shmat() requires the CAP_IPC_OWNER capability. When running test-seccomp
in environments with root + CAP_SYS_ADMIN, but not CAP_IPC_OWNER,
memory_deny_write_execute_shmat would fail. This fixes it.
kernel's 'make install' invokes install.sh which calls /sbin/install-kernel.
Thus we are invoked as e.g.
/sbin/installkernel 5.18.0 arch/x86/boot/bzImage System.map /boot
The last two arguments would be passed as "initrds".
Before , we would just quitely ignore
/boot, because it doesn't pass the 'test -f' test, and possibly try to do
something with System.map. 742561efbe tightened
the check, so we now throw an error.
It seems that the correct thing is to ignore those two arguments, because
our plugin syntax has no notion of System.map. And the installation directory
we can figure out ourselves better. Effectively, this makes things behave
like before, but less by accident.
Fixes#23490.
When closing a loop device, the kernel will asynchronously remove
the probed partitions. This can lead to race conditions where we
try to reuse a partition device that still needs to be removed by
the kernel. To avoid such issues, let's explicitly try to remove
any partitions using BLKPG_DEL_PARTITION when we're done with an
image.
To make sure we don't try to remove partitions when we want them
to remain (e.g. systemd-dissect --mount), we add
dissected_image_relinquish() in a similar vein to loop_device_relinquish()
and decrypted_image_relinquish().
Let the table span more than the default content width,
if the table contains alot of data (controlled by width: auto)
(720px is very good for continuous text, but too narrow for tables).
The container class is therefore adapted to put the
width restriction on the elements itself, allowing for
exceptions for individual elements like <table> and
<h1> (which used an offset margin before and is now
streamlined to use a max-width as well).
Also add a striped background to ease reading rows
and allow for horizontal mobile scrolling without
overflowing the entire document, only the table itself.
