[PATCH 5.10 02/38] HID: quirks: Set INCREMENT_USAGE_ON_DUPLICATE for Saitek X65

[Greg Kroah-Hartman]

From: Nirenjan Krishnan <nirenjan@gmail.com>

[ Upstream commit 25bdbfbb2d8331a67824dd03d0087e9c98835f3a ]

The Saitek X65 joystick has a pair of axes that were used as mouse
pointer controls by the Windows driver. The corresponding usage page is
the Game Controls page, which is not recognized by the generic HID
driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes
the second axis get mapped to ABS_MISC+1, and therefore made available
separately.

[PATCH 5.10 03/38] HID: a4tech: use A4_2WHEEL_MOUSE_HACK_B8 for A4TECH NB-95

[Greg Kroah-Hartman]

From: Mateusz Jończyk <mat.jonczyk@o2.pl>

[ Upstream commit 9858c74c29e12be5886280725e781cb735b2aca6 ]

This mouse has a horizontal wheel that requires special handling.
Without this patch, the horizontal wheel acts like a vertical wheel.

In the output of `hidrd-convert` for this mouse, there is a
`Usage (B8h)` field. It corresponds to a byte in packets sent by the
device that specifies which wheel generated an input event.

The name "A4TECH" is spelled in all capitals on the company website.

[PATCH 5.10 04/38] HID: hid-input: add mapping for emoji picker key

[Greg Kroah-Hartman]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

[ Upstream commit 7b229b13d78d112e2c5d4a60a3c6f602289959fa ]

HUTRR101 added a new usage code for a key that is supposed to invoke and
dismiss an emoji picker widget to assist users to locate and enter emojis.

This patch adds a new key definition KEY_EMOJI_PICKER and maps 0x0c/0x0d9
usage code to this new keycode. Additionally hid-debug is adjusted to
recognize this new usage code as well.

[PATCH 5.10 09/38] HID: usbhid: fix info leak in hid_submit_ctrl

[Greg Kroah-Hartman]

From: Anirudh Rayabharam <mail@anirudhrb.com>

[ Upstream commit 6be388f4a35d2ce5ef7dbf635a8964a5da7f799f ]

In hid_submit_ctrl(), the way of calculating the report length doesn't
take into account that report->size can be zero. When running the
syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to
calculate transfer_buffer_length as 16384. When this urb is passed to
the usb core layer, KMSAN reports an info leak of 16384 bytes.

To fix this, first modify hid_report_len() to account for the zero
report size case by using DIV_ROUND_UP for the division. Then, call it
from hid_submit_ctrl().

[PATCH 5.10 10/38] drm/tegra: sor: Do not leak runtime PM reference

[Greg Kroah-Hartman]

From: Pavel Machek (CIP) <pavel@denx.de>

[ Upstream commit 73a395c46704304b96bc5e2ee19be31124025c0c ]

It's theoretically possible for the runtime PM reference to leak if the
code fails anywhere between the pm_runtime_resume_and_get() and
pm_runtime_put() calls, so make sure to release the runtime PM reference
in that case.

Practically this will never happen because none of the functions will
fail on Tegra, but it's better for the code to be pedantic in case these
assumptions will ever become wrong.

[PATCH 5.10 11/38] gpu: host1x: Split up client initalization and registration

[Greg Kroah-Hartman]

From: Thierry Reding <treding@nvidia.com>

[ Upstream commit 0cfe5a6e758fb20be8ad3e8f10cb087cc8033eeb ]

In some cases we may need to initialize the host1x client first before
registering it. This commit adds a new helper that will do nothing but
the initialization of the data structure.

At the same time, the initialization is removed from the registration
function. Note, however, that for simplicity we explicitly initialize
the client when the host1x_client_register() function is called, as
opposed to the low-level __host1x_client_register() function. This
allows existing callers to remain unchanged.

[PATCH 5.10 12/38] drm/tegra: sor: Fully initialize SOR before registration

From: Thierry Reding <treding@nvidia.com>

[ Upstream commit 5dea42759bcef74b0802ea64b904409bc37f9045 ]

Before registering the SOR host1x client, make sure that it is fully
initialized. This avoids a potential race condition between the SOR's
probe and the host1x device initialization in cases where the SOR is
the final sub-device to register to a host1x instance.

[ Upstream commit 3c4e0147c269738a19c7d70cd32395600bcc0714 ]

The current control flow of IRQ number assignment to `irq` variable
allows a request of IRQ of unspecified value,
generating a warning under Clang compilation with omap1_defconfig on
linux-next:

arch/arm/mach-omap1/pm.c:656:11: warning: variable 'irq' is used

1 warning generated.

