Checking the range of c|0x60 incorrectly classifies many characters
as alphabetic (digits, control characters 0x01-0x20, and punctuation
characters '!'-':'). This prevents tmparse from parsing dates with
a timezone bounded by those characters (for example, "12:11:56 (PDT)").
Instead, just reuse the isalpha macro provided by ctype.h.
When diffing non-regular files, like /dev/null,
pipes, and similar, diff will generate a temp
file to diff against. This is the right thing
to do, but the temp file leaks into the diff.
This patch retains the original file name all
the way through to diff output.
This code is checking the return of devwalk for
a walk resulting in a clone of an open pipe file. However,
devclone ensures that the chan we are cloning is not
currently open.
This is mostly a copy of port/usbxhci.c with PCIWADDR() replaced
by PADDR() and the pci specific code stripped out.
This could be refactored at a later time.
There is a gpio line for the main hub reset that needs to be
asserted and some power management functions that are currently
done by u-boot (using "usb start" command).
We will do these ourselfs once we have the infrastructure for
it in place.
The getserv function has remained mostly unchanged since
1ed. These checks are for handling string local ports
or lack thereof. This was used by datakit at the time,
where 'ports' were service strings. This made the default
datakit service 'login' when a connector did not give
a specific service. The checks for directory traversal also
seemed specifically to guard against a connector from providing
a malicious service string. With datakit gone all current protocols
use numerics as ports so these checks and defaults become uneeded.

Test(1) was fixed some time ago [1] to properly parse all of its
command line arguments. As such, we need to be more careful about
using test(1) with globbing patterns.

This is a work in progress port to the mntreform2 laptop.
Working so far:
- mmu (same as raspberry pi 3b+)
- arm generic timer
- gicv3
- uart1
- enet
With access to the uart, one can netboot this kernel in u-boot
using the following commands:
> dhcp
> bootm
devproc allows changing the noteid of another process
which opens a race condition in sysrfork(), when deciding
to inherit the noteid of "up" to the child and calling
pidalloc() later to take the reference, the noteid could
have been changed and the childs noteid could have been
freed already in the process.
this bug can only happen when one writes the /proc/n/noteid
file of a another process than your own that is in the
process of forking.
the noteid changing functionality of devproc seems questinable
and seems to be only used by ape's setpgrid() implementation.
Scrollbar was drawn using a wide dark gutter over a white background
whereas other applications (window, sam, ...) use a thinner scrollbar with an
inverse colorscheme.
This makes the scrollbar more consistent with other 9front applications.
When writing to a large variable in /env, we
spam 'Write error', in spite of the env var
working. This is new behavior, as of commit
b90036a062.
It produces a lot of scary, noisy warnings,
which are probably bogus.
