we have to protect the temporary buffer allocated by rwfield()
as rwreg() calls amlmapio() which might cause further aml code
execution causing gc() which frees it under us (as it is not
referenced from the interpreter state).
this fixes a panic on boot of a
Lenovo Thinkpad P17 Gen1 Professional Mobile Workstation
when a virtio device gets reset, we have to also reset the device
shadow indices: availableidx and usedidx. for extra safetly,
we also reset the buffer descriptor table addresses.
this is accomplished by adding a vioqreset(VIOQueue*) function
that brings the queue to its initial reset state.
this fixes non functional ethernet after reboot(8).
The new interface uses pci capability structures to locate the
registers in a rather fine granular way making it more complicated
as they can be located anywhere in any pci bar at any offset.
As far as i can see, qemu (6.0.50) never uses i/o bars in
non-legacy mode, so only mmio is implemented for now.
The previous virtio drivers implemented the legacy interface only
which uses i/o ports for all register accesses. This is still
the preferred method (and also qemu default) as it is easier to
emulate and most likely faster.
However, some vps providers like vultr force the legacy interface
to disabled with qemu -device option "disable-legacy=on" resulting
on a system without a disk and ethernet.
This used to be a internal function, but virtio
uses multiple structures with the same cap type
to indicate the location of various register
blocks in the pci bars so export it.
fn foo @{bar} is now equivalent to
fn foo {@{bar}}. As a side effect,
this disallows creating functions
named after keywords without first
quoting them.
We need a way to parse a rsa certificate request and return the public
key and subject names. The new function X509reqtoRSApub() works the
same way as X509toRSApub() but on a certificate request.
We also need to support certificates that are valid for multiple domain
names (as tlshand does not support certificate selection). For this
reason, a comma separated list is returned as the certificate subject,
making it symmetric to X509rsareq() handling.
A little helper is provided with this change (auth/x5092pub) that takes
a certificate (or a certificate request when -r flag is provided) and
outputs the RSA public key in plan 9 format appended with the subject
attribute.
git/export *almost* produces output that can be
emailed with upas using
git/export $commit | mail maintainer@site.com
but, the
From: commit-id date
line that git generates trips it up. Luckily,
'git am' doesn't seem to care much if that line
is missing, so we can simply omit it with no issue.
There are a number of alphabets in common use for base32
and base64 encoding, such as url-safe encodings.
This adds support for passing a function to encode into
arbitary alphabets.
Authsrv(6) used to be called auth(6) before
the fourth edition and was preprocessed by
eqn(6) before the third edition. The mkfile
was never updated to reflect the changes.

When resizing windows, vt would signal ssh by updating
the window size and sending an interrupt. Ssh reacted
by forwarding both the winch and an interrupt.
This change adds a WINCH generation counter so that
ssh can differentiate between resizes and interrupts.
If an interrupt comes in, and the WINCH generation
changes, then the interrupt is taken as signalling a
WINCH.
The change to "assignment not used" breaks symmetry with
"used and not set" and removes the reference to the
specific warning mentioned in /sys/doc/comp.ms.
Also, the patch was half-assed as that it left some typos
in like "used an not set", which this change also fixed.
We weren't correctly skipping the location operators
in codefree. This would mostly be work, but sometimes
you'd get unlucky and have one of the argmuents mismatch,
and that would lead to an invalid free.
This correctly skips the args in codefree.
Since we now store /dist/plan9front in git, the
initial assumption that the owner of the repo
is the person touching it is not always true.
This change gives us a better heuristic for the
file permissions we should have in the files we
copy around, basing it off of the permissions of
the .git directory.
When loading a file using ".", we could
end up with our line numbers thrown off
due to the mutation of lexline. Putting
lexline into the runq beside the file
that we're reading from causes it to get
pushed and popped correctly, so that we
no longer lose track of our location.
