It its possible to configure your PAM stack to refuse login if audit messages (about the login) were unable to be sent. This is common in many distros and thus normal configuration of many containers. The PAM modules determine if audit is enabled/disabled in the kernel based on the return value from sending an audit message on the netlink socket. If userspace gets back ECONNREFUSED it believes audit is disabled in the kernel. If it gets any other error else it refuses to let the login proceed. Just about ever since the introduction of namespaces the kernel audit subsystem has returned EPERM if the task sending a message was not in the init user or pid namespace. So many forms of containers have never worked if audit was enabled in the kernel. BUT if the container was not in net_init then the kernel network code would send ECONNREFUSED (instead of the audit code sending EPERM). Thus by pure accident/dumb luck/bug if an admin configured the PAM stack to reject all logins that didn't talk to audit, but then ran the login untility in the non-init_net namespace, it would work!! Clearly this was a bug, but it is a bug some people expected. With the introduction of network namespace support in 3.14-rc1 the two bugs stopped cancelling each other out. Now, containers in the non-init_net namespace refused to let users log in (just like PAM was configfured!) Obviously some people were not happy that what used to let users log in, now didn't! This fix is kinda hacky. We return ECONNREFUSED for all non-init relevant namespaces. That means that not only will the old broken non-init_net setups continue to work, now the broken non-init_pid or non-init_user setups will 'work'. They don't really work, since audit isn't logging things. But it's what most users want. In 3.15 we should have patches to support not only the non-init_net (3.14) namespace but also the non-init_pid and non-init_user namespace. So all will be right in the world. This just opens the doors wide open on 3.14 and hopefully makes users happy, if not the audit system...

由 Elias Vanderstuyft 提交于
If a new (id == -1) ff effect was uploaded from userspace, ff-core.c::input_ff_upload() will have assigned a positive number to the new effect id. Currently, evdev.c::evdev_do_ioctl() will save this new id to userspace, regardless of whether the upload succeeded or not. On upload failure, this can be confusing because the dev->ff->effects[] array will not contain an element at the index of that new effect id. This patch fixes this by leaving the id unchanged after upload fails. Note: Unfortunately applications should still expect changed effect id for quite some time. This has been discussed on: http://www.mail-archive.com/linux-input@vger.kernel.org/msg08513.html ("ff-core effect id handling in case of a failed effect upload") Suggested-by: NDmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: NElias Vanderstuyft <elias.vds@gmail.com> Signed-off-by: NDmitry Torokhov <dmitry.torokhov@gmail.com>

Olivier Bonvalet reported having repeated crashes due to a failed assertion he was hitting in rbd_img_obj_callback(): Assertion failure in rbd_img_obj_callback() at line 2165: rbd_assert(which >= img_request->next_completion); With a lot of help from Olivier with reproducing the problem we were able to determine the object and image requests had already been completed (and often freed) at the point the assertion failed. There was a great deal of discussion on the ceph-devel mailing list about this. The problem only arose when there were two (or more) object requests in an image request, and the problem was always seen when the second request was being completed. The problem is due to a race in the window between setting the "done" flag on an object request and checking the image request's next completion value. When the first object request completes, it checks to see if its successor request is marked "done", and if so, that request is also completed. In the process, the image request's next_completion value is updated to reflect that both the first and second requests are completed. By the time the second request is able to check the next_completion value, it has been set to a value *greater* than its own "which" value, which caused an assertion to fail. Fix this problem by skipping over any completion processing unless the completing object request is the next one expected. Test only for inequality (not >=), and eliminate the bad assertion.

When the vlan filtering is enabled on the bridge, but the filter is not configured on the bridge device itself, running tcpdump on the bridge device will result in a an Oops with NULL pointer dereference. The reason is that br_pass_frame_up() will bypass the vlan check because promisc flag is set. It will then try to get the table pointer and process the packet based on the table. Since the table pointer is NULL, we oops. Catch this special condition in br_handle_vlan().

skb_network_protocol() already accounts for multiple vlan headers that may be present in the skb. However, skb_mac_gso_segment() doesn't know anything about it and assumes that skb->mac_len is set correctly to skip all mac headers. That may not always be the case. If we are simply forwarding the packet (via bridge or macvtap), all vlan headers may not be accounted for. A simple solution is to allow skb_network_protocol to return the vlan depth it has calculated. This way skb_mac_gso_segment will correctly skip all mac headers.
