icmp: Add counters for rate limits
There are multiple ICMP rate limiting mechanisms: * Global limits: net.ipv4.icmp_msgs_burst/icmp_msgs_per_sec * v4 per-host limits: net.ipv4.icmp_ratelimit/ratemask * v6 per-host limits: net.ipv6.icmp_ratelimit/ratemask However, when ICMP output is limited, there is no way to tell which limit has been hit or even if the limits are responsible for the lack of ICMP output. Add counters for each of the cases above. As we are within local_bh_disable(), use the __INC stats variant. Example output: # nstat -sz "*RateLimit*" IcmpOutRateLimitGlobal 134 0.0 IcmpOutRateLimitHost 770 0.0 Icmp6OutRateLimitHost 84 0.0 Signed-off-by: Jamie Bainbridge <jamie.bainbridge@gmail.com> Suggested-by: Abhishek Rawal <rawal.abhishek92@gmail.com> Link: https://lore.kernel.org/r/273b32241e6b7fdc5c609e6f5ebc68caf3994342.1674605770.git.jamie.bainbridge@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

inet: Add IP_LOCAL_PORT_RANGE socket option
Users who want to share a single public IP address for outgoing connections
between several hosts traditionally reach for SNAT. However, SNAT requires
state keeping on the node(s) performing the NAT.
A stateless alternative exists, where a single IP address used for egress
can be shared between several hosts by partitioning the available ephemeral
port range. In such a setup:
1. Each host gets assigned a disjoint range of ephemeral ports.
2. Applications open connections from the host-assigned port range.
3. Return traffic gets routed to the host based on both, the destination IP
and the destination port.
An application which wants to open an outgoing connection (connect) from a
given port range today can choose between two solutions:
1. Manually pick the source port by bind()'ing to it before connect()'ing
the socket.
This approach has a couple of downsides:
a) Search for a free port has to be implemented in the user-space. If
the chosen 4-tuple happens to be busy, the application needs to retry
from a different local port number.
Detecting if 4-tuple is busy can be either easy (TCP) or hard
(UDP). In TCP case, the application simply has to check if connect()
returned an error (EADDRNOTAVAIL). That is assuming that the local
port sharing was enabled (REUSEADDR) by all the sockets.
# Assume desired local port range is 60_000-60_511
s = socket(AF_INET, SOCK_STREAM)
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
s.bind(("192.0.2.1", 60_000))
s.connect(("1.1.1.1", 53))
# Fails only if 192.0.2.1:60000 -> 1.1.1.1:53 is busy
# Application must retry with another local port
In case of UDP, the network stack allows binding more than one socket
to the same 4-tuple, when local port sharing is enabled
(REUSEADDR). Hence detecting the conflict is much harder and involves
querying sock_diag and toggling the REUSEADDR flag [1].
b) For TCP, bind()-ing to a port within the ephemeral port range means
that no connecting sockets, that is those which leave it to the
network stack to find a free local port at connect() time, can use
the this port.
IOW, the bind hash bucket tb->fastreuse will be 0 or 1, and the port
will be skipped during the free port search at connect() time.
2. Isolate the app in a dedicated netns and use the use the per-netns
ip_local_port_range sysctl to adjust the ephemeral port range bounds.
The per-netns setting affects all sockets, so this approach can be used
only if:
- there is just one egress IP address, or
- the desired egress port range is the same for all egress IP addresses
used by the application.
For TCP, this approach avoids the downsides of (1). Free port search and
4-tuple conflict detection is done by the network stack:
system("sysctl -w net.ipv4.ip_local_port_range='60000 60511'")
s = socket(AF_INET, SOCK_STREAM)
s.setsockopt(SOL_IP, IP_BIND_ADDRESS_NO_PORT, 1)
s.bind(("192.0.2.1", 0))
s.connect(("1.1.1.1", 53))
# Fails if all 4-tuples 192.0.2.1:60000-60511 -> 1.1.1.1:53 are busy
For UDP this approach has limited applicability. Setting the
IP_BIND_ADDRESS_NO_PORT socket option does not result in local source
port being shared with other connected UDP sockets.
Hence relying on the network stack to find a free source port, limits the
number of outgoing UDP flows from a single IP address down to the number
of available ephemeral ports.
To put it another way, partitioning the ephemeral port range between hosts
using the existing Linux networking API is cumbersome.
To address this use case, add a new socket option at the SOL_IP level,
named IP_LOCAL_PORT_RANGE. The new option can be used to clamp down the
ephemeral port range for each socket individually.
The option can be used only to narrow down the per-netns local port
range. If the per-socket range lies outside of the per-netns range, the
latter takes precedence.
UAPI-wise, the low and high range bounds are passed to the kernel as a pair
of u16 values in host byte order packed into a u32. This avoids pointer
passing.
PORT_LO = 40_000
PORT_HI = 40_511
s = socket(AF_INET, SOCK_STREAM)
v = struct.pack("I", PORT_HI << 16 | PORT_LO)
s.setsockopt(SOL_IP, IP_LOCAL_PORT_RANGE, v)
s.bind(("127.0.0.1", 0))
s.getsockname()
# Local address between ("127.0.0.1", 40_000) and ("127.0.0.1", 40_511),
# if there is a free port. EADDRINUSE otherwise.

Merge tag 'wireless-next-2023-01-23' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next
Kalle Valo says: ==================== wireless-next patches for v6.3 First set of patches for v6.3. The most important change here is that the old Wireless Extension user space interface is not supported on Wi-Fi 7 devices at all. We also added a warning if anyone with modern drivers (ie. cfg80211 and mac80211 drivers) tries to use Wireless Extensions, everyone should switch to using nl80211 interface instead. Static WEP support is removed, there wasn't any driver using that anyway so there's no user impact. Otherwise it's smaller features and fixes as usual. Note: As mt76 had tricky conflicts due to the fixes in wireless tree, we decided to merge wireless into wireless-next to solve them easily. There should not be any merge problems anymore. Major changes: cfg80211 - remove never used static WEP support - warn if Wireless Extention interface is used with cfg80211/mac80211 drivers - stop supporting Wireless Extensions with Wi-Fi 7 devices - support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting rfkill - add GPIO DT support bitfield - add FIELD_PREP_CONST() mt76 - per-PHY LED support rtw89 - support new Bluetooth co-existance version rtl8xxxu - support RTL8188EU * tag 'wireless-next-2023-01-23' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (123 commits) wifi: wireless: deny wireless extensions on MLO-capable devices wifi: wireless: warn on most wireless extension usage wifi: mac80211: drop extra 'e' from ieeee80211... name wifi: cfg80211: Deduplicate certificate loading bitfield: add FIELD_PREP_CONST() wifi: mac80211: add kernel-doc for EHT structure mac80211: support minimal EHT rate reporting on RX wifi: mac80211: Add HE MU-MIMO related flags in ieee80211_bss_conf wifi: mac80211: Add VHT MU-MIMO related flags in ieee80211_bss_conf wifi: cfg80211: Use MLD address to indicate MLD STA disconnection wifi: cfg80211: Support 32 bytes KCK key in GTK rekey offload wifi: cfg80211: Fix extended KCK key length check in nl80211_set_rekey_data() wifi: cfg80211: remove support for static WEP wifi: rtl8xxxu: Dump the efuse only for untested devices wifi: rtl8xxxu: Print the ROM version too wifi: rtw88: Use non-atomic sta iterator in rtw_ra_mask_info_update() wifi: rtw88: Use rtw_iterate_vifs() for rtw_vif_watch_dog_iter() wifi: rtw88: Move register access from rtw_bf_assoc() outside the RCU wifi: rtl8xxxu: Use a longer retry limit of 48 wifi: rtl8xxxu: Report the RSSI to the firmware ... ==================== Link: https://lore.kernel.org/r/20230123103338.330CBC433EF@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: ethtool: netlink: retrieve stats from multiple sources (eMAC, pMAC)
IEEE 802.3-2018 clause 99 defines a MAC Merge sublayer which contains an Express MAC and a Preemptible MAC. Both MACs are hidden to higher and lower layers and visible as a single MAC (packet classification to eMAC or pMAC on TX is done based on priority; classification on RX is done based on SFD). For devices which support a MAC Merge sublayer, it is desirable to retrieve individual packet counters from the eMAC and the pMAC, as well as aggregate statistics (their sum). Introduce a new ETHTOOL_A_STATS_SRC attribute which is part of the policy of ETHTOOL_MSG_STATS_GET and, and an ETHTOOL_A_PAUSE_STATS_SRC which is part of the policy of ETHTOOL_MSG_PAUSE_GET (accepted when ETHTOOL_FLAG_STATS is set in the common ethtool header). Both of these take values from enum ethtool_mac_stats_src, defaulting to "aggregate" in the absence of the attribute. Existing drivers do not need to pay attention to this enum which was added to all driver-facing structures, just the ones which report the MAC merge layer as supported.

