Limit entropy count for rng devices

Neil Horman — Thu, 16 Apr 2015 14:46:19 -0000

Hey, I received a request the other day from here:
https://bugzilla.redhat.com/show_bug.cgi?id=1211406

Indicating that the entropy_count was always assumed to be 8-bits for input random data from rngd. While its impossible to tell without introspection of the source device how much entropy a data stream has, it seems like some people might want to be more conservative in that estimate, so I created this patch, which allows a user to specify the amount of entropy in a given source.

#135 [rng-tools] rngd daemon waits to respond to SIGTERM

Leonardo Chiquitto — Thu, 18 Sep 2014 15:19:49 -0000

When running as a daemon, a signal handler is installed to catch SIGINT/SIGTERM. This handler sets a flag that's tested in the main loop. However, rngd loops in update_kernel_random(), where the flag is not tested.

The patch attached fixes this problem.

[rng-tools] outdated defaults

Disconnect — Thu, 24 Oct 2013 14:40:38 -0000

While https://www.kernel.org/doc/Documentation/hw_random.txt shows /dev/hw_random as the default name, https://git.kernel.org/cgit/linux/kernel/git/bwh/linux-3.2.y.git/tree/drivers/char/hw_random/core.c#n180 uses /dev/hwrng. (It looks like that changed in 2009: https://git.kernel.org/cgit/linux/kernel/git/bwh/linux-3.2.y.git/commit/drivers/char/hw_random/core.c?id=d405640539555b601e52f7d18f1f0b1345d18bf5 )

The rng-tools default should probably match the upstream.

[rng-tools] Allows user to point HRNGDEVICE to /dev/random or /dev/urandom

Aaron Peschel — Thu, 16 May 2013 23:06:41 -0000

rng-tools allows the user to point HRNGDEVICE to /dev/random/ or /dev/urandom, creating a very questionable RNG loop. There is no documentation explicitly telling users that this is a bad idea, and there are examples of people suggesting this practice with no indication of its badness.

http://www.howtoforge.com/helping-the-random-number-generator-to-gain-enough-entropy-with-rng-tools-debian-lenny
http://www.chrissearle.org/blog/technical/increase_entropy_26_kernel_linux_box

Not sure if it would be best to explicitly block /dev/*random as the rng-tools input, or issue a warning of some kind, or something else entirely.

[rng-tools] rngd daemon waits to respond to SIGTERM

Chris Mayo — Sat, 25 Aug 2012 14:57:44 -0000

rng-tools-4 using Ivy Bridge (i3770) DRNG on Gentoo Linux, kernel gentoo-sources-3.5.2

- rngd running as daemon
1) killall rngd
- rngd still running
2) cat /dev/random > /dev/null
- rngd not running

rngd running in the foreground will stop immediately on SIGTERM
and can stop rngd daemon immediately with:
killall -s SIGALRM rngd

ethtool -p and sudo

Joe Kuan — Wed, 09 Sep 2009 15:34:30 -0000

If I run "sudo ethtool -p eth0 &", it runs fine. However, the terminal hangs if I launch another 'sudo' command. Regardless of what sudo command is, even if I do 'sudo abc', it just hangs.

The terminal session can only be resumed if I launch 'killall ethtool' from another root shell, not "sudo killall ethtool", this will hang again.

I am not sure this is sudo or ethtool problem.

My current system is Ubuntu 8.04 LTS running ethtool ver 6.

Intel 10GE CX4: link type FIBRE?

Andras HORVATH — Mon, 24 Nov 2008 14:03:39 -0000

Hi,

The link type on this card is mis-identified as FIBRE. I don't know if this is because of the driver or ethtool (although I'm using the current driver set from Intel directly).

I'm willing to test if you have an idea what to test :)

Current (2008-NOV-24) GIT HEAD gives the following:

root@lxfsrc1403:/usr/src/ethtool# ./ethtool eth2
Settings for eth2:
Supported ports: [ FIBRE ]
Supported link modes: 10000baseT/Full
Supports auto-negotiation: No
Advertised link modes: 10000baseT/Full
Advertised auto-negotiation: No
Speed: 10000Mb/s

PHYAD: 0
Transceiver: external
Auto-negotiation: off
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000007 (7)
Link detected: yes

whereas the card is connected (and only has) copper CX4 interfaces.
This is with a new (current) Intel driver plus a recompiled RHEL5.

I don't know if the card should support autoneg or not, or if any other non-trivial (to me) data are wrong in the output above. The link speed is 10gig at the moment, so that's okay.

root@lxfsrc1403:/usr/src/ethtool# ./ethtool -i eth2

Ethtool give the following output:

[root@host ~]# ethtool eth0
Settings for eth0:
No data available

How can I get Wake on Lan working with ethtool?

Thanks a lot!

ethtool -E eth0 magic 0x1234 offset 0x15 value 0x7d
Unfortunatelly I was not taking care about checksums.

I tried without success:
setpci -v -G -s 3 VENDOR_ID=8086 DEVICE_ID=1229
output:
Trying method 1......using /sys/bus/pci...OK
Decided to use Linux-sysfs

new flash BIOS update

What could be next? any idea?

ethtool dump_supported missing 10GBase-T

Thu, 20 Sep 2007 14:46:55 -0000

dump_supported() in ethtool doesn't check for SUPPORTED_10000baseT_Full. The output for a 10GBase-T (only) NIC is:

Settings for eth2:
Supported ports: [ TP ]
Supported link modes:
Supports auto-negotiation: No
Advertised link modes: 10000baseT/Full
Advertised auto-negotiation: No
Speed: 10000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: off
Current message level: 0x00000001 (1)
Link detected: no

It should be:

Settings for eth2:
