This is not indented correctly.

On some architectures, structures have a minimum alignment of 4, so
there are 2 bytes of padding before sax25_call and 1 byte within it.
nr_getname() copies complete ax25_address structures, but nr_listen()
does not initialise the 1 byte of padding in user_addr:
memset(&nr_sk(sk)->user_addr, 0, AX25_ADDR_LEN);
So I think you should address that too. It appears that other
ax25_address structures are originally copied from userland and
therefore don't leak information, but I'm not sure.

XID identifies the chipset. If the chipset stops responding - all 1 bits -
the device can not be identified.

Can you try both a 3.5 kernel with the 3.6 r8169 driver and a 3.6 kernel
with the 3.5 r8169 driver ?

So ntpd claims to "Listen normally on 4 lo ::1 UDP 123" but lsof doesnt
display a socket bound to ::1 port 123
So I would say there is a ntpd bug.
You could try to strace ntpd from the very beginning of its life, so
that we check what it does exactly.
service ntp stop
strace -o /tmp/STRACE /usr/bin/ntpd -g -u ntp:ntp

Hmm, your ntpd doesnt listen normally to ::1 UDP 123

I already got these files, thank you
I asked a strace of the ntpd daemon, since we now know frames are
delivered to the application. I want to check what ntpd does of these
frames, since apparently it gives no answer.

ip -6 addr gives:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000

And the output of "strace ntpq -p" is attached in file "ntpq-p".
I also did a tcpdump earlier this day as told in the bugtracker. Find
the parts containing "ntpd" attached in file "tcpdump".

OK so IPv6 UDP frames are delivered to ntpd
could you strace it while doing one "ntpq -p"
strace -p 368

Hmm
pidof ntpd
should give you the pid of ntpd process : 368
So try
lsof -p 368 # instead of lsof -p `pidof ntpd`

* [PATCH] checkpatch: Improve network block comment style checking
From: Joe Perches @ 2012-10-14 19:35 UTC (permalink / raw)
To: Larry Finger, Andrew Morton; +Cc: Andy Whitcroft, LKML, netdev
In-Reply-To: <50787432.8030805@lwfinger.net>
Some comment styles in net and drivers/net are flagged inappropriately.
Avoid proclaiming inline comments like:
int a = b; /* some comment */
and block comments like:
/*********************
* some comment
********************/
are defective.
Tested with
$ cat drivers/net/t.c
/* foo */
/*
* foo
*/
/* foo
*/
/* foo
* bar */
/****************************
* some long block comment
***************************/
struct foo {
int bar; /* another test */
};

as I discussed with Jesse on IRC, there is another possible deadlock
lurking in the e1000 code.
static void e1000_reinit_safe(struct e1000_adapter *adapter)
{
while (test_and_set_bit(__E1000_RESETTING, &adapter->flags))
msleep(1);
mutex_lock(&adapter->mutex);
e1000_down(adapter);
e1000_down() waits on the various work tasks to shut down, but those
work functions might be blocked on the adapter mutex.
I have no idea how I managed to trigger that one, but it's real. The
task dump I got out of the machine shows stuff waiting on each other
forever.
I can't give you a receipe to reprodruce. Looking at the code this is
not very surprising. It takes quite some coincidence of having
e1000_reinit_safe() being invoked and the delayed work timer bringing
the work on right after e1000_reinit_safe() took the adapter mutex.
Thanks,
tglx

* [PATCH] netrom: fix info leak via getsockname()
From: Clément Lecigne @ 2012-10-14 18:23 UTC (permalink / raw)
To: netdev
[-- Attachment #1: Type: text/plain, Size: 951 bytes --]
The following patch fixes a 3 bytes info leak via getsockname() on
AF_NETROM socket.
Details:
typedef struct {
char ax25_call[7]; /* 6 call + SSID (shifted ascii!) */
} ax25_address;
struct sockaddr_ax25 {
__kernel_sa_family_t sax25_family;
ax25_address sax25_call;
int sax25_ndigis;
/* Digipeater ax25_address sets follow */
};
After compilation, gcc will add 3 padding bytes after sax25_call to
align sax25_ndigis and nr_getname does not clear these padding bytes
before returning to userland, poc attached.

* regression when connecting to ipv6 localhost
From: Jan Hinnerk Stosch @ 2012-10-14 15:38 UTC (permalink / raw)
To: netdev
Hi,
I detected a small regression since linux 3.6.0:
When I run "ntpq -p" to query the status of my ntp-daemon I receive a
timeout (localhost.localdomain: timed out, nothing received
***Request timed out). Strace shows that connecting to the ipv6
loopback interface times out. If I explicitly use ipv4 (ntpq -4 -p)
everything works as intended. Downgrading to linux 3.5.6 solves that
issue.
I reported a bug both to my distribution
(https://bugs.archlinux.org/task/31775) and to the kernel bugtracker
(https://bugzilla.kernel.org/show_bug.cgi?id=48741) not knowing
exactly which component caused the regression, so I was told to ask
this here. At the kernel-report you find an strace and tcpdump output.
If you need any further information just tell me, but be patient as me
kernel knowledge tends to zero.
Thanks in advance, Jan Hinnerk
