4becb7ee5b ("net/x25: Fix x25_neigh refcnt leak when x25 .."): [ 89.261843] BUG: kernel NULL pointer dereference, address: 00000074

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master commit 4becb7ee5b3d2829ed7b9261a245a77d5b7de902 Author: Xiyu Yang <xiyuyang19(a)fudan.edu.cn> AuthorDate: Sat Apr 25 21:06:25 2020 +0800 Commit: David S. Miller <davem(a)davemloft.net> CommitDate: Mon Apr 27 11:20:30 2020 -0700 net/x25: Fix x25_neigh refcnt leak when x25 disconnect x25_connect() invokes x25_get_neigh(), which returns a reference of the specified x25_neigh object to "x25->neighbour" with increased refcnt. When x25 connect success and returns, the reference still be hold by "x25->neighbour", so the refcount should be decreased in x25_disconnect() to keep refcount balanced. The reference counting issue happens in x25_disconnect(), which forgets to decrease the refcnt increased by x25_get_neigh() in x25_connect(), causing a refcnt leak. Fix this issue by calling x25_neigh_put() before x25_disconnect() returns. Signed-off-by: Xiyu Yang <xiyuyang19(a)fudan.edu.cn> Signed-off-by: Xin Tan <tanxin.ctf(a)gmail.com> Signed-off-by: David S.

I'm not entirely sure that's the case. This report still points at the old commit fa6726c1e7 which has: + depends on ARCH_HAS_DEBUG_VM_PGTABLE || EXPERT + default n if !ARCH_HAS_DEBUG_VM_PGTABLE + default y if DEBUG_VM In -next we now have commit 647d9a0de34c and subsequently modified by commit 0a8646638865. So hopefully with the latest -next tree we won't see this report. We could as well remove the 'depends on ... || EXPERT' part but I'd rather leave this around with a default n (as in current -next) in case others want to have a go. If that's still causing problems, we can remove the '|| EXPERT' part, so there won't be any further regressions. -- Catalin

7322464a68 ("nsproxy: attach to namespaces via pidfds"): WARNING: CPU: 0 PID: 808 at lib/refcount.c:25 refcount_warn_saturate

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/0day-ci/linux/commits/Christian-Brauner/nsproxy-attach... commit 7322464a68c444dccde385b3b696f48e6d1bb5cc Author: Christian Brauner <christian.brauner(a)ubuntu.com> AuthorDate: Mon Apr 27 16:36:46 2020 +0200 Commit: 0day robot <lkp(a)intel.com> CommitDate: Tue Apr 28 08:20:37 2020 +0800 nsproxy: attach to namespaces via pidfds For quite a while we have been thinking about using pidfds to attach to namespaces. This patchset has existed for about a year already but we've wanted to wait to see how the general api would be received and adopted. Now that more and more programs in userspace have started using pidfds for process management it's time to send this one out. This patch makes it possible to use pidfds to attach to the namespaces of another process, i.e. they can be passed as the first argument to the setns() syscall. When only a single namespace type is specified the semantics are equivalent to passing an nsfd. That means setns(nsfd, CLONE_NEWNET) equals setns(pidfd, CLONE_NEWNET). However, when a pidfd is passed, multiple namespace flags can be specified in the second setns() argument and setns() will attach the caller to all the specified namespaces all at once or to none of them. If 0 is specified together with a pidfd then setns() will interpret it the same way 0 is interpreted together with a nsfd argument, i.e. attach to any/all namespaces. The obvious example where this is useful is a standard container manager interacting with a running container: pushing and pulling files or directories, injecting mounts, attaching/execing any kind of process, managing network devices all these operations require attaching to all or at least multiple namespaces at the same time. Given that nowadays most containers are spawned with all namespaces enabled we're currently looking at at least 14 syscalls, 7 to open the /proc/<pid>/ns/<ns> nsfds, another 7 to actually perform the namespace switch. With time namespaces we're looking at about 16 syscalls. (We could amortize the first 7 or 8 syscalls for opening the nsfds by stashing them in each container's monitor process but that would mean we need to send around those file descriptors through unix sockets everytime we want to interact with the container or keep on-disk state. Even in scenarios where a caller wants to join a particular namespace in a particular order callers still profit from batching other namespaces. That mostly applies to the user namespace but all container runtimes I found join the user namespace first no matter if it privileges or deprivileges the container.) With pidfds this becomes a single syscall no matter how many namespaces are supposed to be attached to. A decently designed, large-scale container manager usually isn't the parent of any of the containers it spawns so the containers don't die when it crashes or needs to update or reinitialize. This means that for the manger to interact with containers through pids is inherently racy especially on systems where the maximum pid number is not signficianly bumped. This is even more problematic since we often spawn and manage thousands or ten-thousands of containers. Interacting with a container through a pid thus can become risky quite quickly. Especially since we allow for an administrator to enable advanced features such as syscall interception where we're performing syscalls in lieu of the container. In all of those cases we use pidfds if they are available and we pass them around as stable references. Using them to setns() to the target process namespaces is as reliable as using nsfds. Either the target process is already dead and we get ESRCH or we manage to attach to its namespaces but we can't accidently attach to another process' namespaces. So pidfds lend themselves to be used with this api. Apart from significiantly reducing the number of syscalls from double digit to single digit which is a decent reason post-spectre/meltdown this also allows to switch to a set of namespaces atomically, i.e. either attaching to all the specified namespaces succeeds or we fail. If we fail we haven't changed a single namespace. There are currently three namespaces that can fail (other than for ENOMEM which really is not very interesting since we then have other problems anyway) for non-trivial reasons, user, mount, and pid namespaces. We can fail to attach to a pid namespace if it is not our current active pid namespace or a descendant of it. We can fail to attach to a user namespace because we are multi-threaded, because our current mount namespace shares filesystem state with other tasks, or because we're trying to setns() to the same user namespace, i.e. the target task has the same user namespace as we do. We can fail to attach to a mount namespace because it shares filesystem state with other tasks or because we fail to lookup the new root for the new mount namespace. In most non-pathological scenarios these issues can be somewhat mitigated. But there's e.g. still an inherent race between trying to setns() to the mount namespace of a task and that task spawning a child with CLONE_FS. If that process runs in a new user namespace we must have already setns()ed into the new user namespace otherwise we fail to attach to the mount namespace. There are other cases similar to that and we've had issues where we're half-attached to some namespace and failing in the middle. I've talked about some of these problem during the hallway track (something only the pre-COVID-19 generation will remember) of Plumber in Los Angeles in 2018(?). Even if all these issues could be avoided with super careful userspace coding it would be nicer to have this done in-kernel. There's not a lot of cost associated with this extension for the kernel and pidfds seem to lend themselves nicely for this. Cc: Eric W.
