Regarding the wiki, it's a useful summary. However, #561203 (minifail
bug) is not a "Futex wait failure". We may have futex bugs, but I'm
not
aware of a testcase. The minifail bug is a "Threads and fork" problem
arising from cache corruption. Mainly, copy_user_page is broken when
copying memory shared by more than one process. There are also issues
in PTE/TLB management on SMP systems. Probably, the vfork/execve bug
is caused by the same problem.
Many thanks for the feedback. The reason why I initially put the
minifail bug under "Futex wait failure" was because I found it
discussed under such a thread ;-)
I've merged this section under "Threads & fork", and have quoted your
summary at the top of the section.
