gcc accepts
__asm__ ( "" : : : "%cc");
but cc is not a real register and clang does not like it.
networking/tls_pstm_montgomery_reduce.c:385:4: error: unknown register name '%cc' in asm
| INNERMUL;
| ^
The % syntax nominally goes before a register, in this case cc,
like "memory" isn't a true register it's just a way of specifying that
the condition code registers for the target are clobbered

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

If you don't care about everything being logged at LOG_ERR level
then when FEATURE_SYSLOG_INFO is disabled Busybox actually gets smaller:

Today for gzipped content httpd is using a header with name
Transfer-Length. However I can't find a header with that name in the

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).
