I don't think there is any problem with switching to faster code
immediately, as long as we have data that supports the claim that it
is actually faster on hardware people care about. The arm64 ChaCha20
code in the kernel is slower than the OpenSSL code as far as I know,
so I have no problems whatsoever with dropping it. The ARM version,
however, is slower on Cortex-A7 (according to Eric's benchmarks),
which is the only 32-bit ARM core anybody cares about these days.

* [PATCH v3 net-next] ravb: do not write 1 to reserved bits
From: Simon Horman @ 2018-09-18 10:22 UTC (permalink / raw)
To: David Miller, Sergei Shtylyov; +Cc: Magnus Damm, netdev, linux-renesas-soc
From: Kazuya Mizuguchi <kazuya.mizuguchi.ks@renesas.com>
EtherAVB hardware requires 0 to be written to status register bits in
order to clear them, however, care must be taken not to:
1. Clear other bits, by writing zero to them
2. Write one to reserved bits
This patch corrects the ravb driver with respect to the second point above.
This is done by defining reserved bit masks for the affected registers and,
after auditing the code, ensure all sites that may write a one to a
reserved bit use are suitably masked.

STMMAC already supports 4.21a and 5.10a. You only have to make
sure that your regbank and descriptors matches.

* [PATCH bpf-next 2/2] xsk: fix bug when trying to use both copy and zero-copy on one queue id
From: Magnus Karlsson @ 2018-09-18 10:12 UTC (permalink / raw)
To: magnus.karlsson, bjorn.topel, ast, daniel, netdev
In-Reply-To: <1537265538-5882-1-git-send-email-magnus.karlsson@intel.com>
Previously, the xsk code did not record which umem was bound to a
specific queue id. This was not required if all drivers were zero-copy
enabled as this had to be recorded in the driver anyway. So if a user
tried to bind two umems to the same queue, the driver would say
no. But if copy-mode was first enabled and then zero-copy mode (or the
reverse order), we mistakenly enabled both of them on the same umem
leading to buggy behavior. The main culprit for this is that we did
not store the association of umem to queue id in the copy case and
only relied on the driver reporting this. As this relation was not
stored in the driver for copy mode (it does not rely on the AF_XDP
NDOs), this obviously could not work.
This patch fixes the problem by always recording the umem to queue id
relationship in the netdev_queue and netdev_rx_queue structs. This way
we always know what kind of umem has been bound to a queue id and can
act appropriately at bind time.

Patch 1: Introduces a umem reference in the netdev_rx_queue and

Patch 2: Records which queue_id is bound to which umem and make sure
that you cannot bind two different umems to the same queue_id.
I based this patch set on bpf-next commit 70e88c758a6b

* [PATCH iproute2] iplink: fix incorrect any address handling for ip tunnels
From: Hangbin Liu @ 2018-09-18 9:48 UTC (permalink / raw)
To: netdev
Cc: Stephen Hemminger, David Ahern, Phil Sutter, Serhey Popovych,

After commit d42c7891d26e4 ("utils: Do not reset family for default, any,
all addresses"), when call get_addr() for any/all addresses, we will set
addr->flags to ADDRTYPE_INET_UNSPEC if family is AF_INET/AF_INET6, which
makes is_addrtype_inet() checking passed and assigns incorrect address
to kernel. The ip link cmd will return error like:
]# ip link add ipip1 type ipip local any remote 1.1.1.1
RTNETLINK answers: Numerical result out of range
Fix it by using is_addrtype_inet_not_unspec() to avoid unspec addresses.
geneve, vxlan are not affected as they use AF_UNSPEC family when call
get_addr()

