I'd assume it's not a hardware but, so my the assembly code doesn't like the debian toolchain? It's
       binutils 2.18.1~cvs20080103-7
       gcc 4.3.2-1
(all the Debian package versions)

You forgot to list the kernel version :)

The correct output should be

		.result = "\x69\xc4\xe0\xd8\x6a\x7b\x04\x30"
			  "\xd8\xcd\xb7\x80\x70\xb4\xc5\x5a",

Weird. I've got exactly the same versions as you, using yesterday's Linus git tree, and it works just fine on a Core 2 Quad Q6600. From /proc/crypto after boot:

name : aes
driver : aes-asm
module : aes_x86_64
priority : 200
refcnt : 1
selftest : passed
type : cipher
blocksize : 16
min keysize : 16
max keysize : 32

module : aes_generic
priority : 100
refcnt : 1
selftest : passed
type : cipher
blocksize : 16
min keysize : 16
max keysize : 32

Are you in 64-bit mode or legacy mode? I'm in 64.

I get the same error on 64-bit mode. If aes_x86_64 is compiled as module, everything is OK. But if it is compiled as built-in, the error message print during system boot. Because aes_x86_64 may be registered before aes_generic, but the tables used by AES have not been generated when aes_x86_64 is registered.

This can be resolved by the following patch. -------------------------------------------------------------------> Fix a bug of aes_x86_64, aes_generic initialization order issue.

If aes_x86_64 and aes_generic are compiled as builtin, the initialization order is undetermined. That is, aes_x86_64 may be initilized before aes_generic is initilized, but aes_x86_64 depends on tables generated in aes_generic initialization code. aes_x86_64 can not work before aes_generic is initialized, so that cause register time testing failed with following error message:

[    0.657034] alg: cipher: Test 1 failed on encryption for aes-asm
[    0.657111] 00000000: 00 01 02 03 04 05 06 07 08 08 08 08 08 08 08 08

This patch fixes this bug via making crypto_aes_gen_tabs public and invoking it in aes_x86_64 and aes_generic.

I think that is not easy. Not all architecture follow the same directory structure arch/<x>/crypto. And arch/x86/crypto is used by user mode linux too.

Right, relying on link order is hazardous.

However, since the table isn't that large we might as well compute it once and for all, like this:

crypto: aes - Precompute tables

The tables used by the various AES algorithms are currently computed at run-time. This has created an init ordering problem because some AES algorithms may be registered before the tables have been initialised.

This patch gets around this whole thing by precomputing the tables.

I think that is not easy. Not all architecture follow the same directory structure arch/<x>/crypto. And arch/x86/crypto is used by user mode linux too.
Right, relying on link order is hazardous.

You don't have to trick with Makefiles. You could use subsys_initcall() in cryptomgr & algapi and for instance rootfs_initcall() for the generic aes to ensure that it comes before the asm version but after the subsystem. _Or_ you could use late_initcall() in the asm version. After a second look I thing the late initcall variant looks better.

Quoted 4 lines

However, since the table isn't that large we might as well compute it once and for all, like this:
crypto: aes - Precompute tables

That patch is "big" but should not break anything. I still prefer to fix it the other way via the init call order: it is smaller patch and would be a nice example for further modules which might rely on each other like aes does.

No matter what you pick as your final solution, should I send a 's/module_init/subsys_initcall/' patch for cryptomgr & algapi?

cryptomgr already uses subsys_initcall and algapi doesn't need it yet because it only registers the proc entry.

Cheers,
