Yu Watanabe 7f77917c0e sd-ipv4acd: update condition of address conflict 
See RFC 5227 section 2.1.1.

This introduces a callback which intend to a library user, e.g.
networkd, checks whether the sender hardware address is a MAC address of
the host's intrerface or not.

Franck Bui b25389d2bb login: XGI Z7/Z9 (XG20 core) graphic chip requires master-of-seat to be set 
This graphic chip doesn't have a DRM driver and fallback to vesa-framebuffer
driver.

Without this patch, users of such chip suddenly see their GUI broken without
any indication or reason of what happened (no error message). Hence this
regression is near to impossible to troubleshoot for end users.

Julia Kartseva 5587ce7f6c fragment: add ip protocol to SocketBind{Allow|Deny}= 
Add ip protocol token to SocketBind{Allow|Deny}= property parser.

Use parse_socket_bind_item helper.

Replace int32_t with int in cgroup item for socket-bind as it was
requested in [0].

Update tests.

Julia Kartseva 8bd095aa9a shared: add parser for SocketBind{Allow|Deny}= 
Parse address family, ip protocol and ports, any of them can be
optional. If neither is specified, a special value 'any' is expected.
Helper is placed in shared to be reused in both fragment and dbus.
Add unit tests with valid and invalid examples.

Julia Kartseva 159d68c3e0 shared: add ip_protocol_{from|to}_tcp_udp helpers 
Thin wrappers of ip_protocol_{from|to}_name targeting IPPROTO_TCP and
IPPROTO_UDP only.
Used to parse IP protocol configuration restricted only to TCP and UDP,
e.g. in SocketBind{Allow|Deny}= unit property.

These helpers are inspired by af_{from|to}_ipv4_ipv6 and potentially
extendable with other IP protocols if there is a use-case to expose
them.

Julia Kartseva 560d76243f bpf: add ip proto matching to socket-bind prog 
Lookup ip protocol in a socket address to allow or deny binding a socket
to the address.
Matching rule is extended with 'protocol' field. If its value is 0
(IPPROTO_IP) ip protocol comparison is omitted and matching is passed to
the next token which is ip ports.

Documentation is updated.

Alexander Tsoy 1f00a50c69 resolved: do not try to copy empty NSEC types bitmaps 
dns_resource_record_copy() assumes that NSEC types bitmap is non-empty
which results in a null pointer dereference inside bitmap_copy() in some
cases. Fix this by calling bitmap_copy() conditionally.

Raul Tambre d3a047b9d1 man: Don't link to a manpage that's within our documentation

Yu Watanabe 7bb9f0d014 sd-netlink: do not call lookup_nlmsg_type() for known generic netlink family 2021-06-27 03:58:30 +09:00
Yu Watanabe 0f97cfb9be sd-netlink: rename variables and functions for generic netlink 
`id` or `type` is ambiguous. Let's use `nlmsg_type`. Also, use `ret` for
function arguments to store results.

This also adds several assertions.
 2021-06-27 03:02:22 +09:00
Yu Watanabe eee15fff40 sd-netlink: do not trigger assertion by calling socket_broadcast_group_unref() with an arbitrary group number 
socket_broadcast_group_unref() is only called in netlink_slot_disconnect(),
so the assertion should not be triggered as the match slot was
successfully created.

But, we usually design `_ref/unref()` functions as they can be called
for any inputs. So, let's also follow the design rule here.
