Commit 272970be3dab ("Bluetooth: hci_qca: Fix driver shutdown on closed
serdev") will cause below regression issue:
BT can't be enabled after below steps:
cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure
if property enable-gpios is not configured within DT|ACPI for QCA6390.
The commit is to fix a use-after-free issue within qca_serdev_shutdown()
by adding condition to avoid the serdev is flushed or wrote after closed
but also introduces this regression issue regarding above steps since the
VSC is not sent to reset controller during warm reboot.
Fixed by sending the VSC to reset controller within qca_serdev_shutdown()
once BT was ever enabled, and the use-after-free issue is also fixed by
this change since the serdev is still opened before it is flushed or wrote.
Verified by the reported machine Dell XPS 13 9310 laptop over below two
kernel commits:
commit e00fc2700a3f ("Bluetooth: btusb: Fix triggering coredump
implementation for QCA") of bluetooth-next tree.
commit b23d98d46d28 ("Bluetooth: btusb: Fix triggering coredump

qos->ucast interval reffers to the SDU interval, and should not
be set to the interval value reported by the LE CIS Established
event since the latter reffers to the ISO interval. These two
interval are not the same thing:
BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 6, Part G
Isochronous interval:
The time between two consecutive BIS or CIS events (designated
ISO_Interval in the Link Layer)
SDU interval:
The nominal time between two consecutive SDUs that are sent or
received by the upper layer.
So this instead uses the following formula from the spec to calculate
the resulting SDU interface:
BLUETOOTH CORE SPECIFICATION Version 5.4 | Vol 6, Part G
page 3075:
Transport_Latency_C_To_P = CIG_Sync_Delay + (FT_C_To_P) ×
ISO_Interval + SDU_Interval_C_To_P
Transport_Latency_P_To_C = CIG_Sync_Delay + (FT_P_To_C) ×
ISO_Interval + SDU_Interval_P_To_C

Admin queue command for shutdown AQ contains a flag to indicate driver
unload. However, the flag is always set in the driver, even for resets. It
can cause the firmware to consider driver as unloaded once the PF reset is
triggered on all ports of device, which could lead to unexpected results.
Add an additional function parameter to functions that shutdown AQ,
indicating whether the driver is actually unloading.

"Simple stuff:
- NULL ptr/err ptr deref fixes
- fix for getting wedged on shutdown after journal error
- fix missing recalc_capacity() call, capacity now changes correctly
after a device goes read only
however: our capacity calculation still doesn't take into account
when we have mixed ro/rw devices and the ro devices have data on
them, that's going to be a more involved fix to separate accounting
for "capacity used on ro devices" and "capacity used on rw devices"
- boring syzbot stuff
Slightly more involved:
- discard, invalidate workers are now per device
this has the effect of simplifying how we take device refs in these
paths, and the device ref cleanup fixes a longstanding race between
the device removal path and the discard path
- fixes for how the debugfs code takes refs on btree_trans objects we
have debugfs code that prints in use btree_trans objects.
It uses closure_get() on trans->ref, which is mainly for the cycle
detector, but the debugfs code was using it on a closure that may
have hit 0, which is not allowed; for performance reasons we cannot
avoid having not-in-use transactions on the global list.

Support tracking of up to 65535 packets per table entry instead of just
255 to better facilitate longer term tracking or higher throughput
scenarios.
Note how this aligns sizes of struct recent_entry's 'nstamps' and
'index' fields when 'nstamps' was larger before. This is unnecessary as
the value of 'nstamps' grows along with that of 'index' after being
initialized to 1 (see recent_entry_update()). Its value will thus never
exceed that of 'index' and therefore does not need to provide space for
larger values.

Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:
struct foo {
int count;
char buf[];
};
struct bar {
int count;
struct foo data[] __counted_by(count);
};
because the size of data cannot be calculated with the standard array
size formula:
sizeof(struct foo) * count
This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the
ports member of 'struct mxser_board' triggers this restriction,
resulting in:
drivers/tty/mxser.c:291:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct mxser_port' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
291 | struct mxser_port ports[] __counted_by(nports);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

An unintended consequence of commit 9c573cd31343 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.
The prior intent of the per-architecture limits were:
arm64: capped at 0x1FF (9 bits), 5 bits effective
powerpc: uncapped (10 bits), 6 or 7 bits effective
riscv: uncapped (10 bits), 6 bits effective
x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
s390: capped at 0xFF (8 bits), undocumented effective entropy
Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

We got another report that CT1000BX500SSD1 does not work with LPM.
If you look in libata-core.c, we have six different Crucial devices that
are marked with ATA_HORKAGE_NOLPM. This model would have been the seventh.
(This quirk is used on Crucial models starting with both CT* and
Crucial_CT*)
It is obvious that this vendor does not have a great history of supporting
LPM properly, therefore, add the ATA_HORKAGE_NOLPM quirk for all Crucial
BX SSD1 models.

We cannot use CLONE_VFORK because we also need to wait for the timeout
signal.
Restore tests timeout by using the original fork() call in __run_test()
but also in __TEST_F_IMPL(). Also fix a race condition when waiting for
the test child process.
Because test metadata are shared between test processes, only the
parent process must set the test PID (child). Otherwise, t->pid may be
set to zero, leading to inconsistent error cases:
# RUN layout1.rule_on_mountpoint ...
# rule_on_mountpoint: Test ended in some other way [127]
# OK layout1.rule_on_mountpoint
ok 20 layout1.rule_on_mountpoint
As safeguards, initialize the "status" variable with a valid exit code,
and handle unknown test exits as errors.
The use of fork() introduces a new race condition in landlock/fs_test.c
which seems to be specific to hostfs bind mounts, but I haven't found
the root cause and it's difficult to trigger. I'll try to fix it with
another patch.

ConnectX devices lack ability to count payload data byte size which is
needed for SA to return to libreswan for rekeying.
As a solution let's approximate that by decreasing headers size from
total size counted by flow steering. The calculation doesn't take into
account any other headers which can be in the packet (e.g. IP extensions).

Currently, ingress acl is used for three features. It is created only
when vport metadata match and prio tag are enabled. But active-backup
lag mode also uses it. It is independent of vport metadata match and
prio tag. And vport metadata match can be disabled using the
following devlink command:
# devlink dev param set pci/0000:08:00.0 name esw_port_metadata \
value false cmode runtime
If ingress acl is not created, will hit panic when creating drop rule
for active-backup lag mode. If always create it, there will be about
5% performance degradation.
Fix it by creating ingress acl when needed. If esw_port_metadata is
true, ingress acl exists, then create drop rule using existing
ingress acl. If esw_port_metadata is false, create ingress acl and
then create drop rule.

Due a bug in the device max_num_eqs doesn't always reflect a written

====================
selftest: Clean-up and stabilize mirroring tests
The mirroring selftests work by sending ICMP traffic between two hosts.
Along the way, this traffic is mirrored to a gretap netdevice, and counter
taps are then installed strategically along the path of the mirrored
traffic to verify the mirroring took place.
The problem with this is that besides mirroring the primary traffic, any
other service traffic is mirrored as well. At the same time, because the
tests need to work in HW-offloaded scenarios, the ability of the device to
do arbitrary packet inspection should not be taken for granted. Most tests
therefore simply use matchall, one uses flower to match on IP address.
As a result, the selftests are noisy.
mirror_test() accommodated this noisiness by giving the counters an
allowance of several packets. But that only works up to a point, and on
busy systems won't be always enough.
In this patch set, clean up and stabilize the mirroring selftests. The
original intention was to port the tests over to UDP, but the logic of
ICMP ends up being so entangled in the mirroring selftests that the
changes feel overly invasive. Instead, ICMP is kept, but where possible,
we match on ICMP message type, thus filtering out hits by other ICMP
messages.
Where this is not practical (where the counter tap is put on a device
that carries encapsulated packets), switch the counter condition to _at
least_ X observed packets. This is less robust, but barely so --
probably the only scenario that this would not catch is something like
erroneous packet duplication, which would hopefully get caught by the
numerous other tests in this extensive suite.
- Patches #1 to #3 clean up parameters at various helpers.
- Patches #4 to #6 stabilize the mirroring selftests as described above.
- Mirroring tests currently allow testing SW datapath even on HW
netdevices by trapping traffic to the SW datapath. This complicates
the tests a bit without a good reason: to test SW datapath, just run
the selftests on the veth topology. Thus in patch #7, drop support for
this dual SW/HW testing.
- At this point, some cleanups were either made possible by the previous
patches, or were always possible. In patches #8 to #11, realize these
cleanups.
- In patch #12, fix mlxsw mirror_gre selftest to respect setting TESTS.

