2023-08-14net: phy: Introduce PSGMII PHY interface modeGabor Juhos1-0/+4
The PSGMII interface is similar to QSGMII. The main difference is that the PSGMII interface combines five SGMII lines into a single link while in QSGMII only four lines are combined. Similarly to the QSGMII, this interface mode might also needs special handling within the MAC driver. It is commonly used by Qualcomm with their QCA807x PHY series and modern WiSoC-s. Add definitions for the PHY layer to allow to express this type of connection between the MAC and PHY.

Linux LEDs can be requested to perform hardware accelerated blinking to indicate link, RX, TX etc. Pass the rules for blinking to the PHY driver, if it implements the ops needed to determine if a given pattern can be offloaded, to offload it, and what the current offload is. Additionally implement the op needed to get what device the LED is for.

2023-08-09bpf, sockmap: Fix bug that strp_done cannot be calledXu Kuohai1-0/+1
strp_done is only called when psock->progs.stream_parser is not NULL, but stream_parser was set to NULL by sk_psock_stop_strp(), called by sk_psock_drop() earlier. So, strp_done can never be called. Introduce SK_PSOCK_RX_ENABLED to mark whether there is strp on psock. Change the condition for calling strp_done from judging whether stream_parser is set to judging whether this flag is set. This flag is only set once when strp_init() succeeds, and will never be cleared later.

2023-08-09net: ptp: create a mock-up PTP Hardware Clock driverVladimir Oltean1-0/+38
There are several cases where virtual net devices may benefit from having a PTP clock, and these have to do with testing. I can see at least netdevsim and veth as potential users of a common mock-up PTP hardware clock driver. The proposed idea is to create an object which emulates PTP clock operations on top of the unadjustable CLOCK_MONOTONIC_RAW plus a software-controlled time domain via a timecounter/cyclecounter and then link that PHC to the netdevsim device. The driver is fully functional for its intended purpose, and it successfully passes the PTP selftests. $ cd tools/testing/selftests/ptp/ $ ./phc.sh /dev/ptp2 TEST: settime [ OK ] TEST: adjtime [ OK ] TEST: adjfreq [ OK ] Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Link: https://lore.kernel.org/r/20230807193324.4128292-7-vladimir.oltean@nxp.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-08-09net/mlx5: Expose NIC temperature via hardware monitoring kernel APIAdham Faris2-2/+15
Expose NIC temperature by implementing hwmon kernel API, which turns current thermal zone kernel API to redundant. For each one of the supported and exposed thermal diode sensors, expose the following attributes: 1) Input temperature. 2) Highest temperature. 3) Temperature label: Depends on the firmware capability, if firmware doesn't support sensors naming, the fallback naming convention would be: "sensorX", where X is the HW spec (MTMP register) sensor index. 4) Temperature critical max value: refers to the high threshold of Warning Event. Will be exposed as `tempY_crit` hwmon attribute (RO attribute). For example for ConnectX5 HCA's this temperature value will be 105 Celsius, 10 degrees lower than the HW shutdown temperature). 5) Temperature reset history: resets highest temperature. For example, for dualport ConnectX5 NIC with a single IC thermal diode sensor will have 2 hwmon directories (one for each PCI function) under "/sys/class/hwmon/hwmon[X,Y]". Listing one of the directories above (hwmonX/Y) generates the corresponding output below: $ grep -H -d skip . /sys/class/hwmon/hwmon0/* Output ======================================================================= /sys/class/hwmon/hwmon0/name:mlx5 /sys/class/hwmon/hwmon0/temp1_crit:105000 /sys/class/hwmon/hwmon0/temp1_highest:48000 /sys/class/hwmon/hwmon0/temp1_input:46000 /sys/class/hwmon/hwmon0/temp1_label:asic grep: /sys/class/hwmon/hwmon0/temp1_reset_history: Permission denied In addition, displaying the sensors data via lm_sensors generates the corresponding output below: $ sensors Output ======================================================================= mlx5-pci-0800 Adapter: PCI adapter asic: +46.0°C (crit = +105.0°C, highest = +48.0°C) mlx5-pci-0801 Adapter: PCI adapter asic: +46.0°C (crit = +105.0°C, highest = +48.0°C) CC: Jean Delvare <jdelvare@suse.com> Signed-off-by: Adham Faris <afaris@nvidia.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Reviewed-by: Gal Pressman <gal@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> Acked-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://lore.kernel.org/r/20230807180507.22984-3-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-08-09net: annotate data-races around sock->opsEric Dumazet1-1/+1
IPV6_ADDRFORM socket option is evil, because it can change sock->ops while other threads might read it. Same issue for sk->sk_family being set to AF_INET. Adding READ_ONCE() over sock->ops reads is needed for sockets that might be impacted by IPV6_ADDRFORM. Note that mptcp_is_tcpsk() can also overwrite sock->ops.

