[PATCH v6 0/9] ssh signing: verify key lifetime

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



changes since v5:
 - moved the fixes to existing test to the first two commits and merged
   those fixing new tests into the corresponding commit

changes since v4:
 - removed unneccessary io redir in merge-msg tests
 - added grep for merged tag to gpgssh merge-msg tests

changes since v3:
 - improve readability of prereq setup code by using heredoc and some
   variables

changes since v2:
 - fix swich/case indentation
 - BUG() on unknown payload types
 - improve test prereq by actually validating ssh-keygen functionality

changes since v1:
 - struct signature_check is now used to input payload data into
   check_function
 - payload metadata parsing is completely internal to check_signature.
   the caller only need to set the payload type in the sigc struct
 - small nits and readability fixes
 - removed payload_signer parameter. since we now use the struct we can
   extend
   this later.

  ssh signing: make git log verify key lifetime
  ssh signing: make verify-tag consider key lifetime
  ssh signing: make fmt-merge-msg consider key lifetime
  ssh signing: verify ssh-keygen in test prereq
