2021-04-14KEYS: trusted: Add generic trusted keys frameworkSumit Garg2-21/+61
Current trusted keys framework is tightly coupled to use TPM device as an underlying implementation which makes it difficult for implementations like Trusted Execution Environment (TEE) etc. to provide trusted keys support in case platform doesn't posses a TPM device. Add a generic trusted keys framework where underlying implementations can be easily plugged in. Create struct trusted_key_ops to achieve this, which contains necessary functions of a backend. Also, define a module parameter in order to select a particular trust source in case a platform support multiple trust sources. In case its not specified then implementation itetrates through trust sources list starting with TPM and assign the first trust source as a backend which has initiazed successfully during iteration. Note that current implementation only supports a single trust source at runtime which is either selectable at compile time or during boot via aforementioned module parameter.

2021-04-14security: keys: trusted: Make sealed key properly interoperableJames Bottomley1-0/+2
The current implementation appends a migratable flag to the end of a key, meaning the format isn't exactly interoperable because the using party needs to know to strip this extra byte. However, all other consumers of TPM sealed blobs expect the unseal to return exactly the key. Since TPM2 keys have a key property flag that corresponds to migratable, use that flag instead and make the actual key the only sealed quantity. This is secure because the key properties are bound to a hash in the private part, so if they're altered the key won't load. Backwards compatibility is implemented by detecting whether we're loading a new format key or not and correctly setting migratable from the last byte of old format keys.

2021-04-14security: keys: trusted: use ASN.1 TPM2 key format for the blobsJames Bottomley1-0/+1
Modify the TPM2 key format blob output to export and import in the ASN.1 form for TPM2 sealed object keys. For compatibility with prior trusted keys, the importer will also accept two TPM2B quantities representing the public and private parts of the key. However, the export via keyctl pipe will only output the ASN.1 format. The benefit of the ASN.1 format is that it's a standard and thus the exported key can be used by userspace tools (openssl_tpm2_engine, openconnect and tpm2-tss-engine). The format includes policy specifications, thus it gets us out of having to construct policy handles in userspace and the format includes the parent meaning you don't have to keep passing it in each time. This patch only implements basic handling for the ASN.1 format, so keys with passwords but no policy.

2021-04-14security: keys: trusted: fix TPM2 authorizationsJames Bottomley1-0/+1
In TPM 1.2 an authorization was a 20 byte number. The spec actually recommended you to hash variable length passwords and use the sha1 hash as the authorization. Because the spec doesn't require this hashing, the current authorization for trusted keys is a 40 digit hex number. For TPM 2.0 the spec allows the passing in of variable length passwords and passphrases directly, so we should allow that in trusted keys for ease of use. Update the 'blobauth' parameter to take this into account, so we can now use plain text passwords for the keys. so before keyctl add trusted kmk "new 32 blobauth=f572d396fae9206628714fb2ce00f72e94f2258fkeyhandle=81000001" @u after we will accept both the old hex sha1 form as well as a new directly supplied password: keyctl add trusted kmk "new 32 blobauth=hello keyhandle=81000001" @u Since a sha1 hex code must be exactly 40 bytes long and a direct password must be 20 or less, we use the length as the discriminator for which form is input. Note this is both and enhancement and a potential bug fix. The TPM 2.0 spec requires us to strip leading zeros, meaning empyty authorization is a zero length HMAC whereas we're currently passing in 20 bytes of zeros. A lot of TPMs simply accept this as OK, but the Microsoft TPM emulator rejects it with TPM_RC_BAD_AUTH, so this patch makes the Microsoft TPM emulator work with trusted keys.

2021-04-14oid_registry: Add TCG defined OIDS for TPM keysJames Bottomley1-0/+5
The TCG has defined an OID prefix "2.23.133.10.1" for the various TPM key uses. We've defined three of the available numbers: 2.23.133.10.1.3 TPM Loadable key. This is an asymmetric key (Usually RSA2048 or Elliptic Curve) which can be imported by a TPM2_Load() operation. 2.23.133.10.1.4 TPM Importable Key. This is an asymmetric key (Usually RSA2048 or Elliptic Curve) which can be imported by a TPM2_Import() operation. Both loadable and importable keys are specific to a given TPM, the difference is that a loadable key is wrapped with the symmetric secret, so must have been created by the TPM itself. An importable key is wrapped with a DH shared secret, and may be created without access to the TPM provided you know the public part of the parent key. 2.23.133.10.1.5 TPM Sealed Data. This is a set of data (up to 128 bytes) which is sealed by the TPM. It usually represents a symmetric key and must be unsealed before use. The ASN.1 binary key form starts of with this OID as the first element of a sequence, giving the binary form a unique recognizable identity marker regardless of encoding.

