* rpc: handle EAGAIN when SSL_ERROR_SYSCALL is returnedMilind Changire2018-09-211-2/+9
| | | | | | | | | | | | | | | | | Problem: A return value of ENODATA was forcibly returned in the case where SSL_get_error(r) returned SSL_ERROR_SYSCALL. Sometimes SSL_ERROR_SYSCALL is a transient error which is identified by setting errno to EAGAIN. EAGAIN is not a fatal error and indicates that the syscall needs to be retried. Solution: Bubble up the errno in case SSL_get_error(r) returns SSL_ERROR_SYSCALL and let the upper layers handle it appropriately. fixes: bz#1601356 Change-Id: I76eff278378930ee79abbf9fa267a7e77356eed6 Signed-off-by: Milind Changire <mchangir@redhat.com>

* rpc: set listen-backlog to high valueMilind Changire2018-04-131-1/+1
| | | | | | | | | | | | | | | | | | | | Problem: On node reboot, when glusterd starts volumes rapidly, there's a flood of connections from the bricks to glusterd and from the self-heal daemons to the bricks. This causes SYN Flooding and dropped connections when the listen-backlog is not enough to hold the pending connections to compensate for the rate at which connections are accepted by the RPC layer. Solution: Increase the listen-backlog value to 1024. This is a partial solution. Part of the solution is to rearm the listener socket early for quicker accept() of connections. See commit 6964640a977cb10c0c95a94e03c229918fa6eca8 (change 19833) Change-Id: I62283d1f4990dd43839f9a6932cf8a36effd632c fixes: bz#1564600 Signed-off-by: Milind Changire <mchangir@redhat.com>

| | | | | | | | | | | | | | | Problem: On node reboot, when glusterd starts volumes, a setup with a large number of bricks might cause SYN Flooding and connections to be dropped if the connections are not accepted quickly enough.

| | | | | | | | | | | | | | | | | | | | | Problem: TLS verification fails while using intermediate CA if mgmt SSL is enabled. Solution: There are two main issue of TLS verification failing 1) not calling ssl_api to set cert_depth 2) The current code does not allow to set certificate depth while MGMT SSL is enabled. After apply this patch to set certificate depth user need to set parameter option transport.socket.ssl-cert-depth <depth> in /var/lib/glusterd/secure_acccess instead to set in /etc/glusterfs/glusterd.vol. At the time of set secure_mgmt in ctx we will check the value of cert-depth and save the value of cert-depth in ctx.If user does not provide any value in cert-depth in that case it will consider default value is 1 BUG: 1555154 Change-Id: I89e9a9e1026e37efb5c20f9ec62b1989ef644f35 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

* build: address linkage issuesKaleb S. KEITHLEY2018-03-056-1/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | We have the following undefined symbol error from protocol/server.so: glusterfs_mgmt_pmap_signout glusterfs_autoscale_threads See https://review.gluster.org/19225 (bz#1532238) and https://review.gluster.org/19657 (bz#1550895) (why are there two different bzs for the same bug?) IMO this is a cleaner solution. I.e. moving the above two functions to libgfrpc (.../rpc/rpc-lib/...) I would also, for (foolish) consistency sake, like to see glusterfs_mgmt_pmap_signin() moved from glusterfsd to libgfrpc as well. This works on f28/rawhide, with its new, more restrictive run-time link semantics. The smoke and regression tests on earlier fedora and centos will confirm that it works on those platforms too.

| | | | | | | | | | | | | | | | | | | | | | With this patchset, some major things are changed in XDR, mainly: * Naming: Instead of gfs3/gfs4 settle for gfx_ for xdr structures * add iattx as a separate structure, and add conversion methods * the *_rsp structure is now changed, and is also reduced in number (ie, no need for different strucutes if it is similar to other response). * use proper XDR methods for sending dict on wire. Also, with the change of xdr structure, there are changes needed outside of xlator protocol layer to handle these properly. Mainly because the abstraction was broken to support 0-copy RDMA with payload for write and read FOP. This made transport layer know about the xdr payload, hence with the change of xdr payload structure, transport layer needed to know about the change.

* rpc: use export map to minimize exported symbols in libgf{rpc,xdr}.soKaleb S. KEITHLEY2018-01-124-3/+318
| | | | | | | | | | | | | | | | | | | | | | | | Without an export map (at link time) libgrpc and libgfxdr export over 150 and 450 symbols each, respectively. Many are not used by anything else. (Unclear what the unused symbols are, some may be simple sloppiness, e.g. not declaring functions static that should be. Others may be intra-library calls that can't be static but aren't part of the API, per se.) By linking with an export map the number of exported symbols is reduced to ~60 and ~250 respectively. This parallels the similar change made to libglusterfs recently and the older changes to the xlators to minimize the symbols that are visible (exported) from the .so. And I don't know, do we want to go all the way to symbol versions? For these libs?

