      contrib/rpm: Provide list of units to %systemd_postun · 7d62f81e
      Till Maas authored
      %systemd_postun is meant to be run with arguments and Fedora Rawhide
      seems to enforce this now. Therefore provide the units there, too.

      build/meson: fix location of introspection files · ad9e5995
      Thomas Haller authored
      With glib < 2.51.3, gdbus-codegen does not understand "--output-directory" [1].
      Hence, the generated files are like
      
          "build/dbus-org.freedesktop.NetworkManager.Device.WifiP2P.xml"
      
      instead of
      
          "build/introspection/dbus-org.freedesktop.NetworkManager.Device.WifiP2P.xml"
      
      But gnome.gdbus_codegen() returns a path as if it would be inside
      "build/introspection". Hack around that, by patching the correct path
      otherwise. This is still ugly, because repeated "ninja -C build" calls
      will always try to rebuild this target (because the wrong file name
      is considered).
      
      See also [2].

      shared: build helper "libnm-libnm-core-{intern|aux}.la" library for libnm-core · af07ed01
      Thomas Haller authored
      "libnm-core" implements common functionality for "NetworkManager" and
      "libnm".
      
      Note that clients like "nmcli" cannot access the internal API provided
      by "libnm-core". So, if nmcli wants to do something that is also done by
      "libnm-core", , "libnm", or "NetworkManager", the code would have to be
      duplicated.
      
      Instead, such code can be in "libnm-libnm-core-{intern|aux}.la".
      Note that:
      
        0) "libnm-libnm-core-intern.la" is used by libnm-core itsself.
           On the other hand, "libnm-libnm-core-aux.la" is not used by
           libnm-core, but provides utilities on top of it.
      
        1) they both extend "libnm-core" with utlities that are not public
           API of libnm itself. Maybe part of the code should one day become
           public API of libnm. On the other hand, this is code for which
           we may not want to commit to a stable interface or which we
           don't want to provide as part of the API.
      
        2) "libnm-libnm-core-intern.la" is statically linked by "libnm-core"
           and thus directly available to "libnm" and "NetworkManager".
           On the other hand, "libnm-libnm-core-aux.la" may be used by "libnm"
           and "NetworkManager".
           Both libraries may be statically linked by libnm clients (like
           nmcli).
      
        3) it must only use glib, libnm-glib-aux.la, and the public API
           of libnm-core.
           This is important: it must not use "libnm-core/nm-core-internal.h"
           nor "libnm-core/nm-utils-private.h" so the static library is usable
           by nmcli which couldn't access these.
      
      Note that "shared/nm-meta-setting.c" is an entirely different case,
      because it behaves differently depending on whether linking against
      "libnm-core" or the client programs. As such, this file must be compiled
      twice.

      shared: move most of "shared/nm-utils" to "shared/nm-glib-aux" · 80db06f7
      Thomas Haller authored
      From the files under "shared/nm-utils" we build an internal library
      that provides glib-based helper utilities.
      
      Move the files of that basic library to a new subdirectory
      "shared/nm-glib-aux" and rename the helper library "libnm-core-base.la"
      to "libnm-glib-aux.la".
      
      Reasons:
      
       - the name "utils" is overused in our code-base. Everything's an
         "utils". Give this thing a more distinct name.
      
       - there were additional files under "shared/nm-utils", which are not
         part of this internal library "libnm-utils-base.la". All the files
         that are part of this library should be together in the same
         directory, but files that are not, should not be there.
      
       - the new name should better convey what this library is and what is isn't:
         it's a set of utilities and helper functions that extend glib with
         funcitonality that we commonly need.
      
      There are still some files left under "shared/nm-utils". They have less
      a unifying propose to be in their own directory, so I leave them there
      for now. But at least they are separate from "shared/nm-glib-aux",
      which has a very clear purpose.

      shared: move udev helper to separate directory "shared/nm-udev-aux" · 2973d682
      Thomas Haller authored
      We built (among others) two libraries from the sources in "shared/nm-utils":
      "libnm-utils-base.la" and "libnm-utils-udev.la".
      
      It's confusing. Instead use directories so there is a direct
      correspondence between these internal libraries and the source files.

      shared: split C-only helper "shared/nm-std-aux" utils out of "shared/nm-utils" · b434b9ec
      Thomas Haller authored
      "shared/nm-utils" contains general purpose utility functions that only
      depend on glib (and extend glib with some helper functions).
      
      We will also add code that does not use glib, hence it would be good
      if the part of "shared/nm-utils" that does not depend on glib, could be
      used by these future projects.
      
      Also, we use the term "utils" everywhere. While that covers the purpose
      and content well, having everything called "nm-something-utils" is not
      great. Instead, call this "nm-std-aux", inspired by "c-util/c-stdaux".

      cli: use "escaped-tokens" style for splitting "vlan.xgress-priority-map" list · 7f01da91
      Thomas Haller authored
      There should be little difference here, because the priority list is
      (and was) never serialized with special characters like backslashes or
      delimiters that require escaping.
      
      Likewise, no working code actually tried to set such characters.
      
      Still, drop the plain VALUE_STRSPLIT_MODE_STRIPPED and use
      VALUE_STRSPLIT_MODE_ESCAPED_TOKENS_WITH_SPACES instead. We should have
      a small set of modes that we use for splitting strings.

      cli: cleanup _get_fcn_vlan_xgress_priority_map() · bbfd3668
      Thomas Haller authored
      - merge the pointless helper function vlan_priorities_to_string()
        into the only caller _get_fcn_vlan_xgress_priority_map().
      
