Bug ID: 271308
Summary: [FIB] File exists while adding IPv4
Product: Base System
Version: 13.2-STABLE
Hardware: Any
OS: Any
Status: New

Hello,
I have jail with vlans and bird with full feed.
After upgrade from 13.1/Stable to 13.2/Stable I can't add subnet do interface
when it exists in the routing table, e.g.:
route -nv get 10.8.3.1
RTA_DST: inet 10.8.3.1; RTA_IFP: link ; RTM_GET: Report Metrics: len 224, pid:
0, seq 1, errno 0, flags:<UP,GATEWAY,HOST,STATIC>
locks: inits:
sockaddrs: <DST,IFP>
10.8.3.1 link#0
route to: 10.8.3.1
destination: 10.8.3.0
mask: 255.255.255.0
gateway: xx.xx.92.217
fib: 0
interface: vlan4007
flags: <UP,GATEWAY,DONE,PROTO1>
recvpipe sendpipe ssthresh rtt,msec mtu weight expire
0 0 0 0 1500 1 0
locks: inits:
sockaddrs: <DST,GATEWAY,NETMASK,IFP,IFA>
10.8.3.0 xx.xx.92.217 255.255.255.0 vlan4007:0.7.43.6c.f3.d0 xx.xx.92.218
# birdc show route for 10.8.3.1
BIRD 2.13 ready.
Table master4:
10.8.3.0/24 unicast [CORE_OSPF 09:31:03.342] * E1 (150/31)
[xx.xx.58.18]
via xx.xx.92.217 on vlan4007
# ifconfig vlan40 10.8.3.1/24 alias
ifconfig: ioctl (SIOCAIFADDR): File exists
Problem is with the same size len of prefixes. If I try to add more specific
# ifconfig vlan40 10.8.3.1/25 alias
not errors, IPv4 has been added
