I obtained a bachelor’s degree in computer science from Lanzhou University in 2023, under the guidance of Associate Professor Xin Liu (刘新).

I ventured into the field of security halfway through. Moreover, I am also intrigued by system research, especially the kernel and related areas.

The experience gained from my recent Linux kernel trimming project sparked my curiosity about Linux kernel.

My research interest includes kernel, cyber security, as well as performance analysis and tuning.

Safer Seccomp: Dead Syscalls Elimination

Yuan Tan, Zhangjin Wu, Xiao Liu

  • Contributed kernel patches to Linux. Discovered excitement and passion around kernels.
  • Utilized compiler directives to establish reference relationships for all orphaned sections.
  • The excessive use of ‘KEEP()’ in the Linux kernel can be eliminated using the above method.
  • Made the elimination of unused system calls possible through the construction of references between segments.
  • Reduced the size of the kernel image by 7%.
  • Reduced the attack surface that prevents attackers from exploiting trimmed syscalls.
  • The early version has received positive feedback from the maintainer.
