sctp data size should be calculated by subtracting data chunk header's

We shouldn't abuse exceptions: if the destination MTU is already higher

Other than asoc pmtu sync from all transports, sctp_assoc_sync_pmtu
is also processing transport pmtu_pending by icmp packets. But it's
meaningless to use sctp_dst_mtu(t->dst) as new pmtu for a transport.
The right pmtu value should come from the icmp packet, and it would
be saved into transport->mtu_info in this patch and used later when
the pmtu sync happens in sctp_sendmsg_to_asoc or sctp_packet_config.
Besides, without this patch, as pmtu can only be updated correctly
when receiving a icmp packet and no place is holding sock lock, it
will take long time if the sock is busy with sending packets.
Note that it doesn't process transport->mtu_info in .release_cb(),
as there is no enough information for pmtu update, like for which
asoc or transport. It is not worth traversing all asocs to check
pmtu_pending. So unlike tcp, sctp does this in tx path, for which
mtu_info needs to be atomic_t.

When commit 270972554c91 ("[IPV6]: ROUTE: Add Router Reachability
Probing (RFC4191).") introduced router probing, the rt6_probe() function
required that a neighbour entry existed. This neighbour entry is used to
record the timestamp of the last probe via the ->updated field.
Later, commit 2152caea7196 ("ipv6: Do not depend on rt->n in rt6_probe().")
removed the requirement for a neighbour entry. Neighbourless routes skip
the interval check and are not rate-limited.
This patch adds rate-limiting for neighbourless routes, by recording the
timestamp of the last probe in the fib6_info itself.

Since commit 5aad1de5ea2c ("ipv4: use separate genid for next hop
exceptions"), exceptions get deprecated separately from cached
routes. In particular, administrative changes don't clear PMTU anymore.
As Stefano described in commit e9fa1495d738 ("ipv6: Reflect MTU changes
on PMTU of exceptions for MTU-less routes"), the PMTU discovered before
the local MTU change can become stale:
- if the local MTU is now lower than the PMTU, that PMTU is now
incorrect
- if the local MTU was the lowest value in the path, and is increased,
we might discover a higher PMTU
Similarly to what commit e9fa1495d738 did for IPv6, update PMTU in those
cases.
If the exception was locked, the discovered PMTU was smaller than the
minimal accepted PMTU. In that case, if the new local MTU is smaller
than the current PMTU, let PMTU discovery figure out if locking of the
exception is still needed.
To do this, we need to know the old link MTU in the NETDEV_CHANGEMTU
notifier. By the time the notifier is called, dev->mtu has been
changed. This patch adds the old MTU as additional information in the
notifier structure, and a new call_netdevice_notifiers_u32() function.

Devlink string param buffer is allocated at the size of
DEVLINK_PARAM_MAX_STRING_VALUE. Add helper function which makes sure
this size is not exceeded.
Renamed DEVLINK_PARAM_MAX_STRING_VALUE to
__DEVLINK_PARAM_MAX_STRING_VALUE to emphasize that it should be used by
devlink only. The driver should use the helper function instead to
verify it doesn't exceed the allowed length.

Timer handlers do not imply rcu_read_lock(), so my recent fix
triggered a LOCKDEP warning when SYNACK is retransmit.
Lets add rcu_read_lock()/rcu_read_unlock() pairs around ireq->ireq_opt
usages instead of guessing what is done by callers, since it is
not worth the pain.
Get rid of ireq_opt_deref() helper since it hides the logic
without real benefit, since it is now a standard rcu_dereference().

In normal SYN processing, packets are handled without listener
lock and in RCU protected ingress path.
But syzkaller is known to be able to trick us and SYN
packets might be processed in process context, after being
queued into socket backlog.
In commit 06f877d613be ("tcp/dccp: fix other lockdep splats
accessing ireq_opt") I made a very stupid fix, that happened
to work mostly because of the regular path being RCU protected.
Really the thing protecting ireq->ireq_opt is RCU read lock,
and the pseudo request refcnt is not relevant.
This patch extends what I did in commit 449809a66c1d ("tcp/dccp:
block BH for SYN processing") by adding an extra rcu_read_{lock|unlock}
pair in the paths that might be taken when processing SYN from
socket backlog (thus possibly in process context)

