* io-cache: xdata needs to be passed for readv operationsSoumya Koduri2018-12-042-2/+16
| | | | | | | | | | | | io-cache xlator has been skipping xdata references when the date needs to be read into page cache. This patch fixes the same. Note: similar changes may be needed for other fops as well which are handled by io-cache.

* rpc: check if fini is there before calling itRaghavendra Bhat2018-12-041-1/+3
| | | | | | | | | | | | | | | The rpc_transport_t structure is allocated and filled in the rpc_transport_load function. If filling the fileds of the rpc structure fails, then in the failure handling the structure is freed by rpc_transport_cleanup. There, it unconditionally calls fini. But, if the failure handling was invoked because of any failure in between the allocation of rpc_transport_t and filling the transport->fini (including the failure to fill fini ()), then rpc_transport_cleanup can lead to a segfault.

* glusterd: perform rcu_read_lock/unlock() under cleanup_lock mutexSanju Rakonde2018-12-0316-199/+213
| | | | | | | | | | | | | | Problem: glusterd should not try to acquire locks on any resources, when it already received a SIGTERM and cleanup is started. Otherwise we might hit segfault, since the thread which is going through cleanup path will be freeing up the resouces and some other thread might be trying to acquire locks on freed resources. Solution: perform rcu_read_lock/unlock() under cleanup_lock mutex. fixes: bz#1654270 Change-Id: I87a97cfe4f272f74f246d688660934638911ce54 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* features/bitrot: compare the signature with proper lengthRaghavendra Bhat2018-12-032-8/+14
| | | | | | | | | | | | | | | | | | | | | * The scrubber was comparing the checksum of the file that it calculated (by reading the file) with the on disk signature (stored via xattr) wrongly. It was using strlen to calculate the signature, while the actual length of the signature is given by the brick. Just use the actual length that the brick provides instead of trying to calculate the signature length via strlen API. * In posix, gfid2path was using the same string that contains the list of all the xattrs of file to save the value of the gfid2path xattr as well. This causes confusion when gfid2path xattr is queried by scrubber for getting the actual path of a corrupted file. Use separate string to fetch the value of the xattr instead of the string that contains the list of xattrs.

Hence no need to recall Lease for such fops. Note: Like for locks, we would need rebalance and self-heal daemon process to heal lease state as well.

* clang: Fix clang warnings in snapview-server.cShyamsundarR2018-11-291-12/+0
| | | | | | | | | | | | | | | | | | | | | The warning by clang is due to the fact that we check for frame->root to be NULL, but in stack unwind, we ignore the same. If frame is non-NULL then frame->root is non-NULL as frame creation ensures this. Further, across the code we do not check both frame and frame->root for validity. Hence to fix these clang issues, removing the check for frame->root in the various functions. NOTE: Initially clang reported 14 issues in the file, but post commit 6eabefe6 the number reduced to 4, unsure why as that commit does not address this issue.

* libglusterfs: fix memory corruption caused by per-thread mem poolsXavi Hernandez2018-11-261-57/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a race in the per-thread memory pool management that could lead to memory corruption. The race appeared when the following sequence of events happened: 1. Thread T1 allocated a memory object O1 from its own private pool P1 2. T1 terminates and P1 is marked to be destroyed 3. The mem-sweeper thread is woken up and scans all private pools 4. It detects that P1 needs to be destroyed and starts releasing the objects from hot and cold lists. 5. Thread T2 releases O1 6. O1 is added to the hot list of P1 The problem happens because steps 4 and 6 are protected by diferent locks, so they can run concurrently. This means that both T1 and T2 are modifying the same list at the same time, potentially causing corruption. This patch fixes the problem using the following approach: 1. When an object is released, it's only returned to the hot list of the corresponding memory pool if it's not marked to be destroyed. Otherwise the memory is released to the system. 2. Object release and mem-sweeper thread synchronize access to the deletion mark of the memory pool to prevent simultaneous access to the list. Some other minor adjustments are made to reduce the lengths of the locked regions.

* geo-rep: Fix permissions with non-root setupKotresh HR2018-11-261-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In non-root fail-over/fail-back(FO/FB), when slave is promoted as master, the session goes to 'Faulty' Cause: The command 'gluster-mountbroker <mountbroker-root> <group>' is run as a pre-requisite on slave in non-root setup. It modifies the permission and group of following required directories and files recursively [1] /var/lib/glusterd/geo-replication [2] /var/log/glusterfs/geo-replication-slaves In a normal setup, this is executed on slave node and hence doing it recursively is not an issue on [1]. But when original master becomes slave in non-root during FO/FB, it contains ssh public keys and modifying permissions on them causes geo-rep to fail with incorrect permissions.

* gfapi: Offload callback notifications to synctaskSoumya Koduri2018-11-264-10/+419
| | | | | | | | | | | | | | | | | | | | | | Upcall notifications are received from server via epoll and same thread is used to forward these notifications to the application. This may lead to deadlock and hang in the following scenario. Consider if as part of handling these callbacks, application has to do some operations which involve sending I/Os to gfapi stack which inturn have to wait for epoll threads to receive repsonse. Thus this may lead to deadlock if all the epoll threads are waiting to complete these callback notifications. To address it, instead of using epoll thread itself, make use of synctask to send those notificaitons to the application.

* Coverity fix for calling risky function - fscanfPoornima G2018-11-242-7/+7
| | | | | | | | | | | | | | | fscanf with %s reads a word, there is no restriction on the length of that word, and the caller is required to pass a sufficiently large buffer for storing thw word. If the input word exceeds the buffer size, it will cause buffer overflow. To fix this, use fscanf with width parameter. Width specifies the maximum number of characters to be read in the current reading operation.

* snapview-server: close the gfapi handle present in a forgotten inodeRaghavendra Bhat2018-11-201-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the snapdaemon can reach the lru limit of the inode table and start sending forgets on the inodes that are least recently used. snapview-server maintains the mapping between the domain of the snapdaemon and the gfapi instance which it uses to access the snapshots via a handle that is stored in the inode context of snapdaemon's inode. The handle is glfs_h_object structure which itself points to the actual inode present in the gfapi world. But, when snapview-server receives forget on a inode, it deleted the inode context without actually closing the handle it had obtained to map the inode from snapdaemon to the inode in gfapi world. So, this change makes sure that, the handle is closed as part of the inode forget. And this closure of the handle will result in gfapi world receiving forget and unref on its corresponding inode. But care must be taken to ensure before the closure to ensure that the gfapi instance from which the handle came from, is still valid and not destroyed. Otherwise, sending a forget downward to the gfapi world might result in the access of freed pointers. Hence, the snapview-server xlator first checks whether that gfapi instance is still there or not and then proceeds with closure of the handle.
