The NETLINK_FIB_LOOKUP netlink family can be used to perform a FIB
lookup according to user provided parameters and communicate the result
back to user space.
Unmask the upper DSCP bits of the user-provided DS field before invoking
the IPv4 FIB lookup API so that in the future the lookup could be
performed according to the full DSCP value.
No functional changes intended since the upper DSCP bits are masked when
comparing against the TOS selectors in FIB rules and routes.

The helper performs a FIB lookup according to the parameters in the
'params' argument, one of which is 'tos'. According to the test in
test_tc_neigh_fib.c, it seems that BPF programs are expected to
initialize the 'tos' field to the full 8 bit DS field from the IPv4
header.

W=1 builds with GCC 14.2.0 warn that:
.../aq_ethtool.c:278:59: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 6 [-Wformat-truncation=]

278 | snprintf(tc_string, 8, "TC%d ", tc);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tc is always in the range 0 - cfg->tcs. And as cfg->tcs is a u8,
the range is 0 - 255. Further, on inspecting the code, it seems
that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so
the range is actually 0 - 8.
So, it seems that the condition that GCC flags will not occur.
But, nonetheless, it would be nice if it didn't emit the warning.
It seems that this can be achieved by changing the format specifier
from %d to %u, in which case I believe GCC recognises an upper bound
on the range of tc of 0 - 255. After some experimentation I think
this is due to the combination of the use of %u and the type of
cfg->tcs (u8).
Empirically, updating the type of the tc variable to unsigned int
has the same effect.
As both of these changes seem to make sense in relation to what the code
is actually doing - iterating over unsigned values - do both.
Compile tested only.

These are not directly related to that series, so I send them

Fixes for v6.11-rc5
1) Fixes from the virtual plane series, namely
- fix the list of formats for QCM2290 since it has no YUV support
- minor fix in dpu_plane_atomic_check_pipe() to check only for csc and
not csc and scaler while allowing yuv formats
- take rotation into account while allocating virtual planes
2) Fix to cleanup FB if dpu_format_populate_layout() fails. This fixes the

3) Fix to reset the phy link params before re-starting link training. This
fixes the 100% link training failure when someone starts modetest while
cable is connected
4) Long pending fix to fix a visual corruption seen for 4k modes. Root-cause
was we cannot support 4k@30 with 30bpp with 2 lanes so this is a critical
fix to use 24bpp for such cases
5) Fix to move dpu encoder's connector assignment to atomic_enable(). This

There is a difference between TLS configured (ie the user has
provisioned/requested a key) and TLS enabled (ie the connection
is encrypted with TLS). This becomes important for secure concatenation,
where the initial authentication is run on an unencrypted connection
(ie with TLS configured, but not enabled), and then the queue is reset to
run over TLS (ie TLS configured _and_ enabled).
So to differentiate between those two states store the generated
key in opts->tls_key (as we're using the same TLS key for all queues),
the key serial of the resulting TLS handshake in ctrl->tls_pskid
(to signal that TLS on the admin queue is enabled), and a simple
flag for the queues to indicated that TLS has been enabled.

TP8018 introduced a new TLS PSK identifier version (version 1), which appended

section 3.6.1.3 'TLS PSK and PSK Identity Derivation').
An original (version 0) identifier has the form:
NVMe0<type><hmac> <hostnqn> <subsysnqn>
and a version 1 identifier has the form:
NVMe1<type><hmac> <hostnqn> <subsysnqn> <hash>
This patch modifies the lookup algorthm to compare only the first part
of the identifier (excluding the hash value) to handle both version 0 and
version 1 identifiers.
And the spec declares 'version 0' identifiers obsolete, so the lookup
algorithm is modified to prever v1 identifiers.

iucv_alloc_device() gets a format string and a varying number of
arguments. This is incorrectly forwarded by calling dev_set_name() with
the format string and a va_list, while dev_set_name() expects also a
varying number of arguments.
Symptoms:
Corrupted iucv device names, which can result in log messages like:
sysfs: cannot create duplicate filename '/devices/iucv/hvc_iucv1827699952'

There is something wrong with ovs_drop_reasons. ovs_drop_reasons[0] is
"OVS_DROP_LAST_ACTION", but OVS_DROP_LAST_ACTION == __OVS_DROP_REASON + 1,
which means that ovs_drop_reasons[1] should be "OVS_DROP_LAST_ACTION".
And as Adrian tested, without the patch, adding flow to drop packets
results in:
drop at: do_execute_actions+0x197/0xb20 [openvsw (0xffffffffc0db6f97)
origin: software
input port ifindex: 8
timestamp: Tue Aug 20 10:19:17 2024 859853461 nsec
protocol: 0x800
length: 98
original length: 98
drop reason: OVS_DROP_ACTION_ERROR
With the patch, the same results in:
drop at: do_execute_actions+0x197/0xb20 [openvsw (0xffffffffc0db6f97)
origin: software
input port ifindex: 8
timestamp: Tue Aug 20 10:16:13 2024 475856608 nsec
protocol: 0x800
length: 98
original length: 98
drop reason: OVS_DROP_LAST_ACTION
Fix this by initializing ovs_drop_reasons with index.

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
Patch #1 disable BH when collecting stats via hardware offload to ensure
concurrent updates from packet path do not result in losing stats.
From Sebastian Andrzej Siewior.
Patch #2 uses write seqcount to reset counters serialize against reader.
Also from Sebastian Andrzej Siewior.
Patch #3 ensures vlan header is in place before accessing its fields,
according to KMSAN splat triggered by syzbot.

If a multicast address is removed but there are still some multicast
addresses, that address would remain programmed into the frame filter.
Fix this by explicitly setting the enable bit for each filter.

If promiscuous mode is disabled when there are fewer than four multicast
addresses, then it will not be reflected in the hardware. Fix this by
always clearing the promiscuous mode flag even when we program multicast
addresses.

After successfully programming the SPI flash with an MFPS auto update
image, the error sysfs attribute reports programming:timeout.
This is caused by an incorrect check on the return value from
wait_for_completion_timeout() in mpfs_auto_update_poll_complete().

If host supports Bus Lock Detect, KVM advertises it to guests even if
SVM support is absent. Additionally, guest wouldn't be able to use it
despite guest CPUID bit being set. Fix it by unconditionally clearing
the feature bit in KVM cpu capability.