* rpc-transport/rdma: Add a mutex for the list of RDMA Memory Region(MR) accessYi Wang2017-12-122-38/+72
| | | | | | | | | | | | | | | Problem: gf_rdma_device_t->all_mr is a __gf_rdma_arena_mr(includes MR content) kind of list in the rdma rpc-transport. The rdma rpc-transport will add/delete items to the list when MRs register, deregister, and free. Because gf_rdma_device_t->all_mr is used by different threads and it is not mutex protected, rdma transport maybe access obsolete items in it. Solution: Add a mutex protection for the gf_rdma_device_t->all_mr. Change-Id: I2b7de0f7aa516b90bb6f3c6aae3aadd23b243900 BUG: 1522651 Signed-off-by: Yi Wang <wangyi@storswift.com>

* rio/everywhere: add icreate/namelink fopSusant Palai2017-12-053-0/+31
| | | | | | | | | | | | | | | | | | | | | icreate creates inode, while namelink links the basename to it's parent gfid. For now mkdir is the primary user of these fops. Better distribution is acheived by creating the inode on ,(say) mds1 and linking the basename to it's parent gfid on mds2. The inode serves readdirp, stat etc. More details about the fops are present at: https://review.gluster.org/#/c/13395/3/design/DHT2/DHT2_Icreate_Namelink_Notes.md This backport of three patches from experimental branch. 1- https://review.gluster.org/#/c/18085/ 2- https://review.gluster.org/#/c/18086/ 3- https://review.gluster.org/#/c/18094/ Updates gluster/glusterfs#243 Change-Id: I1bd3d5a441a3cfab1acfeb52f15c6c867d362592 Signed-off-by: Susant Palai <spalai@redhat.com>
* libglusterfs: Add put fopPoornima G2017-12-051-0/+1
| | | | | | | | | | | | | | | | | Problem: It had been a longtime request to implement put fop in gluster. put fop in gluster may not have the exact sementics of HTTP PUT, but can be easily extended to do so. The subsequent patches, will contain more semantics on the put fop and its guarentees. Why compound fop framework is not used for put? Compound fop framework currently doesn't allow compounding of entry fop and inode fops, i.e. fops on multiple inodes cannot be combined in compound fop.

* rpc: Eliminate conn->lock contention by using more granular locksMohit Agrawal2017-11-283-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | | rpc_clnt_submit() acquires conn->lock before call to rpc_transport_submit_request() and subsequent queuing of frame into saved_frames list. However, as part of handling RPC_TRANSPORT_MSG_RECEIVED and RPC_TRANSPORT_MSG_SENT notifications in rpc_clnt_notify(), conn->lock is again used to atomically update conn->last_received and conn->last_sent event timestamps. So when conn->lock is acquired as part of submitting a request, a parallel POLLIN notification gets blocked at rpc layer until the request submission completes and the lock is released. To get around this, this patch call clock_gettime (instead to call gettimeofday) to update event timestamps in conn->last_received and conn->last_sent and to call clock_gettime don't need to call mutex_lock because it (clock_gettime) is thread safe call. Note: Run fio on vm after apply the patch, iops is improved after apply the patch.

* rpc : Change the way client uuid is builtPoornima G2017-11-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Today the main users of client uuid are protocol layers, locks, leases. Protocol layers requires each client uuid to be unique, even across connects and disconnects. Locks and leases on the server side also use the same client uid which changes across file migrations. Which makes the graph switch and file migration tedious for locks and leases. file migration across bricks becomes difficult as client uuid for the same client, is different on the other brick. The exact set of issues exists for leases as well. Solution would be to introduce a constant in the client-uid string which the locks and leases can use to identify the owner client across bricks. Client uuid currently: %s(ctx uuid)-%s(protocol client name)-%d(graph id)%s(setvolume count/reconnect count) Proposed Client uuid: "CTX_ID:%s-GRAPH_ID:%d-PID:%d-HOST:%s-PC_NAME:%s-RECON_NO:%s" - CTX_ID: This is will be constant per client. - GRAPH_ID, PID, HOST, PC_NAME(protocol client name), RECON_NO(setvolume count) remains the same.
