"bootfile_name_alt" dhcp userdata is encoded as option 254 since it is not currently used. When both "bootfile_name" and "bootfile_name_alt" are provided by the CMS, "bootfile_name" will be used for option 67 if the dhcp request contains etherboot option (175), otherwise "bootfile_name_alt" will be used. "bootfile_name" and "bootfile_name_alt" are placed just after offer_ip in userdata buffer. Tested-by: Lucas Alvares Gomes Martins Signed-off-by: Lorenzo Bianconi --- Changes since v2: - encode "bootfile_name" and "bootfile_name_alt" are placed just after offer_ip in userdata buffer in order to avoid loops in pinctrl_handle_put_dhcp_opts() Changes since v1: - encode bootfile_name_alt option as 254 in order to not increase userdata buffer size --- controller/pinctrl.c | 30 ++++++++++++ lib/actions.c | 33 ++++++++++--- lib/ovn-l7.h | 7 +++ northd/ovn-northd.c | 1 + ovn-nb.xml | 10 ++++ tests/ovn.at | 110 ++++++++++++++++++++++++++++++------------- tests/test-ovn.c | 1 + 7 files changed, 154 insertions(+), 38 deletions(-) diff --git a/controller/pinctrl.c b/controller/pinctrl.c index d85ba504d..6f5499f0b 100644 --- a/controller/pinctrl.c +++ b/controller/pinctrl.c @@ -1868,6 +1868,7 @@ pinctrl_handle_put_dhcp_opts( } in_dhcp_ptr += sizeof magic_cookie;
