      Wrap accesses to the fd_sets in struct fdtable · 1dce27c5
      David Howells authored
      Wrap accesses to the fd_sets in struct fdtable (for recording open files and
      close-on-exec flags) so that we can move away from using fd_sets since we
      abuse the fd_set structs by not allocating the full-sized structure under
      normal circumstances and by non-core code looking at the internals of the
      fd_sets.
      
      The first abuse means that use of FD_ZERO() on these fd_sets is not permitted,
      since that cannot be told about their abnormal lengths.
      
      This introduces six wrapper functions for setting, clearing and testing
      close-on-exec flags and fd-is-open flags:
      
      	void __set_close_on_exec(int fd, struct fdtable *fdt);
      	void __clear_close_on_exec(int fd, struct fdtable *fdt);
      	bool close_on_exec(int fd, const struct fdtable *fdt);
      	void __set_open_fd(int fd, struct fdtable *fdt);
      	void __clear_open_fd(int fd, struct fdtable *fdt);
      	bool fd_is_open(int fd, const struct fdtable *fdt);
      
      Note that I've prepended '__' to the names of the set/clear functions because
      they require the caller to hold a lock to use them.
      
      Note also that I haven't added wrappers for looking behind the scenes at the
      the array.  Possibly that should exist too.

      merge fchmod() and fchmodat() guts, kill ancient broken kludge · e57712eb
      Al Viro authored
      The kludge in question is undocumented and doesn't work for 32bit
      binaries on amd64, sparc64 and s390.  Passing (mode_t)-1 as
      mode had (since 0.99.14v and contrary to behaviour of any
      other Unix, prescriptions of POSIX, SuS and our own manpages)
      was kinda-sorta no-op.  Note that any software relying on
      that (and looking for examples shows none) would be visibly
      broken on sparc64, where practically all userland is built
      32bit.  No such complaints noticed...
