  1. I believe you’re looking for:

    info symbol <addresss>

    Print the name of a symbol which is stored at the address addr. If no symbol is stored exactly at addr, GDB prints the nearest symbol and an offset from it.

    Example:

    (gdb) info symbol 0x400225 _start + 5 in section .text of /tmp/a.out  (gdb) info symbol 0x2aaaac2811cf __read_nocancel + 6 in section .text of /usr/lib64/libc.so.6

    You can read more about it here.
