This patch adds a new test for VMSTATE_VBUFFER and VMSTATE_VBUFFER_ALLOC_UINT32. The added test does not cover start != 0 because it's broken and unused so our intention is to remove start altogether. Signed-off-by: Guenther Hutzl Signed-off-by: Halil Pasic Reviewed-by: Dr. David Alan Gilbert --- A proof for the brokenness of start is provided in a separate patch so it can be easily reverted or not picked (thus we separate what is intended to stay, and what is intended to go away). --- tests/test-vmstate.c | 114 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 114 insertions(+) diff --git a/tests/test-vmstate.c b/tests/test-vmstate.c index d8da26f..9a57aa0 100644 --- a/tests/test-vmstate.c +++ b/tests/test-vmstate.c @@ -475,6 +475,119 @@ static void test_load_skip(void) qemu_fclose(loading); } +/* vBuffer tests */ +#define BUF_SIZE 10 + +typedef struct TestVBuffer { + uint8_t u8_1; + int32_t buffer_size; + uint8_t *vBuffer_1; + uint32_t buffer_alloc_size; + uint8_t *vBuffer_alloc_1; + uint8_t u8_2; +} TestVBuffer; + +/* buffers padded with 0xFE at the end to easier detect overflow */ +uint8_t buf1[BUF_SIZE + 1] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 0xfe}; +uint8_t buf2[BUF_SIZE + 1] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 0xfe}; + +TestVBuffer obj_vbuffer = { + .u8_1 = 100, + .buffer_size = BUF_SIZE, + .vBuffer_1 = buf1, + .buffer_alloc_size = BUF_SIZE, + .vBuffer_alloc_1 = buf2, + .u8_2 = 200, +}; + +static const VMStateDescription vmstate_vbuffer = { + .name = "complex/vbuffer", + .version_id = 1, + .minimum_version_id = 1, + .fields = (VMStateField[]) { + VMSTATE_UINT8(u8_1, TestVBuffer), + VMSTATE_VBUFFER(vBuffer_1, TestVBuffer, 1, NULL, 0, + buffer_size), + VMSTATE_VBUFFER_ALLOC_UINT32(vBuffer_alloc_1, TestVBuffer, 1, NULL, 0, + buffer_alloc_size), + VMSTATE_UINT8(u8_2, TestVBuffer), + VMSTATE_END_OF_LIST() + } +}; + +uint8_t wire_vbuffer[] = { + /* u8_1 */ 0x64, + /* vBuffer_1 */ 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, + 0x00, + /* vBuffer_alloc_1 */ 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, + 0x00, + /* u8_2 */ 0xc8, + QEMU_VM_EOF, /* just to ensure we won't get EOF reported prematurely */ +}; + +static void obj_vbuffer_copy(void *target, void *source) +{ + /* this proc copies all struct TestVBuffer entries from source to target + except the vBuffer pointers which should already point to the correct + locations.
