The reason is that some programs need kernel networking support even
|

If you are upgrading from an older kernel, you
|
2005-04-17 00:20:36 +02:00
|
|
|
should consider updating your networking tools too because changes
|
|
|
|
|
in the kernel and the tools often go hand in hand. The tools are

|

contained in the package net-tools, the location and version number

of which are given in <file:Documentation/Changes>.

net/compat/wext: send different messages to compat tasks
Wireless extensions have the unfortunate problem that events
are multicast netlink messages, and are not independent of
pointer size. Thus, currently 32-bit tasks on 64-bit platforms
cannot properly receive events and fail with all kinds of
strange problems, for instance wpa_supplicant never notices
disassociations, due to the way the 64-bit event looks (to a
32-bit process), the fact that the address is all zeroes is
lost, it thinks instead it is 00:00:00:00:01:00.
The same problem existed with the ioctls, until David Miller
fixed those some time ago in an heroic effort.
A different problem caused by this is that we cannot send the
ASSOCREQIE/ASSOCRESPIE events because sending them causes a
32-bit wpa_supplicant on a 64-bit system to overwrite its
internal information, which is worse than it not getting the
information at all -- so we currently resort to sending a
custom string event that it then parses. This, however, has a
severe size limitation we are frequently hitting with modern
access points; this limitation would can be lifted after this
patch by sending the correct binary, not custom, event.
A similar problem apparently happens for some other netlink
users on x86_64 with 32-bit tasks due to the alignment for
64-bit quantities.
In order to fix these problems, I have implemented a way to
send compat messages to tasks. When sending an event, we send
the non-compat event data together with a compat event data in
skb_shinfo(main_skb)->frag_list. Then, when the event is read
from the socket, the netlink code makes sure to pass out only
the skb that is compatible with the task. This approach was
suggested by David Miller, my original approach required
always sending two skbs but that had various small problems.
To determine whether compat is needed or not, I have used the
MSG_CMSG_COMPAT flag, and adjusted the call path for recv and
recvfrom to include it, even if those calls do not have a cmsg
parameter.
I have not solved one small part of the problem, and I don't
think it is necessary to: if a 32-bit application uses read()
rather than any form of recvmsg() it will still get the wrong
(64-bit) event. However, neither do applications actually do
this, nor would it be a regression.

This option makes it possible to send different netlink messages
|
|
|
|
|
to tasks depending on whether the task is a compat task or not. To
|
|
|
|
|
achieve this, you need to set skb_shinfo(skb)->frag_list to the
|
|
|
|
|
compat skb before sending the skb, the netlink code will sort out
|
|
|
|
|
which message to actually pass to the task.

Newly written code should NEVER need this option but do

compat-independent messages instead!

