tipc: Fix bug in scope checking for multicast messages · 08d2cf0f

Allan Stephens authored Jul 14, 2008

This patch ensures that TIPC's multicast message name lookup
algorithm does individualized scope checking for each published
name it examines.  Previously, scope checking was only done for
the first name in a name table publication list, which could
result in incoming multicast messages being delivered to ports
publishing names with "node" scope, or not being delivered to
ports publishing names with "cluster" or "zone" scope.

tipc: Eliminate improper use of TIPC_OK error code · 0e35fd5e

Allan Stephens authored Jul 14, 2008

This patch corrects many places where TIPC routines indicated
successful completion by returning TIPC_OK instead of 0.
(The TIPC_OK symbol has the value 0, but it should only be used
in contexts that deal with the error code field of a TIPC
message header.)

tipc: Fix race condition that could cause accept() to fail · 2da59918

Allan Stephens authored Jul 14, 2008

This patch ensurs that accept() returns successfully even when
the newly created socket is immediately disconnected by its peer.
Previously, accept() would fail if it was unable to pass back
the optional address info for the socket's peer before the
socket became disconnected; TIPC now allows accept() to gather
peer address information after disconnection.  As a bonus, the
revised code accesses the socket's port more efficiently, without
the overhead incurred by a reference table lookup.

tipc: Remove unneeded parameter to tipc_createport_raw() · 0ea52241

Allan Stephens authored Jul 14, 2008

This patch eliminates an unneeded parameter when creating a low-level
TIPC port object. Instead of returning both the pointer to the port
structure and the port's reference ID, it now returns only the pointer
since the port structure contains the reference ID as one of its fields.

bnx2: Support secondary MAC addresses. · 5fcaed01

Benjamin Li authored Jul 14, 2008

Add support for configuring secondary unicast addresses.  There
are 4 additional perfect match filters which can be used for
secondary unicast address support.

  *  Modified bnx2_set_mac_addr() to be more generic in handling
     the setting of the perfect match filters
  *  Changed bnx2_set_rx_mode() to handle the unicast dev_addr_list

netlabel: return msg overflow error from netlbl_cipsov4_list faster · 83aa2e96

Denis V. Lunev authored Jul 14, 2008

Currently, we are trying to place the information from the kernel to
1, 2, 3 and 4 pages sequentially. These pages are allocated via slab.
Though, from the slab point of view steps 3 and 4 are equivalent on
most architectures. So, lets skip 3 pages attempt.

By the way, should we switch from .doit to .dumpit interface here?
The amount of data seems quite big for me.

tun: Fix/rewrite packet filtering logic · f271b2cc

Max Krasnyansky authored Jul 14, 2008

Please see the following thread to get some context on this
	http://marc.info/?l=linux-netdev&m=121564433018903&w=2

Basically the issue is that current multi-cast filtering stuff in
the TUN/TAP driver is seriously broken.
Original patch went in without proper review and ACK. It was broken and
confusing to start with and subsequent patches broke it completely.
To give you an idea of what's broken here are some of the issues:

- Very confusing comments throughout the code that imply that the
character device is a network interface in its own right, and that packets
are passed between the two nics. Which is completely wrong.

- Wrong set of ioctls is used for setting up filters. They look like
shortcuts for manipulating state of the tun/tap network interface but
in reality manipulate the state of the TX filter.

- ioctls that were originally used for setting address of the the TX filter
got "fixed" and now set the address of the network interface itself. Which
made filter totaly useless.

- Filtering is done too late. Instead of filtering early on, to avoid
unnecessary wakeups, filtering is done in the read() call.

The list goes on and on :)

So the patch cleans all that up. It introduces simple and clean interface for
setting up TX filters (TUNSETTXFILTER + tun_filter spec) and does filtering
before enqueuing the packets.

TX filtering is useful in the scenarios where TAP is part of a bridge, in
which case it gets all broadcast, multicast and potentially other packets when
the bridge is learning. So for example Ethernet tunnelling app may want to
setup TX filters to avoid tunnelling multicast traffic. QEMU and other
hypervisors can push RX filtering that is currently done in the guest into the
host context therefore saving wakeups and unnecessary data transfer.
