* Revert "core: link user keyring to session keyring (#6275)" (#6342)Lennart Poettering2017-07-25
| | | | | | | This reverts commit 437a85112e02042b62751395b9e7225628c1b708. The outcome of this isn't that clear, let's revert this for now, see discussion on #6286.

* core: link user keyring to session keyring (#6275)Christian Hesse2017-07-25
| | | | | | | | | | Commit 74dd6b515fa968c5710b396a7664cac335e25ca8 (core: run each system service with a fresh session keyring) broke adding keys to user keyring. Added keys could not be accessed with error message: keyctl_read_alloc: Permission denied So link the user keyring to our session keyring.
* logind: make use of EVIOCSMASK input ioctl to mask out events we aren't ↵Lennart Poettering2017-07-25
| | | | | | | | | | | | | | | interested in This way logind will get woken up only when an actual event took place, and not for every key press on the system. The ioctl EVIOCSMASK was added by @dvdhrm already in October 2015, for the use in logind, among others, hence let's actually make use of it now. While we are at it, also fix usage of the EVIOCGSW ioctl, where we assumed a byte array, even though a unsigned long native endian array is returned.

* missing.h: add AF_VSOCK bitsStefan Hajnoczi2017-07-17
| | | | | | | | | | Ubuntu 14.04 (Trusty) kernel header packages ship without <linux/vm_sockets.h>. Only struct sockaddr_vm and VMADDR_CID_ANY will be needed by elogind and they are simple enough to go in missing.h. CentOS 7 <sys/socket.h> does not define AF_VSOCK. Define it so the code can compile although actual socket(2) calls may fail at runtime if the address family isn't available.
* core: run each system service with a fresh session keyringLennart Poettering2017-07-17
| | | | | | | | | | | | | | | | | This patch ensures that each system service gets its own session kernel keyring automatically, and implicitly. Without this a keyring is allocated for it on-demand, but is then linked with the user's kernel keyring, which is OK behaviour for logged in users, but not so much for system services. With this change each service gets a session keyring that is specific to the service and ceases to exist when the service is shut down. The session keyring is not linked up with the user keyring and keys hence only search within the session boundaries by default. (This is useful in a later commit to store per-service material in the keyring, for example the invocation ID) (With input from David Howells)
* nspawn: support ephemeral boots from imagesLennart Poettering2017-07-17
| | | | | | | | | | | Previously --ephemeral was only supported with container trees in btrfs subvolumes (i.e. in combination with --directory=). This adds support for --ephemeral in conjunction with disk images (i.e. --image=) too. As side effect this fixes that --ephemeral was accepted but ignored when using -M on a container that turned out to be an image. Fixes: #4664
* core: add "khash" API to src/basic/ (as wrapper around kernel AF_ALG)Lennart Poettering2017-07-17
| | | | | | | | | | | | | | | | | Let's take inspiration from bluez's ELL library, and let's move our cryptographic primitives away from libgcrypt and towards the kernel's AF_ALG cryptographic userspace API. In the long run we should try to remove the dependency on libgcrypt, in favour of using only the kernel's own primitives, however this is unlikely to happen anytime soon, as the kernel does not provide Elliptic Curve APIs to userspace at this time, and we need them for the DNSSEC cryptographic. This commit only covers hashing for now, symmetric encryption/decryption or even asymetric encryption/decryption is not available for now. "khash" is little more than a lightweight wrapper around the kernel's AF_ALG socket API.
* Link: port to new ethtool ETHTOOL_xLINKSETTINGSSusant Sahani2017-07-17
| | | | | | | | | | | | | | Link: port to new ethtool ETHTOOL_xLINKSETTINGS This patch defines a new ETHTOOL_GLINKSETTINGS/SLINKSETTINGS API, handled by the new get_link_ksettings/set_link_ksettings . This is a WIP version based on this [kernel patch](https://patchwork.kernel.org/patch/8411401/). commit 0527f1c http://github.com/torvalds/linux/commit/3f1ac7a700d039c61d8d8b99f28d605d489a60cfommit 35afb33

* missing.h: add missing definitions for __O_TMPFILEYann E. MORIN2017-07-05
| | | | | | | | | | | | | | | | | | | Currently, a missing __O_TMPFILE was only defined for i386 and x86_64, leaving any other architectures with an "old" toolchain fail miserably at build time: src/import/export-raw.c: In function 'reflink_snapshot': src/import/export-raw.c:271:26: error: 'O_TMPFILE' undeclared (first use in this function) new_fd = open(d, O_TMPFILE|O_CLOEXEC|O_NOCTTY|O_RDWR, 0600); ^ __O_TMPFILE (and O_TMPFILE) are available since glibc 2.19. However, a lot of existing toolchains are still using glibc-2.18, and some even before that, and it is not really possible to update those toolchains. Instead of defining it only for i386 and x86_64, define __O_TMPFILE with the specific values for those archs where it is different from the generic value. Use the values as found in the Linux kernel (v4.8-rc3, current as of time of commit).
* cgroup: detect cgroup namespacesChristian Brauner2017-07-05

* build: fix missing symbol for old kernel headers (#3530)Andrew Jeddeloh2017-06-16
| | | | | | | | Fix issue where IN6_ADDR_GEN_MODE_STABLE_PRIVACY is undefined but IFLA_INET6_ADDR_GEN_MODE is defined and thus the former does not get fixed in missing.h. This occurs with kernel headers new enough to have the IFLA_INET6_ADDR_GEN_MODE but old enough to not yet have IN6_ADDR_GEN_MODE_STABLE_PRIVACY (e.g. 3.18).

