mlxsw: Avoid non-tracker helpers when holding and putting netdevices
Using the tracking helpers, netdev_hold() and netdev_put(), makes it easier
to debug netdevice refcount imbalances when CONFIG_NET_DEV_REFCNT_TRACKER
is enabled. For example, the following traceback shows the callpath to the
point of an outstanding hold that was never put:

In this patchset, get rid of all non-ref-tracking helpers in mlxsw.
- Patch #1 drops two functions that are not used anymore, but contain
dev_hold() / dev_put() calls.
- Patch #2 avoids taking a reference in one function which is called
under RTNL.
- The remaining patches convert individual hold/put sites one by one
from trackerless to tracker-enabled.

net: change accept_ra_min_rtr_lft to affect all RA lifetimes
accept_ra_min_rtr_lft only considered the lifetime of the default route
and discarded entire RAs accordingly.
This change renames accept_ra_min_rtr_lft to accept_ra_min_lft, and
applies the value to individual RA sections; in particular, router
lifetime, PIO preferred lifetime, and RIO lifetime. If any of those
lifetimes are lower than the configured value, the specific RA section
is ignored.
In order for the sysctl to be useful to Android, it should really apply
to all lifetimes in the RA, since that is what determines the minimum
frequency at which RAs must be processed by the kernel. Android uses
hardware offloads to drop RAs for a fraction of the minimum of all
lifetimes present in the RA (some networks have very frequent RAs (5s)
with high lifetimes (2h)). Despite this, we have encountered networks
that set the router lifetime to 30s which results in very frequent CPU
wakeups. Instead of disabling IPv6 (and dropping IPv6 ethertype in the
WiFi firmware) entirely on such networks, it seems better to ignore the
misconfigured routers while still processing RAs from other IPv6 routers
on the same network (i.e. to support IoT applications).
The previous implementation dropped the entire RA based on router
lifetime. This turned out to be hard to expand to the other lifetimes
present in the RA in a consistent manner; dropping the entire RA based
on RIO/PIO lifetimes would essentially require parsing the whole thing
twice.

net: store netdevs in an xarray
Iterating over the netdev hash table for netlink dumps is hard.
Dumps are done in "chunks" so we need to save the position
after each chunk, so we know where to restart from. Because
netdevs are stored in a hash table we remember which bucket
we were in and how many devices we dumped.
Since we don't hold any locks across the "chunks" - devices may
come and go while we're dumping. If that happens we may miss
a device (if device is deleted from the bucket we were in).
We indicate to user space that this may have happened by setting
NLM_F_DUMP_INTR. User space is supposed to dump again (I think)
if it sees that. Somehow I doubt most user space gets this right..
To illustrate let's look at an example:
System state:
start: # [A, B, C]
del: B # [A, C]
with the hash table we may dump [A, B], missing C completely even
tho it existed both before and after the "del B".
Add an xarray and use it to allocate ifindexes. This way we
can iterate ifindexes in order, without the worry that we'll
skip one. We may still generate a dump of a state which "never
existed", for example for a set of values and sequence of ops:
System state:
start: # [A, B]
add: C # [A, C, B]
del: B # [A, C]
we may generate a dump of [A], if C got an index between A and B.
System has never been in such state. But I'm 90% sure that's perfectly
fine, important part is that we can't _miss_ devices which exist before
and after. User space which wants to mirror kernel's state subscribes
to notifications and does periodic dumps so it will know that C exists
from the notification about its creation or from the next dump
(next dump is _guaranteed_ to include C, if it doesn't get removed).
To avoid any perf regressions keep the hash table for now. Most
net namespaces have very few devices and microbenchmarking 1M lookups
on Skylake I get the following results (not counting loopback
to number of devs):
#devs | hash | xa | delta
2 | 18.3 | 20.1 | + 9.8%
16 | 18.3 | 20.1 | + 9.5%
64 | 18.3 | 26.3 | +43.8%
128 | 20.4 | 26.3 | +28.6%
256 | 20.0 | 26.4 | +32.1%
1024 | 26.6 | 26.7 | + 0.2%
8192 |541.3 | 33.5 | -93.8%
No surprises since the hash table has 256 entries.
The microbenchmark scans indexes in order, if the pattern is more
random xa starts to win at 512 devices already. But that's a lot
of devices, in practice.

====================
Hello netdev-team,
this is a pull request of 21 patches for net-next/master.
The 1st patch is by Gerhard Uttenthaler, which adds Gerhard as the
maintainer ems_pci driver.
Peter Seiderer's patch removes a unused function from the peak_usb
driver.
The next 4 patches are by John Watts and add support for the sun4i_can
driver on the Allwinner D1.
Rob Herring's patch corrects the DT includes in various CAN drivers.
Followed by 14 patches from me concerning the gs_usb driver. The first
11 are various cleanups consisting of coding style improvements, error
path printout cleanups, and removal of unneeded
usb_kill_anchored_urbs(). The last 3 convert the driver to use NAPI to
avoid out-of-order reception of CAN frames.

