Szymon Janc 83ebb9ec73 Bluetooth: Fix not registering BR/EDR SMP channel with force_bredr flag ... If force_bredr is set SMP BR/EDR channel should also be for non-SC capable controllers. Since hcidev flag is persistent wrt power toggle it can be already set when calling smp_register(). This resulted in SMP BR/EDR channel not being registered even if HCI_FORCE_BREDR_SMP flag was set. This also fix NULL pointer dereference when trying to disable force_bredr after power cycle. BUG: unable to handle kernel NULL pointer dereference at 0000000000000388 IP: [<ffffffffc0493ad8>] smp_del_chan+0x18/0x80 [bluetooth] Call Trace: [<ffffffffc04950ca>] force_bredr_smp_write+0xba/0x100 [bluetooth] [<ffffffff8133be14>] full_proxy_write+0x54/0x90 [<ffffffff81245967>] __vfs_write+0x37/0x160 [<ffffffff813617f7>] ? selinux_file_permission+0xd7/0x110 [<ffffffff81356fbd>] ? security_file_permission+0x3d/0xc0 [<ffffffff810eb5b2>] ? percpu_down_read+0x12/0x50 [<ffffffff812462a5>] vfs_write+0xb5/0x1a0 [<ffffffff812476f5>] SyS_write+0x55/0xc0 [<ffffffff817eb872>] entry_SYSCALL_64_fastpath+0x1a/0xa4 Code: 48 8b 45 f0 eb c1 0f 1f 00 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 f6 05 c6 3b 02 00 04 55 48 89 e5 41 54 53 49 89 fc 75 4b <49> 8b 9c 24 88 03 00 00 48 85 db 74 31 49 c7 84 24 88 03 00 00 RIP [<ffffffffc0493ad8>] smp_del_chan+0x18/0x80 [bluetooth] RSP <ffff8802aee3bd90> CR2: 0000000000000388 Signed-off-by: Szymon Janc <szymon.janc@codecoup.pl> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>		2016-09-19 20:19:34 +02:00
