From interpreter.c


case CON_GET_NAME: /* wait for input of name */
if (d->character == NULL) {
CREATE(d->character, struct char_data, 1);
clear_char(d->character);
CREATE(d->character->player_specials, struct player_special_data, 1);

new_mobile_data(d->character);

GET_HOST(d->character) = strdup(d->host);
d->character->desc = d;
}
if (!*arg)
STATE(d) = CON_CLOSE;
else {
char buf[MAX_INPUT_LENGTH], tmp_name[MAX_INPUT_LENGTH];

if ((_parse_name(arg, tmp_name)) || strlen(tmp_name) < 2 ||
strlen(tmp_name) > MAX_NAME_LENGTH || !valid_name(tmp_name) ||
fill_word(strcpy(buf, tmp_name)) || reserved_word(buf)) { /* strcpy: OK (mutual MAX_INPUT_LENGTH) */
write_to_output(d, "Invalid name, please try another.\r\nName: ");
return;
}


The game will crash when a character with exactly MAX_NAME_LENGTH is created.

Nice finding.

created character aaaaaaaaaaaaaaaaaaaa (20 chars)
and, it crash on class choosing 'M' magical user.

you can try:
structs.h
struct recent_player
replace char name[MAX_NAME_LENGTH]
to char name[MAX_NAME_LENGTH+1]
seems to fix it, but i'll let thomas analyse the code in depth :)

Weird, I just did the same thing on my copy of the mud in exactly the same way and it didn't crash. I successfully went through character generation and logged into the game. 21 characters or more resulted in "Invalid name." Perhaps it's your implementation of strlen()? Maybe strnlen() might be the better option?

DESCRIPTION
The strlen() function computes the length of the string s.

The strnlen() function computes the length of the string s, up to maxlen
characters. The strnlen() function will never attempt to address more
than maxlen characters, making it suitable for use with character arrays
that are not guaranteed to be NUL-terminated.

RETURN VALUES
The strlen() function returns the number of characters that precede the
terminating NUL character.

The strnlen() function returns the number of characters that precede the
terminating NUL or maxlen, whichever is smaller.

By what name do you wish to be known? duckduckduckduckduck
Did I get that right, Duckduckduckduckduck (Y/N)? y
New character.
Give me a password for Duckduckduckduckduck:
Please retype password:
What is your sex (M/F)? m

Select a class:
[C]leric
[T]hief
[W]arrior
[M]agic-user

Class: m


But. like i said:
Code:
/* Add player to recent player list */ bool AddRecentPlayer(char *chname, char *chhost, bool newplr, bool cpyplr) { struct recent_player *this; time_t ct; int max_vnum; if (!chname || !*chname) // dropped connection with no name given return FALSE; ct = time(0); /* Grab the current time */ this = create_recent(); if (!this) return FALSE; this->time = ct; this->new_player = newplr; this->copyover_player = cpyplr; strcpy(this->host, chhost); strcpy(this->name, chname); max_vnum = get_max_recent(); this->vnum = max_vnum; /* Possibly should be +1 ? */ return TRUE; }

Changing:
Code:
/** structure for list of recent players (see 'recent' command) */ struct recent_player { int vnum; /* The ID number for this instance */ char name[MAX_NAME_LENGTH]; /* The char name of the player */ bool new_player; /* Is this a new player? */ bool copyover_player; /* Is this a player that was on during the last copyover? */ time_t time; /* login time */ char host[HOST_LENGTH+1]; /* Host IP address */ struct recent_player *next; /* Pointer to the next instance */ };

Changing: char name[MAX_NAME_LENGTH]
by: char name[MAX_NAME_LENGTH+1]
fix the issue.

Weird, I just did the same thing on my copy of the mud in exactly the same way and it didn't crash. I successfully went through character generation and logged into the game. 21 characters or more resulted in "Invalid name." Perhaps it's your implementation of strlen()? Maybe strnlen() might be the better option?


Well, if i understand. It's a buffer overflow detected by "LibC" ? That, send SIGABORT to the program?
Maybe, your version of the library is diffrent, and doesn't detect it... and, since it's a small overflow it's doesn't affect the program execution on your system maybe?
