The Click modular router: fast modular packet processing and analysis

The Click Modular Router

Click is a modular router toolkit. To use it you'll need to know how to compile and install the software, how to write router configurations, and how to write new elements. Our ACM Transactions on Computer Systems paper will give you a feeling for what Click can do. Using the optimization tools under CLICKDIR/tools, you can get even better performance than that paper describes.

Documentation

The INSTALL.md file in this directory contains installation instructions. User documentation is in the doc subdirectory, which contains manual pages for the Click language, the Linux kernel module, and several tools; it also has a script that generates manual pages for many of the elements distributed in this package. To install these manual pages so you can read them, follow the INSTALL.md instructions, but make install-man instead of make install.

Running a Click Router

Before playing with a Click router, you should get familiar with the Click configuration language. You use this to tell Click how to process packets. The language describes a graph of “elements,” or packet processing modules. See the doc/click.5 manual page for a detailed description, or check the conf directory for some simple examples.

Click can be compiled as a user-level program or as a kernel module for Linux. Either driver can receive and send packets; the kernel module directly interacts with device drivers, while the user-level driver uses packet sockets (on Linux) or the pcap library (everywhere else).

User-Level Program

Run the user-level program by giving it the name of a configuration file: click CONFIGFILE.

Linux Kernel Module

See the doc/click.o.8 manual page for a detailed description. To summarize, install a configuration by running click-install CONFIGFILE. This will also install the kernel module if necessary and report any errors to standard error. (You must run make install before click-install will work.)

NS-3 Simulator

See INSTALL.md for more information. Further information on NS-3 and Click is available in the NS-3 manual.

NS-2 Simulator

See INSTALL.md for more information. Once a Click-enabled version of NS-2 is installed, the 'ns' command is able to run Click scripts as part of a normal NS-2 simulation.

DPDK

Click’s user-level driver supports DPDK. Before running in DPDK mode, the DPDK must be set up properly as per the DPDK documentation. This mainly involves setting up huge pages and binding some NIC to the DPDK userspace driver. E.g., to set up huge pages:

echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
mkdir -p /mnt/huge
mount -t hugetlbfs nodev /mnt/huge

On x86_64 you might achieve better performances with 1G huge pages, which must be enabled through the kernel cmdline.

Intel NICs use entierly userspace drivers and needs to be bound to DPDK. Eg., to bind eth0 to DPDK:

modprobe uio_pci_generic
dpdk/tools/dpdk_nic_bind.py --bind=uio_pci_generic eth0

Refer to the DPDK documentation for more details about huge pages and binding devices.

Unlike most other DPDK applications, you have to pass DPDK EAL arguments between --dpdk and --, then pass Click arguments. As the DPDK EAL will handle thread management instead of Click, Click's -j/--threads argument will be disabled when --dpdk is active. You should give at least the following two EAL arguments for best practice. This is required with older versions of DPDK, even if running on a single core:

• -c COREMASK: hexadecimal bitmask of cores to run on
• -n NUM: number of memory channels

If -c or -l is not provided, DPDK will use all available cores.

A sample command to run a click configuration on 4 cores on a computer with 4 memory channels and listen for control connections on TCP port 8080 would be:

click --dpdk -c 0xf -n 4 -- -p 8080 configfile

If Click is launched without --dpdk, it will run in normal userlevel mode without involving DPDK EAL, meaning that any DPDK element will not work.

Configurations

Some sample configurations are included in the conf directory, including a Perl script that generated the IP router configurations used in our TOCS paper (conf/make-ip-conf.pl) and a set of patterns for the click-xform pattern optimizer (conf/ip.clickpat).

click's Issues

click on netmap

Hi, guys,
Tonight, i was working on running click-netmap. This is my problem when i run my configuration.

