ipvs: initialize returned data in do_ip_vs_get_ctl
As reported by a gcc warning, the do_ip_vs_get_ctl does not initalize
all the members of the ip_vs_timeout_user structure it returns if
at least one of the TCP or UDP protocols is disabled for ipvs.
This makes sure that the data is always initialized, before it is
returned as a response to IPVS_CMD_GET_CONFIG or printed as a
debug message in IPVS_CMD_SET_CONFIG.
Without this patch, building ARM ixp4xx_defconfig results in:
net/netfilter/ipvs/ip_vs_ctl.c: In function 'ip_vs_genl_set_cmd':
net/netfilter/ipvs/ip_vs_ctl.c:2238:47: warning: 't.udp_timeout' may be used uninitialized in this function [-Wuninitialized]

Probably nobody noticed, because TCP stack retransmits packets
eventually.
But this adds unexpected latencies.
I'll send a patch.

Yes, i also expect to be able to include the link level header when i
use SOCK_RAW.
My intention is to send a frame with this payload (for example) :
typedef struct
{
double ts;
uint64_t foo;
} test_t;
So i get a pointer to the raw packet :
void * raw_packet = frame_base + (TPACKET_HDRLEN - sizeof(struct
sockaddr_ll));
I cook the header :
memcpy(raw_packet + 0, dst_addr, sizeof(dst_addr));
memcpy(raw_packet + 6, src_addr, sizeof(src_addr));
memcpy(raw_packet + 12, type , sizeof(type));
Then i get a pointer to the beginning of payload :
test_t * payload = raw_packet + 14;
Here payload is at 58 bytes from the beginning of the frame.
Then i fill the payload :
payload->ts = 1.0;
payload->foo = 2;
...
These are misaligned accesses.
I don't care to fill the cooked header if it's misaligned, but i would
like to be able to fill the frame directly in the ring buffer being on
aligned boundaries.
It would allow to avoid to memcpy an instance of the payload
structure...
Regards.
Paul.

That is what we want. If you plan another submission
you can add empty line before this memset and to replace
the __ip_vs_get_timeouts call in ip_vs_genl_set_config with
memset but they are cosmetic changes. Or may be Simon will
take care about the coding style when applying the change.

I don't try to read too much into our defconfigs. We have 140 of them
on ARM, and they are mainly useful to give a reasonable build coverage,
but I wouldn't expect them to be actually used on that hardware.
I'll leave it up to Krzysztof to send a patch for this if he wants.

I'd prefer Simon to pick up the patch. He should also decide whether he wants
to add it to stable. In theory, this is a small leak of kernel stack data
to user space, but as you say in practice it should not happen because it
only exists for silly configurations that nobody should be using.
AFAICT, removing the call to __ip_vs_get_timeouts in do_ip_vs_get_ctl would
be a semantic change for the case where a user sends a IPVS_CMD_SET_CONFIG
message without without the complete set of attributes inside it. The current
behavior is to leave the timeouts alone, replacing the __ip_vs_get_timeouts
with a memset would zero them. I left this part alone then.

8<-----
ipvs: initialize returned data in do_ip_vs_get_ctl
As reported by a gcc warning, the do_ip_vs_get_ctl does not initalize
all the members of the ip_vs_timeout_user structure it returns if
at least one of the TCP or UDP protocols is disabled for ipvs.
This makes sure that the data is always initialized, before it is
returned as a response to IPVS_CMD_GET_CONFIG or printed as a
debug message in IPVS_CMD_SET_CONFIG.
Without this patch, building ARM ixp4xx_defconfig results in:

Yeah we should definitely do a flush in that case. Thanks!

7c236c43b838221e17220bcb39e8e8d8c7123713 does something like the patch

The failure is due to the CONFIG_PPS is not set there, consequently
CONFIG_PTP_1588_CLOCK can not be set as =y anyway.
So David's patch of "da1586461e53a4dd045738cce309ab488970f0ef [1/9] pch_gbe:
Fix PTP dependencies" is buggy. Furthermore, I think using "selects" to
resolve such dependency issue is not good idea as it won't visit the dependencies.
David, I would still suggest to take my original patch:
https://lkml.org/lkml/2012/9/28/70

* [PATCH] pppoatm: don't send frames to destroyed vcc
From: Krzysztof Mazur @ 2012-10-06 12:19 UTC (permalink / raw)
To: mitch, netdev; +Cc: davem, linux-kernel, dwmw2, Krzysztof Mazur
The pppoatm_send() uses vcc->send() directly and does not check if vcc
is ready for send(). This causes Oops when send() is used after
vcc_destroy_socket() at least with usbatm driver:

This bug can be easily triggered with 9d02daf754238adac48fa075ee79e7edd3d79ed3
(pppoatm: Fix excessive queue bloat) present in Linux >= 3.5-rc1.
Steps to reproduce (tested with 9d02daf75 and v3.6):
$ ping -i 0.1 some.host.via.modem &
unplug ADSL line
sleep 3
plug ADSL line
The Oops occurs almost always.
On Linux v3.0.44, v3.4.12 the above steps did not trigger the bug, but
I saw similar Oops also on kernels < 3.5-rc1, but I was never able to
reproduce it or save kernel log.
This bug also exists in some stable kernels.
Maybe it's better to drop frame:
if (..) {
kfree_skb(skb);
return 1;
}
instead of
goto nospace;
The full Oops + some logs from Linux 3.6.0 with some minor changes
(copying kernel log to VRAM after crash and enabled usbatm debugging with
some additional debug).

