objtool changes for v6.5:
- Build footprint & performance improvements:
- Reduce memory usage with CONFIG_DEBUG_INFO=y
In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel, DWARF
creates almost 200 million relocations, ballooning objtool's peak heap
usage to 53GB. These patches reduce that to 25GB.
On a distro-type kernel with kernel IBT enabled, they reduce objtool's
peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
- Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output.
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
- Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
- Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it
- Remove unnecessary/unused variables
- Fixes for modern stack canary handling

RCU pull request for v6.5
This pull contains the following branches:
doc.2023.05.10a: Documentation updates
fixes.2023.05.11a: Miscellaneous fixes, perhaps most notably:
o Remove RCU_NONIDLE(). The new visibility of most of the idle
loop to RCU has obsoleted this API.
o Make the RCU_SOFTIRQ callback-invocation time limit also apply
to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
o Add a jiffies-based callback-invocation time limit to handle
long-running callbacks. (The local_clock() function is only
invoked once per 32 callbacks due to its high overhead.)
o Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs,
which fixes a bug that can occur on systems with non-contiguous
CPU numbering.
kvfree.2023.05.10a: kvfree_rcu updates
o Eliminate the single-argument variant of k[v]free_rcu() now
that all uses have been converted to k[v]free_rcu_mightsleep().
o Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks
too soon. Yes, this is closing the barn door after the horse
has escaped, but Murphy says that there will be more horses.
nocb.2023.05.11a: Callback-offloading updates
o Fix a number of bugs involving the shrinker and lazy callbacks.
rcu-tasks.2023.05.10a: Tasks RCU updates
torture.2023.05.15a: Torture-test updates
rcu-urgent.2023.06.06a: Urgent SRCU fix (already pulled)

- Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs, which
fixes a bug that can occur on systems with non-contiguous CPU
numbering.
kvfree_rcu updates:
- Eliminate the single-argument variant of k[v]free_rcu() now that
all uses have been converted to k[v]free_rcu_mightsleep().
- Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks too
soon. Yes, this is closing the barn door after the horse has
escaped, but Murphy says that there will be more horses.
Callback-offloading updates:
- Fix a number of bugs involving the shrinker and lazy callbacks.

Pull btrfs updates from David Sterba:
"Mainly core changes, refactoring and optimizations.
Performance is improved in some areas, overall there may be a
cumulative improvement due to refactoring that removed lookups in the
IO path or simplified IO submission tracking.
Core:
- submit IO synchronously for fast checksums (crc32c and xxhash),
remove high priority worker kthread
- read extent buffer in one go, simplify IO tracking, bio submission
and locking
- remove additional tracking of redirtied extent buffers, originally
added for zoned mode but actually not needed
- track ordered extent pointer in bio to avoid rbtree lookups during
IO
- scrub, use recovered data stripes as cache to avoid unnecessary
read
- in zoned mode, optimize logical to physical mappings of extents
- remove PageError handling, not set by VFS nor writeback
- cleanups, refactoring, better structure packing
- lots of error handling improvements
- more assertions, lockdep annotations
- print assertion failure with the exact line where it happens
- tracepoint updates
- more debugging prints
Performance:
- speedup in fsync(), better tracking of inode logged status can
avoid transaction commit
- IO path structures track logical offsets in data structures and
does not need to look it up
User visible changes:
- don't commit transaction for every created subvolume, this can
reduce time when many subvolumes are created in a batch
- print affected files when relocation fails
- trigger orphan file cleanup during START_SYNC ioctl
Notable fixes:
- fix crash when disabling quota and relocation
- fix crashes when removing roots from drity list
- fix transacion abort during relocation when converting from newer
profiles not covered by fallback
- in zoned mode, stop reclaiming block groups if filesystem becomes
read-only
- fix rare race condition in tree mod log rewind that can miss some
btree node slots
- with enabled fsverity, drop up-to-date page bit in case the
verification fails"

kselftest/arm64: Add a test case for TPIDR2 restore
Due to the fact that TPIDR2 is intended to be managed by libc we don't currently test modifying it via the signal context since that might disrupt libc's usage of it and cause instability. We can however test the opposite case with less risk, modifying TPIDR2 in a signal handler and making sure that the original value is restored after returning from the signal handler. Add a test which does this.

selftests: forwarding: Fix race condition in mirror installation
When mirroring to a gretap in hardware the device expects to be programmed with the egress port and all the encapsulating headers. This requires the driver to resolve the path the packet will take in the software data path and program the device accordingly. If the path cannot be resolved (in this case because of an unresolved neighbor), then mirror installation fails until the path is resolved. This results in a race that causes the test to sometimes fail. Fix this by setting the neighbor's state to permanent in a couple of tests, so that it is always valid. Fixes: |

