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>

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>

2019-07-02libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne
Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.
