- Kore now only supports OpenSSL 1.1.1 and LibreSSL 3.x.
- Revise the default TLS ciphersuites.
- Kore now carries ffdhe4096.pem and installs it under PREFIX/share/kore.
- Kore its tls_dhparam config setting defaults to the path mentioned above
so you no longer have to set it.
Allows building Kore with several different component versions.
Eg:
$ ./build-kore.sh 1.1.1h 3.9.0 7.72.0 1.41.0
Will build Kore with OpenSSL 1.1.1h, Python 3.9.0, Curl 7.72.0
and nghttp2 (for curl) 1.41.0
- Fix the curl-extract-opt.sh generation script to work on newer
curl releases as the header changed slightly.
- Use the correct handles when calling curl_easy_setopt() inside
of our setopt functions exported via Python.
- Add a curl.setbody() method, allowing a body to be sent to be set.
(eg when sending mail via SMTP).
- Regen of our python_curlopt.h from 7.71.1
Kore already exposed parts of this via the kore.httpclient() method but
this commit takes it a bit further and exposes the libcurl interface
completely (including the setopt options).
tldr:
handle = kore.curl("ftp://ftp.eu.openbsd.org/pub/OpenBSD/README")
handle.setopt(kore.CURLOPT_TIMEOUT, 5)
data = await handle.run()
print("%s" % data.decode())
Use the syscall.h.in files from musl and generate the syscall maps
from there. Now we have proper support for x86_64, i386, arm and aarch64
to have syscall maps.
A new hook in the koreapp class is called right before seccomp
is enabled. This hook receives a Kore seccomp object which has
the following methods:
seccomp.allow("syscall")
seccomp.allow_arg("syscall", arg, value)
seccomp.allow_flag("syscall", arg, flag)
seccomp.allow_mask("syscall", arg, mask)
seccomp.deny("syscall")
seccomp.deny_arg("syscall", arg, value, errno=EACCES)
seccomp.deny_flag("syscall", arg, flag, errno=EACCES)
seccomp.deny_mask("syscall", arg, mask, errno=EACCES)
This allows you to finetune the seccomp filters for your application
from inside your koreapp.
With this commit all Kore processes (minus the parent) are running
under seccomp.
The worker processes get the bare minimum allowed syscalls while each module
like curl, pgsql, etc will add their own filters to allow what they require.
New API functions:
int kore_seccomp_filter(const char *name, void *filter, size_t len);
Adds a filter into the seccomp system (must be called before
seccomp is enabled).
New helpful macro:
define KORE_SYSCALL_ALLOW(name)
Allow the syscall with a given name, should be used in
a sock_filter data structure.
New hooks:
void kore_seccomp_hook(void);
Called before seccomp is enabled, allows developers to add their
own BPF filters into seccomp.
