Description Michael Yuniverg 2016-09-14 08:14:07 UTC
as you asked reporting:
 Warning: noted but unhandled ioctl 0x4c01 with no size/direction hints.
(1) ==1149==    This could cause spurious value errors to appear.
(1) ==1149==    See README_MISSING_SYSCALL_OR_IOCTL for guidance on writing a proper wrapper.
(1) --1149-- WARNING: unhandled amd64-linux syscall: 167
(1) --1149-- You may be able to write your own handler.
(1) --1149-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
(1) --1149-- Nevertheless we consider this a bug.  Please report

What platform (OS/architecture) is this?
Comment 2 Mark Wielaard 2016-09-14 11:05:17 UTC
amd64-linux syscall 167 is swapon for which valgrind only has an implementation for mip64, but no other arches apparently.
Comment 3 Julian Seward 2016-09-15 10:44:27 UTC
Hmm, we should pull those wrappers about of being mips64-linux specific
bucket and make them linux-general instead.  Also it looks like they are missing
a PRE_MEM_RASCIIZ call on the path arguments, assuming it's a normal zero
terminated C string.
