Cannot start container: no space left on device (cpuset cgroup) #133

I have this issue as well. The workaround is to run the following command before starting a Docker container: |
|
I think docker-archive/libcontainer#642 alread fixed it, you can try again after moby/moby#14693 is merged. |
|
Oh, I didn't see that PR. Pretty sure it fixes the problem. I'll try again when libcontainer is updated and reopen if I still have problems. Thanks! |
|
In the process of testing a backport of docker-archive/libcontainer#642 into docker 1.7.1 it seems the problem is not fully solved for me. If I reproduce the issue with a version of docker that includes the fix, docker will produce the same error. If I run docker again, the issue is then resolved until the next restart of the machine. I've found that both 1.7.1 (with backported fix) and 1.8.0-rc1 will behave identically in this regard. |

@pbx0 Is this problem still existed? Can you show the steps how you reproduce the issue? |
|
@alban 's patch did fix the kernel bug in 3.17+, @pbx0 if you are using kernel newer than 3.17, probably should merge that kernel fix and try again. |
|
@hqhq I can confirm alban's kernel patch fixed it for me. Forgot to come back here and say so. |

ipc,sem: fix use after free on IPC_RMID after a task using same semaphore set exits
[ Upstream commit 602b8593d2b4138c10e922eeaafe306f6b51817b ]
The current semaphore code allows a potential use after free: in
exit_sem we may free the task's sem_undo_list while there is still
another task looping through the same semaphore set and cleaning the
sem_undo list at freeary function (the task called IPC_RMID for the same
semaphore set).
For example, with a test program [1] running which keeps forking a lot
of processes (which then do a semop call with SEM_UNDO flag), and with
the parent right after removing the semaphore set with IPC_RMID, and a
kernel built with CONFIG_SLAB, CONFIG_SLAB_DEBUG and
CONFIG_DEBUG_SPINLOCK, you can easily see something like the following
in the kernel log:

Kernel panic - not syncing: softlockup: hung tasks
I wasn't able to trigger any badness on a recent kernel without the
proper config debugs enabled, however I have softlockup reports on some
kernel versions, in the semaphore code, which are similar as above (the
scenario is seen on some servers running IBM DB2 which uses semaphore
syscalls).
The patch here fixes the race against freeary, by acquiring or waiting
on the sem_undo_list lock as necessary (exit_sem can race with freeary,
while freeary sets un->semid to -1 and removes the same sem_undo from
list_proc or when it removes the last sem_undo).
After the patch I'm unable to reproduce the problem using the test case

ipc/sem.c: update/correct memory barriers
[ Upstream commit 3ed1f8a99d70ea1cd1508910eb107d0edcae5009 ]
sem_lock() did not properly pair memory barriers:
!spin_is_locked() and spin_unlock_wait() are both only control barriers.
The code needs an acquire barrier, otherwise the cpu might perform read
operations before the lock test.
As no primitive exists inside <include/spinlock.h> and since it seems
noone wants another primitive, the code creates a local primitive within
ipc/sem.c.
With regards to -stable:
The change of sem_wait_array() is a bugfix, the change to sem_lock() is a
nop (just a preprocessor redefinition to improve the readability). The
bugfix is necessary for all kernels that use sem_wait_array() (i.e.:
starting from 3.10).

mm: hugetlb: introduce page_huge_active
[ Upstream commit bcc54222309c70ebcb6c69c156fba4a13dee0a3b ]
We are not safe from calling isolate_huge_page() on a hugepage
concurrently, which can make the victim hugepage in invalid state and
results in BUG_ON().
The root problem of this is that we don't have any information on struct
page (so easily accessible) about hugepages' activeness. Note that
hugepages' activeness means just being linked to
hstate->hugepage_activelist, which is not the same as normal pages'
activeness represented by PageActive flag.
Normal pages are isolated by isolate_lru_page() which prechecks PageLRU
before isolation, so let's do similarly for hugetlb with a new
paeg_huge_active().
set/clear_page_huge_active() should be called within hugetlb_lock. But
hugetlb_cow() and hugetlb_no_page() don't do this, being justified because
in these functions set_page_huge_active() is called right after the
hugepage is allocated and no other thread tries to isolate it.

