15 years agox86-64: seccomp: fix 32/64 syscall hole

x86-64: seccomp: fix 32/64 syscall hole

On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with
ljmp, and then use the "syscall" instruction to make a 64-bit system
call.  A 64-bit process make a 32-bit system call with int $0x80.

In both these cases under CONFIG_SECCOMP=y, secure_computing() will use
the wrong system call number table.  The fix is simple: test TS_COMPAT
instead of TIF_IA32.  Here is an example exploit:

/* test case for seccomp circumvention on x86-64

   There are two failure modes: compile with -m64 or compile with -m32.

   The -m64 case is the worst one, because it does "chmod 777 ." (could
   be any chmod call).  The -m32 case demonstrates it was able to do
   stat(), which can glean information but not harm anything directly.

   A buggy kernel will let the test do something, print, and exit 1; a
   fixed kernel will make it exit with SIGKILL before it does anything.

When resuming from suspend newer Synaptics touchpads do not recover
correctly.  Analysis of the resume sequence as applied in Linux was
compared to that of other operating systems.  This indicated that the
