* grub: Remove native version of grub-efiJacob Kroon2020-06-231-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The native version of grub-efi only installs the tools /usr/bin/grub-editenv /usr/bin/grub-mkimage to sysroots-components/, but equivalent tools are already provided by grub-native, the difference on x86_64 being 4 hardwired paths in grub-mkimage (values taken from grub-native): LOCALEDIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/usr/share/locale GRUB_DATADIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/usr/share GRUB_LIBDIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/usr/lib GRUB_SYSCONFDIR = $TMPDIR/work/x86_64-linux/grub-native/2.04-r0/recipe-sysroot-native/etc If grub-native and grub-efi-native are built with the following patch --- grub-2.04.orig/configure.ac +++ grub-2.04/configure.ac @@ -1980,10 +1980,10 @@ grub_libdir="$(eval echo "$libdir")" grub_localedir="$(eval echo "$localedir")" grub_datadir="$(eval echo "$datadir")" grub_sysconfdir="$(eval echo "$sysconfdir")" -AC_DEFINE_UNQUOTED(LOCALEDIR, "$grub_localedir", [Locale dir]) -AC_DEFINE_UNQUOTED(GRUB_LIBDIR, "$grub_libdir", [Library dir]) -AC_DEFINE_UNQUOTED(GRUB_DATADIR, "$grub_datadir", [Data dir]) -AC_DEFINE_UNQUOTED(GRUB_SYSCONFDIR, "$grub_sysconfdir", [Configuration dir]) +AC_DEFINE_UNQUOTED(LOCALEDIR, "/non-existent", [Locale dir]) +AC_DEFINE_UNQUOTED(GRUB_LIBDIR, "/non-existent", [Library dir]) +AC_DEFINE_UNQUOTED(GRUB_DATADIR, "/non-existent", [Data dir]) +AC_DEFINE_UNQUOTED(GRUB_SYSCONFDIR, "/non-existent", [Configuration dir]) the produced grub-editenv/grub-mkimage binaries become binary equivalent, assuming reproducible builds is active. Since the unpatched values of LOCALEDIR/GRUB_DATADIR/GRUB_LIBDIR/GRUB_SYSCONFDIR point to directories that are not expected to exist at runtime, they can be ignored.

* security_flags: turn potential string format security issues into an errorJoshua Lock2016-05-061-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add "-Wformat -Wformat-security -Werror=format-security" to the default SECURITY_CFLAGS to catch potential security vulnerabilities due to the misuse of various string formatting functions. These flags are widely used in distributions such as Fedora and Ubuntu, however we have 15 recipes in OE-Core which fail to build with these flags included and thus the flags are removed for: - busybox - console-tools - cmake - expect - gcc - gettext - kexec-tools - leafpad - libuser - ltp - makedevs - oh-puzzles - stat - unzip - zip [YOCTO #9488] (From OE-Core rev: f335f8e744fb312b3eb599c331d08a9a6e5a8ff8) Signed-off-by: Joshua Lock <joshua.g.lock@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* security_flags.inc: Special flags are needed for RPMMark Hatle2016-03-091-0/+2
| | | | | | | | | | | | | | | | RPM interally has support to build and work with the stack protector. This is disabled by default in the RPM package, and the proper settings should be specified in the security_flags. Using the default setting of stack-protector-strong causes linking problems due to issues with libtool selecting the wrong GCC objections to link against. Falling back to the RPM values of stack-protector will permit linking to work properly, and some level of protection.

* security_flags: Add SECURITY_CFLAGS to TARGET_CC_ARCH for binutilsKhem Raj2016-02-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | libtool decides to filter out -fstack-protector-strong on its own and its documented here https://www.gnu.org/software/libtool/manual/html_node/Stripped-link-flags.html this causes linking errors when linking libbfd.so since objects (.o) are compiled using -fstack-protector-strong so they are expecting to link with libssp but the option goes missing in linker flags. With this patch the security flags are hoisted upto CC itself and libtool thankfully does not touch CC. Adding to CC also means that we can now remove it from LDFLAGS since when gcc driver is used to do linking then we have LD = CC and this option makes to linker cmdline Since CC is used without CFLAGS in configure tests, some tests fail complaining that -Olevel is not used while using _FORTIFY_SOURCE therefore added SELECTED_OPTIMIZATION to TARGET_CC_ARCH as well (From OE-Core rev: 9349f28531619a4ff15c382dacc460d61e3ec7af) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* security_flags.inc: remove obsolete workarounds for curlAndre McCurdy2016-01-191-4/+0
| | | | | | | | | | | | | | | | | | | | | | The curl configure script contains sanity checks for unexpected options being passed via CFLAGS, LDFLAGS, etc. environment variables. These sanity checks catch -Dxxx options in CFLAGS, which clashes with OE's approach of using CFLAGS to pass -D_FORTIFY_SOURCE (curl's configure script suggests, quite correctly, that -Dxxx options should be passed via CPPFLAGS instead). These sanity checks previously generated fatal errors, but have been downgraded to warnings since curl v7.32. Therefore the workaround of avoiding -D_FORTIFY_SOURCE for curl is obsolete and can be removed. https://github.com/bagder/curl/commit/5d3cbde72ece7d83c280492957a26e26ab4e5cca (From OE-Core rev: d0dfd7bf9b2d6fb269f4d9b62263fd7ccc805fde) Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