Below is my configuration code:

Below is the steps which i install netmap and click-netmap:

Issue with missing PCAP magic

I've been generating a PCAP trace with libpcap 1.5.3 and reading it as follows to sort it:

ipsumdump -r - --collate -w - < trace.pcap > sorted.pcap

It gives me a magic error:

config:1: While initializing ‘src0 :: FromDump(<stdin>)’:
<stdin>:   not a tcpdump file (bad magic number)

Looking the beginning of my generated trace with xxd, I get this:

0000000: 4d3c b2a1 0200 0400 0000 0000 0000 0000  M<..............
0000010: ffff 0000 6500 0000 30a5 044b 3085 3812  ....e...0..K0.8.

So the magic number is 0xa1b23c4d. In fakepcap.hh, you define:

#define FAKE_PCAP_MAGIC             0xA1B2C3D4
#define FAKE_MODIFIED_PCAP_MAGIC    0xA1B2CD34

If the magic does not equal either value, ipsumdump produces the above error. According to the wireshark wiki, the magic I get should also be okay:

[..] the writing application writes 0xa1b23c4d, with the two nibbles of the two lower-order bytes swapped, and the reading application will read either 0xa1b23c4d (identical) or 0x4d3cb2a1 (swapped).

This suggest to me that you should add another constant to allow the version with the lower-order bytes swapped, maybe FAKE_PCAP_MAGIC_SWAPPED. I'm happy to issue a pull request if you greenlight this change.

Lastest build not detected by NS3

I used the latest build to test for #196. While it does compile and make succeeds when cd'ing back into the main ns3 directory to configure it does not detect that the click library has been installed.

I went back to the lastest revision I could find that built and was detected properly with: 392b1f6

Ran the old build, which was detected, then ran the same commands for the latest build which fails to be detected by ns3.

Clicky: "Connection error: Broken pipe"

When I use Clicky (on one of the sample .click files, for instance), the following happens: when the configuration is running, and I try to open the element sidebar or switch it to a different component or basically do anything that changes its visual structure, I get the error "Connection error: Broken pipe" and the configuration stops running.

I'm using Debian jessie, 64 bit.

an user-space click-openflow element

Hi guys:
Recently,Im using an user-space click-openflow element which was publicing on "https://nm.gist.ac.kr/twiki/bin/view/Main/OpenFlowInClick_Internal". But in the source code, I can't find any tutorial. And I don't know how to use this element. Can anybody help me?
Thank you ver much!
Sincerely,
J.L.

Is there a fix available for this issue? The issue is because of enums wrapped in structs are not visible in global scope (in C++).

Additionally, this header 'context_tracking_state.h' was added in August 2013 in the kernel source.

Running maz-nat in userspace

Hi Eddie,
I need to run maz-nat in userspace and I'm having a problem with TCP. Yes, I know kernel space gives much much better performance. But we are in the process of integrating Click with another project and we must run Click in userspce.

Using the same configuration file in Click repo, I could use it in kernelspace with full link BW. When I switched to userspace, I had to modify the configuration file by changing ToHost element to ToHost(tap0) since the first one only works in linuxmode. With theses changes, I can only test iperf in UDP between two end hosts and of course click running maz-nat in a machine resides in the middle.

Now, the only way I could make the two end hosts reach each other with tcp is by disabling ARP in the interfaces in the machine running click. When ARP is off, Click seems to respond to arp queries. I wrote a simple tcp client/server program and was able to connect them and send some packets between them (through click-nat of course).

The main problem is when I want to run tcp iperf. When the connection is established between the two ends, Click shows this error "CheckIPHeader@37: IP header check failed: bad IP length".
After the test is done. Both ends report BW with 70Kbit. Which is about one packet.
Looking at Wireshark at the machine running NAT, it seems that Client keep retransmitting a packet over and over.

I am guessing the problem is related to ARP since it is the only thing changed in config file and also the tcp handshake since click shows the error above.

Any suggestions?

Thanks alot

Click on linux-3.16.7

Dear all,

I would like to run click (kernel module) on an APU (pc engines) with voyage 0.10.0.
Voyage 0.10.0 comes with kernel 3.16.7 but I was unable to build click against this kernel due to a kernel header errors related to linuxmodule/fixincludes.pl. (first error in config.log unable to find kconfig.h)
I fixed some of the errors by adding symbolic links in the linux include dir.
After three attempts I've got a bad feeling about my approach...
Click perfectly builds against 3.13.

