* [PATCH net] r8152: fix the setting of detecting the linking change for runtime suspend
From: Hayes Wang @ 2019-07-01 7:53 UTC (permalink / raw)
To: netdev; +Cc: nic_swsd, linux-kernel, linux-usb, Hayes Wang
1. Rename r8153b_queue_wake() to r8153_queue_wake().
2. Correct the setting. The enable bit should be 0xd38c bit 0. Besides,
the 0xd38a bit 0 and 0xd398 bit 8 have to be cleared for both enabled
and disabled.

When the vendor driver assigns a random MAC address, it writes it to the
chip. The related registers may be persistent (can't say exactly due to
missing documentation).

Hi all,
After merging the bpf-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/net/ethernet/mellanox/mlx5/core/en_main.c:1605:5: error: conflicting types for 'mlx5e_open_cq'

Hi all,
Today's linux-next merge of the bpf-next tree got a conflict in:
drivers/net/ethernet/mellanox/mlx5/core/en_main.c
between commit:
8960b38932be ("linux/dim: Rename externally used net_dim members")
from the net-next tree and commits:
db05815b36cb ("net/mlx5e: Add XSK zero-copy support")
0a06382fa406 ("net/mlx5e: Encapsulate open/close queues into a function")
from the bpf-next tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

* [PATCHv2] selftests/net: skip psock_tpacket test if KALLSYMS was not enabled
From: Po-Hsu Lin @ 2019-07-01 4:40 UTC (permalink / raw)
To: davem, shuah, linux-kselftest; +Cc: netdev, linux-kernel
The psock_tpacket test will need to access /proc/kallsyms, this would
require the kernel config CONFIG_KALLSYMS to be enabled first.
Apart from adding CONFIG_KALLSYMS to the net/config file here, check the
file existence to determine if we can run this test will be helpful to
avoid a false-positive test result when testing it directly with the
following commad against a kernel that have CONFIG_KALLSYMS disabled:

Previously, macsec_post_decrypt could be called on the original skb if
the initial condition was false and macsec_decrypt is skipped. That
was probably unintended. Either way, then this is a functional change,
and perhaps a bugfix?

There is a subtle difference. skb_unshare() acts on cloned skbs, not
shared skbs.
It creates a private copy of data if clones may access it
concurrently, which clearly is needed when modifying for decryption.
At rx_handler, I don't think a shared skb happen (unlike clones, e.g.,
from packet sockets). But it is peculiar that most, if not all,
rx_handlers seem to test for it. That have started with the bridge
device:
commit 7b995651e373d6424f81db23f2ec503306dfd7f0
Author: Herbert Xu <herbert@gondor.apana.org.au>
Date: Sun Oct 14 00:39:01 2007 -0700
[BRIDGE]: Unshare skb upon entry
Due to the special location of the bridging hook, it should never see a
shared packet anyway (certainly not with any in-kernel code). So it
makes sense to unshare the skb there if necessary as that will greatly
simplify the code below it (in particular, netfilter).
Anyway, remove the check only if certain.

1/7: add CONFIG_CC_CAN_LINK to use it in 2/7
2/7: Compile-test exported headers
3/7: Do not generate intermediate wrappers.
This will avoid header search path issue.
4/7: maybe useful for 7/7 and in some other places.
Add header-test-pattern-y syntax.
5/7: Minor cleanup of gen_kheaders.sh
6/7: Exclude all files without ".h" extension
from the kheaders_data.tar.xz
This will be needed by 7/7 because we need to
exclude "*.h.s" from the archive
7/7: Compile-test kernel-space headers in include/.
Masahiro Yamada (7):
init/Kconfig: add CONFIG_CC_CAN_LINK
kbuild: compile-test exported headers to ensure they are
self-contained
kbuild: do not create wrappers for header-test-y
kbuild: support header-test-pattern-y
kheaders: remove meaningless -R option of 'ls'
kheaders: include only headers into kheaders_data.tar.xz
kbuild: compile-test kernel headers to ensure they are self-contained

In-Reply-To: <20190701005845.12475-1-yamada.masahiro@socionext.com>
The headers in include/ are globally used in the kernel source tree
to provide common APIs. They are included from external modules, too.
It will be useful to make as many headers self-contained as possible
so that we do not have to rely on a specific include order.
There are more than 4000 headers in include/. In my rough analysis,
70% of them are already self-contained. With efforts, most of them
can be self-contained.
For now, we must exclude more than 1000 headers just because they
cannot be compiled as standalone units. I added them to header-test-.
The blacklist was mostly generated by a script, so the reason of the
breakage should be checked later.

Changes in v4:
- Fix vmlinux build error
- Exclude more headers for sparc
Changes in v3:
- Exclude more headers
(Tested for allnoconfig + CONFIG_HEADER_TEST=y)
Changes in v2:
- Add everything to test coverage, and exclude broken ones
- Rename 'Makefile' to 'Kbuild'
- Add CONFIG_KERNEL_HEADER_TEST option
