selftests/net: use MAP_FAILED instead of (void *)-1 in tcp_mmap
mmap() is documented to return MAP_FAILED on error, but tcp_mmap.c compares the return value against (void *)-1 and (unsigned char *)-1. Replace these with the standard MAP_FAILED macro for better readability and type safety.

selftests/net: Skip srv6_end_dt46_l3vpn_test if iproute2 too old
In case iproute2 is older than version 5.14.0, released ~Sept 1, 2021,
the End.DT46 support is not available and the host_vpn_tests test contained
in the srv6_end_dt46_l3vpn_test.sh file is failing in some kernel backports.
This is the result of those tests:
################################################################################
TEST SECTION: SRv6 VPN connectivity test among hosts in the same tenant
################################################################################

TEST: IPv4 Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200) [ FAIL ]
To amend this, check the current running iproute2 supports the required
feature and, if not, just skip the entire test to avoid a failure.

selftests: seg6: add test for post-encap SID route lookup
Add a selftest for the SEG6_IPTUNNEL_TABLE attribute, which selects the FIB table for the post-encap SID route lookup. This looks up the route for the first SID, the outer destination of the encapsulated packet. Two routers provide L3 VPN services over an IPv6 underlay. Each router uses a separate VRF per tenant, with default blackhole routes (IPv4 and IPv6) that drop unmatched traffic. Tenant traffic is encapsulated, then decapsulated with an End.DT46. The encap routes are installed in the tenant VRF, but the routes that match the first SIDs live in a separate underlay table (500). The "lookup 500" attribute points the lookup there rather than to the VRF. The test covers both the input path, where forwarded host traffic triggers encapsulation, and the output path, where a router originates traffic from its own loopback inside a VRF. With the "lookup" attribute, traffic reaches its destination on both paths. Without it, on the input path the lookup stays in the VRF and hits the blackhole, and on the output path it falls through to the main table, which has no matching route.

Merge branch 'big-tcp-for-udp-tunnels'
Alice Mikityanska says: ==================== BIG TCP for UDP tunnels This series is a follow-up to "BIG TCP without HBH in IPv6", and it adds support for BIG TCP IPv4/IPv6 workloads in vxlan and geneve. Now that IPv6 BIG TCP doesn't require stripping the HBH in all various combinations in tunneled traffic, adding BIG TCP becomes feasible. Patch 01 adds accessors for the length field in the UDP header, as suggested by Paolo in review. The usage of udp_set_len is then added in the following patches that start using length=0 in BIG TCP UDP packets. Patches 02-04 close the gaps that prevent BIG TCP packets from going through UDP tunnel code. Patch 05 validates packets in udp_gro_receive to exclude packets with length=0 from GRO aggregation. Patch 06 is for proper formatting in tcpdump (set UDP len to 0 rather than a trimmed value on overflow). Patches 07-08 bump up tso_max_size for VXLAN and GENEVE. Patch 09 adds selftests. ====================$ Link: https://patch.msgid.link/20260710134242.216538-1-alice.kernel@fastmail.im Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

selftests: net: Add a test for BIG TCP in UDP tunnels
The test sets up VXLAN and GENEVE tunnels over IPv4 and IPv6 and runs IPv4 and IPv6 traffic through them with BIG TCP enabled. It checks that a non-negligible amount of big aggregated packets are seen by setting up iptables counters. Check the number of packets on both TX and RX sides to verify that GSO packets are valid and not dropped. Capture on the lower netdev (veth), when checksum offload is on, to verify that encapsulated BIG TCP packets can get to their destination. In the test with TX checksum offload off, software GSO splits aggregated VXLAN packets before passing them to veth, so capture inside the tunnel instead to check that the big packets are not dropped. Check that the amount of SACKs is negligible. On unsupported kernels, some amount of broken GSO packets bigger than 65536 bytes can be produced in VXLAN tunnels, but they don't reach the destination. Seeing TCP SACKs is a sign that such packets could have been dropped (in such cases, the amount of SACKs is a few times bigger than the number of attempts to send BIG TCP packets).

selftests/net/openvswitch: add ICMPv6 echo type match test
Register OVS_KEY_ATTR_ICMPV6 in the flow key parser so that
icmpv6(type=...) can be used in flow specifications. Without this
registration the parser silently drops the token and the kernel
rejects the flow with EINVAL because the expected ICMPv6 key
attribute is missing.
While here, add convert_int() to the ovs_key_ipv6 and ovs_key_icmp
fields_map entries so that specifying a field value produces the
correct wildcard mask. The IPv6 flow label uses convert_int(20) to
produce a 20-bit mask (0x000FFFFF), matching the kernel constraint in
flow_netlink.c that rejects masks with bits 20-31 set; byte-wide
fields use convert_int(8). The ipv4 counterpart already does this via
convert_int(); the ipv6 and icmp classes were simply missing the fifth
tuple element. Existing callers that pass empty parentheses are
unaffected because convert_int("") returns (0, 0).
Add test_icmpv6 exercising the ICMPv6 echo flow key. The test uses
static neighbour entries with nud permanent to prevent racy NDP, then
verifies in three steps: install icmpv6(type=128) and
icmpv6(type=129) flows and confirm ping works, remove the flows and
confirm ping fails, reinstall and confirm recovery.

selftests: net: add FOU multicast encapsulation resubmit test
Add a selftest to verify that FOU-encapsulated packets addressed to a multicast destination are correctly resubmitted to the inner protocol handler (GRE) via the UDP multicast delivery path. Both IPv4 and IPv6 paths are tested. The test creates two network namespaces connected by a veth pair with a FOU/GRETAP (IPv4) and FOU/ip6gretap (IPv6) tunnel using multicast remote addresses (239.0.0.1 and ff0e::1). Ping is sent through each tunnel and received packets are counted on the receiver's tunnel interface. The veth pair is created directly inside the namespaces to avoid possible name collisions with devices in the root namespace. Static neighbor entries are configured on the sender because ARP/ND replies from the receiver cannot traverse the unidirectional multicast tunnel back to the sender. The early demux optimization (net.ipv4.ip_early_demux, which controls both IPv4 and IPv6) is disabled on the receiver to force packets through __udp4_lib_mcast_deliver() / __udp6_lib_mcast_deliver(), which is the code path being tested.

selftests: netconsole: only restore MAC when it changed on resume
The "mac" bind mode reactivation downs the interface, restores the saved
MAC and renames it to trigger a target resume. This assumes the recreated
interface comes back with a different MAC, which is true under
MACAddressPolicy=none (as on the Netdev CI) but not when MACs are
persistent. In the persistent case netconsole resumes the target on its
own, and the down/restore/rename flow instead drops it and fails the test.
Guard the block on the MAC having actually changed so the test passes
under both policies.

KVM x86 fixes for 7.2-rcN
- Fix a bug where KVM will trigger a UAF if updating IOMMU IRTEs fails when
registering an IRQ-bypass producer.
- Ignore pending PV EOI instead of BUG()ing the host if the feature was
disabled by the guest.
- Fix nVMX bugs where KVM would run L1 with an L1-controlled CR3 after a
failed "late" consistency check when KVM is NOT using EPT.
- Disallow intra-host migration/mirroring of SNP VMs as KVM doesn't yet
support moving/mirroring SNP state.
- Fix a TOCTOU bug in KVM's handling of the "trusted" CPUID for TDX guests.
- Fix a NULL pointer deref in trace_kvm_inj_exception() where a change to the
core infrastructure missed KVM's unique (ab)use of __print_symbolic().

RISC-V updates for v7.2-rc3
- Avoid a null pointer deference in machine_kexec_prepare() that the
IMA subsystem can trigger
- Bypass libc in part of the ptrace_v_not_enabled kselftest to avoid
noise from child atfork handlers that libc might run
- Include Kconfig support for UltraRISC SoCs, already referenced by
some device drivers; and enable it in our defconfig
- Fix the build of the rseq kselftest for RISC-V by borrowing a
technique from the KVM and S390 kselftests that includes
arch-specific header files from tools/arch/<arch>/include
- Fix some memory leaks in the RISC-V vector ptrace kselftests

"The most notable change involves the rseq kselftest common Makefile
(as it is not RISC-V-specific). The basic approach in the patch
appears similar to one used in the KVM and S390 selftests (grep for
LINUX_TOOL_ARCH_INCLUDE and SUBARCH), and the rseq kselftests pass a
quick build test on x86 after this.

