Raw Normal View History

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!

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

[media] dvb-core: allow demods to specify the supported delsys The dvb were originally written for DVB-T/C/S and ATSC. So, the original frontend struct has fields to describe only those three standards. While 2nd gen standards are similar to these, new standards like DSS, ISDB and CTTB don't fit on any of the above types. While there's a way for the drivers to explicitly change whatever default DELSYS were filled inside the core, still a fake value is needed there, and a "compat" code to allow DVBv3 applications to work with those delivery systems is needed. This is good for a short term solution, while applications aren't using DVBv5 directly. However, at long term, this is bad, as the compat code runs even if the application is using DVBv5. Also, the compat code is not perfect, and only works when the frontend is capable of auto-detecting the parameters that aren't visible by the faked delivery systems. So, let the frontend fill the supported delivery systems at the device properties directly. The future plan is that the drivers will stop filling ops->info.type, filling, instead, ops->delsys. This will allow multi-frontend devices like drx-k to use just one frontend structure for all supported delivery systems. Of course, the core will keep using it, in order to keep allowing DVBv3 calls.

media: dvb: convert tuner_info frequencies to Hz Right now, satellite tuner drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal tuners capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid tuners. So, convert everything to specify tuner frequencies in Hz. Plese notice that a similar patch is also needed for frontends.

Not all drivers implement it, as returning the driver from low power may require to re-load the firmware, with takes some time. Also, some drivers may delay it.

[media] dvb-core, tda18271c2dd: define get_if_frequency() callback Tuners in general convert a high frequency carrier into an Intermediate Frequency (IF). Digital tuners like tda18271, xc3028, etc. generally allow changing the IF frequency, although they generally have recommented settings for the IF. Analog tuners, have a fixed IF frequency, that depends on the physical characteristics of some analog components. For digital tuners, it makes sense to have ways to configure IF, via the tuner's configuration structure, like what's done inside the tda18271-fe maps. The demods need to know what IF is used by the tuner, as it will need to convert internally from IF into baseband. Currently, the bridge driver needs to fill a per-demod configuration struct for it, or pass it via a dvb_attach parameter. The tda18271 datasheet recommends to use different IF's for different delivery system types and for different bandwidths. The DRX-K demod also needs to know the IF frequency in order to work, just like all other demods. However, as it accepts different delivery systems (DVB-C and DVB-T), the IF may change if the standard and/or bandwidth is changed. So, the usual procedure of passing it via a config struct doesn't work. One might try to code it as two separate IF frequencies, or even as a table in function of the delivery system and the bandwidth, but this will be messy. So, it is better and simpler to just add a new callback for it and require the tuners that can be used with MFE frontends like drx-k to implement a new callback to return the used IF.

[media] tuner-core/simple: get_rf_strength can be tuner mode specific The get_rf_strength op in tuner-simple is valid only for the radio mode. But due to the way get_signal in analog_demod_ops was designed it would overwrite the signal value with a bogus value when in TV mode. Pass a pointer to the signal value instead, and when not in radio mode leave it alone in the tuner-simple. This broke in commit 030755bde42bbed133182b0ece7c7a9c759478e8 (tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before that this was working correctly.

media: dvb: represent min/max/step/tolerance freqs in Hz Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

media: dvb: represent min/max/step/tolerance freqs in Hz Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

[media] dvb-core: allow demods to specify the supported delsys The dvb were originally written for DVB-T/C/S and ATSC. So, the original frontend struct has fields to describe only those three standards. While 2nd gen standards are similar to these, new standards like DSS, ISDB and CTTB don't fit on any of the above types. While there's a way for the drivers to explicitly change whatever default DELSYS were filled inside the core, still a fake value is needed there, and a "compat" code to allow DVBv3 applications to work with those delivery systems is needed. This is good for a short term solution, while applications aren't using DVBv5 directly. However, at long term, this is bad, as the compat code runs even if the application is using DVBv5. Also, the compat code is not perfect, and only works when the frontend is capable of auto-detecting the parameters that aren't visible by the faked delivery systems. So, let the frontend fill the supported delivery systems at the device properties directly. The future plan is that the drivers will stop filling ops->info.type, filling, instead, ops->delsys. This will allow multi-frontend devices like drx-k to use just one frontend structure for all supported delivery systems. Of course, the core will keep using it, in order to keep allowing DVBv3 calls.

