zswap will always try to shrink pool when zswap is full. If there is a
high pressure on zswap it will result in flipping pages in and out zswap
pool without any real benefit, and the overall system performance will
drop. The previous discussion on this subject [1] ended up with a
suggestion to implement a sort of hysteresis to refuse taking pages into
zswap pool until it has sufficient space if the limit has been hit.
This is my take on this.
Hysteresis is controlled with a sysfs-configurable parameter (namely,
/sys/kernel/debug/zswap/accept_threhsold_percent). It specifies the
threshold at which zswap would start accepting pages again after it
became full. Setting this parameter to 100 disables the hysteresis and
sets the zswap behavior to pre-hysteresis state.

In order to provide a clearer, more symmetric API for pinning and
unpinning DMA pages. This way, pin_user_pages*() calls match up with
unpin_user_pages*() calls, and the API is a lot closer to being
self-explanatory.

Introduce pin_user_pages*() variations of get_user_pages*() calls, and
also pin_longterm_pages*() variations.
For now, these are placeholder calls, until the various call sites are
converted to use the correct get_user_pages*() or pin_user_pages*() API.
These variants will eventually all set FOLL_PIN, which is also
introduced, and thoroughly documented.
pin_user_pages()
pin_user_pages_remote()
pin_user_pages_fast()
All pages that are pinned via the above calls, must be unpinned via
put_user_page().
The underlying rules are:
* FOLL_PIN is a gup-internal flag, so the call sites should not directly
set it. That behavior is enforced with assertions.
* Call sites that want to indicate that they are going to do DirectIO
("DIO") or something with similar characteristics, should call a
get_user_pages()-like wrapper call that sets FOLL_PIN. These wrappers
will:
* Start with "pin_user_pages" instead of "get_user_pages". That
makes it easy to find and audit the call sites.
* Set FOLL_PIN
* For pages that are received via FOLL_PIN, those pages must be returned
via put_user_page().
Thanks to Jan Kara and Vlastimil Babka for explaining the 4 cases in
this documentation. (I've reworded it and expanded upon it.)

Pull KVM updates from Paolo Bonzini:
"This is the first batch of KVM changes.
ARM:
- cleanups and corner case fixes.
PPC:
- Bugfixes
x86:
- Support for mapping DAX areas with large nested page table entries.
- Cleanups and bugfixes here too. A particularly important one is a
fix for FPU load when the thread has TIF_NEED_FPU_LOAD. There is
also a race condition which could be used in guest userspace to
exploit the guest kernel, for which the embargo expired today.
- Fast path for IPI delivery vmexits, shaving about 200 clock cycles
from IPI latency.
- Protect against "Spectre-v1/L1TF" (bring data in the cache via
speculative out of bound accesses, use L1TF on the sibling
hyperthread to read it), which unfortunately is an even bigger
whack-a-mole game than SpectreV1.
Sean continues his mission to rewrite KVM. In addition to a sizable
number of x86 patches, this time he contributed a pretty large
refactoring of vCPU creation that affects all architectures but should
not have any visible effect.
s390 will come next week together with some more x86 patches"

Pull x86 MPX removal from Dave Hansen:
"MPX requires recompiling applications, which requires compiler
support. Unfortunately, GCC 9.1 is expected to be be released without
support for MPX. This means that there was only a relatively small
window where folks could have ever used MPX. It failed to gain wide
adoption in the industry, and Linux was the only mainstream OS to ever
support it widely.
Support for the feature may also disappear on future processors.
This set completes the process that we started during the 5.4 merge
window when the MPX prctl()s were removed. XSAVE support is left in
place, which allows MPX-using KVM guests to continue to function"

Pull f2fs updates from Jaegeuk Kim:
"In this series, we've implemented transparent compression
experimentally. It supports LZO and LZ4, but will add more later as we
investigate in the field more.
At this point, the feature doesn't expose compressed space to user
directly in order to guarantee potential data updates later to the
space. Instead, the main goal is to reduce data writes to flash disk
as much as possible, resulting in extending disk life time as well as
relaxing IO congestion.
Alternatively, we're also considering to add ioctl() to reclaim
compressed space and show it to user after putting the immutable bit.
Enhancements:
- add compression support
- avoid unnecessary locks in quota ops
- harden power-cut scenario for zoned block devices
- use private bio_set to avoid IO congestion
- replace GC mutex with rwsem to serialize callers
Bug fixes:
- fix dentry consistency and memory corruption in rename()'s error case
- fix wrong swap extent reports
- fix casefolding bugs
- change lock coverage to avoid deadlock
- avoid GFP_KERNEL under f2fs_lock_op
And, we've cleaned up sysfs entries to prepare no debugfs"

From Boris Ostrovsky:
The KVM hypervisor may provide a guest with ability to defer remote TLB
flush when the remote VCPU is not running. When this feature is used,
the TLB flush will happen only when the remote VPCU is scheduled to run
again. This will avoid unnecessary (and expensive) IPIs.
Under certain circumstances, when a guest initiates such deferred action,
the hypervisor may miss the request. It is also possible that the guest
may mistakenly assume that it has already marked remote VCPU as needing
a flush when in fact that request had already been processed by the
hypervisor. In both cases this will result in an invalid translation
being present in a vCPU, potentially allowing accesses to memory locations
in that guest's address space that should not be accessible.
Note that only intra-guest memory is vulnerable.
The five patches address both of these problems:
1. The first patch makes sure the hypervisor doesn't accidentally clear
a guest's remote flush request
2. The rest of the patches prevent the race between hypervisor
acknowledging a remote flush request and guest issuing a new one.