Hugetlbfs pages will get a refcount in get_any_page() or

We should consider info->feature_persistent when adding indirect page to list
info->indirect_pages, else the BUG_ON() in blkif_free() would be triggered.
When we are using persistent grants the indirect_pages list
should always be empty because blkfront has pre-allocated enough
persistent pages to fill all requests on the ring.

The BUG_ON() in purge_persistent_gnt() will be triggered when previous purge
work haven't finished.
There is a work_pending() before this BUG_ON, but it doesn't account if the work
is still currently running.

perf: Fix fasync handling on inherited events
[ Upstream commit fed66e2cdd4f127a43fd11b8d92a99bdd429528c ]
Vince reported that the fasync signal stuff doesn't work proper for
inherited events. So fix that.
Installing fasync allocates memory and sets filp->f_flags |= FASYNC,
which upon the demise of the file descriptor ensures the allocation is
freed and state is updated.
Now for perf, we can have the events stick around for a while after the
original FD is dead because of references from child events. So we
cannot copy the fasync pointer around. We can however consistently use
the parent's fasync, as that will be updated.

drm/vmwgfx: Fix execbuf locking issues
[ Upstream commit 3e04e2fe6d87807d27521ad6ebb9e7919d628f25 ]
This addresses two issues that cause problems with viewperf maya-03 in
situation with memory pressure.
The first issue causes attempts to unreserve buffers if batched
reservation fails due to, for example, a signal pending. While previously
the ttm_eu api was resistant against this type of error, it is no longer
and the lockdep code will complain about attempting to unreserve buffers
that are not reserved. The issue is resolved by avoid calling
ttm_eu_backoff_reservation in the buffer reserve error path.
The second issue is that the binding_mutex may be held when user-space
fence objects are created and hence during memory reclaims. This may cause
recursive attempts to grab the binding mutex. The issue is resolved by not
holding the binding mutex across fence creation and submission.

mfd: arizona: Fix initialisation of the PM runtime
[ Upstream commit 72e43164fd472f6c2659c8313b87da962322dbcf ]
The PM runtime core by default assumes a chip is suspended when runtime
PM is enabled. Currently the arizona driver enables runtime PM when the
chip is fully active and then disables the DCVDD regulator at the end of
arizona_dev_init. This however has several problems, firstly the if we
reach the end of arizona_dev_init, we did not properly follow all the
proceedures for shutting down the chip, and most notably we never marked
the chip as cache only so any writes occurring between then and the next
PM runtime resume will be lost. Secondly, if we are already resumed when
we reach the end of dev_init, then at best we get unbalanced regulator
enable/disables at work we lose DCVDD whilst we need it.
Additionally, since the commit 4f0216409f7c ("mfd: arizona: Add better
support for system suspend"), the PM runtime operations may
disable/enable the IRQ, so the IRQs must now be enabled before we call
any PM operations.
This patch adds a call to pm_runtime_set_active to inform the PM core
that the device is starting up active and moves the PM enabling to
around the IRQ initialisation to avoid any PM callbacks happening until
the IRQs are initialised.

SCSI: Fix NULL pointer dereference in runtime PM
[ Upstream commit 49718f0fb8c9af192b33d8af3a2826db04025371 ]
The routines in scsi_rpm.c assume that if a runtime-PM callback is
invoked for a SCSI device, it can only mean that the device's driver
has asked the block layer to handle the runtime power management (by
calling blk_pm_runtime_init(), which among other things sets q->dev).
However, this assumption turns out to be wrong for things like the ses
driver. Normally ses devices are not allowed to do runtime PM, but
userspace can override this setting. If this happens, the kernel gets
a NULL pointer dereference when blk_post_runtime_resume() tries to use
the uninitialized q->dev pointer.
This patch fixes the problem by calling the block layer's runtime-PM
routines only if the device's driver really does have a runtime-PM
callback routine. Since ses doesn't define any such callbacks, the
crash won't occur.
This fixes Bugzilla #101371.

x86/nmi/64: Switch stacks on userspace NMI entry
[ Upstream commit 9b6e6a8334d56354853f9c255d1395c2ba570e0a ]
Returning to userspace is tricky: IRET can fail, and ESPFIX can
rearrange the stack prior to IRET.
The NMI nesting fixup relies on a precise stack layout and
atomic IRET. Rather than trying to teach the NMI nesting fixup
to handle ESPFIX and failed IRET, punt: run NMIs that came from
user mode on the normal kernel stack.
This will make some nested NMIs visible to C code, but the C
code is okay with that.
As a side effect, this should speed up perf: it eliminates an
RDMSR when NMIs come from user mode.

