Commit d3d657a908 ("i40e: update VFs of link state after
GET_VF_RESOURCES") modified the PF driver to notify a VF of
its link status immediately after it requests resources.
This was intended to fix reporting on VF drivers, so that they would
properly report link status.
However, some older VF drivers do not respond well to receiving a link
up notification before queues are enabled. This can cause their state
machine to think that it is safe to send traffic. This results in a Tx
hang on the VF.
More recent versions of the old i40evf and all versions of iavf are
resilient to these early link status messages. However, if a VM happens
to run an older version of the VF driver, this can be problematic.
Record whether the PF has actually enabled queues for the VF. When
reporting link status, always report link down if the queues aren't
enabled. In this way, the VF driver will never receive a link up
notification until after its queues are enabled.

net: fix regressions for generic-XDP
Thanks to Brandon Cazander, who wrote a very detailed bug report that
even used perf probe's on xdp-newbies mailing list, we discovered that
generic-XDP contains some regressions when using bpf_xdp_adjust_head().
First issue were that my selftests script, that use bpf_xdp_adjust_head(),
by mistake didn't use generic-XDP any-longer. That selftest should have
caught the real regression introduced in commit 458bf2f224 ("net: core:
support XDP generic on stacked devices.").
To verify this patchset fix the regressions, you can invoked manually via:
cd tools/testing/selftests/bpf/
sudo ./test_xdp_vlan_mode_generic.sh
sudo ./test_xdp_vlan_mode_native.sh
====================

When generic-XDP was moved to a later processing step by commit
458bf2f224 ("net: core: support XDP generic on stacked devices.")
a regression was introduced when using bpf_xdp_adjust_head.
The issue is that after this commit the skb->network_header is now
changed prior to calling generic XDP and not after. Thus, if the header
is changed by XDP (via bpf_xdp_adjust_head), then skb->network_header
also need to be updated again. Fix by calling skb_reset_network_header().

Change BPF selftest test_xdp_vlan.sh to (default) use generic XDP.
This selftest was created together with a fix for generic XDP, in commit
2972495699 ("net: fix generic XDP to handle if eth header was
mangled"). And was suppose to catch if generic XDP was broken again.
The tests are using veth and assumed that veth driver didn't support
native driver XDP, thus it used the (ip link set) 'xdp' attach that fell
back to generic-XDP. But veth gained native-XDP support in 948d4f214f
("veth: Add driver XDP"), which caused this test script to use
native-XDP.

The commit 069d11465a ("net/mlx5e: RX, Enhance legacy Receive Queue

or after bailed out the loop,
for (i = 0; i < mlx5_wq_cyc_get_size(&rq->wqe.wq); i++)
As the result, there could be some "frag" have uninitialized
value of "last_in_page".
Later, get_frag() obtains those "frag" and check "frag->last_in_page" in
mlx5e_put_rx_frag() and triggers the error during boot. Fix it by always
initializing "frag->last_in_page" to "false" in
mlx5e_init_frags_partition().

Currently init call of all actions (except ipt) init their 'parm'
structure as a direct pointer to nla data in skb. This leads to race
condition when some of the filter actions were initialized successfully
(and were assigned with idr action index that was written directly
into nla data), but then were deleted and retried (due to following
action module missing or classifier-initiated retry), in which case
action init code tries to insert action to idr with index that was
assigned on previous iteration. During retry the index can be reused
by another action that was inserted concurrently, which causes
unintended action sharing between filters.
To fix described race condition, save action idr index to temporary
stack-allocated variable instead on nla data.

Fix two reset-gpio sanity checks which were never converted to use
gpio_is_valid(), and make sure to use -EINVAL to indicate a missing
reset line also for the UART-driver module parameter and for the USB

This specifically prevents the UART and USB drivers from incidentally
trying to request and use gpio 0, and also avoids triggering a WARN() in

Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether
the previous wheel report was horizontal or vertical. Before
c01908a14b ("HID: input: add mapping for "Toggle Display" key") this
usage was being mapped to 'Relative.Misc'. After the patch it's simply
ignored (usage->type == 0 & usage->code == 0). Which ultimately makes
hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no
usage->type.
We shouldn't rely on a mapping for that usage as it's nonstandard and
doesn't really map to an input event. So we bypass the mapping and make
sure the custom event handling properly handles both reports.

The nr_allocated_banks and allocated banks are initialized as part of
tpm_chip_register. Currently, this is done as part of auto startup
function. However, some drivers, like the ibm vtpm driver, do not run
auto startup during initialization. This results in uninitialized memory
issue and causes a kernel panic during boot.
This patch moves the pcr allocation outside the auto startup function
into tpm_chip_register. This ensures that allocated banks are initialized
in any case.
Fixes: 879b589210 ("tpm: retrieve digest size of unknown algorithms with PCR read")

Instead of transmitting individual OGMv2 packets from the aggregation
queue merge those OGMv2 packets into a single one and transmit this
aggregate instead.
This reduces overhead as it saves an ethernet header and a transmission
per aggregated OGMv2 packet.

In preparation for the OGMv2 packet aggregation, hold OGMv2 packets for
up to BATADV_MAX_AGGREGATION_MS milliseconds (100ms) on per
hard-interface queues, before transmitting.
This allows us to later squash multiple OGMs into a single frame
and transmission for reduced overhead.

Fix assignment of the FM10K_FAULT_ADDR_LO register into fault->address
by using a bit-wise |= operation. Without this, the low address is
completely overwriting the high potion of the address. This caused the
fault to incorrectly return only the lower 32 bits of the fault address.

The driver currently uses a macro to decide whether we should use
NON_Q_VECTORS_PF or NON_Q_VECTORS_VF.
However, we also define NON_Q_VECTORS_VF to the same value as
NON_Q_VECTORS_PF. This means that the macro NON_Q_VECTORS(hw) will
always return the same value.
Let's just remove this macro, and replace it directly with an enum value
on the enum non_q_vectors.

as they are used as function pointers. The parameters in these functions
are not always used. Explicitly mark unused parameters with the

The page_addr variable is a void pointer. Incrementing it before calling
prefetch is technically undefined. Fix this by casting it to a u8*
pointer before incrementing it. This ensures that we increment the
pointer value in byte units, instead of relying on this undefined
behavior.
This was detected by cppcheck, and resolves the following warning
produced by that tool:

Prior to this commit, starting nconfig, xconfig or gconfig, and saving
the .config file more than once caused data loss, where a .config file
that contained only comments would be written to disk starting from the
second save operation.
This bug manifests itself because the SYMBOL_WRITTEN flag is never
cleared after the first call to conf_write, and subsequent calls to
conf_write then skip all of the configuration symbols due to the
SYMBOL_WRITTEN flag being set.
This commit resolves this issue by clearing the SYMBOL_WRITTEN flag
from all symbols before conf_write returns.
