In commit dc9c4d0f, the arp_target array moved from a static global to a local variable. By the nature of static globals, the array used to be initialized to all 0. At present, it's full of random data, which that gets interpreted as arp_target values, when none have actually been specified. Systems end up booting with spew along these lines: [ 32.161783] IPv6: ADDRCONF(NETDEV_UP): lacp0: link is not ready [ 32.168475] IPv6: ADDRCONF(NETDEV_UP): lacp0: link is not ready [ 32.175089] 8021q: adding VLAN 0 to HW filter on device lacp0 [ 32.193091] IPv6: ADDRCONF(NETDEV_UP): lacp0: link is not ready [ 32.204892] lacp0: Setting MII monitoring interval to 100 [ 32.211071] lacp0: Removing ARP target 216.124.228.17 [ 32.216824] lacp0: Removing ARP target 218.160.255.255 [ 32.222646] lacp0: Removing ARP target 185.170.136.184 [ 32.228496] lacp0: invalid ARP target 255.255.255.255 specified for removal [ 32.236294] lacp0: option arp_ip_target: invalid value (-255.255.255.255) [ 32.243987] lacp0: Removing ARP target 56.125.228.17 [ 32.249625] lacp0: Removing ARP target 218.160.255.255 [ 32.255432] lacp0: Removing ARP target 15.157.233.184 [ 32.261165] lacp0: invalid ARP target 255.255.255.255 specified for removal [ 32.268939] lacp0: option arp_ip_target: invalid value (-255.255.255.255) [ 32.276632] lacp0: Removing ARP target 16.0.0.0 [ 32.281755] lacp0: Removing ARP target 218.160.255.255 [ 32.287567] lacp0: Removing ARP target 72.125.228.17 [ 32.293165] lacp0: Removing ARP target 218.160.255.255 [ 32.298970] lacp0: Removing ARP target 8.125.228.17 [ 32.304458] lacp0: Removing ARP target 218.160.255.255 None of these were actually specified as ARP targets, and the driver does seem to clean up the mess okay, but it's rather noisy and confusing, leaks values to userspace, and the 255.255.255.255 spew shows up even when debug prints are disabled.

As of 7bb11dc9 and 0622cab0, bond slaves in a 3ad bond are not removed from the aggregator when they are down, and the active slave count is NOT equal to number of ports in the aggregator, but rather the number of ports in the aggregator that are still enabled. The sysfs spew for bonding_show_ad_num_ports() has a comment that says "Show number of active 802.3ad ports.", but it's currently showing total number of ports, both active and inactive. Remedy it by using the same logic introduced in 0622cab0 in __bond_3ad_get_active_agg_info(), so sysfs, procfs and netlink all report the number of active ports. Note that this means that IFLA_BOND_AD_INFO_NUM_PORTS really means NUM_ACTIVE_PORTS instead of NUM_PORTS, and thus perhaps should be renamed for clarity. Lightly tested on a dual i40e lacp bond, simulating link downs with an ip link set dev <slave2> down, was able to produce the state where I could see both in the same aggregator, but a number of ports count of 1.

The code to fetch a 64-bit value from user space was entirely buggered, and has been since the code was merged in early 2016 in commit b2f68038 ("x86/mm/32: Add support for 64-bit __get_user() on 32-bit kernels"). Happily the buggered routine is almost certainly entirely unused, since the normal way to access user space memory is just with the non-inlined "get_user()", and the inlined version didn't even historically exist. The normal "get_user()" case is handled by external hand-written asm in arch/x86/lib/getuser.S that doesn't have either of these issues. There were two independent bugs in __get_user_asm_u64(): - it still did the STAC/CLAC user space access marking, even though that is now done by the wrapper macros, see commit 11f1a4b9 ("x86: reorganize SMAP handling in user space accesses"). This didn't result in a semantic error, it just means that the inlined optimized version was hugely less efficient than the allegedly slower standard version, since the CLAC/STAC overhead is quite high on modern Intel CPU's. - the double register %eax/%edx was marked as an output, but the %eax part of it was touched early in the asm, and could thus clobber other inputs to the asm that gcc didn't expect it to touch. In particular, that meant that the generated code could look like this: mov (%eax),%eax mov 0x4(%eax),%edx where the load of %edx obviously was _supposed_ to be from the 32-bit word that followed the source of %eax, but because %eax was overwritten by the first instruction, the source of %edx was basically random garbage. The fixes are trivial: remove the extraneous STAC/CLAC entries, and mark the 64-bit output as early-clobber to let gcc know that no inputs should alias with the output register.

