[PATCH 1/3] Move zero IP checking into clones_add/clones_remove.
The callers of clones_add and clone_remove were directly accessing the client's IP address. Move this checking into the two functions, to make it easier to change later. --- src/clones.c | 6 ++++++ src/s_misc.c | 6 ++---- src/s_user.c | 6 ++---- 3 files changed, 10 insertions(+), 8 deletions(-) diff --git a/src/clones.c b/src/clones.c index 1c63914..f4d6fc2 100644 --- a/src/clones.c +++ b/src/clones.c @@ -274,6 +274,9 @@ clones_add(aClient *cptr) CloneEnt *ceip; CloneEnt *ce24; + if (cptr->ip.s_addr == 0) + return; + get_clones(cptr, &ceip, &ce24, 1); cptr->clone.prev = NULL; @@ -301,6 +304,9 @@ clones_remove(aClient *cptr) CloneEnt *ceip; CloneEnt *ce24; + if (cptr->ip.s_addr == 0) + return; + get_clones(cptr, &ceip, &ce24, 0); if (cptr->clone.next) diff --git a/src/s_misc.c b/src/s_misc.c index 39108c5..4114fd5 100644 --- a/src/s_misc.c +++ b/src/s_misc.c @@ -363,8 +363,7 @@ exit_one_client_in_split(aClient *cptr, aClient *dead, char *reason) if (cptr->user->alias) cptr->user->alias->client = NULL; - if (cptr->ip.s_addr) - clones_remove(cptr); + clones_remove(cptr); #ifdef RWHO_PROBABILITY probability_remove(cptr); @@ -763,8 +762,7 @@ exit_one_client(aClient *cptr, aClient *sptr, aClient *from, char *comment) while ((lp = sptr->user->channel)) remove_user_from_channel(sptr, lp->value.chptr); - if (sptr->ip.s_addr) - clones_remove(sptr); + clones_remove(sptr); #ifdef RWHO_PROBABILITY probability_remove(sptr); diff --git a/src/s_user.c b/src/s_user.c index c9d89d0..3d3cf34 100644 --- a/src/s_user.c +++ b/src/s_user.c @@ -1003,16 +1003,14 @@ register_user(aClient *cptr, aClient *sptr, char *nick, char *username) } /* do this late because of oper masking */ - if (sptr->ip.s_addr) - clones_add(sptr); + clones_add(sptr); } else if (IsServer(cptr)) { aClient *acptr; /* do this early because exit_client() calls clones_remove() */ - if (sptr->ip.s_addr) - clones_add(sptr); + clones_add(sptr); if ((acptr = find_server(user->server, NULL)) && acptr->from != sptr->from) -- 1.7.2.3
This function allows us to avoid using touching the raw IP address for an client when all we really want is the string version. Also increase HOSTIPLEN to 45 characters, which will allow an IPv6 address to fit. Based on the function from mamikk's old patch. --- include/h.h | 1 + include/struct.h | 2 +- src/m_server.c | 4 ++-- src/s_bsd.c | 4 ++-- src/s_misc.c | 10 +++++----- src/s_user.c | 8 ++++---- src/support.c | 9 +++++++++ src/userban.c | 4 ++-- 8 files changed, 26 insertions(+), 16 deletions(-) diff --git a/include/h.h b/include/h.h index 467fadb..137fcba 100644 --- a/include/h.h +++ b/include/h.h @@ -180,6 +180,7 @@ extern char *getreply(int); extern char *strerror(int); extern int dgets(int, char *, int); extern char *inetntoa(char *); +extern char *cipntoa(aClient *); extern int dbufalloc, dbufblocks, debuglevel, errno; extern int