2024-02-15evm: Move to LSM infrastructureRoberto Sassu1-0/+1
As for IMA, move hardcoded EVM function calls from various places in the kernel to the LSM infrastructure, by introducing a new LSM named 'evm' (last and always enabled like 'ima'). The order in the Makefile ensures that 'evm' hooks are executed after 'ima' ones. Make EVM functions as static (except for evm_inode_init_security(), which is exported), and register them as hook implementations in init_evm_lsm(). Also move the inline functions evm_inode_remove_acl(), evm_inode_post_remove_acl(), and evm_inode_post_set_acl() from the public evm.h header to evm_main.c. Unlike before (see commit to move IMA to the LSM infrastructure), evm_inode_post_setattr(), evm_inode_post_set_acl(), evm_inode_post_remove_acl(), and evm_inode_post_removexattr() are not executed for private inodes. Finally, add the LSM_ID_EVM case in lsm_list_modules_test.c Signed-off-by: Roberto Sassu <[email protected]> Reviewed-by: Casey Schaufler <[email protected]> Acked-by: Christian Brauner <[email protected]> Reviewed-by: Stefan Berger <[email protected]> Reviewed-by: Mimi Zohar <[email protected]> Acked-by: Mimi Zohar <[email protected]> Signed-off-by: Paul Moore <[email protected]>
2024-02-15ima: Move to LSM infrastructureRoberto Sassu1-0/+1
Move hardcoded IMA function calls (not appraisal-specific functions) from various places in the kernel to the LSM infrastructure, by introducing a new LSM named 'ima' (at the end of the LSM list and always enabled like 'integrity'). Having IMA before EVM in the Makefile is sufficient to preserve the relative order of the new 'ima' LSM in respect to the upcoming 'evm' LSM, and thus the order of IMA and EVM function calls as when they were hardcoded. Make moved functions as static (except ima_post_key_create_or_update(), which is not in ima_main.c), and register them as implementation of the respective hooks in the new function init_ima_lsm(). Select CONFIG_SECURITY_PATH, to ensure that the path-based LSM hook path_post_mknod is always available and ima_post_path_mknod() is always executed to mark files as new, as before the move. A slight difference is that IMA and EVM functions registered for the inode_post_setattr, inode_post_removexattr, path_post_mknod, inode_post_create_tmpfile, inode_post_set_acl and inode_post_remove_acl won't be executed for private inodes. Since those inodes are supposed to be fs-internal, they should not be of interest to IMA or EVM. The S_PRIVATE flag is used for anonymous inodes, hugetlbfs, reiserfs xattrs, XFS scrub and kernel-internal tmpfs files. Conditionally register ima_post_key_create_or_update() if CONFIG_IMA_MEASURE_ASYMMETRIC_KEYS is enabled. Also, conditionally register ima_kernel_module_request() if CONFIG_INTEGRITY_ASYMMETRIC_KEYS is enabled. Finally, add the LSM_ID_IMA case in lsm_list_modules_test.c.

2024-02-16uapi/auxvec: Define AT_HWCAP3 and AT_HWCAP4 aux vector, entriesPeter Bergner1-0/+2
The powerpc toolchain keeps a copy of the HWCAP bit masks in the TCB for fast access by the __builtin_cpu_supports() built-in function. The TCB space for the HWCAP entries - which are created in pairs - is an ABI extension, so waiting to create the space for HWCAP3 and HWCAP4 until they are needed is problematic. Define AT_HWCAP3 and AT_HWCAP4 in the generic uapi header so they can be used in glibc to reserve space in the powerpc TCB for their future use. I scanned through the Linux and GLIBC source codes looking for unused AT_* values and 29 and 30 did not seem to be used, so they are what I went with.

Due to a bug in GuC firmware, Mesa can't enable by default the usage of compute engines in DG2 and newer. A new GuC firmware fixed the issue but until now there was no way for Mesa to know if KMD was running with the fixed GuC version or not, so this uAPI is required.