Tracing fixes for 6.4:
- Fix MAINTAINERS file to point to proper mailing list for rtla and rv
The mailing list pointed to linux-trace-devel instead of
linux-trace-kernel. The former is for the tracing libraries
and the latter is for anything in the Linux kernel tree.
The wrong mailing list was used because linux-trace-kernel did not
exist when rtla and rv were created.
- User events:
. Fix matching of dynamic events to their user events
When user writes to dynamic_events file, a lookup of the
registered dynamic events are made, but there were some cases
that a match could be incorrectly made.
. Add auto cleanup of user events
Have the user events automatically get removed when the last
reference (file descriptor) is closed. This was asked for to
prevent leaks of user events hanging around needing admins
to clean them up.
. Add persistent logic (but not let user space use it yet)
In some cases, having a persistent user event (one that does not
get cleaned up automatically) is useful. But there's still
debates about how to expose this to user space. The infrastructure
is added, but the API is not.
. Update the selftests
Update the user event selftests to reflect the above changes.

selftests/mm: fix cross compilation with LLVM
Currently the MM selftests attempt to work out the target architecture by using CROSS_COMPILE or otherwise querying the host machine, storing the target architecture in a variable called MACHINE rather than the usual ARCH though as far as I can tell (including for x86_64) the value is the same as we would use for architecture. When cross compiling with LLVM we don't need a CROSS_COMPILE as LLVM can support many target architectures in a single build so this logic does not work, CROSS_COMPILE is not set and we end up selecting tests for the host rather than target architecture. Fix this by using the more standard ARCH to describe the architecture, taking it from the environment if specified.

selftests/harness: allow tests to be skipped during setup
Before executing each test from a fixture, FIXTURE_SETUP is run once. When SKIP is used in FIXTURE_SETUP, the setup function returns early but the test still proceeds to run, unless another SKIP macro is used within the test definition, leading to some code repetition. Therefore, allow tests to be skipped directly from the setup function.

Including fixes from wireless, and netfilter.
Selftests excluded - we have 58 patches and diff of +442/-199,
which isn't really small but perhaps with the exception of
the WiFi locking change it's old(ish) bugs.
We have no known problems with v6.4.
The selftest changes are rather large as MPTCP folks try to apply
Greg's guidance that selftest from torvalds/linux should be able
to run against stable kernels.
Last thing I should call out is the DCCP/UDP-lite deprecation notices,
we are fairly sure those are dead, but if we're wrong reverting them
back in won't be fun.
Current release - regressions:
- wifi:
- cfg80211: fix double lock bug in reg_wdev_chan_valid()
- iwlwifi: mvm: spin_lock_bh() to fix lockdep regression
Current release - new code bugs:
- handshake: remove fput() that causes use-after-free
Previous releases - regressions:
- sched: cls_u32: fix reference counter leak leading to overflow
- sched: cls_api: fix lockup on flushing explicitly created chain
Previous releases - always broken:
- nf_tables: integrate pipapo into commit protocol
- nf_tables: incorrect error path handling with NFT_MSG_NEWRULE,
fix dangling pointer on failure
- ping6: fix send to link-local addresses with VRF
- sched: act_pedit: parse L3 header for L4 offset, the skb may

- sched: act_ct: fix promotion of offloaded unreplied tuple
- sched: refuse to destroy an ingress and clsact Qdiscs if there
are lockless change operations in flight
- wifi: mac80211: fix handful of bugs in multi-link operation
- ipvlan: fix bound dev checking for IPv6 l3s mode
- eth: enetc: correct the indexes of highest and 2nd highest TCs
- eth: ice: fix XDP memory leak when NIC is brought up and down
Misc:
- add deprecation notices for UDP-lite and DCCP
- selftests: mptcp: skip tests not supported by old kernels
- sctp: handle invalid error codes without calling BUG()

Selftests excluded - we have 58 patches and diff of +442/-199, which
isn't really small but perhaps with the exception of the WiFi locking
change it's old(ish) bugs.
We have no known problems with v6.4.
The selftest changes are rather large as MPTCP folks try to apply
Greg's guidance that selftest from torvalds/linux should be able to
run against stable kernels.
Last thing I should call out is the DCCP/UDP-lite deprecation notices.
We are fairly sure those are dead, but if we're wrong reverting them
back in won't be fun.
Current release - regressions:
- wifi:
- cfg80211: fix double lock bug in reg_wdev_chan_valid()
- iwlwifi: mvm: spin_lock_bh() to fix lockdep regression
Current release - new code bugs:
- handshake: remove fput() that causes use-after-free
Previous releases - regressions:
- sched: cls_u32: fix reference counter leak leading to overflow
- sched: cls_api: fix lockup on flushing explicitly created chain
Previous releases - always broken:
- nf_tables: integrate pipapo into commit protocol
- nf_tables: incorrect error path handling with NFT_MSG_NEWRULE, fix
dangling pointer on failure
- ping6: fix send to link-local addresses with VRF
- sched: act_pedit: parse L3 header for L4 offset, the skb may not
have the offset saved
- sched: act_ct: fix promotion of offloaded unreplied tuple
- sched: refuse to destroy an ingress and clsact Qdiscs if there are
lockless change operations in flight
- wifi: mac80211: fix handful of bugs in multi-link operation
- ipvlan: fix bound dev checking for IPv6 l3s mode
- eth: enetc: correct the indexes of highest and 2nd highest TCs
- eth: ice: fix XDP memory leak when NIC is brought up and down
Misc:
- add deprecation notices for UDP-lite and DCCP
- selftests: mptcp: skip tests not supported by old kernels
- sctp: handle invalid error codes without calling BUG()"

selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET
Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful. This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value. Fixes: |

selftests/user_events: Adapt dyn_test to non-persist events
Now that user_events does not honor persist events the dynamic_events file cannot be easily used to test parsing and matching cases. Update dyn_test to use the direct ABI file instead of dynamic_events so that we still have testing coverage until persist events and dynamic_events file integration has been decided.

selftests/tc-testing: Remove configs that no longer exist
Some qdiscs and classifiers have recently been retired from kernel. However, tc-testing config is still cluttered with them which causes noise when using merge_config.sh script to update existing config for tc-testing compatibility. Remove the config settings for affected qdiscs and classifiers. Fixes: |

selftests/tc-testing: Fix SFB db test
Setting very small value of db like 10ms introduces rounding errors when
converting to/from jiffies on some kernel configs. For example, on 250hz
the actual value will be set to 12ms which causes the test to fail:
# $ sudo ./tdc.py -d eth2 -e 3410
# -- ns/SubPlugin.__init__
# Test 3410: Create SFB with db setting
#
# All test results:
#
# 1..1
# not ok 1 3410 - Create SFB with db setting
# Could not match regex pattern. Verify command output:
# qdisc sfb 1: root refcnt 2 rehash 600s db 12ms limit 1000p max 25p target 20p increment 0.000503548 decrement 4.57771e-05 penalty_rate 10pps penalty_burst 20p
Set the value to 100ms instead which currently seem to work on 100hz,
250hz, 300hz and 1000hz kernel configs.

