Hi all, I have used the chrony-v1.18 package, which is a server/client-based systemtime-adjusting tool with kernel linux-2.4.19-xfs-r1 with gentoo and maybe prior versions with kernels 2.2.18 and 2.2.19 at slackware 7.0 in the past with no problems. currently I am working on getting freeswan getting work, so I have got after emerge rsync the new linux-2.4.19-crypto-r7 which I have compiled fine. But chronyd has a timing problems, now. let's have a look at syslog: ---schnipp--- Nov 6 20:59:23 killerghost chronyd[6105]: chronyd version V1_18 starting Nov 6 20:59:23 killerghost chronyd[6105]: Linux kernel major=2 minor=4 patch=19 Nov 6 20:59:23 killerghost chronyd[6105]: Unexpected condition [adjtimex failed for set_frequency] at sys_linux.c:442, core dumped ---schnapp--- I tried to solve the problem by looking at http://chrony.sunsite.dk/ if this problem is known, and it is. It is mentioned at http://chrony.sunsite.dk/faq.php#question_7.1 with the following text: ---schnipp--- 7.1. chronyd crashes after a syslog message "adjtimex failed for set frequency" The usual cause is that the kernel is running with a different value of 'HZ' (the timer interrupt rate) than the value that was found in the kernel header files when chrony was compiled. The chrony.conf file can include options to modify the HZ value (see the discussion of linux_hz and linux_freq_scale in the documentation), however the problem is to find the value of HZ being used. At the end of the chrony v1.18 section of the download page you'll find instructions on how to do this. ---schnapp--- so I tried, what is discribed at http://chrony.sunsite.dk/download.php I patched, compiled, executed the new binary with "./chronyd -f /etc/chrony/chrony.conf" at my local compile directory and this is what sylog said: ---schnipp--- Nov 6 21:30:04 killerghost chronyd[7368]: chronyd version V1_18 starting Nov 6 21:30:04 killerghost chronyd[7368]: Initial txc.tick=1000 txc.freq=0 (0.00000000) txc.offset=0 hz=100 shift_hz=7 Nov 6 21:30:04 killerghost chronyd[7368]: Linux kernel major=2 minor=4 patch=19 Nov 6 21:30:04 killerghost chronyd[7368]: calculated_freq_scale=0.99902439 freq_scale=0.99902439 Nov 6 21:30:04 killerghost chronyd[7368]: Unexpected condition [adjtimex failed for set_frequency, freq_ppm=7.8130e+01 scaled_freq=-2.1848 e+01 required_tick=10001] at sys_linux.c:445, core dumped ---schnapp--- I calculated the txc.tick value like described, added the two new lines as described, executed above mentioned line agein. syslog claimes this: ---schnipp--- Nov 6 21:34:44 killerghost chronyd[7415]: chronyd version V1_18 starting Nov 6 21:34:44 killerghost chronyd[7415]: Could not parse linux_hz directive at line 9 Nov 6 21:34:44 killerghost chronyd[7415]: Could not parse linux_freq_scale directive at line 10 Nov 6 21:34:44 killerghost chronyd[7415]: Linux kernel major=2 minor=4 patch=19 Nov 6 21:34:44 killerghost chronyd[7415]: Unexpected condition [adjtimex failed for set_frequency] at sys_linux.c:442, core dumped Nov 6 21:35:28 killerghost chronyd[7438]: chronyd version V1_18 starting Nov 6 21:35:28 killerghost chronyd[7438]: Could not parse linux_hz directive at line 9 Nov 6 21:35:28 killerghost chronyd[7438]: Could not parse linux_freq_scale directive at line 10 Nov 6 21:35:28 killerghost chronyd[7438]: Initial txc.tick=1000 txc.freq=0 (0.00000000) txc.offset=0 hz=100 shift_hz=7 Nov 6 21:35:28 killerghost chronyd[7438]: Linux kernel major=2 minor=4 patch=19 Nov 6 21:35:28 killerghost chronyd[7438]: calculated_freq_scale=0.99902439 freq_scale=0.99902439 Nov 6 21:35:28 killerghost chronyd[7438]: Unexpected condition [adjtimex failed for set_frequency, freq_ppm=7.8130e+01 scaled_freq=-2.1848 e+01 required_tick=10001] at sys_linux.c:445, core dumped ---schnapp--- the kernel compile settings for linux-2.4.19-crypto-r7 are the same like them of linux-2.4.19-xfs-r1, except for the new addiditional settings like crypto. I have no grsecurity settings. I hope that I have given enough information. I am totally lost to solve this on my own, because I am no c-programmer. so, in the hope of help, I am posting this to work on. Please feel free to ask any question to help you with your work. greetings, Sascha
oops, after posting this, I have found bug nr 4233 (should have used chrony and not chronyd like I did before posting). Also I have found, that I am using "=" which should be " " at the two new lines. chrony starts fine, now. I will watch time and repost, if it goes wrong. cu Sascha
please use gentoo-sources-2.4.19-r9 or 2.4.19-r10 both have the freeswan patches, when using these with HZ dependant whatzits, it is important to have HZ set to 100 in the kernel. The next version of the gentoo kernel however will have a new HZ patch which allows the kernel to use any HZ value it wants to and userland will still see 100. Reopen if this discussion doesn't solve.
as I use XFS as filesystem I can't use gentoo-sources-2.4.19-r9 and an emerge -s gentoo-sources gives this as hit. so I can't follow your advice. greetings, Sascha
