Well now, this brings up another item for the collective TODO list -- implement redzone checks for vmalloc. Unless this is something already taken care of by kasan or similar.

I found a thread that has almost the exact same symptoms as me, but didn't seem to come to a resolution: https://listman.redhat.com/archives/ext3-users/2004-December/msg00018.html I have an LVM(2) array that I've just lvextend'd and want to resize2fs, but I can't get through the e2fsck.

Some times ago, I made a "kmalloc guard" patch that places a magic number immediatelly after the requested size - so that it can detect overflows at byte boundary ( https://www.redhat.com/archives/dm-devel/2014-September/msg00018.html ) That patch found a bug in crypto code: ( http://lkml.iu.edu/hypermail/linux/kernel/1409.1/02325.html ) Mikulas

The kmalloc guard has much lower overhead than kasan. (BTW. when I tried kasan, it oopsed with p...

As discussed in the topic: https://www.redhat.com/archives/libguestfs/2016-March/msg00018.html I'd like to add to libguestfs the disk forensics capabilities offered by The Sleuth Kit. http://www.sleuthkit.org/ The two APIs I'm adding with the patch are a simple example of which type of features TSK can enable. The icat API it's very similar to the previously added ntfscat...

Change distro in the output formally known as virt-inspector to reflect the actual distro. Possible values are now: fedora, rhel, centos, scientific, debian. Add new distrofamily entry which is one of: redhat, debian. Currently all distros except 'debian' are in the redhat family. This allows you to, for example, select a RHEL/CentOS/Scientific Linux specific kernel for installation

The first patch was previously posted here: https://www.redhat.com/archives/libguestfs/2017-December/msg00018.html That patch hasn't changed except that I made the ‘input_transport’ variable type-safe. The second patch adds a significant new mode for liberating data from VMware: the ability to copy VMs over SSH directly from ESXi hypervisors. Although this requires enabling SSH access (a check-box i...
