[NET]: Remove more unneeded typecasts on *malloc()

2006-01-12T00:32:14+00:00

This removes more unneeded casts on the return value for kmalloc(),
sock_kmalloc(), and vmalloc().

[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.

[AF_PACKET]: Convert PACKET_MMAP over to vm_insert_page().

2005-12-07T00:38:35+00:00

So we can properly use __GFP_COMP and avoid the use of
PG_reserved pages.

With extremely helpful review from Hugh Dickins.

[NET]: Fix packet timestamping.

2005-10-03T20:57:23+00:00

I've found the problem in general.  It affects any 64-bit
architecture.  The problem occurs when you change the system time.

Suppose that when you boot your system clock is forward by a day.
This gets recorded down in skb_tv_base.  You then wind the clock back
by a day.  From that point onwards the offset will be negative which
essentially overflows the 32-bit variables they're stored in.

In fact, why don't we just store the real time stamp in those 32-bit
variables? After all, we're not going to overflow for quite a while
yet.

When we do overflow, we'll need a better solution of course.

[AF_PACKET]: Remove bogus checks added to packet_sendmsg().

2005-09-26T22:23:58+00:00

These broke existing apps, and the checks are superfluous
as the values being verified aren't even used.

[AF_PACKET]: Allow for > 8 byte hardware addresses.

2005-09-21T07:11:37+00:00

The convention is that longer addresses will simply extend
the hardeware address byte arrays at the end of sockaddr_ll and
packet_mreq.

In making this change a small information leak was also closed.
The code only initializes the hardware address bytes that are
used, but all of struct sockaddr_ll was copied to userspace.
Now we just copy sockaddr_ll to the last byte of the hardware
address used.

For error checking larger structures than our internal
maximums continue to be allowed but an error is signaled if we can
not fit the hardware address into our internal structure.

[NET]: Use file->private_data to get socket pointer.

2005-09-06T21:42:45+00:00

Avoid touching file->f_dentry on sockets, since file->private_data
directly gives us the socket pointer.
