+ o Minor bugfixes (Linux seccomp2 sandbox):
+ - The getpid() system call is now permitted under the Linux seccomp2
+ sandbox, to avoid crashing with versions of OpenSSL (and other
+ libraries) that attempt to learn the process's PID by using the
+ syscall rather than the VDSO code. Fixes bug 21943; bugfix on
+ 0.2.5.1-alpha.
