* adduser: remove preconfigured GECOS full name fieldAchill Gilgenast2026-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | Pre-configuring "Linux User" as Full Name is confusing a lot of users downstream.[1] For example, in geary e-mails were sent out as "Linux User"[2] and I also saw a couple of git commits with this name. This name does not bring any more improvements than just leaving this field empty, and let applications most likely fallback to the username. Alternative would be to set the field to `&` (Capitalized username, according to passwd(5)) or that we just set the GECOS field downstream.

* md5/sha1sum: Honor the -b flag in the outputMartin Storsjö2026-01-182-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* cmp: stop skipping bytes if EOF is reachedGiorgi Tchankvetadze2026-01-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if a skip value is larger than the file size, cmp will continue to loop and call getc() until the skip count is satisfied, even though EOF has been reached. For large skip values (e.g., 1 billion), this results in significant CPU waste and execution time (e.g., 11 seconds on a modern CPU). This patch checks for EOF inside the skip loop and breaks early.
