[ Upstream commit bc519d9574618e47a0c788000fb78da95e18d953 ]
The BCM2835 AUX SPI has a shared interrupt line (with AUX UART).
Downstream fixes this with an AUX irqchip to demux the IRQ sources and a
DT change which breaks compatibility with older kernels. The AUX irqchip
was already rejected for upstream[1] and the DT change would break
working systems if the DTB is updated to a newer one. The latter issue
was brought to my attention by Alex Graf.
The root cause however is a bug in the shared handler. Shared handlers
must check that interrupts are actually enabled before servicing the
interrupt. Add a check that the TXEMPTY or IDLE interrupts are enabled.

[ Upstream commit 9aa169213d1166d30ae357a44abbeae93459339d ]
When commit [1] was added, SGID was queried to derive the SMAC address.
Then, later on during a refactor [2], SMAC was no longer needed. However,
the now useless GID query remained. Then during additional code changes
later on, the GID query was being done in such a way that it caused iWARP
queries to start breaking. Remove the useless GID query and resolve the
iWARP breakage at the same time.
This is discussed in [3].

[ Upstream commit b03bcde962606d2ee59a4e9dd470db9ad53c5418 ]
When the kernel was compiled using the UBSAN option,
we saw the following stack trace:
[ 1184.827917] UBSAN: Undefined behaviour in drivers/infiniband/hw/mlx4/mr.c:349:27
[ 1184.828114] signed integer overflow:
[ 1184.828247] -2147483648 - 1 cannot be represented in type 'int'
The problem was caused by calling round_up in procedure
mlx4_ib_umem_calc_optimal_mtt_size (on line 349, as noted in the stack
trace) with the second parameter (1 << block_shift) (which is an int).
The second parameter should have been (1ULL << block_shift) (which
is an unsigned long long).
(1 << block_shift) is treated by the compiler as an int (because 1 is
an integer).
Now, local variable block_shift is initialized to 31.
If block_shift is 31, 1 << block_shift is 1 << 31 = 0x80000000=-214748368.
This is the most negative int value.
Inside the round_up macro, there is a cast applied to ((1 << 31) - 1).
However, this cast is applied AFTER ((1 << 31) - 1) is calculated.
Since (1 << 31) is treated as an int, we get the negative overflow
identified by UBSAN in the process of calculating ((1 << 31) - 1).
The fix is to change (1 << block_shift) to (1ULL << block_shift) on
line 349.

[ Upstream commit e9777ad4399c26c70318c4945f94efac2ed95391 ]
When allocating device data, if there's an allocation failure, the
already allocated memory won't be freed such as per-cpu counters.
Fix memory leaks in exception path by creating a common reentrant
clean up function hfi1_clean_devdata() to be used at driver unload
time and device data allocation failure.
To accomplish this, free_platform_config() and clean_up_i2c() are
changed to be reentrant to remove dependencies when they are called
in different order. This helps avoid NULL pointer dereferences
introduced by this patch if those two functions weren't reentrant.
In addition, set dd->int_counter, dd->rcv_limit,
dd->send_schedule and dd->tx_opstats to NULL after they're freed in
hfi1_clean_devdata(), so that hfi1_clean_devdata() is fully reentrant.

[ Upstream commit 1a2f474d328f292ee706414824ec4ca690cdf5ba ]
If the I2C adapter that the PD controller is attached to
does not support SMBus protocol, the driver needs to handle
block reads separately. The first byte returned in block
read protocol will show the total number of bytes. It needs
to be stripped away.
This is handled separately in the driver only because right
now we have no way of requesting the used protocol with
regmap-i2c. This is in practice a workaround for what is
really a problem in regmap-i2c. The other option would have
been to register custom regmap, or not use regmap at all,
however, since the solution is very simple, I choose to use
it in this case for convenience. It is easy to remove once
we figure out how to handle this kind of cases in
regmap-i2c.

[ Upstream commit 83b9dc11312f48a561594a895672abb6cb2a2250 ]
When we dropped the custom Linux GPIO translation it resulted that the
IRQ numbers changed slightly as well. Normally this would be fine
because everyone is expected to use controller relative GPIO numbers and
ACPI GpioIo/GpioInt resources. However, there is a certain set of
Intel_Strago based Chromebooks where i8042 keyboard controller IRQ
number is hardcoded be 182 (this is corrected with newer coreboot but
the older ones still have the hardcoded Linux IRQ number). Because of
this hardcoded IRQ number keyboard on those systems accidentally broke
again.
Fix this by iteratively associating IRQ descriptors to the chip irqdomain
so that there are no gaps on those systems. Other systems are not
affected.

