Linus Torvalds 2475c515d4 Merge tag 'staging-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO updates from Greg KH:
 "Here are the big staging/iio patches for 4.19-rc1.

  Lots of churn here, with tons of cleanups happening in staging
  drivers, a removal of an old crypto driver that no one was using
  (skein), and the addition of some new IIO drivers. Also added was a
  "gasket" driver from Google that needs loads of work and the erofs
  filesystem.

  Even with adding all of the new drivers and a new filesystem, we are
  only adding about 1000 lines overall to the kernel linecount, which
  shows just how much cleanup happened, and how big the unused crypto
  driver was.

  All of these have been in the linux-next tree for a while now with no
  reported issues"

Johannes Berg says:

====================
This round's updates:
 * finally some of the promised HE code, but it turns
   out to be small - but everything kept changing, so
   one part I did in the driver was >30 patches for
   what was ultimately <200 lines of code ... similar
   here for this code.
 * improved scan privacy support - can now specify scan
   flags for randomizing the sequence number as well as
   reducing the probe request element content
 * rfkill cleanups
 * a timekeeping cleanup from Arnd
 * various other cleanups

Jia-Ju Bai ac5e4875e6 staging: rtlwifi: Fix a possible sleep-in-atomic-context bug in _is_fw_read_cmd_down()
The driver may sleep with holding a spinlock.
The function call path (from bottom to top) in Linux-4.16.7 is:

[FUNC] schedule
drivers/staging/rtlwifi/halmac/rtl_halmac.c, 884:
		schedule in _is_fw_read_cmd_down
drivers/staging/rtlwifi/halmac/rtl_halmac.c, 912:
		_is_fw_read_cmd_down in rtl_halmac_send_h2c
drivers/staging/rtlwifi/halmac/rtl_halmac.c, 907:
		_raw_spin_lock_irqsave in rtl_halmac_send_h2c

To fix this bug, schedule() is replaced with mdelay(1).

This bug is found by my static analysis tool (DSAC-2) and checked by
my code review.

Kees Cook 6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

Greg Kroah-Hartman e206a0d47e staging: rtlwifi: don't check the return value of debugfs_create_file
We never did anything with the return value, and it does not matter if
the call succeeds or not (it's just debugging code), so don't even check
it.

Tiezhu Yang dad459e052 staging: rtlwifi: use single_open and single_release properly
single_open() returns -ENOMEM when malloc failed, so the caller function
rtl_debugfs_open_rw() should not always return 0. In addition, when using
single_open(), we should use single_release() instead of seq_release() in
the file_operations structure to avoid a memory leak.
