* [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 */
};

ntp.conf is (without comments):
server fritz.box iburst
restrict default noquery nopeer nomodify
restrict 127.0.0.1
restrict ::1
driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp.log
"lsof -p `pidof ntpd`" gives nothing
and "ntpq -p ::1" results in the same timeout error "::1: timed out,
nothing received
***Request timed out".

No, of course it is running:

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

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

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
inet6 fe80::922b:34ff:fe33:c292/64 scope link
valid_lft forever preferred_lft forever
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".

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.

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

Ok, here is the strace output. I wonder whether this is enough as it
exits very early - ntp still running though.

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.

* [PATCHv5 0/4] modem_shm: U8500 SHaRed Memory driver(SHRM)
From: Arun Murthy @ 2012-10-15 5:28 UTC (permalink / raw)
To: linux-kernel, netdev, linux-doc, gregkh, alan; +Cc: Arun Murthy
In u8500 platform the communication between the APE(Application Processor) and
the modem subsystem(CMT) is by means of a shared DDR. The series of patches
include a protocol called ShaRed Memory(SHRM) protocol for communicating
between the APE and the CMT.
Interrupt generation registers in CMT and PRCMU on APE side are used to support
the shrm protocol.
v2 - Included netdev mailing list
v3 - Implemented comments from Alan Cox and Greg KH
v4 - Re-worked on the ModemAccessFramework(MAF) part
v5 - Added kernel doc for exported functions in MAF.

In-Reply-To: <1350278920-25510-1-git-send-email-arun.murthy@stericsson.com>
Adds Modem Access Framework, which allows for registering platform specific
modem access mechanisms. The framework also exposes APIs for client drivers
for getting and releasing access to modem, regardless of the underlying
platform specific access mechanism.

* [PATCHv5 2/4] modem_shm: Register u8500 client for MAF
From: Arun Murthy @ 2012-10-15 5:28 UTC (permalink / raw)
To: linux-kernel, netdev, linux-doc, gregkh, alan; +Cc: Arun Murthy
In-Reply-To: <1350278920-25510-1-git-send-email-arun.murthy@stericsson.com>
Register with Modem Access Framework(MAF) for u8500 platform. This will provide
interface to enable and disable modem access and also provide the status.
