pull-request: bpf-next 2019-01-29
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Teach verifier dead code removal, this also allows for optimizing /
removing conditional branches around dead code and to shrink the
resulting image. Code store constrained architectures like nfp would
have hard time doing this at JIT level, from Jakub.
2) Add JMP32 instructions to BPF ISA in order to allow for optimizing
code generation for 32-bit sub-registers. Evaluation shows that this
can result in code reduction of ~5-20% compared to 64 bit-only code
generation. Also add implementation for most JITs, from Jiong.
3) Add support for __int128 types in BTF which is also needed for
vmlinux's BTF conversion to work, from Yonghong.
4) Add a new command to bpftool in order to dump a list of BPF-related
parameters from the system or for a specific network device e.g. in
terms of available prog/map types or helper functions, from Quentin.
5) Add AF_XDP sock_diag interface for querying sockets from user
space which provides information about the RX/TX/fill/completion
rings, umem, memory usage etc, from Björn.
6) Add skb context access for skb_shared_info->gso_segs field, from Eric.
7) Add support for testing flow dissector BPF programs by extending
existing BPF_PROG_TEST_RUN infrastructure, from Stanislav.
8) Split BPF kselftest's test_verifier into various subgroups of tests
in order better deal with merge conflicts in this area, from Jakub.
9) Add support for queue/stack manipulations in bpftool, from Stanislav.
10) Document BTF, from Yonghong.
11) Dump supported ELF section names in libbpf on program load
failure, from Taeung.
12) Silence a false positive compiler warning in verifier's BTF
handling, from Peter.
13) Fix help string in bpftool's feature probing, from Prashant.
14) Remove duplicate includes in BPF kselftests, from Yue.

Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next tree:
1) Introduce a hashtable to speed up object lookups, from Florian Westphal.
2) Make direct calls to built-in extension, also from Florian.
3) Call helper before confirming the conntrack as it used to be originally,
from Florian.
4) Call request_module() to autoload br_netfilter when physdev is used
to relax the dependency, also from Florian.
5) Allow to insert rules at a given position ID that is internal to the
batch, from Phil Sutter.
6) Several patches to replace conntrack indirections by direct calls,
and to reduce modularization, from Florian. This also includes
several follow up patches to deal with minor fallout from this
rework.
7) Use RCU from conntrack gre helper, from Florian.
8) GRE conntrack module becomes built-in into nf_conntrack, from Florian.
9) Replace nf_ct_invert_tuplepr() by calls to nf_ct_invert_tuple(),
from Florian.
10) Unify sysctl handling at the core of nf_conntrack, from Florian.
11) Provide modparam to register conntrack hooks.
12) Allow to match on the interface kind string, from wenxu.
13) Remove several exported symbols, not required anymore now after
a bit of de-modulatization work has been done, from Florian.
14) Remove built-in map support in the hash extension, this can be
done with the existing userspace infrastructure, from laura.
15) Remove indirection to calculate checksums in IPVS, from Matteo Croce.
16) Use call wrappers for indirection in IPVS, also from Matteo.
17) Remove superfluous __percpu parameter in nft_counter, patch from
Luc Van Oostenryck.

Pull libnvdimm fixes from Dan Williams:
"A fix for namespace label support for non-Intel NVDIMMs that implement
the ACPI standard label method.
This has apparently never worked and could wait for v5.1. However it
has enough visibility with hardware vendors [1] and distro bug
trackers [2], and low enough risk that I decided it should go in for
-rc4. The other fixups target the new, for v5.0, nvdimm security
functionality. The larger init path fixup closes a memory leak and a
potential userspace lockup due to missed notifications.

Let offload JITs know when instructions are replaced and optimized

are best effort, if JIT returns an error from any callback verifier
will stop notifying it as state may now be out of sync, but the

This patch is to add debugfs support for ptp_qoriq. Current debugfs
supports to control fiper1/fiper2 loopback mode. If the loopback mode
is enabled, the fiper1/fiper2 pulse is looped back into trigger1/
trigger2 input. This is very useful for validating hardware and driver
without external hardware. Below is an example to enable fiper1 loopback.

The external trigger stamp FIFO was introduced as a new feature
for QorIQ 1588 timer IP block. This patch is to support it by
adding a new dts property "fsl,extts-fifo". Any QorIQ 1588 timer
supporting this feature is required to add this property in its
dts node.
In addition, the FIFO should be cleaned up before enabling external
trigger interrupts. Otherwise, there will be interrupts immediately
just after enabling external trigger interrupts.

When multiple multicast routers are present in a broadcast domain then
only one of them will be detectable via IGMP/MLD query snooping. The
multicast router with the lowest IP address will become the selected and
active querier while all other multicast routers will then refrain from
sending queries.
To detect such rather silent multicast routers, too, RFC4286
("Multicast Router Discovery") provides a standardized protocol to
detect multicast routers for multicast snooping switches.
This patch implements the necessary MRD Advertisement message parsing
and after successful processing adds such routers to the internal
multicast router list.

