06ab1e63ec net: fix proc_fs init handling in af_packet and tls
[ Upstream commit a268e0f245 ]

proc_fs was used, in af_packet, without a surrounding #ifdef,
although there is no hard dependency on proc_fs.
That caused the initialization of the af_packet module to fail
when CONFIG_PROC_FS=n.

Specifically, proc_create_net() was used in af_packet.c,
and when it fails, packet_net_init() returns -ENOMEM.
It will always fail when the kernel is compiled without proc_fs,
because, proc_create_net() for example always returns NULL.

The calling order that starts in af_packet.c is as follows:
packet_init()
register_pernet_subsys()
register_pernet_operations()
__register_pernet_operations()
ops_init()
ops->init() (packet_net_ops.init=packet_net_init())
proc_create_net()

It worked in the past because register_pernet_subsys()'s return value
wasn't checked before this Commit 36096f2f4f ("packet: Fix error path in
packet_init.").
It always returned an error, but was not checked before, so everything
was working even when CONFIG_PROC_FS=n.

The fix here is simply to add the necessary #ifdef.

This also fixes a similar error in tls_proc.c, that was found by Jakub
Kicinski.

2bce178c25 net: openvswitch: fix TTL decrement exception action execution
[ Upstream commit 09d6217254 ]

Currently, the exception actions are not processed correctly as the wrong
dataset is passed. This change fixes this, including the misleading
comment.

In addition, a check was added to make sure we work on an IPv4 packet,
and not just assume if it's not IPv6 it's IPv4.

This was all tested using OVS with patch,
https://patchwork.ozlabs.org/project/openvswitch/list/?series=21639,
applied and sending packets with a TTL of 1 (and 0), both with IPv4
and IPv6.

69e9fd9de1 vsock: fix locking in vsock_shutdown()
commit 1c5fae9c9a upstream.

In vsock_shutdown() we touched some socket fields without holding the
socket lock, such as 'state' and 'sk_flags'.

Also, after the introduction of multi-transport, we are accessing
'vsk->transport' in vsock_send_shutdown() without holding the lock
and this call can be made while the connection is in progress, so
the transport can change in the meantime.

To avoid issues, we hold the socket lock when we enter in
vsock_shutdown() and release it when we leave.

Among the transports that implement the 'shutdown' callback, only
hyperv_transport acquired the lock. Since the caller now holds it,
we no longer take it.

55ad30cb7f bridge: mrp: Fix the usage of br_mrp_port_switchdev_set_state
commit b2bdba1cbc upstream.

The function br_mrp_port_switchdev_set_state was called both with MRP
port state and STP port state, which is an issue because they don't
match exactly.

Therefore, update the function to be used only with STP port state and
use the id SWITCHDEV_ATTR_ID_PORT_STP_STATE.

The choice of using STP over MRP is that the drivers already implement
SWITCHDEV_ATTR_ID_PORT_STP_STATE and already in SW we update the port
STP state.

commit 3d0bc44d39 upstream.

A possible locking issue in vsock_connect_timeout() was recognized by
Eric Dumazet which might cause a null pointer dereference in
vsock_transport_cancel_pkt(). This patch assures that
vsock_transport_cancel_pkt() will be called within the lock, so a race
condition won't occur which could result in vsk->transport to be set to NULL.

c901381341 net: fix iteration for sctp transport seq_files
commit af8085f3a4 upstream.

The sctp transport seq_file iterators take a reference to the transport
in the ->start and ->next functions and releases the reference in the
->show function.  The preferred handling for such resources is to
release them in the subsequent ->next or ->stop function call.

Since Commit 1f4aace60b ("fs/seq_file.c: simplify seq_file iteration
code and interface") there is no guarantee that ->show will be called
after ->next, so this function can now leak references.

So move the sctp_transport_put() call to ->next and ->stop.

Commit c80794323e ("net: Fix packet reordering caused by GRO and

latencies in common workloads.

Before the patch, GRO packets were immediately passed to
upper stacks.

After the patch, we can accumulate quite a lot of GRO
packets (depdending on NAPI budget).

