For now this only exposes the domain name (DHCP Option 15), and not
the search string (DHCP Option 119), which will be implemented in
a follow-up patch.
If "machinectl poweroff" or "machinectl reboot" is used on a
systemd-nspawn container started with --keep-unit and --register, it
should *only* send the appropriate signal to the leader PID (i.e. the
container's systemd process). It shouldn't fall through to
manager_kill_unit() to also send the signal to the unit. The latter
ends up killing systemd-nspawn, which takes down the container
prematurely.
This reverts commit 9528592ff8.
Apparently TFO is actually the default at least for the server side now.
Also the setsockopt doesn't actually take a bool, but a qlen integer.
TCP Fast Open (TFO) speeds up the opening of successiveTCP)
connections between two endpoints.It works by using a TFO cookie
in the initial SYN packet to authenticate a previously connected
client. It starts sending data to the client before the receipt
of the final ACK packet of the three way handshake is received,
skipping a round trip and lowering the latency in the start of
transmission of data.
This patch adds support for TCP TCP_NODELAY socket option. This can be
configured via NoDelay conf parameter. TCP Nagle's algorithm works by
combining a number of small outgoing messages, and sending them all at
once. This controls the TCP_NODELAY socket option.
This is not certain to be likely.
Lennart says: a frequent usecase is invoking some function regularly in intervals
in such a case every single iteration we'll have to rearm
THis was accidentally broken, as we truned off LLMNR far to frequently,
where we only wanted to turn off LLMNr on IPV6 on kernels lacking
support for it.
On receiving a message, "kernel_seqnum" is set to "serial + 1". So
subtracting 1 will cause messages like "Missed 0 kernel messages",
which should be "Missed 1 kernel messages".
switch-root would only mkdir the parents of the mount move directories.
With this patch, the mount move target directory is created to make
switch-root to an empty root directory work.
i is being used incorrectly. It is used to refer to the number of
indexes calculated so far (out of k). However, it is also incremented
when a new hash key is being used. This means that the results are
inconsistent with the desired behavior described in PORTING-DBUS1
document.
The expected result is that for the default values of m and k (512, 8)
the 1st hash key should produce 4 indexes. The second hash key is used
for the next 4 and overall 8 indexes into m are calculated.
The current behavior results in 6 indexes being calculated, 4 coming
from hash key 1 and 2 others from hash key 5.
It is useful to color in the admin state both to easily spot failed links, but also to quickly
distinguish between links that are fully configured and in degraded mode (only IPv4LL) or in
degraded mode and still waiting for DHCP.
