In the format of synthetic events, the "gfp_t" is shown as "signed:1",
but in fact the "gfp_t" is "unsigned", should be shown as "signed:0".
The issue can be reproduced by the following commands:
echo 'memlatency u64 lat; unsigned int order; gfp_t gfp_flags; int migratetype' > /sys/kernel/debug/tracing/synthetic_events

Some arrays are not capable of returning RTPG data during state
transitioning, but rather return an 'LUN not accessible, asymmetric access
state transition' sense code. In these cases we can set the state to
'transitioning' directly and don't need to evaluate the RTPG data (which we
won't have anyway).

Some paths call skb_queue_empty() without holding
the queue lock. We must use a barrier in order
to not let the compiler do strange things, and avoid
KCSAN splats.
Adding a barrier in skb_queue_empty() might be overkill,
I prefer adding a new helper to clearly identify
points where the callers might be lockless. This might
help us finding real bugs.
The corresponding WRITE_ONCE() should add zero cost
for current compilers.

[ Upstream commit ca5f8d2dd5229ccacdd5cfde1ce4d32b0810e454 ]
Creating of an SMC-R connection with vlan-id fails, because
smc_listen_work() determines the vlan_id of the connection,
saves it in struct smc_init_info ini, but clears the ini area
again if SMC-D is not applicable.
This patch just resets the ISM device before investigating
SMC-R availability.

[ Upstream commit 6d6b0d0d5afc8c4c84b08261260ba11dfa5206f2 ]
When in slave mode, an arbitration loss (ARLO) may be detected before the
slave had a chance to detect the stop condition (STOPF in ISR).
This is seen when two master + slave adapters switch their roles. It
provokes the i2c bus to be stuck, busy as SCL line is stretched.
- the I2C_SLAVE_STOP event is never generated due to STOPF flag is set but
don't generate an irq (race with ARLO irq, STOPIE is masked). STOPF flag
remains set until next master xfer (e.g. when STOPIE irq get unmasked).
In this case, completion is generated too early: immediately upon new
transfer request (then it doesn't send all data).
- Some data get stuck in TXDR register. As a consequence, the controller
stretches the SCL line: the bus gets busy until a future master transfer
triggers the bus busy / recovery mechanism (this can take time... and
may never happen at all)
So choice is to let the STOPF being detected by the slave isr handler,
to properly handle this stop condition. E.g. don't mask IRQs in error
handler, when the slave is running.

[ Upstream commit f9c32435ab7221d1d6cb35738fa85a2da012b23e ]
When rxrpc_recvmsg_data() sets the return value to 1 because it's drained
all the data for the last packet, it checks the last-packet flag on the
whole packet - but this is wrong, since the last-packet flag is only set on
the final subpacket of the last jumbo packet. This means that a call that
receives its last packet in a jumbo packet won't complete properly.
Fix this by having rxrpc_locate_data() determine the last-packet state of
the subpacket it's looking at and passing that back to the caller rather
than having the caller look in the packet header. The caller then needs to
cache this in the rxrpc_call struct as rxrpc_locate_data() isn't then
called again for this packet.
Fixes: 248f219cb8bc ("rxrpc: Rewrite the data and ack handling code")
Fixes: e2de6c404898 ("rxrpc: Use info in skbuff instead of reparsing a jumbo packet")

bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available
on all Raspberry Pi boards. But there is no driver for this particual
GPIO on CM3 in mainline yet, so this node was left incomplete without
the actual GPIO definition. Since commit 025bf37725f1 ("gpio: Fix return
value mismatch of function gpiod_get_from_of_node()") this causing probe
issues of the leds-gpio driver for users of the CM3 dtsi file.
leds-gpio: probe of leds failed with error -2
Until we have the necessary GPIO driver hide the ACT node for CM3
to avoid this.

In case of master pending state, it should not trigger a master
command, otherwise data could be corrupted because this H/W shares
the same data buffer for slave and master operations. It also means
that H/W command queue handling is unreliable because of the buffer
sharing issue. To fix this issue, it clears command queue if a
master command is queued in pending state to use S/W solution
instead of H/W command queue handling. Also, it refines restarting
mechanism of the pending master command.

