[ Upstream commit ecd60532 ] 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-g1d40a5ea #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().

[ Upstream commit 484c016d ] Driver performs the internal reload when it receives tx-timeout event from the OS. Internal reload might fail in some scenarios e.g., fatal HW issues. In such cases OS still see the link, which would result in undesirable functionalities such as re-generation of tx-timeouts. The patch addresses this issue by indicating the link-down to OS when tx-timeout is detected, and keeping the link in down state till the internal reload is successful. Please consider applying it to 'net' branch. Signed-off-by:

[ Upstream commit f605ce5e ] If we would ever fail in the bpf_jit_prog() pass that writes the actual insns to the image after we got header via bpf_jit_binary_alloc() then we also need to make sure to free it through bpf_jit_binary_free() again when bailing out. Given we had prior bpf_jit_prog() passes to initially probe for clobbered registers, program size and to fill in addrs arrray for jump targets, this is more of a theoretical one, but at least make sure this doesn't break with future changes.

[ Upstream commit 188f60ab ] Commit 9757235f, "nl80211: correct checks for NL80211_MESHCONF_HT_OPMODE value") relaxed the range for the HT operation field in meshconf, while also adding checks requiring the non-greenfield and non-ht-sta bits to be set in certain circumstances. The latter bit is actually reserved for mesh BSSes according to Table 9-168 in 802.11-2016, so in fact it should not be set. wpa_supplicant sets these bits because the mesh and AP code share the same implementation, but authsae does not. As a result, some meshconf updates from authsae which set only the NONHT_MIXED protection bits were being rejected. In order to avoid breaking userspace by changing the rules again, simply accept the values with or without the bits set, and mask off the reserved bit to match the spec. While in here, update the 802.11-2012 reference to 802.11-2016.

[ Upstream commit bda31539 ] During assemble, the spare marked for replacement is not checked. conf->fullsync cannot be updated to be 1. As a result, recovery will treat it as a clean array. All recovering sectors are skipped. Original device is replaced with the not-recovered spare. mdadm -C /dev/md0 -l10 -n4 -pn2 /dev/loop[0123] mdadm /dev/md0 -a /dev/loop4 mdadm /dev/md0 --replace /dev/loop0 mdadm -S /dev/md0 # stop array during recovery mdadm -A /dev/md0 /dev/loop[01234] After reassemble, you can see recovery go on, but it completes immediately. In fact, recovery is not actually processed. To solve this problem, we just add the missing logics for replacment spares. (In raid1.c or raid5.c, they have already been checked.) Reported-by:

[ Upstream commit 7b4e8843 ] Smack: Mark inode instant in smack_task_to_inode /proc clean-up in commit 1bbc5513 resulted in smack_task_to_inode() being called before smack_d_instantiate. This resulted in the smk_inode value being ignored, even while present for files in /proc/self. Marking the inode as instant here fixes that. Signed-off-by:

[ Upstream commit 6c6da928 ] After recieving MLD querys, we update idev->mc_maxdelay with max_delay from query header. This make the later unsolicited reports have the same interval with mc_maxdelay, which means we may send unsolicited reports with long interval time instead of default configured interval time. Also as we will not call ipv6_mc_reset() after device up. This issue will be there even after leave the group and join other groups.

[ Upstream commit fcc784be ] While debugging where things were going wrong with mapping enabling/disabling interrupts with the lockdep state and actual real enabling and disabling interrupts, I had to silent the IRQ disabling/enabling in debug_check_no_locks_freed() because it was always showing up as it was called before the splat was. Use raw_local_irq_save/restore() for not only debug_check_no_locks_freed() but for all internal lockdep functions, as they hide useful information about where interrupts were used incorrectly last.

[ Upstream commit ba56bc3a ] When booting a 64 KB pages kernel on a ACPI GICv3 system that implements support for v2 emulation, the following warning is produced GICV size 0x2000 not a multiple of page size 0x10000 and support for v2 emulation is disabled, preventing GICv2 VMs from being able to run on such hosts. The reason is that vgic_v3_probe() performs a sanity check on the size of the window (it should be a multiple of the page size), while the ACPI MADT parsing code hardcodes the size of the window to 8 KB. This makes sense, considering that ACPI does not bother to describe the size in the first place, under the assumption that platforms implementing ACPI will follow the architecture and not put anything else in the same 64 KB window. So let's just drop the sanity check altogether, and assume that the window is at least 64 KB in size.

[ Upstream commit 2f24ef74 ] machine_desc->init_per_cpu() hook is supposed to be per cpu initialization and would seem to apply equally to UP and/or SMP. Infact the comment in header file seems to suggest it works for UP too, which was not the case and this patch. This enables !CONFIG_SMP build for platforms such as hsdk. Signed-off-by:

[ Upstream commit d68a90e1 ] Controllers that are not yet enabled should not really enforce keep alive timeouts, but we still want to track a timeout and cleanup in case a host died before it enabled the controller. Hence, simply reset the keep alive timer when the controller is enabled. Suggested-by:

[ Upstream commit bc8a2d9b ] The Stratix10 platform has an additional reset line, OCP(Open Core Protocol), that also needs to get deasserted for the stmmac ethernet controller to work. Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build dwmac-socfpga. Also, remove the redundant check for the reset controller pointer. The reset driver already checks for the pointer and returns 0 if the pointer is NULL. Signed-off-by:
