[PATCH AUTOSEL 4.14 01/31] scsi: lpfc: Fix incorrect dbde assignment when building target abts wqe

[Sasha Levin]

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit 9302154c07bff4e7f7f43c506a1ac84540303d06 ]

The wqe_dbde field indicates whether a Data BDE is present in Words 0:2 and
should therefore should be clear in the abts request wqe. By setting the
bit we can be misleading fw into error cases.

Clear the wqe_dbde field.

[PATCH AUTOSEL 4.14 02/31] scsi: lpfc: Fix pt2pt connection does not recover after LOGO

[Sasha Levin]

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit bd4f5100424d17d4e560d6653902ef8e49b2fc1f ]

On a pt2pt setup, between 2 initiators, if one side issues a a LOGO, there
is no relogin attempt. The FC specs are grey in this area on which port
(higher wwn or not) is to re-login.

As there is no spec guidance, unconditionally re-PLOGI after the logout to
ensure a login is re-established.

[PATCH AUTOSEL 4.14 05/31] power: supply: bq27xxx: fix power_avg for newer ICs

[Sasha Levin]

From: Matthias Schiffer <matthias.schiffer@ew.tq-group.com>

[ Upstream commit c4d57c22ac65bd503716062a06fad55a01569cac ]

On all newer bq27xxx ICs, the AveragePower register contains a signed
value; in addition to handling the raw value as unsigned, the driver
code also didn't convert it to µW as expected.

At least for the BQ28Z610, the reference manual incorrectly states that
the value is in units of 1mW and not 10mW. I have no way of knowing
whether the manuals of other supported ICs contain the same error, or if
there are models that actually use 1mW. At least, the new code shouldn't
be *less* correct than the old version for any device.

power_avg is removed from the cache structure, se we don't have to
extend it to store both a signed value and an error code. Always getting
an up-to-date value may be desirable anyways, as it avoids inconsistent
current and power readings when switching between charging and
discharging.

[PATCH AUTOSEL 4.14 06/31] extcon: arizona: Fix some issues when HPDET IRQ fires after the jack has been unplugged

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit c309a3e8793f7e01c4a4ec7960658380572cb576 ]

When the jack is partially inserted and then removed again it may be
removed while the hpdet code is running. In this case the following
may happen:

1. The "JACKDET rise" or ""JACKDET fall" IRQ triggers
2. arizona_jackdet runs and takes info->lock
3. The "HPDET" IRQ triggers
4. arizona_hpdet_irq runs, blocks on info->lock
5. arizona_jackdet calls arizona_stop_mic() and clears info->hpdet_done
6. arizona_jackdet releases info->lock
7. arizona_hpdet_irq now can continue running and:
7.1 Calls arizona_start_mic() (if a mic was detected)
7.2 sets info->hpdet_done

Step 7 is undesirable / a bug:
7.1 causes the device to stay in a high power-state (with MICVDD enabled)
7.2 causes hpdet to not run on the next jack insertion, which in turn
    causes the EXTCON_JACK_HEADPHONE state to never get set

This fixes both issues by skipping these 2 steps when arizona_hpdet_irq
runs after the jack has been unplugged.

Add a fix for the memory leak bugs that can occur when the

it when errors occur.
Add a better error handling that deallocate the unused buffers before the

[PATCH AUTOSEL 4.14 11/31] drm/bridge/analogix/anx78xx: Setup encoder before registering connector

[Sasha Levin]

From: Lyude Paul <lyude@redhat.com>

[ Upstream commit 9962849d0871f5e53d0e3b3d84561f8f2847fbf4 ]

Since encoder mappings for connectors are exposed to userspace, we should
be attaching the encoder before exposing the connector to userspace. Just a
drive-by fix for an issue I noticed while fixing up usages of
drm_dp_aux_init()/drm_dp_aux_register() across the tree.

[PATCH AUTOSEL 4.14 12/31] drm/bridge/analogix/anx78xx: Cleanup on error in anx78xx_bridge_attach()

[Sasha Levin]

From: Lyude Paul <lyude@redhat.com>

[ Upstream commit 212ee8db84600f7b279b8645c62a112bff310995 ]

Just another issue I noticed while correcting usages of
drm_dp_aux_init()/drm_dp_aux_register() around the tree. If any of the
steps in anx78xx_bridge_attach() fail, we end up leaking resources. So,
let's fix that (and fix leaking a DP AUX adapter in the process) by
unrolling on errors.

[PATCH AUTOSEL 4.14 15/31] scsi: qla2xxx: Fix use after free in bsg

[Sasha Levin]

From: Quinn Tran <qutran@marvell.com>

[ Upstream commit 2ce35c0821afc2acd5ee1c3f60d149f8b2520ce8 ]

On bsg command completion, bsg_job_done() was called while qla driver
continued to access the bsg_job buffer. bsg_job_done() would free up
resources that ended up being reused by other task while the driver
continued to access the buffers. As a result, driver was reading garbage
data.

[PATCH AUTOSEL 4.14 17/31] media: em28xx: fix memory leak

[Sasha Levin]

From: Muhammad Usama Anjum <musamaanjum@gmail.com>

[ Upstream commit 0ae10a7dc8992ee682ff0b1752ff7c83d472eef1 ]

If some error occurs, URB buffers should also be freed. If they aren't
freed with the dvb here, the em28xx_dvb_fini call doesn't frees the URB
buffers as dvb is set to NULL. The function in which error occurs should
do all the cleanup for the allocations it had done.