My fix is counting in napi->rx_count number of segments
instead of number of logical packets.

46a831d1cc udp: fix skb_copy_and_csum_datagram with odd segment sizes
commit 52cbd23a11 upstream.

When iteratively computing a checksum with csum_block_add, track the
offset "pos" to correctly rotate in csum_block_add when offset is odd.

The open coded implementation of skb_copy_and_csum_datagram did this.
With the switch to __skb_datagram_iter calling csum_and_copy_to_iter,
pos was reinitialized to 0 on each call.

Bring back the pos by passing it along with the csum to the callback.

Changes v1->v2
  - pass csum value, instead of csump pointer (Alexander Duyck)

24f5544f76 rxrpc: Fix clearance of Tx/Rx ring when releasing a call
commit 7b5eab57ca upstream.

At the end of rxrpc_release_call(), rxrpc_cleanup_ring() is called to clear
the Rx/Tx skbuff ring, but this doesn't lock the ring whilst it's accessing
it.  Unfortunately, rxrpc_resend() might be trying to retransmit a packet
concurrently with this - and whilst it does lock the ring, this isn't
protection against rxrpc_cleanup_call().

Fix this by removing the call to rxrpc_cleanup_ring() from
rxrpc_release_call().  rxrpc_cleanup_ring() will be called again anyway
from rxrpc_cleanup_call().  The earlier call is just an optimisation to
recycle skbuffs more quickly.

Alternative solutions include rxrpc_release_call() could try to cancel the
work item or wait for it to complete or rxrpc_cleanup_ring() could lock
when accessing the ring (which would require a bh lock).

This can produce a report like the following:

The origin skip check needs to re-test the zone. Else, we might skip
a colliding tuple in the reply direction.

This only occurs when using 'directional zones' where origin tuples
reside in different zones but the reply tuples share the same zone.

This causes the new conntrack entry to be dropped at confirmation time
because NAT clash resolution was elided.

[ Upstream commit 8d6bca156e ]

When updating the tcp or udp header checksum on port nat the function
inet_proto_csum_replace2 with the last parameter pseudohdr as true.
This leads to an error in the case that GRO is used and packets are
split up in GSO. The tcp or udp checksum of all packets is incorrect.

The error is probably masked due to the fact the most network driver
implement tcp/udp checksum offloading. It also only happens when GRO is
applied and not on single packets.

The error is most visible when using a pppoe connection which is not
triggering the tcp/udp checksum offload.

3ade81db49 ath9k: fix build error with LEDS_CLASS=m

When CONFIG_ATH9K is built-in but LED support is in a loadable
module, both ath9k drivers fails to link:

x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_deinit_leds':
gpio.c:(.text+0x36): undefined reference to `led_classdev_unregister'

gpio.c:(.text+0x179): undefined reference to `led_classdev_register_ext'

The problem is that the 'imply' keyword does not enforce any dependency
but is only a weak hint to Kconfig to enable another symbol from a
defconfig file.

Change imply to a 'depends on LEDS_CLASS' that prevents the incorrect
configuration but still allows building the driver without LED support.

The 'select MAC80211_LEDS' is now ensures that the LED support is
actually used if it is present, and the added Kconfig dependency
on MAC80211_LEDS ensures that it cannot be enabled manually when it
has no effect.

518416a75c SUNRPC: Handle 0 length opaque XDR object data properly
[ Upstream commit e4a7d1f770 ]

When handling an auth_gss downcall, it's possible to get 0-length
opaque object for the acceptor.  In the case of a 0-length XDR
object, make sure simple_get_netobj() fills in dest->data = NULL,
and does not continue to kmemdup() which will set
dest->data = ZERO_SIZE_PTR for the acceptor.

The trace event code can handle NULL but not ZERO_SIZE_PTR for a
string, and so without this patch the rpcgss_context trace event
will crash the kernel as follows:

Remove duplicated helper functions to parse opaque XDR objects

In the new file carry the license and copyright from the source file
net/sunrpc/auth_gss/auth_gss.c.  Finally, update the comment inside
include/linux/sunrpc/xdr.h since lockd is not the only user of
struct xdr_netobj.

