+Subject: [PATCH] feat: disable alignment check for EL0 partitions
+
+Relax hw alignment check specifically for (S-)EL0 partitions when
+Hafnium runs with VHE enabled. EL1 partitions have a specific control
+for EL1 and EL0 with respect to alignment check.
+Create a hyp_state structure (from already defined flying registers)
+within the vCPU context to hold the Hypervisor EL2 static configuration
+applied when a vCPU runs. This state is switched back and forth when
+running the Hypervisor or the VM.
+Add SCTLR_EL2 to this context. An EL0 partition context is initialized
+with SCTLR_EL2.A=0 such that alignment check is disabled when EL0 runs
+in the EL2&0 translation regime. SCTLR_EL2.A is set back when returning
+to the Hypervisor such that Hypervisor execution runs with aligment
+check enabled at EL2.
+Remove HCR_EL2 saving from vCPU exit path provided this register state
+is static and doesn't change while a vCPU runs.
+The rationale for such change is to permit running upstream SW stacks
+such as the EDKII/StandaloneMm [1] for which default build assumes
+unaligned accesses are permitted. Similar query exists for running
+Trusted Services on top of Hafnium [2].

+Subject: [PATCH] feat(vhe): set STAGE1_NS while mapping memory from NWd to SWd
+
+If the memory is shared by a VM executing in non secure world, attribute
+MM_MODE_NS had to be set while mapping that in a S-EL0 SP executing in
+secure world. It will not be needed for a S-EL1 SP since the NS bit is
+available only for the stage 1 translations and the stage 1 translations
+for a S-EL1 SP will be handled by a trusted OS running in S-EL1.

-
-Reserve static shared-dma-pool below 4GB. This removes dependency on
-SMMU driver. As there are stability issues in SMMU driver, it is
-disabled. This change is temporary and will be reverted upon proper
-fix and testing.

-Subject: [PATCH 08/24] arm_ffa: introducing MM communication with FF-A
-
-This commit allows to perform MM communication using FF-A transport.
-
-The MM SP (also called partition) can be StandAlonneMM or smm-gateway.
-Both partitions run in OP-TEE.
-
-When using the u-boot FF-A driver, StandAlonneMM and smm-gateway are
-supported.
-
-On EFI services such as GetVariable()/SetVariable(), the data
-is copied from the communication buffer to the MM shared buffer.
-
-Then, notifies the MM SP about data availability in the MM shared buffer.
-Communication with the MM SP is performed using FF-A transport.
-
-On such event, MM SP can read the data and updates the MM shared buffer
-with response data.
-
-The response data is copied back to the communication buffer.

+Subject: [PATCH 09/26] arm_ffa: introduce Arm FF-A low-level driver
+
+Add the driver implementing Arm Firmware Framework for Armv8-A v1.0
+
+The Firmware Framework for Arm A-profile processors (FF-A)
+describes interfaces (ABIs) that standardize communication
+between the Secure World and Normal World leveraging TrustZone
+technology.
+
+This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
+on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
+querying the FF-A framework from the secure world.
+
+32-bit version of the ABIs is supported and 64-bit version of FFA_RXTX_MAP
+and FFA_MSG_SEND_DIRECT_{REQ, RESP}.
+
+In u-boot FF-A design, FF-A is considered as a discoverable bus.
+The Secure World is considered as one entity to communicate with
+using the FF-A bus. FF-A communication is handled by one device and
+one instance (the bus). This FF-A driver takes care of all the
+interactions between Normal world and Secure World.
+
+The driver exports its operations to be used by upper layers.
+
+Exported operations:
+
+- partition_info_get
+- sync_send_receive
+- rxtx_unmap
+
+This implementation provides an optional feature to copy the driver data
+to EFI runtime area.

