Subject: [PATCH] checkpolicy: destroy the class datum if it fails to
|
|
initialize
|
|
|
|
require_class() allocate memory for its variable "class_datum_t *datum"
|
|
and calls symtab_init(&datum->permissions, PERM_SYMTAB_SIZE). If this
|
|
second call fails, datum is not freed.
|
|
|
|
Fix this memory leak.