1c19d6ae58 af_key: relax availability checks for skb size calculation
[ Upstream commit afbc293add ]

xfrm_probe_algs() probes kernel crypto modules and changes the
availability of struct xfrm_algo_desc. But there is a small window
where ealg->available and aalg->available get changed between
count_ah_combs()/count_esp_combs() and dump_ah_combs()/dump_esp_combs(),
in this case we may allocate a smaller skb but later put a larger
amount of data and trigger the panic in skb_put().

Fix this by relaxing the checks when counting the size, that is,
skipping the test of ->available. We may waste some memory for a few
of sizeof(struct sadb_comb), but it is still much better than a panic.

3d6df63a5c udp: ipv4: manipulate network header of NATed UDP GRO fraglist
commit c3df39ac9b upstream.

UDP/IP header of UDP GROed frag_skbs are not updated even after NAT
forwarding. Only the header of head_skb from ip_finish_output_gso ->
skb_gso_segment is updated but following frag_skbs are not updated.

A call path skb_mac_gso_segment -> inet_gso_segment ->
udp4_ufo_fragment -> __udp_gso_segment -> __udp_gso_segment_list
does not try to update UDP/IP header of the segment list but copy
only the MAC header.

Update port, addr and check of each skb of the segment list in
__udp_gso_segment_list. It covers both SNAT and DNAT.

f2b30f9f08 net: ip_tunnel: fix mtu calculation
commit 28e104d002 upstream.

dev->hard_header_len for tunnel interface is set only when header_ops
are set too and already contains full overhead of any tunnel encapsulation.
That's why there is not need to use this overhead twice in mtu calc.

6e4583ad6d neighbour: Prevent a dead entry from updating gc_list
commit eb4e8fac00 upstream.

Following race condition was detected:
<CPU A, t0> - neigh_flush_dev() is under execution and calls
neigh_mark_dead(n) marking the neighbour entry 'n' as dead.

<CPU B, t1> - Executing: __netif_receive_skb() ->
__netif_receive_skb_core() -> arp_rcv() -> arp_process().arp_process()
calls __neigh_lookup() which takes a reference on neighbour entry 'n'.

<CPU A, t2> - Moves further along neigh_flush_dev() and calls
neigh_cleanup_and_release(n), but since reference count increased in t2,
'n' couldn't be destroyed.

<CPU B, t3> - Moves further along, arp_process() and calls
neigh_update()-> __neigh_update() -> neigh_update_gc_list(), which adds
the neighbour entry back in gc_list(neigh_mark_dead(), removed it
earlier in t0 from gc_list)

<CPU B, t4> - arp_process() finally calls neigh_release(n), destroying
the neighbour entry.

This leads to 'n' still being part of gc_list, but the actual
neighbour structure has been freed.

The situation can be prevented from happening if we disallow a dead
entry to have any possibility of updating gc_list. This is what the
patch intends to achieve.

dec629e972 net: lapb: Copy the skb before sending a packet
[ Upstream commit 88c7a9fd9b ]

When sending a packet, we will prepend it with an LAPB header.
This modifies the shared parts of a cloned skb, so we should copy the
skb rather than just clone it, before we prepend the header.

In "Documentation/networking/driver.rst" (the 2nd point), it states
that drivers shouldn't modify the shared parts of a cloned skb when
transmitting.

The "dev_queue_xmit_nit" function in "net/core/dev.c", which is called
when an skb is being sent, clones the skb and sents the clone to
AF_PACKET sockets. Because the LAPB drivers first remove a 1-byte
pseudo-header before handing over the skb to us, if we don't copy the
skb before prepending the LAPB header, the first byte of the packets
received on AF_PACKET sockets can be corrupted.

8e081627f3 SUNRPC: Fix NFS READs that start at non-page-aligned offsets
[ Upstream commit bad4c6eb5e ]

Anj Duvnjak reports that the Kodi.tv NFS client is not able to read
video files from a v5.10.11 Linux NFS server.

