commit 78146572b9 upstream.
nfnl_cthelper_parse_tuple() is called from nfnl_cthelper_new(),
nfnl_cthelper_get() and nfnl_cthelper_del(). In each case they pass
a pointer to an nf_conntrack_tuple data structure local variable:
struct nf_conntrack_tuple tuple;
...
ret = nfnl_cthelper_parse_tuple(&tuple, tb[NFCTH_TUPLE]);
The problem is that this local variable is not initialized, and
nfnl_cthelper_parse_tuple() only initializes two fields: src.l3num and
dst.protonum. This leaves all other fields with undefined values
based on whatever is on the stack:
tuple->src.l3num = ntohs(nla_get_be16(tb[NFCTH_TUPLE_L3PROTONUM]));
tuple->dst.protonum = nla_get_u8(tb[NFCTH_TUPLE_L4PROTONUM]);
The symptom observed was that when the rpc and tns helpers were added
then traffic to port 1536 was being sent to user-space.

commit 330966e501 upstream.
skb_gso_segment has three possible return values:
1. a pointer to the first segmented skb
2. an errno value (IS_ERR())
3. NULL. This can happen when GSO is used for header verification.
However, several callers currently test IS_ERR instead of IS_ERR_OR_NULL
and would oops when NULL is returned.
Note that these call sites should never actually see such a NULL return
value; all callers mask out the GSO bits in the feature argument.
However, there have been issues with some protocol handlers erronously not
respecting the specified feature mask in some cases.
It is preferable to get 'have to turn off hw offloading, else slow' reports
rather than 'kernel crashes'.

commit db29a9508a upstream.
Given following iptables ruleset:
-P FORWARD DROP
-A FORWARD -m sctp --dport 9 -j ACCEPT
-A FORWARD -p tcp --dport 80 -j ACCEPT
-A FORWARD -p tcp -m conntrack -m state ESTABLISHED,RELATED -j ACCEPT
One would assume that this allows SCTP on port 9 and TCP on port 80.
Unfortunately, if the SCTP conntrack module is not loaded, this allows
*all* SCTP communication, to pass though, i.e. -p sctp -j ACCEPT,
which we think is a security issue.
This is because on the first SCTP packet on port 9, we create a dummy
"generic l4" conntrack entry without any port information (since
conntrack doesn't know how to extract this information).
All subsequent packets that are unknown will then be in established
state since they will fallback to proto_generic and will match the
'generic' entry.
Our originally proposed version [1] completely disabled generic protocol
tracking, but Jozsef suggests to not track protocols for which a more
suitable helper is available, hence we now mitigate the issue for in
tree known ct protocol helpers only, so that at least NAT and direction
information will still be preserved for others.

The kernel should reserve enough room in the skb so that the DONE

erronously not being size-accounted for, __nfulnl_send() will still

forever and blocking delivery of further messages.
Fix issue by releasing skb immediately after nlmsg_put error and
WARN() so we can track down the cause of such size mismatch.

An updater may interfer with the dumping of any of the object lists.
Fix this by using a per-net generation counter and use the
nl_dump_check_consistent() interface so the NLM_F_DUMP_INTR flag is set
to notify userspace that it has to restart the dump since an updater
has interfered.
This patch also replaces the existing consistency checking code in the
rule dumping path since it is broken. Basically, the value that the
dump callback returns is not propagated to userspace via
netlink_dump_start().
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
The dump operation through netlink is not protected by the nfnl_lock.
Thus, a reader process can be dumping any of the existing object
lists while another process can be updating the list content.
This patch resolves this situation by protecting all the object
lists with RCU in the netlink dump path which is the reader side.
The updater path is already protected via nfnl_lock, so use list
manipulation RCU-safe operations.

Quoting Samu Kallio:
Basically what's happening is, during netns cleanup,
nf_nat_net_exit gets called before ipv4_net_exit. As I understand
it, nf_nat_net_exit is supposed to kill any conntrack entries which
have NAT context (through nf_ct_iterate_cleanup), but for some
reason this doesn't happen (perhaps something else is still holding
refs to those entries?).
When ipv4_net_exit is called, conntrack entries (including those
with NAT context) are cleaned up, but the
nat_bysource hashtable is long gone - freed in nf_nat_net_exit. The
bug happens when attempting to free a conntrack entry whose NAT hash
'prev' field points to a slot in the freed hash table (head for that
bin).
We ignore conntracks with null nat bindings. But this is wrong,
as these are in bysource hash table as well.
Restore nat-cleaning for the netns-is-being-removed case.
