Comment:

 Hello Alec,

 thanks for all the code. Looks like a great start, and I think it will be
 very
 useful in the future!

 Now for some logistics: are you planning to work more on this? If yes,
 when
 should we expect updates here? These days we are actively working on
 implementing prop224, and the `ESTABLISH_INTRO` cell is one of our next
 steps, so
 I'd like to see if your schedule is compatible with our plans.

 As a first step, I took a look at your code and did a bit of review. You
 can
 find my comments and changes in my branch `prop224-alec` at:
     https://gitweb.torproject.org/user/asn/tor.git/log/?h=prop224-alec

 Note that there have been some recent prop224 torspec changes (like the
 keylen
 size) that impact the `ESTABLISH_INTRO` cell slightly.

 Here are some future steps on this area:

 - Address the XXXs I added to the code.

 - Write unit tests.

 - Move prop224 functions like `rend_mid_establish_intro_p224()` to their
 own file.
   Maybe call new file `hs_intro_point.c` or something. Also maybe rename
 that function to
   `rend_mid_handle_establish_intro_prop224()`?

 - Write function-level documentation.

 - Run `make check-spaces` and fix the various whitespace/style issues.

 Let me know if you plan to work on these, and if you have an ETA on
 delivery,
 so that we can count you in our implementation roadmap :)

 Cheers!
