media: dvb-core: Fix use-after-free due on race condition at dvb_netA race condition may occur between the .disconnect function, whichis called when the device is disconnected, and the dvb_device_open()function, which is called when the device node is open()ed.This results in several types of UAFs.The root cause of this is that you use the dvb_device_open() function,which does not implement a conditional statementthat checks 'dvbnet->exit'.So, add 'remove_mutex` to protect 'dvbnet->exit' and uselocked_dvb_net_open() function to check 'dvbnet->exit'.[mchehab: fix a checkpatch warning]Link: https://lore.kernel.org/linux-media/20221117045925.14297-3-imv4bel@gmail.comSigned-off-by: Hyunwoo Kim Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/include/media/dvb_net.h

de163422 - media: drop unnecessary networking includes

Fri, 03 Feb 2023 23:31:29 +0000

media: drop unnecessary networking includesdvb_net.h includes a bunch of core networking headers which increasesthe number of objects rebuilt when we touch them. They are unnecessaryfor the header itself and only one driver has an indirect dependency.tveeprom.h includes if_packet to gain access to ETH_ALEN. Thisis a bit of an overkill because if_packet.h pulls in skbuff.h.The definition of ETH_ALEN is in the uAPI header, which isvery rarely touched, so switch to including that.This results in roughly 250 fewer objects built when skbuff.his touched (6028 -> 5788).Signed-off-by: Jakub Kicinski Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/include/media/dvb_net.h
