[PATCH 1/2] mtd: docg3: don't set conflicting BCH_CONST_PARAMS option

by Arnd Bergmann

I noticed during the creation of another bugfix that the BCH_CONST_PARAMS option that is set by DOCG3 breaks setting variable parameters for any other users of the BCH library code. The only other user we have today is the MTD_NAND software BCH implementation (most flash controllers use hardware BCH these days and are not affected). I considered removing BCH_CONST_PARAMS entirely because of the inherent conflict, but according to the description in lib/bch.c there is a significant performance benefit in keeping it. To avoid the immediate problem of the conflict between MTD_NAND_BCH and DOCG3, this only sets the constant parameters if MTD_NAND_BCH is disabled, which should fix the problem for all cases that are affected. This should also work for all stable kernels. Note that there is only one machine that actually seems to use the DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have the driver disabled, but it almost certainly shows up if we wanted to test random kernels on machines that use software BCH in MTD.

[PATCH v6] selinux: policydb - fix byte order and alignment issues

by Ondrej Mosnacek

Do the LE conversions before doing the Infiniband-related range checks. The incorrect checks are otherwise causing a failure to load any policy with an ibendportcon rule on BE systems. This can be reproduced by running (on e.g. ppc64): cat >my_module.cil <<EOF (type test_ibendport_t) (roletype object_r test_ibendport_t) (ibendportcon mlx4_0 1 (system_u object_r test_ibendport_t ((s0) (s0)))) EOF semodule -i my_module.cil Also, fix loading/storing the 64-bit subnet prefix for OCON_IBPKEY to use a correctly aligned buffer. Finally, do not use the 'nodebuf' (u32) buffer where 'buf' (__le32) should be used instead. Tested internally on a ppc64 machine with a RHEL 7 kernel with this patch applied.
