cpp-httplib sets IPV6_V6ONLY to false on it's sockets.
On FreeBSD, this makes all ipv4 addresses get get prefixed with ::ffff:
it makes them IPv6 addresses mapped to v4.
This is a partial fix for #2151. The cli will work again.
Something should probably also be adjusted with the httplib.
If you want to, for example, use the `allowManagementFrom` option in
local.conf
you will need to prefix it with "::ffff:", "::ffff:1.2.3.4"
which is a little surprising and inconsistent between BSD and other OSs.
Want to show it in UIs. So need to get it via API.
It's also a pain to look up. You have to go to external docs.
zerotier-cli info -j
```json
"config": {
"settings": {
"allowTcpFallbackRelay": true,
"forceTcpRelay": true,
"homeDir": "/Library/Application Support/ZeroTier/One",
```
```sh
curl -s -X POST "http://localhost:9993/controller/network/abcdabcdabcdabcd/member/1122334455"
```
Would return 200 and ZT_HOME/controller.d/abcdabcdabcdabcd/members/1122334455
would be created. Without a ZT_HOME/controller.d/abcdabcdabcdabcd.json
Then other parts of the system mistakenly think a abcdabcdabcdabcd
network sorta kinda exists and then fail in weird ways.
There was as Windows directory traversal bug in the static
file server feature. We don't use that feature, so we are ok.
We are going to use that feature soon, so we are
taking the opportunity to update.
Add /unstable/controller/network endpoint
Similar to /unstable/controller/network/{id}/member, it returns actual network objects,
instead of just network ids.
Also includes the total network count,
and each network has it's member counts in meta{}.
The current api at /controller/network/1111111111767f2f/member
Lists only the members' ID and revision number.
If you want details, you have to query each specific member.
So if you want to make a members list, and you have
10000 members on a network, you need to make
10000 http requests.
It's also in a hard to specify and use shape
{ [member-id-1]: 13, [member-id-2]: 14, ... }
GET http://localhost:9993/unstable/controller/network/1111111111767f2f/member ->
```
{
data: [ {...member1}, {...member2}, ...],
meta: { totalCount: 4, authorizedCount: 3 }
}
```
This makes switching between physical networks
with full tunnel mode enabled more reliable.
There were issues with the physical default route or device
changing.

If that's better we can change the PR.
Since now there are no callers of getAuthURL I deleted it.

* Exit if loading an invalid identity from disk
Previously, if an invalid identity was loaded from disk, ZeroTier would
generate a new identity & chug along and generate a brand new identity
as if nothing happened. When running in containers, this introduces the
possibility for key matter loss; especially when running in containers
where the identity files are mounted in the container read only. In
this case, ZT will continue chugging along with a brand new identity
with no possibility of recovering the private key.

* fix warning: 'OS_STRING' macro redefined [-Wmacro-redefined] (#2064)
Even though this is in ext, these particular chunks of code were added
by us, so are ok to modify.
* Apply default route a different way - macOS
The original way we applied default route, by forking
0.0.0.0/0 into 0/1 and 128/1 works, but if mac os has any networking
hiccups -if you change SSIDs or sleep/wake- macos erases the system default route.
And then all networking on the computer is broken.
to summarize the new way:
allowDefault=1
```
sudo route delete default 192.168.82.1
sudo route add default 10.2.0.2
sudo route add -ifscope en1 default 192.168.82.1
```
gives us this routing table
```
Destination Gateway RT_IFA Flags Refs Use Mtu Netif Expire rtt(ms) rttvar(ms)
default 10.2.0.2 10.2.0.18 UGScg 90 1 2800 feth4823

```
sudo route delete default
sudo route delete -ifscope en1 default
sudo route add default 192.168.82.1

Notice the I flag, for -ifscope, on the physical default route.
route change does not seem to work reliably.
* fix docker tag for controllers (#2066)
* Update build.sh (#2068)
fix mkwork compilation errors
* Fix network DNS on macOS
It stopped working for ipv4 only networks in Monterey.
See #1696
We add some config like so to System Configuration
```
scutil
show State:/Network/Service/9bee8941b5xxxxxx/IPv4
<dictionary> {
Addresses : <array> {
0 : 10.2.1.36
}
InterfaceName : feth4823
Router : 10.2.1.36
ServerAddress : 127.0.0.1
}
```
* Add search domain to macos dns configuration
Stumbled upon this while debugging something else.
If we add search domain to our system configuration for
network DNS, then search domains work:
```
ping server1 ~
PING server1.my.domain (10.123.3.1): 56 data bytes
64 bytes from 10.123.3.1
```
* Fix reporting of secondaryPort and tertiaryPort See: #2039
* Fix typos (#2075)
* Disable executable stacks on assembly objects (#2071)
Add `--noexecstack` to the assembler flags so the resulting binary
will link with a non-executable stack.
Fixeszerotier/ZeroTierOne#1179
Co-authored-by: Joseph Henry <joseph.henry@zerotier.com>
* Test that starting zerotier before internet works
* Don't skip hellos when there are no paths available
working on #2082
* Update validate-1m-linux.sh
* Save zt node log files on abort
* Separate test and summary step in validator script
* Don't apply default route until zerotier is "online"
I was running into issues with restarting the zerotier service while
"full tunnel" mode is enabled.
When zerotier first boots, it gets network state from the cache
on disk. So it immediately applies all the routes it knew about
before it shutdown.
The network config may have change in this time.
If it has, then your default route is via a route
you are blocked from talking on. So you can't get the current
network config, so your internet does not work.
Other options include
- don't use cached network state on boot
- find a better criteria than "online"
* Fix node time-to-online counter in validator script
* Export variables so that they are accessible by exit function
* Fix PortMapper issue on ZeroTier startup
See issue #2082
We use a call to libnatpmp::ininatpp to make sure the computer
has working network sockets before we go into the main
nat-pmp/upnp logic.
With basic exponenetial delay up to 30 seconds.
* testing
* Comment out PortMapper debug
this got left turned on in a confusing merge previously
* fix macos default route again
see commit fb6af1971 * Fix network DNS on macOS
adding that stuff to System Config causes this extra route to be added
which breaks ipv4 default route.