net: ethtool: add support for MAC Merge layer
The MAC merge sublayer (IEEE 802.3-2018 clause 99) is one of 2 specifications (the other being Frame Preemption; IEEE 802.1Q-2018 clause 6.7.2), which work together to minimize latency caused by frame interference at TX. The overall goal of TSN is for normal traffic and traffic with a bounded deadline to be able to cohabitate on the same L2 network and not bother each other too much. The standards achieve this (partly) by introducing the concept of preemptible traffic, i.e. Ethernet frames that have a custom value for the Start-of-Frame-Delimiter (SFD), and these frames can be fragmented and reassembled at L2 on a link-local basis. The non-preemptible frames are called express traffic, they are transmitted using a normal SFD, and they can preempt preemptible frames, therefore having lower latency, which can matter at lower (100 Mbps) link speeds, or at high MTUs (jumbo frames around 9K). Preemption is not recursive, i.e. a P frame cannot preempt another P frame. Preemption also does not depend upon priority, or otherwise said, an E frame with prio 0 will still preempt a P frame with prio 7. In terms of implementation, the standards talk about the presence of an express MAC (eMAC) which handles express traffic, and a preemptible MAC (pMAC) which handles preemptible traffic, and these MACs are multiplexed on the same MII by a MAC merge layer. To support frame preemption, the definition of the SFD was generalized to SMD (Start-of-mPacket-Delimiter), where an mPacket is essentially an Ethernet frame fragment, or a complete frame. Stations unaware of an SMD value different from the standard SFD will treat P frames as error frames. To prevent that from happening, a negotiation process is defined. On RX, packets are dispatched to the eMAC or pMAC after being filtered by their SMD. On TX, the eMAC/pMAC classification decision is taken by the 802.1Q spec, based on packet priority (each of the 8 user priority values may have an admin-status of preemptible or express). The MAC Merge layer and the Frame Preemption parameters have some degree of independence in terms of how software stacks are supposed to deal with them. The activation of the MM layer is supposed to be controlled by an LLDP daemon (after it has been communicated that the link partner also supports it), after which a (hardware-based or not) verification handshake takes place, before actually enabling the feature. So the process is intended to be relatively plug-and-play. Whereas FP settings are supposed to be coordinated across a network using something approximating NETCONF. The support contained here is exclusively for the 802.3 (MAC Merge) portions and not for the 802.1Q (Frame Preemption) parts. This API is sufficient for an LLDP daemon to do its job. The FP adminStatus variable from 802.1Q is outside the scope of an LLDP daemon. I have taken a few creative licenses and augmented the Linux kernel UAPI compared to the standard managed objects recommended by IEEE 802.3. These are: - ETHTOOL_A_MM_PMAC_ENABLED: According to Figure 99-6: Receive Processing state diagram, a MAC Merge layer is always supposed to be able to receive P frames. However, this implies keeping the pMAC powered on, which will consume needless power in applications where FP will never be used. If LLDP is used, the reception of an Additional Ethernet Capabilities TLV from the link partner is sufficient indication that the pMAC should be enabled. So my proposal is that in Linux, we keep the pMAC turned off by default and that user space turns it on when needed. - ETHTOOL_A_MM_VERIFY_ENABLED: The IEEE managed object is called aMACMergeVerifyDisableTx. I opted for consistency (positive logic) in the boolean netlink attributes offered, so this is also positive here. Other than the meaning being reversed, they correspond to the same thing. - ETHTOOL_A_MM_MAX_VERIFY_TIME: I found it most reasonable for a LLDP daemon to maximize the verifyTime variable (delay between SMD-V transmissions), to maximize its chances that the LP replies. IEEE says that the verifyTime can range between 1 and 128 ms, but the NXP ENETC stupidly keeps this variable in a 7 bit register, so the maximum supported value is 127 ms. I could have chosen to hardcode this in the LLDP daemon to a lower value, but why not let the kernel expose its supported range directly. - ETHTOOL_A_MM_TX_MIN_FRAG_SIZE: the standard managed object is called aMACMergeAddFragSize, and expresses the "additional" fragment size (on top of ETH_ZLEN), whereas this expresses the absolute value of the fragment size. - ETHTOOL_A_MM_RX_MIN_FRAG_SIZE: there doesn't appear to exist a managed object mandated by the standard, but user space clearly needs to know what is the minimum supported fragment size of our local receiver, since LLDP must advertise a value no lower than that.

