Fixes#11600.
The code was effectively doing:
json_build(..., ({ char **_x = ((char**) ((const char*[]) {"one", "two", "three", "four", NULL })); _x; }));
but there was no guarantee that the storage for the array that _x points to
survives pass the end of the block. Essentially, STRV_MAKE cannot be used
inline inside of a block like this.
The GNU gold linker uses the section name `.rela.dyn` instead of
`.rela` for containing the relocation information. If this section
is not copied systemd-boot can crash.
Efitools started using wildcard section copies in their commit
b98d381b, and these wildcard sections are the only difference between
systemd-boot's section copy list and theirs. This patch add the
wildcard section `.rel*` to our objcopy, as it should include all
other wildcards assuming a recent GNU objcopy. Redundant arguments
for sections that would be matched by this wildcard are removed.
This patch has been tested on EDK II UEFI v2.70 Firmware on QEMU, and
Lenovo 0.5120 UEFI 2.40 Firmware on bare metal.
Fixes: #11541
It should make it easier to tweak them without having access to
SemaphoreCI itself (I'm glad I'm an admin there now but it shouldn't
be necessary to be an admin to add a couple of kludges :-)). More
importantly, changes to the settings will go through review and
be tested before they're applied globally potentially breaking
Semaphore as it happened two days ago.
I'll point Semaphore CI to these scripts once the PR is merged.
Creating a pipe with O_NONBLOCK causes both the read and the write end to
be marked as non-blocking.
The "write" end is passed to the kernel autofs module, and it does not
expect a non-blocking pipe. If it gets -EAGAIN when trying to write
(which is unlikely, but not completely impossible), it will close the
write end of the pipe, which leads to unexpected errors.
So change the code to only set O_NONBLOCK on the "read" end of the
pipe. This is the only end that systemd interacts with, so the only end
it should be configuring.
When there is bad link in the network the carrier goes up/down.
This makes networkd stops all the clients and drop config.
But if the remote router/dhcpserver running a prevention
of DHCP Starvation attack or DHCP Flood attack it does not allow
networkd to take a DHCP lease resulting failure in configuration.
This patch allows to keep the client running and keep the conf
also for this scenario.
