusted clients. For non trusted clients, the volume option takes the priority. But for trusted clients if root-squash should not happen, then they have to be mounted with root-squash=no option. (This is done because by default blocking root-squashing for the trusted clients will cause problems for smb and UFO clients for which the requests have to be squashed if the option is enabled). * For geo-replication and defrag clients do not do root-squashing. * Introduce a new option in open-behind for doing read after successful open.

* features/quota: Improvements to quotaRaghavendra G2013-11-261-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* features/changelog: changelog translatorAvra Sengupta2013-07-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial version of the Changelog Translator. What is it ----------- Goal is to capture changes performed on a GlusterFS volume. The translator needs to be loaded on the server (bricks) and captures changes in a plain text file inside a configured directory path (controlled by "changelog-dir", should be somewhere in <export>/.glusterfs/changelog by default). Changes are classified into 3 types: - Data: : TYPE-I - Metadata : TYPE-II - Entry : TYPE-III Changelog file is rolled over after a certain time interval (defauls to 60 seconds) after which a changelog is started. The thing to be noted here is that for a time interval (time slice) multiple changes for an inode are recorded only once (ie. say for 100+ writes on an inode that happens within the time slice has only a single corresponding entry in the changelog file). That way we do not bloat up the changelog and also save lots of writes. Changelog Format ----------------- TYPE-I and TYPE-II changes have the gfid on the entity on which the operation happened. TYPE-III being a entry op requires the parent gfid and the basename. Changelog format has been kept to a minimal and it's upto the consumers to do the heavy loading of figuring out deletes, renames etc.. A single changelog file records all three types of changes, with each change starting with an identifier ("D": DATA, "M": METADATA and "E": ENTRY). Option is provided for the encoding type (See TUNABLES). Consumers ---------- The only consumer as of today would be geo-replication, although backup utilities, self-heal, bit-rot detection could be possible consumers in the future. CLI ---- By default, change-logging is disabled (the translator is present in the server graph but does nothing). When enabled (via cli) each brick starts to log the changes. There are a set of tunable that can be used to change the translators behaviour: - enable/disable changelog (disabled by default) gluster volume set <volume> changelog {on|off} - set the logging directory (<brick>/.glusterfs/changelogs is the default) gluster volume set <volume> changelog-dir /path/to/dir - select encoding type (binary (default) or ascii) gluster volume set <volume> encoding {binary|ascii} - change the rollover time for the logs (60 secs by default) gluster volume set <volume> rollover-time <secs> - when secs > 0, changelog file is not open()'d with O_SYNC flag - and fsync is trigerred periodically every <secs> seconds. gluster volume set <volume> fsync-interval <secs> features/changelog: changelog consumer library (libgfchangelog) A shared library is provided for the consumer of the changelogs for easy acess via APIs. Application can link against this library and request for changelog updates. Conversion of binary logs to human-readable ascii format is also taken care by the library which keeps a copy of the changelog in application provided working directory.

However we perform pre-processing on the graph we receive from the server, like adding ACL translator, applying --xlator-option cli params, etc. So print the serialized in-memory graph as the "volfile" in the log. This can be very handy to double check if certain --xlator-option param actually got applied or not, and in general is showing a "truer" representation of the real graph actually used.

It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2012-06-291-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of nit-level issues throughout the source with the use of localtime and ctime. While they apparently aren't causing too many problems, apart from the one in bz 828058, they ought to be fixed. Among the "real" problems that are fixed in this patch: 1) general localtime and ctime not MT-SAFE. There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

* Replace GPLV3 MD5 with OpenSSL MD5Kaleb KEITHLEY2012-04-041-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ric asked me to look at replacing the GPL licensed MD5 code with something better, i.e. perhaps faster, and with a less restrictive license, etc. So I took a couple hour holiday from working on wrapping up the client_t and did this. OpenSSL (nee SSLeay) is released under the OpenSSL license, a BSD/MIT style license. OpenSSL (libcrypto.so) is used on Linux, OS X and *BSD, Open Solaris, etc. IOW it's universally available on the platforms we care about. It's written by Eric Young (eay), now at EMC/RSA, and I can say from experience that the OpenSSL implementation of MD5 (at least) is every bit as fast as RSA's proprietary implementation (primarily because the implementations are very, very similar.) The last time I surveyed MD5 implementations I found they're all pretty much the same speed. I changed the APIs (and ABIs) for the strong and weak checksums. Strictly speaking I didn't need to do that. They're only called on short strings of data, i.e. pathnames, so using int32_t and uint32_t is ostensibly okay. My change is arguably a better, more general API for this sort of thing. It's also what bit me when gerrit/jenkins validation failed due to glusterfs segv-ing. (I didn't pay close enough attention to the implementation of the weak checksum. But it forced me to learn what gerrit/jenkins are doing and going forward I can do better testing before submitting to gerrit.)

* core/setxattr: prevent users from setting glusterfs xattrsRajesh Amaravathi2012-01-141-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | * Each xlator prevents the user from setting glusterfs-internal xattrs like trusted.gfid by handling it in respective setxattr functions. The speacial case of trusted.gfid is handled in fuse (Not in posix because posix_setxattr is used to set gfid). * For xlators which did not define setxattr and/or fsetxattr, the functions have been implemented with appropriate checks. xlator | fops-added _______________|__________________________ | 1. afr | fsetxattr 2. stripe | setxatrr and fsetxattr 3. quota | setxattr and fsetxattr Change-Id: Ib62abb7067415b23a708002f884d30e8866fbf48 BUG: 765487 Signed-off-by: Rajesh Amaravathi <rajesh@redhat.com> Reviewed-on: http://review.gluster.com/685 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com>