Does somebody has more insights of what might have changed in the kernel?

Thanks,

Bart

Errors and warnings not being printed when using live_reconfigure?

Hi, I'm currently adding some live_reconfigure functionality to the RoundRobinIPMapper module, and noticed that errors and warnings are not being printed to console when I do a live_reconfigure. Is this expected behaviour? I've looked through the docs for ErrorHandler and live_reconfigure, and haven't found the answer. In the meanwhile, I've just replaced the error warnings with click_chatter functions.

My changes to RoundRobinIPMapper are fairly simple, I've just added a new live_reconfigure function that pops off the patterns from the previous config.

Weird memset argument in RangeIPLookup::flush_table()

In elements/ip/rangeiplookup.cc, it says

void
RangeIPLookup::flush_table()
{
    _helper.flush();
    memset(_range_base, 0, sizeof(_range_base));
    memset(_range_len, 0, sizeof(_range_len));
    memset(_range_t, 0, sizeof(_range_t));
}

Since those members are pointers, memset is clearing something the size of the pointer, not an element in the underlying array. Is this the intention? or should the code be

void
RangeIPLookup::flush_table()
{
    _helper.flush();
    memset(_range_base, 0, sizeof(*_range_base));
    memset(_range_len, 0, sizeof(*_range_len));
    memset(_range_t, 0, sizeof(*_range_t));
}

or

void
RangeIPLookup::flush_table()
{
    _helper.flush();
    memset(_range_base, 0, (1 << KICKSTART_BITS) * sizeof(*_range_base));
    memset(_range_len, 0, (1 << KICKSTART_BITS) * sizeof(*_range_len));
    memset(_range_t, 0, RANGES_MAX * sizeof(*_range_t));
}

BoundedIntArg does not handle types beyond 'int'

uint32_t myval;
uint32_t max_allowed = 100;
if (!BoundedIntArg(0, max_allowed).parse(mystr, myval))
    return errh->error("bad number");

gives compiler warnings, because BoundedIntArg always uses int to store the lower/upper bounds, and I suspect that it would have issues with very large unsigned bounds.

Compile error on ARM

When compiling for an ARM target using the OpenWRT toolchain I get the following compile error. Seems to be linked to the static_assert call made in the Timer constructor.

../lib/timer.cc: In constructor 'Timer::Timer()':
../lib/timer.cc:198:5: error: duplicate case value
../lib/timer.cc:198:5: error: previously used here

how to get payload of the packet?

Below is my packet:

| MAC header(14 bytes) | IP header(20 bytes) | TCP header(20 bytes) | Options(12 bytes) | PAYLOAD |

configure: making C++-safe versions of Linux kernel headers (may take a while)

configure: error:

Your Linux kernel header files cause errors when included by a C++ program.

Click modifies the Linux kernel's header files to make them work with
C++, using the program 'linuxmodule/fixincludes.pl'. It looks like
your kernel header files have features that 'linuxmodule/fixincludes.pl'
doesn't know how to fix. You can report this error to us on the Click
mailing list, or, even better, try to fix the error. See the config.log
file for more information on the error.

NULL dereference on click unload

On an SMP platform, I sometimes see a NULL dereference after clearing out the click config my writing "" to /click/config. The backtrace is below and the issue appears to occur in Task::add_pending() when thread->_pending_lock becomes invalid.

Multiple it_present fields in radiotap header

the RadioTapDecap module has a problem if the Wi-Fi driver is using multiple it_present fields.

If the Wi-Fi card has multiple antennas there may be several it_present fields. I recognized it by looking in a wireshark trace. I had for example four RSSI fields in the radiotap header.

The current RadioTapDecap module is assuming that there is just one and therefore accesses a wrong position in the radiotap header to read e.g. the signal strength.

Can element1 pass an parameter to element2??

