374bf88 | Linus Torvalds | 29 June 2017, 21:10:37 UTC | Merge branch 'for-linus' of git://git.kernel.dk/linux-block Pull block fixes from Jens Axboe: "Two fixes that should go into this release. One is an nvme regression fix from Keith, fixing a missing queue freeze if the controller is being reset. This causes the reset to hang. The other is a fix for a leak of the bio protection info, if smaller sized O_DIRECT is used. This fix should be more involved as we have other problematic paths in the kernel, but given as this isn't a regression in this series, we'll tackle those for 4.13" * 'for-linus' of git://git.kernel.dk/linux-block: block: provide bio_uninit() free freeing integrity/task associations nvme/pci: Fix stuck nvme reset | 29 June 2017, 21:10:37 UTC |

Remove the implementations as well. Some architectures use thread_saved_pc() in their arch-specific code. Leave their thread_saved_pc() intact.

9ae3b3f | Jens Axboe | 28 June 2017, 21:30:13 UTC | block: provide bio_uninit() free freeing integrity/task associations Wen reports significant memory leaks with DIF and O_DIRECT: "With nvme devive + T10 enabled, On a system it has 256GB and started logging /proc/meminfo & /proc/slabinfo for every minute and in an hour it increased by 15968128 kB or ~15+GB.. Approximately 256 MB / minute leaking. /proc/meminfo | grep SUnreclaim... SUnreclaim: 6752128 kB SUnreclaim: 6874880 kB SUnreclaim: 7238080 kB ....

The patch fixes the issue. HTX has been run with +60 hours without failure." Since __blkdev_direct_IO_simple() allocates the bio on the stack, it doesn't go through the regular bio free. This means that any ancillary data allocated with the bio through the stack is not freed. Hence, we can leak the integrity data associated with the bio, if the device is using DIF/DIX. Fix this by providing a bio_uninit() and export it, so that we can use it to free this data. Note that this is a minimal fix for this issue. Any current user of bio's that are allocated outside of bio_alloc_bioset() suffers from this issue, most notably some drivers. We will fix those in a more comprehensive patch for 4.13. This also means that the commit marked as being fixed by this isn't the real culprit, it's just the most obvious one out there.

26fcd95 | Thomas Gleixner | 23 June 2017, 08:50:38 UTC | x86/mshyperv: Remove excess #includes from mshyperv.h A recent commit included linux/slab.h in linux/irq.h. This breaks the build of vdso32 on a 64-bit kernel. The reason is that linux/irq.h gets included into the vdso code via linux/interrupt.h which is included from asm/mshyperv.h. That makes the 32-bit vdso compile fail, because slab.h includes the pgtable headers for 64-bit on a 64-bit build. Neither linux/clocksource.h nor linux/interrupt.h are needed in the mshyperv.h header file itself - it has a dependency on <linux/atomic.h>. Remove the includes and unbreak the build.

98da7d0 | Kees Cook | 23 June 2017, 22:08:57 UTC | fs/exec.c: account for argv/envp pointers When limiting the argv/envp strings during exec to 1/4 of the stack limit, the storage of the pointers to the strings was not included. This means that an exec with huge numbers of tiny strings could eat 1/4 of the stack limit in strings and then additional space would be later used by the pointers to the strings. For example, on 32-bit with a 8MB stack rlimit, an exec with 1677721 single-byte strings would consume less than 2MB of stack, the max (8MB / 4) amount allowed, but the pointers to the strings would consume the remaining additional stack space (1677721 * 4 == 6710884). The result (1677721 + 6710884 == 8388605) would exhaust stack space entirely. Controlling this stack exhaustion could result in pathological behavior in setuid binaries (CVE-2017-1000365).

8818efa | Eric Ren | 23 June 2017, 22:08:55 UTC | ocfs2: fix deadlock caused by recursive locking in xattr Another deadlock path caused by recursive locking is reported. This kind of issue was introduced since commit 743b5f1434f5 ("ocfs2: take inode lock in ocfs2_iop_set/get_acl()"). Two deadlock paths have been fixed by commit b891fa5024a9 ("ocfs2: fix deadlock issue when taking inode lock at vfs entry points"). Yes, we intend to fix this kind of case in incremental way, because it's hard to find out all possible paths at once. This one can be reproduced like this.

SyS_delete_module+0x5/0x1f0 entry_SYSCALL_64_fastpath+0x1f/0xc2 It'd be the cleanest to deal with the issue by removing sysfs files without holding slab_mutex before the rest of shutdown; however, given the current code structure, it is pretty difficult to do so. This patch punts sysfs file removal to a work item. Before commit bf5eb3de3847, the removal was punted to a RCU delayed work item which is executed after release. Now, we're punting to a different work item on shutdown which still maintains the goal removing the sysfs files earlier when destroying kmem_caches.

