2019-04-30Optionally re-introduce bb_info_msg()James Byrne
Between Busybox 1.24.2 and 1.25.0 the bb_info_msg() function was eliminated and calls to it changed to be bb_error_msg(). The downside of this is that daemons now log all messages to syslog at the LOG_ERR level which makes it hard to filter errors from informational messages. This change optionally re-introduces bb_info_msg(), controlled by a new option FEATURE_SYSLOG_INFO, restores all the calls to bb_info_msg() that were removed (only in applets that set logmode to LOGMODE_SYSLOG or LOGMODE_BOTH), and also changes informational messages in ifplugd and ntpd. The code size change of this is as follows (using 'defconfig' on x86_64 with gcc 7.3.0-27ubuntu1~18.04) function old new delta bb_info_msg - 182 +182 bb_vinfo_msg - 27 +27 static.log7 194 198 +4 log8 190 191 +1 log5 190 191 +1 crondlog 45 - -45 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 3/0 up/down: 215/-45) Total: 170 bytes If you don't care about everything being logged at LOG_ERR level then when FEATURE_SYSLOG_INFO is disabled Busybox actually gets smaller: function old new delta static.log7 194 200 +6 log8 190 193 +3 log5 190 193 +3 syslog_level 1 - -1 bb_verror_msg 583 581 -2 crondlog 45 - -45 ------------------------------------------------------------------------------ (add/remove: 0/2 grow/shrink: 3/1 up/down: 12/-48) Total: -36 bytes Signed-off-by: James Byrne <james.byrne@origamienergy.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-04-16httpd: do not percent-decode URI if proxyingDenys Vlasenko
The proxying is documented as follows: P:/url:[http://]hostname[:port]/new/path Howeverm urlcopy is not a true copy anymore when it is fdprint'ed to proxy_fd, this is because percent_decode_in_place() is called after the copy is created. This breaks reverse proxying all URIs containing percent encoded spaces, e.g. - because a decoded URI will be printed out to proxy_fd instead of the original. The fix keeps the logic in place to canonicalize the uri first, before reverse proxying (one could argue that the uri should be proxied completely unaltered, except for the prefix rewrite). function old new delta handle_incoming_and_exit 2752 2792 +40 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
