Hello Guilherme, or anyone else affected, Accepted makedumpfile into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/makedumpfile/1:1.6.5-1ubuntu1~18.04.4 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: makedumpfile (Ubuntu Bionic) Status: In Progress => Fix Committed ** Tags added: verification-needed-bionic -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to makedumpfile in Ubuntu. https://bugs.launchpad.net/bugs/1800566 Title: Make reset_devices parameter default for kdump Status in makedumpfile package in Ubuntu: Fix Released Status in makedumpfile source package in Trusty: Won't Fix Status in makedumpfile source package in Xenial: In Progress Status in makedumpfile source package in Bionic: Fix Committed Status in makedumpfile source package in Cosmic: Won't Fix Status in makedumpfile source package in Disco: Won't Fix Status in makedumpfile source package in Eoan: Fix Committed Status in makedumpfile source package in Focal: Fix Released Bug description: [Impact] * Kdump does not configure by default the crash kernel to perform a device reset by default, by passing the "reset_devices" parameter. * Kernel has the "reset_devices" parameter that drivers can opt-in, and perform special activity in case this parameter is parsed from command-line. For example, in kdump kernels it hints the drivers that they are booting from a non-healthy condition and needs to issue some form of reset to the adapter, like clearing DMA mapping in their firmware for example. Users currently (kernel v5.5-rc2) are: aacraid, hpsa, ipr, megaraid_sas, mpt3sas, smartpqi, xenbus. This should be enabled by default in the kdump config file to be added in the kdump kernel command-line for all versions. [Test Case] 1) Deploy a Bionic VM e.g. with uvt-kvm 2) Install the kdump-tools package 3) Run `kdump-config test`and check for the 'reset_devices' parameter: $ kdump-config test ... kexec command to be used: /sbin/kexec -p --command-line="BOOT_IMAGE=/boot/vmlinuz-4.15.0-45-generic root=LABEL=cloudimg-rootfs ro console=tty1 console=ttyS0 nr_cpus=1 systemd.unit=kdump-tools.service irqpoll nousb ata_piix.prefer_ms_hyperv=0" /var/lib/kdump/vmlinuz [Regression Potential] The regression potential is low, since it doesn't need any changes in makedumpfile code and we're only adding a parameter on the crash kernel command-line. The risks are related with bad behavior with the kernel when using "reset_devices", like if the driver has bugs in this path. It's considered safer to have the option (and this way prevent problems for booting a unhealthy kernel with potential stuck DMAs in the devices) than not having it.
