Nobody is going to look at your code, let alone help review it
for inclusion, if you just say "go look at this stuff on this
sourceforge web site."
You have to post the kernel patches here, one by one.

Can you do me a huge favor?
In the future make the dates more sensible in your patch postings.
With how you did this, your patches are scattered all over the place
in patchwork because it orders things by date, have a look:

Thanks for the hint. I used git format-patch and it creates Date
headers based on git commit time. I'll probably just filter them
or git rebase before sending patches from now on.

* [PATCH] text ematch: check for NULL pointer before destroying textsearch config
From: Thomas Graf @ 2010-10-31 8:06 UTC (permalink / raw)
To: davem; +Cc: netdev
While validating the configuration em_ops is already set, thus the
individual destroy functions are called, but the ematch data has
not been allocated and associated with the ematch yet.

Aren't the generic length limiting changes (8acfe46 and 253eacc) also
supposed to cover the overflow issues with TIPC? Or are those still
unfixed?

* tc action mirred packet lost
From: Nieścierowicz Adam @ 2010-10-31 12:44 UTC (permalink / raw)
To: netdev
Hello,
recently there was a need to create 3-4 copies of the data sent to the
router, I decided to use the tc action mirred.
Ingress traficn on eth1 copies to eth1 eth2, eth3, eth4, eth5 using:
---
tc qdisc add dev eth1 ingress
tc filter add dev eth1 parent ffff: protocol ip prio 10 u32 match ip
src
0/0 flowid 1:1 action mirred egress mirror dev eth2 pipe action mirred
egress mirror dev eth3 pipe action mirred egress mirror dev eth4 pipe
action mirred egress mirror dev eth5
--
Unfortunately the number of packets seen on eth1 qdisc is different
than the eth [2-5]

Am I doing something wrong, or what is a purpose of packet loss.

Yes, the TIPC issues should be cured by those generic networking changes.

OK, no problem. I tried it and it solves the problem. Here is an
official patch submission.
David, for your convenience, I cooked a patch serie for the 2 patches
against af_unix unix_dgram_poll().
The third patch (af_unix: unix_write_space() use keyed wakeups)) can be
applied as is.
Thanks !
[PATCH 1/2] af_unix: fix unix_dgram_poll() behavior for EPOLLOUT event
Alban Crequy reported a problem with connected dgram af_unix sockets and
provided a test program. epoll() would miss to send an EPOLLOUT event
when a thread unqueues a packet from the other peer, making its receive
queue not full.
This is because unix_dgram_poll() fails to call sock_poll_wait(file,
&unix_sk(other)->peer_wait, wait);
if the socket is not writeable at the time epoll_ctl(ADD) is called.
We must call sock_poll_wait(), regardless of 'writable' status, so that
epoll can be notified later of states changes.
Misc: avoids testing twice (sk->sk_shutdown & RCV_SHUTDOWN)

* [PATCH 2/2] af_unix: optimize unix_dgram_poll()
From: Eric Dumazet @ 2010-10-31 15:38 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Davide Libenzi, Alban Crequy
unix_dgram_poll() is pretty expensive to check POLLOUT status, because
it has to lock the socket to get its peer, take a reference on the peer
to check its receive queue status, and queue another poll_wait on
peer_wait. This all can be avoided if the process calling
unix_dgram_poll() is not interested in POLLOUT status. It makes
unix_dgram_recvmsg() faster by not queueing irrelevant pollers in
peer_wait.
On a test program provided by Alan Crequy :
Before:
real 0m0.211s
user 0m0.000s
sys 0m0.208s
After:
real 0m0.044s
user 0m0.000s
sys 0m0.040s

Can this patch be modified to move the netif_stop_queue()
after register_netdev() ?
It seems the __QUEUE_STATE_XOFF is not set after the register_netdev.
The tx_queue was kcalloc() ed without touching state flags.

At the veyr moment that register_netdev() is called, the
->open() method of your driver can be invoked and the
queue state changed.
So no, you can't put it after the register call.
There is zero reason to touch the queue state in your
probe routine, the state of the queue before ->open()
is "don't care".
Eric's patch is going to be applied, it is correct.

Real question is : why this netif_stop_queue() was needed at the first
place ?
We believe (David and others), that using before ndo_open() is useless
or a sign of design error.

If your driver doesnt work after my change, then another patch is
needed, but not using netif_stop_queue() right after register_netdev()

* [PATCH 1/3] net: ax25: fix information leak to userland
From: Vasiliy Kulikov @ 2010-10-31 17:10 UTC (permalink / raw)
To: kernel-janitors
Cc: Joerg Reuter, Ralf Baechle, David S. Miller, linux-hams, netdev,
linux-kernel
Sometimes ax25_getname() doesn't initialize all members of fsa_digipeater
field of fsa struct. This structure is then copied to userland. It leads to
leaking of contents of kernel stack memory. We have to initialize them to zero.
