Quoting Ilan Tayari:
1. Set up a host-to-host IPSec tunnel (or transport, doesn't matter)
2. Ping over IPSec, or do something to populate the pcpu cache
3. Join a MC group, then leave MC group
4. Try to ping again using same CPU as before -> traffic
doesn't egress the machine at all
Ilan debugged the problem down to the fact that one of the path dsts
devices point to lo due to earlier dst_dev_put().
In this case, dst is marked as DEAD and we cannot reuse the bundle.
The cache only asserted that the requested policy and that of the cached
bundle match, but its not enough - also verify the path is still valid.

Refactor lan9303_xxx_packet_processing
This series is purely non functional.
It changes the lan9303_enable_packet_processing,
lan9303_disable_packet_processing() to pass port number (0,1,2) as
parameter instead of port offset. This aligns them with
other functions in the module, and makes it possible to simplify the code.
The lan9303_enable_packet_processing, lan9303_disable_packet_processing
functions operate on port. Therefore rename the functions to reflect that
as well.
Reviewer pointed out lan9303_get_ethtool_stats would be better off with
the use of a lan9303_read_switch_port(). So that was added to the series.
Changes v3 -> v4:
- Whitespace adjustments.
Changes v2 -> v3:
- Patch 1: Removed the change in lan9303_get_ethtool_stats
- Added patch 4: rename lan9303_xxx_packet_processing
- Added patch 5: refactor lan9303_get_ethtool_stats
Changes v1 -> v2:
- introduced lan9303_write_switch_port() in first patch
- inserted LAN9303_NUM_PORTS patch
- Use LAN9303_NUM_PORTS in last patch. Plus whitespace change.

David Lebrun says:
====================
ipv6: sr: add support for advanced local segment processing
v2: use EXPORT_SYMBOL_GPL
The current implementation of IPv6 SR supports SRH insertion/encapsulation
and basic segment endpoint behavior (i.e., processing of an SRH contained in
a packet whose active segment (IPv6 DA) is routed to the local node). This
behavior simply consists of updating the DA to the next segment and forwarding
the packet accordingly. This processing is realised for all such packets,
regardless of the active segment.
The most recent specifications of IPv6 SR [1] [2] extend the SRH processing
features as follows. Each segment endpoint defines a MyLocalSID table.
This table maps segments to operations to perform. For each ingress IPv6
packet whose DA is part of a given prefix, the segment endpoint looks
up the active segment (i.e., the IPv6 DA) in the MyLocalSID table and
applies the corresponding operation. Such specifications enable to specify
arbitrary operations besides the basic SRH processing and allow for a more
fine-grained classification.
This patch series implements those extended specifications by leveraging
a new type of lightweight tunnel, seg6local. The MyLocalSID table is
simply an arbitrary routing table (using CONFIG_IPV6_MULTIPLE_TABLES). The
following commands would assign the prefix fc00::/64 to the MyLocalSID
table, map the segment fc00::42 to the regular SRH processing function
(named "End"), and drop all packets received with an undefined active
segment:
ip -6 rule add fc00::/64 lookup 100
ip -6 route add fc00::42 encap seg6local action End dev eth0 table 100
ip -6 route add blackhole default table 100
As another example, the following command would assign the segment
fc00::1234 to the regular SRH processing function, except that the
processed packet must be forwarded to the next-hop fc42::1 (this operation
is named "End.X"):
ip -6 route add fc00::1234 encap seg6local action End.X nh6 fc42::1 dev eth0 table 100
Those two basic operations (End and End.X) are defined in [1]. A more
extensive list of advanced operations is defined in [2].
The first two patches of the series are preliminary work that remove an
assumption about initial SRH format, and export the two functions used to
insert and encapsulate an SRH onto packets. The third patch defines the
new seg6local lightweight tunnel and implement the core functions. The
fourth patch implements the operations needed to handle the newly defined
rtnetlink attributes. The fifth patch implements a few SRH processing
operations, including End and End.X.

