2023-10-27net/tcp: Allow asynchronous delete for TCP-AO keys (MKTs)Dmitry Safonov1-1/+2
Delete becomes very, very fast - almost free, but after setsockopt() syscall returns, the key is still alive until next RCU grace period. Which is fine for listen sockets as userspace needs to be aware of setsockopt(TCP_AO) and accept() race and resolve it with verification by getsockopt() after TCP connection was accepted. The benchmark results (on non-loaded box, worse with more RCU work pending): > ok 33 Worst case delete 16384 keys: min=5ms max=10ms mean=6.93904ms stddev=0.263421 > ok 34 Add a new key 16384 keys: min=1ms max=4ms mean=2.17751ms stddev=0.147564 > ok 35 Remove random-search 16384 keys: min=5ms max=10ms mean=6.50243ms stddev=0.254999 > ok 36 Remove async 16384 keys: min=0ms max=0ms mean=0.0296107ms stddev=0.0172078 Co-developed-by: Francesco Ruggeri <[email protected]> Signed-off-by: Francesco Ruggeri <[email protected]> Co-developed-by: Salam Noureddine <[email protected]> Signed-off-by: Salam Noureddine <[email protected]> Signed-off-by: Dmitry Safonov <[email protected]> Acked-by: David Ahern <[email protected]> Signed-off-by: David S.

2023-10-27net/tcp: Add TCP-AO getsockopt()sDmitry Safonov2-14/+61
Introduce getsockopt(TCP_AO_GET_KEYS) that lets a user get TCP-AO keys and their properties from a socket. The user can provide a filter to match the specific key to be dumped or ::get_all = 1 may be used to dump all keys in one syscall. Add another getsockopt(TCP_AO_INFO) for providing per-socket/per-ao_info stats: packet counters, Current_key/RNext_key and flags like ::ao_required and ::accept_icmps.

2023-10-27net/tcp: Add option for TCP-AO to (not) hash headerDmitry Safonov1-0/+5
Provide setsockopt() key flag that makes TCP-AO exclude hashing TCP header for peers that match the key.

2023-10-27net/tcp: Ignore specific ICMPs for TCP-AO connectionsDmitry Safonov3-2/+14
Similarly to IPsec, RFC5925 prescribes: ">> A TCP-AO implementation MUST default to ignore incoming ICMPv4 messages of Type 3 (destination unreachable), Codes 2-4 (protocol unreachable, port unreachable, and fragmentation needed -- ’hard errors’), and ICMPv6 Type 1 (destination unreachable), Code 1 (administratively prohibited) and Code 4 (port unreachable) intended for connections in synchronized states (ESTABLISHED, FIN-WAIT-1, FIN- WAIT-2, CLOSE-WAIT, CLOSING, LAST-ACK, TIME-WAIT) that match MKTs." A selftest (later in patch series) verifies that this attack is not possible in this TCP-AO implementation.

2023-10-27net/tcp: Verify inbound TCP-AO signed segmentsDmitry Safonov3-2/+82
Now there is a common function to verify signature on TCP segments: tcp_inbound_hash(). It has checks for all possible cross-interactions with MD5 signs as well as with unsigned segments. The rules from RFC5925 are: (1) Any TCP segment can have at max only one signature. (2) TCP connections can't switch between using TCP-MD5 and TCP-AO. (3) TCP-AO connections can't stop using AO, as well as unsigned connections can't suddenly start using AO.

2023-10-27net/tcp: Add tcp_parse_auth_options()Dmitry Safonov3-2/+45
Introduce a helper that: (1) shares the common code with TCP-MD5 header options parsing (2) looks for hash signature only once for both TCP-MD5 and TCP-AO (3) fails with -EEXIST if any TCP sign option is present twice, see RFC5925 (2.2): ">> A single TCP segment MUST NOT have more than one TCP-AO in its options sequence.

2023-10-27net/tcp: Add TCP-AO sign to outgoing packetsDmitry Safonov2-0/+87
Using precalculated traffic keys, sign TCP segments as prescribed by RFC5925. Per RFC, TCP header options are included in sign calculation: "The TCP header, by default including options, and where the TCP checksum and TCP-AO MAC fields are set to zero, all in network- byte order." (5.1.3) tcp_ao_hash_header() has exclude_options parameter to optionally exclude TCP header from hash calculation, as described in RFC5925 (9.1), this is needed for interaction with middleboxes that may change "some TCP options". This is wired up to AO key flags and setsockopt() later. Similarly to TCP-MD5 hash TCP segment fragments. From this moment a user can start sending TCP-AO signed segments with one of crypto ahash algorithms from supported by Linux kernel. It can have a user-specified MAC length, to either save TCP option header space or provide higher protection using a longer signature. The inbound segments are not yet verified, TCP-AO option is ignored and they are accepted.