We figured out a weird System Coniguration setting
that works.
--- old
couldn't figure out how to fix it in SystemConfiguration
so here we are# Please enter the commit message for your changes. Lines starting
We also moved the dns setter to before the syncIps stuff
to help with a race condition. It didn't always work when
you re-joined a network with default route enabled.
* Catch all conditions in switch statement, remove trailing whitespaces
* Add setmtu command, fix bond lifetime issue
* Basic cleanups
* Check if null is passed to VirtualNetworkConfig.equals and name fixes
* ANDROID-96: Simplify and use return code from node_init directly
* Windows arm64 (#2099)
* ARM64 changes for 1.12
* 1.12 Windows advanced installer updates and updates for ARM64
* 1.12.0
* Linux build fixes for old distros.

* Exit if loading an invalid identity from disk
Previously, if an invalid identity was loaded from disk, ZeroTier would
generate a new identity & chug along and generate a brand new identity
as if nothing happened. When running in containers, this introduces the
possibility for key matter loss; especially when running in containers
where the identity files are mounted in the container read only. In
this case, ZT will continue chugging along with a brand new identity
with no possibility of recovering the private key.

* fix warning: 'OS_STRING' macro redefined [-Wmacro-redefined] (#2064)
Even though this is in ext, these particular chunks of code were added
by us, so are ok to modify.
* Apply default route a different way - macOS
The original way we applied default route, by forking
0.0.0.0/0 into 0/1 and 128/1 works, but if mac os has any networking
hiccups -if you change SSIDs or sleep/wake- macos erases the system default route.
And then all networking on the computer is broken.
to summarize the new way:
allowDefault=1
```
sudo route delete default 192.168.82.1
sudo route add default 10.2.0.2
sudo route add -ifscope en1 default 192.168.82.1
```
gives us this routing table
```
Destination Gateway RT_IFA Flags Refs Use Mtu Netif Expire rtt(ms) rttvar(ms)
default 10.2.0.2 10.2.0.18 UGScg 90 1 2800 feth4823
default 192.168.82.1 192.168.82.217 UGScIg
```
allowDefault=0
```
sudo route delete default
sudo route delete -ifscope en1 default
sudo route add default 192.168.82.1
```

* fix docker tag for controllers (#2066)
* Update build.sh (#2068)
fix mkwork compilation errors
* Fix network DNS on macOS
It stopped working for ipv4 only networks in Monterey.
See #1696
We add some config like so to System Configuration
```
scutil
show State:/Network/Service/9bee8941b5xxxxxx/IPv4
<dictionary> {
Addresses : <array> {
0 : 10.2.1.36
}
InterfaceName : feth4823
Router : 10.2.1.36
ServerAddress : 127.0.0.1
}
```
* Add search domain to macos dns configuration
Stumbled upon this while debugging something else.
If we add search domain to our system configuration for
network DNS, then search domains work:
```
ping server1 ~
PING server1.my.domain (10.123.3.1): 56 data bytes
64 bytes from 10.123.3.1
```
* Fix reporting of secondaryPort and tertiaryPort See: #2039
* Fix typos (#2075)
* Disable executable stacks on assembly objects (#2071)
Add `--noexecstack` to the assembler flags so the resulting binary
will link with a non-executable stack.
Fixeszerotier/ZeroTierOne#1179

* Test that starting zerotier before internet works
* Don't skip hellos when there are no paths available
working on #2082
* Update validate-1m-linux.sh
* Save zt node log files on abort
* Separate test and summary step in validator script
* Don't apply default route until zerotier is "online"
I was running into issues with restarting the zerotier service while
"full tunnel" mode is enabled.
When zerotier first boots, it gets network state from the cache
on disk. So it immediately applies all the routes it knew about
before it shutdown.
The network config may have change in this time.
If it has, then your default route is via a route
you are blocked from talking on. So you can't get the current
network config, so your internet does not work.
Other options include
- don't use cached network state on boot
- find a better criteria than "online"
* Fix node time-to-online counter in validator script
* Export variables so that they are accessible by exit function
* Fix PortMapper issue on ZeroTier startup
See issue #2082
We use a call to libnatpmp::ininatpp to make sure the computer
has working network sockets before we go into the main
nat-pmp/upnp logic.
With basic exponenetial delay up to 30 seconds.
* testing
* Comment out PortMapper debug
this got left turned on in a confusing merge previously
* fix macos default route again
see commit fb6af1971 * Fix network DNS on macOS
adding that stuff to System Config causes this extra route to be added
which breaks ipv4 default route.
We figured out a weird System Coniguration setting
that works.
--- old
couldn't figure out how to fix it in SystemConfiguration
so here we are# Please enter the commit message for your changes. Lines starting
We also moved the dns setter to before the syncIps stuff
to help with a race condition. It didn't always work when
you re-joined a network with default route enabled.
* Catch all conditions in switch statement, remove trailing whitespaces
* Add setmtu command, fix bond lifetime issue
* Basic cleanups
* Check if null is passed to VirtualNetworkConfig.equals and name fixes
* ANDROID-96: Simplify and use return code from node_init directly
* Windows arm64 (#2099)
* ARM64 changes for 1.12
* 1.12 Windows advanced installer updates and updates for ARM64
* 1.12.0
* Linux build fixes for old distros.
* release notes

}
InterfaceName : feth4823
Router : 10.2.1.36
ServerAddress : 127.0.0.1

```
The original way we applied default route, by forking
0.0.0.0/0 into 0/1 and 128/1 works, but if mac os has any networking
hiccups -if you change SSIDs or sleep/wake- macos erases the system default route.
And then all networking on the computer is broken.
to summarize the new way:
allowDefault=1
```
sudo route delete default 192.168.82.1
sudo route add default 10.2.0.2
sudo route add -ifscope en1 default 192.168.82.1
```
gives us this routing table
```
Destination Gateway RT_IFA Flags Refs Use Mtu Netif Expire rtt(ms) rttvar(ms)
default 10.2.0.2 10.2.0.18 UGScg 90 1 2800 feth4823
default 192.168.82.1 192.168.82.217 UGScIg
```
allowDefault=0
```
sudo route delete default
sudo route delete -ifscope en1 default
sudo route add default 192.168.82.1
```
Notice the I flag, for -ifscope, on the physical default route.
route change does not seem to work reliably.
