Lennart Poettering 76875ba9cb capability-util: use UINT32_MAX as shortcut where appropriatea 2023-02-20 16:49:46 +01:00
Lennart Poettering 3b3ebabfa6 capability-util: add macro for largest cap we're willing to accept 
Let's hide the hard to grasp 62 behind a name.
 2023-02-20 16:49:45 +01:00
Lennart Poettering 3fd5190b5e capability-util: add CAP_MASK_ALL + CAP_MASK_UNSET macros 
We should be more careful with distinguishing the cases "all bits set in
caps mask" from "cap mask invalid". We so far mostly used UINT64_MAX for
both, which is not correct though (as it would mean
AmbientCapabilities=~0 followed by AmbientCapabilities=0) would result
in capability 63 to be set (which we don't really allow, since that
means unset).
 2023-02-20 16:49:45 +01:00
Lennart Poettering 6c5fff017e cap-list: make sure never to accidentally return more than 63 caps 
The rest of our codebase stores caps masks in a uint64_t, and also
assumes UINT64_MAX was a suitable value for "unset mask". Hence refuse
any caps outside of 0…62.

(right now the kernel knows 40 caps, hence 22 more to go before we have
to reconsider our life's choices.)

Lennart Poettering ebb93f3ccf cap-list: rework capability_set_to_string() 
Let's use strextend_with_separator() and CAPABILITY_TO_STRING().
 2023-02-20 16:49:45 +01:00
Lennart Poettering c52c4d6974 cap-list: add CAPABILITY_TO_STRING() macro using compound initialization to allocate fallback buffer 
Let's add a helper that can return a numeric string in case we don't
recognize a name for a capability.
 2023-02-20 16:27:26 +01:00
Lennart Poettering d0e67c69ba cap-list: refuse parsing numeric capability 63 
We refuse it otherwise currently, simply because we cannot store it in a
uint64_t caps mask value anymore while retaining the ability to use
UINT64_MAX as "unset" marker.

The check actually was in place already, just one off.
 2023-02-20 16:13:49 +01:00
Lennart Poettering 3f444e94f5 cap-list: modernize capability_set_from_string() a bit 
Make return parameter optional. And return whether there were any caps
we didn't recognize via 0/1 return value.
 2023-02-20 16:13:49 +01:00
Lennart Poettering 8142d73574 cap-list: rename capability_set_to_string_alloc() → capability_set_to_string() 
We typically don't use the _alloc() suffix anymore for anything, hence
drop it here too.

Yu Watanabe 135e5a201a udev-node: make stack_directory_read_one() accept NULL for devnode 
No functional change, as currently the function is always called with
non-NULL argument. Just a preparation for #26048 or #25839.

Yu Watanabe c207a57227 udev-node: drop unnecessary initialization 
The priority of device node symlink can be negative. So the
initialization is confusing.

Fortunately, this changes no functionality, as we only compare the
priorities of symlinks only when we parsed at least one device node and
its priority.

Mike Yuan db4691961c journalctl: fix output when --lines is used with --grep 
Previously, we skip the entries before arg_lines
unconditionally, which doesn't behave correctly
when used with --grep. After this commit, when
a pattern is specified, we don't skip the entries
early, but rely on the count of the lines shown
to tell us when to stop. To achieve that we would
have to search backwards instead.

Fixes #25147

Lennart Poettering a2b052b29f mempool: rework mempool_cleanup() to only release freed tiles 
This substantially reworks mempool_cleanup() so that it releases pools
with all freed tiles only, but keeps all pools with still-allocated
tiles around.

This is more correct, as the previous implementation just released all
pools regardless if anything was still used or not. This would make
valgrind shut up but would just hide memory leaks altogether. Moreover
if called during regular runtime of a program would result in bad memory
accesses all over.

Hence, let's add a proper implementation and only trim pools we really
know are empty.

This way we can safely call these functions later, when under memory
pressure, at any time.

Lennart Poettering 4392b983b8 mempool: make mempool_free_tile() return NULL

Dan Streetman e8858f1104 tpm2: simplify tpm2_seal() blob creation 
TPM2 marshalling will never increase the total size, only possibly decrease.
There is no need for checking for insufficient size if the buffer size
is set to the sizeof both objects to be marshalled.