rcu: Move lockless_dereference() out of rcupdate.h
[ Upstream commit 0a04b0166929405cd833c1cc40f99e862b965ddc ]
I want to use lockless_dereference() from seqlock.h, which would mean
including rcupdate.h from it, however rcupdate.h already includes
seqlock.h.
Avoid this by moving lockless_dereference() into compiler.h. This is
somewhat tricky since it uses smp_read_barrier_depends() which isn't
available there, but its a CPP macro so we can get away with it.
The alternative would be moving it into asm/barrier.h, but that would
be updating each arch (I can do if people feel that is more
appropriate).

modify_ldt() has questionable locking and does not synchronize

threads' LDTs using an IPI on all modifications.
This will dramatically slow down modify_ldt in multithreaded

care about modify_ldt's performance in the first place.

mfd: lpc_ich: Assign subdevice ids automatically
[ Upstream commit 1abf25a25b86dcfe28d243a5af71bd1c9d6de1ef ]
Using -1 as platform device id means that the platform driver core will not
assign any id to the device (the device name will not have id at all). This
results problems on systems that have multiple PCHs (Platform Controller
HUBs) because all of them also include their own copy of LPC device.
All the subsequent device creations will fail because there already exists
platform device with the same name.
Fix this by passing PLATFORM_DEVID_AUTO as platform device id. This makes
the platform device core to allocate new ids automatically.

net/tipc: initialize security state for new connection socket

This was due to a failure to initialize the security state of the new
connection sock by the tipc code, leaving it with junk in the security
class field and an unlabeled secid. Add a call to security_sk_clone()
to inherit the security state from the parent socket.

bridge: mdb: zero out the local br_ip variable before use
[ Upstream commit f1158b74e54f2e2462ba5e2f45a118246d9d5b43 ]
Since commit b0e9a30dd669 ("bridge: Add vlan id to multicast groups")
there's a check in br_ip_equal() for a matching vlan id, but the mdb
functions were not modified to use (or at least zero it) so when an
entry was added it would have a garbage vlan id (from the local br_ip
variable in __br_mdb_add/del) and this would prevent it from being
matched and also deleted. So zero out the whole local ip var to protect
ourselves from future changes and also to fix the current bug, since
there's no vlan id support in the mdb uapi - use always vlan id 0.
Example before patch:

net: do not process device backlog during unregistration
[ Upstream commit e9e4dd3267d0c5234c5c0f47440456b10875dec9 ]
commit 381c759d9916 ("ipv4: Avoid crashing in ip_error")
fixes a problem where processed packet comes from device
with destroyed inetdev (dev->ip_ptr). This is not expected
because inetdev_destroy is called in NETDEV_UNREGISTER
phase and packets should not be processed after
dev_close_many() and synchronize_net(). Above fix is still
required because inetdev_destroy can be called for other
reasons. But it shows the real problem: backlog can keep
packets for long time and they do not hold reference to
device. Such packets are then delivered to upper levels
at the same time when device is unregistered.
Calling flush_backlog after NETDEV_UNREGISTER_FINAL still
accounts all packets from backlog but before that some packets
continue to be delivered to upper levels long after the
synchronize_net call which is supposed to wait the last
ones. Also, as Eric pointed out, processed packets, mostly
from other devices, can continue to add new packets to backlog.
Fix the problem by moving flush_backlog early, after the
device driver is stopped and before the synchronize_net() call.
Then use netif_running check to make sure we do not add more
packets to backlog. We have to do it in enqueue_to_backlog
context when the local IRQ is disabled. As result, after the
flush_backlog and synchronize_net sequence all packets
should be accounted.
Thanks to Eric W. Biederman for the test script and his
valuable feedback!

net: Fix skb csum races when peeking
[ Upstream commit 89c22d8c3b278212eef6a8cc66b570bc840a6f5a ]
When we calculate the checksum on the recv path, we store the
result in the skb as an optimisation in case we need the checksum
again down the line.
This is in fact bogus for the MSG_PEEK case as this is done without
any locking. So multiple threads can peek and then store the result
to the same skb, potentially resulting in bogus skb states.
This patch fixes this by only storing the result if the skb is not
shared. This preserves the optimisations for the few cases where
it can be done safely due to locking or other reasons, e.g., SIOCINQ.

