Return-Path: From: Andrei Emeltchenko To: linux-bluetooth@vger.kernel.org Subject: [PATCHv3 0/3] Bluetooth: Change socket lock to l2cap_chan lock Date: Wed, 22 Feb 2012 17:11:54 +0200 Message-Id: <1329923517-5425-1-git-send-email-Andrei.Emeltchenko.news@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Andrei Emeltchenko Changing socket lock to L2CAP chan lock in L2CAP code. Needed for implementing protocols above L2CAP without creating sockets. Changes: * PATCHv3: Do not remove couple of empty lines and remove old comments. * PATCHv2: Rebase remaining parts against latest tree and merge all patches dealing with converting sk lock to chan lock together following recommendation from Ulisses and Gustavo. * PATCHv1: Added extra line (per Gustavo comment) * RFCv6: Same code but patches 2,3 and 4 from RFCv5 are merged together following recommendations from review. * RFCv5: Fixed locking bug in l2cap_data_channel, added locks in l2cap_sock_shutdown function, fixed several styles issues. * RFCv4: Better split patches so they looks more clear and obvious, taking coments about naming change and delete unused vars. See diff change from the previous version below: * RFCv3: Split the big patch to several small (I believe logical) chunks, remove unneded locks from cleanup_listen, use the same arguments for locked/unlocked socket error functions. * RFCv2: Convert l2cap channel list back to mutex from RCU list. Andrei Emeltchenko (3): Bluetooth: Add unlocked __l2cap_chan_add function Bluetooth: Change sk lock to chan lock in L2CAP core Bluetooth: Remove socket lock check net/bluetooth/l2cap_core.c | 175 ++++++++++++++++++++++++++------------------ net/bluetooth/l2cap_sock.c | 26 +++++-- 2 files changed, 125 insertions(+), 76 deletions(-) -- 1.7.9
