2020-06-11hwclock: just assume /dev/rtc0.Elliott Hughes
(Apologies for the length of this commit message, but it's not entirely clear how we arrived at our present state, and right now all three of toybox, busybox, and util-linux differ from each other. And it took a week of arguments behind the scenes to agree on what we thought was the right behavior, which seemed worth capturing for posterity.) This reverts my change ef0546d4f536f42a57af4c32bd37f7fd752d10c2 from 2015. The commit message back then claimed: For systems using /dev/rtcN, /dev/rtc0 isn't necessarily the RTC that's used to provide the system time at boot time. We need to search for the RTC whose /sys/class/rtc/rtcN/hctosys contains "1". A few things to note here: 1. I can't find any historical motivation for this change. There's no bug, there's no internal email thread, and I can't even find anything referring to devices using anything other than /dev/rtc0. 2. It turns out (though this wasn't true at the time) that the kernel since 4.19 interprets hctosys as the RTC that *did* set the clock, not the RTC that *should* set the clock. 3. That's not an academic difference. If you have a cheap RTC that isn't battery-backed, or you have an RTC whose battery died, and you're using Linux 4.19 or later, you will boot with no RTC having hctosys=1. 4. An actual SoC vendor has hit this in practice. My original toybox patch appears to be equivalent to code in the Android frameworks, which -- under the auspices of the SoC vendor's bug -- I'm about to replace with code that checks "/dev/rtc" first, then "/dev/rtc0", then fails hard. (Strictly, it's this copy of the search that's causing the SoC vendor issues. AFAIK no-one's using hwclock/rtcwake except interactively. And even if they are, Android devices ship with [at least] two copies of toybox, so code/scripts on the vendor partition will continue to run the vendor copy of toybox they were developed against, and a newer toybox elsewhere on the system won't affect them.) All Android devices (and emulators) available to me at the moment use /dev/rtc0, but supporting /dev/rtc gives a workaround for anyone who really insists on using an RTC other than /dev/rtc0. That said, the Generic Kernel Image (GKI) always assumes /dev/rtc0, so going forward /dev/rtc0 is always the right choice. I did consider making toybox hwclock try /dev/rtc, /dev/rtc0, and /dev/misc/rtc -- and even wrote the code for that first -- but strace shows that busybox and util-linux's hwclock implementations differ in the order in which they try these (busybox tries /dev/rtc first, util-linux tries /dev/rtc0 first). Given that util-linux seems like the more canonical precedent, trying /dev/rtc0 and then falling back to /dev/rtc would offer no advantage to Android users (and would seem to be just another stumbling block in getting everyone to a world where /dev/rtc0 is "the" system RTC). Note that rtcwake is unaffected by all this, because the toybox and util-linux implementations both default to only trying /dev/rtc0 already. Bug: https://issuetracker.google.com/158051176

2020-06-09chmod: fix -R and dangling symlinks.Elliott Hughes
Found trying to run the libc++ tests. For coreutils, `info chmod` says: 'chmod' ignores symbolic links encountered during recursive directory traversals. Bug: http://b/155809792

2020-06-02Remove getevent from roadmap: it's an android board bringup tool built byRob Landley
running a python script against the kernel headers, more or less a hardware debugging tool that doesn't really benefit from being in-tree nor does it need to ship on deployed systems. (And it should probably be a kernel module.)
2020-06-01Fix tests.Rob Landley
Includes removing a test that's just gratuitously checking whether or not a corner case gratuitously differs from coreutils. (So what? Who cares?)

Yes, I need to convert to README.md, it's on the todo list...
2020-05-29Replace more SKIP_HOST with toyonly.Rob Landley
SKIP_HOST won't run a test when TEST_HOST set, but toyonly runs its arguments whenever testing toybox (including when the host version is toybox).

2020-05-28portability.c: fix macOS build.Elliott Hughes
I suspect the rest of the non-POSIX signals might end up like this, but this is the subset that needs to be #ifdef'ed to fix the macOS build.

2020-05-27dhcpd: fix warningsEthan Sommer
Add presumably intended conversion specifier for gconfig.valid_lifetime as it is an argument to error_msg despite the format string having no conversion specifiers. Remove always true false inverse check for address of array gstate.rcvd.rcvd_pkt6.transaction_id.

2020-05-24Cleanup openvt.Rob Landley
2020-05-24Cleanup blkdiscard.Rob Landley
Yeah, this limits 32 bit support, but that's a "fix it properly in lib/args.c or don't care" issue. Why work around it here when truncate -s doesn't?
2020-05-23Ahem: have the backgrounding test actually background.Rob Landley
Point is to make sure the consumer waits for all output, not for process exit.
