2020-09-20make sure a given timeslot can only be opened once (by default)Harald Welte5-5/+37
Align the behavior of osmo-e1d with that of DAHDI: If a timeslot is opened once, it cannot be opened again by anyone until it is closed by the current owner. This way we'd have the same failure semantics in DAHDI vs. osmo-e1d, which is very useful in case of misconfiguration when osmo-bsc + osmo-mgw would "fight" over a timeslot. Add a osmo_e1dp_client_ts_open_force() function that allows to override and get back the original behavior. Closes: OS#4654 Change-Id: Ib25adf827ec41e74de15e0e4fdcfc9bcc9a32e58
2020-09-11e1-prbs-test: Add support for osmo-e1dHarald Welte2-14/+68
This allows e1-prbs-test to not only use DAHDI devices, but also osmo-e1d supported devices Change-Id: I0e88f2b056db931b0e442567efa9a8d270abb9f2
2020-09-11src/ctl.c: Log NOTICE messages whenever client send unexpected requestsHarald Welte1-5/+16

2020-09-01usb: Don't pass negative length values to e1_line_demux_in()Harald Welte1-0/+2
every so often, the USB transfer completes without data (due to "unlucky" time alignment between E1 and USB frame clock). Don't call the demuxer in that case. Otherwise the user is confused by error messages like <0001> intf_line.c:467 (I0:L0) IN ERROR: -4 Change-Id: Ia99f97c2cca44d15a83a54cebe884b343ec44f46
2020-07-22make RAW read buffer size configurable (instead of hard-coded 160)Harald Welte5-10/+20
When opening a timeslot, the client can now specify the (from application perspective) timeslot read buffer size. This breaks ABI, but then we're still at a point where only prototype hardware exists, so we can get away with it. Change-Id: I6d603778cce14c5d72fe5f54904905ea7e66d7ff
2020-07-22add comment about first byte of E1DP_MAGICHarald Welte1-0/+2

2020-07-22implement buffering to chunks in E1->application directionHarald Welte3-2/+66
Existing applications (such as those written for DAHDI) expect to be reading data in buffer/chunk sizes. For example OsmoNITB: It doesn't want to execute an expensive read/recv syscall to receive 11 bytes, if it needs at least 160 bytes. Change-Id: I807671bc6f2acaef740ce215b8d8abcb5dce2640
2020-07-20cosmetic: create HDLC specific sub-structure within e1_tsHarald Welte3-29/+31
This groups all HDLC-specific members together, in preparation of adding more fields for other modes. Change-Id: Ide0577c25836252862153b4f24da550bee013687
2020-07-15Add new E1DP_CMD_LINE_CONFIG for switching channelized/superchannelHarald Welte5-0/+122
This adds the related code to the server and client side of the CTL interface to switch a line between CHANNELIZED and SUPERCHANNEL. Change-Id: I765b5c3bc9e07b2353f8647e8260ff95df3727e6
2020-07-14actually implement the superchannel modeHarald Welte3-59/+172
In superchannel mode, all 31 TS are grouped together. There is no way to enable it yet, see next patch. Change-Id: Id340b1925471f427deb6cda7eb54e80dfc71faec
2020-07-14introduce concept of superchannel to data structuresHarald Welte4-6/+33
We treat the superchannel as an extra, separate timeslot. Initially I thought of simply re-using TS1, but keeping the superchannel separate ensures that it doesn't inherit any state (like half-sent HDLC frames) from another timeslot when we switch between the modes at runtime.

2020-07-12Fix HDLC-FCS transmit sideHarald Welte1-1/+1
If we are not able to read more packets from the user application, the recv/read call will return 0 and set errno = EAGAIN. In this situation we cannot bail out but still ask the HDLC code to generate output (sequences of flag octets). If we fail to do that, we will transmit all-ones pattern instaed of all-flag octets. Change-Id: Id3bc76f1956138dcd9cb7b499f7251cd94af1329
2020-07-11Use SOCK_STREAM sockets for E1_TS_MODE_RAWHarald Welte2-7/+15
SEQPACKET is great for preserving message boundaries on signaling channels that use HDLC. However, its semantics, particularly regarding truncation, are sub-optimal for RAW slots containing raw user bitstreams (typically TRAU frames or PCM audio data). So let's use SOCK_STREAM for RAW and keep SEQPACKET for HDLCFCS. Closes: OS#4663 Change-Id: I1767ceaa5d2a008db0009b8027667a71c0fdc0f1

2020-07-09usb.c: Fix error introducing Tx underflowsHarald Welte1-1/+1
In Change-Id I7d4d4ab39cb3e7e6a7eb8e738a367122eb3fbee2 I inroduced a bug that would cause e1_usb_xfer_out() to return four bytes too little, which in turn causes E1 Tx underflows to happen in the device firmware. Change-Id: I71675d4de781421286f0d1febedfdb1f7b523c38

2020-07-09migrate to proper allocated USB Product IDHarald Welte1-1/+1
The 0xe1e1 was a neat hack in the early days, but now 0x6145 has been allocated within the Openmoko USB VendorID. The current device firmware already uses the new ProductID, let's change it here, too. Change-Id: Iea6087ce02c931c796d9c9cae89cdf5b5e0b28c5

2020-06-30Add osmo-e1d-pipe utilityHarald Welte3-0/+219
This adds the 'osmo-e1d-pipe' utlility program, which can be used as a command-line client to open a given E1 timeslot and connect it to stdin/stdout. This in turn allows to rediect file input/output via the shell. Change-Id: Ib9d55af786c87e15465b8e73493680b35afb5913
2020-06-29Add virtual pair of E1 interfacesHarald Welte6-9/+232
The idea is to generate a pair of virtual E1 interfaces (each with identical number of lines), where each line A:n is connected to line B:n of the pair and vice-versa. This allows to test E1 using applications back to back against each other, without any physical E1 circuits in between. Change-Id: If42c959556b17d543762546eb45dd69d25f715f2
2020-06-29actually set the back-pointer from timeslot to lineHarald Welte1-0/+1
'struct e1_ts' always had a back-pointer to the line it is part of, but apparently this was never initialized so far. Change-Id: I5e6c8189bf5aa4af26d6cd6c6d288a149ed7fa66

2020-06-29Always log context (interface/line/timeslot) when availableHarald Welte3-12/+21

2020-06-29close timeslot socket if read or write returns negativeHarald Welte1-4/+23
If the user application has closed the timeslot socket, we will get error returns from read/write calls, which we must use to clean up the daemon-side state for this timeslot. Change-Id: I2e3e5010f36e916b4c8908af91447b3d3661123f

2020-06-29change list ordering for list of interfaces / linesHarald Welte1-4/+4
By using llist_add_tail(), we add new elements at the end of the list, rather than inserting at front. Among other things, this has the added benefit that when the VTY prints information on lines, they are printed in numerically ascending orrder (0,1,2, ...) and not the reverse.
