xilinx: Fix compiler warning

2017-11-11T13:33:51Z

commit 9f8b93cb32e088d3377c86fabb666b884bac0f12 upstream. The time comparsion functions require arguments of type unsigned long instead of (signed) long. Signed-off-by: Manuel Schölling Signed-off-by: David S. Miller Signed-off-by: Arnd Bergmann Signed-off-by: Ben Hutchings

net: xilinx_emaclite: fix freezes due to unordered I/O

2017-03-16T02:27:14Z

commit acf138f1b00bdd1b7cd9894562ed0c2a1670888e upstream. The xilinx_emaclite uses __raw_writel and __raw_readl for register accesses. Those functions do not imply any kind of memory barriers and they may be reordered. The driver does not seem to take that into account, though, and the driver does not satisfy the ordering requirements of the hardware. For clear examples, see xemaclite_mdio_write() and xemaclite_mdio_read() which try to set MDIO address before initiating the transaction. I'm seeing system freezes with the driver with GCC 5.4 and current Linux kernels on Zynq-7000 SoC immediately when trying to use the interface. In commit 123c1407af87 ("net: emaclite: Do not use microblaze and ppc IO functions") the driver was switched from non-generic in_be32/out_be32 (memory barriers, big endian) to __raw_readl/__raw_writel (no memory barriers, native endian), so apparently the device follows system endianness and the driver was originally written with the assumption of memory barriers. Rather than try to hunt for each case of missing barrier, just switch the driver to use iowrite32/ioread32/iowrite32be/ioread32be depending on endianness instead. Tested on little-endian Zynq-7000 ARM SoC FPGA. Signed-off-by: Anssi Hannula Fixes: 123c1407af87 ("net: emaclite: Do not use microblaze and ppc IO functions") Signed-off-by: David S.

net: xilinx_emaclite: fix receive buffer overflow

2017-03-16T02:27:14Z

commit cd224553641848dd17800fe559e4ff5d208553e8 upstream. xilinx_emaclite looks at the received data to try to determine the Ethernet packet length but does not properly clamp it if proto_type == ETH_P_IP or 1500 < proto_type <= 1518, causing a buffer overflow and a panic via skb_panic() as the length exceeds the allocated skb size. Fix those cases. Also add an additional unconditional check with WARN_ON() at the end.

xilinx: Use time_before_eq()

2014-05-22T19:50:13Z

To be future-proof and for better readability the time comparisons are modified to use time_before_eq() instead of plain, error-prone math. Signed-off-by: Manuel Schölling Signed-off-by: David S. Miller

net: emaclite: remove empty MDIO bus reset function

2014-03-28T05:38:02Z

xemaclite_mdio_reset() does nothing useful and is optional for the MDIO bus code, so let's just remove it. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

xilinx_emaclite: Call dev_consume_skb_any instead of dev_kfree_skb.

2014-03-25T04:19:22Z

Replace dev_kfree_skb with dev_consume_skb_any in xemaclite_send which can be called in hard irq and other contexts. xemacelite_send only frees skbs that it has successfully transmitted. Signed-off-by: "Eric W. Biederman"

xilinx: Convert uses of __constant_ to

2014-03-12T19:28:06Z

The use of __constant_ has been unnecessary for quite awhile now. Make these uses consistent with the rest of the kernel. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

drivers/net: delete non-required instances of include

2014-01-16T19:53:26Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. This covers everything under drivers/net except for wireless, which has been submitted separately. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller
