[PATCH AUTOSEL 4.19 03/11] irqchip/sifive-plic: Add missing thead, c900-plic match string

[Sasha Levin]

From: Guo Ren <guoren@linux.alibaba.com>

[ Upstream commit 1d4df649cbb4b26d19bea38ecff4b65b10a1bbca ]

The thead,c900-plic has been used in opensbi to distinguish
PLIC [1]. Although PLICs have the same behaviors in Linux,
they are different hardware with some custom initializing in
firmware(opensbi).

Qute opensbi patch commit-msg by Samuel:

  The T-HEAD PLIC implementation requires setting a delegation bit
  to allow access from S-mode. Now that the T-HEAD PLIC has its own
  compatible string, set this bit automatically from the PLIC driver,
  instead of reaching into the PLIC's MMIO space from another driver.

The "thead,c900-plic" string is added into single place in the
kernel. This means that a) it will probably not do anything useful in
-stable kernels and b) it is certainly missing documentation etc.

In mainline, string is documented in
Documentation/devicetree/bindings/interrupt-controller/sifive,plic-1.0.0.yaml

(b) is certainly true. And to make the above comment useful, the missing
patch is 321a8be37e1a ("dt-bindings: update riscv plic compatible
string").

Regarding (a), the DT is provided by the firmware (as it should
be on any reasonable platform). As such, no need for this string to be
mentioned anywhere else but in the documentation.

Now, the real question is where there is any point in backporting
this to such an old kernel, as this HW is unlikely to ever run it.

[PATCH AUTOSEL 4.19 04/11] netfilter: conntrack: don't refresh sctp entries in closed state

[Sasha Levin]

From: Florian Westphal <fw@strlen.de>

[ Upstream commit 77b337196a9d87f3d6bb9b07c0436ecafbffda1e ]

Vivek Thrivikraman reported:
 An SCTP server application which is accessed continuously by client
 application.
 When the session disconnects the client retries to establish a connection.
 After restart of SCTP server application the session is not established
 because of stale conntrack entry with connection state CLOSED as below.

 (removing this entry manually established new connection):

 sctp 9 CLOSED src=10.141.189.233 [..]  [ASSURED]

Just skip timeout update of closed entries, we don't want them to
stay around forever.

[PATCH AUTOSEL 4.19 06/11] kconfig: let 'shell' return enough output for deep path names

[Sasha Levin]

From: Brenda Streiff <brenda.streiff@ni.com>

[ Upstream commit 8a4c5b2a6d8ea079fa36034e8167de87ab6f8880 ]

The 'shell' built-in only returns the first 256 bytes of the command's
output. In some cases, 'shell' is used to return a path; by bumping up
the buffer size to 4096 this lets us capture up to PATH_MAX.

The specific case where I ran into this was due to commit 1e860048c53e
("gcc-plugins: simplify GCC plugin-dev capability test"). After this
change, we now use `$(shell,$(CC) -print-file-name=plugin)` to return
a path; if the gcc path is particularly long, then the path ends up
truncated at the 256 byte mark, which makes the HAVE_GCC_PLUGINS
depends test always fail.

If the idea is to support up-to PATH_MAX, perhaps open-coded 4096
should be replaced by PATH_MAX in the code, too?

[PATCH AUTOSEL 4.19 07/11] ata: libata-core: Disable TRIM on M88V29

[Sasha Levin]

From: Zoltán Böszörményi <zboszor@gmail.com>

[ Upstream commit c8ea23d5fa59f28302d4e3370c75d9c308e64410 ]

This device is a CF card, or possibly an SSD in CF form factor.
It supports NCQ and high speed DMA.

While it also advertises TRIM support, I/O errors are reported
when the discard mount option fstrim is used. TRIM also fails
when disabling NCQ and not just as an NCQ command.

TRIM must be disabled for this device.

[PATCH AUTOSEL 4.19 08/11] tracing: Fix tp_printk option related with tp_printk_stop_on_boot

[Sasha Levin]

From: JaeSang Yoo <js.yoo.5b@gmail.com>

[ Upstream commit 3203ce39ac0b2a57a84382ec184c7d4a0bede175 ]

The kernel parameter "tp_printk_stop_on_boot" starts with "tp_printk" which is
the same as another kernel parameter "tp_printk". If "tp_printk" setup is
called before the "tp_printk_stop_on_boot", it will override the latter
and keep it from being set.

This is similar to other kernel parameter issues, such as:
  Commit 745a600cf1a6 ("um: console: Ignore console= option")
or init/do_mounts.c:45 (setup function of "ro" kernel param)

Fix it by checking for a "_" right after the "tp_printk" and if that
exists do not process the parameter.

AFAICT this is already in 4.19.X-stable queue, so it can be dropped
from AUTOSEL.

[PATCH AUTOSEL 4.19 11/11] net: macb: Align the dma and coherent dma masks

[Sasha Levin]

From: Marc St-Amand <mstamand@ciena.com>

[ Upstream commit 37f7860602b5b2d99fc7465f6407f403f5941988 ]

Single page and coherent memory blocks can use different DMA masks
when the macb accesses physical memory directly. The kernel is clever
enough to allocate pages that fit into the requested address width.

When using the ARM SMMU, the DMA mask must be the same for single
pages and big coherent memory blocks. Otherwise the translation
tables turn into one big mess.

Since using the same DMA mask does not hurt direct 1:1 physical
memory mappings, this commit always aligns DMA and coherent masks.
