To avoid a direct dependency with tc actions from netfilter, wrap the
redirect bits around CONFIG_NET_REDIRECT and move helpers to
include/linux/skbuff.h. Turn on this toggle from the ifb driver, the
only existing client of these bits in the tree.
This patch adds skb_set_redirected() that sets on the redirected bit
on the skbuff, it specifies if the packet was redirect from ingress
and resets the timestamp (timestamp reset was originally missing in the
netfilter bugfix).

Currently ENA only provides the PCI remove() handler, used during rmmod
for example. This is not called on shutdown/kexec path; we are potentially
creating a failure scenario on kexec:
(a) Kexec is triggered, no shutdown() / remove() handler is called for ENA;
instead pci_device_shutdown() clears the master bit of the PCI device,
stopping all DMA transactions;
(b) Kexec reboot happens and the device gets enabled again, likely having
its FW with that DMA transaction buffered; then it may trigger the (now
invalid) memory operation in the new kernel, corrupting kernel memory area.
This patch aims to prevent this, by implementing a shutdown() handler
quite similar to the remove() one - the difference being the handling
of the netdev, which is unregistered on remove(), but following the
convention observed in other drivers, it's only detached on shutdown().
This prevents an odd issue in AWS Nitro instances, in which after the 2nd
kexec the next one will fail with an initrd corruption, caused by a wild
DMA write to invalid kernel memory. The lspci output for the adapter
present in my instance is:
00:05.0 Ethernet controller [0200]: Amazon.com, Inc. Elastic Network
Adapter (ENA) [1d0f:ec20]

Pull zonefs fix from Damien Le Moal:
"A single fix from me to correctly handle the size of read-only zone
files"
* tag 'zonefs-5.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs:
zonfs: Fix handling of read-only zones
|
|
The write pointer of zones in the read-only consition is defined as
invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not
possible to determine the correct size of a read-only zone file on
mount. Fix this by handling read-only zones in the same manner as
offline zones by disabling all accesses to the zone (read and write)
and initializing the inode size of the read-only zone to 0).
For zones found to be in the read-only condition at runtime, only
disable write access to the zone and keep the size of the zone file to
its last updated value to allow the user to recover previously written
data.
Also fix zonefs documentation file to reflect this change.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) A new selftest for nf_queue, from Florian Westphal. This test
covers two recent fixes: 07f8e4d0fddb ("tcp: also NULL skb->dev
when copy was needed") and b738a185beaa ("tcp: ensure skb->dev is
NULL before leaving TCP stack").
2) The fwd action breaks with ifb. For safety in next extensions,
make sure the fwd action only runs from ingress until it is extended
to be used from a different hook.
3) The pipapo set type now reports EEXIST in case of subrange overlaps.
Update the rbtree set to validate range overlaps, so far this
validation is only done only from userspace. From Stefano Brivio.

Not only did this wheel did not need reinventing, but there is also
an issue with it: It doesn't remove the VLAN header in a way that
preserves the L2 payload checksum when that is being provided by the DSA
master hw. It should recalculate checksum both for the push, before
removing the header, and for the pull afterwards. But the current
implementation is quite dizzying, with pulls followed immediately
afterwards by pushes, the memmove is done before the push, etc. This
makes a DSA master with RX checksumming offload to print stack traces
with the infamous 'hw csum failure' message.
So remove the dsa_8021q_remove_header function and replace it with
something that actually works with inet checksumming.

Currently the software CBS does not consider the packet sending time
when depleting the credits. It caused the throughput to be
Idleslope[kbps] * (Port transmit rate[kbps] / |Sendslope[kbps]|) where
Idleslope * (Port transmit rate / (Idleslope + |Sendslope|)) = Idleslope
is expected. In order to fix the issue above, this patch takes the time
when the packet sending completes into account by moving the anchor time
variable "last" ahead to the send completion time upon transmission and
adding wait when the next dequeue request comes before the send
completion time of the previous packet.
changelog:
V2->V3:
- remove unnecessary whitespace cleanup
- add the checks if port_rate is 0 before division
V1->V2:
- combine variable "send_completed" into "last"
- add the comment for estimate of the packet sending

For non-fatal syndromes like LOCAL_LENGTH_ERR, recovery shouldn't be
triggered. In these scenarios, the RQ is not actually in ERR state.
This misleads the recovery flow which assumes that the RQ is really in

state.

