From b3f95490b9bec020314eb32016988ee262d52884 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 29 Oct 2017 19:32:10 +0100 Subject: kernel: generic: Add kernel 4.14 support 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 --- ...er.h-prevent-redefinition-of-struct-ethhd.patch | 65 ++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 target/linux/generic/pending-4.14/272-uapi-if_ether.h-prevent-redefinition-of-struct-ethhd.patch (limited to 'target/linux/generic/pending-4.14/272-uapi-if_ether.h-prevent-redefinition-of-struct-ethhd.patch') diff --git a/target/linux/generic/pending-4.14/272-uapi-if_ether.h-prevent-redefinition-of-struct-ethhd.patch b/target/linux/generic/pending-4.14/272-uapi-if_ether.h-prevent-redefinition-of-struct-ethhd.patch new file mode 100644 index 0000000000..1dca07328d --- /dev/null +++ b/target/linux/generic/pending-4.14/272-uapi-if_ether.h-prevent-redefinition-of-struct-ethhd.patch @@ -0,0 +1,65 @@ +From: David Heidelberger +Subject: uapi/if_ether.h: prevent redefinition of struct ethhdr + +Musl provides its own ethhdr struct definition.
