[PATCH AUTOSEL 4.9 01/10] NFSv4.1 handle ERR_DELAY error reclaiming locking state on delegation recall

[Sasha Levin]

From: Olga Kornievskaia <kolga@netapp.com>

[ Upstream commit 3d7a9520f0c3e6a68b6de8c5812fc8b6d7a52626 ]

A client should be able to handle getting an ERR_DELAY error
while doing a LOCK call to reclaim state due to delegation being
recalled. This is a transient error that can happen due to server
moving its volumes and invalidating its file location cache and
upon reference to it during the LOCK call needing to do an
expensive lookup (leading to an ERR_DELAY error on a PUTFH).

[PATCH AUTOSEL 4.9 03/10] scsi: lpfc: Fix FLOGI/PLOGI receive race condition in pt2pt discovery

[Sasha Levin]

From: James Smart <james.smart@broadcom.com>

[ Upstream commit 7b08e89f98cee9907895fabb64cf437bc505ce9a ]

The driver is unable to successfully login with remote device. During pt2pt
login, the driver completes its FLOGI request with the remote device having
WWN precedence.  The remote device issues its own (delayed) FLOGI after
accepting the driver's and, upon transmitting the FLOGI, immediately
recognizes it has already processed the driver's FLOGI thus it transitions
to sending a PLOGI before waiting for an ACC to its FLOGI.

In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI
being received and an ACC sent. The issue is that the PLOGI reception
occurs before the response from the adapter from the FLOGI ACC is
received. Processing of the PLOGI sets state flags to perform the REG_RPI
mailbox command and proceed with the rest of discovery on the port. The
same completion routine used by both FLOGI and PLOGI is generic in
nature. One of the things it does is clear flags, and those flags happen to
drive the rest of discovery.  So what happened was the PLOGI processing set
the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC
completes it doesn't see the flags and stops.

Fix by modifying the generic completion routine to not clear the rest of
discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated
with performing a mailbox command as part of its handling.  For things such
as FLOGI ACC, there isn't a subsequent action to perform with the adapter,
thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI
upon completion, thus there is a mailbox cmd ptr.

[PATCH AUTOSEL 4.9 04/10] regulator: pwm: Fix machine constraints application

[Sasha Levin]

From: Vincent Whitchurch <vincent.whitchurch@axis.com>

[ Upstream commit 59ae97a7a9e1499c2070e29841d1c4be4ae2994a ]

If the zero duty cycle doesn't correspond to any voltage in the voltage
table, the PWM regulator returns an -EINVAL from get_voltage_sel() which
results in the core erroring out with a "failed to get the current
voltage" and ending up not applying the machine constraints.

Instead, return -ENOTRECOVERABLE which makes the core set the voltage
since it's at an unknown value.

For example, with this device tree:

	fooregulator {
		compatible = "pwm-regulator";
		pwms = <&foopwm 0 100000>;
		regulator-min-microvolt = <2250000>;
		regulator-max-microvolt = <2250000>;
		regulator-name = "fooregulator";
		regulator-always-on;
		regulator-boot-on;
		voltage-table = <2250000 30>;
	};

Before this patch:

  fooregulator: failed to get the current voltage(-22)

After this patch:

  fooregulator: Setting 2250000-2250000uV
  fooregulator: 2250 mV

[PATCH AUTOSEL 4.9 05/10] spi: spi-loopback-test: Fix out-of-bounds read

[Sasha Levin]

From: Vincent Whitchurch <vincent.whitchurch@axis.com>

[ Upstream commit 837ba18dfcd4db21ad58107c65bfe89753aa56d7 ]

The "tx/rx-transfer - crossing PAGE_SIZE" test always fails when
len=131071 and rx_offset >= 5:

 spi-loopback-test spi0.0: Running test tx/rx-transfer - crossing PAGE_SIZE
 ...
   with iteration values: len = 131071, tx_off = 0, rx_off = 3
   with iteration values: len = 131071, tx_off = 0, rx_off = 4
   with iteration values: len = 131071, tx_off = 0, rx_off = 5
 loopback strangeness - rx changed outside of allowed range at: ...a4321000
   spi_msg@ffffffd5a4157690
     frame_length:  131071
     actual_length: 131071
     spi_transfer@ffffffd5a41576f8
       len:    131071
       tx_buf: ffffffd5a4340ffc

Note that rx_offset > 3 can only occur if the SPI controller driver sets
->dma_alignment to a higher value than 4, so most SPI controller drivers
are not affect.

The allocated Rx buffer is of size SPI_TEST_MAX_SIZE_PLUS, which is 132
KiB (assuming 4 KiB pages).  This test uses an initial offset into the
rx_buf of PAGE_SIZE - 4, and a len of 131071, so the range expected to
be written in this transfer ends at (4096 - 4) + 5 + 131071 == 132 KiB,
which is also the end of the allocated buffer.  But the code which
verifies the content of the buffer reads a byte beyond the allocated
buffer and spuriously fails because this out-of-bounds read doesn't
return the expected value.

Fix this by using ITERATE_LEN instead of ITERATE_MAX_LEN to avoid
testing sizes which cause out-of-bounds reads.

[ Upstream commit 0a355aeb24081e4538d4d424cd189f16c0bbd983 ]

If something goes wrong (such as the SCL being stuck low) then we need
to reset the PCA chip. The issue with this is that on reset we lose all
config settings and the chip ends up in a disabled state which results
in a lock up/high CPU usage. We need to re-apply any configuration that
had previously been set and re-enable the chip.

[PATCH AUTOSEL 4.9 10/10] gcov: add support for GCC 10.1

From: Peter Oberparleiter <oberpar@linux.ibm.com>

[ Upstream commit 40249c6962075c040fd071339acae524f18bfac9 ]

Using gcov to collect coverage data for kernels compiled with GCC 10.1
causes random malfunctions and kernel crashes.  This is the result of a
changed GCOV_COUNTERS value in GCC 10.1 that causes a mismatch between
the layout of the gcov_info structure created by GCC profiling code and
the related structure used by the kernel.

Fix this by updating the in-kernel GCOV_COUNTERS value.  Also re-enable
config GCOV_KERNEL for use with GCC 10.
