Every time the state is written out we may trigger third-party apps, so
let's be a bit more careful about writing this out unnecessarily.
|
|
|
|
We only keep the addresses that we added ourselves in link->addresses, and
introduce a new set link->addresses_foreign to keep addresses of unknown
origin.
Only functional change is that "foreign" addresses no longer prevent a link
from entering "configured" state.
|
|
These functions are almost entirely the same, so avoid duplication.
|
|
We were considering a link configured whilst its IPv6 addresses were still
tentative.
Fixes issue #650.

networkd/libsystemd-network: collection of trivial patches v2
|
|
With the previous description it wasn't clear that the
kernel default is being described.
Add link to kernel docs.
|
|
Checks that a given address is not tentative nor deprecated.
|
|
No need to expose these functions, but rather call them from address_{add,drop}.
|
|
We need to be able to look these things up quickly as we will be updating them
continuously and there can in principle be many of them.

Rename new_dynamic() to simply _new() and reuse that from new_static().

fixes Coverity #1317207

The DHCP variable in the [Network] section of the network configuration
file moves the link to the configured state according to the following:
DHCP=yes Link is configured when either DHCPv4 or DHCPv6 succeed
DHCP=ipv4 Link is configured only when DHCPv4 succeeds
DHCP=ipv6 Link is configured only when DHCPv6 succeeds
DHCP=no Neither DHCPv4 or DHCPv6 is attempted
Reported by Martin Pitt.
Fixes https://github.com/systemd/systemd/issues/1368

DHCPv6 suspend fixes
|
|
Wait until DHCPv6 has acquired an address before announcing the link
to be configured. Log the DHCPv6 lease lost event.
|
|
This causes the kernel to accept router advertisments even if
ip forwarding is enabled for this interface.
This fixes #1340.

Currently, sd-lldp.h exports "UPDATE_INFO".. and defines it to a magic
constant '10'. This is completely bogus, so fix it to follow our coding
standards:
- Prefix exported symbols by SD_LLDP_*
- Define a separate event-enum for event types
- Translate internal state to external event-types

This patch support to configure the ipv6 acceprt ra option.

Introduce a proper enum, and don't pass around string ids anymore. This
simplifies things quite a bit, and makes virtualization detection more
similar to architecture detection.
|
|
tree-wide: do not shadow the global var timezone
|
|
|
|
The constraints we place on the pool is that it is a contiguous
sequence of addresses in the same subnet as the server address, not
including the subnet nor broadcast addresses, but possibly including
the server address itself. If the server address is included in the
pool it is (obviously) reserved and not handed out to clients.
|
|
Don't restrict yourselves to 32 leases, simply manage the whole subnet by default.
|
|
Merge sd_dhcp_server_set_address() and sd_dhcp_server_set_lease_pool() into
sd_dhcp_server_configure_pool() as the behavior of the two former depends
on the order they are called in. The flexibility is not needed, so let's
just do this in one call.
|
|
We may not set it before checking it for null.
|
|
When handing out DHCP leases, try to propagate DNS/NTP server
information from "uplink". The "uplink" is automatically determined as
the network interface with the highest priority default route on it.
|
|
For now, this is very simple and IP addresses have to be configured
manually.
|
|
No functional changes, just moving definitions into separate header
files.
|
|
Previously we were setting the transient hostname again, rather than
resetting it.
|
|
|
|
|
|
When we make sd-dhcp public one day we really should not make
sd_dhcp_lease_save() and sd_dhcp_lease_load() public, since it's pretty
much only useful as internal utility for networkd itself.
|
|
This one is simply to add: encode the tzdata timezone in the DHCP
options and optionally make use of it.
|
|
Rename the enum, the lookup functions and the parser for LLMNRSupport so
the type can be reused for mDNS.
|
|
Append DNS and NTP data obtained via DHCPv6 when the Link is saved.
|
|
Use free_and_strdup() where appropriate and replace equivalent,
open-coded versions.
|
|
Some places invoked fflush() directly with their own manual error
checking, let's unify all that by using fflush_and_check().
This also unifies the general error paths of fflush()+rename() file
writers.
|
|
Justification is similar to BPDUGuard rename. "Positive" values
are easier. This is a rather uncommon option, so using a slightly
longer name should not be a problem, and may in fact may make it
easier to guess what the option does without reading the
documentation.
|
|
Rename to follow the follow the style of other options.
In general "positive" options are preferred to "negative" ones,
because they are easier to describe and easier for humans to
parse (c.f. the shortening on the man page entry).

Merge write_string_file(), write_string_file_no_create() and
write_string_file_atomic() into write_string_file() and provide a flags mask
that allows combinations of atomic writing, newline appending and automatic
file creation. Change all users accordingly.

- Make sure that the IPv6PrivacyExtensions=yes results in
prefer-temporary, not prefer-public.
- Introduce special enum value "kernel" to leave setting unset, similar
how we have it for the IP forwarding settings.
- Bring the enum values in sync with the the strings we parse for them,
to the level this makes sense (specifically, rename "disabled" to
"no", and "prefer-temporary" to "yes").
- Make sure we really set the value to to "no" by default, the way it is
already documented in the man page.
- Fix whitespace error.
- Make sure link_ipv6_privacy_extensions() actually returns the correct
enum type, rather than implicitly casting it to "bool".
- properly size formatting buffer for ipv6 sysctl value
- Don't complain if /proc/sys isn't writable
- Document that the enum follows the kernel's own values (0 = off, 1 =
prefer-public, 2 = prefer-temporary)
- Drop redundant negating of error code passed to log_syntax()
- Manpage fixes
This fixes a number of issues from PR #417
|
|
1) never bother with setting the flag for loopback devices
2) if we fail to write the flag due to EROFS (which is likely to happen
in containers where /proc/sys is read-only) or any other error, check
if the flag already has the right value. If so, don't complain.
Closes #469

This patch add support for ipv6 privacy extensions.
The variable /proc/sys/net/ipv6/conf/<if>/use_tempaddr
can be changed via the boolean
IPv6PrivacyExtensions=[yes/no/prefer-temporary]
When true enables privacy extensions, but prefer public addresses over
temporary addresses.
prefer-temporary prefers temporary adresses over public addresses.
Defaults to false.

If a link is attempted t obe enslaved by a netdev that has already failed, we
must fail immediately and not save the callback for later, as it will then
never get triggered.