++Arm FF-A Driver
++====================
++
++Introduction
++--------------------
++
++FF-A stands for Firmware Framework for Arm A-profile processors.
++
++FF-A specifies interfaces that enable a pair of software sandboxes to communicate with each other. A sandbox aka partition could
++be a VM in the Normal or Secure world, an application in S-EL0, or a Trusted OS in S-EL1.
++
++This FF-A driver implements the interfaces to communicate with partitions in the Secure world aka Secure partitions (SPs).
++
++The driver specifically focuses on communicating with SPs that isolate portions of EFI runtime services that must run in a
++protected environment which is inaccessible by the Host OS or Hypervisor. Examples of such services are set/get variables.
++
++FF-A driver uses the SMC ABIs defined by the FF-A specification to:
++
++- Discover the presence of SPs of interest.
++- Access an SP's service through communication protocols e.g. EFI MM communication protocol.
++
++FF-A and SMC specifications
++-------------------------------------------
++
++The current implementation of the driver relies on FF-A specification v1.0 and uses SMC32 calling convention.
++
++The driver has been tested with Optee OS which supports SMC32 for most of the SMC ABIs.
++
++For more details please refer to: https://developer.arm.com/documentation/den0077/a/?lang=en
++
++The FF-A driver uses 64-bit registers as per SMCCCv1.2 specification.
++
++For more details please refer to: https://documentation-service.arm.com/static/5f8edaeff86e16515cdbe4c6?token=
++
++Supported hardware
++--------------------------------
++
++Aarch64 plaforms
++
++Configuration
++----------------------
++
++CONFIG_ARM_FFA_TRANSPORT
++    Enables the FF-A bus driver. Turn this on if you want to use FF-A communication.
++
++CONFIG_ARM_FFA_EFI_RUNTIME_MODE
++    Optional config that enables EFI runtime support for FF-A data and code.
++    ffa_copy_runtime_data allows to copy the FF-A driver data structures to EFI runtime data section.
++    Turning the config on makes ffa_copy_runtime_data available for use and the driver code placed at EFI runtime code section.
++    Call ffa_copy_runtime_data at the event on which you want the FF-A data to be copied (example: at ExitBootServices).
++
++CONFIG_SANDBOX_FFA
++    Enables FF-A Sandbox driver. This emulates the FF-A ABIs handling under Sandbox and provides
++    functional tests for FF-A.
++
++FF-A ABIs under the hood
++---------------------------------------
++
++Invoking an FF-A ABI involves providing to the secure world/hypervisor the expected arguments from the ABI.
++
++The ABI arguments are stored in x0 to x7 registers. Then, an SMC instruction is executed.
++
++At the secure side level or hypervisor the ABI is handled at a higher exception level and the arguments are read and processed.
++
++The response is put back through x0 to x7 registers and control is giving back to the u-boot FF-A driver (non secure world).
++
++The driver reads the response and processes it accordingly.
++
++This methodology applies to all the FF-A ABIs in the driver.
++
++FF-A bus discovery in u-boot
++-------------------------------------------
++
++When CONFIG_ARM_FFA_TRANSPORT is enabled, the FF-A bus is automatically discovered at initcall level (after u-boot relocation).
++
++The function that triggers the discovery process is ffa_bus_discover.
++
++ffa_bus_discover creates, binds and probes the arm_ffa device using device_{bind, probe} APIs.
++
++When the device is probed, ffa_probe is called which tries to communicate with the secure world or hypervisor.
++
++The FF-A bus is usable when these checks succeed:
++
++- querying the FF-A framework version
++- querying from secure world the u-boot endpoint ID
++- querying from secure world the supported features of the specified FF-A calls
++- mapping the RX/TX buffers
++- querying from secure world all the partitions information
++
++Probing fails when any of these operations fail. The FF-A bus discovery succeeds when probing is successful.
++
++When discovery fails the arm_ffa device is destroyed.
++
++The bus driver layer
++------------------------------
++
++The driver comes on top of the SMCCC layer and is implemented in drivers/firmware/arm-ffa/core.c
++
++The driver provides the following features:
++
++- Support for the 32-bit version of the following ABIs:
++
++FFA_VERSION
++FFA_ID_GET
++FFA_FEATURES
++FFA_PARTITION_INFO_GET
++FFA_RXTX_UNMAP
++FFA_RX_RELEASE
++FFA_RUN
++FFA_ERROR
++FFA_SUCCESS
++FFA_INTERRUPT
++
++- Support for the 64-bit version of the following ABIs:
++
++FFA_RXTX_MAP
++FFA_MSG_SEND_DIRECT_REQ
++FFA_MSG_SEND_DIRECT_RESP
++
++- Processing the received data from the secure world/hypervisor and caching it
++
++- Hiding from upper layers the FF-A protocol and registers details. Upper layers focus on exchanged data,
++the driver takes care of how to transport that to the secure world/hypervisor using FF-A.
++
++- The driver provides callbacks to be used by clients to access the FF-A bus:
++
++partition_info_get
++sync_send_receive
++rxtx_unmap
++
++- FF-A bus discovery at initcalls level (after u-boot relocation). The bus is up and running if the FF-A framework is responsive and compatible with the driver.
++
++- When EFI is enabled, unmap the RX/TX buffers at ExitBootServices() level.
++
++- When CONFIG_ARM_FFA_EFI_RUNTIME_MODE enabled, ffa_copy_runtime_data function is available for use.
++
++Using armffa command
++-----------------------------------
++
++armffa is a command showcasing how to use the FF-A driver and how to invoke its operations.
++
++This provides a guidance to the client developers on how to call the FF-A bus interfaces.
++
++Usage:
++
++armffa <sub-command> <arguments>
++
++sub-commands:
++
++        getpart <partition UUID>
++
++            lists the partition(s) info
++
++        ping <partition ID>
++
++            sends a data pattern to the specified partition
++
++        devlist
++
++            displays the arm_ffa device info

