s6-networking/src/stls, branch v2.4.0.0 UCSPI TCP implementation and other networking utilities http://git.skarnet.org/cgit/s6-networking/atom/src/stls?h=v2.4.0.0 2020-12-07T12:53:54Z Change -K semantics: timeout *during handshake*, not afterwards 2020-12-07T12:53:54Z Laurent Bercot ska-skaware@skarnet.org 2020-12-07T12:53:54Z urn:sha1:f7e676abdc799fcee5138807447b5e91ab05508f - the TLS tunnel itself should be transparent so it has no business shutting down the connection no matter how long the app takes - there's still an undetectable situation on some kernels where EOF doesn't get transmitted from the network, and the engine is in the handshake, and it can't do anything but wait forever. A timeout is useful here: dawg, your peer is never going to send any more data, you should just give up. - if the situation happens after the handshake, the *app* should have a timeout and die. The tunnel will follow suit. - libtls has a blocking tls_handshake() blackbox, we cannot give it a timeout. Too bad, use bearssl. stls client: prefer CAFILE, warn on CADIR use, because libtls is broken 2020-11-23T15:39:17Z Laurent Bercot ska-skaware@skarnet.org 2020-11-23T15:39:17Z urn:sha1:030ba53485e9b8a2793e1f1c9c8f62f8b8987e95 Fix more bugs; disable renegociation in bearssl client 2020-11-23T14:25:24Z Laurent Bercot ska-skaware@skarnet.org 2020-11-23T14:25:24Z urn:sha1:564631637bcd238b4c9aad5496aa9e049f948dd9 Fix a few bugs. sbearssl appears to be working. 2020-11-22T21:49:58Z Laurent Bercot ska-skaware@skarnet.org 2020-11-22T21:49:58Z urn:sha1:bae11b88357db72b19413cd05c62ac9242b9b597 Add SSL_PROTOCOL and SSL_CIPHER support, fix some bugs 2020-11-22T15:46:34Z Laurent Bercot ska-skaware@skarnet.org 2020-11-22T15:46:34Z urn:sha1:4fb917263ac30373cb3e5dfe3e207369eb238def Add documentation, fix tiny privdrop bug 2020-11-22T00:16:06Z Laurent Bercot ska-skaware@skarnet.org 2020-11-22T00:16:06Z urn:sha1:47cbbb1619ace4013856843ef8f7d68279c74faa Privs can only be dropped after reading key files. 2020-11-21T02:22:09Z Laurent Bercot ska-skaware@skarnet.org 2020-11-21T02:22:09Z urn:sha1:5c2880becc94141b8035b3488b6bd60696011308 Refactor tls code to support ucspi-tls 2020-11-20T23:24:29Z Laurent Bercot ska-skaware@skarnet.org 2020-11-20T23:24:29Z urn:sha1:5715c21a077ee1c2fe8957cb4adcea14fd2eda6b That includes: - new architecture: the tls binary is now a child of the app instead of the other way around - the sbearssl_run engine now takes a post-handshake callback. This allows s6-tlsc and s6-tlsd to only exec into the app when the handshake succeeds (which was already the case with libressl). - new binaries s6-tlsc-io and s6-tlsd-io encapsulate the crypto code; they init and run the engine, connecting to 4 already open fds (stdin/stdout = network, argv[1] and argv[2] = local) - s6-tlsc is now a simple wrapper around s6-tlsc-io - s6-tlsd is now a simple wrapper around s6-tlsd-io - new binary: s6-ucspitlsd, which is also a wrapper around s6-tlsd-io, but differently: the parent execs the app which should be ucspi-tls-aware, the child waits for a command from the parent and execs into s6-tlsd-io if it receives it. Moderately big hammer: force kill on s6-tlsd when it has nothing to write to the network 2017-08-28T21:10:03Z Laurent Bercot ska-skaware@skarnet.org 2017-08-28T21:10:03Z urn:sha1:5691bc64df8444cfbebe7a97480f49f79497b19b Revert big hammer. Data still needs to be flushed to the network even when the local app dies. 2017-08-28T20:30:00Z Laurent Bercot ska-skaware@skarnet.org 2017-08-28T20:30:00Z urn:sha1:d594db1b68d6a2c890d385087799dd8cdf6dc966
