commit 906b1c394d0906a154fbdc904ca506bceb515756 upstream.
The bitmask used for the prefix mangling was being calculated
incorrectly, leading to the wrong part of the address being replaced
when the prefix length wasn't a multiple of 32.

commit f83a7ea2075ca896f2dbf07672bac9cf3682ff74 upstream.
Alex Efros reported rpfilter module doesn't match following packets:
IN=br.qemu SRC=192.168.2.1 DST=192.168.2.255 [ .. ]
(netfilter bugzilla #814).
Problem is that network stack arranges for the locally generated broadcasts
to appear on the interface they were sent out, so the IFF_LOOPBACK check
doesn't trigger.
As -m rpfilter is restricted to PREROUTING, we can check for existing
rtable instead, it catches locally-generated broad/multicast case, too.

commit 442fad9423b78319e0019a7f5047eddf3317afbc upstream.
Userspace can cause kernel panic by not specifying orig/reply
tuple: kernel will create a tuple with random stack values.
Problem is that tuple.dst.dir will be random, too, which
causes nf_ct_tuplehash_to_ctrack() to return garbage.

commit 6e2f0aa8cf8892868bf2c19349cb5d7c407f690d upstream.
commit (32f5376 netfilter: nf_ct_helper: disable automatic helper
re-assignment of different type) broke transparent proxy scenarios.
For example, initial helper lookup might yield "ftp" (dport 21),
while re-lookup after REDIRECT yields "ftp-2121".
This causes the autoassign code to toss the ftp helper, even
though these are just different instances of the same helper.
Change the test to check for the helper function address instead
of the helper address, as suggested by Pablo.

commit dd82088dab3646ed28e4aa43d1a5b5d5ffc2afba upstream.
When an entry flagged with "nomatch" was tested by ipset, it
returned the error message "Kernel error received:
Directory not empty" instead of "<element> is NOT in set <setname>"
(reported by John Brendler).
The internal error code was not properly transformed before returning
to userspace, fixed.

packet
commit 3a7b21eaf4fb3c971bdb47a98f570550ddfe4471 upstream.
Some Cisco phones create huge messages that are spread over multiple packets.
After calculating the offset of the SIP body, it is validated to be within
the packet and the packet is dropped otherwise. This breaks operation of
these phones. Since connection tracking is supposed to be passive, just let
those packets pass unmodified and untracked.

Happens when a conntrack timeout expires right after first part
of the nat cleanup has completed (bysrc hash removal), but before

Patrick suggested to just remove the affected conntracks -- the
connections won't work properly anyway without nat transformation.
So, lets do that.

commit 990de49f74e772b6db5208457b7aa712a5f4db86 upstream.
When a full scan 2.4 and 5 GHz scan is scheduled, but then the 2.4 GHz
part of the scan disables a 5.2 GHz channel due to, e.g. receiving
country or frequency information, that 5.2 GHz channel might already
be in the list of channels to scan next. Then, when the driver checks
if it should do a passive scan, that will return false and attempt an
active scan. This is not only wrong but can also lead to the iwlwifi
device firmware crashing since it checks regulatory as well.
Fix this by not setting the channel flags to just disabled but rather
OR'ing in the disabled flag. That way, even if the race happens, the
channel will be scanned passively which is still (mostly) correct.

commit b20d34c458bc2bbd0a4624f2933581e01e72d875 upstream.
Since Stanislaw's patches, when suspending while connected,
cfg80211 will disconnect. This causes the AP station to be
removed, which uses call_rcu() to clean up. Due to needing
process context, this queues a work struct on the mac80211
workqueue. This will warn and fail when already suspended,
which can happen if the rcu call doesn't happen quickly.
To fix this, replace the synchronize_net() which is really
just synchronize_rcu_expedited() with rcu_barrier(), which
unlike synchronize_rcu() waits until RCU callback have run
and thus avoids this issue.
In theory, this can even happen without Stanislaw's change
to disconnect on suspend since userspace might disconnect
just before suspending, though then it's unlikely that the
call_rcu() will be delayed long enough.

