Previously the net/BPF folks updated the getsockopt code in the network stack to leverage the sockptr_t type to make it easier to pass both kernel and __user pointers, but unfortunately when they did so they didn't convert the LSM hook. While there was/is no immediate risk by not converting the LSM hook, it seems like this is a mistake waiting to happen so this patch proactively does the LSM hook conversion. - Convert vfs_getxattr_alloc() to return an int instead of a ssize_t and cleanup the callers. Internally the function was never going to return anything larger than an int and the callers were doing some very odd things casting the return value; this patch fixes all that and helps bring a bit of sanity to vfs_getxattr_alloc() and its callers. - More verbose, and helpful, LSM debug output when the system is booted with "lsm.debug" on the command line. There are examples in the commit description, but the quick summary is that this patch provides better information about which LSMs are enabled and the ordering in which they are processed. - General comment and kernel-doc fixes and cleanups. * tag 'lsm-pr-20221212' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lsm: Fix description of fs_context_parse_param lsm: Add/fix return values in lsm_hooks.h and fix formatting lsm: Clarify documentation of vm_enough_memory hook reiserfs: Add missing calls to reiserfs_security_free() lsm,fs: fix vfs_getxattr_alloc() return type and caller error paths device_cgroup: Roll back to original exceptions after copy failure LSM: Better reporting of actual LSMs at boot lsm: make security_socket_getpeersec_stream() sockptr_t safe audit: Fix some kernel-doc warnings lsm: remove obsoleted comments for security hooks fs: edit a comment made in bad taste |

As described by Günther [1], the goal of these patches is to work towards a more complete coverage of file system operations that are restrictable with Landlock. The known set of currently unsupported file system operations in Landlock is described at [2]. Out of the operations listed there, truncate is the only one that modifies file contents, so these patches should make it possible to prevent the direct modification of file contents with Landlock. The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the truncate(2) and ftruncate(2) families of syscalls, as well as open(2) with the O_TRUNC flag. This includes usages of creat() in the case where existing regular files are overwritten. Additionally, this introduces a new Landlock security blob associated with opened files, to track the available Landlock access rights at the time of opening the file. This is in line with Unix's general approach of checking the read and write permissions during open(), and associating this previously checked authorization with the opened file. An ongoing patch documents this use case [3]. In order to treat truncate(2) and ftruncate(2) calls differently in an LSM hook, we split apart the existing security_path_truncate hook into security_path_truncate (for truncation by path) and security_file_truncate (for truncation of previously opened files)" Link: https://lore.kernel.org/r/20221018182216.301684-1-gnoack3000@gmail.com [1] Link: https://www.kernel.org/doc/html/v6.1/userspace-api/landlock.html#filesystem-flags [2] Link: https://lore.kernel.org/r/20221209193813.972012-1-mic@digikod.net [3] * tag 'landlock-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: samples/landlock: Document best-effort approach for LANDLOCK_ACCESS_FS_REFER landlock: Document Landlock's file truncation support samples/landlock: Extend sample tool to support LANDLOCK_ACCESS_FS_TRUNCATE selftests/landlock: Test ftruncate on FDs created by memfd_create(2) selftests/landlock: Test FD passing from restricted to unrestricted processes selftests/landlock: Locally define __maybe_unused selftests/landlock: Test open() and ftruncate() in multiple scenarios selftests/landlock: Test file truncation support landlock: Support file truncation landlock: Document init_layer_masks() helper landlock: Refactor check_access_path_dual() into is_access_to_paths_allowed() security: Create file_truncate hook from path_truncate hook |

