* core/memacct: save allocs in mem_acct_rec listN Balachandran2017-12-071-1/+33
| | | | | | | | | | | | | | | With configure --enable-debug, add all object allocations to a list in the corresponding mem_acct_rec. This allows us to see all objects of a particular type and allows for additional debugging in case of memory leaks. This is not compiled in by default and must be explicitly enabled. It is intended to be used by developers. Change-Id: I7cf2dbeadecf994423d7e7591e85f18d2575cce8 BUG: 1522662 Signed-off-by: N Balachandran <nbalacha@redhat.com>

* 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.

* mem-pool: track glusterfs_ctx_t in struct mem_poolNiels de Vos2017-08-291-1/+17
| | | | | | | | | | | | | | | | | | | | 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.

* mem-pool: add tracking of mem_pool that requested the allocationNiels de Vos2017-08-281-28/+32
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* mem-pool: track and verify initialization stateNiels de Vos2017-07-281-8/+32
| | | | | | | | | | | | | | | | | | | | | | | | | It is possible that pthread_getspecific() returns a non-NULL value in case the pthread_key_t is not initialized. The behaviour for pthread_getspecific() is not defined in this case. This can happen when applications use mem-pools from libglusterfs.so, but did not call mem_pools_init_early(). By tracking the status of the mem-pools initialization, it is now possible to prevent calling pthread_getspecific() in case the pthread_key_t is not initialized. In future, we might want to exend this more to faciliate debugging.

* mem-pool: free objects from pools on mem_pools_fini()Niels de Vos2017-07-201-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a minimal gfapi application that only initializes a small graph (sink, shard and meta xlators) the following memory leaks are reported by Valgrind: HEAP SUMMARY: in use at exit: 322,976 bytes in 75 blocks total heap usage: 684 allocs, 609 frees, 2,092,116 bytes allocated With this change, the mem-pools are cleaned up on calling of mem_pools_fini() and the objects in the pool are free'd. HEAP SUMMARY: in use at exit: 315,265 bytes in 58 blocks total heap usage: 684 allocs, 626 frees, 2,092,079 bytes allocated This information was gathered with `./run-xlator.sh features/shard` that comes with `gfapi-load-volfile` from gluster-debug-tools. While working on the free'ing of the per_thread_pool_list_t structures, it became apparent that GF_CALLOC() in mem_get_pool_list() gets redirected to a standard calloc() without prepending the Gluster specific memory header. This is because mem_pools_init() gets called before THIS->ctx is valid, so it is not possible to check if memory accounting is enabled or not. Because of this, the GF_CALLOC() call in mem_get_pool_list() has been replaced by CALLOC() to prevent potential mismatches between the allocation/free'ing of per_thread_pool_list_t structures.

* mem-pool: initialize pthread_key_t pool_key in mem_pool_init_early()Niels de Vos2017-07-191-14/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

There are at least two issues with this approach: 1. this lock is unused on architectures that have atomic operations 2. some structures use a single lock for multiple variables By defining a gf_atomic_t type, the unused lock can be removed, saving a few bytes on modern architectures. Because the gf_atomic_t type locates the lock for the variable (in case of older architectures), each variable is protected the same on all architectures. This makes the behaviour across all architectures more equal (per variable locking, by a gf_lock_t or compiler optimization).

* libglusterfs: make memory pools more thread-friendlyJeff Darcy2017-02-021-221/+303
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* libglusterfs: add gf_get_mem_type()Niels de Vos2016-08-151-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | gfapi needs to provide a function towards applications to free memory that it allocated. Depending on how the application is compiled/linked, it could use a different memory allocator than Gluster itself. Therefore it is not safe for gfapi to request applications to free memory with 'standard' free(). Examples for this are Gluster allocated structures with GF_CALLOC() when memory accounting is enabled (the default). Some gfapi functions use malloc() to allocate memory as a workaround, but the free() from the jemalloc implementation should not be combined with the malloc() from glibc.

* core: use reference counting for mem_acct structuresJeff Darcy2015-05-091-42/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When freeing memory, our memory-accounting code expects to be able to dereference from the (previously) allocated block to its owning translator. However, as we have already found once in option validation and twice in logging, that translator might itself have been freed and the dereference attempt causes on of our daemons to crash with SIGSEGV. This patch attempts to fix that as follows: * We no longer embed a struct mem_acct directly in a struct xlator, but instead allocate it separately. * Allocated memory blocks now contain a pointer to the mem_acct instead of the xlator. * The mem_acct structure contains a reference count, manipulated in both the normal and translator allocate/free code using atomic increments and decrements. * Because it's now a separate structure, we can defer freeing the mem_acct until its reference count reaches zero (either way). * Some unit tests were disabled, because they embedded their own copies of the implementation for what they were supposedly testing. Life's too short to spend time fixing tests that seem designed to impede progress by requiring a certain implementation as well as behavior.

| | | | | | | | | | | | | | | | | | | | | | | | Debugging where memory gets free'd with help from overwriting the memory before it is free'd with some structures (repeatedly). The struct mem_invalid starts with a magic value (0xdeadc0de), followed by a pointer to the xlator, the mem-type. the size of the GF_?ALLOC() requested area and the baseaddr pointer to what GF_?ALLOC() returned. With these details, and the 'struct mem_header' that is placed when calling GF_?ALLOC(), it is possible to identify overruns and possible use-after-free. A memory dump (core) or running with a debugger is needed to read the surrounding memory of corrupt structures. This additional memory invalidation/poisoning needs to be enabled by passing --enable-debug to ./configure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although glusterd currently has statedump support but it doesn't dump its context information. Implementing glusterd_dump_priv function to export per-node glusterd information would be useful for debugging bugs. Once implemented, we could enhance sos-report to fetch this information. This would potentially reduce our time to root cause and data needed for debugability can be dumped gradually. Following is the main items of the dump list targeted in this patch : * Supported max/min op-version and current op-version * Information about peer list * Information about peer list involved while a transaction is going on (xaction_peers) * option dictionary in glusterd_conf_t * mgmt_v3_lock in glusterd_conf_t * List of connected clients * uuid of glusterd * A section of rpc related information like live connections and their statistics There are couple of issues which were found during implementation and testing phase: - xaction_peers of glusterd_conf_t was not initialized in init because of which traversing through this list head was crashing when there was no active transaction - gf_free was not setting the typestr to NULL if the the alloc count becomes 0 for a mem-type earlier allocated.

* log: enhance gluster log format with message ID and standardize errno reportingShyamsundarR2014-03-281-3/+3

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>

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).

| | | | | | | | | | | | | | | | | | currently this is implemented as a command line option, and not as an easier translator option. this is because as of now, before even the volume files are parsed, we would need memory accounting enabled. there is scope for improving this behavior, but for now, this approach solves the problem. Also, this feature's major consumers are the testers who are looking for leaks, hence option is hidden from usage output.

Understanding more about those numbers will help us to tune mempool parameters properly over time.

* core: utilize mempool for frame->local allocationsAmar Tumballi2012-02-211-3/+3
| | | | | | | | | | | | | | | in each translator, which uses 'frame->local', we are using GF_CALLOC/GF_FREE, which would be costly considering the number of allocation happening in a lifetime of 'fop'. It would be good to utilize the mem pool framework for xlator's local structures, so there is no allocation overhead.
