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 using a caller pre-allocated filled up page as necessary.
Fixes:
https://bugzilla.redhat.com/show_bug.cgi?id=2120480
v2:
- drop some unnecessary changes in the first patch
- use pre-allocated caller memory, instead of allocating in get_next_page()
- fix some comment
Marc-André Lureau (2):
dump: simplify a bit kdump get_next_page()
dump: fix kdump to work over non-aligned blocks
