this includes pam_lastlog, pam_motd, pam_mail and other similar modules. This might not be a good idea on a multi-user system but could reduce slightly the overhead on single-user non-networked systems. sys-auth/pambase:mktemp - Enable pam_mktemp module on system auth stack for session handling. This module creates a private temporary directory for the user, and sets TMP and TMPDIR accordingly. sys-auth/pambase:nullok - Enable the nullok option with the pam_unix module. This allows people to login with blank passwords. sys-auth/pambase:pam_krb5 - Enable pam_krb5 module on system auth stack, as an alternative to pam_unix. If Kerberos authentication succeeds, only pam_unix will be ignorde, and all the other modules will proceed as usual, including Gnome Keyring and other session modules. It requires sys-libs/pam as PAM implementation. sys-auth/pambase:pam_ssh - Enable pam_ssh module on system auth stack for authentication and session handling. This module will accept as password the passphrase of a private SSH key (one of ~/.ssh/id_rsa, ~/.ssh/id_dsa or ~/.ssh/identity), and will spawn an ssh-agent instance to cache the open key. sys-auth/pambase:passwdqc - Enable pam_passwdqc module on system auth stack for password quality validation. This module produces warnings, rejecting or providing example passwords when changing your system password. It is used by default by OpenWall GNU/*/Linux and by FreeBSD. sys-auth/pambase:pwhistory - Enable pam_pwhistory module on system auth stack to save the last passwords for each user in order to force password change history and keep the user from alternating between the same password too frequently. sys-auth/pambase:pwquality - Enable pam_pwquality module on system auth stack for passwd quality validation. It is used by default by Fedora GNU/*/Linux. sys-auth/pambase:securetty - Enable pam_securetty module in the login stack. Not generally relevant anymore as the login stack only refers to local logins and local terminals imply secure access in the first place. sys-auth/pambase:sha512 - Switch Linux-PAM's pam_unix module to use sha512 for passwords hashes rather than MD5. This option requires sys-libs/pam version 1.0.1 built against sys-libs/glibc version 2.7, if it's built against an earlier version, it will silently be ignored, and MD5 hashes will be used. All the passwords changed after this USE flag is enabled will be saved to the shadow file hashed using SHA512 function. The password previously saved will be left untouched. Please note that while SHA512-hashed passwords will still be recognised if the USE flag is removed, the shadow file will not be compatible with systems using an earlier glibc version. sys-auth/pambase:sssd - Add System Security Services Daemon (sys-auth/sssd) support via pam_sss. sys-auth/pambase:systemd - Use pam_systemd module to register user sessions in the systemd control group hierarchy. sys-auth/pambase:yescrypt - Switch Linux-PAM's pam_unix module to use yescrypt for passwords hashes rather than MD5 sys-auth/polkit:daemon - Build polkitd in addition to libpolkit. sys-auth/polkit:duktape - Use dev-lang/duktape instead of dev-lang/spidermonkey as JavaScript engine sys-auth/polkit:systemd - Use sys-apps/systemd for session tracking sys-auth/seatd:builtin - Enable embedded server in libseat sys-auth/seatd:server - Enable standalone seatd server, replacement to (e)logind sys-auth/ssh-ldap-pubkey:schema - Install a copy of the LPK schema, only needed on LDAP servers. sys-auth/sssd:acl - Build and use the cifsidmap plugin sys-auth/sssd:keyutils - Controls whether the kernel keyring should be used via sys-apps/keyutils sys-auth/sssd:netlink - Add support for netlink protocol via dev-libs/libnl sys-auth/sssd:nfsv4 - Add support for the nfsv4 idmapd plugin provided by net-fs/nfs-utils sys-auth/sssd:samba - Add Privileged Attribute Certificate Support for Kerberos sys-auth/sssd:subid - Support subordinate uid and gid ranges in FreeIPA sys-auth/sssd:sudo - Build helper to let app-admin/sudo use sssd provided information sys-auth/sssd:systemtap - Enable SystemTAP/DTrace tracing sys-block/f3:extra - Build the additional f3probe, f3brew and f3fix utility (requires sys-block/parted and virtual/udev) sys-block/fio:aio - Enable AIO ioengine sys-block/fio:curl - Enable HTTP engine for S3 and WebDav support support via net-misc/curl sys-block/fio:glusterfs - Enable GlusterFS gfapi support via sys-cluster/glusterfs sys-block/fio:gnuplot - Install tools for generating gnuplots sys-block/fio:io-uring - Enable efficient I/O via sys-libs/liburing. sys-block/fio:nfs - Enable NFS support sys-block/fio:numa - Enable numa support sys-block/fio:pandas - Install dependencies for complex python scripts