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) Tom Herbert (2): kcm: Only allow TCP sockets to be attached to a KCM mux kcm: Check if sk_user_data already set in kcm_attach net/kcm/kcmsock.c | 25 +++++++++++++++++++++---- 1 file changed, 21 insertions(+), 4 deletions(-) -- 2.11.0