net: dcb: add new rewrite table
Add new rewrite table and all the required functions, offload hooks and bookkeeping for maintaining it. The rewrite table reuses the app struct, and the entire set of app selectors. As such, some bookeeping code can be shared between the rewrite- and the APP table. New functions for getting, setting and deleting entries has been added. Apart from operating on the rewrite list, these functions do not emit a DCB_APP_EVENT when the list os modified. The new dcb_getrewr does a lookup based on selector and priority and returns the protocol, so that mappings from priority to protocol, for a given selector and ifindex is obtained. Also, a new nested attribute has been added, that encapsulates one or more app structs. This attribute is used to distinguish the two tables. The dcb_lock used for the APP table is reused for the rewrite table. Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Reviewed-by: Petr Machata <petrm@nvidia.com> Signed-off-by: David S.

Pull block fixes from Jens Axboe:
"The big change here is obviously the revert of the pktcdvd driver
removal. Outside of that, just minor tweaks. In detail:
- Re-instate the pktcdvd driver, which necessitates adding back

- Fix for splitting of a bio marked as NOWAIT, causing either nowait
reads or writes to error with EAGAIN even if parts of the IO

These are (uint64_t)-1 magic values are a userspace ABI, allowing the shared info pages and other enlightenments to be disabled. This isn't a Xen ABI because Xen doesn't let the guest turn these off except with the full SHUTDOWN_soft_reset mechanism.

bpf: Add flag BPF_F_NO_TUNNEL_KEY to bpf_skb_set_tunnel_key()
This patch allows to remove TUNNEL_KEY from the tunnel flags bitmap when using bpf_skb_set_tunnel_key by providing a BPF_F_NO_TUNNEL_KEY flag. On egress, the resulting tunnel header will not contain a tunnel key if the protocol and implementation supports it. At the moment bpf_tunnel_key wants a user to specify a numeric tunnel key. This will wrap the inner packet into a tunnel header with the key bit and value set accordingly. This is problematic when using a tunnel protocol that supports optional tunnel keys and a receiving tunnel device that is not expecting packets with the key bit set. The receiver won't decapsulate and drop the packet. RFC 2890 and RFC 2784 GRE tunnels are examples where this flag is useful. It allows for generating packets, that can be decapsulated by a GRE tunnel device not operating in collect metadata mode or not expecting the key bit set.

removed than added, a nice change. Highlights include:
- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many
USB and other subsystem drivers, that ended up breaking the build.
That will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates
All of these have been in linux-next for a while with no reported
problems"

F2FS_IOC_START_ATOMIC_REPLACE is a variant of the previous atomic write feature which guarantees a per-file atomicity. It would be more efficient than AtomicFile implementation in Android framework. The per-block age-based extent cache implements another type of extent cache in memory which keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately.

