break behavior
|
|
Share modes are tested elsewhere, and there is currently an outstanding
issue about share mode contention for nt-passthrough levels:

Try a rename with a wide-open share mode on an already open file
and the there is still share mode contention. For the reason why
see:

Msft's anser:
After further review, The reason for server to fail with sharing
violation is that the windows server that executes a path-based
rename request opens the file for DELETE access, but only with
FILE_SHARED_READ as ShareAccess . Therefore, the existing
open(frame 76), which has shared read/write/delete , is compatible
with the Windows servers access mode (DELETE), but Windows servers
open is not compatible with access mode in existing open.
Note that it is correct to state that the logic in Windows server
could have been written to allow shared read/write/delete in which
case it would succeed as you mention. The behavior here is
historical based on the existing implementation.

Some servers choose to mark a client as bad if they fail an oplock
break request by timing out (win7 is an example). Once the client is
marked as bad, future oplock requests will timeout instantly. This
causes subsequent runs of this test to fail, so rather than erroring
out as a failure, a warning is printed instead.
There is also a bug in w2k3 where it was incorrectly returning
contending a share mode lock. It worked in XP and has been re-fixed
in win7.
This can also now be run against samba3.

breaks
|
|
In light of the INVALID_LEVEL that is seen for RAW_SFILEINFO_END_OF_FILE_INFO
requests on a path, I'm changing these back to using the passthrough
RAW_SFILEINFO_END_OF_FILE_INFORMATION to test the oplock break behavior as
originally intended
|
|
SET_END_OF_FILE_INFO
The passtrhough version of SET_END_OF_FILE_INFO is tested in
RAW-SFILEINFO-END-OF-FILE.
Additionally, the first opener is changed to use SHARE_WRITE for the
share mode since SET_END_OF_FILE_INFO actually writes data to the file
via truncating/extending.

This reduces compile time somewhat.

In order to implement root_fid in the s4 SMB server we need to declare
it as a handle type, just as for other fnum values in SMB. This
required some extensive (but simple) changes in many bits of code.

We were pulling junk memory for our stream names after the reordering
of the struct definition.
|
|
Previously, the oplock torture tests, being single threaded, required
the server to return oplock break requests, and other SMB packets
in a specific order for us to verify "correctness".
Of course, in several cases the protocol allows the break packets,
especially breaks to levelII to come back in any order. With tevent
we're now able to wait for oplock breaks in the middle of a torture
test.
I've added a helper to do this, and modified all oplock tests to allow
returning of oplock breaks in any order.

Allows "make test" and other harnesses to print cleaner output.

* test if oplocks are granted when requesting delete-on-close
* test how oplocks are broken by byte-range-lock requests

BATCH22 left to fix.

Eventually, we should move some of these parameters into a separate
struct (perhaps into smb_transport_options?), to avoid the long lists of
parameters.

Probably that's already somewhere else, but I did not find it.

This is really strange as, it seems to complete ignore
oplocks and share modes and doesn't match the behavior
of RENAME and NTRENAME.
