This means linux/types.h is no longer implicitly included, so add an include of uapi/linux/types.h to linux/cryptohash.h for __u32. Other users of cryptohash.h cannot be affected, since they must already have been including uapi/linux/types.h in order for gcc not to complain about unknown types.

lib/sha1: use the git implementation of SHA-1 2011-08-06T18:26:52+00:00 Mandeep Singh Baines msb@chromium.org 2011-08-06T01:46:27+00:00 1eb19a12bd2214cdcad5273d472b062a4ba97fa1 For ChromiumOS, we use SHA-1 to verify the integrity of the root filesystem.

For ChromiumOS, we use SHA-1 to verify the integrity of the root
filesystem.  The speed of the kernel sha-1 implementation has a major
impact on our boot performance.

To improve boot performance, we investigated using the heavily optimized
sha-1 implementation used in git.  With the git sha-1 implementation, we
see a 11.7% improvement in boot time.

10 reboots, remove slowest/fastest.

Before:

  Mean: 6.58 seconds Stdev: 0.14

After (with git sha-1, this patch):

  Mean: 5.89 seconds Stdev: 0.07

The other cool thing about the git SHA-1 implementation is that it only
needs 64 bytes of stack for the workspace while the original kernel
implementation needed 320 bytes.

Define hashing size constants specific to TCP cookies.

Add new function: tcp_cookie_generator().

Linux RCU technique appears to be well-suited to this application, though
neither of the circular queue items are freed.

Initial git repository build. I'm not bothering with the full history,

git days unnecessarily complicated, when we don't have a lot of good
