git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux Pull landlock updates from Mickaël Salaün: "A Landlock ruleset can now handle two new access rights: LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When handled, the related actions are denied unless explicitly allowed by a Landlock network rule for a specific port. The related patch series has been reviewed for almost two years, it has evolved a lot and we now have reached a decent design, code and testing. The refactored kernel code and the new test helpers also bring the foundation to support more network protocols. Test coverage for security/landlock is 92.4% of 710 lines according to gcc/gcov-13, and it was 93.1% of 597 lines before this series. The decrease in coverage is due to code refactoring to make the ruleset management more generic (i.e. dealing with inodes and ports) that also added new WARN_ON_ONCE() checks not possible to test from user space. syzkaller has been updated accordingly [4], and such patched instance (tailored to Landlock) has been running for a month, covering all the new network-related code [5]" Link: https://lore.kernel.org/r/20231026014751.414649-1-konstantin.meskhidze@huawei.com [1] Link: https://lore.kernel.org/r/CAHC9VhS1wwgH6NNd+cJz4MYogPiRV8NyPDd1yj5SpaxeUB4UVg@mail.gmail.com [2] Link: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next-history.git/commit/?id=c8dc5ee69d3a [3] Link: https://github.com/google/syzkaller/pull/4266 [4] Link: https://storage.googleapis.com/syzbot-assets/82e8608dec36/ci-upstream-linux-next-kasan-gce-root-ab577164.html#security%2flandlock%2fnet.c [5] * tag 'landlock-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/landlock: Add tests for FS topology changes with network rules landlock: Document network support samples/landlock: Support TCP restrictions selftests/landlock: Add network tests selftests/landlock: Share enforce_ruleset() helper landlock: Support network rules with TCP bind and connect landlock: Refactor landlock_add_rule() syscall landlock: Refactor layer helpers landlock: Move and rename layer helpers landlock: Refactor merge/inherit_ruleset helpers landlock: Refactor landlock_find_rule/insert_rule helpers landlock: Allow FS topology changes for domains without such rule type landlock: Make ruleset's access masks more generic

2023-10-26landlock: Allow FS topology changes for domains without such rule typeMickaël Salaün1-3/+3
Allow mount point and root directory changes when there is no filesystem rule tied to the current Landlock domain. This doesn't change anything for now because a domain must have at least a (filesystem) rule, but this will change when other rule types will come. For instance, a domain only restricting the network should have no impact on filesystem restrictions. Add a new get_current_fs_domain() helper to quickly check filesystem rule existence for all filesystem LSM hooks. Remove unnecessary inlining.

2023-10-20netlink: add variable-length / auto integersJakub Kicinski1-2/+16
We currently push everyone to use padding to align 64b values in netlink. Un-padded nla_put_u64() doesn't even exist any more. The story behind this possibly start with this thread: https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/ where DaveM was concerned about the alignment of a structure containing 64b stats. If user space tries to access such struct directly: struct some_stats *stats = nla_data(attr); printf("A: %llu", stats->a); lack of alignment may become problematic for some architectures. These days we most often put every single member in a separate attribute, meaning that the code above would use a helper like nla_get_u64(), which can deal with alignment internally. Even for arches which don't have good unaligned access - access aligned to 4B should be pretty efficient. Kernel and well known libraries deal with unaligned input already. Padded 64b is quite space-inefficient (64b + pad means at worst 16B per attr vs 32b which takes 8B). It is also more typing: if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING, value, NETDEV_A_SOMETHING_PAD)) Create a new attribute type which will use 32 bits at netlink level if value is small enough (probably most of the time?), and (4B-aligned) 64 bits otherwise. Kernel API is just: if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value)) Calling this new type "just" sint / uint with no specific size will hopefully also make people more comfortable with using it. Currently telling people "don't use u8, you may need the bits, and netlink will round up to 4B, anyway" is the #1 comment we give to newcomers. In terms of netlink layout it looks like this: 0 4 8 12 16 32b: [nlattr][ u32 ] 64b: [ pad ][nlattr][ u64 ] uint(32) [nlattr][ u32 ] uint(64) [nlattr][ u64 ] Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

