9932fb7250 octeontx2-af: Manage new blocks in 98xx
AF manages the tasks of allocating, freeing
LFs from RVU blocks to PF and VFs. With new
NIX1 and CPT1 blocks in 98xx, this patch
adds support for handling new blocks too.

cdd41e8785 octeontx2-af: Update get/set resource count functions
Since multiple blocks of same type are present in
98xx, modify functions which get resource count and
which update resource count to work with individual
block address instead of block type.

624251b4b5 net: ipa: avoid a bogus warning
The previous commit added support for IPA having up to six source
and destination resources.  But currently nothing uses more than
four.  (Five of each are used in a newer version of the hardware.)

I find that in one of my build environments the compiler complains
about newly-added code in two spots.  Inspection shows that the
warnings have no merit, but this compiler does not recognize that.

    ipa_main.c:457:39: warning: array index 5 is past the end of the
        array (which contains 4 elements) [-Warray-bounds]
    (and the same warning at line 483)

We can make this warning go away by changing the number of elements
in the source and destination resource limit arrays--now rather than
waiting until we need it to support the newer hardware.  This change
was coming soon anyway; make it now to get rid of the warning.

Hangbin Liu says:

====================
IPv6: reply ICMP error if fragment doesn't contain all headers

When our Engineer run latest IPv6 Core Conformance test, test v6LC.1.3.6:
First Fragment Doesn’t Contain All Headers[1] failed. The test purpose is to
verify that the node (Linux for example) should properly process IPv6 packets
that don’t include all the headers through the Upper-Layer header.

Based on RFC 8200, Section 4.5 Fragment Header

  -  If the first fragment does not include all headers through an
     Upper-Layer header, then that fragment should be discarded and
     an ICMP Parameter Problem, Code 3, message should be sent to
     the source of the fragment, with the Pointer field set to zero.

The first patch add a definition for ICMPv6 Parameter Problem, code 3.
The second patch add a check for the 1st fragment packet to make sure
Upper-Layer header exist.

2efdaaaf88 IPv6: reply ICMP error if the first fragment don't include all headers
Based on RFC 8200, Section 4.5 Fragment Header:

  -  If the first fragment does not include all headers through an
     Upper-Layer header, then that fragment should be discarded and
     an ICMP Parameter Problem, Code 3, message should be sent to
     the source of the fragment, with the Pointer field set to zero.

Checking each packet header in IPv6 fast path will have performance impact,
so I put the checking in ipv6_frag_rcv().

As the packet may be any kind of L4 protocol, I only checked some common
protocols' header length and handle others by (offset + 1) > skb->len.
Also use !(frag_off & htons(IP6_OFFSET)) to catch atomic fragments
(fragmented packet with only one fragment).

When send ICMP error message, if the 1st truncated fragment is ICMP message,
icmp6_send() will break as is_ineligible() return true. So I added a check
in is_ineligible() to let fragment packet with nexthdr ICMP but no ICMP header
return false.

====================
in_interrupt() cleanup, part 2

in the discussion about preempt count consistency across kernel configurations:

  https://lore.kernel.org/r/20200914204209.256266093@linutronix.de/

Linus clearly requested that code in drivers and libraries which changes
behaviour based on execution context should either be split up so that
e.g. task context invocations and BH invocations have different interfaces
or if that's not possible the context information has to be provided by the
caller which knows in which context it is executing.

This includes conditional locking, allocation mode (GFP_*) decisions and
avoidance of code paths which might sleep.

In the long run, usage of 'preemptible, in_*irq etc.' should be banned from
driver code completely.

This is part two addressing remaining drivers except for orinoco-usb.

beca92820d net: tlan: Replace in_irq() usage
The driver uses in_irq() to determine if the tlan_priv::lock has to be
acquired in tlan_mii_read_reg() and tlan_mii_write_reg().

The interrupt handler acquires the lock outside of these functions so the
in_irq() check is meant to prevent a lock recursion deadlock. But this
check is incorrect when interrupt force threading is enabled because then
the handler runs in thread context and in_irq() correctly returns false.

The usage of in_*() in drivers is phased out and Linus clearly requested
that code which changes behaviour depending on context should either be
seperated or the context be conveyed in an argument passed by the caller,
which usually knows the context.

tlan_set_timer() has this conditional as well, but this function is only
invoked from task context or the timer callback itself. So it always has to
lock and the check can be removed.

tlan_mii_read_reg(), tlan_mii_write_reg() and tlan_phy_print() are invoked
from interrupt and other contexts.

Split out the actual function body into helper variants which are called
from interrupt context and make the original functions wrappers which
acquire tlan_priv::lock unconditionally.

nv_update_stats() triggers a WARN_ON() when invoked from hard interrupt
context because the locks in use are not hard interrupt safe. It also has
an assert_spin_locked() which was the lock check before the lockdep era.

Lockdep has way broader locking correctness checks and covers both issues,
so replace the warning and the lock assert with lockdep_assert_held().

