commit 4bd608048e6fa77d3154b8d90b85fc2b66c6bf1a
Author: Christophe Milard <christophe.milard(a)linaro.org>
Date: Thu Nov 3 14:24:49 2016 +0100
linux-gen: _ishmphy: adding function for physical address query
The function _odp_ishmphy_getphy() is added to query for physical
addresses (given a virtual address)
This function is meant to be used to populate the physical address
of packet segments which are to be used by drivers (without iommu).
The function _odp_ishmphy_can_getphy(), also added, return true if
_odp_ishmphy_getphy() is able to works (as it requires specific
permission)

drv_pci.c: scan devices on demand
Only the devices required by PacketIO open are scanned and added to the
list of known devices.
The pci interface now adds a function to open the device on-demand.
The pci_dump_all() function has been updated to report the current
kernel driver and BARs.

linux-gen: pool: add inlined accessors for selected pool parameters
Add inlined accessors for pool_t members pool_hdl and uarea_size. This
enables removing the matching members from odp_buffer_hdr_t, and thus
reduces per buffer overhead.

linux-gen: crypto: set packet error flag depending on crypto result operation
To speed up fast path of crypto packet operations, set error flag
depending on the crypto result operation. This allows applications to
fast-forward packets w/o errors and inspect crypto result only for
erroneous packets.

Add new ipsec_err error flag, which is set by IPsec code if there was an
error during IPsec packet processing. This allow application code to
quickly check packets using odp_packet_has_error() function and use fast
path if there was none.

linux-gen: ipsec: fix soft/hard limits check
Split count expiration check into two phases:
- optional precheck, run before crypto, which fails only if hard limit
is already breached
- update, run after crypto in INBOUND case, so that limits will not be
updated for packets failing ICV check.

+== IPsec services
+
+In addition to general cryptographic services, ODP offers offload support for
+the IPsec protocol. IPsec is a general term referencing a suite of protocols
+and packet formats and as such a full discussion of IPsec is beyond the scope
+of this document. See https://tools.ietf.org/html/rfc4301[RFC 4301] and
+related RFCs for more detail. This section assumes the reader is already
+familiar with IPsec and focuses on explaining the ODP APIs that support it.
+
+ODP provides APIs for the following IPsec services:
+
+* General IPsec configuration
+* Security Association (SA) configuration and lifecycle management
+* Synchronous and Asynchronous IPsec lookaside processing
+* Inline processing for full IPsec RX and/or TX offload
+* Pipelining for RX traffic
+* Fragmentation support for TX traffic
+* IPsec event management
+
+=== IPsec Capabilities and Configuration
+As with other features, ODP provides APIs that permit applications to query
+platform-specific IPsec capabilities. The `odp_ipsec_capability()` API queries
+the general IPsec features available while the `odp_ipsec_cipher_capability()`
+and `odp_ipsec_auth_capability()` APIs provide detail on the range of
+cipher and authentication algorithms supported by IPsec on this platform.
+
+General IPsec capabilities that are reported include:
+
+* The IPsec operation modes supported by this implementation. Different
+operation modes may be _not supported_, _supported_, or _preferred_. A
+preferred form means that this mode takes advantage of hardware
+acceleration features to achieve best performance.
+* Whether IPsec AH processing is supported. All ODP platforms must provide
+support for IPsec ESP processing, however since AH is relatively rare, it
+may not be supported, or supported only via software emulation (_e.g.,_ be
+non-preferred).
+* Whether IPsec headers can be retained on decrypt for inbound inline
+operations.
+* Whether classification pipelining is supported (to be discussed below).
+
+In addition, capabilities also inform the application of the maximum number
+of destination queues and classification CoS targets supported. These
+will be discussed further later.
+
+==== IPsec Operation Modes
+IPsec operates in one of three modes: Synchronous, Asynchronous, and Inline.
+
+==== Lookaside Processing
+Synchronous and Asynchronous are types of _lookaside_ processing. Which of
+these forms may be used depends on the IPsec operation mode. So synchronous
+APIs may only be used when operating in synchronous mode, and asynchronous
+APIs may only be used when operating in asynchronous mode.
+
+In lookaside mode, the application receives (or creates) an IPsec packet and
+then uses ODP to perform one of two functions:
+
+* To decrypt an IPsec packet into a "normal" packet
+* To take a "normal" packet and encrypt it into an IPsec packet.
+
+This process may be performed _synchronously_ with the APIs `odp_ipsec_in()`
+(to decrypt) and `odp_ipsec_out()` (to encrypt). Upon return from these calls
+the requested packet transformation is complete, or an error return code
+indicates that it could not be performed (_e.g.,_ packet decryption failed).
