2020-12-15udhcp: bind to device even for ucast packetsMichal Kazior
There are cases where binding to source IP and destination IP is insufficient to guarantee sane xmit netdev. One case where this can fail is when route-matching netdev carrier is down (cable unplugged, wifi disconnected), or the netdev is admin down. Then all the IP based bindings (bind() + connect()) will seemingly succeed but the actual packet can go out through a default gw path. Depending on the network this happens on it can create issues or false alarms. It can also leak some subnet info across networks that shouldn't be routed. As such better be safe than sorry and bind to a netdev to be sure it's used for xmit. function old new delta udhcp_send_kernel_packet 293 336 +43 send_packet 182 188 +6 bcast_or_ucast 37 43 +6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 55/0) Total: 55 bytes Signed-off-by: Michal Kazior <michal@plume.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2020-08-15httpd: Support caching via ETag headerSergey Ponomarev
If server responds with ETag then next time client can resend it via If-None-Match header. Then httpd will check if file wasn't modified and if not return 304 Not Modified status code. The ETag value is constructed from file's last modification date in unix epoch and it's size: "hex(last_mod)-hex(file_size)" e.g. "5e132e20-417" (with quotes). That means that it's not completely reliable as hash functions but fair enough. The same form of ETag is used by Nginx so load balancing of static content is safe. function old new delta handle_incoming_and_exit 2135 2201 +66 http_response 88 96 +8 send_headers 676 683 +7 parse_conf 1362 1365 +3 http_response_type 22 24 +2 send_file_and_exit 847 841 -6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 5/1 up/down: 86/-6) Total: 80 bytes Signed-off-by: Sergey Ponomarev <stokito@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2020-08-15httpd: Don't add Last-Modified header to responseSergey Ponomarev
The Last-Modified header is used for caching. The client (browser) will send back the received date to server via If-Modified-Since request header. But both headers MUST be an RFC 1123 formatted string. And the formatting consumes resources on request parsing and response generation. Instead we can use ETag header. This simplifies logic and the only downside is that in JavaScript the document.lastModified will return null.
