Subject: lsipc: fix semaphore USED counter
The code incorrectly counts only with the first item in the linked
list (due to a typo). It seems rather fragile to use "semds" and
"semdsp" as variable names in the same code ...
# lsipc -gs
Old:
KEY ID PERMS OWNER NSEMS RESOURCE DESCRIPTION LIMIT USED USE%
SEMMNI Number of semaphore identifiers 32000 3 0.01%
SEMMNS Total number of semaphores 1024000000 369 0.00%
SEMMSL Max semaphores per semaphore set. 32000 - -
SEMOPM Max number of operations per semop(2) 500 - -
SEMVMX Semaphore max value 32767 - -

Subject: libblkid: Check offset in LUKS2 header
LUKS2 binary header contains offset field that describes where
the header should be located.
If this offset is not correct, blkid should tread this header
as invalid.
This patch fixes problem when both swap and LUKS headers are present
(LUKS header was swapped out) and detected LUKS header is at a wrong
offset. As LUKS has higher priority, it confuses detection.

Subject: more: fix poll() use
The more(1) command utilizes signalfd() to monitor signals and reads
commands from the user via stderr (as stdin is typically used for
piping and not for user interaction).
However, the current more_poll() implementation ignores stderr. As a result,
more(1) waits on read(stderr) while completely ignoring signals. This issue
becomes evident when using commands like:
grep foo /path/file | more
In such cases, it's only possible to exit 'more' by pressing 'q';
CTRL+C does not work.
Changes:
- Refactor more_poll() code:
- Introduce an enum to access pfd[] items instead of using magical constants.
- Implement a while() loop to handle EAGAIN or POLLHUP.
- Ignore stdin after POLLHUP (indicating that the pipe's peer closed).
- Ensure stderr is also checked.
- Use return codes akin to classic poll().
Note: I have doubts regarding the usability of stdin in more_poll(),
as the function is primarily used to wait for user input (via stderr)
and to monitor signals. Nevertheless, it is retained for potential use
in detecting when the pipe's peer (or the entire session) has been
terminated (see commit 68e14d3d5f4116ad3aca0e392d008645ea90cf70).

Subject: more: make sure we have data on stderr
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
more(1) uses more_poll() to monitor data on stdin, stderr, and
signals. It is used before read_command(), but this function only
reads from stderr. Therefore, if any other non-stderr event occurs,
this function will wait on read(). In this case, more(1) will not
react to signals anymore. We need to ensure that more(1) only waits in
more_poll().
Try
 for x in {1..1000}; do echo "line $x"; done | more
to reproduce.