Crash in kernel mode with 10 Gbps IXGBE driver on amd64

Hello,

I tried to use Click in linuxmodule mode for various kernels between 2.6.32 and 3.16 with 10 Gbps IXGBE cards, and it always crashes with a page fault in ixgbe_xmit_frame_ring() after sending a few packets (only 144 in my last test with only 2 packets per second). Our server is an Intel-based amd64 platform, using Debian jessie (except for the 3.16 kernel try, which used sid).

The relevant part of the kernel panic stack trace is as follows:

panic
oops_end
no_context
__do_page_fault
KernelErrorHandler::buffer_store
KernelErrorHandler::log_line
click_lfree
KernelErrorHandler::emit
page_fault
ixgbe_xmit_frame_ring
ToDevice::queue_packet
ToDevice::run_task

Investigating ToDevice::queue_packet() with the help of added click_chatter() and early return, I think the problem occurs in the call to dev->netdev_ops->ndo_start_xmit(skb1, dev).

I can reproduce the problem even with the trimmed-down configuration that follows:

// Echoes back any packet arriving on eth2 without any processing
FromDevice(eth2, PROMISC 1) -> Queue() -> ToDevice(eth2)

For completeness, I had to take the following steps to compile kernel-mode Click (most of them suggested in the other issues).

• Merge /usr/src/linux-headers-VERSION-amd64 and /usr/src/linux-headers-VERSION-common.
• Copy /boot/config-VERSION and /boot/Sytem.map-VERSION to the source directory as .config and System.map, respectively.
• Symlink /usr/src/linux-headers-VERSION-merged/include/generated/autoconf.h to /usr/src/linux-headers-VERSION-merged/include/linux/autoconf.h.
• Add an #undef DEPRECATED in include/click/handler.hh (as it is defined in linux/printk.h, which is apparently included by handler.hh).
• ./configure --disable-userlevel --enable-linux-module --with-linux=/usr/src/linux-headers-VERSION-merged (I tried first with other options like multithread but the problem also occurs with this simpler configuration).
• Fix minor headers issues depending on kernel version.

ToDevice calls Element::pull, which might block, inside the tx_lock spinlock

This can lead to deadlock. I noticed this on a lock-checking kernel with driver preemption enabled, but it can still happen with preempt disabled (since in_atomic is wrong in that config unless you specifically disable_preempt, confusing the lock-checker). In my setup, a custom Element schedules a timer in the pull path, which should be allowed but which also acquires a mutex in order to update the timer set. It doesn't need to be that complicated though; any pull path from ToDevice that calls a sleepy kmalloc can deadlock.

Either the tx_lock needs to be unlocked and relocked around Element::pull or we need to pre-fill a deque with burst packets and then attempt to drain that inside the tx_lock. The former solution is messy with the current code and the latter adds an extra layer of buffering.

We do currently buffer up to one packet but under ideal circumstances the driver will let us know it is about to be busy before we try to pull that packet.

I talked to Eddie and he prefers the pre-filled-deque solution, so that's what I'm going to work on. This is mostly for record keeping.

Will Clicky be porting to more platforms?

Do you believe that the following is useful in the future? Thanks!

I am getting the following error during the ./configure for clicky.

configure: error: Package requirements (glib-2.0 >= 2.43.0 atk >= 2.12.0 pango >= 1.36.7 cairo >= 1.12.0 cairo-gobject >= 1.12.0 gdk-pixbuf-2.0 >= 2.30.0) were not met:

What should I do?

ToUserDevice+FromUserDevice unsafe across /click/config changes

With the following program, slow_read,

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

int
main(int, char*[]) {
  char c;
  while (1 == read(STDIN_FILENO, &c, sizeof c)) {
    if (write(STDOUT_FILENO, &c, sizeof c) < 0)
      return EXIT_FAILURE;
    sleep(1);
  }
  return EXIT_SUCCESS;
}

install the /click/config

InfiniteSource(LIMIT -1, LENGTH 1, ACTIVE true)
-> ToUserDevice(0, ENCAP none);

and then

mknod /dev/click0 c 241 0
slow_read < /dev/click0 &
sleep 5
echo "" > /click/config

and watch the kernel crashes.

