Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Michael Kukat (vaxpower) Assigned to: Nobody/Anonymous (nobody) Summary: 5.1.2 jumbo patch for improved AIX 5.2 support Initial Comment: The attached patch enables a lot of functionality for AIX in net-snmp 5.1.2: in mibgroup host, hrStorage is complete for all AIX versions now. hrSWRun is also useable, but information about path and parameters of processes don't come out, as i found no way to gather them. MAC address in interfaces list blanked out, as i currently found no way to get the correct one. Counters are filled with the correct values now. ip/icmp/tcp/udp statistics work on AIX 5.2 for the most common values, but still lots of values are missing. Especially the number of current established connection is missing, as libperfstat only provides the number of established connections since boot. On AIX 4.3.3 and AIX 5.1 all values are still missing, as libperfstat API changed to 5.2 and perfstat_protocol is not present in the previous versions. tcpstats and so are present in running kernel, but all values are zeroed. The attached patch is currently not verified for influence with other platforms, this should be done. Thanks go to Thomas Stark for defining the need and DaimlerChrysler for letting me work out those patches and allowing the contribution of the results to the community. Results are welcome! ---------------------------------------------------------------------- >Comment By: Michael Kukat (vaxpower) Date: 2006-05-11 10:57 Message: Logged In: YES user_id=794829 Thanks for the work, Oliver. Good to see that my work is kept alive in net-snmp, as i don't have the official chance to maintain it like it should be...

Please attach a unified/context diff also. ---------------------------------------------------------------------- Comment By: Michael Kukat (vaxpower) Date: 2005-12-02 14:04 Message: Logged In: YES user_id=794829 After having a quick look at the bug database, i decided to attach out current patch for net-snmp 5.1.2, which provides a quite robust AIX support. This again is plain diff format usable with AIX patch command, as this shall mainly help the users to get some working net-snmp on AIX. The difference to the last diff are just some 64bit issues, which i already saw in newer versions (5.2.1 or so) done for amd64 port. There might always be several endianess problems, which don't appear on amd64, i will dive into this next year with a more current version. In short: If you want net-snmp on AIX, use 5.1.2 with these patches, if you encounter any problems with other versions. And due to libperfstat, net-snmp must be compiled in 64bit on 64bit machines, otherwise the agent will hang or crash on get/walk on some performance related OIDs. ---------------------------------------------------------------------- Comment By: Michael Kukat (vaxpower) Date: 2005-12-02 13:49 Message: Logged In: YES user_id=794829 Took a while for me to have the time to look into this again. I'm still the maintainer of our project around net- snmp, where AIX is still an important platform. We dropped AIX 4.3.3 from out internally supported platforms, 5.1 also is currently not maintained, but the rest is. There were some other minor issues for 64bit i found, but as the base 5.1.2 we use is not really current, i would re-check everything with a more current version next year, when a package upgrade is scheduled (where i also want to upgrade net-snmp). I think this would also be a good point to have a look at the current AIX bugs, as i start with the base net-snmp package than, without patching it first. This is more useful to check the bugs, as i can then insert my comments reflecting some unpatches sf.net version of the source. ---------------------------------------------------------------------- Comment By: Thomas Anders (tanders) Date: 2005-08-19 10:35 Message: Logged In: YES user_id=848638 The most effective way to help would be: - use a fresh CVS checkout (MAIN or V5_2_patches) - (re)submit your patch against this version Also, it'd be extremely helpful to get your opinion on the open AIX bugs in our bug DB. We don't have access to AIX, so it's hard for us to deal with them. Search for Status==Open and Group==aix and add your comments to those bugs, especially the nlist problem (that I think is already fixed). Thanks in advance! ---------------------------------------------------------------------- Comment By: Michael Kukat (vaxpower) Date: 2005-08-19 06:29 Message: Logged In: YES user_id=794829 Besides the machines at work (running 5.2 and 5.3 today, mixed 32 and 64 bit), i have enough machines at home to test 4.3.3 and 5.1, usually also 5.2 is not a problem, as soon as i get my 7043-150 back from a friend. BTW, i recently found a 64bit issue. The AMD64 patches in newer versions also have to be used for AIX (otherwise strange Counter32 values :), and 32bit builds can't be run on 64bit machines (libperfstat issue, can't be fixed, one needs to build 2 versions if he needs 32 and 64 bit support). Want to check all this in a newer version, so i'll send a patch for some 5.2.x if necessary. ---------------------------------------------------------------------- Comment By: Thomas Anders (tanders) Date: 2005-08-19 01:29 Message: Logged In: YES user_id=848638 Do you still have access to AIX just in case we'll ask for a test? ---------------------------------------------------------------------- Comment By: Michael Kukat (vaxpower) Date: 2005-05-13 11:23 Message: Logged In: YES user_id=794829 Here comes a unified diff. This is not applicable on default AIX installations, as patch doesn't know the format. GNU diff required. Hope, this helps the developers here. ---------------------------------------------------------------------- Comment By: Wes Hardaker (hardaker) Date: 2005-05-06 07:38 Message: Logged In: YES user_id=76242 Can you resubit your patch using diff -u instead of a straight diff? It's very hard to apply a diff created the way you submitted it to a moving target (ie, CVS trees). diff -u gives a diff output that is easier to both read and apply. ---------------------------------------------------------------------- Comment By: Michael Kukat (vaxpower) Date: 2005-02-04 12:51 Message: Logged In: YES user_id=794829 Replaced the patch due to a memory leak in hrStorage. This version is intensively tested, no further leaks detected on lots of repeated walks oder .1 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=312694&aid=1102156&group_id=12694 |