This patch implements the following seg6local actions.
- SEG6_LOCAL_ACTION_END: regular SRH processing. The DA of the packet
is updated to the next segment and forwarded accordingly.
- SEG6_LOCAL_ACTION_END_X: same as above, except that the packet is
forwarded to the specified IPv6 next-hop.
- SEG6_LOCAL_ACTION_END_DX6: decapsulate the packet and forward to
inner IPv6 packet to the specified IPv6 next-hop.
- SEG6_LOCAL_ACTION_END_B6: insert the specified SRH directly after
the IPv6 header of the packet.
- SEG6_LOCAL_ACTION_END_B6_ENCAP: encapsulate the packet within
an outer IPv6 header, containing the specified SRH.

This patch implements a new type of lightweight tunnel named seg6local.
A seg6local lwt is defined by a type of action and a set of parameters.
The action represents the operation to perform on the packets matching the
lwt's route, and is not necessarily an encapsulation. The set of parameters
are arguments for the processing function.
Each action is defined in a struct seg6_action_desc within
seg6_action_table[]. This structure contains the action, mandatory
attributes, the processing function, and a static headroom size required by
the action. The mandatory attributes are encoded as a bitmask field. The
static headroom is set to a non-zero value when the processing function
always add a constant number of bytes to the skb (e.g. the header size for
encapsulations).
To facilitate rtnetlink-related operations such as parsing, fill_encap,
and cmp_encap, each type of action parameter is associated to three
function pointers, in seg6_action_params[].
All actions defined in seg6_local.h are detailed in [1].

This patch enables to insert SRHs with an arbitrary active segment.

Originally we used a mutex to protect concurrent devmap update
and delete operations from racing with netdev unregister notifier
callbacks.
The notifier hook is needed because we increment the netdev ref
count when a dev is added to the devmap. This ensures the netdev
reference is valid in the datapath. However, we don't want to block
unregister events, hence the initial mutex and notifier handler.
The concern was in the notifier hook we search the map for dev
entries that hold a refcnt on the net device being torn down. But,
in order to do this we require two steps,
(i) dereference the netdev: dev = rcu_dereference(map[i])
(ii) test ifindex: dev->ifindex == removing_ifindex
and then finally we can swap in the NULL dev in the map via an
xchg operation,
xchg(map[i], NULL)
The danger here is a concurrent update could run a different
xchg op concurrently leading us to replace the new dev with a
NULL dev incorrectly.
CPU 1 CPU 2
notifier hook bpf devmap update
dev = rcu_dereference(map[i])
dev = rcu_dereference(map[i])
xchg(map[i]), new_dev);
rcu_call(dev,...)
xchg(map[i], NULL)
The above flow would create the incorrect state with the dev
reference in the update path being lost. To resolve this the
original code used a mutex around the above block. However,
updates, deletes, and lookups occur inside rcu critical sections
so we can't use a mutex in this context safely.
Fortunately, by writing slightly better code we can avoid the
mutex altogether. If CPU 1 in the above example uses a cmpxchg
and _only_ replaces the dev reference in the map when it is in
fact the expected dev the race is removed completely. The two
cases being illustrated here, first the race condition,
CPU 1 CPU 2
notifier hook bpf devmap update
dev = rcu_dereference(map[i])
dev = rcu_dereference(map[i])
xchg(map[i]), new_dev);
rcu_call(dev,...)
odev = cmpxchg(map[i], dev, NULL)
Now we can test the cmpxchg return value, detect odev != dev and
abort. Or in the good case,
CPU 1 CPU 2
notifier hook bpf devmap update
dev = rcu_dereference(map[i])
odev = cmpxchg(map[i], dev, NULL)
[...]
Now 'odev == dev' and we can do proper cleanup.
And viola the original race we tried to solve with a mutex is
corrected and the trace noted by Sasha below is resolved due
to removal of the mutex.
Note: When walking the devmap and removing dev references as needed
we depend on the core to fail any calls to dev_get_by_index() using
the ifindex of the device being removed. This way we do not race with
the user while searching the devmap.
Additionally, the mutex was also protecting list add/del/read on
the list of maps in-use. This patch converts this to an RCU list
and spinlock implementation. This protects the list from concurrent
alloc/free operations. The notifier hook walks this list so it uses
RCU read semantics.

