2014-11-03core: introduce ConditionSecurity=auditLennart Poettering
And conditionalize journald audit support with it

2014-11-01calendarspec: add constant for weekdays_bitsDaniele Medri
2014-11-01sd-dhcp-lease: use shared default prefixlen functionTom Gundersen
Also change the default prefixlen function to only access the first octet of the in_addr.

2014-10-31ptyforward: rework PTY forwarder logic used by nspawn to utilize the normal ↵Lennart Poettering
event loop We really should not run manual event loops anymore, but standardize on sd_event, so that we can run sd_bus connections from it eventually.
2014-10-31Make bus errno mappings non-staticZbigniew Jędrzejewski-Szmek
__attribute__((used)) is not enough to force static variables to be carried over to a compiled program from a library. Mappings defined in libsystemd-shared.a were not visible in the compiled binaries. To ensure that the mappings are present in the final binary, the tables are made non-static and are given a real unique name by which they can be referenced. To use a mapping defined not in the local compilation unit (e.g. in a library) a reference to the mapping table is added. This is done by including a declaration in the header file. Expected values in test-engine are fixed to reflect the new mappings.
2014-10-31shared/install: avoid prematurely rejecting "missing" unitsDave Reisner
f7101b7368df copied some logic to prevent enabling masked units, but also added a check which causes attempts to enable templated units to fail. Since we know the logic beyond this check will properly handle units which truly do not exist, we can rely on the unit file state comparison to suffice for expressing the intent of f7101b7368df. ref: https://bugs.archlinux.org/task/42616

2014-10-30Convert the rest to sd_bus_errnomapZbigniew Jędrzejewski-Szmek
I tried to preserve most errno values, but in some cases they were inconsistent (different errno values for the same error name) or just mismatched.
2014-10-30hashmap: rewrite the implementationMichal Schmidt
This is a rewrite of the hashmap implementation. Its advantage is lower memory usage. It uses open addressing (entries are stored in an array, as opposed to linked lists). Hash collisions are resolved with linear probing and Robin Hood displacement policy. See the references in hashmap.c. Some fun empirical findings about hashmap usage in systemd on my laptop: - 98 % of allocated hashmaps are Sets. - Sets contain 78 % of all entries, plain Hashmaps 17 %, and OrderedHashmaps 5 %. - 60 % of allocated hashmaps contain only 1 entry. - 90 % of allocated hashmaps contain 5 or fewer entries. - 75 % of all entries are in hashmaps that use trivial_hash_ops. Clearly it makes sense to: - store entries in distinct entry types. Especially for Sets - their entries are the most numerous and they require the least information to store an entry. - have a way to store small numbers of entries directly in the hashmap structs, and only allocate the usual entry arrays when the direct storage is full. The implementation has an optional debugging feature (enabled by defining the ENABLE_HASHMAP_DEBUG macro), where it: - tracks all allocated hashmaps in a linked list so that one can easily find them in gdb, - tracks which function/line allocated a given hashmap, and - checks for invalid mixing of hashmap iteration and modification. Since entries are not allocated one-by-one anymore, mempools are not used for entries. Originally I meant to drop mempools entirely, but it's still worth it to use them for the hashmap structs. My testing indicates that it makes loading of units about 5 % faster (a test with 10000 units where more than 200000 hashmaps are allocated - pure malloc: 449±4 ms, mempools: 427±7 ms). Here are some memory usage numbers, taken on my laptop with a more or less normal Fedora setup after booting with SELinux disabled (SELinux increases systemd's memory usage significantly): systemd (PID 1) Original New Change dirty memory (from pmap -x 1) [KiB] 2152 1264 -41 % total heap allocations (from gdb-heap) [KiB] 1623 756 -53 %
2014-10-30mempool: add a zeroing alloc functionMichal Schmidt
Add mempool_alloc0_tile(). It's like mempool_alloc_tile(), but it initializes the allocated tile's memory to zero.
2014-10-30util: add log2u(), log2u_round_up()Michal Schmidt
Two's logarithms for unsigned.

2014-10-30memfd: always create our memfds with CLOEXEC setLennart Poettering
We really shouldn't create fds ever that have the flag unset.

needing entropy Doesn't require an fd, and could be a bit faster, so let's make use of it, if it is available.

something fails

2014-10-27shared: in-addr-utils - add default_subnet_mask and default_prefixlen methodsTom Gundersen
These use the (deprecated) IPv4 address classes to deduce the corresponding subnet masks. This is useful when addresses without subnet masks and prefix lengths are given. Make use of these new functions from sd-dhcp-lease.

Function queries system hostname and applies changes only when necessary. Also, migrate all client of sethostname to sethostname_idempotent while at it.

2014-10-24calendar: make freeing a calendar spec object deal fine with NULLLennart Poettering
In order to make object destruction easier (in particular in combination with _cleanup_) we usually make destructors deal with NULL objects as NOPs. Change the calendar spec destructor to follow the same scheme.

2014-10-23selinux: clean up selinux label function namingLennart Poettering
2014-10-23selinux: simplify and unify loggingLennart Poettering
Normally we shouldn#t log from "library" functions, but SELinux is weird, hence upgrade security messages uniformly to LOG_ERR when in enforcing mode.
2014-10-23selinux: rework label query APIsLennart Poettering
APIs that query and return something cannot silently fail, they must either return something useful, or an error. Fix that. Also, properly rollback socket unit fd creation when something goes wrong with the security framework.

of the matching selinux code
2014-10-23smack: never follow symlinks when relabellingLennart Poettering
previously mac_smack_apply(path, NULL) would operate on the symlink itself while mac_smack_apply(path, "foo") would follow the symlink. Let's clean this up an always operate on the symlink, which appears to be the safer option.
2014-10-23smack: rework smack APIs a bitLennart Poettering
a) always return negative errno error codes b) always become a noop if smack is off c) always take a NULL label as a request to remove it
2014-10-23mac: rename all calls that apply a label mac_{selinux|smack}_apply_xyz(), ↵Lennart Poettering
and all that reset it to defaults mac_{selinux|smack}_fix() Let's clean up the naming schemes a bit and use the same one for SMACK and for SELINUX.
