2023-06-27phylink: ReST-ify the phylink_pcs_neg_mode() kdocJakub Kicinski
Stephen reports warnings when rendering phylink kdocs as HTML: include/linux/phylink.h:110: ERROR: Unexpected indentation. include/linux/phylink.h:111: WARNING: Block quote ends without a blank line; unexpected unindent. include/linux/phylink.h:614: WARNING: Inline literal start-string without end-string. include/linux/phylink.h:644: WARNING: Inline literal start-string without end-string. Make phylink_pcs_neg_mode() use a proper list format to fix the first two warnings. The last two warnings, AFAICT, come from the use of shorthand like phylink_mode_*(). Perhaps those should be special-cased at the Sphinx level.

2023-06-27libceph: Partially revert changes to support MSG_SPLICE_PAGESDavid Howells
Fix the mishandling of MSG_DONTWAIT and also reinstates the per-page checking of the source pages (which might have come from a DIO write by userspace) by partially reverting the changes to support MSG_SPLICE_PAGES and doing things a little differently. In messenger_v1: (1) The ceph_tcp_sendpage() is resurrected and the callers reverted to use that. (2) The callers now pass MSG_MORE unconditionally. Previously, they were passing in MSG_MORE|MSG_SENDPAGE_NOTLAST and then degrading that to just MSG_MORE on the last call to ->sendpage(). (3) Make ceph_tcp_sendpage() a wrapper around sendmsg() rather than sendpage(), setting MSG_SPLICE_PAGES if sendpage_ok() returns true on the page. In messenger_v2: (4) Bring back do_try_sendpage() and make the callers use that. (5) Make do_try_sendpage() use sendmsg() for both cases and set MSG_SPLICE_PAGES if sendpage_ok() is set. Fixes: 40a8c17aa770 ("ceph: Use sendmsg(MSG_SPLICE_PAGES) rather than sendpage") Fixes: fa094ccae1e7 ("ceph: Use sendmsg(MSG_SPLICE_PAGES) rather than sendpage()") Reported-by: Ilya Dryomov <idryomov@gmail.com> Link: https://lore.kernel.org/r/CAOi1vP9vjLfk3W+AJFeexC93jqPaPUn2dD_4NrzxwoZTbYfOnw@mail.gmail.com/ Link: https://lore.kernel.org/r/CAOi1vP_Bn918j24S94MuGyn+Gxk212btw7yWeDrRcW1U8pc_BA@mail.gmail.com/ Signed-off-by: David Howells <dhowells@redhat.com> cc: Xiubo Li <xiubli@redhat.com> cc: Jeff Layton <jlayton@kernel.org> cc: Jens Axboe <axboe@kernel.dk> cc: Matthew Wilcox <willy@infradead.org> Link: https://lore.kernel.org/r/3101881.1687801973@warthog.procyon.org.uk/ # v1 Link: https://lore.kernel.org/r/3111635.1687813501@warthog.procyon.org.uk/ # v2 Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Link: https://lore.kernel.org/r/3199652.1687873788@warthog.procyon.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-27net: phy: mscc: fix packet loss due to RGMII delaysVladimir Oltean
Two deadly typos break RX and TX traffic on the VSC8502 PHY using RGMII if phy-mode = "rgmii-id" or "rgmii-txid", and no "tx-internal-delay-ps" override exists. The negative error code from phy_get_internal_delay() does not get overridden with the delay deduced from the phy-mode, and later gets committed to hardware. Also, the rx_delay gets overridden by what should have been the tx_delay.

2023-06-27nfsd: Fix creation time serialization orderTavian Barnes
In nfsd4_encode_fattr(), TIME_CREATE was being written out after all other times. However, they should be written out in an order that matches the bit flags in bmval1, which in this case are #define FATTR4_WORD1_TIME_ACCESS (1UL << 15) #define FATTR4_WORD1_TIME_CREATE (1UL << 18) #define FATTR4_WORD1_TIME_DELTA (1UL << 19) #define FATTR4_WORD1_TIME_METADATA (1UL << 20) #define FATTR4_WORD1_TIME_MODIFY (1UL << 21) so TIME_CREATE should come second. I noticed this on a FreeBSD NFSv4.2 client, which supports creation times. On this client, file times were weirdly permuted. With this patch applied on the server, times looked normal on the client.

2023-06-27nvme-mpath: fix I/O failure with EAGAIN when failing over I/OSagi Grimberg
It is possible that the next available path we failover to, happens to be frozen (for example if it is during connection establishment). If the original I/O was set with NOWAIT, this cause the I/O to unnecessarily fail because the request queue cannot be entered, hence the I/O fails with EAGAIN. The NOWAIT restriction that was originally set for the I/O is no longer relevant or needed because this is the nvme requeue context. Hence we clear the REQ_NOWAIT flag when failing over I/O. This fix a simple test case of nvme controller reset during I/O when the multipath device that has only a single path and I/O fails with "Resource temporarily unavailable" errno. Note that this reproduces with io_uring which by default sets IOCB_NOWAIT by default.

