I'm exposing some information about NFS clients in pseudofiles. I
expect to eventually have simple tools to help read those pseudofiles.
But it's also helpful if the raw files are human-readable to the extent
possible. It aids debugging and makes them usable on systems that don't
have the latest nfs-utils.
A minor challenge there is opaque client-generated protocol objects like
state owners and client identifiers. Some clients generate those to
include handy information in plain ascii. But they may also include
arbitrary byte sequences.
I think the simplest approach is to limit to isprint(c) && isascii(c)
and escape everything else.
That means you can just cat the file and get something that looks OK.
Also, I'm trying to keep these files legal YAML, which requires them to
UTF-8, and this is a simple way to guarantee that.

Do as the NLM client: allocate and track a struct nlm_lockowner for use as
the fl_owner for locks created by the NLM sever. This allows us to keep
the svid within this structure for matching locks, and will allow us to
track the pid of lockd in a future patch. It should also allow easier
reference of the nlm_host in conflicting locks, and simplify lock hashing
and comparison.

The following is a description of a hang in blk_mq_freeze_queue_wait().
The hang happens on attempt to freeze a queue while another task does
queue unfreeze.
The root cause is an incorrect sequence of percpu_ref_resurrect() and
percpu_ref_kill() and as a result those two can be swapped:
CPU#0 CPU#1
---------------- -----------------
q1 = blk_mq_init_queue(shared_tags)
q2 = blk_mq_init_queue(shared_tags):
blk_mq_add_queue_tag_set(shared_tags):
blk_mq_update_tag_set_depth(shared_tags):
list_for_each_entry()
blk_mq_freeze_queue(q1)
> percpu_ref_kill()
> blk_mq_freeze_queue_wait()
blk_cleanup_queue(q1)
blk_mq_freeze_queue(q1)
> percpu_ref_kill()
^^^^^^ freeze_depth can't guarantee the order
blk_mq_unfreeze_queue()
> percpu_ref_resurrect()
> blk_mq_freeze_queue_wait()
^^^^^^ Hang here!!!!
This wrong sequence raises kernel warning:
percpu_ref_kill_and_confirm called more than once on blk_queue_usage_counter_release!
WARNING: CPU: 0 PID: 11854 at lib/percpu-refcount.c:336 percpu_ref_kill_and_confirm+0x99/0xb0
But the most unpleasant effect is a hang of a blk_mq_freeze_queue_wait(),
which waits for a zero of a q_usage_counter, which never happens
because percpu-ref was reinited (instead of being killed) and stays in
PERCPU state forever.
How to reproduce:
- "insmod null_blk.ko shared_tags=1 nr_devices=0 queue_mode=2"
- cpu0: python Script.py 0; taskset the corresponding process running on cpu0
- cpu1: python Script.py 1; taskset the corresponding process running on cpu1
Script.py:
------
#!/usr/bin/python3
import os
import sys
while True:
on = "echo 1 > /sys/kernel/config/nullb/%s/power" % sys.argv[1]
off = "echo 0 > /sys/kernel/config/nullb/%s/power" % sys.argv[1]
os.system(on)

Here are series of patches that add SPDX tags to different kernel files,
based on two different things:
- SPDX entries are added to a bunch of files that we missed a year ago
that do not have any license information at all.
These were either missed because the tool saw the MODULE_LICENSE()
tag, or some EXPORT_SYMBOL tags, and got confused and thought the
file had a real license, or the files have been added since the last
big sweep, or they were Makefile/Kconfig files, which we didn't
touch last time.
- Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
tools can determine the license text in the file itself. Where this
happens, the license text is removed, in order to cut down on the
700+ different ways we have in the kernel today, in a quest to get
rid of all of these.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on the
patches are reviewers.
The reason for these "large" patches is if we were to continue to
progress at the current rate of change in the kernel, adding license
tags to individual files in different subsystems, we would be finished
in about 10 years at the earliest.
There will be more series of these types of patches coming over the next
few weeks as the tools and reviewers crunch through the more "odd"
variants of how to say "GPLv2" that developers have come up with over
the years, combined with other fun oddities (GPL + a BSD disclaimer?)
that are being unearthed, with the goal for the whole kernel to be
cleaned up.
These diffstats are not small, 3840 files are touched, over 10k lines
removed in just 24 patches.