====================
rxfh with custom RSS fixes
Greetings:
Welcome to v2, now via net-next. No functional changes; only style
changes (see the summary below).
While attempting to get the RX flow hash key for a custom RSS context on
my mlx5 NIC, I got an error:
$ sudo ethtool -u eth1 rx-flow-hash tcp4 context 1
Cannot get RX network flow hashing options: Invalid argument
I dug into this a bit and noticed two things:
1. ETHTOOL_GRXFH supports custom RSS contexts, but ETHTOOL_SRXFH does
not. I moved the copy logic out of ETHTOOL_GRXFH and into a helper so
that both ETHTOOL_{G,S}RXFH now call it, which fixes ETHTOOL_SRXFH. This
is patch 1/2.
2. mlx5 defaulted to RSS context 0 for both ETHTOOL_{G,S}RXFH paths. I
have modified the driver to support custom contexts for both paths. It
is now possible to get and set the flow hash key for custom RSS contexts
with mlx5. This is patch 2/2.
See commit messages for more details.
Thanks.
v2:
- Rebased on net-next
- Adjusted arguments of mlx5e_rx_res_rss_get_hash_fields and
mlx5e_rx_res_rss_set_hash_fields to move rss_idx next to the rss
argument
- Changed return value of both mlx5e_rx_res_rss_get_hash_fields and
mlx5e_rx_res_rss_set_hash_fields to -ENOENT when the rss entry is
NULL
- Changed order of local variables in mlx5e_get_rss_hash_opt and
mlx5e_set_rss_hash_opt

For example, before this patch attempting to retrieve the flow hash fields

Merge patch series "can: gs_usb: convert to NAPI"
Marc Kleine-Budde <mkl@pengutronix.de> says:
Traditionally USB drivers used netif_rx to pass the received CAN
frames/skbs to the network stack. In netif_rx() the skbs are queued to
the local CPU. If IRQs are handled in round robin, CAN frames may be
delivered out-of-order to user space.
To support devices without timestamping the TX path of the rx-offload
helper is cleaned up and extended:
- rename rx_offload_get_echo_skb() ->
can_rx_offload_get_echo_skb_queue_timestamp()
- add can_rx_offload_get_echo_skb_queue_tail()
The last patch converts the gs_usb driver to NAPI with the rx-offload

can: gs_usb: convert to NAPI/rx-offload to avoid OoO reception
The driver used to pass received CAN frames/skbs to the network stack
with netif_rx(). In netif_rx() the skbs are queued to the local CPU.
If IRQs are handled in round robin, OoO packets may occur.
To avoid out-of-order reception convert the driver from netif_rx() to
NAPI.
For USB devices with timestamping support use the rx-offload helper
can_rx_offload_queue_timestamp() for the RX, and
can_rx_offload_get_echo_skb_queue_timestamp() for the TX path. Devices
without timestamping support use can_rx_offload_queue_tail() for RX,
and can_rx_offload_get_echo_skb_queue_tail() for the TX path.

riscv: dts: allwinner: d1: Add CAN controller nodes
The Allwinner D1, T113 provide two CAN controllers that are variants
of the R40 controller.
I have tested support for these controllers on two boards:

net: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and

====================
net: stmmac: Increase clk_ptp_ref rate
This series aims to increase the clk_ptp_ref rate to get the best
possible PTP timestamping resolution possible. Some modified disclosure
about my development/testing process from the RFC/RFT v1 follows.
Disclosure: I don't know much about PTP beyond what you can google in an
afternoon, don't have access to documentation about the stmmac IP,
and have only tested that (based on code comments and git commit
history) the programming of the subsecond register (and the clock rate)
makes more sense with these changes. Qualcomm has tested a similar
change offlist, verifying PTP more formally as I understand it.
The last version was an RFC/RFT, but I didn't get a lot of confirmation
that doing patch 3 in that series (essentially setting clk_ptp_ref to
whatever its max value is) for the whole stmmac ecosystem was a safe
idea. So I am erring on the side of caution and doing this for the
Qualcomm platform only. See v1 for an approach that would apply to
all stmmac platform drivers with clk_ptp_ref.

TLS resets the protocol operations, so the read_sock() callback might
be changed, too.
In this case using sock->ops->readsock() in tls_strp_read_copyin() will
enter an infinite recursion if the read_sock() callback is calling
tls_rx_rec_wait() which will call into sock->ops->readsock() via
tls_strp_read_copyin().
But as tls_strp_read_copyin() is supposed to produce data from the
consumed socket and that socket is always a TCP socket we can call
tcp_read_sock() directly without having to deal with callbacks.
