* tap0 device stopped working in 2.6.36 (ok in 2.6.35)
From: Jim @ 2010-10-23 12:55 UTC (permalink / raw)
To: netdev; +Cc: nolan
My tap0 device stopped working with 2.6.36, seems it couldn't
send any packets anymore (receiving was still fine).
After some checking noticed that apparently link isn't ready:
modprobe tun
tunctl -b
ifconfig tap0 192.168.20.1 up
Gives:
[ 26.411932] ADDRCONF(NETDEV_UP): tap0: link is not ready
Bisected it all the way to this commit:

tun: keep link (carrier) state up to date
Currently, only ethtool can get accurate link state of a tap device.
With this patch, IFF_RUNNING and IF_OPER_UP/DOWN are kept up to date as
well.

Apply-ing this patch on top of vanilla 2.6.36 makes the tap device
working again for me (strangely in the function __tun_detach):

There are also new drivers for speakup, intel_sst and yurex that introduce
additional file_operations in next, the patch below is what I had planned
to submit once everything is in. I also expect the occasional driver that
did not see linux-next, so I'll rerun my scripts after -rc1 to see what
we got.
As Christoph mentioned, we probably shouldn't make new drivers use
noop_llssek if possible nor add an explicit no_llseek and we can just
leave those with the implicit no_llseek.
Once open question is what pread/pwrite should do if there is no
llseek function. Right now they are both possible, but it would also
be logical to turn this into an implicit nonseekable_open, which forbids
pread/pwrite as well.

* [PATCH] Fix PC-300 driver for 64-bit cleanliness and recent HDLC/tty_driver
From: Andrea Shepard @ 2010-10-23 9:10 UTC (permalink / raw)
To: khc; +Cc: netdev, linux-kernel
This is an updated and fixed version of the Cyclades PC-300 WAN interface
driver which is presently marked 'Broken' in 2.6.36. The version in the kernel
is based on Cyclades' version 3.23, and has many portability bugs as well as being
incompatible with recent tty_driver and HDLC changes (for values of recent < about
three years...). Cyclades does not seem to be maintaining this driver any longer,
as the most recent version was released in 2005.
This patch merges in Cyclades' most recent version, 4.1.0, and updates it to work
with current kernel interfaces for tty_driver and HDLC, and fixes problems with
portability and 64-bit cleanliness. It also contains some style fixups.
Due to some ioctls using non-portable interfaces (specifically, passing kernel
pointers and unsigned longs out to userland, which fails in the case of a 32-bit
process on a 64-bit kernel), some of the structures involved have been redesigned.
Thus, a new version of the userland package, pc300utils, is required. This me
obtained at:
http://charon.persephoneslair.org/~andrea/software/pc300utils/
This patch is tested and known to work on a sparc64 kernel with a single-port
Cyclades PC-300 TE1 board using a full T1 circuit, with both 32-bit and 64-bit
userland utilities.
I am not subscribed to this list, so please CC me on replies.

If different containers can have different memory limit
we should restrict their memory with per-ns limits
and variables, i.e. DoS logic per-ns.

Main points:
- May be we have to use global table for connections and to
filter by cp->net
- We have to use ip_vs_proto_data_get in many places where
pp = ip_vs_proto_get(protocol) was used. Then when pp
is needed we can use pd->pp->XXX
- tcp_timeout_change should work with the new struct ip_vs_proto_data
so that tcp_state_table will go to pd->state_table
and set_tcp_state will get pd instead of pp
- ipvs_skbnet must be used only for traffic after the
check for !skb_dst(skb)
Other notes:
rfc v2 01/10:
set_state_timeout: infrastructure is there but never added
to ipvsadm. If we keep it, it should be per-ns

There is no obligation RCU shall be used in a slow path algorithm.
This slow path uses regular locking to prevent another process to change
the things while we read them, thats it.
Patrick made a change in the past so that RTNL is locked on dump
operations, so no dump_rules() is in fact protected by RTNL, it doesnt
need to take care of 'RCU'.

Incidently, I believe that this problem will only become more acute
and complex if support for 802.1ad (Provider Bridges, aka Q-in-Q),
802.1ah (Provider Backbone Bridges, aka MAC-in-MAC) or other standards
which further extend the maximum frame size.
Dave, you were mentioning to me the other day that the kernel
already supports some notion of Q-in-Q (though its not 802.1ad).
Does the current implementation allow for frames > 1504 bytes?
Is that a complication to the change proposed here?

