## Description

In the Linux kernel, the following vulnerability has been resolved:  can: isotp: fix timer drain order, wakeup handling and tx_gen ordering  This patch is a follow-up to commit cf070fe33bfb ("can: isotp: serialize TX state transitions under so->rx_lock") which addresses following sashiko-bot findings:  - isotp_sendmsg(): drain so->txfrtimer first so a stale callback can't   re-arm echotimer after the claim  - isotp_release(): wake so->wait after forcing ISOTP_SHUTDOWN so a   sleeping sendmsg() claim isn't stranded  - isotp_sendmsg(): have both wait_event_interruptible() calls in   isotp_sendmsg() also wake on ISOTP_SHUTDOWN and do not return claim to   IDLE to avoid corrupting a concurrent isotp_release() process.  - isotp_sendmsg(): handle potential claim of a new transfer when   the wait_event_interruptible() call returns in CAN_ISOTP_WAIT_TX_DONE   mode. Don't touch timers and states of the new transfer if a new thread   incremented so->tx_gen before getting the lock at err_event_drop.  - isotp_sendmsg(): handle a stuck can_send() and omit timer and state   changes if a new transfer was claimed. wait_tx_done() returns the error   recorded in so->tx_result[], tagged with the caller's own generation.  - isotp_tx_timeout(): on a claimed timeout, record the ECOMM error for   the timed-out transfer's own generation in so->tx_result[]; sk->sk_err   is raised unconditionally, same as every other error path here.  - isotp_tx_gen_done()/isotp_tx_timeout(): always read tx.state (acquire)   before tx_gen - the reverse order let a weakly ordered CPU pair a fresh   tx.state with a stale tx_gen/tx_result slot.  - isotp_sendmsg(): wait_tx_done: drain sk_err via sock_error() once we   have read the result from so->tx_result[], so an already-reported error   doesn't stay latched for a later poll()/SO_ERROR.  Also align the remaining lock-free so->tx.state/rx.state/cfecho accesses and use skb->hash as unique loopback echo frame indicator.
