2013-10-08smbd: Simplify set_share_modeVolker Lendecke1-30/+15
With the find_share_mode simplification we don't need fill_share_mode anymore. So this coalesces add_share_mode as well. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
2013-10-08smbd: Simplify find_share_mode_entry callersVolker Lendecke1-46/+25

2013-10-06smbd: Restructure brl_get_locks_readonlyVolker Lendecke1-10/+103
This is step 1 to get rid of brl_get_locks_internal with its complex readonly business. It also optimizes 2 things: First, it uses dbwrap_parse_record to avoid a talloc and memcpy, and second it uses talloc_pooled_object. And -- hopefully it is easier to understand the caching logic with fsp->brlock_rec and the clustering escape.

2013-10-06smbd: Avoid an if-statement per read/write in the non-clustered caseVolker Lendecke1-4/+4
Without clustering, fsp->brlock_rec will never be set anyway. In the clustering case we can't use the seqnum trick, so this is slow enough that the additional if-statement does not matter in this case anyway. In the non-clustered case it might. Have not measured it, but every little bit helps I guess. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>

The comment for this routine said: > Modifies d->num_share_modes, watch out in routines iterating over > that array. Well, it turns out that *every* caller of this API got it wrong. So I think it's better to change the routine. This leaves the array untouched while iterating but filters out the deleted ones while saving them back to disk.

2012-06-28s3:brlock: s/int/uint64_t for fnumStefan Metzmacher1-1/+1
fsp->fnum and lock->fnum are uint64_t already and we should not truncate the value here. Currently this doesn't matter as we only use 16-bit. But as 'int' is int32_t and we later compare fnum with lock->fnum == fnum, the cast from int32_t to uint64_t goes via int64_t instead of uint32_t. This means even if fsp->fnum just uses 32-bit of the uint64_t we'll get the wrong result, as the implicit cast from a negative int32_t value to uint64_t adds 0xFFFFFFFF00000000. metze