The issue is that the methods of ToUserDevice are not synchronized with the click config in any way, so while they are using elem it might disappear out from under them. It seems like clickfs might need to export the read versions of lock_config and unlock_config in order to prevent this from happening while elem is live.

I can implement that solution @kohler, but I wanted to get your take first. It also is not clear to me whether the router should be blocked + unblocked as well.

Hang on unspecified input to top-level connection

This showed up for me originally when I mistakenly added an extra semicolon to a top-level bit of click-config, like so:

some_element;
-> some_other_element;
....
Script(...write stop);

A minimal way to reproduce the issue is:

$CLICK_CHECKOUT/userlevel/click -e "-> Null; Script(print \"script_started\", write stop)"

In both cases, the click process seems to be stuck in a loop (it shows up in top as taking 100% CPU, but reasonable amounts of memory (in the minimal version, about 5K)), and active Script elements never start ("script_started" is not printed).

Omitting only the element after the arrow (Null -> ;) gives a syntax error, as expected; omitting both has the same effect as omitting only the first (hangs).

linux/preempt.h undefine preempt_enable_no_resched since 3.14

Hi all,

Since kernel 3.14, "preempt_enable_no_resched" is undefined in linux/preempt.h to prevent modules from playing with preemption. But "preempt_enable_no_resched()" is called in lib/master.cc .

I do not understand fixlinuxmodules.pl enough, but these undefine should probably be removed by that script...

Also, the problem about DEPRECATED mentioned in #136 is still there.

Thanks

Low limit on SNAPLEN

The size limit on _snaplen in elements/userlevel/fromdevice.cc (line 108) seems low (8190) and inconsistent with pcap's recommended limit (65535). I consistently encountered CheckIPHeader issues because of "bad IP length" as a result of big IP packets that were not being fully captured (even when I set SNAPLEN to the current maximum of 8190). Increasing the limit solved all my issues.

packaging click for debian and derivatives

hi,
i'm packaging click for debian as it will be used in many installations of a project, i builded the packages without problem, but lintian(the linter for debian packages) give me a series of errors for the position of the manpages.
it's nothing that breaks functionality, but it's still an annoying bug during packaging.
i'm packaging the last version from git as for 20130719

Now running lintian...

Unable to use fake ip router program to work

Hi,
I doing my thesis on click with kernel mode and I cannot foward packets within two interfaces (eth0, eth1). I also tried to use Infinite source to generate packets from one source (eth0) to another interface. Nothing works. Whenever I use dmesg I can see packets are created but if I use tcpdump or wireshark like programs I have no packets to my other device (eth1). Do anyone have any suggestions. I tried different sources for tutoring me about Click but I end up at http://www.read.cs.ucla.edu/click/ as root source. I dont understand why there is only a single source for tutorials. Also I request Kohler or developers to make more detailed manual pages. Any programmer new (like me) to kernel programming cannot understand the manual pages.

how to write packets to a temp file and then i can read packets from this temp file?

Hi, guys,

How to write packets to a temp file using c++ standard library and then i can read packets from this temp file?

I use FromDump and ToDump elements, but there is a bus error.

Best regards,
chuanic

Cannot compile click linux module

I am trying to compile the click linux module on ubuntu set up on virtual box

but i am getting the error:

Your Linux kernel header files cause errors when included by a C++ program.

Click modifies the Linux kernel's header files to make them work with
C++, using the program 'linuxmodule/fixincludes.pl'. It looks like
your kernel header files have features that 'linuxmodule/fixincludes.pl'
doesn't know how to fix. You can report this error to us on the Click
mailing list, or, even better, try to fix the error. See the config.log
file for more information on the error.

I tried to run the following command
sudo ./configure --with-linux=/usr/src/linux-headers-3.16.0-30-generic --with-linux-map=/boot/System.map-3.16.0-30-generic --enable-linuxmodule

and based on devious posts I also do ln -s ../generated/autoconf.h inside /usr/src/linux-headers-3.16.0-30-generic/include/linux.

