2020-08-15httpd: Don't add Date header to responseSergey Ponomarev
RFC 2616 sec. 14.18 says that server MUST send Date header. But in fact the header make sense only for Cache-Control and can be omitted. In the same time the Date eats power, CPU and network resources which are critical for embedded systems.

2020-08-15httpd: Update to HTTP/1.1Sergey Ponomarev
HTTP v1.1 was released in 1999 year and it's time to update BB HTTPD. Browsers may behave badly with HTTP/1.0 E.g. Chrome does not send the If-None-Match header with ETag. Signed-off-by: Sergey Ponomarev <stokito@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2020-08-13build system: drop PLATFORM_LINUXRon Yorston
PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount. Remove all references to PLATFORM_LINUX and compile match_fstype.c if mount or umount is enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Duplicate options are currently overridden (only the last option is kept). This leads to unexpected behavior when using long options.

2020-06-09httpd: allow '-h' to work when daemonized with NOMMU enabledRon Yorston
Commit d1b75e184 (httpd: permit non-default home directory with NOMMU enabled) only works when used with the '-f' (foreground) option. When '-f' isn't specified and NOMMU is enabled bb_daemonize_or_rexec() is called to daemonize the server. Since the server process has been re-execed the previous patch results in the xchdir() not being called. Fix this by resetting the re_execed variable in this case.

2020-04-30httpd: permit non-default home directory with NOMMU enabledRon Yorston
When BusyBox is compiled with NOMMU enabled running httpd with the '-h' option fails even if the specified directory exists: $ ls -d www www $ busybox httpd -fvvvp 8080 -h www ... ... try to access http://localhost:8080/www ... httpd: can't change directory to 'www': No such file or directory The parent process executes xchdir("www"). When a connection is accepted it's handled by re-executing httpd in inetd mode. The child process inherits the current directory "www" and tries to change directory again to "www", which fails. Omit the call to xchdir() when httpd is re-executed. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-10-30ntpd: decrease MIN_FREQHOLD by 2, increase "penalty" for largish offset x2Denys Vlasenko
> 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>

2019-10-27nslookup: handle replies without RRsJo-Philipp Wich
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.

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>
