uboot - fw_printenv / fw_setenv / fw_getenv ethaddr 제약사항

fw_printenv는 uboot에 포함된 tool이다
uboot/tool/env 에 존재하는 녀석인데
ethaddr을 값을 변경하려고 하니 에러가 발생하였다.

fw_setenv()의 리턴값은 30인데 아마도 EROFS가 30인듯 하다(errno.h에서는 발견하지 못한 변수이다.)
눈에 들어온 부분은 아래의 strcmp() 이다.

	/*
	 * Delete any existing definition
	 */
	if (oldval) {
		/*
		 * Ethernet Address and serial# can be set only once
		 */
		if ((strcmp (name, "ethaddr") == 0) ||
			(strcmp (name, "serial#") == 0)) {
			fprintf (stderr, "Can't overwrite \"%s\"\n", name);
			return (EROFS);
		}

		if (*++nxt == '\0') {
			*env = '\0';
		} else {
			for (;;) {
				*env = *nxt++;
				if ((*env == '\0') && (*nxt == '\0'))
					break;
				++env;
			}
		}
		*++env = '\0';
	}

아무튼, uboot에서 기본적으로 ethaddr과 serial#을 지원하고
이값들은, 한번만 write되고 수정되서는 안되기 때문에 제약사항으로 묶어놓은 듯 하다.

ifup / ifdown + busybox

busybox에서 라고 해야 하나,
아무튼, busybox의 경우에는 커널에서 부팅시에 ip를 설정한다.

머.. 이건 중요한게 아니고, 아무튼, ifdown을 통해서 죽이고
ifup을 통해서 올리려고 하는데, ifup시 static ip가 설정이 되지 않고
초기 kernel argument로 넘긴 값으로 부팅이 되는 문제가 있다.

Re: ETH0 already configured durring boot

The U-boot uses its own network driver and only the MAC address set up by the U-boot affects the network driver under Linux.

The network is started by the script /etc/init.d/networking in Debian/Emdebian distribution. The soft links are used in each run level start up directories /etc/rcX.d, where X is run level 0, 1, 2, etc. The normal run level is 3. You can remove the link in the directory to disable the network start up.

The text file /etc/network/interfaces configures the network interfaces. It should be something like,

auto eth0
iface eth0 inet dhcp

You can also just remove everything in this file to disable the automatic start up of the network.

/etc/network/interfaces는 ifup / ifdown 에서 사용하는 내용으로 저러면 된다는데...
결국 미궁이다.. 후우...

busybox ash 주의사항?

어쩌면 당연한걸지도 모르겠지만..
리눅스와 윈도우의 개행은 CR+LF / LF로 차이가 크다.

vi에서 보면
CR+LF는 ^M이 붙는데,
이로 인해서 쉘에서 인식을 제대로 못하고
실행을 못하는 문제가 생긴다.

bash에서는 문제가 없었던거 같은데.. 흐음..
아무튼 busybox에서 사용하는 ash의 경우에는 CR+LF의 경우에는
제대로 안되니 반드시 확인을 해야한다.

(이걸로 일주일 공쳤네 ㄱ-)

비지박스 핑간격 조절하기 - busybox ping interval

제목이랑은 조금 심하게 다르지만..

busybox-1.10.1/networking/ping.c 의 소스를 보면

enum {
    DEFDATALEN = 56,
    MAXIPLEN = 60,
    MAXICMPLEN = 76,
    MAXPACKET = 65468,
    MAX_DUP_CHK = (8 * 128),
    MAXWAIT = 10,
    PINGINTERVAL = 1, /* 1 second */
};

라는 부분에 timeout 10초와 핑간격 1초가 정의되어 있다.
어짜피 alarm() 함수가 integer 만 받아서 소수점은 무리이므로
ping -c 를 이용하여 빠르게 핑 테스트는 힘들듯 하다.

다른 방법으로 접근을 하자면,
ping -c 1 ... ; ping -c 1 ...
이런식의 명령행으로 할 경우 1초 간격없이 빠르게 핑을 연속으로 보낼 수 있다.

awk / sed / regular expression

awk의 가장 유용한 사용방법은
awk '{print $1}' 가 아닐까 생각이 된다.
일단 1번부터 시작하여 n 번째의 문자열을 출력해주며
문자열은 공백으로 구분한다.

예를 들어
/proc/cmdline의 경우

$ cat /proc/cmdline
ro root=/dev/VolGroup00/LogVol00 rhgb quiet

인데 awk를 사용할 경우

$ cat /proc/cmdline | awk '{print $1}'
ro
$ cat /proc/cmdline | awk '{print $2}'
root=/dev/VolGroup00/LogVol00
$ cat /proc/cmdline | awk '{print $3}'
rhgb
$ cat /proc/cmdline | awk '{print $4}'
quiet
$ cat /proc/cmdline | awk '{print $5}'

이런식으로 구분을 하여 옵션별로 떼어낼 수 있다.

$ cat /proc/cmdline | awk '{print NF}'
4

NF는 내부 변수로 컬럼의 갯수를 알려준다.

Busybox build option - "Build BusyBox as a static binary (no shared libs)"

menu 'Build Options'

config CONFIG_STATIC
    bool "Build BusyBox as a static binary (no shared libs)"
    default n
    help
    If you want to build a static BusyBox binary, which does not
    use or require any shared libraries, then enable this option.
    This can cause BusyBox to be considerably larger, so you should
    leave this option false unless you have a good reason (i.e.
    your target platform does not support shared libraries, or
    you are building an initrd which doesn't need anything but
    BusyBox, etc).

    Most people will leave this set to 'N'.

비지박스를 컴파일 하면, 용량이 생각보다 크다.
이 경우에는 위의 옵션을 꺼주면 컴팩트해진다.

1.10.4 기준으로 1.6M에서 600K 정도로 용량이 줄어드는데,
확신할 수는 없지만, 이 옵션을 사용했기 때문에 DNS resolv를 하지 못하는 것 같다.
busybox에서 ping이나 telnet 이 resolv 실패가 뜨면

libresolv.so
libdns.so

를 복사 해주면 되는데, 이 옵션의 영향이 아닐까 생각이된다.
