* | Handle invalid symbol table entries that refer to non-existent sectionsEelco Dolstra2014-01-141-3/+8
|/ | | | | | | | For instance, libcairo-swt.so from Eclipse SDK 4.2.2 has entries like: 30: 0000000000000000 0 SECTION LOCAL DEFAULT 30 even though there is no section 30. So ignore these.

| | | | | | | This allows removing the specified DT_NEEDED entries from the dynamic section. Closes #4.

* Rewrite the st_shndx field in symbol tablesEelco Dolstra2012-08-211-4/+29
| | | | | | | The st_shndx field in symbol tables specifies the index of the section that contains the symbol. Since we reorder sections, we need to update this field as well. Otherwise programs like gdb won't be able to resolve addresses to symbol names (and will print "?? ()" instead).

* * Support executables created by the Gold linker (NixOS/140). TheseEelco Dolstra2011-09-111-5/+40
| | | | | | | | | | | | are marked as ET_DYN (not ET_EXEC) and have a starting virtual address of 0 so they cannot grow downwards. In order not to run into a Linux kernel bug, the virtual address and the offset of the new PT_LOAD segment have to be equal; otherwise ld-linux segfaults. To ensure this, it may be necessary to add some padding to the executable (potentially a lot of padding, if the executable has a large uninitialised data segment). * Use size_t rather than off_t in some places.

* * A first attempt at --set-rpath support for libraries. This is veryEelco Dolstra2008-05-281-3/+170
| | | | | | | | | | useful for the NVIDIA libGL.so, since setting an RPATH on libGL.so to include its dependencies (like libXext and libGLcore) makes it unnecessary to set an RPATH on the executables that use it. This is especially important for executables that use RUNPATH (like Wine) since there the paths in RUNPATH are ignored when resolving the dependencies of dependencies (i.e. RUNPATH is scoped).
