There isn't anything wrong with "provably" (capable of being proved, synonym: demonstrably). emerge --info please Created attachment 318662 [details]
emerge --info
Here.
Seeing same issue on sys-kernel/hardened-sources-3.4.5. Dies at arch/x86/kernel/tls.o in function '__copy_from_user' inlined from 'regset_tls_set' at arch/x86/kernel/tls.c:212:27: arch/x86/include/asm/uaccess_64.h:110:26: error: call to 'copy_from_user_overflow' declared with attribute error: copy_from_user() buffer size not provably correct. Unfortunately machine is not network-accessible so can't provide emerge --info. Created attachment 322609 [details]