According to ETSI TS 102 622 specification chapter 4.4 pipe identifier
is 7 bits long which allows for 128 unique pipe IDs. Because
NFC_HCI_MAX_PIPES is used as the number of pipes supported and not
as the max pipe ID, its value should be 128 instead of 127.
nfc_hci_recv_from_llc extracts pipe ID from packet header using
NFC_HCI_FRAGMENT(0x7F) mask which allows for pipe ID value of 127.
Same happens when NCI_HCP_MSG_GET_PIPE() is being used. With
pipes array having only 127 elements and pipe ID of 127 the OOB memory
access will result.

Netfilter fixes for net
The following patchset contains Netfilter fixes for you net tree:
1) Remove duplicated include at the end of UDP conntrack, from Yue Haibing.
2) Restore conntrack dependency on xt_cluster, from Martin Willi.
3) Fix splat with GSO skbs from the checksum target, from Florian Westphal.
4) Rework ct timeout support, the template strategy to attach custom timeouts
is not correct since it will not work in conjunction with conntrack zones
and we have a possible free after use when removing the rule due to missing
refcounting. To fix these problems, do not use conntrack template at all
and set custom timeout on the already valid conntrack object. This
fix comes with a preparation patch to simplify timeout adjustment by
initializating the first position of the timeout array for all of the
existing trackers. Patchset from Florian Westphal.
5) Fix missing dependency on from IPv4 chain NAT type, from Florian.
6) Release chain reference counter from the flush path, from Taehee Yoo.
7) After flushing an iptables ruleset, conntrack hooks are unregistered
and entries are left stale to be cleaned up by the timeout garbage
collector. No TCP tracking is done on established flows by this time.
If ruleset is reloaded, then hooks are registered again and TCP
tracking is restored, which considers packets to be invalid. Clear
window tracking to exercise TCP flow pickup from the middle given that
history is lost for us. Again from Florian.
8) Fix crash from netlink interface with CONFIG_NF_CONNTRACK_TIMEOUT=y
and CONFIG_NF_CT_NETLINK_TIMEOUT=n.
9) Broken CT target due to returning incorrect type from
ctnl_timeout_find_get().
10) Solve conntrack clash on NF_REPEAT verdicts too, from Michal Vaner.
11) Missing conversion of hashlimit sysctl interface to new API, from

Using a private template is problematic:
1. We can't assign both a zone and a timeout policy
(zone assigns a conntrack template, so we hit problem 1)
2. Using a template needs to take care of ct refcount, else we'll
eventually free the private template due to ->use underflow.
This patch reworks template policy to instead work with existing conntrack.
As long as such conntrack has not yet been placed into the hash table
(unconfirmed) we can still add the timeout extension.
The only caveat is that we now need to update/correct ct->timeout to
reflect the initial/new state, otherwise the conntrack entry retains the
default 'new' timeout.
Side effect of this change is that setting the policy must
now occur from chains that are evaluated *after* the conntrack lookup
has taken place.
No released kernel contains the timeout policy feature yet, so this change
should be ok.
Changes since v2:
- don't handle 'ct is confirmed case'
- after previous patch, no need to special-case tcp/dccp/sctp timeout
anymore

Make wmm_rule be part of the reg_rule structure. This simplifies the
code a lot at the cost of having bigger memory usage. However in most
cases we have only few reg_rule's and when we do have many like in
iwlwifi we do not save memory as it allocates a separate wmm_rule for
each channel anyway.
This also fixes a bug reported in various places where somewhere the
pointers were corrupted and we ended up doing a null-dereference.

The new tcf_exts_for_each_action() macro doesn't reference its
arguments when CONFIG_NET_CLS_ACT is disabled, which leads to
a harmless warning in at least one driver:
drivers/net/ethernet/stmicro/stmmac/stmmac_tc.c: In function 'tc_fill_actions':
drivers/net/ethernet/stmicro/stmmac/stmmac_tc.c:64:6: error: unused variable 'i' [-Werror=unused-variable]
Adding a cast to void lets us avoid this kind of warning.
To be on the safe side, do it for all three arguments, not
just the one that caused the warning.