[media] Rename set_frontend fops to set_frontend_legacy Passing DVBv3 parameters to set_frontend is not fun, as the core doesn't have any way to know if the driver is using the v3 or v5 parameters. So, rename the callback and add a new one to allow distinguish between a mixed v3/v5 paramenter call from a pure v5 call. After having all frontends to use the new way, the legacy call can be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

[media] dvb_frontend: pass the props cache to get_frontend() as arg Instead of using the DTV properties cache directly, pass the get frontend data as an argument. For now, everything should remain the same, but the next patch will prevent get_frontend to affect the global cache. This is needed because several drivers don't care enough to only change the properties if locked. Due to that, calling G_PROPERTY before locking on those drivers will make them to never lock. Ok, those drivers are crap and should never be merged like that, but the core should not rely that the drivers would be doing the right thing.

This 18 bit field, when present, carries the index of the DVB-S2 physical layer scrambling sequence as defined in clause 5.5.4 of EN 302 307. There is no explicit signalling method to convey scrambling sequence index to the receiver. If S2 satellite delivery system descriptor is available it can be used to read the scrambling sequence index (EN 300 468 table 41). By default, gold scrambling sequence index 0 is used. The valid scrambling sequence index range is from 0 to 262142. Increase the DVB API version in order userspace to be aware of the changes.

Rather than passing fixed structures across the user/kernel boundary, which need to be revised for each new modulation type (or feature the kernel developers want to add), this implements a simpler message based approach, allowing fe commands to be broken down into a series of small fixed size transactions, presented in an array. The goal is to avoid changing the user/kernel ABI in the future, by simply creating new frontend commands (and sequencies of commands) that help us add support for brand new demodulator, delivery system or statistics related commmands. known issues: checkpatch voilations feedback from various developers yet to be implemented, relating to namespace conventions, variable length array passing conventions, and generally some optimization. This patch should support all existing tuning mechanisms through the new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

This 18 bit field, when present, carries the index of the DVB-S2 physical layer scrambling sequence as defined in clause 5.5.4 of EN 302 307. There is no explicit signalling method to convey scrambling sequence index to the receiver. If S2 satellite delivery system descriptor is available it can be used to read the scrambling sequence index (EN 300 468 table 41). By default, gold scrambling sequence index 0 is used. The valid scrambling sequence index range is from 0 to 262142. Increase the DVB API version in order userspace to be aware of the changes.

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] dvb_frontend: move kref to struct dvb_frontend This commit amends my old commit fe35637b0a9f ("[media] dvb_frontend: eliminate blocking wait in dvb_unregister_frontend()"), which added kref to struct dvb_frontend_private. It turned out that there are several use-after-free bugs left, which affect the struct dvb_frontend. Protecting it with kref also protects struct dvb_frontend_private, so we can simply move it. This is how the use-after-free looks like in KASAN: BUG: KASAN: use-after-free in string+0x60/0xb1 at addr ffff880033bd9fc0 Read of size 1 by task kworker/0:2/617 CPU: 0 PID: 617 Comm: kworker/0:2 Not tainted 4.8.0-rc1-hosting+ #60 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Workqueue: usb_hub_wq hub_event 0000000000000000 ffff880033757218 ffffffff81394e50 ffff880033bd9fd0 ffff880035c03b00 ffff880033757240 ffffffff811f271d ffff880033bd9fc0 1ffff1000677b3f8 ffffed000677b3f8 ffff8800337572b8 ffffffff811f2afe Call Trace: [...] [<ffffffff813a2d2f>] vsnprintf+0x39d/0x7e9 [<ffffffff813993f9>] add_uevent_var+0x10f/0x1dc [<ffffffff814fe5ca>] rc_dev_uevent+0x55/0x6f [<ffffffff814438f8>] dev_uevent+0x2e1/0x316 [<ffffffff81399744>] kobject_uevent_env+0x27e/0x701 [<ffffffff81399bd2>] kobject_uevent+0xb/0xd [<ffffffff81443445>] device_del+0x322/0x383 [<ffffffff81500c0c>] rc_unregister_device+0x98/0xc3 [<ffffffff81508fb4>] dvb_usb_remote_exit+0x7a/0x90 [<ffffffff81506157>] dvb_usb_exit+0x1d/0xe5 [<ffffffff81506e90>] dvb_usb_device_exit+0x69/0x7d [<ffffffff8150a181>] pctv452e_usb_disconnect+0x7b/0x80 [...] Object at ffff880033bd9fc0, in cache kmalloc-16 size: 16 Allocated: [...] Freed: PID = 617 [...] [<ffffffff811f034c>] kfree+0xd9/0x166 [<ffffffff814fe513>] ir_free_table+0x2f/0x51 [<ffffffff81500bc1>] rc_unregister_device+0x4d/0xc3 [<ffffffff81508fb4>] dvb_usb_remote_exit+0x7a/0x90 [<ffffffff81506157>] dvb_usb_exit+0x1d/0xe5 [<ffffffff81506e90>] dvb_usb_device_exit+0x69/0x7d [<ffffffff8150a181>] pctv452e_usb_disconnect+0x7b/0x80 Another one: BUG: KASAN: use-after-free in do_sys_poll+0x336/0x6b8 at addr ffff88003563fcc0 Read of size 8 by task tuner on fronte/1042 CPU: 1 PID: 1042 Comm: tuner on fronte Tainted: G B 4.8.0-rc1-hosting+ #60 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 0000000000000000 ffff88003353f910 ffffffff81394e50 ffff88003563fd80 ffff880035c03200 ffff88003353f938 ffffffff811f271d ffff88003563fc80 1ffff10006ac7f98 ffffed0006ac7f98 ffff88003353f9b0 ffffffff811f2afe Call Trace: [...] [<ffffffff812289b3>] do_sys_poll+0x336/0x6b8 [...] [<ffffffff81228ed9>] SyS_poll+0xa9/0x194 [...] Object at ffff88003563fc80, in cache kmalloc-256 size: 256 Allocated: [...] Freed: PID = 617 [...] [<ffffffff811f034c>] kfree+0xd9/0x166 [<ffffffff814eb60d>] dvb_unregister_device+0xd6/0xe5 [<ffffffff814fa4ed>] dvb_unregister_frontend+0x4b/0x66 [<ffffffff8150810b>] dvb_usb_adapter_frontend_exit+0x69/0xac [<ffffffff8150617d>] dvb_usb_exit+0x43/0xe5 [<ffffffff81506e90>] dvb_usb_device_exit+0x69/0x7d [<ffffffff8150a181>] pctv452e_usb_disconnect+0x7b/0x80 Signed-off-by: Max Kellermann <max.kellermann@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.

