Temat: Technicolor TC7200 i mod firmware'u

Witam wszystkich forumowiczów!
Ostatnio NETIA mnie trochę rozwścieczyła, ale oszczędzę szczegółów.

Jak w temacie. Chciałbym maksymalnie obciąć oprogramowanie routera (SNMP z wewnątrz (LAN) i zewnątrz (NETIA) i http, bo zazwyczaj tam znajduje się najwięcej błędów. Jeżeli się mylę, proszę mnie poprawić) i wycisnąć z niego wszystko co się da. Ma 5GHz, bez ac co prawda, ale lepsze to niż nic. O OpenWrt/LEDE nawet nie marzę, bo: 1. musiałbym wgrać custom bootloader (Nie chcę stracić kontroli nad Technicolorem. Jeżeli bootloader odmówi działania, jestem w kropce, bo jest na kości NAND, do której nie mam programatora). 2. Obecność modemu DOCSIS.

Moje obserwacje i wnioski:

Zauważyłem, że w routerze o dziwo znajdują się 2 flashe:

...
SPI flash ID 0xc22014, size 1MB, block size 64KB, write buffer 256, flags 0x0
NAND flash: Device size 64 MB, Block size 16 KB, Page size 512 B
Cust key size 128
parameter offset is 43872

Signature/PID: a822

Reading flash map at ff30, size 192
Successfully restored flash map from SPI flash!
...

Po dalszej inspekcji okazało się, że może być więcej połączeń RS232 (interesuje mnie tty0):

...
Init device '/dev/tty0'
Init tty channel: 816a8518
...

Rzeczywiście na płycie znajdują się 2 seriale: 1 jest do kontroli bootloadera, a 2 zostało schowane pod radiatorem. Po podpięciu się do niego 2 igłami i GND od bootloadera, ujrzałem log ze startu kernela (czyli jest to /dev/tty0). Po starcie systemu odpala się /bin/login.


Mam następujące pytania:
Pytanie 1: Czy ktoś potrafi określić do czego dokładnie flash SPI służy? Tylko do przechowywania mapy partycji z NANDu, czy może do czegoś jeszcze?

Pytanie 2: Niestety, nie znam hasła root'a. Chciałem zdumpować NAND przez bootloader, ale ten nie daje możliwości czytania niczego z adresem mniejszym niż 0x8000000. Natomiast z logów wynika, że firmware jak i kernel są rozpakowywane na adresach dostępnych do odczytania. Czy możliwa jest operacja, w której czekam aż obydwa obrazy się rozpakują, restart, i dump adresów z rozpakowanymi obrazami?

Pytanie 3: Jak mogę wykonać dump'a aktualnego firmware? Mogę to oczywiście zrobić z poziomu konsoli (po odnalezieniu hasła root'a), ale chciałbym mieć pewność, że do kości nic nie pisze. Bootloader daje możliwość zgrania obrazu przez TFTP do RAM i  odpalenie go (jak to każdy normalny bootloader). Może ktoś ma jakiś initram współpracujący z tym SoCem?

Pytanie 4: W przypadku braku możliwości zgrania danych z NAND, czy mogę zmusić modem DOCSIS do wykonania DOCSIS-TFTP i pobrania aktualnego firmware NETII na ich serwerze TFTP w sieci CMTS, czy może jednak na tym serwerze są tylko pliki konfiguracyjne dla modemu (typu ilość kanałów, modulacja...)?

Temat nie jest związany z LEDE, więc nie umieściłem go w sekcji "Oprogramowanie", jest natomiast związany z modyfikacją oprogramowania. Jeśli Administroator uważa, że post powinien znaleźć się w innej sekcji, proszę o przeniesienie.

Z góry dziękuję wszystkim za pomoc.

PS: Testów dokonuję na własnym TC7200, kupionym na OLX. NIE MODYFIKUJĘ ROUTERU NETII. Po udanej modyfikacji, zajmę się spoofowaniem (lub może permamentą zmianą) adersu MAC modemu, abym mógł podłączyć własny TC7200.

1. Tam jest bootloader który wczytuje właściwy system z nandu.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Aha, to nie ma już problemu z bootloader'em. Programator do SPI mam. Mam tylko jedno dodatkowe pytanie: Po czym to poznałeś? Nie zauważyłem nic, co by mówiło o obecności na tej kości BL.

PS: Czy zna ktoś jakieś forum do sieci kablowych? Może to złe forum na zadawanie tego typu pytań.

Bo tak zwykle jest smile Zresztą zobacz:

Masz w spi zapisane informacje o tym jak układ flash wygląda.

