From 8723cc87982825754f314b0c18910319a3ced716 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 9 Oct 2018 14:42:49 -0400 Subject: telemetry_session: Use a std::array in GenerateTelemetryId() We don't need to potentially heap-allocate a std::string instance here, given the data is known ahead of time. We can just place it within an array and pass this to the mbedtls functions. --- src/core/telemetry_session.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'src/core') diff --git a/src/core/telemetry_session.cpp b/src/core/telemetry_session.cpp index f29fff1e7..68edb24f5 100644 --- a/src/core/telemetry_session.cpp +++ b/src/core/telemetry_session.cpp @@ -2,6 +2,8 @@ // Licensed under GPLv2 or any later version // Refer to the license.txt file included. +#include + #include "common/assert.h" #include "common/common_types.h" #include "common/file_util.h" @@ -28,11 +30,11 @@ static u64 GenerateTelemetryId() { mbedtls_entropy_context entropy; mbedtls_entropy_init(&entropy); mbedtls_ctr_drbg_context ctr_drbg; - std::string personalization = "yuzu Telemetry ID"; + constexpr std::array personalization{{"yuzu Telemetry ID"}}; mbedtls_ctr_drbg_init(&ctr_drbg); ASSERT(mbedtls_ctr_drbg_seed(&ctr_drbg, mbedtls_entropy_func, &entropy, - reinterpret_cast(personalization.c_str()), + reinterpret_cast(personalization.data()), personalization.size()) == 0); ASSERT(mbedtls_ctr_drbg_random(&ctr_drbg, reinterpret_cast(&telemetry_id), sizeof(u64)) == 0); -- cgit v1.2.3
