5 years agoerofs: fix compile warnings when moving out include/trace/events/erofs.h

erofs: fix compile warnings when moving out include/trace/events/erofs.h

As Stephon reported [1], many compile warnings are raised when
moving out include/trace/events/erofs.h:

In file included from include/trace/events/erofs.h:8,
                 from <command-line>:

  ^~~~~~~~

That makes me very confused since most original EROFS tracepoint code
was taken from f2fs, and finally I found

commit 43c78d88036e ("kbuild: compile-test kernel headers to ensure they are self-contained")

It seems these warnings are generated from KERNEL_HEADER_TEST feature and
ext4/f2fs tracepoint files were in blacklist.

Anyway, let's fix these issues for KERNEL_HEADER_TEST feature instead
of adding to blacklist...

Gao Xiang [Thu, 22 Aug 2019 21:36:59 +0000 (05:36 +0800)]
erofs: move erofs out of staging

EROFS filesystem has been merged into linux-staging for a year.

EROFS is designed to be a better solution of saving extra storage
space with guaranteed end-to-end performance for read-only files
with the help of reduced metadata, fixed-sized output compression
and decompression inplace technologies.

In the past year, EROFS was greatly improved by many people as
a staging driver, self-tested, betaed by a large number of our
internal users, successfully applied to almost all in-service
HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable
enough to be moved out of staging.

EROFS is a self-contained filesystem driver. Although there are
still some TODOs to be more generic, we have a dedicated team
actively keeping on working on EROFS in order to make it better
with the evolution of Linux kernel as the other in-kernel filesystems.

As Pavel suggested, it's better to do as one commit since git
can do moves and all histories will be saved in this way.

Let's promote it from staging and enhance it more actively as
a "real" part of kernel for more wider scenarios!

a special section (e71a4e1bebaf7 ("arm64: ftrace: add support for far

no cache maintenance was needed. However, later in be0f272bfc83 ("arm64:

to output the trampoline instructions directly into the PLT entry but,
unfortunately, the necessary cache maintenance was overlooked.

Add a call to __flush_icache_range() after writing the new trampoline
instructions but before patching in the branch to the trampoline.

ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_term

`check_input_term` recursively calls itself with input from
device side (e.g., uac_input_terminal_descriptor.bCSourceID)
as argument (id). In `check_input_term`, if `check_input_term`
is called with the same `id` argument as the caller, it triggers
endless recursive call, resulting kernel space stack overflow.

This patch fixes the bug by adding a bitmap to `struct mixer_build`
to keep track of the checked ids and stop the execution if some id
has been checked (similar to how parse_audio_unit handles unitid

This patch may fix two issues:

First, when IOSQE_IO_DRAIN set, the next IOs need to be inserted into
defer list to delay execution, but link io will be actively scheduled to
run by calling io_queue_sqe.

Second, when multiple LINK_IOs are inserted together with defer_list,
the LINK_IO is no longer keep order.

   |-------------|
   |   LINK_IO   |      ----> insert to defer_list  -----------

io_uring: fix manual setup of iov_iter for fixed buffers

Commit bd11b3a391e3 ("io_uring: don't use iov_iter_advance() for fixed
buffers") introduced an optimization to avoid using the slow
iov_iter_advance by manually populating the iov_iter iterator in some
cases.

However, the computation of the iterator count field was erroneous: The
first bvec was always accounted for an extent of page size even if the
bvec length was smaller.

In consequence, some I/O operations on fixed buffers were unable to
operate on the full extent of the buffer, consistently skipping some
bytes at the end of it.

Fix b) by calling the respective cleanup functions during

5 years agoUSB: serial: option: Add Motorola modem UARTs
Tony Lindgren [Thu, 15 Aug 2019 08:26:02 +0000 (01:26 -0700)]
USB: serial: option: Add Motorola modem UARTs

On Motorola Mapphone devices such as Droid 4 there are five USB ports
that do not use the same layout as Gobi 1K/2K/etc devices listed in
qcserial.c. So we should use qcaux.c or option.c as noted by
Dan Williams <dan.j.williams@intel.com>.

