# Using RPM build flags
|
||||||
|
|
||||||
|
The %set_build_flags macro sets the environment variables `CFLAGS`,
|
||||||
|
`CXXFLAGS`, `FFLAGS`, `FCFLAGS`, `VALAFLAGS`, `LDFLAGS` and `LT_SYS_LIBRARY_PATH` to
|
||||||
|
the value of their corresponding rpm macros. `%set_build_flags` is automatically
|
||||||
|
called prior to the `%build`, `%check`, and `%install` phases so these flags can be
|
||||||
|
used by makefiles and other build tools.
|
||||||
|
|
||||||
|
You can opt out of this behavior by doing:
|
||||||
|
|
||||||
|
%undefine _auto_set_build_flags
|
||||||
|
|
||||||
|
If you do opt out of this behavior, you can still manually use `%set_build_flags`
|
||||||
|
by adding it to the `%build` section of your spec file or by using one of the
|
||||||
|
build system helper macros like `%configure`, `%cmake`, and `%meson`.
|
||||||
|
|
||||||
|
For packages which use autoconf to set up the build environment, use
|
||||||
|
the `%configure` macro to obtain the full complement of flags, like
|
||||||
|
this:
|
||||||
|
|
||||||
|
%configure
|
||||||
|
|
||||||
|
This will invoke `./configure` with arguments (such as
|
||||||
|
`--prefix=/usr`) to adjust the paths to the packaging defaults. Prior
|
||||||
|
to that, some common problems in autotools scripts are automatically
|
||||||
|
patched across the source tree.
|
||||||
|
|
||||||
|
Individual build flags are also available through RPM macros:
|
||||||
|
|
||||||
|
* `%{build_cc}` for the command name of the C compiler.
|
||||||
|
* `%{build_cxx}` for the command name of the C++ compiler.
|
||||||
|
* `%{build_cpp}` for the command name of the C-compatible preprocessor.
|
||||||
|
* `%{build_cflags}` for the C compiler flags (also known as the
|
||||||
|
`CFLAGS` variable).
|
||||||
|
* `%{build_cxxflags}` for the C++ compiler flags (usually assigned to
|
||||||
|
the `CXXFLAGS` shell variable).
|
||||||
|
* `%{build_fflags}` for `FFLAGS` (the Fortran compiler flags, also
|
||||||
|
known as the `FCFLAGS` variable).
|
||||||
|
* `%{build_valaflags}` for `VALAFLAGS` (the Vala compiler flags)
|
||||||
|
* `%{build_ldflags}` for the linker (`ld`) flags, usually known as
|
||||||
|
`LDFLAGS`. Note that the contents quote linker arguments using
|
||||||
|
`-Wl`, so this variable is intended for use with the `gcc` compiler
|
||||||
|
driver. At the start of the `%build` section, the environment
|
||||||
|
variable `RPM_LD_FLAGS` is set to this value.
|
||||||
|
|
||||||
|
The C and C++ compiler flags are historically available as the
|
||||||
|
`%{optflags}` macro. These flags may not contain flags that work with
|
||||||
|
certain languagues or compiler front ends, so the language-specific
|
||||||
|
`%build_*` are more precise. At the start of the `%build` section,
|
||||||
|
the environment variable `RPM_OPT_FLAGS` is set to the `%{optflags}`
|
||||||
|
value; similar limitations apply.
|
||||||
|
|
||||||
|
The variable `LT_SYS_LIBRARY_PATH` is defined here to prevent the `libtool`
|
||||||
|
script (v2.4.6+) from hardcoding `%_libdir` into the binaries' `RPATH`.
|
||||||
|
|
||||||
|
These RPM macros do not alter shell environment variables.
|
||||||
|
|
||||||
|
For some other build tools separate mechanisms exist:
|
||||||
|
|
||||||
|
* CMake builds use the the `%cmake` macro from the `cmake-rpm-macros`
|
||||||
|
package.
|
||||||
|
|
||||||
|
Care must be taking not to compile the current selection of compiler
|
||||||
|
flags into any RPM package besides `redhat-rpm-config`, so that flag
|
||||||
|
changes are picked up automatically once `redhat-rpm-config` is
|
||||||
|
updated.
|
||||||
|
|
||||||
|
# Flag selection for the build type
|
||||||
|
|
||||||
|
The default flags are suitable for building applications.
|
||||||
|
|
||||||
|
For building shared objects, you must compile with `-fPIC` in
|
||||||
|
(`CFLAGS` or `CXXFLAGS`) and link with `-shared` (in `LDFLAGS`).
|
||||||
|
|
||||||
|
For other considerations involving shared objects, see:
|
||||||
|
|
||||||

* [Fedora Packaging Guidelines: Shared Libraries](https://docs.fedoraproject.org/en-US/packaging-guidelines/#_shared_libraries)
|
||||||
|

||||||

# Customizing compiler and other build flags
|
||||||
|
|
||||||
|
It is possible to set RPM macros to change some aspects of the
|
||||||
|
compiler flags. Changing these flags should be used as a last
|
||||||
|
recourse if other workarounds are not available.
|
||||||
|
|
||||||
|
### Toolchain selection
|
||||||
|
|
||||||
|
The default toolchain uses GCC, and the `%toolchain` macro is defined
|
||||||
|
as `gcc`.
|
||||||
|
|
||||||
|
It is enough to override `toolchain` macro and all relevant macro for C/C++
|
||||||
|
compilers will be switched. Either in the spec or in the command-line.
