Changes made between OpenBSD 5.5 and 5.6

• Fixed ssl(8) to avoid allocating and then leaking a fresh fragment structure when a zero-length fragment is received (CVE-2014-3507).
• Fixed ssl(8): made sure the output buffer is always NUL terminated if buf_len was initially greater than zero; reject OIDs that are too long, too short, or not in proper base-127 (CVE-2014-3508).
• Corrected ssl(8) test (reversed during merge of fix for CVE-2014-3509).
• Fixed ssl(8) DTLS handshake message size checks (CVE-2014-3506).
• Stopped httpd(8) trying to output FCGI_STDERR into error.log if there is no data.
• Try to parse "Status: $code" in the first response from the httpd(8) fcgi daemon, use that code as HTTP response code (fallback to 200). Possible fix for redirects in cvsweb.
• Fixed ssl(8) TLS downgrade (CVE-2014-3511).
• Fixed DTLS anonymous EC(DH) denial of service in ssl(8) (CVE-2014-3510).
• Made httpd(8) correctly report "internal server error" if the very first fcgi STDOUT record has length 0.
• Changed httpd.conf(5) grammar to remove a shift/reduce conflict. "listen on $ip port 443 ssl" turns into "listen on $ip ssl port 443".
• Added support for NOTE_EOF (for kqueue(2) EVFILT_READ filters) on NFS files.
• Limit the body size in client requests (eg. POST data) to 1M by default in httpd.conf(5); added a configuration option to change the limit.
• Prevented X(7) server crash on zaurus (and possibly other architectures) where there is no pci(4).
• Provided httpd.conf(5) configuration options that allow the SSL certificate, key and ciphers to be specified for each server.
• Clear the httpd(8) public key when it is no longer needed.
• Configured the default ssl(8) ciphers as HIGH:!aNULL in httpd(8).
• Restored previous ssl(8) behaviour that allows a PEM block to be fed through the base64 decoder.
• Corrected some dma cleanup error paths in qe(4/vax).
• POST support added to httpd(8).
• Added CONTENT_TYPE environment variables (without the HTTP_prefix) to httpd(8), for use with cgi scripts .
• Fixed bug in server_write that broke httpd(8) keep-alive support.
• httpd(8) now adjusts read/write watermarks according to the TCP send buffer. Fixes sending of large files.
• Load the httpd(8) ssl(8) public/private keys in the parent process, then provide them to the privsep process via imsg. Allows keys to be moved out of chroot(8).
• Added ssl(8) support for loading the public/private key from memory, rather than directly from file.
• If a driver (eg umct(4)) opens an interrupt pipe without callback function, made sure the correct transfer is aborted.
• Added httpd.conf(5) options for max requests per connection and timeout limit.
• Brought back httpd.conf(5) TCP/IP configuration options.
• Limited the number of Keep-Alive requests per httpd(8) connection to 100.
• Improved httpd(8) logging to allow per-server/location log files; log files can now be owned by root.
• Added httpd.conf(5) option to specify the chroot(8) directory.
• Enabled httpd(8) in rc.d(8) for wider testing.
• Temporarily moved default location of the httpd(8) SSL/TLS server key and certificate from /var/www/ to /var/www/conf/.
• Added "HTTPS = on" CGI variable to httpd(8).
• Redirect httpd(8) to https:// if SSL/TLS is enabled.
• Added TLS/SSL support to httpd(8), based on the recent ssl(8) commits.
• Changed httpd.conf(5) grammar from "log [style]" to "log style [style]".
• Provided an ssl(8) function that returns a server connection context.

• Extended httpd(8) to dynamically pass HTTP request headers as protocol-specific HTTP_* CGI meta-variables.
• Add ral(4) to GENERIC and RAMDISK on macppc.
• Fixed sys/dev/usb/ehci.c r1.162 to stop returning initialised memory on error in ehci_alloc_sqtd().
• Fixed sys/dev/ic/bwi.c r1.106. Prevents packet loss.
• Split httpd(8) fastcgi socket path and document root options; added the SCRIPT_FILENAME CGI param with a prepended root. Fixes php-fpm that expects SCRIPT_FILENAME.
• Added missing httpd(8) log call for fastcgi requests.
• Added another httpd.conf(5) log mode "connection" for a relayd(8)-style log entry after each connection.
• httpd(8) now prefers getnameinfo() with NI_NUMERICHOST over inet_ntop (to include IPv6 scope ID).

• Rewrote httpd(8) fcgi_add_param and hand over a lot more http headers etc. to the cgi script.
• Correctly parse fastcgi records if httpd(8) doesn't get the whole record in one bufferevent_read().
• Allow softraid(4) rebuilds to work correctly when the volume metadata has a different data offset to that currently in use.
• Unbroke aac(4), by re-adding uvm_extern.h for ptoa().
• httpd(8) now only writes the HTTP header for the first fastcgi chunk.
• httpd(8) fastcgi improvements: submit QUERY_STRING, if it exists; use a proper function to create an HTTP header; use server_file_error() to detect EOF and fastcgi stream errors; disable keep-alive/persist until there is a reliable way to get the content length.
• Use exact on-disk inode size with ext2 filesystems.
• Properly evaluate rc.d(8) values only after running _rc_quirks(), because these can modify flags.
• In rc.d(8) debug mode, properly sort and drop duplicate entries to make output less confusing.
• Allow httpd.conf(5) to specify a non-default fastcgi socket.
• Renamed httpd(8) "docroot" variable to "path" (as it will be used for either files or the fastcgi socket).

• Fixed strtonum(3) range, to unbreak "-pass fd:0" in ssl(8).
• Cleaned up portable arc4random(3) fork detection code; let it take advantage of systems with healthy getentropy(2).

• m4(1) will now annotate regexp error messages with the source string.
