Jussi Kivilinna 341975bf3a crypto: serpent-sse2 - should select CRYPTO_CRYPTD
Since serpent_sse2_glue.c uses cryptd, CRYPTO_SERPENT_SSE2_X86_64 and
CRYPTO_SERPENT_SSE2_586 should be selecting CRYPTO_CRYPTD.

Kim Phillips c3e337f88a crypto: talitos - support for channel remap and 2nd IRQ
Some later SEC v3.x are equipped with a second IRQ line.
By correctly assigning IRQ affinity, this feature can be
used to increase performance on dual core parts, like the
MPC8572E and P2020E.

The existence of the 2nd IRQ is determined from the device
node's interrupt property.  If present, the driver remaps
two of four channels, which in turn makes those channels
trigger their interrupts on the 2nd line instead of the first.
To handle single- and dual-IRQ combinations efficiently,
talitos gets two new interrupt handlers and back-half workers.

[includes a fix to MCR_LO's address.]

Kim Phillips 5b859b6ebb crypto: talitos - be less noisy on startup
talitos prints every algorithm it registers at module load time.
Algorithms are being added that make for an excessively noisy console
(latest HMACs patch makes an SEC 3.1 print 20 lines).
Instead, display the SEC h/w version number, and inform the
user of algorithm registration status in /proc/crypto, like so:

talitos ffe30000.crypto: fsl,sec3.1 algorithms registered in /proc/crypto

Lee Nipper 79b3a418e0 crypto: talitos - add hmac algorithms
Add these hmac algorithms to talitos:
    hmac(md5),
    hmac(sha1),
    hmac(sha224),
    hmac(sha256),
    hmac(sha384),
    hmac(sha512).
These are all type ahash.

Signed-off-by: Lee Nipper <lee.nipper@gmail.com>

Fixed up to not register HMAC algorithms on sec2.0 devices.
Rationale (from Lee):

on an 8349E Rev1.1, there's a problem with hmac for any talitos
hmac sequence requiring an intermediate hash context (Pointer
DWORD 1); the result is an incorrect hmac.  An intermediate hash
context is required for something longer than (65536-blocksize),
and for other cases when update/finup/final are used inefficiently.
Interestingly, a normal hash (without hmac) works perfectly
when using an intermediate context.

Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler
functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations
in parallel to improve performance on out-of-order CPUs). Glue code is based
on one from AES-NI implementation, so requests from irq context are redirected
to cryptd.

v2:
 - add missing include of linux/module.h
   (appearently crypto.h used to include module.h, which changed for 3.2 by
    commit 7c926402a7)

Jarod Wilson 505172e11f crypto: ansi_cprng - enforce key != seed in fips mode
Apparently, NIST is tightening up its requirements for FIPS validation
with respect to RNGs. Its always been required that in fips mode, the
ansi cprng not be fed key and seed material that was identical, but
they're now interpreting FIPS 140-2, section AS07.09 as requiring that
the implementation itself must enforce the requirement. Easy fix, we
just do a memcmp of key and seed in fips_cprng_reset and call it a day.

v2: Per Neil's advice, ensure slen is sufficiently long before we
compare key and seed to avoid looking at potentially unallocated mem.

Jussi Kivilinna dd6eec242b crypto: serpent - rename module from serpent to serpent_generic
Rename module from serpent.ko to serpent_generic.ko and add module alias. This
is to allow assembler implementation to autoload on 'modprobe serpent'. Also
add driver_name and priority for serpent cipher.

Al Viro a3fbbde70a VFS: we need to set LOOKUP_JUMPED on mountpoint crossing
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.

Simple way to reproduce the problem in mainline:

    cat >/tmp/a.c <<'EOF'
    #include <unistd.h>
    #include <fcntl.h>
    #include <stdio.h>
    main()
    {
            struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
            if (fcntl(0, F_SETLK, &fl))
                    perror("setlk");
    }
    EOF
    cc /tmp/a.c -o /tmp/test

then on nfs4:

    mount --bind file1 file2
    /tmp/test < file1		# ok
    /tmp/test < file2		# spews "setlk: No locks available"...

What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.

The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks.  I.e.  set LOOKUP_JUMPED...

Mandeep Baines 0bdfea8ba8 forcedeth: Improve stats counters
Rx byte count was off; instead use the hardware's count.  Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.

- The count of transmitted packets reported by the forcedeth driver
  reports pre-TSO (TCP Segmentation Offload) packet counts and not the
  count of the number of packets sent on the wire. This change fixes
  the forcedeth driver to report the correct count. Fixed the code by
  copying the count stored in the NIC H/W to the value reported by the
  driver.

- Count rx_drop_frame errors as rx_fifo_errors:
  We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
  for too long.  Normally, rx_fifo_errors would be counted in this case.
  The rx_drop_frame error count is private to forcedeth and is not
  reported by ifconfig or sysfs.  The rx_fifo_errors count is currently
  unused in the forcedeth driver.  It is reported by ifconfig as overruns.
  This change reports rx_drop_frame errors as rx_fifo_errors.

david decotigny 4687f3f364 forcedeth: remove unneeded stats updates
Function ndo_get_stats() updates most of the stats from hardware
registers, making the manual updates un-needed. This change removes
these manual updates. Main exception is rx_missed_errors which needs
manual update.

Another exception is rx_packets, still updated manually in this commit
to make sure this patch doesn't change behavior of driver. This will
be addressed by a future patch.
