Azure: Add netplan driver filter when using hv_netvsc driver (#539)

2020-08-25T03:48:21+00:00

This fixes a long delay during boot of some instances. For Azure instance types using SR-IOV via the Hyper-V netvsc network driver, two network interfaces are created that share the same MAC, but only the virtual device should be configured and used. Updating the netplan configuration to filter on the hv_netvsc driver prevents netplan from trying to figure both devices. LP: #1830740

DHCP sandboxing failing on noexec mounted /var/tmp (#521)

2020-08-24T13:34:24+00:00

* DHCP sandboxing failing on noexec mounted /var/tmp If /var/tmp is mounted with noexec option the DHCP sandboxing will fail with Permission Denied. This patch simply avoids this error by checking the exec permission updating the dhcp path in negative case. rhbz: https://bugzilla.redhat.com/show_bug.cgi?id=1857309 Signed-off-by: Eduardo Otubo * Replacing with os.* calls * Adding test and removing isfile() useless call.

Update the list of valid ssh keys. (#487)

2020-08-21T16:23:24+00:00

Update ssh_util.py with latest list of keys (from openssh-8.3p1/sshkey.c), Added keys: sk-ecdsa-sha2-nistp256-cert-v01@openssh.com sk-ecdsa-sha2-nistp256@openssh.com sk-ssh-ed25519-cert-v01@openssh.com sk-ssh-ed25519@openssh.com ssh-xmss-cert-v01@openssh.com ssh-xmss@openssh.com LP: #1877869

cmd: cloud-init query to handle compressed userdata (#516)

2020-08-20T21:51:35+00:00

cloud-init query tries to directly load and decode raw user-data from /var/lib/cloud/instance/user-data.txt. This results in UnicodeDecodeErrors on some platforms which provide compressed content. Avoid UnicodeDecoderErrors when parsing compressed user-data at /var/lib/cloud/instance/user-data.txt. LP: #1889938

Pushing cloud-init log to the KVP (#529)

2020-08-20T19:04:03+00:00

Push the cloud-init.log file (Up to 500KB at once) to the KVP before reporting ready to the Azure platform. Based on the analysis done on a large sample of cloud-init.log files, Here's the statistics collected on the log file size: P50 P90 P95 P99 P99.9 P99.99 137K 423K 537K 3.5MB 6MB 16MB This change limits the size of cloud-init.log file data that gets dumped to KVP to 500KB. So for ~95% of the cases, the whole log file will be dumped and for the remaining ~5%, we will get the last 500KB of the cloud-init.log file. To asses the performance of the 500KB limit, 250 VM were deployed with a 500KB cloud-init.log file and the time taken to compress, encode and dump the entries to KVP was measured. Here's the time in milliseconds percentiles: P50 P99 P999 75.705 232.701 1169.636 Another 250 VMs were deployed with this logic dumping their normal cloud-init.log file to KVP, the same timing was measured as above. Here's the time in milliseconds percentiles: P50 P99 P999 1.88 5.277 6.992 Added excluded_handlers to the report_event function to be able to opt-out from reporting the events of the compressed cloud-init.log file to the cloud-init.log file. The KVP break_down logic had a bug, where it will reuse the same key for all the split chunks of KVP which results in overwriting the split KVPs by the last one when consumed by Hyper-V. I added the split chunk index as a differentiator to the KVP key. The Hyper-V consumes the KVPs from the KVP file as chunks whose key is 512KB and value is 2048KB but the Azure platform expects the value to be 1024KB, thus I introduced the Azure value limit.

Add Alpine Linux support. (#535)

2020-08-19T23:18:25+00:00

Add new module cc_apk_configure for creating Alpine /etc/apk/repositories file. Modify cc_ca_certs, cc_ntp, cc_power_state_change, and cc_resolv_conf for Alpine. Add Alpine template files for Chrony and Busybox NTP support. Add Alpine template file for /etc/hosts.

Detect kernel version before swap file creation (#428)

2020-08-18T21:12:02+00:00

According to man page `man 8 swapon', "Preallocated swap files are supported on XFS since Linux 4.18". This patch checks for kernel version before attepting to create swapfile, using dd for XFS only on kernel versions <= 4.18 or btrfs. Add new func util.kernel_version which returns a tuple of ints (major, minor) Signed-off-by: Eduardo Otubo otubo@redhat.com
