I have the same concerns here as I had for the sparc case.
Some of these drivers might be using IRQF_DISABLED to make sure the
IRQ cannot be delivered until it is explicitly enabled via an
enable_irq() call.
How is that being accomodated now?

Again IRQF_DISABLED never ever had that functionality.

My bad.
But what if these interrupts want interrupts disabled during their
interrupt handler, for other reasons?
This has the potential to break tons of stuff, especially on the
really old chips which almost no developers have any more but some
user might try to use.

We run ALL interrupt handlers with irqs disabled always.

It won't. We removed IRQF_DISABLED from kernel/irq/* long ago

Hi Matt!
No, I was just browsing the regression list and found this entry but
couldn't associate any action with it.
This clears that up, thanks for the information and I will close this

Eric,
Your updated patch looks good when I tested it on my side. It makes the
patch much more readable. If this patch looks good with you and Yan
Zheng, can you and Yan Zheng add your Signed-off-by to the patch?
Jiri, Sedat or Valdis, if you can verify that the patch fixed commit
0856a30409, that will be appreciated.
Eric, are you planning to do a fast path patch that doesn't do pid ref
for the case where CONFIG_PID_NS is not set?
Thanks.
Tim
---
Commit 0856a30409 (Scm: Remove unnecessary pid & credential references
in Unix socket's send and receive path) introduced a use-after-free bug.
The sent skbs from unix_stream_sendmsg could be consumed and destructed
by the receive side, removing all references to the credentials,
before the send side has finished sending out all
packets. However, send side could continue to consturct new packets in the
stream, using credentials that have lost its last reference and been
freed.
In this fix, we don't steal the reference to credentials we have obtained
in scm_send at beginning of unix_stream_sendmsg, till we've reached
the last packet. This fixes the problem in commit 0856a30409.

I mean:
[1] mmap()
[1] fill buffers
[1] pthread_create() [creates: 2]
[1] sendmsg() starts
[2] modify buffers
[1] sendmsg() returns
So: no multiple mmaps, and no touching of the fd. I haven't dug into
filesystem layer to see if threads affect file->f_count, but there
sure are no multiple mappings here.

Michał Mirosław

Replaced v2 with this patch (against next-20110831), I see now some
different call-traces which I did not see with v1 or v2.
Can't say if it's related to the new patch or not.

The memcg does not reserve memory. It provides upper bound limits on
memory usage. A careful admin can configure soft_limit_in_bytes as an
approximation of a memory reservation. But the soft limit is really
more like a reclaim target when there is global memory pressure.

Good question. Current upstream memcg user space memory limit does
not work for me today. I should have made that more obvious (sorry).

Now I see that you're using kmem to limit the amount of unreclaimable
kernel memory.
We have a work-in-progress patch series that adds kernel memory accounting to
memcg. These patches allow an admin to specify a single memory limit
for a cgroup which encompasses both user memory (as upstream memcg
does) and also includes many kernel memory allocations (especially
slab, page-tables). When kernel memory grows it puts pressure on user
memory; when user memory grows it puts pressure on reclaimable kernel
memory using registered shrinkers. We are in the process of cleaning
up these memcg slab accounting patches.
In my uses cases there is a single memory limit that applies to both
kernel and user memory. If a separate kmem cgroup is introduced to
manage kernel memory outside of memcg with a distinct limit, then I
would need a user space daemon which balances memory between the kmem
and memcg subsystems. As kmem grows, this daemon would apply pressure
to memcg, and as memcg grows pressure would be applied to kmem. As
you stated kernel memory is not necessarily reclaimable. So such
reclaim may fail. My resistance to this approach is that with a
single memory cgroup admins can do a better job packing a machine. If
balancing daemons are employed then more memory would need to be
reserved and more user space cpu time would be needed to apply VM
pressure between the types of memory.
While there are people (like me) who want a combined memory usage
limit there are also people (like you) who want separate user and
kernel limiting. I have toyed with the idea of having a per cgroup
flag that determines if kernel and user memory should be combined
charged against a single limit or if they should have separate limits.
I have also wondered if there was a way to wire the usage of two
subsystems together, then it would also meet meet my needs. But I am
not sure how to do that.

