2015-02-12Revert "tree-wide: Always use recvmsg with MSG_CMSG_CLOEXEC"Lennart Poettering
This reverts commit d6d810fbf8071f8510450dbacd1d083f37603656. It's apparently not OK to pass MSG_CMSG_CLOEXEC to recvmsg() of raw sockets.

2015-02-04timesyncd: downgrade more log messages from LOG_INFO to LOG_DEBUGLennart Poettering
https://bugs.freedesktop.org/show_bug.cgi?id=87505 Let's make timesyncd less chatty.
2015-02-04timesyncd: reduce log chattiness a bitLennart Poettering
Let's downgrade the statistics output from LOG_INFO to LOG_DEBUG. https://bugs.freedesktop.org/show_bug.cgi?id=88926
2015-01-27timesyncd: set RLIMIT_NPROC to 2Lennart Poettering
This way timesyncd cannot be used to fork(). Note that it generally is not safe to use RLIMIT_NPROC, since it breaks running the same daemon in multiple containers if they do not use user namespacing. However, timesyncd is excepted from running in a container anyway, hence it is safe in this case.
2015-01-18timesyncd: consider too long packets as invalidTopi Miettinen
If the received NTP message from server didn't fit to our buffer, either it is doing something nasty or we don't know the protocol. Consider the packet as invalid. (David: add parantheses around conditional)
2014-12-25timesync: remove square(), use pow insteadCristian Rodríguez
In any case, the compiler generates the same code inline and never actually calls the library function.

2014-11-28treewide: another round of simplificationsMichal Schmidt
Using the same scripts as in f647962d64e "treewide: yet more log_*_errno + return simplifications".
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: drop unnecessary trailing \n in log_*() callsMichal Schmidt
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().

2014-09-02timesyncd: don't reset polling interval when reselecting serverKay Sievers
Original patch from: Miroslav Lichvar <mlichvar@redhat.com>
2014-09-02timesyncd: allow two missed replies before reselecting serverMiroslav Lichvar
After receiving a reply from the server, allow two missed replies before switching to another server to avoid unnecessary clock hopping when packets are getting lost in the network.

2014-09-02timesyncd: wait before reconnecting to first serverMiroslav Lichvar
When all servers are exhausted, wait for one poll interval before trying to connect again to the first server in the list. Also, keep increasing the polling interval to make sure a client not getting any valid replies will not send requests to any server more frequently than is allowed by the maximum polling interval.

2014-08-29timesyncd: check root distanceMiroslav Lichvar
NTPv4 servers don't reply with unsynchronized status when they lost synchronization, they only keep increasing the root dispersion and it's up to the client to decide at which point they no longer consider it synchronized. Ignore replies with root distance over 5 seconds.

The kernel timestamp (recv_time) is made earlier than current time (now_ts), use the timestamp captured before sending packet directly.

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
2014-07-27core: only set the kernel's timezone when the RTC runs in local timeKay Sievers
We can not reliably manage any notion of local time. Every daylight saving time change or time zone change by traveling will make the time jump, and the local time might jump backwards which creates unsolvable problems with file timestamps. We will no longer tell the kernel our local time zone and leave everything set to UTC. This will effectively turn FAT timestamps into UTC timestamps. If and only if the machine is configured to read the RTC in local time mode, the kernel's time zone will be configured, but systemd-timesysnc will disable the kernel's system time to RTC syncing. In this mode, the RTC will not be managed, and external tools like Windows bootups are expected to manage the RTC's time. https://bugs.freedesktop.org/show_bug.cgi?id=81538
2014-07-17sd-network: fix parameter order for sd_network_monitor_new()Lennart Poettering
Constructors should return the object they created as first parameter, except when they are generated as a child/member object of some other object in which case that should be first.
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.

2014-07-15timesyncd: only listen to clock changes when connectedZbigniew Jędrzejewski-Szmek
This reverts previous commit and applies a different fix. manager_clock_watch() callback calls manager_send_request() to kick off a resync. We can only do that when we're actually connected to something. It is not useful to setup the callback from manager_new(). Now the callback will be dropped in manager_connect() and requested in manager_begin(). https://bugs.freedesktop.org/show_bug.cgi?id=80932
