| * crypto: mv_cesa - fix hashing of chunks > 1920 bytesPhil Sutter2011-11-211-5/+7
| | | | | | | | | | | | | | | | | | | | | | This was broken by commit 7759995c75ae0cbd4c861582908449f6b6208e7a (yes, myself). The basic problem here is since the digest state is only saved after the last chunk, the state array is only valid when handling the first chunk of the next buffer. Broken since linux-3.0.

* | crypto: talitos - handle descriptor not found in error pathKim Phillips2011-10-211-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CDPR (Current Descriptor Pointer Register) can be unreliable when trying to locate an offending descriptor. Handle that case by (a) not OOPSing, and (b) reverting to the machine internal copy of the descriptor header in order to report the correct execution unit error. Note: printing all execution units' ISRs is not effective because it results in an internal time out (ITO) error and the EU resetting its ISR value (at least when specifying an invalid key length on an SEC 2.2/MPC8313E).

* | crypto: padlock-aes - Make module loading even quieter when hardware is missingJonathan Nieder2011-08-031-3/+1
|/ | | | | | | | | | | | | | | | | | When loading aes via the module alias, a padlock module failing to load due to missing hardware is not particularly notable. With v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter when hardware isn't available, 2008-07-03), the padlock-aes module suppresses the relevant messages when the "quiet" flag is in use; but better to suppress this particular message completely, since the administrator can already distinguish such errors by the absence of a message indicating initialization failing or succeeding. This avoids occasional messages in syslog of the form padlock_aes: VIA PadLock not detected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.
