Libsmi 0.4.3 memory fault (Linux/gcc)
by Allen McIntosh 03 May '05

The libsmi parser memory faults when parsing mibs/ietf/DOT12-RPTR-MIB. Repeat by running smilint mibs/ietf/DOT12-RPTR-MIB after installing libsmi. This happened to me under RedHat 9 (gcc 3.2.2/x86) and RedHat 7.3 (gcc 2.96/x86). The parser usually runs off the rails thus: $ gdb /usr/local/bin/smilint [stuff omitted] (gdb) run mibs/ietf/DOT12-RPTR-MIB Starting program: /usr/local/bin/smilint mibs/ietf/DOT12-RPTR-MIB mibs/ietf/DOT12-RPTR-MIB:36: revision for last update is missing mibs/ietf/DOT12-RPTR-MIB:151: warning: use Integer32 instead of INTEGER in SMIv2 Program received signal SIGSEGV, Segmentation fault. 0x40037b15 in checkObjects (parserPtr=0xbffff5f0, modulePtr=0x80559a0) at parser-smi.y:220 220 if (objectPtr->nodePtr->parentPtr && (gdb) where #0 0x40037b15 in checkObjects (parserPtr=0xbffff5f0, modulePtr=0x80559a0) at parser-smi.y:220 #1 0x4003a26c in smiparse (parserPtr=0xbffff5f0) at parser-smi.y:1641 #2 0x40031021 in loadModule ( modulename=0xbffff841 "mibs/ietf/DOT12-RPTR-MIB", parserPtr=0x0) at data.c:3792 #3 0x40035110 in smiLoadModule (module=0xbffff841 "mibs/ietf/DOT12-RPTR-MIB") at smi.c:416 #4 0x080492f2 in main (argc=2, argv=0xbffff6f4) at smilint.c:314 #5 0x42017589 in __libc_start_main () from /lib/i686/libc.so.6 (gdb) print objectPtr->nodePtr->parentPtr $1 = (struct Node *) 0x62696d2f Running with ElectricFence and EF_PROTECT_BELOW on turns up a problem, if that helps. I can provide details if that would help.

Thanks to all who contributed to this issue. I've just comitted a new revision to the libsmi SVN repository that handles OID and identifiers in the "NameAndNumberForm" more acurately, and also emits warnings such as... ./XXX-MIB:165: warning: object identifier for label `snmpDot3MauMgt' does not match previous label usage ./XXX-MIB:40: info: previous definition of `snmpDot3MauMgt' ./XXX-MIB:165: warning: label `snmpDot3MauMgtXXX' does not match previous label `snmpDot3MauMgt' for same object identifier ./XXX-MIB:40: info: previous definition of `snmpDot3MauMgt'

parser compilation problem
by miksiu 29 Nov '04

Hello! I'm working with libsmi-0.4.1 and I have one problem. I don't know what options was used to compile parser-smi.y file. I compiled this file with command (I didn't make any changes in this file): bison -d parser-smi.y and after this I have two files: parser-smi.tab.c 294KB parser-smi.tab.h 7KB Size of these files is different than size of original files in libsmi-0.4.1 (in turn: 292KB and 1KB). In addition when I try to compile whole libsmi library with original parser files, everything is allright, but with these files which I got as a result of bison's work I have error: NMAKE : fatal error U1077: 'cl' : return code '0x2' To compile library I use makefile file from win directory as it is shown in README.win file. Maybe the original files were compiled with other options or I do some mistakes during compilation parser-smi.y file. Help me, please! Tom

using libsmi

Hi all!! My name is Tom and i'm from Poland. I'm new at this lists. I have one question about libsmi. When I compile and install the library into for example: C:/smilib-0.4.1 I have to files in C:\smilib-0.4.1\ : libsmi.a 798kB libsmi.la 1kB What should I do now in my main program. I wrote (Visual C++ 6.0): #pragma comment(lib, "C:\\smilib-0.4.1\\lib\\libsmi.a") but it doesn't work and there are linker errors for example: libsmi.a(data.o) : error LNK2001: unresolved external symbol __imp___ctype_ Other older versions of my program used other lib files. In the install library directory were two files after installing: smiDEBUG.lib 775kB smi_MT.lib 566kB and it works without problems. Please for any requests as soon as possible!!! Regards!!! Tom
