Martin Kletzander	de9ff3efe1	util: Avoid variable named 'truncate' shadowing global declaration ... Signed-off-by: Martin Kletzander <mkletzan@redhat.com>	2015-11-30 15:32:47 +01:00
Pavel Hrdina	cb97426208	virlogd: fix crash if log file exists and it's larger the maxlen ... If for some reason there is an existing log file, that is larger then max length of log file, we need to rollover that file immediately. Trying to figure out how much data we could write will resolve in overflow of unsigned variable 'towrite' and this leads to segfault.

Daniel P. Berrange	910e65d973	util: add APIs for reading/writing from/to rotating files ... Add virRotatingFileReader and virRotatingFileWriter objects which allow reading & writing from/to files with automation rotation to N backup files when a size limit is reached. This is useful for guest logging when a guaranteed finite size limit is required. Use of external tools like logrotate is inadequate since it leaves the possibility for guest to DOS the host in between invokations of logrotate. Signed-off-by: Daniel P.