+
+Synchronous processing may be preferred if the application has a large number
+of worker threads so that blocking any individual worker while IPsec processing
+is performed represents a reasonable design. The alternative is to use
+_asynchronous_ forms of these APIs:
+
+* `odp_ipsec_in_enq()` for decrypt
+* `odp_ipsec_out_enq()` for encrypt
+
+These simply pass packets to IPsec for processing. When this processing is
+complete, the resulting packets are sent to the completion queue associated
+with the SA used by the operation, serving as IPsec completion events as
+shown here:
+
+image::ipsec-lookaside.svg[align="center"]
+
+If the operation fails because SA lookup failed for inbound processing, then
+these result packets are sent to the default queue specified as part of the
+`odp_ipsec_inbound_config_t` used in the `odp_ipsec_config()` call.
+
+Following an asynchronous IPsec call, the worker thread moves on to process
+other events until the IPsec completion shows up. At that point the worker
+thread sees whether the operation was successful or not and continues
+processing for that packet. These events may be direct-polled with
+`odp_queue_deq()` if the completion queue was created as a plain queue, or
+processed via the ODP scheduler if the completion queue was created as a
+scheduled queue.
+
+==== Inline Processing
+While lookaside processing offers flexibility, it still requires extra
+processing steps not required by modern hardware. To avoid this overhead
+ODP also offers _inline_ processing support for IPsec. In this mode the
+processing of IPsec packets on the RX and TX paths is fully offloaded as
+shown here:
+
+image::ipsec-inline.svg[align="center"]
+
+It is worth noting that, depending on the implementation and application
+needs, inline processing may be enabled only for one direction (inbound or
+outbound) or for both directions.
+
+On the receive side, once configured for inline processing, arriving IPsec
+packets that are recognized at the PktIO interface are decrypted automatically
+before the application ever sees them. On the transmit side, the application
+calls `odp_ipsec_out_inline()` and the packet is encrypted and queued for
+transmission as a single operation without further application involvement.
+Note that if an inbound IPsec packet is not recognized (_e.g.,_ it belongs to
+an unknown SA) then it will be presented to the application as-is without
+further processing. The application may then use a lookaside call to process
+the packet if it is able to supply a matching SA by other means.
+
+On the receive side, after an IPsec packet is decrypted, it may be
+_pipelined_ to the ODP classifier or added to a poll queue, as the
+application wishes. The advantage of classification pipelining is that inbound
+IPsec traffic is automatically decrypted and classified into appropriate
+flow-based queues for ease of processing.
+
+On the transmit side, since IPsec encryption and tunneling may exceed an
+output MTU, ODP also offers support for MTU configuration and automatic IPsec
+TX fragmentation.
+
+Both classification pipelining and TX fragmentation support are support
+features that are indicated by `odp_ipsec_capability()`.
+
+Note that at present inline IPsec output support sends resulting packets
+directly to an output PktIO. If it's desired to send them to the ODP
+Traffic Manager for shaping prior to transmission, use the lookaside APIs
+to perform the IPsec encrypt and then call `odp_tm_enq()` on the resulting
+packet.
+
+=== IPsec Configuration
+Prior to making use of IPsec services, the `odp_ipsec_config()` API is used to
+configure IPsec processing options. This API takes a pointer to an
+`odp_ipsec_config_t` struct as its argument.
+
+The `odp_ipsec_config_t` struct specifies the inbound and outbound processing
+modes (SYNC, ASYNC, or INLINE) that the application plans to use, the maximum
+number of Security Associations it will use, and sets inbound and outbound
+processing options.
+
+==== IPsec Inbound Configuration
+Inbound configuration options for IPsec specify the default `odp_queue_t` to
+be used for processing global events like SA lookup failures, how Security
+Parameter Index (SPI) lookup is to be performed, and whether the application
+requires ODP to retain outer headers for decrypted IPsec packets.
+
+Parsing options specify how "deep" decrypted packets are to be parsed
+after IPsec processing by specifying the packet layers of interest to the
+application (None, L2, L3, L4, or All). And which checksums should be verified
+on decrypted packets.
+
+==== IPsec Outbound Configuration
+Outbound configuration options for IPsec specify checksum insertion processing
+that should be performed prior to encryption.
