Subject: [PATCH 01/30] Fix kernel version macros for revision numbers over 255
|
|
|
|
The current comparison macros for kernel version shift minor number only
|
|
8 bits. This can cause an unexpected result on kernels with revision
|
|
number over 255, e.g. Linux 4.14.314.
|
|
|
|
In fact, on Linux 4.14.314 for x86_64 without CONFIG_RANDOMIZE_BASE=y
|
|
(KASLR), the following condition became false in x86_64_init().
|
|
|
|
((THIS_KERNEL_VERSION >= LINUX(4,14,84)) &&
|
|
(THIS_KERNEL_VERSION < LINUX(4,15,0)))
|
|
|
|
As a result, crash used a wrong hard-coded value for PAGE_OFFSET and
|
|
failed to start a session with the following seek error.
|
|
|
|
crash: seek error: physical address: 200e000 type: "pud page"
|
|
|
|
Shift the major and minor number by 24 and 16 bits respectively to fix
|
|
this issue.
