commit 5deeb5ce upstream. When task->comm is passed directly to audit_log_untrustedstring() without getting a copy or using the task_lock, there is a race that could happen that would output a NULL (\0) in the middle of the output string that would effectively truncate the rest of the report text after the comm= field in the audit log message, losing fields. Using get_task_comm() to get a copy while acquiring the task_lock to prevent this and to prevent the result from being a mixture of old and new values of comm would incur potentially unacceptable overhead, considering that the value can be influenced by userspace and therefore untrusted anyways. Copy the value before passing it to audit_log_untrustedstring() ensures that a local copy is used to calculate the length *and* subsequently printed. Even if this value contains a mix of old and new values, it will only calculate and copy up to the first NULL, preventing the rest of the audit log message being truncated. Use a second local copy of comm to avoid a race between the first and second calls to audit_log_untrustedstring() with comm. Reported-by:

commit 35f71bc0 upstream. copy_process will report any failure in alloc_pid as ENOMEM currently which is misleading because the pid allocation might fail not only when the memory is short but also when the pid space is consumed already. The current man page even mentions this case: : EAGAIN : : A system-imposed limit on the number of threads was encountered. : There are a number of limits that may trigger this error: the : RLIMIT_NPROC soft resource limit (set via setrlimit(2)), which : limits the number of processes and threads for a real user ID, was : reached; the kernel's system-wide limit on the number of processes : and threads, /proc/sys/kernel/threads-max, was reached (see : proc(5)); or the maximum number of PIDs, /proc/sys/kernel/pid_max, : was reached (see proc(5)). so the current behavior is also incorrect wrt. documentation. POSIX man page also suggest returing EAGAIN when the process count limit is reached. This patch simply propagates error code from alloc_pid and makes sure we return -EAGAIN due to reservation failure. This will make behavior of fork closer to both our documentation and POSIX. alloc_pid might alsoo fail when the reaper in the pid namespace is dead (the namespace basically disallows all new processes) and there is no good error code which would match documented ones. We have traditionally returned ENOMEM for this case which is misleading as well but as per Eric W. Biederman this behavior is documented in man pid_namespaces(7) : If the "init" process of a PID namespace terminates, the kernel : terminates all of the processes in the namespace via a SIGKILL signal. : This behavior reflects the fact that the "init" process is essential for : the correct operation of a PID namespace. In this case, a subsequent : fork(2) into this PID namespace will fail with the error ENOMEM; it is : not possible to create a new processes in a PID namespace whose "init" : process has terminated. and introducing a new error code would be too risky so let's stick to ENOMEM for this case.

[ Upstream commit 31a41898 ] When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.

[ Upstream commit beb39db5 ] We have two problems in UDP stack related to bogus checksums : 1) We return -EAGAIN to application even if receive queue is not empty. This breaks applications using edge trigger epoll() 2) Under UDP flood, we can loop forever without yielding to other processes, potentially hanging the host, especially on non SMP. This patch is an attempt to make things better. We might in the future add extra support for rt applications wanting to better control time spent doing a recv() in a hostile environment. For example we could validate checksums before queuing packets in socket receive queue. Signed-off-by:

[ Upstream commit 47cc84ce ] When more than a multicast address is present in a MLDv2 report, all but the first address is ignored, because the code breaks out of the loop if there has not been an error adding that address. This has caused failures when two guests connected through the bridge tried to communicate using IPv6. Neighbor discoveries would not be transmitted to the other guest when both used a link-local address and a static address. This only happens when there is a MLDv2 querier in the network. The fix will only break out of the loop when there is a failure adding a multicast address.

[ Upstream commit 381c759d ] ip_error does not check if in_dev is NULL before dereferencing it. IThe following sequence of calls is possible: CPU A CPU B ip_rcv_finish ip_route_input_noref() ip_route_input_slow() inetdev_destroy() dst_input() With the result that a network device can be destroyed while processing an input packet. A crash was triggered with only unicast packets in flight, and forwarding enabled on the only network device. The error condition was created by the removal of the network device. As such it is likely the that error code was -EHOSTUNREACH, and the action taken by ip_error (if in_dev had been accessible) would have been to not increment any counters and to have tried and likely failed to send an icmp error as the network device is going away. Therefore handle this weird case by just dropping the packet if !in_dev. It will result in dropping the packet sooner, and will not result in an actual change of behavior.

[ Upstream commit 3f7352bf ] x86 has variable length encoding. x86 JIT compiler is trying to pick the shortest encoding for given bpf instruction. While doing so the jump targets are changing, so JIT is doing multiple passes over the program. Typical program needs 3 passes. Some very short programs converge with 2 passes. Large programs may need 4 or 5. But specially crafted bpf programs may hit the pass limit and if the program converges on the last iteration the JIT compiler will be producing an image full of 'int 3' insns. Fix this corner case by doing final iteration over bpf program. Fixes: 0a14842f ("net: filter: Just In Time compiler for x86-64") Reported-by:

commit 97b0b6ca upstream. If command line use EXTRA_CFLAGS (e.g. "EXTRA_CFLAGS=-mmedium-calls" for arc architecture, with allmodconfig), it can not pass compiling, the related error: drivers/staging/rtl8188eu/core/rtw_ap.c:22:27: fatal error: osdep_service.h: No such file or directory Signed-off-by:

commit 6319c61a upstream. Normally, the macros from command line are system specific macros (e.g __linux, __KERNEL__ ...), and module own macros are usually defined in their header files. DG_NAME and DG_PART are driver 'dgap' owned macros which are used by multiple files within driver, and need be defined in the driver main header file. So move DG_NAME and DG_PART to "dgap_driver.h", it not only can make code clearer, but also can avoid compiling failure when EXTRA_CFLAGS appended to make command line (e.g. "EXTRA_CFLAGS=-W").
