net/openvswitch/flow_netlink.c: In function ‘validate_and_copy_set_tun’: net/openvswitch/flow_netlink.c:1749: warning: ‘err’ may be used uninitialized in this function If ipv4_tun_from_nlattr() returns a different positive value than OVS_TUNNEL_KEY_ATTR_GENEVE_OPTS, err will be uninitialized, and validate_and_copy_set_tun() may return an undefined value instead of a zero success indicator.

When the RDS transport is TCP, we cannot inline the call to rds_send_xmit from rds_cong_queue_update because (a) we are already holding the sock_lock in the recv path, and will deadlock when tcp_setsockopt/tcp_sendmsg try to get the sock lock (b) cong_queue_update does an irqsave on the rds_cong_lock, and this will trigger warnings (for a good reason) from functions called out of sock_lock. This patch reverts the change introduced by 2fa57129 ("RDS: Bypass workqueue when queueing cong updates"). The patch has been verified for both RDS/TCP as well as RDS/RDMA to ensure that there are not regressions for either transport: - for verification of RDS/TCP a client-server unit-test was used, with the server blocked in gdb and thus unable to drain its rcvbuf, eventually triggering a RDS congestion update. - for RDS/RDMA, the standard IB regression tests were used Signed-off-by: NSowmini Varadhan <sowmini.varadhan@oracle.com> Signed-off-by: NDavid S.

This one was driving me mad, with several lines of warnings during the allmodconfig build for a single bogus pointer cast. The warning was so verbose due to the indirect macro expansion explanation, and the whole thing was just for a debug printout. The bogus pointer-to-integer cast was pointless anyway, so just remove it, and use '%p' to show the pointer. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The device indicates the result of a read/write operation by making the status available on a subsequent request from the driver. This is not ready immediately, though, so the driver is currently slamming the device with hundreds of pointless requests before getting the expected response. Add a two millisecond delay before each attempt. This is approximately the behavior observed with version 4.2.7.1 of the Windows driver.

Commit 1d10eb2f ("crypto: switch af_alg_make_sg() to iov_iter") broke af_alg_make_sg() and skcipher_recvmsg() in the process of moving them to the iov_iter interfaces. The 'npages' calculation in the formar calculated the number of *bytes* in the pages, and in the latter case the conversion didn't re-read the value of 'ctx->used' after waiting for it to become non-zero. This reverts to the original code for both these cases. Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: David Miller <davem@davemloft.net> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching由 Linus Torvalds 提交于
Pull live patching infrastructure from Jiri Kosina: "Let me provide a bit of history first, before describing what is in this pile. Originally, there was kSplice as a standalone project that implemented stop_machine()-based patching for the linux kernel. This project got later acquired, and the current owner is providing live patching as a proprietary service, without any intentions to have their implementation merged. Then, due to rising user/customer demand, both Red Hat and SUSE started working on their own implementation (not knowing about each other), and announced first versions roughly at the same time [1] [2]. The principle difference between the two solutions is how they are making sure that the patching is performed in a consistent way when it comes to different execution threads with respect to the semantic nature of the change that is being introduced. In a nutshell, kPatch is issuing stop_machine(), then looking at stacks of all existing processess, and if it decides that the system is in a state that can be patched safely, it proceeds insterting code redirection machinery to the patched functions. On the other hand, kGraft provides a per-thread consistency during one single pass of a process through the kernel and performs a lazy contignuous migration of threads from "unpatched" universe to the "patched" one at safe checkpoints. If interested in a more detailed discussion about the consistency models and its possible combinations, please see the thread that evolved around [3]. It pretty quickly became obvious to the interested parties that it's absolutely impractical in this case to have several isolated solutions for one task to co-exist in the kernel. During a dedicated Live Kernel Patching track at LPC in Dusseldorf, all the interested parties sat together and came up with a joint aproach that would work for both distro vendors. Steven Rostedt took notes [4] from this meeting. And the foundation for that aproach is what's present in this pull request. It provides a basic infrastructure for function "live patching" (i.e. code redirection), including API for kernel modules containing the actual patches, and API/ABI for userspace to be able to operate on the patches (look up what patches are applied, enable/disable them, etc). It's relatively simple and minimalistic, as it's making use of existing kernel infrastructure (namely ftrace) as much as possible. It's also self-contained, in a sense that it doesn't hook itself in any other kernel subsystem (it doesn't even touch any other code). It's now implemented for x86 only as a reference architecture, but support for powerpc, s390 and arm is already in the works (adding arch-specific support basically boils down to teaching ftrace about regs-saving). Once this common infrastructure gets merged, both Red Hat and SUSE have agreed to immediately start porting their current solutions on top of this, abandoning their out-of-tree code. The plan basically is that each patch will be marked by flag(s) that would indicate which consistency model it is willing to use (again, the details have been sketched out already in the thread at [3]). Before this happens, the current codebase can be used to patch a large group of secruity/stability problems the patches for which are not too complex (in a sense that they don't introduce non-trivial change of function's return value semantics, they don't change layout of data structures, etc) -- this corresponds to LEAVE_FUNCTION && SWITCH_FUNCTION semantics described at [3].

