* mem-pool: initialize pthread_key_t pool_key in mem_pool_init_early()Niels de Vos2017-07-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not possible to call pthread_key_delete for the pool_key that is intialized in the constructor for the memory pools. This makes it difficult to do a full cleanup of all the resources in mem_pools_fini(). For this, the initialization of pool_key should be moved to mem_pool_init(). However, the glusterfsd binary has a rather complex initialization procedure. The memory pools need to get initialized partially to get mem_get() functionality working. But, the pool_sweeper thread can get killed in case it is started before glusterfsd deamonizes. In order to solve this, mem_pools_init() is split into two pieces: 1. mem_pools_init_early() for initializing the basic structures 2. mem_pools_init_late() to start the pool_sweeper thread With the split of mem_pools_init(), and placing the pthread_key_create() in mem_pools_init_early(), it is now possible to correctly cleanup the pool_key with pthread_key_delete() in mem_pools_fini(). It seems that there was no memory pool initialization in the CLI. This has been added as well now. Without it, the CLI will not be able to call mem_get() successfully which results in a hang of the process.

* glusterd: socketfile & pidfile related fixes for brick multiplexing featureMohit Agrawal2017-05-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: While brick-muliplexing is on after restarting glusterd, CLI is not showing pid of all brick processes in all volumes. Solution: While brick-mux is on all local brick process communicated through one UNIX socket but as per current code (glusterd_brick_start) it is trying to communicate with separate UNIX socket for each volume which is populated based on brick-name and vol-name.Because of multiplexing design only one UNIX socket is opened so it is throwing poller error and not able to fetch correct status of brick process through cli process. To resolve the problem write a new function glusterd_set_socket_filepath_for_mux that will call by glusterd_brick_start to validate about the existence of socketpath. To avoid the continuous EPOLLERR erros in logs update socket_connect code. Test: To reproduce the issue followed below steps 1) Create two distributed volumes(dist1 and dist2) 2) Set cluster.brick-multiplex is on 3) kill glusterd 4) run command gluster v status After apply the patch it shows correct pid for all volumes BUG: 1444596 Change-Id: I5d10af69dea0d0ca19511f43870f34295a54a4d2 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: https://review.gluster.org/17101 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Prashanth Pai <ppai@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* core: make the per glusterfs_ctx_t timer-wheel refcountedNiels de Vos2017-05-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | xlators can use a 'global' timer-wheel for scheduling events. This timer-wheel is managed per glusterfs_ctx_t, but does not need to be allocated for every graph. When an xlator wants to use the timer-wheel, it will be instanciated on demand, and provided to xlators that request it later on. By adding a reference counter to the glusterfs_ctx_t for the timer-wheel, the threads and structures can be cleaned up when the last xlator does not have a need for it anymore. In general, the xlators request the timer-wheel in init(), and they should return it in fini(). Because the timer-wheel is managed per glusterfs_ctx_t, the functions can be added to ctx.c and do not need to live in their very minimal tw.[ch] files.

* libglusterfs: make memory pools more thread-friendlyJeff Darcy2017-02-021-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Early multiplexing tests revealed *massive* contention on certain pools' global locks - especially for dictionaries and secondarily for call stubs. For the thread counts that multiplexing can create, a more lock-free solution is clearly needed. Also, the current mem-pool implementation does a poor job releasing memory back to the system, artificially inflating memory usage to match whatever the worst case was since the process started. This is bad in general, but especially so for multiplexing where there are more pools and a major point of the whole exercise is to reduce memory consumption. The basic ideas for the new design are these There is one pool, globally, for each power-of-two size range. Every attempt to create a new pool within this range will instead add a reference to the existing pool. Instead of adding pools for each translator within each multiplexed brick (potentially infinite and quite possibly thousands), we allocate one set of size-based pools per *thread* (hundreds at worst). Each per-thread pool is divided into hot and cold lists. Every allocation first attempts to use the hot list, then the cold list. When objects are freed, they always go on the hot list. There is one global "pool sweeper" thread, which periodically reclaims everything in each pool's cold list and then "demotes" the current hot list to be the new cold list. For normal allocation activity, only a per-thread lock need be taken, and even that only to guard against very rare contention from the pool sweeper. When threads start and stop, a global lock must be taken to add them to the pool sweeper's list. Lock contention is therefore extremely low, and the hot/cold lists also provide good locality. A more complete explanation (of a similar earlier design) can be found here: http://www.gluster.org/pipermail/gluster-devel/2016-October/051160.html Change-Id: I5bc8a1ba57cfb553998f979a498886e0d006e665 BUG: 1385758 Signed-off-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-on: https://review.gluster.org/15645 Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-2/+7
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Milind Changire reported that GlusterFS fails to build on RHEL5 because linux/oom.h is unavailable. Milind's initial patch disables OOM adjustment completely for those environments that do not have this header. However, I'd take another approach that: 1) checks for linux/oom.h in compile-time and defines necessary constants if the header is not present; 2) checks for available OOM API in /proc in run-time and uses it accordingly. This allows OOM to be adjusted properly on RHEL5 (the kernel is pretty new to present /proc API for that) as well as RHEL6 (the kernel has many thing backported including new /proc API).

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-041-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.