+
+=== IPsec Events
+IPsec introduces one new event type and one new event subtype. These are:
+
+* IPsec packet events. These are events of type `ODP_EVENT_PACKET` that have
+subtype `ODP_EVENT_PACKET_IPSEC`. These are packets that carry additional
+IPsec-related metadata in the form of an `odp_ipsec_packet_result_t` struct
+that can be retrieved from the packet via the `odp_ipsec_result()` API.
+
+* IPsec status notifications. These are events of type `ODP_EVENT_IPSEC_STATUS`
+that indicate status events not associated with any particular IPsec
+packet. Such events carry status in the form of an `odp_ipsec_status_t`
+struct that is retrieved from the event via the `odp_ipsec_status()` API.
+
+IPsec-related events are thus part of normal and exception processing when
+working with IPsec.
+
+=== Security Associations (SAs)
+The fundamental "building block" for IPsec processing is the _Security
+Association (SA)_. Similar to a crypto session, the SA encapsulates the keying
+material and context needed to perform IPsec protocol processing for inbound
+or outbound packets on a given flow, as well as additional processing options
+that control how IPsec is to be used for packets processed under this
+SA. Security Associations are unidirectional (RX or TX) so a flow that
+requires both inbound (decrypt) and outbound (encrypt) IPsec functions will
+have two SAs associated with it. SAs in ODP are represented by the
+abstract type `odp_ipsec_sa_t`.
+
+After ODP initialization, IPsec support is dormant until it is configured
+by a call to `odp_ipsec_config()` as described earlier. Once configured,
+SAs may be created by calling `odp_ipsec_sa_create()`.
+
+==== SA Creation and Configuration
+The `odp_ipsec_sa_create()` API takes an `odp_ipsec_sa_param_t` argument that
+describes the SA to be created. Use the `odp_ipsec_sa_param_init()` API to
+initialize this to its default state and then override selected fields within
+the param struct as needed.
+
+Items specified in the `odp_ipsec_sa_param_t` struct include:
+
+* The direction of the SA (inbound or outbound).
+
+* The IPsec protocol being used (ESP or AH).
+
+* The IPsec protocol mode (Transport or Tunnel).
+
+* The parameters needed for the crypto and authentication algorithms to be
+used by this SA.
+
+* Miscellaneous SA options that control behavior such as use of Extended
+Sequence Numbers (ESNs), the use of UDP encapsulation, various copy
+options for header fields, and whether the TTL (Hop Limit) field should be
+decremented when operating in tunnel mode.
+
+* Parameters controlling the SA lifetime.
+
+* The Security Parameter Index (SPI) that packets will use to indicate that
+they belong to this SA.
+
+* The pipeline mode used by this SA.
+
+* The destination `odp_queue_t` to be used for events associated with this SA.
+
+* The user context pointer (and length) associated with this SA for
+application use.
+
+In addition, there are specific direction-specific parameters that vary
+based on whether the SA is for inbound or outbound use. For inbound SAs:
+
+* Controls for how this SA is to be looked up.
+
+* The minimum size of the anti-replay window to be used.
+
+* The default CoS to use when classification pipelining packets matching this
+SA.
+
+For outbound SAs:
+
+* Tunnel parameters to use when doing outbound processing in tunnel mode.
+
+* The fragmentation mode to be used.
+
+* The MTU to be used to control the maximum length IP packets that outbound
+IPsec operations may produce. This can be changed dynamically by the
+`odp_ipsec_sa_mtu_update()` API.
+
+As can be seen, SAs have a large degree of configurability.
+
+==== SA Lifecycle Management
+In discussing the lifecycle of an SA, it is useful to refer to the following
+state diagram:
+
+image::ipsec_fsm.svg[align="center"]
+
+After creation, IPsec services are active for this Security Association. The
+specific APIs that can be used on this SA depends on the IPsec operating mode
+that has been configured.
+
+===== IPsec Lookaside Processing
+If IPsec is operating in lookaside mode for the SA's direction (the
+`odp_ipsec_op_mode_t` is `ODP_IPSEC_OP_MODE_SYNC` or `ODP_IPSEC_OP_MODE_ASYNC`),
+then inbound or outbound lookaside operations may be performed. Asynchronous
+lookaside operations are also permitted if the SA is operating in inline
+mode, as described in the next section.
+
+The synchronous forms of these APIs are:
+
+* `odp_ipsec_in()`
+* `odp_ipsec_out()`
+
+Upon return from these calls, the return code tells the application the number
+of number of input packets that were consumed by the operation. The result of
+the operation is determined by calling the `odp_ipsec_result()` API for each
+output packet to retrieve its associated `odp_ipsec_result_t`.
