mm: refactor readahead defines in mm.h
All users of VM_MAX_READAHEAD actually convert it to kbytes and then to pages. Define the macro explicitly as (SZ_128K / PAGE_SIZE). This simplifies the expression in every filesystem. Also rename the macro to VM_READAHEAD_PAGES to properly convey its meaning. Finally remove unused VM_MIN_READAHEAD [akpm@linux-foundation.org: fix fs/io_uring.c, per Stephen] Link: http://lkml.kernel.org/r/20181221144053.24318-1-nborisov@suse.com Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: Matthew Wilcox <willy@infradead.org> Reviewed-by: David Hildenbrand <david@redhat.com> Cc: Jens Axboe <axboe@kernel.dk> Cc: Eric Van Hensbergen <ericvh@gmail.com> Cc: Latchesar Ionkov <lucho@ionkov.net> Cc: Dominique Martinet <asmadeus@codewreck.org> Cc: David Howells <dhowells@redhat.com> Cc: Chris Mason <clm@fb.com> Cc: Josef Bacik <josef@toxicpanda.com> Cc: David Sterba <dsterba@suse.com> Cc: Miklos Szeredi <miklos@szeredi.hu> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

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).

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().

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).

Merge branch 'x86-tsx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 tsx fixes from Thomas Gleixner: "This update provides kernel side handling for the TSX erratum of Intel Skylake (and later) CPUs. On these CPUs Intel Transactional Synchronization Extensions (TSX) functions can result in unpredictable system behavior under certain circumstances. The issue is mitigated with an microcode update which utilizes Performance Monitoring Counter (PMC) 3 when TSX functions are in use. This mitigation is enabled unconditionally by the updated microcode. As a consequence the usage of TSX functions can cause corrupted performance monitoring results for events which utilize PMC3. The corruption is silent on kernels which have no update for this issue. This update makes the kernel aware of the PMC3 utilization by the microcode: The microcode offers a possibility to enforce TSX abort which prevents the malfunction and frees up PMC3. The enforced TSX abort requires the TSX using application to have a software fallback path implemented; abort handlers which solely retry the transaction will fail over and over. The enforced TSX abort request is issued by the kernel when: - enforced TSX abort is enabled (PMU attribute) - A performance monitoring request needs PMC3 When PMC3 is not longer used by the kernel the TSX force abort request is cleared. The enforced TSX abort mechanism is enabled by default and can be controlled by the administrator via the new PMU attribute 'allow_tsx_force_abort'. This attribute is only visible when updated microcode is detected on affected systems. Writing '0' disables the enforced TSX abort mechanism, '1' enables it. As a result of disabling the enforced TSX abort mechanism, PMC3 is permanentely unavailable for performance monitoring which can cause performance monitoring requests to fail or switch to multiplexing mode" * branch 'x86-tsx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/intel: Implement support for TSX Force Abort x86: Add TSX Force Abort CPUID/MSR perf/x86/intel: Generalize dynamic constraint creation perf/x86/intel: Make cpuc allocations consistent |

The biggest change for this release is in the histogram code.
- Add "onchange(var)" histogram handler that executes a action when $var
changes.
- Add new "snapshot()" action for histogram handlers, that causes a
snapshot of the ring buffer when triggered.
ie. onchange(var).snapshot() will trigger a snapshot if var changes.
- Add alternative for "trace()" action.
Currently, to trigger a synthetic event, the name of that event is used
as the handler name, which is inconsistent with the other actions.
onchange(var).synthetic(param) where it can now be
onchange(var).trace(synthetic, param). The older method will still be
allowed, as long as the synthetic events do not overlap with other
handler names.
- The histogram documentation at testcases were updated for the new
changes.
Added a quicker way to enable set_ftrace_filter files, that will make
it much quicker to bisect tracing a function that shouldn't be traced and
crashes the kernel. (You can echo in numbers to set_ftrace_filter, and it
will select the corresponding function that is in
available_filter_functions).
Some better displaying of the tracing data (and more information was added).
The rest are small fixes and more clean ups to the code.

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.
Fixes:

mailbox: imx: keep MU irq working during suspend/resume
During noirq suspend phase, mailbox MU irq will be masked but many drivers still need to communicate with system controller firmware via mailbox, if MU irq is masked, it will cause RPC timeout as below: [ 23.372103] imx-scu scu: RPC send msg timeout Setting MU irq to be wakeup source is NOT working as GIC driver does NOT have .irq_set_wake implemented, so to support suspend/resume, just make imx mailbox driver NOT suspend, since MU is always a wakeup source on i.MX platforms with system controller inside, and its power/clock is maintained by system controller, mailbox driver no need to manage them.

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
* 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (37 commits)

cases where we are expecting to fall through.
This patch fixes the following warning:

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.

SUNRPC: Take the transport send lock before binding+connecting
Before trying to bind a port, ensure we grab the send lock to ensure that we don't change the port while another task is busy transmitting requests. The connect code already takes the send lock in xprt_connect(), but it is harmless to take it before that. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> |

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.

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. syzbot report : BUG: KASAN: use-after-free in x25_kill_by_device net/x25/af_x25.c:217 [inline] BUG:
