ae7dbca783 stratum: parse_notify(): Don't die on malformed bbversion/prev_hash/nbit/ntime. 
Might have introduced a memory leak, don't have time to check. :(

Should the other hex2bin()'s be checked?

Thanks to Mick Ayzenberg <mick.dejavusecurity.com> for finding this.

cab6e28b12 stratum: parse_reconnect(): treat pool-sent URL as untrusted. 
Thanks to Mick Ayzenberg <mick@dejavusecurity.com> for reminding
that this existed and highlighting the offender.

Also to Luke-jr for actually fixing this in bfgminer. :D

a fallback.

1f7b7ef26e stratum: move log warning under opt_disable_client_reconnect clause. 2014-03-24 15:25:31 +02:00
Martin Danielsen
01b3f70b63 A new --no-client-reconnect command that disables the 'client.reconnect' function. 
It looks like there's an exploit that abuses said command, but it is still not clear exactly how.

There's also an additional message when the reconnect happens: "WARNING: POTENTIAL CLIENT.EXPLOIT!", but it requires you to be actively monitoring your log to catch it, and in which case you already get a "Reconnect requested from Pool 0 to 127.0.0.1" message.

Note that disabling 'client.reconnect' might affect some pools that rely on the feature, like pools that you lease your rig to.

Oh and this is dry-coded. :)

d7e469bd76 Stratum servers can now be named. 
The names will be used throughout the display in the program, when not set "Pool 1" will
simply be used instead. The names are not exposed through API yet, it's on my TODO list.

Use "poolname" like this:

	{
		"poolname" : "Example pool",
		"url" : "stratum+tcp://example.com:8080",
		"user" : "y",
		"pass" : "x"
	},

e4680ab627 core: allow changing TCP keepalive packet idle time using tcp-keepalive command-line option or config-file option. 
This may be useful in certain scenarios. However, server load from keepalive
is increased 6-fold if code is hard-changed from 30 to 5. So, provide it as
an option instead, and use the previous value as a default (30).

Explanation from

015c064396

Kevin's middlecoin fix, CURL TCP keepalive constants lowered:

CURLOPT_TCP_KEEPIDLE from 45 to 5 and CURLOPT_TCP_KEEPINTVL from 30 to
5. Before it'd trigger a keepalive packet after 45 seconds of connection
idle time and then again every 30 seconds. Now it triggers a keepalive
packet after 5 seconds of connection idle time and then again every 5
seconds.

It makes the client more resilient against coin switching pools or just
pools with connection issues in general. It will however add a tiny bit
pressure to the pool server; but a TCP keepalive probe is only about
60-80 bytes, so I don't think it is an issue.
