The most apparent issue fixed by this series is the one from 3/6: with a log file configured, we wouldn't print to standard error anymore, during initialisation, which means that users such as libvirt lost the ability to report meaningful error messages that occurred during initialisation, in that case. Stefano Brivio (6): conf, passt: Don't try to log to stderr after we close it conf, log: Introduce internal log flags, instead of abusing log levels log, passt: Always print to stderr before initialisation is complete log: Add _perror() logging function variants treewide: Replace perror() calls with calls to logging functions treewide: Replace strerror() calls arch.c | 10 ++++---- conf.c | 45 ++++++++++++++++++---------------- fwd.c | 2 +- isolation.c | 46 +++++++++++++++-------------------- log.c | 57 +++++++++++++++++++++++++++++++------------ log.h | 26 +++++++++++++++++--- netlink.c | 4 +-- passt.1 | 3 ++- passt.c | 70 +++++++++++++++++++++++------------------------------ pasta.c | 41 +++++++++++++++---------------- pcap.c | 8 +++--- tap.c | 14 +++++------ tcp.c | 24 ++++++------------ util.c | 12 ++++----- 14 files changed, 189 insertions(+), 173 deletions(-) -- 2.43.0