In striding RQ mode, the buffers of an RX WQE are first
prepared and posted to the HW using a UMR WQEs via the ICOSQ.
We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not
in error state, hence:
- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

Add a test case to check nf queue infrastructure.
Could be extended in the future to also cover serialization of
conntrack, uid and secctx attributes in nfqueue.
For now, this checks that 'queue bypass' works, that a queue rule with
no bypass option blocks traffic and that userspace receives the expected
number of packets.
For this we add two queues and hook all of
prerouting/input/forward/output/postrouting.
Packets get queued twice with a dummy base chain in between:
This passes with current nf tree, but reverting
commit 946c0d8e6ed4 ("netfilter: nf_queue: fix reinject verdict handling")
makes this trip (it processes 30 instead of expected 20 packets).
v2: update config file with queue and other options missing/needed for
other tests.
v3: also test with tcp, this reveals problem with commit
28f8bfd1ac94 ("netfilter: Support iif matches in POSTROUTING"), due to
skb->dev pointing at another skb in the retransmit rbtree (skb->dev
aliases to rbnode child).

...and return -ENOTEMPTY to the front-end in this case, instead of
proceeding. Currently, nft takes care of checking for these cases
and not sending them to the kernel, but if we drop the set_overlap()
call in nft we can end up in situations like:
# nft add table t
# nft add set t s '{ type inet_service ; flags interval ; }'
# nft add element t s '{ 1 - 5 }'
# nft add element t s '{ 6 - 10 }'
# nft add element t s '{ 4 - 7 }'
# nft list set t s
table ip t {
set s {
type inet_service
flags interval
elements = { 1-3, 4-5, 6-7 }
}
}
This change has the primary purpose of making the behaviour
consistent with nft_set_pipapo, but is also functional to avoid
inconsistent behaviour if userspace sends overlapping elements for
any reason.
v2: When we meet the same key data in the tree, as start element while

insertion
Currently, the -EEXIST return code of ->insert() callbacks is ambiguous: it
might indicate that a given element (including intervals) already exists as
such, or that the new element would clash with existing ones.
If identical elements already exist, the front-end is ignoring this without
returning error, in case NLM_F_EXCL is not set. However, if the new element
can't be inserted due an overlap, we should report this to the user.
To this purpose, allow set back-ends to return -ENOTEMPTY on collision with
existing elements, translate that to -EEXIST, and return that to userspace,
no matter if NLM_F_EXCL was set.

5 bug fix patches covering an indexing bug for priority counters, memory
leak when retrieving DCB ETS settings, error path return code, proper
disabling of PCI before freeing context memory, and proper ring accounting
in error path.
Please also apply these to -stable. Thanks.

If ring counts are not reset when ring reservation fails,
bnxt_init_dflt_ring_mode() will not be called again to reinitialise
IRQs when open() is called and results in system crash as napi will
also be not initialised. This patch fixes it by resetting the ring
counts.

Other shutdown code paths will always disable PCI first to shutdown DMA
before freeing context memory. Do the same sequence in the error path
of probe to be safe and consistent.

The current code ignores the return value from
bnxt_hwrm_func_backing_store_cfg(), causing the driver to proceed in
the init path even when this vital firmware call has failed. Fix it
by propagating the error code to the caller.

The allocated ieee_ets structure goes out of scope without being freed,
leaking memory. Appropriate result codes should be returned so that
callers do not rely on invalid data passed by reference.
Also cache the ETS config retrieved from the device so that it doesn't
need to be freed. The balance of the code was clearly written with the
intent of having the results of querying the hardware cached in the
device structure. The commensurate store was evidently missed though.

There is an indexing bug in determining these ethtool priority
counters. Instead of using the queue ID to index, we need to
normalize by modulo 10 to get the index. This index is then used
to obtain the proper CoS queue counter. Rename bp->pri2cos to
bp->pri2cos_idx to make this more clear.

Only attach macsec to ethernet devices.
Syzbot was able to trigger a KMSAN warning in macsec_handle_frame
by attaching to a phonet device.
Macvlan has a similar check in macvlan_port_create.

Unlike NL_SET_ERR_* macros, nl_set_extack_cookie_u64() and
nl_set_extack_cookie_u32() helpers do not check extack argument for null
and neither do their callers, as syzbot recently discovered for
ethnl_parse_header().
Instead of fixing the callers and leaving the trap in place, add check of
null extack to both helpers to make them consistent with NL_SET_ERR_*
macros.
v2: drop incorrect second Fixes tag

The nci_conn_max_data_pkt_payload_size() function sometimes returns
-EPROTO so "max_size" needs to be signed for the error handling to
work. We can make "payload_size" an int as well.

When application uses TCP_QUEUE_SEQ socket option to
change tp->rcv_next, we must also update tp->copied_seq.
Otherwise, stuff relying on tcp_inq() being precise can
eventually be confused.
For example, tcp_zerocopy_receive() might crash because
it does not expect tcp_recv_skb() to return NULL.
We could add tests in various places to fix the issue,
or simply make sure tcp_inq() wont return a random value,
and leave fast path as it is.
Note that this fixes ioctl(fd, SIOCINQ, &val) at the same
time.

The GEO_TX_POWER_LIMIT command was sent although
there is no wgds table, so the fw got wrong SAR values