V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support. A detailed description from the original patches 2 years ago: "The WinTV-HVR3000 has a single transport bus which is shared between a DVB-T and DVB-S modulator. These patches build on the bus acquisition cx88 work from a few weeks ago to add support for this. So to applications the HVR3000 looks like this: /dev/dvb/adapter0/fe0 (cx24123 DVB-S demod) /dev/dvb/adapter0/fe1 (cx22702 DVB-T demod) Additional boards continue as before, eg: /dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod) The basic change is removing the single instance of the videobuf_dvb in cx8802_dev and saa7134_dev(?) and replacing it with a list and some supporting functions. *NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so two or three current cx88 patches appear to be reversed by this tree, this will be cleaned up in the near future. The patches missing change the mutex handing to core->lock, fix an enumeration problem." It should be recognised that a number of people have been maintaining this patchset. Significant levels of Kudos to everyone one involved, including but not limited to: Darron Broad Fabio M. Di Nitto Carlo Scarfoglio Hans Werner Without the work of these people, and countless others, my two year old patches would of died on the Mercurial linuxtv.org vine a long time ago. TODO: Revise these patches a little further so that the need for demux1 and dvr0 is optional, not mandatory on the HVR3000. HISTORY (darron): This is the last update to MFE prepared by Hans which is based upon the `scratchpad' diff created by Carlo. All MFE work prior to that point must be attributed to Fabio who ported and maintained Steve's original patch up to that time.

When release routines are called after device is disconnected, the attempts fail. fe drivers should avoid accessing the device, from their release interfaces when called from disconnect path. dvb-frontend maintains exit flag to keep track when fe device is disconnected in its private data structures. Export the flag in fe to enable drivers to check the device status from their release interfaces.

V4L/DVB (3673): Fix budget-av CAM reset Unfortunately on the budget-av board, the CAM reset line is tied to the frontend reset line, so resetting the CAM also zaps the frontend. This breaks the tda1004x at least, and causes it to fail to tune until the budget-av module is reloaded. This patch adds an exported function to dvb_frontend that allows a card to forcibly reinitialise a frontend. The budget-av now does this on CAM reset, which corrects this problem. since they do not tie the CAM reset line to the frontend reset line.

[media] dvb: document dvb_frontend_sleep_until() This function is used mainly at the DVB core, in order to provide emulation for a legacy ioctl. The only current exception is the stv0299 driver, with takes more than 8ms to switch voltage, breaking the emulation for FE_DISHNETWORK_SEND_LEGACY_CMD. Document that.

[PATCH] dvb: let other frontends support FE_DISHNETWORK_SEND_LEGACY_CMD Add support to FE_DISHNETWORK_SEND_LEGACY_CMD code to support other frontends besides stv0299. The generic code is a fallback in the case that it doesn't work for some specific frontends (again stv0299 being a good example).

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!
