This will invoke the bind operation when using the irm tool to create
a new IPCP. The new IPCP will be bound to the IPCP name as specified
by the administrator.

ipcpd: Add threadpool for main loop
|
| |
| |
| |
| |
| |
| |
| | |
This adds a threadpool for the main loop of the IPCPs. Before there
was a single thread handling each request, which could result in
starvation since performing name queries at the same time as enrolling
a normal IPCP was impossible.

lib, irmd, ipcpd: Add name querying to IPCPs
|
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
This adds the ability to query IPCPs if a name can be reached through
them, e.g. if a name is available in a DIF. This means that in the
shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like
query has been added, in the local a check is done to see if the name
is registered, and in the normal currently no application is reachable
through it.

In the rewrite of the flow allocator for per-port ring buffers, the
messages were removed because they were not accurate anymore. This
adds messages when a port is allocated.

Fixes memory leaks associated with the dif_name (which doesn't need to
be maintained in shim DIFs) and the fqueue for the N + 1 flows.

lib: Stabilise flow allocation
|
| | | |
| | | |
| | | |
| | | |
| | | | |
Remote requests for a flow that's locally deallocated should not
generate an error. Sending messages should not be under lock.
|
| | | |
| | | |
| | | |
| | | | |
This solves some potential data races in the shims.

Deallocation was reverted to a synchronoous operation between the AP,
IRMd and IPCP in order to avoid inconsistent states of the port_id.
Fixes some memory leaks, particularly the shm_flow_set is now closed
upon deallocation.
|
|
|
|
|
| |
The default flow options were not set when a flow allocation request
arrives remotely. This went unnoticed due to a previous bug.

gethostbyname is included in POSIX 2001. Ouroboros requires at least
POSIX 2001 and recommends POSIX 2008 for stable builds.

The rdrbuff was previously closed before the remaining SDUs were removed.

An untested (and wrong) modification to the fqueue was mistakenly
added to a previous commit. This corrects the bad code.

FLOW_O_RDONLY is 0, so the previous statement would always be false.

CheckLibraryExists was not included. Apparently the
CHECK_FUNCTION_EXISTS call fails with the strict prototyping flag
turned on.

This has the code checked with -Wcast-qual and -Wconversion flags.
These flags were removed because SWIG generated code fails.

This reduces the risk for some bugs, for instance due to
signed/unsigned mismatches and unused variables.

lib: Demultiplex the fast path
|
| |
| |
| |
| |
| | |
This stabilises flow allocation now that the rbuffs are created upon
flow allocation. Only the IRMd can sync this process sufficiently.
|
| |
| |
| |
| |
| |
| |
| |
| | |
The fast path will now use an incoming ring buffer per flow per
process. This necessitated the development of a new method for the
asynchronous io call, which is now based on an event queue system for
scalability (fqueue). The ipcpd's and tools have been updated to this
API.

There was no check to see if the normal IPCP was enrolled or not when
a flow allocation request is done.
|
|
|
|
|
|
|
| |
Added the missing implementation of setting read/write options for
flows. This allows applications to block the fast path for
remotes. IPCPs can use this to block the fast path for the N + 1 flow
when receiving remote deallocation requests.
|
| |
|

|

The safe copy was not correctly initialised.
|

Both the N and N-1 entity must now call flow_dealloc for the port_id
to be released.

This commit will remove the RMT component from the normal IPCP, as
some of its functionality would else be duplicated in the FMGR. Now
all reading from flows, either N-1 or N+1 is done in the FMGR, then
either passed to the FRCT or a lookup is performed in the PFF (not
there yet) and the PDU is forwarded.

This will allow to finalize deallocating flows until all SDUs have
been processed. Read and write calls will now block when a flow was
deallocated. Replaces NULL checks in the fast path with asserts.
|
| |
| |
| |
| |
| |
| | |
The struct flow_set can now be accessed in applications as flow_set_t.
Fixes some malformed lines and homogenizes output when receiving bad
SDUs in the oping tool.

This is the first version of the fast path bootstrap in the normal
IPCP. It sets up a connection with the other end, and creates the
appropriate data structures. N+1 and N-1 SDUs are read and written and
passed through the right components.

Flow deallocation from the application will immediately return (void
call). The IRMd will not send a reply message.

The SDU's were not correctly removed upon shutdown, peek should be
pop.

Now correctly handles and drops non-ouroboros traffic.

Upon deallocation, the remote's SAP was being used to lookup the fd
instead of our own SAP. This resulted in strange behaviour.
|
|
|
|
|
|
| |
Some locks were taken at an inappropriate time, causing the
shim-eth-llc to block indefinitely upon shutdown and causing flow
allocation to halt since a response could never be given.

IPCPs can now use ap_init() to initialize the memory. All flows are
accessed using flow descriptors, this greatly simplifies IPCP
development. Reverts the fast path to a single ap_rbuff per process.
Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev
holding tailored functions for shims. Moves the buffer_t to utils.h.
Fixes the shim-eth-llc length field. Removes the flow from shared.h.

Cupertino's finest don't seem to support a write call with a
filedescriptor that points to a shared memory file. ENOTSUP is not
mentioned in their manpage either. Classic.
