New Revision: 247906
URL: http://svnweb.freebsd.org/changeset/base/247906
Log:
The hashmask returned by hashinit() is a valid index in the returned hash
array.
Fix a siftr(4) potential memory leak and INVARIANTS triggered kernel panic in
hashdestroy() by ensuring the last array index in the flow counter hash table
is
flushed of entries.
