including my patch set for protecting glock gl_object and Andreas
Gruenbacher's patch set to fix the long-standing shrink- slab hang,
plus a bunch of assorted bugs and cleanups.
Summary:
- I fixed a bug whereby an IO error would lead to a double-brelse.
- Andreas Gruenbacher made a minor cleanup to call his relatively new
function, gfs2_holder_initialized, rather than doing it manually.
This was just missed by a previous patch set.
- Jan Kara fixed a bug whereby the SGID was being cleared when
inheriting ACLs.
- Andreas found a bug and fixed it in his previous patch, "Get rid of
flush_delayed_work in gfs2_evict_inode". A call to
flush_delayed_work was deleted from *gfs2_inode_lookup and added to
gfs2_create_inode.
- Wang Xibo found and fixed a list_add call in inode_go_lock that
specified the parameters in the wrong order.
- Coly Li submitted a patch to add the REQ_PRIO to some of GFS2's
metadata reads that were accidentally missing them.
- I submitted a 4-patch set to protect the glock gl_object field.
GFS2 was setting and checking gl_object with no locking mechanism,
so the value was occasionally stomped on, which caused file system
corruption.
- I submitted a small cleanup to function gfs2_clear_rgrpd. It was
needlessly adding rgrp glocks to the lru list, then pulling them
back off immediately. The rgrp glocks don't use the lru list
anyway, so doing so was just a waste of time.
- I submitted a patch that checks the GLOF_LRU flag on a glock before
trying to remove it from the lru_list. This avoids a lot of
unnecessary spin_lock contention.
- I submitted a patch to delete GFS2's debugfs files only after we
evict all the glocks. Before this patch, GFS2 would delete the
debugfs files, and if unmount hung waiting for a glock, there was
no way to debug the problem. Now, if a hang occurs during umount,
we can examine the debugfs files to figure out why it's hung.
- Andreas Gruenbacher submitted a patch to fix some trivial typos.
- Andreas also submitted a five-part patch set to fix the
longstanding hang involving the slab shrinker: dlm requires memory,
calls the inode shrinker, which calls gfs2's evict, which calls
back into DLM before it can evict an inode.
- Abhi Das submitted a patch to forcibly flush the active items list
to relieve memory pressure. This fixes a long-standing bug whereby
GFS2 was getting hung permanently in balance_dirty_pages.
- Thomas Tai submitted a patch to fix a slab corruption problem due
to a residual pointer left in the lock_dlm lockstruct.
- I submitted a patch to withdraw the file system if IO errors are
encountered while writing to the journals or statfs system file
which were previously not being sent back up. Before, some IO
errors were sometimes not be detected for several hours, and at
recovery time, the journal errors made journal replay impossible.
- Andreas has a patch to fix an annoying format-truncation compiler
warning so GFS2 compiles cleanly.
- I have a patch that fixes a handful of sparse compiler warnings.
- Andreas fixed up an useless gl_object warning caused by an earlier
patch.
- Arvind Yadav added a patch to properly constify our rhashtable
params declare.
- I added a patch to fix a regression caused by the non-recursive
delete and truncate patch that caused file system blocks to not be
properly freed.
- Ernesto A. Fernández added a patch to fix a place where GFS2 would
send back the wrong return code setting extended attributes.
- Ernesto also added a patch to fix a case in which GFS2 was
improperly setting an inode's i_mode, potentially granting access
to the wrong users"

i40e: avoid NVM acquire deadlock during NVM update
X722 devices use the AdminQ to access the NVM, and this requires taking
the AdminQ lock. Because of this, we lock the AdminQ during
i40e_read_nvm(), which is also called in places where the lock is
already held, such as the firmware update path which wants to lock once
and then unlock when finished after performing several tasks.
Although this should have only affected X722 devices, commit
96a39aed25e6 ("i40e: Acquire NVM lock before reads on all devices",
2016-12-02) added locking for all NVM reads, regardless of device
family.
This resulted in us accidentally causing NVM acquire timeouts on all
devices, causing failed firmware updates which left the eeprom in
a corrupt state.
Create unsafe non-locked variants of i40e_read_nvm_word and
i40e_read_nvm_buffer, __i40e_read_nvm_word and __i40e_read_nvm_buffer
respectively. These variants will not take the NVM lock and are expected
to only be called in places where the NVM lock is already held if
needed.
Since the only caller of i40e_read_nvm_buffer() was in such a path,
remove it entirely in favor of the unsafe version. If necessary we can
always add it back in the future.
Additionally, we now need to hold the NVM lock in i40e_validate_checksum
because the call to i40e_calc_nvm_checksum now assumes that the NVM lock
is held. We can further move the call to read I40E_SR_SW_CHECKSUM_WORD
up a bit so that we do not need to acquire the NVM lock twice.
This should resolve firmware updates and also fix potential raise that
could have caused the driver to report an invalid NVM checksum upon
driver load.

