Hi All, I am a Ph.D student at College of Computing Gatech. I have a user level code under /tools/xenstat/xentop/xenloadbalance.c and this uses functions already provided by xenstat.c to get the cpu/mem utilization numbers for all the domains running on a physical machine. Additionally, I am linking GNU scientific library to this code to do some basic statistics at run time. This code has a sliding window implemented with linked list and which for each sliding window this code passes the window data to GSL library for statistics calculation. For example for window size of 10 and polling freq of 1 sec it will pass 10 data elements passed to GSL library functions. I am using statistical functions provided by this GNU library for the analysis of the data generate at runtime such as gsl_stats_mean, gsl_stats_sd etc. I linked gsl and gslcblas with my code as can be seen in Makefile. I could get it compile well and also run well also for some time by which I mean The SIGSEGV fault behavior is very non-deterministic i.e sometimes it happens after few number of polls and sometimes large number of polls given for example I am polling every 1 sec. Also, If I remove the function using GSL library everything runs fine. I ran this code with gdb and I get the SIGSEGV at the gsl_stats_mean function call. Then I ran this code with Valgrind with track-origins=yes and shows the following error multiple times in the beginning of the run - ==20934== Conditional jump or move depends on uninitialised value(s) ==20934== at 0x39BB84899D: __printf_fp (in /lib64/libc-2.5.so) ==20934== by 0x39BB844AD5: vfprintf (in /lib64/libc-2.5.so) ==20934== by 0x39BB847F35: buffered_vfprintf (in /lib64/libc-2.5.so) ==20934== by 0x39BB842A1B: vfprintf (in /lib64/libc-2.5.so) ==20934== by 0x39BB84D357: fprintf (in /lib64/libc-2.5.so) ==20934== by 0x401BA4: calc_load_vector_stats (xenloadbalance.c:227) ==20934== by 0x401F54: main (xenloadbalance.c:307) ==20934== Uninitialised value was created by a stack allocation ==20934== at 0x402682: xenstat_get_node (in /var/lib/xen/images/mahendra/
xen-3.4.3/tools/xenstat/xentop/xenloadbalance) Which tells me that there is something wrong happening with my code calling xenstat_get_node() api. But then the above errors stops and run continues well for a while and then after a while it throws errors again as shown in the following snippet of run from Valgrind. As you can see in the snippet of run below after a while..Uninitialized value error is displayed and then finally there is a fprintf output as - 3.19995e+159 nan nan nan nan nan nan. This will result in SIGSEGV with normal run or even with gdb debugger. Valgrind somehow handles the error and continues again ..and it continue working..But this shows that what went wrong somehow in non-valgrind runs. If you look at this first error produced below there is call to gsl_stats_mean function which calls sqrt function. The origin track tells that the problem again is - ==20934==Â Uninitialised value was created by a stack allocation ==20934==ÂÂÂ at 0x402682: xenstat_get_node (in /var/lib/xen/images/mahendra/xen-3.4.3/tools/xenstat/xentop/xenloadbalance) by xenstat_get_node api. I am providing the snippet of the run below in this email. I am also providing my code and the makefile as an attachment to make sure I get any possible help as soon as possible. I tried gdb debugging with coredump also but I could not get the symbols loaded for Xen. May be I am missing something in the Makefile for Xen build process. I also checked online archives at xen-devel but could not find any patches or way to fix this. I need some help very soon as this is impacting my work. Any pointers/help/patches or any changes even in my code which would fix this would be valuable. Hoping to get response. - Regards Mahendra <<Snippet of code run >> 4.77496 12.7943 163.695 2.67946 2.18328 2.83959 0.796161 4.77506 12.7946 163.701 2.67946 2.18328 2.83959 0.796157 4.77398 12.7917 163.627 2.67946 2.18328 2.83958 0.796187 4.78219 12.8137 164.19 2.67946 2.18328 2.83958 0.796154 4.78796 12.8291 164.587 2.67946 2.18329 2.8396 0.796033 4.78952 12.8333 164.695 2.67946 2.18329 2.83964 0.795929 4.79168 12.8391 164.842 2.67946 2.18328 2.83959 0.796079 4.79496 12.8479 165.068 2.67946 2.18328 2.83959 0.796217 4.7917 12.8392 164.844 2.67946 2.18328 2.83957 0.796367 4.78888 12.8316 164.65 2.67946 2.18328 2.83957 0.796154 4.78841 12.8303 164.618 2.67946 2.18329 2.8396 0.795824 4.78417 12.819 164.326 2.67946 2.18328 2.83958 0.796221 4.78749 12.8279 164.555 2.67946 2.18328 2.83958 0.796066 4.78355 12.8173 164.284 2.67946 2.18328 2.83959 0.796008 4.78859 12.8308 164.63 2.67946 2.18329 2.8396 0.795986 ==20934== Conditional jump or move depends on uninitialised value(s) ==20934==ÂÂÂ at 0x39BC424031: sqrt (in /lib64/libm-2.5.so) ==20934==ÂÂÂ by 0x345136C7B1: gsl_stats_sd_m (in /usr/lib64/libgsl.so.0.14.0) ==20934==ÂÂÂ by 0x401A31: calc_load_vector_stats (xenloadbalance.c:222) ==20934==ÂÂÂ by 0x401F54: main (xenloadbalance.c:307) ==20934==Â Uninitialised value was created by a stack allocation ==20934==ÂÂÂ at 0x402682: xenstat_get_node (in /var/lib/xen/images/mahendra/