* Exit if loading an invalid identity from disk
Previously, if an invalid identity was loaded from disk, ZeroTier would
generate a new identity & chug along and generate a brand new identity
as if nothing happened. When running in containers, this introduces the
possibility for key matter loss; especially when running in containers
where the identity files are mounted in the container read only. In
this case, ZT will continue chugging along with a brand new identity
with no possibility of recovering the private key.
ZeroTier should exit upon loading of invalid identity.public/identity.secret #2056
* add validation test for #2056
It doesn't work.
Not possible to fix with deficient network
stack and APIs.
ZeroTierOne-freebsd # zerotier-cli set 9bee8941b5xxxxxx allowDefault=1
400 set Allow Default does not work properly on FreeBSD. See #580

* Add a 2nd auth token for /metrics
Allows administrators to distribute a token that only has access to read
metrics and nothing else.
Also added support for using bearer auth tokens for both types of tokens
Separate endpoint for metrics #2041
* Update readme
* fix a couple of cases of writing the wrong token
getAuthURL() was not calling zeroidc::free_cstr(url);
the only place authAuthURL is called, the url can be retrieved
from the network config instead.
You could alternatively copy the string and call free_cstr in getAuthURL.
If that's better we can change the PR.
Since now there are no callers of getAuthURL I deleted it.

Switching `/t:ZeroTierOne:Rebuild` to just `/t:ZeroTierOne` allows the Windows build to use the rust cache. `/t:ZeroTierOne:Rebuild` cleared the cache before building.
refactored the old control plane code to use [cpp-httplib](https://github.com/yhirose/cpp-httplib) instead of a hand rolled HTTP server. Makes the control plane code much more legible. Also no longer randomly stops responding.

Still unknown as to why, but the call to `nc->GetProperties()` can fail
when setting a friendly name on the Windows virtual ethernet adapter.
Ensure that `ncp` is not null before continuing and accessing the device
GUID.
When adding Routes to zerotier's Managed Routes, the helper will
add a route rule to the device that does not have a via ip,
so that the address of the Destination segment cannot be routed
correctly within the container.
Here, based on the contents of the routes key in
`zerotier-cli -j listnetworks`,
by determining whether the via key has an ip address,
if it is not null, helper will no longer add route rules.
ARM Cryptography Extension is optional and not all ARM CPUs support it.
For example, the CPU in Raspberry Pi 4 does not support it.
Check for `__ARM_FEATURE_CRYPTO` before attempting to use the optional
extension.
`__ARM_FEATURE_CRYPTO` is defined by both clang and gcc when the target
has the cryptography extension.
Fixes#1854.
Client side:
* Fix compatibility with OneLogin
* Requested scopes vary by OIDC provider. Different providers have different
Controller side:
*Update Postgres queries to latest Central schema
* Added Central Controller support for the different providers
* Base OIDC provider details are still attached to an org. Client ID & group/email lists are now associated with individual networks.
Xcode warns about "Possible misuse of comma operator here".
Comma is a sequencing operator in C++ and original code does work, but
is highly non-idiomatic.
This patch implements a "TUNNELED" status indicator and "forceTcpRelay" setting for custom relays via local.conf.
For example:
{
"settings":
{
"tcpFallbackRelay": "6.79.53.215/443",
"forceTcpRelay":true
}
}
If you have a VM host like parallels, sometimes you get these link-local
default routes:
```
netstat -nrfinet | grep "default\|\/1"
0/1 10.2.0.12 UGScg feth4823
default 192.168.82.1 UGScg en1
0/1 192.168.82.1 UGScIg en1
default link#22 UCSIg bridge101 !
128.0/1 10.2.0.12 UGSc feth4823
128.0/1 192.168.82.1 UGScI en1
```
(the link#22 one)
The _getRTEs function inclused these routes in the list it makes as like:
device: bridge101, target: 0.0.0.0/0
If it happens to be first in the list, bridge101 gets
selected as the default route.
Then Full Tunnel Mode doesn't work.
The other routes in the list are like:
device: en1 target: 192.168.1.0/24 via: metric: 0 ifscope: 0
device: en1 target: 192.168.1.1/32 via: metric: 0 ifscope: 0
We only need the device name from this, so either one will work.
Through using ndk-build, -Wno-unused-command-line-argument is passed in
somewhere in the pipeline and hides this warning.

The actual value being passed to command-line was:

Surface Addresses are the addresses that
the roots report back to you.
This is helpful for trouble shooting.
If you're behind NAT, the source port is different
than what zerotier is bound to.
If the list of surface address ports is larger than the list of
bound addresses, you are probably behind symmetric NAT.
Anways this can be added to later with a more simple
"easy" or "hard" nat computed message somewhere.
* update entrypoint.sh
- propagate TERM/QUIT/INT signals
- add some basic logging
- check for unbound variables
- update "route helper"
- run as subshell, exit if zerotier-one is unavailable so pod can be restarted
- only call `zerotier-cli` once, avoids race conditions
- only add default routes if allowDefault is enabled for that network
- add some more error handling
- sleep after all networks are processed
* switch to polling ZT service at startup

redis plus plus has an annoying feature where it will open a new
connection for each tx or pipeline by default, rather than just fetching
an existing connection from the pool. Let's change that
Port used for PortMapping was not properly randomized causing multiple clients on the same lan to request the same UPnP port, and not all routers handle this gracefully.
Also fixes issue where the portmapper wasn't started at all if a secondary port wasn't specified, or if the tertiary port was manually specified.
When I first bring up the container, I want to know I'm approving the join request for the right node. I can get the node's ZT address by manually executing `zerotier-cli info` in the node (e.g. with `docker-compose exec zerotier zerotier-cli info`) but just having it in the logs to start with is very convenient.
- Resolve issue with join not being checked properly for success without
using external tools
- Resolve issue where initial boot was not being checked properly
- Now output errors when zerotier fails to start

Proactively seek, and distribute external surface addresses
This patch introduces a new "self-awareness" behavior which proactively queries peers for external surface addresses and distributes them via PUSH_DIRECT_PATHS. This has the effect of making ZT more responsive to interface changes.