As the Motorola USB serial ports have an interrupt endpoint as shown
with lsusb -v, we should use option.c instead of qcaux.c as pointed out
by Johan Hovold <johan@kernel.org>.

The ff/ff/ff interfaces seem to always be UARTs on Motorola devices.
For the other interfaces, class 0x0a (CDC Data) should not in general
be added as they are typically part of a multi-interface function as
noted earlier by Bjørn Mork <bjorn@mork.no>.

However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a
class is only used for flashing the modem firmware, and there are no
other interfaces. So I've added that too with more details below as it
works just fine.

The ttyUSB ports on Droid 4 are:

ttyUSB0 DIAG, CQDM-capable
ttyUSB1 MUX or NMEA, no response
ttyUSB2 MUX or NMEA, no response
ttyUSB3 TCMD
ttyUSB4 AT-capable

The ttyUSB0 is detected as QCDM capable by ModemManager. I think
it's only used for debugging with ModemManager --debug for sending
custom AT commands though. ModemManager already can manage data
connection using the USB QMI ports that are already handled by the
qmi_wwan.c driver.

To enable the MUX or NMEA ports, it seems that something needs to be
done additionally to enable them, maybe via the DIAG or TCMD port.
It might be just a NVRAM setting somewhere, but I have no idea what
NVRAM settings may need changing for that.

The TCMD port seems to be a Motorola custom protocol for testing
the modem and to configure it's NVRAM and seems to work just fine
based on a quick test with a minimal tcmdrw tool I wrote.

The voice modem AT-capable port seems to provide only partial
support, and no PM support compared to the TS 27.010 based UART
wired directly to the modem.

The UARTs added with this change are the same product IDs as the
Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't
have any mdm9600 based devices, so I have only tested these on
mdm6600 based droid 4.

Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android
Linux kernel driver moto_flashqsc.c just seems to change the
port->bulk_out_size to 8K from the default. And is only used for
flashing the modem firmware it seems.

I've verified that flashing the modem with signed firmware works just
fine with the option driver after manually toggling the GPIO pins, so
I've added droid 4 modem flashing mode to the option driver. I've not
added the other devices listed in moto_flashqsc.c in case they really
need different port->bulk_out_size. Those can be added as they get
tested to work for flashing the modem.

After this patch the output of /sys/kernel/debug/usb/devices has
the following for normal 22b8:2a70 mode including the related qmi_wwan

drm/nouveau: Only recalculate PBN/VCPI on mode/connector changes

I -thought- I had fixed this entirely, but it looks like that I didn't
test this thoroughly enough as we apparently still make one big mistake
with nv50_msto_atomic_check() - we don't handle the following scenario:

* CRTC #1 has n VCPI allocated to it, is attached to connector DP-4
  which is attached to encoder #1. enabled=y active=n
* CRTC #1 is changed from DP-4 to DP-5, causing:
  * DP-4 crtc=#1→NULL (VCPI n→0)
  * DP-5 crtc=NULL→#1
  * CRTC #1 steals encoder #1 back from DP-4 and gives it to DP-5
  * CRTC #1 maintains the same mode as before, just with a different
    connector
* mode_changed=n connectors_changed=y
  (we _SHOULD_ do VCPI 0→n here, but don't)

Once the above scenario is repeated once, we'll attempt freeing VCPI
from the connector that we didn't allocate due to the connectors
changing, but the mode staying the same. Sigh.

Since nv50_msto_atomic_check() has broken a few times now, let's rethink
things a bit to be more careful: limit both VCPI/PBN allocations to
mode_changed || connectors_changed, since neither VCPI or PBN should
ever need to change outside of routing and mode changes.

Changes since v1:
* Fix accidental reversal of clock and bpp arguments in

dt-bindings: pinctrl: stm32: Fix 'st,syscfg' schema

The proper way to add additional contraints to an existing json-schema
is using 'allOf' to reference the base schema. Using just '$ref' doesn't
work. Fix this for the 'st,syscfg' property.
