Lubomir Rintel 7c62b8dd5c net/ipv6: lower the level of "link is not ready" messages
This message gets logged far too often for how interesting is it.

Most distributions nowadays configure NetworkManager to use randomly
generated MAC addresses for Wi-Fi network scans. The interfaces end up
being periodically brought down for the address change. When they're
subsequently brought back up, the message is logged, eventually flooding
the log.

Perhaps the message is not all that helpful: it seems to be more
interesting to hear when the addrconf actually start, not when it does
not. Let's lower its level.

Yangbo Lu 5d9bf43357 net: dpaa2: improve PTP Kconfig option
Converted to use "imply" instead of "select" for PTP_1588_CLOCK
driver selecting. This could break the hard dependency between
the PTP clock subsystem and ethernet drivers.
This patch also set "default y" for dpaa2 ptp driver building to
provide user an available ptp clock in default.

David S. Miller 8fb18be93e Merge branch 'qed-Error-recovery-process'
Michal Kalderon says:

====================
qed*: Error recovery process

Parity errors might happen in the device's memories due to momentary bit
flips which are caused by radiation.
Errors that are not correctable initiate a process kill event, which blocks
the device access towards the host and the network, and a recovery process
is started in the management FW and in the driver.

This series adds the support of this process in the qed core module and in
the qede driver (patches 2 & 3).
Patch 1 in the series revises the load sequence, to avoid PCI errors that
might be observed during a recovery process.

Tomer Tayar 278396de78 qede: Error recovery process
This patch adds the error recovery process in the qede driver.
The process includes a partial/customized driver unload and load, which
allows it to look like a short suspend period to the kernel while
preserving the net devices' state.

Tomer Tayar c75860e48a qed: Add infrastructure for error detection and recovery
This patch adds the detection and handling of a parity error ("process kill
event"), including the update of the protocol drivers, and the prevention
of any HW access that will lead to device access towards the host while
recovery is in progress.
It also provides the means for the protocol drivers to trigger a recovery
process on their decision.

Tomer Tayar cfdb1b63ee qed: Revise load sequence to avoid PCI errors
Initiating final cleanup after an ungraceful driver unload can lead to bad
PCI accesses towards the host.
This patch revises the load sequence so final cleanup is sent while the
internal master enable is cleared, to prevent the host accesses, and clears
the internal error indications just before enabling the internal master
enable.

in6_dump_addrs() returns a positive 1 if there was nothing to dump.

Thomas Gleixner 56cb4e5034 net: sun: cassini: Cleanup license conflict
The recent addition of SPDX license identifiers to the files in
drivers/net/ethernet/sun created a licensing conflict.

The cassini driver files contain a proper license notice:

  * This program is free software; you can redistribute it and/or
  * modify it under the terms of the GNU General Public License as
  * published by the Free Software Foundation; either version 2 of the
  * License, or (at your option) any later version.

but the SPDX change added:

   SPDX-License-Identifier: GPL-2.0

So the file got tagged GPL v2 only while in fact it is licensed under GPL
v2 or later.

It's nice that people care about the SPDX tags, but they need to be more
careful about it. Not everything under (the) sun belongs to ...

Fix up the SPDX identifier and remove the boiler plate text as it is
redundant.

Ard Biesheuvel 2c88c742d0 gcc-plugins: arm_ssp_per_task_plugin: fix for GCC 9+
GCC 9 reworks the way the references to the stack canary are
emitted, to prevent the value from being spilled to the stack
before the final comparison in the epilogue, defeating the
purpose, given that the spill slot is under control of the
attacker that we are protecting ourselves from.

Since our canary value address is obtained without accessing
memory (as opposed to pre-v7 code that will obtain it from a
literal pool), it is unlikely (although not guaranteed) that
the compiler will spill the canary value in the same way, so
let's just disable this improvement when building with GCC9+.

Florian La Roche fbfaf85190 fix int_sqrt64() for very large numbers
If an input number x for int_sqrt64() has the highest bit set, then
fls64(x) is 64.  (1UL << 64) is an overflow and breaks the algorithm.

Subtracting 1 is a better guess for the initial value of m anyway and
that's what also done in int_sqrt() implicitly [*].

