From aac372f4f5b617a579dafeab31fb486a5d69d65d Mon Sep 17 00:00:00 2001 From: hasso Date: Thu, 1 Sep 2005 17:52:33 +0000 Subject: * isis_adjacency.c, isis_lsp.c, isisd.c: Replace XMALLOC && memset with XCALLOC. * isis_lsp.c (lsp_build_pseudo): Fix adding ES neighbour. * isis_tlv.c: More compact free_tlvs() function. * isis_lsp.c (lsp_build_nonpseudo) : Try to fix one more regression introduced by stream cleanup. Seek enp to the right place before starting to fill stream with TLVs. --- isisd/isis_lsp.c | 48 ++++++++++++++++++++++-------------------------- 1 file changed, 22 insertions(+), 26 deletions(-) (limited to 'isisd/isis_lsp.c') diff --git a/isisd/isis_lsp.c b/isisd/isis_lsp.c index 0860b150..52896c4e 100644 --- a/isisd/isis_lsp.c +++ b/isisd/isis_lsp.c @@ -437,9 +437,7 @@ lsp_new_from_stream_ptr (struct stream *stream, { struct isis_lsp *lsp; - lsp = XMALLOC (MTYPE_ISIS_LSP, sizeof (struct isis_lsp)); - memset (lsp, 0, sizeof (struct isis_lsp)); - + lsp = XCALLOC (MTYPE_ISIS_LSP, sizeof (struct isis_lsp)); lsp_update_data (lsp, stream, area); if (lsp0 == NULL) @@ -467,14 +465,13 @@ lsp_new (u_char * lsp_id, u_int16_t rem_lifetime, u_int32_t seq_num, { struct isis_lsp *lsp; - lsp = XMALLOC (MTYPE_ISIS_LSP, sizeof (struct isis_lsp)); + lsp = XCALLOC (MTYPE_ISIS_LSP, sizeof (struct isis_lsp)); if (!lsp) { /* FIXME: set lspdbol bit */ zlog_warn ("lsp_new(): out of memory"); return NULL; } - memset (lsp, 0, sizeof (struct isis_lsp)); #ifdef LSP_MEMORY_PREASSIGN lsp->pdu = stream_new (1514); /*Should be minimal mtu? yup... */ #else @@ -924,7 +921,7 @@ lsppdu_realloc (struct isis_lsp * lsp, int memorytype, int size) #else /* otherwise we have to move all pointers */ u_char *newpdu; newpdu = stream_new (ntohs (lsp->lsp_header->pdu_len) + size); - stream_put (newpdu, STREAM_DATA(lsp->pdu), ntohs (lsp->lsp_header->pdu_len); + stream_put (newpdu, STREAM_DATA(lsp->pdu), ntohs (lsp->lsp_header->pdu_len)); XFREE (memorytype, lsp->pdu); lsp->pdu = newpdu; lsp->isis_header = (struct isis_fixed_hdr *) STREAM_DATA (lsp->pdu); @@ -1004,8 +1001,7 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) { if (lsp->tlv_data.is_neighs == NULL) lsp->tlv_data.is_neighs = list_new (); - is_neigh = XMALLOC (MTYPE_ISIS_TLV, sizeof (struct is_neigh)); - memset (is_neigh, 0, sizeof (struct is_neigh)); + is_neigh = XCALLOC (MTYPE_ISIS_TLV, sizeof (struct is_neigh)); memcpy (&is_neigh->neigh_id, area->topology_baseis, ISIS_SYS_ID_LEN); /* connected to the first */ is_neigh->neigh_id[ISIS_SYS_ID_LEN - 1] = (0x01); @@ -1041,7 +1037,7 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) for (ALL_LIST_ELEMENTS (circuit->ip_addrs, ipnode, ipnnode, ipv4)) { ipreach = - XMALLOC (MTYPE_ISIS_TLV, sizeof (struct ipv4_reachability)); + XCALLOC (MTYPE_ISIS_TLV, sizeof (struct ipv4_reachability)); ipreach->metrics = circuit->metrics[level - 1]; ipreach->prefix = ipv4->prefix; masklen2ip (ipv4->prefixlen, &ipreach->mask); @@ -1064,8 +1060,7 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) ipnnode, ipv6)) { ip6reach = - XMALLOC (MTYPE_ISIS_TLV, sizeof (struct ipv6_reachability)); - memset (ip6reach, 0, sizeof (struct ipv6_reachability)); + XCALLOC (MTYPE_ISIS_TLV, sizeof (struct ipv6_reachability)); ip6reach->metric = htonl (circuit->metrics[level - 1].metric_default); ip6reach->control_info = 0; @@ -1087,8 +1082,7 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) lsp->tlv_data.is_neighs = list_new (); lsp->tlv_data.is_neighs->del = free_tlv; } - is_neigh = XMALLOC (MTYPE_ISIS_TLV, sizeof (struct is_neigh)); - memset (is_neigh, 0, sizeof (struct is_neigh)); + is_neigh = XCALLOC (MTYPE_ISIS_TLV, sizeof (struct is_neigh)); if (level == 1) memcpy (&is_neigh->neigh_id, circuit->u.bc.l1_desig_is, ISIS_SYS_ID_LEN + 1); @@ -1108,8 +1102,7 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) lsp->tlv_data.is_neighs = list_new (); lsp->tlv_data.is_neighs->del = free_tlv; } - is_neigh = XMALLOC (MTYPE_ISIS_TLV, sizeof (struct is_neigh)); - memset (is_neigh, 0, sizeof (struct is_neigh)); + is_neigh = XCALLOC (MTYPE_ISIS_TLV, sizeof (struct is_neigh)); memcpy (&is_neigh->neigh_id, nei->sysid, ISIS_SYS_ID_LEN); is_neigh->metrics = circuit->metrics[level - 1]; listnode_add (lsp->tlv_data.is_neighs, is_neigh); @@ -1275,7 +1268,7 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) #endif /* HAVE_IPV6 */ ) { - lsp->tlv_data.nlpids = XMALLOC (MTYPE_ISIS_TLV, sizeof (struct nlpids)); + lsp->tlv_data.nlpids = XCALLOC (MTYPE_ISIS_TLV, sizeof (struct nlpids)); lsp->tlv_data.nlpids->count = 0; if (area->ip_circuits > 0) { @@ -1305,6 +1298,13 @@ lsp_build_nonpseudo (struct isis_lsp *lsp, struct isis_area *area) /* * Building the zero lsp */ + + /* Reset stream endp.