Pull core signal handling updates from Eric Biederman:
"It was observed that a periodic timer in combination with a
sufficiently expensive fork could prevent fork from every completing.
This contains the changes to remove the need for that restart.
This set of changes is split into several parts:
- The first part makes PIDTYPE_TGID a proper pid type instead
something only for very special cases. The part starts using
PIDTYPE_TGID enough so that in __send_signal where signals are
actually delivered we know if the signal is being sent to a a group
of processes or just a single process.
- With that prep work out of the way the logic in fork is modified so
that fork logically makes signals received while it is running
appear to be received after the fork completes"

All ops->delete() wants is getting the tn->idrinfo, but we already
have tc_action before calling ops->delete(), and tc_action has
a pointer ->idrinfo.
More importantly, each type of action does the same thing, that is,
just calling tcf_idr_delete_index().
So it can be just removed.

====================
pull-request: bpf 2018-08-18
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a BPF selftest failure in test_cgroup_storage due to rlimit
restrictions, from Yonghong.
2) Fix a suspicious RCU rcu_dereference_check() warning triggered
from removing a device's XDP memory allocator by using the correct
rhashtable lookup function, from Tariq.
3) A batch of BPF sockmap and ULP fixes mainly fixing leaks and races
as well as enforcing module aliases for ULPs. Another fix for BPF
map redirect to make them work again with tail calls, from Daniel.
4) Fix XDP BPF samples to unload their programs upon SIGTERM, from Jesper.

Lets not turn the TCP ULP lookup into an arbitrary module loader as
we only intend to load ULP modules through this mechanism, not other
unrelated kernel modules:
[root@bar]# cat foo.c
#include <sys/types.h>
#include <sys/socket.h>
#include <linux/tcp.h>
#include <linux/in.h>
int main(void)
{
int sock = socket(PF_INET, SOCK_STREAM, 0);
setsockopt(sock, IPPROTO_TCP, TCP_ULP, "sctp", sizeof("sctp"));
return 0;
}
[root@bar]# gcc foo.c -O2 -Wall
[root@bar]# lsmod | grep sctp
[root@bar]# ./a.out
[root@bar]# lsmod | grep sctp
sctp 1077248 4
libcrc32c 16384 3 nf_conntrack,nf_nat,sctp
[root@bar]#
Fix it by adding module alias to TCP ULP modules, so probing module
via request_module() will be limited to tcp-ulp-[name]. The existing
modules like kTLS will load fine given tcp-ulp-tls alias, but others
will fail to load:
[root@bar]# lsmod | grep sctp
[root@bar]# ./a.out
[root@bar]# lsmod | grep sctp
[root@bar]#
Sockmap is not affected from this since it's either built-in or not.

In order to determine allocation size of set, ->privsize is invoked.
At this point, both desc->size and size of each data structure of set
are used. desc->size means number of element that is given by user.
desc->size is u32 type. so that upperlimit of set element is 4294967295.
but return type of ->privsize is also u32. hence overflow can occurred.
test commands:
%nft add table ip filter
%nft add set ip filter hash1 { type ipv4_addr \; size 4294967295 \; }
%nft list ruleset
splat looks like:

- Re-enable ASPM in r8169, from Kai-Heng Feng.
- Add virtual XFRM interfaces, which avoids all of the limitations of
existing IPSEC tunnels. From Steffen Klassert.
- Convert GRO over to use a hash table, so that when we have many
flows active we don't traverse a long list during accumluation.
- Many new self tests for routing, TC, tunnels, etc. Too many
contributors to mention them all, but I'm really happy to keep
seeing this stuff.
- Hardware timestamping support for dpaa_eth/fsl-fman from Yangbo Lu.

Pull audit patches from Paul Moore:
"Twelve audit patches for v4.19 and they run the full gamut from fixes
to features.
Notable changes include the ability to use the "exe" audit filter
field in a wider variety of filter types, a fix for our comparison of
GID/EGID in audit filter rules, better association of related audit
records (connecting related audit records together into one audit
event), and a fix for a potential use-after-free in audit_add_watch().
All the patches pass the audit-testsuite and merge cleanly on your
current master branch"