[ Upstream commit e56bd641ca61beb92b135298d5046905f920b734 ]
This is due to error in over budget processing.
When dealing with high throughput, the used buffers
that exceeds the budget is not cleaned up. In addition,
it takes a lot of cycles to clean up the used buffer,
and then the buffer where the valid data is located can take effect.

[ Upstream commit 41860cc447045c811ce6d5a92f93a065a691fe8e ]
Modify plic_init() to skip .dts interrupt contexts other
than supervisor external interrupt.
The .dts entry for plic may specify multiple interrupt contexts.
For example, it may assign two entries IRQ_M_EXT and IRQ_S_EXT,
in that order, to the same interrupt controller. This patch
modifies plic_init() to skip the IRQ_M_EXT context since
IRQ_S_EXT is currently the only supported context.
If IRQ_M_EXT is not skipped, plic_init() will report "handler
already present for context" when it comes across the IRQ_S_EXT
context in the next iteration of its loop.
Without this patch, .dts would have to be edited to replace the
value of IRQ_M_EXT with -1 for it to be skipped.

[ Upstream commit 62931ac2f9015ea38d80494ec37658ab3df6a6d7 ]
Since commit abf4923e97c3 ("i2c: mediatek: disable zero-length transfers
for mt8183"), there is a NULL pointer dereference for all the SoCs
that don't have any quirk. mtk_i2c_functionality is not checking that
the quirks pointer is not NULL before starting to use it.
This commit add a call to i2c_check_quirks which will check whether
the quirks pointer is set, and if so will check if the IP has the
NO_ZERO_LEN quirk.

We already do this for the most part, except in timeout and clear_req.
For the timeout case we take the lock after we grab a ref on the config,
but that isn't really necessary because we're safe to touch the cmd at
this point, so just move the order around.
For the clear_req cause this is initiated by the user, so again is safe.

[ Upstream commit 38b4fe320119859c11b1dc06f6b4987a16344fa1 ]
As soon as the netdev is registers, the kernel can start using the
interface. If the driver connects the MAC to the PHY after the netdev
is registered, there is a race condition where the interface can be
opened without having the PHY connected.
Change the order to close this race condition.

[ Upstream commit a904a0693c189691eeee64f6c6b188bd7dc244e9 ]
Historically linux tried to stick to RFC 791, 1122, 2003
for IPv4 ID field generation.
RFC 6864 made clear that no matter how hard we try,
we can not ensure unicity of IP ID within maximum
lifetime for all datagrams with a given source
address/destination address/protocol tuple.
Linux uses a per socket inet generator (inet_id), initialized
at connection startup with a XOR of 'jiffies' and other
fields that appear clear on the wire.
Thiemo Nagel pointed that this strategy is a privacy
concern as this provides 16 bits of entropy to fingerprint
devices.
Let's switch to a random starting point, this is just as
good as far as RFC 6864 is concerned and does not leak
anything critical.

Since it became possible for the DSA core to use a CPU port different
than 8, our bcm_sf2_imp_setup() function was broken because it assumes
that registers are applicable to port 8. In particular, the port's MAC
is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
bits if we are not configured for port 8.

[ Upstream commit b7265a0df82c1716bf788096217083ed65a8bb14 ]
The devlink parameter "acl_region_rehash_interval" is a runtime
parameter whose value is stored in a dynamically allocated memory. While
reloading the driver, this memory is freed and then allocated again. A
use-after-free might happen if during this time frame someone tries to
retrieve its value.
Since commit 070c63f20f6c ("net: devlink: allow to change namespaces
during reload") the use-after-free can be reliably triggered when
reloading the driver into a namespace, as after freeing the memory (via
reload_down() callback) all the parameters are notified.
Fix this by unpublishing and then re-publishing the parameters during
reload.
Fixes: 98bbf70c1c41 ("mlxsw: spectrum: add "acl_region_rehash_interval" devlink param")
Fixes: 7c62cfb8c574 ("devlink: publish params only after driver init is done")

commit abe57073d08c13b95a46ccf48cc9dc957d5c6fdb upstream.
When the client hits reconnect it iterates over the mid
pending queue marking entries for retry and moving them
to a temporary list to issue callbacks later without holding
GlobalMid_Lock. In the same time there is no guarantee that
mids can't be removed from the temporary list or even
freed completely by another thread. It may cause a temporary
list corruption:

Fix this by obtaining extra references for mids being retried
and marking them as MID_DELETED which indicates that such a mid
has been dequeued from the pending list.
Also move mid cleanup logic from DeleteMidQEntry to
_cifs_mid_q_entry_release which is called when the last reference
to a particular mid is put. This allows to avoid any use-after-free
of response buffers.
The patch needs to be backported to stable kernels. A stable tag
is not mentioned below because the patch doesn't apply cleanly
to any actively maintained stable kernel.

commit 7b2db65b59c30d58c129d3c8b2101feca686155a upstream.
24 bits is supported in all modes and 16 bit only when the codec is slave
and the DAI is set to RIGHT_J.
Remove the unsupported sample format.

[ Upstream commit d4e4fdf9e4a27c87edb79b1478955075be141f67 ]
In rtnl_net_notifyid(), we certainly can't pass a null GFP flag to
rtnl_notify(). A GFP_KERNEL flag would be fine in most circumstances,
but there are a few paths calling rtnl_net_notifyid() from atomic
context or from RCU critical sections. The later also precludes the use
of gfp_any() as it wouldn't detect the RCU case. Also, the nlmsg_new()
call is wrong too, as it uses GFP_KERNEL unconditionally.
Therefore, we need to pass the GFP flags as parameter and propagate it
through function calls until the proper flags can be determined.
In most cases, GFP_KERNEL is fine. The exceptions are:
* openvswitch: ovs_vport_cmd_get() and ovs_vport_cmd_dump()
indirectly call rtnl_net_notifyid() from RCU critical section,
* rtnetlink: rtmsg_ifinfo_build_skb() already receives GFP flags as
parameter.
Also, in ovs_vport_cmd_build_info(), let's change the GFP flags used
by nlmsg_new(). The function is allowed to sleep, so better make the
flags consistent with the ones used in the following
ovs_vport_cmd_fill_info() call.
Found by code inspection.

[ Upstream commit a793183caa9afae907a0d7ddd2ffd57329369bf5 ]
KCSAN reported a data-race in udp_set_dev_scratch() [1]
The issue here is that we must not write over skb fields
if skb is shared. A similar issue has been fixed in commit
89c22d8c3b27 ("net: Fix skb csum races when peeking")
While we are at it, use a helper only dealing with
udp_skb_scratch(skb)->csum_unnecessary, as this allows
udp_set_dev_scratch() to be called once and thus inlined.

As reported in [0] at least one RTL8168dp version has problems
establishing a link. This chip version has an integrated RTL8211b PHY,
however the chip seems to report a wrong PHY ID, resulting in a wrong

Work around this issue by adding a hook to r8168dp_2_mdio_read()
for returning the correct PHY ID.

[ Upstream commit 9df86bdb6746d7fcfc2fda715f7a7c3d0ddb2654 ]
When CQE compression is enabled, compressed CQEs use the following
structure: a title is followed by one or many blocks, each containing 8
mini CQEs (except the last, which may contain fewer mini CQEs).
Due to NAPI budget restriction, a complete structure is not always
parsed in one NAPI run, and some blocks with mini CQEs may be deferred
to the next NAPI poll call - we have the mlx5e_decompress_cqes_cont call
in the beginning of mlx5e_poll_rx_cq. However, if the budget is
extremely low, some blocks may be left even after that, but the code
that follows the mlx5e_decompress_cqes_cont call doesn't check it and
assumes that a new CQE begins, which may not be the case. In such cases,
random memory corruptions occur.
An extremely low NAPI budget of 8 is used when busy_poll or busy_read is
active.
This commit adds a check to make sure that the previous compressed CQE
has been completely parsed after mlx5e_decompress_cqes_cont, otherwise
it prevents a new CQE from being fetched in the middle of a compressed
CQE.
This commit fixes random crashes in __build_skb, __page_pool_put_page
and other not-related-directly places, that used to happen when both CQE
compression and busy_poll/busy_read were enabled.

