selftests/bpf: Fix issues in parse_num_list()
The function does not check that parsing_end is false after parsing argument. Thus, if the final part of the argument is something like '4-', which is invalid, parse_num_list() will discard it instead of returning -EINVAL. Before: $ ./test_progs -n 2,4- #2 atomic_bounds:OK Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED After: $ ./test_progs -n 2,4- Failed to parse test numbers.

selftests/bpf: Add urandom_read shared lib and USDTs
Extend urandom_read helper binary to include USDTs of 4 combinations: semaphore/semaphoreless (refcounted and non-refcounted) and based in executable or shared library. We also extend urandom_read with ability to report it's own PID to parent process and wait for parent process to ready itself up for tracing urandom_read. We utilize popen() and underlying pipe properties for proper signaling. Once urandom_read is ready, we add few tests to validate that libbpf's USDT attachment handles all the above combinations of semaphore (or lack of it) and static or shared library USDTs. Also, we validate that libbpf handles shared libraries both with PID filter and without one (i.e., -1 for PID argument). Having the shared library case tested with and without PID is important because internal logic differs on kernels that don't support BPF cookies. On such older kernels, attaching to USDTs in shared libraries without specifying concrete PID doesn't work in principle, because it's impossible to determine shared library's load address to derive absolute IPs for uprobe attachments. Without absolute IPs, it's impossible to perform correct look up of USDT spec based on uprobe's absolute IP (the only kind available from BPF at runtime). This is not the problem on newer kernels with BPF cookie as we don't need IP-to-ID lookup because BPF cookie value *is* spec ID. So having those two situations as separate subtests is good because libbpf CI is able to test latest selftests against old kernels (e.g., 4.9 and 5.5), so we'll be able to disable PID-less shared lib attachment for old kernels, but will still leave PID-specific one enabled to validate this legacy logic is working correctly.

selftests/bpf: Add basic USDT selftests
Add semaphore-based USDT to test_progs itself and write basic tests to valicate both auto-attachment and manual attachment logic, as well as BPF-side functionality. Also add subtests to validate that libbpf properly deduplicates USDT specs and handles spec overflow situations correctly, as well as proper "rollback" of partially-attached multi-spec USDT. BPF-side of selftest intentionally consists of two files to validate that usdt.bpf.h header can be included from multiple source code files that are subsequently linked into final BPF object file without causing any symbol duplication or other issues. We are validating that __weak maps and bpf_usdt_xxx() API functions defined in usdt.bpf.h do work as intended. USDT selftests utilize sys/sdt.h header that on Ubuntu systems comes from systemtap-sdt-devel package. But to simplify everyone's life, including CI but especially casual contributors to bpf/bpf-next that are trying to build selftests, I've checked in sys/sdt.h header from [0] directly. This way it will work on all architectures and distros without having to figure it out for every relevant combination and adding any extra implicit package dependencies.

selftests/bpf: Fix parsing of prog types in UAPI hdr for bpftool sync
The script for checking that various lists of types in bpftool remain in sync with the UAPI BPF header uses a regex to parse enum bpf_prog_type. If this enum contains a set of values different from the list of program types in bpftool, it complains. This script should have reported the addition, some time ago, of the new BPF_PROG_TYPE_SYSCALL, which was not reported to bpftool's program types list. It failed to do so, because it failed to parse that new type from the enum. This is because the new value, in the BPF header, has an explicative comment on the same line, and the regex does not support that. Let's update the script to support parsing enum values when they have comments on the same line.

libbpf: Add auto-attach for uprobes based on section name
Now that u[ret]probes can use name-based specification, it makes
sense to add support for auto-attach based on SEC() definition.
The format proposed is
SEC("u[ret]probe/binary:[raw_offset|[function_name[+offset]]")
For example, to trace malloc() in libc:
SEC("uprobe/libc.so.6:malloc")
...or to trace function foo2 in /usr/bin/foo:
SEC("uprobe//usr/bin/foo:foo2")
Auto-attach is done for all tasks (pid -1). prog can be an absolute
path or simply a program/library name; in the latter case, we use
PATH/LD_LIBRARY_PATH to resolve the full path, falling back to
standard locations (/usr/bin:/usr/sbin or /usr/lib64:/usr/lib) if
the file is not found via environment-variable specified locations.

Currently, when we run test_progs with just executable file name, for example 'PATH=. test_progs-no_alu32', cd_flavor_subdir() will not check if test_progs is running as a flavored test runner and switch into corresponding sub-directory.

selftests/bpf: Fix clang compilation errors
llvm upstream patch ([1]) added to issue warning for code like
void test() {
int j = 0;
for (int i = 0; i < 1000; i++)
j++;
return;
}
This triggered several errors in selftests/bpf build since
compilation flag -Werror is used.
...
test_lpm_map.c:212:15: error: variable 'n_matches' set but not used [-Werror,-Wunused-but-set-variable]
size_t i, j, n_matches, n_matches_after_delete, n_nodes, n_lookups;

...
prog_tests/get_stack_raw_tp.c:32:15: error: variable 'cnt' set but not used [-Werror,-Wunused-but-set-variable]
static __u64 cnt;
^
...
For test_lpm_map.c, 'n_matches'/'n_matches_after_delete' are changed to be volatile
in order to silent the warning. I didn't remove these two declarations since
they are referenced in a commented code which might be used by people in certain
cases. For get_stack_raw_tp.c, the variable 'cnt' is removed.

selftests: test_vxlan_under_vrf: Fix broken test case
The purpose of the last test case is to test VXLAN encapsulation and
decapsulation when the underlay lookup takes place in a non-default VRF.
This is achieved by enslaving the physical device of the tunnel to a
VRF.
The binding of the VXLAN UDP socket to the VRF happens when the VXLAN
device itself is opened, not when its physical device is opened. This
was also mentioned in the cited commit ("tests that moving the underlay
from a VRF to another works when down/up the VXLAN interface"), but the
test did something else.
Fix it by reopening the VXLAN device instead of its physical device.
Before:
# ./test_vxlan_under_vrf.sh
Checking HV connectivity [ OK ]
Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ]
Check VM connectivity through VXLAN (underlay in a VRF) [FAIL]
After:
# ./test_vxlan_under_vrf.sh
Checking HV connectivity [ OK ]
Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ]
Check VM connectivity through VXLAN (underlay in a VRF) [ OK ]

selftests: kselftest framework: provide "finished" helper
Instead of having each time that wants to use ksft_exit() have to figure out the internals of kselftest.h, add the helper ksft_finished() that makes sure the passes, xfails, and skips are equal to the test plan count.

selftest/vm: add helpers to detect PAGE_SIZE and PAGE_SHIFT
PAGE_SIZE is not 4096 in many configurations, particularly ppc64 uses 64K
pages in majority of cases.
Add helpers to detect PAGE_SIZE and PAGE_SHIFT dynamically.
Without this tests are broken w.r.t reading /proc/self/pagemap
if (pread(pagemap_fd, ent, sizeof(ent),
(uintptr_t)ptr >> (PAGE_SHIFT - 3)) != sizeof(ent))
err(2, "read pagemap");

Networking changes for 5.18.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout
the stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower
iTLB pressure and prevents identity mapping huge pages from
getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop
the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called
from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling
of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

- Preparation for the implementation of Intel IPI virtualization
- Fix some segment descriptor checks in the emulator
- Allow AMD AVIC support on systems with physical APIC ID above 255
- Better API to disable virtualization quirks
- Fixes and optimizations for the zapping of page tables:
- Zap roots in two passes, avoiding RCU read-side critical sections
that last too long for very large guests backed by 4 KiB SPTEs.
- Zap invalid and defunct roots asynchronously via concurrency-managed
work queue.
- Allowing yielding when zapping TDP MMU roots in response to the root's
last reference being put.
- Batch more TLB flushes with an RCU trick. Whoever frees the paging
structure now holds RCU as a proxy for all vCPUs running in the guest,
i.e. to prolongs the grace period on their behalf. It then kicks the
the vCPUs out of guest mode before doing rcu_read_unlock().
Generic:
- Introduce __vcalloc and use it for very large allocations that
need memcg accounting

asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

sound updates for 5.18
It's been a fairly calm development cycle. There are a few
last-minute ALSA core fixes, most notably for covering PCM ioctl
races, but the most of rest are device-specific changes.
Below are some highlights:
* ALSA core:
- Fixes for PCM ioctl races that may lead to UAF
- Fix for oversized allocations in PCM OSS layer
* ASoC:
- Start of moving SoF to support multiple IPC mechanisms
- Use of NHLT ACPI table to reduce the amount of quirking required for
Intel systems
- Preliminary works forthcoming Intel AVS driver for legacy Intel DSP
firmwares
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek

Tracing updates for 5.18:
- New user_events interface. User space can register an event with the kernel describing the format of the event. Then it will receive a byte in a page mapping that it can check against. A privileged task can then enable that event like any other event, which will change the mapped byte to true, telling the user space application to start writing the event to the tracing buffer. - Add new "ftrace_boot_snapshot" kernel command line parameter. When set, the tracing buffer will be saved in the snapshot buffer at boot up when the kernel hands things over to user space. This will keep the traces that happened at boot up available even if user space boot up has tracing as well. - Have TRACE_EVENT_ENUM() also update trace event field type descriptions. Thus if a static array defines its size with an enum, the user space trace event parsers can still know how to parse that array. - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the TRACE_EVENT() macro, but will attach to an existing tracepoint. This will make one tracepoint be able to trace different content and not be stuck at only what the original TRACE_EVENT() macro exports. - Fixes to tracing error logging. - Better saving of cmdlines to PIDs when tracing (use the wakeup events for mapping). -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYjiO3RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qhQzAQDtek5p80p/zkMGymm14wSH6qq0NdgN Kv7fTBwEewUa0gD/UCOVLw4Oj+JtHQhCa3sCGZopmRv0BT1+4UQANqosKQY= =Au08 -----END PGP SIGNATURE----- Merge tag 'trace-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - New user_events interface.

userfaultfd/selftests: fix uninitialized_var.cocci warning
Fix following coccicheck warning: tools/testing/selftests/vm/userfaultfd.c:556:23-24: WARNING this kind of initialization is deprecated `unsigned long page_nr = *(&page_nr)` has the same form of uninitialized_var() macro.

selftests: vm: add a hugetlb test case
Since the head vmemmap page frame associated with each HugeTLB page is reused, we should hide the PG_head flag of tail struct page from the user. Add a tese case to check whether it is work properly. The test steps are as follows. 1) alloc 2MB hugeTLB 2) get each page frame 3) apply those APIs in each page frame 4) Those APIs work completely the same as before. Reading the flags of a page by /proc/kpageflags is done in stable_page_flags(), which has invoked PageHead(), PageTail(), PageCompound() and compound_head(). If those APIs work properly, the head page must have 15 and 17 bits set. And tail pages must have 16 and 17 bits set but 15 bit unset. Those flags are checked in check_page_flags().

selftests, x86: fix how check_cc.sh is being invoked
The $(CC) variable used in Makefiles could contain several arguments
such as "ccache gcc". These need to be passed as a single string to
check_cc.sh, otherwise only the first argument will be used as the
compiler command. Without quotes, the $(CC) variable is passed as
distinct arguments which causes the script to fail to build trivial
programs.
Fix this by adding quotes around $(CC) when calling check_cc.sh to pass
the whole string as a single argument to the script even if it has
several words such as "ccache gcc".

selftests: memcg: test high limit for single entry allocation
Test the enforcement of memory.high limit for large amount of memory allocation within a single kernel entry. There are valid use-cases where the application can trigger large amount of memory allocation within a single syscall e.g. mlock() or mmap(MAP_POPULATE). Make sure memory.high limit enforcement works for such use-cases.

Changes in this cycle were:
- Cleanups for SCHED_DEADLINE
- Tracing updates/fixes
- CPU Accounting fixes
- First wave of changes to optimize the overhead of the scheduler build,
from the fast-headers tree - including placeholder *_api.h headers for
later header split-ups.
- Preempt-dynamic using static_branch() for ARM64
- Isolation housekeeping mask rework; preperatory for further changes
- NUMA-balancing: deal with CPU-less nodes
- NUMA-balancing: tune systems that have multiple LLC cache domains per node (eg. AMD)
- Updates to RSEQ UAPI in preparation for glibc usage
- Lots of RSEQ/selftests, for same
- Add Suren as PSI co-maintainer
