landlock: Fix landlock_add_rule(2) documentation
It is not mandatory to pass a file descriptor obtained with the O_PATH flag. Also, replace rule's accesses with ruleset's accesses. Link: https://lore.kernel.org/r/20220506160820.524344-2-mic@digikod.net Cc: stable@vger.kernel.org Signed-off-by: Mickaël Salaün <mic@digikod.net> |

landlock: Format with clang-format
Let's follow a consistent and documented coding style. Everything may not be to our liking but it is better than tacit knowledge. Moreover, this will help maintain style consistency between different developers. This contains only whitespace changes. Automatically formatted with: clang-format-14 -i security/landlock/*.[ch] include/uapi/linux/landlock.h Link: https://lore.kernel.org/r/20220506160513.523257-3-mic@digikod.net Cc: stable@vger.kernel.org Signed-off-by: Mickaël Salaün <mic@digikod.net> |

landlock: Add clang-format exceptions
In preparation to a following commit, add clang-format on and clang-format off stanzas around constant definitions. This enables to keep aligned values, which is much more readable than packed definitions.

ptrace: Cleanups for v5.18
This set of changes removes tracehook.h, moves modification of all of
the ptrace fields inside of siglock to remove races, adds a missing
permission check to ptrace.c
The removal of tracehook.h is quite significant as it has been a major
source of confusion in recent years. Much of that confusion was
around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled
making the semantics clearer).
For people who don't know tracehook.h is a vestiage of an attempt to
implement uprobes like functionality that was never fully merged, and
was later superseeded by uprobes when uprobes was merged. For many
years now we have been removing what tracehook functionaly a little
bit at a time. To the point where now anything left in tracehook.h is
some weird strange thing that is difficult to understand.
Eric W. Biederman (15):
ptrace: Move ptrace_report_syscall into ptrace.h
ptrace/arm: Rename tracehook_report_syscall report_syscall
ptrace: Create ptrace_report_syscall_{entry,exit} in ptrace.h
ptrace: Remove arch_syscall_{enter,exit}_tracehook
ptrace: Remove tracehook_signal_handler
task_work: Remove unnecessary include from posix_timers.h
task_work: Introduce task_work_pending
task_work: Call tracehook_notify_signal from get_signal on all architectures
task_work: Decouple TIF_NOTIFY_SIGNAL and task_work
signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume
resume_user_mode: Move to resume_user_mode.h
tracehook: Remove tracehook.h
ptrace: Move setting/clearing ptrace_message into ptrace_stop
ptrace: Return the signal to continue with from ptrace_stop
Jann Horn (1):
ptrace: Check PTRACE_O_SUSPEND_SECCOMP permission on PTRACE_SEIZE
Yang Li (1):
ptrace: Remove duplicated include in ptrace.c

usercopy: Disable CONFIG_HARDENED_USERCOPY_PAGESPAN
CONFIG_HARDENED_USERCOPY_PAGESPAN has been mostly broken for a while, and it has become hard to ignore with some recent scsi changes[1]. While there is a more complete series to replace it with better checks[2], it should have more soak time in -next. Instead, disable the config now, with the expectation that it will be fully replaced in the next kernel release.

Networking changes for 5.18.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout
the stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower
iTLB pressure and prevents identity mapping huge pages from
getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop
the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called
from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling
of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

ARM driver updates for 5.18
There are a few separately maintained driver subsystems that we merge through
the SoC tree, notable changes are:
- Memory controller updates, mainly for Tegra and Mediatek SoCs,
and clarifications for the memory controller DT bindings
- SCMI firmware interface updates, in particular a new transport based
on OPTEE and support for atomic operations.
- Cleanups to the TEE subsystem, refactoring its memory management
For SoC specific drivers without a separate subsystem, changes include
- Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
Layerscape SoCs.
- Driver support for Microchip SAMA5D29, Tesla FSD, Renesas RZ/G2L,
and Qualcomm SM8450.
- Better power management on Mediatek MT81xx, NXP i.MX8MQ
and older NVIDIA Tegra chips

