2019-07-05mtd: rawnand: sunxi: Add A23/A33 DMA support with extra MBUS configurationGravatar Miquel Raynal 1-0/+24
Allwinner NAND controllers can make use of DMA to enhance the I/O throughput thanks to ECC pipelining. DMA handling with A23/A33 NAND IP is a bit different than with the older SoCs, hence the introduction of a new compatible to handle: * the differences between register offsets, * the burst length change from 4 to minimum 8, * manage SRAM accesses through MBUS with extra configuration.

2019-07-05dmaengine: imx-sdma: remove BD_INTR for channel0Gravatar Robin Gong 1-2/+2
It is possible for an irq triggered by channel0 to be received later after clks are disabled once firmware loaded during sdma probe. If that happens then clearing them by writing to SDMA_H_INTR won't work and the kernel will hang processing infinite interrupts. Actually, don't need interrupt triggered on channel0 since it's pollling SDMA_H_STATSTOP to know channel0 done rather than interrupt in current code, just clear BD_INTR to disable channel0 interrupt to avoid the above case. This issue was brought by commit 1d069bfa3c78 ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") which didn't take care the above case. Fixes: 1d069bfa3c78 ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") Cc: stable@vger.kernel.org #5.0+ Signed-off-by: Robin Gong <yibin.gong@nxp.com> Reported-by: Sven Van Asbroeck <thesven73@gmail.com> Tested-by: Sven Van Asbroeck <thesven73@gmail.com> Reviewed-by: Michael Olbrich <m.olbrich@pengutronix.de> Signed-off-by: Vinod Koul <vkoul@kernel.org>
2019-07-05dmaengine: imx-sdma: fix use-after-free on probe error pathGravatar Sven Van Asbroeck 1-21/+27
If probe() fails anywhere beyond the point where sdma_get_firmware() is called, then a kernel oops may occur. Problematic sequence of events: 1. probe() calls sdma_get_firmware(), which schedules the firmware callback to run when firmware becomes available, using the sdma instance structure as the context 2. probe() encounters an error, which deallocates the sdma instance structure 3. firmware becomes available, firmware callback is called with deallocated sdma instance structure 4. use after free - kernel oops ! Solution: only attempt to load firmware when we're certain that probe() will succeed. This guarantees that the firmware callback's context will remain valid. Note that the remove() path is unaffected by this issue: the firmware loader will increment the driver module's use count, ensuring that the module cannot be unloaded while the firmware callback is pending or running.

The "pending" variable was a u32 but we cast it to an unsigned long pointer when we do the for_each_set_bit() loop. The problem is that on big endian 64bit systems that results in an out of bounds read.
