H A D | core.h | 20a09c8b Thu Nov 18 08:25:08 CST 2021 Takashi Iwai <tiwai@suse.de> ARM: socfpga: Fix crash with CONFIG_FORTIRY_SOURCE
[ Upstream commit 187bea472600dcc8d2eb714335053264dd437172 ]
When CONFIG_FORTIFY_SOURCE is set, memcpy() checks the potential buffer overflow and panics. The code in sofcpga bootstrapping contains the memcpy() calls are mistakenly translated as the shorter size, hence it triggers a panic as if it were overflowing.
This patch changes the secondary_trampoline and *_end definitions to arrays for avoiding the false-positive crash above.
