[Libvirt-cim] [PATCH 4/4] FilterEntry: Accept protocol id string values

From: "Eduardo Lima (Etrunko)" <eblima(a)br.ibm.com&gt; The HdrProtocolID8021 property expects an unsigned int value, while libvirt network filters specification allows the corresponding value for this property (protocolid) to be written as a string (ipv4, ipv6, arp, rarp). The corresponding values for the protocolid strings can be found in: http://www.iana.org/assignments/ethernet-numbers Signed-off-by: Eduardo Lima (Etrunko) <eblima(a)br.ibm.com&gt; --- src/Virt_FilterEntry.c | 26 ++++++++++++++++++++++++-- 1 files changed, 24 insertions(+), 2 deletions(-) diff --git a/src/Virt_FilterEntry.c b/src/Virt_FilterEntry.c index 2ff354a..126615b 100644 --- a/src/Virt_FilterEntry.c +++ b/src/Virt_FilterEntry.c @@ -219,6 +219,24 @@ static int convert_action(const char *s) return action; } +static unsigned long convert_protocol_id(const char *s) +{ + enum {NONE = 0, IPV4 = 2048, ARP = 2054, RARP = 32821, IPV6 = 34525} id = NONE; + + if (s != NULL) { + if (STREQC(s, "ipv4")) + id = IPV4; + else if (STREQC(s, "arp")) + id = ARP; + else if (STREQC(s, "rarp")) + id = RARP; + else if (STREQC(s, "ipv6")) + id = IPV6; + } + + return id; +} + static void convert_mac_rule_to_instance( struct acl_rule *rule, CMPIInstance *inst, @@ -265,8 +283,12 @@ static void convert_mac_rule_to_instance( (CMPIValue *)&array, CMPI_uint8A); if (rule->var.mac.protocol_id != NULL) { - unsigned long n = strtoul(rule->var.mac.protocol_id, - NULL, 16); + unsigned long n = convert_protocol_id(rule->var.mac.protocol_id); + + /* Unknown protocolid string.
