A bit lower in the array we access 'parents[depth]'.
So the correct check should be (depth >= CTL_MAXNAME) => error.

Lots of little fixes in here, as is usually the case at this point.
The qeth fixes and the XEN netfront buggy guest handling are the
largest changes, with the ipv4/ipv6 multicast compat ioctl handling
bits next in terms of size.
1) Missing ref grab in netfilter conntrack netlink, from Pablo Neira Ayuso.
2) IPV6 boundary checks busted in xt_iprange module, from Thomas Jacob.
3) Wrong indexes used in loop in batman-adv module, leading to crash, fix
from Linus Lüssing.
4) rtlwifi refactoring caused regressions in firmware upload, fix from
Chaoming Li.
5) Fix error handling in ath5k_hw_dma_stop, from Bob Copeland.
6) Frame endianness fixes in ath5k, also from Bob Copeland.
7) Fix crashes due to ath9k tasklet shutdown races, from Stanislaw Gruszka.
8) Fix build warnings in econet, from Eric Dumazet.
9) Handle buggy guests setting of NETRX_csum_* in XEN netfront driver, from
Ian Campbell.
10) Fix DMA-API debugging message spew in dl2k driver due to double
unmaps. Fix from Stanislaw Gruszka.
11) In rtnetlink, validate_linkmsg() uses wrong afinfo pointer. Fix
from Kurt Van Dijck.
12) __alloc_skb() needs kmemcheck annotations to avoid false positives,
from Eric Dumazet.
13) Remove some complications wrt. ipv6 inetpeer binding. All reports
about triggered warnings et al. should be gone now.
14) napi_reuse_skb() must reset skb->dev and skb->iif, from Herbert Xu
and Andy Gospodarek.
15) CAIF protocol headers need userspace export. From Sjur Braendeland.
16) Fix oops on adding network namespace, fix from Eric W. Biederman.
17) ipv4 and ipv6 multicast ioctls need compat handling. Based upon
some initial work by Eric W. Biederman and some audits by Arnd
Bergmann.
18) batman-adv module unhashes wrong object on failures, fix from
Sven Eckelmann.
19) batman-adv forgets to free memory in free_info(), also from Sven.
20) batman-adv list traversal in send_vis_packets() drops lock inside
it's loop, so we have to iterate over the head to be thread safe.
Also from Sven Eckelmann.
21) bnx2x driver fixes from Yaniv Rosner and Eilon Greenstein.
22) wl12xx wireless has use-after-free error, fix from Mathias Krause.
23) Fix OOPS regression with IPSEC, ipv4/ipv6 blackhole dst ops need
to implement a "default_mtu" method. Fix from Roland Dreier.
24) CAN softing driver needs to depend upon IOMEM.
25) get_rps_cpu() erroneously elides flow processing when RPS map has
length of one. Fix from Tom Herbert.
26) ipv6 unregisters sysctl tables in wrong order, resulting in
WARNING in unregister_sysctl_table(). Fix from Eric W. Biederman.
27) enc28j60 driver uses "sizeof(pointer)" when it means "sizeof(array)",
fix from Stefan Weil.
28) vhost spews bogus RCU warnings, fix from Micahel S. Tsirkin.
29) arpt_mangle.c's checkentry() was changed to return int, but it
still erroneously returns "false" and "true". Fix from Pable
Neira Ayuso.
30) Fix netfilter conntrack event filtering, also from Pablo.
31) SKB leak in ath_paprd_send_frame(), fix from Mohammed Shafi Shajakhan.
32) Mixed up boolean operators in vxge driver result in condition
always true, fix from Stefan Weil.
33) Remove use of undefined operation in depca driver, from Alan Cox.
34) ISDN icn driver strncpy() usage fix, from Stefan Weil.
35) be2net driver erroneously mucks with tx queue status during link
up/down, resulting in crashes. Fix from Ajit Khaparde.
36) be2net illegally calls netif_stop_queue() before register_netdevice()
happens, also from Ajit.
37) s390 qeth fixes from Ursula Braun, Frank Blaschka, and Stefan Weil.
38) Fix races between interface up/down and get_stats in NIU driver.
39) Like nlmsg_cancel(), genlmsg_cancel() must explicitly handle NULL
second argument (before we subtract from it and it no longer
looks like "NULL"). Analysis and fix from Julia Lawall.
40) R8169 bug fixes via Francois Romieu:
a) 8168c needs RxFIFO overflow workaround too, from Ivan Vecera.
b) Refine RxFIFO overflow logic to reset less, from Francois.
c) Interrupt handler needs to be more careful in RxFIFO overflow
cases, also from Francois.
41) Bridging code inserts FDB entries to the hash table before they
are fully initialized. Since FDB lookup uses RCU this is a serious
issue, from Pavel Emelyanov.
42) Some CAN drivers create world-writable sysfs files, oops. Fix from
Vasiliy Kulikov.
Please pull, thanks a lot!

