-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.

-Fixes: 2b018d57ff18 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release")