sys-block/fio:rbd - Enable Rados block device support via sys-cluster/ceph sys-block/fio:rdma - Enable infiniband support via sys-cluster/rdma-core sys-block/fio:tcmalloc - Link against dev-util/google-perftools by default which will speed up USE=rbd up to 20% sys-block/fio:zbc - Enable ZBC & ZAC disks via sys-block/libzbc. sys-block/gparted:wayland - Enable interim workaround to allow running GParted under Wayland by granting permission to the X11 display using x11-apps/xhost sys-block/libfabric:efa - Enable Amazon EC2 Elastic Fabric Adapter provider sys-block/libfabric:rocr - Enable Radeon Open Compute provider sys-block/libfabric:usnic - Enable Cisco VIC (virtualized NIC) hardware on Cisco UCS server provider sys-block/libfabric:verbs - Enable Linux Infiniband verbs provider sys-block/nbd:netlink - Add support for netlink protocol via dev-libs/libnl sys-block/nbdkit:ext2 - Enable the ext2 filter via sys-fs/e2fsprogs. sys-block/nbdkit:libguestfs - Enable the app-emulation/libguestfs plugin. sys-block/nbdkit:libssh - Enable the SSH plugin via net-libs/libssh. sys-block/nbdkit:libvirt - Enable the app-emulation/libvirt plugin. sys-block/nbdkit:nbd - Enable the nbd plugin via sys-libs/libnbd. sys-block/nbdkit:torrent - Enable the torrent plugin via net-libs/libtorrent-rasterbar. sys-block/nbdkit:zlib-ng - Use sys-libs/zlib-ng to handle zlib decompression. sys-block/ndctl:libtracefs - Use dev-libs/libtracefs to build cxl-monitor binary sys-block/open-iscsi:rdma - Support iSCSI over RDMA sys-block/open-iscsi:tcp - Support iSCSI over TCP sys-block/parted:debug - Enable debugging as encouraged by upstream: [The default configuration] includes --enable-debug (by default), which contains many assertions.

These symlinks are installed into slotted LLVM bindir, so they should not take precedence over symlinks installed into /usr/bin by sys-devel/gcc-config but they can be helpful for GCC-free setups. sys-devel/crosstool-ng:dtc - Require sys-apps/dtc sys-devel/crosstool-ng:lzip - Require app-arch/lzip sys-devel/crosstool-ng:meson - Require dev-build/meson sys-devel/crosstool-ng:ninja - Require app-alternatives/ninja sys-devel/crosstool-ng:rsync - Require net-misc/rsync sys-devel/crosstool-ng:wget - Require net-misc/wget sys-devel/distcc:gssapi - Enable support for net-libs/libgssglue sys-devel/gcc:ada - Build the ADA language (GNAT) frontend sys-devel/gcc:cet - Enable support for control flow hijacking protection. On amd64, this provides Intel Control Flow Enforcement Technology (CET). On arm64, this provides Branch Target Identification (BTI) and Pointer Authentication Code (PAC) support. This is only effective on amd64 or arm64. Only provides benefits on newer CPUs. For Intel, the CPU must be at least as new as Tiger Lake. For AMD, it must be at least as new as Zen 3. This is harmless on older CPUs, but provides no benefit either. For ARM64, PAC was introduced in armv8.3-a, and BTI was introduced in armv8.5-a. When combined with USE=hardened on amd64, GCC will set -fcf-protection by default when building software. The effect is minimal on systems which do not support it, other than a possible small increase in codesize for the NOPs. The generated code is therefore compatible with i686 at the earliest. On arm64, GCC will set -mbranch-protection=standard by default when building software. sys-devel/gcc:d - Enable support for the D programming language sys-devel/gcc:debug - Enables GCC's 'checking' facility via --enable-checking=yes,extra,rtl. This adds checks to various compiler passes for integrity and input validation. This can help catch possible miscompilations early as well as latent bugs which could become real problems in future, but at the cost of slower compile times when using GCC. Unrelated to backtraces. sys-devel/gcc:default-stack-clash-protection - Build packages with stack clash protection on by default as a hardening measure. This enables -fstack-clash-protection by default which protects against large memory allocations allowing stack smashing. May cause slightly increased codesize, but modern compilers have been adapted to optimize well for this case, as this mitigation is now quite common. See https://developers.redhat.com/blog/2020/05/22/stack-clash-mitigation-in-gcc-part-3 and https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt. sys-devel/gcc:default-znow - Request full relocation on start from ld.so by default. This sets the -z,now (BIND_NOW) flag by default on all linker invocations. By resolving all dynamic symbols at application startup, parts of the program can be made read-only as a hardening measure. This is closely related to RELRO which is also separately enabled by default. In some applications with many