Looks like unbalanced locking.

DECNET: Handle a failure in neigh_parms_alloc (take 2)

2007-02-14T08:02:36+00:00

While enhancing the neighbour code to handle multiple network
namespaces I noticed that decnet is assuming neigh_parms_alloc
will allways succeed, which is clearly wrong.  So handle the
failure.

[DECNET]: Only use local routers

2006-01-03T22:24:02+00:00

The attached patch makes DECnet routing only use routers from the same
area - rather than the highest rated router seen.

In theory there should not be an out-of-area router on a local network
but some networks are bridged rather than properly routed. VMS seems
to behave similarly: if I bring up a VMS node with no router then it
can't see anything else on the global network.

[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.

[SOCK]: Introduce sk_receive_skb

2006-01-03T21:11:19+00:00

Its common enough to to justify that, TCP still can't use it as it has the
prequeueing stuff, still to be made generic in the not so distant future :-)

[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.

[DECNET]: add memory buffer settings

2005-12-05T21:42:06+00:00

The patch (originally from Steve) simply adds memory buffer settings to 
DECnet similar to those in TCP.

[DECNET]: fix SIGPIPE

2005-11-11T20:04:28+00:00

Currently recvmsg generates SIGPIPE whereas sendmsg does not; for the
other stacks it seems to be the other way round!

It also fixes the bug where reading from a socket whose peer has shutdown
returned -EINVAL rather than 0.
