UPDATE: net/wifind 0.5 -> 0.7

[Ray Lai]

Hi ports,

Attached is a diff to update wifind to 0.7. This release merges
changes from and fixes bugs reported by qbit, iandarwin, and kpcyrd:

- support percentage-based signal strength reporting (iwm)
- support for interface descriptions
- don't die if we don't have an existing hostname.if
- don't validate empty wpakey

Thanks!

Fix exponential glob

[Ray Lai]

As reported in https://research.swtch.com/glob, matching 
aaa with a*a*a*a*a*a*...etc takes exponential time.



Tested with rsc's program: https://news.ycombinator.com/item?id=14187948


I copied the glob implementation from one of the BSDs - I believe 
FreeBSD - into a standalone C program and ran that program on the same 
Linux system as the rest of the tests. Here's the version that tests the 
system glob. If you run it on your FooBSD systems you can see whether it 
runs quickly or not. The program assumes that you've already done:

  rm -rf /tmp/glob
  mkdir /tmp/glob
  cd /tmp/glob
  touch $(perl -e 'print "a"x100')
And here's the program:
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 

  int
  main(void)
  {
  glob_t g;
  char pattern[1000], *p;
  struct timespec t, t2;
  double dt;
  int i, j, k;

  chdir("/tmp/glob");
  setlinebuf(stdout);

  int mul = 1000;
  for(i = 0; i < 100; i++) {
  p = pattern;
  for (k = 0; k < i; k++) {
  *p++ = 'a';
  *p++ = '*';
  }
  *p++ = 'b';
  *p = '\0';
  printf("# %d %s\n", i, pattern);
  clock_gettime(CLOCK_REALTIME, );
  for (j = 0; j < mul; j++) {
  memset(, 0, sizeof g);
  if(glob(pattern, 0, 0, ) != GLOB_NOMATCH) {
  fprintf(stderr, "error: found matches\n");
  exit(2);
  }
  globfree();
  }
  clock_gettime(CLOCK_REALTIME, );
  t2.tv_sec -= t.tv_sec;
  t2.tv_nsec -= t.tv_nsec;
  dt = t2.tv_sec + (double)t2.tv_nsec/1e9;
  printf("%d %.9f\n", i, dt/mul);
  fflush(stdout);
  if(dt/mul >= 0.0001)
  mul = 1;
  if(i >= 8 && dt/mul >= 10)
  break;
  }
  }
I won't be filing any specific bugs myself. I mailed oss-security@ this 
morning, which should reach relevant BSD maintainers, but more bug 
filing can't hurt.

When I run borgbackup, audio (and my mouse) still stutters. Is disk IO 
something that this diff should help with? Anything I can do to help diagnose 
this?

Clean up regress/usr.bin/sdiff

[Ray Lai]

Okan reminded me that my old regress tests used systrace policy files as 
example text, which weren't the easiest to decypher. I've replaced them with 
simpler files that should make life easier for any future regress test writers.

Comments? Suggestions?

improve fuse_parse_opt() parsing

[Ray Lai]

This fixes "sshfs -o idmap=user".

The "if (o->off != ULONG_MAX)" logic is basically
"if (!FUSE_OPT_IS_OPT_KEY(o))" from above, so I stuck it into an else.

New man page: fuse_opt.3

[Ray Lai]

Here's a man page for fuse_opt.h. It's far from perfect, I mostly tried
to document our existing behavior and avoid copying from libfuse. There
are definitely areas of improvement but I think this goes a long way to
helping debug our fuse implementation.

I'm new to fuse, so please, anyone with more fuse knowledge, feel free
to chime in!

.Ft struct fuse_args
holds string options in an array:
.Bd -literal -offset indent
struct fuse_args {
int argc;   /* argument count */
char **argv;/* NULL-terminated array of arguments */
int allocated;  /* allocated by malloc? */
};
.Ed
.Pp
.Fn FUSE_ARGS_INIT
initializes a
.Ft struct fuse_args
with
.Ar argc
and
.Ar argv ,
which can be from
.Fn main .
.Ar argv
is NULL-terminated, and is suitable for use with
.Xr execvp 3 .
.Ar allocated
is set to 0.
.Pp
.Fn fuse_opt_add_arg
adds a single option to the end of
.Ar args .
On
.Ox ,
if
.Ar args->allocated
is 0,
.Ar args->argv
is copied to the heap and
.Ar args->allocated
is set to a non-zero value.
.Pp
.Fn fuse_opt_insert_arg
inserts a single option at position
.Ar p
into
.Ar args ,
shifting
.Ar args->argv
as needed.
(Shifting is currently unimplemented.)
.Pp
.Fn fuse_opt_free_args
frees all allocated memory in
.Ar args
and initializes everything to 0.
.Pp
.Fn fuse_opt_add_opt
adds an option
.Ar opt
to a pointer to an comma-separated string of options
.Ar opts .
.Ar *opts
can be NULL for adding the first option.
.Fn fuse_opt_add_opt_escaped
escapes any
.Sq ","
and
.Sq "\\"
characters in
.Ar opt
before adding it to
.Ar opts .
.Pp
.Fn fuse_opt_match
checks
.Ar opts
for whether
.Ar opt
is set or not.
.Pp
.Fn fuse_opt_parse
parses options.
.Ar opts
is an array of
.Ft struct fuse_opt ,
each which describes actions for each option:
.Bd -literal -offset indent
struct fuse_opt {
const char *templ;  /* template for option */
unsigned long off;  /* data offset */
int val;/* key value */
};
.Ed
.Pp
.Fn FUSE_OPT_KEY
returns a
.Ft struct fuse_opt
that matches an option
.Ar templ
with option key
.Ar key .
This function is used as an element in
.Ft struct fuse_opt
arrays.
.Fn FUSE_OPT_IS_OPT_KEY
checks if
.Ar t
is an option key.
.Pp
The last element of the
.Ar opts
.Ft struct fuse_opt
option array must be
.Dv FUSE_OPT_END .
.Pp
.Ar proc
points to a function with the following signature:
.Ft int (*fuse_opt_proc_t)
.Fo proc
.Fa "void *data"
.Fa "const char *arg"
.Fa "int key"
.Fa "struct fuse_args *outargs"
.Fc
.Pp
Special key values:
.Bd -literal -offset indent
FUSE_OPT_KEY_OPT/* no match */
FUSE_OPT_KEY_NONOPT /* non-option */
FUSE_OPT_KEY_KEEP   /* don't process; return 1 */
FUSE_OPT_KEY_DISCARD/* don't process; return 0