Al noticed that unsafe_put_user() had type problems, and fixed them in commit a7cc722f ("fix unsafe_put_user()"), which made me look more at those functions. It turns out that unsafe_get_user() had a type issue too: it limited the largest size of the type it could handle to "unsigned long". Which is fine with the current users, but doesn't match our existing normal get_user() semantics, which can also handle "u64" even when that does not fit in a long. While at it, also clean up the type cast in unsafe_put_user(). We actually want to just make it an assignment to the expected type of the pointer, because we actually do want warnings from types that don't convert silently. And it makes the code more readable by not having that one very long and complex line. [ This patch might become stable material if we ever end up back-porting any new users of the unsafe uaccess code, but as things stand now this doesn't matter for any current existing uses. ] Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Since commit 76b91c32 ("bridge: stp: when using userspace stp stop kernel hello and hold timers"), bridge would not start hello_timer if stp_enabled is not KERNEL_STP when br_dev_open. The problem is even if users set stp_enabled with KERNEL_STP later, the timer will still not be started. It causes that KERNEL_STP can not really work. Users have to re-ifup the bridge to avoid this. This patch is to fix it by starting br->hello_timer when enabling KERNEL_STP in br_stp_start. As an improvement, it's also to start hello_timer again only when br->stp_enabled is KERNEL_STP in br_hello_timer_expired, there is no reason to start the timer again when it's NO_STP.

Ihar Hrachyshka says: ==================== arp: always override existing neigh entries with gratuitous ARP This patchset is spurred by discussion started at https://patchwork.ozlabs.org/patch/760372/ where we figured that there is no real reason for enforcing override by gratuitous ARP packets only when arp_accept is 1. Same should happen when it's 0 (the default value). changelog v2: handled review comments by Julian Anastasov - fixed a mistake in a comment; - postponed addr_type calculation to as late as possible. ==================== Signed-off-by: David S.

Ihar Hrachyshka authored
Currently, when arp_accept is 1, we always override existing neigh entries with incoming gratuitous ARP replies. Otherwise, we override them only if new replies satisfy _locktime_ conditional (packets arrive not earlier than _locktime_ seconds since the last update to the neigh entry). The idea behind locktime is to pick the very first (=> close) reply received in a unicast burst when ARP proxies are used. This helps to avoid ARP thrashing where Linux would switch back and forth from one proxy to another. This logic has nothing to do with gratuitous ARP replies that are generally not aligned in time when multiple IP address carriers send them into network. This patch enforces overriding of existing neigh entries by all incoming gratuitous ARP packets, irrespective of their time of arrival. This will make the kernel honour all incoming gratuitous ARP packets. Signed-off-by: Ihar Hrachyshka <ihrachys@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The addr_type retrieval can be costly, so it's worth trying to avoid its calculation as much as possible. This patch makes it calculated only for gratuitous ARP packets. This is especially important since later we may want to move is_garp calculation outside of arp_accept block, at which point the costly operation will be executed for all setups.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS fixes for net The following patchset contains Netfilter/IPVS fixes for your net tree, they are: 1) When using IPVS in direct-routing mode, normal traffic from the LVS host to a back-end server is sometimes incorrectly NATed on the way back into the LVS host. Patch to fix this from Julian Anastasov. 2) Calm down clang compilation warning in ctnetlink due to type mismatch, from Matthias Kaehlcke. 3) Do not re-setup NAT for conntracks that are already confirmed, this is fixing a problem that was introduced in the previous nf-next batch. Patch from Liping Zhang. 4) Do not allow conntrack helper removal from userspace cthelper infrastructure if already in used. This comes with an initial patch to introduce nf_conntrack_helper_put() that is required by this fix. From Liping Zhang. 5) Zero the pad when copying data to userspace, otherwise iptables fails to remove rules. This is a follow up on the patchset that sorts out the internal match/target structure pointer leak to userspace. Patch from the same author, Willem de Bruijn. This also comes with a build failure when CONFIG_COMPAT is not on, coming in the last patch of this series. 6) SYNPROXY crashes with conntrack entries that are created via ctnetlink, more specifically via conntrackd state sync. Patch from Eric Leblond. 7) RCU safe iteration on set element dumping in nf_tables, from Liping Zhang. 8) Missing sanitization of immediate date for the bitwise and cmp expressions in nf_tables. 9) Refcounting logic for chain and objects from set elements does not integrate into the nf_tables 2-phase commit protocol. 10) Missing sanitization of target verdict in ebtables arpreply target, from Gao Feng. ==================== Signed-off-by: David S.

Pull USB fixes from Greg KH: "Here are a number of small USB fixes for 4.12-rc2 Most of them come from Johan, in his valiant quest to fix up all drivers that could be affected by "malicious" USB devices. There's also some fixes for more "obscure" drivers to handle some of the vmalloc stack fallout (which for USB drivers, was always the case, but very few people actually ran those systems...)

Pull libnvdimm fixes from Dan Williams: "A couple of compile fixes. With the removal of the ->direct_access() method from block_device_operations in favor of a new dax_device + dax_operations we broke two configurations. The CONFIG_BLOCK=n case is fixed by compiling out the block+dax helpers in the dax core. Configurations with FS_DAX=n EXT4=y / XFS=y and DAX=m fail due to the helpers the builtin filesystem needs being in a module, so we stub out the helpers in the FS_DAX=n case." * 'libnvdimm-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: dax, xfs, ext4: compile out iomap-dax paths in the FS_DAX=n case dax: fix false CONFIG_BLOCK dependency
