            Bug ID: 1674
           Summary: ebtables causing packet loss
           Product: ebtables
           Version: unspecified
          Hardware: x86_64
                OS: All
            Status: NEW
          Severity: critical
          Priority: P5

Hi,

Package version : ebtables 1.8.4 (nf_tables)

Kernel version : 4.18.0-425.13.1.el8_7.x86_64

OS version : AlmaLinux release 8.7 (Stone Smilodon)



I am using AlmaLinux 8 on a dedicated server and hosting VPSes using KVM.
Applying ebtables rules on those VPSes is causing packet loss issue.

Bridge chain: v1001, entries: 1, policy: DROP -p IPv4 -s 00:xx:xx:52:69:ac
--ip-src 192.168.122.204 -j ACCEPT

Bridge chain: v1001IPV6, entries: 0, policy: DROP

Bridge chain: v1001ARPIN, entries: 2, policy: ACCEPT -p ARP --arp-ip-src
192.168.122.204 --arp-mac-src 00:xx:xx:52:69:ac -j ACCEPT -p ARP -j DROP

There are around 100 VPSes hosted. Applying/loading rules for all those VPSes
all at once would cause issues ?

Where else can I check for logs ?
