Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

V4L/DVB (13038): dvbdev: Remove an anoying/uneeded warning As pointed by Marcin Slusarz <marcin.slusarz@gmail.com>, the warns happens because CONFIG_DVB_MAX_ADAPTERS depends on CONFIG_DVB_CORE, and there are valid configs where DVB_CORE is not selected. This causes such warnings, for every V4L and common drivers that may or may not be compiled with DVB support: drivers/media/dvb/dvb-core/dvbdev.h:36:2: warning: #warning invalid CONFIG_DVB_MAX_ADAPTERS value We can safely remove the warning.

V4L/DVB (7538): Adds selectable adapter numbers as per module option The adapter_nr module options can be used to allocate static adapter numbers on a driver level. It avoids problems with changing DVB apapter numbers after warm/cold boot or device unplugging and repluging. Each driver holds DVB_MAX_ADAPTER long array of the preferred order of adapter numbers. options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a reversed allocation of adapter numbers. With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If both are already in use it will allocate the lowest free adapter number.

media: dvb-core: Enhance shared multi-frontend support Drivers for devices with multiple frontends which cannot be used concurrently due to hardware limitations which enforce that restriction by setting the mfe_shared field to 1 exhibit rather unfriendly behavior towards applications: The unavailable frontend devices cannot be opened at all, not even for read-only access to query information. Even worse, any open call is blocked for 5 seconds by default. Allow drivers for such devices to behave like regular busy frontend devices instead, i.e. still allowing concurrent read access to the unavailable frontend and denying concurrent write access with -EBUSY without delay. This patch does not alter the behavior of any existing driver to avoid regressions. Driver developers who wish to take advantage of this must ensure their driver can handle all read-only accesses to the unavailable frontend, and indicate the capability by setting the mfe_shared field to 2 instead of 1. Add a check to dvb-usb-init.c when automatically setting the mfe_shared field that when a driver has already set the field to 2, it is not overwritten. Document the additional capability in the code comment about mfe_shared.

V4L/DVB (3762): Add sysfs device links to dvb devices Currently in /sys/class/dvb/dvbX.demuxY/ we have: dev uevent With the patch, we have (for a PCI DVB device): dev device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:03:0d.0 uevent So userspace tools can (finally) work out which physical device a DVB adapter refers to. Previously you had to kinda look through dmesg and hope that it hadn't been dumped out of the buffer. This makes debugging a lot easier if the system has been up for a long time! This is done by adding an extra 'struct device *' parameter to dvb_register_adapter(). It will work with any kind of standard linux 'device'. Additionally, if someone has an embedded system which does things differently, they can simply supply 'NULL' and the behaviour will be as before - the link will simply not appear.

V4L/DVB (9227): MFE: Add multi-frontend mutual exclusion This add frontend R/W mutual exclusion. Prior to this point in time it was possible to open both frontends simultaneously which an MFE card cannot support. In order to stop this, a delayed open is performed which has the following function: - Return EBUSY after a configurable amount of time if a frontend is unavailable due to the other being in use. - Only allow opening of a frontend if the kernel thread of the other has stopped. This solution was chosen to allow switching between frontends to work as seamlessly as possible. When both frontends are actually opened simultaneously then one will only open, but if quick switching is performed between one of many then the new open will succeed in a clean fashion rather than interrupting a kernel thread.

media: dvb-core: Fix use-after-free due to race at dvb_register_device() dvb_register_device() dynamically allocates fops with kmemdup() to set the fops->owner. And these fops are registered in 'file->f_ops' using replace_fops() in the dvb_device_open() process, and kfree()d in dvb_free_device(). However, it is not common to use dynamically allocated fops instead of 'static const' fops as an argument of replace_fops(), and UAF may occur. These UAFs can occur on any dvb type using dvb_register_device(), such as dvb_dvr, dvb_demux, dvb_frontend, dvb_net, etc. So, instead of kfree() the fops dynamically allocated in dvb_register_device() in dvb_free_device() called during the .disconnect() process, kfree() it collectively in exit_dvbdev() called when the dvbdev.c module is removed.

media: fix kernel-doc markups Some identifiers have different names between their prototypes and the kernel-doc markup. Seome seems to be due to cut-and-paste related issues. Others need to be fixed, as kernel-doc markups should use this format: identifier - description Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> # IPU3 and V4L2 Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

media: dvbdev: fix building on ia64 Not sure why, but, on ia64, with Linaro's gcc 7.3 compiler, using #ifdef (CONFIG_I2C) is not OK. So, replace it by IS_ENABLED(CONFIG_I2C), in order to fix the builds there. Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

media: dvb-core: add helper functions for I2C binding The dvb_attach()/dvb_detach() methods are ugly hacks designed to keep using the I2C low-level API. The proper way is to do I2C bus bindings instead. Several modules were already converted to use it. Yet, it is painful to use it, as lots of code need to be duplicated. Make it easier by providing two new helper functions: - dvb_module_probe() - dvb_module_release() Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

[media] dvbdev: add a dvb_detach() macro The dvb_attach() was unbalanced, as there was no dvb_dettach. Ok, on current cases, the dettach is done by dvbdev, but that are some future corner cases where we may need to do this before registering the frontend. So, add a dvb_detach() and use it at dvb_frontend.c. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
