98e20e5e - bpfilter: remove bpfilter

Tue, 26 Dec 2023 13:07:42 +0000

bpfilter: remove bpfilterbpfilter was supposed to convert iptables filtering rules intoBPF programs on the fly, from the kernel, through a usermodehelper. The base code for the UMH was introduced in 2018, andcouple of attempts (2, 3) tried to introduce the BPF programgenerate features but were abandoned.bpfilter now sits in a kernel tree unused and unusable, occasionallycausing confusion amongst Linux users (4, 5).As bpfilter is now developed in a dedicated repository on GitHub (6),it was suggested a couple of times this year (LSFMM/BPF 2023,LPC 2023) to remove the deprecated kernel part of the project. Thisis the purpose of this patch.[1]: https://lore.kernel.org/lkml/20180522022230.2492505-1-ast@kernel.org/[2]: https://lore.kernel.org/bpf/20210829183608.2297877-1-me@ubique.spb.ru/#t[3]: https://lore.kernel.org/lkml/20221224000402.476079-1-qde@naccy.de/[4]: https://dxuuu.xyz/bpfilter.html[5]: https://github.com/linuxkit/linuxkit/pull/3904[6]: https://github.com/facebook/bpfilterSigned-off-by: Quentin Deslandes Link: https://lore.kernel.org/r/20231226130745.465988-1-qde@naccy.deSigned-off-by: Alexei Starovoitov List of files: /linux-6.15/net/Makefile

3b3009ea - net/handshake: Create a NETLINK service for handling handshake requests

Mon, 17 Apr 2023 14:32:26 +0000

net/handshake: Create a NETLINK service for handling handshake requestsWhen a kernel consumer needs a transport layer security session, itfirst needs a handshake to negotiate and establish a session. Thisnegotiation can be done in user space via one of the severalexisting library implementations, or it can be done in the kernel.No in-kernel handshake implementations yet exist. In their absence,we add a netlink service that can:a. Notify a user space daemon that a handshake is needed.b. Once notified, the daemon calls the kernel back via this netlink service to get the handshake parameters, including an open socket on which to establish the session.c. Once the handshake is complete, the daemon reports the session status and other information via a second netlink operation. This operation marks that it is safe for the kernel to use the open socket and the security session established there.The notification service uses a multicast group. Each handshakemechanism (eg, tlshd) adopts its own group number so that thehandshake services are completely independent of one another. Thekernel can then tell via netlink_has_listeners() whether a handshakeservice is active and prepared to handle a handshake request.A new netlink operation, ACCEPT, acts like accept(2) in that itinstantiates a file descriptor in the user space daemon's fd table.If this operation is successful, the reply carries the fd number,which can be treated as an open and ready file descriptor.While user space is performing the handshake, the kernel keeps itsmuddy paws off the open socket. A second new netlink operation,DONE, indicates that the user space daemon is finished with thesocket and it is safe for the kernel to use again. The operationalso indicates whether a session was established successfully.Signed-off-by: Chuck Lever Signed-off-by: Jakub Kicinski List of files: /linux-6.15/net/Makefile