++ * The passed arguments:
++ * Mode 1: When getting from the driver the number of
++ *	secure partitions:
++ *	@uuid_str: pointer to the UUID string
++ *	@parts_size: pointer to the variable that contains the number of partitions
++ *			 The variable will be set by the driver
++ *	@buffer: NULL
++ *
++ * Mode 2: When requesting the driver to return the
++ *	partitions information:
++ *	@uuid_str: pointer to the UUID string
++ *	@parts_size: pointer to the size of the SPs information buffer in bytes
++ *	@buffer: pointer to SPs information buffer
++ *		(allocated by the client).
++ *		The buffer will be filled by the driver
++ *
++ * This is the boot time function that queries the secure partition data from
++ * the private data structure. If not found, it invokes FFA_PARTITION_INFO_GET
++ * FF-A function to query the partition information from secure world.
++ *
++ * A client of the FF-A driver should know the UUID of the service it wants to
++ * access. It should use the UUID to request the FF-A driver to provide the
++ * partition(s) information of the service. The FF-A driver uses
++ * PARTITION_INFO_GET to obtain this information. This is implemented through
++ * ffa_get_partitions_info function.
++ * A new FFA_PARTITION_INFO_GET call is issued (first one performed through
++ * ffa_cache_partitions_info) allowing to retrieve the partition(s) information.
++ * They are not saved (already done). We only update the UUID in the cached area.
++ * This assumes that partitions data does not change in the secure world.
++ * Otherwise u-boot will have an outdated partition data. The benefit of caching
++ * the information in the FF-A driver is to accommodate discovery after
++ * ExitBootServices().
++ *
++ * When invoked through a client request, ffa_get_partitions_info should be
++ * called twice. First call is to get from the driver the number of secure
++ * partitions (SPs) associated to a particular UUID.
++ * Then, the caller (client) allocates the buffer to host the SPs data and
++ * issues a 2nd call. Then, the driver fills the SPs data in the pre-allocated
++ * buffer.
++ *
++ * To achieve the mechanism described above, ffa_get_partitions_info uses the
++ * following functions:
++ *		ffa_read_partitions_info
++ *		ffa_query_partitions_info
++ *
++ * Return:
++ *
++ * @parts_size: When pointing to the number of partitions variable, the number is
++ * set by the driver.
++ * When pointing to the partitions information buffer size, the buffer will be
++ * filled by the driver.

+From: Abdellatif El Khlifi <abdellatif.elkhlifi@arm.com>
+Date: Mon, 6 Jun 2022 12:55:08 +0100
+Subject: [PATCH 11/26] arm_ffa: introduce the FF-A Sandbox driver
+
+Provide a Sandbox driver to emulate the FF-A ABIs
+
+The emulated ABIs are those supported by the FF-A core driver
+and according to FF-A specification v1.0.
+
+The Sandbox driver provides operations allowing the test
+application to read the status of all the inspected ABIs
+and perform functional tests based on that.
+
+Signed-off-by: Abdellatif El Khlifi <abdellatif.elkhlifi@arm.com>
+Upstream-Status: Submitted [cover letter: https://lore.kernel.org/all/20220926101723.9965-1-abdellatif.elkhlifi@arm.com/]
+---
+
+Changelog:
+===============
+
+v4: align sandbox driver with the new FF-A driver interfaces
+ and new way of error handling
+
+v1: introduce the sandbox driver

-Subject: [PATCH 13/24] corstone1000: Make sure shared buffer contents are not
- cached
-
-After updating the shared buffer, it is required to flush the cache
-to ensure that the secure world sees expected the shared buffer
-contents.
-
-The MM communication shared buffer is configured in device region of optee
-which has cache disabled. So we need to invalidate the cache every time we
-update the buffer on uboot otherwise the secure world does not see the
-accurate values.

