x86/resctrl: Allow different CODE/DATA configurations to be staged
Before the CDP resources can be merged, struct rdt_domain will need an array of struct resctrl_staged_config, one per type of configuration. Use the type as an index to the array to ensure that a schema configuration string can't specify the same domain twice. This will allow two schemata to apply configuration changes to one resource.

x86/resctrl: Group staged configuration into a separate struct
When configuration changes are made, the new value is written to struct rdt_domain's new_ctrl field and the have_new_ctrl flag is set. Later new_ctrl is copied to hardware by a call to update_domains(). Once the CDP resources are merged, there will be one new_ctrl field in use by two struct resctrl_schema requiring a per-schema IPI to copy the value to hardware. Move new_ctrl and have_new_ctrl into a new struct resctrl_staged_config. Before the CDP resources can be merged, struct rdt_domain will need an array of these, one per type of configuration. Using the type as an index to the array will ensure that a schema configuration string can't specify the same domain twice.

x86/resctrl: Move the schemata names into struct resctrl_schema
resctrl 'info' directories and schema parsing use the schema name. This lives in the struct rdt_resource, and is specified by the architecture code. Once the CDP resources are merged, there will only be one resource (and one name) in use by two schemata. To allow the CDP CODE/DATA property to be the type of configuration the schema uses, the name should also be per-schema. Add a name field to struct resctrl_schema, and use this wherever the schema name is exposed (or read from) user-space. Calculating max_name_width for padding the schemata file also moves as this is visible to user-space. As the names in struct rdt_resource already include the CDP information, schemata_list_create() copies them. schemata_list_create() includes the length of the CDP suffix when calculating max_name_width in preparation for CDP resources being merged.

x86/resctrl: Add a helper to read/set the CDP configuration
Whether CDP is enabled for a hardware resource like the L3 cache can be found by inspecting the alloc_enabled flags of the L3CODE/L3DATA struct rdt_hw_resources, even if they aren't in use. Once these resources are merged, the flags can't be compared. Whether CDP is enabled needs tracking explicitly. If another architecture is emulating CDP the behaviour may not be per-resource. 'cdp_capable' needs to be visible to resctrl, even if its not in use, as this affects the padding of the schemata table visible to user-space. Add cdp_enabled to struct rdt_hw_resource and cdp_capable to struct rdt_resource. Add resctrl_arch_set_cdp_enabled() to let resctrl enable or disable CDP on a resource. resctrl_arch_get_cdp_enabled() lets it read the current state.

x86/resctrl: Pass the schema to resctrl filesystem functions
Once the CDP resources are merged, there will be two struct resctrl_schema for one struct rdt_resource. CDP becomes a type of configuration that belongs to the schema. Helpers like rdtgroup_cbm_overlaps() need access to the schema to query the configuration (or configurations) based on schema properties. Change these functions to take a struct schema instead of the struct rdt_resource. All the modified functions are part of the filesystem code that will move to /fs/resctrl once it is possible to support a second architecture.

x86/resctrl: Add resctrl_arch_get_num_closid()
To initialise struct resctrl_schema's num_closid, schemata_list_create() reaches into the architectures private structure to retrieve num_closid from the struct rdt_hw_resource. The 'half the closids' behaviour should be part of the filesystem parts of resctrl that are the same on any architecture. struct resctrl_schema's num_closid should include any correction for CDP. Having two properties called num_closid is likely to be confusing when they have different values. Add a helper to read the resource's num_closid from the arch code. This should return the number of closid that the resource supports, regardless of whether CDP is in use. Once the CDP resources are merged, schemata_list_create() can apply the correction itself. Using a type with an obvious size for the arch helper means changing the type of num_closid to u32, which matches the type already used by struct rdtgroup. reset_all_ctrls() does not use resctrl_arch_get_num_closid(), even though it sets up a structure for modifying the hardware. This function will be part of the architecture code, the maximum closid should be the maximum value the hardware has, regardless of the way resctrl is using it. All the uses of num_closid in core.c are naturally part of the architecture specific code.