[ Upstream commit 301428ea3708188dc4a243e6e6b46c03b46a0fbc ]
If a nonblocking socket is immediately closed after connect(),
the connect worker may not have started. This results in a refcount
problem, since sock_hold() is called from the connect worker.
This patch moves the sock_hold in front of the connect worker
scheduling.

commit 55667441c84fa5e0911a0aac44fb059c15ba6da2 upstream.
UDP IPv6 packets auto flowlabels are using a 32bit secret
(static u32 hashrnd in net/core/flow_dissector.c) and
apply jhash() over fields known by the receivers.
Attackers can easily infer the 32bit secret and use this information
to identify a device and/or user, since this 32bit secret is only
set at boot time.
Really, using jhash() to generate cookies sent on the wire
is a serious security concern.
Trying to change the rol32(hash, 16) in ip6_make_flowlabel() would be
a dead end. Trying to periodically change the secret (like in sch_sfq.c)
could change paths taken in the network for long lived flows.
Let's switch to siphash, as we did in commit df453700e8d8
("inet: switch IP ID generator to siphash")
Using a cryptographically strong pseudo random function will solve this
privacy issue and more generally remove other weak points in the stack.
Packet schedulers using skb_get_hash_perturb() benefit from this change.
Fixes: b56774163f99 ("ipv6: Enable auto flow labels by default")
Fixes: 42240901f7c4 ("ipv6: Implement different admin modes for automatic flow labels")
Fixes: 67800f9b1f4e ("ipv6: Call skb_get_hash_flowi6 to get skb->hash in ip6_make_flowlabel")

[ Upstream commit a7fa12d15855904aff1716e1fc723c03ba38c5cc ]
To corrupt a GSO frame we first perform segmentation. We then
proceed using the first segment instead of the full GSO skb and
requeue the rest of the segments as separate packets.
If there are any issues with processing the first segment we
still want to process the rest, therefore we jump to the
finish_segs label.
Commit 177b8007463c ("net: netem: fix backlog accounting for
corrupted GSO frames") started using the pointer to the first
segment in the "rest of segments processing", but as mentioned
above the first segment may had already been freed at this point.
Backlog corrections for parent qdiscs have to be adjusted.
Fixes: 177b8007463c ("net: netem: fix backlog accounting for corrupted GSO frames")

[ Upstream commit 2a06b8982f8f2f40d03a3daf634676386bd84dbc ]
Intel test robot reported a ~7% regression on TCP_CRR tests
that they bisected to the cited commit.
Indeed, every time a new TCP socket is created or deleted,
the atomic counter net->count is touched (via get_net(net)
and put_net(net) calls)
So cpus might have to reload a contended cache line in
net_hash_mix(net) calls.
We need to reorder 'struct net' fields to move @hash_mix
in a read mostly cache line.
We move in the first cache line fields that can be
dirtied often.
We probably will have to address in a followup patch
the __randomize_layout that was added in linux-4.13,
since this might break our placement choices.

From: Roger Quadros <[email protected]>
commit 163be6ff7739b12ff300d77897d340f661821da2 upstream.
If a gadget driver is in the pending drivers list, a UDC
becomes available and udc_bind_to_driver() fails, then it
gets deleted from the pending list.
i.e. list_del(&driver->pending) in check_pending_gadget_drivers().
Then if that gadget driver is unregistered,
usb_gadget_unregister_driver() does a list_del(&driver->pending)
again thus causing a page fault as that list entry has been poisoned
by the previous list_del().
Fix this by using list_del_init() instead of list_del() in
check_pending_gadget_drivers().
Test case:
- Make sure no UDC is available
- modprobe g_mass_storage file=wrongfile
- Load UDC driver so it becomes available
lun0: unable to open backing file: wrongfile
- modprobe -r g_mass_storage

[ Upstream commit 9669fffc1415bb0c30e5d2ec98a8e1c3a418cb9c ]
Thomas found that some forwarded packets would be stuck
in FQ packet scheduler because their skb->tstamp contained
timestamps far in the future.
We thought we addressed this point in commit 8203e2d844d3
("net: clear skb->tstamp in forwarding paths") but there
is still an issue when/if a packet needs to be fragmented.
In order to meet EDT requirements, we have to make sure all
fragments get the original skb->tstamp.
Note that this original skb->tstamp should be zero in
forwarding path, but might have a non zero value in
output path if user decided so.