|
||||||
|
|
||||||
|
%global toolchain clang
|
||||||
|
|
||||||
|
or:
|
||||||
|
|
||||||
|
rpmbuild -D "toolchain clang" …
|
||||||
|
|
||||||
|
Inside a spec file it is also possible to determine which toolchain is in use
|
||||||
|
by testing the same macro. For example:
|
||||||
|
|
||||||
|
%if "%{toolchain}" == "gcc"
|
||||||
|
BuildRequires: gcc
|
||||||
|
%endif
|
||||||
|
|
||||||
|
or:
|
||||||
|
|
||||||
|
%if "%{toolchain}" == "clang"
|
||||||
|
BuildRequires: clang compiler-rt
|
||||||
|
%endif
|
||||||
|
|
||||||
|
### Controlling Type Safety
|
||||||
|
|
||||||
|
The macro `%build_type_safety_c` can be set to change the C type
|
||||||
|
safety level. The default level is 3, see below. It can be set to 0
|
||||||
|
to get historic levels of type safety. Changing the type safety level
|
||||||
|
may depend on correct `CFLAGS` propagation during the build. The
|
||||||
|
`%build_type_safety_c` macro needs to be set before `CFLAGS`-related
|
||||||
|
macros are expanded by RPM (that is, earlier in the file works
|
||||||
|
better).
|
||||||
|
|
||||||
|
Packages can set `%build_type_safety_c` to higher values to adopt
|
||||||
|
future distribution-wide type-safety increases early. When changing
|
||||||
|
the `%build_type_safety_c` level to increase it, spec file should use
|
||||||
|
a construct like this to avoid *lowering* a future default:
|
||||||
|
|
||||||
|
```
|
||||||
|
%if %build_type_safety_c < 4
|
||||||
|
%global build_type_safety_c 4
|
||||||
|
%endif
|
||||||
|
```
|
||||||
|
|
||||||
|
At level 0, all C constructs that GCC accepts for backwards
|
||||||
|
compatibility with obsolete language standards are accepted during
|
||||||
|
package builds. This is achieved by passing `-fpermissive` to GCC.
|
||||||
|
|
||||||
|
At level 1, the following additional error categories are enabled:
|
||||||
|
|
||||||
|
* `-Werror=implicit-int`: Reject declarations and definitions that
|
||||||
|
omit a type name where one is required. Examples are:
|
||||||
|
`extern int_variable;`, `extern int_returning_function (void);`,
|
||||||
|
and missing separate parameter type declarations in old-style
|
||||||
|
function definitions.
|
||||||
|
* `-Werror=implicit-function-declaration`: Reject calls to functions
|
||||||
|
to undeclared functions such as `function_not_defined_anywhere ()`.
|
||||||
|
Previously, such expressions where we compiled as if a declaration
|
||||||
|
`extern int function_not_defined_anywhere ();` (a prototype-less
|
||||||
|
function declaration) were in scope.
|
||||||
|
* `-Werror=return-mismatch`: Reject `return` statements with missing
|
||||||
|
or extra expressions, based on the declared return type of the
|
||||||
|
function.
|
||||||
|
* `-Wdeclaration-missing-parameter-type`: Reject function declarations
|
||||||
|
that contain unknown type names (which used to be treated as ignored
|
||||||
|
identifier names).
|
||||||
|
|
||||||
|
At level 2, the following error category is enabled in addition:
|
||||||
|
|
||||||
|
* `-Werror=int-conversion`: Reject the use of integer expressions
|
||||||
|
where a pointer type expected, and pointer expressions where an
|
||||||
|
integer type is expected. Without this option, GCC may produce an
|
||||||
|
executable, but often, there are failures at run time because not
|
||||||
|
the full 64 bits of pointers are preserved.
|
||||||
|
|
||||||
|
The additional level 3 error category is:
|
||||||
|
|
||||||
|
* `-Werror=incompatible-pointer-types`: An expression of one pointer
|
||||||
|
type is used where different pointer type is expected. (This does
|
||||||
|
not cover signed/unsigned mismatches in the pointer target type.)
|
||||||
|
|
||||||
|
Clang errors out on more obsolete and invalid C constructs than C, so
|
||||||
|
the type safety is higher by default than with the GCC toolchain.
|
||||||
|
|
||||||
|
### Disable autotools compatibility patching
|
||||||
|
|
||||||
|
By default, the invocation of the `%configure` macro replaces
|
||||||
|
`config.guess` files in the source tree with the system version. To
|
||||||
|
disable that, define this macro:
|
||||||
|
|
||||||
|
%global _configure_gnuconfig_hack 0
|
||||||
|
|
||||||
|
`%configure` also patches `ltmain.sh` scripts, so that linker flags
|
||||||
|
are set as well during libtool-. This can be switched off using:
|
||||||
|
|
||||||
|
%global _configure_libtool_hardening_hack 0
|
||||||
|
|
||||||
|
Further patching happens in LTO mode, see below.
|
||||||
|
|
||||||
|
### Other autotools compatibility settings
|
||||||
|
|
||||||
|
During `%configure`, `--runstatedir` is automatically passed to the
|
||||||
|
`configure` script if support for this option is detected. This
|
||||||
|
detection can fail if the package has multiple `configure` scripts
|
||||||
|
that invoke each other, and only some of them support `--runstatedir`.
|
||||||
|
To disable passing `--runstatedir`, use:
|
||||||
|
|
||||||
|
%undefine _configure_use_runstatedir
|
||||||
|
|
||||||
|
### Disabling Link-Time Optimization
|
||||||
|
|
||||||
|
By default, builds use link-time optimization. In this build mode,
|
||||||
|
object code is generated at the time of the final link, by combining
|
||||||
|
information from all available translation units, and taking into
|
||||||
|
account which symbols are exported.
|
||||||
|
|
||||||
|
To disable this optimization, include this in the spec file:
|
||||||
|
|
||||||
|
%global _lto_cflags %{nil}
|
||||||
|
|
||||||
|
If LTO is enabled, `%configure` applies some common required fixes to
|
||||||
|
`configure` scripts. To disable that, define the RPM macro
|
||||||
|
`_fix_broken_configure_for_lto` as `true` (sic; it has to be a shell
|
||||||
|
command).
