UPSTREAM: sched/uclamp: Extend sched_setattr() to support utilization clamping
The SCHED_DEADLINE scheduling class provides an advanced and formal model to define tasks requirements that can translate into proper decisions for both task placements and frequencies selections. Other classes have a more simplified model based on the POSIX concept of priorities. Such a simple priority based model however does not allow to exploit most advanced features of the Linux scheduler like, for example, driving frequencies selection via the schedutil cpufreq governor. However, also for non SCHED_DEADLINE tasks, it's still interesting to define tasks properties to support scheduler decisions. Utilization clamping exposes to user-space a new set of per-task attributes the scheduler can use as hints about the expected/required utilization for a task. This allows to implement a "proactive" per-task frequency control policy, a more advanced policy than the current one based just on "passive" measured task utilization. For example, it's possible to boost interactive tasks (e.g. to get better performance) or cap background tasks (e.g. to be more energy/thermal efficient). Introduce a new API to set utilization clamping values for a specified task by extending sched_setattr(), a syscall which already allows to define task specific properties for different scheduling classes. A new pair of attributes allows to specify a minimum and maximum utilization the scheduler can consider for a task. Do that by validating the required clamp values before and then applying the required changes using _the_ same pattern already in use for __setscheduler(). This ensures that the task is re-enqueued with the new clamp values.

UPSTREAM: sched/core: Allow sched_setattr() to use the current policy
The sched_setattr() syscall mandates that a policy is always specified. This requires to always know which policy a task will have when attributes are configured and this makes it impossible to add more generic task attributes valid across different scheduling policies. Reading the policy before setting generic tasks attributes is racy since we cannot be sure it is not changed concurrently. Introduce the required support to change generic task attributes without affecting the current task policy. This is done by adding an attribute flag (SCHED_FLAG_KEEP_POLICY) to enforce the usage of the current policy. Add support for the SETPARAM_POLICY policy, which is already used by the sched_setparam() POSIX syscall, to the sched_setattr() non-POSIX syscall.

FROMLIST: fuse: Allow non-extending parallel direct writes
In general, as of now, in FUSE, direct writes on the same file are serialized over inode lock i.e we hold inode lock for the full duration of the write request. I could not found in fuse code a comment which clearly explains why this exclusive lock is taken for direct writes. Our guess is some USER space fuse implementations might be relying on this lock for seralization and also it protects for the issues arising due to file size assumption or write failures. This patch relaxes this exclusive lock in some cases of direct writes. With these changes, we allows non-extending parallel direct writes on the same file with the help of a flag called FOPEN_PARALLEL_WRITES. If this flag is set on the file (flag is passed from libfuse to fuse kernel as part of file open/create), we do not take exclusive lock instead use shared lock so that all non-extending writes can run in parallel. Best practise would be to enable parallel direct writes of all kinds including extending writes as well but we see some issues such as when one write completes and other fails, how we should truncate(if needed) the file if underlying file system does not support holes (For file systems which supports holes, there might be a possibility of enabling parallel writes for all cases). FUSE implementations which rely on this inode lock for serialisation can continue to do so and this is default behaviour i.e no parallel direct writes.

mm/mremap: add MREMAP_DONTUNMAP to mremap()
When remapping an anonymous, private mapping, if MREMAP_DONTUNMAP is set, the source mapping will not be removed. The remap operation will be performed as it would have been normally by moving over the page tables to the new mapping. The old vma will have any locked flags cleared, have no pagetables, and any userfaultfds that were watching that range will continue watching it. For a mapping that is shared or not anonymous, MREMAP_DONTUNMAP will cause the mremap() call to fail. Because MREMAP_DONTUNMAP always results in moving a VMA you MUST use the MREMAP_MAYMOVE flag, it's not possible to resize a VMA while also moving with MREMAP_DONTUNMAP so old_len must always be equal to the new_len otherwise it will return -EINVAL. We hope to use this in Chrome OS where with userfaultfd we could write an anonymous mapping to disk without having to STOP the process or worry about VMA permission changes. This feature also has a use case in Android, Lokesh Gidra has said that "As part of using userfaultfd for GC, We'll have to move the physical pages of the java heap to a separate location. For this purpose mremap will be used. Without the MREMAP_DONTUNMAP flag, when I mremap the java heap, its virtual mapping will be removed as well. Therefore, we'll require performing mmap immediately after. This is not only time consuming but also opens a time window where a native thread may call mmap and reserve the java heap's address range for its own usage. This flag solves the problem."

xfrm: enforce validity of offload input flags
commit 7c76ecd9c99b6e9a771d813ab1aa7fa428b3ade1 upstream.
struct xfrm_user_offload has flags variable that received user input,
but kernel didn't check if valid bits were provided. It caused a situation
where not sanitized input was forwarded directly to the drivers.
For example, XFRM_OFFLOAD_IPV6 define that was exposed, was used by
strongswan, but not implemented in the kernel at all.
As a solution, check and sanitize input flags to forward
XFRM_OFFLOAD_INBOUND to the drivers.

FROMLIST: fuse: Definitions and ioctl for passthrough
Expose the FUSE_PASSTHROUGH interface to user space and declare all the basic data structures and functions as the skeleton on top of which the FUSE passthrough functionality will be built. As part of this, introduce the new FUSE passthrough ioctl, which allows the FUSE daemon to specify a direct connection between a FUSE file and a lower file system file. Such ioctl requires user space to pass the file descriptor of one of its opened files through the fuse_passthrough_out data structure introduced in this patch. This structure includes extra fields for possible future extensions. Also, add the passthrough functions for the set-up and tear-down of the data structures and locks that will be used both when fuse_conns and fuse_files are created/deleted.

FROMLIST: fuse: 32-bit user space ioctl compat for fuse device
With a 64-bit kernel build the FUSE device cannot handle ioctl requests coming from 32-bit user space. This is due to the ioctl command translation that generates different command identifiers that thus cannot be used for direct comparisons without proper manipulation. Explicitly extract type and number from the ioctl command to enable 32-bit user space compatibility on 64-bit kernel builds.

fuse: return -ECONNABORTED on /dev/fuse read after abort
Currently the userspace has no way of knowing whether the fuse connection ended because of umount or abort via sysfs. It makes it hard for filesystems to free the mountpoint after abort without worrying about removing some new mount. The patch fixes it by returning different errors when userspace reads from /dev/fuse (-ENODEV for umount and -ECONNABORTED for abort). Add a new capability flag FUSE_ABORT_ERROR. If set and the connection is gone because of sysfs abort, reading from the device will return -ECONNABORTED.

fs: Add aio iopriority support
This is the per-I/O equivalent of the ioprio_set system call. When IOCB_FLAG_IOPRIO is set on the iocb aio_flags field, then we set the newly added kiocb ki_ioprio field to the value in the iocb aio_reqprio field. This patch depends on block: add ioprio_check_cap function.

serial: 8250: Define RX trigger levels for OxSemi 950 devices
[ Upstream commit d7aff291d069c4418285f3c8ee27b0ff67ce5998 ]
Oxford Semiconductor 950 serial port devices have a 128-byte FIFO and in
the enhanced (650) mode, which we select in `autoconfig_has_efr' with
the ECB bit set in the EFR register, they support the receive interrupt
trigger level selectable with FCR bits 7:6 from the set of 16, 32, 112,
120. This applies to the original OX16C950 discrete UART[1] as well as
950 cores embedded into more complex devices.
For these devices we set the default to 112, which sets an excessively
high level of 112 or 7/8 of the FIFO capacity, unlike with other port
types where we choose at most 1/2 of their respective FIFO capacities.
Additionally we don't make the trigger level configurable. Consequently
frequent input overruns happen with high bit rates where hardware flow
control cannot be used (e.g. terminal applications) even with otherwise
highly-performant systems.
Lower the default receive interrupt trigger level to 32 then, and make
it configurable. Document the trigger levels along with other port
types, including the set of 16, 32, 64, 112 for the transmit interrupt
as well[2].

binder: tell userspace to dump current backtrace when detected oneway spamming
When async binder buffer got exhausted, some normal oneway transactions will also be discarded and may cause system or application failures. By that time, the binder debug information we dump may not be relevant to the root cause. And this issue is difficult to debug if without the backtrace of the thread sending spam. This change will send BR_ONEWAY_SPAM_SUSPECT to userspace when oneway spamming is detected, request to dump current backtrace. Oneway spamming will be reported only once when exceeding the threshold (target process dips below 80% of its oneway space, and current process is responsible for either more than 50 transactions, or more than 50% of the oneway space). And the detection will restart when the async buffer has returned to a healthy state.

