powerpc fixes for 6.8 #3
- Fix ftrace bug on boot caused by exit text sections with -fpatchable-function-entry.
- Fix accuracy of stolen time on pseries since the switch to VIRT_CPU_ACCOUNTING_GEN.
- Fix a crash in the IOMMU code when doing DLPAR remove.
- Set pt_regs->link on scv entry to fix BPF stack unwinding.
- Add missing PPC_FEATURE_BOOKE on 64-bit e5500/e6500, which broke gdb.
- Fix boot on some 6xx platforms with STRICT_KERNEL_RWX enabled.
- Fix build failures with KASAN enabled and 32KB stack size.
- Some other minor fixes.

"This is a bit of a big batch for rc4, but just due to holiday hangover
and because I didn't send any fixes last week due to a late revert
request. I think next week should be back to normal.

ARM:
* Avoid dropping the page refcount twice when freeing an unlinked
page-table subtree.
* Don't source the VFIO Kconfig twice
* Fix protected-mode locking order between kvm and vcpus
RISC-V:
* Fix steal-time related sparse warnings
x86:
* Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int"
* Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only
if the incoming events->nmi.pending is non-zero. If the target vCPU is in
the UNITIALIZED state, the spurious request will result in KVM exiting to
userspace, which in turn causes QEMU to constantly acquire and release
QEMU's global mutex, to the point where the BSP is unable to make forward
progress.
* Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being
incorrectly truncated, and ultimately causes KVM to think a fixed counter
has already been disabled (KVM thinks the old value is '0').
* Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace
that is ultimately ignored due to ignore_msrs=true doesn't zero the output
as intended.
Selftests cleanups and fixes:
* Remove redundant newlines from error messages.
* Delete an unused variable in the AMX test (which causes build failures when
compiling with -Werror).
* Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an
error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE,
and the test eventually got skipped).
* Fix TSC related bugs in several Hyper-V selftests.
* Fix a bug in the dirty ring logging test where a sem_post() could be left
pending across multiple runs, resulting in incorrect synchronization between
the main thread and the vCPU worker thread.
* Relax the dirty log split test's assertions on 4KiB mappings to fix false
positives due to the number of mappings for memslot 0 (used for code and
data that is NOT being dirty logged) changing, e.g. due to NUMA balancing.

selftests: tls: increase the wait in poll_partial_rec_async
Test runners on debug kernels occasionally fail with:
# # RUN tls_err.13_aes_gcm.poll_partial_rec_async ...
# # tls.c:1883:poll_partial_rec_async:Expected poll(&pfd, 1, 5) (0) == 1 (1)
# # tls.c:1870:poll_partial_rec_async:Expected status (256) == 0 (0)
# # poll_partial_rec_async: Test failed at step #17
# # FAIL tls_err.13_aes_gcm.poll_partial_rec_async
# not ok 699 tls_err.13_aes_gcm.poll_partial_rec_async
# # FAILED: 698 / 699 tests passed.
This points to the second poll() in the test which is expected
to wait for the sender to send the rest of the data.
Apparently under some conditions that doesn't happen within 5ms,
bump the timeout to 20ms.

KVM selftests fixes/cleanups (and one KVM x86 cleanup) for 6.8:
- Remove redundant newlines from error messages.
- Delete an unused variable in the AMX test (which causes build failures when
compiling with -Werror).
- Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an
error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE,
and the test eventually got skipped).
- Fix TSC related bugs in several Hyper-V selftests.
- Fix a bug in the dirty ring logging test where a sem_post() could be left
pending across multiple runs, resulting in incorrect synchronization between
the main thread and the vCPU worker thread.
- Relax the dirty log split test's assertions on 4KiB mappings to fix false
positives due to the number of mappings for memslot 0 (used for code and
data that is NOT being dirty logged) changing, e.g. due to NUMA balancing.
- Have KVM's gtod_is_based_on_tsc() return "bool" instead of an "int" (the
function generates boolean values, and all callers treat the return value as
a bool).

