  33
  34    All code is copied verbatim from kernel source files, except that:
  35    - VKI_/vki_ prefixes are added
  36    - some extra explanatory comments are included;  they are all within
  37      "[[ ]]"
  38    - for some types, we only care about the size;  for a few of them (big
  39      ones that are painful to fully drag in here), a VKI_SIZEOF_* constant
  40      is used.

2465  * PJF this is a bit messy
2466  *
2467  * mode_t is uint16_t
2468  * No problem on x86/amd64
2469  * On arm64 there are syscalls that take mode_t but that doesn't
2470  * work with memcheck validation - arm64 doesn't have any 16bit
2471  * registers.
2472  *
2473  * I can't just change mode_t to be 32bit. that will mess up
2474  * the 'stat' structures in this file.
2475  *
2476  * Instead I'll just do what the compiler does, and promote
2477  * it to 32bits.
2478  *
2479  * In the kernel, the syscall interface just pushes all
2480  * possible syscall args onto the stack and then
2481  * memcpy's them into an array of register sized args.
2482  * There's a struct defined for each syscall's arguments
2483  * that uses padding to type pun the values back to
2484  * the type passed in from userland. The structs are
2485  * generated from the syscall table.
2486  *
2487  * vki_mode_t is only used in syswrap files so there shouldn't
2488  * be any other side effects.
