* protocol: Fix 4.0 client, parsing older iatt in dictShyamsundarR2018-03-101-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | In a mixed mode cluster involving 4.0 and older 3.x bricks, if clients are newer, then the iatt encoded in the dictionary can be of the older iatt format, which a newer client will map incorrectly to the newer structure. This causes failures in FOPs that depend on this iatt for some functionality (seen in mkdir operations failing as EIO, when DHT hits its internal setxattr call). The fix provided is to convert the iatt in the dict, based on which RPC version is used to communicate with the server. IOW, this is the reverse of change in commit "b966c7790e" Tested using a mixed mode cluster (i.e bricks in 3.12 and 4.0 versions) and a mixed set of clients, 3.12 and 4.0 clients. There is no regression test provided, as this needs a mixed mode cluster to test and validate.

* protocol: make on-wire-change of protocol using new XDR definition.Amar Tumballi2018-01-191-0/+1441
| | | | | | | | | | | | | | | | | | | | | | 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.

* afr, client: More mem-leak fixes in COMPOUND fop cbkKrutika Dhananjay2016-12-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | Bugs found and fixed: 1. Use correct subvolume index in pre-op-writev compound cbk 2. Prevent use-after-free of local->compound_args members in compound fops cbk in protocol/client 3. Fix xdata and xattr leaks in client_process_response 4. Fix possible leak of xdata in client_pre_writev() in test mode. 5. Free req->compound_req_array.compound_req_array_val as well after freeing its members 6. Free tmp_rsp->flock.lk_owner.lk_owner_val in LK fop.

* protocol/client: Unserialize xdata even if lookup failsAnuradha Talur2016-08-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: AFR relies on xdata returned by lookup to determine if there are any files that need healing. This info is further used to optimize readdirp. In case of lookups with negative return value, client xlator was sending NULL xdata. Due to absence of xdata, AFR conservatively assumes that there are files that need healing, which is incorrect. Solution: Even in case of unsuccessful lookups, send the xdata received by protocol client so that higher xlators can get the info that they rely on.