[ Upstream commit 97599dc792b45b1669c3cdb9a4b365aad0232f65 ]
Commit 4a94445c9a5c (net: Use ip_route_input_noref() in input path)
added a bug in IP defragmentation handling, as non refcounted
dst could escape an RCU protected section.
Commit 64f3b9e203bd068 (net: ip_expire() must revalidate route) fixed
the case of timeouts, but not the general problem.
Tom Parkin noticed crashes in UDP stack and provided a patch,
but further analysis permitted us to pinpoint the root cause.
Before queueing a packet into a frag list, we must drop its dst,
as this dst has limited lifetime (RCU protected)
When/if a packet is finally reassembled, we use the dst of the very
last skb, still protected by RCU and valid, as the dst of the
reassembled packet.
Use same logic in IPv6, as there is no need to hold dst references.

[ Upstream commit c846ad9b880ece01bb4d8d07ba917734edf0324f ]
If one does do something unfortunate and allow a
bad offload bug into the kernel, this the
skb_warn_bad_offload can effectively live-lock the

[ Upstream commit 12fb3dd9dc3c64ba7d64cec977cca9b5fb7b1d4e ]
commit bd090dfc634d (tcp: tcp_replace_ts_recent() should not be called
from tcp_validate_incoming()) introduced a TS ecr bug in slow path
processing.
1 A > B P. 1:10001(10000) ack 1 <nop,nop,TS val 1001 ecr 200>
2 B < A . 1:1(0) ack 1 win 257 <sack 9001:10001,TS val 300 ecr 1001>
3 A > B . 1:1001(1000) ack 1 win 227 <nop,nop,TS val 1002 ecr 200>
4 A > B . 1001:2001(1000) ack 1 win 227 <nop,nop,TS val 1002 ecr 200>
(ecr 200 should be ecr 300 in packets 3 & 4)
Problem is tcp_ack() can trigger send of new packets (retransmits),
reflecting the prior TSval, instead of the TSval contained in the
currently processed incoming packet.
Fix this by calling tcp_replace_ts_recent() from tcp_ack() after the
checks, but before the actions.

[ Upstream commit 50bceae9bd3569d56744882f3012734d48a1d413 ]
If a TCP retransmission gets partially ACKed and collapsed multiple
times it is possible for the headroom to grow beyond 64K which will
overflow the 16bit skb->csum_start which is based on the start of
the headroom. It has been observed rarely in the wild with IPoIB due
to the 64K MTU.
Verify if the acking and collapsing resulted in a headroom exceeding
what csum_start can cover and reallocate the headroom if so.
A big thank you to Jim Foraker <foraker1@llnl.gov> and the team at
LLNL for helping out with the investigation and testing.

Here we do not respect sk->sk_bound_dev_if, therefore wrong dst_entry may be
taken. This dst_entry is used by new socket (get_cookie_sock ->
tcp_v4_syn_recv_sock), so its packets may take the wrong path.

[ Upstream commit 50a75a8914539c5dcd441c5f54d237a666a426fd ]
Tetja Rediske found that if the host receives an ICMPv6 redirect message
after sending a SYN+ACK, the connection will be reset.
He bisected it down to 093d04d (ipv6: Change skb->data before using
icmpv6_notify() to propagate redirect), but the origin of the bug comes
from ec18d9a26 (ipv6: Add redirect support to all protocol icmp error
handlers.). The bug simply did not trigger prior to 093d04d, because
skb->data did not point to the inner IP header and thus icmpv6_notify
did not call the correct err_handler.
This patch adds the missing "goto out;" in tcp_v6_err. After receiving
an ICMPv6 Redirect, we should not continue processing the ICMP in
tcp_v6_err, as this may trigger the removal of request-socks or setting
sk_err(_soft).

