* Check for -z,defs, -z,relro, -fPIC, -fPIE before using themUlf Hermann2017-08-182-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | Those flags are not available on all platforms, and omitting them when not available will not cause any harm. In particular: -z,defs disallows undefined symbols in object files. This option is unsupported if the target binary format enforces the same condition already. Furthermore it is only a compile time sanity check. When it is omitted, the same binary is produced. -z,relro instructs the loader to mark sections read-only after loading the library, where possible. This is a hardening mechanism. If it is unavailable, the functionality of the code is not affected in any way. -fPIC instructs the compiler to produce position independent code. While this is preferable to relocatable code, relocatable code also works and may even be faster. Relocatable code might just be loaded into memory multiple times for different processes. -fPIE is the same thing as -fPIC for executables rather than shared libraries.

Add URLs for home, releases, bugs, git and mailinglist to README.

* Add GCC7 -Wimplicit-fallthrough support/fixes.Mark Wielaard2016-11-102-1/+12
| | | | | | | | | | | GCC7 will have a new -Wimplicit-fallthrough warning. It did catch one small buglet in elflint option procession. So it seems useful to enable to make sure all swatch case fallthroughs are deliberate. Add configure check to detect whether gcc support -Wimplicit-fallthrough and enable it. Add fixes and explicit fallthrough comments where necessary. Signed-off-by: Mark Wielaard <mjw@redhat.com>

| | | | | | | | | Both -Wlogical-op and -Wduplicated-cond may produce useful warnings. But we have to check them first. Older versions of gcc had a -Wlogical-op that warned on some constructs using macros that are not erronious. Only GCC6 has -Wduplicated-cond. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* config: Use ARFLAGS 'cr'.Mark Wielaard2015-10-122-0/+8
| | | | | | | | | | | | | | | By default automake uses ARFLAGS cru. 'u' is an optimization that makes sure files are only added to the archive when they are newer than the version already in the .a file. This optimization doesn't work when ar is deterministic by default because then it doesn't record timestamps in the archive. Deterministic ar is the default now on various distributions causing multiple warnings like: ar: `u' modifier ignored since `D' is the default (see `U') To suppress these warnings drop the 'u' flag.

* Trust AC_SYS_LARGEFILE to provide large file supportJosh Stone2015-10-092-0/+7
| | | | | | | | | | | | | | | AC_SYS_LARGEFILE defines _FILE_OFFSET_BITS in config.h if needed for LFS, and this automatically maps things like open to open64. But quite a few places used explicit 64-bit names, which won't work on platforms like FreeBSD where off_t is always 64-bit and there are no foo64 names. It's better to just trust that AC_SYS_LARGEFILE is doing it correctly. But we can verify this too, as some file could easily forget to include config.h. The new tests/run-lfs-symbols.sh checks all build targets against lfs-symbols (taken from lintian) to make sure everything was implicitly mapped to 64-bit variants when _FILE_OFFSET_BITS is set.

* Improve AM_SILENT_RULES coverageJosh Stone2015-10-062-2/+6
| | | | | | | | | | | Note, elfutils does not explicitly enable AM_SILENT_RULES. It's only available starting from automake 1.11, but starting from automake 1.13 silent rules are always generated, defaulting to verbose. $(AM_V_foo) additions should be no-ops on systems that don't support silent rules. To be silent, use "./configure --enable-silent-rules" or "make V=0". Signed-off-by: Josh Stone <jistone@redhat.com>

* spec: Provide default-yama-scope.Mark Wielaard2015-08-044-2/+69
| | | | | | | | | | | | | | | | | | | | When yama is enabled in the kernel it might be used to filter any user space access which requires PTRACE_MODE_ATTACH like ptrace attach, access to /proc/PID/{mem,personality,stack,syscall}, and the syscalls process_vm_readv and process_vm_writev which are used for interprocess services, communication and introspection (like synchronisation, signaling, debugging, tracing and profiling) of processes. These are precisely the things that libdw dwfl and ebl backends rely on. So make sure they don't mysteriously fail in such cases by providing the default yama scope sysctl value. This is implemented as a separate subpackage that just provides this functionality so other packages that don't directly rely on elfutils-libs can also just Requires: default-yama-scope to function properly. https://bugzilla.redhat.com/show_bug.cgi?id=1209492#c69 Signed-off-by: Mark Wielaard <mjw@redhat.com>

* Allow disabling symbol versioning at configure timeMax Filippov2015-04-232-2/+12
| | | | | | | | | | | | | Due to missing symbol versioning support in uClibc calls to versioned functions that internally call different version of themselves results in infinite recursion. Introduce macro SYMBOL_VERSIONING and use it instead of plain SHARED to decide whether symbol versioning is needed.

| | | | | | | | | | | | | | | Using american fuzzy lop has found a lot of issues. It would be nice to make using it a bit easier. Our build files make sure that no shared library uses text relocations, but afl-gcc will insert some on i686. http://www.akkadia.org/drepper/textrelocs.html Now CC=afl-gcc ./configure --disable-textrelcheck will allow them so that afl can instrument the libraries. Don't try to use or install them except with afl-fuzz. When selinux is enabled it might prevent loading the libraries with DT_TEXTREL set. Signed-off-by: Mark Wielaard <mjw@redhat.com>
