2 daysash: fix help builtin and tab completion of builtinsRon Yorston1-0/+8
Commit 56143ea63 (ash: code shrink: eliminate pstrcmp1()) changed the layout of struct builtincmd so the name member points to the start of the name, not the flag in the first element of the string. This broke the help builtin and tab completion of builtins. Remove the unnecessary '+ 1' in ash_command_name() and helpcmd(). This patch has been submitted upstream.

7 daysvolume_id: volume_id_get_buffer with small FSesAlyssa Ross via busybox1-3/+2
I was working with some very small ext4 filesystems, used for overlaying on immutable VM/container images. If it's only desired to overlay a single config file, these filesystems can be very small indeed, and so ran afoul of this length check. Since 4fc5ec56f ("device matching against UUIDs: do not try floppies") (from 2009), floppy drives are skipped before this function is even called. Reading from an unused loop device returns 0, so it should be fine to reduce the minimum length.

10 daysutil-linux: add minimal uuidgen implementationOsama Abdelkader via busybox2-3/+60
Add a simple uuidgen utility that generates RFC 4122 compliant UUIDs (version 4, random). Uses the existing generate_uuid() function from libbb and volume_id_set_uuid() for formatting. Implementation suggested by Ulli. Features: - Generates standard format UUIDs: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx - RFC 4122 version 4 compliant - Minimal implementation (~1.1 kb) - NOFORK applet for efficiency - Uses existing volume_id infrastructure for UUID formatting function old new delta uuidgen_main - 71 +71 applet_names 2862 2870 +8 .rodata 107010 107016 +6 applet_main 1648 1652 +4 applet_suid 103 104 +1 applet_install_loc 206 207 +1 applet_flags 103 104 +1 packed_usage 35952 35941 -11 ------------------------------------------------------------------------------ (add/remove: 2/0 grow/shrink: 6/1 up/down: 92/-11) Total: 81 bytes Signed-off-by: Osama Abdelkader <osama.abdelkader@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
10 dayslibbb: fix regression where 'which' output duplicate slashesRon Yorston1-0/+8
If an element of $PATH had a trailing slash 'which' displayed two slashes when an executable was found in that directory. This is a regression caused by upstream commit 49d9e06fb (libbb: modify find_executable() to not temporarily write to PATH). Prior to this commit find_executable() used concat_path_file() to build the path of the executable. This avoids including duplicate slashes in its output. The new code didn't. Add a test in find_executable() to detect the problem. It still fails if there are multiple trailing slashes. Don't do that. Adds 48 bytes.
