Summary: The GLX 1.3 protocol packing for glXDestroyPbuffer not 8
bytes
Product: Mesa
Version: 6.5
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: GLX
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]

The GLX 1.3 protocol packing for glXDestroyPbuffer should have a
length of 8 bytes:
1 CARD8 opcode (X assigned)
1 28 GLX opcode (glXDestroyPbuffer)
2 2 request length
4 GLX_PBUFFER glx_pbuffer
Mesa's request data structure has the correct size:
typedef struct GLXDestroyPbuffer {
CARD8 reqType;
CARD8 glxCode;
CARD16 length ;
CARD32 pbuffer ;
} xGLXDestroyPbufferReq;
however, the implementation of DestroyPbuffer:
Mesa-6.5.3/src/glx/x11/glx_pbuffer.c:DestroyPbuffer()
uses GetReqExtra:
GetReqExtra( GLXDestroyPbuffer, 4, req );
which gets the size of the request (8 bytes), plus an extra 4
bytes. This causes a bad length error when Mesa's libGL sends
a DestroyPbuffer request to NVIDIA's GLX implementation. Mesa's
DestroyPbuffer implementation should instead use GetReq:
GetReq( GLXDestroyPbuffer, req );
to create a request of the correct length.