+
+The asynchronous forms of these APIs are:
+
+* `odp_ipsec_in_enq()`
+* `odp_ipsec_out_enq()`
+
+Here again, the return code indicates how many input packets were
+processed. The success or failure is determined by inspecting the
+`odp_ipsec_result_t` associated with each packet completion event. These are
+presented as events of type `ODP_EVENT_PACKET` with subtype
+`ODP_EVENT_PACKET_IPSEC`.
+
+For both synchronous and asynchronous IPsec operations an input packet array
+is transformed into an output packet array as specified by a controlling
+parameter struct. For inbound operations, the `odp_ipsec_in_param_t` is
+used to specify how SA processing is to be performed for the requested
+operation. The caller may say that SA lookup processing should be performed
+for each input packet, a single (specified) SA should be used for all packets,
+or that each packet has a specified individual SA.
+
+For outbound lookaside operations, a corresponding `odp_ipsec_out_param_t`
+serves a similar role, but here the SA must be specified since the input
+packet(s) are non-IPsec packets. Again the option is to use a single SA for
+all input packets or one per input packet.
+
+For outbound operations, an associated array of `odp_ipsec_out_opt_t` structs
+is also used to control the fragmentation mode to be used as part of the
+outbound processing. Options here are to not fragment, to fragment before
+IPsec processing, after IPsec processing, or to only check whether IP
+fragmentation is needed but not to perform it. For check processing, the `mtu`
+status error bit in the `odp_ipsec_packet_result_t` is set if check processing
+detects that the resulting packet will not fit into the configured MTU. Note
+that the MTU associated with a given SA is set at SA creation and can be
+changed at any time via the `odp_ipsec_sa_mtu_update()` API.
+
+Once an asynchronous lookaside operation has been initiated, the worker thread
+that issued the asynchronous call can handle other events while waiting for
+the operation to complete. Completion of an asynchronous operation is
+indicated by the worker receiving an `ODP_EVENT_PACKET` that has subtype
+`ODP_EVENT_PACKET_IPSEC`. These events can be retrieved directly by polling
+the completion queue associated with the SA, or (more typically) via the ODP
+scheduler. Typical code for such completion processing would look as follows:
+
+[source,c]
+-----
+while (1) {
+ ev = odp_schedule(&queue, ODP_SCHED_WAIT);
+ ev_type = odp_event_types(ev, &ev_subtype);
+
+ switch (ev_type) {
+ case ODP_EVENT_PACKET:
+
+ switch (ev_subtype) {
+ case ODP_EVENT_PACKET_IPSEC:
+ pkt = odp_packet_from_event(ev);
+
+ if (odp_unlikely(odp_ipsec_result(&result, pkt) != 0)) {
+ /* Stale event, discard */
+ odp_event_free(ev);
+ continue;
+ }
+
+ if (odp_unlikely(result.status.all != ODP_IPSEC_OK)) {
+ if (result.status.error != ODP_IPSEC_OK) {
+ ...process error result
+ odp_event_free(ev);
+ continue;
+ } else {
+ ...process packet warnings
+ }
+ }
+
+ my_context = odp_ipsec_sa_context(result.sa);
+
+ if (result.flag.inline_mode) {
+ ...process inline inbound packet
+ } else {
+ ...process the async completion event
+ }
+
+ ...
+ break;
+
+ case ...
+ }
+ break;
+
+ case ODP_EVENT_IPSEC_STATUS:
+ ...process IPsec status event
+ break;
+
+ }
+}
+-----
+
+===== IPsec Inline Processing
+When IPsec is configured to operate in `ODP_IPSEC_OP_MODE_INLINE` mode,
+inbound processing is implicit. The application never sees these packets until
+after IPsec has already decrypted them. As shown in the code sketch above,
+such packets appear as events of subtype `ODP_EVENT_PACKET_IPSEC` and the
+`flag` field in the associated `odp_ipsec_packet_result_t` indicates
+`inline_mode`.
+
+For outbound IPsec processing, the `odp_ipsec_out_inline()` API operates as
+a "fire and forget" API. A success return code from this call indicates that
+the packet will be encrypted and transmitted to the `odp_pktio_t` indicated
+in the `odp_ipsec_out_inline_param_t` specified at the time of the call without
+any further application involvement. Only if a problem arises will the packet
+be returned to the application with an `odp_ipsec_packet_result_t` indicating
+the nature of the problem.
+
+Note that while operating in inline mode, asychronous lookaside operations are
+also permitted. This provide the application with additional flexibility if,
+for example, some packets need additional handling that cannot be supported
+directly with inline IPsec processing.
