Dotaz: Kompilácia starších zdrojákov.

[kysučan]

Zdravím, mám source code(lincardemu-emulácia smartcard cez rs232) cca z roku 2003. Kompilácia na súčasných distrách (ubuntu,lubuntu) mi vyhadzuje kopec chýb(a warning). Je možné nejakým nenásilnym spôsobom tie zdr. upraviť pre dnešné systémy? Podotýkam, že nie som programátorsky vybavený.

V jakém jazyku je to napsané, v C? Pokud je to napsané slušně, neměl by být problém zdroják z roku 2003 přeložit. Chtělo by samozřejmě vědět, jaké chyby to vyhodí.

[kysučan]

Je to napísané v C.

Hmm takže odpověď na to zda je ten zdroják kvalitní máme :-/.

Ve výpisu je jen jeden error, zbytek není fatální. To neznamená, že to po opravě nechcípne jinde.

conax.c:173:32: error: lvalue required as left operand of assignment
       if (v>=0) (int)caselected=in[0];   

Autor se snaží přiřadit integer číslo do proměnné typu ukazatel. Zkus v tom kódu dát před "caselected" hvězdičku. Nevím ale zda to je to co měl autor na mysli, že chce udělat.

Ostatní chyby jsou takové ty klasické "kašlu na to, funguje to", kdy se používají signed typy v unsigned použití apod.

Jsi si jistý, že neexistuje nějakej modernější soft na komunikaci? Jestli to je z roku 2003, tak to dost možná nemusí být 64bit kompatibilní.

[Michal Kubeček]

Vzhledem k tomu, jak se ta proměnná používá, měl autor spíš na mysli

    if (v >= 0)
        *(int *)&caselected = in[0]

Ale vzhledem k tomu, že proměnná je static a všude se před použitím castuje na int, nevidím důvod, proč je deklarovaná jako pointer. Ono i kdyby se v různých větvích používaly různé typy, tak od toho je union, který existoval už dlouho před rokem 2003.

[debian+]

if (v>=0) *(int *)&caselected = in[0];

ma byt

if (v>=0) caselected = in[0];

Podla: https://www.comhit.net/archive/index.php?t-32910.html

[Michal Kubeček]

Technicky to sice - s warningem - projde, ale nic to nemění na skutečnosti, že proměnná, do které se vždy ukládá int a ze které se vždy čte int, má být prostě int, ne pointer.

[debian+]

Ako dakto slavny povedal, C ti umoznuje odstralit nohu.

Este ze obycajne je, ze sizeof (void) >= sizeof(int).

[kysučan]

Nič modernejšie public nie je, iba ak .exe aplikácia Fausto, kde to je implementované asi z týchto zdrojákov. Pomohlo

 if (v >= 0)
        *(int *)&caselected = in[0]

potom

Mas vytvorit prazdny subor v lincardemu-0.21a.

Takze napr.:

touch 6805_cpu.h

Podla: https://www.comhit.net/threads/32910-Funkar-lincardemu

[kysučan]

Ok, dík, podľa tvojho odkazu kompilácia prejde...

[kysučan]

Helfne mi niekto s úpravou tohto programu?

[debian+]

Co konkretne? ... Ten program mi v pohode prelozilo.

[kysučan]

Neviem prečo, nefunguje tam jedna funkcia - ir_CAMencrypt. Ak sa zavolá, tak to ostane visieť.

[debian+]

Skor by som povedal, ze chyba nie je v kode, ale v ovladani zariadenia. Presne neviem. S takym HW skusenosti nemam. ... Nastavoval si podla toho madarskeho linku (tak pisal ako to rozbiehal)?

[kysučan]

Skôr by som povedal, že to je švédsky link. Ovládanie zar. je ok. Bez toho camcryptu mi to ide. Ale na tom camcrypte je niečo naprd, aj keď to vyzerá, že je to ok.

void ir_CAMencrypt(unsigned char *a, byte *camkey)
{ 
  char i, j;
  unsigned char t;
  unsigned char xor;
  byte keytemp[8];
  
  memcpy((byte *)keytemp, (byte *)camkey, 8);
    	
for (i = 7; i >= 0; --i) 
{
    for (j = 7; j >= 0; --j)
    {
      xor = a[6];
      xor ^= keytemp[(unsigned char)j];
      xor ^= i;
      xor = ir_table1[xor];
      t = a[7];
      a[7] = a[6];
      a[6] = a[5] ^ xor;
      a[5] = a[4];
      a[4] = a[3];
      a[3] = a[2];
      a[2] = a[1];
      a[1] = a[0];
      a[0] = t ^ xor;
    }
    ir_rotrk(keytemp);
 } 
   
}

myslím, že to mrzne na tých cykloch...

