net: fix up skbs delta_truesize in UDP GRO frag_list
commit 224102de2ff105a2c05695e66a08f4b5b6b2d19c upstream.
The truesize for a UDP GRO packet is added by main skb and skbs in main
skb's frag_list:
skb_gro_receive_list
p->truesize += skb->truesize;

bpf, sockmap: Do not ignore orig_len parameter
commit 60ce37b03917e593d8e5d8bcc7ec820773daf81d upstream.
Currently, sk_psock_verdict_recv() returns skb->len
This is problematic because tcp_read_sock() might have
passed orig_len < skb->len, due to the presence of TCP urgent data.
This causes an infinite loop from tcp_read_sock()
Followup patch will make tcp_read_sock() more robust vs bad actors.

net-timestamp: convert sk->sk_tskey to atomic_t
[ Upstream commit a1cdec57e03a1352e92fbbe7974039dda4efcec0 ]
UDP sendmsg() can be lockless, this is causing all kinds
of data races.
This patch converts sk->sk_tskey to remove one of these races.

Whenever one of these functions pull all data from an skb in a frag_list,
use consume_skb() instead of kfree_skb() to avoid polluting drop

bpf: Do not try bpf_msg_push_data with len 0
commit 4a11678f683814df82fca9018d964771e02d7e6d upstream.
If bpf_msg_push_data() is called with len 0 (as it happens during
selftests/bpf/test_sockmap), we do not need to do anything and can
return early.
Calling bpf_msg_push_data() with len 0 previously lead to a wrong ENOMEM
error: we later called get_order(copy + len); if len was 0, copy + len
was also often 0 and get_order() returned some undefined value (at the
moment 52). alloc_pages() caught that and failed, but then bpf_msg_push_data()
returned ENOMEM. This was wrong because we are most probably not out of
memory and actually do not need any additional memory.

drop_monitor: fix data-race in dropmon_net_event / trace_napi_poll_hit
commit dcd54265c8bc14bd023815e36e2d5f9d66ee1fee upstream.
trace_napi_poll_hit() is reading stat->dev while another thread can write
on it from dropmon_net_event()
Use READ_ONCE()/WRITE_ONCE() here, RCU rules are properly enforced already,
we only have to take care of load/store tearing.

rtnetlink: make sure to refresh master_dev/m_ops in __rtnl_newlink()
commit c6f6f2444bdbe0079e41914a35081530d0409963 upstream.
While looking at one unrelated syzbot bug, I found the replay logic
in __rtnl_newlink() to potentially trigger use-after-free.
It is better to clear master_dev and m_ops inside the loop,
in case we have to replay it.

net-procfs: show net devices bound packet types
commit 1d10f8a1f40b965d449e8f2d5ed7b96a7c138b77 upstream.
After commit:7866a621043f ("dev: add per net_device packet type chains"),
we can not get packet types that are bound to a specified net device by
/proc/net/ptype, this patch fix the regression.
Run "tcpdump -i ens192 udp -nns0" Before and after apply this patch:
Before:
[root@localhost ~]# cat /proc/net/ptype
Type Device Function
0800 ip_rcv
0806 arp_rcv
86dd ipv6_rcv
After:
[root@localhost ~]# cat /proc/net/ptype
Type Device Function
ALL ens192 tpacket_rcv
0800 ip_rcv
0806 arp_rcv
86dd ipv6_rcv
v1 -> v2:
- fix the regression rather than adding new /proc API as
suggested by Stephen Hemminger.

net: fix information leakage in /proc/net/ptype
commit 47934e06b65637c88a762d9c98329ae6e3238888 upstream.
In one net namespace, after creating a packet socket without binding
it to a device, users in other net namespaces can observe the new
`packet_type` added by this packet socket by reading `/proc/net/ptype`
file. This is minor information leakage as packet socket is
namespace aware.
Add a net pointer in `packet_type` to keep the net namespace of
of corresponding packet socket. In `ptype_seq_show`, this net pointer
must be checked when it is not NULL.

commit 2a4d75bfe41232608f5596a6d1369f92ccb20817 upstream.
Don't forget to release the device in sock_timestamping_bind_phc() after
it was used to get the vclock indices.

netns: add schedule point in ops_exit_list()
commit 2836615aa22de55b8fca5e32fe1b27a67cda625e upstream.
When under stress, cleanup_net() can have to dismantle
netns in big numbers. ops_exit_list() currently calls
many helpers [1] that have no schedule point, and we can
end up with soft lockups, particularly on hosts
with many cpus.
Even for moderate amount of netns processed by cleanup_net()
this patch avoids latency spikes.
[1] Some of these helpers like fib_sync_up() and fib_sync_down_dev()
are very slow because net/ipv4/fib_semantics.c uses host-wide hash tables,
and ifindex is used as the only input of two hash functions.
ifindexes tend to be the same for all netns (lo.ifindex==1 per instance)
This will be fixed in a separate patch.