selftests: net: more pmtu.sh fixes
The netdev CI is reporting failures for the pmtu test:
[ 115.929264] br0: port 2(vxlan_a) entered forwarding state
# 2024/02/08 17:33:22 socat[7871] E bind(7, {AF=10 [0000:0000:0000:0000:0000:0000:0000:0000]:50000}, 28): Address already in use
# 2024/02/08 17:33:22 socat[7877] E write(7, 0x5598fb6ff000, 8192): Connection refused
# TEST: IPv6, bridged vxlan4: PMTU exceptions [FAIL]
# File size 0 mismatches exepcted value in locally bridged vxlan test
The root cause is apparently a socket created by a previous iteration
of the relevant loop still lasting in LAST_ACK state.
Note that even the file size check is racy, the receiver process dumping
the file could still be running in background
Allow the listener to bound on the same local port via SO_REUSEADDR and
collect file output file size only after the listener completion.

selftests: net: more strict check in net_helper
The helper waiting for a listener port can match any socket whose
hexadecimal representation of source or destination addresses
matches that of the given port.
Additionally, any socket state is accepted.
All the above can let the helper return successfully before the
relevant listener is actually ready, with unexpected results.
So far I could not find any related failure in the netdev CI, but
the next patch is going to make the critical event more easily
reproducible.
Address the issue matching the port hex only vs the relevant socket
field and additionally checking the socket state for TCP sockets.

selftests: net: cope with slow env in so_txtime.sh test
The mentioned test is failing in slow environments:
# SO_TXTIME ipv4 clock monotonic
# ./so_txtime: recv: timeout: Resource temporarily unavailable
not ok 1 selftests: net: so_txtime.sh # exit=1
Tuning the tolerance in the test binary is error-prone and doomed
to failures is slow-enough environment.
Just resort to suppress any error in such cases. Note to suppress
them we need first to refactor a bit the code moving it to explicit
error handling.

selftests: net: cope with slow env in gro.sh test
The gro self-tests sends the packets to be aggregated with
multiple write operations.
When running is slow environment, it's hard to guarantee that
the GRO engine will wait for the last packet in an intended
train.
The above causes almost deterministic failures in our CI for
the 'large' test-case.
Address the issue explicitly ignoring failures for such case
in slow environments (KSFT_MACHINE_SLOW==true).

Older glibc's netinet/in.h may leave IPPROTO_MPTCP undefined when

selftests: forwarding: Fix bridge locked port test flakiness
The redirection test case fails in the netdev CI on debug kernels
because an FDB entry is learned despite the presence of a tc filter that
redirects incoming traffic [1].
I am unable to reproduce the failure locally, but I can see how it can
happen given that learning is first enabled and only then the ingress tc
filter is configured. On debug kernels the time window between these two
operations is longer compared to regular kernels, allowing random
packets to be transmitted and trigger learning.
Fix by reversing the order and configure the ingress tc filter before
enabling learning.

Due to the linkwatch delayed work the carrier change is not always

Fix by busy waiting on the bridge port state until it changes to the

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Narrow down target/match revision to u8 in nft_compat.
2) Bail out with unused flags in nft_compat.
3) Restrict layer 4 protocol to u16 in nft_compat.
4) Remove static in pipapo get command that slipped through when
reducing set memory footprint.
5) Follow up incremental fix for the ipset performance regression,
this includes the missing gc cancellation, from Jozsef Kadlecsik.
6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0
as no filtering, from Felix Huettner.
7) Reject direction for NFT_CT_ID.
8) Use timestamp to check for set element expiration while transaction
is handled to prevent garbage collection from removing set elements
that were just added by this transaction. Packet path and netlink
dump/get path still use current time to check for expiration.
9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal.
10) map_index needs to be percpu and per-set, not just percpu.
At this time its possible for a pipapo set to fill the all-zero part
with ones and take the 'might have bits set' as 'start-from-zero' area.
From Florian Westphal. This includes three patches:
- Change scratchpad area to a structure that provides space for a
per-set-and-cpu toggle and uses it of the percpu one.
- Add a new free helper to prepare for the next patch.
- Remove the scratch_aligned pointer and makes AVX2 implementation
use the exact same memory addresses for read/store of the matching
state.