The origins of this work trace back to v5.19 but it took quite a while to understand the various filesystem specific implementations in sufficient detail and also come up with an acceptable solution. As we discussed and seen multiple times the current state of how posix acls are handled isn't nice and comes with a lot of problems: The current way of handling posix acls via the generic xattr api is error prone, hard to maintain, and type unsafe for the vfs until we call into the filesystem's dedicated get and set inode operations. It is already the case that posix acls are special-cased to death all the way through the vfs. There are an uncounted number of hacks that operate on the uapi posix acl struct instead of the dedicated vfs struct posix_acl. And the vfs must be involved in order to interpret and fixup posix acls before storing them to the backing store, caching them, reporting them to userspace, or for permission checking. Currently a range of hacks and duct tape exist to make this work. As with most things this is really no ones fault it's just something that happened over time. But the code is hard to understand and difficult to maintain and one is constantly at risk of introducing bugs and regressions when having to touch it. Instead of continuing to hack posix acls through the xattr handlers this series builds a dedicated posix acl api solely around the get and set inode operations. Going forward, the vfs_get_acl(), vfs_remove_acl(), and vfs_set_acl() helpers must be used in order to interact with posix acls. They operate directly on the vfs internal struct posix_acl instead of abusing the uapi posix acl struct as we currently do. In the end this removes all of the hackiness, makes the codepaths easier to maintain, and gets us type safety. This series passes the LTP and xfstests suites without any regressions. For xfstests the following combinations were tested: - xfs - ext4 - btrfs - overlayfs - overlayfs on top of idmapped mounts - orangefs - (limited) cifs There's more simplifications for posix acls that we can make in the future if the basic api has made it. A few implementation details: - The series makes sure to retain exactly the same security and integrity module permission checks. Especially for the integrity modules this api is a win because right now they convert the uapi posix acl struct passed to them via a void pointer into the vfs struct posix_acl format to perform permission checking on the mode. There's a new dedicated security hook for setting posix acls which passes the vfs struct posix_acl not a void pointer. Basing checking on the posix acl stored in the uapi format is really unreliable. The vfs currently hacks around directly in the uapi struct storing values that frankly the security and integrity modules can't correctly interpret as evidenced by bugs we reported and fixed in this area. It's not necessarily even their fault it's just that the format we provide to them is sub optimal. - Some filesystems like 9p and cifs need access to the dentry in order to get and set posix acls which is why they either only partially or not even at all implement get and set inode operations. For example, cifs allows setxattr() and getxattr() operations but doesn't allow permission checking based on posix acls because it can't implement a get acl inode operation. Thus, this patch series updates the set acl inode operation to take a dentry instead of an inode argument. However, for the get acl inode operation we can't do this as the old get acl method is called in e.g., generic_permission() and inode_permission(). These helpers in turn are called in various filesystem's permission inode operation. So passing a dentry argument to the old get acl inode operation would amount to passing a dentry to the permission inode operation which we shouldn't and probably can't do. So instead of extending the existing inode operation Christoph suggested to add a new one. He also requested to ensure that the get and set acl inode operation taking a dentry are consistently named. So for this version the old get acl operation is renamed to ->get_inode_acl() and a new ->get_acl() inode operation taking a dentry is added. With this we can give both 9p and cifs get and set acl inode operations and in turn remove their complex custom posix xattr handlers. In the future I hope to get rid of the inode method duplication but it isn't like we have never had this situation. Readdir is just one example. And frankly, the overall gain in type safety and the more pleasant api wise are simply too big of a benefit to not accept this duplication for a while. - We've done a full audit of every codepaths using variant of the current generic xattr api to get and set posix acls and surprisingly it isn't that many places. There's of course always a chance that we might have missed some and if so I'm sure we'll find them soon enough. The crucial codepaths to be converted are obviously stacking filesystems such as ecryptfs and overlayfs. For a list of all callers currently using generic xattr api helpers see [2] including comments whether they support posix acls or not. - The old vfs generic posix acl infrastructure doesn't obey the create and replace semantics promised on the setxattr(2) manpage. This patch series doesn't address this. It really is something we should revisit later though. The patches are roughly organized as follows: (1) Change existing set acl inode operation to take a dentry argument (Intended to be a non-functional change) (2) Rename existing get acl method (Intended to be a non-functional change) (3) Implement get and set acl inode operations for filesystems that couldn't implement one before because of the missing dentry. That's mostly 9p and cifs (Intended to be a non-functional change) (4) Build posix acl api, i.e., add vfs_get_acl(), vfs_remove_acl(), and vfs_set_acl() including security and integrity hooks (Intended to be a non-functional change) (5) Implement get and set acl inode operations for stacking filesystems (Intended to be a non-functional change) (6) Switch posix acl handling in stacking filesystems to new posix acl api now that all filesystems it can stack upon support it. (7) Switch vfs to new posix acl api (semantical change) (8) Remove all now unused helpers (9) Additional regression fixes reported after we merged this into linux-next Thanks to Seth for a lot of good discussion around this and encouragement and input from Christoph" * tag 'fs.acl.rework.v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping: (36 commits) posix_acl: Fix the type of sentinel in get_acl orangefs: fix mode handling ovl: call posix_acl_release() after error checking evm: remove dead code in evm_inode_set_acl() cifs: check whether acl is valid early acl: make vfs_posix_acl_to_xattr() static acl: remove a slew of now unused helpers 9p: use stub posix acl handlers cifs: use stub posix acl handlers ovl: use stub posix acl handlers ecryptfs: use stub posix acl handlers evm: remove evm_xattr_acl_change() xattr: use posix acl api ovl: use posix acl api ovl: implement set acl method ovl: implement get acl method ecryptfs: implement set acl method ecryptfs: implement get acl method ksmbd: use vfs_remove_acl() acl: add vfs_remove_acl() ... |

