      Pull hardened usercopy whitelisting from Kees Cook:
       "Currently, hardened usercopy performs dynamic bounds checking on slab
        cache objects. This is good, but still leaves a lot of kernel memory
        available to be copied to/from userspace in the face of bugs.
      
        To further restrict what memory is available for copying, this creates
        a way to whitelist specific areas of a given slab cache object for
        copying to/from userspace, allowing much finer granularity of access
        control.
      
        Slab caches that are never exposed to userspace can declare no
        whitelist for their objects, thereby keeping them unavailable to
        userspace via dynamic copy operations. (Note, an implicit form of
        whitelisting is the use of constant sizes in usercopy operations and
        get_user()/put_user(); these bypass all hardened usercopy checks since
        these sizes cannot change at runtime.)
      
        This new check is WARN-by-default, so any mistakes can be found over
        the next several releases without breaking anyone's system.
      
        The series has roughly the following sections:
         - remove %p and improve reporting with offset
         - prepare infrastructure and whitelist kmalloc
         - update VFS subsystem with whitelists
         - update SCSI subsystem with whitelists
         - update network subsystem with whitelists
         - update process memory with whitelists
         - update per-architecture thread_struct with whitelists
         - update KVM with whitelists and fix ioctl bug
         - mark all other allocations as not whitelisted
         - update lkdtm for more sensible test overage"

      pinctrl: remove include file from <linux/device.h> · 23c35f48
      Linus Torvalds authored
      
      
      When pulling the recent pinctrl merge, I was surprised by how a
      pinctrl-only pull request ended up rebuilding basically the whole
      kernel.
      
      The reason for that ended up being that <linux/device.h> included
      <linux/pinctrl/devinfo.h>, so any change to that file ended up causing
      pretty much every driver out there to be rebuilt.
      
      The reason for that was because 'struct device' has this in it:
      
          #ifdef CONFIG_PINCTRL
              struct dev_pin_info     *pins;
          #endif
      
      but we already avoid header includes for these kinds of things in that
      header file, preferring to just use a forward-declaration of the
      structure instead.  Exactly to avoid this kind of header dependency.
      
      Since some drivers seem to expect that <linux/pinctrl/devinfo.h> header
      to come in automatically, move the include to <linux/pinctrl/pinctrl.h>
      instead.  It might be better to just make the includes more targeted,
      but I'm not going to review every driver.
      
      It would definitely be good to have a tool for finding and minimizing
      header dependencies automatically - or at least help with them.  Right
      now we almost certainly end up having way too many of these things, and
      it's hard to test every single configuration.
      
      FWIW, you can get a sense of the "hotness" of a header file with something
      like this after doing a full build:
      
          find . -name '.*.o.cmd' -print0 |
              xargs -0 tail --lines=+2 |
              grep -v 'wildcard ' |
              tr ' \\' '\n' |
              sort | uniq -c | sort -n | less -S
      
      which isn't exact (there are other things in those '*.o.cmd' than just
      the dependencies, and the "--lines=+2" only removes the header), but
      might a useful approximation.
      
      With this patch, <linux/pinctrl/devinfo.h> drops to "only" having 833
      users in the current x86-64 allmodconfig.  In contrast, <linux/device.h>
      has 14857 build files including it directly or indirectly.
      
      Of course, the headers that absolutely _everybody_ includes (things like
      <linux/types.h> etc) get a score of 23000+.

      firmware: dmi: handle missing DMI data gracefully · a81114d0
      Ard Biesheuvel authored
      
      
      Currently, when booting a kernel with DMI support on a platform that has
      no DMI tables, the following output is emitted into the kernel log:
      
        [    0.128818] DMI not present or invalid.
        ...
        [    1.306659] dmi: Firmware registration failed.
        ...
        [    2.908681] dmi-sysfs: dmi entry is absent.
      
      The first one is a pr_info(), but the subsequent ones are pr_err()s that
      complain about a condition that is not really an error to begin with.
      
      So let's clean this up, and give up silently if dma_available is not set.

      firmware: dmi_scan: Fix handling of empty DMI strings · a7770ae1
      Jean Delvare authored
      
      
      The handling of empty DMI strings looks quite broken to me:
      * Strings from 1 to 7 spaces are not considered empty.
      * True empty DMI strings (string index set to 0) are not considered
        empty, and result in allocating a 0-char string.
      * Strings with invalid index also result in allocating a 0-char
        string.
      * Strings starting with 8 spaces are all considered empty, even if
        non-space characters follow (sounds like a weird thing to do, but
        I have actually seen occurrences of this in DMI tables before.)
      * Strings which are considered empty are reported as 8 spaces,
        instead of being actually empty.
      
      Some of these issues are the result of an off-by-one error in memcmp,
      the rest is incorrect by design.
      
      So let's get it square: missing strings and strings made of only
      spaces, regardless of their length, should be treated as empty and
      no memory should be allocated for them. All other strings are
      non-empty and should be allocated.