|
||||||
|
|
||||||
|
### Lazy binding
|
||||||
|
|
||||||
|
If your package depends on the semantics of lazy binding (e.g., it has
|
||||||
|
plugins which load additional plugins to complete their dependencies,
|
||||||
|
before which some referenced functions are undefined), you should put
|
||||||
|
`-Wl,-z,lazy` at the end of the `LDFLAGS` setting when linking objects
|
||||||
|
which have such requirements. Under these circumstances, it is
|
||||||
|
unnecessary to disable hardened builds (and thus lose full ASLR for
|
||||||
|
executables), or link everything without `-Wl,z,now` (non-lazy
|
||||||
|
binding).
|
||||||
|
|
||||||
|
### Hardened builds
|
||||||
|
|
||||||
|
By default, the build flags enable fully hardened builds. To change
|
||||||
|
this, include this in the RPM spec file:
|
||||||
|
|
||||||
|
%undefine _hardened_build
|
||||||
|
|
||||||
|
This turns off certain hardening features, as described in detail
|
||||||
|
below. The main difference is that executables will be
|
||||||
|
position-dependent (no full ASLR) and use lazy binding.
|
||||||
|
|
||||||
|
### Source Fortification
|
||||||
|
|
||||||
|
By default, the build flags include `-Wp,-D_FORTIFY_SOURCE=3`: Source
|
||||||
|
fortification activates various hardening features in glibc:
|
||||||
|
|
||||||
|
* String functions such as `memcpy` attempt to detect buffer lengths
|
||||||
|
and terminate the process if a buffer overflow is detected.
|
||||||
|
* `printf` format strings may only contain the `%n` format specifier
|
||||||
|
if the format string resides in read-only memory.
|
||||||
|
* `open` and `openat` flags are checked for consistency with the
|
||||||
|
presence of a *mode* argument.
|
||||||
|
* Plus other minor hardening changes.
|
||||||
|
|
||||||
|
These changes can, on rare occasions, break valid programs. The source
|
||||||
|
fortification level can be overridden by adding this in the RPM spec file:
|
||||||
|
|
||||||
|
%define _fortify_level 2
|
||||||
|
|
||||||
|
to reduce source fortification level to 2 or:
|
||||||
|
|
||||||
|
%undefine _fortify_level
|
||||||
|
|
||||||
|
to disable fortification altogether.
|
||||||
|
|
||||||
|
### Annotated builds/watermarking
|
||||||
|
|
||||||
|
By default, the build flags cause a special output section to be
|
||||||
|
included in ELF files which describes certain aspects of the build.
|
||||||
|
To change this for all compiler invocations, include this in the RPM
|
||||||
|
spec file:
|
||||||
|
|
||||||
|
%undefine _annotated_build
|
||||||
|
|
||||||
|
Be warned that this turns off watermarking, making it impossible to do
|
||||||
|
full hardening coverage analysis for any binaries produced.
|
||||||
|
|
||||||
|
It is possible to disable annotations for individual compiler
|
||||||
|
invocations, using the `-fplugin-arg-annobin-disable` flag. However,
|
||||||
|
the annobin plugin must still be loaded for this flag to be
|
||||||
|
recognized, so it has to come after the hardening flags on the command
|
||||||
|
line (it has to be added at the end of `CFLAGS`, or specified after
|
||||||
|
the `CFLAGS` variable contents).
|
||||||
|
|
||||||
|
### Keeping dependencies on unused shared objects
|
||||||
|
|
||||||
|
By default, ELF shared objects which are listed on the linker command
|
||||||
|
line, but which have no referencing symbols in the preceding objects,
|
||||||
|
are not added to the output file during the final link.
|
||||||
|
|
||||||
|
In order to keep dependencies on shared objects even if none of
|
||||||
|
their symbols are used, include this in the RPM spec file:
|
||||||
|
|
||||||
|
%undefine _ld_as_needed
|
||||||
|
|
||||||
|
For example, this can be required if shared objects are used for their
|
||||||
|
side effects in ELF constructors, or for making them available to
|
||||||
|
dynamically loaded plugins.
|
||||||
|
|
||||||
|
### Switching to legacy relative relocations
|
||||||
|
|
||||||
|
By default, ELF objects use the architecture-independent `DT_RELR`
|
||||||
|
mechanism for relative relocations. To switch to the older,
|
||||||
|
architecture-specific relocation scheme, add this to the RPM spec file:
|
||||||
|
|
||||||
|
%undefine _ld_pack_relocs
|
||||||
|
|
||||||
|
This adds `-Wl,-z,pack-relative-relocs` to the linker flags (`LDFLAGS`).
|
||||||
|
|
||||||
|
### Specifying the build-id algorithm
|
||||||
|
|
||||||
|
If you want to specify a different build-id algorithm for your builds, you
|
||||||
|
can use the `%_build_id_flags` macro:
|
||||||
|
|
||||||
|
%_build_id_flags -Wl,--build-id=sha1
|
||||||
|
|
||||||
|
### Strict symbol checks in the link editor (ld)
|
||||||
|
|
||||||
|
Optionally, the link editor will refuse to link shared objects which
|
||||||
|
contain undefined symbols. Such symbols lack symbol versioning
|
||||||
|
information and can be bound to the wrong (compatibility) symbol
|
||||||
|
version at run time, and not the actual (default) symbol version which
|
||||||
|
would have been used if the symbol definition had been available at
|
||||||
|
static link time. Furthermore, at run time, the dynamic linker will
|
||||||
|
not have complete dependency information (in the form of DT_NEEDED
|
||||||
|
entries), which can lead to errors (crashes) if IFUNC resolvers are
|
||||||
|
executed before the shared object containing them is fully relocated.