x86/resctrl: Store the effective num_closid in the schema
Struct resctrl_schema holds properties that vary with the style of configuration that resctrl applies to a resource. There are already two values for the hardware's num_closid, depending on whether the architecture presents the L3 or L3CODE/L3DATA resources. As the way CDP changes the number of control groups that resctrl can create is part of the user-space interface, it should be managed by the filesystem parts of resctrl. This allows the architecture code to only describe the value the hardware supports. Add num_closid to resctrl_schema. This is the value seen by the filesystem, which may be different to the maximum value described by the arch code when CDP is enabled. These functions operate on the num_closid value that is exposed to user-space: * rdtgroup_parse_resource() * rdtgroup_schemata_show() * rdt_num_closids_show() * closid_init() Change them to use the schema value instead. schemata_list_create() sets this value, and reaches into the architecture-specific structure to get the value. This will eventually be replaced with a helper.

x86/resctrl: Label the resources with their configuration type
The names of resources are used for the schema name presented to user-space. The name used is rooted in a structure provided by the architecture code because the names are different when CDP is enabled. x86 implements this by swapping between two sets of resource structures based on their alloc_enabled flag. The type of configuration in-use is encoded in the name (and cbm_idx_offset). Once the CDP behaviour is moved into the parts of resctrl that will move to /fs/, there will be two struct resctrl_schema for one struct rdt_resource. The schema describes the type of configuration being applied to the resource. The name of the schema should be generated by resctrl, base on the type of configuration. To do this struct resctrl_schema needs to store the type of configuration in use for a schema. Create an enum resctrl_conf_type describing the options, and add it to struct resctrl_schema. The underlying resources are still separate, as cbm_idx_offset is still in use. Temporarily label all the entries in rdt_resources_all[] and copy that value to struct resctrl_schema. Copying the value ensures there is no mismatch while the filesystem parts of resctrl are modified to use the schema. Once the resources are merged, the filesystem code can assign this value based on the schema being created.

x86/resctrl: Add a separate schema list for resctrl
Resctrl exposes schemata to user-space, which allow the control values
to be specified for a group of tasks.
User-visible properties of the interface, (such as the schemata names
and how the values are parsed) are rooted in a struct provided by the
architecture code. (struct rdt_hw_resource). Once a second architecture
uses resctrl, this would allow user-visible properties to diverge
between architectures.
These properties should come from the resctrl code that will be common
to all architectures. Resctrl has no per-schema structure, only struct
rdt_{hw_,}resource. Create a struct resctrl_schema to hold the
rdt_resource. Before a second architecture can be supported, this
structure will also need to hold the schema name visible to user-space
and the type of configuration values for resctrl.

x86/resctrl: Split struct rdt_domain
resctrl is the defacto Linux ABI for SoC resource partitioning features. To support it on another architecture, it needs to be abstracted from the features provided by Intel RDT and AMD PQoS, and moved to /fs/. struct rdt_domain contains a mix of architecture private details and properties of the filesystem interface user-space uses. Continue by splitting struct rdt_domain, into an architecture private 'hw' struct, which contains the common resctrl structure that would be used by any architecture. The hardware values in ctrl_val and mbps_val need to be accessed via helpers to allow another architecture to convert these into a different format if necessary. After this split, filesystem code paths touching a 'hw' struct indicates where an abstraction is needed. Splitting this structure only moves types around, and should not lead to any change in behaviour.

