a7be67b Olof Johansson 15 May 2018, 20:49:55 UTC Merge tag 'davinci-fixes-for-v4.17-part-2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into fixes Second set of fixes for TI DaVinci. They are needed for DM6467 EVM to work. The first patch fixes an issue with timer interrupt and the second two are needed for video driver to probe successfully. * tag 'davinci-fixes-for-v4.17-part-2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: ARM: davinci: board-dm646x-evm: set VPIF capture card name ARM: davinci: board-dm646x-evm: pass correct I2C adapter id for VPIF ARM: davinci: dm646x: fix timer interrupt generation Signed-off-by: Olof Johansson <olof@lixom.net> 15 May 2018, 20:49:55 UTC
bb7298a Sekhar Nori 11 May 2018, 15:21:36 UTC ARM: davinci: board-dm646x-evm: set VPIF capture card name VPIF capture driver expects card name to be set since it uses it without checking for NULL. The commit which introduced VPIF display and capture support added card name only for display, not for capture. Set it in platform data to probe driver successfully. While at it, also fix the display card name to something more appropriate.

73d4337 Sekhar Nori 11 May 2018, 15:21:34 UTC ARM: davinci: dm646x: fix timer interrupt generation commit b38434145b34 ("ARM: davinci: irqs: Correct McASP1 TX interrupt definition for DM646x") inadvertently removed priority setting for timer0_12 (bottom half of timer0). This timer is used as clockevent. When INTPRIn register setting for an interrupt is left at 0, it is mapped to FIQ by the AINTC causing the timer interrupt to not get generated. Fix it by including an entry for timer0_12 in interrupt priority map array. While at it, move the clockevent comment to the right place.

9954b80 Russell King 10 May 2018, 13:24:20 UTC ARM: keystone: fix platform_domain_notifier array overrun platform_domain_notifier contains a variable sized array, which the pm_clk_notify() notifier treats as a NULL terminated array: for (con_id = clknb->con_ids; *con_id; con_id++) pm_clk_add(dev, *con_id); Omitting the initialiser for con_ids means that the array is zero sized, and there is no NULL terminator. This leads to pm_clk_notify() overrunning into what ever structure follows, which may not be NULL. This leads to an oops: Unable to handle kernel NULL pointer dereference at virtual address 0000008c pgd = c0003000 [0000008c] *pgd=80000800004003c, *pmd=00000000c Internal error: Oops: 206 [#1] PREEMPT SMP ARM Modules linked in:c CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.16.0+ #9 Hardware name: Keystone PC is at strlen+0x0/0x34 LR is at kstrdup+0x18/0x54 pc : [<c0623340>] lr : [<c0111d6c>] psr: 20000013 sp : eec73dc0 ip : eed780c0 fp : 00000001 r10: 00000000 r9 : 00000000 r8 : eed71e10 r7 : 0000008c r6 : 0000008c r5 : 014000c0 r4 : c03a6ff4 r3 : c09445d0 r2 : 00000000 r1 : 014000c0 r0 : 0000008c Flags: nzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 30c5387d Table: 00003000 DAC: fffffffd Process swapper/0 (pid: 1, stack limit = 0xeec72210) Stack: (0xeec73dc0 to 0xeec74000) ...

We could handle the problem in the R-Car DU LVDS DT backward compatibility code, but that fix would only be used for v4.17 as in v4.18 the Gen2 DT will move to the new LVDS DT bindings.

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

Part of them were fixed earlier in 919483096bfe. * udp_sendmsg one was there since the beginning when linux sources were first added to git; * ping_v4_sendmsg one was copy/pasted in c319b4d76b9e. Whenever return happens in udp_sendmsg() or ping_v4_sendmsg() IP options have to be freed if they were allocated previously.

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.

This is currently put back every time we receive a packet, but it isn't started when we first send a packet. Without this, the call may wait forever if the server doesn't deign to reply. Fix this by setting the timeout upon a successful UDP sendmsg call for the first DATA packet. The timeout is initiated only for initial transmission and not for subsequent retries as we don't want the retry mechanism to extend the timeout indefinitely.
