tracing: Add a tracepoint verification check at build time
If a tracepoint is defined via DECLARE_TRACE() or TRACE_EVENT() but never called (via the trace_<tracepoint>() function), its metadata is still around in memory and not discarded. When created via TRACE_EVENT() the situation is worse because the TRACE_EVENT() creates metadata that can be around 5k per trace event. Having unused trace events causes several thousand of wasted bytes. Add a verifier that injects a string of the name of the tracepoint it calls that is added to the discarded section "__tracepoint_check". For every builtin tracepoint, its name (which is saved in the in-memory section "__tracepoint_strings") will have its name also in the "__tracepoint_check" section if it is used. Add a new program that is run on build called tracepoint-update. This is executed on the vmlinux.o before the __tracepoint_check section is discarded (the section is discarded before vmlinux is created). This program will create an array of each string in the __tracepoint_check section and then sort it. Then it will walk the strings in the __tracepoint_strings section and do a binary search to check if its name is in the __tracepoint_check section. If it is not, then it is unused and a warning is printed. Note, this currently only handles tracepoints that are builtin and not in modules. Enabling this currently with a given config produces: warning: tracepoint 'sched_move_numa' is unused. warning: tracepoint 'sched_stick_numa' is unused. warning: tracepoint 'sched_swap_numa' is unused. warning: tracepoint 'pelt_hw_tp' is unused. warning: tracepoint 'pelt_irq_tp' is unused. warning: tracepoint 'rcu_preempt_task' is unused. warning: tracepoint 'rcu_unlock_preempted_task' is unused. warning: tracepoint 'xdp_bulk_tx' is unused. warning: tracepoint 'xdp_redirect_map' is unused. warning: tracepoint 'xdp_redirect_map_err' is unused. warning: tracepoint 'vma_mas_szero' is unused. warning: tracepoint 'vma_store' is unused. warning: tracepoint 'hugepage_set_pmd' is unused. warning: tracepoint 'hugepage_set_pud' is unused. warning: tracepoint 'hugepage_update_pmd' is unused. warning: tracepoint 'hugepage_update_pud' is unused. warning: tracepoint 'block_rq_remap' is unused. warning: tracepoint 'xhci_dbc_handle_event' is unused. warning: tracepoint 'xhci_dbc_handle_transfer' is unused. warning: tracepoint 'xhci_dbc_gadget_ep_queue' is unused. warning: tracepoint 'xhci_dbc_alloc_request' is unused. warning: tracepoint 'xhci_dbc_free_request' is unused. warning: tracepoint 'xhci_dbc_queue_request' is unused. warning: tracepoint 'xhci_dbc_giveback_request' is unused. warning: tracepoint 'tcp_ao_wrong_maclen' is unused. warning: tracepoint 'tcp_ao_mismatch' is unused. warning: tracepoint 'tcp_ao_key_not_found' is unused. warning: tracepoint 'tcp_ao_rnext_request' is unused. warning: tracepoint 'tcp_ao_synack_no_key' is unused. warning: tracepoint 'tcp_ao_snd_sne_update' is unused. warning: tracepoint 'tcp_ao_rcv_sne_update' is unused. Some of the above is totally unused but others are not used due to their "trace_" functions being inside configs, in which case, the defined tracepoints should also be inside those same configs. Others are architecture specific but defined in generic code, where they should either be moved to the architecture or be surrounded by #ifdef for the architectures they are for. This tool could be updated to process modules in the future. I'd like to thank Mathieu Desnoyers for suggesting using strings instead of pointers, as using pointers in vmlinux.o required handling relocations and it required implementing almost a full feature linker to do so. To enable this check, run the build with: make UT=1 Note, when all the existing unused tracepoints are removed from the build, the "UT=1" will be removed and this will always be enabled when tracepoints are configured to warn on any new tracepoints. The reason this isn't always enabled now is because it will introduce a lot of warnings for the current unused tracepoints, and all bisects would end at this commit for those warnings.