* nspawn: a bench of special fileystems that should not be shiftedDjalal Harouni2017-06-16
| | | | | Add some special filesystems that should not be shifted, most of them relate to the host and not to containers.
* networkd: set IFLA_INET6_ADDR_GEN_MODE as per stable_secretTom Yan2017-06-16
| | | | | | | | Although networkd has option (LinkLocalAddressing=) to toggle IPv6LL autoconfiguration, when it is enabled, the address is autoconfigured by the kernel, but not networkd. Therefore, we do not statically set IFLA_INET6_ADDR_GEN_MODE to IN6_ADDR_GEN_MODE_EUI64, but dynamically depending on whether stable_secret is set, just as what the kernel does by default. Note that this does NOT affect the global addresses configured by networkd.

* build-sys: improve compat with older kernel headersLennart Poettering2017-06-16
| | | | | | | | In 4.2 kernel headers, some netlink defines are missing that we need. missing.h already can add them in, but currently makes this dependent on a definition that these kernels already have. Change the check hence to check for the newest definition in the table, so that the whole bunch of definitions as added in on all kernels lacking this.

* networkd: bump MTU to 1280 for interfaces which have IPv6 enabled (#3077)Susant Sahani2017-06-16
| | | | | | | | | | | | IPv6 protocol requires a minimum MTU of 1280 bytes on the interface. This fixes #3046. Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled. Introduce network_has_static_ipv6_addresses() to find out if any static ipv6 address configured. If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static IPv6 addresses not configured, then IPv6 will be automatically disabled for that interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.
* networkd: allow setting of multicast querier for linux bridge (#3051)Susant Sahani2017-06-16

* basic/missing: add copy_file_rangeZbigniew Jędrzejewski-Szmek2017-06-16
| | | | | syscall numbers based on: https://fedora.juszkiewicz.com.pl/syscalls.html
* missing.h: Explicitly check for IFLA_BRPORT_PROXYARPDaniel Mack2017-06-16
| | | | | | | | | | | | | | | RHEL explicitly disables IFLA_BRPORT_PROXYARP by renaming the enum value. In order to support unpatched builds, we have two options: a) redefine the enum value through missing.h and ignore the fact that it is really unsupported, or b) omit that enum value on rtnl_prot_info_bridge_port_types[] As we are not actually using this netlink type anywhere, and because it is only hooked up for the sake of completeness, this patch opts for the former.
* sd-lldp: move ETHERTYPE_LLDP to missing.hLennart Poettering2017-06-16
| | | | | After all, most ETHERTYPE variables are defined in the system headers, hence define these where we defined all other fill-ins for system headers.
* build-sys: fix type detectionLennart Poettering2017-06-16
| | | | | | | | | | | | | Before this patch existence of char16_t, char32_t, key_serial_t was checked with AC_CHECK_DECLS() which doesn't actually work for types. Correct this to use AC_CHECK_TYPES() instead. Also, while we are at it, change the check for memfd_create() to use AC_CHECK_DECLS() instead of AC_CHECK_FUNCS(). This is a better choice, since a couple of syscalls are defined by glibc but not exported in the header files (pivot_root() for example), and we hence should probably be more picky with memfd_create() too, which glibc might decide to expose one day, but not necessarily in the headers too.
* missing.h: define IFLA_EXT_MASKRabin Vincent2017-06-16
| | | | | | We already define IFLA_PROMISCUITY and some other of these masks in order to allow building with older headers. Define IFLA_EXT_MASK too, which was added in the same kernel version as IFLA_PROMISCUITY (v3.10).
* cgroup2: use new fstype for unified hierarchyAlban Crequy2017-06-16
| | | | | | | | | | | | | | Since Linux v4.4-rc1, __DEVEL__sane_behavior does not exist anymore and is replaced by a new fstype "cgroup2". With this patch, elogind no longer supports the old (unstable) way of doing unified hierarchy with __DEVEL__sane_behavior and elogind now requires Linux v4.4 for unified hierarchy. Non-unified hierarchy is still the default and is unchanged by this patch. https://github.com/torvalds/linux/commit/67e9c74b8a873408c27ac9a8e4c1d1c8d72c93ff

* tree-wide: remove Emacs lines from all filesDaniel Mack2017-05-17
| | | | | This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
* Fix IPv6PrivacyExtension (networkd-ndisc.c)Dominik Hannen2017-05-17
| | | | | This small addition fixes the issues #1982 and #2242. IPv6PrivacyExtension now works as expected even when a RA is received.
* core: socket options fix SCTP_NODELAYSusant Sahani2017-05-17

* Add fallback for kcmp() in case __NR_kcmp is undefinedMike Gilbert2017-03-29
| | | | | IA64 is missing this syscall as of linux-4.2. This works around it until the necessary kernel patch gets merged.
* Major cleanup of all leftovers after rebasing on master.Sven Eden2017-03-14
| | | | | | | | The patching of elogind in several steps with only partly rebasing on a common commit with upstream, left the tree in a state, that was unmergeable with master. By rebasing on master and manually cleaning up all commits, this merge is now possible. However, this process left some orphans, that are cleanup now.
* Add support for building elogind against musl libcSven Eden2017-03-14
| | | | | | | | | | | | | | | | | | | * Check whether printf.h is available and define/undef HAVE_PRINTF_H accordingly. * Added src/shared/parse-printf-format.[hc] by Emil Renner Berthing <systemd@esmil.dk> that provides parse_printf_format() if printf.h is unavailable * Added src/basic/musl_missing.h by Juergen Buchmueller <pullmoll@t-online.de> that implements glibc functions missing in musl libc as macros. * Extended src/basic/musl_missing.h and added src/basic/musl_missing.c providing - program_invocation_name - program_invocation_short_name and - elogind_set_program_name() to set the two where appropriate. * Added calls to elogind_set_program_name() to all main() functions where needed. * A few other fixes to work nicely with musl libc.