vhost_net: correctly check tx avail during rx busy polling
We check tx avail through vhost_enable_notify() in the past which is
wrong since it only checks whether or not guest has filled more

rxrpc: Make service connection lookup always check for retry
When an RxRPC service packet comes in, the target connection is looked up
by an rb-tree search under RCU and a read-locked seqlock; the seqlock retry
check is, however, currently skipped if we got a match, but probably
shouldn't be in case the connection we found gets replaced whilst we're
doing a search.
Make the lookup procedure always go through need_seqretry(), even if the
lookup was successful. This makes sure we always pick up on a write-lock

On the other hand, since we don't take a ref on the object, but rely on RCU

The wrong register is checked for the Tx flow control bit,

First, link flow control (i.e. handling of Rx/Tx link level pause frames)

port output queue they want to use. Currently only Broadcom tags utilize that
information.

"This is the bulk of the GPIO changes for the v4.14 cycle.
Not so much changes this time, phew. David Daney and Bartosz
Golaszewski did all the really interesting work in infrastructure
improvement across GPIO and IRQ core, hats off for them and to tglx
and Marc Z for general help with these patch sets.
Core changes:
- Allow the GPIO irqchip to allocate IRQs dynamically. This is an
important change on systems where only a restricted number of IRQs,
lesser than the number of GPIO lines, can be utilized. Now we can
allocate these on a first-come-first-served basis instead of
hogging up valuable IRQ lines.
- Serious fix-up of the kerneldoc documentation and inclusion into
the kerneldoc builds.
- Pulled in the IRQ simulator from the IRQ core tree and use this in
the GPIO mockup driver for exhaustive testing of interrupt
abilities.
New drivers:
- New driver for ThunderX and OCTEON-TX. This is especially
interesting as it picks up improvements from the IRQ core that
allow us to handle fasteoi ACKs upwards in a hierarchy when there
are IRQ flag latches on several levels in a hierarchy. Very
interesting work here.
- New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
Misc:
- Several fixes and improvements for Xilinx Zynq GPIO.
- Support an enablement GPIO for the 74x164 GPIO.
- Switch a bunch of chips to use devres to allocate irq descriptors.
- A bunch of constification fixes"

This patch set fixes some basic issues with __skb_flow_dissect function.
Items addressed:
- Cleanup control flow in the function; in particular eliminate a

- Add limits for number of encapsulations and headers that can be

v2:
- Simplify the logic for limits on flow dissection. Just set the

flow_dissector: Add limit for number of headers to dissect
In flow dissector there are no limits to the number of nested
encapsulations or headers that might be dissected which makes for a
nice DOS attack. This patch sets a limit of the number of headers
that flow dissector will parse.
Headers includes network layer headers, transport layer headers, shim
headers for encapsulation, IPv6 extension headers, etc. The limit for
maximum number of headers to parse has be set to fifteen to account for
a reasonable number of encapsulations, extension headers, VLAN,
in a packet. Note that this limit does not supercede the STOP_AT_*
flags which may stop processing before the headers limit is reached.

