Module Name:src Committed By: martin Date: Sat Jun 3 14:35:18 UTC 2023 Modified Files: src/sys/lib/libsa [netbsd-9]: subr_prf.c Log Message: Pull up following revision(s) (requested by rin in ticket #1636): sys/lib/libsa/subr_prf.c: revision 1.30 libsa/printf: Do not fetch long va_arg as long long. This does real harm iff all of the following conditions are satisfied: (1) On ILP32 architectures. (2) Both LIBSA_PRINTF_LONGLONG_SUPPORT and LIBSA_PRINTF_WIDTH_SUPPORT compile-time options are enabled. (3) Width field is used with 'l' modifier. This is an implicit-fallthrough bug, but unfortunately, GCC 10.4 cannot find this out somehow...

Modified Files:
src/sys/lib/libsa [netbsd-9]: loadfile_elf32.c
Log Message:
Pull up following revision(s) (requested by maxv in ticket #361):
sys/lib/libsa/loadfile_elf32.c: revision 1.56
Make sure we're dealing with a static binary. Otherwise we could crash if
the user mistakenly tries to boot a KASLR kernel with 'boot' instead of
'pkboot'. Now we fail cleanly. Reported by cryo@.
