This adds initial support for kernel 4.14 based on the patches for kernel 4.9. In the configuration I deactivated some of the new possible security features like: CONFIG_REFCOUNT_FULL CONFIG_SLAB_FREELIST_HARDENED CONFIG_SOFTLOCKUP_DETECTOR CONFIG_WARN_ALL_UNSEEDED_RANDOM And these overlay FS options are also deactivated: CONFIG_OVERLAY_FS_INDEX CONFIG_OVERLAY_FS_REDIRECT_DIR I activated this: CONFIG_FORTIFY_SOURCE CONFIG_POSIX_TIMERS CONFIG_SLAB_MERGE_DEFAULT CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED I am not sure if I did the porting correct for the following patches: target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch target/linux/generic/hack-4.14/220-gc_sections.patch target/linux/generic/hack-4.14/321-powerpc_crtsavres_prereq.patch target/linux/generic/pending-4.14/305-mips_module_reloc.patch target/linux/generic/pending-4.14/611-netfilter_match_bypass_default_table.patch target/linux/generic/pending-4.14/680-NET-skip-GRO-for-foreign-MAC-addresses.patch Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Subject: uapi/if_ether.h: prevent redefinition of struct ethhdr
|
|
|
|
Musl provides its own ethhdr struct definition. Add a guard to prevent
|
|
its definition of the appropriate musl header has already been included.
