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.

Pull more block and io_uring updates from Jens Axboe:
"I wasn't expecting this to be so big, and if I was, I would have used
separate branches for this. Going forward I'll be doing separate
branches for the current tree, just like for the next kernel version
tree. In any case, this contains:
- Series from Christoph that fixes an inherent race condition with
zoned devices and revalidation.
- null_blk zone size fix (Damien)
- Fix for a regression in this merge window that caused busy spins by
sending empty disk uevents (Eric)
- Fix for a regression in this merge window for bfq stats (Hou)
- Fix for io_uring creds allocation failure handling (me)
- io_uring -ERESTARTSYS send/recvmsg fix (me)
- Series that fixes the need for applications to retain state across
async request punts for io_uring. This one is a bit larger than I
would have hoped, but I think it's important we get this fixed for
5.5.
- connect(2) improvement for io_uring, handling EINPROGRESS instead
of having applications needing to poll for it (me)
- Have io_uring use a hash for poll requests instead of an rbtree.
This turned out to work much better in practice, so I think we
should make the switch now. For some workloads, even with a fair
amount of cancellations, the insertion sort is just too expensive.
(me)
- Various little io_uring fixes (me, Jackie, Pavel, LimingWu)
- Fix for brd unaligned IO, and a warning for the future (Ming)
- Fix for a bio integrity data leak (Justin)
- bvec_iter_advance() improvement (Pavel)
- Xen blkback page unmap fix (SeongJae)
The major items in here are all well tested, and on the liburing side
we continue to add regression and feature test cases. We're up to 50
topic cases now, each with anywhere from 1 to more than 10 cases in
each"

kcov: remote coverage support
Patch series " kcov: collect coverage from usb and vhost", v3. This patchset extends kcov to allow collecting coverage from backgound kernel threads. This extension requires custom annotations for each of the places where coverage collection is desired. This patchset implements this for hub events in the USB subsystem and for vhost workers. See the first patch description for details about the kcov extension. The other two patches apply this kcov extension to USB and vhost. Examples of other subsystems that might potentially benefit from this when custom annotations are added (the list is based on process_one_work() callers for bugs recently reported by syzbot): 1. fs: writeback wb_workfn() worker, 2. net: addrconf_dad_work()/addrconf_verify_work() workers, 3. net: neigh_periodic_work() worker, 4. net/p9: p9_write_work()/p9_read_work() workers, 5. block: blk_mq_run_work_fn() worker. These patches have been used to enable coverage-guided USB fuzzing with syzkaller for the last few years, see the details here: https://github.com/google/syzkaller/blob/master/docs/linux/external_fuzzing_usb.md This patchset has been pushed to the public Linux kernel Gerrit instance: https://linux-review.googlesource.com/c/linux/kernel/git/torvalds/linux/+/1524 This patch (of 3): Add background thread coverage collection ability to kcov. With KCOV_ENABLE coverage is collected only for syscalls that are issued from the current process. With KCOV_REMOTE_ENABLE it's possible to collect coverage for arbitrary parts of the kernel code, provided that those parts are annotated with kcov_remote_start()/kcov_remote_stop(). This allows to collect coverage from two types of kernel background threads: the global ones, that are spawned during kernel boot in a limited number of instances (e.g. one USB hub_event() worker thread is spawned per USB HCD); and the local ones, that are spawned when a user interacts with some kernel interface (e.g. vhost workers). To enable collecting coverage from a global background thread, a unique global handle must be assigned and passed to the corresponding kcov_remote_start() call. Then a userspace process can pass a list of such handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field of the kcov_remote_arg struct. This will attach the used kcov device to the code sections, that are referenced by those handles. Since there might be many local background threads spawned from different userspace processes, we can't use a single global handle per annotation. Instead, the userspace process passes a non-zero handle through the common_handle field of the kcov_remote_arg struct. This common handle gets saved to the kcov_handle field in the current task_struct and needs to be passed to the newly spawned threads via custom annotations. Those threads should in turn be annotated with kcov_remote_start()/kcov_remote_stop(). Internally kcov stores handles as u64 integers. The top byte of a handle is used to denote the id of a subsystem that this handle belongs to, and the lower 4 bytes are used to denote the id of a thread instance within that subsystem. A reserved value 0 is used as a subsystem id for common handles as they don't belong to a particular subsystem. The bytes 4-7 are currently reserved and must be zero. In the future the number of bytes used for the subsystem or handle ids might be increased. When a particular userspace process collects coverage by via a common handle, kcov will collect coverage for each code section that is annotated to use the common handle obtained as kcov_handle from the current task_struct. However non common handles allow to collect coverage selectively from different subsystems.

Merge tag 'gpio-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace.
After clear input from the RaspberryPi and Beagle communities, it
has been established that prototyping, industrial automation and
make communities strongly need this feature, and as we want people
to use the character device, we have implemented the simple pull
up/down interface for GPIO lines.
This means we can specify that a (chip-specific) pull up/down
resistor can be enabled, but does not offer fine-grained control
such as cases where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out the
old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it in all
GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when cooperating with
the pin control subsystem and registering ranges as part of adding
a gpiolib driver and a gpio_irq_chip driver at the same time. This
is also deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained handler"

Pull y2038 cleanups from Arnd Bergmann:
"y2038 syscall implementation cleanups
This is a series of cleanups for the y2038 work, mostly intended for
namespace cleaning: the kernel defines the traditional time_t, timeval
and timespec types that often lead to y2038-unsafe code. Even though
the unsafe usage is mostly gone from the kernel, having the types and
associated functions around means that we can still grow new users,
and that we may be missing conversions to safe types that actually
matter.
There are still a number of driver specific patches needed to get the
last users of these types removed, those have been submitted to the
respective maintainers"

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann: "As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers.

"Highlights:
- Infrastructure for secure boot on some bare metal Power9 machines.
The firmware support is still in development, so the code here
won't actually activate secure boot on any existing systems.
- A change to xmon (our crash handler / pseudo-debugger) to restrict
it to read-only mode when the kernel is lockdown'ed, otherwise it's
trivial to drop into xmon and modify kernel data, such as the
lockdown state.
- Support for KASLR on 32-bit BookE machines (Freescale / NXP).
- Fixes for our flush_icache_range() and __kernel_sync_dicache()
(VDSO) to work with memory ranges >4GB.
- Some reworks of the pseries CMM (Cooperative Memory Management)
driver to make it behave more like other balloon drivers and enable
some cleanups of generic mm code.
- A series of fixes to our hardware breakpoint support to properly
handle unaligned watchpoint addresses.
Plus a bunch of other smaller improvements, fixes and cleanups.

Add support for reset of secure guest via a new ioctl KVM_PPC_SVM_OFF. This ioctl will be issued by QEMU during reset and includes the the following steps: - Release all device pages of the secure guest. - Ask UV to terminate the guest via UV_SVM_TERMINATE ucall - Unpin the VPA pages so that they can be migrated back to secure side when guest becomes secure again. This is required because pinned pages can't be migrated. - Reinit the partition scoped page tables After these steps, guest is ready to issue UV_ESM call once again to switch to secure mode.

io_uring: add support for IORING_OP_CONNECT
This allows an application to call connect() in an async fashion. Like other opcodes, we first try a non-blocking connect, then punt to async context if we have to. Note that we can still return -EINPROGRESS, and in that case the caller should use IORING_OP_POLL_ADD to do an async wait for completion of the connect request (just like for regular connect(2), except we can do it async here too).

Pull thread management updates from Christian Brauner: - A pidfd's fdinfo file currently contains the field "Pid:\t<pid>" where <pid> is the pid of the process in the pid namespace of the procfs instance the fdinfo file for the pidfd was opened in. The fdinfo file has now gained a new "NSpid:\t<ns-pid1>[\t<ns-pid2>[...]]" field which lists the pids of the process in all child pid namespaces provided the pid namespace of the procfs instance it is looked up under has an ancestoral relationship with the pid namespace of the process. If it does not 0 will be shown and no further pid namespaces will be listed. Tests included. (Christian Kellner) - If the process the pidfd references has already exited, print -1 for the Pid and NSpid fields in the pidfd's fdinfo file. Tests included. (me) - Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler that are not SIG_DFL or SIG_IGN at process creation time. This originated as a feature request from glibc to improve performance and elimate races in their posix_spawn() implementation. Tests included. (me) - Add support for choosing a specific pid for a process with clone3(). This is the feature which was part of the thread update for v5.4 but after a discussion at LPC in Lisbon we decided to delay it for one more cycle in order to make the interface more generic. This has now done. It is now possible to choose a specific pid in a whole pid namespaces (sub)hierarchy instead of just one pid namespace. In order to choose a specific pid the caller must have CAP_SYS_ADMIN in all owning user namespaces of the target pid namespaces. Tests included. (Adrian Reber) - Test improvements and extensions.

- new block group profiles: RAID1 with 3- and 4- copies
- RAID1 in btrfs has always 2 copies, now add support for 3 and 4
- this is an incompat feature (named RAID1C34)
- recommended use of RAID1C3 is replacement of RAID6 profile on
metadata, this brings a more reliable resiliency against 2
device loss/damage
- support for new checksums
- per-filesystem, set at mkfs time
- fast hash (crc32c successor): xxhash, 64bit digest
- strong hashes (both 256bit): sha256 (slower, FIPS), blake2b
(faster)
- the blake2b module goes via the crypto tree, btrfs.ko has a
soft dependency
- speed up lseek, don't take inode locks unnecessarily, this can
speed up parallel SEEK_CUR/SEEK_SET/SEEK_END by 80%
- send:
- allow clone operations within the same file
- limit maximum number of sent clone references to avoid slow
backref walking
- error message improvements: device scan prints process name and PID
Core changes:
- cleanups
- remove unique workqueue helpers, used to provide a way to avoid
deadlocks in the workqueue code, now done in a simpler way
- remove lots of indirect function calls in compression code
- extent IO tree code moved out of extent_io.c
- cleanup backup superblock handling at mount time
- transaction life cycle documentation and cleanups
- locking code cleanups, annotations and documentation
- add more cold, const, pure function attributes
- removal of unused or redundant struct members or variables
- new tree-checker sanity tests
- try to detect missing INODE_ITEM, cross-reference checks of
DIR_ITEM, DIR_INDEX, INODE_REF, and XATTR_* items
- remove own bio scheduling code (used to avoid checksum submissions
being stuck behind other IO), replaced by cgroup controller-based
code to allow better control and avoid priority inversions in cases
where the custom and cgroup scheduling disagreed

- avoid getting stuck during cyclic writebacks
- fix trimming of ranges crossing block group boundaries

Pull io_uring updates from Jens Axboe:
"A lot of stuff has been going on this cycle, with improving the
support for networked IO (and hence unbounded request completion
times) being one of the major themes. There's been a set of fixes done
this week, I'll send those out as well once we're certain we're fully
happy with them.
This contains:
- Unification of the "normal" submit path and the SQPOLL path (Pavel)
- Support for sparse (and bigger) file sets, and updating of those
file sets without needing to unregister/register again.
- Independently sized CQ ring, instead of just making it always 2x
the SQ ring size. This makes it more flexible for networked
applications.
- Support for overflowed CQ ring, never dropping events but providing
backpressure on submits.
- Add support for absolute timeouts, not just relative ones.
- Support for generic cancellations. This divorces io_uring from
workqueues as well, which additionally gets us one step closer to
generic async system call support.
- With cancellations, we can support grabbing the process file table
as well, just like we do mm context. This allows support for system
calls that create file descriptors, like accept4() support that's
built on top of that.
- Support for io_uring tracing (Dmitrii)
- Support for linked timeouts. These abort an operation if it isn't
completed by the time noted in the linke timeout.
- Speedup tracking of poll requests
- Various cleanups making the coder easier to follow (Jackie, Pavel,
Bob, YueHaibing, me)
- Update MAINTAINERS with new io_uring list"

net: sched: allow flower to match erspan options
This patch is to allow matching options in erspan.
The options can be described in the form:
VER:INDEX:DIR:HWID/VER:INDEX_MASK:DIR_MASK:HWID_MASK.
When ver is set to 1, index will be applied while dir
and hwid will be ignored, and when ver is set to 2,
dir and hwid will be used while index will be ignored.
Different from geneve, only one option can be set. And
also, geneve options, vxlan options or erspan options
can't be set at the same time.

net: sched: allow flower to match vxlan options
This patch is to allow matching gbp option in vxlan.
The options can be described in the form GBP/GBP_MASK,
where GBP is represented as a 32bit hexadecimal value.
Different from geneve, only one option can be set. And
also, geneve options and vxlan options can't be set at
the same time.
# ip link add name vxlan0 type vxlan dstport 0 external
# tc qdisc add dev vxlan0 ingress
# tc filter add dev vxlan0 protocol ip parent ffff: \
flower \
enc_src_ip 10.0.99.192 \
enc_dst_ip 10.0.99.193 \
enc_key_id 11 \
vxlan_opts 01020304/ffffffff \
ip_proto udp \
action mirred egress redirect dev eth0
v1->v2:
- add .strict_start_type for enc_opts_policy as Jakub noticed.
- use Duplicate instead of Wrong in err msg for extack as Jakub
suggested.