Please help me

caplen annotation ignored in FromDump element for PCAP files

Attempting to replay a PCAP trace in which only the first caplen bytes have been recorded and len contains the actual packet length, generates packets which only have a length of caplen.

It seem that the line
SET_EXTRA_LENGTH_ANNO(p, len - caplen);

in elements/userlevel/fromdump.cc does not have any effect.

Configure script doesn't find Linux headers - Debian Wheezy

Trying to configure Click on the present stable Debian (Wheezy) I get the following error:

=========================================
Can't find include/linux/skbuff.h in /lib/modules/3.2.0-4-686-pae/build.
Are you sure /lib/modules/3.2.0-4-686-pae/build contains Linux kernel source?
=========================================

I assume that the problem is connected with a (not so) recent (2009) change in kernel headers packages in Debian. Symbolic links for the common headers are no longer included in the flavour-specific headers directory. Click configure script tries to find headers in /lib/modules/VERSION/build directory, which links to the the flavour-specific headers directory. However, these headers are located under /lib/modules/VERSION/source. It is shown below.

I've found a similar bug filled against Debian kernel headers, but it was closed as wontfix: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=521515

Basing on the discussion above, I assume that it should be fixed on the Click side rather than Debian. However I am not enough fluent in configure/kbuild/make things to fix it myself.

PrintWifi and 802.11ac

Hi all,

I'am trying to use click on top of an ath10k compliant card in monitor mode.
Wireshark is able to decode (radiotap header) my incoming frames transmitted from a station to an AP (two other devices).
My click script looks like this
FromDevice(wlan1, PROMISC 1) -> RadiotapDecap() -> PrintWifi() -> Discard();

Some parts look ok like tods, data,... but some values like rate, rssi,.. are not being decoded.

2008 | 0Mb + 0/ 0 | data tods
2008 | 0Mb + 0/ 0 | data tods
....

radiotap.h and RadiotapDecap.cc seems to be changed recently.

Can you suggest how I can try to fix this?

Thanks a lot in advance,

Bart

clickfs handler thread safety

On an SMP system, I installed the following click config.

elementclass Idles {
    Idle -> Discard;
    Idle -> Discard;
    // 20x
    Idle -> Discard;
}

Idles;
Idles;
// 20x
Idles;

Then I do

for i in $(seq 1 100) ; do
   md5sum /click/flatconfig & true
done
wait

a few times and I get slab corruption or a panic. I believe that handler_strings is not thread safe and am looking for guidance on possible ways to write a fix.

Question: print value of counter

Sorry if this is an obvious thing, I have read through the examples and documentation with no luck. But how do I print a value of a counter? Is is possible to do any if/else conditions on the counter value, eg. trigger some action when a counter reaches a certain threshold?

click-install not working

Hi everyone,
I have a serious problem which i spent some days to fix. Please help me solve this problem. When i run some file *.click under linuxmodule mode, I got a report:

oneclick@oneclick:~/click/conf$ click-install mazu-nat.click
insmod: error inserting '/usr/local/lib/proclikefs.ko': -1 Operation not permitted
click-install: '/sbin/insmod /usr/local/lib/proclikefs.ko' failed

My ubuntu version is 10.04 (Kernel version: 2.6.32-38-generic). How can I fix this?
I wish all you have a nice day!

Kernel BUG when setting Priority Level in click-install

Hi,
I am encoutering a problem when trying to install a click configuration with click-install and setting a priority level. For example, running "click-install --priority=19 configuration.click" gives me the following error while "click-install configuration.click" goes through with no problems. (Any number, not necessarily 19 gives me an error)

I am not using anything apart from the normal elements, the configuration file is :

define($server 143.205.176.132);
phyint :: FromDevice(wlan0);
EtherClassify :: Classifier (12/0800,-); // 0800 in the 12th-13th byte,means its an IP Frame
EtherClassify[1] -> ToHost(wlan0);
NtwClassify :: IPClassifier($server/32 tcp,-);
NtwClassify[1] -> Unstrip(14) -> ToHost(wlan0);

phyint -> EtherClassify[0] -> Strip(14) //Manual strip of ETHER Header (no Element)
-> CheckIPHeader() -> NtwClassify[0]
-> Unstrip(14) -> ToHost(wlan0);

How do I fix this ?

