"port >= 0" is always true, because the port always gets filtered
through "htons" which returns "unsigned short", so we can just drop
the "else" branch here.
Anyway "announce 0" works fine with the Plan9 API, there is not need
for "announce *" here.
Despite the documentation, "bind *" is invalid and gives the error
"bad numeric port" in devip.c:setladdrport.
"bind 0" OTOH is actually supported fine in the Plan9 API and has the
right sematics.
-. decides where we chdir to before execing, we can't
sit where we are because our directory may not exist.
If not specified we go to '/'.
-s is used to source a rc script instead of execing cmd.
This is primarily to enable:
'#!/bin/auth/box -s'
Shebang line size is a bit tight(32), so we have this shorthand
to use rc along with setting up the required namespace components.
This specifically fixes
% man -P ktrans
We dont have font widths for kanji in our troff
font files, so we can use aux/mnihongo to render
the character using libdraw, and grab the bitmap from
there. It's not pretty, but aux/mnihongo exists so
lets at least use it.
This also updates /sys/man/1/ktrans to specify the
Jp font to comply with aux/mnihongo.
when writing to the nvme ssd, the screen can glitch out.
found this in linux lcdif driver (mxcfb) that appears to
resolve the issue.
the QoSc registers are all completely undocumented tho :-(
Some programs will strip trailing spaces from hunks;
in this case we want to treat the line as though it
came with a leading space.
This fixes applying some patches, such as
[PATCH] Permissions for child boards in /srv
A silly little patch, but some ptp devices (like the camera I own) use USB3 endpoints and subsequently require the data size of the payload to be 1024(-12 for metadata). This is reflected in libgphoto2's current ptp driver.
An attacker may use an infinite number of SPF referrals in his/her SPF
setting and can send an email to your mail server which would make
your SMTP server make a lot of DNS queries. By exploiting this
vulnerability, an attacker can block your SMTP queue, flood the
associated recursive resolver, or any DNS authoritative server.
According to RFC recommendations
(https://datatracker.ietf.org/doc/html/rfc7208#section-4.6), a few DNS
lookup limits exist that an SMTP server needs to maintain while
resolving an SPF record. That is, SPF implementations MUST limit the
total number of query-causing terms to 10 and the number of void
lookups to 2 to avoid unreasonable load on the DNS.

In run.c::assign(), assigning to $0 from $F, a field,
where F >= 2, produces an incoherent cell.
The assignment occurs in two steps, first the string value
and then the float. When the string value is assigned to $0,
setsval invalidates the fields. If FS hasn't changed, after
getfval rebuilds the fields, NF = 1 and F >= 2, therefore $F
is definitely uninitialized. The result is a float val of
0.0, producing a boolean false in the pattern expression.
Coercing a string comparison gives the expected result
because the incoherent cell has the correct string
value, which is not empty and evaluates to true.
when using records in BEGIN, we would read
from the field table before we read into it;
this ensures that the fields are an empty
string before we start touching their contents.
when reading a long line such as a dkim key in a
txt record, ndb calls Brdstr, which is limited
to the size of the buffer. This means we would
fail to parse the line from NDB, and bail out
early.
Increasing the buffer size allows us to read and
parse longer lines.
mdio interrupt command completion handling was broken,
as the interrupt handler would clear the mii status
register before mdiodone() sees it.
handle errors in miistatus() and miiane(), to not get
confused.
