history

这是一个LINUX环境的 VDR 插件源代码,可支持Irdeto, Seca, Viaccess, Nagra, Conax & Cryptoworks等CA系统的读卡、共享等操作。

  keyfile. A quick upgrade guide:
  N xxxx 10   ->   N xxxx 01
  N xxxx 02   ->   N xxxx NN 02
  N xxxx N2   ->   N xxxx NN 12
  verify keys ->   N xxxx V
              ->   N xxxx NN 03
- Restructured AutoUpdate code. EMM data is now passed to all systems which can
  handle it, concurrent recordings doesn't cause multiple processing of the same
  date and it's possible to log on all available CAIDs concurrently (though this
  may cause high CPU load). See plugin setup menu. Option LoggerActive has been
  renamed to AutoUpdate. Option LoggerTimeout has been removed. Check your
  config.
- Added some statistics about EMM packet load.
- Now using non-RSA (i.e. plain) camkey challenge for Irdeto smartcards if the
  word PLAIN is given in smartcard.conf instead of a certificate. See example
  smartcard.conf. For ACS 0383/0384 cards the challenge type is autodetected. If
  anybody knows a generic way to detect the challenge type, please let us know.
- Fixed several crypto classes to be reentrant (fixing possible race in
  multi-threaded ECM/EMM handling).
- Fixed access to (possibly) deleted filter class in section filter handling. 
- Fixed complaining about erroneous entries in smartcard.conf if compiled
  without SC_IRDETO.
- Fixed endless loop in SimpleList handling.
- Fixed vdr-1.3.38-sc patch (one hunk was lost).

08.01.2006: Version 0.5.4
- Added a plugin SVDR interface. The only command is RELOAD for now (triggers a
  reload of the configuration files).
- Added support for multiple TPS keys (key is selected based on Viaccess hash).
- Added premiliary support for Nagra2 AU. See example keyfile for format of
  needed keys. Key format is subject to change in next releases.
- Complete rewrite of the Seca2 provider specific code.
- Added generic RSA & IDEA crypto classes.
- Added better checking of CW decryption status in smartcard Cryptoworks.
- General code review (eliminated duplicate code, replaced VDR base classes by
  own shorter ones, beautified code).
- Now generating smartcard Irdeto info string for OSD card menu.
- If the DVB driver doesn't support the CA_SET_PID ioctl call (i.e. unpatched
  driver), auto adjust the FF concurrent limit to 1.
- Fixed checking card status in smartcard Irdeto camkey exchange.
- Fixed detaching a PID from a handler if VDR has removed this PID from the
  channels.conf entry meanwhile.
- Fixed ECM table handling in ca.cache.
- Fixed Nagra2 CW order for D+.
- Fixed a gcc4.1 compiling issue.
- Added additional debug output in cardclient camd35 to snoop for AU problems.
  You may comment DEBUG_EXTRA to disable verbose log.
- Updated FFdecsa patch to 0.1.3 (fixing a race condition).
- Note: this release was forced by the release of VDR 1.3.38 and not all of the
  changes above are tested as well as they should be.

09.12.2005: Version 0.5.3
- Added Nagra2 EMM support and EMM caching to cardclient newcamd.
- Added Cryptoworks EMM support and EMM caching to cardclient camd35.
- You may now add multiple CAID fields to cardclient.conf. A valid line would be
  e.g. camd35:192.168.0.1:20248:1/1702/FF00,0604,0d0c/FF00:hero:itsme
- Added support for systems which broadcast ECM on tables other than 0x80/0x81.
- Added support for Nagra2 BEV & dual IDEA opkeys (00/10).
- Now reading CAID from Cryptoworks smartcard.
- Added sanity check to nano sorting to prevent memory trashing.
- Added new CAID nano to cardclient Radegast ECM request.
- Fixed Cryptoworks shared EMM parsing. Added additional checks to reduced EMM
  load too.
- Fixed smartcard Irdeto camkey challenge for Premiere S01 and other non-Z
  cards. As these cards don't support the RSA challenge, you don't need a
  certificate for them.
- Fixed matching Irdeto certificates which are given with ACS version only.
- Fixed misleading error messages in smartcard.conf parser.
- Fixed ECM-EMM caid mismatch and segfault due to leftover debug statements in
  cardclient camd35.
- Fixed (i.e. removed) global cardclient EMM cache as it corrupts EMM merging
  for systems which broadcast shared updates on different tables.
- Fixed cardclient newcamd segfault on bad config data.

12.11.2005: Version 0.5.2
- Introducing a new config file for smartcard specific data e.g. RSA certificate
  or box keys. The file is called smartcard.conf. See the example file.
- Added support for full camkey challenge in smartcard Irdeto. You need a RSA
  certificate matching your card (either Irdeto default or card specific one) in
  smartcard.conf or your card won't work!
- Added an abstract layer to parse and assemble EMM messages. This touches
  several systems e.g. Viaccess, Cryptoworks & NDS. A bug here may break them
  all.
- Added Cryptoworks & Viaccess EMM handling to newcamd cardclient (via new
  assemble code).
- Added some more MAP math calls to Nagra emulation to fix Rom10 AU.
- Several fixes to NDS EMM parsing/assembling.
- Fixed ConstCW key lookup (was broken due to Nagra1/2 key handling changes).
- Fixed cardclient camd3 to include SID in ECM request.
- Fixed cardclient newcamd to handle NULL-cw which are send by newcs.
- Removed logger option 'non-recording on' from the config. In 0.5.x it is
  without function anyways.
- Added a message to hint the user about unusual values in ScCaps. Changed the
  default values to something more reasonable too.
- Updated FFdecsa patch to 0.1.2 (fixing a segfault).

13.10.2005: Version 0.5.1
- Added smartcard Cryptoworks EMM handling. There is a setup option to disable
  the parental rating on the card too (experimental). Thanks to scotty for the
  sample code.
- Added smartcard Viaccess EMM handling (experimental).
- Added FFdecsa-0.1.1 patch.
- Don't count a live stream on a FF card when deciding about allowed
  concurrency. A live stream doesn't use bandwidth on the bus.
- Apply min. ECM processing time to Nagra2 too.
- Fixed segfault for Seca1.
- Fixed Irdeto key updates. Somehow/sometime the code was broken.
- Fixed cardclient newcamd NDS EMM (still experimental).
- Now considering the key size when superseding keys.
- Forgot to mention that you need additional table files for Seca 6a (s2_sse.bin
  5120; s2_sse_006a.bin 336; s2_cw_006a.bin 512 (Numbers are the filesize)).
- Updated finnish translations.

15.09.2005: Version 0.5.0
- Forked development branch.
- Added concurrent recording feature i.e. record/view multiple encrypted
  channels on a single DVB card. This also works on a full-featured DVB card!
  To make this feature work you NEED:
  on a BUDGET card:
    * SoftCSA version 0.1.0 or greater
  on a FULL-FEATURED card:
    * a DVB driver patched with dvb-cwidx.diff
    * a specialy patched firmware. The "normal" patched firmware doesn't work!
  See further details in the README.
- vdr-sc patch has been updated. This plugin version ONLY works with this patch!
  Older plugin versions doesn't work with this patch, although they may compile
  fine!
- Dropped compatibility for older VDR versions. Requires VDR version 1.3.29 or
  newer.
- Changed card & provider handling in cardclient camd35 (experimental).
- Added NDS support to newcamd cardclient (experimental).
- Added limited Seca 6a support.
- Fixed mismatching Nagra1 & Nagra2 keys.