isdn/gigaset: reset tty->receive_room when attaching ser_gigaset

Commit 79901317ce80 ("n_tty: Don't flush buffer when closing ldisc"),
first merged in kernel release 3.10, caused the following regression
in the Gigaset M101 driver:
Before that commit, when closing the N_TTY line discipline in
preparation to switching to N_GIGASET_M101, receive_room would be
reset to a non-zero value by the call to n_tty_flush_buffer() in
n_tty's close method. With the removal of that call, receive_room
might be left at zero, blocking data reception on the serial line.
The present patch fixes that regression by setting receive_room
to an appropriate value in the ldisc open method.

Thus remove the proc entry manually if bond_release_and_destroy() is
used. Because of the checks in bond_remove_proc_entry() it's not a
problem for a bond device to change namespaces (the bug fixed by the
Fixes commit) but since commit
f9399814927ad ("bonding: Don't allow bond devices to change network
namespaces.") that can't happen anyway.

bonding: correct the MAC address for "follow" fail_over_mac policy
[ Upstream commit a951bc1e6ba58f11df5ed5ddc41311e10f5fd20b ]
The "follow" fail_over_mac policy is useful for multiport devices that
either become confused or incur a performance penalty when multiple
ports are programmed with the same MAC address, but the same MAC
address still may happened by this steps for this policy:
1) echo +eth0 > /sys/class/net/bond0/bonding/slaves
bond0 has the same mac address with eth0, it is MAC1.
2) echo +eth1 > /sys/class/net/bond0/bonding/slaves
eth1 is backup, eth1 has MAC2.
3) ifconfig eth0 down
eth1 became active slave, bond will swap MAC for eth0 and eth1,
so eth1 has MAC1, and eth0 has MAC2.
4) ifconfig eth1 down
there is no active slave, and eth1 still has MAC1, eth2 has MAC2.
5) ifconfig eth0 up
the eth0 became active slave again, the bond set eth0 to MAC1.
Something wrong here, then if you set eth1 up, the eth0 and eth1 will have the same
MAC address, it will break this policy for ACTIVE_BACKUP mode.
This patch will fix this problem by finding the old active slave and
swap them MAC address before change active slave.

inet: frags: fix defragmented packet's IP header for af_packet
[ Upstream commit 0848f6428ba3a2e42db124d41ac6f548655735bf ]
When ip_frag_queue() computes positions, it assumes that the passed
sk_buff does not contain L2 headers.
However, when PACKET_FANOUT_FLAG_DEFRAG is used, IP reassembly
functions can be called on outgoing packets that contain L2 headers.
Also, IPv4 checksum is not corrected after reassembly.

I was occasionally getting this error when running docker:
After investigating a bit I found the cause of the problem.
I get this error because
cpuset.memsin the container's cpuset cgroup directory is empty. In that case, libcontainer sets that file to the value of the parent and does this recursively until it finds an existing parent.An example might be easier to understand, if the container's cpuset cgroup directory is
and the current existing directories are
libcontainer will start at
docker-ca65deb2d7972d5a1772023ad82d843bb639fcfea9d75e78e0f99fcad9e683ba.scope, go to the parent and then go one more level up tocpusetbecausesystem.slicedoesn't exist. Then it will set/sys/fs/cgroup/cpuset/system.slice/cpuset.memsto the value in/sys/fs/cgroup/cpuset/cpuset.memsand/sys/fs/cgroup/cpuset/system.slice/docker-ca65deb2d7972d5a1772023ad82d843bb639fcfea9d75e78e0f99fcad9e683ba.scope/cpuset.memsto that same value.This works fine when
/sys/fs/cgroup/system.slicedoesn't exist. But if it exists and has an empty value,/sys/fs/cgroup/cpuset/system.slice/docker-ca65deb2d7972d5a1772023ad82d843bb639fcfea9d75e78e0f99fcad9e683ba.scope/cpuset.memswill also end up with an empty value, causing the error.The solution could be keeping the recursion until you find the first non-empty value or you're out of the cpuset controller.
