Clients that make heavy use of the cache get more of it, and those that use less have reduced cache usage. - Add a new DM_GET_TARGET_VERSION ioctl to allow userspace to query the version number of a DM target (even if the associated module isn't yet loaded). - Fix invalid memory access in DM zoned target. - Fix the max_discard_sectors limit advertised by the DM raid target; it was mistakenly storing the limit in bytes rather than sectors. - Small optimizations and cleanups in DM writecache target. - Various fixes and cleanups in DM core, DM raid1 and space map portion of DM persistent data library. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAl2D7ycTHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWp9QCACwTkVGzPGMCbAaCVlCACo8B5JyY4OO FNxucqUlt1MHKuBbzJd4XwNGlLg68xjMUKVPYPlgina7TaDl+wvlTbHchaJS8nak x1zyhDSywy0F9f6HHiXJi/vshmAfa0xnIM6fQXVPM346S6xf9u7hqOJQMCrdvY92 w4FhuW9nVt5xizo8iC/3LzoWbhrWncT7dyZUZtG3/tmglhkEK7QwctlgQxcD7tXg H1lhntQzHzpxQAVBefWWdw7ubuDd6XCHuQMaxRhyR++c62P3eKDR8ck9hhd3hZKv E481gtxcsjKuYLxwULjqFJZaNFitWFNMJ7gppQyKRqCzn2zlGAL6npl8 =m6zD -----END PGP SIGNATURE----- Merge tag 'for-5.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - crypto and DM crypt advances that allow the crypto API to reclaim implementation details that do not belong in DM crypt.

"This is the main pull request for 5.4-rc1 merge window. I don't think
there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the

Core:
- space handling:
- improved ticket reservations and other high level logic in
order to remove special cases
- factor flushing infrastructure and use it for different
contexts, allows to remove some special case handling
- reduce metadata reservation when only updating inodes
- reduce global block reserve minimum size (affects small
filesystems)

- fix memory leaks in extent IO tree
- catch all TRIM range
Fixes:
- fix ENOSPC errors, leading to transaction aborts, when cloning
extents
- several fixes for inode number cache (mount option inode_cache)
- fix potential soft lockups during send when traversing large trees
- fix unaligned access to space cache pages with SLUB debug on
(PowerPC)
Other:
- refactoring public/private functions, moving to new or more
appropriate files
- defines converted to enums
- error handling improvements
- more assertions and comments
- old code deletion"

fs-verity for 5.4
Please consider pulling fs-verity for 5.4.
fs-verity is a filesystem feature that provides Merkle tree based
hashing (similar to dm-verity) for individual readonly files, mainly for
the purpose of efficient authenticity verification.
This pull request includes:
(a) The fs/verity/ support layer and documentation.
(b) fs-verity support for ext4 and f2fs.
Compared to the original fs-verity patchset from last year, the UAPI to
enable fs-verity on a file has been greatly simplified. Lots of other
things were cleaned up too.
fs-verity is planned to be used by two different projects on Android;
most of the userspace code is in place already. Another userspace tool
("fsverity-utils"), and xfstests, are also available. e2fsprogs and
f2fs-tools already have fs-verity support. Other people have shown
interest in using fs-verity too.
I've tested this on ext4 and f2fs with xfstests, both the existing tests
and the new fs-verity tests. This has also been in linux-next since
July 30 with no reported issues except a couple minor ones I found
myself and folded in fixes for.
Ted and I will be co-maintaining fs-verity.

fscrypt update for 5.4
This is a large update to fs/crypto/ which includes:
- Add ioctls that add/remove encryption keys to/from a filesystem-level
keyring. These fix user-reported issues where e.g. an encrypted home
directory can break NetworkManager, sshd, Docker, etc. because they
don't get access to the needed keyring. These ioctls also provide a
way to lock encrypted directories that doesn't use the vm.drop_caches
sysctl, so is faster, more reliable, and doesn't always need root.
- Add a new encryption policy version ("v2") which switches to a more
standard, secure, and flexible key derivation function, and starts
verifying that the correct key was supplied before using it. The key
derivation improvement is needed for its own sake as well as for
ongoing feature work for which the current way is too inflexible.
Work is in progress to update both Android and the 'fscrypt' userspace
tool to use both these features. (Working patches are available and
just need to be reviewed+merged.) Chrome OS will likely use them too.
This has also been tested on ext4, f2fs, and ubifs with xfstests -- both
the existing encryption tests, and the new tests for this. This has
also been in linux-next since Aug 16 with no reported issues. I'm also
using an fscrypt v2-encrypted home directory on my personal desktop.

Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt
Pull fscrypt updates from Eric Biggers:
"This is a large update to fs/crypto/ which includes:
- Add ioctls that add/remove encryption keys to/from a
filesystem-level keyring.
These fix user-reported issues where e.g. an encrypted home
directory can break NetworkManager, sshd, Docker, etc. because they
don't get access to the needed keyring. These ioctls also provide a
way to lock encrypted directories that doesn't use the
vm.drop_caches sysctl, so is faster, more reliable, and doesn't
always need root.
- Add a new encryption policy version ("v2") which switches to a more
standard, secure, and flexible key derivation function, and starts
verifying that the correct key was supplied before using it.
The key derivation improvement is needed for its own sake as well
as for ongoing feature work for which the current way is too
inflexible.
Work is in progress to update both Android and the 'fscrypt' userspace
tool to use both these features. (Working patches are available and
just need to be reviewed+merged.) Chrome OS will likely use them too.
This has also been tested on ext4, f2fs, and ubifs with xfstests --
both the existing encryption tests, and the new tests for this. This
has also been in linux-next since Aug 16 with no reported issues. I'm
also using an fscrypt v2-encrypted home directory on my personal
desktop"

Char/Misc driver patches for 5.4-rc1
Here is the big char/misc driver pull request for 5.4-rc1.
As has been happening in previous releases, more and more individual
driver subsystem trees are ending up in here. Now if that is good or
bad I can't tell, but hopefully it makes your life easier as it's more
of an aggregation of trees together to one merge point for you.
Anyway, lots of stuff in here:
- habanalabs driver updates
- thunderbolt driver updates
- misc driver updates
- coresight and intel_th hwtracing driver updates
- fpga driver updates
- extcon driver updates
- some dma driver updates
- char driver updates
- android binder driver updates

- parport driver fixes
- pcmcia driver fix
- uio driver updates
- w1 driver updates

Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1.
Lots of churn here, with a few driver/filesystems moving out of staging
finally:
- erofs moved out of staging
- greybus core code moved out of staging
Along with that, a new filesytem has been added:
- extfat
to provide support for those devices requiring that filesystem (i.e.
transfer devices to/from windows systems or printers.)
Other than that, there a number of new IIO drivers, and lots and lots
and lots of staging driver cleanups and minor fixes as people continue
to dig into those for easy changes.
All of these have been in linux-next for a while with no reported

Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things.

a fair few headline features which I've noted both in the tag and also
in the merge commits when I pulled everything together.
The part I'm most pleased with is that we had 35 contributors this
time around, which feels like a big jump from the usual small group of
core arm64 arch developers. Hopefully they all enjoyed it so much that
they'll continue to contribute, but we'll see.
It's probably worth highlighting that we've pulled in a branch from
the risc-v folks which moves our CPU topology code out to where it can
be shared with others.

ethtool: implement Energy Detect Powerdown support via phy-tunable
The `phy_tunable_id` has been named `ETHTOOL_PHY_EDPD` since it looks like this feature is common across other PHYs (like EEE), and defining `ETHTOOL_PHY_ENERGY_DETECT_POWER_DOWN` seems too long. The way EDPD works, is that the RX block is put to a lower power mode, except for link-pulse detection circuits. The TX block is also put to low power mode, but the PHY wakes-up periodically to send link pulses, to avoid lock-ups in case the other side is also in EDPD mode. Currently, there are 2 PHY drivers that look like they could use this new PHY tunable feature: the `adin` && `micrel` PHYs. The ADIN's datasheet mentions that TX pulses are at intervals of 1 second default each, and they can be disabled. For the Micrel KSZ9031 PHY, the datasheet does not mention whether they can be disabled, but mentions that they can modified. The way this change is structured, is similar to the PHY tunable downshift control: * a `ETHTOOL_PHY_EDPD_DFLT_TX_MSECS` value is exposed to cover a default TX interval; some PHYs could specify a certain value that makes sense * `ETHTOOL_PHY_EDPD_NO_TX` would disable TX when EDPD is enabled * `ETHTOOL_PHY_EDPD_DISABLE` will disable EDPD As noted by the `ETHTOOL_PHY_EDPD_DFLT_TX_MSECS` the interval unit is 1 millisecond, which should cover a reasonable range of intervals: - from 1 millisecond, which does not sound like much of a power-saver - to ~65 seconds which is quite a lot to wait for a link to come up when plugging a cable Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: David S.

taprio: Add support for hardware offloading
This allows taprio to offload the schedule enforcement to capable network cards, resulting in more precise windows and less CPU usage. The gate mask acts on traffic classes (groups of queues of same priority), as specified in IEEE 802.1Q-2018, and following the existing taprio and mqprio semantics. It is up to the driver to perform conversion between tc and individual netdev queues if for some reason it needs to make that distinction. Full offload is requested from the network interface by specifying "flags 2" in the tc qdisc creation command, which in turn corresponds to the TCA_TAPRIO_ATTR_FLAG_FULL_OFFLOAD bit. The important detail here is the clockid which is implicitly /dev/ptpN for full offload, and hence not configurable. A reference counting API is added to support the use case where Ethernet drivers need to keep the taprio offload structure locally (i.e. they are a multi-port switch driver, and configuring a port depends on the settings of other ports as well). The refcount_t variable is kept in a private structure (__tc_taprio_qopt_offload) and not exposed to drivers. In the future, the private structure might also be expanded with a backpointer to taprio_sched *q, to implement the notification system described in the patch (of when admin became oper, or an error occurred, etc, so the offload can be monitored with 'tc qdisc show').

Pull pidfd/waitid updates from Christian Brauner:
"This contains two features and various tests.
First, it adds support for waiting on process through pidfds by adding
the P_PIDFD type to the waitid() syscall. This completes the basic
functionality of the pidfd api (cf. [1]). In the meantime we also have
a new adition to the userspace projects that make use of the pidfd
api. The qt project was nice enough to send a mail pointing out that
they have a pr up to switch to the pidfd api (cf. [2]).
Second, this tag contains an extension to the waitid() syscall to make
it possible to wait on the current process group in a race free manner
(even though the actual problem is very unlikely) by specifing 0
together with the P_PGID type. This extension traces back to a
discussion on the glibc development mailing list.
There are also a range of tests for the features above. Additionally,
the test-suite which detected the pidfd-polling race we fixed in [3]
is included in this tag"

tcp: Add TCP_INFO counter for packets received out-of-order
For receive-heavy cases on the server-side, we want to track the connection quality for individual client IPs. This counter, similar to the existing system-wide TCPOFOQueue counter in /proc/net/netstat, tracks out-of-order packet reception. By providing this counter in TCP_INFO, it will allow understanding to what degree receive-heavy sockets are experiencing out-of-order delivery and packet drops indicating congestion. Please note that this is similar to the counter in NetBSD TCP_INFO, and has the same name. Also note that we avoid increasing the size of the tcp_sock struct by taking advantage of a hole.

md: add feature flag MD_FEATURE_RAID0_LAYOUT
Due to a bug introduced in Linux 3.14 we cannot determine the correctly layout for a multi-zone RAID0 array - there are two possibilities. It is possible to tell the kernel which to chose using a module parameter, but this can be clumsy to use. It would be best if the choice were recorded in the metadata. So add a feature flag for this purpose. If it is set, then the 'layout' field of the superblock is used to determine which layout to use. If this flag is not set, then mddev->layout gets set to -1, which causes the module parameter to be required.

PTP: introduce new versions of IOCTLs
The current version of the IOCTL have a small problem which prevents us from extending the API by making use of reserved fields. In these new IOCTLs, we are now making sure that flags and rsv fields are zero which will allow us to extend the API in the future.

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next:
1) Fix error path of nf_tables_updobj(), from Dan Carpenter.
2) Move large structure away from stack in the nf_tables offload
infrastructure, from Arnd Bergmann.
3) Move indirect flow_block logic to nf_tables_offload.
4) Support for synproxy objects, from Fernando Fernandez Mancera.
5) Support for fwd and dup offload.
6) Add __nft_offload_get_chain() helper, this implicitly fixes missing
mutex and check for offload flags in the indirect block support,
patch from wenxu.
7) Remove rules on device unregistration, from wenxu. This includes
two preparation patches to reuse nft_flow_offload_chain() and
nft_flow_offload_rule().
Large batch from Jeremy Sowden to make a second pass to the
CONFIG_HEADER_TEST support and a bit of housekeeping:
8) Missing include guard in conntrack label header, from Jeremy Sowden.
9) A few coding style errors: trailing whitespace, incorrect indent in
Kconfig, and semicolons at the end of function definitions.
10) Remove unused ipt_init() and ip6t_init() declarations.
11) Inline xt_hashlimit, ebt_802_3 and xt_physdev headers. They are
only used once.
12) Update include directive in several netfilter files.
13) Remove unused include/net/netfilter/ipv6/nf_conntrack_icmpv6.h.
14) Move nf_ip6_ext_hdr() to include/linux/netfilter_ipv6.h
15) Move several synproxy structure definitions to nf_synproxy.h
16) Move nf_bridge_frag_data structure to include/linux/netfilter_bridge.h
17) Clean up static inline definitions in nf_conntrack_ecache.h.
18) Replace defined(CONFIG...) || defined(CONFIG...MODULE) with IS_ENABLED(CONFIG...).
19) Missing inline function conditional definitions based on Kconfig
preferences in synproxy and nf_conntrack_timeout.
20) Update br_nf_pre_routing_ipv6() definition.
21) Move conntrack code in linux/skbuff.h to nf_conntrack headers.
22) Several patches to remove superfluous CONFIG_NETFILTER and
CONFIG_NF_CONNTRACK checks in headers, coming from the initial batch
support for CONFIG_HEADER_TEST for netfilter.

devlink: add unknown 'fw_load_policy' value
Similar to the 'reset_dev_on_drv_probe' devlink parameter, it is useful to have an unknown value which can be used by drivers to report that the hardware value isn't recognized or is otherwise invalid instead of failing the operation. This is especially useful for u8/enum parameters.