xdp: check prog type before updating BPF link
commit 382778edc8262b7535f00523e9eb22edba1b9816 upstream.
The bpf_xdp_link_update() function didn't check the program type before
updating the program, which made it possible to install any program type as
an XDP program, which is obviously not good. Syzbot managed to trigger this
by swapping in an LWT program on the XDP hook which would crash in a helper
call.
Fix this by adding a check and bailing out if the types don't match.

bpf: Do not WARN in bpf_warn_invalid_xdp_action()
[ Upstream commit 2cbad989033bff0256675c38f96f5faab852af4b ] The WARN_ONCE() in bpf_warn_invalid_xdp_action() can be triggered by any bugged program, and even attaching a correct program to a NIC not supporting the given action. The resulting splat, beyond polluting the logs, fouls automated tools: e.g. a syzkaller reproducers using an XDP program returning an unsupported action will never pass validation.

net/sched: flow_dissector: Fix matching on zone id for invalid conns
[ Upstream commit 3849595866166b23bf6a0cb9ff87e06423167f67 ]
If ct rejects a flow, it removes the conntrack info from the skb.
act_ct sets the post_ct variable so the dissector will see this case
as an +tracked +invalid state, but the zone id is lost with the
conntrack info.
To restore the zone id on such cases, set the last executed zone,
via the tc control block, when passing ct, and read it back in the
dissector if there is no ct info on the skb (invalid connection).

bpf, sockmap: Fix double bpf_prog_put on error case in map_link
[ Upstream commit 218d747a4142f281a256687bb513a135c905867b ]
sock_map_link() is called to update a sockmap entry with a sk. But, if the
sock_map_init_proto() call fails then we return an error to the map_update
op against the sockmap. In the error path though we need to cleanup psock
and dec the refcnt on any programs associated with the map, because we
refcnt them early in the update process to ensure they are pinned for the
psock. (This avoids a race where user deletes programs while also updating
the map with new socks.)
In current code we do the prog refcnt dec explicitely by calling
bpf_prog_put() when the program was found in the map. But, after commit
'38207a5e81230' in this error path we've already done the prog to psock
assignment so the programs have a reference from the psock as well. This
then causes the psock tear down logic, invoked by sk_psock_put() in the
error path, to similarly call bpf_prog_put on the programs there.
To be explicit this logic does the prog->psock assignment:
if (msg_*)
psock_set_prog(...)
Then the error path under the out_progs label does a similar check and
dec with:
if (msg_*)
bpf_prog_put(...)
And the teardown logic sk_psock_put() does ...
psock_set_prog(msg_*, NULL)
... triggering another bpf_prog_put(...). Then KASAN gives us this splat,
found by syzbot because we've created an inbalance between bpf_prog_inc and
bpf_prog_put calling put twice on the program.
BUG: KASAN: vmalloc-out-of-bounds in __bpf_prog_put kernel/bpf/syscall.c:1812 [inline]
BUG: KASAN: vmalloc-out-of-bounds in __bpf_prog_put kernel/bpf/syscall.c:1812 [inline] kernel/bpf/syscall.c:1829
BUG: KASAN: vmalloc-out-of-bounds in bpf_prog_put+0x8c/0x4f0 kernel/bpf/syscall.c:1829 kernel/bpf/syscall.c:1829
Read of size 8 at addr ffffc90000e76038 by task syz-executor020/3641
To fix clean up error path so it doesn't try to do the bpf_prog_put in the
error path once progs are assigned then it relies on the normal psock
tear down logic to do complete cleanup.
For completness we also cover the case whereh sk_psock_init_strp() fails,
but this is not expected because it indicates an incorrect socket type
and should be caught earlier.

commit 8bda81a4d400cf8a72e554012f0d8c45e07a3904 upstream.
lwtunnel_valid_encap_type_attr is used to validate encap attributes
within a multipath route. Add length validation checking to the type.
lwtunnel_valid_encap_type_attr is called converting attributes to
fib{6,}_config struct which means it is used before fib_get_nhs,
ip6_route_multipath_add, and ip6_route_multipath_del - other
locations that use rtnh_ok and then nla_get_u16 on RTA_ENCAP_TYPE
attribute.

net, neigh: clear whole pneigh_entry at alloc time
commit e195e9b5dee6459d8c8e6a314cc71a644a0537fd upstream.
Commit 2c611ad97a82 ("net, neigh: Extend neigh->flags to 32 bit
to allow for extensions") enables a new KMSAM warning [1]
I think the bug is actually older, because the following intruction
only occurred if ndm->ndm_flags had NTF_PROXY set.
pn->flags = ndm->ndm_flags;
Let's clear all pneigh_entry fields at alloc time.

