File Add-support-for-configuring-Infiniband-GUIDs.patch of Package iproute2.7171
From: Eli Cohen <eli@mellanox.com> Date: Thu, 7 Jul 2016 16:09:03 -0500 Subject: Add support for configuring Infiniband GUIDs Patch-mainline: v4.7.0 Git-commit: d91fb3f4c7e4dba806541bdc90b1fb60a3581541 References: bsc#1081176 Add two NLA's that allow configuration of Infiniband node or port GUIDs by referencing the IPoIB net device set over the physical function. The format to be used is as follows: ip link set dev ib0 vf 0 node_guid 00:02:c9:03:00:21:6e:70 ip link set dev ib0 vf 0 port_guid 00:02:c9:03:00:21:6e:78 Signed-off-by: Eli Cohen <eli@mellanox.com> Acked-by: Michal Kubecek <mkubecek@suse.cz> --- include/utils.h | 1 + ip/iplink.c | 20 ++++++++++++++++++++ lib/utils.c | 35 +++++++++++++++++++++++++++++++++++ man/man8/ip-link.8.in | 12 +++++++++++- 4 files changed, 67 insertions(+), 1 deletion(-) diff --git a/include/utils.h b/include/utils.h index cc821e80b257..91a06a2080ed 100644 --- a/include/utils.h +++ b/include/utils.h @@ -213,5 +213,6 @@ int do_each_netns(int (*func)(char *nsname, void *arg), void *arg, bool show_label); char *int_to_str(int val, char *buf); +int get_guid(__u64 *guid, const char *arg); #endif /* __UTILS_H__ */ diff --git a/ip/iplink.c b/ip/iplink.c index 31ceb7e3520a..36b01bac5cc8 100644 --- a/ip/iplink.c +++ b/ip/iplink.c @@ -381,6 +381,26 @@ static int iplink_parse_vf(int vf, int *argcp, char ***argvp, invarg("Invalid \"state\" value\n", *argv); ivl.vf = vf; addattr_l(&req->n, sizeof(*req), IFLA_VF_LINK_STATE, &ivl, sizeof(ivl)); + } else if (matches(*argv, "node_guid") == 0) { + struct ifla_vf_guid ivg; + + NEXT_ARG(); + ivg.vf = vf; + if (get_guid(&ivg.guid, *argv)) { + invarg("Invalid GUID format\n", *argv); + return -1; + } + addattr_l(&req->n, sizeof(*req), IFLA_VF_IB_NODE_GUID, &ivg, sizeof(ivg)); + } else if (matches(*argv, "port_guid") == 0) { + struct ifla_vf_guid ivg; + + NEXT_ARG(); + ivg.vf = vf; + if (get_guid(&ivg.guid, *argv)) { + invarg("Invalid GUID format\n", *argv); + return -1; + } + addattr_l(&req->n, sizeof(*req), IFLA_VF_IB_PORT_GUID, &ivg, sizeof(ivg)); } else { /* rewind arg */ PREV_ARG(); diff --git a/lib/utils.c b/lib/utils.c index 8b0b5b51d584..25990beb6931 100644 --- a/lib/utils.c +++ b/lib/utils.c @@ -1060,3 +1060,38 @@ char *int_to_str(int val, char *buf) sprintf(buf, "%d", val); return buf; } + +int get_guid(__u64 *guid, const char *arg) +{ + unsigned long int tmp; + char *endptr; + int i; + +#define GUID_STR_LEN 23 + /* Verify strict format: format string must be + * xx:xx:xx:xx:xx:xx:xx:xx where xx can be an arbitrary + * hex digit + */ + + if (strlen(arg) != GUID_STR_LEN) + return -1; + + /* make sure columns are in place */ + for (i = 0; i < 7; i++) + if (arg[2 + i * 3] != ':') + return -1; + + *guid = 0; + for (i = 0; i < 8; i++) { + tmp = strtoul(arg + i * 3, &endptr, 16); + if (endptr != arg + i * 3 + 2) + return -1; + + if (tmp > 255) + return -1; + + *guid |= tmp << (56 - 8 * i); + } + + return 0; +} diff --git a/man/man8/ip-link.8.in b/man/man8/ip-link.8.in index cc1d144ba084..fbbca4f08034 100644 --- a/man/man8/ip-link.8.in +++ b/man/man8/ip-link.8.in @@ -158,7 +158,11 @@ ip-link \- network device configuration .br .RB "[ " state " { " auto " | " enable " | " disable " } ]" .br -.RB "[ " trust " { " on " | " off " } ] ]" +.RB "[ " trust " { " on " | " off " } ]" +.br +.RB "[ " node_guid " eui64 ]" +.br +.RB "[ " port_guid " eui64 ] ]" .br .in -9 .RB "[ " master @@ -1038,6 +1042,12 @@ sent by the VF. .BI trust " on|off" - trust the specified VF user.