|
||||||
|
|
||||||
|
To switch on these checks, define this macro in the RPM spec file:
|
||||||
|
|
||||||
|
%global _strict_symbol_defs_build 1
|
||||||
|
|
||||||
|
If this RPM spec option is active, link failures will occur if the
|
||||||
|
linker command line does not list all shared objects which are needed.
|
||||||
|
In this case, you need to add the missing DSOs (with linker arguments
|
||||||
|
such as `-lm`). As a result, the link editor will also generated the
|
||||||
|
necessary DT_NEEDED entries.
|
||||||
|
|
||||||
|
In some cases (such as when a DSO is loaded as a plugin and is
|
||||||
|
expected to bind to symbols in the main executable), undefined symbols
|
||||||
|
are expected. In this case, you can add
|
||||||
|
|
||||||
|
%undefine _strict_symbol_defs_build
|
||||||
|
|
||||||
|
to the RPM spec file to disable these strict checks. Alternatively,
|
||||||
|
you can pass `-z undefs` to ld (written as `-Wl,-z,undefs` on the gcc
|
||||||
|
command line). The latter needs binutils 2.29.1-12.fc28 or later.
|
||||||
|
|
||||||
|
### Legacy -fcommon
|
||||||
|
|
||||||
|
Since version 10, [gcc defaults to `-fno-common`](https://gcc.gnu.org/gcc-10/porting_to.html#common).
|
||||||
|
Builds may fail with `multiple definition of ...` errors.
|
||||||
|
|
||||||
|
As a short term workaround for such failure,
|
||||||
|
it is possible to add `-fcommon` to the flags by defining `%_legacy_common_support`.
|
||||||
|
|
||||||
|
%global _legacy_common_support 1
|
||||||
|
|
||||||
|
Properly fixing the failure is always preferred!
|
||||||
|
|
||||||
|
### Package note on ELF objects
|
||||||
|
|
||||||
|
A note that describes the package name, version, and architecture is
|
||||||
|
inserted via a linker script (`%_package_note_file`). The script is
|
||||||
|
generated when `%set_build_flags` is called. The linker option that
|
||||||
|
injects the linker script is added to `%{build_ldflags}` via the
|
||||||
|
`%{_package_note_flags}` macro.
|
||||||
|
|
||||||
|
To opt out of the use of this feature completely, the best way is to
|
||||||
|
undefine the first macro. Include this in the spec file:
|
||||||
|
|
||||||
|
%undefine _package_note_file
|
||||||
|
|
||||||
|
The other macros can be undefined too to replace parts of the functionality.
|
||||||
|
If `%_generate_package_note_file` is undefined, the linker script will not
|
||||||
|
be generated, but the link flags may still refer to it. This may be useful
|
||||||
|
if the default generation method is insufficient and a different mechanism
|
||||||
|
will be used to generate `%_package_note_file`. If `%_package_note_flags`
|
||||||
|
is undefined, the linker argument that injects the script will not be added
|
||||||
|
to `%build_ldfags`, but the linker script would still be generated.
|
||||||
|
|
||||||
|
### Frame pointers
|
||||||
|
|
||||||
|
Frame pointers will be included by default via the `%_include_frame_pointers`
|
||||||
|
macro. To opt out, the best way is to undefine the macro. Include this in the
|
||||||
|
spec file:
|
||||||
|
|
||||||
|
%undefine _include_frame_pointers
|
||||||
|
|
||||||
|
Note that opting out might still result in frame pointers being included on
|
||||||
|
architectures where they are part of the ABI (e.g. aarch64) depending on
|
||||||
|
compiler defaults.
|
||||||
|
|
||||||
|
### Post-build ELF object processing
|
||||||
|
|
||||||
|
By default, DWARF debugging information is separated from installed
|
||||||
|
ELF objects and put into `-debuginfo` subpackages. To disable most
|
||||||
|
debuginfo processing (and thus the generation of these subpackages),
|
||||||
|
define `_enable_debug_packages` as `0`.
|
||||||
|
|
||||||
|
Processing of debugging information is controlled using the
|
||||||
|
`find-debuginfo` tool from the `debugedit` package. Several aspects
|
||||||
|
of its operation can be controlled at the RPM level.
|
||||||
|
|
||||||
|
* Creation of `-debuginfo` subpackages is enabled by default.
|
||||||
|
To disable, undefine `_debuginfo_subpackages`.
|
||||||
|
* Likewise, `-debugsource` subpackages are automatically created.
|
||||||
|
To disable, undefine `_debugsource_subpackages`.
|
||||||
|
See [Separate Subpackage and Source Debuginfo](https://fedoraproject.org/wiki/Changes/SubpackageAndSourceDebuginfo)
|
||||||
|
for background information.
|
||||||
|
* `_build_id_links`, `_unique_build_ids`, `_unique_debug_names`,
|
||||||
|
`_unique_debug_srcs` control how debugging information and
|
||||||
|
corresponding source files are represented on disk.
|
||||||
|
See `/usr/lib/rpm/macros` for details. The defaults
|
||||||
|
enable parallel installation of `-debuginfo` packages for
|
||||||
|
different package versions, as described in
|
||||||
|
[Parallel Installable Debuginfo](https://fedoraproject.org/wiki/Changes/ParallelInstallableDebuginfo).
|
||||||
|
* By default, a compressed symbol table is preserved in the
|
||||||
|
`.gnu_debugdata` section. To disable that, undefine
|
||||||
|
`_include_minidebuginfo`.
|
||||||
|
* To speed up debuggers, a `.gdb_index` section is created. It can be
|
||||||
|
disabled by undefining `_include_gdb_index`.
|
||||||
|
* Missing build IDs result in a build failure. To ignore such
|
||||||
|
problems, undefine `_missing_build_ids_terminate_build`.
|
||||||
|
* During processing, build IDs are recomputed to match the binary
|
||||||
|
content. To skip this step, define `_no_recompute_build_ids` as `1`.
