+Subject: [PATCH] pppoe: Lacks DST MAC address check
+
+A pppoe session is identified by its session ID and MAC address.
+Currently pppoe does not check if the received pkg has the correct
+MAC address. This is a problem when the eth I/F is in promisc mode
+as then any DST MAC address is accepted.

+Subject: [PATCH] ppp: don't override sk->sk_state in pppoe_flush_dev()
+
+Since commit 2b018d57ff18 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release"),
+pppoe_release() calls dev_put(po->pppoe_dev) if sk is in the
+PPPOX_ZOMBIE state. But pppoe_flush_dev() can set sk->sk_state to
+PPPOX_ZOMBIE _and_ reset po->pppoe_dev to NULL. This leads to the
+following oops:

+Subject: [PATCH] ppp: fix pppoe_dev deletion condition in pppoe_release()
+
+We can't rely on PPPOX_ZOMBIE to decide whether to clear po->pppoe_dev.
+PPPOX_ZOMBIE can be set by pppoe_disc_rcv() even when po->pppoe_dev is
+NULL. So we have no guarantee that (sk->sk_state & PPPOX_ZOMBIE) implies
+(po->pppoe_dev != NULL).
+Since we're releasing a PPPoE socket, we want to release the pppoe_dev
+if it exists and reset sk_state to PPPOX_DEAD, no matter the previous
+value of sk_state. So we can just check for po->pppoe_dev and avoid any
+assumption on sk->sk_state.
