BugLink: http://bugs.launchpad.net/bugs/1642572 commit 89a28483 upstream. On 4.0, we saw a stack corruption from a page fault entering direct memory cgroup reclaim, calling into btrfs_releasepage(), which then tried to allocate an extent and recursed back into a kmem charge ad nauseam: [...] btrfs_releasepage+0x2c/0x30 try_to_release_page+0x32/0x50 shrink_page_list+0x6da/0x7a0 shrink_inactive_list+0x1e5/0x510 shrink_lruvec+0x605/0x7f0 shrink_zone+0xee/0x320 do_try_to_free_pages+0x174/0x440 try_to_free_mem_cgroup_pages+0xa7/0x130 try_charge+0x17b/0x830 memcg_charge_kmem+0x40/0x80 new_slab+0x2d9/0x5a0 __slab_alloc+0x2fd/0x44f kmem_cache_alloc+0x193/0x1e0 alloc_extent_state+0x21/0xc0 __clear_extent_bit+0x2b5/0x400 try_release_extent_mapping+0x1a3/0x220 __btrfs_releasepage+0x31/0x70 btrfs_releasepage+0x2c/0x30 try_to_release_page+0x32/0x50 shrink_page_list+0x6da/0x7a0 shrink_inactive_list+0x1e5/0x510 shrink_lruvec+0x605/0x7f0 shrink_zone+0xee/0x320 do_try_to_free_pages+0x174/0x440 try_to_free_mem_cgroup_pages+0xa7/0x130 try_charge+0x17b/0x830 mem_cgroup_try_charge+0x65/0x1c0 handle_mm_fault+0x117f/0x1510 __do_page_fault+0x177/0x420 do_page_fault+0xc/0x10 page_fault+0x22/0x30 On later kernels, kmem charging is opt-in rather than opt-out, and that particular kmem allocation in btrfs_releasepage() is no longer being charged and won't recurse and overrun the stack anymore. But it's not impossible for an accounted allocation to happen from the memcg direct reclaim context, and we needed to reproduce this crash many times before we even got a useful stack trace out of it. Like other direct reclaimers, mark tasks in memcg reclaim PF_MEMALLOC to avoid recursing into any other form of direct reclaim. Then let recursive charges from PF_MEMALLOC contexts bypass the cgroup limit. Link: http://lkml.kernel.org/r/20161025141050.GA13019@cmpxchg.orgSigned-off-by:

BugLink: http://bugs.launchpad.net/bugs/1642572 commit 1bc11d70 upstream. As described in https://bugzilla.kernel.org/show_bug.cgi?id=177821: After some analysis it seems to be that the problem is in alloc_super(). In case list_lru_init_memcg() fails it goes into destroy_super(), which calls list_lru_destroy(). And in list_lru_init() we see that in case memcg_init_list_lru() fails, lru->node is freed, but not set NULL, which then leads list_lru_destroy() to believe it is initialized and call memcg_destroy_list_lru(). memcg_destroy_list_lru() in turn can access lru->node[i].memcg_lrus, which is NULL.

BugLink: http://bugs.launchpad.net/bugs/1642572 commit 21753583 upstream. Back in commit f56141e3 ("all arches, signal: move restart_block to struct task_struct"), all architectures and core code were changed to use task_struct::restart_block. However, when h8300 support was subsequently restored in v4.2, it was not updated to account for this, and maintains thread_info::restart_block, which is not kept in sync. This patch drops the redundant restart_block from thread_info, and moves h8300 to the common one in task_struct, ensuring that syscall restarting always works as expected.

BugLink: http://bugs.launchpad.net/bugs/1642572 commit 36e3fa6a upstream. The i2c adapter is only relevant for some peer device types, so let's clear the pdt if it's still the same as the old_pdt when we tear down the i2c adapter. I don't really like this design pattern of updating port->whatever before doing the accompanying changes and passing around old_whatever to figure stuff out. Would make much more sense to me to the pass the new value around and only update the port->whatever when things are consistent. But let's try to work with what we have right now. Quoting a follow-up from Ville: "And naturally I forgot to amend the commit message w.r.t. this guy [the change in drm_dp_destroy_port]. We don't really need to do this here, but I figured I'd try to be a bit more consistent by having it, just to avoid accidental mistakes if/when someone changes this stuff again later." v2: Clear port->pdt in the caller, if needed (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Carlos Santa <carlos.santa@intel.com> Cc: Kirill A.