2023-06-27ACPI: EC: Fix acpi_ec_dispatch_gpe()Rafael J. Wysocki
Commit 896e97bf99ec ("ACPI: EC: Clear GPE on interrupt handling only") broke suspend-to-idle at least on Dell XPS13 9360 and 9380. The problem is that acpi_ec_dispatch_gpe() must clear the EC GPE, because the EC GPE handler never runs when the system is in the suspend-to-idle state and if the EC GPE is not cleared by the suspend- to-idle loop, it is never cleared at all which leads to a GPE storm. This causes suspend-to-idle to burn energy instead of saving it which is potentially dangerous (the affected machines heat up rather badly when that happens). Addess this by making acpi_ec_dispatch_gpe() clear the EC GPE as it did before. Fixes: 896e97bf99ec ("ACPI: EC: Clear GPE on interrupt handling only") Tested-by: Rafael J.

2023-06-27vdpa/mlx5: Support interrupt bypassingEli Cohen
Add support for generation of interrupts from the device directly to the VM to the VCPU thus avoiding the overhead on the host CPU. When supported, the driver will attempt to allocate vectors for each data virtqueue. If a vector for a virtqueue cannot be provided it will use the QP mode where notifications go through the driver. In addition, we add a shutdown callback to make sure allocated interrupts are released in case of shutdown to allow clean shutdown.

2023-06-27virtio_pci: Optimize virtio_pci_device structure sizeFeng Liu
Improve the size of the virtio_pci_device structure, which is commonly used to represent a virtio PCI device. A given virtio PCI device can either of legacy type or modern type, with the struct virtio_pci_legacy_device occupying 32 bytes and the struct virtio_pci_modern_device occupying 88 bytes. Make them a union, thereby save 32 bytes of memory as shown by the pahole tool. This improvement is particularly beneficial when dealing with numerous devices, as it helps conserve memory resources. Before the modification, pahole tool reported the following: struct virtio_pci_device { [...] struct virtio_pci_legacy_device ldev; /* 824 32 */ /* --- cacheline 13 boundary (832 bytes) was 24 bytes ago --- */ struct virtio_pci_modern_device mdev; /* 856 88 */ /* XXX last struct has 4 bytes of padding */ [...] /* size: 1056, cachelines: 17, members: 19 */ [...] }; After the modification, pahole tool reported the following: struct virtio_pci_device { [...] union { struct virtio_pci_legacy_device ldev; /* 824 32 */ struct virtio_pci_modern_device mdev; /* 824 88 */ }; /* 824 88 */ [...] /* size: 1024, cachelines: 16, members: 18 */ [...] }; Signed-off-by: Feng Liu <feliu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Message-Id: <20230516135446.16266-1-feliu@nvidia.com> Signed-off-by: Michael S.

2023-06-27efi/libstub: Disable PCI DMA before grabbing the EFI memory mapArd Biesheuvel
Currently, the EFI stub will disable PCI DMA as the very last thing it does before calling ExitBootServices(), to avoid interfering with the firmware's normal operation as much as possible. However, the stub will invoke DisconnectController() on all endpoints downstream of the PCI bridges it disables, and this may affect the layout of the EFI memory map, making it substantially more likely that ExitBootServices() will fail the first time around, and that the EFI memory map needs to be reloaded. This, in turn, increases the likelihood that the slack space we allocated is insufficient (and we can no longer allocate memory via boot services after having called ExitBootServices() once), causing the second call to GetMemoryMap (and therefore the boot) to fail. This makes the PCI DMA disable feature a bit more fragile than it already is, so let's make it more robust, by allocating the space for the EFI memory map after disabling PCI DMA.

2023-06-27ipvlan: Fix return value of ipvlan_queue_xmit()Cambda Zhu
ipvlan_queue_xmit() should return NET_XMIT_XXX, but ipvlan_xmit_mode_l2/l3() returns rx_handler_result_t or NET_RX_XXX in some cases. ipvlan_rcv_frame() will only return RX_HANDLER_CONSUMED in ipvlan_xmit_mode_l2/l3() because 'local' is true. It's equal to NET_XMIT_SUCCESS. But dev_forward_skb() can return NET_RX_SUCCESS or NET_RX_DROP, and returning NET_RX_DROP(NET_XMIT_DROP) will increase both ipvlan and ipvlan->phy_dev drops counter. The skb to forward can be treated as xmitted successfully. This patch makes ipvlan_queue_xmit() return NET_XMIT_SUCCESS for forward skb.

This results in a build failure with a message such as: Cannot find symbol for section 12: .text.perf_callchain_kernel. kernel/events/callchain.o: failed The change to binutils was reverted for v2.38, so this behavior is specific to binutils v2.37: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=c09c8b42021180eee9495bd50d8b35e683d3901b Objtool is able to cope with such sections, so this issue is specific to recordmcount.