+Subject: [PATCH 14/26] arm_ffa: introduce FF-A MM communication
+
+Add MM communication support using FF-A transport
+
+Access an SP's service through EFI MM communication protocol.
+
+This feature allows accessing MM partitions services through
+EFI MM communication protocol. MM partitions such as StandAlonneMM
+or smm-gateway secure partitions which reside in secure world.
+
+An MM shared buffer and a door bell event are used to exchange
+the data.
+
+The data is used by EFI services such as GetVariable()/SetVariable()
+and copied from the communication buffer to the MM shared buffer.
+
+The secure partition is notified about availability of data in the
+MM shared buffer by an FF-A message (door bell).
+
+On such event, MM SP can read the data and updates the MM shared
+buffer with the response data.
+
+The response data is copied back to the communication buffer and
+consumed by the EFI subsystem.
+
+FF-A driver private data is copied to EFI runtime section at
+ExitBootServices(). This garantees secure world partitions data are
+available at EFI runtime level.

+
+Changelog:
+===============
+
+v4:
+
+* use the new FF-A driver interfaces
+* discover MM partitions at runtime
+* copy FF-A driver private data to EFI runtime section at
+  ExitBootServices()
+* drop use of FFA_ERR_STAT_SUCCESS error code
+* replace EFI_BUFFER_TOO_SMALL by EFI_OUT_OF_RESOURCES
+  in ffa_mm_communicate(). No need for efi_memcpy_runtime() anymore
+* revert the error log in mm_communicate() in case of failure
+* remove packed attribute from efi_mm_communicate_header and
+  smm_variable_communicate_header
+
+v2:
+
+* set default values to 0 for FFA_SHARED_MM_BUFFER_SIZE, FFA_SHARED_MM_BUFFER_ADDR and MM_SP_UUID_DATA and add warnings
+
+v1:
+
+* introduce FF-A MM communication

+Subject: [PATCH 5/7] efi_firmware: add new fmp driver that supports arm fwu
+ specification
+
+This fmp driver communicates to the firmware update secure partition
+executing in the secure world which is an implementation of the arm
+psa specification for the firmware update. The communication to the
+firmware update secure partition is based on stmm and arm ff-a framework.
+
+It implements only the get_image_info and set_image api.

+Subject: [PATCH 7/7] arm_ffa: unmap rxtx buffer before exiting u-boot
+
+The linux kernel ffa driver will be used after the kernel boots. It
+will try to map its own rxtx buffer. But there can be only one rxtx
+buffer mapped from the non secure world. Since the rxtx buffer of
+the u-boot is no longer used and we have to map the rxtx buffer of
+the linux kernel, the rxtx buffer of the u-boot should be unmapped.
+
+This will not be needed after the efi runtime services are enabled

+Subject: [PATCH 3/3] Platform/ARM/N1Sdp: Modify the IRQ ID of Debug UART and
+ routing it to IOFPGA UART1
+
+In DBG2 table, IRQ ID was set as 0 for the UART. This overwrote the
+IPI0 trigger method to "level", which prevented SGI0 to be enabled
+again after a CPU offline/online cycle.
+
+This patch fixes the above issue by assigning a reserved IRQ ID
+for the Debug UART, other than 0 and also routing it to use IOFPGA
+UART1 by unsharing it from currently using serial terminal.

+Subject: [PATCH] optee: enable clang support
+
+When compiling with clang, the LIBGCC_LOCATE_CFLAG variable used
+to provide a sysroot wasn't included, which results in not locating
+compiler-rt. This is mitigated by including the variable as ammended.

+Subject: [PATCH] core: link: add --no-warn-rwx-segments
+
+Signed-off-by: Anton Antonov <Anton.Antonov@arm.com>
+Upstream-Status: Backport [https://github.com/OP-TEE/optee_os/pull/5474]
+
+binutils ld.bfd generates one RWX LOAD segment by merging several sections
+with mixed R/W/X attributes (.text, .rodata, .data). After version 2.38 it
+also warns by default when that happens [1], which breaks the build due to
+--fatal-warnings. The RWX segment is not a problem for the TEE core, since
+that information is not used to set memory permissions. Therefore, silence
+the warning.
+
+Link: [1] https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=ba951afb99912da01a6e8434126b8fac7aa75107

-Subject: [PATCH] Fix: add missing error check during SP init
-
-Error checking during SP initialization (sp_init_uuid()) was lacking.
-As a result an out of CORE HEAP situation resulted in a panic. This was
-due to lack of memory in the inflate() function of zlib.

