789ba28 Mel Gorman 09 May 2018, 16:31:15 UTC Revert "sched/numa: Delay retrying placement for automatic NUMA balance after wake_affine()" This reverts commit 7347fc87dfe6b7315e74310ee1243dc222c68086. Srikar Dronamra pointed out that while the commit in question did show a performance improvement on ppc64, it did so at the cost of disabling active CPU migration by automatic NUMA balancing which was not the intent. The issue was that a serious flaw in the logic failed to ever active balance if SD_WAKE_AFFINE was disabled on scheduler domains. Even when it's enabled, the logic is still bizarre and against the original intent. Investigation showed that fixing the patch in either the way he suggested, using the correct comparison for jiffies values or introducing a new numa_migrate_deferred variable in task_struct all perform similarly to a revert with a mix of gains and losses depending on the workload, machine and socket count. The original intent of the commit was to handle a problem whereby wake_affine, idle balancing and automatic NUMA balancing disagree on the appropriate placement for a task. This was particularly true for cases where a single task was a massive waker of tasks but where wake_wide logic did not apply. This was particularly noticeable when a futex (a barrier) woke all worker threads and tried pulling the wakees to the waker nodes. In that specific case, it could be handled by tuning MPI or openMP appropriately, but the behavior is not illogical and was worth attempting to fix. However, the approach was wrong. Given that we're at rc4 and a fix is not obvious, it's better to play safe, revert this commit and retry later.

e438302 Ashish Samant 11 May 2018, 23:02:07 UTC ocfs2: take inode cluster lock before moving reflinked inode from orphan dir While reflinking an inode, we create a new inode in orphan directory, then take EX lock on it, reflink the original inode to orphan inode and release EX lock. Once the lock is released another node could request it in EX mode from ocfs2_recover_orphans() which causes downconvert of the lock, on this node, to NL mode. Later we attempt to initialize security acl for the orphan inode and move it to the reflink destination. However, while doing this we dont take EX lock on the inode. This could potentially cause problems because we could be starting transaction, accessing journal and modifying metadata of the inode while holding NL lock and with another node holding EX lock on the inode. Fix this by taking orphan inode cluster lock in EX mode before initializing security and moving orphan inode to reflink destination. Use the __tracker variant while taking inode lock to avoid recursive locking in the ocfs2_init_security_and_acl() call chain.

27ae357 David Rientjes 11 May 2018, 23:02:04 UTC mm, oom: fix concurrent munlock and oom reaper unmap, v3 Since exit_mmap() is done without the protection of mm->mmap_sem, it is possible for the oom reaper to concurrently operate on an mm until MMF_OOM_SKIP is set. This allows munlock_vma_pages_all() to concurrently run while the oom reaper is operating on a vma. Since munlock_vma_pages_range() depends on clearing VM_LOCKED from vm_flags before actually doing the munlock to determine if any other vmas are locking the same memory, the check for VM_LOCKED in the oom reaper is racy. This is especially noticeable on architectures such as powerpc where clearing a huge pmd requires serialize_against_pte_lookup(). If the pmd is zapped by the oom reaper during follow_page_mask() after the check for pmd_none() is bypassed, this ends up deferencing a NULL ptl or a kernel oops. Fix this by manually freeing all possible memory from the mm before doing the munlock and then setting MMF_OOM_SKIP. The oom reaper can not run on the mm anymore so the munlock is safe to do in exit_mmap(). It also matches the logic that the oom reaper currently uses for determining when to set MMF_OOM_SKIP itself, so there's no new risk of excessive oom killing. This issue fixes CVE-2018-1000200.

ae646f0 Jeffrey Hugo 11 May 2018, 23:01:42 UTC init: fix false positives in W+X checking load_module() creates W+X mappings via __vmalloc_node_range() (from layout_and_allocate()->move_module()->module_alloc()) by using PAGE_KERNEL_EXEC. These mappings are later cleaned up via "call_rcu_sched(&freeinit->rcu, do_free_init)" from do_init_module(). This is a problem because call_rcu_sched() queues work, which can be run after debug_checkwx() is run, resulting in a race condition. If hit, the race results in a nasty splat about insecure W+X mappings, which results in a poor user experience as these are not the mappings that debug_checkwx() is intended to catch. This issue is observed on multiple arm64 platforms, and has been artificially triggered on an x86 platform. Address the race by flushing the queued work before running the arch-defined mark_rodata_ro() which then calls debug_checkwx().

