From 40eb0286be6f0d2964dad8327e440229da92156f Mon Sep 17 00:00:00 2001 From: Joseph Hickey Date: Tue, 28 May 2024 13:17:18 -0400 Subject: [PATCH] Fix #1463, Implement separate allocator for task stacks Removes default use of malloc() for creating a task stack in VxWorks. Replace with a mempool-based solution, that can also be replaced with some other memory pool based on user preferences. --- src/os/vxworks/CMakeLists.txt | 5 + src/os/vxworks/inc/os-impl-tasks.h | 7 +- src/os/vxworks/inc/os-impl-taskstack.h | 72 +++++++ src/os/vxworks/src/os-impl-tasks.c | 91 ++------- .../vxworks/src/os-impl-taskstack-default.c | 191 ++++++++++++++++++ .../ut-stubs/CMakeLists.txt | 1 + .../ut-stubs/inc/OCS_memPartLib.h | 26 +++ .../ut-stubs/override_inc/memPartLib.h | 13 +- .../src/vxworks-memPartLib-handlers.c | 49 +++++ .../ut-stubs/src/vxworks-memPartLib-stubs.c | 141 ++++++++++++- src/unit-test-coverage/vxworks/CMakeLists.txt | 1 + .../vxworks/src/coveragetest-tasks.c | 50 ++--- .../src/coveragetest-taskstack-default.c | 134 ++++++++++++ .../vxworks/ut-stubs/CMakeLists.txt | 5 +- .../ut-stubs/src/os-impl-taskstack-handlers.c | 73 +++++++ .../ut-stubs/src/os-impl-taskstack-stubs.c | 72 +++++++ 16 files changed, 811 insertions(+), 120 deletions(-) create mode 100644 src/os/vxworks/inc/os-impl-taskstack.h create mode 100644 src/os/vxworks/src/os-impl-taskstack-default.c create mode 100644 src/unit-test-coverage/ut-stubs/src/vxworks-memPartLib-handlers.c create mode 100644 src/unit-test-coverage/vxworks/src/coveragetest-taskstack-default.c create mode 100644 src/unit-test-coverage/vxworks/ut-stubs/src/os-impl-taskstack-handlers.c create mode 100644 src/unit-test-coverage/vxworks/ut-stubs/src/os-impl-taskstack-stubs.c diff --git a/src/os/vxworks/CMakeLists.txt b/src/os/vxworks/CMakeLists.txt index 5bcc7f4d3..c149a7d70 100644 --- a/src/os/vxworks/CMakeLists.txt +++ b/src/os/vxworks/CMakeLists.txt @@ -74,6 +74,11 @@ else() ) endif () +# User-selectable mempool impl for task stack blocks +list(APPEND VXWORKS_IMPL_SRCLIST + src/os-impl-taskstack-default.c +) + # Defines an OBJECT target named "osal_vxworks_impl" with selected source files add_library(osal_vxworks_impl OBJECT ${VXWORKS_BASE_SRCLIST} diff --git a/src/os/vxworks/inc/os-impl-tasks.h b/src/os/vxworks/inc/os-impl-tasks.h index aab87482b..2c49a3d32 100644 --- a/src/os/vxworks/inc/os-impl-tasks.h +++ b/src/os/vxworks/inc/os-impl-tasks.h @@ -27,6 +27,7 @@ #define OS_IMPL_TASKS_H #include "osconfig.h" +#include "os-impl-taskstack.h" #include #if defined(VX_WIND_TCB_SIZE) @@ -42,12 +43,12 @@ typedef WIND_TCB OS_VxWorks_TCB_t; #endif /* !defined(VX_WIND_TCB_SIZE) */ /*tasks */ -typedef struct +typedef struct OS_impl_task_internal_record { OS_VxWorks_TCB_t tcb; /* Must be first */ TASK_ID vxid; - void * heap_block; /* set non-null if the stack was obtained with malloc() */ - size_t heap_block_size; + + OS_impl_task_stack_mblock_t stack; } OS_impl_task_internal_record_t; /* Tables where the OS object information is stored */ diff --git a/src/os/vxworks/inc/os-impl-taskstack.h b/src/os/vxworks/inc/os-impl-taskstack.h new file mode 100644 index 000000000..eecc74fda --- /dev/null +++ b/src/os/vxworks/inc/os-impl-taskstack.h @@ -0,0 +1,72 @@ +/************************************************************************ + * NASA Docket No. GSC-18,719-1, and identified as “core Flight System: Bootes” + * + * Copyright (c) 2020 United States Government as represented by the + * Administrator of the National Aeronautics and Space Administration. + * All Rights Reserved. + * + * Licensed under the Apache License, Version 2.0 (the "License"); you may + * not use this file except in compliance with the License.
