* [archive] make FileCacheArchive methods re-entrantBryn M. Reeves2018-06-182-74/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since plugins are now run concurrently the Archive class must be re-entrant: different plugins may attempt to create the same paths in the archive, and since they are executing in parallel and with no locking, there exists a TOCTOU race between the use of os.path.{exists,isdir, etc.}() and the subsequent creation of a new path. Address this by implementing a simple monitor-style locking scheme for the FileCacheArchive class. A `_path_lock` member is added to the class and this must be held across any operation that modifies the namespace of the archive (including file, directory, symlink, and special node creation). Additionally, the `_check_path()` Archive method (which checks for the existence of path components up to the basename of the file, creating directories as required) is extended to also carry out a test for the existence of the path, and if the path does exist, that the object is of the expected type. A mismatch in the object type generates a ValueError with an appropriate string description of the problem. Benchmarking shows a consistent small improvement with the patch: this is a result of reduced redundant copy operations that the previous archive structure allowed (since duplicate operations are now aborted as soon as the _path_lock is acquired).

* netplan conf files can exist in 3 locationsEric Desrochers2018-06-071-0/+2
| | | | | | | | | | | | | | | | | Configuration files can exist in three different locations with the precedence from most important to least as follows: /run/netplan/*.yaml /etc/netplan/*.yaml /lib/netplan/*.yaml Alphabetically later files, no matter what directory in, will amend keys if the key does not already exist and override previous keys if they do.

* [Ubuntu] Add ubuntu-advantage status, u-s-s to better default and hweBryan Quigley2018-06-071-12/+5
| | | | | | | | | | | | | | | | | Add ubuntu-advantage status which is installed by default on Ubuntu and shows when various UA items are enabled - esm, fips, and livepatch. Switch ubuntu-support-status to always --show-all. It takes exactly the same amount of time to run (in both cases it's relatively slow at 3 seconds), and only adds 30k uncompressed/12k compressed. Add hwe-support-status to give more details about Ubuntu Hardware enablement if present. Resolves: #1330 Signed-off-by: Bryan Quigley <bryan.quigley@canonical.com> Signed-off-by: Bryn M.

* [archive] switch compression preset from -1 to -2Bryan Quigley2018-06-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've noted an uptick of users recompressing sosreports to get a better compression rate for uploading over slow links. My tests indicate that -2 is a better default and should remove any benefit of compressing again. In tested cases -2 does not cause any significant CPU increase and always has shown an improvment - sometimes substancial. The worst was 3seconds more for a 15MB savings. I would generally expect to see similar percentage savings as sosreports get bigger. -3 and higher were evaluated but had diminshing returns that didn't seem worth it. Tests results: NVMe drive xz -a --batch -1 5.9M 30.766s -2 5.7M 30.673s -3 5.6M 30.101s -4 5.5M 35.882s bz2 bz2 -a --batch -1 11M 36.675s -2 8.3M 38.792s xz -a --all-logs --batch -1 87M 1m8.994s -2 72M 1m11.926s -3 69M 1m18.210s -4 70M 2m33.930s Old hard drive -a --batch -1 5.3M 14.935s -2 5.2M 15.611s -a --batch --all-logs -1 35M 38.881s -2 26M 38.337s Resolves: #1307 Signed-off-by: Bryan Quigley <bryan.quigley@canonical.com> Signed-off-by: Bryn M.

* [filesys] Add permission and selinux check for /tmpJake Hunsaker2018-06-071-1/+8
| | | | | | | | | | | | | | | | Adds a check for the /tmp directory for permissions and selinux context. If either of these are incorrect, the system in question can exhibit strange behavior and otherwise be difficult for support teams to detect. On systems where SELinux is disabled, the permission check is still relevant and the command still produces useful output with the -Z option.

* [docker] Simplify command buildingJake Hunsaker2018-06-071-29/+11
| | | | | | | | | | An early change to the docker plugin corrected the Debian/Ubuntu docker command to be "docker" instead of "docker.io". This means that the docker commands run by the plugin are not going to be different across distributions. As such, the way the commands are built by the plugin have been simplified to ease readability. Signed-off-by: Jake Hunsaker <jhunsake@redhat.com>

* [Plugin] Do not run verify on empty package listJake Hunsaker2018-06-071-1/+5
| | | | | | | | | | | | | | | In some instances, the regex match in all_pkgs_by_name_regex() was returning an empty list when no match was made. This in turn caused sos to run an empty verify command, e.g. 'rpm -V '. By filtering the list of packages to verify, we can remove these empty lists and avoid the empty verify command.

* [kernel] Avoid capturing blanket 'find -ls'Jake Hunsaker2018-06-061-2/+4
| | | | | | | | | | | | | | | | | | | | | | Previously, if sos was run in an environment where '/lib/modules/*' did not exist, the kernel plugin would pass an empty extra_mod_paths list to 'find -ls', which would in turn cause sos to execute 'find -ls' on the entire filesystem. While this situation may seem rare, this is a possiblity whenever sos is run in a container that does not have the proper environment variable set that indicates to the active policy that sos is in fact in a container. On top of generating a sosreport with little to useful information in this case, the generated sosreport could potentially be very large due to the collection of a blanket 'find -ls'. This prevents this from occuring, by not running 'find -ls' if the extra_mod_paths list is empty. Resolves: #1288 Signed-off-by: Jake Hunsaker <jhunsake@redhat.com> Signed-off-by: Bryn M.

* [sosreport] Concurrently run pluginsJake Hunsaker2018-06-066-27/+100
| | | | | | | | | | | | | | | | | | | | | Changes sos to run plugins concurrently. By default sos will now use four (4) threads to run plugins, allowing for faster overall execution of sosreport. The number of threads can be changed using the --threads commandline option. Plugins now also have a timeout applied to them as a whole to avoid situations where sosreport appears to be hung. If a plugin exceeds the timeout threshold, the plugin will be terminated immediately. - this allows sos to not only continue running normally, but should still allow for collection of commands run by the plugin up until it was terminated. The timeout is plugin controlled, and defaults to 300 seconds if not set. Note that for python2 environments, this adds a dependency on python-futures. The futures module is present in the standard library for python3 environments. Signed-off-by: Jake Hunsaker <jhunsake@redhat.com>
* [utilities] Allow size limits for command outputJake Hunsaker2018-05-292-17/+83
| | | | | | | | | | | | | | | | | | | | | | | Previously, any command output generated from plugins from add_cmd_output and add_journal would be collected in full in memory. For example, if a journal was 4GB in size, then 4GB would be read into memory and subsequently written to the final sos archive. This lead to not only potentially large archives, but in some cases failure to collect data or produce an archive due to memory constraints on the system. This patch adds the ability to use a sizelimit option in both add_cmd_output and add_journal. This will limit the collected output from commands or journals to the given limit, both what is read into memory and what is written to the final archive. If not given, sizelimit will default to --log-size. For journal collection, if no sizelimit is given then the larger of either --log-size or 100mb is used.
