Linus Torvalds e94f8ccde4 I have four patches for v5.4. Nothing is major. All but one are in
response to mechanically detected potential issues. The remaining
 patch cleans up kernel-doc notations.

Linus Torvalds 1b5fb41544 Merge tag 'safesetid-bugfix-5.4' of git://github.com/micah-morton/linux
Pull SafeSetID fix from Micah Morton:
 "Jann Horn sent some patches to fix some bugs in SafeSetID for 5.3.
  After he had done his testing there were a couple small code tweaks
  that went in and caused this bug.

  From what I can see SafeSetID is broken in 5.3 and crashes the kernel
  every time during initialization if you try to use it. I came across
  this bug when backporting Jann's changes for 5.3 to older kernels
  (4.14 and 4.19). I've tested on a Chrome OS device with those kernels
  and verified that this change fixes things.

  It doesn't seem super useful to have this bake in linux-next, since it
  is completely broken in 5.3 and nobody noticed"

Merge tag 'selinux-pr-20190917' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

 - Add LSM hooks, and SELinux access control hooks, for dnotify,
   fanotify, and inotify watches. This has been discussed with both the
   LSM and fs/notify folks and everybody is good with these new hooks.

 - The LSM stacking changes missed a few calls to current_security() in
   the SELinux code; we fix those and remove current_security() for
   good.

 - Improve our network object labeling cache so that we always return
   the object's label, even when under memory pressure. Previously we
   would return an error if we couldn't allocate a new cache entry, now
   we always return the label even if we can't create a new cache entry
   for it.

 - Convert the sidtab atomic_t counter to a normal u32 with
   READ/WRITE_ONCE() and memory barrier protection.

 - A few patches to policydb.c to clean things up (remove forward
   declarations, long lines, bad variable names, etc)

Jens Axboe 32960613b7 io_uring: correctly handle non ->{read,write}_iter() file_operations
Currently we just -EINVAL a read or write to an fd that isn't backed
by ->read_iter() or ->write_iter(). But we can handle them just fine,
as long as we punt fo async context first.

Implement a simple loop function for doing ->read() or ->write()
instead, and ensure we call it appropriately.

Max Gurtovoy be21683e48 block: t10-pi: fix -Wswitch warning
Changing the switch() statement to symbolic constants made the compiler
(at least clang-9, did not check gcc) notice that there is one enum value
that is not handled here:

block/t10-pi.c:62:11: error: enumeration value 'T10_PI_TYPE0_PROTECTION'
not handled in switch [-Werror,-Wswitch]

Add a BUG_ON statement if we ever get to t10_pi_verify function with
TYPE0 and replace the switch() statement with if/else clause for the
valid types.

Linus Torvalds 5d4156ac48 firmware: bcm47xx_nvram: _really_ correct size_t printf format
Commit feb4eb060c ("firmware: bcm47xx_nvram: Correct size_t printf
format") was wrong, and changed a printout of 'header.len' - which is an
u32 type - to use '%zu'.

It apparently did pattern matching on the other case, where it printed
out 'nvram_len', which is indeed of type 'size_t'.

Rather than undoing the change, this just makes it use the variable that
the change seemed to expect to be used.

Linus Torvalds 3e4d890a26 modules: make MODULE_IMPORT_NS() work even when modular builds are disabled
It's an unusual configuration, and was apparently never tested, and not
caught in linux-next because of a combination of travels and it making
it into the tree too late.

The fix is to simply move the #define to outside the CONFIG_MODULE
section, since MODULE_INFO() will do the right thing.

Linus Torvalds e070355664 Modules updates for v5.4
Summary of modules changes for the 5.4 merge window:
 
 - Introduce exported symbol namespaces.
 
   This new feature allows subsystem maintainers to partition and
   categorize their exported symbols into explicit namespaces. Module
   authors are now required to import the namespaces they need.
 
   Some of the main motivations of this feature include: allowing kernel
   developers to better manage the export surface, allow subsystem
   maintainers to explicitly state that usage of some exported symbols
   should only be limited to certain users (think: inter-module or
   inter-driver symbols, debugging symbols, etc), as well as more easily
   limiting the availability of namespaced symbols to other parts of the
   kernel. With the module import requirement, it is also easier to spot
   the misuse of exported symbols during patch review. Two new macros are
   introduced: EXPORT_SYMBOL_NS() and EXPORT_SYMBOL_NS_GPL(). The API is
   thoroughly documented in Documentation/kbuild/namespaces.rst.
 
 - Some small code and kbuild cleanups here and there.

Merge tag 'modules-for-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux

Pull modules updates from Jessica Yu:
 "The main bulk of this pull request introduces a new exported symbol
  namespaces feature. The number of exported symbols is increasingly
  growing with each release (we're at about 31k exports as of 5.3-rc7)
  and we currently have no way of visualizing how these symbols are
  "clustered" or making sense of this huge export surface.

  Namespacing exported symbols allows kernel developers to more
  explicitly partition and categorize exported symbols, as well as more
  easily limiting the availability of namespaced symbols to other parts
  of the kernel. For starters, we have introduced the USB_STORAGE
  namespace to demonstrate the API's usage. I have briefly summarized
  the feature and its main motivations in the tag below.

  Summary:

   - Introduce exported symbol namespaces.

     This new feature allows subsystem maintainers to partition and
     categorize their exported symbols into explicit namespaces. Module
     authors are now required to import the namespaces they need.

     Some of the main motivations of this feature include: allowing
     kernel developers to better manage the export surface, allow
     subsystem maintainers to explicitly state that usage of some
     exported symbols should only be limited to certain users (think:
     inter-module or inter-driver symbols, debugging symbols, etc), as
     well as more easily limiting the availability of namespaced symbols
     to other parts of the kernel.

     With the module import requirement, it is also easier to spot the
     misuse of exported symbols during patch review.

     EXPORT_SYMBOL_NS_GPL(). The API is thoroughly documented in

Linus Torvalds 5c6bd5de3c Main MIPS changes for v5.4:
- boot_mem_map is removed, providing a nice cleanup made possible by the
   recent removal of bootmem.
 
 - Some fixes to atomics, in general providing compiler barriers for
   smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
   MIPS32 systems using cmpxchg64().
 
 - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
   Frascino.
 
 - Removal of undefined behavior in set_io_port_base(), fixing the
   behavior of some MIPS kernel configurations when built with recent
   clang versions.
 
 - Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
 
 - pte_special() is now supported for some configurations, allowing among
   other things generic fast GUP to be used.
 
 - Miscellaneous fixes & cleanups.
 
 And platform specific changes:
 
 - Major improvements to Ingenic SoC support from Paul Cercueil, mostly
   enabled by the inclusion of the new TCU (timer-counter unit) drivers
   he's spent a very patient year or so working on. Plus some fixes for
   X1000 SoCs from Zhou Yanjie.
 
 - Netgear R6200 v1 systems are now supported by the bcm47xx platform.
 
 - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.
