Variables
SshKeyMat	ssh_keys [MAX_SSH_CONNS]
	Pool of session key material, one entry per MAX_SSH_CONNS.
SshDhState	ssh_dh [MAX_SSH_CONNS]
	Pool of ephemeral DH state, one entry per MAX_SSH_CONNS.

Detailed Description

BSS definitions for SSH session key and DH state pools.

Declared extern in ssh_keymat.h; defined here as separate linker symbols so that a linear overflow from ssh_pkt[] (in ssh_packet.cpp) cannot reach ssh_keys[] or ssh_dh[] in a single stride. See ssh_keymat.h for the full security rationale.

Definition in file ssh_keymat.cpp.