-Subject: [PATCH] Add UEFI variable support for QueryVariableInfo
-
-Adds support for the UEFI QueryVariableInfo operation. The total
-store size currently relies on pre-configured values, set for a
-particular deployment. Ideally, this information would be read
-from the storage backend. This facility is not however yet
-supported by the storage backend interface or by any PSA
-storage backend storage providers.

-Subject: [PATCH] Support FFARPC call requests with no shared buffer
-
-To allow simple clients to make RPC calls for service operations
-that take no request parameters and return no response parameters,
-the ffarpc_call_ep.c has been modified to accept call requests
-when no shared buffer exists, as long as there is no request data.

-Subject: [PATCH] Increase SMM gateway UEFI variable macro value
-
-The maximum number of UEFI variables that be supported by SMM
-gateway is currently 40. When more than 40 variables are written,
-or read SMM gateway returns error code. Currently this value is
-increased to 100 to support more UEFI variables.

-Subject: [PATCH] Change UID of variable index in SMM
-
-This patch fixes the os_indications setVariable() failure. The variable
-index UID in SMM gateway which was 1 is changed in this patch. TFM has a
-special usage for variable with UID 1, which makes it write once only.
-This is not required for SMM variable index.

-Subject: [PATCH] Enhance mbedtls fetch process
-
-Update management of MbedTLS external component to be optimized
-for download speed insted of availability.
-The updated process is:
-  - check if binary is available. If yes configure build to use it
-    and stop.
-  - if not, check is source is available. If yes, build it and use
-    the resulting binary.
-  - if not, then download the source using git, compile it and use
-    the resulting binary
-
-The following variables can be set on the command line to alter the
-behavior of the module:
-  - MBEDTLS_URL git repo URL to fetch from.
-  - MBEDTLS_REFSPEC revision to fetch
-  - MBEDTLS_SOURCE_DIR to specify location of source code in
-    local file syetem.
-  - MBEDTLS_INSTALL_DIR to specify location of binary.
-
-I.e. cmake -S <...> -B <...> -DMBEDTLS_INSTALL_DIR=~/mbedtls
-will make the resulting binary installed to ~/mbedtls. This can be
-used later to speed up a clean build an use the prebuilt binary.

-
-A previous change increased the width of the opstatus value

-corrects the printf format specifier in the rpc logging_caller
-that corresponds to logging the opstatus value.

-Subject: [PATCH] Separate sign/verify message and hash operations
-
-Previous versions of mbedtls didn't distinguish between
-asymmetric sign and verify operations on a hash or message.
-They are now treated as separate operations from a usage
-control perspective. This change makes the corresponding
-hash/message sepration in client and service provider
-components.

-Subject: [PATCH] Add IV generation to one-shot cipher operation
-
-The functions psa_cipher_encrypt and psa_cipher_decrypt are
-one-shot operations that can take an arbitrary sized input.
-These operations are implemented as client-side functions
-that use multi-part cipher operations to allow large inputs
-to be handled. The existing implementations were missing the
-generation and setting of the IV at the start of the data.
-This was leading to PSA Arch test failures (248 & 249). This
-commit adds the missing IV handling and resolves the test
-failures.

-Subject: [PATCH] Fix multi-part termination on error
-
-For multi-part operations, the PSA Crypto API specifies that if
-the final operation does not return PSA_SUCCESS, the abort
-operaion must be called by a client to clean-up the operation.
-This change modifies behaviour in-line with the API definition.

-Subject: [PATCH] Abort AEAD operation if client provided buffer is too small
-
-To enable PSA Arch test c258 to pass, handling is added in the
-PSA API client adaptor for AEAD (psa_aead.c) to abort an AEAD
-operation if an update operation is performed but the client
-provided buffer for the output is too small.

