jmp-pop-call tecnique with stdin

I have written this code as an exercise to practice with jmp-pop-call shellcoding tecnique:

global _start

section .text
_start:
    jmp call_shellcode

shellcode:
    pop rsi
    ;sys_write syscall
    xor rax, rax
    mov al, 1
    xor rdi, rdi
    mov dil, 1
    xor edx, edx
    mov dl, 18
    syscall
    jmp call_shellcode2

shellcode2:
    pop rsi
    ;sys_red syscall
    xor rax, rax
    xor rdi, rdi    
    mov edx, 4
    syscall

    ; exit syscall
    xor rax, rax
    mov al, 60 ;mov rax, 60
    xor rdi, rdi ;mov rdi, 0
    add dil, 0
    syscall

call_shellcode:
    call shellcode
    welcome: db 'Insert password: ', 0xa

call_shellcode2:
    call shellcode2
    input: db 0xffffffff

The problem is the following:

$ ./simple_shellcode
Insert password: 
abc
$ abc
bash: abc: command not found

It seems that when I hit enter, the value that I inserted (plus enter) is passed to the shell. I can't understand why this happened...

Can you try to explain me the problem?

Thanks.

EDIT Here, the strace output:

execve("./BindShell", ["./BindShell"], 0x7fff3b5e0d00 /* 49 vars */) = 0
write(1, "Insert password: \n", 18Insert password: 
)     = 18
read(0, 123 
0x40104f, 4)                    = -1 EFAULT (Invalid address)
exit(0)                                 = ?
+++ exited with 0 +++

As Peter Cordes said in the comments the read function returns -1 EFAULT and assembling it with --omagic option it works fine. Now my question is: is a clean solution use that option using jmp-pop-call technique?
