"There are a several user visible changes, the rest is mostly invisible
and continues to clean up the whole code base.
User visible changes:
- new mount option nossd_spread (pair for ssd_spread)
- mount option subvolid will detect junk after the number and fail
the mount
- add message after cancelled device replace
- direct module dependency on libcrc32, removed own crc wrappers
- removed user space transaction ioctls
- use lighter locking when reading /proc/self/mounts, RCU instead of
mutex to avoid unnecessary contention
Enhancements:
- skip writeback of last page when truncating file to same size
- send: do not issue unnecessary truncate operations
- mount option token specifiers: use %u for unsigned values, more
validation
- selftests: more tree block validations
qgroups:
- preparatory work for splitting reservation types for data and
metadata, this should allow for more accurate tracking and fix some
issues with underflows or do further enhancements
- split metadata reservations for started and joined transaction so
they do not get mixed up and are accounted correctly at commit time
- with the above, it's possible to revert patch that potentially
deadlocks when trying to make more space by explicitly committing
when the quota limit is hit
- fix root item corruption when multiple same source snapshots are
created with quota enabled
RAID56:
- make sure target is identical to source when raid56 rebuild fails
after dev-replace

block-by-block
- make more use of cached data when rebuilding from a missing device
Fixes:
- null pointer deref when device replace target is missing
- fix fsync after hole punching when using no-holes feature
- fix lockdep splat when allocating percpu data with wrong GFP flags

"Here's the first round of fixes for XFS for 4.17.
The biggest new features this time around are the addition of lazytime
support, further enhancement of the on-disk inode metadata verifiers,

scrub code and elsewhere.
This series has been run through a full xfstests run over the weekend
and through a quick xfstests run against this morning's master, with
no major failures reported.

The __net_initdata section cannot currently be used for structures that

WARNING: vmlinux.o(.text+0x868c34): Section mismatch in reference from the function nsim_devlink_exit() to the (unknown reference) .init.data:(unknown)
The function nsim_devlink_exit() references
the (unknown reference) __initdata (unknown).
This is often because nsim_devlink_exit lacks a __initdata
annotation or the annotation of (unknown) is wrong.
WARNING: vmlinux.o(.text+0x868c64): Section mismatch in reference from the function nsim_devlink_init() to the (unknown reference) .init.data:(unknown)
WARNING: vmlinux.o(.text+0x8692bc): Section mismatch in reference from the function nsim_fib_exit() to the (unknown reference) .init.data:(unknown)
WARNING: vmlinux.o(.text+0x869300): Section mismatch in reference from the function nsim_fib_init() to the (unknown reference) .init.data:(unknown)
As that warning tells us, discarding the structure after a module is
loaded would lead to a undefined behavior when that module is removed.
It might be possible to change that annotation so it has no effect for
loadable modules, but I have not figured out exactly how to do that, and
we want this to be fixed in -rc1.
This just removes the annotations, just like we do for all other such
modules.

Giving an integer to proc_doulongvec_minmax() is dangerous on 64bit arches,
since linker might place next to it a non zero value preventing a change
to ip6frag_low_thresh.
ip6frag_low_thresh is not used anymore in the kernel, but we do not
want to prematuraly break user scripts wanting to change it.
Since specifying a minimal value of 0 for proc_doulongvec_minmax()
is moot, let's remove these zero values in all defrag units.

done by __ip_append_data()") and commit 1f4c6eb240 ("ipv6:
factorize sk_wmem_alloc updates done by __ip6_append_data()"),
when transmitting sub MTU datagram, an addtional, unneeded atomic
operation is performed in ip*_append_data() to update wmem_alloc:
in the above condition the delta is 0.
The above cause small but measurable performance regression in UDP
xmit tput test with packet size below MTU.
This change avoids such overhead updating wmem_alloc only if
wmem_alloc_delta is non zero.
The error path is left intentionally unmodified: it's a slow path
and simplicity is preferred to performances.

The new of_get_nvmem_mac_address() helper function causes a link error
with CONFIG_NVMEM=m:
drivers/of/of_net.o: In function `of_get_nvmem_mac_address':
of_net.c:(.text+0x168): undefined reference to `of_nvmem_cell_get'
of_net.c:(.text+0x19c): undefined reference to `nvmem_cell_read'
of_net.c:(.text+0x1a8): undefined reference to `nvmem_cell_put'
I could not come up with a good solution for this, as the code is always
built-in. Using an #if IS_REACHABLE() check around it would solve the
link time issue but then stop it from working in that configuration.
Making of_nvmem_cell_get() an inline function could also solve that, but
seems a bit ugly since it's somewhat larger than most inline functions,
and it would just bring that problem into the callers. Splitting the
function into a separate file might be an alternative.
This uses the big hammer by making CONFIG_NVMEM itself a 'bool' symbol,
which avoids the problem entirely but makes the vmlinux larger for anyone

The NSP default buffer is a piece of NFP memory where additional
command data can be placed. Its format has been copied from
host buffer, but the PCIe selection bits do not make sense in
this case. If those get masked out from a NFP address - writes
to random place in the chip memory may be issued and crash the
device.
Even in the general NSP buffer case, it doesn't make sense to have the
PCIe selection bits there anymore. These are unused at the moment, and
when it becomes necessary, the PCIe selection bits should rather be
moved to another register to utilise more bits for the buffer address.
This has never been an issue because the buffer used to be
allocated in memory with less-than-38-bit-long address but that
is about to change.

The culprit is quite simple: The driver tries to access the phy left and right,
but only actually has a working reference to it when the device is up.
The fix thus is quite simple too: Get a reference to the phy on probe already
and keep it even when the device is going down.

