2019-11-20net/mlx5: DR, Limit STE hash table enlarge based on bytemaskAlex Vesker
When an ste hash table has too many collision we enlarge it to a bigger hash table (rehash). Rehashing collision improvement depends on the bytemask value. The more 1 bits we have in bytemask means better spreading in the table. Without this fix tables can grow in size without providing any improvement which can lead to memory depletion and failures. This patch will limit table rehash to reduce memory and improve the performance.

2019-11-20net/mlx5: DR, Skip rehash for tables with byte mask zeroAlex Vesker
The byte mask fields affect on the hash index distribution, when the byte mask is zero, the hash calculation will always be equal to the same index. To avoid unneeded rehash of hash tables mark the table to skip rehash. This is needed by the next patch which will limit table rehash to reduce memory consumption.

2019-11-20net/mlx5e: Reorder mirrer action parsing to check for encap firstVlad Buslov
Mirred action parsing code in parse_tc_fdb_actions() first checks if out_dev has same parent id, and only verifies that there is a pending encap action that was parsed before. Recent change in vxlan module made function netdev_port_same_parent_id() to return true when called for mlx5 eswitch representor and vxlan device created explicitly on mlx5 representor device (vxlan devices created with "external" flag without explicitly specifying parent interface are not affected). With call to netdev_port_same_parent_id() returning true, incorrect code path is chosen and encap rules fail to offload because vxlan dev is not a valid eswitch forwarding dev. Dmesg log of error: [ 1784.389797] devices ens1f0_0 vxlan1 not on same switch HW, can't offload forwarding In order to fix the issue, rearrange conditional in parse_tc_fdb_actions() to check for pending encap action before checking if out_dev has the same parent id.

2019-11-19net: fec: fix clock count mis-matchChuhong Yuan
pm_runtime_put_autosuspend in probe will call runtime suspend to disable clks automatically if CONFIG_PM is defined. (If CONFIG_PM is not defined, its implementation will be empty, then runtime suspend will not be called.) Therefore, we can call pm_runtime_get_sync to runtime resume it first to enable clks, which matches the runtime suspend. (Only when CONFIG_PM is defined, otherwise pm_runtime_get_sync will also be empty, then runtime resume will not be called.) Then it is fine to disable clks without causing clock count mis-match.

2019-11-19net: phylink: fix link mode modification in PHY modeRussell King
Modifying the link settings via phylink_ethtool_ksettings_set() and phylink_ethtool_set_pauseparam() didn't always work as intended for PHY based setups, as calling phylink_mac_config() would result in the unresolved configuration being committed to the MAC, rather than the configuration with the speed and duplex setting. This would work fine if the update caused the link to renegotiate, but if no settings have changed, phylib won't trigger a renegotiation cycle, and the MAC will be left incorrectly configured. Avoid calling phylink_mac_config() unless we are using an inband mode in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as introduced in 4.20 to set the PHY settings in phylink_ethtool_set_pauseparam().

2019-11-19r8169: disable TSO on a single version of RTL8168c to fix performanceCorinna Vinschen
During performance testing, I found that one of my r8169 NICs suffered a major performance loss, a 8168c model. Running netperf's TCP_STREAM test didn't return the expected throughput of > 900 Mb/s, but rather only about 22 Mb/s. Strange enough, running the TCP_MAERTS and UDP_STREAM tests all returned with throughput > 900 Mb/s, as did TCP_STREAM with the other r8169 NICs I can test (either one of 8169s, 8168e, 8168f). Bisecting turned up commit 93681cd7d94f83903cb3f0f95433d10c28a7e9a5, "r8169: enable HW csum and TSO" as the culprit. I added my 8168c version, RTL_GIGA_MAC_VER_22, to the code special-casing the 8168evl as per the patch below. This fixed the performance problem for me.

The taprio qdisc allows to set mqprio setting but only once. In case if mqprio settings are provided next time the error is returned as it's not allowed to change traffic class mapping in-flignt and that is normal. But if configuration is absolutely the same - no need to return error. It allows to provide same command couple times, changing only base time for instance, or changing only scheds maps, but leaving mqprio setting w/o modification. It more corresponds the message: "Changing the traffic mapping of a running schedule is not supported", so reject mqprio if it's really changed.