[ Upstream commit 580a05f9d4ada3bfb689140d0efec1efdb8a48da ]
Currently, the num_msi_left means the vector numbers of NIC,
but if the PF supported RoCE, it contains the vector numbers
of NIC and RoCE(Not expected).
This may cause interrupts lost in some case, because of the
NIC module used the vector resources which belongs to RoCE.
This patch adds a new variable num_nic_msi to store the vector
numbers of NIC, and adjust the default TQP numbers and rss_size
according to the value of num_nic_msi.

[ Upstream commit f536dffc0b79738c3104af999318279dccbaa261 ]
For SMC sockets forced to fallback to TCP, the file is propagated
from the outer SMC to the internal TCP socket. When closing the SMC
socket, the internal TCP socket file pointer must be restored to the
original NULL value, otherwise memory leaks may show up (found with
CONFIG_DEBUG_KMEMLEAK).
The internal TCP socket is released in smc_clcsock_release(), which
calls __sock_release() function in net/socket.c. This calls the
needed iput(SOCK_INODE(sock)) only, if the file pointer has been reset
to the original NULL-value.

[ Upstream commit 88824e3bf29a2fcacfd9ebbfe03063649f0f3254 ]
We are calling the checksum helper after the dma_map_single()
call to map the packet. This is incorrect as the checksumming
code will touch the packet from the CPU. This means the cache
won't be properly flushes (or the bounce buffering will leave
us with the unmodified packet to DMA).
This moves the calculation of the checksum & vlan tags to
before the DMA mapping.
This also has the side effect of fixing another bug: If the
checksum helper fails, we goto "drop" to drop the packet, which
will not unmap the DMA mapping.

When commit 28b2e0d2cd13 ("net: phy: remove parameter new_link from
phy_mac_interrupt()") removed the new_link parameter it set the
phydev->link state from the MAC before invoking phy_mac_interrupt().
However, once commit 88d6272acaaa ("net: phy: avoid unneeded MDIO
reads in genphy_read_status") was added this initialization prevents
the proper determination of the connection parameters by the function
genphy_read_status().
This commit removes that initialization to restore the proper
functionality.

[ Upstream commit 7c3bebc3d8688b84795c11848c314a2fbfe045e0 ]
For adapters which support the SGE Doorbell Queue Timer facility,
we configured the Ethernet TX Queues to send CIDX Updates to the
Associated Ethernet RX Response Queue with CPL_SGE_EGR_UPDATE
messages to allow us to respond more quickly to the CIDX Updates.
But, this was adding load to PCIe Link RX bandwidth and,
potentially, resulting in higher CPU Interrupt load.
This patch requests the HW to deliver the CIDX updates to the TX
queue status page rather than generating an ingress queue message
(as an interrupt). With this patch, the load on RX bandwidth is
reduced and a substantial improvement in BW is noticed at lower
IO sizes.

Change current implementation to use the function mlx5e_port_linkspeed()

Newer versions of GCC (>= 9) demand that the size of the string to be
copied must be explicitly smaller than the size of the destination.
Thus, the NULL char has to be taken into account on strncpy.
This will avoid the following compiling error:

r0-r3 & r12 registers are saved & restored, before & after svc
respectively. Intention was to preserve those registers across thread to
handler mode switch.
On v7-M, hardware saves the register context upon exception in AAPCS
complaint way. Restoring r0-r3 & r12 is done from stack location where
hardware saves it, not from the location on stack where these registers
were saved.
To clarify, on stm32f429 discovery board:
1. before svc, sp - 0x90009ff8
2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b
3. upon svc, h/w decrements sp by 32 & pushes registers onto stack
4. after svc, sp - 0x90009fd8
5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb
Above means r0-r3,r12 is not restored from the location where they are
saved, but since hardware pushes the registers onto stack, the registers
are restored correctly.
Note that during register saving to stack (step 2), it goes past
0x9000a000. And it seems, based on objdump, there are global symbols
residing there, and it perhaps can cause issues on a non-XIP Kernel
(on XIP, data section is setup later).
Based on the analysis above, manually saving registers onto stack is at
best no-op and at worst can cause data section corruption. Hence remove
storing of registers onto stack before svc.

