fff02cf Kirill 06 February 2018, 09:04:55 UTC USB: serial: cp210x: add new device EZP2010 EZP2010 is a very popular Chinese USB SPI Programmer. Manufacturer provides only windows drivers, but this device is based on Silicon Labs CP210x chip, so it is not so hard to add it to the driver id table. 06 February 2018, 09:04:55 UTC

This time around we have a couple patches shutting off unsupported fs configurations, and a couple of cleanups. Last, we turn off EXPERIMENTAL for the reverse mapping btree, since the primary downstream user of that information (online fsck) is now upstream and I haven't seen any major failures in a few kernel releases. Summary: - Print scrub build status in the xfs build info. - Explicitly call out the remaining two scenarios where we don't support reflink and never have. - Remove EXPERIMENTAL tag from reverse mapping btree!" * tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: remove experimental tag for reverse mapping xfs: don't allow reflink + realtime filesystems xfs: don't allow DAX on reflink filesystems xfs: add scrub to XFS_BUILD_OPTIONS xfs: fix u32 type usage in sb validation function 05 February 2018, 21:35:56 UTC

NFS exporting an overlay filesystem is a challange because we want to keep track of any copy-up of a file or directory between encoding the file handle and decoding it.

2aed489 Amir Goldstein 28 January 2018, 00:35:48 UTC ovl: fix regression in fsnotify of overlay merge dir A re-factoring patch in NFS export series has passed the wrong argument to ovl_get_inode() causing a regression in the very recent fix to fsnotify of overlay merge dir. The regression has caused merge directory inodes to be hashed by upper instead of lower real inode, when NFS export and directory indexing is disabled. That caused an inotify watch to become obsolete after directory copy up and drop caches. LTP test inotify07 was improved to catch this regression. The regression also caused multiple redirect dirs to same origin not to be detected on lookup with NFS export disabled. An xfstest was added to cover this case.

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.

This is needed for guests that will only mitigate Spectre V2 through IBRS+IBPB and will not be using a retpoline+IBPB based approach. To avoid the overhead of saving and restoring the MSR_IA32_SPEC_CTRL for guests that do not actually use the MSR, only start saving and restoring when a non-zero is written to it. No attempt is made to handle STIBP here, intentionally. Filtering STIBP may be added in a future patch, which may require trapping all writes if we don't want to pass it through directly to the guest.

15d4507 Ashok Raj 01 February 2018, 21:59:43 UTC KVM/x86: Add IBPB support The Indirect Branch Predictor Barrier (IBPB) is an indirect branch control mechanism. It keeps earlier branches from influencing later ones. Unlike IBRS and STIBP, IBPB does not define a new mode of operation. It's a command that ensures predicted branch targets aren't used after the barrier. Although IBRS and IBPB are enumerated by the same CPUID enumeration, IBPB is very different. IBPB helps mitigate against three potential attacks: * Mitigate guests from being attacked by other guests. - This is addressed by issing IBPB when we do a guest switch. * Mitigate attacks from guest/ring3->host/ring3. These would require a IBPB during context switch in host, or after VMEXIT. The host process has two ways to mitigate - Either it can be compiled with retpoline - If its going through context switch, and has set !dumpable then there is a IBPB in that path. (Tim's patch: https://patchwork.kernel.org/patch/10192871) - The case where after a VMEXIT you return back to Qemu might make Qemu attackable from guest when Qemu isn't compiled with retpoline. There are issues reported when doing IBPB on every VMEXIT that resulted in some tsc calibration woes in guest. * Mitigate guest/ring0->host/ring0 attacks. When host kernel is using retpoline it is safe against these attacks. If host kernel isn't using retpoline we might need to do a IBPB flush on every VMEXIT. Even when using retpoline for indirect calls, in certain conditions 'ret' can use the BTB on Skylake-era CPUs. There are other mitigations available like RSB stuffing/clearing. * IBPB is issued only for SVM during svm_free_vcpu(). VMX has a vmclear and SVM doesn't. Follow discussion here: https://lkml.org/lkml/2018/1/15/146 Please refer to the following spec for more details on the enumeration and control.

