2022-06-23dm mirror log: clear log bits up to BITS_PER_LONG boundaryMikulas Patocka1-1/+1
Commit 85e123c27d5c ("dm mirror log: round up region bitmap size to BITS_PER_LONG") introduced a regression on 64-bit architectures in the lvm testsuite tests: lvcreate-mirror, mirror-names and vgsplit-operation. If the device is shrunk, we need to clear log bits beyond the end of the device. The code clears bits up to a 32-bit boundary and then calculates lc->sync_count by summing set bits up to a 64-bit boundary (the commit changed that; previously, this boundary was 32-bit too). So, it was using some non-zeroed bits in the calculation and this caused misbehavior. Fix this regression by clearing bits up to BITS_PER_LONG boundary.

2022-06-23dm: fix BLK_STS_DM_REQUEUE handling when dm_io represents split bioMing Lei2-4/+8
Commit 7dd76d1feec7 ("dm: improve bio splitting and associated IO accounting") removed using cloned bio when dm io splitting is needed. Using bio_trim()+bio_inc_remaining() rather than bio_split()+bio_chain() causes multiple dm_io instances to share the same original bio, and it works fine if IOs are completed successfully. But a regression was caused for the case when BLK_STS_DM_REQUEUE is returned from any one of DM's cloned bios (whose dm_io share the same orig_bio). In this BLK_STS_DM_REQUEUE case only the mapped subset of the original bio for the current exact dm_io needs to be re-submitted. However, since the original bio is shared among all dm_io instances, the ->orig_bio actually only represents the last dm_io instance, so requeue can't work as expected. Also when more than one dm_io is requeued, the same original bio is requeued from all dm_io's completion handler, then race is caused. Fix this issue by still allocating one clone bio for completing io only, then io accounting can rely on ->orig_bio being unmodified. This is needed because the dm_io's sector_offset and sectors members are recorded relative to an unmodified ->orig_bio. In the future, we can go back to using bio_trim()+bio_inc_remaining() for dm's io splitting but then delay needing a bio clone only when handling BLK_STS_DM_REQUEUE, but that approach is a bit complicated (so it needs a development cycle): 1) bio clone needs to be done in task context 2) a block interface for unwinding bio is required Fixes: 7dd76d1feec7 ("dm: improve bio splitting and associated IO accounting") Reported-by: Benjamin Marzinski <[email protected]> Signed-off-by: Ming Lei <[email protected]> Signed-off-by: Mike Snitzer <[email protected]>

2022-06-23Revert "printk: add functions to prefer direct printing"Petr Mladek1-2/+0
This reverts commit 2bb2b7b57f81255c13f4395ea911d6bdc70c9fe2. The testing of 5.19 release candidates revealed missing synchronization between early and regular console functionality. It would be possible to start the console kthreads later as a workaround. But it is clear that console lock serialized console drivers between each other. It opens a big area of possible problems that were not considered by people involved in the development and review. printk() is crucial for debugging kernel issues and console output is very important part of it. The number of consoles is huge and a proper review would take some time. As a result it need to be reverted for 5.19.

2022-06-23gpio: grgpio: Fix device removingUwe Kleine-König1-13/+1
If a platform device's remove callback returns non-zero, the device core emits a warning and still removes the device and calls the devm cleanup callbacks. So it's not save to not unregister the gpiochip because on the next request to a GPIO the driver accesses kfree()'d memory. Also if an IRQ triggers, the freed memory is accessed. Instead rely on the GPIO framework to ensure that after gpiochip_remove() all GPIOs are freed and so the corresponding IRQs are unmapped. This is a preparation for making platform remove callbacks return void.

If ports are not turned off in shutdown then runtime suspended self-powered USB devices may survive in U3 link state over S5. During subsequent boot, if firmware sends an IPC command to program the port in DISCONNECT state, it will time out, causing significant delay in the boot time. Turning off roothub port power is also recommended in xhci specification 4.19.4 "Port Power" in the additional note.

2022-06-23xen/gntdev: Avoid blocking in unmap_grant_pages()Demi Marie Obenour2-51/+113
unmap_grant_pages() currently waits for the pages to no longer be used. In https://github.com/QubesOS/qubes-issues/issues/7481, this lead to a deadlock against i915: i915 was waiting for gntdev's MMU notifier to finish, while gntdev was waiting for i915 to free its pages. I also believe this is responsible for various deadlocks I have experienced in the past. Avoid these problems by making unmap_grant_pages async. This requires making it return void, as any errors will not be available when the function returns. Fortunately, the only use of the return value is a WARN_ON(), which can be replaced by a WARN_ON when the error is detected. Additionally, a failed call will not prevent further calls from being made, but this is harmless. Because unmap_grant_pages is now async, the grant handle will be sent to INVALID_GRANT_HANDLE too late to prevent multiple unmaps of the same handle. Instead, a separate bool array is allocated for this purpose. This wastes memory, but stuffing this information in padding bytes is too fragile. Furthermore, it is necessary to grab a reference to the map before making the asynchronous call, and release the reference when the call returns. It is also necessary to guard against reentrancy in gntdev_map_put(), and to handle the case where userspace tries to map a mapping whose contents have not all been freed yet.

This happens because virtnet_freeze() frees the receive_queue completely (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down() and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if netif_running(). However, this should not make any functional difference since the refill work should only be active if the network interface is actually up.

