The score architecture used a number of old system calls for compatibility
with a traditional libc port, all architectures that got added later
skip these. With score out of the way, we can finally clean up the
syscall list to no longer provide these.

Unlike system call numbers the assignment of si_codes has never had a
reason to be made per architecture. Some architectures have had unique
conditions to report and reporting those conditions needed new si_codes.
Nothing has ever needed si_codes to have different values on different
architectures. The si_code space is vast so even with defining all
si_codes on all architectures there is no danger in running out of
si_code values.
The history of the si_codes BUS_MCEERR_AR, BUS_MCEER_AO, SEGV_BNDERR,
and SEGV_PKUERR show that a need of one architecture frequently becomes
a need of another architecture which makes sharing si_codes between
architectures a positive benefit and something to be encouraged.
Where there are no conflicts with the historical ia64 arch specific
si_codes and any other si_codes make them generic si_codes. We might
need them on another architecture someday.
This leaves only the good example of arch generic si_codes in the kernel
for future architectures and architecture enhancments to follow.
Without bad examples to follow it should be easy to avoid the mistakes
of the past.

The frv, tile and blackfin architectures are being removed, so
we can clean up this header by removing all the special cases
except those for ia64.
The SEGV_BNDERR and BUS_MCEERR_AR si_code macros are now
defined unconditionally on all remaining architectures.

The BTF (BPF Type Format) verifier needs to reuse the current
BPF verifier log. Hence, it requires the following changes:
(1) Expose log_write() in verifier.c for other users.
Its name is renamed to bpf_verifier_vlog().
(2) The BTF verifier also needs to check
'log->level && log->ubuf && !bpf_verifier_log_full(log);'
independently outside of the current log_write(). It is
because the BTF verifier will do one-check before
making multiple calls to btf_verifier_vlog to log
the details of a type.
Hence, this check is also re-factored to a new function
bpf_verifier_log_needed(). Since it is re-factored,
we can check it before va_start() in the current
bpf_verifier_log_write() and verbose().

The syscall entry points to the kernel defined by SYSCALL_DEFINEx()
and COMPAT_SYSCALL_DEFINEx() should only be called from userspace
through kernel entry points, but not from the kernel itself. This
will allow cleanups and optimizations to the entry paths *and* to
the parts of the kernel code which currently need to pretend to be
userspace in order to make use of syscalls.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Don't pick fixed hash implementation for NFT_SET_EVAL sets, otherwise
userspace hits EOPNOTSUPP with valid rules using the meter statement,
from Florian Westphal.
2) If you send a batch that flushes the existing ruleset (that contains
a NAT chain) and the new ruleset definition comes with a new NAT
chain, don't bogusly hit EBUSY. Also from Florian.
3) Missing netlink policy attribute validation, from Florian.
4) Detach conntrack template from skbuff if IP_NODEFRAG is set on,
from Paolo Abeni.
5) Cache device names in flowtable object, otherwise we may end up
walking over devices going aways given no rtnl_lock is held.
6) Fix incorrect net_device ingress with ingress hooks.
7) Fix crash when trying to read more data than available in UDP

mlx-platform does not provide a bus number to i2c-mlxcpld, assuming it
is always one. On some x86 systems, other i2c drivers may probe before
i2c-mlxcpld, causing bus one to be busy.
Make mlx-platform determine which adapter number is free prior to
activating i2c-mlxpld, adjusting the mux base numbers accordingly.
Update the mlxreg-hotplug pdata similarly.
This adds an explicit mlx-platform build dependency on I2C, update the
Kconfig accordingly. Add the missing REGMAP dependency while we're at

mlx-platform activates i2c-mux-reg, which creates buses needed by
mlxreg-hotplug. If the mlxreg-hotplug probe runs before the i2c-mux-reg
probe completes, it may attempt to connect a device to an adapter number
that has not been created yet, and fail.
Make mlx-platform driver record the highest bus number in mlxreg-hotplug
platform data and defer mlxreg-hotplug probe until all the buses are
created.

OSS PCM stream management isn't modal but it allows ioctls issued at
any time for changing the parameters. In the previous hardening
patch ("ALSA: pcm: Avoid potential races between OSS ioctls and
read/write"), we covered these races and prevent the corruption by
protecting the concurrent accesses via params_lock mutex. However,
this means that some ioctls that try to change the stream parameter
(e.g. channels or format) would be blocked until the read/write
finishes, and it may take really long.
Basically changing the parameter while reading/writing is an invalid
operation, hence it's even more user-friendly from the API POV if it
returns -EBUSY in such a situation.
This patch adds such checks in the relevant ioctls with the addition
of read/write access refcount.