[debian+]

Pozeral som zdrojak, tj. tu funkciu. Ale nie je tam nekonecny cyklus. Je tam nastavenie pamete. Konecny dvojcyklus a xor sa pouziva sifrovanie/encryptonie alebo vypocet kontrolnych suctov a po kazdom vypocte poslane na zaredenie. Nazov funkcie je CAM znaci ir_CAMencrypt. Kluc CAM enkryptuje. Neviem, co presne. Lebo tu oblast IT nepoznam az tak. CAM

[kysučan]

Pomohla zmena char i, j; na int i, j;

[debian+]

Zaujimave. Zeby pretecenie? Ale otestoval som , ale neskoncilo mi nekonecnim cyklom. Tj. program sa ukoncil.

/* edited debian+ ir_CAMencrypt from lincardemu (GPLv2) */
#include "stdio.h"
#define byte char
void ir_CAMencrypt(unsigned char *a, byte *camkey)
{ 
  char i, j;
  unsigned char t;
  unsigned char xor;
  byte keytemp[8];
  
  //memcpy((byte *)keytemp, (byte *)camkey, 8);
    	
for (i = 7; i >= 0; --i) 
{
    for (j = 7; j >= 0; --j)
    {
      /*xor = a[6];
      xor ^= keytemp[(unsigned char)j];
      xor ^= i;
      xor = ir_table1[xor];
      t = a[7];
      a[7] = a[6];
      a[6] = a[5] ^ xor;
      a[5] = a[4];
      a[4] = a[3];
      a[3] = a[2];
      a[2] = a[1];
      a[1] = a[0];
      a[0] = t ^ xor;*/
    }
    //ir_rotrk(keytemp);
 } 
   
}

int main(int argc, char **argv)
{
	ir_CAMencrypt(0, NULL);
	return 0;
}

Ale ked pozeram na riadok:

xor ^= i;

tam mohlo pripadne zmenit vypocet kontrolneho suctu a potom nieco nesedelo, ked poslalo, tak to zostalo stat/vysiet. char ma definovanu velkost 1B, ostatne maju iba urceny minimalny rozsah.

[kysučan]

Na tej funkcii to proste končilo(nič sa neposielalo). S CRC to nemá nič, ten sa dopočitáva inak(aj keď ešte neviem kde), pre celú ins.

[debian+]

Prave v tej funkcie rata ... Vid nazov encrypt (opak je decrypt). Vid kod, tam exclusiv OR ^ (XOR zapis v C).

A program len tak zamrznut nemohol. Kto vie, aky kod je v ir_rotrk()). Ale to je jedno. Hlavne ze si opravil.

Uz vsetko ide?

Tie sa vložia do ins.(odpoveď karty/season), ku ktorej sa dopočítava 1B crc(signatúra) niekde inde v programe. Ir_rotrk je bitová rotácia a na nej to nepadalo(testované vynechaním funkcie). Problém bol jednoznačne v tom char_e, ale prečo, to musí vysvetliť nejaká múdra hlava.

Fakčí mi to zatial len v usb čítačke ovládanej oscamom, čo je len také testovacie prostr. Cieľom je rozbehať to v hw CAM_e, povedzme aj certifikovanom.

Nateraz to vidím tak, že bude potrebné sa pohrať s resetom a ATR_kom, tak ako to má vyriešené Fausto(windows apl., ktorá disponuje aj touto funkciou), kde po štarte sa čaká na reset(privedené napätie na určitý pin season interface), inak povedané zasunutie karty do CAM(čítačka). Lincardemu posiela ATR po štarte, aj keď je tam aj funkcia manual_reset...Proste ešte bude treba na tom čo porobiť.

Ak to robi chyby a fakt nevies preco, tak je zrejme poskodeny zasobnik (neuvolnanena pamet, nespravne pouzity pointer). Pouzi valgrind.

[Michal Kubeček]

Mohlo by to záležet na tom, jak překladač implementuje typ char. Pokud jako unsigned, bude podmínka "i > 0" automaticky splněná a novější překladače rovnou přeloží cyklus jako nekonečný.

[kysučan]

To by mohlo byť ono, bolo to kompilované na arm_e OPi PC. Aj podľa tejto diskusie.

[debian+]

To ma napadlo, preto som si vyskusal kod.

