Impact: new perfcounters feature Enable usage of tracepoints as perf counter events. tracepoint event ids can be found in /debug/tracing/event/*/*/id and (for now) are represented as -65536+id in the type field. Signed-off-by:

Impact: fix boot crash When doing the generic context switch event I ran into some early boot hangs, which were caused by inf func recursion (event, fault, event, fault). I eventually tracked it down to event_list not being initialized at the time of the first event. Fix this. Signed-off-by:

Impact: build fix for powerpc Commit bd753921015e7905 ("perf_counter: software counter event infrastructure") introduced a use of TIF_PERF_COUNTERS into the core perfcounter code. This breaks the build on powerpc because we use a flag in a per-cpu area to signal wakeups on powerpc rather than a thread_info flag, because the thread_info flags have to be manipulated with atomic operations and are thus slower than per-cpu flags. This fixes the by changing the core to use an abstracted set_perf_counter_pending() function, which is defined on x86 to set the TIF_PERF_COUNTERS flag and on powerpc to set the per-cpu flag (paca->perf_counter_pending). It changes the previous powerpc definition of set_perf_counter_pending to not take an argument and adds a clear_perf_counter_pending, so as to simplify the definition on x86. On x86, set_perf_counter_pending() is defined as a macro. Defining it as a static inline in arch/x86/include/asm/perf_counters.h causes compile failures because <asm/perf_counters.h> gets included early in <linux/sched.h>, and the definitions of set_tsk_thread_flag etc. are therefore not available in <asm/perf_counters.h>. (On powerpc this problem is avoided by defining set_perf_counter_pending etc. in <asm/hw_irq.h>.) Signed-off-by:Paul Mackerras <paulus@samba.org>

Impact: fix boot crash on Intel Perfmon Version 1 systems Intel Perfmon v1 does not support the global MSRs, nor does it offer the generalized MSR ranges. So support v2 and later CPUs only. Also mark pmc_ops as read-mostly - to avoid false cacheline sharing. Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: -

Impact: build fix In order to compile a kernel with performance counter patches, <asm/irq_regs.h> has to be included to provide the declaration of struct pt_regs *get_irq_regs(void); [ This bug was masked by unrelated x86 header file changes in the x86 tree, but occurs in the tip:perfcounters/core standalone tree. ] Signed-off-by:

I noticed that the counter_list only includes top-level counters, thus perf_swcounter_event() will miss sw-counters in groups. Since perf_swcounter_event() also wants an RCU safe list, create a new event_list that includes all counters and uses RCU list ops and use call_rcu to free the counter structure. Signed-off-by:

We need to ensure the enabled=0 write happens before we start disabling the actual counters, so that a pcm_amd_enable() will not enable one underneath us. I think the race is impossible anyway, we always balance the ops within any one context and perform enable() with IRQs disabled. Signed-off-by:

AUDIT_USER_TTY, like all other messages sent from user-space, is sent NUL-terminated. Unlike other user-space audit messages, which come only from trusted sources, AUDIT_USER_TTY messages are processed using audit_log_n_untrustedstring(). This patch modifies AUDIT_USER_TTY handling to ignore the trailing NUL and use the "quoted_string" representation of the message if possible. Signed-off-by:

currently audit_log_n_untrustedstring() uses audit_string_contains_control() to check if the 'string' has any control characters. If the 'string' has an embedded NULL audit_string_contains_control() will return that the data has no control characters and will then pass the string to audit_log_n_string with the total length, not the length up to the first NULL. audit_log_n_string() does a memcpy of the entire length and so the actual audit record emitted may then contain a NULL and then whatever random memory is after the NULL. Since we want to log the entire octet stream (if we can't trust the data to be a string we can't trust that a NULL isn't actually a part of it) we should just consider NULL as a control character. If the caller is certain they want to stop at the first NULL they should be using audit_log_untrustedstring. Signed-off-by:

(updated) Added hunk that changes the comment, the rest is the same. EXECVE records contain a newline after every argument. auditd converts "\n" to " " so you cannot see newlines even in raw logs, but they're there nevertheless. If you're not using auditd, you need to work round them. These '\n' chars are can be easily replaced by spaces when creating record in kernel. Note there is no need for trailing '\n' in an audit record. record before this patch: "type=EXECVE msg=audit(1231421801.566:31): argc=4 a0=\"./test\"\na1=\"a\"\na2=\"b\"\na3=\"c\"\n" record after this patch: "type=EXECVE msg=audit(1231421801.566:31): argc=4 a0=\"./test\" a1=\"a\" a2=\"b\" a3=\"c\"" Signed-off-by:
