[ Upstream commit 522040ea ] ECN signals currently forces TCP to enter quickack mode for up to 16 (TCP_MAX_QUICKACKS) following incoming packets. We believe this is not needed, and only sending one immediate ack for the current packet should be enough. This should reduce the extra load noticed in DCTCP environments, after congestion events. This is part 2 of our effort to reduce pure ACK packets. Signed-off-by:

[ Upstream commit a3893637 ] As explained in commit 9f9843a7 ("tcp: properly handle stretch acks in slow start"), TCP stacks have to consider how many packets are acknowledged in one single ACK, because of GRO, but also because of ACK compression or losses. We plan to add SACK compression in the following patch, we must therefore not call tcp_enter_quickack_mode() Signed-off-by:

[ Upstream commit 383d4709 ] For some very small BDPs (with just a few packets) there was a quantization effect where the target number of packets in flight during the super-unity-gain (1.25x) phase of gain cycling was implicitly truncated to a number of packets no larger than the normal unity-gain (1.0x) phase of gain cycling. This meant that in multi-flow scenarios some flows could get stuck with a lower bandwidth, because they did not push enough packets inflight to discover that there was more bandwidth available. This was really only an issue in multi-flow LAN scenarios, where RTTs and BDPs are low enough for this to be an issue. This fix ensures that gain cycling can raise inflight for small BDPs by ensuring that in PROBE_BW mode target inflight values with a super-unity gain are always greater than inflight values with a gain <= 1. Importantly, this applies whether the inflight value is calculated for use as a cwnd value, or as a target inflight value for the end of the super-unity phase in bbr_is_next_cycle_phase() (both need to be bigger to ensure we can probe with more packets in flight reliably). This is a candidate fix for stable releases. Fixes: 0f8782ea ("tcp_bbr: add BBR congestion control") Signed-off-by:

[ Upstream commit 9939a46d ] As for today STMMAC_ALIGN macro (which is used to align DMA stuff) relies on L1 line length (L1_CACHE_BYTES). This isn't correct in case of system with several cache levels which might have L1 cache line length smaller than L2 line. This can lead to sharing one cache line between DMA buffer and other data, so we can lose this data while invalidate DMA buffer before DMA transaction. Fix that by using SMP_CACHE_BYTES instead of L1_CACHE_BYTES for aligning. Signed-off-by:

commit 940efcc8 upstream. Flows can be created on UD and RAW_PACKET QP types. Attempts to provide other QP types as an input causes to various unpredictable failures. The reason is that in order to support all various types (e.g. XRC), we are supposed to use real_qp handle and not qp handle and expect to driver/FW to fail such (XRC) flows. The simpler and safer variant is to ban all QP types except UD and RAW_PACKET, instead of relying on driver/FW.

commit 493fb50e upstream. Certain Thunderbolt 1 controllers claim to support Command Completed events (value of 0b in the No Command Completed Support field of the Slot Capabilities register) but in reality they neither set the Command Completed bit in the Slot Status register nor signal a Command Completed interrupt: 8086:1513 CV82524 [Light Ridge 4C 2010] 8086:151a DSL2310 [Eagle Ridge 2C 2011] 8086:151b CVL2510 [Light Peak 2C 2010] 8086:1547 DSL3510 [Cactus Ridge 4C 2012] 8086:1548 DSL3310 [Cactus Ridge 2C 2012] 8086:1549 DSL2210 [Port Ridge 1C 2011] All known newer chips (Redwood Ridge and onwards) set No Command Completed Support, indicating that they do not support Command Completed events. The user-visible impact is that after unplugging such a device, 2 seconds elapse until pciehp is unbound. That's because on ->remove, pcie_write_cmd() is called via pcie_disable_notification() and every call to pcie_write_cmd() takes 2 seconds (1 second for each invocation of pcie_wait_cmd()): [ 337.942727] pciehp 0000:0a:00.0:pcie204: Timeout on hotplug command 0x1038 (issued 21176 msec ago) [ 340.014735] pciehp 0000:0a:00.0:pcie204: Timeout on hotplug command 0x0000 (issued 2072 msec ago) That by itself has always been unpleasant, but the situation has become worse with commit cc27b735 ("PCI/portdrv: Turn off PCIe services during shutdown"): Now pciehp is unbound on ->shutdown. Because Thunderbolt controllers typically have 4 hotplug ports, every reboot and shutdown is now delayed by 8 seconds, plus another 2 seconds for every attached Thunderbolt 1 device. Thunderbolt hotplug slots are not physical slots that one inserts cards into, but rather logical hotplug slots implemented in silicon. Devices appear beyond those logical slots once a PCI tunnel is established on top of the Thunderbolt Converged I/O switch. One would expect commands written to the Slot Control register to be executed immediately by the silicon, so for simplicity we always assume NoCompl+ for Thunderbolt ports.

commit 50122847 upstream. Commit 8844618d: "ext4: only look at the bg_flags field if it is valid" will complain if block group zero does not have the EXT4_BG_INODE_ZEROED flag set. Unfortunately, this is not correct, since a freshly created file system has this flag cleared. It gets almost immediately after the file system is mounted read-write --- but the following somewhat unlikely sequence will end up triggering a false positive report of a corrupted file system: mkfs.ext4 /dev/vdc mount -o ro /dev/vdc /vdc mount -o remount,rw /dev/vdc Instead, when initializing the inode table for block group zero, test to make sure that itable_unused count is not too large, since that is the case that will result in some or all of the reserved inodes getting cleared. This fixes the failures reported by Eric Whiteney when running generic/230 and generic/231 in the the nojournal test case.

commit 8d5a803c upstream. With commit 044e6e3d: "ext4: don't update checksum of new initialized bitmaps" the buffer valid bit will get set without actually setting up the checksum for the allocation bitmap, since the checksum will get calculated once we actually allocate an inode or block. If we are doing this, then we need to (re-)check the verified bit after we take the block group lock. Otherwise, we could race with another process reading and verifying the bitmap, which would then complain about the checksum being invalid. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1780137Signed-off-by:

commit 362eca70 upstream. The inline data code was updating the raw inode directly; this is problematic since if metadata checksums are enabled, ext4_mark_inode_dirty() must be called to update the inode's checksum. In addition, the jbd2 layer requires that get_write_access() be called before the metadata buffer is modified.

commit 01cfb793 upstream. Anatoly Trosinenko reports that a corrupted squashfs image can cause a kernel oops. It turns out that squashfs can end up being confused about negative fragment lengths. The regular squashfs_read_data() does check for negative lengths, but squashfs_read_metadata() did not, and the fragment size code just blindly trusted the on-disk value. Fix both the fragment parsing and the metadata reading code. Reported-by:

commit 81e69df3 upstream. Fedora has integrated the jitter entropy daemon to work around slow boot problems, especially on VM's that don't support virtio-rng: https://bugzilla.redhat.com/show_bug.cgi?id=1572944 It's understandable why they did this, but the Jitter entropy daemon works fundamentally on the principle: "the CPU microarchitecture is **so** complicated and we can't figure it out, so it *must* be random". Yes, it uses statistical tests to "prove" it is secure, but AES_ENCRYPT(NSA_KEY, COUNTER++) will also pass statistical tests with flying colors. So if RDRAND is available, mix it into entropy submitted from userspace. It can't hurt, and if you believe the NSA has backdoored RDRAND, then they probably have enough details about the Intel microarchitecture that they can reverse engineer how the Jitter entropy daemon affects the microarchitecture, and attack its output stream. And if RDRAND is in fact an honest DRNG, it will immeasurably improve on what the Jitter entropy daemon might produce. This also provides some protection against someone who is able to read or set the entropy seed file. Signed-off-by:

[ Upstream commit 5e9cfeba ] drm_atomic_helper_shutdown() needs to release the reference held by plane->fb. Since commit 49d70aea ("drm/atomic-helper: Fix leak in disable_all") we're doing that by calling drm_atomic_clean_old_fb() in drm_atomic_helper_disable_all(). This also leaves plane->fb == NULL afterwards. However, since drm_atomic_helper_disable_all() is also used by the i915 gpu reset code drm_atomic_helper_commit_duplicated_state() then has to undo the damage and put the correct plane->fb pointers back in (and also adjust the ref counts to match again as well). That approach doesn't work so well for load detection as nothing sets up the plane->old_fb pointers for us. This causes us to leak an extra reference for each plane->fb when drm_atomic_helper_commit_duplicated_state() calls drm_atomic_clean_old_fb() after load detection. To fix this let's call drm_atomic_clean_old_fb() only for drm_atomic_helper_shutdown() as that's the only time we need to actually drop the plane->fb references. In all the other cases (load detection, gpu reset) we want to leave plane->fb alone. v2: Don't inflict the clean_old_fbs bool to drivers (Daniel) v3: Squash in the revert and rewrite the commit msg (Daniel) Cc: martin.peres@free.fr Cc: chris@chris-wilson.co.uk Cc: Dave Airlie <airlied@gmail.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by:

[ Upstream commit 465891fe ] The SISLite specification originally defined the context control register with a single field of bits to represent the LISN and also stipulated that the register reset value be 0. The cxlflash driver took advantage of this when programming the LISN for the master contexts via an unconditional write - no other bits were preserved. When unmap support was added, SISLite was updated to define bit 0 of the context control register as a way for the AFU to notify the context owner that unmap operations were supported. Thus the assumptions under which the register is setup changed and the existing unconditional write is clobbering the unmap state for master contexts. This is presently not an issue due to the order in which the context control register is programmed in relation to the unmap bit being queried but should be addressed to avoid a future regression in the event this code is moved elsewhere. To remedy this issue, preserve the bits when programming the LISN field in the context control register. Since the LISN will now be programmed using a read value, assert that the initial state of the LISN field is as described in SISLite (0). Signed-off-by:

This can result in a crash if the recovery thread tries to access this memory. To resolve this issue, the cxlflash remove handler will evaluate the device state and yield to any active reset or probing threads. Signed-off-by:
