* [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

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.

* [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.

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

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.
