Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: sun6i: reduce DMA RX transfer width to single byte<br /> <br /> Through empirical testing it has been determined that sometimes RX SPI<br /> transfers with DMA enabled return corrupted data. This is down to single<br /> or even multiple bytes lost during DMA transfer from SPI peripheral to<br /> memory. It seems the RX FIFO within the SPI peripheral can become<br /> confused when performing bus read accesses wider than a single byte to it<br /> during an active SPI transfer.<br /> <br /> This patch reduces the width of individual DMA read accesses to the<br /> RX FIFO to a single byte to mitigate that issue.
