nf_defrag modules for ipv4 and ipv6 export an empty stub function.
Any module that needs the defragmentation hooks registered simply 'calls'
this empty function to create a phony module dependency -- modprobe will
then load the defrag module too.
This extends netfilter ipv4/ipv6 defragmentation modules to delay the hook
registration until the functionality is requested within a network namespace
instead of module load time for all namespaces.
Hooks are only un-registered on module unload or when a namespace that used
such defrag functionality exits.
We have to use struct net for this as the register hooks can be called
before netns initialization here from the ipv4/ipv6 conntrack module
init path.
There is no unregister functionality support, defrag will always be
active once it was requested inside a net namespace.
The reason is that defrag has impact on nft and iptables rulesets
(without defrag we might see framents).

PCIe controllers in X-Gene SoCs are not ECAM compliant: software needs to
configure additional controller's register to address device at
bus:dev:function.
Add a quirk to discover controller MMIO register space and configure
controller registers to select and address the target secondary device.
The quirk will only be applied for X-Gene PCIe MCFG table with
OEM revison 1, 2, 3 or 4 (PCIe controller v1 and v2 on X-Gene SoCs).

ThunderX pass1.x requires to emulate the EA headers for on-chip devices
hence it has to use custom pci_thunder_ecam_ops for accessing PCI config
space (pci-thunder-ecam.c). Add new entries to MCFG quirk array where it
can be applied while probing ACPI based PCI host controller.
ThunderX pass1.x is using the same way for accessing off-chip devices
(so-called PEM) as silicon pass-2.x so we need to add PEM quirk entries
too.
Quirk is considered for ThunderX silicon pass1.x only which is identified
via MCFG revision 2.
ThunderX pass 1.x requires the following accessors:
NUMA node 0 PCI segments 0- 3: pci_thunder_ecam_ops (MCFG quirk)
NUMA node 0 PCI segments 4- 9: thunder_pem_ecam_ops (MCFG quirk)
NUMA node 1 PCI segments 10-13: pci_thunder_ecam_ops (MCFG quirk)
NUMA node 1 PCI segments 14-19: thunder_pem_ecam_ops (MCFG quirk)

ThunderX PCIe controller to off-chip devices (so-called PEM) is not fully
compliant with ECAM standard. It uses non-standard configuration space
accessors (see thunder_pem_ecam_ops) and custom configuration space
granulation (see bus_shift = 24). In order to access configuration space
and probe PEM as ACPI-based PCI host controller we need to add MCFG quirk
infrastructure. This involves:
1. A new thunder_pem_acpi_init() init function to locate PEM-specific
register ranges using ACPI.
2. Export PEM thunder_pem_ecam_ops structure so it is visible to MCFG quirk
code.
3. New quirk entries for each PEM segment. Each contains platform IDs,
mentioned thunder_pem_ecam_ops and CFG resources.
Quirk is considered for ThunderX silicon pass2.x only which is identified
via MCFG revision 1.
ThunderX pass 2.x requires the following accessors:
NUMA Node 0 PCI segments 0- 3: pci_generic_ecam_ops (ECAM-compliant)
NUMA Node 0 PCI segments 4- 9: thunder_pem_ecam_ops (MCFG quirk)
NUMA Node 1 PCI segments 10-13: pci_generic_ecam_ops (ECAM-compliant)
NUMA Node 1 PCI segments 14-19: thunder_pem_ecam_ops (MCFG quirk)

The PCIe controller in Hip05/Hip06/Hip07 SoCs is not completely
ECAM-compliant. It is non-ECAM only for the RC bus config space; for any
other bus underneath the root bus it does support ECAM access.
Add specific quirks for PCI config space accessors. This involves:
1. New initialization call hisi_pcie_init() to obtain RC base
addresses from PNP0C02 at the root of the ACPI namespace (under \_SB).
2. New entry in common quirk array.

pci_mcfg_lookup() is the external interface to the generic MCFG code.
Previously it merely looked up the ECAM base address for a given domain and
bus range. We want a way to add MCFG quirks, some of which may require
special config accessors and adjustments to the ECAM address range.
Extend pci_mcfg_lookup() so it can return a pointer to a pci_ecam_ops
structure and a struct resource for the ECAM address space. For now, it
always returns &pci_generic_ecam_ops (the standard accessor) and the
resource described by the MCFG.
No functional changes intended.