The mirroring tests are currently run in a skip_hw and optionally a skip_sw
mode. The former tests the SW datapath, the latter the HW datapath, if
available. In order to be able to test SW datapath on HW loopbacks, traps
are installed on ingress to get traffic from the HW datapath to the SW one.
This adds an unnecessary complexity when it would be much simpler to just
use a veth-based topology to test the SW datapath. Thus drop all the code
that supports this dual testing.

mirror_test() accommodated this noisiness by giving the counters an
allowance of several packets. But in the previous patch, where possible,
counter taps were changed to match only on an exact ICMP message. At least
in those cases, we can demand an exact number of packets to match.
Where the tap is installed on a connective netdevice, the exact matching is
not practical (though with u32, anything is possible). In those places,
there should still be some leeway -- and probably bigger than before,
because experience shows that these tests are very noisy.
To that end, change mirror_test() so that it can be either called with an
exact number to expect, or with an expression. Where leeway is needed,
adjust callers to pass a ">= 10" instead of mere 10.

However, often the counter tap is installed at the remote end of the gretap
tunnel. Since this is a SW-datapath scenario anyway, we can make the filter
arbitrarily accurate.
Thus in this patch, add parameters forward_type and backward_type to
several mirroring test helpers, as some other helpers already have. Then
change do_test_span_dir_ips() to instead of installing one generic tap and
using it for test in both directions, install the tap for each direction
separately, matching on the ICMP type given by these parameters.

The test works by sending packets through a tunnel, whence they are
forwarded to a LAG. One of the LAG children is removed from the LAG prior
to the exercise, and the test then counts how many packets pass through the
other one. The issue with this is that it counts all packets, not just the
encapsulated ones.
So instead add a second gretap endpoint to receive the sent packets, and
check reception counters there.

In some functions, argument-forwarding through "$@" without listing the
individual arguments explicitly is fundamental to the operation of a
function. E.g. xfail_on_veth() should be able to run various tests in the
fail-to-xfail regime, and usage of "$@" is appropriate as an abstraction
mechanism. For functions such as simple_if_init(), $@ is a handy way to
pass an array.
In other functions, it's merely a mechanism to save some typing, which
however ends up obscuring the real arguments and makes life hard for those
that end up reading the code.
This patch adds some of the implicit function arguments and correspondingly
expands $@'s. In several cases this will come in handy as following patches
adjust the parameter lists.