apparmor: test: make static symbols visible during kunit testing
Use macros, VISIBLE_IF_KUNIT and EXPORT_SYMBOL_IF_KUNIT, to allow static symbols to be conditionally set to be visible during apparmor_policy_unpack_test, which removes the need to include the testing file in the implementation file. Change the namespace of the symbols that are now conditionally visible (by adding the prefix aa_) to avoid confusion with symbols of the same name. Allow the test to be built as a module and namespace the module name from policy_unpack_test to apparmor_policy_unpack_test to improve clarity of the module name. Provide an example of how static symbols can be dealt with in testing.

lsm,fs: fix vfs_getxattr_alloc() return type and caller error paths
The vfs_getxattr_alloc() function currently returns a ssize_t value despite the fact that it only uses int values internally for return values. Fix this by converting vfs_getxattr_alloc() to return an int type and adjust the callers as necessary. As part of these caller modifications, some of the callers are fixed to properly free the xattr value buffer on both success and failure to ensure that memory is not leaked in the failure case.

device_cgroup: Roll back to original exceptions after copy failure
When add the 'a *:* rwm' entry to devcgroup A's whitelist, at first A's
exceptions will be cleaned and A's behavior is changed to
DEVCG_DEFAULT_ALLOW. Then parent's exceptions will be copyed to A's
whitelist. If copy failure occurs, just return leaving A to grant
permissions to all devices. And A may grant more permissions than
parent.
Backup A's whitelist and recover original exceptions after copy
failure.

LSM: Better reporting of actual LSMs at boot
Enhance the details reported by "lsm.debug" in several ways: - report contents of "security=" - report contents of "CONFIG_LSM" - report contents of "lsm=" - report any early LSM details - whitespace-align the output of similar phases for easier visual parsing - change "disabled" to more accurate "skipped" - explain what "skipped" and "ignored" mean in a parenthetical Upgrade the "security= is ignored" warning from pr_info to pr_warn, and include full arguments list to make the cause even more clear. Replace static "Security Framework initializing" pr_info with specific list of the resulting order of enabled LSMs. For example, if the kernel is built with: CONFIG_SECURITY_SELINUX=y CONFIG_SECURITY_APPARMOR=y CONFIG_SECURITY_LOADPIN=y CONFIG_SECURITY_YAMA=y CONFIG_SECURITY_SAFESETID=y CONFIG_SECURITY_LOCKDOWN_LSM=y CONFIG_SECURITY_LANDLOCK=y CONFIG_INTEGRITY=y CONFIG_BPF_LSM=y CONFIG_DEFAULT_SECURITY_APPARMOR=y CONFIG_LSM="landlock,lockdown,yama,loadpin,safesetid,integrity,selinux, smack,tomoyo,apparmor,bpf" Booting without options will show: LSM: initializing lsm=lockdown,capability,landlock,yama,loadpin, safesetid,integrity,selinux,bpf landlock: Up and running.

ima: Fix misuse of dereference of pointer in template_desc_init_fields()
The input parameter @fields is type of struct ima_template_field ***, so
when allocates array memory for @fields, the size of element should be
sizeof(**field) instead of sizeof(*field).
Actually the original code would not cause any runtime error, but it's
better to make it logically right.