unresolved symbols (heavily plugin based, for example), startup time may be impacted. sys-devel/gcc:fixed-point - Enable fixed-point arithmetic support for MIPS targets in gcc (Warning: significantly increases compile time!) sys-devel/gcc:go - Build the GCC Go language frontend. sys-devel/gcc:graphite - Add support for the framework for loop optimizations based on a polyhedral intermediate representation sys-devel/gcc:ieee-long-double - Use accelerated 128-bit IEEE long double ABI (ppc64le only) sys-devel/gcc:jit - Enable libgccjit so other applications can embed gcc for Just-In-Time compilation. sys-devel/gcc:libssp - Build SSP support into a dedicated library rather than use the code in the C library (DO NOT ENABLE THIS IF YOU DON'T KNOW WHAT IT DOES) sys-devel/gcc:lto - Build using Link Time Optimizations (LTO). Note that GCC is always built with support for building other programs with LTO. This USE flag is for whether GCC itself is built and optimized with LTO. sys-devel/gcc:modula2 - Build the GCC Modula-2 language frontend. sys-devel/gcc:objc - Build support for the Objective C code language sys-devel/gcc:objc++ - Build support for the Objective C++ language sys-devel/gcc:objc-gc - Build support for the Objective C code language Garbage Collector sys-devel/gcc:pgo - Build GCC using Profile Guided Optimization (PGO). GCC will build itself and then analyze the just-built binary and then rebuild itself using the data obtained from analysis of codepaths taken. It does not affect whether GCC itself supports PGO when building other software. This substantially increases the build time needed for building GCC itself. sys-devel/gcc:rust - Build support for the Rust language, installs gccrs. sys-devel/gcc:sanitize - Build support for various sanitizer functions (ASAN/TSAN/etc...) to find runtime problems in applications. sys-devel/gcc:ssp - Build packages with stack smashing protection on by default sys-devel/gcc:systemtap - enable systemtap static probe points sys-devel/gcc:vtv - Build support for virtual table verification (a C++ hardening feature). This does not control whether GCC defaults to using VTV> Note that actually using VTV breaks ABI and hence the whole system must be built with -fvtable-verify. sys-devel/gcc-apple:bootstrap - !DO NOT SET THIS FLAG YOURSELF! avoids need for autoconf during bootstrap stage2 sys-devel/gcc-apple:objc - Build support for the Objective C code language sys-devel/gcc-apple:objc++ - Build support for the Objective C++ language sys-devel/gcc-config:cc-wrappers - Install and manage 'cc' and 'f77' wrappers in /usr/bin. Otherwise ignore them. sys-devel/gcc-config:native-symlinks - Install native symlinks like 'gcc' or 'g++' to /usr/bin. Otherwise keep only ${CTARGET}-gcc and friends. sys-devel/gettext:git - When running `autopoint`, use git to store the internal development files; this requires git at runtime, but will be faster/smaller than raw archives sys-devel/lld-toolchain-symlinks:multilib-symlinks - Install symlinks for all ABI CHOSTs. Note that this can result in gcc being overrode for native builds, as well as conflict with crossdev if used for the same targets. sys-devel/lld-toolchain-symlinks:native-symlinks - Install generic 'ld' symlink, as well as ${CTARGET}-ld. These symlinks are installed into slotted LLVM bindir, so they should not take precedence over symlinks installed into /usr/bin by sys-devel/binutils-config but they can be helpful for binutils-free setups. sys-devel/llvm:binutils-plugin - Build the binutils plugin sys-devel/llvm:debuginfod - Install llvm-debuginfod (requires net-misc/curl and dev-cpp/cpp-httplib) sys-devel/llvm:doc - Build and install the HTML documentation and regenerate the man pages sys-devel/llvm:exegesis - Enable performance counter support for llvm-exegesis tool that can be used to measure host machine instruction characteristics sys-devel/llvm:ncurses - Support querying terminal properties using ncurses' terminfo sys-devel/llvm:xar - Support dumping LLVM bitcode sections in Mach-O files (uses app-arch/xar) sys-devel/llvm:z3 - Enable support for sci-mathematics/z3 constraint solver sys-devel/llvm-toolchain-symlinks:multilib-symlinks - Install symlinks for all ABI CHOSTs. Note that this can result in gcc being overrode for native builds, as well as conflict with crossdev if used for the same targets. sys-devel/llvm-toolchain-symlinks:native-symlinks - Install generic tool symlinks like 'objdump' and 'ranlib', as well as ${CTARGET}-*. These symlinks are installed into slotted LLVM bindir, so they should not take precedence over symlinks installed into /usr/bin by sys-devel/binutils-config but they can be helpful for binutils-free setups. sys-devel/sparse:gtk -