-Subject: [PATCH] Peg to updated t_cose version fc3a4b2c
-
-The current version of TS fails to build due to a regression introduced
-by a new t_cose version in the upstream project.
-The issue is caused by the t_cose external component incorrectly using
-tip of master as the upstream version id, which makes strict dependency
-control impossible. Change the upstream version id to an SHA, to enable
-controlling compatibility issues introduced by future upstream updates.
-
-At the same time update the dependency to the current latest version.
-The upstream project is now compatile with mbedtls 3.0.0 API changes
-so the previously required compatibility patch has been removed.

-Subject: [PATCH] Fix UEFI get_variable with small buffer
-
-The handling of the UEFI get_variable operation was incorrect when
-a small or zero data length was specified by a requester. A zero
-length data length is a legitimate way to discover the size of a
-variable without actually retrieving its data. This change adds
-test cases that reproduce the problem and a fix.

-Subject: [PATCH] core, ldelf: link: add -z execstack
-
-When building for arm32 with GNU binutils 2.39, the linker outputs
-warnings when generating some TEE core binaries (all_obj.o, init.o,
-unpaged.o and tee.elf) as well as ldelf.elf:
-
- arm-poky-linux-gnueabi-ld.bfd: warning: atomic_a32.o: missing .note.GNU-stack section implies executable stack
- arm-poky-linux-gnueabi-ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
-
-The permissions used when mapping the TEE core stacks do not depend on
-any metadata found in the ELF file. Similarly when the TEE core loads
-ldelf it already creates a non-executable stack regardless of ELF
-information. Therefore we can safely ignore the warnings. This is done
-by adding the '-z execstack' option.

-Subject: [PATCH] arm32: libutils, libutee, ta: add .note.GNU-stack section to
-
- .S files
-
-When building for arm32 with GNU binutils 2.39, the linker outputs
-warnings when linking Trusted Applications:
-
- arm-unknown-linux-uclibcgnueabihf-ld.bfd: warning: utee_syscalls_a32.o: missing .note.GNU-stack section implies executable stack
- arm-unknown-linux-uclibcgnueabihf-ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
-
-We could silence the warning by adding the '-z execstack' option to the
-TA link flags, like we did in the parent commit for the TEE core and
-ldelf. Indeed, ldelf always allocates a non-executable piece of memory
-for the TA to use as a stack.
-
-However it seems preferable to comply with the common ELF practices in
-this case. A better fix is therefore to add the missing .note.GNU-stack
-sections in the assembler files.

+
+The script build_OID_registry captures the full path of itself
+in the generated data. This causes reproduciblity issues as the
+path is captured and packaged.
+
+We use the basename of the script instead, and that allows us
+to be reprodicible, with slightly less information captured in
+the output data (but the generating script can still easily
+be found).

+Subject: [PATCH 2/2] vt/conmakehash: improve reproducibility
+
+The file generated by conmakehash capture the application
+path used to generate the file. While that can be informative,
+it varies based on where the kernel was built, as the full
+path is captured.
+
+We tweak the application to use a second input as the "capture
+name", and then modify the Makefile to pass the basename of
+the source, making it reproducible.
+
+This could be improved by using some sort of path mapping,
+or the application manipualing argv[1] itself, but for now
+this solves the reprodicibility issue.

+Date: Thu, 8 Sep 2022 16:14:36 -0400
+Subject: [PATCH] bgpd: avoid notify race between io and main pthreads
+
+The "bgp_notify_" apis in bgp_packet.c generate a notification
+to a peer, usually during error handling. The io pthread wants
+to send notifications in a couple of cases during early
+received-packet validation - but the existing api interacts
+with the peer struct itself, and that's not safe.
+
+Add a new api for use by the io pthread, and adjust the main
+notify api so that it can avoid touching the peer struct.

+
+It is not possible to build ospf_spf.c file with --disable-ospfapi because
+ospf_apiserver.c has SUPPORT_OSPF_API around all function definitions and
+that results in an undefined reference to the ospf_apiserver_notify_reachable
+function error while building.

-Subject: [PATCH] Support musl libc, remove support for glibc < 2.1
-
-Upstream-Status: Backport
-
-The workarounds for glibc < 2.1 (was released february 1999) break the
-build with musl libc.
-
-It is very unlikely that 2.0 or earlier is still in use, and if so,
-1) that's a big security hole
-2) code wouldnt compile anyway since noone tested build in the last decade
-3) user of it wouldn't expect anyway to get bleeding edge sw built on it,
-   so he would just use the latest version that works for him.
-
-Closes #52

-about this kind of multiple definition.