selinux: remove the sidtab context conversion indirect calls
The sidtab conversion code has support for multiple context conversion routines through the use of function pointers and indirect calls. However, the reality is that all current users rely on the same conversion routine: convert_context(). This patch does away with this extra complexity and replaces the indirect calls with direct function calls; allowing us to remove a layer of obfuscation and create cleaner, more maintainable code.

ima: Handle -ESTALE returned by ima_filter_rule_match()
IMA relies on the blocking LSM policy notifier callback to update the
LSM based IMA policy rules.
When SELinux update its policies, IMA would be notified and starts
updating all its lsm rules one-by-one. During this time, -ESTALE would
be returned by ima_filter_rule_match() if it is called with a LSM rule
that has not yet been updated. In ima_match_rules(), -ESTALE is not
handled, and the LSM rule is considered a match, causing extra files
to be measured by IMA.
Fix it by re-initializing a temporary rule if -ESTALE is returned by
ima_filter_rule_match(). The origin rule in the rule list would be
updated by the LSM policy notifier callback.

ima: Simplify ima_lsm_copy_rule
Currently ima_lsm_copy_rule() set the arg_p field of the source rule to NULL, so that the source rule could be freed afterward. It does not make sense for this behavior to be inside a "copy" function. So move it outside and let the caller handle this field. ima_lsm_copy_rule() now produce a shallow copy of the original entry including args_p field. Meaning only the lsm.rule and the rule itself should be freed for the original rule. Thus, instead of calling ima_lsm_free_rule() which frees lsm.rule as well as args_p field, free the lsm.rule directly.

capabilities: fix potential memleak on error path from vfs_getxattr_alloc()
In cap_inode_getsecurity(), we will use vfs_getxattr_alloc() to
complete the memory allocation of tmpbuf, if we have completed
the memory allocation of tmpbuf, but failed to call handler->get(...),
there will be a memleak in below logic:
|-- ret = (int)vfs_getxattr_alloc(mnt_userns, ...)
| /* ^^^ alloc for tmpbuf */
|-- value = krealloc(*xattr_value, error + 1, flags)
| /* ^^^ alloc memory */
|-- error = handler->get(handler, ...)
| /* error! */
|-- *xattr_value = value
| /* xattr_value is &tmpbuf (memory leak!) */
So we will try to free(tmpbuf) after vfs_getxattr_alloc() fails to fix it.

Before this commit the callchain was: evm_protect_xattr() -> evm_xattr_change() -> evm_xattr_acl_change() where evm_protect_xattr() was hit from evm_inode_setxattr() and evm_inode_removexattr(). But now we have evm_inode_set_acl() and evm_inode_remove_acl() and have switched over the vfs to rely on the posix acl api so the code isn't hit anymore.

integrity: implement get and set acl hook
The current way of setting and getting posix acls through the generic xattr interface is error prone and type unsafe. The vfs needs to interpret and fixup posix acls before storing or reporting it to userspace. Various hacks exist to make this work. The code is hard to understand and difficult to maintain in it's current form. Instead of making this work by hacking posix acls through xattr handlers we are building a dedicated posix acl api around the get and set inode operations. This removes a lot of hackiness and makes the codepaths easier to maintain. A lot of background can be found in [1]. So far posix acls were passed as a void blob to the security and integrity modules. Some of them like evm then proceed to interpret the void pointer and convert it into the kernel internal struct posix acl representation to perform their integrity checking magic. This is obviously pretty problematic as that requires knowledge that only the vfs is guaranteed to have and has lead to various bugs. Add a proper security hook for setting posix acls and pass down the posix acls in their appropriate vfs format instead of hacking it through a void pointer stored in the uapi format. I spent considerate time in the security module and integrity infrastructure and audited all codepaths. EVM is the only part that really has restrictions based on the actual posix acl values passed through it (e.g., i_mode). Before this dedicated hook EVM used to translate from the uapi posix acl format sent to it in the form of a void pointer into the vfs format. This is not a good thing. Instead of hacking around in the uapi struct give EVM the posix acls in the appropriate vfs format and perform sane permissions checks that mirror what it used to to in the generic xattr hook. IMA doesn't have any restrictions on posix acls. When posix acls are changed it just wants to update its appraisal status to trigger an EVM revalidation. The removal of posix acls is equivalent to passing NULL to the posix set acl hooks. This is the same as before through the generic xattr api.

