[for-linus][PATCH 6/7] ftrace: Correct preemption accounting for function tracing.

by Steven Rostedt

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> The function tracer should record the preemption level at the point when the function is invoked. If the tracing subsystem decrement the preemption counter it needs to correct this before feeding the data into the trace buffer. This was broken in the commit cited below while shifting the preempt-disabled section. Use tracing_gen_ctx_dec() which properly subtracts one from the preemption counter on a preemptible kernel.

[for-linus][PATCH 4/7] fprobe: Fix accounting of when to unregister from function graph

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> When adding a new fprobe, it will update the function hash to the functions the fprobe is attached to and register with function graph to have it call the registered functions. The fprobe_graph_active variable keeps track of the number of fprobes that are using function graph. If two fprobes attach to the same function, it increments the fprobe_graph_active for each of them. But when they are removed, the first fprobe to be removed will see that the function it is attached to is also used by another fprobe and it will not remove that function from function_graph. The logic will skip decrementing the fprobe_graph_active variable. This causes the fprobe_graph_active variable to not go to zero when all fprobes are removed, and in doing so it does not unregister from function graph. As the fgraph ops hash will now be empty, and an empty filter hash means all functions are enabled, this triggers function graph to add a callback to the fprobe infrastructure for every function! # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # echo "f:myevent2 kernel_clone%return" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc0024000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # > /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions trace_initcall_start_cb (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 run_init_process (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 try_to_run_init_process (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 x86_pmu_show_pmu_cap (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 cleanup_rapl_pmus (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_free_pcibus_map (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_types_exit (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_pci_exit.part.0 (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 kvm_shutdown (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 vmx_dump_msrs (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 [..] # cat /sys/kernel/tracing/enabled_functions | wc -l 54702 If a fprobe is being removed and all its functions are also traced by other fprobes, still decrement the fprobe_graph_active counter.

[for-linus][PATCH 3/7] fprobe: Always unregister fgraph function from ops

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> When the last fprobe is removed, it calls unregister_ftrace_graph() to remove the graph_ops from function graph. The issue is when it does so, it calls return before removing the function from its graph ops via ftrace_set_filter_ips(). This leaves the last function lingering in the fprobe's fgraph ops and if a probe is added it also enables that last function (even though the callback will just drop it, it does add unneeded overhead to make that call). # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # echo "f:myevent2 schedule_timeout" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 schedule_timeout (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # > /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions # echo "f:myevent3 kmem_cache_free" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kmem_cache_free (1) tramp: 0xffffffffc0219000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 schedule_timeout (1) tramp: 0xffffffffc0219000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 The above enabled a fprobe on kernel_clone, and then on schedule_timeout. The content of the enabled_functions shows the functions that have a callback attached to them. The fprobe attached to those functions properly. Then the fprobes were cleared, and enabled_functions was empty after that. But after adding a fprobe on kmem_cache_free, the enabled_functions shows that the schedule_timeout was attached again. This is because it was still left in the fprobe ops that is used to tell function graph what functions it wants callbacks from.

[for-linus][PATCH 1/7] ftrace: Fix accounting of adding subops to a manager ops

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> Function graph uses a subops and manager ops mechanism to attach to ftrace. The manager ops connects to ftrace and the functions it connects to is defined by a list of subops that it manages. The function hash that defines what the above ops attaches to limits the functions to attach if the hash has any content. If the hash is empty, it means to trace all functions. The creation of the manager ops hash is done by iterating over all the subops hashes. If any of the subops hashes is empty, it means that the manager ops hash must trace all functions as well. The issue is in the creation of the manager ops. When a second subops is attached, a new hash is created by starting it as NULL and adding the subops one at a time. But the NULL ops is mistaken as an empty hash, and once an empty hash is found, it stops the loop of subops and just enables all functions. # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # echo "f:myevent2 schedule_timeout" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions trace_initcall_start_cb (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 run_init_process (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 try_to_run_init_process (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 x86_pmu_show_pmu_cap (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 cleanup_rapl_pmus (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_free_pcibus_map (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_types_exit (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_pci_exit.part.0 (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 kvm_shutdown (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 vmx_dump_msrs (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 vmx_cleanup_l1d_flush (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 [..] Fix this by initializing the new hash to NULL and if the hash is NULL do not treat it as an empty hash but instead allocate by copying the content of the first sub ops. Then on subsequent iterations, the new hash will not be NULL, but the content of the previous subops. If that first subops attached to all functions, then new hash may assume that the manager ops also needs to attach to all functions.

[PATCH stable 5.10.y-6.12.y] arm64: mte: Do not allow PROT_MTE on MAP_HUGETLB user mappings

by Catalin Marinas

PROT_MTE (memory tagging extensions) is not supported on all user mmap() types for various reasons (memory attributes, backing storage, CoW handling). The arm64 arch_validate_flags() function checks whether the VM_MTE_ALLOWED flag has been set for a vma during mmap(), usually by arch_calc_vm_flag_bits(). Linux prior to 6.13 does not support PROT_MTE hugetlb mappings. This was added by commit 25c17c4b55de ("hugetlb: arm64: add mte support"). However, earlier kernels inadvertently set VM_MTE_ALLOWED on (MAP_ANONYMOUS | MAP_HUGETLB) mappings by only checking for MAP_ANONYMOUS. Explicitly check MAP_HUGETLB in arch_calc_vm_flag_bits() and avoid setting VM_MTE_ALLOWED for such mappings. Fixes: 9f3419315f3c ("arm64: mte: Add PROT_MTE support to mmap() and mprotect()") Cc: <stable(a)vger.kernel.org> # 5.10.x-6.12.x Reported-by: Naresh Kamboju <naresh.kamboju(a)linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas(a)arm.com> --- Hi Greg, This patch applies cleanly on top of the stable-rc/linux-6.12.y to 5.10.y LTS, so I'm only sending it once. It's not for 6.13 onwards since those kernels support hugetlbfs with MTE.

[PATCH] drm/radeon: Add error handlings for r420 cp errata initiation

by Wentao Liang

In r420_cp_errata_init(), the RESYNC information is stored even when the Scratch register is not correctly allocated. Change the return type of r420_cp_errata_init() from void to int to propagate errors to the caller. Add error checking after radeon_scratch_get() to ensure RESYNC information is stored to an allocated address. Log an error message and return the error code immediately when radeon_scratch_get() fails. Additionally, handle the return value of r420_cp_errata_init() in r420_startup() to log an appropriate error message and propagate the error if initialization fails.