bpf, sockmap: Re-evaluate proto ops when psock is removed from sockmap
commit c0d95d3380ee099d735e08618c0d599e72f6c8b0 upstream.
When a sock is added to a sock map we evaluate what proto op hooks need to
be used. However, when the program is removed from the sock map we have not
been evaluating if that changes the required program layout.
Before the patch listed in the 'fixes' tag this was not causing failures
because the base program set handles all cases. Specifically, the case with
a stream parser and the case with out a stream parser are both handled. With
the fix below we identified a race when running with a proto op that attempts
to read skbs off both the stream parser and the skb->receive_queue. Namely,
that a race existed where when the stream parser is empty checking the
skb->receive_queue from recvmsg at the precies moment when the parser is
paused and the receive_queue is not empty could result in skipping the stream
parser. This may break a RX policy depending on the parser to run.
The fix tag then loads a specific proto ops that resolved this race. But, we
missed removing that proto ops recv hook when the sock is removed from the
sockmap. The result is the stream parser is stopped so no more skbs will be
aggregated there, but the hook and BPF program continues to be attached on
the psock. User space will then get an EBUSY when trying to read the socket
because the recvmsg() handler is now waiting on a stopped stream parser.
To fix we rerun the proto ops init() function which will look at the new set
of progs attached to the psock and rest the proto ops hook to the correct
handlers. And in the above case where we remove the sock from the sock map
the RX prog will no longer be listed so the proto ops is removed.

devlink: fix netns refcount leak in devlink_nl_cmd_reload()
commit 4dbb0dad8e63fcd0b5a117c2861d2abe7ff5f186 upstream. While preparing my patch series adding netns refcount tracking, I spotted bugs in devlink_nl_cmd_reload() Some error paths forgot to release a refcount on a netns. To fix this, we can reduce the scope of get_net()/put_net() section around the call to devlink_reload(). Fixes: |

bpf, sockmap: Attach map progs to psock early for feature probes
commit 38207a5e81230d6ffbdd51e5fa5681be5116dcae upstream.
When a TCP socket is added to a sock map we look at the programs attached
to the map to determine what proto op hooks need to be changed. Before
the patch in the 'fixes' tag there were only two categories -- the empty
set of programs or a TX policy. In any case the base set handled the
receive case.
After the fix we have an optimized program for receive that closes a small,
but possible, race on receive. This program is loaded only when the map the
psock is being added to includes a RX policy. Otherwise, the race is not
possible so we don't need to handle the race condition.
In order for the call to sk_psock_init() to correctly evaluate the above
conditions all progs need to be set in the psock before the call. However,
in the current code this is not the case. We end up evaluating the
requirements on the old prog state. If your psock is attached to multiple
maps -- for example a tx map and rx map -- then the second update would pull
in the correct maps. But, the other pattern with a single rx enabled map
the correct receive hooks are not used. The result is the race fixed by the
patch in the fixes tag below may still be seen in this case.
To fix we simply set all psock->progs before doing the call into
sock_map_init(). With this the init() call gets the full list of programs
and chooses the correct proto ops on the first iteration instead of
requiring the second update to pull them in. This fixes the race case when
only a single map is used.

wireguard: device: reset peer src endpoint when netns exits
commit 20ae1d6aa159eb91a9bf09ff92ccaa94dbea92c2 upstream.
Each peer's endpoint contains a dst_cache entry that takes a reference
to another netdev. When the containing namespace exits, we take down the
socket and prevent future sockets from being created (by setting
creating_net to NULL), which removes that potential reference on the
netns. However, it doesn't release references to the netns that a netdev
cached in dst_cache might be taking, so the netns still might fail to
exit. Since the socket is gimped anyway, we can simply clear all the
dst_caches (by way of clearing the endpoint src), which will release all
references.
However, the current dst_cache_reset function only releases those
references lazily. But it turns out that all of our usages of
wg_socket_clear_peer_endpoint_src are called from contexts that are not
exactly high-speed or bottle-necked. For example, when there's
connection difficulty, or when userspace is reconfiguring the interface.
And in particular for this patch, when the netns is exiting. So for
those cases, it makes more sense to call dst_release immediately. For
that, we add a small helper function to dst_cache.
This patch also adds a test to netns.sh from Hangbin Liu to ensure this
doesn't regress.

ipv6: fix memory leak in fib6_rule_suppress
commit cdef485217d30382f3bf6448c54b4401648fe3f1 upstream. The kernel leaks memory when a `fib` rule is present in IPv6 nftables firewall rules and a suppress_prefix rule is present in the IPv6 routing rules (used by certain tools such as wg-quick). In such scenarios, every incoming packet will leak an allocation in `ip6_dst_cache` slab cache. After some hours of `bpftrace`-ing and source code reading, I tracked down the issue to |

sock: fix /proc/net/sockstat underflow in sk_clone_lock()
[ Upstream commit 938cca9e4109b30ee1d476904538225a825e54eb ]
sk_clone_lock() needs to call sock_inuse_add(1) before entering the
sk_free_unlock_clone() error path, for __sk_free() from sk_free() from
sk_free_unlock_clone() calls sock_inuse_add(-1).
