usr.bin/ssh : sshbuf.c
Log message:
Extend sshbuf validation
Multiple sshbuf structs can be linked through a parent/child relationship.
Make sure that a single sshbuf cannot be its own parent. If this would ever
happen, it would result in reference counting issues.
This is a cheap way of testing this with very little overhead. It does not
detect A->B->A linkages though for performance reason and the fact that it
takes a programming error for this to occur anyway.
