Bluetooth: hci_core/mgmt: move adv timeout to hdev
Currently the delayed work managing advertising duration and timeout is
part of the advertising instance structure. This is not correct as only
a single instance can be advertised at any given time. To implement
round robin advertising a single delayed work structure is needed.
To fix this the delayed work structure is being moved to the hci_dev

to make it clear that this is the remaining lifetime of the instance and

The current hci dev structure only supports a single advertising

already included Intel_NOP command for alignment.
This patch checks the next command and if the next command is Intel_NOP
command, it reads the Intel_NOP command and send them together.
For example, if the data from the firmware file looks like this:
8E FC 03 11 22 33 02 FC 03 00 00 00
Previously, btusb sends two commands:
09 FC 06 8E FC 03 11 22 33
09 FC 06 02 FC 03 00 00 00
This won't work because the length of parameters are 6 which violates

Bluetooth: Fix race condition with user channel and setup stage
During the initial setup stage of a controller, the low-level transport
is actually active. This means that HCI_UP is true. To avoid toggling
the transport off and back on again for normal operation the kernel
holds a grace period with HCI_AUTO_OFF that will turn the low-level
transport off in case no user is present.
The idea of the grace period is important to avoid having to initialize
all of the controller twice. So legacy ioctl and the new management
interface knows how to clear this grace period and then start normal
operation.
For the user channel operation this grace period has not been taken into
account which results in the problem that HCI_UP and HCI_AUTO_OFF are
set and the kernel will return EBUSY. However from a system point of
view the controller is ready to be grabbed by either the ioctl, the
management interface or the user channel.
This patch brings the user channel to the same level as the other two
entries for operating a controller.

ieee802154: Fix sockaddr_ieee802154 implicit padding information leak.
The AF_IEEE802154 sockaddr looks like this:
struct sockaddr_ieee802154 {
sa_family_t family; /* AF_IEEE802154 */
struct ieee802154_addr_sa addr;
};
struct ieee802154_addr_sa {
int addr_type;
u16 pan_id;
union {
u8 hwaddr[IEEE802154_ADDR_LEN];
u16 short_addr;
};
};
On most architectures there will be implicit structure padding here,
in two different places:
* In struct sockaddr_ieee802154, two bytes of padding between 'family'
(unsigned short) and 'addr', so that 'addr' starts on a four byte
boundary.
* In struct ieee802154_addr_sa, two bytes at the end of the structure,
to make the structure 16 bytes.
When calling recvmsg(2) on a PF_IEEE802154 SOCK_DGRAM socket, the
ieee802154 stack constructs a struct sockaddr_ieee802154 on the
kernel stack without clearing these padding fields, and, depending
on the addr_type, between four and ten bytes of uncleared kernel
stack will be copied to userspace.
We can't just insert two 'u16 __pad's in the right places and zero
those before copying an address to userspace, as not all architectures
insert this implicit padding -- from a quick test it seems that avr32,
cris and m68k don't insert this padding, while every other architecture
that I have cross compilers for does insert this padding.
The easiest way to plug the leak is to just memset the whole struct
sockaddr_ieee802154 before filling in the fields we want to fill in,
and that's what this patch does.

ieee802154/atusb: Add function for partial register writes
With this function we can set individual bits in the registers if needed.
With the old SR_VALUE macro we could only set one bit in the register
which was ok for some scenarios but not for all. With this subreg write
function we can now set more bits defined by the mask while not touching
the rest.
We start using it for the current SR_VALUE use case and will use it more
in upcoming patches.

ieee802154: Fix generation of random EUI-64 addresses.
Currently, ieee802154_random_extended_addr() has a 50% chance of
generating a group (multicast) address, while this function is used
for generating station addresses (which can't be group addresses)
for interfaces that don't have a hardware-provided address.
Also, in case get_random_bytes() generates the EUI-64 address
00:00:00:00:00:00:00:00 (extremely unlikely), which is an invalid
address, ieee802154_random_extended_addr() reacts by changing it
to 01:00:00:00:00:00:00:00, which is an invalid station address as
well, as it is a group address.
This patch changes the address generation procedure to grab eight
random bytes, treat that as an EUI-64, and then clear the Group
address bit and set the Locally Administered bit, which is in
line with how eth_random_addr() generates random EUI-48s.

bpf: add missing rcu protection when releasing programs from prog_array
Normally the program attachment place (like sockets, qdiscs) takes
care of rcu protection and calls bpf_prog_put() after a grace period.
The programs stored inside prog_array may not be attached anywhere,
so prog_array needs to take care of preserving rcu protection.
Otherwise bpf_tail_call() will race with bpf_prog_put().
To solve that introduce bpf_prog_put_rcu() helper function and use
it in 3 places where unattached program can decrement refcnt:
closing program fd, deleting/replacing program in prog_array.
Fixes:

The following patchset contains Netfilter updates for net-next, they are:
1) default CONFIG_NETFILTER_INGRESS to y for easier compile-testing of all
options.
2) Allow to bind a table to net_device. This introduces the internal
NFT_AF_NEEDS_DEV flag to perform a mandatory check for this binding.
This is required by the next patch.
3) Add the 'netdev' table family, this new table allows you to create ingress
filter basechains. This provides access to the existing nf_tables features
from ingress.

net: systemport: rewrite bcm_sysport_rx_refill
Currently, bcm_sysport_desc_rx() calls bcm_sysport_rx_refill() at the end of Rx
packet processing loop, after the current Rx packet has already been passed to
napi_gro_receive(). However, bcm_sysport_rx_refill() might fail to allocate a new
Rx skb, thus leaving a hole on the Rx queue where no valid Rx buffer exists.
To eliminate this situation:
1. Rewrite bcm_sysport_rx_refill() to retain the current Rx skb on the
Rx queue if a new replacement Rx skb can't be allocated and DMA-mapped.
In this case, the data on the current Rx skb is effectively dropped.
2. Modify bcm_sysport_desc_rx() to call bcm_sysport_rx_refill() at the
top of Rx packet processing loop, so that the new replacement Rx skb is
already in place before the current Rx skb is processed.
This is loosely inspired from

net: thunderx: add 64-bit dependency
The thunderx ethernet driver fails to build on architectures
that do not have an atomic readq() and writeq() function for
64-bit PCI bus access:
drivers/net/ethernet/cavium/thunder/thunder_bgx.c: In function 'bgx_reg_read':
include/asm-generic/io.h:195:23: error: implicit declaration of function 'readq' [-Werror=implicit-function-declaration]
It seems impossible to get this driver to work on most 32-bit
hardware, so it's better to add an explicit dependency, in
order to let us keep building 'allmodconfig' kernels on
all architectures.
As the driver is meant for the internal hardware on an arm64 SoC, this
is not a problem for usability. Allowing the build on all 64-bit
architectures rather than just CONFIG_ARM64 on the other hand means that
we get the benefit of build testing on x86.
