package netchannel

v2.1.2 (2022-11-10)

• netback: go to closed state before removing vif from xenstore (@palainp, #105, addresses mirage/qubes-mirage-firewall#157)

v2.1.1 (2022-03-14)

• Do not Lwt.catch on the listen callback (@hannesm, @dinosaure, #103)

v2.1.0 (2022-02-01)

v1.11.0 (2019-05-05)

• Fix MAC address for netback devices (@talex5, #87). This changes the CONFIGURATION signature to provide both read_frontend_mac and read_backend_mac, and changes the XenStore implementation to return fe:ff:ff:ff:ff:ff for backends.

v1.10.2 (2019-04-01)

• Use the new grant API provided by mirage-xen (@talex5 and @yomimono, #85).

• Use lwt-dllist to remove deprecated Lwt_sequence (@avsm)

v1.8.1 (2019-01-07):

• require OCaml 4.03, remove "result" dependency (#77, from @hannesm)

• require ipaddr 3.0 (#79, from @hannesm)

1.8.0 (2017-12-14):

• Support client-initiated shutdown (#67, from @talex5)

• Improve shared ring handling between Netback and Netfront (#68, from @talex5)

• Fix a number of build errors and improve documentation (various, from @djs55 and @talex5)

1.7.1 (2016-06-16):

• Switch to jbuilder

• Add topkg

• Split into mirage-net-xen and netchannel

• Add dependency on io-page-xen

1.7.0 (2017-01-24):

• Build against MirageOS version 3, and drop support for previous versions.

• Log exceptions from the listen callback.

• Use Cstruct.hexdump_pp to dump frames on error.

• Use the Logs library for logging.

• Use a monotonic counter for the RX id.

1.6.1 (2016-05-02):

• Generate a unique ID for each page shared with Xen for receiving data

1.6.0 (2016-04-09):

• Don't assume the first interface is meant when id can't be decoded

• Remove camlp4 dependency, add OCaml 4.02.ppx dependency

• Add simple xen-build Makefile target which tests via Docker

1.5.0 (2016-01-08):

• Generate a unique ID for each Netfront request. Before, we used the grant ref, but multiple requests may use the same ref. This could lead to pages being returned to the free pool before they had been read by netback.

• Add netback support, allowing mirage-net-xen to provide virtual network interfaces to other domains. This API is currently experimental.

• Add support for fragmented frames, including frames larger than one page.

• Use Cstruct.fillv instead of our own copy (which was incorrect, but the buggy path didn't get called unless the frame was fragmented, which we didn't support anyway).

• Use the offset field (previously we assumed it was always zero).

• listen now starts and returns the polling thread. Before, it returned a dummy thread that never resolved. This means that errors in the listen thread should now be reported.

• Errors in the user function passed to listen are now handled by Lwt.async (however that is configured). Before, we always printed the exception and then continued.

• Don't discard frames sent before listen is called.

• Split Shared_page_pool out into its own module.

• Fixed some compiler warnings.

• Require shared-memory-ring >= 1.1.1 (#25).

• Require io-page >= 1.5.0 for page_size (#21).

1.4.1 (2015-03-14):

• Wait for the backend network device to enter the Connected state before transmitting packets. This fixes a race condition in a fast-booting unikernel that caused the first packet to be lost (#20, #23).

1.4.0 (2015-03-07):

• Add explicit connect function to interface (#19).

1.3.0 (2015-01-24):

• When waiting for space in the transmit queue, we would sometimes fail to notice when space became available. (#15)

• Copy out-bound data into pre-shared pages for performance, security and simplicity. (#17)

• Use a centrally sourced Travis file and test OCaml 4.02+ as well.

1.2.0 (2014-12-17):

• Add profiling tracepoints and labels (#13). Introduces a dependency on mirage-profile.

• New opam file present in source repository for OPAM 1.2 workflow.

1.1.3 (2014-08-08):

• Revert the serialization in 1.1.2 as Xen/ARM (4.5 and backport to 4.4) has been fixed to support granting the same page multiple times. Backport is in https://github.com/mirage/xen-arm-builder.

1.1.2 (2014-07-23):

• Wait for packets to be processed by the backend before returning from a writev call. Without this, the caller has no way to know when it's safe to reuse the buffer (#11).

1.1.1 (2014-05-27):

• Do not send oversized frames to the backend Netfront (#9 from Edwin Torok).

1.1.0 (2014-02-01):

• Depend on the unified io-page library instead of io-page-xen.

• Depend on new xen-event and xen-grant packages.

0.9.0 (2013-12-10):

• Add Travis CI scripts.

• Adapt to V1.NETWORK from mirage-types-0.5.0.

• Initial release based on mirage-platform-0.9.8 Netif.