[ Upstream commit 124dff01afbdbff251f0385beca84ba1b9adda68 ]
Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code
to reset nf_trace in nf_reset(). This is wrong and unnecessary.
nf_reset() is used in the following cases:
- when passing packets up the the socket layer, at which point we want to
release all netfilter references that might keep modules pinned while
the packet is queued. nf_trace doesn't matter anymore at this point.
- when encapsulating or decapsulating IPsec packets. We want to continue
tracing these packets after IPsec processing.
- when passing packets through virtual network devices. Only devices on
that encapsulate in IPv4/v6 matter since otherwise nf_trace is not
used anymore. Its not entirely clear whether those packets should
be traced after that, however we've always done that.
- when passing packets through virtual network devices that make the
packet cross network namespace boundaries. This is the only cases
where we clearly want to reset nf_trace and is also what the
original patch intended to fix.
Add a new function nf_reset_trace() and use it in dev_forward_skb() to
fix this properly.

[ Upstream commit 0e82e7f6dfeec1013339612f74abc2cdd29d43d2 ]
It was reported that the following LSB test case failed
https://lsbbugs.linuxfoundation.org/attachment.cgi?id=2144 because we
were not coallescing unix stream messages when the application was
expecting us to.
The problem was that the first send was before the socket was accepted
and thus sock->sk_socket was NULL in maybe_add_creds, and the second
send after the socket was accepted had a non-NULL value for sk->socket
and thus we could tell the credentials were not needed so we did not
bother.
The unnecessary credentials on the first message cause
unix_stream_recvmsg to start verifying that all messages had the same
credentials before coallescing and then the coallescing failed because
the second message had no credentials.
Ignoring credentials when we don't care in unix_stream_recvmsg fixes a
long standing pessimization which would fail to coallesce messages when
reading from a unix stream socket if the senders were different even if
we did not care about their credentials.
I have tested this and verified that the in the LSB test case mentioned
above that the messages do coallesce now, while the were failing to
coallesce without this change.

[ Upstream commit 4543fbefe6e06a9e40d9f2b28d688393a299f079 ]
A few drivers use dev_uc_sync/unsync to synchronize the
address lists from master down to slave/lower devices. In
some cases (bond/team) a single address list is synched down
to multiple devices. At the time of unsync, we have a leak
in these lower devices, because "synced" is treated as a
boolean and the address will not be unsynced for anything after
the first device/call.
Treat "synced" as a count (same as refcount) and allow all
unsync calls to work.

[ Upstream commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f ]
IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo)
interface. After down-up, routes of other interface's IPv6 addresses through
'lo' are lost.
IPv6 addresses assigned to all interfaces are routed through 'lo' for internal
communication. Once 'lo' is down, those routing entries are removed from routing
table. But those removed entries are not being re-created properly when 'lo' is
brought up. So IPv6 addresses of other interfaces becomes unreachable from the
same machine. Also this breaks communication with other machines because of
NDISC packet processing failure.
This patch fixes this issue by reading all interface's IPv6 addresses and adding
them to IPv6 routing table while bringing up 'lo'.

[ Upstream commit f0f6ee1f70c4eaab9d52cf7d255df4bd89f8d1c2 ]
currently cbq works incorrectly for limits > 10% real link bandwidth,
and practically does not work for limits > 50% real link bandwidth.
Below are results of experiments taken on 1 Gbit link
In shaper | Actual Result
-----------+---------------
100M | 108 Mbps
200M | 244 Mbps
300M | 412 Mbps
500M | 893 Mbps
This happen because of q->now changes incorrectly in cbq_dequeue():
when it is called before real end of packet transmitting,
L2T is greater than real time delay, q_now gets an extra boost
but never compensate it.
To fix this problem we prevent change of q->now until its synchronization
with real time.