====================
Add ability to flash modules' firmware
CMIS compliant modules such as QSFP-DD might be running a firmware that
can be updated in a vendor-neutral way by exchanging messages between
the host and the module as described in section 7.2.2 of revision
4.0 of the CMIS standard.
According to the CMIS standard, the firmware update process is done
using a CDB commands sequence.
CDB (Command Data Block Message Communication) reads and writes are
performed on memory map pages 9Fh-AFh according to the CMIS standard,
section 8.12 of revision 4.0.
Add a pair of new ethtool messages that allow:
* User space to trigger firmware update of transceiver modules
* The kernel to notify user space about the progress of the process
The user interface is designed to be asynchronous in order to avoid RTNL
being held for too long and to allow several modules to be updated
simultaneously. The interface is designed with CMIS compliant modules in
mind, but kept generic enough to accommodate future use cases, if these
arise.
The kernel interface that will implement the firmware update using CDB
command will include 2 layers that will be added under ethtool:
* The upper layer that will be triggered from the module layer, is
cmis_ fw_update.
* The lower one is cmis_cdb.
In the future there might be more operations to implement using CDB
commands. Therefore, the idea is to keep the cmis_cdb interface clean and
the cmis_fw_update specific to the cdb commands handling it.
The communication between the kernel and the driver will be done using
two ethtool operations that enable reading and writing the transceiver
module EEPROM.
The operation ethtool_ops::get_module_eeprom_by_page, that is already
implemented, will be used for reading from the EEPROM the CDB reply,
e.g. reading module setting, state, etc.
The operation ethtool_ops::set_module_eeprom_by_page, that is added in
the current patchset, will be used for writing to the EEPROM the CDB
command such as start firmware image, run firmware image, etc.
Therefore in order for a driver to implement module flashing, that
driver needs to implement the two functions mentioned above.
Patchset overview:
Patch #1-#2: Implement the EEPROM writing in mlxsw.
Patch #3: Define the interface between the kernel and user space.
Patch #4: Add ability to notify the flashing firmware progress.
Patch #5: Veto operations during flashing.
Patch #6: Add extended compliance codes.
Patch #7: Add the cdb layer.
Patch #8: Add the fw_update layer.
Patch #9: Add ability to flash transceiver modules' firmware.
v8:
Patch #7:
* In the ethtool_cmis_wait_for_cond() evaluate the condition once more
to decide if the error code should be -ETIMEDOUT or something else.
* s/netdev_err/netdev_err_once.
v7:
Patch #4:
* Return -ENOMEM instead of PTR_ERR(attr) on
ethnl_module_fw_flash_ntf_put_err().
Patch #9:
* Fix Warning for not unlocking the spin_lock in the error flow
on module_flash_fw_work_list_add().
* Avoid the fall-through on ethnl_sock_priv_destroy().
v6:
* Squash some of the last patch to patch #5 and patch #9.
Patch #3:
* Add paragraph in .rst file.
Patch #4:
* Reserve '1' more place on SKB for NUL terminator in
the error message string.
* Add more prints on error flow, re-write the printing
function and add ethnl_module_fw_flash_ntf_put_err().
* Change the communication method so notification will be
sent in unicast instead of multicast.
* Add new 'struct ethnl_module_fw_flash_ntf_params' that holds
the relevant info for unicast communication and use it to
send notification to the specific socket.
* s/nla_put_u64_64bit/nla_put_uint/
Patch #7:
* In ethtool_cmis_cdb_init(), Use 'const' for the 'params'
parameter.
Patch #8:
* Add a list field to struct ethtool_module_fw_flash for
module_fw_flash_work_list that will be presented in the next
patch.
* Move ethtool_cmis_fw_update() cleaning to a new function that
will be represented in the next patch.
* Move some of the fields in struct ethtool_module_fw_flash to
a separate struct, so ethtool_cmis_fw_update() will get only
the relevant parameters for it.
* Edit the relevant functions to get the relevant params for
them.
* s/CMIS_MODULE_READY_MAX_DURATION_USEC/CMIS_MODULE_READY_MAX_DURATION_MSEC
Patch #9:
* Add a paragraph in the commit message.
* Rename labels in module_flash_fw_schedule().
* Add info to genl_sk_priv_*() and implement the relevant
callbacks, in order to handle properly a scenario of closing
the socket from user space before the work item was ended.
* Add a list the holds all the ethtool_module_fw_flash struct
that corresponds to the in progress work items.
* Add a new enum for the socket types.
* Use both above to identify a flashing socket, add it to the
list and when closing socket affect only the flashing type.
* Create a new function that will get the work item instead of
ethtool_cmis_fw_update().
* Edit the relevant functions to get the relevant params for
them.
* The new function will call the old ethtool_cmis_fw_update(),
and do the cleaning, so the existence of the list should be
completely isolated in module.c.

Add the ability to flash the modules' firmware by implementing the
interface between the user space and the kernel.
Example from a succeeding implementation:
# ethtool --flash-module-firmware swp40 file test.bin
Transceiver module firmware flashing started for device swp40
Transceiver module firmware flashing in progress for device swp40
Progress: 99%
Transceiver module firmware flashing completed for device swp40
In addition, add infrastructure that allows modules to set socket-specific
private data. This ensures that when a socket is closed from user space
during the flashing process, the right socket halts sending notifications
to user space until the work item is completed.