+
+==== SA Lifetimes
+A fundamental principle of good security is that the keying material
+associated with sessions has a limited lifetime. In effect, keys grow "stale"
+over time or due to being used to encrypt too much data. The metrics used
+to limit effective SA lifetimes are:
+
+* Duration (time)
+* Usage (volume of traffic using the keys)
+
+Associated with each of these metrics are "soft" and "hard" limits. When a
+hard limit is reached, the SA is expired and cannot be used further. To support
+graceful transition to a replacement SA, soft limits are used. A soft limit is
+similar to a "low fuel" warning light on a car. It alerts the application that
+the SA is nearing the end of its useful life and should be renegotiated even
+as the SA continues to work normally.
+
+ODP support for SA limits is based on packet/byte counts. Applications that
+wish to use time-based SA limits may do so on their own using the timing
+facilities that ODP provides. However, since especially with inline IPsec
+processing, the application may not have explicit knowledge of the traffic
+volumes associated with a given SA, support for usage-based limits is
+integrated into ODP IPsec support.
+
+At `odp_ipsec_sa_create()` time, one of the fields in the
+`odp_ipsec_sa_param_t` struct is the `odp_ipsec_lifetime_t` sub-structure.
+This struct allows hard and/or soft limits to be specified in terms of total
+bytes encrypted/decrypted, total packet count, or both. A limit specification
+of 0 indicates no limit for that metric. If either is specified, the limit
+is triggered on whichever occurs first. Given the defined behavior of hard vs.
+soft limits, the soft limits, if used, should always be specified as lower
+than the hard limits. These should be sufficiently lower to enable adequate
+time to switch over to a replacement SA before the hard limit is reached.
+
+As noted, when an SA hard limit is reached the SA immediately enters the
+expired state and attempts to use it further are failed with an
+`odp_ipsec_result_t` that indicates a hard expiration limit. When a soft
+limit is reached for packets sent via `odp_ipsec_out_inline()`, this results
+in an `ODP_EVENT_IPSEC_STATUS` event being sent to the application on the
+queue associated with the SA that has reached the soft limit. This status
+event has an `odp_ipsec_status_id_t` of `ODP_IPSEC_STATUS_WARN` with a
+`odp_ipsec_warn_t` bits set to indicate the type of soft expiration reached.
+Receipt of this event alerts the application that the SA is nearing the end of
+its useful life and that it should be replaced. It is the application's
+responsibility to heed this warning. It is implementation-defined how many
+such warnings are issued when a soft limit is exceeded (once, first N packets,
+or all packets beyond the limit), so applications should be written to
+allow for possible repeated warnings.
+
+When operating in lookaside mode, expiration limits are carried as a warning
+in the `odp_op_status_t` section of the `odp_ipsec_result_t` struct. The same
+is true for inline inbound packets. When the soft limit is reached, these
+packets will carry a warning flag indicating this condition.
+
+==== SA Disablement and Destruction
+When it is time to retire an SA, the application does so by first issuing a
+call to the `odp_ipsec_sa_disable()` API. This call initiates termination
+processing for an SA by stopping use of the SA for new operations while still
+allowing those that are "in flight" to complete processing. Following this call
+the application continues to receive and process IPsec events as normal.
+
+Disable completion is indicated by the application seeing an event of type
+`ODP_EVENT_IPSEC_STATUS` for this SA that contains an `odp_ipsec_status_id_t`
+of `ODP_IPSEC_STATUS_SA_DISABLE`. For inbound SAs, receipt of this event means
+that the application has seen all IPsec packets associatd with this SA that
+were pending at the time of the disable call. For outbound SAs, receipt of
+this event means that the application has seen all result events associated
+with packets sent via this SA.
+
+Note that once a packet has been "seen" by the application, it becomes the
+application's responsibility to ensure that it is fully processed before
+attempting to destroy its associated SA. The disable call exists to give
+the application assurance that there are no pending IPsec events for this
+SA associated with packets that it has not seen before.
+
+So after disabling the SA, the application can process pending packets
+normally until it sees the disable status event. At that point it knows that
+all pending packets that arrived before the disable have been seen and it is
+safe for the application to destroy it via `odp_ipsec_sa_destroy()`, thus
+completing the SA lifecycle.

linux-gen: buffer: remove burst metadata from odp_buffer_hdr_t
The total packet meta data size was 7 cache lines for Linux-generic.
For scalable scheduler, the burst metadata is not required. So just
remove it for scalable scheduler. After the changes, the size of
the meta data is 4 cache lines for Linux-generic.
