RE: Seems that I found bugs related to stash_cashe in 5.7...

Hi Bart,

 

Thanks for the reply.  First of all, I didn't claimed that stash_cache
works in 5.6, I have no 5.6 at all...

I know that injectHandler works after your patch (as you stated that you
saw : injectHandler: injecting handler cache_handler into
nsModuleTable), but what does not work is the stash_cache itself. I
mean: stash cache has no effect and it is not being called at all. Only
after my 2 other patches I saw that it begun to work. To check if
stash_cache is being invoked or not is very simple: only add
-Dhelper:stash_cache to cmd line. If during nsModuleTable SNMP walk, you
see a lot of stash_cache log lines, it means that it is doing its work.
If you don't see anything relating stash_cache, it means that is has no
effect ...

 

Ivo

The first and immediate fix is to: 

#define NETSNMP_FEATURE_HAS_STASH_CACHE

In a place that all_helpers.c will see it


That's wrong because that would break the configure option
--enable-minimal. See also
https://sourceforge.net/tracker/?group_id=12694&atid=312694 for a proper
patch.
 

	Add to your snmpd.conf:

	injectHandler stash_cache nsModuleTable table_iterator

	 

	try to execute snmpd with follow cmd line:

	snmpd
-DinjectHandler,helper:stash_cache,initialize_table_nsModuleTable -c
snmpd.conf


What I see in the logs with both 5.7 and 5.6 after having applied the
aforementioned patch is:

injectHandler: injecting handler cache_handler into nsModuleTable

So iterator injection seems to work fine.

But I'm not sure that your claim is correct that the stash_cache is
working fine in 5.6 - a MIB walk times out at the end of the host
resources MIB with 5.6:

$ agent/snmpd -Mmibs -c ../snmpd.conf -f -Lo
-DinjectHandler,helper:stash_cache,initialize_table_nsModuleTable :1161
&
[ ... ]
$ apps/snmpwalk -Mmibs -v2c -cpublic :1161 .1
[ ... ]
HOST-RESOURCES-MIB::hrSWRunPerfMem.32504 = INTEGER: 663508 KBytes
Timeout: No Response from :1161

The above test works fine with 5.4 and 5.5 however.

Bart.