HW doesn't allow flushing inactive pipes and raises an MERR interrupt
if you try to do so. Stop triggering the MERR interrupt in the
middle of a commit by calling drm_atomic_helper_commit_planes
with the ACTIVE_ONLY flag.

From: Doug Berger <[email protected]>
[ Upstream commit 25382b991d252aed961cd434176240f9de6bb15f ]
The EPHY integrated into the 40nm Set-Top Box devices can falsely
detect energy when connected to a disabled peer interface. When the
peer interface is enabled the EPHY will detect and report the link
as active, but on occasion may get into a state where it is not
able to exchange data with the connected GENET MAC. This issue has
not been observed when the link parameters are auto-negotiated;
however, it has been observed with a manually configured link.
It has been empirically determined that issuing a soft reset to the
EPHY when energy is detected prevents it from getting into this bad
state.

All the kcontrol put() functions are currently returning 0 when
successful. This does not go well with alsamixer as it does
not seem to get notified on SND_CTL_EVENT_MASK_VALUE callbacks
when values change for (some of) the sof kcontrols.
This patch fixes that by returning true for volume, switch
and enum type kcontrols when values do change in put().

[ Upstream commit d46b0da7a33dd8c99d969834f682267a45444ab3 ]
There's a deadlock that is possible and can easily be seen with
a test where multiple readers open/read/close of the same file
and a disruption occurs causing reconnect. The deadlock is due
a reader thread inside cifs_strict_readv calling down_read and
obtaining lock_sem, and then after reconnect inside
cifs_reopen_file calling down_read a second time. If in
between the two down_read calls, a down_write comes from
another process, deadlock occurs.

OR

cifs_reopen_file()

Fix the above by changing all down_write(lock_sem) calls to
down_write_trylock(lock_sem)/msleep() loop, which in turn
makes the second down_read call benign since it will never
block behind the writer while holding lock_sem.

This was preceded by us timing out everything and shutting down the
sockets for the device. The problem is we had a request in the queue at
the same time, so we completed the request twice. This can actually
happen in a lot of cases, we fail to get a ref on our config, we only
have one connection and just error out the command, etc.
Fix this by checking cmd->status in nbd_read_stat. We only change this
under the cmd->lock, so we are safe to check this here and see if we've
already error'ed this command out, which would indicate that we've
completed it as well.

[ Upstream commit 8424312516e5d9baeeb0a95d0e4523579b7aa395 ]
On a system without Single VMOVP support (say GITS_TYPER.VMOVP == 0),
we will map vPEs only on ITSs that will actually control interrupts
for the given VM. And when moving a vPE, the VMOVP command will be
issued only for those ITSs.
But when issuing VMOVPs we seemed fail to present the exact ITSList
to ITSs who are actually included in the synchronization operation.
The its_list_map we're currently using includes all ITSs in the system,
even though some of them don't have the corresponding vPE mapping at all.
Introduce get_its_list() to get the per-VM its_list_map, to indicate
which ITSs have vPE mappings for the given VM, and use this map as
the expected ITSList when building VMOVP. This is hopefully a performance
gain not to do some synchronization with those unsuspecting ITSs.
And initialize the whole command descriptor to zero at beginning, since
the seq_num and its_list should be RES0 when GITS_TYPER.VMOVP == 1.

[ Upstream commit 0b834ba00ab5337e938c727e216e1f5249794717 ]
Since commit af4d768ad28c ("net/ipv4: Add support for specifying metric
of connected routes"), when updating an IP address with a different metric,
the associated connected route is updated, too.
Still, the mentioned commit doesn't handle properly some corner cases:
$ ip addr add dev eth0 192.168.1.0/24
$ ip addr add dev eth0 192.168.2.1/32 peer 192.168.2.2
$ ip addr add dev eth0 192.168.3.1/24
$ ip addr change dev eth0 192.168.1.0/24 metric 10
$ ip addr change dev eth0 192.168.2.1/32 peer 192.168.2.2 metric 10
$ ip addr change dev eth0 192.168.3.1/24 metric 10
$ ip -4 route
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.0
192.168.2.2 dev eth0 proto kernel scope link src 192.168.2.1
192.168.3.0/24 dev eth0 proto kernel scope link src 192.168.2.1 metric 10
Only the last route is correctly updated.
The problem is the current test in fib_modify_prefix_metric():
if (!(dev->flags & IFF_UP) ||
ifa->ifa_flags & (IFA_F_SECONDARY | IFA_F_NOPREFIXROUTE) ||
ipv4_is_zeronet(prefix) ||
prefix == ifa->ifa_local || ifa->ifa_prefixlen == 32)
Which should be the logical 'not' of the pre-existing test in
fib_add_ifaddr():
if (!ipv4_is_zeronet(prefix) && !(ifa->ifa_flags & IFA_F_SECONDARY) &&
(prefix != addr || ifa->ifa_prefixlen < 32))
To properly negate the original expression, we need to change the last
logical 'or' to a logical 'and'.

