2013-09-12smbd: Properly protect against invalid lock dataVolker Lendecke1-0/+6
If someone messes with brlock.tdb and inserts an invalid record length, this will lead to memcpy overwriting a few bytes behind malloc'ed data.

2013-09-03smbd: Fix flawed share_mode_stale_pid APIVolker Lendecke2-9/+50
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.

servers in traverses We should not remove locks of disconnected opens just like that.

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