selftests: cmsg_ipv6: repeat the exact packet
cmsg_ipv6 test requests tcpdump to capture 4 packets, and sends until tcpdump quits. Only the first packet is "real", however, and the rest are basic UDP packets. So if tcpdump doesn't start in time it will miss the real packet and only capture the UDP ones. This makes the test fail on slow machine (no KVM or with debug enabled) 100% of the time, while it passes in fast environments. Repeat the "real" / expected packet. Fixes: |

KVM: selftests: Don't assert on exact number of 4KiB in dirty log split test
Drop dirty_log_page_splitting_test's assertion that the number of 4KiB pages remains the same across dirty logging being enabled and disabled, as the test doesn't guarantee that mappings outside of the memslots being dirty logged are stable, e.g. KVM's mappings for code and pages in memslot0 can be zapped by things like NUMA balancing. To preserve the spirit of the check, assert that (a) the number of 4KiB pages after splitting is _at least_ the number of 4KiB pages across all memslots under test, and (b) the number of hugepages before splitting adds up to the number of pages across all memslots under test. (b) is a little tenuous as it relies on memslot0 being incompatible with transparent hugepages, but that holds true for now as selftests explicitly madvise() MADV_NOHUGEPAGE for memslot0 (__vm_create() unconditionally specifies the backing type as VM_MEM_SRC_ANONYMOUS).

KVM: selftests: Fix a semaphore imbalance in the dirty ring logging test
When finishing the final iteration of dirty_log_test testcase, set
host_quit _before_ the final "continue" so that the vCPU worker doesn't
run an extra iteration, and delete the hack-a-fix of an extra "continue"
from the dirty ring testcase. This fixes a bug where the extra post to
sem_vcpu_cont may not be consumed, which results in failures in subsequent
runs of the testcases. The bug likely was missed during development as
x86 supports only a single "guest mode", i.e. there aren't any subsequent
testcases after the dirty ring test, because for_each_guest_mode() only
runs a single iteration.
For the regular dirty log testcases, letting the vCPU run one extra
iteration is a non-issue as the vCPU worker waits on sem_vcpu_cont if and
only if the worker is explicitly told to stop (vcpu_sync_stop_requested).
But for the dirty ring test, which needs to periodically stop the vCPU to
reap the dirty ring, letting the vCPU resume the guest _after_ the last
iteration means the vCPU will get stuck without an extra "continue".
However, blindly firing off an post to sem_vcpu_cont isn't guaranteed to
be consumed, e.g. if the vCPU worker sees host_quit==true before resuming
the guest. This results in a dangling sem_vcpu_cont, which leads to
subsequent iterations getting out of sync, as the vCPU worker will
continue on before the main task is ready for it to resume the guest,
leading to a variety of asserts, e.g.
==== Test Assertion Failure ====
dirty_log_test.c:384: dirty_ring_vcpu_ring_full
pid=14854 tid=14854 errno=22 - Invalid argument

8 0x000000000040206f: _start at ??:?

Alternatively, the test could simply reset the semaphores before each
testcase, but papering over hacks with more hacks usually ends in tears.

selftests/net: Amend per-netns counter checks
Selftests here check not only that connect()/accept() for
TCP-AO/TCP-MD5/non-signed-TCP combinations do/don't establish
connections, but also counters: those are per-AO-key, per-socket and
per-netns.
The counters are checked on the server's side, as the server listener
has TCP-AO/TCP-MD5/no keys for different peers. All tests run in
the same namespaces with the same veth pair, created in test_init().
After close() in both client and server, the sides go through
the regular FIN/ACK + FIN/ACK sequence, which goes in the background.
If the selftest has already started a new testing scenario, read
per-netns counters - it may fail in the end iff it doesn't expect
the TCPAOGood per-netns counters go up during the test.
Let's just kill both TCP-AO sides - that will avoid any asynchronous
background TCP-AO segments going to either sides.

selftests: net: let big_tcp test cope with slow env
In very slow environments, most big TCP cases including
segmentation and reassembly of big TCP packets have a good
chance to fail: by default the TCP client uses write size
well below 64K. If the host is low enough autocorking is
unable to build real big TCP packets.
Address the issue using much larger write operations.
Note that is hard to observe the issue without an extremely
slow and/or overloaded environment; reduce the TCP transfer
time to allow for much easier/faster reproducibility.

