2019-07-07gtp: fix use-after-free in gtp_encap_destroy()Taehee Yoo
gtp_encap_destroy() is called twice. 1. When interface is deleted. 2. When udp socket is destroyed. either gtp->sk0 or gtp->sk1u could be freed by sock_put() in gtp_encap_destroy(). so, when gtp_encap_destroy() is called again, it would uses freed sk pointer. patch makes gtp_encap_destroy() to set either gtp->sk0 or gtp->sk1u to null. in addition, both gtp->sk0 and gtp->sk1u pointer are protected by rtnl_lock. so, rtnl_lock() is added.

When smmu is enable, if execute the perftest command and then use 'kill -9' to exit, follow this operation repeatedly, the kernel will have a high probability to print the following smmu event: arm-smmu-v3 arm-smmu-v3.1.auto: event 0x10 received: arm-smmu-v3 arm-smmu-v3.1.auto: 0x00007d0000000010 arm-smmu-v3 arm-smmu-v3.1.auto: 0x0000020900000080 arm-smmu-v3 arm-smmu-v3.1.auto: 0x00000000f47cf000 arm-smmu-v3 arm-smmu-v3.1.auto: 0x00000000f47cf000 This is because the hw will periodically refresh the qpc cache until the next reset.

For the Marvell HCI UART we have to upload two firmware files. The first one is only for switching the baudrate of the device to a higher baudrate. After the baudrate switching firmware has been uploaded the device waits for a final ack (0x5a) before actually switching the baudrate. To send this final ack with the old baudrate give the hci ldisc workqueue a chance to run before switching the baudrate. Without this the final ack will never be received by the device and firmware upload fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
