[IPX]: Fix NULL pointer dereference on ipx unload

2007-02-14T08:40:31+00:00

Fixes a null pointer dereference when unloading the ipx module.

On initialization of the ipx module, registering certain packet
types can fail. When this happens, unloading the module later
dereferences NULL pointers.  This patch fixes that. Please apply.

[IPX]: Annotate and fix IPX checksum

2006-11-24T02:03:34+00:00

Calculation of IPX checksum got buggered about 2.4.0.  The old variant
mangled the packet; that got fixed, but calculation itself got buggered.
Restored the correct logics, fixed a subtle breakage we used to have even
back then: if the sum is 0 mod 0xffff, we want to return 0, not 0xffff.
The latter has special meaning for IPX (cheksum disabled).  Observation
(and obvious fix) nicked from history of FreeBSD ipx_cksum.c...

[IPX]: Another nonlinear receive fix

2006-11-24T01:59:07+00:00

Need to check some more cases in IPX receive.  If the skb is purely
fragments, the IPX header needs to be extracted. The function
pskb_may_pull() may in theory invalidate all the pointers in the skb,
so references to ipx header must be refreshed.

[IPX]: Header length validation needed

2006-11-24T01:57:28+00:00

This patch will linearize and check there is enough data.
It handles the pprop case as well as avoiding a whole audit of
the routing code.

[IPX]: Correct return type of ipx_map_frame_type().

2006-11-24T01:56:20+00:00

Casting BE16 to int and back may or may not work. Correct, to be sure.

[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.
