2021-03-09tar: fix base-256 output.Elliott Hughes
A tar file created by toybox tar with values large enough to need base-256 rather than ASCII octal caused a tar reader to crash, and caused GNU tar to complain. I note from the docs at https://github.com/libarchive/libarchive/blob/master/libarchive/tar.5#L326 that they imply that only the top *bit* should be set to indicate this format, not the whole top byte, to give a 95-bit or 63-bit field. But I don't think we can hit that in practice? Bug: http://issuetracker.google.com/181683612

2021-02-23dd: simplify signal handling and fix status output.Elliott Hughes
Other dd implementations always show the status on exit, whether success or failure. Fix that by using xsigatexit() (and clarify the comment for that function a little, since it didn't previously address the "at exit" part of its behavior at all). This also fixes SIGUSR1 behavior so that we show the status immediately rather than on the next trip round the read/write loop. Tested with `dd of=/dev/full`, sending SIGUSR1 twice from another shell (to see the status immediately each time, without exiting), then hitting ^C (to see the status and then exiting), then restarting dd and hitting enter (to see a write error followed by the status before exiting).

2021-02-22stat: fix macOS build and behavior.Elliott Hughes
My patch to fix df behavior on macOS broke the stat build on macOS. First off, we had %s and %S the wrong way round compared to coreutils, though since Linux always seems to use the same value for both, no-one will ever have noticed. Annoyingly, Linux and macOS disagree about what statfs::f_bsize means, and whether statfs::f_iosize and statfs::f_frsize exist (each has one or the other, depending on what f_bsize *doesn't* mean to them). This mess is presumably why statvfs exists. Unfortunately, statvfs on macOS at least doesn't contain the file system type information. So we either need to do *both* statfs() and statvfs() for macOS, or we need to take into account the different fields. This patch adds an #ifdef outside of portability.h because I wasn't sure we actually wanted to add statfs_best_transfer_size() and statfs_real_block_size() functions to lib for this. But that's an easy cleanup if desired.

2021-02-20Fix df on macOS.Elliott Hughes
On Linux, struct statvfs' f_bsize and f_frsize seem to be interchangeable. On macOS, they're wildly different. f_bsize is the "preferred length of I/O requests for files on this file system" (corresponding to statfs::f_iosize), and f_frsize is the "size in bytes of the minimum unit of allocation on this file system" (corresponding to statfs::f_bsize. POSIX appears to say nothing about the interpretation of these fields, but man7.org's statvfs(2) page is quite clear that statvfs::f_blocks, for example, is in units of f_frsize, not f_bsize. This is the only place in the tree where we use statvfs::f_bsize (other than the stat(1) output that's supposed to be f_bsize and that has a corresponding f_frsize dual anyway. I've removed the Apple-specific #define f_frsize in portability.h because that seems to have been from my previous attempt to understand what was going on here. The output of the relevant stat(1) fields on macOS are the same before/after this patch. This makes toybox df's output match the system's df on a MacBook Pro running macOS 11.2.1. Tested on a Raspberry Pi 400 running Linux too, where I see no change in the output before/after this patch.

2021-02-14Add find -executableRob Landley
Requested by aheirman on github: uses access(X_OK) which checks access control lists as well as permissions, and that _we_ can access them (u+x could be owned by a different user)...

2021-02-09ulimit: include descriptions and units.Elliott Hughes
Also reorder the --help output to separate the "whats" from the "hows", as with other commands that have lots of options, and add units to the help too.
2021-02-08Yi-Yo Chiang reported that readlink() failures could corrupt archiveRob Landley
by not writing as much payload as the header promised.
2021-02-08Have xclose() perform the fd != -1 test.Rob Landley
2021-02-07Remove unused function.Rob Landley
Ethan Sommer noticed that chown is using chgrp_main() due to OLDTOY, so the wrapper function isn't needed.
2021-02-07Add lots of "static" annotations, make a couple things use FLAG() macros, etc.Rob Landley
2021-02-06netstat: various fixes.Elliott Hughes
Avoid fgets() into toybuf other than to skip header lines, preferring fscanf() or xgetline() instead. Remove the early returns if we fail to skip a header line (fixes #62). Fix `netstat -xl` which was previously broken (because only -a would include listening sockets). Fix a variety of formatting issues, bringing the diff between toybox netstat and net-tools netstat down (which was what I used for testing). Use FLAG() more consistently.
2021-02-06Cleanup pass on netstat.Rob Landley
2021-02-03Cleanup pass on modprobe.Rob Landley
I need to set up a test environment for this...
2021-02-01Minor tweak.Rob Landley
2021-02-01rm: Check file existence with lstat() explicitly if "-f" is specifiedYi-Yo Chiang
Instead of unlink() && check errno, call lstat() explicitly to check file existence if "-f" is specified. There is a regression when if the path to be removed is nonexistence and within a readonly filesystem, then unlink() could set the EROFS errno instead of ENOENT, thus screwing up the output of `rm`.
2021-02-01The new TEST_GLUE config symbol for [ ] can't have TOYBOX prefixRob Landley
or else singlemake enables it for all commands. (I was trying to move it out of the command namespace, but it's not a global config option either...)

2021-01-26A few more getty cleanups.Rob Landley
2021-01-26getty/telnet/tftpd: minor cleanup.Elliott Hughes
Remove STDIN_FILENO and use FLAG(). Use xsetspeed() rather than have a duplicate table. Inline getty's print_prompt(). There's still a lot of cleanup needed here, in particular use of toybuf and removal of the inappropriately-named HOSTNAME_SIZE (and ideally sharing that logic with login(1) which already contains a better implementation of it).
2021-01-23Fix grep bug where -f /dev/null added "" regex matching everything,Rob Landley

2021-01-07new toy: base32Moritz Röhrich
Add new toy `base32`. Add tests for `base32`. base32 is added by adapting the base64 encode/decode function to also do base32 encoding/decoding. Then their respective main functions set up the global parameter `n` to be the number of bits used in the encoding (5 for base32 and 6 for base64) and `align` to align the result to a certain length via padding. These are deliberately kept as parameters to enable future expansion for other bases easily.
2021-01-06seq: always xwrite.Elliott Hughes
Pointed out by the compiler combined with glibc's use of __attribute__((__warn_unused_result__)) on write().

2020-12-19FS_ENCRYPT_FL introduced too recently to depend on, use constant.Rob Landley
Note: can't put in portability.h because it's a linux/ include.
2020-12-18seq.c: fix itoa for INT_MIN in case itoa gets used elsewhere.Elliott Hughes
It can't actually be used for INT_MIN in the current context because the `dd += increment` on line 100 means that even if "last" is INT_MIN, we won't take the fast path because INT_MIN - 1 isn't representable.
2020-12-16chmod.c: mask out the file type bits.Elliott Hughes
The kernel will do this for us on both Linux and macOS, but error messages are a bit misleading if we don't do it ourselves --- it can look as if the failure is because of the type bits.
