net: Compute protocol sequence numbers and fragment IDs using MD5.

2011-08-07T01:33:19+00:00

Computers have become a lot faster since we compromised on the
partial MD4 hash which we use currently for performance reasons.

MD5 is a much safer choice, and is inline with both RFC1948 and
other ISS generators (OpenBSD, Solaris, etc.)

Furthermore, only having 24-bits of the sequence number be truly
unpredictable is a very serious limitation.  So the periodic
regeneration and 8-bit counter have been removed.  We compute and
use a full 32-bit sequence number.

For ipv6, DCCP was found to use a 32-bit truncated initial sequence
number (it needs 43-bits) and that is fixed here as well.

tpm_tis: fix build when ACPI is not enabled

2011-08-04T00:25:21+00:00

Fix tpm_tis.c build when CONFIG_ACPI is not enabled by providing a stub
function.  Fixes many build errors/warnings:

  drivers/char/tpm/tpm_tis.c:89: error: dereferencing pointer to incomplete type
  drivers/char/tpm/tpm_tis.c:89: warning: type defaults to 'int' in declaration of 'type name'
  drivers/char/tpm/tpm_tis.c:89: error: request for member 'list' in something not a structure or union

ramoops: update module parameters

2011-08-04T00:25:21+00:00

Update the module parameters when platform data is used.  This means
that they can be read from /sys/module/ramoops/parameters in order to
parse the memory area.

ramoops: fix compile failure on parisc

2011-07-30T06:41:09+00:00

Fixes this:

  drivers/char/ramoops.c: In function 'ramoops_init':
  drivers/char/ramoops.c:221: error: implicit declaration of function 'IS_ERR'
  drivers/char/ramoops.c:222: error: implicit declaration of function 'PTR_ERR'

If it actually builds on other platforms, it's probably getting
linux/err.h via some other #include.

And stop referring to Victoria Falls, as the attribute we're
talking about is whether the rng is multi-unit capable which
applies to several chip variants now.

ramoops: make record_size a module parameter

2011-07-26T23:49:46+00:00

The size of the dump is currently set using the RECORD_SIZE macro which
is set to a page size.  This patch makes the record size a module
parameter and allows it to be set through platform data as well to allow
larger dumps if needed.