2022-06-22igb: Make DMA faster when CPU is active on the PCIe linkKai-Heng Feng1-7/+5
Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which will be significantly lower when 1) ASPM is disabled or 2) SoC package c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx speed can reach to ~950Mbps. According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC", "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so set it to 1b for "DMA is considered idle when there is no Rx or Tx AND when there are no TLPs indicating that CPU is active detected on the PCIe link (such as the host executes CSR or Configuration register read or write operation)" and performing Tx should also fall under "active CPU on PCIe link" case.

2022-06-22net: dsa: qca8k: reset cpu port on MTU changeChristian Marangi1-1/+21
It was discovered that the Documentation lacks of a fundamental detail on how to correctly change the MAX_FRAME_SIZE of the switch. In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, the switch panics and cease to send any packet. This cause the mgmt ethernet system to not receive any packet (the slow fallback still works) and makes the device not reachable. To recover from this a switch reset is required. To correctly handle this, turn off the cpu ports before changing the MAX_FRAME_SIZE and turn on again after the value is applied.

2022-06-22drm/amdgpu: Adjust logic around GTT size (v3)Alex Deucher1-6/+14
Certain GL unit tests for large textures can cause problems with the OOM killer since there is no way to link this memory to a process. This was originally mitigated (but not necessarily eliminated) by limiting the GTT size. The problem is this limit is often too low for many modern games so just make the limit 1/2 of system memory. The OOM accounting needs to be addressed, but we shouldn't prevent common 3D applications from being usable just to potentially mitigate that corner case. Set default GTT size to max(3G, 1/2 of system ram) by default. v2: drop previous logic and default to 3/4 of ram v3: default to half of ram to align with ttm v4: fix spelling in comment (Kent) Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1942 Reviewed-by: Marek Olšák <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2022-06-22hinic: Replace memcpy() with direct assignmentKees Cook1-3/+1
Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged here for calculating the size of the destination buffer (0x10 instead of 0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with the source and dest being struct fw_section_info_st, so the memcpy should be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's responsibility to figure out. Avoid the whole thing and just do a direct assignment. This results in no change to the executable code.

2022-06-21net: phy: smsc: Disable Energy Detect Power-Down in interrupt modeLukas Wunner1-2/+4
Simon reports that if two LAN9514 USB adapters are directly connected without an intermediate switch, the link fails to come up and link LEDs remain dark. The issue was introduced by commit 1ce8b37241ed ("usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling"). The PHY suffers from a known erratum wherein link detection becomes unreliable if Energy Detect Power-Down is used. In poll mode, the driver works around the erratum by briefly disabling EDPD for 640 msec to detect a neighbor, then re-enabling it to save power. In interrupt mode, no interrupt is signaled if EDPD is used by both link partners, so it must not be enabled at all. We'll recoup the power savings by enabling SUSPEND1 mode on affected LAN95xx chips in a forthcoming commit.

2022-06-21ice: ethtool: Prohibit improper channel config for DCBAnatolii Gerasymenko2-5/+47
Do not allow setting less channels, than Traffic Classes there are via ethtool. There must be at least one channel per Traffic Class. If you set less channels, than Traffic Classes there are, then during ice_vsi_rebuild there would be allocated only the requested amount of tx/rx rings in ice_vsi_alloc_arrays. But later in ice_vsi_setup_q_map there would be requested at least one channel per Traffic Class. This results in setting num_rxq > alloc_rxq and num_txq > alloc_txq. Later, there would be a NULL pointer dereference in ice_vsi_map_rings_to_vectors, because we go beyond of rx_rings or tx_rings arrays. Change ice_set_channels() to return error if you try to allocate less channels, than Traffic Classes there are. Change ice_vsi_setup_q_map() and ice_vsi_setup_q_map_mqprio() to return status code instead of void.

2022-06-21ice: ethtool: advertise 1000M speeds properlyAnatolii Gerasymenko1-1/+38
In current implementation ice_update_phy_type enables all link modes for selected speed. This approach doesn't work for 1000M speeds, because both copper (1000baseT) and optical (1000baseX) standards cannot be enabled at once. Fix this, by adding the function `ice_set_phy_type_from_speed()` for 1000M speeds.

2022-06-21ice: Fix switchdev rules book keepingWojciech Drewek1-0/+1
Adding two filters with same matching criteria ends up with one rule in hardware with act = ICE_FWD_TO_VSI_LIST. In order to remove them properly we have to keep the information about vsi handle which is used in VSI bitmap (ice_adv_fltr_mgmt_list_entry::vsi_list_info::vsi_map).

2022-06-21ice: ignore protocol field in GTP offloadMarcin Szycik1-1/+3
Commit 34a897758efe ("ice: Add support for inner etype in switchdev") added the ability to match on inner ethertype. A side effect of that change is that it is now impossible to add some filters for protocols which do not contain inner ethtype field. tc requires the protocol field to be specified when providing certain other options, e.g. src_ip. This is a problem in case of GTP - when user wants to specify e.g. src_ip, they also need to specify protocol in tc command (otherwise tc fails with: Illegal "src_ip"). Because GTP is a tunnel, the protocol field is treated as inner protocol. GTP does not contain inner ethtype field and the filter cannot be added. To fix this, ignore the ethertype field in case of GTP filters.

2022-06-21dm: do not return early from dm_io_complete if BLK_STS_AGAIN without pollingMike Snitzer1-1/+3
Commit 5291984004edf ("dm: fix bio polling to handle possibile BLK_STS_AGAIN") inadvertently introduced an early return from dm_io_complete() without first queueing the bio to DM if BLK_STS_AGAIN occurs and bio-polling is _not_ being used. Fix this by only returning early from dm_io_complete() if the bio has first been properly queued to DM. Otherwise, the bio will never finish via bio_endio.
