A worthy concern on this regulation (low level): Internet Data Management Ordinance.

- Providing programs of traversing and circumventing the cross-border security gateway (aka. GFW) is forbidden;

- Users of such tools are not liable;

- Personal and family usage is out of this scope;

There's functions converting connection "deadlines" to/from other formats used elsewhere.

There's functions for reading & writing (as per the IETF spec) the options in the extended IPv6 header provided from the kernel via `struct cmsg`. Including routing information for e.g. ping/traceroute.

`bindresvport` iterates over privileged ports to `bind` a socket on an open one.

To aid network management "nss" & "nscp" sublibraries are wrapped to implement "net groups".

4/6?

And finally `getnameinfo`, after some validation, recomputes the hostname the given network address was parsed from, branching upon the socket type & flags. As well as the TCP or UDP port number. Ultimately calling the other functions I have or will described. The localhost address is cached, protected by a lock & double-checked `first` flag.

`__inet6_scopeid_pton` retrieves & serializes network interface indices.

As always I'm skipping over minor functions.

5/7?

Too few women at POPL 2022: rjlipton.wpcomstaging.com/2021

The low 11% representation on the program committee is especially striking in contrast to the significant historical contributions of women to programming languages (Kathleen Booth, Cicely Popplewell, Grace Hopper, Jean Sammet, Mary Hawes, Gertrude Tierney, and Barbara Liskov among them).

According to the same post, the major theoretical computer science conferences are only slightly better.

`inet_makeaddr` merges a network address & host address into the space of a single structure, determining how far to shift the network address based on which "class" it is in before OR'ing the two together. This code can be overriden by platform specific code.

Fully platform-specific stubs include:

* `setsourcefilter` & `setipv4sourcefilter`
* `if_nametoindex`, `if_indextoname`, `if_freenameindex`, & `if_nameindex`
* `getifaddrs` & `freeifaddrs`

6/6 Fin for today!

Testing the latest PinePhone Pro Manjaro Phosh image and it's looking very nice indeed. To give you an idea of speed i'm running it off of an sdcard just now but get this. Firefox opens in just 4 seconds ! Next stop is to test Plasma Mobile too. 😉 #Linux #Mobile