This is not un unreasonable assumption to make, but on architectures that have CONFIG_HAVE_ARCH_HUGE_VMAP=y, it no longer holds, and we need to ensure that vmalloc_to_page() does not go off into the weeds trying to dereference huge PUDs or PMDs as table entries. Given that vmalloc() and vmap() themselves never create huge mappings or deal with compound pages at all, there is no correct answer in this case, so return NULL instead, and issue a warning. When reading /proc/kcore on arm64, you will hit an oops as soon as you hit the huge mappings used for the various segments that make up the mapping of vmlinux. With this patch applied, you will no longer hit the oops, but the kcore contents willl be incorrect (these regions will be zeroed out) We are fixing this for kcore specifically, so it avoids vread() for those regions. At least one other problematic user exists, i.e., /dev/kmem, but that is currently broken on arm64 for other reasons.

c891d9f | David Rientjes | 23 June 2017, 22:08:38 UTC | mm, thp: remove cond_resched from __collapse_huge_page_copy This is a partial revert of commit 338a16ba1549 ("mm, thp: copying user pages must schedule on collapse") which added a cond_resched() to __collapse_huge_page_copy(). On x86 with CONFIG_HIGHPTE, __collapse_huge_page_copy is called in atomic context and thus scheduling is not possible. This is only a possible config on arm and i386. Although need_resched has been shown to be set for over 100 jiffies while doing the iteration in __collapse_huge_page_copy, this is better than doing if (in_atomic()) cond_resched() to cover only non-CONFIG_HIGHPTE configs.

The asce token origin must not be used to generate an effective address for storage references. This however is erroneously done within kvm_s390_shadow_tables(). Furthermore within the same function the wrong parts of virtual addresses are used to generate a corresponding real address (e.g. the region second index is used as region first index). Both of the above can result in incorrect address translations. Only for real space designations with a token origin of zero and addresses below one megabyte the translation was correct. Furthermore replace a "!asce.r" statement with a "!*fake" statement to make it more obvious that a specific condition has nothing to do with the architecture, but with the fake handling of real space designations.

SPI and I2C devices are expected to be enumerated by the SPI and I2C subsystems but change caused that acpi_bus_attach() marks those devices with acpi_device_set_enumerated(). First group of devices are matched using Device Tree compatible property with special _HID "PRP0001". Those devices have matched scan handler, acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them with acpi_device_set_enumerated(). Second group of devices without valid _HID such as "LNXVIDEO" have device->pnp.type.platform_id set to zero and change again marks them with acpi_device_set_enumerated(). Fix this by flagging the SPI and I2C devices during struct acpi_device object initialization time and let the code in acpi_bus_attach() to go through the device_attach() and acpi_default_enumeration() path for all SPI and I2C devices.

8e8320c | Jens Axboe | 20 June 2017, 23:56:13 UTC | blk-mq: fix performance regression with shared tags If we have shared tags enabled, then every IO completion will trigger a full loop of every queue belonging to a tag set, and every hardware queue for each of those queues, even if nothing needs to be done. This causes a massive performance regression if you have a lot of shared devices. Instead of doing this huge full scan on every IO, add an atomic counter to the main queue that tracks how many hardware queues have been marked as needing a restart. With that, we can avoid looking for restartable queues, if we don't have to. Max reports that this restores performance. Before this patch, 4K IOPS was limited to 22-23K IOPS. With the patch, we are running at 950-970K IOPS.

07f6155 | Serhey Popovych | 20 June 2017, 10:29:25 UTC | ipv6: Do not leak throw route references While commit 73ba57bfae4a ("ipv6: fix backtracking for throw routes") does good job on error propagation to the fib_rules_lookup() in fib rules core framework that also corrects throw routes handling, it does not solve route reference leakage problem happened when we return -EAGAIN to the fib_rules_lookup() and leave routing table entry referenced in arg->result. If rule with matched throw route isn't last matched in the list we overwrite arg->result losing reference on throw route stored previously forever. We also partially revert commit ab997ad40839 ("ipv6: fix the incorrect return value of throw route") since we never return routing table entry with dst.error == -EAGAIN when CONFIG_IPV6_MULTIPLE_TABLES is on. Also there is no point to check for RTF_REJECT flag since it is always set throw route.

7e11332 | Krzysztof Kozlowski | 19 June 2017, 16:05:41 UTC | dt-bindings: net: sms911x: Add missing optional VDD regulators The lan911x family of devices require supplying from 3.3 V power supplies (connected to VDD_IO, VDD_A and VREG_3.3 pins). The existing driver however obtains only VDD_IO and VDD_A regulators in an optional way so document this in bindings.