net, sched: add clsact qdisc
This work adds a generalization of the ingress qdisc as a qdisc holding
only classifiers. The clsact qdisc works on ingress, but also on egress.
In both cases, it's execution happens without taking the qdisc lock, and
the main difference for the egress part compared to prior version of [1]
is that this can be applied with _any_ underlying real egress qdisc (also
classless ones).
Besides solving the use-case of [1], that is, allowing for more programmability
on assigning skb->priority for the mqprio case that is supported by most
popular 10G+ NICs, it also opens up a lot more flexibility for other tc
applications. The main work on classification can already be done at clsact
egress time if the use-case allows and state stored for later retrieval
f.e. again in skb->priority with major/minors (which is checked by most
classful qdiscs before consulting tc_classify()) and/or in other skb fields
like skb->tc_index for some light-weight post-processing to get to the
eventual classid in case of a classful qdisc. Another use case is that
the clsact egress part allows to have a central egress counterpart to
the ingress classifiers, so that classifiers can easily share state (e.g.
in cls_bpf via eBPF maps) for ingress and egress.
Currently, default setups like mq + pfifo_fast would require for this to
use, for example, prio qdisc instead (to get a tc_classify() run) and to
duplicate the egress classifier for each queue. With clsact, it allows
for leaving the setup as is, it can additionally assign skb->priority to
put the skb in one of pfifo_fast's bands and it can share state with maps.
Moreover, we can access the skb's dst entry (f.e. to retrieve tclassid)
w/o the need to perform a skb_dst_force() to hold on to it any longer. In
lwt case, we can also use this facility to setup dst metadata via cls_bpf
(bpf_skb_set_tunnel_key()) without needing a real egress qdisc just for
that (case of IFF_NO_QUEUE devices, for example).
The realization can be done without any changes to the scheduler core
framework. All it takes is that we have two a-priori defined minors/child
classes, where we can mux between ingress and egress classifier list
(dev->ingress_cl_list and dev->egress_cl_list, latter stored close to
dev->_tx to avoid extra cacheline miss for moderate loads). The egress
part is a bit similar modelled to handle_ing() and patched to a noop in
case the functionality is not used. Both handlers are now called
sch_handle_ingress() and sch_handle_egress(), code sharing among the two
doesn't seem practical as there are various minor differences in both
paths, so that making them conditional in a single handler would rather
slow things down.
Full compatibility to ingress qdisc is provided as well. Since both
piggyback on TC_H_CLSACT, only one of them (ingress/clsact) can exist
per netdevice, and thus ingress qdisc specific behaviour can be retained
for user space. This means, either a user does 'tc qdisc add dev foo ingress'
and configures ingress qdisc as usual, or the 'tc qdisc add dev foo clsact'
alternative, where both, ingress and egress classifier can be configured
as in the below example. ingress qdisc supports attaching classifier to any
minor number whereas clsact has two fixed minors for muxing between the
lists, therefore to not break user space setups, they are better done as
two separate qdiscs.
I decided to extend the sch_ingress module with clsact functionality so
that commonly used code can be reused, the module is being aliased with
sch_clsact so that it can be auto-loaded properly. Alternative would have been
to add a flag when initializing ingress to alter its behaviour plus aliasing
to a different name (as it's more than just ingress). However, the first would
end up, based on the flag, choosing the new/old behaviour by calling different
function implementations to handle each anyway, the latter would require to
register ingress qdisc once again under different alias. So, this really begs
to provide a minimal, cleaner approach to have Qdisc_ops and Qdisc_class_ops
by its own that share callbacks used by both.
Example, adding qdisc:
# tc qdisc add dev foo clsact
# tc qdisc show dev foo
qdisc mq 0: root
qdisc pfifo_fast 0: parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :3 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc pfifo_fast 0: parent :4 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc clsact ffff: parent ffff:fff1
Adding filters (deleting, etc works analogous by specifying ingress/egress):
# tc filter add dev foo ingress bpf da obj bar.o sec ingress
# tc filter add dev foo egress bpf da obj bar.o sec egress
# tc filter show dev foo ingress
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bar.o:[ingress] direct-action
# tc filter show dev foo egress
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bar.o:[egress] direct-action
A 'tc filter show dev foo' or 'tc filter show dev foo parent ffff:' will
show an empty list for clsact. Either using the parent names (ingress/egress)
or specifying the full major/minor will then show the related filter lists.
Prior work on a mqprio prequeue() facility [1] was done mainly by John Fastabend.

|
|
|
Netfilter is a framework for filtering and mangling network packets
|
|
|
|
|
that pass through your Linux box.
|
|
|
|
|
|
|
|
|
|
The most common use of packet filtering is to run your Linux box as
|
|
|
|
|
a firewall protecting a local network from the Internet. The type of
|
|
|
|
|
firewall provided by this kernel support is called a "packet
|
|
|
|
|
filter", which means that it can reject individual network packets
|
|
|
|
|
based on type, source, destination etc. The other kind of firewall,
|
|
|
|
|
a "proxy-based" one, is more secure but more intrusive and more
|
|
|
|
|
bothersome to set up; it inspects the network traffic much more
|
|
|
|
|
closely, modifies it and has knowledge about the higher level
|
|
|
|
|
protocols, which a packet filter lacks. Moreover, proxy-based
|
|
|
|
|
firewalls often require changes to the programs running on the local
|
|
|
|
|
clients. Proxy-based firewalls don't need support by the kernel, but
|
|
|
|
|
they are often combined with a packet filter, which only works if
|
|
|
|
|
you say Y here.
|
|
|
|
|
|
|
|
|
|
You should also say Y here if you intend to use your Linux box as
|
|
|
|
|
the gateway to the Internet for a local network of machines without
|
|
|
|
|
globally valid IP addresses. This is called "masquerading": if one
|
|
|
|
|
of the computers on your local network wants to send something to
|
|
|
|
|
the outside, your box can "masquerade" as that computer, i.e. it
|
|
|
|
|
forwards the traffic to the intended outside destination, but
|
|
|
|
|
modifies the packets to make it look like they came from the
|
|
|
|
|
firewall box itself. It works both ways: if the outside host
|
|
|
|
|
replies, the Linux box will silently forward the traffic to the
|
|
|
|
|
correct local computer. This way, the computers on your local net
|
|
|
|
|
are completely invisible to the outside world, even though they can
|
|
|
|
|
reach the outside and can receive replies. It is even possible to
|
|
|
|
|
run globally visible servers from within a masqueraded local network
|
|
|
|
|
using a mechanism called portforwarding. Masquerading is also often
|
|
|
|
|
called NAT (Network Address Translation).
|
|
|
|
|
|
|
|
|
|
Another use of Netfilter is in transparent proxying: if a machine on
|
|
|
|
|
the local network tries to connect to an outside host, your Linux
|
|
|
|
|
box can transparently forward the traffic to a local server,
|
|
|
|
|
typically a caching proxy server.
|
|
|
|
|
|
|
|
|
|
Yet another use of Netfilter is building a bridging firewall. Using
|
|
|
|
|
a bridge with Network packet filtering enabled makes iptables "see"
|
|
|
|
|
the bridged traffic. For filtering on the lower network and Ethernet
|
|
|
|
|
protocols over the bridge, use ebtables (under bridge netfilter
|
|
|
|
|
configuration).
|
|
|
|
|
|
|
|
|
|
Various modules exist for netfilter which replace the previous
|
|
|
|
|
masquerading (ipmasqadm), packet filtering (ipchains), transparent
|
|
|
|
|
proxying, and portforwarding mechanisms. Please see
|
|

