I'm trying to add crash support for kdumps from kASLR'd kernels. I've got it working with a few small changes and I wanted to solicit comments before sending a patch. 1) The --reloc flag appears to specify an offset to be subtracted from the loaded address, when the aslr offset is added. It's annoying to try to specify negative numbers on the command line, so I'd like to add another argument --aslr which is the same as --reloc but negates the value. 2) There are some symbols which should not be relocated. Specifically the per_cpu section symbols are zero based offsets which should not have the offset apply. Additionally there are VDSO symbols which are fixed even with kASLR enabled. To fix this I'd like to add code to iterate through the section and find the end of the last section and only apply the relocation value to values after the start of text but before the end of the last section. thanks, Andy -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
