[PATCH v7 4/4] cpufreq: qcom-hw: Fix the frequency returned by cpufreq_driver->get()

by Manivannan Sadhasivam

The cpufreq_driver->get() callback is supposed to return the current frequency of the CPU and not the one requested by the CPUFreq core. Fix it by returning the frequency that gets supplied to the CPU after the DCVS operation of EPSS/OSM.

[PATCH] drm/i915: Remove non-existent pipes from bigjoiner pipe mask

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> bigjoiner_pipes() doesn't consider that: - RKL only has three pipes - some pipes may be fused off This means that intel_atomic_check_bigjoiner() won't reject all configurations that would need a non-existent pipe. Instead we just keep on rolling witout actually having reserved the slave pipe we need. It's possible that we don't outright explode anywhere due to this since eg. for_each_intel_crtc_in_pipe_mask() will only walk the crtcs we've registered even though the passed in pipe_mask asks for more of them. But clearly the thing won't do what is expected of it when the required pipes are not present. Fix the problem by consulting the device info pipe_mask already in bigjoiner_pipes().

[for-linus][PATCH 13/13] tracing: Fix race where eprobes can be called before the event

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> The flag that tells the event to call its triggers after reading the event is set for eprobes after the eprobe is enabled. This leads to a race where the eprobe may be triggered at the beginning of the event where the record information is NULL. The eprobe then dereferences the NULL record causing a NULL kernel pointer bug. Test for a NULL record to keep this from happening.

[for-linus][PATCH 10/13] tracing: Fix wild-memory-access in register_synth_event()

by Steven Rostedt

From: Shang XiaoJing <shangxiaojing(a)huawei.com> In register_synth_event(), if set_synth_event_print_fmt() failed, then both trace_remove_event_call() and unregister_trace_event() will be called, which means the trace_event_call will call __unregister_trace_event() twice. As the result, the second unregister will causes the wild-memory-access. register_synth_event set_synth_event_print_fmt failed trace_remove_event_call event_remove if call->event.funcs then __unregister_trace_event (first call) unregister_trace_event __unregister_trace_event (second call) Fix the bug by avoiding to call the second __unregister_trace_event() by checking if the first one is called. general protection fault, probably for non-canonical address 0xfbd59c0000000024: 0000 [#1] SMP KASAN PTI KASAN: maybe wild-memory-access in range [0xdead000000000120-0xdead000000000127] CPU: 0 PID: 3807 Comm: modprobe Not tainted 6.1.0-rc1-00186-g76f33a7eedb4 #299 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.15.0-0-g2dd4b9b3f840-prebuilt.qemu.org 04/01/2014 RIP: 0010:unregister_trace_event+0x6e/0x280 Code: 00 fc ff df 4c 89 ea 48 c1 ea 03 80 3c 02 00 0f 85 0e 02 00 00 48 b8 00 00 00 00 00 fc ff df 4c 8b 63 08 4c 89 e2 48 c1 ea 03 <80> 3c 02 00 0f 85 e2 01 00 00 49 89 2c 24 48 85 ed 74 28 e8 7a 9b RSP: 0018:ffff88810413f370 EFLAGS: 00010a06 RAX: dffffc0000000000 RBX: ffff888105d050b0 RCX: 0000000000000000 RDX: 1bd5a00000000024 RSI: ffff888119e276e0 RDI: ffffffff835a8b20 RBP: dead000000000100 R08: 0000000000000000 R09: fffffbfff0913481 R10: ffffffff8489a407 R11: fffffbfff0913480 R12: dead000000000122 R13: ffff888105d050b8 R14: 0000000000000000 R15: ffff888105d05028 FS: 00007f7823e8d540(0000) GS:ffff888119e00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f7823e7ebec CR3: 000000010a058002 CR4: 0000000000330ef0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> __create_synth_event+0x1e37/0x1eb0 create_or_delete_synth_event+0x110/0x250 synth_event_run_command+0x2f/0x110 test_gen_synth_cmd+0x170/0x2eb [synth_event_gen_test] synth_event_gen_test_init+0x76/0x9bc [synth_event_gen_test] do_one_initcall+0xdb/0x480 do_init_module+0x1cf/0x680 load_module+0x6a50/0x70a0 __do_sys_finit_module+0x12f/0x1c0 do_syscall_64+0x3f/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd Link: https://lkml.kernel.org/r/20221117012346.22647-3-shangxiaojing@huawei.com Fixes: 4b147936fa50 ("tracing: Add support for 'synthetic' events") Signed-off-by: Shang XiaoJing <shangxiaojing(a)huawei.com> Cc: stable(a)vger.kernel.org Cc: <mhiramat(a)kernel.org> Cc: <zanussi(a)kernel.org> Cc: <fengguang.wu(a)intel.com> Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> --- kernel/trace/trace_events_synth.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/kernel/trace/trace_events_synth.c b/kernel/trace/trace_events_synth.c index e310052dc83c..29fbfb27c2b2 100644 --- a/kernel/trace/trace_events_synth.c +++ b/kernel/trace/trace_events_synth.c @@ -828,10 +828,9 @@ static int register_synth_event(struct synth_event *event) } ret = set_synth_event_print_fmt(call); - if (ret < 0) { + /* unregister_trace_event() will be called inside */ + if (ret < 0) trace_remove_event_call(call); - goto err; - } out: return ret; err: -- 2.35.1