[ Upstream commit 2558b3b1b11a1b32b336be2dd0aabfa6d35ddcb5 ]
The RockPro64 schematics [1], [2] show that the rk3399 EMMC_STRB pin is
connected to the RESET pin instead of the DATA_STROBE pin of the eMMC module.
So the data strobe cannot be used for its intended purpose on this board,
and so the HS400 eMMC mode is not functional. Limit the controller to HS200.

According to the RockPro64 schematic [1] the rk3399 sdmmc controller is
connected to a microSD (TF card) slot. Remove the cap-mmc-highspeed
property of the sdmmc controller, since no mmc card can be connected here.

Prior to this patch, the amount of counters guaranteed per VF in the
resource tracker was MLX4_VF_COUNTERS_PER_PORT * MLX4_MAX_PORTS. It was
set regardless if the VF was single or dual port.
This caused several VFs to have no guaranteed counters although the
system could satisfy their request.
The fix is to dynamically guarantee counters, based on each VF
specification.

[ Upstream commit ca2347190adb5e4eece73a2b16e96e651c46246b ]
In case of WM1811 device there are currently being registered controls
referring to registers not existing on that device.
It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2
Volume" controls was failing during ALSA state restoring at boot time:
"amixer: Mixer hw:0 load error: Device or resource busy"
Reading some registers through I2C was failing with EBUSY error and
indeed these registers were not available according to the datasheet.
To fix this controls not available on WM1811 are moved to a separate
array and registered only for WM8994 and WM8958.
There are some further differences between WM8994 and WM1811,
e.g. registers 603h, 604h, 605h, which are not covered in this patch.

If rockchip_pcm_platform_register() fails, e.g. upon deferring to wait
for an absent DMA channel, we return without disabling RPM, which makes
subsequent re-probe attempts scream with errors about the unbalanced
enable. Don't do that.

[ Upstream commit 57ff2df1b952c7934d7b0e1d3a2ec403ec76edec ]
Keeping the IRQ chip definition static shares it with multiple instances of
the GPIO chip in the system. This is bad and now we get this warning from
GPIO library:
"detected irqchip that is shared with multiple gpiochips: please fix the driver."
Hence, move the IRQ chip definition from being driver static into the struct
intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.

passthrough_parse_cdb() - used by TCMU and PSCSI - attepts to reset the LUN
field of SCSI-2 CDBs (bits 5,6,7 of byte 1). The current code is wrong as
for newer commands not having the LUN field it overwrites relevant command
bits (e.g. for SECURITY PROTOCOL IN / OUT). We think this code was
unnecessary from the beginning or at least it is no longer useful. So we
remove it entirely.

[ Upstream commit 0990c5e7573098117c69651821647c228483e31b ]
The RockPro64 schematic [1] page 18 states a min voltage of 0.8V and a
max voltage of 1.4V for the VDD_LOG pwm regulator. However, there is an
additional note that the pwm parameter needs to be modified.
>From the schematics a voltage range of 0.8V to 1.7V can be calculated.
Additional voltage measurements on the board show that this fix indeed
leads to the correct voltage, while without this fix the voltage was set
too high.

From: Ranjani Sridharan <[email protected]>
[ Upstream commit 43b2ab9009b13bfff47fcc1893de9244b39bdd54 ]
There is a known issue on some Intel platforms which causes
pause/release to run into xrun's during capture usecases.
The suggested workaround to address the issue is to
disable the entry of lower power L1 state in the physical
DMI link when there is a capture stream open.
