In original NMI handler, NMI reason io port (0x61) is only processed on BSP. This makes it impossible to hot-remove BSP. To solve the issue, a raw spinlock is used to allow the port to be processed on any CPU.

With priorities in place and no one really understanding the difference between DIE_NMI and DIE_NMI_IPI, just remove DIE_NMI_IPI and convert everyone to DIE_NMI. This also simplifies default_do_nmi() a little bit. Instead of calling the die_notifier in both the if and else part, just pull it out and call it before the if-statement. This has the side benefit of avoiding a call to the ioport to see if there is an external NMI sitting around until after the (more frequent) internal NMIs are dealt with.

In order to consolidate the NMI die_chain events, we need to setup the priorities for the die notifiers. I started by defining a bunch of common priorities that can be used by the notifier blocks. Then I modified the notifier blocks to use the newly created priorities. Now that the priorities are straightened out, it should be easier to remove the event DIE_NMI_IPI.

They are a handful of places in the code that register a die_notifier as a catch all in case no claims the NMI. Unfortunately, they trigger on events like DIE_NMI and DIE_NMI_IPI, which depending on when they registered may collide with other handlers that have the ability to determine if the NMI is theirs or not. The function unknown_nmi_error() makes one last effort to walk the die_chain when no one else has claimed the NMI before spitting out messages that the NMI is unknown. This is a better spot for these devices to execute any code without colliding with the other handlers. The two drivers modified are only compiled on x86 arches I believe, so they shouldn't be affected by other arches that may not have DIE_NMIUNKNOWN defined.

Replace the NMI related magic numbers with symbol constants. Memory parity error is only valid for IBM PC-AT, newer machine use bit 7 (0x80) of 0x61 port for PCI SERR. While memory error is usually reported via MCE. So corresponding function name and kernel log string is changed. But on some machines, PCI SERR line is still used to report memory errors. This is used by EDAC, so corresponding EDAC call is reserved.

Since commit 69aad6f1(perf tools: Introduce event selectors), only perf_event_attr::type and ::config are passed to event selector, which makes perf tool not work correctly. For example, PEBS does not work because perf_event_attr::precise_ip is not passed to the syscall.

I found when specifying all tracepoints with -e to one of subcommand, such as 'stat', the program will trigger a buffer overflow error, like this: *** buffer overflow detected ***: ./perf terminated ======= Backtrace: ========= /lib64/libc.so.6(__fortify_fail+0x37)[0x382cefb2c7] .... The tracepoints are separated by comma, something like this: $ perf stat -a -e `perf list |grep Tracepoint|awk -F'[' '{gsub(/[[:space:]]+/,"",$1);array[FNR]=$1}END{outputs=array[1];for (i=2;i<=FNR;i++){ outputs=outputs "," array[i];};print outputs}'` The root reason of this problem is that store_event_type() is called for all events, and will overflow the 'filename' at: strncat(filename, orgname, strlen(orgname)); This patch fixes it by calling store_event_type() only when the event name has been found.

This patch fixes the usage of the perf_event.h header file between command modules and the supporting code in util. It is necessary to ensure that ALL files use the SAME perf_event.h header from the kernel source tree. There were a couple of #include <linux/perf_event.h> mixed with #include "../../perf_event.h". This caused issues on some distros because of mismatch in the layout of struct perf_event_attr. That eventually led perf stat to segfault. Cc: David S.

The spin_lock_debug/rcu_cpu_stall detector uses trigger_all_cpu_backtrace() to dump cpu backtrace. Therefore it is possible that trigger_all_cpu_backtrace() could be called at the same time on different CPUs, which triggers and 'unknown reason NMI' warning. The following case illustrates the problem: CPU1 CPU2 ... CPU N trigger_all_cpu_backtrace() set "backtrace_mask" to cpu mask | generate NMI interrupts generate NMI interrupts ... \ | / \ | / The "backtrace_mask" will be cleaned by the first NMI interrupt at nmi_watchdog_tick(), then the following NMI interrupts generated by other cpus's arch_trigger_all_cpu_backtrace() will be taken as unknown reason NMI interrupts. This patch uses a test_and_set to avoid the problem, and stop the arch_trigger_all_cpu_backtrace() from calling to avoid dumping a double cpu backtrace info when there is already a trigger_all_cpu_backtrace() in progress.

The preferred source address is currently ignored for local routes, which results in all local connections having a src address that is the same as the local dst address. Fix this by respecting the preferred source address when it is provided for local routes. This bug can be demonstrated as follows: # ifconfig dummy0 192.168.0.1 # ip route show table local | grep local.*dummy0 local 192.168.0.1 dev dummy0 proto kernel scope host src 192.168.0.1 # ip route change table local local 192.168.0.1 dev dummy0 \ proto kernel scope host src 127.0.0.1 # ip route show table local | grep local.*dummy0 local 192.168.0.1 dev dummy0 proto kernel scope host src 127.0.0.1 We now establish a local connection and verify the source IP address selection: # nc -l 192.168.0.1 3128 & # nc 192.168.0.1 3128 & # netstat -ant | grep 192.168.0.1:3128.*EST tcp 0 0 192.168.0.1:3128 192.168.0.1:33228 ESTABLISHED tcp 0 0 192.168.0.1:33228 192.168.0.1:3128 ESTABLISHED Signed-off-by: Joel Sing <jsing@google.com> Signed-off-by: David S.
