Rusty Russell	32c7c133f4	common/sphinx: make onionpacket.routinginfo a dynamic member. Still asserts that it's the standard size, but makes it a dynamic member. For simpliciy, changes the parse_onionpacket API (it must be a tal object now, so we might as well allocate it here to catch all the callers).

Rusty Russell	3776af4a35	common/sphinx: make TOTAL_PACKET_SIZE a macro. This paves the way for using it on different-sized onions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago
Rusty Russell	dc83e64003	tools/generate-wire: don't use void * pointers for tlv fromwire. And fix up the one place which got it wrong. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago
Rusty Russell	ca2bd98082	unittest: use common_setup / common_shutdown almost everywhere. Avoids much cut & paste. Some tests don't need any of it, but most want at least some of this infrastructure. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago
Rusty Russell	a8177e9013	Makefile: make check-includes check all the non-generated files. Note that check-whitespace and check-bolt already do this, so we can eliminate redundant lines in common/Makefile and bitcoin/Makefile. We also include the plugin headers in ALL_C_HEADERS so they get checked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	4 years ago
Rusty Russell	b0c9059602	tools/generate-wire: no more lonely messages! When we have only a single member in a TLV (e.g. an optional u64), wrapping it in a struct is awkward. This changes it to directly access those fields. This is not only more elegant (60 fewer lines), it would also be more cache friendly. That's right: cache hot singles!

Rusty Russell	23f3a3c840	devtools/blindedpath: implement scid support. This is what we expect in an enctlv used for htlcs. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	5 years ago
Rusty Russell	3b4a06f52b	common: generalize ecdh function. common/onion is going to need to use this for the case where it finds a blinding seed inside the TLV. But how it does ecdh is daemon-specific. We already had this problem for devtools/gossipwith, which supplied a special hsm_do_ecdh(). This just makes it more general. So we create a generic ecdh() interface, with a specific implementation which subdaemons and lightningd can use. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	5 years ago
Rusty Russell	91251b1870	common: add blinding helpers. We'll want this once we add blinded HTLCs. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	5 years ago
Rusty Russell	fcc68b9b06	devtools/blindedpath: add --simple-output for use from python. Normal output is suitable for feeding to devtools/onion, but for python tests we want something simpler. Ideally, we'd simply generate blinded paths in pyln. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	5 years ago