Pankaj reports that starting with commit ad428cdb52 "dax: Check the
end of the block-device capacity with dax_direct_access()" device-mapper
no longer allows dax operation. This results from the stricter checks in
__bdev_dax_supported() that validate that the start and end of a
block-device map to the same 'pagemap' instance.
Teach the dax-core and device-mapper to validate the 'pagemap' on a
per-target basis. This is accomplished by refactoring the
bdev_dax_supported() internals into generic_fsdax_supported() which
takes a sector range to validate. Consequently generic_fsdax_supported()
is suitable to be used in a device-mapper ->iterate_devices() callback.
A new ->dax_supported() operation is added to allow composite devices to
split and route upper-level bdev_dax_supported() requests.
Fixes: ad428cdb52 ("dax: Check the end of the block-device...")

CONFIG_OF, so I'm doing so now.

Patch series "improve vmap allocation", v3.
Objective
---------
Please have a look for the description at:
https://lkml.org/lkml/2018/10/19/786
but let me also summarize it a bit here as well.
The current implementation has O(N) complexity. Requests with different
permissive parameters can lead to long allocation time. When i say
"long" i mean milliseconds.
Description
-----------
This approach organizes the KVA memory layout into free areas of the
1-ULONG_MAX range, i.e. an allocation is done over free areas lookups,
instead of finding a hole between two busy blocks. It allows to have
lower number of objects which represent the free space, therefore to have
less fragmented memory allocator. Because free blocks are always as large
as possible.
It uses the augment tree where all free areas are sorted in ascending
order of va->va_start address in pair with linked list that provides
O(1) access to prev/next elements.
Since the tree is augment, we also maintain the "subtree_max_size" of VA
that reflects a maximum available free block in its left or right
sub-tree. Knowing that, we can easily traversal toward the lowest (left
most path) free area.
Allocation: ~O(log(N)) complexity. It is sequential allocation method
therefore tends to maximize locality. The search is done until a first
suitable block is large enough to encompass the requested parameters.
Bigger areas are split.
I copy paste here the description of how the area is split, since i
described it in https://lkml.org/lkml/2018/10/19/786
<snip>
A free block can be split by three different ways. Their names are
FL_FIT_TYPE, LE_FIT_TYPE/RE_FIT_TYPE and NE_FIT_TYPE, i.e. they
correspond to how requested size and alignment fit to a free block.
FL_FIT_TYPE - in this case a free block is just removed from the free
list/tree because it fully fits. Comparing with current design there is
an extra work with rb-tree updating.
LE_FIT_TYPE/RE_FIT_TYPE - left/right edges fit. In this case what we do
is just cutting a free block. It is as fast as a current design. Most of
the vmalloc allocations just end up with this case, because the edge is
always aligned to 1.
NE_FIT_TYPE - Is much less common case. Basically it happens when
requested size and alignment does not fit left nor right edges, i.e. it
is between them. In this case during splitting we have to build a
remaining left free area and place it back to the free list/tree.
Comparing with current design there are two extra steps. First one is we
have to allocate a new vmap_area structure. Second one we have to insert
that remaining free block to the address sorted list/tree.
In order to optimize a first case there is a cache with free_vmap objects.
Instead of allocating from slab we just take an object from the cache and
reuse it.
Second one is pretty optimized. Since we know a start point in the tree
we do not do a search from the top. Instead a traversal begins from a
rb-tree node we split.
<snip>
De-allocation. ~O(log(N)) complexity. An area is not inserted straight
away to the tree/list, instead we identify the spot first, checking if it
can be merged around neighbors. The list provides O(1) access to
prev/next, so it is pretty fast to check it. Summarizing. If merged then
large coalesced areas are created, if not the area is just linked making
more fragments.
There is one more thing that i should mention here. After modification of
VA node, its subtree_max_size is updated if it was/is the biggest area in
its left or right sub-tree. Apart of that it can also be populated back
to upper levels to fix the tree. For more details please have a look at
the __augment_tree_propagate_from() function and the description.
Tests and stressing
-------------------
I use the "test_vmalloc.sh" test driver available under
"tools/testing/selftests/vm/" since 5.1-rc1 kernel. Just trigger "sudo
./test_vmalloc.sh" to find out how to deal with it.
Tested on different platforms including x86_64/i686/ARM64/x86_64_NUMA.
Regarding last one, i do not have any physical access to NUMA system,
therefore i emulated it. The time of stressing is days.
If you run the test driver in "stress mode", you also need the patch that
is in Andrew's tree but not in Linux 5.1-rc1. So, please apply it:
http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/commit/?id=e0cf7749bade6da318e98e934a24d8b62fab512c
After massive testing, i have not identified any problems like memory
leaks, crashes or kernel panics. I find it stable, but more testing would
be good.
Performance analysis
--------------------
I have used two systems to test. One is i5-3320M CPU @ 2.60GHz and
another is HiKey960(arm64) board. i5-3320M runs on 4.20 kernel, whereas
Hikey960 uses 4.15 kernel. I have both system which could run on 5.1-rc1
as well, but the results have not been ready by time i an writing this.
Currently it consist of 8 tests. There are three of them which correspond
to different types of splitting(to compare with default). We have 3
ones(see above). Another 5 do allocations in different conditions.
a) sudo ./test_vmalloc.sh performance
When the test driver is run in "performance" mode, it runs all available
tests pinned to first online CPU with sequential execution test order. We
do it in order to get stable and repeatable results. Take a look at time
difference in "long_busy_list_alloc_test". It is not surprising because
the worst case is O(N).
# i5-3320M
How many cycles all tests took:
CPU0=646919905370(default) cycles vs CPU0=193290498550(patched) cycles
# See detailed table with results here:

ftp://vps418301.ovh.net/incoming/vmap_test_results_v2/i5-3320M_performance_patched.txt
# Hikey960 8x CPUs
How many cycles all tests took:
CPU0=3478683207 cycles vs CPU0=463767978 cycles

ftp://vps418301.ovh.net/incoming/vmap_test_results_v2/HiKey960_performance_patched.txt
b) time sudo ./test_vmalloc.sh test_repeat_count=1
With this configuration, all tests are run on all available online CPUs.
Before running each CPU shuffles its tests execution order. It gives
random allocation behaviour. So it is rough comparison, but it puts in
the picture for sure.
# i5-3320M

real 101m22.813s real 0m56.805s
user 0m0.011s user 0m0.015s

# Hikey960 8x CPUs
<default> vs <patched>
real unknown real 4m25.214s
user unknown user 0m0.011s
sys unknown sys 0m0.670s
I did not manage to complete this test on "default Hikey960" kernel
version. After 24 hours it was still running, therefore i had to cancel
it. That is why real/user/sys are "unknown".
This patch (of 3):
Currently an allocation of the new vmap area is done over busy list
iteration(complexity O(n)) until a suitable hole is found between two busy
areas. Therefore each new allocation causes the list being grown. Due to
over fragmented list and different permissive parameters an allocation can
take a long time. For example on embedded devices it is milliseconds.
This patch organizes the KVA memory layout into free areas of the
1-ULONG_MAX range. It uses an augment red-black tree that keeps blocks
sorted by their offsets in pair with linked list keeping the free space in
order of increasing addresses.
Nodes are augmented with the size of the maximum available free block in
its left or right sub-tree. Thus, that allows to take a decision and
traversal toward the block that will fit and will have the lowest start
address, i.e. it is sequential allocation.
Allocation: to allocate a new block a search is done over the tree until a
suitable lowest(left most) block is large enough to encompass: the
requested size, alignment and vstart point. If the block is bigger than
requested size - it is split.
De-allocation: when a busy vmap area is freed it can either be merged or
inserted to the tree. Red-black tree allows efficiently find a spot
whereas a linked list provides a constant-time access to previous and next
blocks to check if merging can be done. In case of merging of
de-allocated memory chunk a large coalesced area is created.
Complexity: ~O(log(N))

To avoid any ambiguity between vport index and vport number,
rename functions that had vport, to vport_num or vport_index appropriately.
vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return
type to u16.
vport_index is an int in vport array. Hence change input type of vport
index in mlx5_eswitch_index_to_vport_num() to int.
Correct multiple eswitch representor interfaces use type u16 of
rep->vport as type int vport_index.
Send vport FW commands with correct eswitch u16 vport_num instead
host int vport_index.