When an item of struct tipc_subscription is created, we fail to

never been a problem, since the items are just added to a root
object by list_add(), which does not require the addee list to be
pre-initialized. However, syzbot is provoking situations where this
addition fails, whereupon the attempted removal if the item from
the list causes a crash.
This problem seems to always have been around, despite that the code
for creating this object was rewritten in commit 242e82cc95 ("tipc:

We fix this for that commit by initializing the two lists properly.

====================
ipv6: udp: set dst cache for a connected sk if current not valid
A new RTF_CACHE route can be created with the socket's dst cache
update between the below calls in udpv6_sendmsg(), when datagram
sending results to ICMPV6_PKT_TOOBIG error:
dst = ip6_sk_dst_lookup_flow(...)
...
release_dst:
if (dst) {
if (connected) {
ip6_dst_store(sk, dst)
Therefore, the new socket's dst cache reset to the old one on
"release_dst:".
The first three patches prepare the code to store dst cache
with ip6_sk_dst_lookup_flow():
* the first patch adds ip6_sk_dst_store_flow() function with
commonly used source and destiantion addresses checks using
the flow information.
* the second patch adds a new argument to ip6_sk_dst_lookup_flow()
and ability to store dst in the socket's cache. Also, the two
users of the function are updated without enabling the new
behavior: pingv6_sendmsg() and udpv6_sendmsg().
* the third patch makes 'connected' variable in udpv6_sendmsg()
to be consistent with ip6_sk_dst_store_flow(), changes its type
from int to bool.
The last patch contains the actual fix that removes sk dst cache
update in the end of udpv6_sendmsg(), and allows to do it in
ip6_sk_dst_lookup_flow().
v6: * use bool type for a new parameter in ip_sk_dst_lookup_flow()
* add one more patch to convert 'connected' variable in
udpv6_sendmsg() from int to bool type. If it shouldn't be
here I will resend it when the net-next is opened.
v5: * relocate ip6_sk_dst_store_flow() to net/ipv6/route.c and
rename ip6_dst_store_flow() to ip6_sk_dst_store_flow() as
suggested by Martin
v4: * fix the error in the build of ip_dst_store_flow() reported by
kbuild test robot due to missing checks for CONFIG_IPV6: add
new function to ip6_output.c instead of ip6_route.h
* add 'const' to struct flowi6 in ip6_dst_store_flow()
* minor commit messages fixes
v3: * instead of moving ip6_dst_store() above udp_v6_send_skb(),
update socket's dst cache inside ip6_sk_dst_lookup_flow()
if the current one is invalid
* the issue not reproduced in 4.1, but starting from 4.2. Add
one more 'Fixes:' commit that creates new RTF_CACHE route.
Though, it is also mentioned in the first one

A new RTF_CACHE route can be created between ip6_sk_dst_lookup_flow()
and ip6_dst_store() calls in udpv6_sendmsg(), when datagram sending
results to ICMPV6_PKT_TOOBIG error:
udp_v6_send_skb(), for example with vti6 tunnel:
vti6_xmit(), get ICMPV6_PKT_TOOBIG error
skb_dst_update_pmtu(), can create a RTF_CACHE clone
icmpv6_send()
...
udpv6_err()
ip6_sk_update_pmtu()
ip6_update_pmtu(), can create a RTF_CACHE clone
...
ip6_datagram_dst_update()
ip6_dst_store()
And after commit 33c162a980 ("ipv6: datagram: Update dst cache of
a connected datagram sk during pmtu update"), the UDPv6 error handler
can update socket's dst cache, but it can happen before the update in
the end of udpv6_sendmsg(), preventing getting the new dst cache on
the next udpv6_sendmsg() calls.
In order to fix it, save dst in a connected socket only if the current
socket's dst cache is invalid.
The previous patch prepared ip6_sk_dst_lookup_flow() to do that with
the new argument, and this patch enables it in udpv6_sendmsg().

Pull namespace updates from Eric Biederman:
"There was a lot of work this cycle fixing bugs that were discovered
after the merge window and getting everything ready where we can
reasonably support fully unprivileged fuse. The bug fixes you already
have and much of the unprivileged fuse work is coming in via other
trees.
Still left for fully unprivileged fuse is figuring out how to cleanly
handle .set_acl and .get_acl in the legacy case, and properly handling
of evm xattrs on unprivileged mounts.
Included in the tree is a cleanup from Alexely that replaced a linked
list with a statically allocated fix sized array for the pid caches,
which simplifies and speeds things up.
Then there is are some cleanups and fixes for the ipc namespace. The
motivation was that in reviewing other code it was discovered that
access ipc objects from different pid namespaces recorded pids in such
a way that when asked the wrong pids were returned. In the worst case
there has been a measured 30% performance impact for sysvipc
semaphores. Other test cases showed no measurable performance impact.
Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc
performance both gave the nod that this is good enough.
Casey Schaufler and James Morris have given their approval to the LSM
side of the changes.
I simplified the types and the code dealing with sysvipc to pass just
kern_ipc_perm for all three types of ipc. Which reduced the header
dependencies throughout the kernel and simplified the lsm code.
Which let me work on the pid fixes without having to worry about
trivial changes causing complete kernel recompiles"

This does add an IPMI BMC server-side driver, to allow a Linux
system to act as an IPMI controller. That's the biggest change,
but it is just a new driver that is fairly narrow in use.
The other largish change is removing ACPI SPMI probe support,
which should have never really been there in the beginning.
