From 5910895f0e868d4f70303922ed00ccdc328b3c30 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Thu, 12 Sep 2013 14:10:25 -0400 Subject: random: fix the tracepoint for get_random_bytes(_arch) Fix a problem where get_random_bytes_arch() was calling the tracepoint get_random_bytes(). So add a new tracepoint for get_random_bytes_arch(), and make get_random_bytes() and get_random_bytes_arch() call their correct tracepoint. Also, add a new tracepoint for add_device_randomness() Signed-off-by: "Theodore Ts'o" --- include/trace/events/random.h | 33 ++++++++++++++++++++++++++++++++- 1 file changed, 32 insertions(+), 1 deletion(-) (limited to 'include/trace') diff --git a/include/trace/events/random.h b/include/trace/events/random.h index 422df19de732..2ffcaec5860a 100644 --- a/include/trace/events/random.h +++ b/include/trace/events/random.h @@ -7,6 +7,25 @@ #include #include +TRACE_EVENT(add_device_randomness, + TP_PROTO(int bytes, unsigned long IP), + + TP_ARGS(bytes, IP), + + TP_STRUCT__entry( + __field( int, bytes ) + __field(unsigned long, IP ) + ), + + TP_fast_assign( + __entry->bytes = bytes; + __entry->IP = IP; + ), + + TP_printk("bytes %d caller %pF", + __entry->bytes, (void *)__entry->IP) +); + DECLARE_EVENT_CLASS(random__mix_pool_bytes, TP_PROTO(const char *pool_name, int bytes, unsigned long IP), @@ -68,7 +87,7 @@ TRACE_EVENT(credit_entropy_bits, (void *)__entry->IP) ); -TRACE_EVENT(get_random_bytes, +DECLARE_EVENT_CLASS(random__get_random_bytes, TP_PROTO(int nbytes, unsigned long IP), TP_ARGS(nbytes, IP), @@ -86,6 +105,18 @@ TRACE_EVENT(get_random_bytes, TP_printk("nbytes %d caller %pF", __entry->nbytes, (void *)__entry->IP) ); +DEFINE_EVENT(random__get_random_bytes, get_random_bytes, + TP_PROTO(int nbytes, unsigned long IP), + + TP_ARGS(nbytes, IP) +); + +DEFINE_EVENT(random__get_random_bytes, get_random_bytes_arch, + TP_PROTO(int nbytes, unsigned long IP), + + TP_ARGS(nbytes, IP) +); + DECLARE_EVENT_CLASS(random__extract_entropy, TP_PROTO(const char *pool_name, int nbytes, int entropy_count, unsigned long IP), -- cgit v1.2.1