tracing fixes for 7.2:
- Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path. - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size. This is because archs with that config set will always use the "big event meta header" as that is 8 bytes keeping the payload 8 bytes aligned, even when a 4 byte header could hold the size of the event. But ring_buffer_event_length() doesn't take this into account and only subtracts 4 bytes for the meta header in the length when it should have subtracted 8 bytes. - Have osnoise wait for a full rcu synchronization on unregister osnoise_unregister_instance() used to call synchronize_rcu() before freeing its copy of the instance but was switched to kfree_rcu(). The osniose tracer has code that traverses the instances that it uses, and inst is just a pointer to that instance. By using kfree_rcu() instead of synchronize_rcu(), the instance that the inst pointer is pointing to can be freed while the osnoise code is still referencing it. That is, a rmdir on an instance first unregisters the tracer. When the unregister finishes, the rmdir expects that the tracer is finished with the instance that it is using. By putting back the synchronize_rcu() in osnoise_unregister_instance() the unregistering of osnoise will now return when all the users of the instance have finished. - Remove an unused setting of "ret" in tracing_set_tracer() - Fix ring_buffer_read_page() copying events The commit that changed ring_buffer_read_page() to show dropped events from the buffer itself, split the "commit" variable between the commit value (with flags) and "size" that holds the size of the sub-buffer. A cut and paste error changed the test of the reading from checking the size of the buffer to the size of the event causing reads to only read one event at a time. - Make tracepoint_printk a static variable When the tracing sysctl knobs were move from sysctl.c to trace.c, the variable tracepoint_printk no longer needed to be global. Make it static. - Fix some typos - Fix NULL pointer dereference in func_set_flag() The flags update of the function tracer first checks if the value of the flag is the same and exits if they are, and then it checks if the current tracer is the function tracer and exits if it isn't. The problem is that these checks need to be in a reversed order, as if the tracer isn't the function tracer, then the flag being checked may not exist. Reverse the order of these checks. - Fix ufs core trace events to not dereference a pointer in TP_printk() The TP_printk() part of the TRACE_EVENT() macro is called when the user reads the "trace" file. This can be seconds, minutes, hours, days, weeks, and even months after the data was recorded into the ring buffer. Thus, saving a pointer to an object into the ring buffer and then dereferencing it from TP_printk() can cause harm as the object the pointer is pointing to may no longer exist. Fix all the trace events in ufs core to save the device name in the ring buffer instead of dereferencing the device descriptor from TP_printk(). - Prevent out-of-bound reads in glob matching of trace events The filter logic of events allows simple glob logic to add wild cards to filter on strings. But some events have fields that may not have a terminating 'nul' character. This may cause the glob matching to go beyond the string. Change the logic to always pass in the length of the field that is being matched. - Add no-rcu-check version of trace_##event##_enabled() The trace_##event##_enabled() usually wraps trace events to do extra work that is only needed when the trace event is enabled. But this can hide events that are placed in locations where RCU is not watching, and can make lockdep not see these bugs when the event is not enabled. The trace_##event##_enabled() was updated to always test to make sure RCU is watching to catch locations that may call events without RCU being active. This caused a false positive for the irq_disabled() and related events. As that use trace_irq_disabled_enabled() to force RCU to be watching when the event is enabled via the ct_irq_enter() function, calls the event, and then calls ct_irq_exit() to put RCU back to its original state. The trace_irq_disabled_enabled() should not trigger a warning when RCU is not watching because the code within its block handles the case properly. Make a __trace_##event##_enabled() version for this event to use that doesn't check RCU is watching as it handles the case when it isn't. - Fix use-after-free in user_event_mm_dup() When the enabler is removed from the link list, it is freed immediately. But it is protected via RCU and needs to be freed after an RCU grace period. Use queue_rcu_work() so that the event_mutex can also be taken as user_event_put() takes the mutex on the last reference is released. - Free type string in error path of parse_synth_field() There's an error path in parse_synth_field() where the allocated type string is not freed. - Add selftest that tests deferred event teardown - Fix leak in error path of trace_remote_alloc_buffer() If page allocation fails, the desc->nr_cpus is not incremented for the current CPU and the allocations done for it are not freed. - Fix allocation length in trace_remote_alloc_buffer() The logic to calculate the struct_len was doing a double count and setting the value too large. Calculate the size upfront to fix the error and simplify the logic. - Fix sparse CPU masks in ring_buffer_desc() If there are sparse CPUs (gaps in the numbering), the ring_buffer_desc() will fail as it tests the CPU number against the number of CPUs that are used. -----BEGIN PGP SIGNATURE----- iQJIBAABCgAyFiEEXtmkj8VMCiLR0IBM68Js21pW3nMFAmpTv/cUHHJvc3RlZHRA Z29vZG1pcy5vcmcACgkQ68Js21pW3nN80w/9HEbliUUrJVNw8QCY8BmeBEzfCRhZ 2CeDzTg+UrLMb2BtqUhA9EjQnRPawe8mPxAfpZ750SdFnCkRhbfNwYmKar3M/8iW y2Bhsvd3Hz6nRiHvKhG/1RkflgKOWLYf/TQSByKlakYLV8t4uffa0fe0N0zcnikK XPGrhrTeRDJ7s94vb1u7p7mSSp2iy4ZhfXbagk966X3I4zvseIYNn5IIzyM3IIPT M7mE60SxvgSRz0QqTJqihmqjXYSeNOQ2iU18wnvp4QfcT0IVuLKm027JnK/YpjWS ZasMNGzO1kp5uo6hkXLrMlT3LjaNEMFTGogs1m9o9auhbMf443LK8GtZ1m1rwnTG cXn1PocBevQIaXWPbnxMrSwIuN7YMUqjgX6SCxbXpDxSSuE5i/x1VmE08CjxnSm6 TdAdom9bE44FvMgaAz9+KhIUgm013c2rFDNiFroYtfkma5FqpfnfglA4/TkJvexY e2L75cR3lrDEDiXXMQDndmvxNMhppwNlAH3mOZLiaCmGyFQFHhgAaG250K2Y6a5K HtIfJkT6RQ3rWifV0E0+zlyRiOrvVCCA8WwNArWb1dTWrVU86Hr7q58jAq9p0Yrz FnhpjdE3eWoUHZ5f28AMR2k5lMG3o6mOGT55JyUVCLw+rPSG5358UIg2xZiEo22k RFlT26FFHbMW50Y= =+//w -----END PGP SIGNATURE----- Merge tag 'trace-v7.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size.