      Jean Delvare authored
      
      
      I don't think it makes sense to check for a possible bad
      initialization order at run time on every system when it is all
      decided at build time.
      
      A more efficient way to make sure developers do not introduce new
      calls to dmi_check_system() too early in the initialization sequence
      is to simply document the expected call order. That way, developers
      have a chance to get it right immediately, without having to
      test-boot their kernel, wonder why it does not work, and parse the
      kernel logs for a warning message. And we get rid of the run-time
      performance penalty as a nice side effect.

      firmware: dmi: Optimize dmi_matches · 8cf4e6a0
      Jean Delvare authored
      Function dmi_matches can me made a bit faster:
      
      * The documented purpose of dmi_initialized is to catch too early
        calls to dmi_check_system(). I'm not fully convinced it justifies
        slowing down the initialization of all systems out there, but at
        least the check should not have been moved from dmi_check_system()
        to dmi_matches(). dmi_matches() is being called for every entry of
        the table passed to dmi_check_system(), causing the same redundant
        check to be performed again and again. So move it back to
        dmi_check_system(), reverting this specific portion of commit
        d7b1956f
      
       ("DMI: Introduce dmi_first_match to make the interface

      Revert "defer call to mem_cgroup_sk_alloc()" · edbe69ef
      Roman Gushchin authored
      This patch effectively reverts commit 9f1c2674 ("net: memcontrol:
      defer call to mem_cgroup_sk_alloc()").
      
      Moving mem_cgroup_sk_alloc() to the inet_csk_accept() completely breaks
      memcg socket memory accounting, as packets received before memcg
      pointer initialization are not accounted and are causing refcounting
      underflow on socket release.
      
      Actually the free-after-use problem was fixed by
      commit c0576e39
      
       ("net: call cgroup_sk_alloc() earlier in
      sk_clone_lock()") for the cgroup pointer.
      
      So, let's revert it and call mem_cgroup_sk_alloc() just before
      cgroup_sk_alloc(). This is safe, as we hold a reference to the socket
      we're cloning, and it holds a reference to the memcg.
      
      Also, let's drop BUG_ON(mem_cgroup_is_root()) check from
      mem_cgroup_sk_alloc(). I see no reasons why bumping the root
      memcg counter is a good reason to panic, and there are no realistic
      ways to hit it.

      net: qlge: use memmove instead of skb_copy_to_linear_data · cfabb177
      Arnd Bergmann authored
      
      
      gcc-8 points out that the skb_copy_to_linear_data() argument points to
      the skb itself, which makes it run into a problem with overlapping
      memcpy arguments:
      
      In file included from include/linux/ip.h:20,
                       from drivers/net/ethernet/qlogic/qlge/qlge_main.c:26:

        memcpy(skb->data, from, len);
      
      It's unclear to me what the best solution is, maybe it ought to use a
      different helper that adjusts the skb data in a safe way. Simply using
      memmove() here seems like the easiest workaround.

      passing the strlen() of the source string as the destination

      net: cxgb4: avoid memcpy beyond end of source buffer · 1a91649f
      Arnd Bergmann authored
      
      
      Building with link-time-optimizations revealed that the cxgb4 driver does
      a fixed-size memcpy() from a variable-length constant string into the
      network interface name:
      
      In function 'memcpy',
          inlined from 'cfg_queues_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:335:2,
          inlined from 'cxgb4_register_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:719:9:
      include/linux/string.h:350:3: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter
         __read_overflow2();
         ^
      
      I can see two equally workable solutions: either we use a strncpy() instead
      of the memcpy() to stop at the end of the input, or we make the source buffer
      fixed length as well. This implements the latter.

      The device could only check the checksum of TCP and UDP packets. Therefore,
      for the IPv4 packets excluding TCP and UDP, the check of checksum is necessary,
      even though the IP checksum is correct.

      Linus Torvalds authored
      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for the v4.16 kernel cycle.
        Like with GPIO it is actually a bit calm this time.
      
        Core changes:
      
         - After lengthy discussions and partly due to my ignorance, we have
           merged a patch making pinctrl_force_default() and
           pinctrl_force_sleep() reprogram the states into the hardware of any
           hogged pins, even if they are already in the desired state.
      
           This only apply to hogged pins since groups of pins owned by
           drivers need to be managed by each driver, lest they could not do
           things like runtime PM and put pins to sleeping state even if the
           system as a whole is not in sleep.
      
        New drivers:
      
         - New driver for the Microsemi Ocelot SoC. This is used in ethernet
           switches.
      
         - The X-Powers AXP209 GPIO driver was extended to also deal with pin
           control and moved over from the GPIO subsystem. This circuit is a
           mixed-mode integrated circuit which is part of AllWinner designs.
      
         - New subdriver for the Qualcomm MSM8998 SoC, core of a high end
           mobile devices (phones) chipset.
      
         - New subdriver for the ST Microelectronics STM32MP157 MPU and
           STM32F769 MCU from the STM32 family.
      