BACKPORT: binder: implement BINDER_FREEZE ioctl
Frozen tasks can't process binder transactions, so a way is required to inform transmitting ends of communication failures due to the frozen state of their receiving counterparts. Additionally, races are possible between transitions to frozen state and binder transactions enqueued to a specific process. Implement BINDER_FREEZE ioctl for user space to inform the binder driver about the intention to freeze or unfreeze a process. When the ioctl is called, block the caller until any pending binder transactions toward the target process are flushed. Return an error to transactions to processes marked as frozen.

BACKPORT: FROMGIT: net-tcp_bbr: BBRv2 for Linux TCP
BBR v2 is an enhacement to the BBR v1 algorithm. It's designed to aim for lower
queues, lower loss, and better Reno/CUBIC coexistence than BBR v1.
BBR v2 maintains the core of BBR v1: an explicit model of the network path that
is two-dimensional, adapting to estimate the (a) maximum available bandwidth
and (b) maximum safe volume of data a flow can keep in-flight in the
network. It mains the estimated BDP as a core guide for estimating an
appropriate level of in-flight data.
BBR v2 makes several key enhancements:
o Its bandwidth-probing time scale is adapted, within bounds, to allow improved
coexistence with Reno and CUBIC. The bandwidth-probing time scale is (a)
extended dynamically based on estimated BDP to improve coexistence with
Reno/CUBIC; (b) bounded by an interactive wall-clock time-scale to be more
scalable and responsive than Reno and CUBIC.
o Rather than being largely agnostic to loss and ECN marks, it explicitly uses
loss and (DCTCP-style) ECN signals to maintain its model.
o It aims for lower losses than v1 by adjusting its model to attempt to stay
within loss rate and ECN mark rate bounds (loss_thresh and ecn_thresh,
respectively).
o It adapts to loss/ECN signals even when the application is running out of
data ("application-limited"), in case the "application-limited" flow is also
"network-limited" (the bw and/or inflight available to this flow is lower than
previously estimated when the flow ran out of data).
o It has a three-part model: the model explicit three tracks operating points,
where an operating point is a tuple: (bandwidth, inflight). The three operating
points are:
o latest: the latest measurement from the current round trip
o upper bound: robust, optimistic, long-term upper bound
o lower bound: robust, conservative, short-term lower bound
These are stored in the following state variables:
o latest: bw_latest, inflight_latest
o lo: bw_lo, inflight_lo
o hi: bw_hi[2], inflight_hi
To gain intuition about the meaning of the three operating points, it
may help to consider the analogs in CUBIC, which has a somewhat
analogous three-part model used by its probing state machine:
BBR param CUBIC param
----------- -------------
latest ~ cwnd
lo ~ ssthresh
hi ~ last_max_cwnd
The analogy is only a loose one, though, since the BBR operating
points are calculated differently, and are 2-dimensional (bw,inflight)
rather than CUBIC's one-dimensional notion of operating point
(inflight).
o It uses the three-part model to adapt the magnitude of its bandwidth
to match the estimated space available in the buffer, rather than (as
in BBR v1) assuming that it was always acceptable to place 0.25*BDP in
the bottleneck buffer when probing (commodity datacenter switches
commonly do not have that much buffer for WAN flows). When BBR v2
estimates it hit a buffer limit during probing, its bandwidth probing
then starts gently in case little space is still available in the
buffer, and the accelerates, slowly at first and then rapidly if it
can grow inflight without seeing congestion signals. In such cases,
probing is bounded by inflight_hi + inflight_probe, where
inflight_probe grows as: [0, 1, 2, 4, 8, 16,...]. This allows BBR to
keep losses low and bounded if a bottleneck remains congested, while
rapidly/scalably utilizing free bandwidth when it becomes available.
o It has a slightly revised state machine, to achieve the goals above.
BBR_BW_PROBE_UP: pushes up inflight to probe for bw/vol
BBR_BW_PROBE_DOWN: drain excess inflight from the queue
BBR_BW_PROBE_CRUISE: use pipe, w/ headroom in queue/pipe
BBR_BW_PROBE_REFILL: try refill the pipe again to 100%, leaving queue empty
o The estimated BDP: BBR v2 continues to maintain an estimate of the
path's two-way propagation delay, by tracking a windowed min_rtt, and
coordinating (on an as-ndeeded basis) to try to expose the two-way
propagation delay by draining the bottleneck queue.
BBR v2 continues to use its min_rtt and (currently-applicable) bandwidth
estimate to estimate the current bandwidth-delay product. The estimated BDP
still provides one important guideline for bounding inflight data. However,
because any min-filtered RTT and max-filtered bw inherently tend to both
overestimate, the estimated BDP is often too high; in this case loss or ECN
marks can ensue, in which case BBR v2 adjusts inflight_hi and inflight_lo to
adapt its sending rate and inflight down to match the available capacity of the
path.
o Space: Note that ICSK_CA_PRIV_SIZE increased. This is because BBR v2
adds 17 more u32 to struct bbr. However, there are 11 u32 fields from
BBR v1 that we can remove after switching to BBR v2:
struct minmax bw; /* Max recent delivery rate in pkts/uS << 24 */
u32 rtt_cnt; /* count of packet-timed rounds elapsed */
...
packet_conservation:1, /* use packet conservation? */
...
lt_is_sampling:1, /* taking long-term ("LT") samples now? */
lt_rtt_cnt:7, /* round trips in long-term interval */
lt_use_bw:1; /* use lt_bw as our bw estimate? */
u32 lt_bw; /* LT est delivery rate in pkts/uS << 24 */
u32 lt_last_delivered; /* LT intvl start: tp->delivered */
u32 lt_last_stamp; /* LT intvl start: tp->delivered_mstamp */
u32 lt_last_lost; /* LT intvl start: tp->lost */
So ultimately BBR v2 uses 17-11 = 6 more u32 fields than v1.
o Code: BBR v2 reuses many pieces from BBR v1. But it omits the following
significant pieces:
o "packet conservation" (bbr_set_cwnd_to_recover_or_restore(),
bbr_can_grow_inflight())
o long-term bandwidth estimator ("policer mode")
The code layout tries to keep BBR v2 code near the bottom of the
file, so that v1-applicable code in the top does not accidentally
refer to v2 code.
o Docs:
See the following docs for more details and diagrams decsribing the BBR v2
algorithm:

o Internal notes:
For this upstream rebase, Neal started from:
git show 6f6734c1c3c4:net/ipv4/tcp_bbr.c > net/ipv4/tcp_bbr.c
then removed dev instrumentation (dynamic get/set for parameters)
and code that was only used by BBRv1

UPSTREAM: net: WireGuard secure network tunnel
WireGuard is a layer 3 secure networking tunnel made specifically for the kernel, that aims to be much simpler and easier to audit than IPsec. Extensive documentation and description of the protocol and considerations, along with formal proofs of the cryptography, are available at: * https://www.wireguard.com/ * https://www.wireguard.com/papers/wireguard.pdf This commit implements WireGuard as a simple network device driver, accessible in the usual RTNL way used by virtual network drivers. It makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of networking subsystem APIs. It has a somewhat novel multicore queueing system designed for maximum throughput and minimal latency of encryption operations, but it is implemented modestly using workqueues and NAPI. Configuration is done via generic Netlink, and following a review from the Netlink maintainer a year ago, several high profile userspace tools have already implemented the API. This commit also comes with several different tests, both in-kernel tests and out-of-kernel tests based on network namespaces, taking profit of the fact that sockets used by WireGuard intentionally stay in the namespace the WireGuard interface was originally created, exactly like the semantics of userspace tun devices. See wireguard.com/netns/ for pictures and examples. The source code is fairly short, but rather than combining everything into a single file, WireGuard is developed as cleanly separable files, making auditing and comprehension easier. Things are laid out as follows: * noise.[ch], cookie.[ch], messages.h: These implement the bulk of the cryptographic aspects of the protocol, and are mostly data-only in nature, taking in buffers of bytes and spitting out buffers of bytes. They also handle reference counting for their various shared pieces of data, like keys and key lists. * ratelimiter.[ch]: Used as an integral part of cookie.[ch] for ratelimiting certain types of cryptographic operations in accordance with particular WireGuard semantics. * allowedips.[ch], peerlookup.[ch]: The main lookup structures of WireGuard, the former being trie-like with particular semantics, an integral part of the design of the protocol, and the latter just being nice helper functions around the various hashtables we use. * device.[ch]: Implementation of functions for the netdevice and for rtnl, responsible for maintaining the life of a given interface and wiring it up to the rest of WireGuard. * peer.[ch]: Each interface has a list of peers, with helper functions available here for creation, destruction, and reference counting. * socket.[ch]: Implementation of functions related to udp_socket and the general set of kernel socket APIs, for sending and receiving ciphertext UDP packets, and taking care of WireGuard-specific sticky socket routing semantics for the automatic roaming. * netlink.[ch]: Userspace API entry point for configuring WireGuard peers and devices. The API has been implemented by several userspace tools and network management utility, and the WireGuard project distributes the basic wg(8) tool. * queueing.