Pull selinux updates from Paul Moore:
"We've got a number of SELinux patches queued up, the highlights are:
- Fixup the security_fs_context_parse_param() LSM hook so it executes
all of the LSM hook implementations unless a serious error occurs.
We also correct the SELinux hook implementation so that it returns
zero on success.
- In addition to a few SELinux mount option parsing fixes, we
simplified the parsing by moving it earlier in the process.
The logic was that it was unlikely an admin/user would use the new
mount API and not have the policy loaded before passing the SELinux
options.
- Properly fixed the LSM/SELinux/SCTP hooks with the addition of the
security_sctp_assoc_established() hook.
This work was done in conjunction with the netdev folks and should
complete the move of the SCTP labeling from the endpoints to the
associations.
- Fixed a variety of sparse warnings caused by changes in the "__rcu"
markings of some core kernel structures.
- Ensure we access the superblock's LSM security blob using the
stacking-safe accessors.
- Added the ability for the kernel to always allow FIOCLEX and
FIONCLEX if the "ioctl_skip_cloexec" policy capability is
specified.
- Various constifications improvements, type casting improvements,
additional return value checks, and dead code/parameter removal.
- Documentation fixes"

ima: Always return a file measurement in ima_file_hash()
__ima_inode_hash() checks if a digest has been already calculated by looking for the integrity_iint_cache structure associated to the passed inode. Users of ima_file_hash() (e.g. eBPF) might be interested in obtaining the information without having to setup an IMA policy so that the digest is always available at the time they call this function. In addition, they likely expect the digest to be fresh, e.g. recalculated by IMA after a file write. Although getting the digest from the bprm_committed_creds hook (as in the eBPF test) ensures that the digest is fresh, as the IMA hook is executed before that hook, this is not always the case (e.g. for the mmap_file hook). Call ima_collect_measurement() in __ima_inode_hash(), if the file descriptor is available (passed by ima_file_hash()) and the digest is not available/not fresh, and store the file measurement in a temporary integrity_iint_cache structure. This change does not cause memory usage increase, due to using the temporary integrity_iint_cache structure, and due to freeing the ima_digest_data structure inside integrity_iint_cache before exiting from __ima_inode_hash(). For compatibility reasons, the behavior of ima_inode_hash() remains unchanged.

integrity: Introduce a Linux keyring called machine
Many UEFI Linux distributions boot using shim. The UEFI shim provides what is called Machine Owner Keys (MOK). Shim uses both the UEFI Secure Boot DB and MOK keys to validate the next step in the boot chain. The MOK facility can be used to import user generated keys. These keys can be used to sign an end-users development kernel build. When Linux boots, both UEFI Secure Boot DB and MOK keys get loaded in the Linux .platform keyring. Define a new Linux keyring called machine. This keyring shall contain just MOK keys and not the remaining keys in the platform keyring. This new machine keyring will be used in follow on patches. Unlike keys in the platform keyring, keys contained in the machine keyring will be trusted within the kernel if the end-user has chosen to do so.

KEYS: trusted: Avoid calling null function trusted_key_exit
If one loads and unloads the trusted module, trusted_key_exit can be
NULL. Call it through static_call_cond() to avoid a kernel trap.

KEYS: trusted: Fix trusted key backends when building as module
Before this commit the kernel could end up with no trusted key sources
even though both of the currently supported backends (TPM and TEE) were
compiled as modules. This manifested in the trusted key type not being
registered at all.
When checking if a CONFIG_… preprocessor variable is defined we only
test for the builtin (=y) case and not the module (=m) case. By using
the IS_REACHABLE() macro we do test for both cases.

KEYS: fix length validation in keyctl_pkey_params_get_2()
In many cases, keyctl_pkey_params_get_2() is validating the user buffer
lengths against the wrong algorithm properties. Fix it to check against
the correct properties.
Probably this wasn't noticed before because for all asymmetric keys of
the "public_key" subtype, max_data_size == max_sig_size == max_enc_size
== max_dec_size. However, this isn't necessarily true for the
"asym_tpm" subtype (it should be, but it's not strictly validated). Of
course, future key types could have different values as well.

