I'm working on collecting this information in a more general way. It is complicated by the fact that there are some functions that have the same names but different behaviors, and I want to be clear about when that is an issue. There are nevertheless limits to the accuracy that can be obtained with Coccinelle, because Coccinelle doesn't take values into account. Sometimes a variable is initialized to NULL, just to have a starting value, but in practice the only way to reach an error return is via conditionals that have the effect of ensuring that the value is ERR_PTR. So at least the cases that are reported as being able to return both NULL and ERR_PTR will need some careful checking. julia > > There is one problem with your patch: > > > drivers/tty/serial/sirfsoc_uart.c | 2 +- > > 1 file changed, 1 insertion(+), 1 deletion(-) > > > > diff --git a/drivers/tty/serial/sirfsoc_uart.c b/drivers/tty/serial/sirfsoc_uart.c > > index b186c9c4f850..666ca3156961 100644 > > --- a/drivers/tty/serial/sirfsoc_uart.c > > +++ b/drivers/tty/serial/sirfsoc_uart.c > > @@ -609,7 +609,7 @@ static void sirfsoc_uart_start_next_rx_dma(struct uart_port *port) > > sirfport->rx_dma_items.dma_addr, SIRFSOC_RX_DMA_BUF_SIZE, > > SIRFSOC_RX_DMA_BUF_SIZE / 2, > > DMA_DEV_TO_MEM, DMA_PREP_INTERRUPT); > > - if (IS_ERR_OR_NULL(sirfport->rx_dma_items.desc)) { > > + if (!sirfport->rx_dma_items.desc) { > > dev_err(port->dev, "DMA slave single fail\n"); > > return; > > } > > The serial driver is for the sirf platform, which uses the sirf-dma > dmaengine driver, and that particular driver has an incorrect > dma_prep_cyclic implementation, so I think we also need this fix: > > diff --git a/drivers/dma/sirf-dma.c b/drivers/dma/sirf-dma.c > index 8f62edad51be..220c611c89ae 100644 > --- a/drivers/dma/sirf-dma.c > +++ b/drivers/dma/sirf-dma.c > @@ -775,7 +775,7 @@ sirfsoc_dma_prep_cyclic(struct dma_chan *chan, dma_addr_t addr, > * BUFB > */ > if (buf_len != 2 * period_len) > - return ERR_PTR(-EINVAL); > + return NULL; > > /* Get free descriptor */ > spin_lock_irqsave(&schan->lock, iflags); > > > Arnd > -- > To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > ^ permalink raw reply [flat|nested] 6+ messages in thread

Hi, You can have an idea of the strategy used in this post: https://lkml.org/lkml/2016/11/1/388 Julia is currently working on a more complete strategy in order to find such issues. In the meantime, if you want, I can send the coccinelle scripts used.
