* libglusterfs: Handle FS errors gracefullyPranith Kumar K2017-11-222-93/+167
| | | | | | | | | | | | | | | Problem: FS sometimes doesn't give the expected return values. We need our common functions to guard against this. Example BUG: https://bugzilla.redhat.com/show_bug.cgi?id=864401 Fix: When the return value is not as per specification, change the return value to -1 and errno to EIO BUG: 1469487 Change-Id: I14739ab2e5ae225b1a91438b87f8928af56f2934 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* cluster-syncop: Implement tiebreaker inodelk/entrylkPranith Kumar K2017-11-222-0/+103
| | | | | | | | | | | | In this implementation, inodelk/entrylk will be tried for the subvols given with trylock. In this attempt if all locks are obtained, then inodelk is successful, otherwise, if it gets success on the first available subvolume, then it will go for blocking lock, where as other subvolumes will not try and this acts as tie-breaker.

* timer: Fix possible race during cleanupSoumya Koduri2017-11-211-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mentioned in bug1509189, there is a possible race between gf_timer_cancel(), gf_timer_proc() and gf_timer_registry_destroy() leading to use_after_free. Problem: 1) gf_timer_proc() is called, locks reg, and gets an event. It unlocks reg, and calls the callback. 2) Meanwhile gf_timer_registry_destroy() is called, and removes reg from ctx, and joins on gf_timer_proc(). 3) gf_timer_call_cancel() is called on the event being processed. It cannot find reg (since it's been removed from reg), so it frees event. 4) the callback returns into gf_timer_proc(), and it tries to free event, but it's already free, so double free. Solution: The fix is to bail out in gf_timer_cancel() when registry is not found. The logic behind this is that, gf_timer_cancel() is called only on any existing event. That means there was a valid registry earlier while creating that event. And the only reason we cannot find that registry now is that it must have got set to NULL when context cleanup is started. Since gf_timer_proc() takes care of releasing all the remaining events active on that registry, it seems safe to bail out in gf_timer_cancel().

* rpc : Change the way client uuid is builtPoornima G2017-11-201-24/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Today the main users of client uuid are protocol layers, locks, leases. Protocol layers requires each client uuid to be unique, even across connects and disconnects. Locks and leases on the server side also use the same client uid which changes across file migrations. Which makes the graph switch and file migration tedious for locks and leases. file migration across bricks becomes difficult as client uuid for the same client, is different on the other brick. The exact set of issues exists for leases as well. Solution would be to introduce a constant in the client-uid string which the locks and leases can use to identify the owner client across bricks. Client uuid currently: %s(ctx uuid)-%s(protocol client name)-%d(graph id)%s(setvolume count/reconnect count) Proposed Client uuid: "CTX_ID:%s-GRAPH_ID:%d-PID:%d-HOST:%s-PC_NAME:%s-RECON_NO:%s" - CTX_ID: This is will be constant per client. - GRAPH_ID, PID, HOST, PC_NAME(protocol client name), RECON_NO(setvolume count) remains the same.

* libglusterfs/options: Add new member 'setkey' to xlator optionsKaushal M2017-11-151-0/+4
| | | | | | | | | | | | | | | | | The 'setkey' will be used as the key by GD2 when setting the option during volgen. 'setkey' also supports using varstrings. This is mainly to be used for options, which use a different key for 'volume set' and in volfiles. For eg. the 'auth.*' options of protocol/server. The protocol/server xlator has been updated to make use of this for the auth.allow and auth.reject options.

* libglusterfs/atomic: Improved atomic supportXavier Hernandez2017-11-141-72/+425
| | | | | | | | | | | | | | | | This patch solves a detection problem in configure.ac that prevented that compilation detects builtin __atomic or __sync functions. It also adds more atomic types and support for other atomic functions. An special case has been added to support 64-bit atomics on 32-bit systems. The solution is to fallback to the mutex solution only for 64-bit atomics, but smaller atomic types will still take advantage of builtins if available.

* event/epoll: don't call handler for events received after a pollerrRaghavendra G2017-09-061-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | we register socket with EPOLLONESHOT, which means it has to be explicitly added back through epoll_ctl to receive more events. Normally we do this once the handler completes processing of current event. But event_select_on_epoll is one asynchronous codepath where socket can be added back for polling while an event on the same socket is being processed. event_select_on_epoll has a check whether an event is being processed in the form of slot->in_handler. But this check is not sufficient enough to prevent parallel events as slot->in_handler is not atomically incremented with respect to reception of the event. This means following imaginary sequence of events can happen: * epoll_wait returns with a POLLERR - say POLLERR1 - on a socket (sock1) associated with slot s1. socket_event_handle_pollerr is yet to be invoked. * an event_select_on called from __socket_ioq_churn which was called in request/reply/msg submission codepath (as opposed to __socket_ioq_churn called as part of POLLOUT handling - we cannot receive a POLLOUT due to EPOLLONESHOT) adds back sock1 for polling. * since sock1 was added back for polling in step 2 and our polling is level-triggered, another thread picks up another POLLERR event - say POLLERR2. socket_event_handler is invoked as part of processing POLLERR2 and it completes execution setting priv->sock to -1. * event_unregister_epoll called as part of __socket_reset due to POLLERR1 would receive fd as -1 resulting in assert failure. Also, since the first pollerr event has done rpc_transport_unref, subsequent parallel events (not just pollerr, but other events too) could be acting on a freed up transport too.

* mempool: fix code when GF_DISABLE_MEMPOOL is definedNiels de Vos2017-09-021-3/+5
| | | | | | | | | | | | | | | | | | | | Problem: Run-time crash is observed when attempting to memset() a zero length buffer. Solution: When GF_DISABLE_MEMPOOL is set, mem_get() gets translated to a GF_MALLOC(). The size of the allocation does not need to relate to the available (but uninitialized) global memory pools. It is fine to allocate the exact amount of memory that was configured when the mem-pool was created.

| | | | | | | | | | | | | | | | | | | | In order to generate statedumps per glusterfs_ctx_t, it is needed to place all the memory pools in a structure that the context can reach. The 'struct mem_pool' has been extended with a 'list_head owner' that is linked with the glusterfs_ctx_t->mempool_list. All callers of mem_pool_new() have been updated to pass the current glusterfs_ctx_t along. This context is needed to add the new memory pool to the list and for grabbing the ctx->lock while updating the glusterfs_ctx_t->mempool_list.

GD2 does not use a hard-coded volume options map like GD1, but builds such by reading the options tables directly from the xlators. The new fields being introduced into the volume options struct include the following, - op-version - version(s) the option was introduced in - deprecated - version(s) the option was deprecated in - flags - flags for the option (settable, client, global, force, doc etc.) - tags - descriptive tags that apply to this option, can be used to group options - validate_fn - custom option validation function Enums for currently available flags have also been defined. To avoid a naming clashes, the flag enums in GD1 have been renamed.

| | | | | | | | | | | | | | | | | | | | | | | | This renames the current 'struct mem_pool' to 'struct mem_pool_shared'. The mem_pool_shared is globally allocated and not specific for particular objects. A new 'struct mem_pool' gets allocated when mem_pool_new() is called. It points to the mem_pool_shared that handles the actual allocation requests. The 'struct mem_pool' is only used for accounting of the objects that the caller requested and free'd. All of these changes will be used to collect all the memory pools a glusterfs_ctx_t is consuming, so that statedumps can be collected per context.