|
||||||
|
* By default, the options in `_find_debuginfo_dwz_opts` turn on `dwz`
|
||||||
|
(DWARF compression) processing. Undefine this macro to disable this
|
||||||
|
step.
|
||||||
|
* Additional options can be passed by defining the
|
||||||
|
`_find_debuginfo_opts` macro.
|
||||||
|
|
||||||
|
After separation of debugging information, additional transformations
|
||||||
|
are applied, most of them also related to debugging information.
|
||||||
|
These steps can be skipped by undefining the corresponding macros:
|
||||||
|
|
||||||
|
* `__brp_strip`: Removal of leftover debugging information. The tool
|
||||||
|
specified by the `__strip` macro is invoked with the `-g` option on
|
||||||
|
ELF object (`.o`) files.
|
||||||
|
* `__brp_strip_static_archive`: This is similar to `__brp_strip`, but
|
||||||
|
processes static `.a` archives instead.
|
||||||
|
* `__brp_strip_comment_note`: This step removes unallocated `.note`
|
||||||
|
sections, and `.comment` sections from ELF files.
|
||||||
|
* `__brp_strip_lto`: This step removes GCC LTO intermediate representation
|
||||||
|
in ELF sections starting with `.gnu.lto_` and `.gnu.debuglto_`. Skipping
|
||||||
|
this step is strongly discouraged because the tight coupling of LTO
|
||||||
|
data with the GCC version. The underlying tool is again determined by the
|
||||||
|
`__strip` macro.
|
||||||
|
* `__brp_llvm_compile_lto_elf`: This step replaces LLVM bitcode files
|
||||||
|
with object files, thereby removing LLVM bitcode from the installed
|
||||||
|
files. This transformation is applied to object files in static `.a`
|
||||||
|
archives, too.
|
||||||
|
* `__brp_ldconfig`: For each shared object on the library search path
|
||||||
|
whose soname does not match its file name, a symbolic link from the
|
||||||
|
soname to the file name is created. This way, these shared objects
|
||||||
|
are loadable immediately after installation, even if they are not yet
|
||||||
|
listed in the `/etc/ld.so.cache` file (because `ldconfig` has not been
|
||||||
|
invoked yet).
|
||||||
|
* `__brp_remove_la_files`: This step removes libtool-generated `.la`
|
||||||
|
files from the installed files.
|
||||||
|
|
||||||
|
# Individual compiler flags
|
||||||
|
|
||||||
|
Compiler flags end up in the environment variables `CFLAGS`,
|
||||||
|
`CXXFLAGS`, `FFLAGS`, and `FCFLAGS`.
|
||||||
|
|
||||||
|
The general (architecture-independent) build flags are:
|
||||||
|
|
||||||
|
* `-O2`: Turn on various GCC optimizations. See the
|
||||||
|
[GCC manual](https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-O2).
|
||||||
|
Optimization improves performance, the accuracy of warnings, and the
|
||||||
|
reach of toolchain-based hardening, but it makes debugging harder.
|
||||||
|
* `-g`: Generate debugging information (DWARF). In Fedora, this data
|
||||||
|
is separated into `-debuginfo` RPM packages whose installation is
|
||||||
|
optional, so debuging information does not increase the size of
|
||||||
|
installed binaries by default.
|
||||||
|
* `-pipe`: Run compiler and assembler in parallel and do not use a
|
||||||
|
temporary file for the assembler input. This can improve
|
||||||
|
compilation performance. (This does not affect code generation.)
|
||||||
|
* `-Wall`: Turn on various GCC warnings.
|
||||||
|
See the [GCC manual](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wall).
|
||||||
|
* `-Wno-complain-wrong-lang`: Do not warn about front end mismatches
|
||||||
|
(e.g, using `-Werror=format-security` with Fortran). Only included
|
||||||
|
in `%optflags`, and not the front-end-specific `%build_*` macros.
|
||||||
|
* `-Werror=format-security`: Turn on format string warnings and treat
|
||||||
|
them as errors.
|
||||||
|
See the [GCC manual](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wformat-security).
|
||||||
|
This can occasionally result in compilation errors. In that case,
|
||||||
|
the best option is to rewrite the source code so that only constant
|
||||||
|
format strings (string literals) are used.
|
||||||
|
* Other `-Werror=` options. See **Controlling C Type Safety**.
|
||||||
|
* `-U_FORTIFY_SOURCE, -Wp,-U_FORTIFY_SOURCE -Wp,-D_FORTIFY_SOURCE=3`:
|
||||||
|
See the Source Fortification section above and the `%_fortify_level`
|
||||||
|
override.
|
||||||
|
* `-fexceptions`: Provide exception unwinding support for C programs.
|
||||||
|
See the [`-fexceptions` option in the GCC
|
||||||
|
manual](https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#index-fexceptions)
|
||||||
|
and the [`cleanup` variable
|
||||||
|
attribute](https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#index-cleanup-variable-attribute).
|
||||||
|
This also hardens cancellation handling in C programs because
|
||||||
|
it is not required to use an on-stack jump buffer to install
|
||||||
|
a cancellation handler with `pthread_cleanup_push`. It also makes
|
||||||
|
it possible to unwind the stack (using C++ `throw` or Rust panics)
|
||||||
|
from C callback functions if a C library supports non-local exits
|
||||||
|
from them (e.g., via `longjmp`).
|
||||||
|
* `-fasynchronous-unwind-tables`: Generate full unwind information
|
||||||
|
covering all program points. This is required for support of
|
||||||
|
asynchronous cancellation and proper unwinding from signal
|
||||||
|
handlers. It also makes performance and debugging tools more
|
||||||
|
useful because unwind information is available without having to
|
||||||
|
install (and load) debugging information. (Not enabled on armhfp
|
||||||
|
due to architectural differences in stack management.)