[ch]: Shared function on the rx and tx path for handling the various queues used in the multicore algorithms. * send.c: Handles encrypting outgoing packets in parallel on multiple cores, before sending them in order on a single core, via workqueues and ring buffers. Also handles sending handshake and cookie messages as part of the protocol, in parallel. * receive.c: Handles decrypting incoming packets in parallel on multiple cores, before passing them off in order to be ingested via the rest of the networking subsystem with GRO via the typical NAPI poll function. Also handles receiving handshake and cookie messages as part of the protocol, in parallel. * timers.[ch]: Uses the timer wheel to implement protocol particular event timeouts, and gives a set of very simple event-driven entry point functions for callers. * main.c, version.h: Initialization and deinitialization of the module. * selftest/*.h: Runtime unit tests for some of the most security sensitive functions. * tools/testing/selftests/wireguard/netns.sh: Aforementioned testing script using network namespaces. This commit aims to be as self-contained as possible, implementing WireGuard as a standalone module not needing much special handling or coordination from the network subsystem. I expect for future optimizations to the network stack to positively improve WireGuard, and vice-versa, but for the time being, this exists as intentionally standalone. We introduce a menu option for CONFIG_WIREGUARD, as well as providing a verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG. Signed-off-by: Jason A.

icmp: don't send out ICMP messages with a source address of 0.0.0.0
[ Upstream commit 321827477360934dc040e9d3c626bf1de6c3ab3c ]
When constructing ICMP response messages, the kernel will try to pick a
suitable source address for the outgoing packet. However, if no IPv4
addresses are configured on the system at all, this will fail and we end up
producing an ICMP message with a source address of 0.0.0.0. This can happen
on a box routing IPv4 traffic via v6 nexthops, for instance.
Since 0.0.0.0 is not generally routable on the internet, there's a good
chance that such ICMP messages will never make it back to the sender of the
original packet that the ICMP message was sent in response to. This, in
turn, can create connectivity and PMTUd problems for senders. Fortunately,
RFC7600 reserves a dummy address to be used as a source for ICMP
messages (192.0.0.8/32), so let's teach the kernel to substitute that
address as a last resort if the regular source address selection procedure
fails.
Below is a quick example reproducing this issue with network namespaces:
ip netns add ns0
ip l add type veth peer netns ns0
ip l set dev veth0 up
ip a add 10.0.0.1/24 dev veth0
ip a add fc00:dead:cafe:42::1/64 dev veth0
ip r add 10.1.0.0/24 via inet6 fc00:dead:cafe:42::2
ip -n ns0 l set dev veth0 up
ip -n ns0 a add fc00:dead:cafe:42::2/64 dev veth0
ip -n ns0 r add 10.0.0.0/24 via inet6 fc00:dead:cafe:42::1
ip netns exec ns0 sysctl -w net.ipv4.icmp_ratelimit=0
ip netns exec ns0 sysctl -w net.ipv4.ip_forward=1
tcpdump -tpni veth0 -c 2 icmp &
ping -w 1 10.1.0.1 > /dev/null
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
listening on veth0, link-type EN10MB (Ethernet), snapshot length 262144 bytes
IP 10.0.0.1 > 10.1.0.1: ICMP echo request, id 29, seq 1, length 64
IP 0.0.0.0 > 10.0.0.1: ICMP net 10.1.0.1 unreachable, length 92
2 packets captured
2 packets received by filter
0 packets dropped by kernel
With this patch the above capture changes to:
IP 10.0.0.1 > 10.1.0.1: ICMP echo request, id 31127, seq 1, length 64
IP 192.0.0.8 > 10.0.0.1: ICMP net 10.1.0.1 unreachable, length 92
