'net-core-unify-dstats-with-tstats-and-lstats-implement-generic-dstats-collection'
Jeremy Kerr says:
====================
net: core: Unify dstats with tstats and lstats, implement generic dstats collection
The struct pcpu_dstats ("dstats") has a few variations from the other
two stats types (struct pcpu_sw_netstats and struct pcpu_lstats), and
doesn't have generic helpers for collecting the per-cpu stats into a
struct rtnl_link_stats64.
This change unifies dstats with the other types, adds a collection
implementation to the core, and updates the single driver (vrf) to use
this generic implementation.
Of course, questions/comments/etc are most welcome!

The vrf driver has its own dstats-to-rtnl_link_stats64 collection, but
we now have a generic implementation for dstats collection, so switch to
this.
In doing so, we fix a minor issue where the (non-percpu)
dev->stats->tx_errors value was never collected into rtnl_link_stats64,
as the generic dev_get_dstats64() consumes the starting values from
dev->stats.

We currently have dev_get_tstats64() for collecting per-cpu stats of
type pcpu_sw_netstats ("tstats"). However, tstats doesn't allow for
accounting tx/rx drops. We do have a stats variant that does have stats
for dropped packets: struct pcpu_dstats, but there are no core helpers
for using those stats.
The VRF driver uses dstats, by providing its own collation/fetch
functions to do so.
This change adds a common implementation for dstats-type collection,
used when pcpu_stat_type == NETDEV_PCPU_STAT_DSTAT. This is based on the
VRF driver's existing stats collator (plus the unused tx_drops stat from
there). We will switch the VRF driver to use this in the next change.

The pcpu_sw_netstats and pcpu_lstats structs both contain a set of
u64_stats_t fields for individual stats, but pcpu_dstats uses u64s
instead.
Make this consistent by using u64_stats_t across all stats types.
The per-cpu dstats are only used by the vrf driver at present, so update
that driver as part of this change.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core instead
of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Move ip_tunnel driver to leverage the core allocation.
All the ip_tunnel_init() users call ip_tunnel_init() as part of their
.ndo_init callback. The .ndo_init callback is called before the stats
allocation in netdev_register(), thus, the allocation will happen before
the netdev is visible.

'ip6 dscp set $v' in an nftables outpute route chain has no effect.
While nftables does detect the dscp change and calls the reroute hook.
But ip6_route_me_harder never sets the dscp/flowlabel:
flowlabel/dsfield routing rules are ignored and no reroute takes place.

Lion Ackermann reported that there is a race condition between namespace cleanup
in ipset and the garbage collection of the list:set type. The namespace
cleanup can destroy the list:set type of sets while the gc of the set type is
waiting to run in rcu cleanup. The latter uses data from the destroyed set which
thus leads use after free. The patch contains the following parts:
- When destroying all sets, first remove the garbage collectors, then wait
if needed and then destroy the sets.
- Fix the badly ordered "wait then remove gc" for the destroy a single set
case.
- Fix the missing rcu locking in the list:set type in the userspace test
case.
- Use proper RCU list handlings in the list:set type.
The patch depends on c1193d9bbbd3 (netfilter: ipset: Add list flush to cancel_gc).

====================
Intel Wired LAN Driver Updates 2024-06-03
This series includes miscellaneous improvements for the ice as well as a
cleanup to the Makefiles for all Intel net drivers.
Andy fixes all of the Intel net driver Makefiles to use the documented
'*-y' syntax for specifying object files to link into kernel driver
modules, rather than the '*-objs' syntax which works but is documented as
reserved for user-space host programs.
Jacob has a cleanup to refactor rounding logic in the ice driver into a
common roundup_u64 helper function.
Michal Schmidt replaces irq_set_affinity_hint() to use
irq_update_affinity_hint() which behaves better with user-applied affinity
settings.

irq_set_affinity_hint() is deprecated. Use irq_update_affinity_hint()
instead. This removes the side-effect of actually applying the affinity.
The driver does not really need to worry about spreading its IRQs across
CPUs. The core code already takes care of that.
On the contrary, when the driver applies affinities by itself, it breaks
the users' expectations:
1. The user configures irqbalance with IRQBALANCE_BANNED_CPULIST in
order to prevent IRQs from being moved to certain CPUs that run a
real-time workload.
2. ice reconfigures VSIs at runtime due to a MIB change
(ice_dcb_process_lldp_set_mib_change). Reopening a VSI resets the
affinity in ice_vsi_req_irq_msix().
3. ice has no idea about irqbalance's config, so it may move an IRQ to
a banned CPU. The real-time workload suffers unacceptable latency.
I am not sure if updating the affinity hints is at all useful, because
irqbalance ignores them since 2016 ([1]), but at least it's harmless.
This ice change is similar to i40e commit d34c54d1739c ("i40e: Use
irq_update_affinity_hint()").