Merge tag 'pci-v6.2-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
make more things static.
- Make portdrv bind to Switch Ports that have AER. Previously, if
these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
the Ports couldn't be suspended to low-power states. AER on these
Ports doesn't use interrupts, and the AER driver doesn't need to
claim them.
- Assign PCI domain IDs using ida_alloc(), which makes host bridge
add/remove work better.
Resource management:
- To work better with recent BIOSes that use EfiMemoryMappedIO for
PCI host bridge apertures, remove those regions from the E820 map
(E820 entries normally prevent us from allocating BARs). In v5.19,
we added some quirks to disable E820 checking, but that's not very
maintainable. EfiMemoryMappedIO means the OS needs to map the
region for use by EFI runtime services; it shouldn't prevent OS
from using it.
PCIe native device hotplug:
- Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
PCIe tunneling depends on native PCIe hotplug.
- Enable Command Completed Interrupt only if supported to avoid user
confusion from lspci output that says this is enabled but not
supported.
- Prevent pciehp from binding to Switch Upstream Ports; this happened
because of interaction with acpiphp and caused devices below the
Upstream Port to disappear.
Power management:
- Convert AGP drivers to generic power management. We hope to remove
legacy power management from the PCI core eventually.
Virtualization:
- Fix pci_device_is_present(), which previously always returned
"false" for VFs, causing virtio hangs when unbinding the driver.
Miscellaneous:
- Convert drivers to gpiod API to prepare for dropping some legacy
code.
- Fix DOE fencepost error for the maximum data object length.
Baikal-T1 PCIe controller driver:
- Add driver and DT bindings.
Broadcom STB PCIe controller driver:
- Enable Multi-MSI.
- Delay 100ms after PERST# deassert to allow power and clocks to
stabilize.
- Configure Read Completion Boundary to 64 bytes.
Freescale i.MX6 PCIe controller driver:
- Initialize PHY before deasserting core reset to fix a regression in
v6.0 on boards where the PHY provides the reference.
- Fix imx6sx and imx8mq clock names in DT schema.
Intel VMD host bridge driver:
- Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
SSDs in VT-d pass-through scenarios.
- Disable MSI remapping, which gets re-enabled by firmware during
suspend/resume.
MediaTek PCIe Gen3 controller driver:
- Add MT7986 and MT8195 support.
Qualcomm PCIe controller driver:
- Add SC8280XP/SA8540P basic interconnect support.
Rockchip DesignWare PCIe controller driver:
- Base DT schema on common Synopsys schema.
Synopsys DesignWare PCIe core:
- Collect DT items shared between Root Port and Endpoint (PERST GPIO,
PHY info, clocks, resets, link speed, number of lanes, number of
iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.
- Add dma-ranges support for Root Ports and Endpoints.
- Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
reduce code duplication.
- Add generic names for clocks and resets to encourage more
consistent naming across drivers using DesignWare IP.
- Stop advertising PTM Responder role for Endpoints, which aren't
allowed to be responders.
TI J721E PCIe driver:
- Add j721s2 host mode ID to DT schema.
- Add interrupt properties to DT schema.
Toshiba Visconti PCIe controller driver:
- Fix interrupts array max constraints in DT schema"

Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd implementation from Jason Gunthorpe: "iommufd is the user API to control the IOMMU subsystem as it relates to managing IO page tables that point at user space memory. It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific: - Binding iommu_domain's to PASID/SSID - Userspace IO page tables, for ARM, x86 and S390 - Kernel bypassed invalidation of user page tables - Re-use of the KVM page table in the IOMMU - Dirty page tracking in the IOMMU - Runtime Increase/Decrease of IOPTE size - PRI support with faults resolved in userspace Many of these HW features exist to support VM use cases - for instance the combination of PASID, PRI and Userspace IO Page Tables allows an implementation of DMA Shared Virtual Addressing (vSVA) within a guest. Dirty tracking enables VM live migration with SRIOV devices and PASID support allow creating "scalable IOV" devices, among other things. As these features are fundamental to a VM platform they need to be uniformly exposed to all the driver families that do DMA into VMs, which is currently VFIO and VDPA" For more background, see the extended explanations in Jason's pull request: https://lore.kernel.org/lkml/Y5dzTU8dlmXTbzoJ@nvidia.com/ * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: (62 commits) iommufd: Change the order of MSI setup iommufd: Improve a few unclear bits of code iommufd: Fix comment typos vfio: Move vfio group specific code into group.c vfio: Refactor dma APIs for emulated devices vfio: Wrap vfio group module init/clean code into helpers vfio: Refactor vfio_device open and close vfio: Make vfio_device_open() truly device specific vfio: Swap order of vfio_device_container_register() and open_device() vfio: Set device->group in helper function vfio: Create wrappers for group register/unregister vfio: Move the sanity check of the group to vfio_create_group() vfio: Simplify vfio_create_group() iommufd: Allow iommufd to supply /dev/vfio/vfio vfio: Make vfio_container optionally compiled vfio: Move container related MODULE_ALIAS statements into container.c vfio-iommufd: Support iommufd for emulated VFIO devices vfio-iommufd: Support iommufd for physical VFIO devices vfio-iommufd: Allow iommufd to be used in place of a container fd vfio: Use IOMMU_CAP_ENFORCE_CACHE_COHERENCY for vfio_file_enforced_coherent() ... |
