      firedtv: dvb_frontend_info for FireDTV S2, fix "frequency limits undefined" error · e73bf9f1
      Beat Michel Liechti authored
      I found that the function fdtv_frontend_init in the file firedtv-fe.c was
      missing a case for FIREDTV_DVB_S2 which resulted in "frequency limits
      undefined" errors in syslog.

      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.

      firedtv: reinstate debug logging option
      
          Henrik Kurelid tells me that FCP debug logging (which I removed during
          cleanups) is still useful when working on driver issues together with
          end users.  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.

      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.

      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.

      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.

      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.

      There was a bug causing the initialization to fail if adapter number was

          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).

      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 <asm/byteorder.h> instead of <linux/byteorder.h>
          because drivers/ieee1394/*.h also include the former.  I will fix this
          in drivers/ieee1394 and firedtv later.

      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.

          	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.

      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.

      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.

          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.

      hpsb_read, hpsb_write, hpsb_lock are sleeping functions which nobody is

      ieee1394: inherit ud vendor_id from node vendor_id · 9c939e4d
      Stefan Richter authored
      While Module_Vendor_ID in the configuration ROM's root directory is
      mandatory, there often aren't vendor IDs in unit directories.  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.

      These will be used by the firedtv driver.  Like hpsb_node_write() they
      are much better APIs for high-level drivers than hpsb_write() and its
      siblings --- easier to use correctly and also terser.
      
      Unlike hspb_node_write(), the two new functions will only be used by
      one call site.  Hence make them static inline instead of exported
      symbols.

      ieee1394: use correct barrier types between accesses of nodeid and generation · 29f8ea8a
      Stefan Richter authored
      A compiler barrier (explicit on the read side, implicit on the write
      side) is not quite enough for what has to be accomplished here.  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.)

      firedtv: fix remote control input
      
          and update the scancode-to-keycode mapping to a current model.  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.

      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.

      firesat: update isochronous interface, add CI support · df4846c3
      Henrik Kurelid authored
      I have finally managed to get the CI support for the card working. 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

      selinux: Fix the NetLabel glue code for setsockopt() · 09c50b4a
      Paul Moore authored
      At some point we (okay, I) managed to break the ability for users to use the
      setsockopt() syscall to set IPv4 options when NetLabel was not active on the
      socket in question.  The problem was noticed by someone trying to use the
      "-R" (record route) option of ping:
      
       # ping -R 10.0.0.1
       ping: record route: No message of desired type
      
      The solution is relatively simple, we catch the unlabeled socket case and
      clear the error code, allowing the operation to succeed.  Please note that we
      still deny users the ability to override IPv4 options on socket's which have
      NetLabel labeling active; this is done to ensure the labeling remains intact.