Tested the patch with the reproducer provided by syzbot. This patch
fixes the memleak.

[PATCH AUTOSEL 4.14 19/31] clk: socfpga: arria10: Fix memory leak of socfpga_clk on error return

[Sasha Levin]

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 657d4d1934f75a2d978c3cf2086495eaa542e7a9 ]

There is an error return path that is not kfree'ing socfpga_clk leading
to a memory leak. Fix this by adding in the missing kfree call.

[PATCH AUTOSEL 4.14 20/31] power: supply: generic-adc-battery: fix possible use-after-free in gab_remove()

[Sasha Levin]

From: Yang Yingliang <yangyingliang@huawei.com>

[ Upstream commit b6cfa007b3b229771d9588970adb4ab3e0487f49 ]

This driver's remove path calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This means
that the callback function may still be running after the driver's
remove function has finished, which would result in a use-after-free.

Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.

[PATCH AUTOSEL 4.14 25/31] media: dvb-usb: fix memory leak in dvb_usb_adapter_init

[Sasha Levin]

From: Pavel Skripkin <paskripkin@gmail.com>

[ Upstream commit b7cd0da982e3043f2eec7235ac5530cb18d6af1d ]

syzbot reported memory leak in dvb-usb. The problem was
in invalid error handling in dvb_usb_adapter_init().

for (n = 0; n < d->props.num_adapters; n++) {
....
	if ((ret = dvb_usb_adapter_stream_init(adap)) ||
		(ret = dvb_usb_adapter_dvb_init(adap, adapter_nrs)) ||
		(ret = dvb_usb_adapter_frontend_init(adap))) {
		return ret;
	}
...
	d->num_adapters_initialized++;
...
}

In case of error in dvb_usb_adapter_dvb_init() or
dvb_usb_adapter_dvb_init() d->num_adapters_initialized won't be
incremented, but dvb_usb_adapter_exit() relies on it:

	for (n = 0; n < d->num_adapters_initialized; n++)

So, allocated objects won't be freed.

[PATCH AUTOSEL 4.14 26/31] media: gscpa/stv06xx: fix memory leak

[Sasha Levin]

From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

[ Upstream commit 4f4e6644cd876c844cdb3bea2dd7051787d5ae25 ]

For two of the supported sensors the stv06xx driver allocates memory which
is stored in sd->sensor_priv. This memory is freed on a disconnect, but if
the probe() fails, then it isn't freed and so this leaks memory.

Add a new probe_error() op that drivers can use to free any allocated
memory in case there was a probe failure.

Thanks to Pavel Skripkin <paskripkin@gmail.com> for discovering the cause
of the memory leak.

[PATCH AUTOSEL 4.14 27/31] drm/msm/mdp5: Configure PP_SYNC_HEIGHT to double the vtotal

[Sasha Levin]

From: Marijn Suijten <marijn.suijten@somainline.org>

[ Upstream commit 2ad52bdb220de5ab348098e3482b01235d15a842 ]

Leaving this at a close-to-maximum register value 0xFFF0 means it takes
very long for the MDSS to generate a software vsync interrupt when the
hardware TE interrupt doesn't arrive.  Configuring this to double the
vtotal (like some downstream kernels) leads to a frame to take at most
twice before the vsync signal, until hardware TE comes up.

In this case the hardware interrupt responsible for providing this
signal - "disp-te" gpio - is not hooked up to the mdp5 vsync/pp logic at
all.  This solves severe panel update issues observed on at least the
Xperia Loire and Tone series, until said gpio is properly hooked up to
an irq.

[PATCH AUTOSEL 4.14 29/31] scsi: lpfc: Fix crash when a REG_RPI mailbox fails triggering a LOGO response

[Sasha Levin]

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit fffd18ec6579c2d9c72b212169259062fe747888 ]

Fix a crash caused by a double put on the node when the driver completed an
ACC for an unsolicted abort on the same node.  The second put was executed
by lpfc_nlp_not_used() and is wrong because the completion routine executes
the nlp_put when the iocbq was released.  Additionally, the driver is
issuing a LOGO then immediately calls lpfc_nlp_set_state to put the node
into NPR.  This call does nothing.

Remove the lpfc_nlp_not_used call and additional set_state in the
completion routine.  Remove the lpfc_nlp_set_state post issue_logo.  Isn't
necessary.

[PATCH AUTOSEL 4.14 30/31] scsi: lpfc: Remove unsupported mbox PORT_CAPABILITIES logic

[Sasha Levin]

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit b62232ba8caccaf1954e197058104a6478fac1af ]

SLI-4 does not contain a PORT_CAPABILITIES mailbox command (only SLI-3
does, and SLI-3 doesn't use it), yet there are SLI-4 code paths that have
code to issue the command.  The command will always fail.

Remove the code for the mailbox command and leave only the resulting
"failure path" logic.

[PATCH AUTOSEL 4.14 31/31] scsi: libfc: Fix a format specifier

[Sasha Levin]

From: Bart Van Assche <bvanassche@acm.org>

[ Upstream commit 90d6697810f06aceea9de71ad836a8c7669789cd ]

Since the 'mfs' member has been declared as 'u32' in include/scsi/libfc.h,
use the %u format specifier instead of %hu. This patch fixes the following
clang compiler warning:

warning: format specifies type
      'unsigned short' but the argument has type 'u32' (aka 'unsigned int')
      [-Wformat]
                             "lport->mfs:%hu\n", mfs, lport->mfs);
                                         ~~~          ^~~~~~~~~~
                                         %u