Several compile-mode dependecies to select between ISP2400 and ISP2401 are now solved in runtime - a new ipu-bridge logic was added to work with IVSC MEI drivers - venus driver gained better support for new VPU versions - the v4l core async framework has gained lots of improvements and cleanups - lots of other cleanups, improvements and driver fixes * tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (358 commits) media: ivsc: Add ACPI dependency media: bttv: convert to vb2 media: bttv: use audio defaults for winfast2000 media: bttv: refactor bttv_set_dma() media: bttv: move vbi_skip/vbi_count out of buffer media: bttv: remove crop info from bttv_buffer media: bttv: remove tvnorm field from bttv_buffer media: bttv: remove format field from bttv_buffer media: bttv: move do_crop flag out of bttv_fh media: bttv: copy vbi_fmt from bttv_fh media: bttv: copy vid fmt/width/height from fh media: bttv: radio use v4l2_fh instead of bttv_fh media: bttv: replace BUG with WARN_ON media: bttv: use video_drvdata to get bttv media: i2c: rdacm21: Fix uninitialized value media: coda: Remove duplicated include media: vivid: fix the racy dev->radio_tx_rds_owner media: i2c: ccs: Check rules is non-NULL media: i2c: ds90ub960: Fix PLL config for 1200 MHz CSI rate media: i2c: ds90ub953: Fix use of uninitialized variables ...

Increasing the default value allows for better BIG TCP performances - Reduce compound page head access for zero-copy data transfers - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible - Threaded NAPI improvements, adding defer skb free support and unneeded softirq avoidance - Address dst_entry reference count scalability issues, via false sharing avoidance and optimize refcount tracking - Add lockless accesses annotation to sk_err[_soft] - Optimize again the skb struct layout - Extends the skb drop reasons to make it usable by multiple subsystems - Better const qualifier awareness for socket casts BPF: - Add skb and XDP typed dynptrs which allow BPF programs for more ergonomic and less brittle iteration through data and variable-sized accesses - Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward - Add more precise memory usage reporting for all BPF map types - Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params - Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton - Bigger batch of BPF verifier improvements to prepare for upcoming BPF open-coded iterators allowing for less restrictive looping capabilities - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF programs to NULL-check before passing such pointers into kfunc - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in local storage maps - Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps - Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree - Add BPF verifier support for ST instructions in convert_ctx_access() which will help new -mcpu=v4 clang flag to start emitting them - Add ARM32 USDT support to libbpf - Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations Protocols: - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value indicates the provenance of the IP address - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition - Add the handshake upcall mechanism, allowing the user-space to implement generic TLS handshake on kernel's behalf - Bridge: support per-{Port, VLAN} neighbor suppression, increasing resilience to nodes failures - SCTP: add support for Fair Capacity and Weighted Fair Queueing schedulers - MPTCP: delay first subflow allocation up to its first usage. This will allow for later better LSM interaction - xfrm: Remove inner/outer modes from input/output path. These are not needed anymore - WiFi: - reduced neighbor report (RNR) handling for AP mode - HW timestamping support - support for randomized auth/deauth TA for PASN privacy - per-link debugfs for multi-link - TC offload support for mac80211 drivers - mac80211 mesh fast-xmit and fast-rx support - enable Wi-Fi 7 (EHT) mesh support Netfilter: - Add nf_tables 'brouting' support, to force a packet to be routed instead of being bridged - Update bridge netfilter and ovs conntrack helpers to handle IPv6 Jumbo packets properly, i.e. fetch the packet length from hop-by-hop extension header. This is needed for BIT TCP support - The iptables 32bit compat interface isn't compiled in by default anymore - Move ip(6)tables builtin icmp matches to the udptcp one. This has the advantage that icmp/icmpv6 match doesn't load the iptables/ip6tables modules anymore when iptables-nft is used - Extended netlink error report for netdevice in flowtables and netdev/chains. Allow for incrementally add/delete devices to netdev basechain. Allow to create netdev chain without device Driver API: - Remove redundant Device Control Error Reporting Enable, as PCI core has already error reporting enabled at enumeration time - Move Multicast DB netlink handlers to core, allowing devices other then bridge to use them - Allow the page_pool to directly recycle the pages from safely localized NAPI - Implement lockless TX queue stop/wake combo macros, allowing for further code de-duplication and sanitization - Add YNL support for user headers and struct attrs - Add partial YNL specification for devlink - Add partial YNL specification for ethtool - Add tc-mqprio and tc-taprio support for preemptible traffic classes - Add tx push buf len param to ethtool, specifies the maximum number of bytes of a transmitted packet a driver can push directly to the underlying device - Add basic LED support for switch/phy - Add NAPI documentation, stop relaying on external links - Convert dsa_master_ioctl() to netdev notifier.
