From 34edaa88324004baf4884fb0388f86059d9c4878 Mon Sep 17 00:00:00 2001 From: Tobias Diedrich Date: Mon, 16 Feb 2009 00:13:20 -0800 Subject: [PATCH 01/67] net: forcedeth: Fix wake-on-lan regression Commit f55c21fd9a92a444e55ad1ca4e4732d56661bf2e ("forcedeth: call restore mac addr in nv_shutdown path"), which was introduced to fix the regression tracked at http://bugzilla.kernel.org/show_bug.cgi?id=11358 causes the wake-on-lan mac to be reversed in the shutdown path. Apparently the forcedeth situation is rather messy in that the mac we need to writeback for a subsequent modprobe to work is exactly the reverse of what is needed for proper wake-on-lan. The following patch explains the situation in the comments and makes the call to nv_restore_mac_addr() conditional (only called if we are not really going for poweroff).

Miller" Date: Tue, 17 Feb 2009 21:24:05 -0800 Subject: [PATCH 02/67] net: Kill skb_truesize_check(), it only catches false-positives. A long time ago we had bugs, primarily in TCP, where we would modify skb->truesize (for TSO queue collapsing) in ways which would corrupt the socket memory accounting. skb_truesize_check() was added in order to try and catch this error more systematically. However this debugging check has morphed into a Frankenstein of sorts and these days it does nothing other than catch false-positives. Signed-off-by: David S.

So the timer is dequeued, the stats are read and then the timer is enqueued again. This is "okay" unless someone unloads the module. The locking here is also broken: mib_counters_update() grabs just a simple spinlock. The only thing the lock is good for is to protect the timer func against other callers namely mv643xx_eth_stop() && mv643xx_eth_get_ethtool_stats(). That means if the spinlock is taken via the ethtool path and than the timer kicks in then the box will lock up.

The v1.4 version of the firmware has been submitted to David Woodhouse for inclusion in the linux-firmware tree and it is already available at http://linuxwimax.org/Download. The reason for this change is that the 1.3 release of the user space software and firmware has a few issues that will make it difficult to use with currently deployed commercial networks such as Xohm and Clearwire. As well, the new 1.4 release of the user space software (which matches the 1.4 firmware) has intermitent issues with the 1.3 firmware. The 1.4 release in http://linuxwimax.org/Download has been widely deployed and tested with the codebase in 2.6.29-rc, the 1.4 firmware and the 1.4 user space components. We understand it is quite late in the rc process for such a change, but would like to ask for the change to be taken into consideration. Alternatively, a user could always force feed a 1.4 firmware into a driver that doesn't have this modification by: $ cd /lib/firmware $ mv i2400m-fw-usb-1.3.sbcf i2400m-fw-usb-1.3.real.sbcf $ ln -sf i2400m-fw-usb-1.4.sbc i2400m-fw-usb-1.3.sbcf Signed-off-by: Inaky Perez-Gonzalez Signed-off-by: David S.

One of its problems (besides ignoring the Orlov algorithm) is that it is a bit hyperactive about returning failure under suspicious circumstances. This can lead to spurious ENOSPC failures even when there are inodes still available. Work around this for now by retrying the search using find_group_other() if find_group_flex() returns -1. If find_group_other() succeeds when find_group_flex() has failed, log a warning message.