To support it on another architecture, it needs to be abstracted from the features provided by Intel RDT and AMD PQoS, and moved to /fs/. struct rdt_resource contains a mix of architecture private details and properties of the filesystem interface user-space uses. Start by splitting struct rdt_resource, into an architecture private 'hw' struct, which contains the common resctrl structure that would be used by any architecture. The foreach helpers are most commonly used by the filesystem code, and should return the common resctrl structure. for_each_rdt_resource() is changed to walk the common structure in its parent arch private structure. Move as much of the structure as possible into the common structure in the core code's header file. The x86 hardware accessors remain part of the architecture private code, as do num_closid, mon_scale and mbm_width. mon_scale and mbm_width are used to detect overflow of the hardware counters, and convert them from their native size to bytes. Any cross-architecture abstraction should be in terms of bytes, making these properties private. The hardware's num_closid is kept in the private structure to force the filesystem code to use a helper to access it. MPAM would return a single value for the system, regardless of the resource. Using the helper prevents this field from being confused with the version of num_closid that is being exposed to user-space (added in a later patch). After this split, filesystem code touching a 'hw' struct indicates where an abstraction is needed. Splitting this structure only moves types around, and should not lead to any change in behaviour.

From Pavel Skripkin. 2) Revert "xfrm: policy: Read seqcount outside of rcu-read side in xfrm_policy_lookup_bytype". This commit tried to fix a lockin bug, but only cured some of the symptoms. A proper fix is applied on top of this revert. 3) Fix a locking bug on xfrm state hash resize. A recent change on sequence counters accidentally repaced a spinlock by a mutex. Fix from Frederic Weisbecker. 4) Fix possible user-memory-access in xfrm_user_rcv_msg_compat(). From Dmitry Safonov. 5) Add initialiation sefltest fot xfrm_spdattr_type_t.

bpf: Fix leakage due to insufficient speculative store bypass mitigation
Spectre v4 gadgets make use of memory disambiguation, which is a set of techniques that execute memory access instructions, that is, loads and stores, out of program order; Intel's optimization manual, section 2.4.4.5: A load instruction micro-op may depend on a preceding store. Many microarchitectures block loads until all preceding store addresses are known. The memory disambiguator predicts which loads will not depend on any previous stores. When the disambiguator predicts that a load does not have such a dependency, the load takes its data from the L1 data cache. Eventually, the prediction is verified. If an actual conflict is detected, the load and all succeeding instructions are re-executed. |

bpf: Introduce BPF nospec instruction for mitigating Spectre v4
In case of JITs, each of the JIT backends compiles the BPF nospec instruction /either/ to a machine instruction which emits a speculation barrier /or/ to /no/ machine instruction in case the underlying architecture is not affected by Speculative Store Bypass or has different mitigations in place already. This covers both x86 and (implicitly) arm64: In case of x86, we use 'lfence' instruction for mitigation. In case of arm64, we rely on the firmware mitigation as controlled via the ssbd kernel parameter. Whenever the mitigation is enabled, it works for all of the kernel code with no need to provide any additional instructions here (hence only comment in arm64 JIT). Other archs can follow as needed. The BPF nospec instruction is specifically targeting Spectre v4 since i) we don't use a serialization barrier for the Spectre v1 case, and ii) mitigation instructions for v1 and v4 might be different on some archs. The BPF nospec is required for a future commit, where the BPF verifier does annotate intermediate BPF programs with speculation barriers.

bpf, sockmap: Fix memleak on ingress msg enqueue
If backlog handler is running during a tear down operation we may enqueue
data on the ingress msg queue while tear down is trying to free it.
sk_psock_backlog()
sk_psock_handle_skb()
skb_psock_skb_ingress()
sk_psock_skb_ingress_enqueue()
sk_psock_queue_msg(psock,msg)
spin_lock(ingress_lock)
sk_psock_zap_ingress()
_sk_psock_purge_ingerss_msg()
_sk_psock_purge_ingress_msg()
-- free ingress_msg list --
spin_unlock(ingress_lock)
spin_lock(ingress_lock)
list_add_tail(msg,ingress_msg) <- entry on list with no one
left to free it.
spin_unlock(ingress_lock)
To fix we only enqueue from backlog if the ENABLED bit is set. The tear
down logic clears the bit with ingress_lock set so we wont enqueue the
msg in the last step.

