      [SCTP]: Fix machine check/connection hang on IA64. · 313e7b4d
      由 Vlad Yasevich 提交于 
      sctp_unpack_cookie used an on-stack array called digest as a result/out
parameter in the call to crypto_hmac. However, hmac code
(crypto_hmac_final)
assumes that the 'out' argument is in virtual memory (identity mapped
region)
and can use virt_to_page call on it.  This does not work with the on-stack
declared digest.  The problems observed so far have been:
 a) incorrect hmac digest
 b) machine check and hardware reset.

Solution is to define the digest in an identity mapped region by
kmalloc'ing
it.  We can do this once as part of the endpoint structure and re-use it
when
verifying the SCTP cookie.

      [SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs. · 8116ffad
      由 Vlad Yasevich 提交于 
      Change all the structure members that hold jiffies to be of type
unsigned long.  This also corrects bad sysctl formating on 64 bit
architectures.

      [SCTP]: Fix sctp_cookie alignment in the packet. · 9834a2bb
      由 Vlad Yasevich 提交于 
      On 64 bit architectures, sctp_cookie sent as part of INIT-ACK is not
aligned on a 64 bit boundry and thus causes unaligned access exceptions.

The layout of the cookie prameter is this:
|<----- Parameter Header --------------------|<--- Cookie DATA --------
-----------------------------------------------------------------------
| param type (16 bits) | param len (16 bits) | sig [32 bytes] | cookie..
-----------------------------------------------------------------------

The cookie data portion contains 64 bit values on 64 bit architechtures
(timeval) that fall on a 32 bit alignment boundry when used as part of
the on-wire format, but align correctly when used in internal
structures.  This patch explicitely pads the on-wire format so that
it is properly aligned.

      [PATCH] Eliminate __attribute__ ((packed)) warnings for gcc-4.1 · 6a878184
      由 Jan Blunck 提交于 
      Since version 4.1 the gcc is warning about ignored attributes. This patch is
using the equivalent attribute on the struct instead of on each of the
structure or union members.

GCC Manual:
  "Specifying Attributes of Types

   packed
    This attribute, attached to struct or union type definition, specifies
    that
    each member of the structure or union is placed to minimize the memory
    required. When attached to an enum definition, it indicates that the
    smallest integral type should be used.

    Specifying this attribute for struct and union types is equivalent to
    specifying the packed attribute on each of the structure or union
    members."