The implementation is a bare minimum to get encrypted channels to work in kaffeine. It works fine with my T/CI card. Now and then I get an AVC timeout and have to retune a channel in order to get it to work. Once the CAM seemed to hang so I needed to remove and insert it again. I.e. there are a number of glitches. The latest version contains the following changes: - Implemented the new hpsb iso interface so that data can be received from the card - Reduced some timers for demux setup which caused scanning to timeout - Added possibility to unload driver - Added support for getting C/N ratio - Added two debug parameters to the driver; ca_debug and avc_comm_debug. - Added CI support that works for me in kaffeine - Started working on CI MMI support. It now supports: o Enter menu o Receiving MMI objects - Added support for 64-bit platforms - Corrected DVB-C modulations problems Signed-off-by: Henrik Kurelid Signed-off-by: Stefan Richter (rebased, whitespace) --- drivers/media/dvb/firesat/Makefile | 1 + drivers/media/dvb/firesat/avc_api.c | 768 ++++++++++++++++++----- drivers/media/dvb/firesat/avc_api.h | 296 +++++---- drivers/media/dvb/firesat/cmp.c | 40 +- drivers/media/dvb/firesat/firesat-ci.c | 346 ++++++++-- drivers/media/dvb/firesat/firesat.h | 174 ++++- drivers/media/dvb/firesat/firesat_1394.c | 123 +--- drivers/media/dvb/firesat/firesat_dvb.c | 49 +- drivers/media/dvb/firesat/firesat_fe.c | 80 ++- drivers/media/dvb/firesat/firesat_iso.c | 106 ++++ 10 files changed, 1488 insertions(+), 495 deletions(-) create mode 100644 drivers/media/dvb/firesat/firesat_iso.c diff --git a/drivers/media/dvb/firesat/Makefile b/drivers/media/dvb/firesat/Makefile index fdf86870f1fd..be7701b817c9 100644 --- a/drivers/media/dvb/firesat/Makefile +++ b/drivers/media/dvb/firesat/Makefile @@ -1,6 +1,7 @@ firesat-objs := firesat_1394.o \ firesat_dvb.o \ firesat_fe.o \ + firesat_iso.o \ avc_api.o \ cmp.o \ firesat-rc.o \ diff --git a/drivers/media/dvb/firesat/avc_api.c b/drivers/media/dvb/firesat/avc_api.c index cd79c806ecc7..273c7235dd90 100644 --- a/drivers/media/dvb/firesat/avc_api.c +++ b/drivers/media/dvb/firesat/avc_api.c @@ -3,6 +3,7 @@ * * Copyright (c) 2004 Andreas Monitzer * Copyright (c) 2008 Ben Backx + * Copyright (c) 2008 Henrik Kurelid * * This program is free software;

Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables... Sun, 24 Aug 2008 23:26:23 +0200 (CEST) firesat: add missing copyright notes Reported by Andreas Monitzer and Christian Dolzer.

Use hardware memory barriers on systems which need them. (Of course a full fix of generation handling would require much more than this. The ieee1394 core's bus generation counter had to be tied to the controller's bus generation counter; cf. Kristian's stack. It's just that I have other current business with the code around these barrier()s, so why not do at least this small fix.)

This affects the new firedtv driver which is meant to be auto-loaded and matched only for vendor-specific devices. We now always copy ne->vendor_id into ud->vendor_id before we scan a unit directory (and fill in a possibly present vendor ID from there). This way, the root directory's vendor ID is used as fallback in the "uevent" environment for modprobe'ing per module alias when a node was plugged in, and in the driver match routine when protocol drivers are bound to unit directories. It will however not be used as sysfs attribute of a unit directory device.

Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include instead of because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code.