23c35f4 Linus Torvalds 03 February 2018, 00:44:14 UTC pinctrl: remove include file from <linux/device.h> 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+.

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.

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. Signed-off-by: Jean Delvare <jdelvare@suse.de> Cc: Ingo Molnar <mingo@kernel.org> 03 February 2018, 10:25:20 UTC

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 d7b1956fed33 ("DMI: Introduce dmi_first_match to make the interface more flexible"). * Don't check for the exact_match flag again when we already know its value.

edbe69e Roman Gushchin 02 February 2018, 15:26:57 UTC Revert "defer call to mem_cgroup_sk_alloc()" This patch effectively reverts commit 9f1c2674b328 ("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 c0576e397508 ("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.

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" * tag 'pinctrl-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (102 commits) pinctrl: mcp23s08: fix irq setup order pinctrl: Forward declare struct device pinctrl: sunxi: Use of_clk_get_parent_count() instead of open coding pinctrl: stm32: add STM32F769 MCU support pinctrl: sx150x: Add a static gpio/pinctrl pin range mapping pinctrl: sx150x: Register pinctrl before adding the gpiochip pinctrl: sx150x: Unregister the pinctrl on release pinctrl: ingenic: Remove redundant dev_err call in ingenic_pinctrl_probe() pinctrl: sprd: Use seq_putc() in sprd_pinconf_group_dbg_show() pinctrl: pinmux: Use seq_putc() in pinmux_pins_show() pinctrl: abx500: Use seq_putc() in abx500_gpio_dbg_show() pinctrl: mediatek: mt7622: align error handling of mtk_hw_get_value call pinctrl: mediatek: mt7622: fix potential uninitialized value being returned pinctrl: uniphier: refactor drive strength get/set functions pinctrl: imx7ulp: constify struct imx_cfg_params_decode pinctrl: imx: constify struct imx_pinctrl_soc_info pinctrl: imx7d: simplify imx7d_pinctrl_probe pinctrl: imx: use struct imx_pinctrl_soc_info as a const pinctrl: sunxi-pinctrl: fix pin funtion can not be match correctly. pinctrl: qcom: Add msm8998 pinctrl driver ... 02 February 2018, 22:22:53 UTC

60f9182 Kemi Wang 24 October 2017, 01:16:42 UTC buffer: Avoid setting buffer bits that are already set It's expensive to set buffer flags that are already set, because that causes a costly cache line transition. A common case is setting the "verified" flag during ext4 writes. This patch checks for the flag being set first. With the AIM7/creat-clo benchmark testing on a 48G ramdisk based-on ext4 file system, we see 3.3%(15431->15936) improvement of aim7.jobs-per-min on a 2-sockets broadwell platform. What the benchmark does is: it forks 3000 processes, and each process do the following: a) open a new file b) close the file c) delete the file until loop=100*1000 times.

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.

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. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk: (27 commits) printk: drop redundant devkmsg_log_str memsets printk: Never set console_may_schedule in console_trylock() printk: Hide console waiter logic into helpers printk: Add console owner and waiter logic to load balance console writes kallsyms: remove print_symbol() function checkpatch: add pF/pf deprecation warning symbol lookup: introduce dereference_symbol_descriptor() parisc64: Add .opd based function descriptor dereference powerpc64: Add .opd based function descriptor dereference ia64: Add .opd based function descriptor dereference sections: split dereference_function_descriptor() openrisc: Fix conflicting types for _exext and _stext lib: do not use print_symbol() irq debug: do not use print_symbol() sysfs: do not use print_symbol() drivers: do not use print_symbol() x86: do not use print_symbol() unicore32: do not use print_symbol() sh: do not use print_symbol() mn10300: do not use print_symbol() ... 01 February 2018, 21:36:15 UTC

