      add match_strlcpy() us it to make v9fs make uname and remotename parsing more robust · b32a09db

      match_strcpy() is a somewhat creepy function: the caller needs to make sure
      that the destination buffer is big enough, and when he screws up or
      forgets, match_strcpy() happily overruns the buffer.
      
      There's exactly one customer: v9fs_parse_options().  I believe it currently
      can't overflow its buffer, but that's not exactly obvious.
      
      The source string is a substing of the mount options.  The kernel silently
      truncates those to PAGE_SIZE bytes, including the terminating zero.  See
      compat_sys_mount() and do_mount().
      
      The destination buffer is obtained from __getname(), which allocates from
      name_cachep, which is initialized by vfs_caches_init() for size PATH_MAX.
      
      We're safe as long as PATH_MAX <= PAGE_SIZE.  PATH_MAX is 4096.  As far as
      I know, the smallest PAGE_SIZE is also 4096.
      
      Here's a patch that makes the code a bit more obviously correct.  It
      doesn't depend on PATH_MAX <= PAGE_SIZE.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
