Magnus Damm [Fri, 3 Aug 2007 05:27:20 +0000]
sh: intc - convert voyagergx code

This patch converts the sh-specific voyagergx interrupt code to make use
of intc. A lot of "interesting" old cruft gets replaced with intc tables
and some simple demux code.

- All interrupt sources in the sm501 data sheet are now in the header.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 200.
- set_irq_chained_handler() is now used to hook up the demux function.

In the future it would probably make sense to move the interrupt demuxer
into into the mfd driver, but this is probably a nice step in the right
direction until that happens.

Tested on a R2D-1 board using the serial port hooked up to the sm501.

signalfd simplification

This simplifies signalfd code, by avoiding it to remain attached to the
sighand during its lifetime.

In this way, the signalfd remain attached to the sighand only during
poll(2) (and select and epoll) and read(2).  This also allows to remove
all the custom "tsk == current" checks in kernel/signal.c, since
dequeue_signal() will only be called by "current".

I think this is also what Ben was suggesting time ago.

The external effect of this, is that a thread can extract only its own
private signals and the group ones.  I think this is an acceptable
behaviour, in that those are the signals the thread would be able to

13 years ago[PPP] L2TP: Fix skb handling in pppol2tp_xmit
Herbert Xu [Wed, 19 Sep 2007 17:46:28 +0000]
[PPP] L2TP: Fix skb handling in pppol2tp_xmit

This patch makes pppol2tp_xmit call skb_cow_head so that we don't modify
cloned skb data.  It also gets rid of skb2 we only need to preserve the
original skb for congestion notification, which is only applicable for
ppp_async and ppp_sync.

The other semantic change made here is the removal of socket accounting
for data tranmitted out of pppol2tp_xmit.  The original code leaked any
existing socket skb accounting.  We could fix this by dropping the
original skb owner.  However, this is undesirable as the packet has not
physically left the host yet.

In fact, all other tunnels in the kernel do not account skb's passing
through to their own socket.  In partciular, ESP over UDP does not do
so and it is the closest tunnel type to PPPoL2TP.  So this patch simply
removes the socket accounting in pppol2tp_xmit.  The accounting still
applies to control packets of course.

I've also added a reminder that the outgoing checksum here doesn't work.
I suppose existing deployments don't actually enable checksums.

[PPP] L2TP: Fix skb handling in pppol2tp_recv_core

The function pppol2tp_recv_core doesn't handle non-linear packets properly.
It also fails to check the remote offset field.

This patch fixes these problems.  It also removes an unnecessary check on

The following patch fixes the handling of netlink packets containing
multiple messages.

As exposed during netfilter workshop, nfnetlink_log was overwritten the
message type of the last message (setting it to MSG_DONE) in a multipart
packet. The consequence was libnfnetlink to ignore the last message in the
packet.

the end of the netlink skb.

autocrlf=input

(which makes sense if you ever develop under Windows, for example, or if
you use other broken tools) in your git config, git will always complain
about the file being dirty.

sched: fix invalid sched_class use

When using rt_mutex, a NULL pointer dereference is occurred at
enqueue_task_rt. Here is a scenario;
1) there are two threads, the thread A is fair_sched_class and
   thread B is rt_sched_class.
2) Thread A is boosted up to rt_sched_class, because the thread A
   has a rt_mutex lock and the thread B is waiting the lock.
3) At this time, when thread A create a new thread C, the thread
   C has a rt_sched_class.
4) When doing wake_up_new_task() for the thread C, the priority
   of the thread C is out of the RT priority range, because the
   normal priority of thread A is not the RT priority. It makes
   data corruption by overflowing the rt_prio_array.
The new thread C should be fair_sched_class.

The new thread should be valid scheduler class before queuing.
This patch fixes to set the suitable scheduler class.
