* dict: use the free_pair's key presence or NULL as a sign of use.Yaniv Kaul2020-01-132-18/+15
| | | | | | | | | | | | | Instead of using a boolean parameter, we can use the key variable. If it's NULL, the pair is not used and can be used. Otherwise, it's in use - don't use. It saves this annoying boolean, which causes the compiler (or us explicitly) to pad with additional bytes the dict struct.

* Avoid buffer overwrite due to uuid_utoa() misuseDmitry Antipov2019-12-271-5/+7
| | | | | | | | | | | | | | | Code like: f(..., uuid_utoa(x), uuid_utoa(y)); is not valid (causes undefined behaviour) because uuid_utoa() uses the only static thread-local buffer which will be overwritten by the subsequent call. All such cases should be converted to use uuid_utoa_r() with explicitly specified buffer.

* timer: fix event destruction raceXavi Hernandez2019-12-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current timer implementation, each event has an absolute time at which it will be fired. When the first timer of the queue has not elapsed yet, a pthread_cond_timedwait() is used to wait until the expected time. Apparently that's fine. However the time passed to that function was a pointer to the timespec structure contained in the event itself. This is problematic because of how pthread_cond_timedwait() works internally. Simplifying a bit, pthread_cond_timedwait() basically queues itself as a waiter for the given condition variable and releases the mutex. Then it does the timed wait using the passed value. With that in mind, the follwing case is possible: Timer Thread Other Thread ------------ ------------ gf_timer_call_cancel() pthread_mutex_lock() | + pthread_mutex_lock() event = current_event() | pthread_cond_timedwait(&event->at) | + pthread_mutex_unlock() | | + remove_event() | + destroy_event() + timed_wait(&event->at) As we can see, the time is used after it has been destroyed, which means we have a use-after-free problem. This patch fixes the problem by copying the time to a local variable before calling pthread_cond_timedwait() Change-Id: I0f4e8eded24fe3a1276dc75c6cf093bae973d26b Signed-off-by: Xavi Hernandez <xhernandez@redhat.com> Fixes: bz#1785208
* Revert "store.c: remove a sys_stat() call - just open the file"Sanju Rakonde2019-12-251-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit da735ad9b58b76d27c580a9feb63f14b2cc0669d. This commit is changing the behaviour of glusterd during its initialization. The removed piece of code checks whether the file mentioned in the path exists or not, if not it returns -1. This return value is considered for the sub sequent operations. By removing this code, we always return 0 and some part of the code will not be executed in the following code path. glusterd_options_init() -> glusterd_store_retrieve_options() -> gf_store_handle_retrieve() In glusterd_options_init(), we are not executing any code if the ret value is 0. ret = glusterd_store_retrieve_options(this); if (ret == 0) { goto out; } as we are not executing any code if the return value is 0, we are unable to enable the brick-multiplex feature using volume set. fixes: bz#1786459 Change-Id: I4f52b7b2ea8adb8df5087bb96927e9bb7db5b491

* ctime: Fix ctime inconsisteny with utimensatKotresh HR2019-12-101-0/+2
| | | | | | | | | | | | | | | | | | | | Problem: When touch is used to create a file, the ctime is not matching atime and mtime which ideally should match. There is a difference in nano seconds. Cause: When touch is used modify atime or mtime to current time (UTIME_NOW), the current time is taken from kernel. The ctime gets updated to current time when atime or mtime is updated. But the current time to update ctime is taken from utime xlator. Hence the difference in nano seconds. Fix: When utimesat uses UTIME_NOW, use the current time from kernel. fixes: bz#1773530 Change-Id: I9ccfa47dcd39df23396852b4216f1773c49250ce Signed-off-by: Kotresh HR <khiremat@redhat.com>

* common-utils.c: add gf_strn2boolean() functionYaniv Kaul2019-11-273-1/+71
| | | | | | | | | | | | | | | | | | | | | The function takes a string and its length and based on it returns if it's a boolean. It's identical in functionality to gf_string2boolean only with far less string comparisons since it takes into account the length of the string. dict_get_str_boolean() has been converted to use it. Other cases of gf_string2boolean() across the code base can be converted as well, but more importantly, they should be converted from dict_get_str() and then calling to gf_string2boolean to simply call dict_get_str_boolean(), which would take care of this for them. This is therefore a first step in the conversion. Change-Id: I9ee93abfc676f6e123a3919d8df8c25e8848b799 updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com>

| | | | | | | | | | | | | | | Instead of querying for the file size and allocating a char array according to its size, let's just use a fixed size. Those calls are not really needed, and are either expensive or cached anyway. Since we do dynamic allocation/free, let's just use a fixed array instead. I'll see if there are other sys_stat() calls that are not really useful and try to eliminate them in separate patches.

* protocol/handshake: pass volume-id for extra checkAmar Tumballi2019-09-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With added check of volume-id during handshake, we can be sure to not connect with a brick if this gets re-used in another volume. This prevents any accidental issues which can happen with a stale client process lurking along. Also added test case for testing same volume name which would fetch a different volfile (ie, different bricks, different type), and a different volume name, but same brick. For reference: Currently a client<->server handshake happens in glusterfs through protocol/client translator (setvolume) to protocol/server using a dictionary which containes many keys. Rejection happens in server side if some of the required keys are missing in handshake dictionary. Till now, there was no single unique identifier to validate for a client to tell server if it is actually talking to a corresponding server. All we look in protocol/client is a key called 'remote-subvolume', which should match with a subvolume name in server volume file, and for any volume with same brick name (can be present in same cluster due to recreate), it would be same. This could cause major issue, when a client was connected to a given brick, in one volume would be connected to another volume's brick if its re-created/re-used. To prevent this behavior, we are now passing along 'volume-id' in handshake, which would be preserved for the life of client process, which can prevent this accidental connections. NOTE: This behavior wouldn't be applicable for user-snapshot enabled volumes, as snapshotted volume's would have different volume-id.