         - New subdriver for the MediaTek MT7622 SoC. This is used for
           routers, repeater, gateways and such network infrastructure.
      
         - New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC
           has multimedia features and target "smart devices", I guess in-car
           entertainment, in-flight entertainment, industrial control panels
           etc.
      
        General improvements:
      
         - Incremental improvements on the SH-PFC subdrivers for things like
           the CAN bus.
      
         - Enable the glitch filter on Baytrail GPIOs used for interrupts.
      
         - Proper handling of pins to GPIO ranges on the Semtec SX150X
      
         - An IRQ setup ordering fix on MCP23S08.
      
         - A good set of janitorial coding style fixes"

       "This seems to have been a comparatively quieter merge window, I assume
        due to holidays etc. The "biggest" change is AMD header cleanups, which
        merge/remove a bunch of them. The AMD gpu scheduler is now being made generic

        can go in the same direction.

      Pull clk updates from Stephen Boyd:
       "The core framework has a handful of patches this time around, mostly
        due to the clk rate protection support added by Jerome Brunet.
      
        This feature will allow consumers to lock in a certain rate on the
        output of a clk so that things like audio playback don't hear pops
        when the clk frequency changes due to shared parent clks changing
        rates. Currently the clk API doesn't guarantee the rate of a clk stays
        at the rate you request after clk_set_rate() is called, so this new
        API will allow drivers to express that requirement.
      
        Beyond this, the core got some debugfs pretty printing patches and a
        couple minor non-critical fixes.
      
        Looking outside of the core framework diff we have some new driver
        additions and the removal of a legacy TI clk driver. Both of these hit
        high in the dirstat. Also, the removal of the asm-generic/clkdev.h
        file causes small one-liners in all the architecture Kbuild files.
      
        Overall, the driver diff seems to be the normal stuff that comes all
        the time to fix little problems here and there and to support new
        hardware.
      
        Summary:
      
        Core:
         - Clk rate protection
         - Symbolic clk flags in debugfs output
         - Clk registration enabled clks while doing bookkeeping updates
      
        New Drivers:
         - Spreadtrum SC9860
         - HiSilicon hi3660 stub
         - Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
         - Amlogic Meson-AXG
         - ASPEED BMC
      
        Removed Drivers:
         - TI OMAP 3xxx legacy clk (non-DT) support
         - asm*/clkdev.h got removed (not really a driver)
      
        Updates:
         - Renesas FDP1-0 module clock on R-Car M3-W
         - Renesas LVDS module clock on R-Car V3M
         - Misc fixes to pr_err() prints
         - Qualcomm MSM8916 audio fixes
         - Qualcomm IPQ8074 rounded out support for more peripherals
         - Qualcomm Alpha PLL variants
         - Divider code was using container_of() on bad pointers
         - Allwinner DE2 clks on H3
         - Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
         - Mediatek clk driver compile test support

      Pull printk updates from Petr Mladek:
      
       - Add a console_msg_format command line option:
      
           The value "default" keeps the old "[time stamp] text\n" format. The
           value "syslog" allows to see the syslog-like "<log
           level>[timestamp] text" format.
      
           This feature was requested by people doing regression tests, for
           example, 0day robot. They want to have both filtered and full logs
           at hands.
      
       - Reduce the risk of softlockup:
      
           Pass the console owner in a busy loop.
      
           This is a new approach to the old problem. It was first proposed by
           Steven Rostedt on Kernel Summit 2017. It marks a context in which
           the console_lock owner calls console drivers and could not sleep.
           On the other side, printk() callers could detect this state and use
           a busy wait instead of a simple console_trylock(). Finally, the
           console_lock owner checks if there is a busy waiter at the end of
           the special context and eventually passes the console_lock to the
           waiter.
      
           The hand-off works surprisingly well and helps in many situations.
           Well, there is still a possibility of the softlockup, for example,
           when the flood of messages stops and the last owner still has too
           much to flush.
      
           There is increasing number of people having problems with
           printk-related softlockups. We might eventually need to get better
           solution. Anyway, this looks like a good start and promising
           direction.
      
       - Do not allow to schedule in console_unlock() called from printk():
      
           This reverts an older controversial commit. The reschedule helped
           to avoid softlockups. But it also slowed down the console output.
           This patch is obsoleted by the new console waiter logic described
           above. In fact, the reschedule made the hand-off less effective.
      
       - Deprecate "%pf" and "%pF" format specifier:
      
           It was needed on ia64, ppc64 and parisc64 to dereference function
           descriptors and show the real function address. It is done
           transparently by "%ps" and "pS" format specifier now.
      
           Sergey Senozhatsky found that all the function descriptors were in
           a special elf section and could be easily detected.
      
       - Remove printk_symbol() API:
      
           It has been obsoleted by "%pS" format specifier, and this change
           helped to remove few continuous lines and a less intuitive old API.
      
       - Remove redundant memsets:
      
           Sergey removed unnecessary memset when processing printk.devkmsg
           command line option.
