ec527c3180 x86/power: Fix 'nosmt' vs hibernation triple fault during resume
As explained in

	0cc3cd2165 ("cpu/hotplug: Boot HT siblings at least once")

we always, no matter what, have to bring up x86 HT siblings during boot at
least once in order to avoid first MCE bringing the system to its knees.

That means that whenever 'nosmt' is supplied on the kernel command-line,
all the HT siblings are as a result sitting in mwait or cpudile after
going through the online-offline cycle at least once.

This causes a serious issue though when a kernel, which saw 'nosmt' on its
commandline, is going to perform resume from hibernation: if the resume
from the hibernated image is successful, cr3 is flipped in order to point
to the address space of the kernel that is being resumed, which in turn
means that all the HT siblings are all of a sudden mwaiting on address
which is no longer valid.

That results in triple fault shortly after cr3 is switched, and machine
reboots.

Fix this by always waking up all the SMT siblings before initiating the
'restore from hibernation' process; this guarantees that all the HT
siblings will be properly carried over to the resumed kernel waiting in
resume_play_dead(), and acted upon accordingly afterwards, based on the
target kernel configuration.

Symmetricaly, the resumed kernel has to push the SMT siblings to mwait
again in case it has SMT disabled; this means it has to online all
the siblings when resuming (so that they come out of hlt) and offline
them again to let them reach mwait.

ef11db3310 net: inetdevice: provide replacement iterators for in_ifaddr walk
The ifa_list is protected either by rcu or rtnl lock, but the
current iterators do not account for this.

This adds two iterators as replacement, a later patch in

Its not done in this patch yet to avoid sparse warnings -- the fields

8a7e8ff8ce isdn: deprecate non-mISDN drivers
When isdn4linux came up in the context of another patch series, I
 remembered that we had discussed removing it a while ago.
 
 It turns out that the suggestion from Karsten Keil wa to remove I4L
 in 2018 after the last public ISDN networks are shut down. This has
 happened now (with a very small number of exceptions), so I guess it's
 time to try again.
 
 We currently have three ISDN stacks in the kernel: the original
 isdn4linux (with the hisax driver), the newer CAPI (with four drivers),
 and finally the mISDN stack (supporting roughly the same hardware as
 hisax).
 
 As far as I can tell, anyone using ISDN with mainline kernel drivers in
 the past few years uses mISDN, and this is typically used for voice-only
 PBX installations that don't require a public network.
 
 The older stacks support additional features for data networks, but those
 typically make no sense any more if there is no network to connect to.
 
 My proposal for this time is to kill off isdn4linux entirely, as it seems
 to have been unusable for quite a while. This code has been abandoned
 for many years and it does cause problems for treewide maintenance as
 it tends to do everything that we try to stop doing.
 Birger Harzenetter mentioned that is is still using i4l in order to
 make use of the 'divert' feature that is not part of mISDN, but has
 otherwise moved on to mISDN for normal operation, like apparently
 everyone else.
 
 CAPI in turn is not quite as obsolete, but two of the drivers (avm
 and hysdn) don't seem to be used at all, while another one (gigaset)
 will stop being maintained as Paul Bolle is no longer able to
 test it after the network gets shut down in September.
 All three are now moved into drivers/staging to let others speak
 up in case there are remaining users.
 This leaves Bluetooth CMTP as the only remaining user of CAPI, but
 Marcel Holtmann wishes to keep maintaining it.

3e85899637 memcg: make it work on sparse non-0-node systems
We have a single node system with node 0 disabled:
  Scanning NUMA topology in Northbridge 24
  Number of physical nodes 2
  Skipping disabled node 0
  Node 1 MemBase 0000000000000000 Limit 00000000fbff0000
  NODE_DATA(1) allocated [mem 0xfbfda000-0xfbfeffff]

This causes crashes in memcg when system boots:
  BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
  #PF error: [normal kernel read fault]
...
  RIP: 0010:list_lru_add+0x94/0x170

   __fput+0x108/0x230
   task_work_run+0x9f/0xc0
   exit_to_usermode_loop+0xf5/0x100

It is reproducible as far as 4.12.  I did not try older kernels.  You have
to have a new enough systemd, e.g.  241 (the reason is unknown -- was not
investigated).  Cannot be reproduced with systemd 234.

The system crashes because the size of lru array is never updated in
memcg_update_all_list_lrus and the reads are past the zero-sized array,
causing dereferences of random memory.