be83bbf Linus Torvalds 11 May 2018, 16:52:01 UTC mmap: introduce sane default mmap limits The internal VM "mmap()" interfaces are based on the mmap target doing everything using page indexes rather than byte offsets, because traditionally (ie 32-bit) we had the situation that the byte offset didn't fit in a register. So while the mmap virtual address was limited by the word size of the architecture, the backing store was not. So we're basically passing "pgoff" around as a page index, in order to be able to describe backing store locations that are much bigger than the word size (think files larger than 4GB etc). But while this all makes a ton of sense conceptually, we've been dogged by various drivers that don't really understand this, and internally work with byte offsets, and then try to work with the page index by turning it into a byte offset with "pgoff << PAGE_SHIFT". Which obviously can overflow. Adding the size of the mapping to it to get the byte offset of the end of the backing store just exacerbates the problem, and if you then use this overflow-prone value to check various limits of your device driver mmap capability, you're just setting yourself up for problems. The correct thing for drivers to do is to do their limit math in page indices, the way the interface is designed. Because the generic mmap code _does_ test that the index doesn't overflow, since that's what the mmap code really cares about. HOWEVER. Finding and fixing various random drivers is a sisyphean task, so let's just see if we can just make the core mmap() code do the limiting for us. Realistically, the only "big" backing stores we need to care about are regular files and block devices, both of which are known to do this properly, and which have nice well-defined limits for how much data they can access. So let's special-case just those two known cases, and then limit other random mmap users to a backing store that still fits in "unsigned long". Realistically, that's not much of a limit at all on 64-bit, and on 32-bit architectures the only worry might be the GPU drivers, which can have big physical address spaces. To make it possible for drivers like that to say that they are 64-bit clean, this patch does repurpose the "FMODE_UNSIGNED_OFFSET" bit in the file flags to allow drivers to mark their file descriptors as safe in the full 64-bit mmap address space. [ The timing for doing this is less than optimal, and this should really go in a merge window. But realistically, this needs wide testing more than it needs anything else, and being main-line is the only way to do that. So the earlier the better, even if it's outside the proper development cycle - Linus ] Cc: Kees Cook <keescook@chromium.org> Cc: Dan Carpenter <dan.carpenter@oracle.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Willy Tarreau <w@1wt.eu> Cc: Dave Airlie <airlied@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 11 May 2018, 16:52:01 UTC

21706ee Debabrata Banerjee 09 May 2018, 23:32:11 UTC bonding: send learning packets for vlans on slave There was a regression at some point from the intended functionality of commit f60c3704e87d ("bonding: Fix alb mode to only use first level vlans.") Given the return value vlan_get_encap_level() we need to store the nest level of the bond device, and then compare the vlan's encap level to this. Without this, this check always fails and learning packets are never sent. In addition, this same commit caused a regression in the behavior of balance_alb, which requires learning packets be sent for all interfaces using the slave's mac in order to load balance properly. For vlan's that have not set a user mac, we can send after checking one bit. Otherwise we need send the set mac, albeit defeating rx load balancing for that vlan.

dc432c3 Steven Rostedt (VMware) 09 May 2018, 15:59:32 UTC tracing: Fix regex_match_front() to not over compare the test string The regex match function regex_match_front() in the tracing filter logic, was fixed to test just the pattern length from testing the entire test string. That is, it went from strncmp(str, r->pattern, len) to strcmp(str, r->pattern, r->len). The issue is that str is not guaranteed to be nul terminated, and if r->len is greater than the length of str, it can access more memory than is allocated. The solution is to add a simple test if (len < r->len) return 0.

