The following patch series adds support for partial (de)compression to the
CRYPTO API, and modifies SquashFS 4 to use this:
[1] crypto: testmgr - Correct comment about deflate parameters
[2] crypto: compress - Add pcomp interface
[3] crypto: testmgr - Add support for the pcomp interface
[4] crypto: api - Add type init function to crypto_tfm
[5] crypto: api - Export pcomp through comp
[6] crypto: deflate - switch to pcomp
[7] crypto: testmgr - swith deflate test to pcomp
[8] squashfs: Make SquashFS 4 use the new pcomp crypto interface
All patches are relative to cryptodev-2.6.git, except for the last one, which
is relative to squashfs-2.6.git.
The first patch is independent and can be applied immediately, but I included
it in this series to avoid rejects.
The backwards-compatibility layer has been tested with IPComp and UBIFS.
Changes since last version (2008-11-24):
- Add a new "pcomp" crypto interface, instead of modifying the existing
"comp" interface, with a compatibility layer,
- Modify the existing "deflate" module, instead of adding a new "zlib"
module,
- Add support for the configuration of (de)compression parameters,
- Separate allocation for compression and decompression, to avoid memory
wastage.
Thanks for your comments!