needs to be used as a prefix to be considered on a metric formula, detected via one
of the 'perf test' entries.
'perf test' fixes:
- Fix the creation of event selector lists on 'perf test' entries, by initializing
the sample ID flag, which is done by 'perf record', so this fix only the tests,
the common case isn't affected.
- Make 'perf list' respect debug settings (-v) to fix its 'perf test' entry.
- Fix 'perf script' test when python support isn't enabled.
- Special case 'perf script' tests on s390, where only DWARF call graphs are
supported and only on software events.
- Make 'perf daemon' signal test less racy.
Compiler warnings/errors:
- Remove needless malloc(0) call in 'perf top' that triggers -Walloc-size.
- Fix calloc() argument order to address error introduced in gcc-14.
Build:
- Make minimal shellcheck version to v0.6.0, avoiding the build to fail with older versions.
Sync kernel header copies:
- stat.h to pick STATX_MNT_ID_UNIQUE.
- msr-index.h to pick IA32_MKTME_KEYID_PARTITIONING.
- drm.h to pick DRM_IOCTL_MODE_CLOSEFB.
- unistd.h to pick {list,stat}mount, lsm_{[gs]et_self_attr,list_modules} syscall numbers.
- x86 cpufeatures to pick TDX, Zen, APIC MSR fence changes.
- x86's mem{cpy,set}_64.S used in 'perf bench'.

busy host it can fail.
Additionally the test starts again the same listener in the same
namespace on the same port, just after the previous connection
completed. Fast host can attempt starting the new server before the
old one really closed the socket.
Address the issues using the wait_local_port_listen helper and
explicitly waiting for the background listener process exit.

selftests: net: fix setup_ns usage in rtnetlink.sh
The setup_ns helper marks the testns global variable as
readonly. Later attempts to set such variable are unsuccessful,
causing a couple test failures.
Avoid completely the variable re-initialization and let the
function access the global value.

selftests: net: cut more slack for gro fwd tests.
The udpgro_fwd.sh self-tests are somewhat unstable. There are
a few timing constraints the we struggle to meet on very slow
environments.
Instead of skipping the whole tests in such envs, increase the
test resilience WRT very slow hosts: increase the inter-packets
timeouts, avoid resetting the counters every second and finally
disable reduce the background traffic noise.
Tested with:
for I in $(seq 1 100); do
./tools/testing/selftests/kselftest_install/run_kselftest.sh \
-t net:udpgro_fwd.sh || exit -1
done
in a slow environment.

selftests/landlock: Fix capability for net_test
CAP_NET_ADMIN allows to configure network interfaces, not CAP_SYS_ADMIN
which only allows to call unshare(2). Without this change, running
network tests as a non-root user but with all capabilities would fail at
the setup_loopback() step with "RTNETLINK answers: Operation not
permitted".
The issue is only visible when running tests with non-root users (i.e.
only relying on ambient capabilities). Indeed, when configuring the
network interface, the "ip" command is called, which may lead to the
special handling of capabilities for the root user by execve(2). If
root is the caller, then the inherited, permitted and effective
capabilities are all reset, which then includes CAP_NET_ADMIN. However,
if a non-root user is the caller, then ambient capabilities are masked
by the inherited ones, which were explicitly dropped.
To make execution deterministic whatever users are running the tests,
set the noroot secure bit for each test, and set the inheritable and
ambient capabilities to CAP_NET_ADMIN, the only capability that may be
required after an execve(2).
Factor out _effective_cap() into _change_cap(), and use it to manage
ambient capabilities with the new set_ambient_cap() and
clear_ambient_cap() helpers.
This makes it possible to run all Landlock tests with check-linux.sh

selftests: mptcp: join: stop transfer when check is done (part 2)
Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds on slow environments. While at it, use 'mptcp_lib_kill_wait()' helper everywhere, instead of on a specific one with 'kill_tests_wait()'. Fixes: |