In ice_ptp_cfg_clkout(), the ice driver needs to calculate the nearest next
second of a current time value specified in nanoseconds. It implements this
using div64_u64, because the time value is a u64. It could use div_u64
since NSEC_PER_SEC is smaller than 32-bits.
Ideally this would be implemented directly with roundup(), but that can't
work on all platforms due to a division which requires using the specific
macros and functions due to platform restrictions, and to ensure that the
most appropriate and fast instructions are used.
The kernel doesn't currently provide any 64-bit equivalents for doing
roundup. Attempting to use roundup() on a 32-bit platform will result in a
link failure due to not having a direct 64-bit division.
The closest equivalent for this is DIV64_U64_ROUND_UP, which does a
division always rounding up. However, this only computes the division, and
forces use of the div64_u64 in cases where the divisor is a 32bit value and
could make use of div_u64.
Introduce DIV_U64_ROUND_UP based on div_u64, and then use it to implement
roundup_u64 which takes a u64 input value and a u32 rounding value.
The name roundup_u64 matches the naming scheme of div_u64, and future
patches could implement roundup64_u64 if they need to round by a multiple
that is greater than 32-bits.
Replace the logic in ice_ptp.c which does this equivalent with the newly
added roundup_u64.

Due to timer wheel implementation, a timer will usually fire
after its schedule.
For instance, for HZ=1000, a timeout between 512ms and 4s
has a granularity of 64ms.
For this range of values, the extra delay could be up to 63ms.
For TCP, this means that tp->rcv_tstamp may be after
inet_csk(sk)->icsk_timeout whenever the timer interrupt
finally triggers, if one packet came during the extra delay.
We need to make sure tcp_rtx_probe0_timed_out() handles this case.

fallback to TCP followed by retransmissions before the processing of
any other incoming packets. A fix for v5.9+.
- Patch 2 makes sure the RmAddr MIB counter is incremented, and only
once per ID, upon the reception of a RM_ADDR. A fix for v5.10+.
- Patch 3 doesn't update 'add addr' related counters if the connect()
was not possible. A fix for v5.7+.
- Patch 4 updates the mailmap file to add Geliang's new email address.

The creation of new subflows can fail for different reasons. If no
subflow have been created using the received ADD_ADDR, the related
counters should not be updated, otherwise they will never be decremented
for events related to this ID later on.
For the moment, the number of accepted ADD_ADDR is only decremented upon
the reception of a related RM_ADDR, and only if the remote address ID is
currently being used by at least one subflow. In other words, if no
subflow can be created with the received address, the counter will not
be decremented. In this case, it is then important not to increment
pm.add_addr_accepted counter, and not to modify pm.accept_addr bit.
Note that this patch does not modify the behaviour in case of failures
later on, e.g. if the MP Join is dropped or rejected.
The "remove invalid addresses" MP Join subtest has been modified to
validate this case. The broadcast IP address is added before the "valid"
address that will be used to successfully create a subflow, and the
limit is decreased by one: without this patch, it was not possible to
create the last subflow, because:
- the broadcast address would have been accepted even if it was not
usable: the creation of a subflow to this address results in an error,
- the limit of 2 accepted ADD_ADDR would have then been reached.

The RmAddr MIB counter is supposed to be incremented once when a valid
RM_ADDR has been received. Before this patch, it could have been
incremented as many times as the number of subflows connected to the
linked address ID, so it could have been 0, 1 or more than 1.
The "RmSubflow" is incremented after a local operation. In this case,
it is normal to tied it with the number of subflows that have been
actually removed.
The "remove invalid addresses" MP Join subtest has been modified to
validate this case. A broadcast IP address is now used instead: the
client will not be able to create a subflow to this address. The
consequence is that when receiving the RM_ADDR with the ID attached to
this broadcast IP address, no subflow linked to this ID will be found.

