md5/sha1sum: Honor the -b flag in the output

2026-01-18T02:09:52+00:00

The output of md5sum/sha1sum contains a character to indicate what mode was used to read the file - '*' for binary, and ' ' for text or where binary is insignificant. This flag character makes a difference for the ffmpeg testsuite. This testsuite contains a number of reference files (e.g. [1]), containing the expected md5sum output for those files, which is checked verbatim. By making busybox's md5sum honor this flag in the output, ffmpeg's testsuite can run successfully on top of busybox. The flag is only partially implemented; in coreutils md5sum, a later "-t" option overrides an earlier "-b" option. Here, just check if a "-b" option was specified or not. Neither flag affects how the files actually are read.

md5/shaXsum: accept uppercase hex strings

The coreutils versions of md5sum and the like accept uppercase hex strings from checksum files specified with the '-c' option. Use a case-insensitive comparison so BusyBox does the same. Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko

XXXsum: handle binary sums with " " in the path

If a line specifies a binary checksum whose path contains two adjacent spaces, when checking digests with -c the two spaces will be used as the separator between the digest and the pathname instead of " *", as shown: $ echo foo > "/tmp/two spaces" $ md5sum -b "/tmp/two spaces" # This is GNU md5sum d3b07384d113edec49eaa6238ad5ff00 */tmp/two spaces $ md5sum -b "/tmp/two spaces" | ./busybox md5sum -c md5sum: can't open 'spaces': No such file or directory spaces: FAILED md5sum: WARNING: 1 of 1 computed checksums did NOT match function old new delta md5_sha1_sum_main 503 496 -7 Signed-off-by: Emanuele Giacomelli Signed-off-by: Denys Vlasenko

libbb: reduce the overhead of single parameter bb_error_msg() calls

2019-07-02T09:35:03+00:00

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.