The patch provides a default value to the `irq` variable
along with a validity check.

[PATCH 5.10 15/38] gfs2: Prevent direct-I/O write fallback errors from getting lost

From: Andreas Gruenbacher <agruenba@redhat.com>

[ Upstream commit 43a511c44e58e357a687d61a20cf5ef1dc9e5a7c ]

When a direct I/O write falls entirely and falls back to buffered I/O and the
buffered I/O fails, the write failed with return value 0 instead of the error
number reported by the buffered I/O. Fix that.

[PATCH 5.10 16/38] gfs2: fix a deadlock on withdraw-during-mount

[Greg Kroah-Hartman]

From: Bob Peterson <rpeterso@redhat.com>

[ Upstream commit 865cc3e9cc0b1d4b81c10d53174bced76decf888 ]

Before this patch, gfs2 would deadlock because of the following
sequence during mount:

mount
   gfs2_fill_super
      gfs2_make_fs_rw <--- Detects IO error with glock
         kthread_stop(sdp->sd_quotad_process);
            <--- Blocked waiting for quotad to finish

logd
   Detects IO error and the need to withdraw
   calls gfs2_withdraw
      gfs2_make_fs_ro
         kthread_stop(sdp->sd_quotad_process);
            <--- Blocked waiting for quotad to finish

gfs2_quotad
   gfs2_statfs_sync
      gfs2_glock_wait <---- Blocked waiting for statfs glock to be granted

glock_work_func
   do_xmote <---Detects IO error, can't release glock: blocked on withdraw
      glops->go_inval
      glock_blocked_by_withdraw
         requeue glock work & exit <--- work requeued, blocked by withdraw

This patch makes a special exception for the statfs system inode glock,
which allows the statfs glock UNLOCK to proceed normally. That allows the
quotad daemon to exit during the withdraw, which allows the logd daemon
to exit during the withdraw, which allows the mount to exit.

[PATCH 5.10 18/38] riscv: Use -mno-relax when using lld linker

[Greg Kroah-Hartman]

From: Khem Raj <raj.khem@gmail.com>

[ Upstream commit ec3a5cb61146c91f0f7dcec8b7e7157a4879a9ee ]

lld does not implement the RISCV relaxation optimizations like GNU ld
therefore disable it when building with lld, Also pass it to
assembler when using external GNU assembler ( LLVM_IAS != 1 ), this
ensures that relevant assembler option is also enabled along. if these
options are not used then we see following relocations in objects

0000000000000000 R_RISCV_ALIGN     *ABS*+0x0000000000000002

These are then rejected by lld
ld.lld: error: capability.c:(.fixup+0x0): relocation R_RISCV_ALIGN requires unimplemented linker relaxation; recompile with -mno-relax but the .o is already compiled with -mno-relax

[PATCH 5.10 19/38] gfs2: Fix use-after-free in gfs2_glock_shrink_scan

[Greg Kroah-Hartman]

From: Hillf Danton <hdanton@sina.com>

[ Upstream commit 1ab19c5de4c537ec0d9b21020395a5b5a6c059b2 ]

The GLF_LRU flag is checked under lru_lock in gfs2_glock_remove_from_lru() to
remove the glock from the lru list in __gfs2_glock_put().

On the shrink scan path, the same flag is cleared under lru_lock but because
of cond_resched_lock(&lru_lock) in gfs2_dispose_glock_lru(), progress on the
put side can be made without deleting the glock from the lru list.

Keep GLF_LRU across the race window opened by cond_resched_lock(&lru_lock) to
ensure correct behavior on both sides - clear GLF_LRU after list_del under
lru_lock.

[PATCH 5.10 23/38] Bluetooth: Add a new USB ID for RTL8822CE

[Greg Kroah-Hartman]

From: Larry Finger <Larry.Finger@lwfinger.net>

[ Upstream commit 4d96d3b0efee6416ef0d61b76aaac6f4a2e15b12 ]

Some models of the RTL8822ce utilize a different USB ID. Add this
new one to the Bluetooth driver.

[PATCH 5.10 25/38] nvme-loop: reset queue count to 1 in nvme_loop_destroy_io_queues()

[Greg Kroah-Hartman]

From: Hannes Reinecke <hare@suse.de>

[ Upstream commit a6c144f3d2e230f2b3ac5ed8c51e0f0391556197 ]

The queue count is increased in nvme_loop_init_io_queues(), so we
need to reset it to 1 at the end of nvme_loop_destroy_io_queues().
Otherwise the function is not re-entrant safe, and crash will happen
during concurrent reset and remove calls.

