So Rebuilder

This is a tool target at .so file repair, which section header has been damaged.

Temporarily support 32bits-so-file.

About this project

To rebuild the section header. I learning a way to rebuild by the information of segment and .dynamic section from ThomasKing's article https://bbs.pediy.com/thread-192874.htm .

Some reference articles I have placed in directory reference .

And my ideas and some basing knowledge have placed in directory thinking .

Some damaged so-file placed at test using for program testing.

Usage

You can run make command to compile this project. Then using ./sb -h to see the help.

The default compile environment is 32bits. If you want to compile 64bits version, you can run make v=64. What a shame that it doesn't support 64bits-so-file yet.

usage: sb <file.so>
       sb <file.so> -o <repaired.so>

option: 
    -o --output <outputfile>   Specify the output file name. Or append "_repaired" default.
    -c --check                 Check the damage level and print it.
    -f --force                 Force to fully rebuild the section.
    -m --memso <baseAddr(hex)> Source file is dump from memory from address x(hex)
    -v --verbose               Print the verbose repair information
    -h --help                  Print this usage.
    -d --debug                 Print this program debug log.

The most common use is ./sb -c -d -v <file.so>. You can see all message output from repairing. The program may have bugs. Sometime it may have a wrong complete detection at damaged so-file. So I add a parameter. You can use -f or --force force to rebuild the so-file.
