Rather than using debugger commands, it allows users to write Python code that treats the kernel’s data structures like regular Python objects. It supports standard ELF core dumps (and the running kernel) natively, and it relies on libkdumpfile to understand other formats, like kdump-compressed...

Obsolete features: • The ctf_module_dump tool has been removed. It is no longer needed. Bugfixes: • The substr() and strjoin() subroutines now correctly store the result string length in the string length prefix. Internal changes: • The temporary string (tstring) support in the ...
After a multivolume dump has been mounted, it is shown as a single dump file that can be accessed directly with dump processing tools such as crash. The following example mounts a multivolume DASD dump as an ELF dump, processes it with crash, and unmounts it with zgetdump: # zgetdump ...
When you compile the kernel with-gand run the debugger usingvmlinuxtogether with/proc/kcore,gdbcan return a lot of information about the kernel internals. You can, for example, use commands such asp *module_list,p *module_list->next, andp *chrdevs[4]->fopsto dump structures. To get ...
(e.g., a program still has an open file for a device exported by the modules), or if the kernel has been configured to disallow module removal. It is possible to configure the kernel to allow âforcedâ removal of modules, even when they appear to be busy. If you...
