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.
2015-11-16siphash24: change result argument to uint64_tMartin Pitt
Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which enforce pointer alignment this fixes crashes when we previously cast an unaligned array to uint64_t*, and on others this should at least improve performance as the compiler now aligns these properly. This also simplifies the code in most cases by getting rid of typecasts. The only place which we can't change is struct duid's en.id, as that is _packed_ and public API, so we can't enforce alignment of the "id" field and have to use memcpy instead.

2015-10-25util-lib: split out fd-related operations into fd-util.[ch]Lennart Poettering
There are more than enough to deserve their own .c file, hence move them over.
2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-10-05document ability to disable MACAddressPolicyJacob Keller
While it is currently possible to either not set MACAddressPolicy or set it to a value different from "persistent" or "random", it is not obvious that a user can do so. Add a policy, "none", which simply retains kernel MAC addresses (same as not filling in the policy at all) and document it so that users are aware of this setting.

2015-06-02udev: add some assertsTom Gundersen
Mostly for documentation purposes.
2015-05-21udev: link-config - fix corruptionTom Gundersen
The parser used for MTU and Speed expects them to be size_t, not unsigned int. This caused a corruption in the rest of the structure. Reported by David O Neill <david.m.oneill@intel.com>.
2015-05-16udevd: net - fix leak in .link configTom Gundersen
Path, Driver and Type are now strv rather than strings, so free them properly.

2015-03-13Use space after a silencing (void)Zbigniew Jędrzejewski-Szmek
We were using a space more often than not, and this way is codified in CODING_STYLE.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-06udev: net_setup - clarify reason for failure of persistent mac address policyTom Gundersen
2015-01-12udev: link_config - modernize a bit and fix leakesTom Gundersen
Not all of the link_config struct was getting freed.
2014-12-08udev: link-config - simplify net-matchTom Gundersen
2014-12-05net_setup/networkd: warn if matching is done on possibly unstable ifnameTom Gundersen
2014-12-04udev: net_setup - allow matching on OriginalName=Tom Gundersen
This has been requested repeatedly, so let's give it a go. We explicitly do not allow matching on names that have already been changed (from a previous udev run, or otherwise), and matching on unpredictable names (ethX) is discouraged (but not currently disallowed). We also currently allow: [Match] Name=veth0 [Link] Name=my-name0 SomeOtherSetting=true Which means that the link file will be applied the first time it is invoked, but not on subsequent invocations, which may be surprising.

2014-11-28udev,update-done: more log_xyz_errno() conversionsLennart Poettering
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().
2014-11-07util: simplify proc_cmdline() to reuse get_process_cmdline()Lennart Poettering
Also, make all parsing of the kernel cmdline non-fatal.

2014-08-12networkd: link - split out dhcp4 handlingTom Gundersen
2014-08-12udev: link-config - fix naming policyTom Gundersen
Don't exit the name-finding loop when the 'kernel' policy is detected. We should still find a fallback name if possible in the (very likely) case that no kernel name is set at all.
2014-08-12udev: link-config - whitespaceTom Gundersen
Don't overflow 80 cols unneccessarily (we are ok with doing it when it improves readability, but that's not the case here).
2014-08-08udev: link_setup - respect kernel name assign policyTom Gundersen
Newer kernels export meta-information about the origin of an ifname. Respect this from the ifname rename logic. We do not rename any interfaces that was originally named by userspace, nor once which have already been renamed from userspace. Moreover, we optionally do not (the default) rename interfaces which the kernel claims to have named in a predictable way.
2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird
2014-07-16Be more careful when checking for empty filesZbigniew Jędrzejewski-Szmek
If we want to avoid reading a totally empty file, it seems better to check after we have opened the file, not before.
2014-07-16Let config_parse open file where applicableZbigniew Jędrzejewski-Szmek
Special care is needed so that we get an error message if the file failed to parse, but not when it is missing. To avoid duplicating the same error check in every caller, add an additional 'warn' boolean to tell config_parse whether a message should be issued. This makes things both shorter and more robust wrt. to error reporting.

2014-07-07udev: link_config - ignore errors due to missing MAC addressTom Gundersen
Otherwis, we get misleading error messages on links with MACs. Reported by Leonid Isaev.
2014-07-03udev: net_setup_link - add a bit more loggingTom Gundersen
2014-06-13udev: fix invalid free() in enable_name_policy()Andreas Henriksson
static bool enable_name_policy(...) in ./src/udev/net/link-config.c calls proc_cmdline(...) to get "line" initialized, but proc_cmdline(...) does not guarantee that atleast when both conditions (detect_container(NULL) > 0) and read_full_file(...) returned < 0.

2014-04-20udev: link-config - treat any non-random mac address as persistentTom Gundersen
The address may be already changed by other processes, or set when creating the netdev from userspace.
