selftests: mptcp: sockopt: fix error messages
This patch fixes several issues in the error reporting of the MPTCP sockopt
selftest:
1. Fix diff not printed: The error messages for counter mismatches had
the actual difference ('diff') as argument, but it was missing in the
format string. Displaying it makes the debugging easier.
2. Fix variable usage: The error check for 'mptcpi_bytes_acked' incorrectly
used 'ret2' (sent bytes) for both the expected value and the difference
calculation. It now correctly uses 'ret' (received bytes), which is the
expected value for bytes_acked.
3. Fix off-by-one in diff: The calculation for the 'mptcpi_rcv_delta' diff
was 's.mptcpi_rcv_delta - ret', which is off-by-one. It has been
corrected to 's.mptcpi_rcv_delta - (ret + 1)' to match the expected
value in the condition above it.

The previous commit adds the MPTCP_PM_EV_FLAG_DENY_JOIN_ID0 flag. Make
sure it is correctly announced by the other peer when it has been

pm_nl_ctl will now display 'deny_join_id0:1' when monitoring the events,
and when this flag was set by the other peer.
The 'Fixes' tag here below is the same as the one from the previous

selftests: mptcp: print trailing bytes with od
This is better than printing random bytes in the terminal. Note that Jakub suggested 'hexdump', but Mat found out this tool is not often installed by default. 'od' can do a similar job, and it is in the POSIX specs and available in coreutils, so it should be on more systems. While at it, display a few more bytes, just to fill in the two lines. And no need to display the 3rd only line showing the next number of bytes: 0000040.

selftests: mptcp: avoid spurious errors on TCP disconnect
The disconnect test-case, with 'plain' TCP sockets generates spurious errors, e.g. 07 ns1 TCP -> ns1 (dead:beef:1::1:10006) MPTCP read: Connection reset by peer read: Connection reset by peer (duration 155ms) [FAIL] client exit code 3, server 3 netns ns1-FloSdv (listener) socket stat for 10006: TcpActiveOpens 2 0.0 TcpPassiveOpens 2 0.0 TcpEstabResets 2 0.0 TcpInSegs 274 0.0 TcpOutSegs 276 0.0 TcpOutRsts 3 0.0 TcpExtPruneCalled 2 0.0 TcpExtRcvPruned 1 0.0 TcpExtTCPPureAcks 104 0.0 TcpExtTCPRcvCollapsed 2 0.0 TcpExtTCPBacklogCoalesce 42 0.0 TcpExtTCPRcvCoalesce 43 0.0 TcpExtTCPChallengeACK 1 0.0 TcpExtTCPFromZeroWindowAdv 42 0.0 TcpExtTCPToZeroWindowAdv 41 0.0 TcpExtTCPWantZeroWindowAdv 13 0.0 TcpExtTCPOrigDataSent 164 0.0 TcpExtTCPDelivered 165 0.0 TcpExtTCPRcvQDrop 1 0.0 In the failing scenarios (TCP -> MPTCP), the involved sockets are actually plain TCP ones, as fallbacks for passive sockets at 2WHS time cause the MPTCP listeners to actually create 'plain' TCP sockets.

selftests: mptcp: connect: catch IO errors on listen side
IO errors were correctly printed to stderr, and propagated up to the
main loop for the server side, but the returned value was ignored. As a
consequence, the program for the listener side was no longer exiting
with an error code in case of IO issues.
Because of that, some issues might not have been seen. But very likely,
most issues either had an effect on the client side, or the file
transfer was not the expected one, e.g. the connection got reset before
the end. Still, it is better to fix this.
The main consequence of this issue is the error that was reported by the
selftests: the received and sent files were different, and the MIB
counters were not printed. Also, when such errors happened during the
'disconnect' tests, the program tried to continue until the timeout.
Now when an IO error is detected, the program exits directly with an
error.