BugLink: http://bugs.launchpad.net/bugs/1642572 commit 147b36d5 upstream. Race condition between registering an I2C device driver and deregistering an I2C adapter device which is assumed to manage that I2C device may lead to a NULL pointer dereference due to the uninitialized list head of driver clients. The root cause of the issue is that the I2C bus may know about the registered device driver and thus it is matched by bus_for_each_drv(), but the list of clients is not initialized and commonly it is NULL, because I2C device drivers define struct i2c_driver as static and clients field is expected to be initialized by I2C core: i2c_register_driver() i2c_del_adapter() driver_register() ... bus_add_driver() ... ... bus_for_each_drv(..., __process_removed_adapter) ... i2c_do_del_adapter() ... list_for_each_entry_safe(..., &driver->clients, ...) INIT_LIST_HEAD(&driver->clients); To solve the problem it is sufficient to do clients list head initialization before calling driver_register(). The problem was found while using an I2C device driver with a sluggish registration routine on a bus provided by a physically detachable I2C master controller, but practically the oops may be reproduced under the race between arbitraty I2C device driver registration and managing I2C bus device removal e.g. by unbinding the latter over sysfs: % echo 21a4000.i2c > /sys/bus/platform/drivers/imx-i2c/unbind Unable to handle kernel NULL pointer dereference at virtual address 00000000 Internal error: Oops: 17 [#1] SMP ARM CPU: 2 PID: 533 Comm: sh Not tainted 4.9.0-rc3+ #61 Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree) task: e5ada400 task.stack: e4936000 PC is at i2c_do_del_adapter+0x20/0xcc LR is at __process_removed_adapter+0x14/0x1c Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 35bd004a DAC: 00000051 Process sh (pid: 533, stack limit = 0xe4936210) Stack: (0xe4937d28 to 0xe4938000) Backtrace: [<c0667be0>] (i2c_do_del_adapter) from [<c0667cc0>] (__process_removed_adapter+0x14/0x1c) [<c0667cac>] (__process_removed_adapter) from [<c0516998>] (bus_for_each_drv+0x6c/0xa0) [<c051692c>] (bus_for_each_drv) from [<c06685ec>] (i2c_del_adapter+0xbc/0x284) [<c0668530>] (i2c_del_adapter) from [<bf0110ec>] (i2c_imx_remove+0x44/0x164 [i2c_imx]) [<bf0110a8>] (i2c_imx_remove [i2c_imx]) from [<c051a838>] (platform_drv_remove+0x2c/0x44) [<c051a80c>] (platform_drv_remove) from [<c05183d8>] (__device_release_driver+0x90/0x12c) [<c0518348>] (__device_release_driver) from [<c051849c>] (device_release_driver+0x28/0x34) [<c0518474>] (device_release_driver) from [<c0517150>] (unbind_store+0x80/0x104) [<c05170d0>] (unbind_store) from [<c0516520>] (drv_attr_store+0x28/0x34) [<c05164f8>] (drv_attr_store) from [<c0298acc>] (sysfs_kf_write+0x50/0x54) [<c0298a7c>] (sysfs_kf_write) from [<c029801c>] (kernfs_fop_write+0x100/0x214) [<c0297f1c>] (kernfs_fop_write) from [<c0220130>] (__vfs_write+0x34/0x120) [<c02200fc>] (__vfs_write) from [<c0221088>] (vfs_write+0xa8/0x170) [<c0220fe0>] (vfs_write) from [<c0221e74>] (SyS_write+0x4c/0xa8) [<c0221e28>] (SyS_write) from [<c0108a20>] (ret_fast_syscall+0x0/0x1c) Signed-off-by:

CAI Qian <caiqian@redhat.com> pointed out that the semantics of shared subtrees make it possible to create an exponentially increasing number of mounts in a mount namespace. mkdir /tmp/1 /tmp/2 mount --make-rshared / for i in $(seq 1 20) ; do mount --bind /tmp/1 /tmp/2 ; done Will create create 2^20 or 1048576 mounts, which is a practical problem as some people have managed to hit this by accident. As such CVE-2016-6213 was assigned. Ian Kent <raven@themaw.net> described the situation for autofs users as follows: > The number of mounts for direct mount maps is usually not very large because of > the way they are implemented, large direct mount maps can have performance > problems. There can be anywhere from a few (likely case a few hundred) to less > than 10000, plus mounts that have been triggered and not yet expired. > > Indirect mounts have one autofs mount at the root plus the number of mounts that > have been triggered and not yet expired. > > The number of autofs indirect map entries can range from a few to the common > case of several thousand and in rare cases up to between 30000 and 50000. I've > not heard of people with maps larger than 50000 entries. > > The larger the number of map entries the greater the possibility for a large > number of active mounts so it's not hard to expect cases of a 1000 or somewhat > more active mounts. So I am setting the default number of mounts allowed per mount namespace at 100,000. This is more than enough for any use case I know of, but small enough to quickly stop an exponential increase in mounts. Which should be perfect to catch misconfigurations and malfunctioning programs. For anyone who needs a higher limit this can be changed by writing to the new /proc/sys/fs/mount-max sysctl.

When a buffer is being dequeued using VIDIOC_DQBUF IOCTL, the exact buffer which will be dequeued is not known until the buffer has been removed from the queue. The number of planes is specific to a buffer, not to the queue. This does lead to the situation where multi-plane buffers may be requested and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument struct with fewer planes. __fill_v4l2_buffer() however uses the number of planes from the dequeued videobuf2 buffer, overwriting kernel memory (the m.planes array allocated in video_usercopy() in v4l2-ioctl.c) if the user provided fewer planes than the dequeued buffer had.

BugLink: http://bugs.launchpad.net/bugs/1634545 The goal of the patch is to fix this scenario: ip link add dummy1 type dummy ip link set dummy1 up ip link set lo down ; ip link set lo up After that sequence, the local route to the link layer address of dummy1 is not there anymore. When the loopback is set down, all local routes are deleted by addrconf_ifdown()/rt6_ifdown(). At this time, the rt6_info entry still exists, because the corresponding idev has a reference on it. After the rcu grace period, dst_rcu_free() is called, and thus ___dst_free(), which will set obsolete to DST_OBSOLETE_DEAD. In this case, init_loopback() is called before dst_rcu_free(), thus obsolete is still sets to something <= 0. So, the function doesn't add the route again. To avoid that race, let's check the rt6 refcnt instead. Fixes: 25fb6ca4 ("net IPv6 : Fix broken IPv6 routing table after loopback down-up") Fixes: a881ae1f ("ipv6: don't call addrconf_dst_alloc again when enable lo") Fixes: 33d99113 ("ipv6: reallocate addrconf router for ipv6 address when lo device up") Reported-by:

BugLink: http://bugs.launchpad.net/bugs/1633404 Nothing prevents a new auditd starting up and replacing a valid audit_pid when an old auditd is still running, effectively starving out the old auditd since audit_pid no longer points to the old valid auditd. If no message to auditd has been attempted since auditd died unnaturally or got killed, audit_pid will still indicate it is alive. There isn't an easy way to detect if an old auditd is still running on the existing audit_pid other than attempting to send a message to see if it fails. An -ECONNREFUSED almost certainly means it disappeared and can be replaced. Other errors are not so straightforward and may indicate transient problems that will resolve themselves and the old auditd will recover. Yet others will likely need manual intervention for which a new auditd will not solve the problem. Send a new message type (AUDIT_REPLACE) to the old auditd containing a u32 with the PID of the new auditd. If the audit replace message succeeds (or doesn't fail with certainty), fail to register the new auditd and return an error (-EEXIST). This is expected to make the patch preventing an old auditd orphaning a new auditd redundant. V3: Switch audit message type from 1000 to 1300 block. Signed-off-by:

CVE-2016-8655 BugLink: http://bugs.launchpad.net/bugs/1646318 When packet_set_ring creates a ring buffer it will initialize a struct timer_list if the packet version is TPACKET_V3. This value can then be raced by a different thread calling setsockopt to set the version to TPACKET_V1 before packet_set_ring has finished. This leads to a use-after-free on a function pointer in the struct timer_list when the socket is closed as the previously initialized timer will not be deleted. The bug is fixed by taking lock_sock(sk) in packet_setsockopt when changing the packet version while also taking the lock at the start of packet_set_ring.
