[PATCH 0/4] Bluetooth: L2CAP: part 2 of l2cap_conn::chan_l locking fixes

Posted by Pauli Virtanen 3 weeks, 3 days ago

Rebase to fix conflict in remaining commits from series
https://lore.kernel.org/linux-bluetooth/cover.1788013041.git.pav@iki.fi/

Fixed minor conflict vs. moved mutex_lock + l2cap_chan_lock in diff
context
commit ddaccd985bb0 ("Bluetooth: L2CAP: fix out-of-bounds write in l2cap_ecred_connect")

No other changes than resolving that.

Pauli Virtanen (4):
  Bluetooth: L2CAP: take lock for l2cap_chan_del in
    l2cap_ecred_rsp_defer
  Bluetooth: L2CAP: annotate locking for l2cap_chan_del()
  Bluetooth: L2CAP: annotate locking for l2cap_ops callbacks
  Bluetooth: L2CAP: refuse __l2cap_chan_add if chan already has conn