2019-11-18mlxsw: spectrum_router: Fix determining underlay for a GRE tunnelPetr Machata
The helper mlxsw_sp_ipip_dev_ul_tb_id() determines the underlay VRF of a GRE tunnel. For a tunnel without a bound device, it uses the same VRF that the tunnel is in. However in Linux, a GRE tunnel without a bound device uses the main VRF as the underlay. Fix the function accordingly. mlxsw further assumed that moving a tunnel to a different VRF could cause conflict in local tunnel endpoint address, which cannot be offloaded. However, the only way that an underlay could be changed by moving the tunnel device itself is if the tunnel device does not have a bound device. But in that case the underlay is always the main VRF, so there is no opportunity to introduce a conflict by moving such device. Thus this check constitutes a dead code, and can be removed, which do.

2019-11-16ipmr: Fix skb headroom in ipmr_get_route().Guillaume Nault
In route.c, inet_rtm_getroute_build_skb() creates an skb with no headroom. This skb is then used by inet_rtm_getroute() which may pass it to rt_fill_info() and, from there, to ipmr_get_route(). The later might try to reuse this skb by cloning it and prepending an IPv4 header. But since the original skb has no headroom, skb_push() triggers skb_under_panic(): skbuff: skb_under_panic: text:00000000ca46ad8a len:80 put:20 head:00000000cd28494e data:000000009366fd6b tail:0x3c end:0xec0 dev:veth0 ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:108! invalid opcode: 0000 [#1] SMP KASAN PTI CPU: 6 PID: 587 Comm: ip Not tainted 5.4.0-rc6+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-2.fc30 04/01/2014 RIP: 0010:skb_panic+0xbf/0xd0 Code: 41 a2 ff 8b 4b 70 4c 8b 4d d0 48 c7 c7 20 76 f5 8b 44 8b 45 bc 48 8b 55 c0 48 8b 75 c8 41 54 41 57 41 56 41 55 e8 75 dc 7a ff <0f> 0b 0f 1f 44 00 00 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 RSP: 0018:ffff888059ddf0b0 EFLAGS: 00010286 RAX: 0000000000000086 RBX: ffff888060a315c0 RCX: ffffffff8abe4822 RDX: 0000000000000000 RSI: 0000000000000008 RDI: ffff88806c9a79cc RBP: ffff888059ddf118 R08: ffffed100d9361b1 R09: ffffed100d9361b0 R10: ffff88805c68aee3 R11: ffffed100d9361b1 R12: ffff88805d218000 R13: ffff88805c689fec R14: 000000000000003c R15: 0000000000000ec0 FS: 00007f6af184b700(0000) GS:ffff88806c980000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007ffc8204a000 CR3: 0000000057b40006 CR4: 0000000000360ee0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: skb_push+0x7e/0x80 ipmr_get_route+0x459/0x6fa rt_fill_info+0x692/0x9f0 inet_rtm_getroute+0xd26/0xf20 rtnetlink_rcv_msg+0x45d/0x630 netlink_rcv_skb+0x1a5/0x220 rtnetlink_rcv+0x15/0x20 netlink_unicast+0x305/0x3a0 netlink_sendmsg+0x575/0x730 sock_sendmsg+0xb5/0xc0 ___sys_sendmsg+0x497/0x4f0 __sys_sendmsg+0xcb/0x150 __x64_sys_sendmsg+0x48/0x50 do_syscall_64+0xd2/0xac0 entry_SYSCALL_64_after_hwframe+0x49/0xbe Actually the original skb used to have enough headroom, but the reserve_skb() call was lost with the introduction of inet_rtm_getroute_build_skb() by commit 404eb77ea766 ("ipv4: support sport, dport and ip_proto in RTM_GETROUTE").

2019-11-16net/smc: fix fastopen for non-blocking connect()Ursula Braun
FASTOPEN does not work with SMC-sockets. Since SMC allows fallback to TCP native during connection start, the FASTOPEN setsockopts trigger this fallback, if the SMC-socket is still in state SMC_INIT. But if a FASTOPEN setsockopt is called after a non-blocking connect(), this is broken, and fallback does not make sense. This change complements commit cd2063604ea6 ("net/smc: avoid fallback in case of non-blocking connect") and fixes the syzbot reported problem "WARNING in smc_unhash_sk".

