Stepping through with a debugger, it looks like the marshaled `value` from
the field has the expected value:
```
(gdb) f
#0 LogFilterIP::is_match (this=0x30c7ec0, lad=0x7ff4a6b6af40) at
LogFilter.cc:840
840 zret = m_map.contains(reinterpret_cast<IpAddr &>(value));
(gdb) l
835 if (m_field && lad) {
836 LogFieldIpStorage value;
837 m_field->marshal(lad, reinterpret_cast<char *>(&value));
838 // This is bad, we abuse the fact that the initial layout of
LogFieldIpStorage and IpAddr
839 // are identical. We should look at converting the log stuff to
use IpAddr directly.
840 zret = m_map.contains(reinterpret_cast<IpAddr &>(value));
841 }
842
843 return zret;
844 }
(gdb) p value
$11 = {
_ip = {
_family = 2
},
_ip4 = {
<LogFieldIp> = {
_family = 2
},
members of LogFieldIp4:
_addr = 16777343 // <--- This corresponds to 127.0.0.1
},
_ip6 = {
<LogFieldIp> = {
_family = 2
},
members of LogFieldIp6:
_addr = {
__in6_u = {
__u6_addr8 =
"\177\000\000\001@\000\000\000\000\000\000\000@\000\000",
__u6_addr16 = {127, 256, 64, 0, 0, 0, 64, 0},
__u6_addr32 = {16777343, 64, 0, 64}
}
}
}
}
```
But the m_map of the local LogFilterIP is empty:
```
(gdb) p m_map
$12 = {
static RAW_IP4_MIN_ADDR = 0,
static IP4_MIN_ADDR = {
_family = 2,
_addr = {
_ip4 = 0,
_ip6 = {
__in6_u = {
__u6_addr8 = '\000' <repeats 15 times>,
__u6_addr16 = {0, 0, 0, 0, 0, 0, 0, 0},
__u6_addr32 = {0, 0, 0, 0}
}
},
_byte = '\000' <repeats 15 times>,
_u32 = {0, 0, 0, 0},
_u64 = {0, 0}
},
static INVALID = {
_family = 0,
_addr = {
_ip4 = 0,
_ip6 = {
__in6_u = {
__u6_addr8 = '\000' <repeats 15 times>,
__u6_addr16 = {0, 0, 0, 0, 0, 0, 0, 0},
__u6_addr32 = {0, 0, 0, 0}
}
},
_byte = '\000' <repeats 15 times>,
_u32 = {0, 0, 0, 0},
_u64 = {0, 0}
},
static INVALID = <same as static member of an already seen type>
}
},
static RAW_IP4_MAX_ADDR = 4294967295,
static IP4_MAX_ADDR = <same as static member of an already seen type>,
static RAW_IP6_MIN_ADDR = <same as static member of an already seen type>,
static IP6_MIN_ADDR = <same as static member of an already seen type>,
static RAW_IP6_MAX_ADDR = <same as static member of an already seen type>,
static IP6_MAX_ADDR = <same as static member of an already seen type>,
_m4 = 0x30c7f60,
_m6 = 0x0
}
```
