Subject: [PATCH] libsepol/cil: Do not add NULL node when inserting key into
|
|
symtab
|
|
|
|
Allow inserting a key without providing a node.
|
|
|
|
This will make it easier to properly resolve call arguments where
|
|
a key might need to be temporarily removed to search for a datum
|
|
that is not declared within the call. Since the node is already
|
|
in the node list, re-inserting the key without this option would
|
|
add another link to the node and cause problems.
|
|
|
|
Also, do not add the node to the datum's node list if the result
|
|
of the call to hashtab_insert() is SEPOL_EEXIST because the datum
|
|
is a duplicate and will be destroyed.