Current behavior:
Previously, this type of information was only mediated via RENDEZVOUS and was only triggered when the client detected that it no longer had a single alive path to a peer. While PUSH_DIRECT_PATHS would correctly (and often) send local addresses, this was not the case for external addresses collected from response HELLOs. This would lead to situations where only one physical address would be distributed to peers. Additionally, if a new physical interface were to be made available to the client, the client would correctly bind to it but never seek information about its external mapping from a peer, and thus the new physical interface would remain unavailable for other peers to learn about until all paths on the previous interface have expired which can take a couple of minutes. In traditional usage of ZT this is not usually a problem, but it becomes a problem in the following scenarios:
Network interfaces go up and down while ZT is running (e.g. switching to LTE or WiFi from a wired connection)
Network interfaces are added or removed in multipath setups
Proposed behavior:
I propose that normal full HELLOs are sent not only on the first interface in use, but all interfaces. This causes planets to respond with a HELLO containing the surface address for each interface. We then collect each address using SelfAwareness::whoami() and distribute them via the normal PUSH_DIRECT_PATHS mechanism.
Rate gate ECHO per Path instead of per Peer
In multipath scenarios user traffic is used to judge the aliveness of a path. If the user traffic is too infrequent to establish aliveness for a given time window (say 500 ms), the bonding layer will send extra ECHOs at a maximum rate of failoverInterval / 3 (or ~ 166 ms) per path. This patch relaxes the rate-limiting of ECHOs significantly in order to prevent a non-multipath node from dropping ECHOs causing multipath nodes to erroneously judge paths to that node to be dead.
Details
This patch decreases the rate limiting from 1000 ms per peer by a factor of 6 to ~166 ms and rate limits ECHOs per Path instead of per Peer. This allows rate limiting to scale with the number of established paths to a peer.
As a result, if all 64 path slots are used a total of 64 x 6 = 384 ECHOs per second will be allowed in the most aggressive case where failoverInterval is set to 500 ms.
Add a method to "kick" the refresh thread and re-post the tokens in the case where the thread is somehow still running & controller pushes out an AUTH_REQUIRED. This situation happens in a corner case still under investigation where the controller pushes out many copies of the network config repeatedly
See issue #750.
zerotier doesn't currently set a metric on routes. Linux
takes this to mean "0", the highest priority.
Every comment in the issue is about routing between zerotier
and lan and how they conflict.
This quick change could fix this problem for most people.
The subnet route for the zerotier network, the one with no
via, is still 0 in this patch. Just the "via" routes get
higher metrics.
If for some reason, you needed your via routes to have
higher priority, you could use a prefix work-around:
192.168.1.0/25 via 10.147.17.1
192.168.1.128/25 via 10.147.17.1
consolidated everything into the single IDC struct. Should help keep from rotating the pkce token as often & causing issues with the login window flapping
and vice versa.
For issue #1104
With some printf debugging, I was seeing:
here, src fe80::3c7a:2dff:fe0c:21ed, target 10.147.20.0, matchingPrefixBits 0, mostMatchingPrefixBits 0
here, src fd8b:d512:4fd6:255:3c99:932f:2fda:6eff, target 10.147.20.0, matchingPrefixBits 0, mostMatchingPrefixBits 0
and (matchingPrefixBits >= mostMatchingPrefixBits) would be true
Then on mac, somewhere downstream from there, the default route would
get messed up:
default via 92:29:f1:6f:2f:76 dev en0
- Can now provide the following environment variables to populate
secrets (nice for kubernetes, other situations)
- ZEROTIER_API_SECRET: authtoken.secret
- ZEROTIER_IDENTITY_PUBLIC: identity.public
- ZEROTIER_IDENTITY_SECRET: identity.secret
- Joining networks by providing them as a part of docker's "command"
array should now work properly

On certain OSes (Linux & Apple) tun#, tap#, and of course zt# are blacklisted by default, this adds wg# to the list as WireGuard is a similar popular service with wg# being the default adapter name(s) by convention.
Unaligned access caused SIGBUS errors on ARMv6 and ARMv7 targets under FreeBSD.
This was also the cause of the repeating TAP devices. Each time the SIGBUS happened, the service would auto-restart itself, create a new TAP device, and then crash again.
The particular place causing the SIGBUS was:
https://github.com/zerotier/ZeroTierOne/blob/master/node/Utils.hpp#L695
Major new features are:
* **Multipath support** with modes modeled after the Linux kernel's bonding driver. This includes active-passive and active-active modes with fast failover and load balancing. See section 2.1.5 of the manual.
* **DNS configuration** push from network controllers to end nodes, with locally configurable permissions for whether or not push is allowed.
* **AES-GMAC-SIV** encryption mode, which is both somewhat more secure and significantly faster than the old Salsa20/12-Poly1305 mode on hardware that supports AES acceleration. This includes virtually all X86-64 chips and most ARM64. This mode is based on AES-SIV and has been audited by Trail of Bits to ensure that it is equivalent security-wise.
Known issues that are not yet fixed in this beta:
* Some Mac users have reported periods of 100% CPU in kernel_task and connection instability after leaving networks that have been joined for a period of time, or needing to kill ZeroTier and restart it to finish leaving a network. This doesn't appear to affect all users and we haven't diagnosed the root cause yet.
* The service sometimes hangs on shutdown requiring a kill -9. This also does not affect all systems or users.
* AES hardware acceleration is not yet supported on 32-bit ARM, PowerPC (32 or 64), or MIPS (32 or 64) systems. Currently supported are X86-64 and ARM64/AARCH64 with crypto extensions.
* Some users have reported multicast/broadcast outages on networks lasting up to 30 seconds. Still investigating.
We're trying to fix all these issues before the 1.6.0 release. Stay tuned.
Just adding it to the repo, but it still needs to be dealt with during install.
Probably put it in $ZT_HOME and then symlink to the proper place for the distro?
searches $ZT_HOME/networks.d/ for network IDs
searches HISTORY for 16 digit numbers that look like network IDs.
