| * libcpu: Recognize bpf jump variants BPF_JLT, BPF_JLE, BPF_JSLT and BPF_JSLEMark Wielaard2018-11-092-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux kernel 4.13 introduced 4 more jump class variants. commit 92b31a9af73b3a3fc801899335d6c47966351830 Author: Daniel Borkmann <daniel@iogearbox.net> Date: Thu Aug 10 01:39:55 2017 +0200 bpf: add BPF_J{LT,LE,SLT,SLE} instructions For conditional jumping on unsigned and signed < and <= between a register and another register or immediate. Add these new constants to bpf.h, recognize them in bpf_disasm and update the testfile-bpf-dis1.expect file. Signed-off-by: Mark Wielaard <mark@klomp.org>

| * Use fallthrough attribute.Joshua Watt2018-02-102-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use __attribute__ ((fallthrough)) to indicate switch case fall through instead of a comment. This ensures that the fallthrough warning is not triggered even if the file is pre-processed (hence stripping the comments) before it is compiled. The actual fallback implementation is hidden behind a FALLBACK macro in case the compiler doesn't support it. Finally, the -Wimplict-fallthrough warning was upgraded to only allow the attribute to satisfy it; a comment alone is no longer sufficient. Signed-off-by: Joshua Watt <JPEWhacker@gmail.com>
| * Make sure packed structs follow the gcc memory layoutUlf Hermann2017-09-202-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc defaults to using struct layouts that follow the native conventions, even if __attribute__((packed)) is given. In order to get the layout we expect, we need to tell gcc to always use the gcc struct layout, at least for packed structs. To do this, we can use the gcc_struct attribute. This is important, not only for porting to windows, but also potentially for other platforms, as the bugs resulting from struct layout differences are rather subtle and hard to find.

| * Check for -z,defs, -z,relro, -fPIC, -fPIE before using themUlf Hermann2017-08-182-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * backends: Don't depend on linux/bpf.h to compile bpf disassembler.Mark Wielaard2017-07-243-8/+7
| | | | | | | | | | | | | | | | | | We only need a few constants and one structure definition from linux/bpf. Just define those in a local lib/bpf.h file. This makes sure the bpf disassembler is always build and included even when elfutils is build on older GNU/Linux systems (and even on other platforms). Signed-off-by: Mark Wielaard <mark@klomp.org>

* | Make sure packed structs follow the gcc memory layoutUlf Hermann2017-05-021-1/+1
| | | | | | | | | | | | | | | | On windows gcc by default generates code that follows the MSVC layout. We don't want that as it adds extra padding. Change-Id: I92efe5da2a2ad818783707ee96a9b8e0eb606dbd Reviewed-by: Christian Kandeler <christian.kandeler@qt.io>

| | | | | | | | | | | | | | | | | | | | This enables us to build a fully featured elfutils package on systems with reduced C libraries, such as windows. All the modules are built into libgnu.a, which is then linked into all binaries if --enable-gnulib is given on the configure line.

* Add GCC7 -Wimplicit-fallthrough support/fixes.Mark Wielaard2016-11-102-2/+6
| | | | | | | | | | | 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>
* lib: Provide MAX and MIN in system.hAkihiko Odaki2016-10-124-3/+8
| | | | | | | | | | This change also creates a new header file libeu.h to provide the prototypes for the function of libeu. That hides the definition of function crc32, which can conflict with zlib, from libelf. It also prevents mistakes to refer those functions from a component which doesn't link with libeu, such as libelf. Signed-off-by: Akihiko Odaki <akihiko.odaki.4i@stu.hosei.ac.jp>

| | | | | | | | | | | 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>

* Remove mudflap build option.Mark Wielaard2014-04-182-1/+5
| | | | | | | | | The --enable-mudflap configure build has been broken for 2 years without anybody apparently noticing. GCC 4.9 removed mudflap support.
