[NET]: Add a dev_ioctl() fallback to sock_ioctl()

2006-01-03T22:18:33+00:00

Currently all network protocols need to call dev_ioctl as the default
fallback in their ioctl implementations.  This patch adds a fallback
to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD.
This way all the procotol ioctl handlers can be simplified and we don't
need to export dev_ioctl.

[NET]: move struct proto_ops to const

2006-01-03T21:11:15+00:00

I noticed that some of 'struct proto_ops' used in the kernel may share
a cache line used by locks or other heavily modified data. (default
linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
least)

This patch makes sure a 'struct proto_ops' can be declared as const,
so that all cpus can share all parts of it without false sharing.

This is not mandatory : a driver can still use a read/write structure
if it needs to (and eventually a __read_mostly)

I made a global stubstitute to change all existing occurences to make
them const.

This should reduce the possibility of false sharing on SMP, and
speedup some socket system calls.

[APPLETALK]: Fix broadcast bug.

2005-09-27T23:11:29+00:00

From: Oliver Dawid 

we found a bug in net/appletalk/ddp.c concerning broadcast packets. In 
kernel 2.4 it was working fine. The bug first occured 4 years ago when 
switching to new SNAP layer handling. This bug can be splitted up into a 
sending(1) and reception(2) problem:

Sending(1)
In kernel 2.4 broadcast packets were sent to a matching ethernet device 
and atalk_rcv() was called to receive it as "loopback" (so loopback 
packets were shortcutted and handled in DDP layer).

When switching to the new SNAP structure, this shortcut was removed and 
the loopback packet was send to SNAP layer. The author forgot to replace 
the remote device pointer by the loopback device pointer before sending 
the packet to SNAP layer (by calling ddp_dl->request() ) therfor the 
packet was not sent back by underlying layers to ddp's atalk_rcv().

Reception(2)
In atalk_rcv() a packet received by this loopback mechanism contains now 
the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong) 
remote ethernet device pointer) and therefor no matching socket will be 
found to deliver this packet to. Because a broadcast packet should be 
send to the first matching socket (as it is done in many other protocols 
(?)), we removed the network comparison in broadcast case.

Below you will find a patch to correct this bug. Its diffed to kernel 
2.6.14-rc1

[TCP]: Move the tcp sock states to net/tcp_states.h

2005-08-29T22:41:54+00:00

Lots of places just needs the states, not even linux/tcp.h, where this
enum was, needs it.

This speeds up development of the refactorings as less sources are
rebuilt when things get moved from net/tcp.h.

[NET]: Kill skb->real_dev

2005-08-29T22:32:25+00:00

Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.

It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.

[ATALK] aarp: replace schedule_timeout() with msleep()

2005-06-23T05:11:44+00:00

From: Nishanth Aravamudan 

Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. The current code is not wrong, but it does not account for
early return due to signals, so I think msleep() should be appropriate.
