* bitrot: Make number of signer threads configurableKotresh HR2020-02-071-0/+1
| | | | | | | | | | | | | The number of signing process threads (glfs_brpobj) is set to 4 by default. The recommendation is to set it to number of cores available. This patch makes it configurable as follows gluster vol bitrot <volname> signer-threads <count> fixes: bz#1797869 Change-Id: Ia883b3e5e34e0bc8d095243508d320c9c9c58adc Signed-off-by: Kotresh HR <khiremat@redhat.com>

* dictionary: remove the 'extra_free' parameterYaniv Kaul2020-01-212-2/+0
| | | | | | | | | | | | | | | This parameter may have been used in the past, but is no longer needed. Removing it and the few locations it was actually referenced. This allows to remove an extra memdup as well, that was not needed in the 1st place in server_setvolume() and unserialize_rsp_direntp() functions. A followup separate patch will remove extra_stdfree parmeter from the dictionary structure.

* 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.

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

* 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>

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.

* graph/cleanup: Fix race in graph cleanupMohammed Rafi KC2019-09-056-2/+33
| | | | | | | | | | | | | | | | | We were unconditionally cleaning up the grap when we get child_down followed by parent_down. 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.

* ctime: Fix incorrect realtime passed to frame->root->ctimeKotresh HR2019-08-223-0/+25
| | | | | | | | | | | | On systems that don't support "timespec_get"(e.g., centos6), it was using "clock_gettime" with "CLOCK_MONOTONIC" to get unix epoch time which is incorrect. This patch introduces "timespec_now_realtime" which uses "clock_gettime" with "CLOCK_REALTIME" which fixes the issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To convert the existing `gf_msg` to `gf_smsg`: - Define `_STR` of respective Message ID as below(In `*-messages.h`) #define PC_MSG_REMOTE_OP_FAILED_STR "remote operation failed." - Change `gf_msg` to use `gf_smsg`. 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.