<file:Documentation/Changes> under "iptables" for the location of
|
|

net: Distributed Switch Architecture protocol support
Distributed Switch Architecture is a protocol for managing hardware
switch chips. It consists of a set of MII management registers and
commands to configure the switch, and an ethernet header format to
signal which of the ports of the switch a packet was received from
or is intended to be sent to.
The switches that this driver supports are typically embedded in
access points and routers, and a typical setup with a DSA switch
looks something like this:
+-----------+ +-----------+
| | RGMII | |
| +-------+ +------ 1000baseT MDI ("WAN")
| | | 6-port +------ 1000baseT MDI ("LAN1")
| CPU | | ethernet +------ 1000baseT MDI ("LAN2")
| |MIImgmt| switch +------ 1000baseT MDI ("LAN3")
| +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4")
| | | |
+-----------+ +-----------+
The switch driver presents each port on the switch as a separate
network interface to Linux, polls the switch to maintain software
link state of those ports, forwards MII management interface
accesses to those network interfaces (e.g. as done by ethtool) to
the switch, and exposes the switch's hardware statistics counters
via the appropriate Linux kernel interfaces.
This initial patch supports the MII management interface register
layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and
supports the "Ethertype DSA" packet tagging format.
(There is no officially registered ethertype for the Ethertype DSA
packet format, so we just grab a random one. The ethertype to use
is programmed into the switch, and the switch driver uses the value
of ETH_P_EDSA for this, so this define can be changed at any time in
the future if the one we chose is allocated to another protocol or
if Ethertype DSA gets its own officially registered ethertype, and
everything will continue to work.)

VSOCK: Introduce VM Sockets
VM Sockets allows communication between virtual machines and the hypervisor.
User level applications both in a virtual machine and on the host can use the
VM Sockets API, which facilitates fast and efficient communication between
guest virtual machines and their host. A socket address family, designed to be
compatible with UDP and TCP at the interface level, is provided.
Today, VM Sockets is used by various VMware Tools components inside the guest
for zero-config, network-less access to VMware host services. In addition to
this, VMware's users are using VM Sockets for various applications, where
network access of the virtual machine is restricted or non-existent. Examples
of this are VMs communicating with device proxies for proprietary hardware
running as host applications and automated testing of applications running
within virtual machines.
The VMware VM Sockets are similar to other socket types, like Berkeley UNIX
socket interface. The VM Sockets module supports both connection-oriented
stream sockets like TCP, and connectionless datagram sockets like UDP. The VM
Sockets protocol family is defined as "AF_VSOCK" and the socket operations
split for SOCK_DGRAM and SOCK_STREAM.
For additional information about the use of VM Sockets, please refer to the
VM Sockets Programming Guide available at:

This feature provides an infrastructure to support light weight
|
|
|
|
|
tunnels like mpls. There is no netdevice associated with a light
|
|
|
|
|
weight tunnel endpoint. Tunnel encapsulation parameters are stored
|
|
|
|
|
with light weight tunnel state associated with fib routes.
