Subject: [PATCH] crypto: move storage for grub_crypto_pk_* to crypto.c
|
|
|
|
The way gcry_rsa and friends (the asymmetric ciphers) are loaded for the
|
|
pgp module is a bit quirky.
|
|
|
|
include/grub/crypto.h contains:
|
|
extern struct gcry_pk_spec *grub_crypto_pk_rsa;
|
|
|
|
commands/pgp.c contains the actual storage:
|
|
struct gcry_pk_spec *grub_crypto_pk_rsa;
|
|
|
|
And the module itself saves to the storage in pgp.c:
|
|
GRUB_MOD_INIT(gcry_rsa)
|
|
{
|
|
grub_crypto_pk_rsa = &_gcry_pubkey_spec_rsa;
|
|
}
|
|
|
|
This is annoying: gcry_rsa now has a dependency on pgp!
|
|
|
|
We want to be able to bring in gcry_rsa without bringing in PGP,
|
|
so move the storage to crypto.c.
|
|
|
|
Previously, gcry_rsa depended on pgp and mpi. Now it depends on
|
|
crypto and mpi. As pgp depends on crypto, this doesn't add any new
|
|
module dependencies using the PGP verfier.
|
|
|
|
[FWIW, the story is different for the symmetric ciphers. cryptodisk
|
|
and friends (zfs encryption etc) use grub_crypto_lookup_cipher_by_name()
|
|
to get a cipher handle. That depends on grub_ciphers being populated
|
|
by people calling grub_cipher_register. import_gcry.py ensures that the
|
|
symmetric ciphers call it.]
