Separate reader and writer
jrmadsen opened this issue · comments
Hi, I've been experimenting with ELFIO and I have more-or-less trying to read in an ELF and the write out again using a separate instance of ELFIO::elfio but there appears to be an issue with the headers.:
// error checking and asserts omitted in the interest of brevity
using Section = ELFIO::section;
using Segment = ELFIO::segment;
void read_write(std::string in, std::string out)
{
ELFIO::elfio reader{};
ELFIO::elfio writer{};
reader.load(in);
writer.create(reader.get_class(), reader.get_encoding());
writer.set_os_abi(reader.get_os_abi());
writer.set_type(reader.get_type());
writer.set_machine(reader.get_machine());
writer.set_abi_version(reader.get_abi_version());
std::vector<std::pair<Section*, Section*>> _sections{};
std::vector<std::pair<Segment*, Segment*>> _segments{};
for(size_t i = 0; i < reader.sections.size(); ++i)
_sections.emplace_back(reader.sections[i],
writer.sections.add(reader.sections[i]->get_name()));
for(size_t i = 0; i < reader.segments.size(); ++i)
_segments.emplace_back(reader.segments[i], writer.segments.add());
for(auto& itr : _sections)
{
auto* _read = itr.first;
auto* _write = itr.second;
_write->set_type(_read->get_type());
_write->set_flags(_read->get_flags());
_write->set_addr_align(_read->get_addr_align());
_write->set_link(_read->get_link());
_write->set_info(_read->get_info());
_write->set_entry_size(_read->get_entry_size());
_write->set_name_string_offset(_read->get_name_string_offset());
_write->set_data(_read->get_data(), _read->get_size());
}
for(auto& itr : _segments)
{
auto* _read = itr.first;
auto* _write = itr.second;
_write->set_type(_read->get_type());
_write->set_flags(_read->get_flags());
_write->set_align(_read->get_align());
for(size_t i = 0; i < _read->get_sections_num(); ++i)
{
Section* _read_sec = reader.sections[_read->get_section_index_at(i)];
auto witr =
std::find_if(writer.sections.begin(), writer.sections.end(),
[_read_sec](const ELFIO::section* _wsec) {
return _wsec->get_name() == _read_sec->get_name();
});
Section* _write_sec = *witr;
_write->add_section(_write_sec, _write_sec->get_addr_align());
}
}
writer.set_entry(reader.get_entry());
writer.save(_out);
}However, the ELF is invalid. Here is a diff of readelf -a -W exe vs. readelf -a -W exe.mod:
$ readelf -a -W ./exe &> dump.exe && readelf -a -W ./exe.mod &> dump.exe.mod && diff -y -W 200 ./dump.exe ./dump.exe.mod

GNU 0x00000010 NT_GNU_ABI_TAG (ABI version tag) OS: Linux, A GNU 0x00000010 NT_GNU_ABI_TAG (ABI version tag) OS: Linux, AI've read the docs pretty thoroughly and looked at several of the examples and tests and it doesn't appear to me that there is any significant part of the API that I am ignoring when copying things over to the writer (there are a few minor things like the segment file/memory size but nearly everything I excluded was bc they were causing validation or write errors at some point).
Hi @jrmadsen ,
A simpler way to copy ELF file would be:
ELFIO::elfio reader;
reader.load(in);
reader.save(out);
@serge1 yes, that possibility was not lost on me. The objective of this exercise was to validate that I could assemble a valid ELF file from the components, not just copy it. In practice, I am going to be interacting with a compiler API and will need to essentially do something along the lines of the highly simplified model I provided here
By the way, I'm happy to fix this issue myself. Not expecting you to, just looking for insight or at least guesses about what is going wrong.
I am going to look at the differencies. The first think coming is that creating a new instance of 'elfio' automatically creates a couple of required sections. Those sections are duplicated again when the full list of sections is copied.
The second aspect I would look at is the segments memory layout. When elfio creates a segment layout, it obeys the visible section align rules. It might be different from the memory layout used by the original file. In the last case, all reallocations will be shifted. This will lead to an incorrect output file image.
