lib: Clean up flow if alloc_res fails
|
| |
| |
| |
| |
| |
| |
| |
| |
| | |
If alloc_res fails all resources will be cleaned, except for the
assigned flow_descriptor, which must be released with a dealloc call.
Calling dealloc after a failed flow_alloc will not try to destroy the
already cleaned up flow in the IRMd and IPCPs.
Also fixes some memleaks in the oping client.

lib, ipcpd: Further stabilization of flows
|
|/
|
|
|

|
|
|
|
|
| |
The steps for flow deallocation have been further refined. An
operation ipcp_flow_fini() which wait for all SDUs to be read from a
flow has been added. The shim IPCPs and the local IPCP have been
adapted to this new API.
Deallocation messages have been removed from the shim IPCPs, since
there is insufficient state synchronisation between them to make this
work reliably.

ipcpd: shim-udp: Add check for directory entry
|
| |
| |
| |
| |
| |
| | |
A check was missing in the shim UDP if the destination was already
present in the directory, in which case no further queries were
needed.

tools: irm: Bind IPCP name to IPCP-I
|
| |
| |
| |
| | |
This fixes 2 wrong unlocks in the bind API method.
|
|/
|
|
|
|
| |
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.

irmd: Add log messages for flow allocation
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
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.

ipcpd: Fix memory leaks
|
| | | |
| | | |
| | | |
| | | |
| | | | |
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.

More fixes
|
| | | | |
| | | | |
| | | | |
| | | | |
| | | | | |
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.

dev, ipcp: Fix setting default flow options

The default flow options were not set when a flow allocation request
arrives remotely. This went unnoticed due to a previous bug.

Some fixes
|

| |
| |
| | |
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.
