* features/changelog: Capture "correct" internal FOPsVenky Shankar2014-07-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes changelog capturing internal FOPs in a cascaded setup, where the intermediate master would record internal FOPs (generated by DHT on link()/rename()). This is due to I/O happening on the intermediate slave on geo-replication's auxillary mount with client-pid -1. Currently, the internal FOP capturing logic depends on client pid being non-negative and the presence of a special key in dictionary. Due to this, internal FOPs on an inter-mediate master would be recorded in the changelog. Checking client-pid being non-negative was introduced to capture AFR self-heal traffic in changelog, thereby breaking cascading setups. By coincidence, AFR self-heal daemon uses -1 as frame->root->pid thereby making is hard to differentiate b/w geo-rep's auxillary mount and self-heal daemon.

* glusterd: Improvements to peer identificationKaushal M2014-07-151-0/+3

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.

* gNFS: Fix multi-homed m/c issue in NFS subdir authSantosh Kumar Pradhan2014-06-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The default changelog-barrier-timeout is set to 120 sec which is same as barrier-timeout of barrier translator. On this timeout, all the barriered fops are unbarriered. It is safe to have this internal timeout for changelog barrier to prevent it from indefinite barrierring of fops if barrier disable notification does not come from snapshot for some reason.

* log: enhance gluster log format with message ID and standardize errno reportingShyamsundarR2014-03-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are quite a slew of logs in Gluster that do not lend themselves to trivial analysis by various tools that help collect and monitor logs, due to the textual nature of the logs. This FEAT is to make this better by giving logs message IDs so that the tools do not have to do complex log parsing to break it down to problem areas and suggest troubleshooting options. With this patch, a new set of logging APIs are introduced that take additionally a message ID and an error number, so as to print the message ID and the descriptive string for the error. New APIs: - gf_msg, gf_msg_debug/trace, gf_msg_nomem, gf_msg_callingfn These APIs follow the functionality of the previous gf_log* counterparts, and hence are 1:1 replacements, with the delta that, gf_msg, gf_msg_callingfn take additional parameters as specified above. Defining the log messages: Each invocation of gf_msg/gf_msg_callingfn, should provide an ID and an errnum (if available). Towards this, a common message id file is provided, which contains defines to various messages and their respective strings. As other messages are changed to the new infrastructure APIs, it is intended that this file is edited to add these messages as well. Framework enhanced: The logging framework is also enhanced to be able to support different logging backends in the future. Hence new configuration options for logging framework and logging formats are introduced. Backward compatibility: Currently the framework supports logging in the traditional format, with the inclusion of an error string based on the errnum passed in. Hence the shift to these new APIs would retain the log file names, locations, and format with the exception of an additional error string where applicable. Testing done: Tested the new APIs with different messages in normal code paths Tested with configurations set to gluster logs (syslog pending) Tested nomem variants, inducing the message in normal code paths Tested ident generation for normal code paths (other paths pending) Tested with sample gfapi program for gfapi messages Test code is stripped from the commit Pending work (not to be addressed in this patch (future)): - Logging framework should be configurable - Logging format should be configurable - Once all messages move to the new APIs deprecate/delete older APIs to prevent misuse/abuse using the same - Repeated log messages should be suppressed (as a configurable option) - Logging framework assumes that only one init is possible, but there is no protection around the same (in existing code) - gf_log_fini is not invoked anywhere and does very little cleanup (in existing code) - DOxygen comments to message id headers for each message Change-Id: Ia043fda99a1c6cf7817517ef9e279bfcf35dcc24 BUG: 1075611 Signed-off-by: ShyamsundarR <srangana@redhat.com> Reviewed-on: http://review.gluster.org/6547 Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

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.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). 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.

This prevents options containing whitespace to be written to the volfiles which would cause the volfile parser to fail.
