[Crash-utility] [PATCH] fix for '/proc/version' check

Hi Dave! It can happen that crash does not extract the correct Linux version string from vmlinux. Therefore the comparison with /proc/version fails at startup: WARNING: /usr/lib/debug/lib/modules/2.6.17-1.2519.4.21.el5/vmlinux and /proc/version do not match! Crash gets the release string by searching strings in vmlinux. Something like: On our system the string does not start with "Linux...", but with "0Linux...". Therefore crash assumes a wrong version string. To fix this, we should skip the leading "0": --- diff o-Naur crash-4.0-3.3/filesys.c crash-4.0-3.3-proc-version-check-fix/filesys.c --- crash-4.0-3.3/filesys.c 2006-09-07 21:00:08.000000000 +0200 +++ crash-4.0-3.3-proc-version-check-fix/filesys.c 2006-09-13 15:36:54.000000000 +0200 @@ -244,10 +244,12 @@ found = FALSE; while (fgets(buffer, BUFSIZE-1, pipe)) { - if (!strstr(buffer, "Linux version 2.")) + char* ptr; + ptr = strstr(buffer, "Linux version 2."); + if (!ptr) continue; - if (STREQ(buffer, kt->proc_version)) + if (STREQ(ptr, kt->proc_version)) found = TRUE; break; }
