tipc: Increase buffer header to support worst-case device

2008-05-09T04:38:24Z

This patch increases the headroom TIPC reserves in each sk_buff to accommodate the largest possible link level device header. Signed-off-by: Allan Stephens Signed-off-by: David S. Miller

net: Fix wrong interpretation of some copy_to_user() results.

2008-04-25T08:49:48Z

I found some places, that erroneously return the value obtained from the copy_to_user() call: if some amount of bytes were not able to get to the user (this is what this one returns) the proper behavior is to return the -EFAULT error, not that number itself.

[TIPC]: Cleanup of TIPC reference table code

2008-04-17T01:22:20Z

This patch is a largely cosmetic cleanup of the TIPC reference table code. - The object reference field in each table entry is now single 32-bit integer instead of a union of two 32-bit integers. - Variable naming has been made more consistent. - Error message output has been made more consistent. - Useless #includes have been eliminated.

[TIPC]: Optimized initialization of TIPC reference table

2008-04-17T01:21:47Z

This patch modifies TIPC's reference table code to delay initializing table entries until they are actually needed by applications. Signed-off-by: Allan Stephens Signed-off-by: David S. Miller

[TIPC]: Remove inlining of reference table locking routines

2008-04-17T01:21:16Z

This patch converts the TIPC reference table locking routines into non-inlined routines, since they are mainly called from non-performance critical areas of TIPC and the added code footprint incurred through inlining can no longer be justified.

[TIPC]: Enhance validation of format on incoming messages

2008-04-16T02:04:54Z

This patch ensures that TIPC properly handles incoming messages that have incorrect or unexpected formats. Most significantly, it now ensures that each sl_buff has at least as much data as the message header indicates it should, and that the entire message header is stored contiguously; this prevents TIPC from accidentally accessing memory that is not part of the sk_buff.

[TIPC]: Force linearization of non-linear sk_buffs

2008-04-16T02:03:23Z

This patch allows TIPC to process incoming messages that are stored in a fragmented sk_buff, by forcing the linearization of any such messages it receives. Note: This is an interim solution to allow TIPC to operate with Ethernet devices that generate non-linear buffers (such as the gianfar driver), until such time as the rest of TIPC is enhanced to handle sk_buffs with multiple data areas.

[TIPC]: Use fast buffer cloning to improve performance

2008-04-16T02:02:30Z

This patch causes TIPC to allocate fast clonable sk_buffs, rather than standard ones. This speeds up the cloning operation done by the link code each time a message is sent off-node. Signed-off-by: Allan Stephens Signed-off-by: David S. Miller

[TIPC]: Remove redundant NULL check when discarding buffers

2008-04-16T02:01:43Z

This patch eliminates a null pointer check when discarding a TIPC message buffer, since kfree_skb() already handles this situation. Acknowledgements to Florian Westphal (fw@strlen.de> for suggesting this enhancement. Signed-off-by: Allan Stephens Signed-off-by: David S. Miller