2023-10-27net/tcp: Prevent TCP-MD5 with TCP-AO being setDmitry Safonov2-2/+54
Be as conservative as possible: if there is TCP-MD5 key for a given peer regardless of L3 interface - don't allow setting TCP-AO key for the same peer. According to RFC5925, TCP-AO is supposed to replace TCP-MD5 and there can't be any switch between both on any connected tuple. Later it can be relaxed, if there's a use, but in the beginning restrict any intersection. Note: it's still should be possible to set both TCP-MD5 and TCP-AO keys on a listening socket for *different* peers.

2023-10-27net/tcp: Introduce TCP_AO setsockopt()sDmitry Safonov4-1/+88
Add 3 setsockopt()s: 1. TCP_AO_ADD_KEY to add a new Master Key Tuple (MKT) on a socket 2. TCP_AO_DEL_KEY to delete present MKT from a socket 3. TCP_AO_INFO to change flags, Current_key/RNext_key on a TCP-AO sk Userspace has to introduce keys on every socket it wants to use TCP-AO option on, similarly to TCP_MD5SIG/TCP_MD5SIG_EXT. RFC5925 prohibits definition of MKTs that would match the same peer, so do sanity checks on the data provided by userspace. Be as conservative as possible, including refusal of defining MKT on an established connection with no AO, removing the key in-use and etc. (1) and (2) are to be used by userspace key manager to add/remove keys. (3) main purpose is to set RNext_key, which (as prescribed by RFC5925) is the KeyID that will be requested in TCP-AO header from the peer to sign their segments with. At this moment the life of ao_info ends in tcp_v4_destroy_sock().

2023-10-27net/tcp: Prepare tcp_md5sig_pool for TCP-AODmitry Safonov1-14/+36
TCP-AO, similarly to TCP-MD5, needs to allocate tfms on a slow-path, which is setsockopt() and use crypto ahash requests on fast paths, which are RX/TX softirqs. Also, it needs a temporary/scratch buffer for preparing the hash. Rework tcp_md5sig_pool in order to support other hashing algorithms than MD5. It will make it possible to share pre-allocated crypto_ahash descriptors and scratch area between all TCP hash users. Internally tcp_sigpool calls crypto_clone_ahash() API over pre-allocated crypto ahash tfm. Kudos to Herbert, who provided this new crypto API. I was a little concerned over GFP_ATOMIC allocations of ahash and crypto_request in RX/TX (see tcp_sigpool_start()), so I benchmarked both "backends" with different algorithms, using patched version of iperf3[2]. On my laptop with i7-7600U @ 2.80GHz: clone-tfm per-CPU-requests TCP-MD5 2.25 Gbits/sec 2.30 Gbits/sec TCP-AO(hmac(sha1)) 2.53 Gbits/sec 2.54 Gbits/sec TCP-AO(hmac(sha512)) 1.67 Gbits/sec 1.64 Gbits/sec TCP-AO(hmac(sha384)) 1.77 Gbits/sec 1.80 Gbits/sec TCP-AO(hmac(sha224)) 1.29 Gbits/sec 1.30 Gbits/sec TCP-AO(hmac(sha3-512)) 481 Mbits/sec 480 Mbits/sec TCP-AO(hmac(md5)) 2.07 Gbits/sec 2.12 Gbits/sec TCP-AO(hmac(rmd160)) 1.01 Gbits/sec 995 Mbits/sec TCP-AO(cmac(aes128)) [not supporetd yet] 2.11 Gbits/sec So, it seems that my concerns don't have strong grounds and per-CPU crypto_request allocation can be dropped/removed from tcp_sigpool once ciphers get crypto_clone_ahash() support.

2023-10-27scsi: sd: Introduce manage_shutdown device flagDamien Le Moal1-2/+18
Commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop") change setting the manage_system_start_stop flag to false for libata managed disks to enable libata internal management of disk suspend/resume. However, a side effect of this change is that on system shutdown, disks are no longer being stopped (set to standby mode with the heads unloaded). While this is not a critical issue, this unclean shutdown is not recommended and shows up with increased smart counters (e.g. the unexpected power loss counter "Unexpect_Power_Loss_Ct"). Instead of defining a shutdown driver method for all ATA adapter drivers (not all of them define that operation), this patch resolves this issue by further refining the sd driver start/stop control of disks using the new flag manage_shutdown. If this new flag is set to true by a low level driver, the function sd_shutdown() will issue a START STOP UNIT command with the start argument set to 0 when a disk needs to be powered off (suspended) on system power off, that is, when system_state is equal to SYSTEM_POWER_OFF.