Mostly small clean ups and fixes. The biggest change is to how bprintf works. bprintf is used by trace_printk() to just save the format and args of a printf call, and the formatting is done when the trace buffer is read. This is done to keep the formatting out of the fast path (this was recommended by you). The issue is when arguments are de-referenced. If a pointer is saved, and the format has something like "%*pbl", when the buffer is read, it will de-reference the argument then. The problem is if the data no longer exists. This can cause the kernel to oops. The fix for this was to make these de-reference pointes do the formatting at the time it is called (the fast path), as this guarantees that the data exists (and doesn't change later)" * tag 'trace-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: vsprintf: Do not have bprintf dereference pointers ftrace: Mark function tracer test functions noinline/noclone trace_uprobe: Display correct offset in uprobe_events tracing: Make sure the parsed string always terminates with '\0' tracing: Clear parser->idx if only spaces are read tracing: Detect the string nul character when parsing user input string 01 February 2018, 21:15:23 UTC

This turns out to be because we don't check for a data carrying request on the mq scheduler path, and since blk_phys_contig_segment() returns true for a non-data request, we decrement the initial segment count of 0 and end up with 0xffff in the unsigned short. There are a few issues here: 1) We should initialize the segment count for a discard to 1. 2) The discard merging is currently using the data limits for segments and sectors. Fix this up by having attempt_merge() correctly identify the request, and by initializing the segment count correctly for discards. This can only be triggered with mq-deadline on discard capable devices right now, which isn't a common configuration. Signed-off-by: Jens Axboe <axboe@kernel.dk> 01 February 2018, 21:01:02 UTC
8e44e66 Linus Torvalds 01 February 2018, 20:20:53 UTC Merge branch 'KASAN-read_word_at_a_time' Merge KASAN word-at-a-time fixups from Andrey Ryabinin. The word-at-a-time optimizations have caused headaches for KASAN, since the whole point is that we access byte streams in bigger chunks, and KASAN can be unhappy about the potential extra access at the end of the string. We used to have a horrible hack in dcache, and then people got complaints from the strscpy() case. This fixes it all up properly, by adding an explicit helper for the "access byte stream one word at a time" case. * emailed patches from Andrey Ryabinin <aryabinin@virtuozzo.com>: fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports" fs/dcache: Use read_word_at_a_time() in dentry_string_cmp() lib/strscpy: Shut up KASAN false-positives in strscpy() compiler.h: Add read_word_at_a_time() function. compiler.h, kasan: Avoid duplicating __read_once_size_nocheck() 01 February 2018, 20:20:53 UTC

bfe7aa6 Andrey Ryabinin 01 February 2018, 18:00:51 UTC fs/dcache: Use read_word_at_a_time() in dentry_string_cmp() dentry_string_cmp() performs the word-at-a-time reads from 'cs' and may read slightly more than it was requested in kmallac(). Normally this would make KASAN to report out-of-bounds access, but this was workarounded by commit df4c0e36f1b1 ("fs: dcache: manually unpoison dname after allocation to shut up kasan's reports"). This workaround is not perfect, since it allows out-of-bounds access to dentry's name for all the code, not just in dentry_string_cmp(). So it would be better to use read_word_at_a_time() instead and revert commit df4c0e36f1b1.

1a3241f Andrey Ryabinin 01 February 2018, 18:00:50 UTC lib/strscpy: Shut up KASAN false-positives in strscpy() strscpy() performs the word-at-a-time optimistic reads. So it may may access the memory past the end of the object, which is perfectly fine since strscpy() doesn't use that (past-the-end) data and makes sure the optimistic read won't cross a page boundary. Use new read_word_at_a_time() to shut up the KASAN. Note that this potentially could hide some bugs. In example bellow, stscpy() will copy more than we should (1-3 extra uninitialized bytes): char dst[8]; char *src; src = kmalloc(5, GFP_KERNEL); memset(src, 0xff, 5); strscpy(dst, src, 8); Signed-off-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 01 February 2018, 20:20:21 UTC