[PATCH 5.10 28/38] nvme-loop: do not warn for deleted controllers during reset

From: Hannes Reinecke <hare@suse.de>

[ Upstream commit 6622f9acd29cd4f6272720e827e6406f5a970cb0 ]

During concurrent reset and delete calls the reset workqueue is
flushed, causing nvme_loop_reset_ctrl_work() to be executed when
the controller is in state DELETING or DELETING_NOIO.
But this is expected, so we shouldn't issue a WARN_ON here.

[PATCH 5.10 29/38] net: ipconfig: Dont override command-line hostnames or domains

[Greg Kroah-Hartman]

From: Josh Triplett <josh@joshtriplett.org>

[ Upstream commit b508d5fb69c2211a1b860fc058aafbefc3b3c3cd ]

If the user specifies a hostname or domain name as part of the ip=
command-line option, preserve it and don't overwrite it with one
supplied by DHCP/BOOTP.

For instance, ip=::::myhostname::dhcp will use "myhostname" rather than
ignoring and overwriting it.

Fix the comment on ic_bootp_string that suggests it only copies a string
"if not already set"; it doesn't have any such logic.

[PATCH 5.10 30/38] drm/amd/display: Allow bandwidth validation for 0 streams.

From: Bindu Ramamurthy <bindu.r@amd.com>

[ Upstream commit ba8e59773ae59818695d1e20b8939282da80ec8c ]

[Why]
Bandwidth calculations are triggered for non zero streams, and
in case of 0 streams, these calculations were skipped with
pstate status not being updated.

[How]
As the pstate status is applicable for non zero streams, check
added for allowing 0 streams inline with dcn internal bandwidth
validations.

[PATCH 5.10 32/38] drm/amd/display: Fix overlay validation by considering cursors

[Greg Kroah-Hartman]

From: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com>

[ Upstream commit 33f409e60eb0c59a4d0d06a62ab4642a988e17f7 ]

A few weeks ago, we saw a two cursor issue in a ChromeOS system. We
fixed it in the commit:

 drm/amd/display: Fix two cursor duplication when using overlay
 (read the commit message for more details)

After this change, we noticed that some IGT subtests related to
kms_plane and kms_plane_scaling started to fail. After investigating
this issue, we noticed that all subtests that fail have a primary plane
covering the overlay plane, which is currently rejected by amdgpu dm.
Fail those IGT tests highlight that our verification was too broad and
compromises the overlay usage in our drive. This patch fixes this issue
by ensuring that we only reject commits where the primary plane is not
fully covered by the overlay when the cursor hardware is enabled. With
this fix, all IGT tests start to pass again, which means our overlay
support works as expected.

Re: [PATCH 5.10 32/38] drm/amd/display: Fix overlay validation by considering cursors

[Harry Wentland]

Hi Greg

Please drop this from 5.4, 5.10, or 5.12 stable kernels as it's apt to break any userspace that is using the legacy cursor IOCTL, which is most userspace.

We are in the process of reverting this on amd-staging-drm-next. Siqueira will send a patch.

Thanks,
Harry

[PATCH 5.10 33/38] drm/amd/display: Fix potential memory leak in DMUB hw_init

[Greg Kroah-Hartman]

From: Roman Li <roman.li@amd.com>

[ Upstream commit c5699e2d863f58221044efdc3fa712dd32d55cde ]

[Why]
On resume we perform DMUB hw_init which allocates memory:
dm_resume->dm_dmub_hw_init->dc_dmub_srv_create->kzalloc
That results in memory leak in suspend/resume scenarios.

[How]
Allocate memory for the DC wrapper to DMUB only if it was not
allocated before.
No need to reallocate it on suspend/resume.

[Why]
When some tools performing psp mailbox attack, the readback value
of register can be a random value which may break psp.

This patch breaks systemd-resolved. It is 100% reproducible on two of
my systems, but there are also systems where I cannot reproduce it. The
problem manifests itself as SERVFAIL on every DNS query.

Just reverting this patch from 5.10.45 fixes the problem for me.

Is Linus's tree also broken for you?  It should be reverted there first.

Looks like this patch was reverted in Linus's tree:
d2e381c4963663bca6f30c3b996fa4dbafe8fcb5 (rtnetlink: Fix regression in
bridge VLAN configuration)


Also after some investigation I think my problem was actually with
NetworkManager as systemd-networkd + systemd-resolved works fine.

$ grep ^dns /etc/NetworkManager/NetworkManager.conf 
dns=systemd-resolved
