Hi, I met some trouble to compile somes packages and after having a look from the logs, i noticed that the "gcc" is not unknown : >>> Configuring source in /var/tmp/portage/sys-devel/llvm-11.1.0/work/llvm ... * abi_x86_64.amd64: running multilib-minimal_abi_src_configure ccache: error: Could not find compiler "x86_64-pc-linux-gnu-g++" in PATH ccache: error: Could not find compiler "x86_64-pc-linux-gnu-gcc" in PATH * Working in BUILD_DIR: "/var/tmp/portage/sys-devel/llvm-11.1.0/work/llvm-11.1.0_build-abi_x86_64.amd64" cmake -C /var/tmp/portage/sys-devel/llvm-11.1.0/work/llvm-11.1.0_build-abi_x86_64.amd64/gentoo_common_config.cmake -G Ninja -DCMAKE_INSTALL_PREFIX=/usr -DLLVM_APPEND_VC_REV=OFF -DCMAKE_INSTALL_PREFIX=/usr/lib/llvm/11 -DLLVM_LIBDIR_SUFFIX=6 4 -DBUILD_SHARED_LIBS=OFF -DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON -DLLVM_DISTRIBUTION_COMPONENTS=LLVM;LTO;Remarks;llvm-config;cmake-exports;llvm-headers;LLVMDemangle;LLVMSupport;LLVMTableGen;llvm-tblgen;FileCheck;llvm-PerfectS huffle;count;not;yaml-bench;bugpoint;dsymutil;llc;lli;lli-child-target;llvm-addr2line;llvm-ar;llvm-as;llvm-bcanalyzer;llvm-c-test;llvm-cat;llvm-cfi-verify;llvm-config;llvm-cov;llvm-cvtres;llvm-cxxdump;llvm-cxxfilt;llvm-cxxmap;llvm-diff;llv m-dis;llvm-dlltool;llvm-dwarfdump;llvm-dwp;llvm-elfabi;llvm-exegesis;llvm-extract;llvm-gsymutil;llvm-ifs;llvm-install-name-tool;llvm-jitlink;llvm-lib;llvm-link;llvm-lipo;llvm-lto;llvm-lto2;llvm-mc;llvm-mca;llvm-ml;llvm-modextract;llvm-mt;l lvm-nm;llvm-objcopy;llvm-objdump;llvm-opt-report;llvm-pdbutil;llvm-profdata;llvm-ranlib;llvm-rc;llvm-readelf;llvm-readobj;llvm-reduce;llvm-rtdyld;llvm-size;llvm-split;llvm-stress;llvm-strings;llvm-strip;llvm-symbolizer;llvm-undname;llvm-xr ay;obj2yaml;opt;sancov;sanstats;verify-uselistorder;yaml2obj;opt-viewer; -DLLVM_TARGETS_TO_BUILD= -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=X86;NVPTX;BPF;AMDGPU -DLLVM_BUILD_TESTS=no -DLLVM_ENABLE_FFI=yes -DLLVM_ENABLE_LIBEDIT=no -DLLVM_ENABLE_ TERMINFO=yes -DLLVM_ENABLE_LIBXML2=yes -DLLVM_ENABLE_ASSERTIONS=no -DLLVM_ENABLE_LIBPFM=no -DLLVM_ENABLE_EH=ON -DLLVM_ENABLE_RTTI=ON -DLLVM_ENABLE_Z3_SOLVER=no -DLLVM_HOST_TRIPLE=x86_64-pc-linux-gnu -DFFI_INCLUDE_DIR=/usr/lib64/libffi/incl ude -DFFI_LIBRARY_DIR= -DHAVE_LIBXAR=0 -DPython3_EXECUTABLE=/usr/bin/python3.9 -DOCAMLFIND=NO -DGO_EXECUTABLE=GO_EXECUTABLE-NOTFOUND -DLLVM_BUILD_DOCS=OFF -DLLVM_ENABLE_OCAMLDOC=OFF -DLLVM_ENABLE_SPHINX=OFF -DLLVM_ENABLE_DOXYGEN=OFF -DLLVM _INSTALL_UTILS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_TOOLCHAIN_FILE=/var/tmp/portage/sys-devel/llvm-11.1.0/work/llvm-11.1.0_build-abi_x86_64.amd64/gentoo_toolchain.cmake /var/tmp/portage/sys-devel/llvm-11.1.0/work/llvm loading initial cache file /var/tmp/portage/sys-devel/llvm-11.1.0/work/llvm-11.1.0_build-abi_x86_64.amd64/gentoo_common_config.cmake -- The C compiler identification is unknown -- The CXX compiler identification is unknown -- The ASM compiler identification is unknown -- Found assembler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-gcc -- Detecting C compiler ABI info -- Detecting C compiler ABI info - failed -- Check for working C compiler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-gcc -- Check for working C compiler: /usr/lib/ccache/bin/x86_64-pc-linux-gnu-gcc - broken CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:66 (message): The C compiler "/usr/lib/ccache/bin/x86_64-pc-linux-gnu-gcc" Then, i tried to choose again the gcc in the list : > eselect gcc list [1] x86_64-pc-linux-gnu-10.2.0 * But it met some trouble to link e.g. : > mv: cannot move '/usr/bin/.gcc.config.x86_64-pc-linux-gnu-c++' to '/usr/bin/x86_64-pc-linux-gnu-c++': Permission denied > mv: cannot move '/usr/bin/.gcc.config.x86_64-pc-linux-gnu-cpp' to '/usr/bin/x86_64-pc-linux-gnu-cpp': Permission denied > mv: cannot move '/usr/bin/.gcc.config.x86_64-pc-linux-gnu-g++' to '/usr/bin/x86_64-pc-linux-gnu-g++': Permission denied > mv: cannot move '/usr/bin/.gcc.config.x86_64-pc-linux-gnu-gcc' to '/usr/bin/x86_64-pc-linux-gnu-gcc': Permission denied It is the first time that i meet this error.

I fixed this in https://github.com/perfinion/hardened-refpolicy/pull/20
Hi, Thank you for your work. To reproduce this : I removed my previous rules : # impossible to do "eselect gcc set" #============= gcc_config_t ============== allow gcc_config_t bin_t:lnk_file create; allow gcc_config_t lib_t:lnk_file create; allow gcc_config_t self:capability dac_read_search; allow gcc_config_t self:process getsched; allow gcc_config_t tmpfs_t:filesystem getattr; allow gcc_config_t bin_t:lnk_file { rename unlink }; allow gcc_config_t lib_t:lnk_file { rename unlink }; And i gave a try to compile again sys-process/htop and sys-devel/llvm. There is no errors. :-) But i noticed this behaviour : > eselect gcc list [1] x86_64-pc-linux-gnu-10.3.0 * > eselect gcc set 1 * gcc-config: need write access to / Hmm... What do you think about this ? > mount /dev/mapper/gnu-rootfs on / type btrfs (rw,noatime,seclabel,compress=lzo,ssd,discard,space_cache,autodefrag,subvolid=257,subvol=/@) Peace.
My apologies : > eselect gcc set 1 * gcc-config: need write access to / With or without my rules, i get the same message when i am in Enforcing mode.
I'd like to have your return before closing this bug.
We fixed the ${EROOT} writability check in bug 823203 but looks like we still need to fix the symlink part?
The policy parts of this were added in 2.20210908-r1
