[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Muhammad Usama Anjum <usama.anjum@xxxxxxxxxxxxx>

[ Upstream commit 1900be289b598b2c553b3add13e491c0bb8a8550 ]

UBSAN_BOUNDS and UBSAN_TRAP depend on UBSAN config option.
merge_config.sh script generates following warnings if parent config
doesn't have UBSAN config already enabled and UBSAN_BOUNDS/UBSAN_TRAP
config options don't get added to the parent config.

Value requested for CONFIG_UBSAN_BOUNDS not in final .config
Requested value:  CONFIG_UBSAN_BOUNDS=y
Actual value:

Value requested for CONFIG_UBSAN_TRAP not in final .config
Requested value:  CONFIG_UBSAN_TRAP=y
Actual value:

Fix this by including UBSAN config.