KVM: x86: Return to userspace with internal error on unexpected exit reason
Receiving an unexpected exit reason from hardware should be considered as a severe bug in KVM. Therefore, instead of just injecting #UD to guest and ignore it, exit to userspace on internal error so that it could handle it properly (probably by terminating guest). In addition, prefer to use vcpu_unimpl() instead of WARN_ONCE() as handling unexpected exit reason should be a rare unexpected event (that was expected to never happen) and we prefer to print a message on it every time it occurs to guest. Furthermore, dump VMCS/VMCB to dmesg to assist diagnosing such cases.

btrfs: replace: BTRFS_DEV_REPLACE_ITEM_STATE_x defines should go
The BTRFS_DEV_REPLACE_ITEM_STATE_x defines, as shown in [1], are unused in both kernel and btrfs-progs (except for one instance of BTRFS_DEV_REPLACE_ITEM_STATE_NEVER_STARTED in kernel). [1] btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_FINISHED 2 btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_CANCELED 3 btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED 4 Further these define-values are different form its counterpart BTRFS_IOCTL_DEV_REPLACE_STATE_x series as shown in [2]. [2] btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_SUSPENDED 2 btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_FINISHED 3 btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_CANCELED 4 So this patch deletes the BTRFS_DEV_REPLACE_ITEM_STATE_x altogether, and one instance of BTRFS_DEV_REPLACE_ITEM_STATE_NEVER_STARTED is replaced with BTRFS_IOCTL_DEV_REPLACE_STATE_NEVER_STARTED in the kernel.

KVM: arm/arm64: vgic: Allow more than 256 vcpus for KVM_IRQ_LINE
While parts of the VGIC support a large number of vcpus (we bravely allow up to 512), other parts are more limited. One of these limits is visible in the KVM_IRQ_LINE ioctl, which only allows 256 vcpus to be signalled when using the CPU or PPI types. Unfortunately, we've cornered ourselves badly by allocating all the bits in the irq field. Since the irq_type subfield (8 bit wide) is currently only taking the values 0, 1 and 2 (and we have been careful not to allow anything else), let's reduce this field to only 4 bits, and allocate the remaining 4 bits to a vcpu2_index, which acts as a multiplier: vcpu_id = 256 * vcpu2_index + vcpu_index With that, and a new capability (KVM_CAP_ARM_IRQ_LINE_LAYOUT_2) allowing this to be discovered, it becomes possible to inject PPIs to up to 4096 vcpus. But please just don't. Whilst we're there, add a clarification about the use of KVM_IRQ_LINE on arm, which is not completely conditionned by KVM_CAP_IRQCHIP.

====================
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add the ability to use unaligned chunks in the AF_XDP umem. By
relaxing where the chunks can be placed, it allows to use an
arbitrary buffer size and place whenever there is a free
address in the umem. Helps more seamless DPDK AF_XDP driver
integration. Support for i40e, ixgbe and mlx5e, from Kevin and
Maxim.
2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
application can wake up the kernel for rx/tx processing which
avoids busy-spinning of the latter, useful when app and driver
is located on the same core. Support for i40e, ixgbe and mlx5e,
from Magnus and Maxim.
3) bpftool fixes for printf()-like functions so compiler can actually
enforce checks, bpftool build system improvements for custom output
directories, and addition of 'bpftool map freeze' command, from Quentin.
4) Support attaching/detaching XDP programs from 'bpftool net' command,
from Daniel.
5) Automatic xskmap cleanup when AF_XDP socket is released, and several
barrier/{read,write}_once fixes in AF_XDP code, from Björn.
6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
inclusion as well as libbpf versioning improvements, from Andrii.
7) Several new BPF kselftests for verifier precision tracking, from Alexei.
8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.
9) And more BPF kselftest improvements all over the place, from Stanislav.
10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub.
11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan.
12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni.
13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin.
14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar.

net_sched: act_police: add 2 new attributes to support police 64bit rate and peakrate
For high speed adapter like Mellanox CX-5 card, it can reach upto 100 Gbits per second bandwidth. Currently htb already supports 64bit rate in tc utility. However police action rate and peakrate are still limited to 32bit value (upto 32 Gbits per second). Add 2 new attributes TCA_POLICE_RATE64 and TCA_POLICE_RATE64 in kernel for 64bit support so that tc utility can use them for 64bit rate and peakrate value to break the 32bit limit, and still keep the backward binary compatibility.
