* core: avoid dynamic TLS allocation when possibleXavi Hernandez2019-04-241-5/+1
| | | | | | | | | | | | | | | | | | | Some interdependencies between logging and memory management functions make it impossible to use the logging framework before initializing memory subsystem because they both depend on Thread Local Storage allocated through pthread_key_create() during initialization. This causes a crash when we try to log something very early in the initialization phase. To prevent this, several dynamically allocated TLS structures have been replaced by static TLS reserved at compile time using '__thread' keyword. This also reduces the number of error sources, making initialization simpler.

* rpc/transport: Missing a ref on dict while creating transport objectMohammed Rafi KC2019-03-203-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | while creating rpc_tranpsort object, we store a dictionary without taking a ref on dict but it does an unref during the cleaning of the transport object. So the rpc layer expect the caller to take a ref on the dictionary before passing dict to rpc layer. This leads to a lot of confusion across the code base and leads to ref leaks. Semantically, this is not correct. It is the rpc layer responsibility to take a ref when storing it, and free during the cleanup. I'm listing down the total issues or leaks across the code base because of this confusion. These issues are currently present in the upstream master. 1) changelog_rpc_client_init 2) quota_enforcer_init 3) rpcsvc_create_listeners : when there are two transport, like tcp,rdma. 4) quotad_aggregator_init 5) glusterd: init 6) nfs3_init_state 7) server: init 8) client:init This patch does the cleanup according to the semantics.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-0533-106/+106
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* build: cleanup xlator link, --no-undefined, libuuidv6devKaleb S. KEITHLEY2018-09-121-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While attempting to build a (pre-)5.0 of glusterfs on Ubuntu bionic and cosmic, it became apparent that there are some gremlins hiding in the combination of the xlator export-symbols, the newish addition of -Wl,--no-undefined, and the new switch to libuuid from the old contrib/uuid. Note: even though Fedora 28 (and later) and Ubuntu bionic (and later) have the same nominal version of libtool, the Fedora version appears to do a better job of recursing through dependencies to determine the libraries to link with. Examination of the build logs showed that despite appearing to work on Fedora, not all xlators and shared libs were linked with -Wl, --no-undefined, and -luuid. And in the case of the gnfs xlator, it was not only not linked with -Wl,--no-undefined but alsos not linked with -lgfxdr and -lgfrpc. Added GF_XLATOR_LDFLAGS, similar to GF_XLATOR_DEFAULT_LDFLAGS. GF_XLATOR_DEFAULT_LDFLAGS is for xlators that export/expose the default or common set of symbols. GF_XLATOR_LDFLAGS is for those remaining xlators that export/expose non-default symbols, e.g. dht and glupy. This removes the need in the future to add things like $(UUID_LIBS) to every xlator's Makefile.am. Just add it to GF_XLATOR_LDFLAGS and GF_XLATOR_DEFAULT_LDFLAGS in configure.ac and you're done. This patch was tested on Fedora 28 (build, rpmbuild), Fedora Rawhide/30 (rpmbuild), RHEL8 (rpmbuild), CentOS7 (rpmbuild), Fedora koji --scratch build for f30/rawhide, and a Launchpad build for Ubuntu cosmic/18.10.

* glusterd: volume inode/fd status broken with brick muxhari gowtham2018-04-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Problem: The values for inode/fd was populated from the ctx received from the server xlator. Without brickmux, every brick from a volume belonged to a single brick from the volume. So searching the server and populating it worked. With brickmux, a number of bricks can be confined to a single process. These bricks can be from different volumes too (if we use the max-bricks-per-process option). If they are from different volumes, using the server xlator to populate causes problem. Fix: Use the brick to validate and populate the inode/fd status.