Chciałem odświeżyć trochę temat, bo widzę że po jednym dniu brak odpowiedzi. Jakoś mało osób do działu "Inne" zagląda hmm. Czy ktoś jest może zorientowany w działaniu tego modelu i/lub w działaniu sieci CMTS/DOCSIS-IP w NETII? Nie pójdę dalej, dopóki nie dostanę binarki z oprogramowaniem, które jest na TFTP NETII.

Chciałbym przedstawić informacje, które do tej pory udało mi się zdobyć.

1. Udało mi się znaleźć repo z GitHub'a: https://github.com/jclehner/bcm2-utils, które obsługuje zgranie NAND'a przez serial do pliku. Po szybkiej inspekcji kodu (do bcm2dump nie było go dużo) wykorzystuje "Read memory" dla danego adresu, interpretuje stdin i przeskakuje do kolejnego adresu. Niestety, nadal przeszkodą jest brak możliwości odczytania niczego, co jest zapisane w adresach wcześniejszych niż 0x80000000.

2. Skontaktowałem się z osobą obeznaną w temacie modyfikacji oprogramowania. Poradziła mi abym wykonał następujące czynności: Spróbować dodać do bootargs kernela ("Linux Boot Args" w logu z 1. postu) init=/bin/sh albo init=/bin/bash. Niestety, raczej możliwości edytowania tych argumentów nie mam. Bootloader obsługuje tylko bardzo małą liczbę komend, dostępnych przez menu:

Osoba ta podała mi również link do strony z informacją na temat źródeł oprogramowania do TC7200: "https://www.phoronix.com/scan.php?page= … Opens-TC72". Poleciła mi (w miarę możliwości) skompilowania initramfs, przez który możnaby było uzyskać dostęp do flashy bez ograniczeń.

Witam wszystkich ponownie, nie zajmowałem się modemem ze względu na brak czasu. Od kilku dni walczę z kompilacją źródeł. Oprogramowanie jest dość stare, więc niektóre funkcje, np. defined(@sth) w Perlu nie działały i musiałem troszeczkę zmienić kod (nie dużo bo np. z defined(@sth) do @sth). Poza tym musiałem doinstalować bison, flex i gawk, o których nie ma ani słowa w README. Niestety nie udało mi się skompilować poprawnie kernela i initramu. Cały czas coś się kompilatorowi nie podobało. W końcu, pod wpływem frustracji, zdając sobie sprawę z krytycznych skutków, jakie mogło to za sobą nieść, wywołałem make z parametrem -i. Ostatecznie kompilacja dobiegła końca i zostałem z tym: https://www.dropbox.com/s/gs3yyolr2riwj7n/vmlinux?dl=1. Po wgraniu tego przez TFTP do RAM i odpaleniu, obraz się nie zbootował (co mnie nie dziwi, skompilował się z błędami krytycznymi). Chyba coś jest nie tak z sumą kontrolną nagłówka. Czy ktoś jest wstanie mi pomóc z kompilacją, albo powiedzieć mi co jeszcze muszę poprawić? Cały czas próbuję, ale bez skutków. Log z bootowania obrazu:

Nawiązując do poprzedniego posta: przepraszam, zapomniałem wkleić najważniejsze - logi z kompilacji... To są logi z kompilowania bez ignorowania błędów. Jest to trochę długie (na tyle, że zabrakło miejsca w buforze i część ucięło tongue), więc zostawiłem tylko końcowe części (tam, gdzie są błędy). Jutro prześlę pełne logi z kompilacji bez i z parametrem -i, bo jak wspomniałem buforu zabrakło, a poza tym log jest za duży i będę musiał uploadować gdzie indziej.

Ktoś może podpowiedzieć jak poprawić błąd? Z tego co rozumiem, problemem dla kompilatora jest ponowna definicja funkcji hashtable_iterator_key. To raczej nie jest błąd związany z różnicą kompilatorów z 2009 i 2018... (a może...?). Niech się wypowiedzą znawcy C i gcc.

@MrCiek4wski
Czy udało Ci się osiągnąć coś więcej w zakresie modyfikacji/otwarcia tego środowiska?

Pozdrawiam
Marcin

Może być jak piszesz - najlepiej posadź sobie w wirtualce jakiegoś ubuntu z tamtych lat i po prostu zainstaluj w tej wirtualce zestaw oprogramowania dla kompilacji openwrt, jako podstawa dalszych działań.
Druga kwestia, że jak posiadasz źródła, można znaleźć pośrednio w plikach informację o wymaganych wersjach różnych programów w systemie dla kompilacji lub w ogóle jakie konkretnie biblioteki/programy są potrzebne aby kompilacja się powiodła.
