[ Upstream commit b9b312a7a451e9c098921856e7cfbc201120e1a7 ]
syzkaller reported crashes in IPv6 stack [1]
Xin Long found that lo MTU was set to silly values.
IPv6 stack reacts to changes to small MTU, by disabling itself under
RTNL.
But there is a window where threads not using RTNL can see a wrong
device mtu. This can lead to surprises, in mld code where it is assumed
the mtu is suitable.
Fix this by reading device mtu once and checking IPv6 minimal MTU.

[ Upstream commit b5476022bbada3764609368f03329ca287528dc8 ]
IPv4 stack reacts to changes to small MTU, by disabling itself under
RTNL.
But there is a window where threads not using RTNL can see a wrong
device mtu. This can lead to surprises, in igmp code where it is
assumed the mtu is suitable.
Fix this by reading device mtu once and checking IPv4 minimal MTU.
This patch adds missing IPV4_MIN_MTU define, to not abuse
ETH_MIN_MTU anymore.

In the commit 93557f53e1fb ("netfilter: nf_conntrack: nf_conntrack snmp
helper"), the snmp_helper is replaced by nf_nat_snmp_hook. So the
snmp_helper is never registered. But it still tries to unregister the
snmp_helper, it could cause the panic.
Now remove the useless snmp_helper and the unregister call in the
error handler.

[ Upstream commit 83d90219a5df8d950855ce73229a97b63605c317 ]
The nf_ct_helper_hash table is protected by nf_ct_helper_mutex, while
nfct_helper operation is protected by nfnl_lock(NFNL_SUBSYS_CTHELPER).
So it's possible that one CPU is walking the nf_ct_helper_hash for
cthelper add/get/del, another cpu is doing nf_conntrack_helpers_unregister
at the same time. This is dangrous, and may cause use after free error.
Note, delete operation will flush all cthelpers added via nfnetlink, so
using rcu to do protect is not easy.
Now introduce a dummy list to record all the cthelpers added via
nfnetlink, then we can walk the dummy list instead of walking the
nf_ct_helper_hash. Also, keep nfnl_cthelper_dump_table unchanged, it
may be invoked without nfnl_lock(NFNL_SUBSYS_CTHELPER) held.

[ Upstream commit 95f255211396958c718aef8c45e3923b5211ea7b ]
This change basically codifies what I think was already the limitations on
the busy_poll and busy_read sysctl interfaces. We weren't checking the
lower bounds and as such could input negative values. The behavior when
that was used was dependent on the architecture. In order to prevent any
issues with that I am just disabling support for values less than 0 since
this way we don't have to worry about any odd behaviors.
By limiting the sysctl values this way it also makes it consistent with how
we handle the SO_BUSY_POLL socket option since the value appears to be
reported as a signed integer value and negative values are rejected.

[ Upstream commit ec4fbd64751de18729eaa816ec69e4b504b5a7a2 ]
Dmitry reported a lockdep splat [1] (false positive) that we can fix
by releasing the spinlock before calling icmp_send() from ip_expire()
This is a false positive because sending an ICMP message can not
possibly re-enter the IP frag engine.

[ Upstream commit aea92fb2e09e29653b023d4254ac9fbf94221538 ]
skb_cow(skb, sizeof(ip header)) is not very helpful in this context.
First we need to use pskb_may_pull() to make sure the ip header
is in skb linear part, then use skb_try_make_writable() to
address clones issues.
Fixes: 4c30719f4f55 ("[PKT_SCHED] dsmark: handle cloned and non-linear skb's")

Subject: netlink: Annotate nlk cb_mutex by protocol
Currently all occurences of nlk->cb_mutex are annotated by lockdep
as a single class. This causes a false lcokdep cycle involving
genl and crypto_user.
This patch fixes it by dividing cb_mutex into individual classes
based on the netlink protocol. As genl and crypto_user do not
use the same netlink protocol this breaks the false dependency
loop.

[ Upstream commit 4dc12ffeaeac939097a3f55c881d3dc3523dff0c ]
l2tp_tunnel_delete does not return anything since commit 62b982eeb458
("l2tp: fix race condition in l2tp_tunnel_delete"). But call sites of
l2tp_tunnel_delete still do casts to void to avoid unused return value
warnings.
Kill these now useless casts.

