+Subject: [PATCH] Update Linux Seccomp syscall restrictions to EPERM
+ posix_spawn/vfork
+
+Glibc's system() function switched to using posix_spawn, which uses
+CLONE_VFORK. Pepperflash includes a sandbox debugging check which
+relies on us EPERM-ing process creation like this, rather than crashing
+the process with SIGSYS.
+
+So whitelist clone() calls, like posix_spawn, that include the flags
+CLONE_VFORK and CLONE_VM.
+
