It seems that the perf was depending on the rcuidle # tracepoints to make RCU watch when it wasn't. # # The real fix will be to have perf use SRCU instead of depending on # RCU watching, but that can't be done until SRCU is safe to use in # NMI context (Paul's working on that). # # - The second bug fix is for a bug that's been periodically making my # tests fail randomly for some time. I haven't had time to track it # down, but finally have. It has to do with stressing NMIs (via perf) # while enabling or disabling ftrace function handling with lockdep # enabled. # # If an interrupt happens and just as it returns, it sets lockdep # back to "interrupts enabled" but before it returns an NMI is # triggered, and if this happens while printk_nmi_enter has a # breakpoint attached to it (because ftrace is converting it to or # from nop to call fentry), the breakpoint trap also calls into # lockdep, and since returning from the NMI to a interrupt handler, # interrupts were disabled when the NMI went off, lockdep keeps its # state as interrupts disabled when it returns back from the # interrupt handler where interrupts are enabled. # # This causes lockdep_assert_irqs_enabled() to trigger a false # positive" # # * tag 'trace-v4.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: # printk/tracing: Do not trace printk_nmi_enter() # tracing: Add back in rcu_irq_enter/exit_irqson() for rcuidle tracepoints # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < git log --format=%s --max-count=1 be65e2595b4c1fbeceba336d8ee83406726b1d8d # < make -s -j 120 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allmodconfig # make -s -j 120 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- /kisskb/src/scripts/unifdef.c: In function 'Mpass': /kisskb/src/scripts/unifdef.c:453:28: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); } ^~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/fs/ocfs2/dlmglue.c:99:30: warning: 'lockdep_keys' defined but not used [-Wunused-variable] static struct lock_class_key lockdep_keys[OCFS2_NUM_LOCK_TYPES]; ^~~~~~~~~~~~ /kisskb/src/lib/test_hexdump.c: In function 'test_hexdump_prepare_test.isra.0': /kisskb/src/lib/test_hexdump.c:102:3: warning: 'strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] strncpy(p, q, amount); ^~~~~~~~~~~~~~~~~~~~~ /kisskb/src/lib/test_hexdump.c:100:19: note: length computed here size_t amount = strlen(q); ^~~~~~~~~ /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
