2011-05-16Fix the SMB2 showstopper, found by an extended torture test from Volker.Jeremy Allison1-3/+25
In the oplock refactoring, the algorithm underwent an unnoticed change. In 3.5.x stat_opens were silently (i.e. no explicit code had comments explaining this) ignored when looking for oplock breaks and share mode violations. After the refactoring, the function find_oplock_types() no longer ignored stat_open entries in the share mode table when looking for batch and exclusive oplocks. This patch adds two changes to find_oplock_types() to ignore the case where the incoming open request is a stat open being tested against existing opens, and also when the incoming open request is a non-stat open being tested against existing stat opens. Neither of these cause an oplock break or share mode violation. Thanks a *lot* to Volker, who persevered in reproducing this problem.

2011-02-22s3-auth Rename auth_serversupplied_info varaiables: server_info -> session_infoAndrew Bartlett1-1/+1
These variables, of type struct auth_serversupplied_info were poorly named when added into 2001, and in good consistant practice, this has extended all over the codebase in the years since. The structure is also not ideal for it's current purpose. Originally intended to convey the results of the authentication modules, it really describes all the essential attributes of a session. This rename will reduce the volume of a future patch to replaced these with a struct auth_session_info, with auth_serversupplied_info confined to the lower levels of the auth subsystem, and then eliminated. (The new structure will be the output of create_local_token(), and the change in struct definition will ensure that this is always run, populating local groups and privileges).

2011-02-02Based on a conversation with Volker, refactor some of the oplock code to ↵Jeremy Allison1-71/+160
make it comprehensible. delay_for_oplocks() did 4 things. 1). Validation of existing oplock types. 2). Check for compatibility with batch oplocks (pass 1). 3). Check for compatibility with exclusive oplocks (pass 2). 4). Set the correct oplock type from the requested value. Refactor into 4 separate functions: 1). find_oplock_types() - does validation of oplock types and returns pointers to specific values. 2). delay_for_batch_oplocks() - the pass 1 phase above. 3). delay_for_exclusive_oplocks() - the pass 2 phase above 4). grant_fsp_oplock_type() - Set the correct oplock type from the requested value. Now separated out this code should be much easier to understand and modify. This also fixes an erroneous SMB_ASSERT which was hidden by the previous complexity of the single delay_for_oplocks() code.