selftests/tracing: Have trigger-hist-poll.tc use sched_process_exit
Currently trigger-hist-poll.tc uses sched_process_free to test the polling of the histogram file. The way it does that is to run sleep, then execute the poll.c code that polls on the sched_process_free for up to 4 seconds to test that when sleep triggers the sched_process_free trace event, it will update the histogram and wake the poll.c code up. The issue is that sched_process_free trace event is called by delayed_put_task_struct() which is called after a RCU grace period has ended. If CONFIG_RCU_LAZY is enabled, RCU callbacks are batched together and do not execute right away. This causes the delayed_put_task_struct() to be called after the poll.c function finishes and it will report an error that it did not wake up on the event. That's because the event didn't trigger during its wait time. Use sched_process_exit instead, which is called when a process exits and doesn't depend on RCU callbacks that may be delayed.

selftests/landlock: Fix screwed up pointers in the scoped_signal_test
The scoped_signal_test uses pthread_join(..., (void **)&ret)) in
a couple of places, i.e. the return value of the thread is stored
in the shape of a "void *" into the memory location of &ret.
Pointers are 64-bit on modern computers, but the ret variable is
declared as a simple "enum thread_return" which is only 32 bits.
So the pthread_join() will overflow the ret variable by 4 byte.
The problem is very visible on big endian systems like s390x
where the test is failing: The least significant byte that carries
the return code of the thread is not written into the ret variable
here, but somewhere else in the stack frame, so the comparison
for the right return code is failing here.
Fix it by getting rid of the enum and defining the THREAD_* constants
and "ret" variables as proper "void *" pointers. This way we can
also get rid of some ugly (void *) castings in a couple of spots.

tools/sched_ext: scx - Fix cmask_subset(), cmask_equal() and cmask_weight()
cmask_equal(), cmask_weight() and cmask_subset() bounded their word walks
with CMASK_NR_WORDS(nr_cids), which pads by one word and can't tell the last
word in use without @base. The walks could thus cover a slack word past the
active range, which cmask_reframe() leaves non-zero: a stale bit there gave
cmask_equal() a spurious mismatch, cmask_weight() an inflated count, and
cmask_subset() a spurious violation. cmask_subset() could also read
@b->bits[] one word past its allocation (within the arena's fault-recovered
range, so harmless), and deviated from the kernel scx_cmask_subset() by
failing any @a range that doesn't nest inside @b's even when the overhanging
bits are all clear.
Bound the cmask_equal() and cmask_weight() walks by the words the range
actually spans, with early returns for empty ranges. Rewrite cmask_subset()
to match the kernel semantics: scan @a's overhangs for set bits with
cmask_next_set() and walk the words of the range intersection.
cmask_subset() moves below cmask_next_set(), which it now uses. Padding bits
don't need masking as every cmask helper keeps them clear.