[ Upstream commit c5504f724c86ee925e7ffb80aa342cfd57959b13 ]
Information about ipvs in different network namespace can be seen via procfs.
How to reproduce:
# ip netns add ns01
# ip netns add ns02
# ip netns exec ns01 ip a add dev lo 127.0.0.1/8
# ip netns exec ns02 ip a add dev lo 127.0.0.1/8
# ip netns exec ns01 ipvsadm -A -t 10.1.1.1:80
# ip netns exec ns02 ipvsadm -A -t 10.1.1.2:80
The ipvsadm displays information about its own network namespace only.
# ip netns exec ns01 ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.1.1.1:80 wlc
# ip netns exec ns02 ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.1.1.2:80 wlc
But I can see information about other network namespace via procfs.
# ip netns exec ns01 cat /proc/net/ip_vs
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 0A010101:0050 wlc
TCP 0A010102:0050 wlc
# ip netns exec ns02 cat /proc/net/ip_vs

[ Upstream commit 37c343b4f4e70e9dc328ab04903c0ec8d154c1a4 ]
When we notify peers of potential changes, it's also good to update
IGMP memberships. For example, during VM migration, updating IGMP
memberships will redirect existing multicast streams to the VM at the
new location.

[ Upstream commit 4ca60d08cbe65f501baad64af50fceba79c19fbb ]
consider a bridge with mtu 9000, but end host sending smaller
packets to another host with mtu < 9000.
In this case, after reassembly, bridge+defrag would refragment,
and then attempt to send the reassembled packet as long as it
was below 9k.
Instead we have to cap by the largest fragment size seen.

[ Upstream commit 9f138fa609c47403374a862a08a41394be53d461 ]
KMSAN reports a use of uninitialized memory in put_cmsg() because
msg.msg_flags in recvfrom haven't been initialized properly.
The flag values don't affect the result on this path, but it's still a
good idea to initialize them explicitly.

commit 57629915d568c522ac1422df7bba4bee5b5c7a7c upstream.
The code was setting the capabilities byte to zero,
after it was already properly set previously. Fix it.
The bug was found while debugging hwsim mesh tests failures
that happened since the commit mentioned below.
Fixes: 76f43b4c0a93 ("mac80211: Remove invalid flag operations in mesh TSF synchronization")

[ Upstream commit 15fe076edea787807a7cdc168df832544b58eba6 ]
syzbot reported crashes [1] and provided a C repro easing bug hunting.
When/if packet_do_bind() calls __unregister_prot_hook() and releases
po->bind_lock, another thread can run packet_notifier() and process an
NETDEV_UP event.
This calls register_prot_hook() and hooks again the socket right before
first thread is able to grab again po->bind_lock.
Fixes this issue by temporarily setting po->num to 0, as suggested by
David Miller.

syzkaller found a race condition fanout_demux_rollover() while removing
a packet socket from a fanout group.
po->rollover is read and operated on during packet_rcv_fanout(), via
fanout_demux_rollover(), but the pointer is currently cleared before the
synchronization in packet_release(). It is safer to delay the cleanup
until after synchronize_net() has been called, ensuring all calls to
packet_rcv_fanout() for this socket have finished.
To further simplify synchronization around the rollover structure, set
po->rollover in fanout_add() only if there are no errors. This removes
the need for rcu in the struct and in the call to
packet_getsockopt(..., PACKET_ROLLOVER_STATS, ...).

This is a fix for syzkaller719569, where memory registration was
attempted without any underlying transport being loaded.
Analysis of the case reveals that it is the setsockopt() RDS_GET_MR
(2) and RDS_GET_MR_FOR_DEST (7) that are vulnerable.

[ Upstream commit 0e74aa1d79a5bbc663e03a2804399cae418a0321 ]
The syzbot found an ancient bug in the IPsec code. When we cloned
a socket policy (for example, for a child TCP socket derived from a
listening socket), we did not copy the family field. This results
in a live policy with a zero family field. This triggers a BUG_ON
check in the af_key code when the cloned policy is retrieved.
This patch fixes it by copying the family field over.

