glsl: free or reuse memory allocated for TF varying
When a shader program is de-serialized the gl_shader_program passed in may actually still hold memory allocations for the transform feedback varyings. If that is the case, free the varying names and reallocate the new storage for the names array. This fixes a memory leak: Direct leak of 48 byte(s) in 6 object(s) allocated from: in malloc (/usr/lib64/gcc/x86_64-pc-linux-gnu/7.3.0/libasan.so+0xdb880) in transform_feedback_varyings ../../samba/mesa/src/mesa/main/transformfeedback.c:875 in _mesa_TransformFeedbackVaryings ../../samba/mesa/src/mesa/main/transformfeedback.c:985 ... Indirect leak of 42 byte(s) in 6 object(s) allocated from: in __interceptor_strdup (/usr/lib64/gcc/x86_64-pc-linux-gnu/7.3.0/libasan.so+0x761c8) in transform_feedback_varyings ../../samba/mesa/src/mesa/main/transformfeedback.c:887 in _mesa_TransformFeedbackVaryings ../../samba/mesa/src/mesa/main/transformfeedback.c:985 Fixes: ab2643e4b06f63c93a57624003679903442634a8 glsl: serialize data from glTransformFeedbackVaryings Signed-off-by: Gert Wollny <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>
