* [PATCH] net: sched: Add support for packet bursting. @ 2021-06-25 12:03 Niclas Hedam 2021-06-25 20:54 ` kernel test robot ` (2 more replies) 0 siblings, 3 replies; 7+ messages in thread From: Niclas Hedam @ 2021-06-25 12:03 UTC (permalink / raw) To: stephen; +Cc: netdev Hello, This patch implements packet bursting in the NetEm scheduler. This allows system administrators to hold back outgoing packets and release them at a multiple of a time quantum. This feature can be used to prevent timing attacks caused by network latency. I'm currently publishing a paper on this, which is currently not publicly available, but the idea is based on Predictive Black-Box Mitigation of Timing Channels (https://dl.acm.org/doi/pdf/10.1145/1866307.1866341).
