In the Linux kernel, the following vulnerability has been resolved:
af_unix: Set gc_in_progress to true in unix_gc().
Igor Ushakov reported that unix_gc() could run with gc_in_progress being false if the work is scheduled while running:
Thread 1 Thread 2 Thread 3
unix_schedule_gc() unix_schedule_gc()
`- if (!gc_in_progress) `- if (!gc_in_progress)
|- gc_in_progress = true |

`- gc_in_progress = false
unix_peek_fpl() relies on gc_in_progress not to confuse GC by MSG_PEEK.
Let's set gc_in_progress to true in unix_gc().