2019-11-16seg6: fix skb transport_header after decap_and_validate()Andrea Mayer
in the receive path (more precisely in ip6_rcv_core()) the skb->transport_header is set to skb->network_header + sizeof(*hdr). As a consequence, after routing operations, destination input expects to find skb->transport_header correctly set to the next protocol (or extension header) that follows the network protocol. However, decap behaviors (DX*, DT*) remove the outer IPv6 and SRH extension and do not set again the skb->transport_header pointer correctly. For this reason, the patch sets the skb->transport_header to the skb->network_header + sizeof(hdr) in each DX* and DT* behavior.

2019-11-15mm/debug.c: PageAnon() is true for PageKsm() pagesRalph Campbell
PageAnon() and PageKsm() use the low two bits of the page->mapping pointer to indicate the page type. PageAnon() only checks the LSB while PageKsm() checks the least significant 2 bits are equal to 3. Therefore, PageAnon() is true for KSM pages. __dump_page() incorrectly will never print "ksm" because it checks PageAnon() first. Fix this by checking PageKsm() first.

2019-11-15mm/page_io.c: do not free shared swap slotsVinayak Menon
The following race is observed due to which a processes faulting on a swap entry, finds the page neither in swapcache nor swap. This causes zram to give a zero filled page that gets mapped to the process, resulting in a user space crash later. Consider parent and child processes Pa and Pb sharing the same swap slot with swap_count 2. Swap is on zram with SWP_SYNCHRONOUS_IO set. Virtual address 'VA' of Pa and Pb points to the shared swap entry. Pa Pb fault on VA fault on VA do_swap_page do_swap_page lookup_swap_cache fails lookup_swap_cache fails Pb scheduled out swapin_readahead (deletes zram entry) swap_free (makes swap_count 1) Pb scheduled in swap_readpage (swap_count == 1) Takes SWP_SYNCHRONOUS_IO path zram enrty absent zram gives a zero filled page Fix this by making sure that swap slot is freed only when swap count drops down to one.

2019-11-15mm/memory_hotplug: fix try_offline_node()David Hildenbrand
try_offline_node() is pretty much broken right now: - The node span is updated when onlining memory, not when adding it. We ignore memory that was mever onlined. Bad. - We touch possible garbage memmaps. The pfn_to_nid(pfn) can easily trigger a kernel panic. Bad for memory that is offline but also bad for subsection hotadd with ZONE_DEVICE, whereby the memmap of the first PFN of a section might contain garbage. - Sections belonging to mixed nodes are not properly considered. As memory blocks might belong to multiple nodes, we would have to walk all pageblocks (or at least subsections) within present sections. However, we don't have a way to identify whether a memmap that is not online was initialized (relevant for ZONE_DEVICE). This makes things more complicated. Luckily, we can piggy pack on the node span and the nid stored in memory blocks. Currently, the node span is grown when calling move_pfn_range_to_zone() - e.g., when onlining memory, and shrunk when removing memory, before calling try_offline_node(). Sysfs links are created via link_mem_sections(), e.g., during boot or when adding memory. If the node still spans memory or if any memory block belongs to the nid, we don't set the node offline. As memory blocks that span multiple nodes cannot get offlined, the nid stored in memory blocks is reliable enough (for such online memory blocks, the node still spans the memory). Introduce for_each_memory_block() to efficiently walk all memory blocks. Note: We will soon stop shrinking the ZONE_DEVICE zone and the node span when removing ZONE_DEVICE memory to fix similar issues (access of garbage memmaps) - until we have a reliable way to identify whether these memmaps were properly initialized. This implies later, that once a node had ZONE_DEVICE memory, we won't be able to set a node offline - which should be acceptable. Since commit f1dd2cd13c4b ("mm, memory_hotplug: do not associate hotadded memory to zones until online") memory that is added is not assoziated with a zone/node (memmap not initialized). The introducing commit 60a5a19e7419 ("memory-hotplug: remove sysfs file of node") already missed that we could have multiple nodes for a section and that the zone/node span is updated when onlining pages, not when adding them. I tested this by hotplugging two DIMMs to a memory-less and cpu-less NUMA node. The node is properly onlined when adding the DIMMs. When removing the DIMMs, the node is properly offlined.
