2012-12-18Fix bug #9196 - defer_open is triggered multiple times on the same request.Jeremy Allison1-3/+3
get_deferred_open_message_state_smb2() is buggy in that it is checking the wrong things to determine if an open is in the deferred state. It checks if (smb2req->async_te == NULL) which is incorrect, as we're not always async in a deferred open - remove this. It should check instead state->open_was_deferred as this is explicity set to 'true' when an open is going deferred, so add this check.

A worker smbd is as not long-lived as the main smbd, but as the async echo handler exits when the worker smbd does, passing "true" here is the right thing to do and fixes our clear_if_first handling when the async echo handler is active.

POSIX ACLs backend. Change can_delete_directory() to can_delete_directory_fsp(), as we only ever call this from an open directory file handle. This allows us to use OpenDir_fsp() instead of OpenDir(). OpenDir() re-checks the ACL on the directory, which may refuse DIR_LIST permissions. OpenDir_fsp() does not. As this is a file-server internal check to see if the directory actually contains any files before setting delete on close, we can ignore the ACL here (Windows does).

I only found this as I'm making raw.acls and smb2.acls pass against 3.6.x and 4.0.0 with acl_xattr mapped onto a POSIX backend. An incoming inheritable ACE entry containing only one permission, WRITE_DATA maps into a POSIX owner perm of "-w-", which violates the principle that the owner of a file/directory can always read.

2012-11-13smbd: Remove NT4 compatability handling in posix -> NT ACL conversionAndrew Bartlett2-108/+1
NT4 is long dead, and we should not change which ACL we return based on what we think the client is. The reason we should not do this, is that if we are using vfs_acl_xattr then the hash will break if we do. Additionally, it would require that the python VFS interface set the global remote_arch to fake up being a modern client. This instead seems cleaner and removes untested code (the tests are updated to then handle the results of the modern codepath). The supporting 'acl compatability' parameter is also removed.

2012-10-29Fix bug #9329 - Directory listing with SeBackup can crash smbd.Jeremy Allison3-1/+37
When we do a become_root()/unbecome_root() pair to temporarily raise privilege, this NULLs out the NT token. If we're within a become_root()/unbecome_root() pair then return the previous token on the stack as our NT token. This is what we should be using to check against NT ACLs in the file server. This copes with security context changing when removing a file on close under the context of another user (when 2 users have a file open, one sets delete on close and then the other user has to actually do the delete).