      - minor cleanups, like setting out-is-default if num==0, not
        based on whether we have a non-empty string. There is not difference
        in practice, because nm_setting_vlan_get_priority() never fails.
        Hence they are identical. But nm_setting_vlan_get_priority() has
        an API that allows it to fail, so we should declare the default
        depending on the number of vlan priorities.
      
      - don't allocate the temporary GString instance if we won't need it.
      
      - only append the delimiter if needed, and not truncate it afterwards.
        It might have even worse performance this way, but it feels more
        correct to me.
      
      - also cache the result of nm_setting_vlan_get_num_priorities().
        NMSettingVlan's implementation is horrible and uses a GSList to
        track the list of priorities. This makes it relatively expensive
        to call get-num-priorities repeatedly (and pointless).

      cli: refactor multilist property handling of "match.interface-names" · 6093f493
      Thomas Haller authored
      We had %VALUE_STRSPLIT_MODE_MULTILIST_WITH_ESCAPE, which was used
      by "match.interface-names". This uses nm_utils_strsplit_set_full()
      with %NM_UTILS_STRSPLIT_SET_FLAGS_ALLOW_ESCAPING and
      _nm_utils_unescape_plain().
      
      We want eventually to use nm_utils_escaped_tokens_split() everywhere.
      
      We already have %VALUE_STRSPLIT_MODE_ESCAPED_TOKENS, which splits the
      list at ',' (and strips whitespaces at the around the delimiter). That
      differs from what %VALUE_STRSPLIT_MODE_MULTILIST_WITH_ESCAPE did, which
      also considered whitespace a delimiter.
      
      So, we need a new mode %VALUE_STRSPLIT_MODE_ESCAPED_TOKENS_WITH_SPACES
      which replaces the previous mode.
      
      Note that the previous implementation did almost the same thing. In
      fact, I cannot imagine examples where they behaved differently, but
      my feeling is that there might be some edge cases where this changes
      behavior.

      cli: fix splitting of multilist property in setter · 758bf326
      Thomas Haller authored
      The modes VALUE_STRSPLIT_MODE_OBJLIST* and VALUE_STRSPLIT_MODE_MULTILIST* are
      different. We must use the right mode.
      
      For example, _get_fcn_match_interface_name() concatenates the interface-names
      with space. So, the tokenizer of the setter must also use space as delimiter.
      VALUE_STRSPLIT_MODE_MULTILIST_WITH_ESCAPE does that correctly,
      VALUE_STRSPLIT_MODE_OBJLIST_WITH_ESCAPE does not.

      platform: compare routing rules according to kernel support for FRA_L3MDEV · b6ff02e7

      Also, in nm_platform_routing_rule_cmp() always compare the routing
      table field, also if l3mdev is set. For kernel, we cannot set table and
      l3mdev together, hence such rules don't really exist (or if we try to
      configure it, it will be rejected by kernel). But as far as
      nm_platform_routing_rule_cmp() is concerned, if the table is set,
      always compare it.

      platform: compare routing rules according to kernel support for FRA_PROTOCOL · ef4f8ccf
      Thomas Haller authored
      For routes and routing rules, kernel uses a certain (not stictly defined) set
      of attributes to decide whether to routes/rules are identical.
      
      That is a problem, as different kernel versions disagree on whether
      two routes/rules are the same (EEXIST) or not.
      
      Note that when NetworkManager tries to add a rule with protocol set to
      anything but RTPROT_UNSPEC, then kernel will ignore the attribute if it
      doesn't have support for it. Meaning: the added rule will have a
      different protocol setting then intended.
      
      Note that NMPRulesManager will add a rule if it doesn't find it in the
      platform cache so far. That means, when looking into the platform cache
      we must ignore or honor the protocol like kernel does.
      
      This does not only affect FRA_PROTOCOL, but all attributes where kernel
      and NetworkManager disagrees. But the protocol is the most prominent
      one, because the rules tracked by nmp_rules_manager_track_default()
      specify the protocol.

      platform: refactor detecting kernel features · ee269b31
      Thomas Haller authored
      Next we will need to detect more kernel features. First refactor the
      handling of these to require less code changes and be more efficient.
      A plain nm_platform_kernel_support_get() only reqiures to access an
      array in the common case.
      
      The other important change is that the function no longer requires a
      NMPlatform instance. This allows us to check kernel support from
      anywhere. The only thing is that we require kernel support to be
      initialized before calling this function. That means, an NMPlatform
      instance must have detected support before.

      libnm: minor refactoring of _nm_utils_bridge_vlan_verify_list() · a358da09
      Thomas Haller authored
      - if there is only one vlan in the list, then we can return success
        early. That is, because one NMBridgeVlan instance is always valid
        due to the way how users must use the API to construct the element.
      
      - the implementation for check_normalizable is only correct, if there
        are no duplicate or overlapping ranges. Assert for that. In fact,
        all callers first check for errors and then for normalizable errors.
      
      - avoid duplicate calls to nm_bridge_vlan_get_vid_range(). There are
        duplicate assertions that we don't need.
      
      - only check for pvid once per range.
      
      - combine calls to g_hash_table_contains() and g_hash_table_add().