5ce7f3f46f net: neterion: s2io: Replace in_interrupt() for context detection
wait_for_cmd_complete() uses in_interrupt() to detect whether it is safe to
sleep or not.

The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be seperated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

in_interrupt() also is only partially correct because it fails to chose the
correct code path when just preemption or interrupts are disabled.

Add an argument 'may_block' to both functions and adjust the callers to
pass the context information.

The following call chains which end up invoking wait_for_cmd_complete()
were analyzed to be safe to sleep:

 s2io_card_up()
   s2io_set_multicast()

 init_nic()
   init_tti()

 s2io_close()
   do_s2io_delete_unicast_mc()
     do_s2io_add_mac()

   do_s2io_restore_unicast_mc()
     do_s2io_add_mc()
       do_s2io_add_mac()

 s2io_open()
   do_s2io_prog_unicast()
     do_s2io_add_mac()

The following call chains which end up invoking wait_for_cmd_complete()
were analyzed to be safe to sleep:

 __dev_set_rx_mode()
    s2io_set_multicast()

 s2io_txpic_intr_handle()
   s2io_link()
     init_tti()

Add a may_sleep argument to wait_for_cmd_complete(), s2io_set_multicast()
and init_tti() and hand the context information in from the call sites.

correct. Turns out, static key magic doesn't work in '__init' section
(and it is unclear when things changed) but setup_vmcs_config() is called
only once per CPU so we don't really need it to. Switch to checking
'enlightened_vmcs' instead, it is supposed to be in sync with
'enable_evmcs'.

Opportunistically make evmcs_sanitize_exec_ctrls '__init' and drop unneeded
extra newline from it.

97a71a5455 KVM: selftests: test behavior of unmapped L2 APIC-access address
Add a regression test for commit 671ddc700f ("KVM: nVMX: Don't leak
L1 MMIO regions to L2").

First, check to see that an L2 guest can be launched with a valid
APIC-access address that is backed by a page of L1 physical memory.

Next, set the APIC-access address to a (valid) L1 physical address
that is not backed by memory. KVM can't handle this situation, so
resuming L2 should result in a KVM exit for internal error
(emulation).

7d10e62c2f netfilter: ipset: Update byte and packet counters regardless of whether they match
In ip_set_match_extensions(), for sets with counters, we take care of
updating counters themselves by calling ip_set_update_counter(), and of
checking if the given comparison and values match, by calling
ip_set_match_counter() if needed.

However, if a given comparison on counters doesn't match the configured
values, that doesn't mean the set entry itself isn't matching.

This fix restores the behaviour we had before commit 4750005a85
("netfilter: ipset: Fix "don't update counters" mode when counters used
at the matching"), without reintroducing the issue fixed there: back
then, mtype_data_match() first updated counters in any case, and then
took care of matching on counters.

Now, if the IPSET_FLAG_SKIP_COUNTER_UPDATE flag is set,
ip_set_update_counter() will anyway skip counter updates if desired.

The issue observed is illustrated by this reproducer:

  ipset create c hash:ip counters
  ipset add c 192.0.2.1
  iptables -I INPUT -m set --match-set c src --bytes-gt 800 -j DROP

if we now send packets from 192.0.2.1, bytes and packets counters
for the entry as shown by 'ipset list' are always zero, and, no
matter how many bytes we send, the rule will never match, because
counters themselves are not updated.

e5d1f896fd net: mscc: ocelot: support L2 multicast entries
There is one main difference in mscc_ocelot between IP multicast and L2
multicast. With IP multicast, destination ports are encoded into the
upper bytes of the multicast MAC address. Example: to deliver the
address 01:00:5E:11:22:33 to ports 3, 8, and 9, one would need to
program the address of 00:03:08:11:22:33 into hardware. Whereas for L2
multicast, the MAC table entry points to a Port Group ID (PGID), and
that PGID contains the port mask that the packet will be forwarded to.
As to why it is this way, no clue. My guess is that not all port
combinations can be supported simultaneously with the limited number of
PGIDs, and this was somehow an issue for IP multicast but not for L2
multicast. Anyway.

Prior to this change, the raw L2 multicast code was bogus, due to the
fact that there wasn't really any way to test it using the bridge code.
There were 2 issues:
- A multicast PGID was allocated for each MDB entry, but it wasn't in
  fact programmed to hardware. It was dummy.
- In fact we don't want to reserve a multicast PGID for every single MDB
  entry. That would be odd because we can only have ~60 PGIDs, but
  thousands of MDB entries. So instead, we want to reserve a multicast
  PGID for every single port combination for multicast traffic. And
  since we can have 2 (or more) MDB entries delivered to the same port
  group (and therefore PGID), we need to reference-count the PGIDs.

When creating a new multicast port group, there is implicit conversion
between the __u8 state member of struct br_mdb_entry and the unsigned
char flags member of struct net_bridge_port_group. This implicit
conversion relies on the fact that MDB_PERMANENT is equal to
MDB_PG_FLAGS_PERMANENT.
