Because of how we output lines in the loop above, if we leave that loop
when the last line was not the same in both files, then either
`file1_line` or `file2_line` has not been output yet.
`process_remaining()` does not print that line either, since it
immediately reads a new line. So, output the previously-missing line
before we call that. :^)
Each GenericInterruptHandler now tracks the number of calls that each
CPU has serviced.
This takes care of a FIXME in the /sys/kernel/interrupts generator.
Also, the lsirq command line tool now displays per-CPU call counts.
These lambdas were marked mutable as they captured a Ptr wrapper
class by value, which then only returned const-qualified references
to the value they point from the previous const pointer operators.
Nothing is actually mutating in the lambdas state here, and now
that the Ptr operators don't add extra const qualifiers these
can be removed.
This happens in two ways:
1. LibCore now has two new methods for creating Jails and attaching
processes to a Jail.
2. We introduce 3 new utilities - lsjails, jail-create and jails-attach,
which list jails, create jails and attach processes to a Jail,
respectively.
We previously had a lot of duplication (and mismatched settings) around
whether a target was "special" or not, although the only special thing
about it was that its name was a reserved keyword and therefore had to
be renamed later.
Fix that by mostly consolidating the different configuration paths and
then purging all duplicated linking libraries from the bottom of the
file.
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
Even though the toolchain implicitly links against -lc, it does not know
where it should get LibC from except for the sysroot. In the case of
Clang this causes it to pick up the LibC stub instead, which might be
slightly outdated and feature missing symbols.
This is currently not an issue that manifests because we pass through
the dependency on LibC and other libraries by accident, which causes
CMake to link against the LibC target (instead of just the library),
and thus points the linker at the build output directory.
Since we are looking to fix that in the upcoming commits, let's make
sure that everything will still be able to find the proper LibC first.
This allows running `ntpquery --help` in environments that do not have
the LookupServer service running, e.g. when generating man pages. The
same was done for netstat in commit 7fba413.
1. Don't use the sv literal as this bypasses CheckedFormatString.
2. Don't use the content of a file as the format string. If the file
contains "{}", the program will crash.
This adds the `nologin` application to the system. This application
will look for `/etc/nologin`. If it is present, it will display the
message in the file. Otherwise, it will display an error about the
current account being unavailable.
