| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing/osnoise: Fix resetting of tracepoints\n\nIf a timerlat tracer is started with the osnoise option OSNOISE_WORKLOAD\ndisabled, but then that option is enabled and timerlat is removed, the\ntracepoints that were enabled on timerlat registration do not get\ndisabled. If the option is disabled again and timelat is started, then it\ntriggers a warning in the tracepoint code due to registering the\ntracepoint again without ever disabling it.\n\nDo not use the same user space defined options to know to disable the\ntracepoints when timerlat is removed. Instead, set a global flag when it\nis enabled and use that flag to know to disable the events.\n\n ~# echo NO_OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options\n ~# echo timerlat > /sys/kernel/tracing/current_tracer\n ~# echo OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options\n ~# echo nop > /sys/kernel/tracing/current_tracer\n ~# echo NO_OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options\n ~# echo timerlat > /sys/kernel/tracing/current_tracer\n\nTriggers:\n\n ------------[ cut here ]------------\n WARNING: CPU: 6 PID: 1337 at kernel/tracepoint.c:294 tracepoint_add_func+0x3b6/0x3f0\n Modules linked in:\n CPU: 6 UID: 0 PID: 1337 Comm: rtla Not tainted 6.13.0-rc4-test-00018-ga867c441128e-dirty #73\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014\n RIP: 0010:tracepoint_add_func+0x3b6/0x3f0\n Code: 48 8b 53 28 48 8b 73 20 4c 89 04 24 e8 23 59 11 00 4c 8b 04 24 e9 36 fe ff ff 0f 0b b8 ea ff ff ff 45 84 e4 0f 84 68 fe ff ff <0f> 0b e9 61 fe ff ff 48 8b 7b 18 48 85 ff 0f 84 4f ff ff ff 49 8b\n RSP: 0018:ffffb9b003a87ca0 EFLAGS: 00010202\n RAX: 00000000ffffffef RBX: ffffffff92f30860 RCX: 0000000000000000\n RDX: 0000000000000000 RSI: ffff9bf59e91ccd0 RDI: ffffffff913b6410\n RBP: 000000000000000a R08: 00000000000005c7 R09: 0000000000000002\n R10: ffffb9b003a87ce0 R11: 0000000000000002 R12: 0000000000000001\n R13: ffffb9b003a87ce0 R14: ffffffffffffffef R15: 0000000000000008\n FS: 00007fce81209240(0000) GS:ffff9bf6fdd00000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 000055e99b728000 CR3: 00000001277c0002 CR4: 0000000000172ef0\n Call Trace:\n <TASK>\n ? __warn.cold+0xb7/0x14d\n ? tracepoint_add_func+0x3b6/0x3f0\n ? report_bug+0xea/0x170\n ? handle_bug+0x58/0x90\n ? exc_invalid_op+0x17/0x70\n ? asm_exc_invalid_op+0x1a/0x20\n ? __pfx_trace_sched_migrate_callback+0x10/0x10\n ? tracepoint_add_func+0x3b6/0x3f0\n ? __pfx_trace_sched_migrate_callback+0x10/0x10\n ? __pfx_trace_sched_migrate_callback+0x10/0x10\n tracepoint_probe_register+0x78/0xb0\n ? __pfx_trace_sched_migrate_callback+0x10/0x10\n osnoise_workload_start+0x2b5/0x370\n timerlat_tracer_init+0x76/0x1b0\n tracing_set_tracer+0x244/0x400\n tracing_set_trace_write+0xa0/0xe0\n vfs_write+0xfc/0x570\n ? do_sys_openat2+0x9c/0xe0\n ksys_write+0x72/0xf0\n do_syscall_64+0x79/0x1c0\n entry_SYSCALL_64_after_hwframe+0x76/0x7e" |
