Package: general Severity: important Tags: l10n Dear Maintainer,
While doing unrelated storage testing for our VMware integrated product, we purposefully recreated a storage outage by removing the iSCSI initiators from the backing array hosting the vmdk disk images for the virtual machine. Upon removal of uplinks to storage, the VM goes into a R/O file system state after 5-10 minutes. When storage initiators are brought back up and the LUNs are rescanned, the VM begins to rapidly request DHCP leases from an ISC DHCP server. This DoS's the server in a way due to the number of DHCPDECLINE errors, and the interface attempts to take and discard IP's in a rapid fashion. This only seems to appear on this distribution, and I can't replicate the behavior on Debian 9 or in a desktop environment. -- System Information: Debian Release: 10.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-5-amd64 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