|
||||||
|
* `-Wp,-D_GLIBCXX_ASSERTIONS`: Enable lightweight assertions in the
|
||||||
|
C++ standard library, such as bounds checking for the subscription
|
||||||
|
operator on vectors. (This flag is added to both `CFLAGS` and
|
||||||
|
`CXXFLAGS`; C compilations will simply ignore it.)
|
||||||
|
* `-fstack-protector-strong`: Instrument functions to detect
|
||||||
|
stack-based buffer overflows before jumping to the return address on
|
||||||
|
the stack. The *strong* variant only performs the instrumentation
|
||||||
|
for functions whose stack frame contains addressable local
|
||||||
|
variables. (If the address of a variable is never taken, it is not
|
||||||
|
possible that a buffer overflow is caused by incorrect pointer
|
||||||
|
arithmetic involving a pointer to that variable.)
|
||||||
|
* `-fstack-clash-protection`: Turn on instrumentation to avoid
|
||||||
|
skipping the guard page in large stack frames. (Without this flag,
|
||||||
|
vulnerabilities can result where the stack overlaps with the heap,
|
||||||
|
or thread stacks spill into other regions of memory.) This flag is
|
||||||
|
fully ABI-compatible and has adds very little run-time overhead.
|
||||||
|
This flag is currently not available on armhfp (both `gcc` and `clang`
|
||||||
|
toolchains) and on aarch64 with the `clang` toolchain.
|
||||||
|
* `-flto=auto`: Enable link-time optimization (LTO), using `make` job server
|
||||||
|
integration for parallel processing. (`gcc` toolchain only)
|
||||||
|
* `-ffat-lto-objects`: Generate EFL object files which contain both
|
||||||
|
object code and LTO intermediate representation. (`gcc` toolchain only)
|
||||||
|
* `-flto`: Enable link-time optimization. (`clang` toolchain only)
|
||||||
|
* `-grecord-gcc-switches`: Include select GCC command line switches in
|
||||||
|
the DWARF debugging information. This is useful for detecting the
|
||||||
|
presence of certain build flags and general hardening coverage.
|
||||||
|
* `-fcommon`: This optional flag is used to build legacy software
|
||||||
|
which relies on C tentative definitions. It is disabled by default.
|
||||||
|
|
||||||
|
For hardened builds (which are enabled by default, see above for how
|
||||||
|
to disable them), the flag
|
||||||
|
`-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1` is added to the
|
||||||
|
command line. It adds the following flag to the command line:
|
||||||
|
|
||||||
|
* `-fPIE`: Compile for a position-independent executable (PIE),
|
||||||
|
enabling full address space layout randomization (ASLR). This is
|
||||||
|
similar to `-fPIC`, but avoids run-time indirections on certain
|
||||||
|
architectures, resulting in improved performance and slightly
|
||||||
|
smaller executables. However, compared to position-dependent code
|
||||||
|
(the default generated by GCC), there is still a measurable
|
||||||
|
performance impact.
|
||||||
|
|
||||||
|
If the command line also contains `-r` (producing a relocatable
|
||||||
|
object file), `-fpic` or `-fPIC`, this flag is automatically
|
||||||
|
dropped. (`-fPIE` can only be used for code which is linked into
|
||||||
|
the main program.) Code which goes into static libraries should be
|
||||||
|
compiled with `-fPIE`, except when this code is expected to be
|
||||||
|
linked into DSOs, when `-fPIC` must be used.
|
||||||
|
|
||||||
|
To be effective, `-fPIE` must be used with the `-pie` linker flag
|
||||||
|
when producing an executable, see below.
|
||||||
|
|
||||||
|
To support [binary watermarks for ELF
|
||||||
|
objects](https://fedoraproject.org/wiki/Toolchain/Watermark) using
|
||||||
|
annobin, the `-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1` flag is
|
||||||
|
added by default (with the `gcc` toolchain). This can be switched off
|
||||||
|
by undefining the `%_annotated_build` RPM macro (see above). Binary
|
||||||
|
watermarks are currently disabled on armhpf, and with the `clang`
|
||||||
|
toolchain.
|
||||||
|
|
||||||
|
If frame pointers are enabled by default (via `%_include_frame_pointers`),
|
||||||
|
the `-fno-omit-frame-pointer` will be added on all architectures except i686
|
||||||
|
and s390x. Additional flags will be added on specific architectures:
|
||||||
|
|
||||||
|
* `-mno-omit-leaf-frame-pointer` on x86_64 and aarch64
|
||||||
|
|
||||||
|
### Architecture-specific compiler flags
|
||||||
|
|
||||||
|
These compiler flags are enabled for all builds (hardened/annotated or
|
||||||
|
not), but their selection depends on the architecture:
|
||||||
|
|
||||||
|
* `-fcf-protection`: Instrument binaries to guard against
|
||||||
|
ROP/JOP exploitation techniques. Used on x86_64.
|
||||||
|
* `-mbranch-protection=standard`: Instrument binaries to guard against
|
||||||
|
ROP/JOP exploitation techniques. Used on aarch64.
|
||||||
|
* `-m64` and `-m32`: Some GCC builds support both 32-bit and 64-bit in
|
||||||
|
the same compilation. For such architectures, the RPM build process
|
||||||
|
explicitly selects the architecture variant by passing this compiler
|
||||||
|
flag.
|
||||||
|
|
||||||
|
In addition, `redhat-rpm-config` re-selects the built-in default
|
||||||
|
tuning in the `gcc` package. These settings are:
|
||||||
|
|
||||||
|
* **armhfp**: `-march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard`
|
||||||
|
selects an Arm subarchitecture based on the ARMv7-A architecture
|
||||||
|
with 16 64-bit floating point registers. `-mtune=cortex-8a` selects
|
||||||
|
tuning for the Cortex-A8 implementation (while preserving
|
||||||
|
compatibility with other ARMv7-A implementations).
