The following patch series adds support for partial (de)compression to the
CRYPTO API, and modifies SquashFS 4 to use this:
[1] crypto: compress - Add pcomp interface
[2] crypto: testmgr - Add support for the pcomp interface
[3] crypto: new zlib crypto module, using pcomp
[4] crypto: testmgr - add zlib test
[5] squashfs: Make SquashFS 4 use the new pcomp crypto interface
The patches are based on:
linux-2.6.git + cryptodev-2.6.git + commit 3f683d61 ("crypto: api - Fix
crypto_alloc_tfm/create_create_tfm return convention")
Changes since last version (2009-02-13):
- Convert crypto_pcomp to a new-style crypto module, using crypto_alloc_tfm()
instead of crypto_alloc_base()
- Pass crypto_pcomp pointers instead of crypto_tfm pointers where appropriate
- Use crypto_destroy_tfm() instead of crypto_free_tfm(), to take into account
the offset info the slab object
- Remove redundant check for CRYPTO_ALG_TYPE_PCOMPRESS in
crypto_pcomp_init_tfm()
- Use separate setup functions for compression and decompression
- Sanitize naming to crypto_{,de}compress_{setup,init,update,final}()
- Remove backwards-compatibility layer (export pcomp through comp), as
requested by Herbert Xu
- Create a new "zlib" pcomp module instead of modifying the existing
"deflate" comp module
- Readd accidentally removed ".cra_module = THIS_MODULE", which allowed the
zlib module to be rmmoded while it was in use
- Fix the pcomp/testmgr dependency
