We use these Realtek chips on some of our boards that customers can
either purchase individually and integrate into their own designs or
they can get the module as part of a product.
In order to easily allow customers to reprogram the device (they may
want to do that if integrating the module into their own products), a
so-called ID EEPROM is part of the module that stores various bits of
information. The ethernet MAC address is part of that EEPROM.
Typically the ID EEPROM will contain a valid MAC address if the module
is part of a product, but if customers purchase the module individually,
it is expected that they use a MAC address from their own pool.
Typically early boot firmware will load the MAC address from the EEPROM
and store it in the ethernet device's device tree node so that the MAC
address programmed into the ID EEPROM will be used by the ethernet
device at runtime.

Good point. I can memset() mac_addr to make sure it is invalid, rather
than undefined, for chip versions that are not covered.

* [PATCH net-next] cxgb4: cxgb4_tc_u32: use struct_size() in kvzalloc()
From: Gustavo A. R. Silva @ 2019-01-29 17:05 UTC (permalink / raw)
To: Arjun Vynipadath, David S. Miller
Cc: netdev, linux-kernel, Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
instance = kvzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

I'd like to merge TLS1.3 support to net-next, which depends on this
commit. Can we get a net->net-next merge when convenient? Thanks

I am not confortable with adding support for S2RAM in mv88e6xxx yet because
as it was explained, we are aware of much complicated scenarios out there
to pretend that DSA /partly/ supports suspend-resume. The prefered approach
for the moment is to keep things simple and not supporting this feature yet,
especially at the mv88e6xxx driver level.
However crashing is unacceptable so I'm backing Andrew's point here, please
submit a fix to prevent the suspend (and crash) for the moment.
Sorry if you felt that your work is being delayed, it is much appreciated!
Thanks,
Vivien

ok, got you, so why do we need this line
parse_attr->num_mod_hdr_actions = 0;
in alloc_mod_hdr_actions()? this should be zero
by kzalloc somewhere, it got to confuse me..
I suggest to remove this zeroing, otherwise the patch LGTM, once you fix it

To quote the source:
/* +26 gets the maximum ethernet encapsulation, +7 & ~7 because the
* card needs room to do 8 byte alignment, +2 so we can reserve
* the first 2 bytes, and +16 gets room for the status word from the
* card.
*/
mdp->rx_buf_sz = (ndev->mtu <= 1492 ? PKT_BUF_SZ :
(((ndev->mtu + 26 + 7) & ~7) + 2 + 16));
I have no idea what they mean by status word and why it takes 16 bytes (and I even
have the R8A771x manual!) but I think these 16 bytes are where our checksum goes...
that's why I said there's plenty of space. :-)

Thank you! I'm not familiar with 'ip' at all, thought 'ifconfig' could do the same
thing easier but couldn't remember all the needed incantations... :-)

Hi,
after having a good night's sleep over that, it's obviously a merge
commit which cannot easily be reverted. How would I continue after
identifying a merge commit as the culprit?

git diff aea5f654e6b7..19725496da5602b401eae389736ab00d1817e264,

But, indeed, adding the call to __rtl8169_set_wol(tp, 0) fixes the issue
for me and the machine now wakes up from StR on a magic packet without
having to go through strange ethtool motions.
-------
Would that code change be suitable for the official kernel cod?

* [PATCH net] net: caif: call dev_consume_skb_any when skb xmit done
From: Yang Wei @ 2019-01-29 15:32 UTC (permalink / raw)
To: netdev; +Cc: dmitry.tarnyagin, davem, yang.wei9
From: Yang Wei <yang.wei9@zte.com.cn>
The skb shouled be consumed when xmit done, it makes drop profiles
(dropwatch, perf) more friendly.
dev_kfree_skb_irq()/kfree_skb() shouled be replaced by
dev_consume_skb_any(), it makes code cleaner.

* [PATCH bpf-next v3 2/3] libbpf: add support for using AF_XDP sockets
From: Magnus Karlsson @ 2019-01-29 15:12 UTC (permalink / raw)
To: magnus.karlsson, bjorn.topel, ast, daniel, netdev, jakub.kicinski,
bjorn.topel, qi.z.zhang
Cc: brouer
In-Reply-To: <1548774737-16579-1-git-send-email-magnus.karlsson@intel.com>
This commit adds AF_XDP support to libbpf. The main reason for this is
to facilitate writing applications that use AF_XDP by offering
higher-level APIs that hide many of the details of the AF_XDP
uapi. This is in the same vein as libbpf facilitates XDP adoption by
offering easy-to-use higher level interfaces of XDP
functionality. Hopefully this will facilitate adoption of AF_XDP, make
applications using it simpler and smaller, and finally also make it
possible for applications to benefit from optimizations in the AF_XDP
user space access code. Previously, people just copied and pasted the
code from the sample application into their application, which is not
desirable.
The interface is composed of two parts:
* Low-level access interface to the four rings and the packet
* High-level control plane interface for creating and setting
up umems and af_xdp sockets as well as a simple XDP program.

* [PATCH bpf-next v3 3/3] samples/bpf: convert xdpsock to use libbpf for AF_XDP access
From: Magnus Karlsson @ 2019-01-29 15:12 UTC (permalink / raw)
To: magnus.karlsson, bjorn.topel, ast, daniel, netdev, jakub.kicinski,
bjorn.topel, qi.z.zhang
Cc: brouer
In-Reply-To: <1548774737-16579-1-git-send-email-magnus.karlsson@intel.com>
This commit converts the xdpsock sample application to use the AF_XDP
functions present in libbpf. This cuts down the size of it by nearly
300 lines of code.
The default ring sizes plus the batch size has been increased and the
size of the umem area has decreased. This so that the sample application
will provide higher throughput. Note also that the shared umem code
has been removed from the sample as this is not supported by libbpf
at this point in time.

