[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.

[NETROM]: Remove unessecary lock_sock calls in netrom_ioctl()

2006-01-03T22:14:46+00:00

lock_sock is needed only in very few cases, so do it there instead of
around the switch statement.

[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.

[NETROM]: Fix three if-statements in nr_state1_machine()

2005-12-22T02:38:26+00:00

I found these while compiling with extra gcc warnings;
considering the indenting surely they are not intentional?

[AX.25]: Fix packet socket crash

2005-10-05T19:16:04+00:00

Since changeset 98a82febb6340466824c3a453738d4fbd05db81a AX.25 is passing
received IP and ARP packets to the stack through netif_rx() but we don't
set the skb->mac.raw to right value which may result in a crash with
applications that use a packet socket.

[NETROM]: Introduct stuct nr_private

2005-09-12T21:28:03+00:00

NET/ROM's virtual interfaces don't have a proper private data
structure yet.  Create struct nr_private and put the statistics there.

[NETROM]: Implement G8PZT Circuit reset for NET/ROM

2005-09-12T21:27:37+00:00

NET/ROM is lacking a connection reset like TCP's RST flag which at times
may result in a connecting having to slowly timing out instead of just being
reset.  An earlier attempt to reset the connection by sending a
NR_CONNACK | NR_CHOKE_FLAG transport was inacceptable as it did result in
crashes of BPQ systems.  An alternative approach of introducing a new
transport type 7 (NR_RESET) has be implemented several years ago in
Paula Jayne Dowie G8PZT's Xrouter.

Implement NR_RESET for Linux's NET/ROM but like any messing with the state
engine consider this experimental for now and thus control it by a sysctl
(net.netrom.reset) which for the time being defaults to off.

[NETROM]: NET/ROM has no ARP

2005-09-12T21:26:26+00:00

ARP over NET/ROM does not exist so it's obviously not implemented on any
NET/ROM stack, so the NET/ROM interfaces really should default to IFF_NOARP.

[NETROM] NET/ROM has no txqueue

2005-09-12T21:25:57+00:00

NET/ROM uses virtual interfaces so setting a queue length is wrong.
