Subject: [PATCH] iwlwifi: fix key removal
|
||||||
|
|
||||||
|
commit 5dcbf480473f6c3f06ad2426b7517038a2a18911 upstream.
|
||||||
|
|
||||||
|
When trying to remove a key, we always send key
|
||||||
|
flags just setting the key type, not including
|
||||||
|
the multicast flag and the key ID. As a result,
|
||||||
|
whenever any key was removed, the unicast key 0
|
||||||
|
would be removed, causing a complete connection
|
||||||
|
loss after the second rekey (the first doesn't
|
||||||
|
cause a key removal). Fix the key removal code
|
||||||
|
to include the key ID and multicast flag, thus
|
||||||
|
removing the correct key.