2021-04-14lib: Add ASN.1 encoderJames Bottomley1-0/+32
We have a need in the TPM2 trusted keys to return the ASN.1 form of the TPM key blob so it can be operated on by tools outside of the kernel. The specific tools are the openssl_tpm2_engine, openconnect and the Intel tpm2-tss-engine. To do that, we have to be able to read and write the same binary key format the tools use. The current ASN.1 decoder does fine for reading, but we need pieces of an ASN.1 encoder to write the key blob in binary compatible form. For backwards compatibility, the trusted key reader code will still accept the two TPM2B quantities that it uses today, but the writer will only output the ASN.1 form. The current implementation only encodes the ASN.1 bits we actually need.

2021-04-14of: net: pass the dst buffer to of_get_mac_address()Michael Walle2-4/+4
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

2021-04-13arm64: Introduce prctl(PR_PAC_{SET,GET}_ENABLED_KEYS)Peter Collingbourne2-0/+5
This change introduces a prctl that allows the user program to control which PAC keys are enabled in a particular task. The main reason why this is useful is to enable a userspace ABI that uses PAC to sign and authenticate function pointers and other pointers exposed outside of the function, while still allowing binaries conforming to the ABI to interoperate with legacy binaries that do not sign or authenticate pointers. The idea is that a dynamic loader or early startup code would issue this prctl very early after establishing that a process may load legacy binaries, but before executing any PAC instructions. This change adds a small amount of overhead to kernel entry and exit due to additional required instruction sequences. On a DragonBoard 845c (Cortex-A75) with the powersave governor, the overhead of similar instruction sequences was measured as 4.9ns when simulating the common case where IA is left enabled, or 43.7ns when simulating the uncommon case where IA is disabled. These numbers can be seen as the worst case scenario, since in more realistic scenarios a better performing governor would be used and a newer chip would be used that would support PAC unlike Cortex-A75 and would be expected to be faster than Cortex-A75. On an Apple M1 under a hypervisor, the overhead of the entry/exit instruction sequences introduced by this patch was measured as 0.3ns in the case where IA is left enabled, and 33.0ns in the case where IA is disabled.

2021-04-13ASoC: simple-card-utils: remove asoc_simple_parse_xxx()Kuninori Morimoto1-11/+0
ASoC is now supporting multi DAI, but, current simple-card / audio-graph are assuming fixed single DAI. Now, asoc_simple_parse_xxx() macro is assuming single DAI. To support multi-CPU/Codec, this patch unpack asoc_simple_parse_xxx() macro, and uses "&dai_link->cpus[i]" instead of "dai_link->cpus".

2021-04-13ASoC: simple-card-utils: remove li->dais/li->confKuninori Morimoto1-2/+0
li->dais is same as number of CPU + Codec, li->conf is same as number of Codec when dummy-Codec. li->dais/li->conf are no longer needed. This patch removes these.

2021-04-13netfilter: conntrack: convert sysctls to u8Florian Westphal1-13/+10
log_invalid sysctl allows values of 0 to 255 inclusive so we no longer need a range check: the min/max values can be removed. This also removes all member variables that were moved to net_generic data in previous patches. This reduces size of netns_ct struct by one cache line.

2021-04-13netfilter: conntrack: move ct counter to net_generic dataFlorian Westphal1-0/+2
Its only needed from slowpath (sysctl, ctnetlink, gc worker) and when a new conntrack object is allocated. Furthermore, each write dirties the otherwise read-mostly pernet data in struct net.ct, which are accessed from packet path. Move it to the net_generic data. This makes struct netns_ct read-mostly.

2021-04-13netfilter: conntrack: move expect counter to net_generic dataFlorian Westphal1-0/+1
Creation of a new conntrack entry isn't a frequent operation (compared to 'ct entry already exists'). Creation of a new entry that is also an expected (related) connection even less so. Place this counter in net_generic data. A followup patch will also move the conntrack count -- this will make netns_ct a read-mostly structure.