* [PATCH bpf-next v3 1/3] libbpf: move pr_*() functions to common header file

Move the pr_*() functions in libbpf.c to a common header file called
libbpf_internal.h. This so that the later libbpf AF_XDP helper library
code in xsk.c can use these printing functions too.

* [PATCH bpf-next v3 0/3] libbpf: adding AF_XDP support
From: Magnus Karlsson @ 2019-01-29 15:12 UTC (permalink / raw)
To: magnus.karlsson, bjorn.topel, ast, daniel, netdev, jakub.kicinski,
bjorn.topel, qi.z.zhang
Cc: brouer
This patch proposes to add AF_XDP support to libbpf. The main reason
for this is to facilitate writing applications that use AF_XDP by
offering higher-level APIs that hide many of the details of the AF_XDP
uapi. This is in the same vein as libbpf facilitates XDP adoption by
offering easy-to-use higher level interfaces of XDP
functionality. Hopefully this will facilitate adoption of AF_XDP, make
applications using it simpler and smaller, and finally also make it
possible for applications to benefit from optimizations in the AF_XDP
user space access code. Previously, people just copied and pasted the
code from the sample application into their application, which is not
desirable.
The proposed interface is composed of two parts:
* Low-level access interface to the four rings and the packet
* High-level control plane interface for creating and setting up umems
and AF_XDP sockets. This interface also loads a simple XDP program
that routes all traffic on a queue up to the AF_XDP socket.
The sample program has been updated to use this new interface and in
that process it lost roughly 300 lines of code. I cannot detect any
performance degradations due to the use of this library instead of the
previous functions that were inlined in the sample application. But I
did measure this on a slower machine and not the Broadwell that we
normally use.
The rings are now called xsk_ring and when a producer operates on it, it
is xsk_ring_prod and for a consumer it is xsk_ring_cons. This way we
can get some compile time error checking that the rings are used
correctly.
Comments and contenplations:
* The current behaviour is that the library loads an XDP program (if
requested to do so) but the clean up of this program is left to the
application. It would be possible to implement this cleanup in the
library, but it would require state to be kept on netdev level,
which there is none at the moment, and the synchronization of this
between processes. All this adding complexity. But when we get an
XDP program per queue id, then it becomes trivial to also remove the
XDP program when the application exits. This proposal from Jesper,
Björn and others will also improve the performance of libbpf, since
most of the XDP program code can be removed when that feature is
supported.
* In a future release, I am planning on adding a higher level data
plane interface too. This will be based around recvmsg and sendmsg
with the use of struct iovec for batching, without the user having
to know anything about the underlying four rings of an AF_XDP
socket. There will be one semantic difference though from the
standard recvmsg and that is that the kernel will fill in the iovecs
instead of the application. But the rest should be the same as the
libc versions so that application writers feel at home.
Patch 1: moves the pr_*() functions to a separate header file so that
the AF_XDP code can also use them.
Patch 2: adds AF_XDP support in libbpf
Patch 3: updates the xdpsock sample application to use the libbpf functions.
Changes v2 to v3:
* Added automatic loading of a simple XDP program that routes all
traffic on a queue up to the AF_XDP socket. This program loading
can be disabled.
* Updated function names to be consistent with the libbpf naming
convention
* Moved all code to xsk.[ch]
* Removed all the XDP program loading code from the sample since
this is now done by libbpf
* The initialization functions now return a handle as suggested by
Alexei
* const statements added in the API where applicable.
Changes v1 to v2:
* Fixed cleanup of library state on error.
* Moved API to initial version
* Prefixed all public functions by xsk__ instead of xsk_
* Added comment about changed default ring sizes, batch size and umem
size in the sample application commit message
* The library now only creates an Rx or Tx ring if the respective
parameter is != NULL
Note that for zero-copy to work on FVL you need the following patch:
"i40e: fix potential RX buffer starvation for AF_XDP". For ixgbe,
you need a similar patch called "ixgbe: fix potential RX buffer
starvation for AF_XDP" to make ZC work with libbpf. Both have been
submitted to net.
I based this patch set on bpf-next commit 3d2af27a84a8 ("Merge branch 'bpf-flow-dissector-tests'")

* [PATCH 01/28] net: thunderbolt: Unregister ThunderboltIP protocol handler when suspending

To: linux-kernel
Cc: Michael Jamet, Yehezkel Bernat, Andreas Noever, Lukas Wunner,

In-Reply-To: <20190129150143.12681-1-mika.westerberg@linux.intel.com>
The XDomain protocol messages may start as soon as Thunderbolt control
channel is started. This means that if the other host starts sending
ThunderboltIP packets early enough they will be passed to the network
driver which then gets confused because its resume hook is not called
yet.
Fix this by unregistering the ThunderboltIP protocol handler when
suspending and registering it back on resume.

* [PATCH 04/28] thunderbolt: Add dummy read after port capability list walk on Light Ridge

Light Ridge has an issue where reading the next capability pointer
location in port config space the read data is not cleared. It is fine
to read capabilities each after another so only thing we need to do is
to make sure we issue dummy read after tb_port_find_cap() is finished to
avoid the issue in next read.