[ Upstream commit cea0cc80a6777beb6eb643d4ad53690e1ad1d4ff ]
Commit dfcb9f4f99f1 ("sctp: deny peeloff operation on asocs with threads
sleeping on it") fixed the race between peeloff and wait sndbuf by
checking waitqueue_active(&asoc->wait) in sctp_do_peeloff().
But it actually doesn't work, as even if waitqueue_active returns false
the waiting sndbuf thread may still not yet hold sk lock. After asoc is
peeled off, sk is not asoc->base.sk any more, then to hold the old sk
lock couldn't make assoc safe to access.
This patch is to fix this by changing to hold the new sk lock if sk is
not asoc->base.sk, meanwhile, also set the sk in sctp_sendmsg with the
new sk.
With this fix, there is no more race between peeloff and waitbuf, the
check 'waitqueue_active' in sctp_do_peeloff can be removed.
Thanks Marcelo and Neil for making this clear.
v1->v2:
fix it by changing to lock the new sock instead of adding a flag in asoc.

[ Upstream commit ca3af4dd28cff4e7216e213ba3b671fbf9f84758 ]
Now in sctp_sendmsg sctp_wait_for_sndbuf could schedule out without
holding sock sk. It means the current asoc can be freed elsewhere,
like when receiving an abort packet.
If the asoc is just created in sctp_sendmsg and sctp_wait_for_sndbuf
returns err, the asoc will be freed again due to new_asoc is not nil.
An use-after-free issue would be triggered by this.
This patch is to fix it by setting new_asoc with nil if the asoc is
already dead when cpu schedules back, so that it will not be freed
again in sctp_sendmsg.
v1->v2:
set new_asoc as nil in sctp_sendmsg instead of sctp_wait_for_sndbuf.

[ Upstream commit e39d5246111399dbc6e11cd39fd8580191b86c47 ]
Now when creating fnhe for redirect, it sets fnhe_expires for this
new route cache. But when updating the exist one, it doesn't do it.
It will cause this fnhe never to be expired.
Paolo already noticed it before, in Jianlin's test case, it became
even worse:
When ip route flush cache, the old fnhe is not to be removed, but
only clean it's members. When redirect comes again, this fnhe will
be found and updated, but never be expired due to fnhe_expires not
being set.
So fix it by simply updating fnhe_expires even it's for redirect.

[ Upstream commit cebe84c6190d741045a322f5343f717139993c08 ]
Now when ip route flush cache and it turn out all fnhe_genid != genid.
If a redirect/pmtu icmp packet comes and the old fnhe is found and all
it's members but fnhe_genid will be updated.
Then next time when it looks up route and tries to rebind this fnhe to
the new dst, the fnhe will be flushed due to fnhe_genid != genid. It
causes this redirect/pmtu icmp packet acutally not to be applied.
This patch is to also reset fnhe_genid when updating a route cache.

[ Upstream commit 7b4fdf77a450ec0fdcb2f677b080ddbf2c186544 ]
Andrey reports syzkaller splat caused by
NF_CT_ASSERT(!ip_is_fragment(ip_hdr(skb)));
in ipv4 nat. But this assertion (and the comment) are wrong, this function
does see fragments when IP_NODEFRAG setsockopt is used.
As conntrack doesn't track packets without complete l4 header, only the
first fragment is tracked.
Because applying nat to first packet but not the rest makes no sense this
also turns off tracking of all fragments.

This is because net->ipv6.mr6_tables is not initialized at that point,
ip6mr_rules_init() is not called yet, therefore on the error path when

Add a sysctl nf_ipv4_defrag_skip to skip defragmentation per
interface. This is set 0 to preserve existing behavior (always
defrag per interface).
This is useful for pure ipv4 forwarding scenarios (without NAT)
in conjunction with xfrm. It appears that network stack defrags
the packets and then forwards them to xfrm which then encrypts
and then later fragments them on a different boundary compared
to the source.

commit 1137b5e2529a8f5ca8ee709288ecba3e68044df2 upstream.
An independent security researcher, Mohamed Ghannam, has reported
this vulnerability to Beyond Security's SecuriTeam Secure Disclosure
program.
The xfrm_dump_policy_done function expects xfrm_dump_policy to
have been called at least once or it will crash. This can be
triggered if a dump fails because the target socket's receive
buffer is full.
This patch fixes it by using the cb->start mechanism to ensure that
the initialisation is always done regardless of the buffer situation.
Fixes: 12a169e7d8f4 ("ipsec: Put dumpers on the dump list")

commit fc9e50f5a5a4e1fa9ba2756f745a13e693cf6a06 upstream.
The start callback allows the caller to set up a context for the
dump callbacks. Presumably, the context can then be destroyed in
the done callback.