2024-02-13can: canxl: add virtual CAN network identifier supportOliver Hartkopp2-2/+23
CAN XL data frames contain an 8-bit virtual CAN network identifier (VCID). A VCID value of zero represents an 'untagged' CAN XL frame. To receive and send these optional VCIDs via CAN_RAW sockets a new socket option CAN_RAW_XL_VCID_OPTS is introduced to define/access VCID content: - tx: set the outgoing VCID value by the kernel (one fixed 8-bit value) - tx: pass through VCID values from the user space (e.g. for traffic replay) - rx: apply VCID receive filter (value/mask) to be passed to the user space With the 'tx pass through' option CAN_RAW_XL_VCID_TX_PASS all valid VCID values can be sent, e.g. to replay full qualified CAN XL traffic. The VCID value provided for the CAN_RAW_XL_VCID_TX_SET option will override the VCID value in the struct canxl_frame.prio defined for CAN_RAW_XL_VCID_TX_PASS when both flags are set. With a rx_vcid_mask of zero all possible VCID values (0x00 - 0xFF) are passed to the user space when the CAN_RAW_XL_VCID_RX_FILTER flag is set. Without this flag only untagged CAN XL frames (VCID = 0x00) are delivered to the user space (default). The 8-bit VCID is stored inside the CAN XL prio element (only in CAN XL frames!) to not interfere with other CAN content or the CAN filters provided by the CAN_RAW sockets and kernel infrastruture.

2024-02-12wifi: cfg80211: add support for link id attribute in NL80211_CMD_DEL_STATIONAditya Kumar Singh1-1/+2
Currently whenever NL80211_CMD_DEL_STATION command is called without any MAC address, all stations present on that interface are flushed. However with MLO there is a need to flush such stations only which are using at least a particular link from the AP MLD interface. For example - 2 GHz and 5 GHz are part of an AP MLD. To this interface, following stations are connected - 1. One non-EHT STA on 2 GHz link. 2. One non-EHT STA on 5 GHz link. 3. One Multi-Link STA having 2 GHz and 5 GHz as active links. Now if currently, NL80211_CMD_DEL_STATION is issued by the 2 GHz link without any MAC address, it would flush all station entries. However, flushing of station entry #2 at least is not desireable since it is connected to 5 GHz link alone. Hence, add an option to pass link ID as well in the command so that if link ID is passed, stations using that passed link ID alone would be flushed and others will not. So after this, station entries #1 and #3 alone would be flushed and #2 will remain as it is.

2024-02-08fs: FS_IOC_GETUUIDKent Overstreet1-0/+15
Add a new generic ioctls for querying the filesystem UUID. These are lifted versions of the ext4 ioctls, with one change: we're not using a flexible array member, because UUIDs will never be more than 16 bytes. This patch adds a generic implementation of FS_IOC_GETFSUUID, which reads from super_block->s_uuid. We're not lifting SETFSUUID from ext4 - that can be done on offline filesystems by the people who need it, trying to do it online is just asking for too much trouble.

2024-02-06bonding: Add independent control state machineAahil Awatramani1-0/+1
Add support for the independent control state machine per IEEE 802.1AX-2008 5.4.15 in addition to the existing implementation of the coupled control state machine. Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in the LACP MUX state machine for separated handling of an initial Collecting state before the Collecting and Distributing state. This enables a port to be in a state where it can receive incoming packets while not still distributing. This is useful for reducing packet loss when a port begins distributing before its partner is able to collect. Added new functions such as bond_set_slave_tx_disabled_flags and bond_set_slave_rx_enabled_flags to precisely manage the port's collecting and distributing states. Previously, there was no dedicated method to disable TX while keeping RX enabled, which this patch addresses. Note that the regular flow process in the kernel's bonding driver remains unaffected by this patch. The extension requires explicit opt-in by the user (in order to ensure no disruptions for existing setups) via netlink support using the new bonding parameter coupled_control. The default value for coupled_control is set to 1 so as to preserve existing behaviour.

2024-02-02pidfd: implement PIDFD_THREAD flag for pidfd_open()Oleg Nesterov1-1/+2
With this flag: - pidfd_open() doesn't require that the target task must be a thread-group leader - pidfd_poll() succeeds when the task exits and becomes a zombie (iow, passes exit_notify()), even if it is a leader and thread-group is not empty. This means that the behaviour of pidfd_poll(PIDFD_THREAD, pid-of-group-leader) is not well defined if it races with exec() from its sub-thread; pidfd_poll() can succeed or not depending on whether pidfd_task_exited() is called before or after exchange_tids(). Perhaps we can improve this behaviour later, pidfd_poll() can probably take sig->group_exec_task into account. But this doesn't really differ from the case when the leader exits before other threads (so pidfd_poll() succeeds) and then another thread execs and pidfd_poll() will block again. thread_group_exited() is no longer used, perhaps it can die.