Please also look at https://github.com/serge1/ELFIO/wiki/How-to-modify-section-data
As for the pair 'load+save', the library makes special effort trying to remember original offsets. It is not 100% solution too, but, it works in some basic cases.
If you are going to work with a compiler API, most likely, you will work with not linked object files. In such case, the things become much easy.
Those segments are duplicated again when the full list of sections is copied.
Due to automatically inserted sections, all the 'link' fields from the original file are become invalid. In particular, this leads to incorrect relocations during loading process.
Yet another advice - you may check equivalence of two ELF files by using functions similar to checkObjestsAreEqual() and checkExeAreEqual() located in tests/ELFIOTest1.cpp.
Let me know if you have further doubts
Those segments are duplicated again when the full list of sections is copied.
Due to automatically inserted sections, all the 'link' fields from the original file are become invalid. In particular, this leads to incorrect relocations during loading process.
Similarly, due to a different order of sections insertion, section header string table cannot be reused "as is". All string pointers become invalid.
NULL section should not be copied again
@serge1 Thank you for all your insight. I had to make segment::set_offset public to finally get it working. Here is the final simplified workflow:
using Section = ELFIO::section;
using Segment = ELFIO::segment;
void read_write(std::string in, std::string out)
{
ELFIO::elfio reader{};
ELFIO::elfio writer{};
reader.load(in);
writer.create(reader.get_class(), reader.get_encoding());
writer.set_os_abi(reader.get_os_abi());
writer.set_type(reader.get_type());
writer.set_machine(reader.get_machine());
writer.set_abi_version(reader.get_abi_version());
writer.set_entry(reader.get_entry());
std::vector<std::pair<Section*, Section*>> _sections{};
std::vector<std::pair<Segment*, Segment*>> _segments{};
std::map<ELFIO::Elf_Word, ELFIO::Elf_Word> _section_index_mapping = { { 0, 0 } };
for(size_t i = 0; i < reader.sections.size(); ++i)
{
Section* _read = reader.sections[i];
if(_read->get_name().empty())
continue;
auto itr = std::find_if(
writer.sections.begin(), writer.sections.end(),
[_read](const Section* _v) { return _v->get_name() == _read->get_name(); });
_sections.emplace_back(_read, (itr == writer.sections.end())
? writer.sections.add(_read->get_name())
: *itr);
}
for(size_t i = 0; i < reader.segments.size(); ++i)
_segments.emplace_back(reader.segments[i], writer.segments.add());
for(auto& itr : _sections)
_section_index_mapping.emplace(itr.first->get_index(), itr.second->get_index());
for(auto& itr : _sections)
{
auto* _read = itr.first;
auto* _write = itr.second;
_write->set_name(_read->get_name());
_write->set_type(_read->get_type());
_write->set_flags(_read->get_flags());
_write->set_address(_read->get_address());
_write->set_addr_align(_read->get_addr_align());
_write->set_link(_section_index_mapping.at(_read->get_link()));
_write->set_info(_read->get_info());
_write->set_name_string_offset(_read->get_name_string_offset());
_write->set_entry_size(_read->get_entry_size());
if(_write->get_name() != ".bss")
_write->set_data(_read->get_data(), _read->get_size());
else
_write->set_size(24);
}
for(auto& itr : _segments)
{
auto* _read = itr.first;
auto* _write = itr.second;
_write->set_type(_read->get_type());
_write->set_flags(_read->get_flags());
_write->set_align(_read->get_align());
_write->set_virtual_address(_read->get_virtual_address());
_write->set_physical_address(_read->get_physical_address());
_write->set_offset(_read->get_offset());
for(size_t i = 0; i < _read->get_sections_num(); ++i)
{
Section* _read_sec = reader.sections[_read->get_section_index_at(i)];
Section* _write_sec =
writer.sections[_section_index_mapping.at(_read_sec->get_index())];
_write->add_section(_write_sec, _write_sec->get_addr_align());
}
}
writer.save(out);
