[PATCH 0/2] Fix dumping in kdump format with non-aligned memory

Posted by marcandre.lureau@redhat.com 1 year, 8 months ago

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

dump.c:get_next_page expects GuestPhysBlock to be page-aligned, and crashes over
memory regions such as "tpm-crb-cmd". Teach it to handle non-aligned regions
too, by returning allocated and filled up pages as necessary.

Fixes:

Marc-André Lureau (2):
  dump: simplify a bit kdump get_next_page()
  dump: fix kdump to work over non-aligned blocks