[Michal Kubeček]

Tohle je právě jeden z příkladů, kdy vyzkoušet nestačí, protože chování závisí na překladači. Moje doporučení je:

• Typ char používat jen tam, kde se jedná čistě o znak a neprovádím žádné aritmetické operace.
• Pokud dělám cokoli, kde by výsledek mohl záviset na tom, jestli je typ znaménkový nebo ne, explicitně deklarovat jako (un)signed char.
• Pokud hodnoty nepoužívám jako znaky ale jako osmibitová čísla, použít (u)int8_t.

[kysučan]

Potreboval by som ešte helfnúť s týmto programom. Problém spočíva v tom, že pokiaľ ho nespustím cez screen a snažím sa ho spúšťať na pozadí(napr. po štarte systému), tak neúmerne vyťažuje cpu a jeho funkčnosť nie je korektná. Ide o to, že napr. v staršom settoboxe dm500s nič také ako screen nie je(možno by šiel screen pre powerpc skompilovať, ale neviem si to dosť dobre predstaviť).

Ako inak by sa dalo tomu pomôcť? Napadá ma zakomponovanie backround funkcie priamo do programu, ale sám s tým nehnem.

[debian+]

https://packages.debian.org/jessie/powerpc/screen/download

Akej background funkcie?

[kysučan]

Dík za ten screen, ale asi si s tým nepomôžem. Vyžaduje to všeliake knižnice a nie je ich pre nedostatok miesta na flash proste kde uložiť.

Backround funkciou som myslel upraviť zdrojak tak, aby sa program spúšťal na pozadí.

[debian+]

Kolko mas volneho miesta?

Na pozadie, cize spustit ako deamon, tak to sa robi lahko v linuxe. To je v linuxe krasa. Zavolas funkciu deamon(). (toto je striktne nutne) a pripadne este pouzit 2 krat funkciu fork (prvy fork() zbavi vlastnika a druhy skupiny).

[kysučan]

V dm500s je 8MB flash, a dir /var, ktorý je read-write je možno 2MB. Nechceš načrtnúť to s tým deamon/fork?

[debian+]

V programe pouzivaj absolutne cesty.

Kod mozes pouzit vselijak. Tu mas program.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <unistd.h>

#ifndef COUNT_OUT_FILE
 #define COUNT_OUT_FILE 100
#endif

void create_file(char *path)
{
	FILE *file=NULL;
	
	if(path == NULL)
		return;
	file=fopen(path, "w");
	if(file == NULL)
		return;
	fclose(file);
}

int main(int argc, char **argv)
{
	int i;
	char path[200];
	
	if(daemon(1, 1) == -1)
	{
		fputs("Error run program as deamon().\n", stderr);
		return 1;
	}
	
	/* pocka 3 sekundy */
	sleep(3);
	
	/* vytvori COUNT_OUT_FILE praznych suborov v /tmp */
	for(i=1;i<=COUNT_OUT_FILE;i++)
	{
		snprintf(path, 200, "/tmp/files_%02d", i);
		create_file(path);
	}

	return 0;
}

Cez prikaz si mozes overit, ze ma prava vlastnika:

ps aux|grep tmp_deamon

[kysučan]

Funkciu daemon volám v main lincardemu. Ale správa sa to stále rovnako - po zavretí terminálu lincardemu síce ostáva spustený, ale začne vyťažovať cpu(90%).

Vyzerá to skôr na nejaký bug v lincardemu.

[debian+]

Inac, chyba, prva parameter deamon pouzivaj 0.

Mali hack. Vytvor deamon, ktory sa cez ssh spusti program ten a bude bezat (ne uzivatel sa prihlasi cez ssh/telnet, ale program spusteni cez telnet).

[kysučan]

Cez quazi hack to funguje, ale je to humáč...

[debian+]

:D

[debian+]

Aku mas velku RAM? Kolko jej volneho miesta?

[kysučan]

Ja to teraz testujem na ntb linux-ubuntu(2GB ram), kde sa to správa rovnako ako na tom dreamboxe. Pokiaľ to nespustím so screen_om, tak lincardemu spustený na pozadí neúmerne vyťažuje cpu.

[debian+]

Mna zaujima aku ram mas na tom routry ci co mini pc?

[kysučan]

Na dm500s je 32 MB ram.

[debian+]

a volnej? mas prava roota?

