| #383 | fixed | Konami code detection takes quadratic time in number of keystrokes | andersk | |
| Description |
scripts-pony/scripts/templates/master.mak has a very inefficient Konami code detection easter egg that appends all keystrokes to a JavaScript? array. It should be rewritten to use the obvious 11-state Knuth–Morris–Pratt FSM. This now also affects XVM, who copied this code. |

| #387 | worksforme | OpenAFS getcwd() sometimes returns ENOENT | andersk | |
| Description |
Every few hours, a server gets stuck in a state where certain users receive ENOENT from getcwd(), resulting in errors like shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory Sometimes the problem goes away on its own, but usually the server needs to be rebooted. I attempted to debug this with upstream on 2013-06-11 and 2013-06-16. Using crash, I found that we’re ending up with two dentries referring to the same directory inode, which is bad. We’re all confused. |

| #389 | fixed | Enable HTTPS perfect forward secrecy | andersk | |
| Description |
This is complicated by the requirement to keep SSLSessionTicketKeyFile out of persistent storage, rotate it frequently, and synchronize it across servers. It would also be nice to remember the last N old keys so that each rotation doesn’t force every user to establish a new SSL session. We’ll probably need to do some Apache development. https://www.imperialviolet.org/2013/06/27/botchingpfs.html https://blog.twitter.com/2013/forward-secrecy-at-twitter-0 |
