[libvirt] [PATCH 0/2] Implement interface stats for BSD

This series implements support for querying network interface stats on (Free)BSD. It's more of an RFC, because I'm uncertain about few things: - It feels a little strange to have a source file that implements only a single function like this. I am wondering if it would be better to just move it to something like util/virnetdev.c? - FreeBSD stores interface data in the if_data struct and a number of outgoing packet drops is stored in a field 'ifi_oqdrops'. This field was added in -CURRENT and later merged back to 10-STABLE. In order not to break the ABI, it's available only if _IFI_OQDROPS is defined. I've added a configure.ac check which adds -D_IFI_OQDROPS before checking this field and resetting it back if it is not present. This way, this flag will present when the field is available even if the flag is not needed (e.g. on -CURRENT). Is there a better way of doing it? I was thinking about trying to check this field without the flag and if it fails check one more time with the flag, but it looks a little messy. - Did I get it right that the stats reported are from the guest POV, e.g. when downloading a large file from guest, it should look like: vnet0 rx_bytes 731603341 vnet0 rx_packets 518354 vnet0 rx_errs 0 vnet0 rx_drop 0 vnet0 tx_bytes 17577834 vnet0 tx_packets 264226 vnet0 tx_errs 0 vnet0 tx_drop 0 Roman Bogorodskiy (2): util: virstatslinux: make more generic Implement interface stats for BSD configure.ac | 13 ++++- po/POTFILES.in | 2 +- src/Makefile.am | 2 +- src/libvirt_linux.syms | 3 -- src/libvirt_private.syms | 2 + src/lxc/lxc_driver.c | 2 +- src/openvz/openvz_driver.c | 2 +- src/qemu/qemu_driver.c | 16 +----- src/uml/uml_driver.c | 2 +- src/util/{virstatslinux.c => virstats.c} | 93 +++++++++++++++++++++++++------- src/util/{virstatslinux.h => virstats.h} | 12 ++--- src/xen/xen_hypervisor.c | 2 +- tests/statstest.c | 2 +- 13 files changed, 102 insertions(+), 51 deletions(-) rename src/util/{virstatslinux.c => virstats.c} (61%) rename src/util/{virstatslinux.h => virstats.h} (77%) -- 1.9.0