When the noop_qdisc owner isn't initialized, then it will be 0,
so packets will erroneously be regarded as having been subject
to recursion as long as only CPU 0 queues them. For non-SMP,
that's all packets, of course. This causes a change in what's
reported to userspace, normally noop_qdisc would drop packets
silently, but with this change the syscall returns -ENOBUFS if
RECVERR is also set on the socket.
Fix this by initializing the owner field to -1, just like it
would be for dynamically allocated qdiscs by qdisc_alloc().

We use the polling interface to srcu for tracking pending frees; when
shutting down we don't need to wait for an srcu barrier to free them,
but SRCU still gets confused if we shutdown with an outstanding grace

The amp_id argument of l2cap_connect() was removed in
commit 84a4bb6548a2 ("Bluetooth: HCI: Remove HCI_AMP support")
It was always called with amp_id == 0, i.e. AMP_ID_BREDR == 0x00 (ie.
non-AMP controller). In the above commit, the code path for amp_id != 0
was preserved, although it should have used the amp_id == 0 one.
Restore the previous behavior of the non-AMP code path, to fix problems
with L2CAP connections.

Fix changing DSA conduit
This series fixes an issue in the DSA code related to host interface UC
address installed into port FDB and port conduit address database when
live-changing port conduit.
The first patch refactores/deduplicates the installation/uninstallation
of the interface's MAC address and the second patch fixes the issue.

When changing DSA user interface conduit while the user interface is up,
DSA exhibits different behavior in comparison to when the interface is
down. This different behavior concerns the primary unicast MAC address
stored in the port standalone FDB and in the conduit device UC database.
If we put a switch port down while changing the conduit with
ip link set sw0p0 down
ip link set sw0p0 type dsa conduit conduit1
ip link set sw0p0 up
we delete the address in dsa_user_close() and install the (possibly
different) address in dsa_user_open().
But when changing the conduit on the fly, the old address is not
deleted and the new one is not installed.
Since we explicitly want to support live-changing the conduit, uninstall
the old address before calling dsa_port_assign_conduit() and install the
(possibly different) new address after the call.
Because conduit change might also trigger address change (the user
interface is supposed to inherit the conduit interface MAC address if no
address is defined in hardware (dp->mac is a zero address)), move the
eth_hw_addr_inherit() call from dsa_user_change_conduit() to
dsa_port_change_conduit(), just before installing the new address.
Although this is in theory a flaw in DSA core, it needs not be
backported, since there is currently no DSA driver that can be affected
by this. The only DSA driver that supports changing conduit is felix,
and, as explained by Vladimir Oltean [1]:
There are 2 reasons why with felix the bug does not manifest itself.
First is because both the 'ocelot' and the alternate 'ocelot-8021q'
tagging protocols have the 'promisc_on_conduit = true' flag. So the
unicast address doesn't have to be in the conduit's RX filter -
neither the old or the new conduit.
Second, dsa_user_host_uc_install() theoretically leaves behind host
FDB entries installed towards the wrong (old) CPU port. But in
felix_fdb_add(), we treat any FDB entry requested towards any CPU port
as if it was a multicast FDB entry programmed towards _all_ CPU ports.
For that reason, it is installed towards the port mask of the PGID_CPU
port group ID:
if (dsa_port_is_cpu(dp))
port = PGID_CPU;
Therefore no Fixes tag for this change.

The sequence
if (dsa_switch_supports_uc_filtering(ds))
dsa_port_standalone_host_fdb_add(dp, addr, 0);
if (!ether_addr_equal(addr, conduit->dev_addr))
dev_uc_add(conduit, addr);
is executed both in dsa_user_open() and dsa_user_set_mac_addr().
Its reverse is executed both in dsa_user_close() and
dsa_user_set_mac_addr().
Refactor these sequences into new functions dsa_user_host_uc_install()
and dsa_user_host_uc_uninstall().

Move the vxlan_features_check() call to after we verified the packet is
a tunneled VXLAN packet.
Without this, tunneled UDP non-VXLAN packets (for ex. GENENVE) might
wrongly not get offloaded.
In some cases, it worked by chance as GENEVE header is the same size as
VXLAN, but it is obviously incorrect.
