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.

2016-09-07sendmail: make it possible to pause after connection helper is startedDenys Vlasenko
If a non-starttls helper is in use, initial 220 response is processed by us, not by helper. Some servers consider us to be a spammer if we don't wait for it. It is not in protocol, but it is a real-life problem. The workaround in this patch is a magic envvar, $SMTP_ANTISPAM_DELAY: ... -H 'PROG ARGS' Run connection helper. Examples: openssl s_client -quiet -tls1 -starttls smtp -connect smtp.gmail.com:25 openssl s_client -quiet -tls1 -connect smtp.gmail.com:465 $SMTP_ANTISPAM_DELAY: seconds to wait after helper connect ...

If we get an address we cannot parse properly, we currently just strip the unknown characters and still try to send it.

Instead, skip sending to an address we cannot fully understand and print the characters what we have scanned so far. Leading and trailing whitespace is allowed and silently stripped.

2012-04-28sendmail: use host rather than NIS domain name for HELORon Yorston
According to RFC 5321 the argument to HELO "contains the fully-qualified domain name of the SMTP client" or its IP address if no FQDN is available. BusyBox sendmail uses the NIS domain name instead which, in many cases, is likely to be the default "(none)". [vda: yes, I checked my machine and its uts.domainname was indeed "(none)"] Using the host name is more likely to satisfy the intent of the RFC while allowing the otherwise unused safe_getdomainname function to be removed.