Currently, bpf programs cannot be attached to sys_enter_* and sys_exit_*
style tracepoints. The iovisor/bcc issue #748
(https://github.com/iovisor/bcc/issues/748) documents this issue.
For example, if you try to attach a bpf program to tracepoints
syscalls/sys_enter_newfstat, you will get the following error:
# ./tools/trace.py t:syscalls:sys_enter_newfstat
Ioctl(PERF_EVENT_IOC_SET_BPF): Invalid argument
Failed to attach BPF to tracepoint
The main reason is that syscalls/sys_enter_* and syscalls/sys_exit_*
tracepoints are treated differently from other tracepoints and there
is no bpf hook to it.
This patch adds bpf support for these syscalls tracepoints by
. permitting bpf attachment in ioctl PERF_EVENT_IOC_SET_BPF
. calling bpf programs in perf_syscall_enter and perf_syscall_exit
The legality of bpf program ctx access is also checked.
Function trace_event_get_offsets returns correct max offset for each
specific syscall tracepoint, which is compared against the maximum offset
access in bpf program.

net: l3mdev: Support for sockets bound to enslaved device
A missing piece to the VRF puzzle is the ability to bind sockets to
devices enslaved to a VRF. This patch set adds the enslaved device
index, sdif, to IPv4 and IPv6 socket lookups. The end result for users
is the following scope options for services:
1. "global" services - sockets not bound to any device
Allows 1 service to work across all network interfaces with
connected sockets bound to the VRF the connection originates
(Requires net.ipv4.tcp_l3mdev_accept=1 for TCP and
net.ipv4.udp_l3mdev_accept=1 for UDP)
2. "VRF" local services - sockets bound to a VRF
Sockets work across all network interfaces enslaved to a VRF but
are limited to just the one VRF.
3. "device" services - sockets bound to a specific network interface
Service works only through the one specific interface.
v3
- convert __inet_lookup_established in dccp_v4_err; missed in v2
v2
- remove sk_lookup struct and add sdif as an argument to existing
functions

The #ifdefs in this driver are obviously wrong, so this just
removes them and uses an IS_ENABLED() check that does the same
thing correctly in a more readable way.

Saeed Mahameed says:
====================
mlx5-shared-2017-08-07
This series includes some mlx5 updates for both net-next and rdma trees.
From Saeed,
Core driver updates to allow selectively building the driver with
or without some large driver components, such as
- E-Switch (Ethernet SRIOV support).
- Multi-Physical Function Switch (MPFs) support.
For that we split E-Switch and MPFs functionalities into separate files.
From Erez,
Delay mlx5_core events when mlx5 interfaces, namely mlx5_ib, registration
is taking place and until it completes.
From Rabie,
Increase the maximum supported flow counters.

net: sched: summer cleanup part 2, ndo_setup_tc
This patchset focuses on ndo_setup_tc and its args.
Currently there are couple of things that do not make much sense.
The type is passed in struct tc_to_netdev, but as it is always
required, should be arg of the ndo. Other things are passed as args
but they are only relevant for cls offloads and not mqprio. Therefore,
they should be pushed to struct. As the tc_to_netdev struct in the end
is just a container of single pointer, we get rid of it and pass the
struct according to type. So in the end, we have:
ndo_setup_tc(dev, type, type_data_struct)
There are couple of cosmetics done on the way to make things smooth.
Also, reported error is consolidated to eopnotsupp in case the
asked offload is not supported.
v1->v2:
- added forgotten hns3pf bits

Get rid of struct tc_to_netdev which is now just unnecessary container
and rather pass per-type structures down to drivers directly.
Along with that, consolidate the naming of per-type structure variables
in cls_*.

Change the return value from -EINVAL to -EOPNOTSUPP. The rest of the
drivers have it like that, so be aligned.

prio is not cls_flower specific, but it is meaningful for all
classifiers. Seems that only mlxsw cares about the value. Obviously,
cls offload in other drivers is broken.

As ndo_setup_tc is generic offload op for whole tc subsystem, does not
really make sense to have cls-specific args. So move them under
cls_common structurure which is embedded in all cls structs.

Change the flows a bit in preparation of follow-up changes in
ndo_setup_tc args. Also, change the error code to align with the rest of
the drivers.