Building RPMs can pass `--without server` and the glusterfs-server sub-package will not be created.

| | | | | | | | | | | | | | | | | | v1 of the patch started off as adding new fields to iatt that can be filled up using statx but the discussions were more around introducing masks to check the validity of different fields from a RIO perspective. To that extent, I have dropped the statx call in this version and introduced a 64 bit mask for existing fields. The masks I have defined are similar with the statx() flags' masks. I have *not* changed iatt_to_stat() to use the macros IATT_TYPE_VALID, IATT_GFID_VALID etc before blindly copying from struct iatt to struct. Also fixed warnings in xlators because of atime/mtime/ctime seconds field change from uint32_t to int64_t.

Solution: There is no need to use mutex to increase/decrease ref counter, instead of using mutex use gcc builtin ATOMIC operation. Test: I have not observed yet how much performance gain after apply this patch specific to glusterfs but i have tested same with below small program(mutex and atomic both) and get good difference. static int numOuterLoops; static void * threadFunc(void *arg) { int j; for (j = 0; j < numOuterLoops; j++) { __atomic_add_fetch (&glob, 1,__ATOMIC_ACQ_REL); } return NULL; } int main(int argc, char *argv[]) { int opt, s, j; int numThreads; pthread_t *thread; int verbose; int64_t n = 0; if (argc < 2 ) { printf(" Please provide 2 args Num of threads && Outer Loop\n"); exit (-1); } numThreads = atoi(argv[1]); numOuterLoops = atoi (argv[2]); if (1) { printf("\tthreads: %d; outer loops: %d;\n", numThreads, numOuterLoops); } thread = calloc(numThreads, sizeof(pthread_t)); if (thread == NULL) { printf ("calloc error so exit\n"); exit (-1); } __atomic_store (&glob, &n, __ATOMIC_RELEASE); for (j = 0; j < numThreads; j++) { s = pthread_create(&thread[j], NULL, threadFunc, NULL); if (s != 0) { printf ("pthread_create failed so exit\n"); exit (-1); } } for (j = 0; j < numThreads; j++) { s = pthread_join(thread[j], NULL); if (s != 0) { printf ("pthread_join failed so exit\n"); exit (-1); } } printf("glob value is %ld\n",__atomic_load_n (&glob,__ATOMIC_RELAXED)); exit(0); } time ./thr_count 800 800000 threads: 800; outer loops: 800000; glob value is 640000000 real 1m10.288s user 0m57.269s sys 3m31.565s time ./thr_count_atomic 800 800000 threads: 800; outer loops: 800000; glob value is 640000000 real 0m20.313s user 1m20.558s sys 0m0.028 Change-Id: Ie5030a52ea264875e002e108dd4b207b15ab7cc7 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

| | | | | | | | | | | | | | | | | | | | 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.

* nfs: use "/" as subdir for volume mountsNiels de Vos2017-08-011-17/+14
| | | | | | | | | | | | | | | | | | | | | | For cases where subdir mounting is checked, it makes it much easier to return a subdir of "/" in case no subdir is passed. This reduces the number of corner cases where permissions are checked for subdir mounts, but not for volume mounts (or the other way around). The problem was identified by WebNFS mounting a volume, which got denied after commit e3f48fa2. Handling this would require an exception for non-subdir mounts, or make non-subdir mounts equal to subdir mounts. This change takes the 2nd approach.

* nfs: add permission checking for mounting over WebNFSNiels de Vos2017-07-094-62/+99
| | | | | | | | | | | | | | | | | | | | | | | Solaris 10 uses WebNFS and not the MOUNT protocol. All permission checks for allowing/denying clients to mount are done through the MNT handlers. These handlers will not give out a filehandle to the NFS-client when mounting is denied. This prevents clients from successful mounting. However, over WebNFS a well known 'root-filehandle' is used directly with the NFSv3 protocol. When WebNFS was used, no permission checks (the "nfs.export-dir" option) were applied. Now the WebNFS mount-handler in Gluster/NFS calls the mnt3_parse_dir_exports() function that takes care of the permission checking.
