In general functions that don't return any memory should not take a memory context.
Otherwise it is too easy to have a bug like this where memory is leaked
Two new samba4 bugs have been filed for the two corresponding known
failures. For the short term raw.sfileinfo had to be removed from
quicktest. It is no longer an individual test, but a test-suite and
quicktest can only run top level tests.
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

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.
See what happens when we have multiple outstanding lock requests and
we try to cancel both of them within a single LockingAndX.
On Windows, it seems only the first lock in the array is cancelled,
and the second is left pending. Though, this behavior goes against
the MS-CIFS spec.
* test that 2 locks in a single LockAndX are transactional
* test that 1 unlock and 1 lock in a single LockAndX are not
transactional
* test that SMB2 doesn't like mixed lock/unlock in a single
PDU
Abstract the server requirements to pass some BRL tests.
* The new default for >64bit lock tests, is that the server should
return STATUS_INVALID_LOCK_RANGE.
* Add parameter for targets that don't implement DENY_DOS
When windows abandons a DRS sync, it will sometimes re-use the same bind handle for
a new sync. This means we need to check the DN of the sync and blank the getnc_state
if the DN has changed.
This also fixes the UDV to use the highest uSN for the partition, not for
the whole SAM.
right. The previous bugs were due to the fact that get_nt_acl_internal()
could return an NTSTATUS error if there was no stored ACL blob, but
otherwise would return the underlying ACL from the filysystem. Fix
this so it always returns a valid acl if it can, and if it does not
its an error to be reported back to the client. This then changes
the inherit acl code. Previously we were trying to match Windows
by setting a minimal ACL on a new file that didn't inherit anything
from a parent directory. This is silly - the returned ACL wouldn't
match the underlying UNIX permissions. The current code will correctly
inherit from a parent if a parent has any inheritable ACE entries
that apply to the new object, but will return a mapping from the
underlying UNIX permissions if the parent has no inheritable entries.
This makes much more sense for new files/directories.

posix_fallocate is more efficient than manual zero'ing the file. When
preallocation in kernel space is supported it's extremely fast. Support for
preallocation at fs layer via posix_fallocate and fallocate at kernel site
can be found in Linux kernel 2.6.23/glibc 2.10 with ext4, XFS and OCFS2. Other
systems that I know of which support fast preallocation in kernel space are
AIX 6.1 with JFS2 and recent Solaris versions with ZFS maybe UFS2, too.
People who have a system with preallocation in kernel space might want to set
"strict allocate = yes". This reduces file fragentation and it's also safer for
setups with quota being turned on.
As of today most systems still don't have preallocation in kernel space, and
that's why "strict allocate = no" will stay the default for now.
reads off the underlying filesystem. Ensure that vfs_acl_tdb.c
returns NT_STATUS_NOT_FOUND, not NT_STATUS_OBJECT_NAME_NOT_FOUND
when it can't find a blob matching the file.
