This is a full revision of the IRMd internal implementation.
The registry is now a proper subcomponent managing its own internal
lock (a single mutex). Some tests are added for the registry and its
data structures. Some macros for tests are added in <ouroboros/test.h>.
Flow allocation is now more symmetric between the client side (alloc)
and server size (accept). Each will create a flow in pending state
(ALLOC_PENDING/ACCEPT_PENDING) that is potentially fulfilled by an
IPCP using respond_alloc and respond_accept primitives. Deallocation
is split in flow_dealloc (application side) and ipcp_flow_dealloc
(IPCP side) to get the flow in DEALLOC_PENDING and DEALLOCATED state.
Cleanup of failed flow allocation is now properly handled instead of
relying on the sanitizer thread. The new sanitizer only needs to
monitor crashed processes.
On shutdown, the IRMd will now detect hanging processes and SIGKILL
them and clean up their fuse mountpoints if needed.
A lot of other things have been cleaned up and shuffled around a bit.

The code was a bit convoluted to print hashes as hex strings. Renamed
to HASH_FMT32 and HASH_VAL32 to make clear we are printing the first
32 bits only, and added options to print 64 up to 512 bits as well.
This doesn't depend on endianness anymore. Adds a small test for the
hash (printing) functions.

The internal hash enum now matches the public one w.r.t. directory
hash policies. This removes some unnecessary conversion.

This adds the CRC check by default on outgoing SDUs. It fixes some
errors in the serialization and deserialization of the SDU. frct_clear
was added to avoid bad initialization of the array of FRCT instances.

This adds the basic FRCT mechanisms to the library. Upon flow alloc or
accept an FRCT instance is now created and used when reading or
writing to the flow. The timerwheel has been refactored to allow
recharging timers and removing them and is now part of the
library. The first SDU sent over the connection has the DRF set and
this initializes the connection. Sender and receiver inactivity timers
are added.

This adds support for libgcrypt. If at least version 1.7.0 of
libgcrypt is present, it may be used for secure random number
generation and is used for hashing in the irmd/ipcp.
The hash definitions are moved to the internal hash.h header, and
defined independently of the hashes that are defined as part of the
directory policy for the normal IPCP. The translation is moved from
the IRMd to ipcpd/ipcp.h. The bootstrap call from the IRMd expects the
IPCP to return the correct hash algorithm with a dif_info struct,
which is in line with the behavior of the enroll call.
This also improves how some platform checks in the build system are
handled.

The header ipcp.h was not installed systemwide, giving compile time
errors when trying to compile external programs that use irm.h. ipcp.h
also included hash.h, which exposes project interal functions. The
enum was moved to ipcp.h to prevent this.
|
|
|
|
| |
Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.
|

|
|
All information passed over the IRMd/IPCP boundary for using IPC
services (flow allocation, registration) is now hashed. This
effectively fixes the shared namespace between DIFs and the IRMDs.
This PR also fixes some API issues (adding const identifiers),
shuffles the include headers a bit and some small bugs.
