resulting name is actually valid Also, rename filename_is_safe() to filename_is_valid(), since it actually does a full validation for what the kernel will accept as file name, it's not just a heuristic.
2014-12-12journal: fix dangling 'else' ambiguityDavid Herrmann
Rework the sd-journal iterators to avoid dangling 'else' ambiguity. For a detailed explanation, see: commit bff686e2a981ccd0888cdf1981977d24320f1770 Author: David Herrmann <dh.herrmann@gmail.com> Date: Fri Dec 12 09:43:54 2014 +0100 hwdb: fix dangling 'else' ambuguity
2014-12-12hwdb: fix dangling 'else' ambuguityDavid Herrmann
Imagine the following use of hwdb: if (condition_A) SD_HWDB_FOREACH_PROPERTY(hwdb, modalias, key, value) operation_A(key, value); else log_error("..."); This should work just fine, but but definitely does not what you would expect. Due to how SD_HWDB_FOREACH_PROPERTY is defined, the dangling 'else' is linked to the hidden 'if' statement in the macro instead of the outer 'if (condition_A)'. This is unexpected and really annoying to debug. Fix this by never leaving un-finished if-statements in SD_HWDB_FOREACH_PROPERTY(). We simply inverse the if() statement and explicitly add an 'else'-branch. This way, the statement is closed and all ambuguities are resolved.
2014-12-12hwdb: FOREACH_HWDB_PROPERTY -> SD_HWDB_FOREACH_PROPERTYDavid Herrmann
Lets not pollute the global namespace. Prefix all our exported names and macros with SD_HWDB_*.

2014-12-11libudev: make libudev-hwdb a wrapper around sd-hwdbTom Gundersen
2014-12-11libsystemd: add sd-hwdb libraryTom Gundersen
This is libudev-hwdb, but decoupled from libudev and in the libsystemd style. The core code is unchanged, apart from the following minor changes: - hwdb.bin located in /**/systemd/hwdb/ take preference over the ones located in /**/udev/ - properties are stored internally in an OrderedHashmap, rather than a linked list. - a new API call allows individual properties to be queried directly, rather than iterating over them all - the iteration over properties have been moved inside the library, rather than exposing a list directly - the unused 'flags' parameter was dropped
2014-12-11bus: sync with kdbus.gitDavid Herrmann
Sync up with recent kdbus changed: * several ioctls gained .size and .items members (but still unused) * CMD_SEND gained its own ioctl structure * several members of kdbus_msg were dropped as they were only used during SEND, not during RECV etc. * CMD_RECV and CMD_SEND now share a kdbus_reply member which contains the offset and size of the returned message.
2014-12-11bus: zero cmd_free before passing to ioctlDavid Herrmann
Make sure the whole cmd_free object is zeroed before passing it into the kernel. This makes valgrind happy and makes us future proof.
2014-12-11bus: fix memfd-cache regarding memfd offsetsDavid Herrmann
We must restore part->mmap_begin when poping memfds from the memfd-cache. We rely on the memfds to be unsealed, so we can be sure that we own the whole FD. Therefore, simply set part->mmap_begin to the same as part->data. This fixes test-bus-kernel-benchmark.

Let's stick to generic sections that describe the general technology, instead of specific per-object sections, unless we really have a reason to do that otherwise.

2014-12-10networkd-dhcp6: Support ICMPv6 Other informationPatrik Flykt
When ICMPv6 Other information is received, enable Information request in DHCPv6. If the DHCPv6 client already exists, only update the client if there is a transition from Other to Managed state.
2014-12-10networkd-dhcp6: Move ICMPv6 and DHCPv6 configuration to new filePatrik Flykt
Handle all aspects of ICMPv6 and DHCPv6 in a file of its own as is done with DHCPv4 and IPv4LL.
2014-12-10test-dhcp6-client: Add a simple Information Request test casePatrik Flykt
Start the DHCPv6 test case by sending an Information Request, verifying the reply and continuing at once with the normal address acquisition procedure. Reuse the DHCPv6 Solicit Reply so that the client code is verified to ignore any erroneously added IPv6 address information.
2014-12-10sd-dhcp6-client: Implement Information Request messagePatrik Flykt
Implement Information Request message according to RFC 3315, section 18.1.5. with the excepion that the first message is not delayed by a random amount. Instead systemd-networkd is supposed to take care of desynchronizing between other clients. Initialize the DHCPv6 client structure in sd_dhcp6_client_start() as this allows toggling between information request and normal DHCPv6 address aquisition modes.
2014-12-10sd-dhcp6-lease: Return only -EINVAL when a NULL lease is suppliedPatrik Flykt
Suppyling a NULL lease is not a condition that needs to be asserted, returning -EINVAL is informative enough to the caller. This simplifies calling code and doesn't falsely indicate that something erroneous was attempted.
2014-12-10sd-dhcp6-client: Make end of successfull option parsing explicitPatrik Flykt
When all DHCPv6 options have been parsed, dhcp6_option_parse() returns -ENOMSG. Explicitely set the return value to indicate success so that later code does not need to take this special value into account.
2014-12-10test: fix some tests when running inside a containerJan Synacek
2014-12-10virt: when detecting containers and /run/systemd/container cannot be read, ↵Lennart Poettering
check /proc/1/environ This way, we should be in a slightly better situation if a container is booted up with only a shell as PID 1. In that case /run/systemd/container will not be populated, and a check for it hence be ineffective. Checking /proc/1/environ doesn't fully fix the problem though, as the file is only accessible with privileges. This means if PID 1 is not systemd, and if privileges have been dropped the container detection will continue to fail.
2014-12-09systemctl: fix invalid free when enabling sysv services failsZbigniew Jędrzejewski-Szmek
The error was introduced in v215-343-g60731f32f1 'systemctl: do not bother to mutate state on error', by causing strv_free to attempt to free a static string. Simplify the whole thing by always keeping the array in valid state.

2014-12-09treewide: sanitize loop_writeZbigniew Jędrzejewski-Szmek
loop_write() didn't follow the usual systemd rules and returned status partially in errno and required extensive checks from callers. Some of the callers dealt with this properly, but many did not, treating partial writes as successful. Simplify things by conforming to usual rules.

2014-12-09journal: optimize iteration: skip files that cannot improve current ↵Michal Schmidt
candidate entry Suppose that while iterating we have already looked into a journal file and got a candidate for the next entry. And we are considering to look into another journal file because it may contain an entry that is nearer to the current location than the candidate. We should skip the whole journal file if we can tell by looking at its header that none of its entries can precede the candidate. Before: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m20.518s user 0m19.989s sys 0m0.328s After: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m9.445s user 0m9.228s sys 0m0.213s
2014-12-09journal: optimize iteration: skip whole files behind current locationMichal Schmidt
Interleaving of entries from many journal files is expensive. But there is room for optimization. We can skip looking into journal files whose entries all lie before the current iterating location. We can tell if that's the case from looking at the journal file header. This saves a huge amount of work if one has many of mostly not interleaved journal files. On my workstation with 90 journal files in /var/log/journal/ID/ totalling 3.4 GB I get these results: Before: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 5m54.258s user 2m4.263s sys 3m48.965s After: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m20.518s user 0m19.989s sys 0m0.328s The high "sys" time in the original was caused by putting more stress on the mmap-cache than it could handle. With the patch the working set now consists of fewer mmap windows and mmap-cache is not thrashing.
