2015-02-13lib/halfmd4.c: simplify includesRasmus Villemoes1-0/+2
We only need EXPORT_SYMBOL, so compiler.h and export.h suffice. 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.

We are going to use this for TCP/IP sequence number and fragment ID generation. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-08-06lib/sha1: use the git implementation of SHA-1Mandeep Singh Baines1-1/+1
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.

2009-12-03TCPCT part 1b: generate Responder Cookie secretWilliam Allen Simpson1-0/+1
Define (missing) hash message size for SHA1. Define hashing size constants specific to TCP cookies. Add new function: tcp_cookie_generator(). Maintain global secret values for tcp_cookie_generator(). This is a significantly revised implementation of earlier (15-year-old) Photuris [RFC-2522] code for the KA9Q cooperative multitasking platform. Linux RCU technique appears to be well-suited to this application, though neither of the circular queue items are freed. These functions will also be used in subsequent patches that implement additional features.

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+12
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
