Set sysctl fs.suid_dumpable = 2
This allows suid processes to dump core according to kernel.core_pattern
setting. LEDE typically uses suid to drop root priviledge rather than
gain it but without this setting any suid process would be unable to
produce coredumps (e.g. dnsmasq)
Processes still need to set a non zero core file process limit ('ulimit
-c unlimited' or if procd used 'procd_set_param limits
core="unlimited"') in order to produce a core. This setting removes an
obscure stumbling block along the way.
>From https://www.kernel.org/doc/Documentation/sysctl/fs.txt
suid_dumpable:
This value can be used to query and set the core dump mode for setuid
or otherwise protected/tainted binaries. The modes are
0 - (default) - traditional behaviour. Any process which has changed
privilege levels or is execute only will not be dumped.
1 - (debug) - all processes dump core when possible. The core dump is
owned by the current user and no security is applied. This is
intended for system debugging situations only. Ptrace is unchecked.
This is insecure as it allows regular users to examine the memory
contents of privileged processes.
2 - (suidsafe) - any binary which normally would not be dumped is dumped
anyway, but only if the "core_pattern" kernel sysctl is set to
either a pipe handler or a fully qualified path. (For more details
on this limitation, see CVE-2006-2451.) This mode is appropriate
when administrators are attempting to debug problems in a normal
environment, and either have a core dump pipe handler that knows
to treat privileged core dumps with care, or specific directory
defined for catching core dumps. If a core dump happens without
a pipe handler or fully qualifid path, a message will be emitted
to syslog warning about the lack of a correct setting.

Bug introduced with 6713694.
I did not count on procd handling reload as mentioned
in this doc:
https://wiki.openwrt.org/inbox/procd-init-scripts
```
procd_set_param file /var/etc/your_service.conf # /etc/init.d/your_service reload will restart the daemon if these files have changed
procd_set_param netdev dev # likewise, except if dev's ifindex changes.
procd_set_param data name=value ... # likewise, except if this data changes.
```
The service would be restarted regardless of any of those params.

This was also working before, with a slightly
different semantic.
[ Original semantic ]
If no reload hooks was implemented, the default one would
kick in, it would return fail, and restart would happen.
This would happen also in the case where a reload hook
would be implemented, it would fail, and it would restart
the service.
[ New semantic ]
The default reload hook calls restart.
Services can implement their own reload.
If reload fails, then the '/etc/init.d/<service> reload'
would return a non-zero code, and the caller can choose
a way to handle this.

If only a single opkg control file exists (which can happen with
CONFIG_CLEAN_IPKG), grep would not print the file name by default. Instead
of forcing it using -H, we just switch to -l (print only file names) and
get rid of the cut.
Add -s to suppress an error message when no control files exist.

which looks pretty bad, and is even worse if someone writes only "service" without arguments, as it will print " does not exist. " which is confusing.
with this commit it looks like this:

Currently, the wifi detection script is executed as part of
the (early) boot process. Pluggable wifi USB devices, which
are inserted at a later time are not automatically
detected and therefore they don't show up in LuCI.
A user has to deal with wifi detection manually, or restart
the router.
However, the current "sleep 1" window - which the boot
process waits for wifi devices to "settle down" - is too
short to detect wifi devices for some routers anyway.
For example, this can happen with USB WLAN devices on the
WNDR4700. This is because the usb controller needs to load
its firmware from UBI and initialize, before it can operate.
The issue can be seen on a BT HomeHub 5A as well as soon as
the caldata are on an ubi volume. This is because the ath9k
card has to be initialized by owl-loader first. Which has to
wait for the firmware extraction script to retrieve the pci
initialization values inside the caldata.
This patch moves the wifi configuration to hotplug scripts.
For mac80211, the wifi configuration will now automatically
run any time a "ieee80211" device is added. Likewise
broadcom-wl's script checks for new "net" devices which
have the "wl$NUMBER" moniker.
Issues with spawning multiple interface configuration - in
case the detection script is run concurrently - have been
resolved by using a named section for the initial
configuration. Concurrent configuration scripts will now
simply overwrite the same existing configuration.
A workaround which preserves the "sleep 1" window for just
the first boot has been added. This allows the existing
brcm47xx boot and mvebu uci-default scripts to correctly
setup the initial mac addresses and regulatory domain.
And finally, the patch renames the "wifi detect" into
"wifi config". As the script no longer produces any output
that has to be redirected or appended to the configuration
file.
Thanks to Martin Blumenstingl for helping with the implementation
and testing of the patch.

