2024-04-30ctl: When setting Sa bits, other bits must remain set to '1'tnt/workSylvain Munaut1-5/+8
Some of the other bits will be used 'as-is'. For instance the bit 0 (MSB) will be copied from this if operating in nocrc4 mode. Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Change-Id: Id482c6a114e7bf051d157e81038f015e9d26fa99

The client may register a callback function to receive events. Because there is no relation between the connected client and the interface, all events are broadcasted to all clients that are connected to the server. Change-Id: I5ee3268f8349b611c3cf3fa0572dc5eab280ab2e

2024-01-19Add option to automatically reset RIFO on underrun/overflowAndreas Eversberg9-11/+51
Whenever the RIFO buffer fill drifts away from its target, it can be automatically reset and filled to the initial prefill_frame_count value. The average fill is measured over several seconds. A given deviation in percent of the prefill_frame_count is used to trigger that reset. If the deviation is not set (0), this feature is deactivated. There are two reasons for this to happen: The GPS clock is missing, so the receiving interface is not in sync with the transmitting interface. The delay changes significantly, due to congestion on the path between both peers. (poor internet connection) Change-Id: Id7ccbfbdb288990c01f185dec79a1022a68b4748
2023-12-17usb: Deal with truncated ISO IN transfersHarald Welte3-0/+29
It seems that in some circumstances, an ISO IN transfer can be truncated by the bus / host. In such situation we'd currently pass a non-modulo-32 length to the mux_demux (deframer) code, and it ASSERTs on that. Let's try to handle this more gracefully by substituting random garbage and letting higher layers deal with massive bit errors. Related: OS#5490 Change-Id: Ic453325b93b0e12727625a1495a948d96df4b542

2023-05-02proto_clnt: use osmo_fd_close to close the socket on connection lossPhilipp Maier1-2/+1
When the socket is closed due to a connection loss, we currently use close(). This is not enough since this will not remove the file descriptor from the select loop. Let's use osmo_fd_close. Related: OS#5983 Change-Id: I702b944baf2ebbcc84b6a211e245a4a41627bde6
2023-04-20proto_clnt: close osmo-e1d control socket on connection lossPhilipp Maier1-1/+5
When osmo-e1d is terminated the socket file descriptor on the client side will get permanent POLLHUP events. This means that the registered callback gets called with flags OSMO_FD_READ but the received data will be of length zero. We must detect this situations and close the file descriptor on connection loss. Otherwise we would get called over and over again in an endless loop, resulting in 100% CPU usage.

2023-02-01DAHDI trunkdev supportHarald Welte13-12/+469
DAHDI trunkdev is a newly-introduced 'virtual trunk' character device which is used instead of a real hardware driver. This means that an application (such as osmo-e1d) can implement a virtual E1 trunk and receive and transmit E1 frame data which is exposed to DAHDI users just like the data from a real physical E1 span. In order to build DAHDI trunkdev support into osmo-e1d, you will need a special fork of dahdi containing the required support, currently the laforge/trunkdev branch of the following repository: https://gitea.osmocom.org/retronetworking/dahdi-linux Change-Id: Ib15a7313fcd63e1ed9f2f5b349df967bc4335ec2

2022-11-01ctl: Prevent clients from opening TS0Harald Welte1-1/+1

2022-11-01support for e1-tracer hardwareHarald Welte1-13/+45
Recent work on the e1-tracer firmware is introducing a set of USB descriptors (as configuration 2) that are mostly compatible to how osmo-e1d talks to icE1usb. The main difference is that there's only one ISO IN endpoint per USB interface, and no ISO OUT or ISU FB endpoints. So we introduce some minor adjustments here to accommodate that.

2022-10-12usb: Claim and set interface alt-setting only for used linesSylvain Munaut1-15/+16
If a line is not auto-created, there is no point on claiming the matching interface and even less point setting the alt setting that will try to use USB isoc bandwith. With this you can no use only line 1 and not line 0 of a ice1usb for instance. While previously it would still "enable" line 0 and then line 1 would fail because on BW issues most of the case.

As soon as an OCTOI connection gets into ACTIVE state, send a ECHO_REQ every 10s and compute the RTT at the time of receiving the response. Contrary to the initial idea, the stat item contains the RTT (round trip time) measured in micro-seconds. Changing this is not a problem as so far the RTT was always reported as '0', and 0ms == 0us.
