Author: Nicolai Hähnle <[email protected]> Date: Tue Oct 10 13:58:46 2017 +0200 st/mesa: don't clobber glGetInternalformat* buffer for GL_NUM_SAMPLE_COUNTS Applications might pass in a buffer that is sized too large and rely on the extra space of the buffer not being overwritten. Fixes dEQP-GLES31.functional.state_query.internal_format.partial_query.num_sample_counts Cc: [email protected] Reviewed-by: Marek Olšák <[email protected]> --- src/mesa/state_tracker/st_format.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/mesa/state_tracker/st_format.c b/src/mesa/state_tracker/st_format.c index 5e38fe5689..65be09cbde 100644 --- a/src/mesa/state_tracker/st_format.c +++ b/src/mesa/state_tracker/st_format.c @@ -2378,9 +2378,10 @@ st_QueryInternalFormat(struct gl_context *ctx, GLenum target, break; case GL_NUM_SAMPLE_COUNTS: { + int samples[16]; size_t num_samples; num_samples = st_QuerySamplesForFormat(ctx, target, internalFormat, - params); + samples); params[0] = (GLint) num_samples; break; } _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
