2017-07-14binutils/objdump: Fix disassemble for huge elf sectionsRavi Bangoria1-3/+3
When elf section size is beyond unsigned int max value, objdump fails to disassemble from that section. Ex on PowerPC, $ objdump -h /proc/kcore Idx Name Size VMA 4 load2 100000000 c000000000000000 Here, size of load2 section is 0x100000000. Also note that, 0xc00.... address range is kernel space for PowerPC. Now let's try to disassemble do_sys_open() using /proc/kcore. $ cat /proc/kallsyms | grep -A1 -w do_sys_open c00000000036c000 T do_sys_open c00000000036c2d0 T SyS_open Before patch: $ objdump -d --start-address=0xc00000000036c000 --stop-address=0xc00000000036c2d0 /proc/kcore /proc/kcore: file format elf64-powerpcle Disassembly of section load2: c00000000036c000 <load2+0x36c000>: c00000000036c000: Address 0xc00000000036c000 is out of bounds. Fix this by changing type of 'buffer_length' from unsigned int to size_t. After patch: $ objdump -d --start-address=0xc00000000036c000 --stop-address=0xc00000000036c2d0 /proc/kcore /proc/kcore: file format elf64-powerpcle Disassembly of section load2: c00000000036c000 <load2+0x36c000>: c00000000036c000: fc 00 4c 3c addis r2,r12,252 c00000000036c004: 00 53 42 38 addi r2,r2,21248 c00000000036c008: a6 02 08 7c mflr r0 include/ * dis-asm.h (struct disassemble_info): Change type of buffer_length field to size_t. opcodes/ * dis-buf.c (buffer_read_memory): Change type of end_addr_offset, max_addr_offset and octets variables to size_t.
