Subject: [PATCH v2 net-next 0/2] kcm: fix two syzcaller issues
Date: Wed, 24 Jan 2018 12:35:39 -0800 [thread overview]
Message-ID: <20180124203541.3172-1-tom@quantonium.net> (raw)
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