So bring it back in an updated form with only 60% of the original code footprint. Logging can be enabled with # echo -1 > /sys/module/firedtv/parameters/debug 1 instead of -1 enables only FCP header logging, 2 instead of -1 enables only hexdumps of the entire FCP frames. 0 switches logging off again. Fri, 20 Feb 2009 20:54:27 +0100 (CET) firedtv: build fix for INPUT=m and DVB_FIREDTV=y Thu, 19 Feb 2009 20:40:39 +0100 firedtv: use msecs_to_jiffies Pointed out by Mauro Carvalho Chehab. Sun Feb 15 20:50:46 CET 2009 firedtv: some more housekeeping Fix an old checkpatch warning and a new compiler warning. Sun Feb 15 15:33:17 CET 2009 firedtv: rename a file once more At the moment, about a third of avc.c is specific to FireDTVs rather than generic AV/C code. Rename it to firedtv-avc.c. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: more compact channels backing store Replace struct firedtv_channel { bool active; int pid; } channel[16]; by unsigned long channel_active; u16 channel_pid[16];. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: some simplifications c->active was unnecessarily cleared twice. Also, by marking the channel inactive before the for loop, the loop becomes identical with fdtv_channel_collect(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: remove a bogus loop This loop is unnecessary because - only active channel[].pid's will be sent to the device, - when a channel is activated, its pid is set to dvbdmxfeed->pid. Perhaps the original code was there because it was initially not fully covered by the fdtv->demux_mutex. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix mutex protection fdtv_start_feed() accessed the channel list unsafely. Fully serialize it with itself and fdtv_stop_feed(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix missing braces Original code was: ... case DMX_TS_PES_OTHER: //Dirty fix to keep firesat->channel pid-list up to date for(k=0;k<16;k++){ if(firesat->channel[k].active == 0) firesat->channel[k].pid = dvbdmxfeed->pid; break; } channel = firesat_channel_allocate(firesat); break; default: ... Looks bogus in several respects. For now let's just add braces to the if because that seems to be what the author meant. Sun Feb 15 15:33:17 CET 2009 firedtv: allow build without input subsystem !CONFIG_INPUT is very unlikely on systems on which firedtv is of interest. But we can easily support it. Sun Feb 15 15:33:17 CET 2009 firedtv: replace EXTRA_CFLAGS by ccflags The former are deprecated. The latter can depend on Kconfig variables. Sun Feb 15 15:33:17 CET 2009 firedtv: concentrate ieee1394 dependencies Move the entire interface with drivers/ieee1394 to firedtv-1394.c. Move 1394-independent module initialization code to firedtv-dvb.c. This prepares interfacing with drivers/firewire. Sun Feb 15 15:33:17 CET 2009 firedtv: amend Kconfig menu prompt Sun Feb 15 15:33:17 CET 2009 firedtv: remove kernel version compatibility macro Sun Feb 15 15:33:17 CET 2009 firedtv: combine header files avc.h and firedtv-*.h are small and currently not shared with other drivers, hence concatenate them all into firedtv.h. Sun Feb 15 15:33:17 CET 2009 firedtv: misc style touch-ups Standardize on lower-case hexadecimal constants. Adjust whitespace. Omit unnecessary pointer type casts and an unnecessary list head initialization. Use dev_printk. Wed Feb 11 21:21:04 CET 2009 firedtv: avc, ci: remove unused constants Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from read descriptor response operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from DSD command operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: header file cleanup Remove unused constants and declarations. Move privately used constants into .c files. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from FCP frame types Don't use bitfields in struct types of on-the-wire data. Also move many privately used constants from avc.h to avc.c and remove some unused constants. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: fix offset in avc_tuner_get_ts The parentheses were wrong. It didn't matter though because this code only writes a 0 into an area which is already initialized to 0. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: reduce stack usage, remove two typedefs It is safe to share a memory buffer for command frame and response frame because the response data come in after the command frame was last used. Even less stack would be required if only the actual required frame size instead of the entire FCP register size was allocated. Also, rename the defined types AVCCmdFrm and AVCRspFrm to struct avc_command_frame and struct avc_response_frame. TODO: Remove the bitfields in these types.

Signed-off-by: Beat Michel Liechti Change by Stefan R: combine it with case case FIREDTV_DVB_S as originally suggested by Beat Michel. This enables FE_CAN_FEC_AUTO also for FireDTV-S2 devices which is possible as long as only DVB-S channels are used. FE_CAN_FEC_AUTO would be wrong for DVB-S2 channels, but those cannot be used yet since the driver is not yet converted to S2API.

The code doesn't check whether the memtest parameter value exceeds the maximum pattern number. Instead the memtest code pretends to test with non-existing patterns, e.g. when booting with memtest=10 I've observed the following ... early_memtest: pattern num 10 0000001000 - 0000006000 pattern 0 ... 0000001000 - 0000006000 pattern 1 ... 0000001000 - 0000006000 pattern 2 ... 0000001000 - 0000006000 pattern 3 ... 0000001000 - 0000006000 pattern 4 ... 0000001000 - 0000006000 pattern 5 ... 0000001000 - 0000006000 pattern 6 ... 0000001000 - 0000006000 pattern 7 ... 0000001000 - 0000006000 pattern 8 ... 0000001000 - 0000006000 pattern 9 ... But in fact Linux didn't test anything for patterns > 4 as the default case in memtest() is to leave the function. I suggest to use the memtest parameter as the number of tests to be performed and to re-iterate over all existing patterns.
