2016-02-22tree-wide: make ++/-- usage consistent WRT spacingVito Caputo
Throughout the tree there's spurious use of spaces separating ++ and -- operators from their respective operands. Make ++ and -- operator consistent with the majority of existing uses; discard the spaces.
2016-02-20libsystemd-network: don't abbreviate "callback" as "cb" needlesslyLennart Poettering
This isn't an excercise in creating APIs that are hard to understand, hence let's call a callback a callback.

Better support of OPENPGPKEY, CAA, TLSA packets and tests
2016-02-11Add memcpy_safeZbigniew Jędrzejewski-Szmek
ISO/IEC 9899:1999 §7.21.1/2 says: Where an argument declared as size_t n specifies the length of the array for a function, n can have the value zero on a call to that function. Unless explicitly stated otherwise in the description of a particular function in this subclause, pointer arguments on such a call shall still have valid values, as described in 7.1.4. In base64_append_width memcpy was called as memcpy(x, NULL, 0). GCC 4.9 started making use of this and assumes This worked fine under -O0, but does something strange under -O3. This patch fixes a bug in base64_append_width(), fixes a possible bug in journal_file_append_entry_internal(), and makes use of the new function to simplify the code in other places.
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-01-20dhcp: make DHCP_OPTION_* enum publicBeniamino Galvani
libsystemd-network provides the public function sd_dhcp_client_set_request_option() to enable the request of a given DHCP option. However the enum defining such options is defined in the internal header dhcp-protocol.h. Move the enum definition to the public header sd-dhcp-client.h and properly namespace values.
2015-11-25sd-dhcp: parse error message in DECLINE or NAKTom Gundersen
If a client sends a DECLINE or a server sends a NAK, they can include a string with a message to explain the error. Parse this and print it at debug level.
2015-11-16tree-wide: sort includesThomas Hindoe Paaboel Andersen
Sort the includes accoding to the new coding style.
2015-08-26network: s/user_data/userdata/Lennart Poettering
Everywhere else we call the generic user data pointer just "userdata", rather than "user_data". Let's do this here, too.

2014-05-20sd-dhcp: refactor parse_optionsTom Gundersen
Similar to the previous patch, exchange a length and a pointer with only one offset variable. Also fix the type of the options to be uint8_t[], rather than uint8_t*.
2014-05-20sd-dhcp: refactor dhcp_option_appendTom Gundersen
Store a pointer to the options in the DHCPMessage struct, and pass this together with an offset around, rather than a uint8_t**. This avoids us having to (re)compute the pointer; and changes dhcp_option_append from adjusting both the pointer to the next option and the remaining size of the options, to just adjusting the current offset. This makes the code a bit simpler to follow IMHO, but there should be no functional change.
2014-04-06sd-dhcp-client: move magic cookie into DHCPMessage structTom Gundersen
Also move the checking of it to the main message handler, rather than the options parser. Fix a bug, so we now drop the packet if any of the magic bytes don't match. Before we used to only drop the packet if they were all wrong.
2014-02-28sd-network: add new libraryTom Gundersen
This is similar to sd-login, but exposes the state of networkd rather than logind. Include it in libsystemd-dhcp and rename it to libsystemd-network.
