2014-06-22fix in_addr_prefix_intersect for 32bitsMarc-Antoine Perennou
shifting from a non fixed number of bits >= to the size of the type leads to weird results, handle the special case of << 32 to fix it. This was causing a test failure from test-socket-util: Assertion 'in_addr_prefix_intersect(f, &ua, apl, &ub, bpl) == result' failed at /var/tmp/paludis/build/sys-apps-systemd-scm/work/systemd-scm/src/test/test-socket-util.c:147, function test_in_addr_prefix_intersect_one(). Aborting. Minimal reproducer: paludisbuild@Lou /tmp $ cat test.c static void test(unsigned m) { unsigned nm = 0xFFFFFFFFUL << (32-m); printf("%u: %x\n", m, nm); } int main (void) { test(1); test(0); return 0; } paludisbuild@Lou /tmp $ gcc -m32 -std=gnu99 test.c -o test32 paludisbuild@Lou /tmp $ ./test32 1: 80000000 0: ffffffff paludisbuild@Lou /tmp $ gcc -std=gnu99 test.c -o test64 paludisbuild@Lou /tmp $ ./test64 1: 80000000 0: 0

2014-02-19make gcc shut upLennart Poettering
If -flto is used then gcc will generate a lot more warnings than before, among them a number of use-without-initialization warnings. Most of them without are false positives, but let's make them go away, because it doesn't really matter.

2013-12-24util: unify SO_PEERCRED/SO_PEERSEC invocationsLennart Poettering
Introduce new call getpeercred() which internally just uses SO_PEERCRED but checks if the returned data is actually useful due to namespace quirks.

2013-11-06socket-proxyd: rework to support multiple sockets and splice()-based ↵Lennart Poettering
zero-copy network IO This also drops --ignore-env, which can't really work anymore if we allow multiple fds. Also adds support for pretty printing of peer identities for debug purposes, and abstract namespace UNIX sockets. Also ensures that we never take more connections than a certain limit.
2013-11-06active: rework make_socket_fd() to be based on socket_address_listen()Lennart Poettering
Among other things this makes sure we set SO_REUSEADDR which is immensely useful.

Fixes minor leak in error path in device.c.
2013-09-26core: rework how we match mount units against each otherLennart Poettering
Previously to automatically create dependencies between mount units we matched every mount unit agains all others resulting in O(n^2) complexity. On setups with large amounts of mount units this might make things slow. This change replaces the matching code to use a hashtable that is keyed by a path prefix, and points to a set of units that require that path to be around. When a new mount unit is installed it is hence sufficient to simply look up this set of units via its own file system paths to know which units to order after itself. This patch also changes all unit types to only create automatic mount dependencies via the RequiresMountsFor= logic, and this is exposed to the outside to make things more transparent. With this change we still have some O(n) complexities in place when handling mounts, but that's currently unavoidable due to kernel APIs, and still substantially better than O(n^2) as before. https://bugs.freedesktop.org/show_bug.cgi?id=69740

2013-04-11errno is positiveZbigniew Jędrzejewski-Szmek
Make sure we compare errno against positive error codes. The ones in hwclock.c and install.c can have an impact, the rest are unlikely to be hit or in code that isn't widely used. Also check that errno > 0, to help gcc know that we are returning a negative error code.
2013-03-29Always use errno > 0 to help gccZbigniew Jędrzejewski-Szmek
gcc thinks that errno might be negative, and functions could return something positive on error (-errno). Should not matter in practice, but makes an -O4 build much quieter.

2012-10-30shared, core: do not always accept numbers in string lookupsMichal Schmidt
The behaviour of the common name##_from_string conversion is surprising. It accepts not only the strings from name##_table but also any number that falls within the range of the table. The order of items in most of our tables is an internal affair. It should not be visible to the user. I know of a case where the surprising numeric conversion leads to a crash. We will allow the direct numeric conversion only for the tables where the mapping of strings to numeric values has an external meaning. This holds for the following lookup tables: - netlink_family, ioprio_class, ip_tos, sched_policy - their numeric values are stable as they are defined by the Linux kernel interface. - log_level, log_facility_unshifted - the well-known syslog interface. We allow the user to use numeric values whose string names systemd does not know. For instance, the user may want to test a new kernel featuring a scheduling policy that did not exist when his systemd version was released. A slightly unpleasant effect of this is that the name##_to_string conversion cannot return pointers to constant strings anymore. The strings have to be allocated on demand and freed by the caller.

2012-04-12relicense to LGPLv2.1 (with exceptions)Lennart Poettering
We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

Only 34 of 74 tools need libselinux linked, and libselinux is a pain with its unconditional library constructor.
