[SCTP]: Allow spillover of receive buffer to avoid deadlock.

2006-05-06T00:02:09+00:00

This patch fixes a deadlock situation in the receive path by allowing
temporary spillover of the receive buffer.

- If the chunk we receive has a tsn that immediately follows the ctsn,
  accept it even if we run out of receive buffer space and renege data with
  higher TSNs.
- Once we accept one chunk in a packet, accept all the remaining chunks
  even if we run out of receive buffer space.

[NET]: {get|set}sockopt compatibility layer

2006-03-21T06:45:21+00:00

This patch extends {get|set}sockopt compatibility layer in order to
move protocol specific parts to their place and avoid huge universal
net/compat.c file in the future.

[SCTP]: Fix 'fast retransmit' to send a TSN only once.

2006-02-03T00:57:31+00:00

SCTP used to "fast retransmit" a TSN every time we hit the number
of missing reports for the TSN.  However the Implementers Guide
specifies that we should only "fast retransmit" a given TSN once.
Subsequent retransmits should be timeouts only. Also change the
number of missing reports to 3 as per the latest IG(similar to TCP).

[SCTP]: Fix machine check/connection hang on IA64.

2006-01-17T19:55:57+00:00

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.

2006-01-17T19:55:17+00:00

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.

2006-01-17T19:52:12+00:00

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.
