LIEF:修改安卓.so后报 dlopen failed:has invalid shdr offset/size

1. Start of section headers 的值必须 32 字节对齐。
2. 使用 readelf -h lib.so 查看 Start of section headers 的值。

   ELF Header:
     Magic:   7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00
     Class:                             ELF64
     Data:                              2's complement, little endian
     Version:                           1 (current)
     OS/ABI:                            UNIX - System V
     ABI Version:                       0
     Type:                              DYN (Shared object file)
     Machine:                           AArch64
     Version:                           0x1
     Entry point address:               0xc6f0
     Start of program headers:          64 (bytes into file)
     Start of section headers:          381358 (bytes into file)
     Flags:                             0x0
     Size of this header:               64 (bytes)
     Size of program headers:           56 (bytes)
     Number of program headers:         9
     Size of section headers:           64 (bytes)
     Number of section headers:         25
     Section header string table index: 24
   

3. 比如我这里是 381358，十六进制为 0x5D1AE，需要填充两字节 00 使其对齐。
4. 对齐后的地址为 0x5D1B0，在文件偏移 0x28 处修改为相应的值。