If a redis cluster member fails over to the slave, we'll get an error from not specifying the key for the insert. Recover from that instead of crashing the controller
On system shutdown, zerotier is stopped after the network and gets
itself into a connection timeout loop. It hits the TimeoutStopUSec= and
is forcibly killed by SIGKILL. Order zerotier after network.target so it
can shutdown gracefully while the network is still up.
From systemd.special(7):
at shutdown, a unit that is ordered after network.target will be stopped
before the network — to whatever level it might be set up then — is shut
down. It is hence useful when writing service files that require network
access on shutdown, which should order themselves after this target, but
not pull it in
* ARM32 platform build and flag fixes

* Fixed numerous other small issues and bugs such as ARM alignment issues causing crashes on some devices.
* Windows now sets the adapter name such that it is consistent in both the Windows UI and command line utilities.
Because zerotier-one depends on "one", which is a phony target,
making it relinks zerotier-one every time, which is probably
not the desired behavior.
In any case, zerotier-one, zerotier-cli, and zerotier-idtool are
real target, so they should have real dependencies and actions.
The "one" target now depends on these three files.
Behavior is mostly unchanged otherwise.
Made the smallest change I could figure out.

This commit changes the Dockerfile ot use the multi-stage build and help
to get an automated build on Docker.
The idea of the multi-stage build is to use the already stable Debian
distribution channel to provide up-to-date versions of ZeroTier.
The benefit is that it would be possible to automate the image build,
either on Docker Hub, Travis or taking advantage of the [docker-library/official-images] infrastructure.
This changes follows the best-practices suggested by
[docker-library/official-images], such as using a High Availability GPG
keyserver, providing a default CMD, allowing "bash" on `docker run` and
others.
Given that both the builder `debian:stretch` and `alpine:latest` are
official messages and have [manifests], this means that this Dockerfile
is also multi-platform. This means that this same Dockerfile will
pick-up the correct Debian package according to the architecture of the
running system during build.
With this changes we could try to promote the image to be parte of
[docker-library/official-images], and take advantage of automated
publishing of multi-architecture images. Others would be able to use
`docker run zerotier` and download the latest version appropriate to
their system.

* Fixed a bug that caused exits to take a long time on Mac due to huge numbers of redundant attempts to delete managed routes.
* Fixed a socket limit problem on Windows that caused the ZeroTier service to run out of sockets, causing the UI and CLI to be unable to access the API.
* Fixed a threading bug in the ZeroTier Core, albeit one that never manifested on the regular ZeroTier One service/client.
* Fixed a bug that could cause the service to crash if an authorized local client accessed an invalid URL via the control API. (Not exploitable since you needed admin access anyway.)

* Features and Core Improvements
* Path selection has been overhauled to improve path stability, simplify code, and prepare for multi-path and trunking in the next major release.
* This version introduces remote tracing for remote diagnostics. Network controllers can set a node (usually the controller itself) to receive remote tracing events from all members of the network or from select members. Events are only sent if they pertain to a given network for security reasons.
* Multicast replication can now be done by designated multicast replicators on a network (flagged as such at the controller) rather than by the sender. Most users won't want this, but it's useful for specialized use cases on hub-and-spoke networks and for low-power devices.
* Cryptographic performance improvements on several platforms.
* Multithreaded performance improvements throughout the code base, including the use of an inline lightweight spinlock for low-contention resources.
* Bugs fixed
* Disappearing routes on Mac (GitHub issue #600)
* Route flapping and path instability in some dual-stack V4/V6 networks
* Blacklist (in local.conf) doesn't work reliably (GitHub issue #656)
* Connection instabilities due to unsigned integer overflows in timing comparisons (use int64_t instead of uint64_t)
* Binaries don't run on some older or lower-end 32-bit ARM chips (build problem)
* ARM NEON crypto code crashes (build problem)
* Fixed some lock ordering issues revealed by "valgrind" tool
* The "zerotier-idtool" command could not be accessed from "zerotier-one" via command line switch
* Leaking sockets on some platforms when uPnP/NAT-PMP is enabled
* Fixed two very rare multithreading issues that were only observed on certain systems
* Platform-Specific Changes
* MacOS
* Installer now loads the kernel extension right away so that High Sierra users will see the prompt to authorize it. This is done in the "Security & Privacy" preference pane and must be done driectly on the console (not via remote desktop). On High Sierra and newer kexts must be authorized at the console via security settings system preferences pane.
* Windows
* The Windows installer should now install the driver without requiring a special prompt in most cases. This should make it easier for our packages to be accepted into and updated in the Chocolatey repository and should make it easier to perform remote installs across groups of machines using IT management and provisioning tools.
* The Windows official packages are now signed with an EV certificate (with hardware key).
* The Windows UI can now log into ZeroTier Central and join networks via the Central API.
* The `zerotier-idtool` command should now work on Windows without ugly hacks.
* Upgraded the installer version.
* Made a few changes to hopefully fix sporadic "will not uninstall" problems, though we cannot duplicate these issues ourselves.
* Linux
* Device names are now generated deterministically based on network IDs for all newly joined networks.
* Android
* Multicast now works on Android in most cases! Android apps can send and receive multicast and subscribe to multicast group IPs. Note that in some cases the app must bind to the specific correct interface for this to work.
* IPv6 can be disabled in UI for cases where it causes problems.

Adds a "vault" section to local.conf. Example local.conf:
{
"config": {
"vault": {
"vaultURL": "https://some.vault.host:8200",
"vaultToken": "my-super-secret-vault-token",
"vaultPath": "secure/place/to/put/identity"
}
}
Additionally, the following environment variables can be set. Environment variables override local.conf:
VAULT_ADDR
VAULT_TOKEN
VAULT_PATH
Identities will be placed in the keys "public" and "secret" under the user specified path. If no path is specified, they will be placed in the token specific cubbyhole.
If identity.public and identity.secret exist on disk and vault is configured, they will be automatically added to Vault and removed from disk.
TODO:
* Decide behavior for if Vault cannot be reached.
* Add libcurl as a dependency in Linux & Mac builds
* Add libcurl as a requirement for linux packages
When running ArchlinuxARM with 64bit support on Raspberry Pi3, the default build fails due to the architecture look-up at the beginning of the build process. A simple addition of the Armv7l section above allows the build to continue and successfully run.
There were cases in the code where time calculations and comparisons were overflowing and causing connection instability. This will keep time calculations within expected ranges.
I've only tested locally, on a power8 box running Ubuntu 16.10, but everything (and earth) checks out.
Let me know if more testing infrastructure is needed.
* Managed routes are now only bifurcated for the default route. This is a change in behavior, though few people will probably notice. Bifurcating all managed routes was causing more trouble than it was worth for most users.
* Up to 2X crypto speedup on x86-64 (except Windows, which will take some porting) and 32-bit ARM platforms due to integration of fast assembly language implementations of Salsa20/12 from the [supercop](http://bench.cr.yp.to/supercop.html) code base. These were written by Daniel J. Bernstein and are in the public domain. My Macbook Pro (Core i5 2.8ghz) now does almost 1.5GiB/sec Salsa20/12 per core and a Raspberry Pi got a 2X boost. 64-bit ARM support and Windows support will take some work but should not be too hard.
* Refactored code that manages credentials to greatly reduce memory use in most cases. This may also result in a small performance improvement.
* Reworked and simplified path selection and priority logic to fix path instability and dead path persistence edge cases. There have been some sporadic reports of persistent path instabilities and dead paths hanging around that take minutes to resolve. These have proven difficult to reproduce in house, but hopefully this will fix them. In any case it seems to speed up path establishment in our tests and it makes the code simpler and more readable.
* Eliminated some unused cruft from the code around path management and in the peer class.
* Fixed an issue causing build problems on some MIPS architecture systems.
* Fixed Windows forgetting routes on sleep/wake or in some other circumstances. (GitHub issue #465)
Version 1.2.2 fixes a few bugs discovered after the 1.2.0 release. These are:
* A bug causing unreliable multicast propagation (GitHub issue #461).
* A crash in ARM binaries due to a build chain and flags problem.
* A bug in the network controller preventing members from being listed (GitHub issue #460).
The largest new feature in 1.2.0, and the product of many months of work, is our advanced network rules engine. With this release we achieve traffic control, security monitoring, and micro-segmentation capability on par with many enterprise SDN solutions designed for use in advanced data centers and corporate networks.
Rules allow you to filter packets on your network and vector traffic to security observers. Security observation can be performed in-band using REDIRECT or out of band using TEE.
Tags and capabilites provide advanced methods for implementing fine grained permission structures and micro-segmentation schemes without bloating the size and complexity of your rules table.
See the [rules engine announcement blog post](https://www.zerotier.com/blog/?p=927) for an in-depth discussion of theory and implementation. The [manual](https://www.zerotier.com/manual.shtml) contains detailed information on rule, tag, and capability use, and the `rule-compiler/` subfolder of the ZeroTier source tree contains a JavaScript function to compile rules in our human-readable rule definition language into rules suitable for import into a network controller. (ZeroTier Central uses this same script to compile rules on [my.zerotier.com](https://my.zerotier.com/).)
It's now possible to create your own root servers and add them to the root server pool on your nodes. This is done by creating what's called a "moon," which is a signed enumeration of root servers and their stable points on the network. Refer to the [manual](https://www.zerotier.com/manual.shtml) for instructions.
Federated roots achieve a number of things:
* You can deploy your own infrastructure to reduce dependency on ours.
* You can deploy roots *inside your LAN* to ensure that network connectivity inside your facility still works if the Internet goes down. This is the first step toward making ZeroTier viable as an in-house SDN solution.
* Roots can be deployed inside national boundaries for countries with data residency laws or "great firewalls." (As of 1.2.0 there is still no way to force all traffic to use these roots, but that will be easy to do in a later version.)
* Last but not least this makes ZeroTier somewhat less centralized by eliminating any hard dependency on ZeroTier, Inc.'s infrastructure.
Our roots will of course remain and continue to provide zero-configuration instant-on deployment, a secure global authority for identities, and free traffic relaying for those who can't establish peer to peer connections.
An element of our design philosophy is "features are bugs." This isn't an absolute dogma but more of a guiding principle. We try as hard as we can to avoid adding features, especially "knobs" that must be tweaked by a user.
As of 1.2.0 we've decided that certain knobs are unavoidable, and so there is now a `local.conf` file that can be used to configure them. See the ZeroTier One documentation for these. They include:
* Blacklisting interfaces you want to make sure ZeroTier doesn't use for network traffic, such as VPNs, slow links, or backplanes designated for only certain kinds of traffic.
* Turning uPnP/NAT-PMP on or off.
* Configuring software updates on Windows and Mac platforms.
* Defining trusted paths (the old trusted paths file is now deprecated)
* Setting the ZeroTier main port so it doesn't have to be changed on the command line, which is very inconvenient in many cases.
A good software update system for Windows and Mac clients has been a missing feature in previous versions. It does exist but we've been shy about using it so far due to its fragility in some environments.
We've greatly improved this mechanism in 1.2.0. Not only does it now do a better job of actually invoking the update, but it also transfers updates in-band using the ZeroTier protocol. This means it can work in environments that do not allows http/https traffic or that force it through proxies. There's also now an update channel setting: `beta` or `release` (the default).
Software updates are authenticated three ways:
1. ZeroTier's own signing key is used to sign all updates and this signature is checked prior to installation. ZeroTier, Inc.'s signatures are performed on an air-gapped machine.
2. Updates for Mac and Windows are signed using Apple and Microsoft (DigiCert EV) keys and will not install unless these signatures are also valid.
3. The new in-band update mechanism also authenticates the source of the update via ZeroTier's built-in security features. This provides transport security, while 1 and 2 provide security of the update at rest.
Updates are now configurable via `local.conf`. There are three options: `disable`, `download`, and `apply`. The third (apply) is the default for official builds on Windows and Mac, making updates happen silently and automatically as they do for popular browsers like Chrome and Firefox. Updates are disabled by default on Linux and other Unix-type systems as these are typically updated through package managers.
