Description

As seen in the below disassembly, smb_inet_ntop calls the "unfixed" version:

smb_inet_ntop:                  pushq  %rbp
smb_inet_ntop+1:                movq   %rdi,%rax
smb_inet_ntop+4:                movl   %edx,%ecx
smb_inet_ntop+6:                movq   %rsp,%rbp
smb_inet_ntop+9:                pushq  %rdi
smb_inet_ntop+0xa:              pushq  %rsi
smb_inet_ntop+0xb:              pushq  %rdx
smb_inet_ntop+0xc:              movq   %rsi,%rdx
smb_inet_ntop+0xf:              movq   %rax,%rsi
smb_inet_ntop+0x12:             subq   $0x8,%rsp
smb_inet_ntop+0x16:             movl   0x10(%rdi),%edi
smb_inet_ntop+0x19:             call   +0x3acbbe2       <inet_ntop>
smb_inet_ntop+0x1e:             leave
smb_inet_ntop+0x1f:             ret

To test this, I used mdb -ke smb_inet_ntop::dis to check that correct symbol is being used:

# mdb -ke smb_inet_ntop::dis
smb_inet_ntop:                  pushq  %rbp
smb_inet_ntop+1:                movl   %edx,%ecx
smb_inet_ntop+3:                movq   %rsp,%rbp
smb_inet_ntop+6:                subq   $0x20,%rsp
smb_inet_ntop+0xa:              movq   %rdx,-0x18(%rbp)
smb_inet_ntop+0xe:              movq   %rsi,-0x10(%rbp)
smb_inet_ntop+0x12:             movq   %rsi,%rdx
smb_inet_ntop+0x15:             movq   %rdi,-0x8(%rbp)
smb_inet_ntop+0x19:             movl   0x10(%rdi),%eax
smb_inet_ntop+0x1c:             movq   %rdi,%rsi
smb_inet_ntop+0x1f:             movl   %eax,%edi
smb_inet_ntop+0x21:             call   +0x3aaaaba       <_inet_ntop>
smb_inet_ntop+0x26:             leave