2023-10-26landlock: Support network rules with TCP bind and connectKonstantin Meskhidze1-0/+55
Add network rules support in the ruleset management helpers and the landlock_create_ruleset() syscall. Extend user space API to support network actions: * Add new network access rights: LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. * Add a new network rule type: LANDLOCK_RULE_NET_PORT tied to struct landlock_net_port_attr. The allowed_access field contains the network access rights, and the port field contains the port value according to the controlled protocol. This field can take up to a 64-bit value but the maximum value depends on the related protocol (e.g. 16-bit value for TCP). Network port is in host endianness [1]. * Add a new handled_access_net field to struct landlock_ruleset_attr that contains network access rights. * Increment the Landlock ABI version to 4. Implement socket_bind() and socket_connect() LSM hooks, which enable to control TCP socket binding and connection to specific ports. Expand access_masks_t from u16 to u32 to be able to store network access rights alongside filesystem access rights for rulesets' handled access rights. Access rights are not tied to socket file descriptors but checked at bind() or connect() call time against the caller's Landlock domain. For the filesystem, a file descriptor is a direct access to a file/data. However, for network sockets, we cannot identify for which data or peer a newly created socket will give access to. Indeed, we need to wait for a connect or bind request to identify the use case for this socket. Likewise a directory file descriptor may enable to open another file (i.e. a new data item), but this opening is also restricted by the caller's domain, not the file descriptor's access rights [2].

2023-10-26drm/sched: Convert the GPU scheduler to variable number of run-queuesLuben Tuikov1-3/+6
The GPU scheduler has now a variable number of run-queues, which are set up at drm_sched_init() time. This way, each driver announces how many run-queues it requires (supports) per each GPU scheduler it creates. Note, that run-queues correspond to scheduler "priorities", thus if the number of run-queues is set to 1 at drm_sched_init(), then that scheduler supports a single run-queue, i.e. single "priority". If a driver further sets a single entity per run-queue, then this creates a 1-to-1 correspondence between a scheduler and a scheduled entity.

The existing code checks for the correct state transition after sending a command. However, it is possible for the message box to return -1, which indicates an error, if an error has occurred in the firmware. We can detect if the error has occurred, and return a different error. In addition, there is no recovering from a CSPL error, so the retry mechanism is not needed in this case, and we can return immediately.

Adding it to readable registers means it will be correctly treated as volatile, and thus will not be cached.

2023-10-26iommu/vt-d: Disallow read-only mappings to nest parent domainLu Baolu1-1/+11
When remapping hardware is configured by system software in scalable mode as Nested (PGTT=011b) and with PWSNP field Set in the PASID-table-entry, it may Set Accessed bit and Dirty bit (and Extended Access bit if enabled) in first-stage page-table entries even when second-stage mappings indicate that corresponding first-stage page-table is Read-Only. As the result, contents of pages designated by VMM as Read-Only can be modified by IOMMU via PML5E (PML4E for 4-level tables) access as part of address translation process due to DMAs issued by Guest. This disallows read-only mappings in the domain that is supposed to be used as nested parent. Reference from Sapphire Rapids Specification Update [1], errata details, SPR17. Userspace should know this limitation by checking the IOMMU_HW_INFO_VTD_ERRATA_772415_SPR17 flag reported in the IOMMU_GET_HW_INFO ioctl.

2023-10-26iommufd: Add a nested HW pagetable objectNicolin Chen1-2/+29
IOMMU_HWPT_ALLOC already supports iommu_domain allocation for usersapce. But it can only allocate a hw_pagetable that associates to a given IOAS, i.e. only a kernel-managed hw_pagetable of IOMMUFD_OBJ_HWPT_PAGING type. IOMMU drivers can now support user-managed hw_pagetables, for two-stage translation use cases that require user data input from the user space. Add a new IOMMUFD_OBJ_HWPT_NESTED type with its abort/destroy(). Pair it with a new iommufd_hwpt_nested structure and its to_hwpt_nested() helper. Update the to_hwpt_paging() helper, so a NESTED-type hw_pagetable can be handled in the callers, for example iommufd_hw_pagetable_enforce_rr(). Screen the inputs including the parent PAGING-type hw_pagetable that has a need of a new nest_parent flag in the iommufd_hwpt_paging structure. Extend the IOMMU_HWPT_ALLOC ioctl to accept an IOMMU driver specific data input which is tagged by the enum iommu_hwpt_data_type. Also, update the @pt_id to accept hwpt_id too besides an ioas_id. Then, use them to allocate a hw_pagetable of IOMMUFD_OBJ_HWPT_NESTED type using the iommufd_hw_pagetable_alloc_nested() allocator.