[*] Note how int_sqrt() uses __fls() with two underscores, which already
    returns the proper raw bit number.

    In contrast, int_sqrt64() used fls64(), and that returns bit numbers
    illogically starting at 1, because of error handling for the "no
    bits set" case. Will points out that he bug probably is due to a
    copy-and-paste error from the regular int_sqrt() case.

Will Deacon 6e693b3ffe x86: uaccess: Inhibit speculation past access_ok() in user_access_begin()
Commit 594cc251fd ("make 'user_access_begin()' do 'access_ok()'")
makes the access_ok() check part of the user_access_begin() preceding a
series of 'unsafe' accesses.  This has the desirable effect of ensuring
that all 'unsafe' accesses have been range-checked, without having to
pick through all of the callsites to verify whether the appropriate
checking has been made.

However, the consolidated range check does not inhibit speculation, so
it is still up to the caller to ensure that they are not susceptible to
any speculative side-channel attacks for user addresses that ultimately
fail the access_ok() check.

This is an oversight, so use __uaccess_begin_nospec() to ensure that
speculation is inhibited until the access_ok() check has passed.

The generated test constructs a packet with mac header, network
header, skb->data pointing to network header and skb->len 0.

Redirecting to a sit0 through __bpf_redirect_no_mac pulls the
mac length, even though skb->data already is at skb->network_header.
bpf_prog_test_run_skb has already pulled it as LWT_XMIT !is_l2.

Update the offset calculation to pull only if skb->data differs
from skb->network_header, which is not true in this case.

The test itself can be run only from commit 1cf1cae963 ("bpf:
introduce BPF_PROG_TEST_RUN command"), but the same type of packets
with skb at network header could already be built from lwt xmit hooks,
so this fix is more relevant to that commit.

Also set the mac header on redirect from LWT_XMIT, as even after this
change to __bpf_redirect_no_mac that field is expected to be set, but
is not yet in ip_finish_output2.

This is equivalent to just "\0". Nick pointed out that it is smarter to
use "" instead of "\0" because "" is used elsewhere in the kernel and
can be deduplicated at the linking stage.

Eli Britstein 25f2d0e779 net/mlx5e: Fix cb_ident duplicate in indirect block register
Previously the identifier used for indirect block callback registry
and for block rule cb registry (when done via indirect blocks) was the
pointer to the tunnel netdev we were interested in receiving updates on.
This worked fine if a single PF existed that registered one callback for
the tunnel netdev of interest. However, if multiple PFs are in place then
the 2nd PF tries to register with the same tunnel netdev identifier. This
leads to EEXIST errors and/or incorrect cb deletions.

Prevent this conflict by using the rpriv pointer as the identifier for
netdev indirect block cb registry, allowing each PF to register a unique
callback per tunnel netdev. For block cb registry, the same PF may
register multiple cbs to the same block if using TC shared blocks.
Instead of the rpriv, use the pointer to the allocated indr_priv data as
the identifier here. This means that there can be a unique block callback
for each PF/tunnel netdev combo.

Cong Wang e8c8b53cca net/mlx5e: Force CHECKSUM_UNNECESSARY for short ethernet frames
When an ethernet frame is padded to meet the minimum ethernet frame
size, the padding octets are not covered by the hardware checksum.
Fortunately the padding octets are usually zero's, which don't affect
checksum. However, we have a switch which pads non-zero octets, this
causes kernel hardware checksum fault repeatedly.

Prior to:
commit '88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE ...")'
skb checksum was forced to be CHECKSUM_NONE when padding is detected.
After it, we need to keep skb->csum updated, like what we do for RXFCS.
However, fixing up CHECKSUM_COMPLETE requires to verify and parse IP
headers, it is not worthy the effort as the packets are so small that
CHECKSUM_COMPLETE can't save anything.

Thomas Gleixner 64cf548126 tools: bpftool: Cleanup license mess
Precise and non-ambiguous license information is important. The recent
relicensing of the bpftools introduced a license conflict.