Pull arm64 updates from Catalin Marinas:
- VMAP_STACK support, allowing the kernel stacks to be allocated in the
vmalloc space with a guard page for trapping stack overflows. One of
the patches introduces THREAD_ALIGN and changes the generic
alloc_thread_stack_node() to use this instead of THREAD_SIZE (no
functional change for other architectures)
- Contiguous PTE hugetlb support re-enabled (after being reverted a
couple of times). We now have the semantics agreed in the generic mm
layer together with API improvements so that the architecture code
can detect between contiguous and non-contiguous huge PTEs
- Initial support for persistent memory on ARM: DC CVAP instruction
exposed to user space (HWCAP) and the in-kernel pmem API implemented
- raid6 improvements for arm64: faster algorithm for the delta syndrome
and implementation of the recovery routines using Neon
- FP/SIMD refactoring and removal of support for Neon in interrupt
context. This is in preparation for full SVE support
- PTE accessors converted from inline asm to cmpxchg so that we can use
LSE atomics if available (ARMv8.1)
- Perf support for Cortex-A35 and A73
- Non-urgent fixes and cleanups

bpf: fix numa_node validation
syzkaller reported crashes in bpf map creation or map update [1]
Problem is that nr_node_ids is a signed integer,
NUMA_NO_NODE is also an integer, so it is very tempting
to declare numa_node as a signed integer.
This means the typical test to validate a user provided value :
if (numa_node != NUMA_NO_NODE &&
(numa_node >= nr_node_ids ||
!node_online(numa_node)))
must be written :
if (numa_node != NUMA_NO_NODE &&

Netfilter updates for next-net (part 2)
The following patchset contains Netfilter updates for net-next. This
patchset includes updates for nf_tables, removal of
CONFIG_NETFILTER_DEBUG and a new mode for xt_hashlimit. More
specifically, they:
1) Add new rate match mode for hashlimit, this introduces a new revision
for this match. The idea is to stop matching packets until ratelimit
criteria stands true. Patch from Vishwanath Pai.
2) Add ->select_ops indirection to nf_tables named objects, so we can
choose between different flavours of the same object type, patch from
Pablo M. Bermudo.
3) Shorter function names in nft_limit, basically:
s/nft_limit_pkt_bytes/nft_limit_bytes, also from Pablo M. Bermudo.
4) Add new stateful limit named object type, this allows us to create
limit policies that you can identify via name, also from Pablo.
5) Remove unused hooknum parameter in conntrack ->packet indirection.
From Florian Westphal.
6) Patches to remove CONFIG_NETFILTER_DEBUG and macros such as
IP_NF_ASSERT and IP_NF_ASSERT. From Varsha Rao.
7) Add nf_tables_updchain() helper function and use it from
nf_tables_newchain() to make it more maintainable. Similarly,
add nf_tables_addchain() and use it too.
8) Add new netlink NLM_F_NONREC flag, this flag should only be used for
deletion requests, specifically, to support non-recursive deletion.
Based on what we discussed during NFWS'17 in Faro.
9) Use NLM_F_NONREC from table and sets in nf_tables.
10) Support for recursive chain deletion. Table and set deletion
commands come with an implicit content flush on deletion, while
chains do not. This patch addresses this inconsistency by adding
the code to perform recursive chain deletions. This also comes with
the bits to deal with the new NLM_F_NONREC netlink flag.

Pull x86 mm changes from Ingo Molnar:
"PCID support, 5-level paging support, Secure Memory Encryption support
The main changes in this cycle are support for three new, complex
hardware features of x86 CPUs:
- Add 5-level paging support, which is a new hardware feature on
upcoming Intel CPUs allowing up to 128 PB of virtual address space
and 4 PB of physical RAM space - a 512-fold increase over the old
limits. (Supercomputers of the future forecasting hurricanes on an
ever warming planet can certainly make good use of more RAM.)
Many of the necessary changes went upstream in previous cycles,
v4.14 is the first kernel that can enable 5-level paging.
This feature is activated via CONFIG_X86_5LEVEL=y - disabled by
default.
(By Kirill A. Shutemov)
- Add 'encrypted memory' support, which is a new hardware feature on
upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system
RAM to be encrypted and decrypted (mostly) transparently by the
CPU, with a little help from the kernel to transition to/from
encrypted RAM. Such RAM should be more secure against various
attacks like RAM access via the memory bus and should make the
radio signature of memory bus traffic harder to intercept (and
decrypt) as well.
This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled
by default.
(By Tom Lendacky)
- Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a
hardware feature that attaches an address space tag to TLB entries
and thus allows to skip TLB flushing in many cases, even if we
switch mm's.
(By Andy Lutomirski)
All three of these features were in the works for a long time, and
it's coincidence of the three independent development paths that they
are all enabled in v4.14 at once"