selftests: openvswitch: add a simple test for tunnel metadata
This test ensures that upon receiving decapsulated packets from a tunnel interface in openvswitch, the tunnel metadata fields are properly populated. This partially covers interoperability of the kernel tunnel ports and openvswitch tunnels (LWT) and parsing and formatting of the tunnel metadata fields of the openvswitch netlink uAPI. Doing so, this test also ensures that fields and flags are properly extracted during decapsulation by the tunnel core code, serving as a regression test for the previously fixed issue with the DF bit not being extracted from the outer IP header. The ovs-dpctl.py script already supports all that is necessary for the tunnel ports for this test, so we only need to adjust the ovs_add_if() function to pass the '-t' port type argument in order to be able to create tunnel ports in the openvswitch datapath.

selftests/bpf: Fix "expression result unused" warnings with icecc
icecc is a compiler wrapper that distributes compile jobs over a build farm [1]. It works by sending toolchain binaries and preprocessed source code to remote machines. Unfortunately using it with BPF selftests causes build failures due to a clang bug [2]. The problem is that clang suppresses the -Wunused-value warning if the unused expression comes from a macro expansion. Since icecc compiles preprocessed source code, this information is not available. This leads to -Wunused-value false positives. obj_new_no_struct() and obj_new_acq() use the bpf_obj_new() macro and discard the result. arena_spin_lock_slowpath() uses two macros that produce values and ignores the results. Add (void) casts to explicitly indicate that this is intentional and suppress the warning. An alternative solution is to change the macros to not produce values. This would work today for the arena_spin_lock_slowpath() issue, but in the future there may appear users who need them. Another potential solution is to replace these macros with functions. Unfortunately this would not work, because these macros work with unknown types and control flow.

selftests/bpf: Extend crypto_sanity selftest with invalid dst buffer
Small cleanup and test extension to probe the bpf_crypto_{encrypt,decrypt}()
kfunc when a bad dst buffer is passed in to assert that an error is returned.
Also, encrypt_sanity() and skb_crypto_setup() were explicit to set the global
status variable to zero before any test, so do the same for decrypt_sanity().
Do not explicitly zero the on-stack err before bpf_crypto_ctx_create() given
the kfunc is expected to do it internally for the success case.

Pull vfs fixes from Christian Brauner:
"fuse:
- Prevent opening of non-regular backing files.
Fuse doesn't support non-regular files anyway.
- Check whether copy_file_range() returns a larger size than
requested.
- Prevent overflow in copy_file_range() as fuse currently only
supports 32-bit sized copies.
- Cache the blocksize value if the server returned a new value as
inode->i_blkbits isn't modified directly anymore.
- Fix i_blkbits handling for iomap partial writes.
By default i_blkbits is set to PAGE_SIZE which causes iomap to mark
the whole folio as uptodate even on a partial write. But fuseblk
filesystems support choosing a blocksize smaller than PAGE_SIZE
risking data corruption. Simply enforce PAGE_SIZE as blocksize for
fuseblk's internal inode for now.
- Prevent out-of-bounds acces in fuse_dev_write() when the number of
bytes to be retrieved is truncated to the fc->max_pages limit.
virtiofs:
- Fix page faults for DAX page addresses.
Misc:
- Tighten file handle decoding from userns.
Check that the decoded dentry itself has a valid idmapping in the
user namespace.
- Fix mount-notify selftests.
- Fix some indentation errors.
- Add an FMODE_ flag to indicate IOCB_HAS_METADATA availability.
This will be moved to an FOP_* flag with a bit more rework needed
for that to happen not suitable for a fix.
- Don't silently ignore metadata for sync read/write.
- Don't pointlessly log warning when reading coredump sysctls"

netfilter: nft_flowtable.sh: re-run with random mtu sizes
Jakub says: nft_flowtable.sh is one of the most flake-atious test for netdev CI currently :( The root cause is two-fold: 1. the failing part of the test is supposed to make sure that ip fragments are forwarded for offloaded flows.

fault context during SEA injection and preventing the use of
RASv1p1 fault injection hardware
- Ensure that page table destruction when a VM is destroyed gives an

