This is a known issue that should be fixed in a future version of Cumulus RMP.
|In traditional bridge mode, clagd syncs MAC addresses in the wrong VLAN when the peerlink is tagged and the bond is native||
When a traditional mode bridge is configured and the peerlink is tagged but the clagd bonds are native VLANs, clagd appears to try and sync the MAC addresses learned using the VLAN tag from the peerlink.
This causes the MAC address not to be synced correctly on the peer.
This is a known issue that should be fixed in a future release of Cumulus RMP.
|Default routes learned via DHCP are moved to the management VRF even if they are not in the management VRF||
Until this issue is resolved, do not use DHCP with the front panel (switch) ports.
|An interface cannot have both inet and inet6 DHCP configurations||
If you configure an interface so it can to obtain both IPv4 and IPv6 IP addresses via DHCP,
In the following example configuration,
auto swp1 iface swp1 inet dhcp link-speed 10000 link-duplex full link-autoneg off auto swp1 iface swp1 inet6 dhcp
|hsflowd - packet samples missing and default nflog group not set since 3.x||
An issue occurrs where only counter samples are generated when
cumulus@switch:~$ cat /proc/bcm/knet/sample_groups Sample NFLOG group (unit 0): rx=1 tx=0
|CVE-2016-7042: /proc/keys stack corruption kernel security bug||
A Linux kernel vulnerability was found that when the GNU Compiler Collection (gcc) stack protector is enabled, it uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading the
This issue is fixed in Cumulus RMP 3.2.0.
|TACACS+ client users can't login with eth0 in management VRF||An issue occurred when process context was not causing the socket to the server to be bound to the management VRF. This resulted in the TACACS+ client user failing to login with eth0. The issue has now been resolved.|
|Memory leak caused by duplicate MAC address entries||A memory leak was seen when users manually configured a VLAN-aware bridge along with a controller/vtepd provisioned traditional bridge. This was caused by the same MAC address on different VLANs being seen as duplicates in the bridge MAC entries list. This memory leak has now been corrected.|