The root cause are list_lru_memcg_aware checks in the list_lru code.  The
test in list_lru_memcg_aware is broken: it assumes node 0 is always
present, but it is not true on some systems as can be seen above.

So fix this by avoiding checks on node 0.  Remember the memcg-awareness by
a bool flag in struct list_lru.

9852ae3fe5 mm, memcg: consider subtrees in memory.events
memory.stat and other files already consider subtrees in their output, and
we should too in order to not present an inconsistent interface.

The current situation is fairly confusing, because people interacting with
cgroups expect hierarchical behaviour in the vein of memory.stat,
cgroup.events, and other files.  For example, this causes confusion when
debugging reclaim events under low, as currently these always read "0" at
non-leaf memcg nodes, which frequently causes people to misdiagnose breach
behaviour.  The same confusion applies to other counters in this file when
debugging issues.

Aggregation is done at write time instead of at read-time since these
counters aren't hot (unlike memory.stat which is per-page, so it does it
at read time), and it makes sense to bundle this with the file
notifications.

After this patch, events are propagated up the hierarchy:

    [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events
    low 0
    high 0
    max 0
    oom 0
    oom_kill 0
    [root@ktst ~]# systemd-run -p MemoryMax=1 true
    Running as unit: run-r251162a189fb4562b9dabfdc9b0422f5.service
    [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events
    low 0
    high 0
    max 7
    oom 1
    oom_kill 1

As this is a change in behaviour, this can be reverted to the old
behaviour by mounting with the `memory_localevents' flag set.  However, we
use the new behaviour by default as there's a lack of evidence that there
are any current users of memory.events that would find this change
undesirable.

akpm: this is a behaviour change, so Cc:stable.  THis is so that
forthcoming distros which use cgroup v2 are more likely to pick up the
revised behaviour.

b936ca643a bpf: rework memlock-based memory accounting for maps
In order to unify the existing memlock charging code with the
memcg-based memory accounting, which will be added later, let's
rework the current scheme.

Currently the following design is used:
  1) .alloc() callback optionally checks if the allocation will likely
     succeed using bpf_map_precharge_memlock()
  2) .alloc() performs actual allocations
  3) .alloc() callback calculates map cost and sets map.memory.pages
  4) map_create() calls bpf_map_init_memlock() which sets map.memory.user
     and performs actual charging; in case of failure the map is
     destroyed
  <map is in use>
  1) bpf_map_free_deferred() calls bpf_map_release_memlock(), which
     performs uncharge and releases the user
  2) .map_free() callback releases the memory

The scheme can be simplified and made more robust:
  1) .alloc() calculates map cost and calls bpf_map_charge_init()
  2) bpf_map_charge_init() sets map.memory.user and performs actual
    charge
  3) .alloc() performs actual allocations
  <map is in use>
  1) .map_free() callback releases the memory
  2) bpf_map_charge_finish() performs uncharge and releases the user

The new scheme also allows to reuse bpf_map_charge_init()/finish()
functions for memcg-based accounting. Because charges are performed
before actual allocations and uncharges after freeing the memory,
no bogus memory pressure can be created.

In cases when the map structure is not available (e.g. it's not
created yet, or is already destroyed), on-stack bpf_map_memory
structure is used. The charge can be transferred with the
bpf_map_charge_move() function.

5cf1e91456 bpf: cgroup inet skb programs can return 0 to 3
Allows cgroup inet skb programs to return values in the range [0, 3].
The second bit is used to deterine if congestion occurred and higher
level protocol should decrease rate. E.g. TCP would call tcp_enter_cwr()

The bpf_prog must set expected_attach_type to BPF_CGROUP_INET_EGRESS
at load time if it uses the new return values (i.e. 2 or 3).

The expected_attach_type is currently not enforced for
BPF_PROG_TYPE_CGROUP_SKB.  e.g Meaning the current bpf_prog with
expected_attach_type setting to BPF_CGROUP_INET_EGRESS can attach to
BPF_CGROUP_INET_INGRESS.  Blindly enforcing expected_attach_type will
break backward compatibility.

This patch adds a enforce_expected_attach_type bit to only
enforce the expected_attach_type when it uses the new
return value.

1f52f6c0b0 bpf: Create BPF_PROG_CGROUP_INET_EGRESS_RUN_ARRAY
Create new macro BPF_PROG_CGROUP_INET_EGRESS_RUN_ARRAY() to be used by
__cgroup_bpf_run_filter_skb for EGRESS BPF progs so BPF programs can
request cwr for TCP packets.

