Created an abstract power management layer to operate MHI in bus master, and slave mode. PCIe bus, device, slot are extracted from DT to identify physical device.

If interrupt is disabled more than one tick(10ms), timer interrupts are missed and jiffies can't be updated at every 10ms and it can be behind the real time. So add API to force re- selection of the best clocksource among registered clocksources so that the best clocksource can be selected whenever it is available.

These errors would be detected by ICE HCI and triggers interrupt. The two errors are: 1. Generic Crypto Error (GCE): This error is detected during the transfer. Need to reset SDHC to recover. 2. Invalid Crypto Configuration Error (ICCE): The HW detects it before the beginning of the transfer and terminates the transfer before actual execution started. Driver has to handle these error for recovering ICE-HCI from these error conditions. This patch is for handling there errors in cmdq mode.

This is to ensure that mmc rescan work item is doesn't get blocked on claim_host for longer period. In the pm_suspend path, we cancel the mmc_rescan work item. If this work item is already scheduled, suspend would be blocked till mmc_rescan gets finished. In case, mmc_rescan is blocked on claim_host lock, pm_suspend could get blocked for longer period. This can result in momentary UI freeze since pm_suspend is blocked for longer duration. This change is to prevent this scenario.

Somehow I ended up with an off-by-three error in calculating the size of the PASID and PASID State tables, which triggers allocations failures as those tables unfortunately have to be physically contiguous. In fact, even the *correct* maximum size of 8MiB is problematic and is wont to lead to allocation failures. Since I have extracted a promise that this *will* be fixed in hardware, I'm happy to limit it on the current hardware to a maximum of 0x20000 PASIDs, which gives us 1MiB tables — still not ideal, but better than before. Reported by Mika Kuoppala <mika.kuoppala@linux.intel.com> and also by Xunlei Pang <xlpang@redhat.com> who submitted a simpler patch to fix only the allocation (and not the free) to the "correct" limit... which was still problematic.

To keep it NMI safe since we're accessing from tracing, we're not using a separate timekeeper with updates to monotonic clock and boot offset protected with seqlocks. This has the following minor side effects: (1) Its possible that a timestamp be taken after the boot offset is updated but before the timekeeper is updated. If this happens, the new boot offset is added to the old timekeeping making the clock appear to update slightly earlier: CPU 0 CPU 1 timekeeping_inject_sleeptime64() __timekeeping_inject_sleeptime(tk, delta); timestamp(); timekeeping_update(tk, TK_CLEAR_NTP...); (2) On 32-bit systems, the 64-bit boot offset (tk->offs_boot) may be partially updated. Since the tk->offs_boot update is a rare event, this should be a rare occurrence which postprocessing should be able to handle.

It probably was expecting a simple DROP or ACCEPT behavior. We first need to make sure no part of TCP header could be removed. Then we need to adjust TCP_SKB_CB(skb)->end_seq Many thanks to syzkaller team and Marco for giving us a reproducer.

This was fixed for tunneling protocols by limiting tunnel GRO to one level with encap_mark, but both VLAN and TEB still have this problem. Thus, the kernel is vulnerable to a stack overflow, if we receive a packet composed entirely of VLAN headers. This patch adds a recursion counter to the GRO layer to prevent stack overflow. When a gro_receive function hits the recursion limit, GRO is aborted for this skb and it is processed normally. This recursion counter is put in the GRO CB, but could be turned into a percpu counter if we run out of space in the CB. Thanks to Vladimír Beneš <vbenes@redhat.com> for the initial bug report.

Since the skb is new the portid is 0 at that point so the packets are sent to the kernel and we get scheduling while atomic or a deadlock (depending on where it happens) by trying to acquire rtnl two times.

To achieve that goal, this patch moves ARM64 PSCI idle management code to drivers/firmware, so that the interface to initialize and enter idle states can actually be shared by ARM and ARM64 arches back-ends. The ARM generic CPUidle implementation also requires the definition of a cpuidle_ops section entry for the kernel to initialize the CPUidle operations at boot based on the enable-method (ie ARM64 has the statically initialized cpu_ops counterparts for that purpose); therefore this patch also adds the required section entry on CONFIG_ARM for PSCI so that the kernel can initialize the PSCI CPUidle back-end when PSCI is the probed enable-method. On ARM64 this patch provides no functional change.

When drivers express support for TSO of encapsulated packets, they only mean that they can do it for one layer of encapsulation. Supporting additional levels would mean updating, at a minimum, more IP length fields and they are unaware of this. No encapsulation device expresses support for handling offloaded encapsulated packets, so we won't generate these types of frames in the transmit path. However, GRO doesn't have a check for multiple levels of encapsulation and will attempt to build them. UDP tunnel GRO actually does prevent this situation but it only handles multiple UDP tunnels stacked on top of each other. This generalizes that solution to prevent any kind of tunnel stacking that would cause problems.

When file permissions are modified via chmod(2) and the user is not in the owning group or capable of CAP_FSETID, the setgid bit is cleared in inode_change_ok(). Setting a POSIX ACL via setxattr(2) sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way; this allows to bypass the check in chmod(2). Fix that.

That just generally kills the machine, and makes debugging only much harder, since the traces may long be gone. Debugging by assert() is a disease. Don't do it. If you can continue, you're much better off doing so with a live machine where you have a much higher chance that the report actually makes it to the system logs, rather than result in a machine that is just completely dead. The only valid situation for BUG_ON() is when continuing is not an option, because there is massive corruption. But if you are just verifying that something is true, you warn about your broken assumptions (preferably just once), and limp on.

Antonio reports the following crash when using fuse under memory pressure: kernel BUG at /build/linux-a2WvEb/linux-4.4.0/mm/workingset.c:346! invalid opcode: 0000 [#1] SMP Modules linked in: all of them CPU: 2 PID: 63 Comm: kswapd0 Not tainted 4.4.0-36-generic #55-Ubuntu Hardware name: System manufacturer System Product Name/P8H67-M PRO, BIOS 3904 04/27/2013 task: ffff88040cae6040 ti: ffff880407488000 task.ti: ffff880407488000 RIP: shadow_lru_isolate+0x181/0x190 Call Trace: __list_lru_walk_one.isra.3+0x8f/0x130 list_lru_walk_one+0x23/0x30 scan_shadow_nodes+0x34/0x50 shrink_slab.part.40+0x1ed/0x3d0 shrink_zone+0x2ca/0x2e0 kswapd+0x51e/0x990 kthread+0xd8/0xf0 ret_from_fork+0x3f/0x70 which corresponds to the following sanity check in the shadow node tracking: BUG_ON(node->count & RADIX_TREE_COUNT_MASK); The workingset code tracks radix tree nodes that exclusively contain shadow entries of evicted pages in them, and this (somewhat obscure) line checks whether there are real pages left that would interfere with reclaim of the radix tree node under memory pressure. While discussing ways how fuse might sneak pages into the radix tree past the workingset code, Miklos pointed to replace_page_cache_page(), and indeed there is a problem there: it properly accounts for the old page being removed - __delete_from_page_cache() does that - but then does a raw raw radix_tree_insert(), not accounting for the replacement page. Eventually the page count bits in node->count underflow while leaving the node incorrectly linked to the shadow node LRU. To address this, make sure replace_page_cache_page() uses the tracked page insertion code, page_cache_tree_insert(). This fixes the page accounting and makes sure page-containing nodes are properly unlinked from the shadow node LRU again. Also, make the sanity checks a bit less obscure by using the helpers for checking the number of pages and shadows in a radix tree node.
