* Change yield from ptr to objectJames Feist2019-09-131-1/+1
| | | | | | | | | | | | The ptr makes for ugly code: i.e. *(ctx->yield) all over the place. Change it to copy as it is just 4 pointers. Tested: ipmitool mc info still works Change-Id: I30c5bc395849875cd58925fac99bb23c1804cd5b Signed-off-by: James Feist <james.feist@linux.intel.com>
* legacy handlers need a bigger bufferVernon Mauery2019-08-301-4/+3
| | | | | | | | | | | | | | | | | In the original ipmi execution queue, handlers were passed a larger buffer. The current code was only passing in the configured channel size, or 64 if no size was configured. This is too small and leads to buffer overflows for responses greater than 64 bytes. This brings the buffer sizes up to a point that matches the legacy code and to a size that is larger than any of IPMI standard transport sizes. Tested: used a bogus handler to create a large response and found that the entire response was returned.

* handler: Fix request passing for legacy commandsWilliam A. Kennington III2019-04-291-7/+10
| | | | | | | | | | | | | | | | Legacy OEM commands didn't handle the IANA numbers themselves as part of their handler body, and expect the request buffer to not contain them. We can't pass the raw buffer without removing the already extracted prefixes. This should make legacy OEM commands work again. Also reworks group handling to become consistent with OEM handling. This happens to fix cases where groupIds were not being returned with error codes. Change-Id: I10efe8004f2c2b262f48980852b46317035ca367 Signed-off-by: William A. Kennington III <wak@google.com>
* message/payload: Ignore unchecked unpack warning during unwindWilliam A. Kennington III2019-04-291-33/+35
| | | | | | | | | | | If we are caught in an exception unwind we don't care that the payload is not be fully checked. Otherwise, this encourages the pattern of wrapping all handler code in try catch blocks that set trailingOk as it is not required to read the entire payload when throwing an exception.

* message/payload: Clean up check / trailing stateWilliam A. Kennington III2019-04-291-0/+1
| | | | | | | | | | | | | | | | We want to be able to trivially re-use payloads for marshalling data from a buffer into other formats. This change tries to make the meaning of trailingOk and unpackCheck consistent, since the meanings didn't seem clear in the previous code. Now, unpackCheck is only used to determine if unpacking was checked, and trailingOk determines if unpackCheck is required. This also fixes lots of spurious warnings being printed for commands which were checking their output correctly, or were legacy and unable to check output.

* Only include ipmid/api.hpp for the new APIVernon Mauery2019-04-081-1/+133
| | | | | | | | | | | | | | After some feedback from users of the new IPMI API, they wanted to see two things: 1) don't require ipmid/api.hpp and ipmid/registration.hpp to be able to write new handlers 2) only require including ipmid/api.hpp (instead of ipmid/api.h) So now, by simply including ipmid/api.hpp instead of ipmid/api.h (deprecated), handlers incorporating the new IPMI API can be written.

* Add user context parameter to legacy ipmi handler registrationVernon Mauery2019-03-211-4/+7
| | | | | | | | | This part was originally omitted, but needed by some external provider libraries. This will more closely mimic the behavior of ipmid prior to the architecture update. Change-Id: I5db35222e268a117480285c700d88206d6505d92 Signed-off-by: Vernon Mauery <vernon.mauery@linux.intel.com>
* errorResponse must not pack completion code in data payloadVernon Mauery2019-03-151-3/+3
| | | | | | | | | | | | | Until the response goes back out onto D-Bus, the completion code is held in a separate part of the Response object. The D-Bus response has a separate field for the completion code as well, reserving a byte array for response data only. This fixes the ipmitool error message 'Bad response length, len=1' when it attempts to query the PICMG capabilities.

* ipmid: Add in Native OEM and Group OEM supportVernon Mauery2019-02-251-0/+106
| | | | | | | | | | Add full support for the IPMI OEM NetFn and the Group OEM support as defined in the IPMI 2.0 specification. For now the legacy OEM router mechanism is still supported.

* ipmid: Compiler-generated unpacking and packing of messagesVernon Mauery2019-02-251-0/+396
handler.hpp has the templated wrapping bits for ipmi command handler callbacks implemented. message.hpp has the serialization/deserialization of the ipmi data stream into packed tuples for functions. message/pack.hpp and message/unpack.hpp contain the actual serialization and deserialization of types.