[kysučan]

Tam iný užívateľ ako root nie je. Voľnej ram tam určite veľa nie je, keď som s tým včera robil, tak myslím cca 6MB. Nakoniec som tam ten screen nejak narval, ale zbytočne. Začalo to vyhadzovať chybu ohľadom libc.so.6, a to už bolo moc aj na koňa.

[debian+]

Daj vypis:

ldd PATH_TO_SCREEN_BINARY

[kysučan]

ldd: not found

[debian+]

Preloz si screen pre danu platformu. Ale preklad daj static library. To znamena zo vsetkymi kniznicnimi zavistlostam. U mna to je 2.7 MB. Screen mal 1.8MB. GCC C kniznica 1MB.

staicky prekad

[kysučan]

Myslíš kompiláciu priamo v dreamboxe?

[debian+]

Tam by to bolo najlepsie. Ale zrejme miesta nemas, tak Ti musi stacit krizovy preklad (Křížový překladač).

P.S.: mozno aj --with-newlib by stacilo, aby sa to do ram zmestilo

[kysučan]

A ktoré zdrojaky screenu sa na to najlepšie hodia, lebo už som to skúšal https://github.com/shyouhei/screen, ale bez úspechu.

[debian+]

Oficialne ...

git clone https://git.savannah.gnu.org/git/screen.git

[debian+]

Normalna preklad

git clone https://git.savannah.gnu.org/git/screen.git
cd git
cd src
./autogen.sh
./configure
make

# spustenie
./screen

# instalacia do systemu (ako root) ... instaluje do /usr/local/bin atd.
# make install

Make instal

[kysučan]

Nepodarilo sa mi to nijak spraviť a vzdávam to. Proste skompilovať tmux alebo screen (alebo niečo podobné) pre powerpc je umenie. A s repo tmux(screen) mi to nechodí(libc.so.6 problém). Možno tomu veľa nechýba, ale nateraz, síce(ač) nerád, proste kapitulujem.

How to compile Hello World program for PowerPC (odpoved)

Najprv si skus prelozit iba hello world.

[kysučan]

To nie je problém. Napokon lincardemu s oldtoolchainom sa preloží bez komplikácií(stačí v makefile nastaviť cestu k powerpc gcc). Lenže screen(tmux) požadoval napr. libevent, alebo libncurses a to už bola pre mňa neprekonateľná prekážka.

[debian+]

Tak si preloz dtach. Odlahcene mini screen. 3 C-ckove zdrojaky. Iba C (tty) prostredie.

$ git clone https://github.com/crigler/dtach
$ cd dtach
$ ./configure
$ make CC="powerpc-linux-gnu-gcc -static"
$ du -h dtach  
724K	dtach

# sputenie program v dtach
# dtach -A PATH_SOCKET COMMAND

# priklad spustenia htop (odkusane)
./dtach -A /tmp/session1 htop

[debian+]

A pokial si zavrel kartu a chces obnovit okno, tak obnovis:

./dtach -a /tmp/session1

[kysučan]

Díky moc za tvoj záujem. Ale asi to budeme musiť vzdať.

Kompilujem to s ppcold toolchainom, pretože s repoz. gcc mi hocijaka kompilácia(lincardemu,hello_word,dtach..), aj keď prebehne ok, spustená aplikácia vyhodí segmentation fault.

A k tomu dtach_u, po chvíľke to spadne:

[EOF - dtach terminating]

[debian+]

Ak Ti ten hack funguje a staci, tak je to ok.

Pri jednom prikaze sa ku static este nieco davalo. Len to neviem najst. Napr. rozne platformu moze na rozne pozicie zarovnavat data v pamete. To by aj presnejsie chcelo vediet typ pamete, resp. dokonca ho mat.

Urcite sa to da, chce to cas (a ci to stoji za to) ...

[kysučan]

Tak najmä vďaka debian+ som to nakonie nejak dal. V main.c som vypol EXTRATIMELOOP a s dtach to už nepadá.

[debian+]

Cize dtach si nakoniec pouzil? A ako si na to prisiel, ze prave bol problem EXTRATIMELOOP?

Som rad. Ked si sa uz tolko babral s programovanim, takto nebolo zbytocne.

[kysučan]

Metóda P_O (pokus_omyl).

Najskôr som "vypol" v main.c...void sighandler_general(int sv). A nakoniec sa ukázalo, že stačilo vypnúť EXTRAT. (čo ani neviem načo je, možno na automatické save/check files).

[debian+]

v dtach kode to nie je. Ok. Tema uzavreta.

P.S.: A prvy krat som kompiloval pre powerpc.
