Here is another set of reviewed patches that adds SPDX tags to different
kernel files, based on a set of rules that are being used to parse the
comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review and
analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on the
patches are reviewers.

TCP zerocopy takes a uarg reference for every skb, plus one for the
tcp_sendmsg_locked datapath temporarily, to avoid reaching refcnt zero
as it builds, sends and frees skbs inside its inner loop.
UDP and RAW zerocopy do not send inside the inner loop so do not need
the extra sock_zerocopy_get + sock_zerocopy_put pair. Commit
52900d22288ed ("udp: elide zerocopy operation in hot path") introduced
extra_uref to pass the initial reference taken in sock_zerocopy_alloc
to the first generated skb.
But, sock_zerocopy_realloc takes this extra reference at the start of
every call. With MSG_MORE, no new skb may be generated to attach the
extra_uref to, so refcnt is incorrectly 2 with only one skb.
Do not take the extra ref if uarg && !tcp, which implies MSG_MORE.
Update extra_uref accordingly.
This conditional assignment triggers a false positive may be used
uninitialized warning, so have to initialize extra_uref at define.

When parsing an ethtool flow spec to build a flow_rule, the code checks
if both the vlan etype and the vlan tci are specified by the user to add
a FLOW_DISSECTOR_KEY_VLAN match.
However, when the user only specified a vlan etype or a vlan tci, this
check silently ignores these parameters.
For example, the following rule :
ethtool -N eth0 flow-type udp4 vlan 0x0010 action -1 loc 0
will result in no error being issued, but the equivalent rule will be
created and passed to the NIC driver :
ethtool -N eth0 flow-type udp4 action -1 loc 0
In the end, neither the NIC driver using the rule nor the end user have
a way to know that these keys were dropped along the way, or that
incorrect parameters were entered.
This kind of check should be left to either the driver, or the ethtool
flow spec layer.
This commit makes so that ethtool parameters are forwarded as-is to the
NIC driver.
Since none of the users of ethtool_rx_flow_rule_create are using the
VLAN dissector, I don't think this qualifies as a regression.

If a network driver provides to napi_gro_frags() an
skb with a page fragment of exactly 14 bytes, the call
to gro_pull_from_frag0() will 'consume' the fragment
by calling skb_frag_unref(skb, 0), and the page might
be freed and reused.
Reading eth->h_proto at the end of napi_frags_skb() might
read mangled data, or crash under specific debugging features.

Tools like tcpdump need to be able to decode the significance of fake
VLAN headers that DSA uses to separate switch ports.
But currently these have no global significance - they are simply an
ordered list of DSA_MAX_SWITCHES x DSA_MAX_PORTS numbers ending at 4095.
The reason why this is submitted as a fix is that the existing mapping
of VIDs should not enter into a stable kernel, so we can pretend that
only the new format exists. This way tcpdump won't need to try to make
something out of the VLAN tags on 5.2 kernels.

The 802.1Q tagging performs an unbalanced setup in terms of RX VIDs on
the CPU port. For the ingress path of a 802.1Q switch to work, the RX
VID of a port needs to be seen as tagged egress on the CPU port.
While configuring the other front-panel ports to be part of this VID,
for bridge scenarios, the untagged flag is applied even on the CPU port
in dsa_switch_vlan_add. This happens because DSA applies the same flags
on the CPU port as on the (bridge-controlled) slave ports, and the
effect in this case is that the CPU port tagged settings get deleted.
Instead of fixing DSA by introducing a way to control VLAN flags on the
CPU port (and hence stop inheriting from the slave ports) - a hard,
perhaps intractable problem - avoid this situation by moving the setup
part of the RX VID on the CPU port after all the other front-panel ports
have been added to the VID.

The TCP option parsing routines in tcp_parse_options function could
read one byte out of the buffer of the TCP options.
1 while (length > 0) {
2 int opcode = *ptr++;
3 int opsize;
4
5 switch (opcode) {
6 case TCPOPT_EOL:
7 return;
8 case TCPOPT_NOP: /* Ref: RFC 793 section 3.1 */
9 length--;
10 continue;
11 default:
12 opsize = *ptr++; //out of bound access
If length = 1, then there is an access in line2.
And another access is occurred in line 12.
This would lead to out-of-bound access.
Therefore, in the patch we check that the available data length is
larger enough to pase both TCP option code and size.

When tls_sw_recvmsg() partially copies a record it pops that
record from ctx->recv_pkt and places it on rx_list.
Next iteration of tls_sw_recvmsg() reads from rx_list via
process_rx_list() before it enters the decryption loop.
If there is no more records to be read tls_wait_data()
will put the process on the wait queue and got to sleep.
This is incorrect, because some data was already copied
in process_rx_list().
In case of RPC connections process may never get woken up,
because peer also simply blocks in read().
I think this may also fix a similar issue when BPF is at
play, because after __tcp_bpf_recvmsg() returns some data
we subtract it from len and use continue to restart the
loop, but len could have just reached 0, so again we'd
sleep unnecessarily. That's added by:

If some of the data came from the previous record, i.e. from
the rx_list it had already been decrypted, so it's not counted
towards the "decrypted" variable, but the "copied" variable.
Take that into account when checking lowat.
When calculating lowat target we need to pass the original len.
E.g. if lowat is at 80, len is 100 and we had 30 bytes on rx_list
target would currently be incorrectly calculated as 70, even though
we only need 50 more bytes to make up the 80.

Function tcf_action_dump() relies on tc_action->order field when starting
nested nla to send action data to userspace. This approach breaks in
several cases:
- When multiple filters point to same shared action, tc_action->order field
is overwritten each time it is attached to filter. This causes filter
dump to output action with incorrect attribute for all filters that have
the action in different position (different order) from the last set
tc_action->order value.
- When action data is displayed using tc action API (RTM_GETACTION), action
order is overwritten by tca_action_gd() according to its position in
resulting array of nl attributes, which will break filter dump for all
filters attached to that shared action that expect it to have different
order value.
Don't rely on tc_action->order when dumping actions. Set nla according to
action position in resulting array of actions instead.

TLS offload drivers shouldn't (and currently don't) block
the TLS offload feature changes based on whether there are
active offloaded connections or not.
This seems to be a good idea, because we want the admin to
be able to disable the TLS offload at any time, and there
is no clean way of disabling it for active connections
(TX side is quite problematic). So if features are cleared
existing connections will stay offloaded until they close,
and new connections will not attempt offload to a given
device.
However, the offload state removal handling is currently
broken if feature flags get cleared while there are
active TLS offloads.
RX side will completely bail from cleanup, even on normal
remove path, leaving device state dangling, potentially
causing issues when the 5-tuple is reused. It will also
fail to release the netdev reference.
Remove the RX-side warning message, in next release cycle
it should be printed when features are disabled, rather
than when connection dies, but for that we need a more
efficient method of finding connection of a given netdev
(a'la BPF offload code).

When netdev with active kTLS sockets in unregistered
notifier callback walks the offloaded sockets and
cleans up offload state. RX data may still be processed,
however, and if resync was requested prior to device
removal we would hit a NULL pointer dereference on
ctx->netdev use.
Make sure resync is under the device offload lock
and NULL-check the netdev pointer.
This should be safe, because the pointer is set to
NULL either in the netdev notifier (under said lock)
or when socket is completely dead and no resync can
happen.
The other access to ctx->netdev in tls_validate_xmit_skb()
does not dereference the pointer, it just checks it against
other device pointer, so it should be pretty safe (perhaps
we can add a READ_ONCE/WRITE_ONCE there, if paranoid).
