# US-S5-1 — enable remaining Graphene/AXP-class defconfig knobs on msm-4.14.

|
|
# Oracle: AXP/Graphene kernel hardening expects Yama + slab freelist random
|
|
# (combo4 already ships SLAB_FREELIST_HARDENED). LOS sunfish_defconfig left both
|
|
# off; CONFIG_LSM already lists yama but SECURITY_YAMA was unset so the LSM
|
|
# never built.
|
|
#
|
|
# Does NOT apply high-offset CVE leftovers (nf_tables deliberately skipped).
|
|
# CVE-2022-49980's one-liner stays on the denylist. The bacon applies
|
|
# ports/cve-2022-49980-lock-scope.patch after the CVE lists.

|
|
# USERFAULTFD: GOLDEN's running 4.14.355 config leaves it unset. LOS 23
|
|
# sunfish_defconfig turns it on. This kernel has no UFFDIO_MOVE (that ioctl
|
|
# is 6.1+), so ART only opens a fd and times out. Match GOLDEN.

# Usage: apply_uss5_1_defconfig.sh <kernel-tree>