2023-08-07bpf: Add support for bpf_get_func_ip helper for uprobe programJiri Olsa1-2/+7
Adding support for bpf_get_func_ip helper for uprobe program to return probed address for both uprobe and return uprobe. We discussed this in [1] and agreed that uprobe can have special use of bpf_get_func_ip helper that differs from kprobe. The kprobe bpf_get_func_ip returns: - address of the function if probe is attach on function entry for both kprobe and return kprobe - 0 if the probe is not attach on function entry The uprobe bpf_get_func_ip returns: - address of the probe for both uprobe and return uprobe The reason for this semantic change is that kernel can't really tell if the probe user space address is function entry. The uprobe program is actually kprobe type program attached as uprobe. One of the consequences of this design is that uprobes do not have its own set of helpers, but share them with kprobes. As we need different functionality for bpf_get_func_ip helper for uprobe, I'm adding the bool value to the bpf_trace_run_ctx, so the helper can detect that it's executed in uprobe context and call specific code. The is_uprobe bool is set as true in bpf_prog_run_array_sleepable, which is currently used only for executing bpf programs in uprobe. Renaming bpf_prog_run_array_sleepable to bpf_prog_run_array_uprobe to address that it's only used for uprobes and that it sets the run_ctx.is_uprobe as suggested by Yafang Shao.

2023-08-07net: skbuff: don't include <net/page_pool/types.h> to <linux/skbuff.h>Alexander Lobakin1-2/+3
Currently, touching <net/page_pool/types.h> triggers a rebuild of more than half of the kernel. That's because it's included in <linux/skbuff.h>. And each new include to page_pool/types.h adds more [useless] data for the toolchain to process per each source file from that pile. In commit 6a5bcd84e886 ("page_pool: Allow drivers to hint on SKB recycling"), Matteo included it to be able to call a couple of functions defined there. Then, in commit 57f05bc2ab24 ("page_pool: keep pp info as long as page pool owns the page") one of the calls was removed, so only one was left. It's the call to page_pool_return_skb_page() in napi_frag_unref(). The function is external and doesn't have any dependencies. Having very niche page_pool_types.h included only for that looks like an overkill. As %PP_SIGNATURE is not local to page_pool.c (was only in the early submissions), nothing holds this function there. Teleport page_pool_return_skb_page() to skbuff.c, just next to the main consumer, skb_pp_recycle(), and rename it to napi_pp_put_page(), as it doesn't work with skbs at all and the former name tells nothing. The #if guards here are only to not compile and have it in the vmlinux when not needed -- both call sites are already guarded. Now, touching page_pool_types.h only triggers rebuilding of the drivers using it and a couple of core networking files.

2023-08-07net: stmmac: correct MAC propagation delayJohannes Zink1-0/+1
The IEEE1588 Standard specifies that the timestamps of Packets must be captured when the PTP message timestamp point (leading edge of first octet after the start of frame delimiter) crosses the boundary between the node and the network. As the MAC latches the timestamp at an internal point, the captured timestamp must be corrected for the additional data transmission latency, as described in the publicly available datasheet [1]. This patch only corrects for the MAC-Internal delay, which can be read out from the MAC_Ingress_Timestamp_Latency register on DWMAC version 5, since the Phy framework currently does not support querying the Phy ingress and egress latency. The Closs Domain Crossing Circuits errors as indicated in [1] are already being accounted in the stmmac_get_tx_hwtstamp() function and are not corrected here. As the Latency varies for different link speeds and MII modes of operation, the correction value needs to be updated on each link state change. As the delay also causes a phase shift in the timestamp counter compared to the rest of the network, this correction will also reduce phase error when generating PPS outputs from the timestamp counter. Since the correction registers may be unavailable on some hardware and no feature bits are documented for dynamically detection of the MAC propagation delay readout, introduce a feature bit to explicitely enable MAC delay Correction in the gluecode driver.

The TPM RNG functionality is not necessary for entropy when the CPU already supports the RDRAND instruction.