Version 1.2.0 is now aware of the link quality of direct paths with other 1.2.0 nodes. This information isn't used yet but is visible through the JSON API. (Quality always shows as 100% with pre-1.2.0 nodes.) Quality is measured passively with no additional overhead using a counter based packet loss detection algorithm.
This information is visible from the command line via `listpeers`:
200 listpeers XXXXXXXXXX 199.XXX.XXX.XXX/9993;10574;15250;1.00 48 1.2.0 LEAF
200 listpeers XXXXXXXXXX 195.XXX.XXX.XXX/45584;467;7608;0.44 290 1.2.0 LEAF
The first peer's path is at 100% (1.00), while the second peer's path is suffering quite a bit of packet loss (0.44).
Link quality awareness is a precursor to intelligent multi-path and QoS support, which will in future versions bring us to feature parity with SD-WAN products like Cisco iWAN.
Version 1.2.0 adds anti-DOS (denial of service) rate limits and other hardening for improved resiliency against a number of denial of service attack scenarios.
It also adds a mechanism for instantaneous credential revocation. This can be used to revoke certificates of membership instantly to kick a node off a network (for private networks) and also to revoke capabilities and tags. The new controller sends revocations by default when a peer is de-authorized.
Revocations propagate using a "rumor mill" peer to peer algorithm. This means that a controller need only successfully send a revocation to at least one member of a network with connections to other active members. At this point the revocation will flood through the network peer to peer very quickly. This helps make revocations more robust in the face of poor connectivity with the controller or attempts to incapacitate the controller with denial of service attacks, as well as making revocations faster on huge networks.
The Mac has a whole new UI built natively in Objective-C. It provides a pulldown similar in appearance and operation to the Mac WiFi task bar menu.
The Windows UI has also been improved and now provides a task bar icon that can be right-clicked to manage networks. Both now expose managed route and IP permissions, allowing nodes to easily opt in to full tunnel operation if you have a router configured on your network.
A special kind of public network called an ad-hoc network may be accessed by joining a network ID with the format:
ffSSSSEEEE000000
| | | |
| | | Reserved for future use, must be 0
| | End of port range (hex)
| Start of port range (hex)
Reserved ZeroTier address prefix indicating a controller-less network
Ad-hoc networks are public (no access control) networks that have no network controller. Instead their configuration and other credentials are generated locally. Ad-hoc networks permit only IPv6 UDP and TCP unicast traffic (no multicast or broadcast) using 6plane format NDP-emulated IPv6 addresses. In addition an ad-hoc network ID encodes an IP port range. UDP packets and TCP SYN (connection open) packets are only allowed to desintation ports within the encoded range.
For example `ff00160016000000` is an ad-hoc network allowing only SSH, while `ff0000ffff000000` is an ad-hoc network allowing any UDP or TCP port.
Keep in mind that these networks are public and anyone in the entire world can join them. Care must be taken to avoid exposing vulnerable services or sharing unwanted files or other resources.
The network controller has been largely rewritten to use a simple in-filesystem JSON data store in place of SQLite, and it is now included by default in all Windows, Mac, Linux, and BSD builds. This means any desktop or server node running ZeroTier One can now be a controller with no recompilation needed.
If you have data in an old SQLite3 controller we've included a NodeJS script in `controller/migrate-sqlite` to migrate data to the new format. If you don't migrate, members will start getting `NOT_FOUND` when they attempt to query for updates.
* **The Windows HyperV 100% CPU bug is FINALLY DEAD**: This long-running problem turns out to have been an issue with Windows itself, but one we were triggering by placing invalid data into the Windows registry. Microsoft is aware of the issue but we've also fixed the triggering problem on our side. ZeroTier should now co-exist quite well with HyperV and should now be able to be bridged with a HyperV virtual switch.
* **Segmenation faults on musl-libc based Linux systems**: Alpine Linux and some embedded Linux systems that use musl libc (a minimal libc) experienced segmentation faults. These were due to a smaller default stack size. A work-around that sets the stack size for new threads has been added.
* **Windows firewall blocks local JSON API**: On some Windows systems the firewall likes to block 127.0.0.1:9993 for mysterious reasons. This is now fixed in the installer via the addition of another firewall exemption rule.
* **UI crash on embedded Windows due to missing fonts**: The MSI installer now ships fonts and will install them if they are not present, so this should be fixed.
* **Improved dead path detection**: ZeroTier is now more aggressive about expiring paths that do not seem to be active. If a path seems marginal it is re-confirmed before re-use.
* **Minor performance improvements**: We've reduced unnecessary memcpy's and made a few other performance improvements in the core.
* **Linux static binaries**: For our official packages (the ones in the download.zerotier.com apt and yum repositories) we now build Linux binaries with static linking. Hopefully this will stop all the bug reports relating to library inconsistencies, as well as allowing our deb packages to run on a wider variety of Debian-based distributions. (There are far too many of these to support officially!) The overhead for this is very small, especially since we built our static versions against musl-libc. Distribution maintainers are of course free to build dynamically linked versions for inclusion into distributions; this only affects our official binaries.
Merge branch 'master' of github.com:zerotier/ZeroTierOne
The largest new feature in 1.2.0, and the product of many months of work, is our advanced network rules engine. With this release we achieve traffic control, security monitoring, and micro-segmentation capability on par with many enterprise SDN solutions designed for use in advanced data centers and corporate networks.
Rules allow you to filter packets on your network and vector traffic to security observers. Security observation can be performed in-band using REDIRECT or out of band using TEE.
Tags and capabilites provide advanced methods for implementing fine grained permission structures and micro-segmentation schemes without bloating the size and complexity of your rules table.
See the [rules engine announcement blog post](https://www.zerotier.com/blog/?p=927) for an in-depth discussion of theory and implementation. The [manual](https://www.zerotier.com/manual.shtml) contains detailed information on rule, tag, and capability use, and the `rule-compiler/` subfolder of the ZeroTier source tree contains a JavaScript function to compile rules in our human-readable rule definition language into rules suitable for import into a network controller. (ZeroTier Central uses this same script to compile rules on [my.zerotier.com](https://my.zerotier.com/).)
It's now possible to create your own root servers and add them to the root server pool on your nodes. This is done by creating what's called a "moon," which is a signed enumeration of root servers and their stable points on the network. Refer to the [manual](https://www.zerotier.com/manual.shtml) for instructions.
