ipcpd: Fix locking of shim-eth-llc
|
| |
| |
| |
| |
| |
| | |
This changes the amount of time the shim-eth-llc will hold the IPCP
state lock when sending and receiving frames. Before it was holding
the lock for too long.
|
|/
|
|
| |
Locks should be kept before calling cond_wait.
|
|
|
|
|
|
|
| |
Refactors the IRMd to extract reg_api and irm_flow structures to their
own sources.
Fixes some locking bugs.
|

|
|
| |
When the rbuff was empty, the blocking read would wait forever for a
read.
|
|
|
|
|
|
| |
This adds the functionality of exchanging the static DIF information
between 2 DIF members. After exchange the enrollment is stopped, and
the IPCP that initiated enrollment transitions to the enrolled state.
|
|
|
|
|
| |
Sometimes the POSIX version was not set in source files. This caused
the compiler to not find the timespec struct, since we are using C89.
|
| |
|
| |
|
|
|
|
| |
Padding was miscalculated, causing lockups in the fast path.
|
|
|
|
| |
The req_ae_name is freed when the unpacked message is cleaned up.
|
|
|
|
| |
The entry from the ringbuffer was never freed, causing memleak per SDU.
|
|
|
|
| |
The check whether the du map is empty should be first.
|
| |
|
| |
|
| |
|
|
|
|
|
| |
When cancelled in read() the fd should be closed and the allocated
memory freed.

The server should cleanup whenever the listen thread exits.

The server should cleanup whenever the listen thread exits.

If ap_init() fails, the program should exit.
|
|
|
|
| |
The server apn is a client-only option. Also fixes some indentation.

When killing the oping client before it sent an SDU, some bad
operations were being performed.
|
| |
|
|
|
|
|
| |
When a flow was in FLOW_ALLOCATED state, it would not change to NULL
state and irm_flow_destroy would hang forever.
|
|
|
|
| |
ipcp-data was not correctly destroyed.
|
|
|
|
| |
The cleanup was trying to close a pointer to the file descriptor.
|
|
|
|
|
|
|
|
|
| |
Blocking I/O now uses condition variables in the shared memory instead
of busy waiting. Timeouts can be specified. This requires the size of
the rbuffs and du_map to be the same, to guarantee that when the
shm_du_map is not full, the ap_rbuffs can't be full either.
Added the timeout option to the flow for future use.
|
|
|
|
|
| |
Ouoroboros ping application mimics the GNU ping application.
do "oping --help" for options.
|
|
|
|
|
|
|
| |
This adds a flow_select() call that will sleep until an SDU can be
read on a flow. It returns the file descriptor for which an SDU is
ready. It takes as optional argument a timespec struct to specify a
timeout.

shim-eth-llc: Fix for bad drivers
|
| |
| |
| |
| |
| |
| |
| |
| | |
It seems like drivers are setting the Ethernet length field wrong when
sending an LLC message. The LLC shim now writes the payload length in
the frame to circumvent the wrong information from the driver.
Also fixes deallocation.

Be enrolment
|
| |
| |
| |
| |
| |
| |
| | |
This will add more functionality for enrolling two normal IPCPs with
each other. Some bugs were fixed in CDAP. Now on enrolling, an IPCP
will send a START message to the other IPCP. Next step is syncing the
RIBs.

This provides the normal IPCP with bootstrapping and the initial steps
for enrollment. Next step is actually reacting to an enrollment
request and sending the data transfer constants.

Various portability fixes for FreeBSD. POSIX requires shm file names
to start with a "/" to be portable. lseek(2) can be undefined on
POSIX shm, replaced with ftruncate(2). IRMd check on existing lockfile
more portable.
FreeBSD 11.0 is preferred as it natively supports robust mutexes.
Full working LLC implementation pending.

Upon receipt of a frame, the minimum of the length reported in the
frame and the frame length reported by kernel is taken. Some device
drivers change the length in the frame. Some others add padding,
making the length reported by the kernel too high. This is a lousy
workaround to make it work on as many systems as possible.

It was missing the FLOW_PENDING state. All states that are not
FLOW_ALLOCATED should return -1. This is now fixed.

When a pending accept is shutdown on irmd exit, there are no more
threads running, but it should also change the state to NULL. This is
now correctly handled in the cleanup of the cancellation point.
Also fixed a busy wait with a condition variable.

irmd: Revised flow allocation
|
| |/
| |
| |
| |
| |
| |
| |
| |
| | |
Flow allocation requests and registered api states revised so all
states are tracked with a condition variable. This is a more reliable
approach and improves stability of flow allocation.
Some other refactoring was also done, such as renaming port_map_entry
to irm_flow and hiding some internal structures of the registry.

The protobuf include directory was not being correctly handed to the
compiler when building. Now the include directory is added
project-wide. And the protobuf package is searched for only once.
