[servconf.c servconf.h sshd.c sshd_config.5 sandbox-rlimit.c] [sandbox-systrace.c sandbox.h configure.ac Makefile.in] introduce sandboxing of the pre-auth privsep child using systrace(4). This introduces a new "UsePrivilegeSeparation=sandbox" option for sshd_config that applies mandatory restrictions on the syscalls the privsep child can perform. This prevents a compromised privsep child from being used to attack other hosts (by opening sockets and proxying) or probing local kernel attack surface. The sandbox is implemented using systrace(4) in unsupervised "fast-path" mode, where a list of permitted syscalls is supplied. Any syscall not on the list results in SIGKILL being sent to the privsep child. Note that this requires a kernel with the new SYSTR_POLICY_KILL option. UsePrivilegeSeparation=sandbox will become the default in the future so please start testing it now. feedback dtucker@; ok markus@

[auth-options.c auth-options.h auth.c auth.h auth2-pubkey.c] [key.c servconf.c servconf.h sshd.8 sshd_config.5] add some optional indirection to matching of principal names listed in certificates. Currently, a certificate must include the a user's name to be accepted for authentication. This change adds the ability to specify a list of certificate principal names that are acceptable. When authenticating using a CA trusted through ~/.ssh/authorized_keys, this adds a new principals="name1[,name2,...]" key option. For CAs listed through sshd_config's TrustedCAKeys option, a new config option "AuthorizedPrincipalsFile" specifies a per-user file containing the list of acceptable names. If either option is absent, the current behaviour of requiring the username to appear in principals continues to apply. These options are useful for role accounts, disjoint account namespaces and "user@realm"-style naming policies in certificates. feedback and ok markus@
