Subject: Ignore SIGPIPE in keyd
X-Git-Url: https://git.sommitrealweird.co.uk/onak.git/commitdiff_plain/f9917d386685c7f641d493dbc78eb3eb41fb24bd?ds=inline;hp=0fac914c0876bf3cf78c12ea0b9b44880fbdffa4

Ignore SIGPIPE in keyd

  catchsignals() normally catches SIGPIPE and sets the cleanup flag,
  as per the other signals it catches. This is fine for the HKP CGI,
  but not appropriate for keyd (as it's probably because the client
  has exited without doing appropriate cleanup). Ignore it; we'll
  deal with the error when we try to read/write to the socket.
