2019-03-28RDMA/core: Implement compat device/sysfs tree in net namespaceParav Pandit
Implement compatibility layer sysfs entries of ib_core so that non init_net net namespaces can also discover rdma devices. Each non init_net net namespace has ib_core_device created in it. Such ib_core_device sysfs tree resembles rdma devices found in init_net namespace. This allows discovering rdma devices in multiple non init_net net namespaces via sysfs entries and helpful to rdma-core userspace.

In order to support sysfs entries in multiple net namespaces for a rdma device, introduce a ib_core_device whose scope is limited to hold core device and per port sysfs related entries. This is preparation patch so that multiple ib_core_devices in each net namespace can be created in subsequent patch who all can share ib_device. (a) Move sysfs specific fields to ib_core_device. (b) Make sysfs and device life cycle related routines to work on ib_core_device. (c) Introduce and use rdma_init_coredev() helper to initialize coredev fields.

2019-03-28KVM: export <linux/kvm_para.h> and <asm/kvm_para.h> iif KVM is supportedMasahiro Yamada
I do not see any consistency about headers_install of <linux/kvm_para.h> and <asm/kvm_para.h>. According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] <asm/kvm_para.h> is exported, but <linux/kvm_para.h> is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported csky, nds32, riscv This does not match to the actual KVM support. At least, [2] is half-baked. Nor do arch maintainers look like they care about this. For example, commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild") exported <asm/kvm_para.h> to user-space in order to fix an in-kernel build error. We have two ways to make this consistent: [A] export both <linux/kvm_para.h> and <asm/kvm_para.h> for all architectures, irrespective of the KVM support [B] Match the header export of <linux/kvm_para.h> and <asm/kvm_para.h> to the KVM support My first attempt was [A] because the code looks cleaner, but Paolo suggested [B]. So, this commit goes with [B]. For most architectures, <asm/kvm_para.h> was moved to the kernel-space. I changed include/uapi/linux/Kbuild so that it checks generated asm/kvm_para.h as well as check-in ones. After this commit, there will be two groups: [1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Cornelia Huck <cohuck@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-03-28kallsyms: store type information in its own arrayEugene Loh
When a module is loaded, its symbols' Elf_Sym information is stored in a symtab. Further, type information is also captured. Since Elf_Sym has no type field, historically the st_info field has been hijacked for storing type: st_info was overwritten. commit 5439c985c5a83a8419f762115afdf560ab72a452 ("module: Overwrite st_size instead of st_info") changes that practice, as its one-liner indicates. Unfortunately, this change overwrites symbol size, information that a tool like DTrace expects to find. Allocate a typetab array to store type information so that no Elf_Sym field needs to be overwritten.

2019-03-28timekeeping: Force upper bound for setting CLOCK_REALTIMEThomas Gleixner
Several people reported testing failures after setting CLOCK_REALTIME close to the limits of the kernel internal representation in nanoseconds, i.e. year 2262. The failures are exposed in subsequent operations, i.e. when arming timers or when the advancing CLOCK_MONOTONIC makes the calculation of CLOCK_REALTIME overflow into negative space. Now people start to paper over the underlying problem by clamping calculations to the valid range, but that's just wrong because such workarounds will prevent detection of real issues as well. It is reasonable to force an upper bound for the various methods of setting CLOCK_REALTIME. Year 2262 is the absolute upper bound. Assume a maximum uptime of 30 years which is plenty enough even for esoteric embedded systems. That results in an upper bound of year 2232 for setting the time. Once that limit is reached in reality this limit is only a small part of the problem space. But until then this stops people from trying to paper over the problem at the wrong places.

My recent patch had at least three problems : 1) TX zerocopy wants notification when skb is acknowledged, thus we need to call skb_zcopy_clear() if the skb is cached into sk->sk_tx_skb_cache 2) Some applications might expect precise EPOLLOUT notifications, so we need to update sk->sk_wmem_queued and call sk_mem_uncharge() from sk_wmem_free_skb() in all cases. The SOCK_QUEUE_SHRUNK flag must also be set. 3) Reuse of saved skb should have used skb_cloned() instead of simply checking if the fast clone has been freed.