highest_fd, debuglevel, portnum, debugtty, maxusersperchannel; diff --git a/include/struct.h b/include/struct.h index 307826c..523b61d 100644 --- a/include/struct.h +++ b/include/struct.h @@ -112,7 +112,7 @@ typedef struct SAliasInfo AliasInfo; /* comply with RFC1123 */ -#define HOSTIPLEN 15 /* Length of dotted quad form of IP */ +#define HOSTIPLEN 45 /* Length of an IPv4 or IPv6 address */ #define NICKLEN 30 diff --git a/src/m_server.c b/src/m_server.c index 76dfab3..f4ce52e 100644 --- a/src/m_server.c +++ b/src/m_server.c @@ -54,7 +54,7 @@ static void sendnick_TS(aClient *cptr, aClient *acptr) acptr->name, acptr->hopcount + 1, acptr->tsinfo, ubuf, acptr->user->username, acptr->user->host, acptr->user->server, acptr->user->servicestamp, - inetntoa((char *)&acptr->ip), acptr->info); + cipntoa(acptr), acptr->info); } else { @@ -456,7 +456,7 @@ m_server_estab(aClient *cptr) cptr->serv->up = me.name; cptr->serv->aconn = aconn; - throttle_remove(inetntoa((char *)&cptr->ip)); + throttle_remove(cipntoa(cptr)); #ifdef HAVE_ENCRYPTION_ON if(!CanDoDKEY(cptr) || !WantDKEY(cptr)) diff --git a/src/s_bsd.c b/src/s_bsd.c index 7b021dc..10243ef 100644 --- a/src/s_bsd.c +++ b/src/s_bsd.c @@ -608,7 +608,7 @@ int check_client(aClient *cptr) int i; Debug((DEBUG_DNS, "ch_cl: check access for %s[%s]", - cptr->name, inetntoa((char *) &cptr->ip))); + cptr->name, cipntoa(cptr))); if (check_init(cptr, sockname)) return -2; @@ -716,7 +716,7 @@ int check_server_init(aClient * cptr) { sendto_realops_lev(ADMIN_LEV, "Server IP# Mismatch: %s != %s[%08lx]", - inetntoa((char *) &cptr->ip), hp->h_name, + cipntoa(cptr), hp->h_name, *((unsigned long *) hp->h_addr)); hp = NULL; } diff --git a/src/s_misc.c b/src/s_misc.c index 4114fd5..04adf46 100644 --- a/src/s_misc.c +++ b/src/s_misc.c @@ -194,7 +194,7 @@ get_client_name(aClient *sptr, int showip) if (IsServer(sptr)) { if (showip == TRUE) - s += ircsprintf(s, "[%s]", inetntoa((char *)&sptr->ip)); + s += ircsprintf(s, "[%s]", cipntoa(sptr)); else if (showip != HIDEME) s += ircsprintf(s, "[%s]", sptr->sockhost); } @@ -202,7 +202,7 @@ get_client_name(aClient *sptr, int showip) { if (showip == TRUE) s += ircsprintf(s, "!%s@%s", sptr->user->username, - inetntoa((char *)&sptr->ip)); + cipntoa(sptr)); else if (showip != HIDEME) s += ircsprintf(s, "!%s@%s", sptr->user->username, sptr->user->host); @@ -222,7 +222,7 @@ get_client_name(aClient *sptr, int showip) if (showip == TRUE) s += ircsprintf(s, "]%s@%s)", sptr->username, - inetntoa((char *)&sptr->ip)); + cipntoa(sptr)); else s += ircsprintf(s, "]%s@%s)", sptr->username, sptr->sockhost); @@ -850,14 +850,14 @@ exit_banned_client(aClient *cptr, int loc, char type, char *banmsg, int fast) sendto_one(cptr, "NOTICE %s :*** Reason: %s", target, reason); sendto_one(cptr, "NOTICE %s :*** Connection info: %s [%s]", target, get_client_name(cptr, FALSE), - inetntoa((char *)&cptr->ip.s_addr)); + cipntoa(cptr)); sendto_one(cptr, "NOTICE %s :*** Ban contact: %s", target, loc ?