Commit 84683a7e ("sata_dwc_460ex: enable COMPILE_TEST for the driver") enabled this driver for non-ppc460-ex platforms, but it was then disabled for ARM and ARM64 by commit 2de5a9c0 ("sata_dwc_460ex: disable compilation on ARM and ARM64") because it's too noisy and broken. This disabled is entirely, because it's too noisy on x86-64 too, and there's no point in disabling architectures one by one. At a minimum, the code isn't 64-bit clean, and even on 32-bit it is questionable whether it makes sense.

Merge misc updates from Andrew Morton: "Bite-sized chunks this time, to avoid the MTA ratelimiting woes. - fs/notify updates - ocfs2 - some of MM" That laconic "some MM" is mainly the removal of remap_file_pages(), which is a big simplification of the VM, and which gets rid of a *lot* of random cruft and special cases because we no longer support the non-linear mappings that it used. From a user interface perspective, nothing has changed, because the remap_file_pages() syscall still exists, it's just done by emulating the old behavior by creating a lot of individual small mappings instead of one non-linear one. The emulation is slower than the old "native" non-linear mappings, but nobody really uses or cares about remap_file_pages(), and simplifying the VM is a big advantage. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (78 commits) memcg: zap memcg_slab_caches and memcg_slab_mutex memcg: zap memcg_name argument of memcg_create_kmem_cache memcg: zap __memcg_{charge,uncharge}_slab mm/page_alloc.c: place zone_id check before VM_BUG_ON_PAGE check mm: hugetlb: fix type of hugetlb_treat_as_movable variable mm, hugetlb: remove unnecessary lower bound on sysctl handlers"? mm: memory: merge shared-writable dirtying branches in do_wp_page() mm: memory: remove ->vm_file check on shared writable vmas xtensa: drop _PAGE_FILE and pte_file()-related helpers x86: drop _PAGE_FILE and pte_file()-related helpers unicore32: drop pte_file()-related helpers um: drop _PAGE_FILE and pte_file()-related helpers tile: drop pte_file()-related helpers sparc: drop pte_file()-related helpers sh: drop _PAGE_FILE and pte_file()-related helpers score: drop _PAGE_FILE and pte_file()-related helpers s390: drop pte_file()-related helpers parisc: drop _PAGE_FILE and pte_file()-related helpers openrisc: drop _PAGE_FILE and pte_file()-related helpers nios2: drop _PAGE_FILE and pte_file()-related helpers ...

Still, the majority of changes here are reworks of existing code to make it more straightforward or to prepare it for implementing new features on top of it. The primary example is the rework of ACPI resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with support for IOAPIC hotplug implemented on top of it, but there is quite a number of changes of this kind in the cpufreq core, ACPICA, ACPI EC driver, ACPI processor driver and the generic power domains core code too.

mem_cgroup->memcg_slab_caches is a list of kmem caches corresponding to the given cgroup. Currently, it is only used on css free in order to destroy all caches corresponding to the memory cgroup being freed. The list is protected by memcg_slab_mutex. The mutex is also used to protect kmem_cache->memcg_params->memcg_caches arrays and synchronizes kmem_cache_destroy vs memcg_unregister_all_caches. However, we can perfectly get on without these two. To destroy all caches corresponding to a memory cgroup, we can walk over the global list of kmem caches, slab_caches, and we can do all the synchronization stuff using the slab_mutex instead of the memcg_slab_mutex. This patch therefore gets rid of the memcg_slab_caches and memcg_slab_mutex. Apart from this nice cleanup, it also: - assures that rcu_barrier() is called once at max when a root cache is destroyed or a memory cgroup is freed, no matter how many caches have SLAB_DESTROY_BY_RCU flag set; - fixes the race between kmem_cache_destroy and kmem_cache_create that exists, because memcg_cleanup_cache_params, which is called from kmem_cache_destroy after checking that kmem_cache->refcount=0, releases the slab_mutex, which gives kmem_cache_create a chance to make an alias to a cache doomed to be destroyed.
