* buildroot: add options to build the kernel for NFS bootFlorian Fainelli2016-02-011-0/+34
| | | | | | | | | Add the basic set of kernel options to allow it from mounting a NFS root and boot from it. Signed-off-by: Florian Fainelli <florian@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@48590 3c298f89-4303-0410-b956-a3cf2f4a3e73
* include/kernel: add custom USER/DOMAIN config optionsFelix Fietkau2016-01-281-0/+16
| | | | | | | | | | | | | | | These allow the generated kernel's build metadata to be defined explicitly. This metadata is reported, eg, at boot time and in `uname -a` on running systems. If the variables aren't configured, the current build system username and hostname are used as normal. The motivation for this option is to achive reproducible (bit-for-bit identical) kernel builds of official openwrt releases.

* Configure IPv6 kernel options in config/Config-kernel.inFelix Fietkau2016-01-041-0/+23
| | | | | | | | | | | | | | | | | | | Revision 46834 changed IPv6 support from a module to builtin. But since the configuration of the IPv6 kernel options was left in package/kernel/linux/modules/netsupport.mk, this means that an empty kmod-ipv6 module was still being generated (not packaged). This patch moves the configuration of the IPv6 kernel options to config/Config-kernel.in to remove this last bit of the module. Note that CONFIG_IPV6_PRIVACY was dropped (enabled by default since Linux v3.13), so this option is no longer needed.

* build: disable kernel stack protector support for i386/x86_64Felix Fietkau2015-08-021-0/+1
| | | | | | | | | | | | When stack protector support is disabled in libc (always the case for !musl), gcc assumes that it needs to use __stack_chk_guard for the stack canary. This causes kernel build errors, because the kernel is only set up to handle TLS stack canaries.

| | | | | | | | | | | Make musl provide libssp_nonshared.a and make GCC link it unconditionally if musl is used. This should be a no-op if SSP is disabled and seems to be the only reliable way of dealing with SSP over all packages due to the mess that is linkerflags handling in packages.

* Support for building an hardened OpenWRTJohn Crispin2015-01-171-9/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce configuration options to build an "hardened" OpenWRT. Options to enable Stack-Smashing Protection, FORTIFY_SOURCE and RELRO have been introduced. uClibc makefile now automatically detects if SSP support is necessary. hostapd makefile has been fixed to use "^" as sed separator since using a comma was problematic when using "-Wl,-z,now" and the like in TARGET_CFLAGS. Currently enabling SSP on user space depends on enabling SSP kernel side, this is due to the fact that TARGET_CFLAGS are used to build kernel modules (at least). Suggestions on how to avoid this are welcome. Using "select" instead of "depends on" doesn't seem to work with choice entries. Tested with a lantiq (WBMR) router, GCC 4.8, uClibc and a subset of the available packages. Needs to be tested with GCC 4.9 and the remaining packages. PIE not currently included.
