Bluetooth: vhci: Fix info leak in force_devcd_write()
There are a number of bugs here:
1) If "count" is less than sizeof(dump_data.data) then it copies
uninitialized data.
2) If simple_write_to_buffer() returns -EFAULT then we run into a
problem "ret < count" comparison. "count" is an unsigned long so the
comparison is type promoted to unsigned long and the negative returns
become high positive values. That also results in copying
uninitialized data.
3) If "*ppos" is non-zero then the first part of the dump_data
buffer is uninitialized. Using copy_from_user() instead of

Bluetooth: btnxpuart: No need to check the received bootloader signature
We can never assume the uart will deliver a complete packet to the BT
layer at once, the expected packet may be divided into several parts by
uart as uart doesn't know the received packet size, the received data
count may mismatch with the expected packet size, so here
is_valid_bootloader_signature() check may always return false.
Even we remove the count check in is_valid_bootloader_signature(), then
the first part of the data which includes the packet type can pass the
is_valid_bootloader_signature() check, but the remaining parts don't
have the packet type data still cannot pass the check, here return
directly will cause the data loss.
So need to remove the received bootloader signature check here, the
h4_recv_buf() can help us combine the different data received into one
packet. If any out-of-sync or incomplete bootloader signature is received,
it is safe to ignore and discard it, and process the next bootloader
signature.

Bluetooth: hci_bcm: Fall back to getting bdaddr from EFI if not set
On some devices the BCM Bluetooth adapter does not have a valid bdaddr set.
btbcm.c currently sets HCI_QUIRK_INVALID_BDADDR to indicate when this is
the case. But this requires users to manual setup a btaddr, by doing e.g.:
btmgmt -i hci0 public-addr 'B0:F1:EC:82:1D:B3'
Which means that Bluetooth will not work out of the box on such devices.
To avoid this (where possible) hci_bcm sets: HCI_QUIRK_USE_BDADDR_PROPERTY
which tries to get the bdaddr from devicetree.
But this only works on devicetree platforms. On UEFI based platforms
there is a special Broadcom UEFI variable which when present contains
the devices bdaddr, just like how there is another UEFI variable which
contains wifi nvram contents including the wifi MAC address.
Add support for getting the bdaddr from this Broadcom UEFI variable,
so that Bluetooth will work OOTB for users on devices where this
UEFI variable is present.

Bluetooth: Add support for hci devcoredump
Add devcoredump APIs to hci core so that drivers only have to provide
the dump skbs instead of managing the synchronization and timeouts.
The devcoredump APIs should be used in the following manner:
- hci_devcoredump_init is called to allocate the dump.
- hci_devcoredump_append is called to append any skbs with dump data
OR hci_devcoredump_append_pattern is called to insert a pattern.
- hci_devcoredump_complete is called when all dump packets have been
sent OR hci_devcoredump_abort is called to indicate an error and
cancel an ongoing dump collection.
The high level APIs just prepare some skbs with the appropriate data and
queue it for the dump to process. Packets part of the crashdump can be
intercepted in the driver in interrupt context and forwarded directly to
the devcoredump APIs.
Internally, there are 5 states for the dump: idle, active, complete,
abort and timeout. A devcoredump will only be in active state after it
has been initialized. Once active, it accepts data to be appended,
patterns to be inserted (i.e. memset) and a completion event or an abort
event to generate a devcoredump. The timeout is initialized at the same
time the dump is initialized (defaulting to 10s) and will be cleared
either when the timeout occurs or the dump is complete or aborted.

Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets
This adds a driver based on serdev driver for the NXP BT serial protocol
based on running H:4, which can enable the built-in Bluetooth device
inside an NXP BT chip.
This driver has Power Save feature that will put the chip into sleep state
whenever there is no activity for 2000ms, and will be woken up when any
activity is to be initiated over UART.
This driver enables the power save feature by default by sending the vendor
specific commands to the chip during setup.
During setup, the driver checks if a FW is already running on the chip
by waiting for the bootloader signature, and downloads device specific FW
file into the chip over UART if bootloader signature is received..

A similar case is when adapter is powering off. However, we still wait
for the peer's reply in this case. Therefore, if the peer is
unresponsive, the command will time out and the power off sequence
will fail, causing "bluetooth powered on by itself" to users.

since version 4.0 only recommends and no longer requires specific
interface numbers.
While earlier Bluetooth versions, i.e. 2.1 + EDR and 3.0 + HS, contain
required configuration table in Volume 4 - Host Controller Interface
Part B - USB Transport Layer, Bluetooth Core Specification Addendum 2
changes the table from required to recommended configuration.

net/sched: act_pedit: minor improvements
This series aims to improve the code and usability of act_pedit for
netlink users.
Patches 1-2 improves error reporting for extended keys parsing with extack.
Patch 3 checks the static offsets a priori on create/update. Currently,
this is done at the datapath for both static and runtime offsets.
Patch 4 removes a check from the datapath which is redundant since the
netlink parsing validates the key types.
Patch 5 changes the 'pr_info()' calls in the datapath to rate limited

behind skb_vlan_eth_hdr()). The only patch which is more "interesting"