Sedat,
The previous patch should use the new steal_refs to check for the
release of scm references in the error handling at the end. I've
updated the patch to take care of it. Hopefully the traces you see will
go away. Can you verify?
Thanks.
Tim
----
Commit 0856a30409 (Scm: Remove unnecessary pid & credential references
in Unix socket's send and receive path) introduced a use-after-free bug.
The sent skbs from unix_stream_sendmsg could be consumed and destructed
by the receive side, removing all referentials to the credentials,
before the send side has finished sending out all
packets. However, send side could continue to consturct new packets in the
stream, using credentials that have lost its last reference and been
freed.
In this fix, we don't steal the reference to credentials we have obtained
in scm_send at beginning of unix_stream_sendmsg, till we've reached
the last packet. This fixes the problem in commit 0856a30409.

Will it break something if you define the helpers even if CONFIG_INET

It will be much cleaner. You can reuse ifdef CONFIG_CGROUP_KMEM in this
case.

not-yet-implemented things worry me. When can we expect this to
happen, and how big and ugly will it be?
I'm not seeing many (any) reviewed-by's on these patches. I could get
down and stare at them myself, but that wouldn't be very useful. This
work goes pretty deep and is quite security-affecting. And network-afecting.
Can you round up some suitable people and get the reviewing and testing happening
please?

* [RFC] interface for outgoing packet
From: Viral Mehta @ 2011-09-08 0:24 UTC (permalink / raw)
To: netdev
Hi All,
How reasonably I can assume that,
on whatever interface, I received the last packet
for a particular Socket Connection, the same interface will be
used to SEND the next packet for same socket connection?
I am collecting the logs on one of my test machines.
And it shows, I can assume all the time that "interface" which received packet
for some socket connection, the same will be used to send packet for
that connection
But, I am not sure if I am missing some scenarios
or setup (for e.g., bonding) where it can be wrong ?
It would be more help if some one can shed some light.

I think we should call scm_release() here in the case of
steal_refs == true. Otherwise siocb->scm->fp may leak.

Commit b9367bf3ee6d (net: ibmveth: convert to hw_features) reversed
a check in ibmveth_set_csum_offload that results in checksum offload
never being enabled.

* [PATCH 2/4] ibmveth: Fix issue with DMA mapping failure
From: Anton Blanchard @ 2011-09-08 0:41 UTC (permalink / raw)
To: Santiago Leon, brking, rcj; +Cc: netdev

[-- Attachment #1: ibmveth_dma_mapping_error.patch --]
[-- Type: text/plain, Size: 1604 bytes --]
descs[].fields.address is 32bit which truncates any dma mapping
errors so dma_mapping_error() fails to catch it.
Use a dma_addr_t to do the comparison. With this patch I was able
to transfer many gigabytes of data with IOMMU fault injection set
at 10% probability.

* [PATCH 4/4] ibmveth: Fix checksum offload failure handling
From: Anton Blanchard @ 2011-09-08 0:41 UTC (permalink / raw)
To: Santiago Leon, brking, rcj, mirq-linux; +Cc: netdev
In-Reply-To: <20110908004102.355674129@samba.org>
[-- Attachment #1: ibmveth_fix_csum2.patch --]
[-- Type: text/plain, Size: 2988 bytes --]
Fix a number of issues in ibmveth_set_csum_offload:
- set_attr6 and clr_attr6 may be used uninitialised
- We store the result of the IPV4 checksum change in ret but overwrite
it in a couple of places before checking it again later. Add ret4
to make it obvious what we are doing.
- We weren't clearing the NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM flags
if the enable of that hypervisor feature failed.

This patch could do with some review and I haven't marked it -stable
yet.
One thing that stands out is that we need to return an error back
through set_features if any feature bit gets changed.

Commit 6e8ab30ec677 (ibmveth: Add scatter-gather support) introduced a
DMA mapping API inconsistency resulting in dma_unmap_page getting
called on memory mapped via dma_map_single. This was seen when
CONFIG_DMA_API_DEBUG was enabled. Fix up this API usage inconsistency.
