* [PATCH 5/5] sctp: Fix oops when sending queued ASCONF chunks
From: Vlad Yasevich @ 2010-04-28 18:47 UTC (permalink / raw)
To: netdev; +Cc: davem, linux-sctp, Vlad Yasevich, Yuansong Qiao, Shuaijun Zhang
In-Reply-To: <1272480442-32673-1-git-send-email-vladislav.yasevich@hp.com>
When we finish processing ASCONF_ACK chunk, we try to send
the next queued ASCONF. This action runs the sctp state
machine recursively and it's not prepared to do so.

* [PATCH 4/5] sctp: fix to calc the INIT/INIT-ACK chunk length correctly is set
From: Vlad Yasevich @ 2010-04-28 18:47 UTC (permalink / raw)
To: netdev; +Cc: davem, linux-sctp, Wei Yongjun, Vlad Yasevich
In-Reply-To: <1272480442-32673-1-git-send-email-vladislav.yasevich@hp.com>
From: Wei Yongjun <yjwei@cn.fujitsu.com>
When calculating the INIT/INIT-ACK chunk length, we should not
only account the length of parameters, but also the parameters
zero padding length, such as AUTH HMACS parameter and CHUNKS
parameter. Without the parameters zero padding length we may get
following oops.

* [PATCH 1/5] sctp: avoid irq lock inversion while call sk->sk_data_ready()
From: Vlad Yasevich @ 2010-04-28 18:47 UTC (permalink / raw)
To: netdev; +Cc: davem, linux-sctp, Wei Yongjun, Vlad Yasevich
In-Reply-To: <1272480442-32673-1-git-send-email-vladislav.yasevich@hp.com>
From: Wei Yongjun <yjwei@cn.fujitsu.com>
sk->sk_data_ready() of sctp socket can be called from both BH and non-BH
contexts, but the default sk->sk_data_ready(), sock_def_readable(), can
not be used in this case. Therefore, we have to make a new function
sctp_data_ready() to grab sk->sk_data_ready() with BH disabling.
=========================================================
[ INFO: possible irq lock inversion dependency detected ]

sctp_darn/1517 just changed the state of lock:

but this lock took another, SOFTIRQ-unsafe lock in the past:

and interrupts could create inverse lock ordering between them.

When sctp attempts to update an assocition, it removes any
addresses that were not in the updated INITs. However, the loop
may attempt to refrence a transport with address after removing it.

The code is correct. I probably confused you with earlier patches trying to
accommodate master/slave devices and you might have assumed enic was such a
device. But it's not. For enic, there are two device IDs, let's call one
"static" and the other "dynamic". The only difference between the two is
static enics load up fully ready to go just like a normal nic, whereas
dynamic enics load up but can't yet pass traffic because they're not
"plugged in" to the network. To plug them in, you need to associate a
port-profile. The physical analogy is this: server admin tells network
admin: plug my nic into a switch port with these characteristics. Here, the
port-profile describes those switch port characteristics. Now, there is no
master/slave relationship between static and dynamic enics. There could be
with a simple firmware update, but it's not there today. Also, I want to
point out that a single phys Cisco nic can be provisioned to expose many
static and/or many dynamic enics to the host. On the order of 100s. The
code above is to block port-profile association on static enics. Static
enics where already provisioned on the network when created so there is no
need for a port-profile push from the host.

For port-profile, we want to pass the device that is to be "plugged-in" to
the network based on port-profile association. This is the device that
gives basic connectivity to the guest interface, regardless of how the guest
interface is wired to the device. It could be direct PCI pass-thru, macvtap
stack, some yet-to-be-invented kernel-bypass stack, etc.

That's not a limitation of our device/switch.

Why than adding another check step, why not just keep going until

Hmmm... I am not convinced that this is a false positive. Couldn't
there be a multi-threaded process where one thread is invoking poll()
on a UNIX socket just as another thread is calling close() on it?
The current fcheck_files() logic requires that the caller either (1) be in
an RCU read-side critical section, (2) hold ->files_lock, or (3) passing
in a files_struct with ->count equal to 1 (initialization or cleanup).
So I don't feel comfortable just slapping an RCU read-side critical
section around this one, at least not unless someone who understands
the locking says that doing so is OK.
Thanx, Paul

It might be better to test the comparisons using
a cpu_to_le32 of the constants.