SELinux: Context system_u:object_r:pssp_rsyslog_log_t:s0:c0 is
not valid (left unmapped).
It was found that within a critical section of spin_lock_irqsave in
sidtab_context_to_sid(), convert_context() (hooked by
sidtab_convert_params.func) might cause the process to sleep via
allocating memory with GFP_KERNEL, which is problematic.
As Ondrej pointed out [1], convert_context()/sidtab_convert_params.func
has another caller sidtab_convert_tree(), which is okay with GFP_KERNEL.
Therefore, fix this problem by adding a gfp_t argument for
convert_context()/sidtab_convert_params.func and pass GFP_KERNEL/_ATOMIC
properly in individual callers.

landlock: Support file truncation
Introduce the LANDLOCK_ACCESS_FS_TRUNCATE flag for file truncation. This flag hooks into the path_truncate, file_truncate and file_alloc_security LSM hooks and covers file truncation using truncate(2), ftruncate(2), open(2) with O_TRUNC, as well as creat(). This change also increments the Landlock ABI version, updates corresponding selftests, and updates code documentation to document the flag. In security/security.c, allocate security blobs at pointer-aligned offsets. This fixes the problem where one LSM's security blob can shift another LSM's security blob to an unaligned address (reported by Nathan Chancellor). The following operations are restricted: open(2): requires the LANDLOCK_ACCESS_FS_TRUNCATE right if a file gets implicitly truncated as part of the open() (e.g. using O_TRUNC). Notable special cases: * open(..., O_RDONLY|O_TRUNC) can truncate files as well in Linux * open() with O_TRUNC does *not* need the TRUNCATE right when it creates a new file. truncate(2) (on a path): requires the LANDLOCK_ACCESS_FS_TRUNCATE right. ftruncate(2) (on a file): requires that the file had the TRUNCATE right when it was previously opened. File descriptors acquired by other means than open(2) (e.g. memfd_create(2)) continue to support truncation with ftruncate(2).

landlock: Refactor check_access_path_dual() into is_access_to_paths_allowed()
Rename check_access_path_dual() to is_access_to_paths_allowed(). Make it return true iff the access is allowed. Calculate the EXDEV/EACCES error code in the one place where it's needed.

security: Create file_truncate hook from path_truncate hook
Like path_truncate, the file_truncate hook also restricts file truncation, but is called in the cases where truncation is attempted on an already-opened file. This is required in a subsequent commit to handle ftruncate() operations differently to truncate() operations.

- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees.

security/keys: Remove inconsistent __user annotation
The declaration of keyring_read does not match the definition (security/keys/keyring.c). In this case the definition is correct because it matches what defined in "struct key_type::read" (linux/key-type.h). Fix the declaration removing the inconsistent __user annotation.

