hi folks, the file attached contains a patch to fix this bug. In cs8900a_send, the cast from data to sdata is not safe. If data is not aligned on a short boundary (even address), the 16bit read with the pointer sdata, may return an unpredictible value or raise an alignement error (depending the hardware). The bug will happen if the variable odd_byte becomes true, and the next packet has an aligned value for data. the first byte is joined with saved_data, and the pointer data becomes odd. This happens for me when running a web server. Sometimes the scatter gather given in the arguments of cs8900a_send, is composed with several buffer (most of them have an even number of bytes, but not all). -- GONZALEZ Laurent Silicomp Research Institute Tel: 04 76 41 66 98
