      Support for building an hardened OpenWRT · 491f3fc0
      John Crispin authored 
      
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.

      gcc: don't clobber stamp-bits with a symlink to itself · 548d9a00
      Felix Fietkau authored 
      
Several versions of gcc have an issue in libstdc++v3 where the build may
clobber stamp-bits with a link to itself.  This doesn't manifest itself
on all systems.  On several Ubuntu systems, this doesn't appear to be a
problem, but it is an issue on Fedora 16 systems.

To fix the issue, we'll simply filter out stamp-bits from the symlinks
to be generated.

Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
there.

      toolchain: uClibc: fix compile with full language support enabled (fixes #13095) · 309cdd61
      Felix Fietkau authored 
      When building with CONFIG_BUILD_NLS=y, uClibc fails to compile with following
message (or similar, according to https://dev.openwrt.org/ticket/13095

):

This seems to also depend on the host system used, e.g. running a fresh
checkout on a Debian 7.6 system triggered this error, while running the
very same stuff on an Ubuntu 12.10 Quantal Quetzal does not trigger it.

This is the configuration I used:

-snip-
buildbot@buildbot:~/openwrt-nls.git$ scripts/diffconfig.sh
CONFIG_TARGET_ar71xx=y
CONFIG_TARGET_ar71xx_generic=y
CONFIG_TARGET_ar71xx_generic_Default=y
CONFIG_DEVEL=y
CONFIG_BUILD_NLS=y
CONFIG_DOWNLOAD_FOLDER="/srv/downloads/downloads"
-snap-

In the ticket mentioned above, a patch is referenced which solves this issue.

Note, that this issue is also present on 14.07.

Without this patch, selecting "Compile with full language support"
results in the following question during build:

      musl: add getopt support for non-option arguments · d49f9039
      John Crispin authored 
      
musl libc doesn't support the GNU getopt extension to parse non-option
arguments when the optstring starts with '-'.

This extension is used by some utilities, notably iptables, that
currently return with errors even with perfectly valid invocations.

The patch adds the code needed by getopt.c and getopt_long.c to
implement that extension.