selftests/net: fix EVP_MD_CTX leak in tcp_mmap
In tcp_mmap.c, both child_thread() and main() allocate an EVP_MD_CTX
via EVP_MD_CTX_new() when integrity checking is enabled, but neither
function releases the context. child_thread() misses the free in its
common cleanup block, and main() returns without freeing the context.
This results in a SHA256 context leak on every run that uses the
‑i (integrity) option. Add the missing EVP_MD_CTX_free() calls to
the appropriate cleanup paths to fix the leak.

selftests/sched_ext: Verify nohz_full tick behavior
Finite-slice EXT tasks need the periodic scheduler tick to expire their slices even when nohz_full is enabled. Add a regression test that selects a nohz_full CPU and exercises both infinite-to-finite and finite-to-finite slice transitions across an idle interval. For each finite task, verify that its ops.tick() callback is invoked. Skip the test when an allowed nohz_full CPU and a separate housekeeping CPU are not available.

selftests/rseq: Fix a building error for riscv arch
RISC-V rseq selftests include asm/fence.h from tools/arch/riscv,
but the rseq Makefile only adds tools/include in the CFLAGS, this
results in the building failure both for native and cross build:
In file included from rseq.h:131,
from rseq.c:37:
rseq-riscv.h:11:10: fatal error: asm/fence.h: No such file or directory
To fix it, add the matching tools/arch/$(ARCH)/include path in the
CFLAGS and derive ARCH from SUBARCH for standalone native builds where
ARCH is not set.

selftests/user_events: Wait for deferred event teardown after unregister
Unregistering a user event now defers the drop of the enabler's event
reference (and the freeing of the enabler) past an RCU grace period. As a
result DIAG_IOCSDEL can transiently fail with -EBUSY while that last
reference is still being dropped, where it previously succeeded
immediately.
Two tests assumed the delete takes effect the instant the unregister
returns:
- abi_test "flags" deletes the event right after disabling it.
- perf_test's fixture teardown clear() deletes __test_event before the
next test registers the same name; a stale event makes the following
registration fail with -EADDRINUSE.
Retry the delete until it succeeds (or the event is already gone) with a
bounded wait, matching the existing wait_for_delete() idiom in the same
suite, so the tests are robust to the deferred teardown.

usbip: tools: support SuperSpeedPlus devices
USB devices running at SuperSpeedPlus report "10000" or "20000" in
their sysfs speed attribute. usbip currently maps only "5000" to
USB_SPEED_SUPER, so a SuperSpeedPlus device is imported as
USB_SPEED_UNKNOWN.
The attach request is then rejected by vhci_hcd:
vhci_hcd: Failed attach request for unsupported USB speed: UNKNOWN
Map the SuperSpeedPlus sysfs speed values to USB_SPEED_SUPER_PLUS, use
the SuperSpeed VHCI hub for SuperSpeedPlus devices, and recognize the
gadget current_speed string used by the kernel.

selftests: drv-net: xdp: run with both IP versions
Parameterize test cases by IP version using @ksft_variants. Set the environment's IP version at the start of each case using a new local helper, which also handles restoring the original value via defer(). The last case is left unparameterized because it does not send traffic or exercise IP-version-specific code. While here, fix an int vs str comparison bug `if cfg.addr_ipver == 4`.

selftests/net/openvswitch: add output truncation test
Add test_trunc exercising the OVS_ACTION_ATTR_TRUNC action. The test verifies truncation limits in four steps: reject trunc(1) and trunc(13) which are below ETH_HLEN, confirm normal forwarding works, apply trunc(14) which truncates packets to the Ethernet header and verify ping fails, then restore normal forwarding and verify recovery. The kernel requires max_len >= ETH_HLEN (14 bytes). trunc(14) sets OVS_CB(skb)->cutlen so pskb_trim strips the IP payload at output time; the receiver drops the runt frame and no echo reply is generated.