net: llc: fix skb_over_panic
Syzbot reported skb_over_panic() in llc_pdu_init_as_xid_cmd(). The
problem was in wrong LCC header manipulations.
Syzbot's reproducer tries to send XID packet. llc_ui_sendmsg() is
doing following steps:
1. skb allocation with size = len + header size
len is passed from userpace and header size
is 3 since addr->sllc_xid is set.
2. skb_reserve() for header_len = 3
3. filling all other space with memcpy_from_msg()
Ok, at this moment we have fully loaded skb, only headers needs to be
filled.
Then code comes to llc_sap_action_send_xid_c(). This function pushes 3
bytes for LLC PDU header and initializes it. Then comes
llc_pdu_init_as_xid_cmd(). It initalizes next 3 bytes *AFTER* LLC PDU
header and call skb_push(skb, 3). This looks wrong for 2 reasons:
1. Bytes rigth after LLC header are user data, so this function
was overwriting payload.
2. skb_push(skb, 3) call can cause skb_over_panic() since
all free space was filled in llc_ui_sendmsg(). (This can
happen is user passed 686 len: 686 + 14 (eth header) + 3 (LLC
header) = 703. SKB_DATA_ALIGN(703) = 704)
So, in this patch I added 2 new private constansts: LLC_PDU_TYPE_U_XID
and LLC_PDU_LEN_U_XID. LLC_PDU_LEN_U_XID is used to correctly reserve
header size to handle LLC + XID case. LLC_PDU_TYPE_U_XID is used by
llc_pdu_header_init() function to push 6 bytes instead of 3. And finally
I removed skb_push() call from llc_pdu_init_as_xid_cmd().
This changes should not affect other parts of LLC, since after
all steps we just transmit buffer.

sctp: send pmtu probe only if packet loss in Search Complete state
This patch is to introduce last_rtx_chunks into sctp_transport to detect
if there's any packet retransmission/loss happened by checking against
asoc's rtx_data_chunks in sctp_transport_pl_send().
If there is, namely, transport->last_rtx_chunks != asoc->rtx_data_chunks,
the pmtu probe will be sent out. Otherwise, increment the pl.raise_count
and return when it's in Search Complete state.
With this patch, if in Search Complete state, which is a long period, it
doesn't need to keep probing the current pmtu unless there's data packet
loss. This will save quite some traffic.
v1->v2:
- add the missing Fixes tag.

sctp: improve the code for pmtu probe send and recv update
This patch does 3 things:
- make sctp_transport_pl_send() and sctp_transport_pl_recv()
return bool type to decide if more probe is needed to send.
- pr_debug() only when probe is really needed to send.
- count pl.raise_count in sctp_transport_pl_send() instead of
sctp_transport_pl_recv(), and it's only incremented for the
1st probe for the same size.
These are preparations for the next patch to make probes happen
only when there's packet loss in Search Complete state.

mm: call flush_dcache_page() in memcpy_to_page() and memzero_page()
memcpy_to_page and memzero_page can write to arbitrary pages, which could be in the page cache or in high memory, so call flush_kernel_dcache_pages to flush the dcache. This is a problem when using these helpers on dcache challeneged architectures. Right now there are just a few users, chances are no one used the PC floppy driver, the aha1542 driver for an ISA SCSI HBA, and a few advanced and optional btrfs and ext4 features on those platforms yet since the conversion.

Pull arm64 fixes from Will Deacon:
"A pair of arm64 fixes for -rc3. The straightforward one is a fix to
our firmware calling stub, which accidentally started corrupting the
link register on machines with SVE. Since these machines don't really
exist yet, it wasn't spotted in -next.
The other fix is a revert-and-a-bit of a patch originally intended to
allow PTE-level huge mappings for the VMAP area on 32-bit PPC 8xx. A
side-effect of this change was that our pXd_set_huge() implementations
could be replaced with generic dummy functions depending on the levels
of page-table being used, which in turn broke the boot if we fail to
create the linear mapping as a result of using these functions to
operate on the pgd. Huge thanks to Michael Ellerman for modifying the
revert so as not to regress PPC 8xx in terms of functionality.
Anyway, that's the background and it's also available in the commit
message along with Link tags pointing at all of the fun.
