2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().

2014-11-27log: rearrange log function namingLennart Poettering
- Rename log_meta() → log_internal(), to follow naming scheme of most other log functions that are usually invoked through macros, but never directly. - Rename log_info_object() to log_object_info(), simply because the object should be before any other parameters, to follow OO-style programming style.
2014-11-27log: add an "error" parameter to all low-level logging calls and intrdouce ↵Lennart Poettering
log_error_errno() as log calls that take error numbers This change has two benefits: - The format string %m will now resolve to the specified error (or to errno if the specified error is 0. This allows getting rid of a ton of strerror() invocations, a function that is not thread-safe. - The specified error can be passed to the journal in the ERRNO= field. Now of course, we just need somebody to convert all cases of this: log_error("Something happened: %s", strerror(-r)); into thus: log_error_errno(-r, "Something happened: %m");
2014-11-27networkd: fix kernel rtnl receive buffer overrun errorAlin Rauta
We got the following error when running systemd on a device with many ports: "rtnl: kernel receive buffer overrun Event source 'rtnl-receive-message' returned error, disabling: No buffer space available" I think the kernel socket receive buffer queue should be increased. The default value is taken from: "/proc/sys/net/core/rmem_default", but we can overwrite it using SO_RCVBUF socket option. This is already done in networkd for other sockets. For example, the bus socket (sd-bus/bus-socket.c) has a receive queue of 8MB. In our case, the default is 208KB. Increasing the buffer receive queue for manager socket to 512KB should be enough to get rid of the above error. [tomegun: bump the limit even higher to 8M]
2014-11-27networkd: route - allow routes without a gatewayGavin Li
For IPv6, the kernel returns EINVAL if a route is added with the RTA_GATEWAY attribute set to in6addr_any (::). A route without a gateway is useful in some situations, such as layer 3 tunneling (sit, gre, etc.). This patch prevents the RTA_GATEWAY attribute from being added when route.in_addr is ip6addr_any (::).

Now that we only have one file with condition implementations around, we can drop the -util suffix and simplify things a bit.
2014-11-04sd-event: rename sd_event_source_set_name() to sd_event_source_get_name()Lennart Poettering
To mirror the recent name change of the concept for sd_bus objects, follow the same logic for sd_event_source objects, too.

2014-10-11sd-dhcp-client: support non-Ethernet hardware addressesDan Williams
Like Infiniband. See RFC 4390 section 2.1 for details on DHCP and Infiniband; chaddr is zeroed, hlen is set to 0, and htype is set to ARPHRD_INFINIBAND because IB hardware addresses are 20 bytes in length.
2014-09-29Do not format USEC_INFINITY as NULLZbigniew Jędrzejewski-Szmek
systemctl would print 'CPUQuotaPerSecUSec=(null)' for no limit. This does not look right. Since USEC_INFINITY is one of the valid values, format_timespan() could return NULL, and we should wrap every use of it in strna() or similar. But most callers didn't do that, and it seems more robust to return a string ("infinity") that makes sense most of the time, even if in some places the result will not be grammatically correct.

2014-09-16sd-bus: sd_bus_message_get_errno should only return positive errnoThomas Hindoe Paaboel Andersen
sd_bus_message_get_errno can currently return either a number of different poitive errno values (from bus-error-mapping), or a negative EINVAL if passed null as parameter. The check for null parameter was introduced in 40ca29a1370379d43e44c0ed425eecc7218dcbca at the same as the function was renamed from bus_message_to_errno and made public API. Before becoming public the function used to return only negative values. It is weird to have a function return both positive and negative errno and it generally looks like a mistake. The function is guarded by the --enable-kdbus flags so I wonder if we still have time to fix it up? It does not have any documentation yet. However, except for a few details it is just a convenient way to call sd_bus_error_get_errno which is documented to return only positive errno. This patch makes it return only positive errno and fixes up the two calls to the function that tried to cope with both positive and negative values.
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.

2014-09-08networkd: allow specification of DHCP route metricAngus Gibson
This lets the routing metric for links to be specified per-network, still defaulting to DHCP_ROUTE_METRIC (1024) if unspecified. Hopefully this helps with multiple interfaces configured via DHCP.

As the comment says, the passed in callback must always be invoked, or the underlying link will hang. This was missed when reworking the code, so add it back in.
2014-08-19networkd: link - don't enforce ENSLAVING stateTom Gundersen
We are only guaranteed to stay in ENSLAVING state whilst enslaving by bridges/bonds, not when adding stacked devices (as then the underlying device can be IFF_UP'ed and configured in parallel), so drop these asserts.