|
||||||
|
`-mabi=aapcs-linux` switches to the AAPCS ABI for GNU/Linux.
|
||||||
|
* **i686**: `-march=i686` is used to select a minmum support CPU level
|
||||||
|
of i686 (corresponding to the Pentium Pro). SSE2 support is enabled
|
||||||
|
with `-msse2` (so only CPUs with SSE2 support can run the compiled
|
||||||
|
code; SSE2 was introduced first with the Pentium 4).
|
||||||
|
`-mtune=generic` activates tuning for a current blend of CPUs (under
|
||||||
|
the assumption that most users of i686 packages obtain them through
|
||||||
|
an x86_64 installation on current hardware). `-mfpmath=sse`
|
||||||
|
instructs GCC to use the SSE2 unit for floating point math to avoid
|
||||||
|
excess precision issues. `-mstackrealign` avoids relying on the
|
||||||
|
stack alignment guaranteed by the current version of the i386 ABI.
|
||||||
|
* **ppc64le**: `-mcpu=power8 -mtune=power8` selects a minimum
|
||||||
|
supported CPU level of POWER8 (the first CPU with ppc64le support)
|
||||||
|
and tunes for POWER8.
|
||||||
|
* **s390x**: `-march=zEC12 -mtune=z13` specifies a minimum supported
|
||||||
|
CPU level of zEC12, while optimizing for a subsequent CPU generation
|
||||||
|
(z13).
|
||||||
|
* **x86_64**: `-mtune=generic` selects tuning which is expected to
|
||||||
|
beneficial for a broad range of current CPUs. Distribution-specific
|
||||||
|
defaults for `-march=x86-64-v2` or `-march=x86-64-v3` may be
|
||||||
|
applied. The default can be overriden (for any distribution)
|
||||||
|
by specifying `--target x86_64_v2`, `--target x86_64_v3`,
|
||||||
|
`--target x86_64_v4` in the `rpmbuild` invocation.
|
||||||
|
With the GCC toolchain, TLS descriptors are enabled using
|
||||||
|
`-mtls-dialect=gnu2`.
|
||||||
|
* **aarch64** does not have any architecture-specific tuning.
|
||||||
|
|
||||||
|
### Vala-specific compiler flags
|
||||||
|
|
||||||
|
* `-g`: causes valac to emit `#line` directives in the generated C
|
||||||
|
source code. This improves backtrace generation by causing gdb to
|
||||||
|
point to Vala source file and line number instead of the generated C
|
||||||
|
source when possible.
|
||||||
|
|
||||||
|
# Individual linker flags
|
||||||
|
|
||||||
|
Linker flags end up in the environment variable `LDFLAGS`.
|
||||||
|
|
||||||
|
The linker flags listed below are injected. Note that they are
|
||||||
|
prefixed with `-Wl` because it is expected that these flags are passed
|
||||||
|
to the compiler driver `gcc`, and not directly to the link editor
|
||||||
|
`ld`.
|
||||||
|
|
||||||
|
* `-z relro`: Activate the *read-only after relocation* feature.
|
||||||
|
Constant data and relocations are placed on separate pages, and the
|
||||||
|
dynamic linker is instructed to revoke write permissions after
|
||||||
|
dynamic linking. Full protection of relocation data requires the
|
||||||
|
`-z now` flag (see below).
|
||||||
|
* `--as-needed`: In the final link, only generate ELF dependencies
|
||||||
|
for shared objects that actually provide symbols required by the link.
|
||||||
|
Shared objects which are not needed to fulfill symbol dependencies
|
||||||
|
are essentially ignored due to this flag.
|
||||||
|
* `-z pack-relative-relocs`: Use the portable `DT_RELR` scheme for
|
||||||
|
relative relocations, resulting in reduced startup time compared to
|
||||||
|
legacy architecture-specific relocations. (`-z pack-relative-relocs`
|
||||||
|
is currently disabled on aarch64 and s390x due to toolchain limitations.)
|
||||||
|
* `-z defs`: Refuse to link shared objects (DSOs) with undefined symbols
|
||||||
|
(optional, see above).
|
||||||
|
|
||||||
|
For hardened builds, some more linker options are added to the
|
||||||
|
compiler driver command line. These can be disabled by undefining the
|
||||||
|
`%_hardened_build` macro - see above.
|
||||||
|
|
||||||
|
* `-pie`: Produce a PIE binary. This is only activated for the main
|
||||||
|
executable, and only if it is dynamically linked. This requires
|
||||||
|
that all objects which are linked in the main executable have been
|
||||||
|
compiled with `-fPIE` or `-fPIC` (or `-fpie` or `-fpic`; see above).
|
||||||
|
By itself, `-pie` has only a slight performance impact because it
|
||||||
|
disables some link editor optimization, however the `-fPIE` compiler
|
||||||
|
flag has some overhead.
|
||||||
|
Note: this option is added via adding a spec file to the compiler
|
||||||
|
driver command line (`-specs=/usr/lib/rpm/redhat/redhat-hardened-ld`)
|
||||||
|
rather than using the `-Wl` mechanism mentioned above. As a result
|
||||||
|
this option is only enabled if the compiler driver is gcc.
|
||||||
|
* `-z now`: Disable lazy binding and turn on the `BIND_NOW` dynamic
|
||||||
|
linker feature. Lazy binding involves an array of function pointers
|
||||||
|
which is writable at run time (which could be overwritten as part of
|
||||||
|
security exploits, redirecting execution). Therefore, it is
|
||||||
|
preferable to turn of lazy binding, although it increases startup
|
||||||
|
time.