But this is prone to race condition when some of the bricks are already disconnected. In this case, even before the last child down is executed in the client xlator code,we might have freed the graph. Because the child_down event is alreadt recevied. To fix this race, we have introduced a check to see if all client xlator have cleared thier reconnect chain, and called the child_down for last time.

Convert values into fields and add any missing fields. Note: `errno` and `error` fields will be added automatically to log message in case errnum is specified. Example: gf_smsg( this->name, // Name or log domain GF_LOG_WARNING, // Log Level rsp.op_errno, // Error number PC_MSG_REMOTE_OP_FAILED, // Message ID "path=%s", local->loc.path, // Key Value 1 "gfid=%s", loc_gfid_utoa(&local->loc), // Key Value 2 NULL // Log End ); Key value pairs formatting Help: gf_slog( this->name, // Name or log domain GF_LOG_WARNING, // Log Level rsp.op_errno, // Error number PC_MSG_REMOTE_OP_FAILED, // Message ID "op=CREATE", // Static Key and Value "path=%s", local->loc.path, // Format for Value "brick-%d-status=%s", brkidx, brkstatus, // Use format for key and val NULL // Log End ); Before: [2019-07-03 08:16:18.226819] W [MSGID: 114031] [client-rpc-fops_v2.c \ :2633:client4_0_lookup_cbk] 0-gv3-client-0: remote operation failed. \ Path: / (00000000-0000-0000-0000-000000000001) [Transport endpoint \ is not connected] After: [2019-07-29 07:50:15.773765] W [MSGID: 114031] \ [client-rpc-fops_v2.c:2633:client4_0_lookup_cbk] 0-gv1-client-0: \ remote operation failed.

* posix: In brick_mux brick is crashed while start/stop volume in loopMohit Agrawal2019-08-201-0/+3
| | | | | | | | | | | | | | | Problem: In brick_mux environment sometime brick is crashed while volume stop/start in a loop.Brick is crashed in janitor task at the time of accessing priv.If posix priv is cleaned up before call janitor task then janitor task is crashed. Solution: To avoid the crash in brick_mux environment introduce a new flag janitor_task_stop in posix_private and before send CHILD_DOWN event wait for update the flag by janitor_task_done Change-Id: Id9fa5d183a463b2b682774ab5cb9868357d139a4 fixes: bz#1730409 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>

* libglusterfs: remove dependency of rpcAmar Tumballi2019-08-166-96/+24
| | | | | | | | | | | | | | | | | | Goal: 'libglusterfs' files shouldn't have any dependency outside of the tree, specially the header files, shouldn't have '#include' from outside the tree. Fixes: * Had to introduce libglusterd so, methods and structures required for only mgmt/glusterd, and cli/ are separated from 'libglusterfs/' * Remove rpc/xdr/gen from build, which was used mainly so dependency for libglusterfs could be properly satisfied. * Move rpcsvc_auth_data to client_t.h, so all dependencies could be handled.

* fuse: Set limit on invalidate queue sizeN Balachandran2019-08-143-8/+25
| | | | | | | | | | | | | If the glusterfs fuse client process is unable to process the invalidate requests quickly enough, the number of such requests quickly grows large enough to use a significant amount of memory. We are now introducing another option to set an upper limit on these to prevent runaway memory usage.

* event: rename event_XXX with gf_ prefixedXiubo Li2019-07-293-40/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I hit one crash issue when using the libgfapi. In the libgfapi it will call glfs_poller() --> event_dispatch() in file api/src/glfs.c:721, and the event_dispatch() is defined by libgluster locally, the problem is the name of event_dispatch() is the extremly the same with the one from libevent package form the OS. For example, if a executable program Foo, which will also use and link the libevent and the libgfapi at the same time, I can hit the crash, like: kernel: glfs_glfspoll[68486]: segfault at 1c0 ip 00007fef006fd2b8 sp 00007feeeaffce30 error 4 in libevent-2.0.so.5.1.9[7fef006ed000+46000] The link for Foo is: lib_foo_LADD = -levent $(GFAPI_LIBS) It will crash. This is because the glfs_poller() is calling the event_dispatch() from the libevent, not the libglsuter. The gfapi link info : GFAPI_LIBS = -lacl -lgfapi -lglusterfs -lgfrpc -lgfxdr -luuid If I link Foo like: lib_foo_LADD = $(GFAPI_LIBS) -levent It will works well without any problem. And if Foo call one private lib, such as handler_glfs.so, and the handler_glfs.so will link the GFAPI_LIBS directly, while the Foo won't and it will dlopen(handler_glfs.so), then the crash will be hit everytime. The link info will be: foo_LADD = -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) I can avoid the crash temporarily by linking the GFAPI_LIBS in Foo too like: foo_LADD = $(GFAPI_LIBS) -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) But this is ugly since the Foo won't use any APIs from the GFAPI_LIBS. And in some cases when the --as-needed link option is added(on many dists it is added as default), then the crash is back again, the above workaround won't work.
