Merge branch 'kcm-fix-two-syzcaller-issues'
Tom Herbert says: ==================== kcm: fix two syzcaller issues In this patch set: - Don't allow attaching non-TCP or listener sockets to a KCM mux. - In kcm_attach Check if sk_user_data is already set. This is under lock to avoid race conditions. More work is need to make all of the users of sk_user_data to use the same locking. - v2 Remove unncessary check for not PF_KCM in kcm_attach (suggested by Guillaume Nault) ==================== Signed-off-by: David S.