[ Upstream commit 068bdb67ef74df0ad1627b7247a163e3e252ac11 ]
The automatic update mechanism will trigger an update if the
info block CRCs are different between maxtouch configuration
file (maxtouch.cfg) and chip.
The driver compared the CRCs without retrieving the chip CRC,
resulting always in a failure and firmware flashing action
triggered. Fix this issue by retrieving the chip info block
CRC before the check.
Note that this solution has the benefit that by reading the
information block and the object table into a contiguous region
of memory, we can verify the checksum at probe time. This means
we make sure that we are indeed talking to a chip that supports
object protocol correctly.
Using this patch on a kevin chromebook, the touchscreen and
touchpad drivers are able to match the CRC:

[ Upstream commit db82476f37413eaeff5f836a9d8b022d6544accf ]
Currently, the kernel protects access to the agent ID allocator on a per
port basis using a spinlock, so it is impossible for two apps/threads on
the same port to get the same TID, but it is entirely possible for two
threads on different ports to end up with the same TID.
As this can be confusing (regardless of it being legal according to the
IB Spec 1.3, C13-18.1.1, in section 13.4.6.4 - TransactionID usage),
and as the rdma-core user space API for /dev/umad devices implies unique
TIDs even across ports, make the TID an atomic type so that no two
allocations, regardless of port number, will be the same.

[ Upstream commit 9fd4350ba8953804f05215999e11a6cfb7b41f2b ]
When skb is sent, it will pass the following functions in soft roce.
rxe_send [rdma_rxe]
ip_local_out
__ip_local_out
ip_output
ip_finish_output
ip_finish_output2
dev_queue_xmit
__dev_queue_xmit
dev_hard_start_xmit
In the above functions, if error occurs in the above functions or
iptables rules drop skb after ip_local_out, kfree_skb will be called.
So it is not necessary to call kfree_skb in soft roce module again.
Or else crash will occur.
The steps to reproduce:
server client
--------- ---------
|1.1.1.1|<----rxe-channel--->|1.1.1.2|
--------- ---------
On server: rping -s -a 1.1.1.1 -v -C 10000 -S 512
On client: rping -c -a 1.1.1.1 -v -C 10000 -S 512
The kernel configs CONFIG_DEBUG_KMEMLEAK and
CONFIG_DEBUG_OBJECTS are enabled on both server and client.
When rping runs, run the following command in server:
iptables -I OUTPUT -p udp --dport 4791 -j DROP
Without this patch, crash will occur.

w/o RXE_START_MASK, the last_psn of IB_OPCODE_RC_SEND_ONLY_INV
will not be updated in update_wqe_psn, and the corresponding
wqe will not be acked in rxe_completer due to its last_psn is
zero. Finally, the other wqe will also not be able to be acked,
because the wqe of IB_OPCODE_RC_SEND_ONLY_INV with last_psn 0
is still there. This causes large amount of io timeout when
nvmeof is over rxe.

[ Upstream commit 2918c1a900252b4a0c730715ec205437c7daf79d ]
There are few issues with validation of netdevice and listen id lookup
for IB (IPoIB) while processing incoming CM request as below.
1. While performing lookup of bind_list in cma_ps_find(), net namespace
of the netdevice can get deleted in cma_exit_net(), resulting in use
after free access of idr and/or net namespace structures.
This lookup occurs from the workqueue context (and not userspace
context where net namespace is always valid).
CPU0 CPU1
==== ====
bind_list = cma_ps_find();
move netdevice to new namespace
delete net namespace
cma_exit_net()
idr_destroy(idr);
[..]
cma_find_listener(bind_list, ..);
2. While netdevice is validated for IP address in given net namespace,
netdevice's net namespace and/or ifindex can change in
cma_get_net_dev() and cma_match_net_dev().
Above issues are overcome by using rcu lock along with netdevice
UP/DOWN state as described below.
When a net namespace is getting deleted, netdevice is closed and
shutdown before moving it back to init_net namespace.
change_net_namespace() synchronizes with any existing use of netdevice
before changing the netdev properties such as net or ifindex.
Once netdevice IFF_UP flags is cleared, such fields are not guaranteed
to be valid.
Therefore, rcu lock along with netdevice state check ensures that,
while route lookup and cm_id lookup is in progress, netdevice of
interest won't migrate to any other net namespace.
This ensures that associated net namespace of netdevice won't get
deleted while rcu lock is held for netdevice which is in IFF_UP state.

There is an issue(Errata Ref#226) that the SATA can not be

error log:
ata1.15: PMP product ID mismatch

ata1.15: Port Multiplier vendor mismatch '0x1b4b'!='0x0'
ata1.15: PMP revalidation failed (errno=-19)
After debugging, the reason is found that the value Port-x
FIS-based Switching Control(PxFBS@0x40) become wrong.
According to design, the bits[11:8, 0] of register PxFBS
are cleared when Port Command and Status (0x18) bit[0]
changes its value from 1 to 0, i.e. falling edge of Port
Command and Status bit[0] sends PULSE that resets PxFBS
bits[11:8; 0].
So it needs a mvebu SATA WA to save the port PxFBS register
before PxCMD ST write and restore it afterwards.
This patch implements the WA in a separate function of
ahci_mvebu_stop_engine to override ahci_stop_gngine.

When Qav mode is enabled, queue 0 should be kept on Stream Reservation
mode. From the i210 datasheet, section 8.12.19:
"Note: Queue0 QueueMode must be set to 1b when TransmitMode is set to
Qav." ("QueueMode 1b" represents the Stream Reservation mode)
The solution is to give queue 0 the all the credits it might need, so
it has priority over queue 1.
A situation where this can happen is when cbs is "installed" only on
queue 1, leaving queue 0 alone. For example:
$ tc qdisc replace dev enp2s0 handle 100: parent root mqprio num_tc 3 \
