Donenfeld <Jason@zx2c4.com> - Date: Wed Jan 12 17:18:08 2022 +0100 - - random: rather than entropy_store abstraction, use global - - Originally, the RNG used several pools, so having things abstracted out - over a generic entropy_store object made sense. These days, there's only - one input pool, and then an uneven mix of usage via the abstraction and - usage via &input_pool. Rather than this uneasy mixture, just get rid of - the abstraction entirely and have things always use the global. This - simplifies the code and makes reading it a bit easier. - -Upstream-Status: Backport [lttng-modules commit 98b7729a776bc5babb39345eeeba3cd1f60d8c9a] - -Change-Id: I1a2a14d7b6e69a047804e1e91e00fe002f757431 -Signed-off-by: Michael Jeanson <mjeanson@efficios.com> -Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> ---- - include/instrumentation/events/random.h | 81 ++++++++++++++++++++++++- - 1 file changed, 80 insertions(+), 1 deletion(-) - -diff --git a/include/instrumentation/events/random.h b/include/instrumentation/events/random.h -index ed05d26a..8cc88adb 100644 ---- a/include/instrumentation/events/random.h -+++ b/include/instrumentation/events/random.h -@@ -8,6 +8,36 @@ - #include <lttng/tracepoint-event.h> - #include <linux/writeback.h> - -+#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,17,0)) -+LTTNG_TRACEPOINT_EVENT_CLASS(random__mix_pool_bytes, -+ TP_PROTO(int bytes, unsigned long IP), -+ -+ TP_ARGS(bytes, IP), -+ -+ TP_FIELDS( -+ ctf_integer(int, bytes, bytes) -+ ctf_integer_hex(unsigned long, IP, IP) -+ ) -+) -+ -+LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(random__mix_pool_bytes, mix_pool_bytes, -+ -+ random_mix_pool_bytes, -+ -+ TP_PROTO(int bytes, unsigned long IP), -+ -+ TP_ARGS(bytes, IP) -+) -+ -+LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(random__mix_pool_bytes, mix_pool_bytes_nolock, -+ -+ random_mix_pool_bytes_nolock, -+ -+ TP_PROTO(int bytes, unsigned long IP), -+ -+ TP_ARGS(bytes, IP) -+) -+#else - LTTNG_TRACEPOINT_EVENT_CLASS(random__mix_pool_bytes, - TP_PROTO(const char *pool_name, int bytes, unsigned long IP), - -@@ -37,8 +67,24 @@ LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(random__mix_pool_bytes, mix_pool_bytes_noloc - - TP_ARGS(pool_name, bytes, IP) - ) -+#endif - --#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,2,0)) -+#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,17,0)) -+LTTNG_TRACEPOINT_EVENT_MAP(credit_entropy_bits, -+ -+ random_credit_entropy_bits, -+ -+ TP_PROTO(int bits, int entropy_count, unsigned long IP), -+ -+ TP_ARGS(bits, entropy_count, IP), -+ -+ TP_FIELDS( -+ ctf_integer(int, bits, bits) -+ ctf_integer(int, entropy_count, entropy_count) -+ ctf_integer_hex(unsigned long, IP, IP) -+ ) -+) -+#elif (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,2,0)) - LTTNG_TRACEPOINT_EVENT_MAP(credit_entropy_bits, - - random_credit_entropy_bits, -@@ -89,6 +135,38 @@ LTTNG_TRACEPOINT_EVENT_MAP(get_random_bytes, - ) - ) - -+#if (LTTNG_LINUX_VERSION_CODE >= LTTNG_KERNEL_VERSION(5,17,0)) -+LTTNG_TRACEPOINT_EVENT_CLASS(random__extract_entropy, -+ TP_PROTO(int nbytes, int entropy_count, unsigned long IP), -+ -+ TP_ARGS(nbytes, entropy_count, IP), -+ -+ TP_FIELDS( -+ ctf_integer(int, nbytes, nbytes) -+ ctf_integer(int, entropy_count, entropy_count) -+ ctf_integer_hex(unsigned long, IP, IP) -+ ) -+) -+ -+ -+LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(random__extract_entropy, extract_entropy, -+ -+ random_extract_entropy, -+ -+ TP_PROTO(int nbytes, int entropy_count, unsigned long IP), -+ -+ TP_ARGS(nbytes, entropy_count, IP) -+) -+ -+LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(random__extract_entropy, extract_entropy_user, -+ -+ random_extract_entropy_user, -+ -+ TP_PROTO(int nbytes, int entropy_count, unsigned long IP), -+ -+ TP_ARGS(nbytes, entropy_count, IP) -+) -+#else - LTTNG_TRACEPOINT_EVENT_CLASS(random__extract_entropy, - TP_PROTO(const char *pool_name, int nbytes, int entropy_count, - unsigned long IP), -@@ -123,6 +201,7 @@ LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP(random__extract_entropy, extract_entropy_use - - TP_ARGS(pool_name, nbytes, entropy_count, IP) - ) -+#endif - - - --- -2.19.1 - |