Pull device mapper updates from Mike Snitzer:
- Fix DM core's potential for q->make_request_fn NULL pointer in the
unlikely case that a DM device is created without a DM table and then
accessed due to upper-layer userspace code or user error.
- Fix DM thin-provisioning's metadata_pre_commit_callback to not use
memory after it is free'd. Also refactor code to disallow changing
the thin-pool's data device once in use -- doing so guarantees smae
lifetime of pool's data device relative to the pool metadata.
- Fix DM space maps used by DM thinp and DM cache to avoid reuse of a
already used block. This race was identified with extremely heavy
snapshot use in the context of DM thin provisioning.
- Fix DM raid's table status relative to an active rebuild.
- Fix DM crypt to use GFP_NOIO rather than GFP_NOFS in call to
skcipher_request_alloc(). Also fix benbi IV constructor crash if used
in authenticated mode.
- Add DM crypt support for Elephant diffuser to allow for Bitlocker
compatibility.
- Fix DM verity target to not prefetch hash blocks for data that has
already been verified.
- Fix DM writecache's incorrect flush sequence during commit when in
SSD mode.
- Improve DM writecache's sequential write performance on SSDs.
- Add DM zoned target support for zone sizes smaller than 128MiB.
- Add DM multipath 'queue_if_no_path_timeout_secs' module param to
allow timeout if path isn't reinstated. This allows users a kernel
safety-net against IO hanging indefinitely, due to no active paths,
that has historically only been provided by multipathd userspace.

variable rename in dm-dust, and fix for a math error in comment for
DM thin metadata's ondisk format.

Pull openat2 support from Al Viro:
"This is the openat2() series from Aleksa Sarai.
I'm afraid that the rest of namei stuff will have to wait - it got
zero review the last time I'd posted #work.namei, and there had been a
leak in the posted series I'd caught only last weekend. I was going to
repost it on Monday, but the window opened and the odds of getting any
review during that... Oh, well.
Anyway, openat2 part should be ready; that _did_ get sane amount of
review and public testing, so here it comes"
From Aleksa's description of the series:
"For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown
flags are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road
to being added to openat(2).
Furthermore, the need for some sort of control over VFS's path
resolution (to avoid malicious paths resulting in inadvertent
breakouts) has been a very long-standing desire of many userspace
applications.
This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset
(which was a variant of David Drysdale's O_BENEATH patchset[4] which
was a spin-off of the Capsicum project[5]) with a few additions and
changes made based on the previous discussion within [6] as well as
others I felt were useful.
In line with the conclusions of the original discussion of
AT_NO_JUMPS, the flag has been split up into separate flags. However,
instead of being an openat(2) flag it is provided through a new
syscall openat2(2) which provides several other improvements to the
openat(2) interface (see the patch description for more details). The
following new LOOKUP_* flags are added:
LOOKUP_NO_XDEV:
Blocks all mountpoint crossings (upwards, downwards, or through
absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is
also blocked (though magic-link jumps on the same vfsmount are
permitted).
LOOKUP_NO_MAGICLINKS:
Blocks resolution through /proc/$pid/fd-style links. This is done
by blocking the usage of nd_jump_link() during resolution in a
filesystem. The term "magic-links" is used to match with the only
reference to these links in Documentation/, but I'm happy to change
the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
LOOKUP_BENEATH:
Disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed.
Conceptually this flag is to ensure you "stay below" a certain
point in the filesystem tree -- but this requires some additional
to protect against various races that would allow escape using
"..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done
as in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
LOOKUP_NO_SYMLINKS:
Does what it says on the tin. No symlink resolution is allowed at
all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this
can still be used with NOFOLLOW to open an fd for the symlink as
long as no parent path had a symlink component.
LOOKUP_IN_ROOT:
This is an extension of LOOKUP_BENEATH that, rather than blocking
attempts to move past the root, forces all such movements to be
scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that
chroot(2) is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to
cross magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container.
There is a long list of CVEs that could have bene mitigated by
having RESOLVE_THIS_ROOT (such as CVE-2017-1002101,
CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a
few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution.
It features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like
RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow
programs to be sure they don't hit DoSes though stale NFS handles)"

Pull IMA updates from Mimi Zohar:
"Two new features - measuring certificates and querying IMA for a file
hash - and three bug fixes:
- Measuring certificates is like the rest of IMA, based on policy,
but requires loading a custom policy. Certificates loaded onto a
keyring, for example during early boot, before a custom policy has
been loaded, are queued and only processed after loading the custom
policy.
- IMA calculates and caches files hashes. Other kernel subsystems,
and possibly kernel modules, are interested in accessing these
cached file hashes.
The bug fixes prevent classifying a file short read (e.g. shutdown) as
an invalid file signature, add a missing blank when displaying the
securityfs policy rules containing LSM labels, and, lastly, fix the
handling of the IMA policy information for unknown LSM labels"

and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI; some ioctls have been
extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers; the API
itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers; now
including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
RT1015 and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers"

Pull fscrypt updates from Eric Biggers:
- Extend the FS_IOC_ADD_ENCRYPTION_KEY ioctl to allow the raw key to be
provided via a keyring key.
- Prepare for the new dirhash method (SipHash of plaintext name) that
will be used by directories that are both encrypted and casefolded.
- Switch to a new format for "no-key names" that prepares for the new
dirhash method, and also fixes a longstanding bug where multiple
filenames could map to the same no-key name.
- Allow the crypto algorithms used by fscrypt to be built as loadable
modules when the fscrypt-capable filesystems are.
- Optimize fscrypt_zeroout_range().
- Various cleanups.
