Since that's an assembly stub the # compiler would not generate the proper kCFI indirect call magic and it # would not get patched. # # Brian came up with the most comprehensive fix -- convert the thing to # C with only a very thin asm wrapper. This ensures the kernel thread # boostrap is a proper kCFI call. # # While discussing all this, Kees noted that kCFI hashes could/should be # poisoned to seal all functions whose address is never taken, further # limiting the valid kCFI targets -- much like we already do for IBT. # # So what was a 'simple' observation and fix cascaded into a bunch of # inter-related CFI infrastructure fixes" # # * tag 'x86_urgent_for_6.5_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/cfi: Only define poison_cfi() if CONFIG_X86_KERNEL_IBT=y # x86/fineibt: Poison ENDBR at +0 # x86: Rewrite ret_from_fork() in C # x86/32: Remove schedule_tail_wrapper() # x86/cfi: Extend ENDBR sealing to kCFI # x86/alternative: Rename apply_ibt_endbr() # x86/cfi: Extend {JMP,CAKK}_NOSPEC comment # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 b6e6cc1f78c772e952495b7416c9ac9029f9390c # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- sun3_defconfig # < make -s -j 160 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_sun3_defconfig_m68k-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/swab.h:5, from /kisskb/src/include/uapi/linux/byteorder/big_endian.h:14, from /kisskb/src/include/linux/byteorder/big_endian.h:5, from /kisskb/src/arch/m68k/include/uapi/asm/byteorder.h:5, from /kisskb/src/include/asm-generic/bitops/le.h:6, from /kisskb/src/arch/m68k/include/asm/bitops.h:545, from /kisskb/src/include/linux/bitops.h:68, from /kisskb/src/include/linux/kernel.h:22, from /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:32: /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c: In function 'sun3_82586_timeout': /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:990:108: warning: array subscript 1 is above array bounds of 'volatile struct transmit_cmd_struct *[1]' [-Warray-bounds] printk("%s: command-stats: %04x %04x\n",dev->name,swab16(p->xmit_cmds[0]->cmd_status),swab16(p->xmit_cmds[1]->cmd_status)); ~~~~~~~~~~~~^~~ /kisskb/src/include/uapi/linux/swab.h:107:12: note: in definition of macro '__swab16' __fswab16(x)) ^ /kisskb/src/include/linux/printk.h:455:26: note: in expansion of macro 'printk_index_wrap' #define printk(fmt, ...) printk_index_wrap(_printk, fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~ /kisskb/src/drivers/net/ethernet/i825xx/sun3_82586.c:990:3: note: in expansion of macro 'printk' printk("%s: command-stats: %04x %04x\n",dev->name,swab16(p->xmit_cmds[0]->cmd_status),swab16(p->xmit_cmds[1]->cmd_status)); ^~~~~~ Completed OK # rm -rf /kisskb/build/linus_sun3_defconfig_m68k-gcc8 # Build took: 0:01:41.810165
