[PATCH AUTOSEL 4.14 1/9] 9p: virtio: make sure 'offs' is initialized in zc_request

[Sasha Levin]

From: Dominique Martinet <asmadeus@codewreck.org>

[ Upstream commit 4a73edab69d3a6623f03817fe950a2d9585f80e4 ]

Similarly to the previous patch: offs can be used in handle_rerrors
without initializing on small payloads; in this case handle_rerrors will
not use it because of the size check, but it doesn't hurt to make sure
it is zero to please scan-build.

This fixes the following warning:
net/9p/trans_virtio.c:539:3: warning: 3rd function call argument is an uninitialized value [core.CallAndMessage]
                handle_rerror(req, in_hdr_len, offs, in_pages);

[PATCH AUTOSEL 4.14 2/9] ASoC: da7219: Flush pending AAD IRQ when suspending

[Sasha Levin]

From: Dmytro Maluka <dmy@semihalf.com>

[ Upstream commit 91e292917dad64ab8d1d5ca2ab3069ad9dac6f72 ]

da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just
before suspending DA7219 and not handled yet, so the IRQ handler may
still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.

This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

[  355.876211] i2c_designware i2c_designware.3: Transfer while suspended
[  355.876245] WARNING: CPU: 2 PID: 3576 at drivers/i2c/busses/i2c-designware-master.c:570 i2c_dw_xfer+0x411/0x440

which indicates that the AAD IRQ handler is unexpectedly running when
DA7219 is suspended, and as a result, is trying to read data from DA7219
over I2C and is hitting the I2C driver "Transfer while suspended"
failure.

However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending
IRQ but rather looks like a DA7219 hardware issue with an IRQ
unexpectedly generated after jack detection is already disabled.

[PATCH AUTOSEL 4.14 4/9] vxlan: generalize vxlan_parse_gpe_hdr and remove unused args

[Sasha Levin]

From: Jiri Benc <jbenc@redhat.com>

[ Upstream commit 17a0a64448b568442a101de09575f81ffdc45d15 ]

The vxlan_parse_gpe_hdr function extracts the next protocol value from
the GPE header and marks GPE bits as parsed.

In order to be used in the next patch, split the function into protocol
extraction and bit marking. The bit marking is meaningful only in
vxlan_rcv; move it directly there.

Rename the function to vxlan_parse_gpe_proto to reflect what it now
does. Remove unused arguments skb and vxflags. Move the function earlier
in the file to allow it to be called from more places in the next patch.

[PATCH AUTOSEL 4.14 5/9] m68k: Fix invalid .section syntax

[Sasha Levin]

From: Ben Hutchings <benh@debian.org>

[ Upstream commit 922a9bd138101e3e5718f0f4d40dba68ef89bb43 ]

gas supports several different forms for .section for ELF targets,
including:
    .section NAME [, "FLAGS"[, @TYPE[,FLAG_SPECIFIC_ARGUMENTS]]]
and:
    .section "NAME"[, #FLAGS...]

In several places we use a mix of these two forms:
    .section NAME, #FLAGS...

A current development snapshot of binutils (2.40.50.20230611) treats
this mixed syntax as an error.

Change to consistently use:
    .section NAME, "FLAGS"
as is used elsewhere in the kernel.

[PATCH AUTOSEL 4.14 6/9] s390/dasd: use correct number of retries for ERP requests

[Sasha Levin]

From: Stefan Haberland <sth@linux.ibm.com>

[ Upstream commit acea28a6b74f458defda7417d2217b051ba7d444 ]

If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.

The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.

Correctly use the number of retries of the original request for ERP
requests.

If the current task fails the check for the queried capability via
`capable(CAP_SYS_ADMIN)` LSMs like SELinux generate a denial message.
Issuing such denial messages unnecessarily can lead to a policy author
granting more privileges to a subject than needed to silence them.