The files have now:

     SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause

and

     * This program is free software; you can redistribute it and/or
     * modify it under the terms of the GNU General Public License
     * as published by the Free Software Foundation; either version
     * 2 of the License, or (at your option) any later version

Amazingly about 20 people acked that change and neither they nor the
committer noticed. Oh well.

Digging deeper: The files were imported from the iproute2 repository with
the GPL V2 or later boiler plate text in commit b66e907cfe ("tools:
bpftool: copy JSON writer from iproute2 repository")

Looking at the iproute2 repository at

  git://git.kernel.org/pub/scm/network/iproute2/iproute2.git

the following commit is the equivivalent:

  commit d9d8c839 ("json_writer: add SPDX Identifier (GPL-2/BSD-2)")

That commit explicitly removes the boiler plate and relicenses the code
uner GPL-2.0-only and BSD-2-Clause. As Steven wrote the original code and
also the relicensing commit, it's assumed that the relicensing was intended
to do exaclty that. Just the kernel side update failed to remove the boiler
plate. Do so now.

Daniel Borkmann 9d5564ddcf bpf: fix inner map masking to prevent oob under speculation
During review I noticed that inner meta map setup for map in
map is buggy in that it does not propagate all needed data
from the reference map which the verifier is later accessing.

In particular one such case is index masking to prevent out of
bounds access under speculative execution due to missing the
map's unpriv_array/index_mask field propagation. Fix this such
that the verifier is generating the correct code for inlined
lookups in case of unpriviledged use.

Before patch (test_verifier's 'map in map access' dump):

  # bpftool prog dump xla id 3
     0: (62) *(u32 *)(r10 -4) = 0
     1: (bf) r2 = r10
     2: (07) r2 += -4
     3: (18) r1 = map[id:4]
     5: (07) r1 += 272                |
     6: (61) r0 = *(u32 *)(r2 +0)     |
     7: (35) if r0 >= 0x1 goto pc+6   | Inlined map in map lookup
     8: (54) (u32) r0 &= (u32) 0      | with index masking for
     9: (67) r0 <<= 3                 | map->unpriv_array.
    10: (0f) r0 += r1                 |
    11: (79) r0 = *(u64 *)(r0 +0)     |
    12: (15) if r0 == 0x0 goto pc+1   |

    16: (62) *(u32 *)(r10 -4) = 0
    17: (bf) r2 = r10
    18: (07) r2 += -4
    19: (bf) r1 = r0
    20: (07) r1 += 272                |
    21: (61) r0 = *(u32 *)(r2 +0)     | Index masking missing (!)
    22: (35) if r0 >= 0x1 goto pc+3   | for inner map despite

    27: (b7) r0 = 0
    28: (95) exit

After patch:

  # bpftool prog dump xla id 1

====================
mlxsw: Various fixes

This patchset contains small fixes in mlxsw and one fix in the bridge
driver.

Patches #1-#4 perform small adjustments in PCI and FID code following
recent tests that were performed on the Spectrum-2 ASIC.

Patch #5 fixes the bridge driver to mark FDB entries that were added by
user as such. Otherwise, these entries will be ignored by underlying
switch drivers.

Patch #6 fixes a long standing issue in mlxsw where the driver
incorrectly programmed static FDB entries as both static and sticky.

Patches #7-#8 add test cases for above mentioned bugs.

Ido Schimmel 64254a2054 mlxsw: spectrum_switchdev: Do not treat static FDB entries as sticky
The driver currently treats static FDB entries as both static and
sticky. This is incorrect and prevents such entries from being roamed to
a different port via learning.

Fix this by configuring static entries with ageing disabled and roaming
enabled.

In net-next we can add proper support for the newly introduced 'sticky'
flag.

Ido Schimmel 710ae72877 net: bridge: Mark FDB entries that were added by user as such
Externally learned entries can be added by a user or by a switch driver
that is notifying the bridge driver about entries that were learned in
hardware.

In the first case, the entries are not marked with the 'added_by_user'
flag, which causes switch drivers to ignore them and not offload them.

The 'added_by_user' flag can be set on externally learned FDB entries
based on the 'swdev_notify' parameter in br_fdb_external_learn_add(),
which effectively means if the created / updated FDB entry was added by
a user or not.