Pull smb client fixes from Steve French:
"smb client fixes, security and smbdirect improvements, and some minor cleanup:
- Important OOB DFS fix
- Fix various potential tcon refcount leaks
- smbdirect (RDMA) fixes (following up from test event a few weeks
ago):
- Fixes to improve and simplify handling of memory lifetime of
smbdirect_mr_io structures, when a connection gets disconnected
- Make sure we really wait to reach SMBDIRECT_SOCKET_DISCONNECTED
before destroying resources
- Make sure the send/recv submission/completion queues are large
enough to avoid ib_post_send() from failing under pressure
- convert cifs.ko to use the recommended crypto libraries (instead of
crypto_shash), this also can improve performance
- Three small cleanup patches"

tpm_crb: Add idle support for the Arm FF-A start method
According to the CRB over FF-A specification [1], a TPM that implements the ABI must comply with the TCG PTP specification. This requires support for the Idle and Ready states. This patch implements CRB control area requests for goIdle and cmdReady on FF-A based TPMs. The FF-A message used to notify the TPM of CRB updates includes a locality parameter, which provides a hint to the TPM about which locality modified the CRB. This patch adds a locality parameter to __crb_go_idle() and __crb_cmd_ready() to support this. [1] https://developer.arm.com/documentation/den0138/latest/ Signed-off-by: Stuart Yoder <stuart.yoder@arm.com> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org> |

arm64 fixes:
- Explicitly encode the XZR register if the value passed to
write_sysreg_s() is 0. The GIC CDEOI instruction is encoded as a
system register write with XZR as the source register. However, clang
does not honour the "Z" register constraint, leading to incorrect
code generation
- Ensure the interrupts (DAIF.IF) are unmasked when completing
single-step of a suspended breakpoint before calling
exit_to_user_mode(). With pseudo-NMIs, interrupts are (additionally)
masked at the PMR_EL1 register, handled by local_irq_*()

selftests/bpf: Fix redefinition of 'off' as different kind of symbol
This fixes the following build error
CLNG-BPF [test_progs] verifier_global_ptr_args.bpf.o
progs/verifier_global_ptr_args.c:228:5: error: redefinition of 'off' as
different kind of symbol
228 | u32 off;
| ^
The symbol 'off' was previously defined in
tools/testing/selftests/bpf/tools/include/vmlinux.h, which includes an
enum i40e_ptp_gpio_pin_state from
drivers/net/ethernet/intel/i40e/i40e_ptp.c:
enum i40e_ptp_gpio_pin_state {
end = -2,
invalid = -1,
off = 0,
in_A = 1,
in_B = 2,
out_A = 3,
out_B = 4,
};
This enum is included when CONFIG_I40E is enabled. As of commit

bpf: Do not disable preemption in bpf_test_run().
The timer mode is initialized to NO_PREEMPT mode by default, this disables preemption and force execution in atomic context causing issue on PREEMPT_RT configurations when invoking spin_lock_bh(), leading to the following warning: BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 6107, name: syz.0.17 preempt_count: 1, expected: 0 RCU nest depth: 1, expected: 1 Preemption disabled at: [<ffffffff891fce58>] bpf_test_timer_enter+0xf8/0x140 net/bpf/test_run.c:42 Fix this, by removing NO_PREEMPT/NO_MIGRATE mode check. Also, the test timer context no longer needs explicit calls to migrate_disable()/migrate_enable() with rcu_read_lock()/rcu_read_unlock(). Use helpers rcu_read_lock_dont_migrate() and rcu_read_unlock_migrate() instead.

