2012-07-19s3-aio: Panic if we try to close a fsp with outstanding aio requestsVolker Lendecke1-1/+15
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.

2012-07-18loadparm: make the source3/ lp_ functions take an explicit TALLOC_CTX *.Rusty Russell1-5/+5
They use talloc_tos() internally: hoist that up to the callers, some of whom don't want to us talloc_tos(). A simple patch, but hits a lot of files. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

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.
