nm: Fix latent memory leak in show_symbols.

2019-08-29T15:46:52+00:00

If there are just a handful of symbols then memory for them is
allocated on the stack, otherwise the memory is malloced. So before
freeing the memory we need to check the number of entries to know if
the memory was heap allocated or not. But since not all entries might
be used we might have decreased the number of entries to the number
we will actually show. Remember the original symbol entries to not
have a memory leak.

nm: Simplify naming of invalid sections, check shdr isn't NULL.

2019-04-28T15:51:06+00:00

When shdr is NULL or the sh_name index is invalid, don't try to use
it.  Just call the section "[invalid section name]". Don't try to be
too smart by creating a dynamic invalid name using alloca to simplify
memory usage in this exceptional case.

Consolidate error.h inclusion in system.h

2018-07-05T19:06:40+00:00

error.h isn't standard and so isn't part of the musl C library.
To easy future porting, consolidate the inclusion of error.h into system.h.

Move print_version into printversion.{h|c}

2017-02-17T09:55:28+00:00

Rename version.c so that the implementation is called after the header
and the header doesn't clash with the toplevel version.h. print_version
depends on argp and is only used in the tools.

Move color handling into a separate header

2017-02-15T14:24:24+00:00

We only need it in nm.c and objdump.c, but it pulls in argp as
dependency. By dropping it from libeu.h, the libraries can be
compiled without argp.

http://elfutils.org/ is now hosted at http://sourceware.org/elfutils/

2016-12-24T21:51:32+00:00

fedorahosted used to be our home, but we are now hosted at sourceware.

Change the elfutils project home to http://elfutils.org/
Point hosted services (email, release, git, bug tracker and web pages)
to https://sourceware.org/elfutils/

Move design notes from README to NOTES.
Add URLs for home, releases, bugs, git and mailinglist to README.

Make the --version output of all tools the same by using a common
print_version function and update the publicly shown copyright holder
to the elfutils developers.

lib: Provide MAX and MIN in system.h

2016-10-12T13:43:14+00:00

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.

nm: If the file is ET_REL and we need Dwarf use libdwfl to get it relocated.

2016-01-02T19:37:45+00:00

If we need Dwarf and the file is ET_REL use the same trick as in readelf
to get a relocated Dwarf. Otherwise lots of references in the debug_info
will come out as zero.

This also explains the "bogus" Dwarf seen that caused the memory leak in
the local_root that was fixed previously.

nm: Don't leak duplicate Dwarf local names.

2016-01-02T19:37:45+00:00

Badly formed DWARF can have duplicate local names. In which case we do
want to detect those so we don't leak the memory.
