[Kernel-packages] [Bug 1755999] Re: Reproducible hang in generic/430 with xfstest from upstream
generic/430 still hung on ubuntu 18.04 on azure, kernel version is 5.4.0-1055-azure, file system type is xfs. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1755999 Title: Reproducible hang in generic/430 with xfstest from upstream Status in ubuntu-kernel-tests: Confirmed Status in linux package in Ubuntu: Triaged Status in xfsprogs package in Ubuntu: New Status in linux source package in Bionic: New Status in xfsprogs source package in Bionic: New Bug description: While testing the latest xfstest from upstream, the generic/430 test will hang, no matter using ext4/xfs/btrfs. It looks like this issue was caused by the following command to copy beyond the file: /usr/sbin/xfs_io -i -f -c "copy_range -s 4000 -l 2000 /home/ubuntu/test/test-430/file" "/home/ubuntu/test/test-430/beyond" The copied file will have a correct MD5 as expected. e68d4a150c4e42f4f9ea3ffe4c9cf4ed beyond But the command will never return. The file size of test-430/file is 5000, so a copy_range call with source offset 4000 with length 1000 works, but > 1000 does not. Steps: 1. Deploy a node with Bionic (should have a /dev/sdb available for the test) 2. Run: sudo apt-get install git python-minimal -y git clone --depth=1 https://github.com/Cypresslin/autotest-client-tests.git -b kteam-xfstest-upstream git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest rm -fr autotest/client/tests ln -sf ~/autotest-client-tests autotest/client/tests 3. Run the test with the following command: AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ (The test suite can be built manually, but it's easier to do this with autotest framework) To run this test solely after the test partition has been creation on /dev/sdb: mkdir /home/ubuntu/test cd autotest/client/tmp/xfstests/src/xfstests-bld/xfstests-dev sudo su export TEST_DIR=/home/ubuntu/test export TEST_DEV=/dev/sdb1 ./check generic/430 Tested with the latest mainline kernel, 4.16.0-041600rc5-generic, and the bug still exist.

[Kernel-packages] [Bug 1405807] Re: linux-lts-utopic-tools-common package is empty
** Changed in: linux-lts-utopic (Ubuntu Trusty) Status: Fix Committed = Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-utopic in Ubuntu. https://bugs.launchpad.net/bugs/1405807 Title: linux-lts-utopic-tools-common package is empty Status in linux-lts-utopic package in Ubuntu: Invalid Status in linux-lts-vivid package in Ubuntu: Invalid Status in linux-lts-utopic source package in Trusty: Fix Released Status in linux-lts-vivid source package in Trusty: Fix Committed Bug description: Hi, I installed linux-lts-utopic-tools-common under Ubuntu 14.04.1 and hoped to find the same binaries in it as under Ubuntu utopic, but the package is empty. I guess, do_tools must be set to true somewhere, but I don't know exactly where.
