====================
mlx5e-updates-2018-08-10
This series provides the following updates to mlx5e netdevice driver.
1) First 4 patches extends the support for ethtool rxnfc flow steering
- Added ipv6 support
- l4 proto ip field for both ip6 and ip4
2) Next 4 patches, reorganizing flow steering structures and declaration into
one header file, and add two Kconfig flags to allow disabling/enabling mlx5
netdevice rx flow steering at compile time:
CONFIG_MLX5_EN_ARFS for en_arfs.c
CONFIG_MLX5_EN_RXNFC for en_fs_ehtool.c
3) More kconfig flags dependencies
- vxlan.c depends on CONFIG_VXLAN
- clock.c depends on CONFIG_PTP_1588_CLOCK
4) Reorganize the Makefile
====================

Pull x86 cache QoS (RDT/CAR) updates from Thomas Gleixner:
"Add support for pseudo-locked cache regions.
Cache Allocation Technology (CAT) allows on certain CPUs to isolate a
region of cache and 'lock' it. Cache pseudo-locking builds on the fact
that a CPU can still read and write data pre-allocated outside its
current allocated area on cache hit. With cache pseudo-locking data
can be preloaded into a reserved portion of cache that no application
can fill, and from that point on will only serve cache hits. The cache
pseudo-locked memory is made accessible to user space where an
application can map it into its virtual address space and thus have a
region of memory with reduced average read latency.
The locking is not perfect and gets totally screwed by WBINDV and
similar mechanisms, but it provides a reasonable enhancement for
certain types of latency sensitive applications.
The implementation extends the current CAT mechanism and provides a
generally useful exclusive CAT mode on which it builds the extra
pseude-locked regions"

Lockdep reports deadlock for following locking scenario in ife action:
Task one:
1) Executes ife action update.
2) Takes tcfa_lock.
3) Waits on ife_mod_lock which is already taken by task two.
Task two:
1) Executes any path that obtains ife_mod_lock without disabling bh (any
path that takes ife_mod_lock while holding tcfa_lock has bh disabled) like
loading a meta module, or creating new action.
2) Takes ife_mod_lock.
3) Task is preempted by rate estimator timer.
4) Timer callback waits on tcfa_lock which is taken by task one.
In described case tasks deadlock because they take same two locks in
different order. To prevent potential deadlock reported by lockdep, always
disable bh when obtaining ife_mod_lock.

Pull RCU updates from Thomas Gleixner:
"A large update to RCU:
Preparatory work for consolidating the RCU flavors:
- Introduce grace-period sequence numbers to the RCU-bh, RCU-preempt,
and RCU-sched flavors, replacing the old ->gpnum and ->completed
pair of fields.
This change allows lockless code to obtain the complete
grace-period state with a single READ_ONCE(), which is needed to
maintain tolerable lock contention during the upcoming
consolidation of the three RCU flavors.
Note that grace-period sequence numbers are already used by
rcu_barrier(), expedited RCU grace periods, and SRCU, and are thus
already heavily used and well-tested. Joel Fernandes contributed a
number of excellent fixes and improvements.
- Clean up some grace-period-reporting loose ends, including
improving the handling of quiescent states from offline CPUs and
fixing some false-positive WARN_ON_ONCE() invocations.
(Strictly speaking, the WARN_ON_ONCE() invocations were quite
correct, but their invariants were (harmlessly) violated by the
earlier sloppy handling of quiescent states from offline CPUs.)
In addition, improve grace-period forward-progress guarantees so as
to allow removal of fail-safe checks that required otherwise
needless lock acquisitions. Finally, add more diagnostics to help
debug the upcoming consolidation of the RCU-bh, RCU-preempt, and
RCU-sched flavors.
The rest:
- SRCU updates
- Updates to rcutorture and associated scripting.
- The usual pile of miscellaneous fixes"

====================
pull-request: bpf-next 2018-08-13
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add driver XDP support for veth. This can be used in conjunction with
redirect of another XDP program e.g. sitting on NIC so the xdp_frame
can be forwarded to the peer veth directly without modification,
from Toshiaki.
2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT
in order to provide more control and visibility on where a SO_REUSEPORT
sk should be located, and the latter enables to directly select a sk
from the bpf map. This also enables map-in-map for application migration
use cases, from Martin.
3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id
of cgroup v2 that is the ancestor of the cgroup associated with the
skb at the ancestor_level, from Andrey.
4) Implement BPF fs map pretty-print support based on BTF data for regular
hash table and LRU map, from Yonghong.
5) Decouple the ability to attach BTF for a map from the key and value
pretty-printer in BPF fs, and enable further support of BTF for maps for
percpu and LPM trie, from Daniel.
6) Implement a better BPF sample of using XDP's CPU redirect feature for
load balancing SKB processing to remote CPU. The sample implements the
same XDP load balancing as Suricata does which is symmetric hash based
on IP and L4 protocol, from Jesper.
7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s
critical path as it is ensured that the allocator is present, from Björn.

The patches includes following change:
*Use modern kvzalloc()/kvfree() instead of custom allocations.
*Remove order argument for alloc_pg_vec, it can get from req.
*Remove order argument for free_pg_vec, free_pg_vec now uses
kvfree which does not need order argument.
*Remove pg_vec_order from struct packet_ring_buffer, no longer
need to save/restore 'order'
*Remove variable 'order' for packet_set_ring, it is now unused

There is an unalignment access about the structure
'trace_event_raw_fib_table_lookup'.
In include/trace/events/fib.h, there is a memory operation which casting
the 'src' data member to a pointer, and then store a value to this
pointer point to.
p32 = (__be32 *) __entry->src;
*p32 = flp->saddr;
The offset of 'src' in structure trace_event_raw_fib_table_lookup is not
four bytes alignment. On some architectures, they don't permit the
unalignment access, it need to pay the price to handle this situation in
exception handler.
Adjust the layout of structure to avoid this case.

Jamal Hadi Salim says:
====================
net: sched: actions rename for grep-ability and consistency
Having a structure (example tcf_mirred) and a function with the same name is
not good for readability or grepability.
This long overdue patchset improves it and make sure there is consistency
across all actions