|
||||||
|
|
||||||
|
In addition hardened builds default to converting a couple of linker
|
||||||
|
warning messages into errors, because they represent potential
|
||||||
|
missed hardening opportunities, and warnings in the linker's output are
|
||||||
|
often ignored. This behaviour can be turned off by undefining the
|
||||||
|
`%_hardened_build` macro as mentioned above, or by undefining the
|
||||||
|
`%_hardened_linker_errors` macro. The linker options enabled by this
|
||||||
|
feature are:
|
||||||
|
|
||||||
|
* `--error-rwx-segments`: Generates an error if an output binary would
|
||||||
|
contain a loadable memory segment with read, write and execute
|
||||||
|
permissions. It will also generate an error if a thread local
|
||||||
|
storage (TLS) segment is created with execute permission. The
|
||||||
|
error can be disabled on an individual basis by adding the
|
||||||
|
`--no-warn-rwx-segments` option to the linker command line.
|
||||||
|
* `--error-execstack`: Generates an error if an output binary would
|
||||||
|
contain a stack that is held in memory with execute permission.
|
||||||
|
If a binary is being intentionally created with an executable stack
|
||||||
|
then the linker command line option `-z execstack` can be used to
|
||||||
|
indicate this.
|
||||||
|
|
||||||
|
Note: these options are added via a spec file on the compiler driver
|
||||||
|
command line (`-specs=/usr/lib/rpm/redhat/redhat-hardened-ld-errors`)
|
||||||
|
rather than using the `-Wl` mechanism mentioned above. As a result
|
||||||
|
these options are only enabled if the compiler driver is gcc. In
|
||||||
|
addition the spec file only adds the options if the `-fuse-ld=...`
|
||||||
|
option has not been enabled. This prevents the options from being
|
||||||
|
used when the gold or lld linkers are enabled.
|
||||||
|
|
||||||

# Support for extension builders
|
||||||
|
|
||||||
|
Some packages include extension builders that allow users to build
|
||||||
|
extension modules (which are usually written in C and C++) under the
|
||||||
|
control of a special-purpose build system. This is a common
|
||||||
|
functionality provided by scripting languages such as Python and Perl.
|
||||||
|
Traditionally, such extension builders captured the Fedora build flags
|
||||||
|
when these extension were built. However, these compiler flags are
|
||||||
|
adjusted for a specific Fedora release and toolchain version and
|
||||||
|
therefore do not work with a custom toolchain (e.g., different C/C++
|
||||||
|
compilers), and users might want to build their own extension modules
|
||||||
|
with such toolchains.
|
||||||
|
|
||||||
|
The macros `%{extension_cflags}`, `%{extension_cxxflags}`,
|
||||||
|
`%{extension_fflags}`, `%{extension_ldflags}` contain a subset of
|
||||||
|
flags that have been adjusted for compatibility with alternative
|
||||||
|
toolchains.
|
||||||
|
|
||||||
|
Currently the -fexceptions and -fcf-protection flags are preserved
|
||||||
|
for binary compatibility with the languages the extensions are
|
||||||
|
built against.
|
||||||
|
|
||||||
|
Extension builders should detect whether they are performing a regular
|
||||||
|
RPM build (e.g., by looking for an `RPM_OPT_FLAGS` variable). In this
|
||||||
|
case, they should use the *current* set of Fedora build flags (that
|
||||||
|
is, the output from `rpm --eval '%{build_cflags}'` and related
|
||||||
|
commands). Otherwise, when not performing an RPM build, they can
|
||||||
|
either use hard-coded extension builder flags (thus avoiding a
|
||||||
|
run-time dependency on `redhat-rpm-config`), or use the current
|
||||||
|
extension builder flags (with a run-time dependency on
|
||||||
|
`redhat-rpm-config`).
|
||||||
|
|
||||||
|
As a result, extension modules built for Fedora will use the official
|
||||||
|
Fedora build flags, while users will still be able to build their own
|
||||||
|
extension modules with custom toolchains.

Usage: gpgverify --keyring=<pathname> --signature=<pathname> --data=<pathname>
|
||||||
|
|
||||||
|
gpgverify is a wrapper around gpgv designed for easy and safe scripting. It
|
||||||
|
verifies a file against a detached OpenPGP signature and a keyring. The keyring
|
||||||
|
shall contain all the keys that are trusted to certify the authenticity of the
|
||||||
|
file, and must not contain any untrusted keys.
|
||||||
|
|
||||||
|
The differences, compared to invoking gpgv directly, are that gpgverify accepts
|
||||||
|
the keyring in either ASCII-armored or unarmored form, and that it will not
|
||||||
|
accidentally use a default keyring in addition to the specified one.
|
||||||
|
|
||||||
|
Parameters:
|
||||||
|
--keyring=<pathname> keyring with all the trusted keys and no others
|
||||||
|
--signature=<pathname> detached signature to verify
|
||||||
|
--data=<pathname> file to verify against the signature

# Decide which version of the annobin plugin for gcc should be used.
|

|
# There are two possible versions, one created by the annobin package and one
|
||||||
|
# created by the gcc package. The logic selects the gcc version unless both
|
||||||
|
# have been built by the same version of the compiler. In that case the
|
||||||
|
# annobin version is selected instead.
|
||||||
|
#
|
||||||
|
# The point of all this is that the annobin plugin is very sensitive to
|
||||||
|
# mismatches with the version of gcc that built it. If the plugin is built
|
||||||
|
# by version A of gcc, but then run on version B of gcc, it is possible for
|
||||||
|
# the plugin to misbehave, which then causes problems if gating tests examine
|
||||||
|
# the plugin's output. (This has happened more than once in RHEL...).
|
||||||
|
#
|
||||||
|
# So the plugin is built both by gcc and by the annobin package. This means
|
||||||
|
# that whenever gcc is updated a fresh plugin is built, and the logic below
|
||||||
|
# will select that version. But in order to allow annobin development to
|
||||||
|
# proceed independtently of gcc, the annobin package can also update its
|
||||||
|
# version of the plugin, and the logic will select this new version.
