Souptick Joarder b57e622e6d mm/hmm: convert to use vm_fault_t
Convert to use vm_fault_t type as return type for fault handler.

kbuild reported warning during testing of
*mm-create-the-new-vm_fault_t-type.patch* available in below link -
https://patchwork.kernel.org/patch/10752741/

  kernel/memremap.c:46:34: warning: incorrect type in return expression
                           (different base types)
  kernel/memremap.c:46:34: expected restricted vm_fault_t
  kernel/memremap.c:46:34: got int

This patch has fixed the warnings and also hmm_devmem_fault() is
converted to return vm_fault_t to avoid further warnings.

Zev Weiss 2bc4fc60fb kernel/sysctl.c: define minmax conv functions in terms of non-minmax versions
do_proc_do[u]intvec_minmax_conv() had included open-coded versions of
do_proc_do[u]intvec_conv(); the duplication led to buggy inconsistencies
(missing range checks).  To reduce the likelihood of such problems in the
future, we can instead refactor both to be defined in terms of their
non-bounded counterparts (plus the added check).

Zev Weiss 8cf7630b29 kernel/sysctl.c: add missing range check in do_proc_dointvec_minmax_conv
This bug has apparently existed since the introduction of this function
in the pre-git era (4500e91754d3 in Thomas Gleixner's history.git,
"[NET]: Add proc_dointvec_userhz_jiffies, use it for proper handling of
neighbour sysctls.").

As a minimal fix we can simply duplicate the corresponding check in
do_proc_dointvec_conv().

Zev Weiss fec5248668 tools/testing/selftests/sysctl/sysctl.sh: add tests for >32-bit values written to 32-bit integers
Patch series "sysctl: fix range-checking in do_proc_dointvec_minmax_conv()", v2.

After being left with an unusable system after a typo executing
something like 'echo $((1<<24)) > /proc/sys/vm/max_map_count', I found
that do_proc_dointvec_minmax_conv() was missing a check to ensure that
the converted value actually fits in an int.

The first of the following patches enhances the sysctl selftest such
that it detects this problem; the second provides a minimal fix
(suitable for -stable) such that the selftest passes.  The third patch
then performs a more thorough refactoring to eliminate the code
duplication that led to the bug in the first place (maintaining the
passing status of the selftest).

This patch (of 3):

At present this exposes a bug in do_proc_dointvec_minmax_conv() (it
fails to check for values that are too wide to fit in an int).

Linus Torvalds 6bc3fe8e7e tools: mark 'test_vmalloc.sh' executable
Several of these scripts have come in as old-fashioned patches, and in
the process lost the executable bit.  In most cases it doesn't matter,
since the test infrastructure will explicitly execute them using the
proper shell interpreter, but at least in the case of the new vmalloc
test, the lack of execurable bit caused the test to fail with

    ./run_vmtests: line 217: ./test_vmalloc.sh: Permission denied

because of the lacking exectuable permissions bit.

This patch fixes that up.

NOTE! A simple script to look for non-executable scripts in the kernel,
something like

    git ls-files --stage -- '*.sh' |
        grep 100644 |
        cut -f2 |
        xargs grep -l '#!'

will show that there's a lot of other files that _look_ like executable
shell scripts, but don't have the executable bit set.  I considered just
scripting them all to be executable, but since it looks like the common
pattern is to not really require it, I'm just doing the minimal fix as
pointed out by the kernel test robot.

Linus Torvalds 5af7f11588 Merge branch 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull tpm updates from James Morris:

 - Clean up the transmission flow

   Cleaned up the whole transmission flow. Locking of the chip is now
   done in the level of tpm_try_get_ops() and tpm_put_ops() instead
   taking the chip lock inside tpm_transmit(). The nested calls inside
   tpm_transmit(), used with the resource manager, have been refactored
   out.

   Should make easier to perform more complex transactions with the TPM
   without making the subsystem a bigger mess (e.g. encrypted channel
   patches by James Bottomley).

 - PPI 1.3 support

   TPM PPI 1.3 introduces an additional optional command parameter that
   may be needed for some commands. Display the parameter if the command
   requires such a parameter. Only command 23 (SetPCRBanks) needs one.

   The PPI request file will show output like this then:

      # echo "23 16" > request
      # cat request
      23 16

      # echo "5" > request
      # cat request
      5

 - Extend all PCR banks in IMA

   Instead of static PCR banks array, the array of available PCR banks
   is now allocated dynamically. The digests sizes are determined
   dynamically using a probe PCR read without relying crypto's static
   list of hash algorithms.

   This should finally make sealing of measurements in IMA safe and
   secure.

 - TPM 2.0 selftests

   Added a test suite to tools/testing/selftests/tpm2 previously outside
   of the kernel tree: https://github.com/jsakkine-intel/tpm2-scripts

Pull integrity updates from James Morris:
 "Mimi Zohar says:

   'Linux 5.0 introduced the platform keyring to allow verifying the IMA
    kexec kernel image signature using the pre-boot keys. This pull
    request similarly makes keys on the platform keyring accessible for
    verifying the PE kernel image signature.

    Also included in this pull request is a new IMA hook that tags tmp
    files, in policy, indicating the file hash needs to be calculated.
    The remaining patches are cleanup'"

* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
  evm: Use defined constant for UUID representation

Gustavo A. R. Silva fbf68b01a8 ide: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/ide/ide-floppy.c: In function ‘ide_floppy_get_capacity’:
drivers/ide/ide-floppy.c:424:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
    if (!(drive->atapi_flags & IDE_AFLAG_CLIK_DRIVE))
       ^
drivers/ide/ide-floppy.c:431:3: note: here
   case CAPACITY_CURRENT:
   ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

Eric Dumazet 2a5ff07a0e gro_cells: make sure device is up in gro_cells_receive()
We keep receiving syzbot reports [1] that show that tunnels do not play
the rcu/IFF_UP rules properly.

At device dismantle phase, gro_cells_destroy() will be called
only after a full rcu grace period is observed after IFF_UP
has been cleared.

This means that IFF_UP needs to be tested before queueing packets
into netif_rx() or gro_cells.

This patch implements the test in gro_cells_receive() because
too many callers do not seem to bother enough.

Eric Dumazet 59cbf56fcd vxlan: test dev->flags & IFF_UP before calling gro_cells_receive()
Same reasons than the ones explained in commit 4179cb5a4c
("vxlan: test dev->flags & IFF_UP before calling netif_rx()")

netif_rx() or gro_cells_receive() must be called under a strict contract.

At device dismantle phase, core networking clears IFF_UP
and flush_all_backlogs() is called after rcu grace period
to make sure no incoming packet might be in a cpu backlog
and still referencing the device.

A similar protocol is used for gro_cells infrastructure, as
gro_cells_destroy() will be called only after a full rcu
grace period is observed after IFF_UP has been cleared.

Most drivers call netif_rx() from their interrupt handler,
and since the interrupts are disabled at device dismantle,
netif_rx() does not have to check dev->flags & IFF_UP

Virtual drivers do not have this guarantee, and must
therefore make the check themselves.

Otherwise we risk use-after-free and/or crashes.

Eric Dumazet 95d6ebd53c net/x25: fix use-after-free in x25_device_event()
In case of failure x25_connect() does a x25_neigh_put(x25->neighbour)
but forgets to clear x25->neighbour pointer, thus triggering use-after-free.

Since the socket is visible in x25_list, we need to hold x25_list_lock
to protect the operation.

Shiju Jose 69b51bbb03 net: hns3: fix to stop multiple HNS reset due to the AER changes
The commit bfcb79fca1
("PCI/ERR: Run error recovery callbacks for all affected devices")
affected the non-fatal error recovery logic for the HNS and RDMA devices.
This is because each HNS PF under PCIe bus receive callbacks
from the AER driver when an error is reported for one of the PF.
This causes unwanted PF resets because
the HNS decides which PF to reset based on the reset type set.
The HNS error handling code sets the reset type based on the hw error
type detected.

This patch provides fix for the above issue for the recovery of
the hw errors in the HNS and RDMA devices.

This patch needs backporting to the kernel v5.0+

Linus Torvalds d1cae94871 fscrypt updates for v5.1
First: Ted, Jaegeuk, and I have decided to add me as a co-maintainer for
 fscrypt, and we're now using a shared git tree.  So we've updated
 MAINTAINERS accordingly, and I'm doing the pull request this time.
 
 The actual changes for v5.1 are:
 
 - Remove the fs-specific kconfig options like CONFIG_EXT4_ENCRYPTION and
   make fscrypt support for all fscrypt-capable filesystems be controlled
   by CONFIG_FS_ENCRYPTION, similar to how CONFIG_QUOTA works.
 
 - Improve error code for rename() and link() into encrypted directories.
 
 - Various cleanups.
