There is a special case that the size is "(N << KASAN_SHADOW_SCALE_SHIFT) Pages plus X", the value of X is [1, KASAN_SHADOW_SCALE_SIZE-1]. The operation "size >> KASAN_SHADOW_SCALE_SHIFT" will drop X, and the roundup operation can not retrieve the missed one page. For example: size=0x28006, PAGE_SIZE=0x1000, KASAN_SHADOW_SCALE_SHIFT=3, we will get shadow_size=0x5000, but actually we need 6 pages. shadow_size = round_up(size >> KASAN_SHADOW_SCALE_SHIFT, PAGE_SIZE); This can lead to a kernel crash when kasan is enabled and the value of mod->core_layout.size or mod->init_layout.size is like above. Because the shadow memory of X has not been allocated and mapped. move_module: ptr = module_alloc(mod->core_layout.size); ... memset(ptr, 0, mod->core_layout.size); //crashed Unable to handle kernel paging request at virtual address ffff0fffff97b000 ......

When booting with very large numbers of gigantic (i.e. 1G) pages, the operations in the loop of gather_bootmem_prealloc, and specifically prep_compound_gigantic_page, takes a very long time, and can cause a softlockup if enough pages are requested at boot. For example booting with 3844 1G pages requires prepping (set_compound_head, init the count) over 1 billion 4K tail pages, which takes considerable time. Add a cond_resched() to the outer loop in gather_bootmem_prealloc() to prevent this lockup. Tested: Booted with softlockup_panic=1 hugepagesz=1G hugepages=3844 and no softlockup is reported, and the hugepages are reported as successfully setup.

The conflict between my a11e1d43 ("Revert changes to convert to ->poll_mask() and aio IOCB_CMD_POLL") and Ursula Braun's 24ac3a08 ("net/smc: rebuild nonblocking connect") should have left the call to sock_poll_wait() in place, just without the socket lock release/retake. And I really should have realized that. But happily, I at least asked Ursula to double-check the merge, and she set me right. This also fixes an incidental whitespace issue nearby that annoyed me while looking at this. Pointed-out-by:

There are no legacy behavior in drivers to consider while attaching a device to genpd - for the multiple PM domain case. For that reason, let's instead require the driver to runtime resume the device, via calling pm_runtime_get_sync() for example, when it needs to power on the corresponding PM domain. This allows us to improve the situation during attach. Instead of always power on the PM domain, which may be unnecessary, let's leave it in its current state. Additionally, to avoid the PM domain to stay powered on, let's schedule a power off work. Fixes: 3c095f32 (PM / Domains: Add support for multi PM domains ...) Signed-off-by:

Currently, we use the ACPI processor ID only for the leaf/processor nodes as the specification states it must match the value of the ACPI processor ID field in the processor’s entry in the MADT. However, if a PPTT structure represents a processors group, it matches a processor container UID in the namespace and the ACPI_PPTT_ACPI_PROCESSOR_ID_VALID flag indicates whether the ACPI processor ID is valid. Let's use UID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set to be consistent instead of using table offset as it's currently done for non-leaf nodes.

After we change the ipvlan mode from l3 to l2, or vice versa, we only reset IFF_NOARP flag, but don't flush the ARP table cache, which will cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2(). Then the message will not come out of host. Here is the reproducer on local host: ip link set eth1 up ip addr add 192.168.1.1/24 dev eth1 ip link add link eth1 ipvlan1 type ipvlan mode l3 ip netns add net1 ip link set ipvlan1 netns net1 ip netns exec net1 ip link set ipvlan1 up ip netns exec net1 ip addr add 192.168.2.1/24 dev ipvlan1 ip route add 192.168.2.0/24 via 192.168.1.2 ping 192.168.2.2 -c 2 ip netns exec net1 ip link set ipvlan1 type ipvlan mode l2 ping 192.168.2.2 -c 2 Add the same configuration on remote host. After we set the mode to l2, we could find that the src/dst MAC addresses are the same on eth1: 21:26:06.648565 00:b7:13:ad:d3:05 > 00:b7:13:ad:d3:05, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 58356, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.2.1 > 192.168.2.2: ICMP echo request, id 22686, seq 1, length 64 Fix this by calling dev_change_flags(), which will call netdevice notifier with flag change info. v2: a) As pointed out by Wang Cong, check return value for dev_change_flags() when change dev flags. b) As suggested by Stefano and Sabrina, move flags setting before l3mdev_ops. So we don't need to redo ipvlan_{, un}register_nf_hook() again in err path. Reported-by:

Since the addition of GRO for ESP, gro_receive can consume the skb and return -EINPROGRESS. In that case, the lower layer GRO handler cannot touch the skb anymore. Commit 5f114163 ("net: Add a skb_gro_flush_final helper.") converted some of the gro_receive handlers that can lead to ESP's gro_receive so that they wouldn't access the skb when -EINPROGRESS is returned, but missed other spots, mainly in tunneling protocols. This patch finishes the conversion to using skb_gro_flush_final(), and adds a new helper, skb_gro_flush_final_remcsum(), used in VXLAN and GUE.

Booting a ColdFire m68k core with MMU enabled causes a "bad page state" oops since commit 1d40a5ea ("mm: mark pages in use for page tables"): BUG: Bad page state in process sh pfn:01ce2 page:004fefc8 count:0 mapcount:-1024 mapping:00000000 index:0x0 flags: 0x0() raw: 00000000 00000000 00000000 fffffbff 00000000 00000100 00000200 00000000 raw: 039c4000 page dumped because: nonzero mapcount Modules linked in: CPU: 0 PID: 22 Comm: sh Not tainted 4.17.0-07461-g1d40a5ea01d5 #13 Fix by calling pgtable_page_dtor() in our __pte_free_tlb() code path, so that the PG_table flag is cleared before we free the pte page. Note that I had to change the type of pte_free() to be static from extern. Otherwise you get a lot of warnings like this: ./arch/m68k/include/asm/mcf_pgalloc.h:80:2: warning: ‘pgtable_page_dtor’ is static but used in inline function ‘pte_free’ which is not static pgtable_page_dtor(page); ^ And making it static is consistent with our use of this in the other m68k pgalloc definitions of pte_free().

Pull vfs fix from Al Viro: "Followup to procfs-seq_file series this window" This fixes a memory leak by making sure that proc seq files release any private data on close. The 'proc_seq_open' has to be properly paired with 'proc_seq_release' that releases the extra private data. * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: proc: add proc_seq_release
