* The top level function run_all_tests() executes tests for all of the + * supported instruction sets: ARM, 16-bit Thumb, and 32-bit Thumb. These tests + * fall into two categories; run_api_tests() checks basic functionality of the + * kprobes API, and run_test_cases() is a comprehensive test for kprobes + * instruction decoding and simulation. + * + * run_test_cases() first checks the kprobes decoding table for self consistency + * (using table_test()) then executes a series of test cases for each of the CPU + * instruction forms. coverage_start() and coverage_end() are used to verify + * that these test cases cover all of the possible combinations of instructions + * described by the kprobes decoding tables. + * + * The individual test cases are in kprobes-test-arm.c and kprobes-test-thumb.c + * which use the macros defined in kprobes-test.h. The rest of this + * documentation will describe the operation of the framework used by these + * test cases. + */ + +/* + * TESTING METHODOLOGY + * ------------------- + * + * The methodology used to test an ARM instruction 'test_insn' is to use + * inline assembler like: + * + * test_before: nop + * test_case: test_insn + * test_after: nop + * + * When the test case is run a kprobe is placed of each nop. The + * post-handler of the test_before probe is used to modify the saved CPU + * register context to that which we require for the test case. The + * pre-handler of the of the test_after probe saves a copy of the CPU + * register context. In this way we can execute test_insn with a specific + * register context and see the results afterwards. + * + * To actually test the kprobes instruction emulation we perform the above + * step a second time but with an additional kprobe on the test_case + * instruction itself. If the emulation is accurate then the results seen + * by the test_after probe will be identical to the first run which didn't + * have a probe on test_case. + * + * Each test case is run several times with a variety of variations in the + * flags value of stored in CPSR, and for Thumb code, different ITState. + * + * For instructions which can modify PC, a second test_after probe is used + * like this: + * + * test_before: nop + * test_case: test_insn + * test_after: nop + * b test_done + * test_after2: nop + * test_done: + * + * The test case is constructed such that test_insn branches to + * test_after2, or, if testing a conditional instruction, it may just + * continue to test_after. The probes inserted at both locations let us + * determine which happened. A similar approach is used for testing + * backwards branches... + * + * b test_before + * b test_done @ helps to cope with off by 1 branches + * test_after2: nop + * b test_done + * test_before: nop + * test_case: test_insn + * test_after: nop + * test_done: + * + * The macros used to generate the assembler instructions describe above + * are TEST_INSTRUCTION, TEST_BRANCH_F (branch forwards) and TEST_BRANCH_B + * (branch backwards). In these, the local variables numbered 1, 50, 2 and + * 99 represent: test_before, test_case, test_after2 and test_done. + * + * FRAMEWORK + * --------- + * + * Each test case is wrapped between the pair of macros TESTCASE_START and + * TESTCASE_END. As well as performing the inline assembler boilerplate, + * these call out to the kprobes_test_case_start() and + * kprobes_test_case_end() functions which drive the execution of the test + * case. The specific arguments to use for each test case are stored as + * inline data constructed using the various TEST_ARG_* macros. Putting + * this all together, a simple test case may look like: + * + * TESTCASE_START("Testing mov r0, r7") + * TEST_ARG_REG(7, 0x12345678) // Set r7=0x12345678 + * TEST_ARG_END("") + * TEST_INSTRUCTION("mov r0, r7") + * TESTCASE_END + * + * Note, in practice the single convenience macro TEST_R would be used for this + * instead. + * + * The above would expand to assembler looking something like: + * + * @ TESTCASE_START + * bl __kprobes_test_case_start + * @ start of inline data... + * .ascii "mov r0, r7" @ text title for test case + * .byte 0 + * .align 2 + * + * @ TEST_ARG_REG + * .byte ARG_TYPE_REG + * .byte 7 + * .short 0 + * .word 0x1234567 + * + * @ TEST_ARG_END + * .byte ARG_TYPE_END + * .byte TEST_ISA @ flags, including ISA being tested + * .short 50f-0f @ offset of 'test_before' + * .short 2f-0f @ offset of 'test_after2' (if relevent) + * .short 99f-0f @ offset of 'test_done' + * @ start of test case code... + * 0: + * .code TEST_ISA @ switch to ISA being tested + * + * @ TEST_INSTRUCTION + * 50: nop @ location for 'test_before' probe + * 1: mov r0, r7 @ the test case instruction 'test_insn' + * nop @ location for 'test_after' probe + * + * // TESTCASE_END + * 2: + * 99: bl __kprobes_test_case_end_##TEST_ISA + * .code NONMAL_ISA + * + * When the above is execute the following happens... + * + * __kprobes_test_case_start() is an assembler wrapper which sets up space + * for a stack buffer and calls the C function kprobes_test_case_start(). + * This C function will do some initial processing of the inline data and + * setup some global state. It then inserts the test_before and test_after + * kprobes and returns a value which causes the assembler wrapper to jump + * to the start of the test case code, (local label '0'). + * + * When the test case code executes, the test_before probe will be hit and + * test_before_post_handler will call setup_test_context(). This fills the + * stack buffer and CPU registers with a test pattern and then processes + * the test case arguments. In our example there is one TEST_ARG_REG which + * indicates that R7 should be loaded with the value 0x12345678. + * + * When the test_before probe ends, the test case continues and executes + * the "mov r0, r7" instruction. It then hits the test_after probe and the + * pre-handler for this (test_after_pre_handler) will save a copy of the + * CPU register context. This should now have R0 holding the same value as + * R7. + * + * Finally we get to the call to __kprobes_test_case_end_{32,16}. This is + * an assembler wrapper which switches back to the ISA used by the test + * code and calls the C function kprobes_test_case_end(). + * + * For each run through the test case, test_case_run_count is incremented + * by one. For even runs, kprobes_test_case_end() saves a copy of the + * register and stack buffer contents from the test case just run. It then + * inserts a kprobe on the test case instruction 'test_insn' and returns a + * value to cause the test case code to be re-run. + * + * For odd numbered runs, kprobes_test_case_end() compares the register and + * stack buffer contents to those that were saved on the previous even + * numbered run (the one without the kprobe on test_insn). These should be + * the same if the kprobe instruction simulation routine is correct. + * + * The pair of test case runs is repeated with different combinations of + * flag values in CPSR and, for Thumb, different ITState. This is + * controlled by test_context_cpsr(). + * + * BUILDING TEST CASES + * ------------------- + * + * + * As an aid to building test cases, the stack buffer is initialised with + * some special values: + * + * [SP+13*4] Contains SP+120.