Hi Hans,
this is a re-base of your patch-set against the current nf-next-2.6 tree,
which includes all the changes currently queued for 2.6.37-rc1 and nothing
else.
I also removed the BUG_ON() statements and incorported various
suggestions that were made in response to your original post.
It is compile tested only (partly because I am in an areoplane).
I have not re-split the patches into logical units.
Having worked with these patches a bit, I really think
that split needs to occur.
For the benefit of others, your original cover email is below,
updated as appropriate.
-----
This patch series adds network name space (netns) support to the LVS.
REVISION
This is version 2
OVERVIEW
The patch doesn't remove or add any functionality except for netns.
For users that don't use network name space (netns) this patch is
completely transparent.
No it's possible to run LVS in a Linux container (see lxc-tools)
i.e. a light weight virtualization. For example it's possible to run
one or several lvs on a real server in their own network name spaces.
>From the LVS point of view it looks like it runs on it's own machine.
IMPLEMENTATION
Basic requirements for netns awareness
- Global variables has to be moved to dyn. allocated memory.
Most global variables now resides in a struct ipvs { } in netns/ip_vs.h.
What is moved and what is not ?
Some cache aligned locks are still in global, module init params and some debug_level.
Algorithm files they are untouched.
QUESTIONS
Drop rate in ip_vs_ctl per netns or grand total ?
Should more lock variables be moved (or less) ?
Include files,
A new file added include/net/netns/ip_vs.h containg all netns specific data.
include/net/net_namespce.h, pointer to "struct ipvs" added.
include/net/ip_vs.h a new struct added, and many prototypes changed.
* ip_vs_core.c
All netns init origins from this file - ip_vs_init()
* ip_vs_conn.c
Lock array for conn table is kept due to performance,
(or am I wrong here ?).
"static struct ip_vs_aligned_lock
__ip_vs_conntbl_lock_array[CT_LOCKARRAY_SIZE] __cacheline_aligned;"
* ip_vs_ctl.c
drop_ rate is still global
TESTING
This patch have been running for a month now with three LVS/machine
one in root name-space and two in other name-space.
Both IPv4 & IPv6 have been tested in all three modes DR/TUN and NAT
Only a limited set of algos have been used (read rr).
Backup have been there all the time and a switch has been performed a couple of times.
Not tested yet:
Drop level, DOS, schedulers, performance ....
Netns exit after usage of LVS (due to a bug in netdev/ipip somewhere tunl0 and

* [rfc v2 03/10] ipvs network name space aware: conn
From: Simon Horman @ 2010-10-22 20:09 UTC (permalink / raw)
To: lvs-devel, netdev, netfilter-devel
Cc: Hans Schillstrom, Julian Anastasov, Daniel Lezcano, Wensong Zhang

[-- Attachment #1: ipvs-netns-3.patch --]
[-- Type: text/plain, Size: 19853 bytes --]
This patch just contains ip_vs_conn.c
and does the normal
- moving to vars to struct ipvs
- adding per netns init and exit
proc_fs required some extra work with adding/chaning private data to get the net ptr.

* [rfc v2 09/10] ipvs network name space aware: proto
From: Simon Horman @ 2010-10-22 20:09 UTC (permalink / raw)
To: lvs-devel, netdev, netfilter-devel
Cc: Hans Schillstrom, Julian Anastasov, Daniel Lezcano, Wensong Zhang
In-Reply-To: <20101022200934.822223308@joe.akashicho.tokyo.vergenet.net>
[-- Attachment #1: ipvs-netns-8.patch --]
[-- Type: text/plain, Size: 30032 bytes --]
This patch contains all proto files
All timeouts are moved to ipvs struct.
Global "timeout tables" are used as default values only.

* Re: kernel panic in fib_rules_lookup [2.6.27.7 vendor-patched]

> Could you provide a disassembly of function fib_rules_lookup ?
Try looking in http://68.100.141.95:3000/linux-crash/. There should be
the source file I am using (not current release if you recall), the .o,
the disassembly, and a -S compile that makes deducing the line numbers a
little easier.
I have tried adding a recursive spinlock as a quick fix without much
success. It looks like the code in net/core/fib_rules.c results in some
rather complex code paths through the kernel involving softirq handlers.
I get lockups though I took steps to make sure local interrupts were
off and preemption disabled when taking the spinlock.
I do not know the RCU API or the network code at all but some of the
code in fib_rules.c does not look right prima facie. For example,
dump_rules does not seem to bother about RCU when traversing rules_list.
Its caller, fib_nl_dumprule does, but only for one of two calls. The
fib_nl_newrule and fib_nl_delrule functions traverse rules_list without
any obvious RCU precautions.

* [rfc v2 10/10] ipvs network name space aware: sync and xmit
From: Simon Horman @ 2010-10-22 20:09 UTC (permalink / raw)
To: lvs-devel, netdev, netfilter-devel
Cc: Hans Schillstrom, Julian Anastasov, Daniel Lezcano, Wensong Zhang
In-Reply-To: <20101022200934.822223308@joe.akashicho.tokyo.vergenet.net>
[-- Attachment #1: ipvs-netns-9.patch --]
[-- Type: text/plain, Size: 24661 bytes --]
This patch contains ip_vs_sync.c and ip_vs_xmit.c
There is one sync daemon per netns, and a number is prepended to its name.
(a kind of incarnation counter)
Part of the netns migration in ip_vs_xmit.c was done in the IPv6 tunnel patch,
so make sure that "[patch v4] ipvs: IPv6 tunnel mode" is applied
Signed-off-by:Hans Schillstrom <hans.schillstrom@ericsson.com>

* Add ipvs_skbnet() as suggested by Julian Anastasov

This is patch 2/9 previous was just a copy of patch 1/9
This patch just contains ip_vs_app.c
There is nothing special whith this file,
just the normal,
- moving to vars to struct ipvs
- adding per netns init and exit