We add a 128-bit node identity, as an alternative to the currently used
32-bit node address.
For the sake of compatibility and to minimize message header changes
we retain the existing 32-bit address field. When not set explicitly by
the user, this field will be filled with a hash value generated from the
much longer node identity, and be used as a shorthand value for the
latter.
We permit either the address or the identity to be set by configuration,
but not both, so when the address value is set by a legacy user the
corresponding 128-bit node identity is generated based on the that value.

Currently CM request for RoCE follows following flow.
rdma_create_id()
rdma_resolve_addr()
rdma_resolve_route()
For RC QPs:
rdma_connect()
->cma_connect_ib()
->ib_send_cm_req()
->cm_init_av_by_path()
->ib_init_ah_attr_from_path()
For UD QPs:
rdma_connect()
->cma_resolve_ib_udp()
->ib_send_cm_sidr_req()
->cm_init_av_by_path()
->ib_init_ah_attr_from_path()
In both the flows, route is already resolved before sending CM requests.
Therefore, code is refactored to avoid resolving route second time in
ib_cm layer.
ib_init_ah_attr_from_path() is extended to resolve route when it is not
yet resolved for RoCE link layer. This is achieved by caller setting
route_resolved field in path record whenever it has route already
resolved.

Add rx path for tls software implementation.
recvmsg, splice_read, and poll implemented.
An additional sockopt TLS_RX is added, with the same interface as
TLS_TX. Either TLX_RX or TLX_TX may be provided separately, or
together (with two different setsockopt calls with appropriate keys).
Control messages are passed via CMSG in a similar way to transmit.
If no cmsg buffer is passed, then only application data records
will be passed to userspace, and EIO is returned for other types of
alerts.
EBADMSG is passed for decryption errors, and EMSGSIZE is passed for
framing too big, and EBADMSG for framing too small (matching openssl
semantics). EINVAL is returned for TLS versions that do not match the
original setsockopt call. All are unrecoverable.
strparser is used to parse TLS framing. Decryption is done directly
in to userspace buffers if they are large enough to support it, otherwise
sk_cow_data is called (similar to ipsec), and buffers are decrypted in
place and copied. splice_read always decrypts in place, since no
buffers are provided to decrypt in to.
sk_poll is overridden, and only returns POLLIN if a full TLS message is
received. Otherwise we wait for strparser to finish reading a full frame.
Actual decryption is only done during recvmsg or splice_read calls.

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e61 (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

usb: changes for v4.17 merge window
Quite a lot happened in this cycle, with a total of 95 non-merge
commits. The most interesting parts are listed below:
Synopsys has been adding better support for USB 3.1 to dwc3. The same
series also sets g_mass_storage's max speed to SSP.
Roger Quadros (TI) added support for dual-role using the OTG block
available in some dwc3 implementations, this makes sure that AM437x
can swap roles in runtime.
We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
the work of Martin Blumenstingl.
We also have a ton of changes in dwc2 (51% of all changes, in
fact). The most interesting part there is the support for
Hibernation (a Synopsys PM feature).
Apart from these, we have our regular set of non-critical fixes all
over the place.

This patch fixes code readability and should have no functional change.

Booting with GICR_CTLR.EnableLPI=1 is usually a bad idea, and may
result in subtle memory corruption. Detecting this is thus pretty
important.
On detecting that LPIs are still enabled, we taint the kernel (because
we're not sure of anything anymore), and try to disable LPIs. This can
fail, as implementations are allowed to implement GICR_CTLR.EnableLPI
as a one-way enable, meaning the redistributors cannot be reprogrammed
with new tables.
Should this happen, we fail probing the redistributor and warn the user
that things are pretty dire.

The correct sequence is to first request locality and only after
that perform cmd_ready handshake, otherwise the hardware will drop
the subsequent message as from the device point of view the cmd_ready
handshake wasn't performed. Symmetrically locality has to be relinquished
only after going idle handshake has completed, this requires that
go_idle has to poll for the completion and as well locality
relinquish has to poll for completion so it is not overridden
in back to back commands flow.
Two wrapper functions are added (request_locality relinquish_locality)
to simplify the error handling.
The issue is only visible on devices that support multiple localities.

Some UDC may want to allocate endpoints dynamically, either because
the HW supports an arbitrary large number or because (like the Aspeed
BMC SoCs), the pool of HW endpoints is shared between multiple gadgets.
The allocation side can be done rather easily using the existing
match_ep() UDC hook.
However we have no good place to "free" them.
This implements a "simple" variant of this, which calls an EP dispose
callback on all EPs associated with a gadget when the composite device
gets unbound.
This is required by my upcoming Aspeed vHub driver.
