The kernel-doc script identified multiple issues in ieee80211.h, so fix them.

2023-08-20net: selectively purge error queue in IP_RECVERR / IPV6_RECVERREric Dumazet
Setting IP_RECVERR and IPV6_RECVERR options to zero currently purges the socket error queue, which was probably not expected for zerocopy and tx_timestamp users. I discovered this issue while preparing commit 6b5f43ea0815 ("inet: move inet->recverr to inet->inet_flags"), I presume this change does not need to be backported to stable kernels. Add skb_errqueue_purge() helper to purge error messages only.

Unfortunately, a VM can run a different kernel than the host, meaning that those structures are sorta ABI. However, it is possible to have proper flex arrays + struct_size() calculations and still send the very same messages with the same sizes. The common rule is: elem[1] -> elem[] size = struct_size() + <difference between the old and the new msg size> The "old" size in the current code is calculated 3 different ways for 10 virtchnl structures total. Each commit addresses one of the ways cumulatively instead of per-structure. I was planning to send it to -net initially, but given that virtchnl was renamed from i40evf and got some fat style cleanup commits in the past, it's not very straightforward to even pick appropriate SHAs, not speaking of automatic portability. I may send manual backports for a couple of the latest supported kernels later on if anyone needs it at all.

2023-08-16virtchnl: fix fake 1-elem arrays for structures allocated as `nents`Alexander Lobakin
Finally, fix 3 structures which are allocated technically correctly, i.e. the calculated size equals to the one that struct_size() would return, except for sizeof(). For &virtchnl_vlan_filter_list_v2, use the same approach when there are no enough space as taken previously for &virtchnl_vlan_filter_list, i.e. let the maximum size be calculated automatically instead of trying to guestimate it using maths.

2023-08-16virtchnl: fix fake 1-elem arrays in structures allocated as `nents + 1`Alexander Lobakin
There are five virtchnl structures, which are allocated and checked in the code as `nents + 1`, meaning that they always have memory for one excessive element regardless of their actual number. This comes from that their sizeof() includes space for 1 element and then they get allocated via struct_size() or its open-coded equivalents, passing the actual number of elements. Expand virtchnl_struct_size() to handle such structures and replace those 1-elem arrays with proper flex ones. Also fix several places which open-code %IAVF_VIRTCHNL_VF_RESOURCE_SIZE. Finally, let the virtchnl_ether_addr_list size be computed automatically when there's no enough space for the whole list, otherwise we have to open-code reverse struct_size() logics.

2023-08-16virtchnl: fix fake 1-elem arrays in structs allocated as `nents + 1` - 1Alexander Lobakin
The two most problematic virtchnl structures are virtchnl_rss_key and virtchnl_rss_lut. Their "flex" arrays have the type of u8, thus, when allocating / checking, the actual size is calculated as `sizeof + nents - 1 byte`. But their sizeof() is not 1 byte larger than the size of such structure with proper flex array, it's two bytes larger due to the padding. That said, their size is always 1 byte larger unless there are no tail elements -- then it's +2 bytes. Add virtchnl_struct_size() macro which will handle this case (and later other cases as well). Make its calling conv the same as we call struct_size() to allow it to be drop-in, even though it's unlikely to become possible to switch to generic API. The macro will calculate a proper size of a structure with a flex array at the end, so that it becomes transparent for the compilers, but add the difference from the old values, so that the real size of sorta-ABI-messages doesn't change. Use it on the allocation side in IAVF and the receiving side (defined as static inline in virtchnl.h) for the mentioned two structures.

2023-08-16net-memcg: Fix scope of sockmem pressure indicatorsAbel Wu
Now there are two indicators of socket memory pressure sit inside struct mem_cgroup, socket_pressure and tcpmem_pressure, indicating memory reclaim pressure in memcg->memory and ->tcpmem respectively. When in legacy mode (cgroupv1), the socket memory is charged into ->tcpmem which is independent of ->memory, so socket_pressure has nothing to do with socket's pressure at all. Things could be worse by taking socket_pressure into consideration in legacy mode, as a pressure in ->memory can lead to premature reclamation/throttling in socket. While for the default mode (cgroupv2), the socket memory is charged into ->memory, and ->tcpmem/->tcpmem_pressure are simply not used. So {socket,tcpmem}_pressure are only used in default/legacy mode respectively for indicating socket memory pressure. This patch fixes the pieces of code that make mixed use of both.

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.

2023-08-12locking: remove spin_lock_prefetchMateusz Guzik
The only remaining consumer is new_inode, where it showed up in 2001 as commit c37fa164f793 ("v2.4.9.9 -> v2.4.9.10") in a historical repo [1] with a changelog which does not mention it. Since then the line got only touched up to keep compiling. While it may have been of benefit back in the day, it is guaranteed to at best not get in the way in the multicore setting -- as the code performs *a lot* of work between the prefetch and actual lock acquire, any contention means the cacheline is already invalid by the time the routine calls spin_lock(). It adds spurious traffic, for short. On top of it prefetch is notoriously tricky to use for single-threaded purposes, making it questionable from the get go. As such, remove it. I admit upfront I did not see value in benchmarking this change, but I can do it if that is deemed appropriate. Removal from new_inode and of the entire thing are in the same patch as requested by Linus, so whatever weird looks can be directed at that guy.

2023-08-09bpf, sockmap: Fix bug that strp_done cannot be calledXu Kuohai
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 Oltean
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 Faris
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 Dumazet
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.

2023-08-09block: don't make REQ_POLLED imply REQ_NOWAITJens Axboe
Normally these two flags do go together, as the issuer of polled IO generally cannot wait for resources that will get freed as part of IO completion. This is because that very task is the one that will complete the request and free those resources, hence that would introduce a deadlock. But it is possible to have someone else issue the polled IO, eg via io_uring if the request is punted to io-wq. For that case, it's fine to have the task block on IO submission, as it is not the same task that will be completing the IO. It's completely up to the caller to ask for both polled and nowait IO separately! If we don't allow polled IO where IOCB_NOWAIT isn't set in the kiocb, then we can run into repeated -EAGAIN submissions and not make any progress.

2023-08-07bpf: Add support for bpf_get_func_ip helper for uprobe programJiri Olsa
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.