5a178186 - net: dsa: replace NETDEV_PRE_CHANGE_HWTSTAMP notifier with a stub

Thu, 06 Apr 2023 11:42:46 +0000

net: dsa: replace NETDEV_PRE_CHANGE_HWTSTAMP notifier with a stubThere was a sort of rush surrounding commit 88c0a6b503b7 ("net: create anetdev notifier for DSA to reject PTP on DSA master"), due to a desireto convert DSA's attempt to deny TX timestamping on a DSA master tosomething that doesn't block the kernel-wide API conversion fromndo_eth_ioctl() to ndo_hwtstamp_set().What was required was a mechanism that did not depend on ndo_eth_ioctl(),and what was provided was a mechanism that did not depend onndo_eth_ioctl(), while at the same time introducing something thatwasn't absolutely necessary - a new netdev notifier.There have been objections from Jakub Kicinski that using notifiers ingeneral when they are not absolutely necessary creates complications tothe control flow and difficulties to maintainers who look at the code.So there is a desire to not use notifiers.In addition to that, the notifier chain gets called even if there is noDSA in the system and no one is interested in applying any restriction.Take the model of udp_tunnel_nic_ops and introduce a stub mechanism,through which net/core/dev_ioctl.c can call into DSA even whenCONFIG_NET_DSA=m.Compared to the code that existed prior to the notifier conversion, akawhat was added in commits:- 4cfab3566710 ("net: dsa: Add wrappers for overloaded ndo_ops")- 3369afba1e46 ("net: Call into DSA netdevice_ops wrappers")this is different because we are not overloading any structnet_device_ops of the DSA master anymore, but rather, we are exposing arather specific functionality which is orthogonal to which API is usedto enable it - ndo_eth_ioctl() or ndo_hwtstamp_set().Also, what is similar is that both approaches use function pointers toget from built-in code to DSA.There is no point in replicating the function pointers towards__dsa_master_hwtstamp_validate() once for every CPU port (dev->dsa_ptr).Instead, it is sufficient to introduce a singleton struct dsa_stubs,built into the kernel, which contains a single function pointer to__dsa_master_hwtstamp_validate().I find this approach preferable to what we had originally, becausedev->dsa_ptr->netdev_ops->ndo_do_ioctl() used to require going throughstruct dsa_port (dev->dsa_ptr), and so, this was incompatible with anyattempts to add any data encapsulation and hide DSA data structures fromthe outside world.Link: https://lore.kernel.org/netdev/20230403083019.120b72fd@kernel.org/Signed-off-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: David S.

Thu, 05 Jan 2023 04:05:17 +0000

devlink: move code to a dedicated directoryThe devlink code is hard to navigate with 13kLoC in one file.I really like the way Michal split the ethtool into per-commandfiles and core. It'd probably be too much to split it all up,but we can at least separate the core parts out of the per-cmdimplementations and put it in a directory so that new commandscan be separate files.Move the code, subsequent commit will do a partial split.Reviewed-by: Jacob Keller Reviewed-by: Jiri Pirko Signed-off-by: Jakub Kicinski List of files: /linux-6.15/net/Makefile

1202cdd6 - Remove DECnet support from kernel

Thu, 18 Aug 2022 00:43:21 +0000

Remove DECnet support from kernelDECnet is an obsolete network protocol that receives more attentionfrom kernel janitors than users. It belongs in computer protocolhistory museum not in Linux kernel.It has been "Orphaned" in kernel since 2010. The iproute2 supportfor DECnet was dropped in 5.0 release. The documentation link onSourceforge says it is abandoned there as well.Leave the UAPI alone to keep userspace programs compiling.This means that there is still an empty neighbour tablefor AF_DECNET.The table of /proc/sys/net entries was updated to matchcurrent directories and reformatted to be alphabetical.Signed-off-by: Stephen Hemminger Acked-by: David Ahern Acked-by: Nikolay Aleksandrov Signed-off-by: David S.

wimax: move out to stagingThere are no known users of this driver as of October 2020, and it willbe removed unless someone turns out to still need it in future releases.According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, therehave been many public wimax networks, but it appears that many of thesehave migrated to LTE or discontinued their service altogether.As most PCs and phones lack WiMAX hardware support, the remainingnetworks tend to use standalone routers. These almost certainlyrun Linux, but not a modern kernel or the mainline wimax driver stack.NetworkManager appears to have dropped userspace support in 2015https://bugzilla.gnome.org/show_bug.cgi?id=747846, thewww.linuxwimax.orgsite had already shut down earlier.WiMax is apparently still being deployed on airport campus networks("AeroMACS"), but in a frequency band that was not supported by the oldIntel 2400m (used in Sandy Bridge laptops and earlier), which is theonly driver using the kernel's wimax stack.Move all files into drivers/staging/wimax, including the uapi headerfiles and documentation, to make it easier to remove it when it getsto that. Only minimal changes are made to the source files, in orderto make it possible to port patches across the move.Also remove the MAINTAINERS entry that refers to a broken mailinglist and website.Acked-by: Jakub Kicinski Acked-by: Greg Kroah-Hartman Acked-By: Inaky Perez-Gonzalez Acked-by: Johannes Berg Suggested-by: Inaky Perez-Gonzalez Signed-off-by: Arnd Bergmann List of files: /linux-6.15/net/Makefile