Previously, wifi detect simply dumped its generated wireless
configuration to STDOUT. A second step was needed to append
the configuration to /etc/config/wireless (or create it, if
it didn't exist).
With this patch, The wifi detection script will now use uci
to update the wireless configuration directly.
This patch also makes the initially created wifi-iface a
named section ('default_radio$X' for mac80211 and
'default_wl$X' for broadcom). With this change, uci will
not print the cfgHASH to STDOUT (which would now corrupt
the wireless configuration). It will also prevent adding
duplicated wifi interface configurations, if the wifi
configuration is run concurrently.

We need to tell hwclock with -u commandline option, that we would like
to keep our RTC clock in UTC timezone. Linux kernel expects RTC in UTC
timezone anyway.
In current state of things, we don't tell hwclock to load/store time
from/to RTC in UTC timezone so it uses the timezone from the system
time. If it's set to different timezone then UTC, sysfixtime is going to
screw the time in RTC.
I've following in the setup script:
uci set system.@system[0].timezone='CET-1CEST,M3.5.0,M10.5.0/3'
uci set system.@system[0].zonename='Europe/Prague'
I've this RTC setup (rtc1 is RTC on i.MX6 SoC, rtc0 is battery backed RTC mcp7941x):
rtc-ds1307 3-006f: rtc core: registered mcp7941x as rtc0
snvs_rtc 20cc000.snvs:snvs-rtc-lp: rtc core: registered 20cc000.snvs:snvs-r as rtc1
Then we can experience following (current time is 10:15am):
$ date
Fri Oct 21 10:15:07 CEST 2016
$ hwclock -r -f /dev/rtc0
Fri Oct 21 08:14:46 2016 0.000000 seconds
$ hwclock -u -r -f /dev/rtc0
Fri Oct 21 10:14:46 2016 0.000000 seconds
And after current broken sysfixtime:
$ /etc/init.d/sysfixtime stop
$ date
Fri Oct 21 10:15:25 CEST 2016
$ hwclock -r -f /dev/rtc0
Fri Oct 21 10:15:31 2016 0.000000 seconds
Now we've time in our battery backed RTC in CEST timezone instead of
UTC. Then once again, but with this patch applied to sysfixtime, where
hwclock is using correctly the -u parameter:
$ /etc/init.d/sysfixtime stop
$ date
Fri Oct 21 10:15:53 CEST 2016
$ hwclock -r -f /dev/rtc0
Fri Oct 21 08:15:55 2016 0.000000 seconds

This commit:
1) seed /dev/urandom with the saved seeds as early as possible
(see /lib/preinit/81_urandom_seed)
2) save a seed at /etc/urandom.seed if it doesn't exists
3) save a new seed each boot at "system.@system[0].urandom_seed"
(see /etc/init.d/urandom_seed)
We use getrandom() so we are sure /dev/urandom pool is initialized
Seed size is 512 bytes (ie /proc/sys/kernel/random/poolsize / 8)
it's the same size as in ubuntu 14.04 and all systemd systems
Seeding /dev/urandom doesn't change entropy estimation, so we still have
"random: ubus urandom read with 4 bits of entropy available"
messages in the logs, but we can now ignore them if
after "urandom-seed: Seeding with ..." message

dnsmasq maintains dnsmasq.time across reboots and uses it as a means of

last time that dnsmasq considered current even though that time is in

fail thus defeating any ntp based mechanisms for setting the clock

In theory the process is defeated by any files in /etc that are newer
than /etc/dnsmasq.time however dnsmasq now updates the file's timestamp