The code in set_orig_addr() does not initialize all of the members of
struct sockaddr_tipc when filling the sockaddr info -- namely the union
is only partly filled. This will make recv_msg() and recv_stream() --
the only users of this function -- leak kernel stack memory as the
msg_name member is a local variable in net/socket.c.
Additionally to that both recv_msg() and recv_stream() fail to update
the msg_namelen member to 0 while otherwise returning with 0, i.e.
"success". This is the case for, e.g., non-blocking sockets. This will
lead to a 128 byte kernel stack leak in net/socket.c.
Fix the first issue by initializing the memory of the union with
memset(0). Fix the second one by setting msg_namelen to 0 early as it
will be updated later if we're going to fill the msg_name member.

in l2tp_ip6_recvmsg() in case msg_name is set.
Initialize l2tp_conn_id with 0 to avoid the info leak.

[ Upstream commit a5598bd9c087dc0efc250a5221e5d0e6f584ee88 ]
The current code does not fill the msg_name member in case it is set.
It also does not set the msg_namelen member to 0 and therefore makes
net/socket.c leak the local, uninitialized sockaddr_storage variable
to userland -- 128 bytes of kernel stack memory.
Fix that by simply setting msg_namelen to 0 as obviously nobody cared
about iucv_sock_recvmsg() not filling the msg_name in case it was set.

[ Upstream commit c8c499175f7d295ef867335bceb9a76a2c3cdc38 ]
If the socket is in state BT_CONNECT2 and BT_SK_DEFER_SETUP is set in
the flags, sco_sock_recvmsg() returns early with 0 without updating the
possibly set msg_namelen member. This, in turn, leads to a 128 byte
kernel stack leak in net/socket.c.
Fix this by updating msg_namelen in this case. For all other cases it
will be handled in bt_sock_recvmsg().

[ Upstream commit 4683f42fde3977bdb4e8a09622788cc8b5313778 ]
In case the socket is already shutting down, bt_sock_recvmsg() returns
with 0 without updating msg_namelen leading to net/socket.c leaking the
local, uninitialized sockaddr_storage variable to userland -- 128 bytes
of kernel stack memory.
Fix this by moving the msg_namelen assignment in front of the shutdown
test.

[ Upstream commit ef3313e84acbf349caecae942ab3ab731471f1a1 ]
When msg_namelen is non-zero the sockaddr info gets filled out, as
requested, but the code fails to initialize the padding bytes of struct
sockaddr_ax25 inserted by the compiler for alignment. Additionally the
msg_namelen value is updated to sizeof(struct full_sockaddr_ax25) but is
not always filled up to this size.
Both issues lead to the fact that the code will leak uninitialized
kernel stack bytes in net/socket.c.
Fix both issues by initializing the memory with memset(0).

commit 7b119dc06d871405fc7c3e9a73a6c987409ba639 upstream.
If authentication (or association with FT) is requested by
userspace, mac80211 currently doesn't tell cfg80211 that it
disconnected from the AP. That leaves inconsistent state:
cfg80211 thinks it's connected while mac80211 thinks it's
not. Typically this won't last long, as soon as mac80211
reports the new association to cfg80211 the old one goes
away. If, however, the new authentication or association
doesn't succeed, then cfg80211 will forever think the old
one still exists and will refuse attempts to authenticate
or associate with the AP it thinks it's connected to.
Anders reported that this leads to it taking a very long
time to reconnect to a network, or never even succeeding.
I tested this with an AP hacked to never respond to auth
frames, and one that works, and with just those two the
system never recovers because one won't work and cfg80211
thinks it's connected to the other so refuses connections
to it.
To fix this, simply make mac80211 tell cfg80211 when it is
no longer connected to the old AP, while authenticating or
associating to a new one.

commit a58e0be6f6b3eb2079b0b8fedc9df6fa86869f1e upstream.
While testing error cases where rpc_new_client() fails, I saw
some oopses.
If rpc_new_client() fails, it already invokes xprt_put(). Thus
__rpc_clone_client() does not need to invoke it again.

commit 3fbd45ca8d1c98f3c2582ef8bc70ade42f70947b upstream.
If a ROC item is canceled just as it expires, the work
struct may be scheduled while it is running (and waiting
for the mutex). This results in it being run after being
freed, which obviously crashes.
To fix this don't free it when aborting is requested but
instead mark it as "to be freed", which makes the work a
no-op and allows freeing it outside.