32bee8f Lukas Wunner 09 May 2018, 12:43:43 UTC can: hi311x: Work around TX complete interrupt erratum When sending packets as fast as possible using "cangen -g 0 -i -x", the HI-3110 occasionally latches the interrupt pin high on completion of a packet, but doesn't set the TXCPLT bit in the INTF register. The INTF register contains 0x00 as if no interrupt has occurred. Even waiting for a few milliseconds after the interrupt doesn't help. Work around this apparent erratum by instead checking the TXMTY bit in the STATF register ("TX FIFO empty"). We know that we've queued up a packet for transmission if priv->tx_len is nonzero. If the TX FIFO is empty, transmission of that packet must have completed. Note that this is congruent with our handling of received packets, which likewise gleans from the STATF register whether a packet is waiting in the RX FIFO, instead of looking at the INTF register.

5cec942 Lukas Wunner 09 May 2018, 12:38:43 UTC can: hi311x: Acquire SPI lock on ->do_get_berr_counter hi3110_get_berr_counter() may run concurrently to the rest of the driver but neglects to acquire the lock protecting access to the SPI device. As a result, it and the rest of the driver may clobber each other's tx and rx buffers. We became aware of this issue because transmission of packets with "cangen -g 0 -i -x" frequently hung. It turns out that agetty executes ->do_get_berr_counter every few seconds via the following call stack: CPU: 2 PID: 1605 Comm: agetty [<7f3f7500>] (hi3110_get_berr_counter [hi311x]) [<7f130204>] (can_fill_info [can_dev]) [<80693bc0>] (rtnl_fill_ifinfo) [<806949ec>] (rtnl_dump_ifinfo) [<806b4834>] (netlink_dump) [<806b4bc8>] (netlink_recvmsg) [<8065f180>] (sock_recvmsg) [<80660f90>] (___sys_recvmsg) [<80661e7c>] (__sys_recvmsg) [<80661ec0>] (SyS_recvmsg) [<80108b20>] (ret_fast_syscall+0x0/0x1c) agetty listens to netlink messages in order to update the login prompt when IP addresses change (if /etc/issue contains \4 or \6 escape codes): https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=e36deb6424e8 It's a useful feature, though it seems questionable that it causes CAN bit error statistics to be queried. Be that as it may, if hi3110_get_berr_counter() is invoked while a frame is sent by hi3110_hw_tx(), bogus SPI transfers like the following may occur: => 12 00 (hi3110_get_berr_counter() wanted to transmit EC 00 to query the transmit error counter, but the first byte was overwritten by hi3110_hw_tx_frame()) => EA 00 3E 80 01 FB (hi3110_hw_tx_frame() wanted to transmit a frame, but the first byte was overwritten by hi3110_get_berr_counter() because it wanted to query the receive error counter) This sequence hangs the transmission because the driver believes it has sent a frame and waits for the interrupt signaling completion, but in reality the chip has never sent away the frame since the commands it received were malformed. Fix by acquiring the SPI lock in hi3110_get_berr_counter(). I've scrutinized the entire driver for further unlocked SPI accesses but found no others.

As a result of this, excessive power is drawn by some of the affected systems while in sleep states or off. Restore the device_may_wakeup() check in pci_enable_wake(), but make sure that the PCI bus type's runtime suspend callback will not call device_may_wakeup() which is about system wakeup from sleep and not about device wakeup from runtime suspend.

fc21854 Ilya Dryomov 04 May 2018, 14:57:31 UTC ceph: fix iov_iter issues in ceph_direct_read_write() dio_get_pagev_size() and dio_get_pages_alloc() introduced in commit b5b98989dc7e ("ceph: combine as many iovec as possile into one OSD request") assume that the passed iov_iter is ITER_IOVEC. This isn't the case with splice where it ends up poking into the guts of ITER_BVEC or ITER_PIPE iterators, causing lockups and crashes easily reproduced with generic/095. Rather than trying to figure out gap alignment and stuff pages into a page vector, add a helper for going from iov_iter to a bio_vec array and make use of the new CEPH_OSD_DATA_TYPE_BVECS code.
