Bug#95079: libsmi2: Build failure on PARISC [fwd]
by Remco van de Meent 26 Apr '01

26 Apr '01

Hi! Some feedback I got from someone running Debian GNU/Linux on PARISC... instead of me updating the 'local' config.{guess,sub} files I guess it would be better if Frank or Juergen could do that if they want to... cheers, Remco. ----- Forwarded message from LaMont Jones <lamont(a)smallone.fc.hp.com> ----- Subject: Bug#95079: libsmi2: Build failure on PARISC From: LaMont Jones <lamont(a)smallone.fc.hp.com> To: submit(a)bugs.debian.org Date: Tue, 24 Apr 2001 00:21:38 -0600 (MDT) Package: libsmi2 Version: 0.2.16-1 Severity: normal The config.guess and config.sub files in the source need to be updated to the current ones (at http://subversions.gnu.org/cgi-bin/cvsweb/config).

Segmentation fault in smiLoadModule
by sndtrn4＠hss.hns.com 21 Apr '01

21 Apr '01

Hi! I'm getting a segmentation fault in smiLoadModule when the mibs imported by the mib I load cannot be found. Also, the error comes *not* while loading the errant module, but when I call smiLoadModule for the next mib. (I get the error messages on screen for the first mib saying such and such modules could not be loaded). The debugger tells me that smiLoadModule calls loadModule on line (415)in smi.c which then calls a parse function on line (3461) in data.c, which then goes to parser-smi.y in line (2107), where the segmentation fault occurs in structure referred to as $6.

memory deallocation

Hi! Is there any specific cleanup function in the library that removes the nodes that are returned to me? Or do I simple call free() when I no longer need the node? Mayank. -- !!

Re: [libsmi] problem with smiGetNodeByOid
by sndtrn4＠hss.hns.com 13 Apr '01

Hi! I've got the solution now; it was a problem in the mib. I had not imported "enterprises". Thanks, Mayank. Frank Strauss <strauss(a)ibr.cs.tu-bs.de> on 04/13/2001 07:31:59 PM To: Mayank Agarwal/HSS@HSS cc: Subject: Re: [libsmi] problem with smiGetNodeByOid Hi! sndtrn4> Sorry for the confusion. What I wanted to highlight was that sndtrn4> though I can get a node correctly by name, I cannot get it by sndtrn4> oid (fully qualified or partial), if the mib contains an sndtrn4> imported mib. That is, if a.my imports SNMPv2-SMI and has the sndtrn4> first object id as ------- me OBJECT IDENTIFIER ::= { sndtrn4> enterprises 4 } , I cannot get "me" by oid. Please give a detailed example with all required data so that I can reconstruct your problem. In my recent mail I gave you I piece of code that works fine for me and I suggest to check whether your module is valid. Did you try my code? Did you check your module(s) with smilint?

Re: [libsmi] Are ranges allowed in SEQUENCEs?
by Bill Fenner 13 Apr '01

ASN.1 may allow subtyping in SEQUENCEs; the SMI does not. See http://www.aciri.org/fenner/mibs/libsmi-errors/subtype-in-sequence.html or RFC 2578 section 7.1.12 . Bill -- !!

Are ranges allowed in SEQUENCEs?
by Andy Stone 12 Apr '01

12 Apr '01

I am compiling some private mibs with libsmi 0.2.14 and am getting errors. However these mibs compile correctly with another mib compiler (Epilogue). I am trying to figure out whether these problems are because the libsmi is less forgiving then Epilogue, or because of a problem in libsmi. Basically, I try to create a sequence as follows: ChrComHWEquipmentEntry ::= SEQUENCE { a Integer32 (0..65535), b INTEGER, c INTEGER (1..3) } When compiled, I get the following errors: test2.mib:24: subtyping not allowed in SEQUENCE test2.mib:26: subtyping not allowed in SEQUENCE (in other words, "a" and "c" have do not work, but "b" does) Basically, it seems like libsmi does not like you to put in range limitations. When I examined x.680 (the asn.1 spec), I was unable to prove that the range format is valid in that location. Basically, I needed to get from the "Constraint section" (ie all of the xxxconstraint rules) over to SubtypeElements. However, the language rules do not seem complete, in that I cannot find the definition for "GeneralConstraint". Does anyone know what the correct syntax is? If so do you know of an official document discussing this topic? Thanks, Andy gastone(a)lucent.com PS: Below is my test mib file, my config file, & a dump of the smidump output: ChrComHWEquipment-MIB DEFINITIONS ::= BEGIN IMPORTS OBJECT-TYPE, Integer32 FROM SNMPv2-SMI; -- chrComHWEquipment Table chr MODULE-IDENTITY LAST-UPDATED "9905170000Z" ORGANIZATION "Cc."

problem with smiGetNodeByOid
by sndtrn4＠hss.hns.com 12 Apr '01

12 Apr '01

Hi! There was a typo in my last mail, i wrote "child" instead of "node". Here's the code: I'm having a problem finding a node by the oid. After loading the mib, I'm using the following code segment: scanf("%s", strNode); node = smiGetNode(NULL, strNode); node = smiGetNodeByOID(node->oidlen, node->oid); if (node) { printf("Node name: %s\n", node->name); } else { printf("Node not found"); } With the input "enterprises", I'm getting the output "ccitt", which isn't even there in my mib (SNMPv2-SMI). With a mib loaded that imports this one, I can get correct output till the level of "enterprises", but below this I get the result "enterprises" for all inputs. I have verified that the node is being found correctly in the first call smiGetNode(). Thanks in advance, Mayank. -- !! This message is brought to you via the `libsmi' mailing list. !!
