Failure in running smb2.multichannel tests #186

Open spuiuk opened 3 years ago

spuiuk commented 3 years ago

There appears to be problem with setting up iptable rules and the issue is meant to track the investigation into this.

Could these issues be related to some more generic firewall issues we were encountering elsewhere?

spuiuk commented 3 years ago

The following tests fail along with the reasons for their failure.

smb2.multichannel.oplocks.test2 - multichannel.c: 734 - request for a batch oplock and get one. This causes failure. smb2.multichannel.oplocks.test3_windows - same

smb2.multichannel.oplocks.test3_specification - Port blocked and oplock request is therefore not delivered. However the server doesn't appear to retry the oplock break and instead responds to the create call within a second.

smb2.multichannel.leases.test2 - multichannel.c:1653 Check the lease set when new file created. Expected RH but received RWH smb2.multichannel.leases.test4 - We open multiple channels, block them and check to see if lease breaks will be retried after a timeout. This doesn't happen in this case. The server doesn't wait for the lease break to timeout and instead returns a successful create. Therefore no retries are done and the test fails. This is the same reason as for smb2.multichannel.oplocks.test3_specification.

Tested with both iptables and fsctl.

Note that multichannel was enabled by default just recently on Samba.