arm64: debug: always unmask interrupts in el0_softstp()
We intend that EL0 exception handlers unmask all DAIF exceptions
before calling exit_to_user_mode().
When completing single-step of a suspended breakpoint, we do not call
local_daif_restore(DAIF_PROCCTX) before calling exit_to_user_mode(),
leaving all DAIF exceptions masked.
When pseudo-NMIs are not in use this is benign.
When pseudo-NMIs are in use, this is unsound. At this point interrupts
are masked by both DAIF.IF and PMR_EL1, and subsequent irq flag
manipulation may not work correctly. For example, a subsequent
local_irq_enable() within exit_to_user_mode_loop() will only unmask
interrupts via PMR_EL1 (leaving those masked via DAIF.IF), and
anything depending on interrupts being unmasked (e.g. delivery of
signals) will not work correctly.
This was detected by CONFIG_ARM64_DEBUG_PRIORITY_MASKING.
Move the call to `try_step_suspended_breakpoints()` outside of the check
so that interrupts can be unmasked even if we don't call the step handler.

arm64/sysreg: Fix GIC CDEOI instruction encoding
The GIC CDEOI system instruction requires the Rt field to be set to 0b11111
otherwise the instruction behaviour becomes CONSTRAINED UNPREDICTABLE.
Currenly, its usage is encoded as a system register write, with a constant
0 value:
write_sysreg_s(0, GICV5_OP_GIC_CDEOI)
While compiling with GCC, the 0 constant value, through these asm
constraints and modifiers ('x' modifier and 'Z' constraint combo):
asm volatile(__msr_s(r, "%x0") : : "rZ" (__val));
forces the compiler to issue the XZR register for the MSR operation (ie
that corresponds to Rt == 0b11111) issuing the right instruction encoding.
Unfortunately LLVM does not yet understand that modifier/constraint
combo so it ends up issuing a different register from XZR for the MSR
source, which in turns means that it encodes the GIC CDEOI instruction
wrongly and the instruction behaviour becomes CONSTRAINED UNPREDICTABLE
that we must prevent.
Add a conditional to write_sysreg_s() macro that detects whether it
is passed a constant 0 value and issues an MSR write with XZR as source
register - explicitly doing what the asm modifier/constraint is meant to
achieve through constraints/modifiers, fixing the LLVM compilation issue.

docs: rust: add section on imports formatting
`rustfmt`, by default, formats imports in a way that is prone to conflicts
while merging and rebasing, since in some cases it condenses several
items into the same line.
For instance, Linus mentioned [1] that the following case:
use crate::{
fmt,
page::AsPageIter,
};
is compressed by `rustfmt` into:
use crate::{fmt, page::AsPageIter};
which is undesirable.
Similarly, `rustfmt` may put several items in the same line even if the
braces span already multiple lines, e.g.:
use kernel::{
acpi, c_str,
device::{property, Core},
of, platform,
};
The options that control the formatting behavior around imports are
generally unstable, and `rustfmt` releases do not allow to use nightly
features, unlike the compiler and other Rust tooling [2].
For the moment, we can introduce a workaround to prevent `rustfmt`
from compressing the example above -- the "trailing empty comment":
use crate::{
fmt,
page::AsPageIter, //
};
which is reminiscent of the trailing comma behavior in other formatters.
We already used empty comments for formatting purposes in the past,
e.g. in commit

nvme/tcp: handle tls partially sent records in write_space()
With TLS enabled, records that are encrypted and appended to TLS TX
list can fail to see a retry if the underlying TCP socket is busy, for
example, hitting an EAGAIN from tcp_sendmsg_locked(). This is not known
to the NVMe TCP driver, as the TLS layer successfully generated a record.
Typically, the TLS write_space() callback would ensure such records are
retried, but in the NVMe TCP Host driver, write_space() invokes
nvme_tcp_write_space(). This causes a partially sent record in the TLS TX
list to timeout after not being retried.
This patch fixes the above by calling queue->write_space(), which calls
into the TLS layer to retry any pending records.

bpf: Fix memory leak in __lookup_instance error path
When __lookup_instance() allocates a func_instance structure but fails
to allocate the must_write_set array, it returns an error without freeing
the previously allocated func_instance. This causes a memory leak of 192
bytes (sizeof(struct func_instance)) each time this error path is triggered.
Fix by freeing 'result' on must_write_set allocation failure.