Pull networking fixes from David Miller:
1) When dcbnl_cee_fill() fails to be able to push a new netlink
attribute, it return 0 instead of an error code. From Pan Bian.
2) Two suffix handling fixes to FIB trie code, from Alexander Duyck.
3) bnxt_hwrm_stat_ctx_alloc() goes through all the trouble of setting
and maintaining a return code 'rc' but fails to actually return it.
Also from Pan Bian.
4) ping socket ICMP handler needs to validate ICMP header length, from
Kees Cook.
5) caif_sktinit_module() has this interesting logic:
int err = sock_register(...);
if (!err)
return err;
return 0;
Just return sock_register()'s return value directly which is the
only possible correct thing to do.
6) Two bnx2x driver fixes from Yuval Mintz, return a reasonable
estimate from get_ringparam() ethtool op when interface is down and
avoid trying to use UDP port based tunneling on 577xx chips.
7) Fix ep93xx_eth crash on module unload from Florian Fainelli.
8) Missing uapi exports, from Stephen Hemminger.
9) Don't schedule work from sk_destruct(), because the socket will be
freed upon return from that function. From Herbert Xu.
10) Buggy drivers, of which we know there is at least one, can send a
huge packet into the TCP stack but forget to set the gso_size in the
SKB, which causes all kinds of problems.
Correct this when it happens, and emit a one-time warning with the
device name included so that it can be diagnosed more easily.
From Marcelo Ricardo Leitner.
11) virtio-net does DMA off the stack causes hiccups with VMAP_STACK,
fix from Andy Lutomirski.
12) Fix fec driver compilation with CONFIG_M5272, from Nikita
Yushchenko.
13) mlx5 fixes from Kamal Heib, Saeed Mahameed, and Mohamad Haj Yahia.

etc)

The introduction of acpi_dma_configure() allows to configure DMA
and related IOMMU for any device that is DMA capable. To achieve
that goal it ensures DMA masks are set-up to sane default values
before proceeding with IOMMU and DMA ops configuration.
On x86/ia64 systems, through acpi_bind_one(), acpi_dma_configure() is
called for every device that has an ACPI companion, in that every device
is considered DMA capable on x86/ia64 systems (ie acpi_get_dma_attr() API),
which has the side effect of initializing dma masks also for
pseudo-devices (eg CPUs and memory nodes) and potentially for devices
whose dma masks were not set-up before the acpi_dma_configure() API was
introduced, which may have noxious side effects.
Therefore, in preparation for IORT firmware specific DMA masks set-up,
wrap the default DMA masks set-up in acpi_dma_configure() inside an IORT
specific wrapper that reverts to a NOP on x86/ia64 systems, restoring the
default expected behaviour on x86/ia64 systems and keeping DMA default
masks set-up on IORT based (ie ARM) arch configurations.

When loading a BPF program via bpf(2), calculate the digest over
the program's instruction stream and store it in struct bpf_prog's
digest member. This is done at a point in time before any instructions
are rewritten by the verifier. Any unstable map file descriptor
number part of the imm field will be zeroed for the hash.
fdinfo example output for progs:
# cat /proc/1590/fdinfo/5
pos: 0
flags: 02000002
mnt_id: 11
prog_type: 1
prog_jited: 1
prog_digest: b27e8b06da22707513aa97363dfb11c7c3675d28
memlock: 4096
When programs are pinned and retrieved by an ELF loader, the loader
can check the program's digest through fdinfo and compare it against
one that was generated over the ELF file's program section to see
if the program needs to be reloaded. Furthermore, this can also be
exposed through other means such as netlink in case of a tc cls/act
dump (or xdp in future), but also through tracepoints or other
facilities to identify the program. Other than that, the digest can
also serve as a base name for the work in progress kallsyms support
of programs. The digest doesn't depend/select the crypto layer, since
we need to keep dependencies to a minimum. iproute2 will get support
for this facility.

1) Old code was hard to maintain, due to complex lock chains.
(We probably will be able to remove some kfree_rcu() in callers)
2) Using a single timer to update all estimators does not scale.
3) Code was buggy on 32bit kernel (WRITE_ONCE() on 64bit quantity
is not supposed to work well)
In this rewrite :
- I removed the RB tree that had to be scanned in
gen_estimator_active(). qdisc dumps should be much faster.
- Each estimator has its own timer.
- Estimations are maintained in net_rate_estimator structure,
instead of dirtying the qdisc. Minor, but part of the simplification.
- Reading the estimator uses RCU and a seqcount to provide proper
support for 32bit kernels.
- We reduce memory need when estimators are not used, since
we store a pointer, instead of the bytes/packets counters.
- xt_rateest_mt() no longer has to grab a spinlock.
(In the future, xt_rateest_tg() could be switched to per cpu counters)