Current cgroup skb programs can only return 0 or 1 (0 to drop the
packet. This macro changes the behavior so the low order bit
indicates whether the packet should be dropped (0) or not (1)
and the next bit is used for congestion notification (cn).

Hence, new allowed return values of CGROUP EGRESS BPF programs are:
  0: drop packet
  1: keep packet
  2: drop packet and call cwr
  3: keep packet and call cwr

This macro then converts it to one of NET_XMIT values or -EPERM
that has the effect of dropping the packet with no cn.
  0: NET_XMIT_SUCCESS  skb should be transmitted (no cn)
  1: NET_XMIT_DROP     skb should be dropped and cwr called
  2: NET_XMIT_CN       skb should be transmitted and cwr called
  3: -EPERM            skb should be dropped (no cn)

Note that when more than one BPF program is called, the packet is
dropped if at least one of programs requests it be dropped, and
there is cn if at least one program returns cn.

e8d67fa569 net: dsa: sja1105: Don't store frame type in skb->cb
Due to a confusion I thought that eth_type_trans() was called by the
network stack whereas it can actually be called by network drivers to
figure out the skb protocol and next packet_type handlers.

In light of the above, it is not safe to store the frame type from the
DSA tagger's .filter callback (first entry point on RX path), since GRO
is yet to be invoked on the received traffic.  Hence it is very likely
that the skb->cb will actually get overwritten between eth_type_trans()
and the actual DSA packet_type handler.

Of course, what this patch fixes is the actual overwriting of the

0ccc171ea6 net/mlx5: Geneve, Manage Geneve TLV options
Use Geneve TLV Options object to manage the flex parser matching
on the 32-bit options data.

When the first flow with a certain class/type values is requested to
be offloaded, create a FW object with FW command (Geneve TLV Options
general object) and start counting the number of flows using this object.

During this time, any request with a different class/type values will
fail to be offloaded.
Once the refcount reaches 0, destroy the TLV options general object,
and can now offload a flow with any class/type parameters.

Geneve TLV Options object is added to core device.
It is currently used to manage Geneve TLV options general
object allocation in FW and its reference counting only.
In the future it will also be used for managing geneve ports
by registering callbacks for ndo_udp_tunnel_add/del.

8693115af4 {IB,net}/mlx5: Constify rep ops functions pointers
Currently for every representor type and for every single vport,
representer function pointers copy is stored even though they don't
change from one to other vport.

Additionally priv data entry for the rep is not passed during
registration, but its copied. It is used (set and cleared) by the user
of the reps.

As we want to scale vports, to simplify and also to split constants
from data,

1. Rename mlx5_eswitch_rep_if to mlx5_eswitch_rep_ops as to match _ops
prefix with other standard netdev, ibdev ops.
2. Constify the IB and Ethernet rep ops structure.
3. Instead of storing copy of all rep function pointers, store copy
per eswitch rep type.
4. Split data and function pointers to mlx5_eswitch_rep_ops and
mlx5_eswitch_rep_data.

CSS_TASK_ITER_PROCS currently iterates live group leaders; however,
this means that a process with dying leader and live threads will be
skipped.  IOW, cgroup.procs might be empty while cgroup.threads isn't,
which is confusing to say the least.

Fix it by making cset track dying tasks and include dying leaders with
live threads in PROCS iteration.

b636fd38dc cgroup: Implement css_task_iter_skip()
When a task is moved out of a cset, task iterators pointing to the
task are advanced using the normal css_task_iter_advance() call.  This
is fine but we'll be tracking dying tasks on csets and thus moving
tasks from cset->tasks to (to be added) cset->dying_tasks.  When we
remove a task from cset->tasks, if we advance the iterators, they may
move over to the next cset before we had the chance to add the task
back on the dying list, which can allow the task to escape iteration.

This patch separates out skipping from advancing.  Skipping only moves
the affected iterators to the next pointer rather than fully advancing
it and the following advancing will recognize that the cursor has
already been moved forward and do the rest of advancing.  This ensures
that when a task moves from one list to another in its cset, as long
as it moves in the right direction, it's always visible to iteration.

This doesn't cause any visible behavior changes.

With all isdn4linux hardware drivers gone, this is only a wrapper around
CAPI to support old user space. However, from looking at the mailing
list, it seems that the last time anyone asked about it was in 2014,

suggested as a replacement.

The largest public ISDN network (Deutsche Telekom) was supposed to be
shut down 2018, which must have drastically reduced the number of legacy
installations.

When we last discussed removing i4l in 2016, Karsten Keil suggested
revisiting this in 2018. I guess this is overdue.
