[System C (kugui)] Suspension of Certain Debugging Functions Due to Security Measures
Starting at 9:00 AM on May 19, on System C (kugui),
in order to apply a temporary fix for a Linux kernel vulnerability,
until a new patched kernel becomes available,
you will be unable to run debuggers such as gdb
or the strace command, which utilize the Linux kernel’s ptrace system call.
We apologize for any inconvenience this may cause
and appreciate your understanding.
