Russell Senior	1c461df70a	udhcpc: ignore zero-length DHCP options Discovered that the DHCP server on a TrendNet router (unknown model) provides a zero-length option 12 (Host Name) in the DHCP ACK message. This has the effect of causing udhcpc to drop the rest of the options, including option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server), most importantly leaving the OpenWrt device with no default gateway. The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that option 12 has a minimum length of 1 octet. It is perhaps not a cosmic coincidence that I found this behavior on Pi Day. This patch allows zero length options without bailing out, by simply skipping them. function old new delta udhcp_scan_options 183 172 -11 Signed-off-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2021-03-16 11:40:19 +01:00

Michal Kazior	b817699e6c	udhcp: bind to device even for ucast packets 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>	2020-12-15 21:44:21 +01:00

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).

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.

Denys Vlasenko	ea096d6c13	ntpd: decrease MIN_FREQHOLD by 2, increase "penalty" for largish offset x2 > 2018-07-25: > ntpd: increase MIN_FREQHOLD by 3 > This means we'll start correcting frequency ~5 minutes after start, > not ~3.5 ones. > With previous settings I still often see largish ~0.7s initial offsets > only about 1/2 corrected before frequency correction kicks in, > resulting in ~200ppm "correction" which is then slowly undone. Review of real-world results of the above shows that with small initial offsets, freq correction can be allowed to kick in sooner, whereas with large (~0.8s) offsets, we still start freq correction a bit too soon. Let's rebalance this a bit. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2019-10-30 12:18:07 +01:00

Jo-Philipp Wich	8c3b520d4f	nslookup: handle replies without RRs Under some circumstances, a DNS reply might contain no resource records, e.g. when a valid domain is queried that does not have records of the requested type. Example with nslookup from BIND dnsutils: $ nslookup -q=SRV example.org Server: 10.11.12.13 Address: 10.11.12.13#53 Non-authoritative answer: *** Can't find example.org: No answer Currently the busybox nslookup applet simply prints nothing after the "Non-authoritative answer:" line in the same situation. This change modifies nslookup to either print "Parse error" or "No answer" diagnostics, depending on the parse_reply() return value. function old new delta send_queries 1676 1711 +35 Signed-off-by: Jo-Philipp Wich <jo@mein.io> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2019-10-27 17:02:08 +01:00