net: sched: add erspan option support to act_tunnel_key
This patch is to allow setting erspan options using the
act_tunnel_key action. Different from geneve options,
only one option can be set. And also, geneve options,
vxlan options or erspan options can't be set at the
same time.
Options are expressed as ver:index:dir:hwid, when ver
is set to 1, index will be applied while dir and hwid
will be ignored, and when ver is set to 2, dir and
hwid will be used while index will be ignored.
# ip link add name erspan1 type erspan external
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 protocol ip parent ffff: \
flower indev eth0 \
ip_proto udp \
action tunnel_key \
set src_ip 10.0.99.192 \
dst_ip 10.0.99.193 \
dst_port 6081 \
id 11 \
erspan_opts 1:2:0:0 \
action mirred egress redirect dev erspan1
v1->v2:
- do the validation when dst is not yet allocated as Jakub suggested.
- use Duplicate instead of Wrong in err msg for extack.

bpf: Emit audit messages upon successful prog load and unload
Allow for audit messages to be emitted upon BPF program load and unload for having a timeline of events. The load itself is in syscall context, so additional info about the process initiating the BPF prog creation can be logged and later directly correlated to the unload event. The only info really needed from BPF side is the globally unique prog ID where then audit user space tooling can query / dump all info needed about the specific BPF program right upon load event and enrich the record, thus these changes needed here can be kept small and non-intrusive to the core. Raw example output: # auditctl -D # auditctl -a always,exit -F arch=x86_64 -S bpf # ausearch --start recent -m 1334 [...] ---- time->Wed Nov 20 12:45:51 2019 type=PROCTITLE msg=audit(1574271951.590:8974): proctitle="./test_verifier" type=SYSCALL msg=audit(1574271951.590:8974): arch=c000003e syscall=321 success=yes exit=14 a0=5 a1=7ffe2d923e80 a2=78 a3=0 items=0 ppid=742 pid=949 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=2 comm="test_verifier" exe="/root/bpf-next/tools/testing/selftests/bpf/test_verifier" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) type=UNKNOWN[1334] msg=audit(1574271951.590:8974): auid=0 uid=0 gid=0 ses=2 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=949 comm="test_verifier" exe="/root/bpf-next/tools/testing/selftests/bpf/test_verifier" prog-id=3260 event=LOAD ---- time->Wed Nov 20 12:45:51 2019 type=UNKNOWN[1334] msg=audit(1574271951.590:8975): prog-id=3260 event=UNLOAD ---- [...] Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Jiri Olsa <jolsa@kernel.org> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20191120213816.8186-1-jolsa@kernel.org |

net: sched: pie: enable timestamp based delay calculation
RFC 8033 suggests an alternative approach to calculate the queue delay in PIE by using a timestamp on every enqueued packet. This patch adds an implementation of that approach and sets it as the default method to calculate queue delay. The previous method (based on Little's law) to calculate queue delay is set as optional.

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next:
1) Wildcard support for the net,iface set from Kristian Evensen.
2) Offload support for matching on the input interface.
3) Simplify matching on vlan header fields.
4) Add nft_payload_rebuild_vlan_hdr() function to rebuild the vlan
header from the vlan sk_buff metadata.
5) Pass extack to nft_flow_cls_offload_setup().
6) Add C-VLAN matching support.
7) Use time64_t in xt_time to fix y2038 overflow, from Arnd Bergmann.
8) Use time_t in nft_meta to fix y2038 overflow, also from Arnd.
9) Add flow_action_entry_next() helper function to flowtable offload
infrastructure.
10) Add IPv6 support to the flowtable offload infrastructure.
11) Support for input interface matching from postrouting,
from Phil Sutter.
12) Missing check for ndo callback in flowtable offload, from wenxu.
13) Remove conntrack parameter from flow_offload_fill_dir(), from wenxu.
14) Do not pass flow_rule object for rule removal, cookie is sufficient
to achieve this.
15) Release flow_rule object in case of error from the offload commit
path.
16) Undo offload ruleset updates if transaction fails.
17) Check for error when binding flowtable callbacks, from wenxu.
18) Always unbind flowtable callbacks when unregistering hooks.