- Large fix to KVM's infrastructure for managing guest context loaded

- Fix AT S12 emulation to actually perform stage-2 translation when
necessary

RISC-V:
- Fix pte settings within kvm_riscv_gstage_ioremap()
- Fix comments in kvm_riscv_check_vcpu_requests()
- Fix stack overrun when setting vlenb via ONE_REG
x86:
- Use array_index_nospec() to sanitize the target vCPU ID when handling PV
IPIs and yields as the ID is guest-controlled.
- Drop a superfluous cpumask_empty() check when reclaiming SEV memory, as
the common case, by far, is that at least one CPU will have entered the
VM, and wbnoinvd_on_cpus_mask() will naturally handle the rare case where
the set of have_run_cpus is empty.

ublk selftests: add --no_ublk_fixed_fd for not using registered ublk char device
Add a new command line option --no_ublk_fixed_fd that excludes the ublk control device (/dev/ublkcN) from io_uring's registered files array. When this option is used, only backing files are registered starting from index 1, while the ublk control device is accessed using its raw file descriptor. Add ublk_get_registered_fd() helper function that returns the appropriate file descriptor for use with io_uring operations. Key optimizations implemented: - Cache UBLKS_Q_NO_UBLK_FIXED_FD flag in ublk_queue.flags to avoid reading dev->no_ublk_fixed_fd in fast path - Cache ublk char device fd in ublk_queue.ublk_fd for fast access - Update ublk_get_registered_fd() to use ublk_queue * parameter - Update io_uring_prep_buf_register/unregister() to use ublk_queue * - Replace ublk_device * access with ublk_queue * access in fast paths Also pass --no_ublk_fixed_fd to test_stress_04.sh for covering plain ublk char device mode.

selftests/mm: fix FORCE_READ to read input value correctly
FORCE_READ() converts input value x to its pointer type then reads from
address x. This is wrong. If x is a non-pointer, it would be caught it
easily. But all FORCE_READ() callers are trying to read from a pointer
and FORCE_READ() basically reads a pointer to a pointer instead of the
original typed pointer. Almost no access violation was found, except the
one from split_huge_page_test.
Fix it by implementing a simplified READ_ONCE() instead.

"A set of fixes for block that should go into this tree. A bit larger
than what I usually have at this point in time, a lot of that is the
continued fixing of the lockdep annotation for queue freezing that we
recently added, which has highlighted a number of little issues here
and there. This contains:
- MD pull request via Yu:
- Add a legacy_async_del_gendisk mode, to prevent a user tools
regression. New user tools releases will not use such a mode,
the old release with a new kernel now will have warning about
deprecated behavior, and we prepare to remove this legacy mode
after about a year later
- The rename in kernel causing user tools build failure, revert
the rename in mdp_superblock_s
- Fix a regression that interrupted resync can be shown as
recover from mdstat or sysfs
- Improve file size detection for loop, particularly for networked
file systems, by using getattr to get the size rather than the
cached inode size.
- Hotplug CPU lock vs queue freeze fix
- Lockdep fix while updating the number of hardware queues
- Fix stacking for PI devices
- Silence bio_check_eod() for the known case of device removal where
the size is truncated to 0 sectors"

selftests: tls: add tests for zero-length records
Test various combinations of zero-length records. Unfortunately, kernel cannot be coerced into producing those, so hardcode the ciphertext messages in the test.

selftests: bonding: add test for passive LACP mode
Add a selftest to verify bonding behavior when `lacp_active` is set to `off`. The test checks the following: - The passive LACP bond should not send LACPDUs before receiving a partner's LACPDU. - The transmitted LACPDUs must not include the active flag. - After transitioning to EXPIRED and DEFAULTED states, the passive side should still not initiate LACPDUs.

selftests: harness: Rename is_signed_type() to avoid collision with overflow.h
Rename is_signed_type() to is_signed_var() to avoid colliding with a macro
of the same name defined by tools' linux/overflow.h. This fixes warnings
(and presumably potential test failures) in tests that utilize the
selftests harness and happen to (indirectly) include overflow.h.

Use a separate definition, at least for now, as many selftests build
without tools/include in their include path.

selftests/damon: fix selftests by installing drgn related script
drgn_dump_damon_status is not installed during kselftest setup. It can
break other tests which depend on drgn_dump_damon_status. Install
drgn_dump_damon_status files to fix broken test.