This patch refactors ip_mc_check_igmp(), ipv6_mc_check_mld() and
their callers (more precisely, the Linux bridge) to not rely on
the skb_trimmed parameter anymore.
An skb with its tail trimmed to the IP packet length was initially
introduced for the following three reasons:
1) To be able to verify the ICMPv6 checksum.
2) To be able to distinguish the version of an IGMP or MLD query.
They are distinguishable only by their size.
3) To avoid parsing data for an IGMPv3 or MLDv2 report that is
beyond the IP packet but still within the skb.
The first case still uses a cloned and potentially trimmed skb to
verfiy. However, there is no need to propagate it to the caller.
For the second and third case explicit IP packet length checks were
added.
This hopefully makes ip_mc_check_igmp() and ipv6_mc_check_mld() easier
to read and verfiy, as well as easier to use.

sync_inodes_sb() can race against cgwb (cgroup writeback) membership
switches and fail to writeback some inodes. For example, if an inode
switches to another wb while sync_inodes_sb() is in progress, the new
wb might not be visible to bdi_split_work_to_wbs() at all or the inode
might jump from a wb which hasn't issued writebacks yet to one which
already has.
This patch adds backing_dev_info->wb_switch_rwsem to synchronize cgwb
switch path against sync_inodes_sb() so that sync_inodes_sb() is
guaranteed to see all the target wbs and inodes can't jump wbs to
escape syncing.

There have been many people complaining about the inconsistent
behaviors of IPv4 and IPv6 devconf when creating new network
namespaces. Currently, for IPv4, we inherit all current settings
from init_net, but for IPv6 we reset all setting to default.
This patch introduces a new /proc file
/proc/sys/net/core/devconf_inherit_init_net to control the
behavior of whether to inhert sysctl current settings from init_net.
This file itself is only available in init_net.
As demonstrated below:
Initial setup in init_net:
# cat /proc/sys/net/ipv4/conf/all/rp_filter
2
# cat /proc/sys/net/ipv6/conf/all/accept_dad
1
Default value 0 (current behavior):
# ip netns del test
# ip netns add test
# ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter
2
# ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad
0
Set to 1 (inherit from init_net):
# echo 1 > /proc/sys/net/core/devconf_inherit_init_net
# ip netns del test
# ip netns add test
# ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter
2
# ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad
1
Set to 2 (reset to default):
# echo 2 > /proc/sys/net/core/devconf_inherit_init_net
# ip netns del test
# ip netns add test
# ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter
0
# ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad
0
Set to a value out of range (invalid):
# echo 3 > /proc/sys/net/core/devconf_inherit_init_net
-bash: echo: write error: Invalid argument
# echo -1 > /proc/sys/net/core/devconf_inherit_init_net

The following warning:
ACPI0012:00: security event setup failed: -19
...is meant to capture exceptional failures of sysfs_get_dirent(),
however it will also fail in the common case when security support is
disabled. A few issues:
1/ A dev_warn() report for a common case is too chatty
2/ The setup of this notifier is generic, no need for it to be driven
from the nfit driver, it can exist completely in the core.
3/ If it fails for any reason besides security support being disabled,
that's fatal and should abort DIMM activation. Userspace may hang if
it never gets overwrite notifications.
4/ The dirent needs to be released.
Move the call to the core 'dimm' driver, make it conditional on security
support being active, make it fatal for the exceptional case, add the
missing sysfs_put() at device disable time.

Pull MIPS fixes from Paul Burton:
- Fix IPI handling for Lantiq SoCs, which was broken by changes made
back in v4.12.
- Enable OF/DT serial support in ath79_defconfig to give us working
serial by default.
- Fix 64b builds for the Jazz platform.
- Set up a struct device for the BCM47xx SoC to allow BCM47xx drivers
to perform DMA again following the major DMA mapping changes made in
v4.19.
- Disable MSI on Cavium Octeon systems when the pcie_disable command
line parameter introduced in v3.3 is used, in order to avoid
inadvetently accessing PCIe controller registers despite the command
line.
- Fix a build failure for Cavium Octeon kernels with kexec enabled,
introduced in v4.20.
- Fix a regression in the behaviour of semctl/shmctl/msgctl IPC
syscalls for kernels including n32 support but not o32 support caused
by some cleanup in v3.19.

Pull libnvdimm fixes from Dan Williams:
"A crash fix, a build warning fix, a miscellaneous small cleanups.
In case anyone is looking for them, there was a regression caught by
testing that caused two patches to be dropped from this update. Those
patches have been reworked and will soak for another week / re-target
5.0-rc4.
- Fix driver initialization crash due to the inability to report an
'error' state for a DIMM's security capability.
- Build warning fix for little-endian ARM64 builds
- Fix a potential race between the EDAC driver's usage of the NFIT
SMBIOS id for a DIMM and the driver shutdown path.
- A small collection of one-line benign cleanups for duplicate
variable assignments, a duplicate header include and a mis-typed
function argument"

Dumps can read state of the NETLINK_F_STRICT_CHK flag from
a field in the callback structure. For non-dump GET requests
we need a way to access the state of that flag from a socket.

Since phy driver features became a link_mode bitmap, phy drivers that
don't have a list of features configured will cause the kernel to crash
when probed.
Prevent the phy driver from registering if the features field is missing.

We can use gre. Lock is only needed when a new expectation is added.
In case a single spinlock proves to be problematic we can either add one
per netns or use an array of locks combined with net_hash_mix() or similar
to pick the 'correct' one.
But given this is only needed for an expectation rather than per packet
a single one should be ok.

Drivers may not be able to support certain FDB entries, and an error
code is insufficient to give clear hints as to the reasons of rejection.
In order to make it possible to communicate the rejection reason, extend
ndo_fdb_add() with an extack argument. Adapt the existing
implementations of ndo_fdb_add() to take the parameter (and ignore it).
Pass the extack parameter when invoking ndo_fdb_add() from rtnl_fdb_add().

We are already checking in phy_detach() that the PHY driver is of

layer as well for 1000BaseT SFP modules, so expose helper functions to