2023-08-07net/mlx5: Allocate completion EQs dynamicallyMaher Sanalla1-1/+1
This commit enables the dynamic allocation of EQs at runtime, allowing for more flexibility in managing completion EQs and reducing the memory overhead of driver load. Whenever a CQ is created for a given vector index, the driver will lookup to see if there is an already mapped completion EQ for that vector, if so, utilize it. Otherwise, allocate a new EQ on demand and then utilize it for the CQ completion events. Add a protection lock to the EQ table to protect from concurrent EQ creation attempts. While at it, replace mlx5_vector2irqn()/mlx5_vector2eqn() with mlx5_comp_eqn_get() and mlx5_comp_irqn_get() which will allocate an EQ on demand if no EQ is found for the given vector.

2023-08-07net/mlx5: Add IRQ vector to CPU lookup functionMaher Sanalla1-2/+1
Currently, once driver load completes, IRQ requests were performed for all vectors. However, as we move to support dynamic creation of EQs, this will not be the case as some IRQs will not exist at this stage. Thus, in such case, use the default CPU to IRQ mapping which is the serial mapping based on IRQ vector index. Meaning, the n'th vector gets mapped to the n'th CPU. Introduce an API function mlx5_comp_vector_cpu() that takes an IRQ index and provides the corresponding CPU mapping. It utilizes the existing IRQ affinity if defined, or resorts to the default serialized CPU mapping otherwise.

2023-08-06vfs: get rid of old '->iterate' directory operationLinus Torvalds1-1/+7
All users now just use '->iterate_shared()', which only takes the directory inode lock for reading. Filesystems that never got convered to shared mode now instead use a wrapper that drops the lock, re-takes it in write mode, calls the old function, and then downgrades the lock back to read mode. This way the VFS layer and other callers no longer need to care about filesystems that never got converted to the modern era. The filesystems that use the new wrapper are ceph, coda, exfat, jfs, ntfs, ocfs2, overlayfs, and vboxsf. Honestly, several of them look like they really could just iterate their directories in shared mode and skip the wrapper entirely, but the point of this change is to not change semantics or fix filesystems that haven't been fixed in the last 7+ years, but to finally get rid of the dual iterators.

xdp.h is far more specific and is included in only 67 other files vs netdevice.h's 1538 include sites. Make xdp.h include netdevice.h, instead of the other way around. This decreases the incremental allmodconfig builds size when xdp.h is touched from 5947 to 662 objects. Move bpf_prog_run_xdp() to xdp.h, seems appropriate and filter.h is a mega-header in its own right so it's nice to avoid xdp.h getting included there as well.

2023-08-02net: remove phy_has_hwtstamp() -> phy_mii_ioctl() decision from converted ↵Vladimir Oltean2-0/+20
drivers It is desirable that the new .ndo_hwtstamp_set() API gives more uniformity, less overhead and future flexibility w.r.t. the PHY timestamping behavior. Currently there are some drivers which allow PHY timestamping through the procedure mentioned in Documentation/networking/timestamping.rst. They don't do anything locally if phy_has_hwtstamp() is set, except for lan966x which installs PTP packet traps. Centralize that behavior in a new dev_set_hwtstamp_phylib() code function, which calls either phy_mii_ioctl() for the phylib PHY, or .ndo_hwtstamp_set() of the netdev, based on a single policy (currently simplistic: phy_has_hwtstamp()). Any driver converted to .ndo_hwtstamp_set() will automatically opt into the centralized phylib timestamping policy. Unconverted drivers still get to choose whether they let the PHY handle timestamping or not. Netdev drivers with integrated PHY drivers that don't use phylib presumably don't set dev->phydev, and those will always see HWTSTAMP_SOURCE_NETDEV requests even when converted. The timestamping policy will remain 100% up to them.

This is not directly possible, because phy_mii_ioctl() is a symbol provided under CONFIG_PHYLIB. Do something similar to what was done in DSA in commit 5a17818682cf ("net: dsa: replace NETDEV_PRE_CHANGE_HWTSTAMP notifier with a stub"), and arrange some indirect calls to phy_mii_ioctl() through a stub structure containing function pointers, that's provided by phylib as built-in even when CONFIG_PHYLIB=m, and which phy_init() populates at runtime (module insertion). Note: maybe the ownership of the ethtool_phy_ops singleton is backwards, and the methods exposed by that should be later merged into phylib_stubs.
