serial: amba-pl011: avoid SBSA UART accessing DMACR register

[ Upstream commit 94cdb9f33698478b0e7062586633c42c6158a786 ]

Chapter "B Generic UART" in "ARM Server Base System Architecture" [1]
documentation describes a generic UART interface. Such generic UART
does not support DMA. In current code, sbsa_uart_pops and
amba_pl011_pops share the same stop_rx operation, which will invoke
pl011_dma_rx_stop, leading to an access of the DMACR register. This
commit adds a using_rx_dma check in pl011_dma_rx_stop to avoid the
access to DMACR register for SBSA UARTs which does not support DMA.

When the kernel enables DMA engine with "CONFIG_DMA_ENGINE=y", Linux
SBSA PL011 driver will access PL011 DMACR register in some functions.
For most real SBSA Pl011 hardware implementations, the DMACR write
behaviour will be ignored. So these DMACR operations will not cause
obvious problems. But for some virtual SBSA PL011 hardware, like Xen
virtual SBSA PL011 (vpl011) device, the behaviour might be different.
Xen vpl011 emulation will inject a data abort to guest, when guest is
accessing an unimplemented UART register. As Xen VPL011 is SBSA
compatible, it will not implement DMACR register. So when Linux SBSA
PL011 driver access DMACR register, it will get an unhandled data abort
fault and the application will get a segmentation fault:

USB: gadget: Fix use-after-free during usb config switch

[ Upstream commit afdc12887f2b2ecf20d065a7d81ad29824155083 ]

In the process of switching USB config from rndis to other config,
if the hardware does not support the ->pullup callback, or the
hardware encounters a low probability fault, both of them may cause
the ->pullup callback to fail, which will then cause a system panic
(use after free).

The gadget drivers sometimes need to be unloaded regardless of the
hardware's behavior.

extcon: usbc-tusb320: Update state on probe even if no IRQ pending

[ Upstream commit 581c848b610dbf3fe1ed4d85fd53d0743c61faba ]

Currently this driver triggers extcon and typec state update in its
probe function, to read out current state reported by the chip and
report the correct state to upper layers. This synchronization is
performed correctly, but only in case the chip indicates a pending
interrupt in reg09 register.

This fails to cover the situation where all interrupts reported by
the chip were already handled by Linux before reboot, then the system
rebooted, and then Linux starts again. In this case, the TUSB320 no
longer reports any interrupts in reg09, and the state update does not
perform any update as it depends on that interrupt indication.

Fix this by turning tusb320_irq_handler() into a thin wrapper around
tusb320_state_update_handler(), where the later now contains the bulk
of the code of tusb320_irq_handler(), but adds new function parameter
"force_update". The "force_update" parameter can be used by the probe
function to assure that the state synchronization is always performed,
independent of the interrupt indicated in reg09. The interrupt handler
tusb320_irq_handler() callback uses force_update=false to avoid state
updates on potential spurious interrupts and retain current behavior.

[ Upstream commit ffbe2feac59b37c8dc536727552b4f375e1b9aec ]

Probe for omap2430 glue layer is now broken for interrupt resources in
all cases.

Commit  239071064732 ("partially Revert "usb: musb: Set the DT node on the
child device"") broke probing for SoCs using ti-sysc interconnect target
module as the dt node is not found.

Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from
DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as
the IRQ resources are no longer automatically populated from devicetree.

Let's fix the issues by calling device_set_of_node_from_dev() only if the
SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's
populate the resources manually as needed.

Note that once we have updated the SoCs to probe with proper devicetree
data in all cases, this is no longer needed. But doing that requires
patching both devicetree and SoC code, so let's fix the probe issues first.

('myfpga' is a simple 'uio_dmem_genirq' driver I wrote to test this)

The implementation of "uio_dmem_genirq" was based on "uio_pdrv_genirq" and
it is used in a similar manner to the "uio_pdrv_genirq" driver with respect
to interrupt configuration and handling. At the time "uio_dmem_genirq" was
introduced, both had the same implementation of the 'uio_info' handlers
irqcontrol() and handler(). Then commit 34cb27528398 ("UIO: Fix concurrency
issue"), which was only applied to "uio_pdrv_genirq", ended up making them
a little different. That commit, among other things, changed disable_irq()
to disable_irq_nosync() in the implementation of irqcontrol(). The
motivation there was to avoid a deadlock between irqcontrol() and
handler(), since it added a spinlock in the irq handler, and disable_irq()
waits for the completion of the irq handler.

By changing disable_irq() to disable_irq_nosync() in irqcontrol(), we also
avoid the sleeping-while-atomic bug that commit b74351287d4b ("uio: fix a
sleep-in-atomic-context bug in uio_dmem_genirq_irqcontrol()") was trying to
fix. Thus, this fixes the missing unlock in irqcontrol() by importing the
implementation of irqcontrol() handler from the "uio_pdrv_genirq" driver.
In the end, it reverts commit b74351287d4b ("uio: fix a
sleep-in-atomic-context bug in uio_dmem_genirq_irqcontrol()") and change
disable_irq() to disable_irq_nosync().

It is worth noting that this still does not address the concurrency issue
fixed by commit 34cb27528398 ("UIO: Fix concurrency issue"). It will be
addressed separately in the next commits.

Split out from commit 34cb27528398 ("UIO: Fix concurrency issue").

[ Upstream commit f38044e5ef58ad0346fdabd7027ea5c1e1a3b624 ]

iova_bitmap_set() doesn't consider the end of the page boundary when the
first bitmap page offset isn't zero, and wrongly changes the consecutive
page right after. Consequently this leads to missing dirty pages from
reported by the device as seen from the VMM.

The current logic iterates over a given number of base pages and clamps it
to the remaining indexes to iterate in the last page.  Instead of having to
consider extra pages to pin (e.g. first and extra pages), just handle the
first page as its own range and let the rest of the bitmap be handled as if
it was base page aligned.

This is done by changing iova_bitmap_mapped_remaining() to return PAGE_SIZE
- pgoff (on the first bitmap page), and leads to pgoff being set to 0 on
following iterations.

There are 2 ways to create IPoIB PKEY child interfaces:
1) Writing a PKEY to /sys/class/net/<ib parent interface>/create_child.
2) Using netlink with iproute.

While with sysfs the child interface has the same number of tx and
rx queues as the parent, with netlink there will always be 1 tx
and 1 rx queue for the child interface. That's because the
get_num_tx/rx_queues() netlink ops are missing and the default value
of 1 is taken for the number of queues (in rtnl_create_link()).

This change adds the get_num_tx/rx_queues() ops which allows for
interfaces with multiple queues to be created over netlink. This
constant only represents the max number of tx and rx queues on that

After the hns roce driver is loaded, if you modify the mac address of the

The reason for the error is that the gid being occupied will cause the
failure to modify the gid. The gid is occupied by the loopback QP used by
free mr. When the mac address is modified, the gid will change. If there
is a busy QP at this time, the gid will not be released and the
modification will fail. The QP of free mr is created using the ib
interface. The ib interface will add a reference count to the gid,
resulting in this error scenario.

Considering that free mr is solving a bug in HIP08, not an actual
business, it is not necessary to use ib interfaces.

The reset was never applied in the current implementation because Intel
Bridges owned by VMD are parentless. Internally, pci_reset_bus() applies
a reset to the parent of the PCI device supplied as argument, but in this
case it failed because there wasn't a parent.

In more detail, this change allows the VMD driver to enumerate NVMe devices
in pass-through configurations when guest reboots are performed. There was
an attempted to fix this, but later we discovered that the code inside
pci_reset_bus() wasn’t triggering secondary bus resets. Therefore, we
updated the parameters passed to it, and now NVMe SSDs attached to VMD
bridges are properly enumerated in VT-d pass-through scenarios.

crypto: tcrypt - Fix multibuffer skcipher speed test mem leak

[ Upstream commit 1aa33fc8d4032227253ceb736f47c52b859d9683 ]

In the past, the data for mb-skcipher test has been allocated
twice, that means the first allcated memory area is without
free, which may cause a potential memory leakage. So this
patch is to remove one allocation to fix this error.

[ Upstream commit 9c9ff300e0de07475796495d86f449340d454a0c ]

The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in
hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to
clean1 directly, which frees h and leaks the h->reply_map.

Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead
free h directly.
