April 2024 - Devel - Nfs Ganesha List Archives

by gaurav gangalwar

Hello, We are planning to enable support for NFS over RDMA in Ganesha. There is some existing implementation in tirpc layer for RDMA, which was not in working state and not maintained any more. We spent some time to fix this code and add missing functionalities as mentioned below, Issue that we found and fixed: 1. Connection management issues connect and disconnect paths. (Fixed) 2. Static buffer management, can't scale. (Fixed) 3. Functional issues due not compliance with RPC over RDMA RFC. (Fixed) 4. Synchronous callbacks. (Not fixed) 5. Protocol buffer changes for read/readdir. (Fixed) 6. NFSv4 referral. (Client side issue, fixed in latest kernels) 7. Callback channels using RDMA clnt. (Not fixed) 8. ib verbs apis ibv_post_send. (Are there any issues with ib verbs apis?) 9. Srq changes. (Not fixed) 10. Single completion queue manager thread for all connections. (Not fixed) 11. Per connection buffer management (Nit fixed) We are planning to discuss it in a Ganesha community call (Tuesday, April 23rd 2024, 7.30 PM - 8.30 PM IST) Looking for any suggestions/feedback if anyone has tried it or has expertise in this area. Regards, Gaurav Gangalwar

[M] Change in ...nfs-ganesha[next]: Handle parallel delegation recalls for the same fsal_objs

by Rojin George (GerritHub)

Rojin George has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1193683?usp=email ) Change subject: Handle parallel delegation recalls for the same fsal_objs ...................................................................... Handle parallel delegation recalls for the same fsal_objs There were multiple delegation recalls happening for the same obj. The first thread enters with state lock to recall, once found that it could expire off the client which has gone inactive, we were releasing the state lock and setting DELEG_GRANTED for the state->state_data.deleg.sd_state, before actually expiring the client. This opens up window to the contending async task to acquire the same state lock and crash off, as it started dereferencing the clientid related structures which would have gone stale, as part of the first threads client expire path. This CR avoids such contenders by just cleaning the conflciting state off the expired client to revoke the delegation and if lease reservation fails then we set the state to DELEG_GRANTED so that reaper would be able to clean up the states associated with the expired clients properly.
