Vladimir Oltean authored
When the driver is working in TCFQ/EOQ mode (i.e. interacts with the SPI controller's FIFOs directly) the following sequence of operations happens: - The first byte of the tx buffer gets pushed to the TX FIFO (dspi->len gets decremented). This triggers the train of interrupts that handle the rest of the bytes. - The dspi_interrupt handles a TX confirmation event. It reads the newly available byte from the RX FIFO, checks the dspi->len exit condition, and if there's more to be done, it kicks off the next interrupt in the train by writing the next byte to the TX FIFO. Now the problem is that the wait queue is woken up one byte too early, because dspi->len becomes 0 as soon as the byte has been pushed into the TX FIFO. Its interrupt has not yet been processed and the RX byte has not been put from the FIFO into the buffer. Depending on the timing of the wait queue wakeup vs the handling of the last dspi_interrupt, it can happen that the main SPI message pump thread has already returned back into the spi_device driver. When the rx buffer is on stack (which it can be, because in this mode, the DSPI doesn't do DMA), the last interrupt will perform a memory write into an rx buffer that has been freed. This manifests as stack corruption. The solution is to only wake up the wait queue when dspi_rxtx says so, i.e. after it has processed the last TX confirmation interrupt and collected the last RX byte.

The actual device name of the SPI controller being registered on EP93xx is "spi0" (as seen by gpiod_find_lookup_table()). This patch fixes all relevant lookup tables and the following failure (seen on EDB9302): ep93xx-spi ep93xx-spi.0: failed to register SPI master ep93xx-spi: probe of ep93xx-spi.0 failed with error -22 Fixes: 1dfbf334 ("spi: ep93xx: Convert to use CS GPIO descriptors") Cc: stable@vger.kernel.org Signed-off-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Lukasz Majewski <lukma@denx.de> Link: https://lore.kernel.org/r/20190831180402.10008-1-alexander.sverdlin@gmail.comSigned-off-by: Mark Brown <broonie@kernel.org>