P.S. : I am actually trying to give my click kernel thread a higher priority to get delay accuracy in DelayUnqueue with less than 50microseconds error.

Userlevel FromDevice with PCAP on Ubuntu does not work

Click team,

Running userlevel Click inside Ubuntu VM and using FromDevice(METHOD PCAP) results in ~99 - 100% packet drops. Using METHOD LINUX works 100%.

Tcpdump on this same VM works fine, so I'm assuming there is an issue on the async IO side.

The issue seems to be only on Ubuntu (tested with 14.04.1 and 14.10 on virtual machine), testing with CentOS using the exact same Click setup and config everything works fine.

Has anyone else experienced this as well?
Any pointers how to debug this further?
Could there be some kernel setting that affects PCAPs async processing on Ubuntu?

Can make click router include c++ standard library?

I want to create an element which can generate an txt file, the c++ code just as below:

Click not compiling on version 12.04

I am trying to install click. This is where it is getting stuck:

Compare two bytes but has "segmentation fault"

Below is my problem, i just want to compare any one bytes in packet with an given bytes.

Can anyone help me find what cause the "segmentation fault"???

Thanks!

Manually adding mappings to iprewriter element?

I've looked over the documentation and it appears that there currently isn't a handler/method to manually write mappings to an iprewriter element. Is this the case, or have I missed something?

I'm interested because I'm currently trying to instantiate click instances with some rewriter mappings pre-installed, but this is proving more difficult than I initially thought. Can anyone point me in the right direction? Thanks.

Replace Click mailing list with Github Issues?

I'd like to propose that Click's Github Issues replace the Click mailing list. Apart from the fact that I (and presumably others) are having major issues subscribing to and staying on the Click librelist, as it keeps dropping me off the list for some reason, Github Issues just seems like a more modern approach.

Also I see some people are still using the old mailing list, been trying to forward to librelist but again I find it impossible to stay on the list.

What are your feelings around this?

Can Click in userspace handle large TCP packets?

This is related to my previous issue with running maz-nat config file in userspace. Since we believe the problem is more related to Click itself not maz config file, I am decided to open a new issue for it.

As mentioned before, we are interested on running maz_nat in user space. We made some changes as shown below to switch from linuxmode to usermode. We can run tcp connection through Click NAT and stream small packets. I cleaned up the ARP handling and I can see that Click successfully responses to ARP guiries with the right MAC address.

We believe the problem raises when it comes to stream packers larger than 400 Bytes through Click (we tested with iperf, netperf, and i-dtg). Click in userspace seems to have a bug/unable to handle packets above 400 bytes and misses up checksum and IP header check. Resulting with packets have actual length that is different than what its stated in the header, thus resulting Click to drop the packets when its checks IP header and produce the previous error mentioned "CheckIPHeader@37: IP header check failed: bad IP length".

We tried to change the behavior to not drop the packets even if the checksome failed. But ToDevice element did not like the packet when it arrived to it and produced "Message too long" error.

Please advise,

Murad

Userlevel multithreading support for hotswap

Currently hotswap in multithread userlevel Click is not supported. After the hotswap config only the first thread runs. See http://librelist.com/browser/click/2014/10/3/userlevel-hotswap-with-multithreading/ post for more info.

To replicate:

click -j2 -R -p 41900 -e "s1::Script(print 'A'); s2::Script(print 'B'); StaticThreadSched(s1 0, s2 1);" &
echo "write hotconfig s1::Script(print 'A'); s2::Script(print 'B'); StaticThreadSched(s1 0, s2 1);" | telnet localhost 41900