Hi Neil
I am also not crazy about the pre-allocation scheme. In the case where you have
say 100 parameters that are all 'skip' parameters, you'd end up pre-allocating a
huge buffer for absolutely nothing.
This is another point toward a fixed error chunk size and let parameter
processing allocate it when it reaches a parameter that needs an error.

That's there in my patch. If you don't specify anything after port-profile
keyword, it's an unset. See extra "[" and "]" above. Will that work for
you?

Ok, let's add an option flag bit field. I'm not sure how that looks from
the iproute2 cmd line. Would you take a stab at defining these?

PORT-PROFILE above is a u8* array. You could decide to encode the tuple in
a string, e.g. "1.12345.1", and let the receiver parse it? Or pack it in as
binary. PORT-PROFILE for us is just a string identifier, e.g. "corp-net-10"
or "joes-garage".

I don't think I have enough information to spec this out for this item.
Would you take a stab at how this would look in the struct and how it would
look from the iproute2 cmd line? (Note I'm using iproute2 cmd line for
illustrative purposes, but the sender of the msg could be something like
libvirt).

There is a status code in the get cmd as defined in my patch. I have it as
a u8 with some enum codes. Can we add to the enum code list? Or do you
want to return a full string? Our requirements are we return one of:
{success, error, in-progress}.

Wait a second...I abandoned iovnl and moved to if_link based on suggestions
from you and others. On 4/21/10 2:13 PM, "Arnd Bergmann" <arnd@arndb.de>

My latest with if_link fits best with what we're trying to do with enic.
Note the current interface is per netdev interface (a link), where the
netdev interface could be the adapter itself or any other netdev such as
macvlan, bond, etc.

If we want to break port_profile out into it's own ip cmd, I'm ok with that.
What you have above would work for enic. The netdev would have these ops:
ndo_set_port_profile
ndo_get_port_profile
ndo_del_port_profile
Sounds OK?

* Re: [PATCH]: sctp: Fix skb_over_panic resulting from multiple invalid parameter errors (CVE-2010-1173) (v2)
From: Neil Horman @ 2010-04-28 17:47 UTC (permalink / raw)

Ok, version 2.
Change notes:
1) in sctp_verify_init, when pre-allocating error chunk, limit size to pathmtu
of init chunk, or 1500 bytes (DEFAULT_MAXSEGMENT) if no pathmtu is discovered
yet or is otherwise unknown.
2) in process_unk_param, check to make sure we can add the next error chunk,
plus data in prior to adding. If there isn't enough room, discard it, as per
rfc allowances.

Its an skb_over_panic BUG halt that results from processing an init chunk in
which too many of its variable length parameters are in some way malformed.
The problem is in sctp_process_unk_param:
if (NULL == *errp)
*errp = sctp_make_op_error_space(asoc, chunk,
ntohs(chunk->chunk_hdr->length));
if (*errp) {
sctp_init_cause(*errp, SCTP_ERROR_UNKNOWN_PARAM,
WORD_ROUND(ntohs(param.p->length)));
sctp_addto_chunk(*errp,
WORD_ROUND(ntohs(param.p->length)),
param.v);
When we allocate an error chunk, we assume that the worst case scenario requires
that we have chunk_hdr->length data allocated, which would be correct nominally,
given that we call sctp_addto_chunk for the violating parameter. Unfortunately,
we also, in sctp_init_cause insert a sctp_errhdr_t structure into the error
chunk, so the worst case situation in which all parameters are in violation
requires chunk_hdr->length+(sizeof(sctp_errhdr_t)*param_count) bytes of data.
The result of this error is that a deliberately malformed packet sent to a
listening host can cause a remote DOS, described in CVE-2010-1173:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=2010-1173
I've tested the below fix and confirmed that it fixes the issue. It
pre-allocates the error chunk in sctp_verify_init, where we are able to count
the total number of variable length parameters, so we know how many error
headers we might need. Then we simply use that chunk, if we find an error, or
discard/free it if all the parameters are valid. Applies on top of the
lksctp-dev tree

Hmm, this wont work because we dont know this sk socket will serve as a
listener.
bind(... port=80);
listen(...) or connect(...)
David, I think we should revert patches for linux-2.6, and work on this
problem more closely on net-next-2.6