selftests/bpf: add a test for subprogram extables
In certain situations a program with subprograms may have a NULL extable entry. This should not happen, and when it does, it turns a single trap into multiple. Add a test case for further debugging and to prevent regressions. The test-case contains three essentially identical versions of the same test because just one program may not be sufficient to trigger the oops. This is due to the fact that the items are stored in a binary tree and have identical values so it's possible to sometimes find the ksym with the extable. With 3 copies, this has been reliable on this author's test systems. When triggered out of this test case, the oops looks like this: BUG: kernel NULL pointer dereference, address: 000000000000000c #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 1132 Comm: test_progs Tainted: G OE 6.4.0-rc3+ #2 RIP: 0010:cmp_ex_search+0xb/0x30 Code: cc cc cc cc e8 36 cb 03 00 66 0f 1f 44 00 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 f3 0f 1e fa 55 48 89 e5 48 8b 07 <48> 63 0e 48 01 f1 31 d2 48 39 c8 19 d2 48 39 c8 b8 01 00 00 00 0f RSP: 0018:ffffb30c4291f998 EFLAGS: 00010006 RAX: ffffffffc00b49da RBX: 0000000000000002 RCX: 000000000000000c RDX: 0000000000000002 RSI: 000000000000000c RDI: ffffb30c4291f9e8 RBP: ffffb30c4291f998 R08: ffffffffab1a42d0 R09: 0000000000000001 R10: 0000000000000000 R11: ffffffffab1a42d0 R12: ffffb30c4291f9e8 R13: 000000000000000c R14: 000000000000000c R15: 0000000000000000 FS: 00007fb5d9e044c0(0000) GS:ffff92e95ee00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000000000000c CR3: 000000010c3a2005 CR4: 00000000007706f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 PKRU: 55555554 Call Trace: <TASK> bsearch+0x41/0x90 ? __pfx_cmp_ex_search+0x10/0x10 ? bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c search_extable+0x3b/0x60 ? bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c search_bpf_extables+0x10d/0x190 ? bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c search_exception_tables+0x5d/0x70 fixup_exception+0x3f/0x5b0 ? look_up_lock_class+0x61/0x110 ? __lock_acquire+0x6b8/0x3560 ? __lock_acquire+0x6b8/0x3560 ? __lock_acquire+0x6b8/0x3560 kernelmode_fixup_or_oops+0x46/0x110 __bad_area_nosemaphore+0x68/0x2b0 ? __lock_acquire+0x6b8/0x3560 bad_area_nosemaphore+0x16/0x20 do_kern_addr_fault+0x81/0xa0 exc_page_fault+0xd6/0x210 asm_exc_page_fault+0x2b/0x30 RIP: 0010:bpf_prog_45a7907e7114d0ff_handle_fexit_ret_subprogs3+0x2a/0x6c Code: f3 0f 1e fa 0f 1f 44 00 00 66 90 55 48 89 e5 f3 0f 1e fa 48 8b 7f 08 49 bb 00 00 00 00 00 80 00 00 4c 39 df 73 04 31 f6 eb 04 <48> 8b 77 00 49 bb 00 00 00 00 00 80 00 00 48 81 c7 7c 00 00 00 4c RSP: 0018:ffffb30c4291fcb8 EFLAGS: 00010282 RAX: 0000000000000001 RBX: 0000000000000001 RCX: 0000000000000000 RDX: 00000000cddf1af1 RSI: 000000005315a00d RDI: ffffffffffffffea RBP: ffffb30c4291fcb8 R08: ffff92e644bf38a8 R09: 0000000000000000 R10: 0000000000000000 R11: 0000800000000000 R12: ffff92e663652690 R13: 00000000000001c8 R14: 00000000000001c8 R15: 0000000000000003 bpf_trampoline_251255721842_2+0x63/0x1000 bpf_testmod_return_ptr+0x9/0xb0 [bpf_testmod] ? bpf_testmod_test_read+0x43/0x2d0 [bpf_testmod] sysfs_kf_bin_read+0x60/0x90 kernfs_fop_read_iter+0x143/0x250 vfs_read+0x240/0x2a0 ksys_read+0x70/0xe0 __x64_sys_read+0x1f/0x30 do_syscall_64+0x68/0xa0 ? syscall_exit_to_user_mode+0x77/0x1f0 ? do_syscall_64+0x77/0xa0 ? irqentry_exit+0x35/0xa0 ? sysvec_apic_timer_interrupt+0x4d/0x90 entry_SYSCALL_64_after_hwframe+0x72/0xdc RIP: 0033:0x7fb5da00a392 Code: ac 00 00 f7 d8 64 89 02 48 c7 c0 ff ff ff ff eb be 0f 1f 80 00 00 00 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 0f 05 <48> 3d 00 f0 ff ff 77 56 c3 0f 1f 44 00 00 48 83 ec 28 48 89 54 24 RSP: 002b:00007ffc5b3cab68 EFLAGS: 00000246 ORIG_RAX: 0000000000000000 RAX: ffffffffffffffda RBX: 000055bee7b8b100 RCX: 00007fb5da00a392 RDX: 00000000000001c8 RSI: 0000000000000000 RDI: 0000000000000009 RBP: 00007ffc5b3caba0 R08: 0000000000000000 R09: 0000000000000037 R10: 000055bee7b8c2a7 R11: 0000000000000246 R12: 000055bee78f1f60 R13: 00007ffc5b3cae90 R14: 0000000000000000 R15: 0000000000000000 </TASK> Modules linked in: bpf_testmod(OE) nls_iso8859_1 dm_multipath scsi_dh_rdac scsi_dh_emc scsi_dh_alua intel_rapl_msr intel_rapl_common intel_uncore_frequency_common ppdev nfit crct10dif_pclmul crc32_pclmul psmouse ghash_clmulni_intel sha512_ssse3 aesni_intel parport_pc crypto_simd cryptd input_leds parport rapl ena i2c_piix4 mac_hid serio_raw ramoops reed_solomon pstore_blk drm pstore_zone efi_pstore autofs4 [last unloaded: bpf_testmod(OE)] CR2: 000000000000000c Though there may be some variation, depending on which suprogram triggers the bug.

selftests: mptcp: join: uniform listener tests
The alignment was different from the other tests because tabs were used
instead of spaces.
While at it, also use 'echo' instead of 'printf' to print the result to
keep the same style as done in the other sub-tests. And, even if it
should be better with, also remove 'stdbuf' and sed's '--unbuffered'
option because they are not used in the other subtests and they are not
available when using a minimal environment with busybox.

selftests: mptcp: join: support RM_ADDR for used endpoints or not
Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
At some points, a new feature caused internal behaviour changes we are
verifying in the selftests, see the Fixes tag below. It was not a UAPI
change but because in these selftests, we check some internal
behaviours, it is normal we have to adapt them from time to time after
having added some features.
It looks like there is no external sign we can use to predict the
expected behaviour. Instead of accepting different behaviours and thus
not really checking for the expected behaviour, we are looking here for
a specific kernel version. That's not ideal but it looks better than
removing the test because it cannot support older kernel versions.
