In practice everyone numbers their channels sequentially, so this has never been a problem. ok markus@

Explicitly pass "struct ssh" to all channels functions. Replace use of the legacy packet APIs in channels.c. Rework sshd_config PermitOpen handling: previously the configuration parser would call directly into the channels layer. After the refactor this is not possible, as the channels structures are allocated at connection time and aren't available when the configuration is parsed. The server config parser now tracks PermitOpen itself and explicitly configures the channels code later. ok markus@

CVSROOT:/cvs Module name:src Changes by: d...@cvs.openbsd.org2017/09/11 20:56:54 Modified files: sys/arch/amd64/amd64: vm_machdep.c Log message: add a guard page on the end of each threads kernel stack. this protects the process control block. it also makes the kernel fault hard when the guard page gets hit by the stack, allowing debugging of the problem set of function calls at the time the problem occurs. without this, a big stack can overwrite the pcb, which makes the thread generate a fault when it is switched back onto a cpu, which is way too late. discussed with guenther@ ok deraadt@
