"Чтение/запись в железный порты (outb() / inb())"
Отправлено TLS , 23-Мрт-06 18:55

Была у меня прога, которая внаглую запускалась из-под рута и писала в хардварные порты при помощи функция outb() и читала с помощью inb(). Работала один-в-один с описанным здесь примером: http://www.opennet.me/openforum/vsluhforumID9/1386.html#1
Но сейчас аналогичный код работать отказывается. Единственное объяснение, которое вижу - смена версий с FreeBSD 4.9 до 6.0. Это можнт быть причиной? Если да, то чего посоветуете делать?
Спасибо!

kldload io
or
device io в конфиг ядра + пересобрать ядро.

>kldload io
Странно, но при запуске команды (или функции из проги) из-под рута, всё равно выдает Not permitted.

kldstat -v в студию

Да загрузился модуль-то наверняка, только этого мало.
Надо еще в самой программе открыть файл /dev/io, только тогда iopl установится. А вообще и это неправильно - правильно будет пользовать i386_set_ioperm(2).

человек берет готовую программу, там уже есть open("/dev/io",..)

первый deprecated, но _неправильным_ от этого не становится.

Меня тоже это зинтересовало но у меня на freebsd6.0 это вообще не собирается в чем может быть косяк
вот эта прога я скопировал
#include <stdio.h>
#include <fcntl.h>
#include <machine/cpufunc.h>
int main(int argc,char* argv[])
{
int val,port;
int fd;
if(argc<3){fprintf(stderr,"usage: %s port value\n",argv[0]); exit(1);}
if(sscanf(argv[1],"0x%x",&port) && sscanf(argv[2],"0x%x",&val))
{
fd=open("/dev/io",O_RDWR);
if(fd==-1){perror("open");exit(1);}
outb(port,val);
close(fd);
}
else
{fprintf(stderr,"port and value must be in hex format with 0x prefix\n"); exit(1);}
}
компилируем:
# gcc outb.c -o outb
запускаем:
# ./outb 0x3f2 0x10
лампочка дисковода загорелась
# ./outb 0x3f2 0x0
потухла

В FreeBSD нет ioperm(). Уже говорили: /dev/io || i386_set_ioperm() и баста.
