2020-12-06unicode: new toy.Elliott Hughes
Based loosely on the Plan9/Inferno utility, and a convenient way to go back and forth between code points and utf8 sequences. This patch also fixes a couple of bugs in wctoutf8 (and the tests for this toy effectively serve as unit tests for wctoutf8/utf8towc).

Add new toy `pwgen`. A usefule password generation utility.
2020-12-05tr: fix pathological flushing.Elliott Hughes
The AOSP build doesn't use tr (or anything that's still in pending), but the kernel folks have been more aggressive. They found that tr's pathological flushing was adding minutes to their build times. Just removing the fflush() made tr significantly faster for my trivial test, but still slow, with all the time going into stdio. Rewriting the loop to modify toybuf in place and then do one write per read made most of the difference, but special-casing the "neither -d nor -s" case made a measurable difference too on a Xeon. Bug: http://b/174773617

Use 0 optstr prefix, fix bug initializing toys.envc one too low.
2020-11-12readelf: harden against invalid input.Elliott Hughes
I also promised to fix readelf. Where in file(1) I made no attempt to say what was bad (or even to change `goto bad` to explicitly say that *anything* was bad), I believe that readelf is much more likely to be shown invalid ELF files, and that it would be useful to have some clue as to what's wrong. Relatedly, this patch removes all existing error_exit() calls in case it's being used on multiple files. Again, this survived ~24hrs of AFL++ trying to blow its house down. Test: ~/AFLplusplus/afl-fuzz -i tests/files/elf -o fuzz-out -- ./readelf -a @@

2020-10-20Can't call daemon() on nommu.Rob Landley
2020-10-19More tests, and a workaround to pass one of them.Rob Landley
(The bug is that "echo hello \" followed by just enter should end the $PS2 state but it persists when the line is empty because resulting collated line still ends with \ so it wants another line.)
2020-10-19Implement source, fix empty ${x-alt}, use %zu as suggested by e5ten.Rob Landley
2020-10-15stty: don't mangle c_iflags.Elliott Hughes
Fixes https://github.com/landley/toybox/issues/251 where `stty 300` was mangling c_iflags to 0x300 because even if we don't match a full hex specification of struct termios, sscanf() will have overwritten the first value, which is c_iflag.

2020-09-23Only attempt to truncate regular files in dd.Rob Landley
2020-09-23Add ftruncate logic to handle non-regular filesChris Sarra
ftruncate was failing on device files, leading to whole dd.c failures. This patch allows us to dump device files.

2020-09-10Add ipv6 support to wget.cChris Sarra
2020-09-05Fix segfault for sh -c 'echo {a..Z}'Rob Landley
Bash produces different output for that test, but I'm not sure I care? http://lists.landley.net/pipermail/toybox-landley.net/2020-September/011990.html The problem is parse_word() guarantees its output's quotes/escapes are completed, but brace expansion happens after parse_word() and thus violating assumptions later code depends on to not do redundant error checking. The easy fix is to escape punctuation produced by parse_word (which in bash can only happen when you span upper and lower case ranges so "\" is the only interesting character). I could special case this to match bash exactly, but I'm waiting for someone to complain instead.

2020-08-24Cleanup watchdog.c, as described on the list.Rob Landley
2020-08-24Introducing toys/pending/watchdog.cChris Sarra via Toybox
This patch introduces a simple watchdog implementation for toybox. We send the appropriate ioctls to set the relevant timeouts, and intercept signals to safely shut down if required.
2020-08-14cleanup: use FLAG() macros, inline parse_arguments(), STDIN_FILENO is 0.Rob Landley
2020-08-12getty: ensure utmp is updated.Elliott Hughes
The key issues here turned out to be that getty is responsible for creating the file if it doesn't exist, and that the -H flag doesn't control whether utmp is updated, but whether or not to override the hostname within the utmp entry. While I'm here switch to the more modern utx APIs that all the non-pending parts of toybox use, and remove the duplication.

2020-07-05wget: do not append toybox version at runtimeAriadne Conill
The sprintf() call, while technically valid (17 bytes fits in an 18 byte allocation) trips Alpine fortify-headers due to checking for allocations that could potentially overrun. The call is pointless anyway -- as we are appending a constant to another constant, it is better to just let the compiler do so and calculate the size. This is supported by ISO C89 and later, and thus any compiler that would be used to compile toybox. Signed-off-by: Ariadne Conill <ariadne@dereferenced.org>

2020-07-05dhcp6: use portable s6_addr instead of linux kernel-specific __in6_u.__u6_addr8Ariadne Conill
The glibc headers also provide that member, but s6_addr is the portable way. This fixes compilation on musl libc. Signed-off-by: Ariadne Conill <ariadne@dereferenced.org>