Capabilities can be used without selinux, hence if selinux is disabled, security.capability cannot be forbidden. Hence adding a new mount option called capability. Only when "--capability" or "--selinux" mount option is used, security.capability is sent to the brick, else it is forbidden.

* fuse: add "resolve-gids" mount option to overcome 32-groups limitNiels de Vos2015-08-051-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a --resolve-gids commandline option to the glusterfs binary. This option gets set when executing "mount -t glusterfs -o resolve-gids ...". This option is most useful in combination with the "acl" mount option. POSIX ACL permission checking is done on the FUSE-client side to improve performance (in addition to the checking on the bricks). The fuse-bridge reads /proc/$PID/status by default, and this file contains maximum 32 groups. Any local (client-side) permission checking that requires more than the first 32 groups will fail. By enabling the "resolve-gids" option, the fuse-bridge will call getgrouplist() to retrieve all the groups from the user accessing the mountpoint. This is comparable to how "nfs.server-aux-gids" works. Note that when a user belongs to more than ~93 groups, the volume option server.manage-gids needs to be enabled too. Without this option, the RPC-layer will need to reduce the number of groups to make them fit in the RPC-header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem 1 : glusterd was crashing due to race between clean up thread and rpc event thread. Scenario: As we can observed, X thread is in the process of exiting the process. It has already run the exit handlers, which cleanup things that require cleaning up. This includes liburcu resources. By the time Y thread called rcu_bp_register(), the liburcu resources have been cleaned up. rcu_bp_register() tries to access these non-existent resources, which leads to the segmentation fault. Note1: Crash happen when the process is almost at the point of stopping(exiting), it doesn't have any serious impact to functionality apart from creating the core dump file and the log message. Fix .Do proper clean up before calling exit(). Note2: Other xlator have clean up issues,so only glusterd clean up function invoked. Note3: This patch also solve the selinux issue. Problem 2 : glusterd runs as rpm_script_t when it's executed from the rpm scriptlet,files created in this context are set as rpm_script_t, so glusterd unable to access these files when it runs in glusterd_t context. Fix: Fini clean up the files while glusterd exiting, so files are recreated by glusterd while starting with proper SElinux context label.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Instantiate a process wide global instance of the timer wheel data structure. Spawning glusterfs* process with option arg "--global-timer-wheel" instantiates a global instance of timer-wheel under global context (->ctx). Translators can make use of this process wide instance [via a call to glusterfs_global_timer_wheel()] instead of maintaining an instance of their own and possibly consuming more memory. Linux kernel too has a single instance of timer wheel where subsystems such as IO, networking, etc.. make use of. Bitrot daemon would be early consumers of this: bitrot translator instances for multiple volumes would track objects belonging to their respective bricks in this global expiry tracking data structure. This is also a first step to move GlusterFS timer mechanism to use timer-wheel.

Without establishing a total ordering of events, we can't guarantee that cluster xlators like afr, dht perceive them in the same order. While we would expect afr (say) to perceive it as only one of Brick1 and Brick2 going down at any given time, it is possible for the notification of Brick2 going offline to race with the notification of Brick1 coming back online.

Currently with the multi thread epoll patch, it is possible to have more than one thread waiting on socket activity and processing the same. This thread count is currently static, which this commit makes dynamic. The current services which use IO path, i.e brick processes, any client process (nfs, FUSE, gfapi, heal, rebalance, etc.a), gain 2 set parameters to control the number of threads that are processing events. These settings are, - client.event-threads <n> - server.event-threads <n> The client setting affects the client graph consumers, and the server setting affects the brick processes. These are processed and inited/reconfigured using the client/server protocol xlators. Other services (say glusterd) would need to extend similar configuration settings to take advantage of multi threaded event processing. At present glusterd is not enabled with this commit, as it does not stand to gain from this multi-threading (as I understand it).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The feature is controlled by presence of the following file: /var/lib/glusterd/secure-access See the comment near the definition of SECURE_ACCESS_FILE in glusterfs.h for the rationale. With this enabled, the following rules apply to connections: UNIX-domain sockets never have SSL. Management-port sockets (both connecting and accepting, in daemons and CLI) have SSL based on presence of the file. Other IP sockets have SSL based on the existing client.ssl and server.ssl volume options. Transport multi-threading is explicitly turned off in glusterd (it would otherwise be turned on when SSL is) due to multi-threading issues. Tests have been elided to avoid risk of leaving a file which will cause all subsequent tests to run with management SSL still enabled. IMPLEMENTATION NOTE The implementation is a bit messy, and consists of two stages. First we decide whether to set the relevant fields in our context structure, based on presence of the sentinel file OR a command-line override. Later we decide whether a particular connection should actually use SSL, based on the context flags plus what kind of connection we're making[1] and what kind of daemon we're in[2]. [1] inbound, outbound to glusterd port, other outbound [2] glusterd, glusterfsd, other TESTING NOTE Instead of just running one special test for this feature, the ideal would be to run all tests with management SSL enabled. However, it would be inappropriate or premature to set up an optional feature in the patch itself. Therefore, the method of choice is to submit a separate patch on top, which modifies "cleanup" in include.rc to recreate the secure-access file and associated SSL certificate/key files before each test.

* log: enhance gluster log format with message ID and standardize errno reportingShyamsundarR2014-03-281-166/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* protocol/server: do not do root-squashing for trusted clientsRaghavendra Bhat2014-02-101-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