2019-03-27net: openvswitch: Add a new action check_pkt_lenNuman Siddique
This patch adds a new action - 'check_pkt_len' which checks the packet length and executes a set of actions if the packet length is greater than the specified length or executes another set of actions if the packet length is lesser or equal to. This action takes below nlattrs * OVS_CHECK_PKT_LEN_ATTR_PKT_LEN - 'pkt_len' to check for * OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_GREATER - Nested actions to apply if the packet length is greater than the specified 'pkt_len' * OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_LESS_EQUAL - Nested actions to apply if the packet length is lesser or equal to the specified 'pkt_len'. The main use case for adding this action is to solve the packet drops because of MTU mismatch in OVN virtual networking solution. When a VM (which belongs to a logical switch of OVN) sends a packet destined to go via the gateway router and if the nic which provides external connectivity, has a lesser MTU, OVS drops the packet if the packet length is greater than this MTU. With the help of this action, OVN will check the packet length and if it is greater than the MTU size, it will generate an ICMP packet (type 3, code 4) and includes the next hop mtu in it so that the sender can fragment the packets.

2019-03-27fou: Support binding FoU socketKristian Evensen
An FoU socket is currently bound to the wildcard-address. While this works fine, there are several use-cases where the use of the wildcard-address is not desirable. For example, I use FoU on some multi-homed servers and would like to use FoU on only one of the interfaces. This commit adds support for binding FoU sockets to a given source address/interface, as well as connecting the socket to a given destination address/port. udp_tunnel already provides the required infrastructure, so most of the code added is for exposing and setting the different attributes (local address, peer address, etc.). The lookups performed when we add, delete or get an FoU-socket has also been updated to compare all the attributes a user can set. Since the comparison now involves several elements, I have added a separate comparison-function instead of open-coding. In order to test the code and ensure that the new comparison code works correctly, I started by creating a wildcard socket bound to port 1234 on my machine. I then tried to create a non-wildcarded socket bound to the same port, as well as fetching and deleting the socket (including source address, peer address or interface index in the netlink request). Both the create, fetch and delete request failed. Deleting/fetching the socket was only successful when my netlink request attributes matched those used to create the socket. I then repeated the tests, but with a socket bound to a local ip address, a socket bound to a local address + interface, and a bound socket that was also «connected» to a peer. Add only worked when no socket with the matching source address/interface (or wildcard) existed, while fetch/delete was only successful when all attributes matched. In addition to testing that the new code work, I also checked that the current behavior is kept. If none of the new attributes are provided, then an FoU-socket is configured as before (i.e., wildcarded). If any of the new attributes are provided, the FoU-socket is configured as expected. v1->v2: * Fixed building with IPv6 disabled (kbuild). * Fixed a return type warning and make the ugly comparison function more readable (kbuild). * Describe more in detail what has been tested (thanks David Miller). * Make peer port required if peer address is specified.

2019-03-27ALSA: Replace snd_malloc_pages() and snd_free_pages() with standard helpers, ↵Takashi Iwai
take#2 snd_malloc_pages() and snd_free_pages() are merely thin wrappers of the standard page allocator / free functions. Even the arguments are compatible with some standard helpers, so there is little merit of keeping these wrappers. This patch replaces the all existing callers of snd_malloc_pages() and snd_free_pages() with the direct calls of the standard helper functions. In this version, we use a recently introduced one, alloc_pages_exact(), which suits better than the old snd_malloc_pages() implementation for our purposes. Then we can avoid the waste of pages by alignment to power-of-two. Since alloc_pages_exact() does split pages, we need no longer __GFP_COMP flag; or better to say, we must not pass __GFP_COMP to alloc_pages_exact(). So the former unconditional addition of __GFP_COMP flag in snd_malloc_pages() is dropped, as well as in most other places.

2019-03-27drm/uapi: Remove unused DRM_DISPLAY_INFO_LENVille Syrjälä
Remove the unused DRM_DISPLAY_INFO_LEN from the uapi headers. I presume the original plan was to expose the display name via getconnector, but looks like that never happened. So we have the define for the length of the string but no string anywhere. A quick scan didn't seem to reveal userspace referencing this so hopefully we can just nuke it.

The fbdev split between fix and var information is kinda pointless for drm drivers since everything is fixed: The fbdev emulation doesn't support changing modes at all.

2019-03-26Input: document meanings of KEY_SCREEN and KEY_ZOOMDmitry Torokhov
It is hard to say what KEY_SCREEN and KEY_ZOOM mean, but historically DVB folks have used them to indicate switch to full screen mode. Later, they converged on using KEY_ZOOM to switch into full screen mode and KEY)SCREEN to control aspect ratio (see Documentation/media/uapi/rc/rc-tables.rst). Let's commit to these uses, and define: - KEY_FULL_SCREEN (and make KEY_ZOOM its alias) - KEY_ASPECT_RATIO (and make KEY_SCREEN its alias) Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