Federated roots achieve a number of things:
* You can deploy your own infrastructure to reduce dependency on ours.
* You can deploy roots *inside your LAN* to ensure that network connectivity inside your facility still works if the Internet goes down. This is the first step toward making ZeroTier viable as an in-house SDN solution.
* Roots can be deployed inside national boundaries for countries with data residency laws or "great firewalls." (As of 1.2.0 there is still no way to force all traffic to use these roots, but that will be easy to do in a later version.)
* Last but not least this makes ZeroTier somewhat less centralized by eliminating any hard dependency on ZeroTier, Inc.'s infrastructure.
Our roots will of course remain and continue to provide zero-configuration instant-on deployment, a secure global authority for identities, and free traffic relaying for those who can't establish peer to peer connections.
An element of our design philosophy is "features are bugs." This isn't an absolute dogma but more of a guiding principle. We try as hard as we can to avoid adding features, especially "knobs" that must be tweaked by a user.
As of 1.2.0 we've decided that certain knobs are unavoidable, and so there is now a `local.conf` file that can be used to configure them. See the ZeroTier One documentation for these. They include:
* Blacklisting interfaces you want to make sure ZeroTier doesn't use for network traffic, such as VPNs, slow links, or backplanes designated for only certain kinds of traffic.
* Turning uPnP/NAT-PMP on or off.
* Configuring software updates on Windows and Mac platforms.
* Defining trusted paths (the old trusted paths file is now deprecated)
* Setting the ZeroTier main port so it doesn't have to be changed on the command line, which is very inconvenient in many cases.
A good software update system for Windows and Mac clients has been a missing feature in previous versions. It does exist but we've been shy about using it so far due to its fragility in some environments.
We've greatly improved this mechanism in 1.2.0. Not only does it now do a better job of actually invoking the update, but it also transfers updates in-band using the ZeroTier protocol. This means it can work in environments that do not allows http/https traffic or that force it through proxies. There's also now an update channel setting: `beta` or `release` (the default).
Software updates are authenticated three ways:
1. ZeroTier's own signing key is used to sign all updates and this signature is checked prior to installation. ZeroTier, Inc.'s signatures are performed on an air-gapped machine.
2. Updates for Mac and Windows are signed using Apple and Microsoft (DigiCert EV) keys and will not install unless these signatures are also valid.
3. The new in-band update mechanism also authenticates the source of the update via ZeroTier's built-in security features. This provides transport security, while 1 and 2 provide security of the update at rest.
Updates are now configurable via `local.conf`. There are three options: `disable`, `download`, and `apply`. The third (apply) is the default for official builds on Windows and Mac, making updates happen silently and automatically as they do for popular browsers like Chrome and Firefox. Updates are disabled by default on Linux and other Unix-type systems as these are typically updated through package managers.
Version 1.2.0 is now aware of the link quality of direct paths with other 1.2.0 nodes. This information isn't used yet but is visible through the JSON API. (Quality always shows as 100% with pre-1.2.0 nodes.) Quality is measured passively with no additional overhead using a counter based packet loss detection algorithm.
This information is visible from the command line via `listpeers`:
200 listpeers XXXXXXXXXX 199.XXX.XXX.XXX/9993;10574;15250;1.00 48 1.2.0 LEAF
200 listpeers XXXXXXXXXX 195.XXX.XXX.XXX/45584;467;7608;0.44 290 1.2.0 LEAF
The first peer's path is at 100% (1.00), while the second peer's path is suffering quite a bit of packet loss (0.44).
Link quality awareness is a precursor to intelligent multi-path and QoS support, which will in future versions bring us to feature parity with SD-WAN products like Cisco iWAN.
Version 1.2.0 adds anti-DOS (denial of service) rate limits and other hardening for improved resiliency against a number of denial of service attack scenarios.
It also adds a mechanism for instantaneous credential revocation. This can be used to revoke certificates of membership instantly to kick a node off a network (for private networks) and also to revoke capabilities and tags. The new controller sends revocations by default when a peer is de-authorized.
Revocations propagate using a "rumor mill" peer to peer algorithm. This means that a controller need only successfully send a revocation to at least one member of a network with connections to other active members. At this point the revocation will flood through the network peer to peer very quickly. This helps make revocations more robust in the face of poor connectivity with the controller or attempts to incapacitate the controller with denial of service attacks, as well as making revocations faster on huge networks.
The Mac has a whole new UI built natively in Objective-C. It provides a pulldown similar in appearance and operation to the Mac WiFi task bar menu.
The Windows UI has also been improved and now provides a task bar icon that can be right-clicked to manage networks. Both now expose managed route and IP permissions, allowing nodes to easily opt in to full tunnel operation if you have a router configured on your network.

Move setting _initialized = true until after WindowsEthernetTap::threadMain() has actually created and brought up the adapter. Also in OneService::nodeVirtualNetworkConfigFunction(), wait up to 5 seconds for WindowsEthernatTap::isInitialized() to return true before attempting to configure the interface and managed routes. Without this, the adapter doesnt actually exist yet when trying to add routes
Also, dont add the prefix length to the IP addresses in there.
Appears to fix Github Issue #357. Still waiting on some info from Microsoft for confirmation of a few things.
WindowsEthernetTap was storing the MTU for the ZeroTier Adapter as a
DWORD. When changing the value from the network adapter settings UI, it
was stored as a string. Updated the call when creating the adapter to
store it as a string as windows expects.
- ZT will only drop root privileges if zerotier-one user exists. It is created by
Debian postinst script - in other cases the user has to be created by administrator.
- Linux >=4.3 with ambient capabilities is required, otherwise ZT will silently
- "-U" option now also disables privileges dropping
Version 1.1.10 is a minor bug fix release. It fixes the following two issues:
* Routes are no longer added 'via' IP addresses of the current node's ZT interface.
* IPv6 default route is now fixed on Mac.
* IP addresses are now deleted before new ones are added to allow changes to netmask
on Mac and some other platforms.
This version also quietly introduces a feature called trusted paths. We'll be
documenting this in our community section soon. This is an experimental feature
for in-LAN SDN use.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.