* [PATCH net] net: mvpp2: fix a txq_done race condition
From: Antoine Tenart @ 2018-09-18 14:58 UTC (permalink / raw)
To: davem
Cc: Antoine Tenart, netdev, linux-kernel, thomas.petazzoni,
maxime.chevallier, gregory.clement, miquel.raynal, nadavh,
stefanc, ymarkman, mw
When no Tx IRQ is available, the txq_done() routine (called from
tx_done()) shouldn't be called from the polling function, as in such
case it is already called in the Tx path thanks to an hrtimer. This
mostly occurred when using PPv2.1, as the engine then do not have Tx
IRQs.
Fixes: edc660fa09e2 ("net: mvpp2: replace TX coalescing interrupts with hrtimer")

Sorry, I do not understand how phy-handle point to MDIO controller,
because phy-handle is defined to point to a phy.
I suppose you mean:
mdio_node = of_get_parent(phy_node);
emac0: ethernet@feb20000 {
phy-handle = <&phy0>;
mdio {
#address-cells = <1>;
#size-cells = <0>;
phy0: ethernet-phy@0 {
reg = <0>;
};
phy1: ethernet-phy@1 {
reg = <1>;
};
};
};
emac1: ethernet@fexxxxxx {
phy-handle = <&phy1>;
};
emac2: ethernet@fexxxxxx {
phy-handle = <&phy2>;
mdio {
#address-cells = <1>;
#size-cells = <0>;
phy2: ethernet-phy@2 {
reg = <0>;
};
};
};

* pegged softirq and NAPI race (?)
From: Song Liu @ 2018-09-18 8:41 UTC (permalink / raw)
To: Networking
Cc: edumazet@google.com, jeffrey.t.kirsher@intel.com,
alexander.h.duyck@intel.com, Michael Chan, Kernel Team
We are debugging this issue that netconsole message triggers pegged softirq
(ksoftirqd taking 100% CPU for many seconds). We found this issue in
production with both bnxt and ixgbe, on a 4.11 based kernel. This is easily
reproducible with ixgbe on 4.11, and latest net/net-next (see [1] for more
detail).
After debugging for some time, we found that this issue is likely related
to 39e6c8208d7b ("net: solve a NAPI race"). After reverting this commit,
the steps described in [1] cannot reproduce the issue on ixgbe. Reverting
this commit also reduces the chances we hit the issue with bnxt (it still
happens with a lower rate).
I tried to fix this issue with relaxed variant (or older version) of
napi_schedule_prep() in netpoll, just like the one on napi_watchdog().
However, my tests do not always go as expected.
Please share your comments/suggestions on which direction shall we try
to fix this.
Thanks in advance!

Hi David, I see this was applied to net-next tree only.
Can we have it in net? We consider it as critical flaw.

> Thanks Eric for reviewing the patch. rtnl_needed is not a shared variable, it is part of bonding structure, that is one per bonding driver instance. There can't be two parallel instances of bond_miimon_inspect for a single bonding driver instance at any given point of time. and only bond_miimon_inspect updates it. That’s why I think there is no need of any synchronization here.

If rtnl_trylock() can not grab RTNL,
there is no way the current thread can set the variable without a race, if the word including rtnl_needed is shared by other fields in the structure.
Your patch adds a subtle possibility of future bugs, even if it runs fine today.
Do not pave the way for future bugs, make your code robust, please.

No need, I have it already in perf/urgent, will push shortly to Ingo.

Not sure it would be a natural fit. DIM doesn't know/care which type of
timer is used. Maybe the two mechanisms can work together with DIM
optimizes the number of frames to use for optimal coalescing. As the
timer is set to 1ms, DIM would have issues suggesting meaningful values
as it is designed for typical values of 10s on us.

Maybe time to introduce kernel side access-control flags?
Read/Write permissions for example. Attrs marked as read only
(in the kernel) cannot be written to.

Thanks Sergei,
I agree GENMASK() without any cast should be sufficient in all
of the above cases. I'll respin accordingly.

My (very own personal) preference in general would be that we test / assert
the kernel behavior that exists /today/, meaning once we implement support
for multi-record peek we add the corresponding test case along with that
code. Fwiw, this practice would be consistent with the rest of the kernel
selftests development model we have under net (& bpf).
Thanks,
Daniel
