From 51d4ef832c1e58150325630e25c442866e5a6cf5 Mon Sep 17 00:00:00 2001 From: Josh Bailey Date: Wed, 21 Mar 2012 17:13:39 -0700 Subject: zebra: include hardware addr in if up/down messages Change interface up/down notification messages to also include the hardware address of the interface. The format of these messages is now identical to the interface add message -- move the serialization code to common functions. * lib/zclient.c: Modify zebra_interface_if_set_value() to also parse the hardware address. Invoke it from zebra_interface_add_read() and and zebra_interface_state_read(). * zebra/zserv.c: Add zserv_encode_interface(). Invoke it from zserv_interface_add(), zserv_interface_delete() and zserv_interface_update(). --- lib/zclient.c | 36 +++++++--------------------- zebra/zserv.c | 76 ++++++++++++++++++++++------------------------------------- 2 files changed, 37 insertions(+), 75 deletions(-) diff --git a/lib/zclient.c b/lib/zclient.c index 52a3627d..85aa737e 100644 --- a/lib/zclient.c +++ b/lib/zclient.c @@ -611,24 +611,8 @@ zebra_interface_add_read (struct stream *s) /* Lookup/create interface by name. */ ifp = if_get_by_name_len (ifname_tmp, strnlen(ifname_tmp, INTERFACE_NAMSIZ)); - /* Read interface's index. */ - ifp->ifindex = stream_getl (s); + zebra_interface_if_set_value (s, ifp); - /* Read interface's value. */ - ifp->status = stream_getc (s); - ifp->flags = stream_getq (s); - ifp->metric = stream_getl (s); - ifp->mtu = stream_getl (s); - ifp->mtu6 = stream_getl (s); - ifp->bandwidth = stream_getl (s); -#ifdef HAVE_STRUCT_SOCKADDR_DL - stream_get (&ifp->sdl, s, sizeof (ifp->sdl)); -#else - ifp->hw_addr_len = stream_getl (s); - if (ifp->hw_addr_len) - stream_get (ifp->hw_addr, s, ifp->hw_addr_len); -#endif /* HAVE_STRUCT_SOCKADDR_DL */ - return ifp; } @@ -656,16 +640,7 @@ zebra_interface_state_read (struct stream *s) if (! ifp) return NULL; - /* Read interface's index. */ - ifp->ifindex = stream_getl (s); - - /* Read interface's value. */ - ifp->status = stream_getc (s); - ifp->flags = stream_getq (s); - ifp->metric = stream_getl (s); - ifp->mtu = stream_getl (s); - ifp->mtu6 = stream_getl (s); - ifp->bandwidth = stream_getl (s); + zebra_interface_if_set_value (s, ifp); return ifp; } @@ -715,6 +690,13 @@ zebra_interface_if_set_value (struct stream *s, struct interface *ifp) ifp->mtu = stream_getl (s); ifp->mtu6 = stream_getl (s); ifp->bandwidth = stream_getl (s); +#ifdef HAVE_STRUCT_SOCKADDR_DL + stream_get (&ifp->sdl, s, sizeof (ifp->sdl)); +#else + ifp->hw_addr_len = stream_getl (s); + if (ifp->hw_addr_len) + stream_get (ifp->hw_addr, s, ifp->hw_addr_len); +#endif /* HAVE_STRUCT_SOCKADDR_DL */ } static int diff --git a/zebra/zserv.c b/zebra/zserv.c index 2330135a..23a5c4e8 100644 --- a/zebra/zserv.c +++ b/zebra/zserv.c @@ -131,6 +131,30 @@ zserv_create_header (struct stream *s, uint16_t cmd) stream_putw (s, cmd); } +static void +zserv_encode_interface (struct stream *s, struct interface *ifp) +{ + /* Interface information. */ + stream_put (s, ifp->name, INTERFACE_NAMSIZ); + stream_putl (s, ifp->ifindex); + stream_putc (s, ifp->status); + stream_putq (s, ifp->flags); + stream_putl (s, ifp->metric); + stream_putl (s, ifp->mtu); + stream_putl (s, ifp->mtu6); + stream_putl (s, ifp->bandwidth); +#ifdef HAVE_STRUCT_SOCKADDR_DL + stream_put (s, &ifp->sdl, sizeof (ifp->sdl)); +#else + stream_putl (s, ifp->hw_addr_len); + if (ifp->hw_addr_len) + stream_put (s, ifp->hw_addr, ifp->hw_addr_len); +#endif /* HAVE_STRUCT_SOCKADDR_DL */ + + /* Write packet size. */ + stream_putw_at (s, 0, stream_get_endp (s)); +} + /* Interface is added.