* [PATCH 1/6] sysctl: faster reimplementation of sysctl_check_table
From: Lucian Adrian Grijincu @ 2011-02-04 20:31 UTC (permalink / raw)
To: linux-kernel, netdev, Eric W. Biederman, Eric Dumazet,
David S. Miller, Oct
Cc: Lucian Adrian Grijincu
In-Reply-To: <m1oc6rio5u.fsf@fess.ebiederm.org>
Determining the parent of a node at depth d
- previous implementation: O(d)
- current implementation: O(1)
Printing the path to a node at depth d
- previous implementation: O(d^2)
- current implementation: O(d)
This comes to a cost: we use an array ('parents') holding as many
pointers as there can be sysctl levels (currently CTL_MAXNAME=10).
The 'parents' array of pointers holds the same values as the
ctl_table->parents field because the function that updates ->parents
(sysctl_set_parent) is called with either NULL (for root nodes) or
with sysctl_set_parent(table, table->child).

?? DupACK by defination does not slide the left edge?!? :-) ...It
certainly makes a difference whether the ACK is cumulative or not.
Anyway, I tcpdumped it now and confirmed that advertized window is not
advanced if OOO packet arrives.

I also think along the lines that the advertized window autotuning code
is just unnecessarily preventive (besides the IW change, also Quickstart
couldn't be used that efficiently because of it).

This seems reasonable but we need to be careful in how we merge this so
the individual trees are correct.

Are you really sure?
I ran this code on a machine with and without these patches. It seems
to work fine.
It reads the value from /proc/sys/net/ipv4/conf/default/tag and writes 42 back.
I'm not sure what I have to do to pass the name of a device (e.g.
"eth0") instead of "default" but at least "default" and "all" work and
have valid dentries.

args.name = name;

oldtag = -1;

args.oldlenp = &oldtaglen;
newtag = 42;

* [PATCH] bridge: Don't put partly initialized fdb into hash
From: Pavel Emelyanov @ 2011-02-04 15:58 UTC (permalink / raw)
To: Stephen Hemminger, David Miller; +Cc: bridge, Linux Netdev List
The fdb_create() puts a new fdb into hash with only addr set. This is
not good, since there are callers, that search the hash w/o the lock
and access all the other its fields.
Applies to current netdev tree.

* [PATCH 00/20] world-writable files in sysfs and debugfs
From: Vasiliy Kulikov @ 2011-02-04 14:00 UTC (permalink / raw)

The search was made with trivial shell commands:
find | xargs grep S_IWUGO
find | xargs grep S_IWOTH
I didn't precisely investigate how exactly one may damage the
system/hardware because of issues number, maybe the harm is very limited
in case of some of these drivers.
One suspicious file is ./staging/speakup/speakup.h, but it explitly calls
macros as world-writable. I didn't check what speakup's world-writable
files provide because it requires some knowledge about the hardware.

I don't think we should merge this with the MARK target, I don't
want to bloat the simple mark structure with all the parameters
needed for this module.

Actually it should be pretty simple since nf_ct_get() doesn't have any
module dependencies. If it succeeds, use the addresses from the tuples,
otherwise fall back to getting them directly from the packet.

We only use our debugfs entries as root so it shouldn't matter much, this
is way better, thanks for fixing.