crypto: dh - constify struct dh's pointer members
struct dh contains several pointer members corresponding to DH parameters: ->key, ->p and ->g. A subsequent commit will introduce "dh" wrapping templates of the form "ffdhe2048(dh)", "ffdhe3072(dh)" and so on in order to provide built-in support for the well-known safe-prime ffdhe group parameters specified in RFC 7919. These templates will need to set the group parameter related members of the (serialized) struct dh instance passed to the inner "dh" kpp_alg instance, i.e. ->p and ->g, to some constant, static storage arrays. Turn the struct dh pointer members' types into "pointer to const" in preparation for this.

selinux: shorten the policy capability enum names
The SELinux policy capability enum names are rather long and follow the "POLICYDB_CAPABILITY_XXX format". While the "POLICYDB_" prefix is helpful in tying the enums to other SELinux policy constants, macros, etc. there is no reason why we need to spell out "CAPABILITY" completely. Shorten "CAPABILITY" to "CAP" in order to make things a bit shorter and cleaner. Moving forward, the SELinux policy capability enum names should follow the "POLICYDB_CAP_XXX" format.

These ioctls are equivalent to fcntl(fd, F_SETFD, flags), which SELinux always allows too. Furthermore, a failed FIOCLEX could result in a file descriptor being leaked to a process that should not have access to it.

selinux: fix misuse of mutex_is_locked()
mutex_is_locked() tests whether the mutex is locked *by any task*, while
here we want to test if it is held *by the current task*. To avoid
false/missed WARNINGs, use lockdep_assert_is_held() and
lockdep_assert_is_not_held() instead, which do the right thing (though
they are a no-op if CONFIG_LOCKDEP=n).

KEYS: encrypted: Instantiate key with user-provided decrypted data
For availability and performance reasons master keys often need to be released outside of a Key Management Service (KMS) to clients. It would be beneficial to provide a mechanism where the wrapping/unwrapping of data encryption keys (DEKs) is not dependent on a remote call at runtime yet security is not (or only minimally) compromised. Master keys could be securely stored in the Kernel and be used to wrap/unwrap keys from Userspace. The encrypted.c class supports instantiation of encrypted keys with either an already-encrypted key material, or by generating new key material based on random numbers. This patch defines a new datablob format: [<format>] <master-key name> <decrypted data length> <decrypted data> that allows to inject and encrypt user-provided decrypted data. The decrypted data must be hex-ascii encoded.

security: implement sctp_assoc_established hook in selinux
Do this by extracting the peer labeling per-association logic from
selinux_sctp_assoc_request() into a new helper
selinux_sctp_process_new_assoc() and use this helper in both
selinux_sctp_assoc_request() and selinux_sctp_assoc_established(). This
ensures that the peer labeling behavior as documented in
Documentation/security/SCTP.rst is applied both on the client and server
side:
"""
An SCTP socket will only have one peer label assigned to it. This will be
assigned during the establishment of the first association. Any further
associations on this socket will have their packet peer label compared to
the sockets peer label, and only if they are different will the
``association`` permission be validated. This is validated by checking the
socket peer sid against the received packets peer sid to determine whether
the association should be allowed or denied.
"""
At the same time, it also ensures that the peer label of the association
is set to the correct value, such that if it is peeled off into a new
socket, the socket's peer label will then be set to the association's
peer label, same as it already works on the server side.
While selinux_inet_conn_established() (which we are replacing by
selinux_sctp_assoc_established() for SCTP) only deals with assigning a
peer label to the connection (socket), in case of SCTP we need to also
copy the (local) socket label to the association, so that
selinux_sctp_sk_clone() can then pick it up for the new socket in case
of SCTP peeloff.
Careful readers will notice that the selinux_sctp_process_new_assoc()
helper also includes the "IPv4 packet received over an IPv6 socket"
check, even though it hadn't been in selinux_sctp_assoc_request()
before. While such check is not necessary in
selinux_inet_conn_request() (because struct request_sock's family field
is already set according to the skb's family), here it is needed, as we
don't have request_sock and we take the initial family from the socket.
In selinux_sctp_assoc_established() it is similarly needed as well (and
also selinux_inet_conn_established() already has it).

security: add sctp_assoc_established hook
security_sctp_assoc_established() is added to replace
security_inet_conn_established() called in
sctp_sf_do_5_1E_ca(), so that asoc can be accessed in security
subsystem and save the peer secid to asoc->peer_secid.
