2012-09-08s3: Fix a panic when shutting downVolker Lendecke1-10/+32
When a client disconnects while we have aio open, there is no close request that cleans up. We can't send out the replies anymore, so just drop the aio requests that are pending.

The core smbd must have taken care of this. If we don't do this properly, we have a race of the close(2) against a pwrite(2). We might end up writing to the wrong file.

2012-06-03s3: Fix an assert to trigger in close_remove_share_modeStefan Metzmacher1-6/+17
In case we have a left-over entry in the share mode entry array, the SMB_ASSERT(got_tokens) is likely to kick in. It happens when we are about to delete a file with initial delete on close. We don't have a delete on close token set in the locking.tdb record. We see the fsp->initial_delete_on_close set, add the delete_on_close token to lck. Then "delete_file" is being set to true. Then later on we do the notify_deferred_opens. This walks the list, also checking for share_mode_stale_pid. We have already deleted our own share mode entry, share_mode_stale_pid() sees the left-over entry. It not also deletes that one but also the delete on close token. This leads to a different view of "delete_file" a.k.a. "got_tokens" further down in close_remove_share_mode, leading the SMB_ASSERT to fire. This patch attempts to fix the issue by keeping around our own share mode entry for almost the whole routine, preventing share_mode_stale_pid() from removing the delete tokens.

2012-05-19Move the set_write_time() call to after get_existing_share_mode_lock() ↵Jeremy Allison1-3/+15
returns with a share mode. get_existing_share_mode_lock() isn't really the right call here, as we're being called after close_remove_share_mode() inside close_normal_file() so it's quite normal to not have an existing share mode here. However, get_share_mode_lock() doesn't work because that will create a new share mode if one doesn't exist - so stick with this call (just ignore any error we get if the share mode doesn't exist. The previous commit raised the error message debug level inside get_share_mode_lock_internal() so we don't always get a level 1 error message if get_existing_share_mode_lock() fails.
