fscrypt can automatically unlock directories with the user's login
password. To do this it ships a PAM module which reads the user's
password and loads the respective keys into the user's kernel keyring.
Significant inspiration was taken from the ecryptfs implementation.
With Go 1.19 calls to setrlimit are required for lego to run.
While we could allow setrlimit alone, I think it is not unreasonable to
allow @resources in general.
Closes: #197513
Lego has a built-in mechanism for sleeping for a random amount
of time before renewing a certificate. In our environment this
is not only unnecessary (as our systemd timer takes care of it)
but also unwanted since it slows down the execution of the
systemd service encompassing it, thus also slowing down the
start up of any services its depending on.
Also added FixedRandomDelay to the timer for more predictability.
Fixes#190493
Check if an actual key file exists. This does not
completely cover the work accountHash does to ensure
that a new account is registered when account
related options are changed.
Fixes#191794
Lego threw a permission denied error binding to port 80.
AmbientCapabilities with CAP_NET_BIND_SERVICE was required.
Also added a test for this.
Before this change, the description for
security.wrappers.<name>.capabilities made it seem like you could just
string together the names of capabilities like this:
capabilities = "CAP_SETUID,CAP_SETGID";
In reality, each item in the list must be a full-on capability clause:
capabilities = "CAP_SETUID=ep,CAP_SETGID+i";
Summary: fix errors with example code in the manual that shows how to set up DNS-01 verification via the acme protocol, e.g. for those who want to get wildcard certificates from Let's Encrypt.
Fix syntax error in nix arrays (there should not be commas.)
Fix permissions on /var/lib/secrets so it can be read by bind daemon. Without this fix bind won't start.
Add the missing feature: put the generated secret into certs.secret
most of these are hidden because they're either part of a submodule that
doesn't have its type rendered (eg because the submodule type is used in
an either type) or because they are explicitly hidden. some of them are
merely hidden from nix-doc-munge by how their option is put together.
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
there are sufficiently few variable list around, and they are
sufficiently simple, that it doesn't seem helpful to add another
markdown extension for them. rendering differences are small, except in
the tor module: admonitions inside other blocks cannot be made to work
well with mistune (and likely most other markdown processors), so those
had to be shuffled a bit. we also lose paragraph breaks in the list
items due to how we have to render from markdown to docbook, but once we
remove docbook from the pipeline those paragraph breaks will be restored.
mostly no rendering changes. some lists (like simplelist) don't have an
exact translation to markdown, so we use a comma-separated list of
literals instead.
using regular strings works well for docbook because docbook is not as
whitespace-sensitive as markdown. markdown would render all of these as
code blocks when given the chance.
this renders the same in the manpage and a little more clearly in the
html manual. in the manpage there continues to be no distinction from
regular text, the html manual gets code-type markup (which was probably
the intention for most of these uses anyway).
now nix-doc-munge will not introduce whitespace changes when it replaces
manpage references with the MD equivalent.
no change to the manpage, changes to the HTML manual are whitespace only.
make (almost) all links appear on only a single line, with no
unnecessary whitespace, using double quotes for attributes. this lets us
automatically convert them to markdown easily.
the few remaining links are extremely long link in a gnome module, we'll
come back to those at a later date.
we can't embed syntactic annotations of this kind in markdown code
blocks without yet another extension. replaceable is rare enough to make
this not much worth it, so we'll go with «thing» instead. the module
system already uses this format for its placeholder names in attrsOf
paths.
markdown can't represent the difference without another extension and
both the html manual and the manpage render them the same, so keeping the
distinction is not very useful on its own. with the distinction removed
we can automatically convert many options that use <code> tags to markdown.
the manpage remains unchanged, html manual does not render
differently (but class names on code tags do change from "code" to "literal").
Instead of enabling the PAM modules based on config.krb5.enable,
introduce a new option to control the PAM modules specifically.
Users may want to turn on config.krb5.enable, to get a working Kerberos
client config with tools like kinit, while letting pam_sss or something
else handle Kerberos password lookups.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