Networking changes for 6.1.
Core ---- - Introduce and use a single page frag cache for allocating small skb heads, clawing back the 10-20% performance regression in UDP flood test from previous fixes. - Run packets which already went thru HW coalescing thru SW GRO. This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF --- - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark. Protocols --------- - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation (MLO) work (802.11be, WiFi 7). - vsock: improve support for SO_RCVLOWAT. - SMC: support SO_REUSEPORT. - Netlink: define and document how to use netlink in a "modern" way. Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API ---------- - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible. It's one of those magic knobs which seemed like a good idea at the time but is too indirect to use in practice. - Support offload of TLS connections with 256 bit keys. New hardware / drivers ---------------------- - Ethernet: - Microchip KSZ9896 6-port Gigabit Ethernet Switch - Renesas Ethernet AVB (EtherAVB-IF) Gen4 SoCs - Analog Devices ADIN1110 and ADIN2111 industrial single pair Ethernet (10BASE-T1L) MAC+PHY. - Rockchip RV1126 Gigabit Ethernet (a version of stmmac IP). - Ethernet SFPs / modules: - RollBall / Hilink / Turris 10G copper SFPs - HALNy GPON module - WiFi: - CYW43439 SDIO chipset (brcmfmac) - CYW89459 PCIe chipset (brcmfmac) - BCM4378 on Apple platforms (brcmfmac) Drivers ------- - CAN: - gs_usb: HW timestamp support - Ethernet PHYs: - lan8814: cable diagnostics - Ethernet NICs: - Intel (100G): - implement control of FCS/CRC stripping - port splitting via devlink - L2TPv3 filtering offload - nVidia/Mellanox: - tunnel offload for sub-functions - MACSec offload, w/ Extended packet number and replay window offload - significantly restructure, and optimize the AF_XDP support, align the behavior with other vendors - Huawei: - configuring DSCP map for traffic class selection - querying standard FEC statistics - querying SerDes lane number via ethtool - Marvell/Cavium: - egress priority flow control - MACSec offload - AMD/SolarFlare: - PTP over IPv6 and raw Ethernet - small / embedded: - ax88772: convert to phylink (to support SFP cages) - altera: tse: convert to phylink - ftgmac100: support fixed link - enetc: standard Ethtool counters - macb: ZynqMP SGMII dynamic configuration support - tsnep: support multi-queue and use page pool - lan743x: Rx IP & TCP checksum offload - igc: add xdp frags support to ndo_xdp_xmit - Ethernet high-speed switches: - Marvell (prestera): - support SPAN port features (traffic mirroring) - nexthop object offloading - Microchip (sparx5): - multicast forwarding offload - QoS queuing offload (tc-mqprio, tc-tbf, tc-ets) - Ethernet embedded switches: - Marvell (mv88e6xxx): - support RGMII cmode - NXP (felix): - standardized ethtool counters - Microchip (lan966x): - QoS queuing offload (tc-mqprio, tc-tbf, tc-cbs, tc-ets) - traffic policing and mirroring - link aggregation / bonding offload - QUSGMII PHY mode support - Qualcomm 802.11ax WiFi (ath11k): - cold boot calibration support on WCN6750 - support to connect to a non-transmit MBSSID AP profile - enable remain-on-channel support on WCN6750 - Wake-on-WLAN support for WCN6750 - support to provide transmit power from firmware via nl80211 - support to get power save duration for each client - spectral scan support for 160 MHz - MediaTek WiFi (mt76): - WiFi-to-Ethernet bridging offload for MT7986 chips - RealTek WiFi (rtw89): - P2P support Signed-off-by: Jakub Kicinski <kuba@kernel.org> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE6jPA+I1ugmIBA4hXMUZtbf5SIrsFAmM7vtkACgkQMUZtbf5S Irvotg//dmh53rC+UMKO3OgOqPlSMnaqzbUdDEfN6mj4Mpox7Csb8zERVURHhBHY fvlXWsDgxmvgTebI5fvNC5+f1iW5xcqgJV2TWnNmDOKWwvQwb6qQfgixVmunvkpe IIukMXYt0dAf9bXeeEfbNXcCb85cPwB76stX0tMV6BX7osp3T0TL1fvFk0NJkL0j TeydLad/yAQtPb4TbeWYjNDoxPVDf0cVpUrevLGmWE88UMYmgTqPze+h1W5Wri52 bzjdLklY/4cgcIZClHQ6F9CeRWqEBxvujA5Hj/cwOcn/ptVVJWUGi7sQo3sYkoSs HFu+F8XsTec14kGNC0Ab40eVdqs5l/w8+E+4jvgXeKGOtVns8DwoiUIzqXpyty89 Ib04mffrwWNjFtHvo/kIsNwP05X2PGE9HUHfwsTUfisl/ASvMmQp7D7vUoqQC/4B AMVzT5qpjkmfBHYQQGuw8FxJhMeAOjC6aAo6censhXJyiUhIfleQsN0syHdaNb8q 9RZlhAgQoVb6ZgvBV8r8unQh/WtNZ3AopwifwVJld2unsE/UNfQy2KyqOWBES/zf LP9sfuX0JnmHn8s1BQEUMPU1jF9ZVZCft7nufJDL6JhlAL+bwZeEN4yCiAHOPZqE ymSLHI9s8yWZoNpuMWKrI9kFexVnQFKmA3+quAJUcYHNMSsLkL8= =Gsio -----END PGP SIGNATURE----- Merge tag 'net-next-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core: - Introduce and use a single page frag cache for allocating small skb heads, clawing back the 10-20% performance regression in UDP flood test from previous fixes. - Run packets which already went thru HW coalescing thru SW GRO.

Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API: - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible. It's one of those magic knobs which seemed like a good idea at the time but is too indirect to use in practice. - Support offload of TLS connections with 256 bit keys.