Yeah, I guess the confusion came from cdb_size and sense_size being in
configuration space.

It is, but we can add a rule that if the (transport) flag
VIRTIO_RING_F_ANY_HEADER_SG is set, the cdb field is always 32 bytes in
virtio-blk.

Why should the user have to know a detail like the underlying
PTP chip type just to enable PTP on his networking card?
Because that is what you are making him do with your change.
Select removed the necessity of the user having to know these
things.

They use select and it should work here too, I don't want to
force users to have to know about an obscure PTP chip type
in order to enable PTP for their networking card.
It should be completely hidden from them.
That's why we should use select for this.

And what locking prevents the flag from being set immediately after we

However it possibly breaks the build...
IMHO, the reason why the dependency of PCH_PTP becomes so tricky is that the
code of these two modules call the functions of each other (bad code
structure?). To fix it neatly, either we restructure the code or just simply
make it:
+ depends on PTP_1588_CLOCK_PCH=y
For PCH_GBE=m case, it does be able to pass the build test, but I'm afraid it
won't be smoothly workable via "insmod" due to the codependency of these two
when PCH_PTP is enabled.

Then why does it work for IXGBE and others who use select?

Yes, that is the source of the problem. I don't recall how this habit
of having the PTP option as a module got started (and I hope it wasn't
me), but I think the right way to handle this option is with a simple
boolean connected to ifdefs for the MAC driver.
Come to think of it, it may have all started with the gianfar ptp
module. In principle, the time stamping function of a MAC driver can
be completely separate from the clock function, and indeed that is how
the pair of gianfar drivers work.
But for other hardware, it might not be practical to keep the
functions separate, and in that case I would say, just keep it as one
driver.
Thanks,
Richard

nothing, this patch should fix this.
The vcc_sendmsg() uses lock_sock(sk). This lock is used by
vcc_release(), so vcc_destroy_socket() will not be called between
check and during ->send(). The vcc_release_async() sets ATM_VF_CLOSE,
but it should be safe to call ->send() after it, because
vcc->dev->ops->close() is not called.
The pppoatm_send() is called with bottom halfs disabled, so
bh_lock_sock() should be used instead of lock_sock().

I think there is another problem here. The pppoatm gets a reference
to atmvcc, but I don't see anything that protects against removal
of that vcc.
The vcc uses vcc->sk socket for reference counting, so sock_hold()
and sock_put() should be used by pppoatm.

<snip>
I believe I've solved it. We were not specifying a flowid. Debian
Squeeze in our test lab did not object but the production system in this
case is CentOS 5.7. I am guessing the older tc did not like the missing
flowid. We added flowid :1 and all started working. I am a little
confused though. What meaning does the flowid have on an ingress qdisc
and what is class 0:1? Thanks - John

They explicitly select all the possible dependencies if they are bug-free (I
didn't strictly check them).
Take IXGBE_PTP as example, it explicitly selects PPS, and also depends on
EXPERIMENTAL:
config IXGBE_PTP
bool "PTP Clock Support"
default n
depends on IXGBE && EXPERIMENTAL
select PPS
select PTP_1588_CLOCK
So if you stick to use "select" as the convention of such build issue fixing,
fengguang's build failure would be fixed by:
+ depends on EXPERIMENTAL
+ select PPS
+ select PTP_1588_CLOCK
would you prefer this way?

* [PATCH] net: gro: selective flush of packets
From: Eric Dumazet @ 2012-10-06 18:08 UTC (permalink / raw)
To: Herbert Xu; +Cc: David Miller, netdev, Jesse Gross, Tom Herbert, Yuchung Cheng
In-Reply-To: <20121006105618.GA28591@gondor.apana.org.au>
From: Eric Dumazet <edumazet@google.com>
Current GRO can hold packets in gro_list for almost unlimited
time, in case napi->poll() handler consumes its budget over and over.
In this case, napi_complete()/napi_gro_flush() are not called.
Another problem is that gro_list is flushed in non friendly way :
We scan the list and complete packets in the reverse order.
(youngest packets first, oldest packets last)
This defeats priorities that sender could have cooked.
Since GRO currently only store TCP packets, we dont really notice the
bug because of retransmits, but this behavior can add unexpected
latencies, particularly on mice flows clamped by elephant flows.
This patch makes sure no packet can stay more than 1 ms in queue, and
only in stress situations.
It also complete packets in the right order to minimize latencies.

* [RFC] ipv6: gro: IPV6_GRO_CB(skb)->proto problem
From: Eric Dumazet @ 2012-10-06 19:15 UTC (permalink / raw)
To: Herbert Xu; +Cc: David Miller, netdev
It seems IPV6_GRO_CB(skb)->proto can be destroyed in skb_gro_receive()
if a new skb is allocated (to serve as an anchor for frag_list)
At line 3049 we copy NAPI_GRO_CB() only (not the IPV6 specific part)
*NAPI_GRO_CB(nskb) = *NAPI_GRO_CB(p);
So we leave IPV6_GRO_CB(nskb)->proto to 0 (fresh skb allocation) instead
of PROTO_TCP
So ipv6_gro_complete() wont be able to call ops->gro_complete()
[ tcp6_gro_complete() ]
I would fix this by moving proto in NAPI_GRO_CB() [ ie getting rid of
IPV6_GRO_CB ]
Am I missing something ?
(I'll submit a proper patch once/if prior GRO ones are accepted/merged
by David)
Thanks
