Re: [OpenWrt-Devel] milliseconds time measurements
not possible to get more resolution than 1 second, at least with
the
date command. I'd like to know if there's a way to get a resolution
you can start with 'date +%s'
the tic() toc() approach is nice, here is what
we do to measure exact time between 2 events:
read t1 trash /proc/uptime
do_something()
read t2 trash /proc/uptime
duration=$(( ${t2//./} - ${t1//./} ))
logger -s lasts $(( $duration / 100 )).$(( $duration % 100 )) sec
which outputs something like:
lasts 7.64 sec

[OpenWrt-Devel] [PATCH] kmod-batman-adv: Use current /lib/functions/network.sh in hotplug.d scripts
In legacy ubnt2 devices, when trying to bring 3 VAPs, one in adhoc
mode managed with batman-adv, a race condition occurs and /var/state
doesn't get the .ifname updated quickly enough at boot time. Using
(the newer) ubus call infrastructure overcomes the race condition.

hi. why did you include that file twice? is there any reason to not do a
single include in the beginning of the the script?

[OpenWrt-Devel] Snapshot buildbots: two buildslaves (Nico and Carme) upload nothing and discard binaries
Nico and Carme, two buildslaves doing the trunk snapshots upload nothing and discard the compiled firmwares. I hate seeing scarce resources wasted, so I am bugging about this. Those two are doing 4/9 of the simultaneous builds, so quite a large amount of work gets partially wasted. Due to these faulty buildbots, xburst has not seen a new binary at http://downloads.openwrt.org/snapshots/trunk/ in 14 days, despite it having been compiled succesfully three times after that ( http://buildbot.openwrt.org/builders/xburst ). It has always got either carme or nico :-( Same goes also for ixp4xx ( http://buildbot.openwrt.org/builders/ixp4xx ). It has been compiled several times succesfully after the server breakdown, but as the buildslave has always been carme or nico, there still are no binaries at all for ixp4xx. Both seem to fail for SSH key reasons, or something like that.

[OpenWrt-Devel] [PATCH] image.mk: don't squash file permissions in JFFS2 images
Currently we call mkfs.jffs2 --squash, which will change both file permissions and owners. If we have some file with suid bits, it will clear these bits. Thus it's enough to just squash file owners, by replacing that argument to --squash-uids.

[OpenWrt-Devel] Support for musl libc in OpenWrt
Hi All, Support for musl libc in OpenWrt has been added in revision r34314, this was tested against: - X86 in VirtualBox - X86_64 with UML - ARM with the realview target Note that the following issues are known: - unable to complete libstdc++ build due to some missing declarations (WIP) - MIPS and MIPSel ports are not functionnal (details below) - PowerPC has not been tested at all due to lack of hardware/emulation target I did not try yet to compile our entire set of packages besides the one pre-selected in trunk, so you will certainly encounter some breakage due to musl being more strict about header inclusions and declarations than uClibc and (e)glibc. Have fun! -- MIPS and MIPSel specific issues: using qemu's binary emulation (qemu-mips[el]) against a statically linked binary works, a dynamic binary makes my host qemu segv. Using qemu-system-mips[el], the binary segfaults while being executed by the kernel. So far I have not had the time to debug this further. -- Florian ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