The new sendpage-based TCP sendto logic was not attentive to non-
zero page_base values. nfsd_splice_read() sets that field when a
READ payload starts in the middle of a page.

The Linux NFS client rarely emits an NFS READ that is not page-
aligned. All of my testing so far has been with Linux clients, so I
missed this one.

e5ed4e08d8 rxrpc: Fix deadlock around release of dst cached on udp tunnel
[ Upstream commit 5399d52233 ]

AF_RXRPC sockets use UDP ports in encap mode.  This causes socket and dst
from an incoming packet to get stolen and attached to the UDP socket from
whence it is leaked when that socket is closed.

When a network namespace is removed, the wait for dst records to be cleaned
up happens before the cleanup of the rxrpc and UDP socket, meaning that the
wait never finishes.

Fix this by moving the rxrpc (and, by dependence, the afs) private
per-network namespace registrations to the device group rather than subsys
group.  This allows cached rxrpc local endpoints to be cleared and their
UDP sockets closed before we try waiting for the dst records.

The symptom is that lines looking like the following:

	unregister_netdevice: waiting for lo to become free

get emitted at regular intervals after running something like the
referenced syzbot test.

Thanks to Vadim for tracking this down and work out the fix.

8a4b8ea595 ANDROID: net: introduce ip_local_unbindable_ports sysctl
and associated inet_is_local_unbindable_port() helper function:
use it to make explicitly binding to an unbindable port return
-EPERM 'Operation not permitted'.

Autobind doesn't honour this new sysctl since:
  (a) you can simply set both if that's the behaviour you desire
  (b) there could be a use for preventing explicit while allowing auto
  (c) it's faster in the relatively critical path of doing port selection
      during connect() to only check one bitmap instead of both

Various ports may have special use cases which are not suitable for
use by general userspace applications. Currently, ports specified in
ip_local_reserved_ports sysctl will not be returned only in case of
automatic port assignment, but nothing prevents you from explicitly
binding to them - even from an entirely unprivileged process.

In certain cases it is desirable to prevent the host from assigning the
ports even in case of explicit binds, even from superuser processes.

Example use cases might be:
 - a port being stolen by the nic for remote serial console, remote
   power management or some other sort of debugging functionality
   (crash collection, gdb, direct access to some other microcontroller
   on the nic or motherboard, remote management of the nic itself).
 - a transparent proxy where packets are being redirected: in case
   a socket matches this connection, packets from this application
   would be incorrectly sent to one of the endpoints.

Initially I wanted to solve this problem via the simple one line:

static inline bool inet_port_requires_bind_service(struct net *net, unsigned short port) {
-       return port < net->ipv4.sysctl_ip_prot_sock;
+       return port < net->ipv4.sysctl_ip_prot_sock || inet_is_local_reserved_port(net, port);
}

However, this doesn't work for two reasons:
  (a) it changes userspace visible behaviour of the existing local
      reserved ports sysctl, and there appears to be enough documentation
      on the internet talking about setting it to make this a bad idea
  (b) it doesn't prevent privileged apps from using these ports,
      CAP_BIND_SERVICE is relatively likely to be available to, for example,
      a recursive DNS server so it can listed on port 53, which also needs
      to do src port randomization for outgoing queries due to security
      reasons (and it thus does manual port binding).

If we *know* that certain ports are simply unusable, then it's better
nothing even gets the opportunity to try to use them.  This way we at
least get a quick failure, instead of some sort of timeout (or possibly
even corruption of the data stream of the non-kernel based use case).

Test:
  vm:~# cat /proc/sys/net/ipv4/ip_local_unbindable_ports

  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0); s.bind(("::", 3967))'
  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM, 0); s.bind(("::", 3967))'
  vm:~# echo 3967 > /proc/sys/net/ipv4/ip_local_unbindable_ports
  vm:~# cat /proc/sys/net/ipv4/ip_local_unbindable_ports
  3967
  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0); s.bind(("::", 3967))'
  socket.error: (1, 'Operation not permitted')
  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM, 0); s.bind(("::", 3967))'
  socket.error: (1, 'Operation not permitted')
