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.

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.

* [PATCH 2/7] kbuild: compile-test exported headers to ensure they are self-contained
From: Masahiro Yamada @ 2019-07-01 0:58 UTC (permalink / raw)

In-Reply-To: <20190701005845.12475-1-yamada.masahiro@socionext.com>
Multiple people have suggested compile-testing UAPI headers to ensure
they can be really included from user-space. "make headers_check" is
obviously not enough to catch bugs, and we often leak unresolved
references to user-space.
Use the new header-test-y syntax to implement it. Please note exported
headers are compile-tested with a completely different set of compiler
flags. The header search path is set to $(objtree)/usr/include since
exported headers should not include unexported ones.
We use -std=gnu89 for the kernel space since the kernel code highly
depends on GNU extensions. On the other hand, UAPI headers should be
written in more standardized C, so they are compiled with -std=c90.
This will emit errors if C++ style comments, the keyword 'inline', etc.
are used. Please use C style comments (/* ... */), '__inline__', etc.
in UAPI headers.
There is additional compiler requirement to enable this test because
many of UAPI headers include <stdlib.h>, <sys/ioctl.h>, <sys/time.h>,
etc. directly or indirectly. You cannot use kernel.org pre-built
toolchains [1] since they lack <stdlib.h>.
I reused CONFIG_CC_CAN_LINK to check the system header availability.
The intention is slightly different, but a compiler that can link
userspace programs provide system headers.
For now, a lot of headers need to be excluded because they cannot
be compiled standalone, but this is a good start point.

Changes in v4:
- Sort the blacklist alphabetically
- Add a little more comments
- Remove scripts/cc-system-headers.sh and reuse CC_CAN_LINK
Changes in v3: None
Changes in v2:
- Add CONFIG_CPU_{BIG,LITTLE}_ENDIAN guard to avoid build error
- Use 'header-test-' instead of 'no-header-test'
- Avoid weird 'find' warning when cleaning

Hmm, did some more testing:
did a rmmod r8168 and (after "un"blacklisting the r8169) modprobed the
r8169. This time r8169 came up nicely but with a complete different MAC
(forgot to not than one though).
So I guess the vendor compilation did other stuff besides just compiling
the r8168 kernel module.
Did another test:
blacklisted the r8168, renamed r8168.ko to r8168.bak, depmod -a and
powercycled the system. Funny it came up with both r8168 and r8169
loaded and I got my intended IP address from. DHCP, so r8168 somewhat
got loaded and used his MAC.
Did another rmmod r8168, rmmod r8169 and then modprobe r8169.
Even though I did NOT configure a MAC address myself manually it came up
with a new MAC address and of course got a dynamich IP address.
So I don't know where the vendor somewhat changed something (with his
compiling/installing) to the effect that r8169 now works?!?
Regards,
Karsten

This one shows that the vendor driver (r8168) uses a random MAC address.
Means the driver can't read a valid MAC address from the chip, maybe due
to a broken BIOS.
Alternatively you could use r8169 and set a MAC address manually with
ifconfig <if> hw ether <MAC address>

Didn't know that. Thanks for pointing that out.

Hmm, maybe I did make a mistake. Yes I just again got the same MAC
address again but the last poweron/offs were done with Hibernating where
I got the same IP-address with the same MAC.
Anyway I just did a complete Power-Off (shutdown) and I still got the
same MAC address and because of that the intended IP address.
I just naively did a recursive grep in /etc trying to find the MAC since
you implied that it has to be stored somewhere.
Also went through the AMI BIOS (Aptio Setup Utility) and couldn't find
anything related there. Only network-related setting seems to be:
"Network Stack Driver Support" which by default is disable. Other that
that it might of course be stored somewhere within the UEFI NVRAM.
Regards,
Karsten
