Subject: [PATCH 0/8] generic command line v5
Date: Wed, 28 Sep 2022 19:32:46 -0700 [thread overview]
Message-ID: <20220929023301.3344694-1-danielwa@cisco.com> (raw)
v5 release changes. Generally a rebase from v4.
* Modified OF changes to move the ugly code into the cmdline.h
* Minor compliation update in arm64. Added ifndef __ASSEMBLY__ in
a few places.
* Worked around arm64 kaslr_early.c.
This code needs some additional review and consideration.
It appears this code is missing the opposite option to nokaslr
which is kaslr.disabled=1/0 which would allow kaslr to be turn
back on later in the command line. For example,
console=ttyS0 nokaslr root=/dev/ram0 nosmp kaslr.disabled=0 loglevel=7
On arm64 in arch/arm64/kernel/idreg-override.c this is parsed correctly
to turn on kaslr, but the kaslr_early.c is missing this logic.
Doing this results in kaslr getting disabled with the following message,
KASLR disabled due to lack of seed
Even when there is a seed in the device tree.
So change to the generic command line would leave built in command
lines with nokaslr with no option to re-enable kaslr in in the bootloader
arguments.
