Hi ALL,
Could you help me how to give the execute permissions to data segment which
have already read write permission.
Actually I want to change the permission of data segment in shared
object(ld.so.1 as well as some shared objects) using gcc linker script.
If you have another idea except linker script,please share.
following are my output of elfdump.
Program Header[0]:
p_vaddr: 0 p_flags: [ PF_X PF_R ]
p_paddr: 0 p_type: [ PT_LOAD ]
p_filesz: 0x2af6c p_memsz: 0x2af6c
p_offset: 0 p_align: 0x8000
Program Header[1]:
p_vaddr: 0x33010 p_flags: [ PF_W PF_R ]
p_paddr: 0x33010 p_type: [ PT_LOAD ]
p_filesz: 0xa2b p_memsz: 0x24d4
p_offset: 0x2b010 p_align: 0x8000
above Program Header[1]: is for code segment so I want change
p_flags: [ PF_W PF_R ] to p_flags: [ PF_X PF_W PF_R ]
Thanks & Regards
verma