Another potential caller of __skb_vlan_pop() on xmit (and therefore

net: dsa: tag_ocelot: call only the relevant portion of __skb_vlan_pop() on TX
ocelot_xmit_get_vlan_info() calls __skb_vlan_pop() as the most
appropriate helper I could find which strips away a VLAN header.
That's all I need it to do, but __skb_vlan_pop() has more logic, which
will become incompatible with the future revert of commit
6d1ccff62780
("net: reset mac header in dev_start_xmit()").
Namely, it performs a sanity check on skb_mac_header(), which will stop
being set after the above revert, so it will return an error instead of
removing the VLAN tag.
ocelot_xmit_get_vlan_info() gets called in 2 circumstances:
(1) the port is under a VLAN-aware bridge and the bridge sends
VLAN-tagged packets
(2) the port is under a VLAN-aware bridge and somebody else (an 8021q
upper) sends VLAN-tagged packets (using a VID that isn't in the
bridge vlan tables)
In case (1), there is actually no bug to defend against, because
br_dev_xmit() calls skb_reset_mac_header() and things continue to work.
However, in case (2), illustrated using the commands below, it can be
seen that our intervention is needed, since __skb_vlan_pop() complains:
$ ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
$ ip link set $eth master br0 && ip link set $eth up
$ ip link add link $eth name $eth.100 type vlan id 100 && ip link set $eth.100 up
$ ip addr add 192.168.100.1/24 dev $eth.100
I could fend off the checks in __skb_vlan_pop() with some
skb_mac_header_was_set() calls, but seeing how few callers of
__skb_vlan_pop() there are from TX paths, that seems rather
unproductive.
As an alternative solution, extract the bare minimum logic to strip a
VLAN header, and move it to a new helper named vlan_remove_tag(), close
to the definition of vlan_insert_tag(). Document it appropriately and
make ocelot_xmit_get_vlan_info() call this smaller helper instead.
Seeing that it doesn't appear illegal to test skb->protocol in the TX
path, I guess it would be a good for vlan_remove_tag() to also absorb
the vlan_set_encap_proto() function call.

3) Maher migrates vnic diagnostic counters reporting from debugfs to a
dedicated devlink health reporter
Maher Says:
===========
net/mlx5: Expose vnic diagnostic counters using devlink
Currently, vnic diagnostic counters are exposed through the following
debugfs:
$ ls /sys/kernel/debug/mlx5/0000:08:00.0/esw/vf_0/vnic_diag/
cq_overrun
quota_exceeded_command
total_q_under_processor_handle
invalid_command
send_queue_priority_update_flow
nic_receive_steering_discard
The current design does not allow the hypervisor to view the diagnostic
counters of its VFs, in case the VFs get bound to a VM. In other words,
the counters are not exposed for representor interfaces.
Furthermore, the debugfs design is inconvenient future-wise, in case more
counters need to be reported by the driver in the future.
As these counters pertain to vNIC health, it is more appropriate to
utilize the devlink health reporter to expose them.
Thus, this patchest includes the following changes:
* Drop the current vnic diagnostic counters debugfs interface.
* Add a vnic devlink health reporter for PFs/VFs core devices, which
when diagnosed will dump vnic diagnostic counter values that are
queried from FW.
* Add a vnic devlink health reporter for the representor interface, which
serves the same purpose listed in the previous point, in addition to
allowing the hypervisor to view its VFs diagnostic counters, even when
the VFs are bounded to external VMs.
Example of devlink health reporter usage is:
$devlink health diagnose pci/0000:08:00.0 reporter vnic

Patch "net: dst: Prevent false sharing vs. dst_entry:: __refcnt" moved
rt_uncached and rt_uncached_list fields from rtable struct to dst
struct, so they are more zeroed by memset_after(xdst, 0, u.dst) in
xfrm_alloc_dst().
Note that rt_uncached (list_head) was never properly initialized at
alloc time, but xfrm[46]_dst_destroy() is written in such a way that
it was not an issue thanks to the memset:
if (xdst->u.rt.dst.rt_uncached_list)
rt_del_uncached_list(&xdst->u.rt);
The route code does it the other way around: rt_uncached_list is
assumed to be valid IIF rt_uncached list_head is not empty:
void rt_del_uncached_list(struct rtable *rt)
{
if (!list_empty(&rt->dst.rt_uncached)) {
struct uncached_list *ul = rt->dst.rt_uncached_list;
spin_lock_bh(&ul->lock);
list_del_init(&rt->dst.rt_uncached);
spin_unlock_bh(&ul->lock);
}
}
This patch adds mandatory rt_uncached list_head initialization in
generic dst_init(), and adapt xfrm[46]_dst_destroy logic to match the
rest of the code.

net: phy: add basic driver for NXP CBTX PHY
The CBTX PHY is a Fast Ethernet PHY integrated into the SJA1110 A/B/C
automotive Ethernet switches.
It was hoped it would work with the Generic PHY driver, but alas, it
doesn't. The most important reason why is that the PHY is powered down
by default, and it needs a vendor register to power it on.
It has a linear memory map that is accessed over SPI by the SJA1110
switch driver, which exposes a fake MDIO controller. It has the
following (and only the following) standard clause 22 registers:
0x0: MII_BMCR
0x1: MII_BMSR
0x2: MII_PHYSID1
0x3: MII_PHYSID2
0x4: MII_ADVERTISE
0x5: MII_LPA
0x6: MII_EXPANSION
0x7: the missing MII_NPAGE for Next Page Transmit Register
Every other register is vendor-defined.
The register map expands the standard clause 22 5-bit address space of
0x20 registers, however the driver does not need to access the extra
registers for now (and hopefully never). If it ever needs to do that, it
is possible to implement a fake (software) page switching mechanism
between the PHY driver and the SJA1110 MDIO controller driver.
Also, Auto-MDIX is turned off by default in hardware, the driver turns
it on by default and reports the current status. I've tested this with a
VSC8514 link partner and a crossover cable, by forcing the mode on the
link partner, and seeing that the CBTX PHY always sees the reverse of
the mode forced on the VSC8514 (and that traffic works). The link
doesn't come up (as expected) if MDI modes are forced on both ends in
the same way (with the cross-over cable, that is).

The tests above can't be in a single file because:
