Canonical Outs Important Linux Kernel Security Update for All Ubuntu Releases

Tuesday 18th of June 2019 09:01:00 PM
Canonical has released an important Linux kernel security update for all supported Ubuntu Linux releases to address two critical security vulnerabilities that could crash users' systems.

In a recent security advisory, Canonical details two recently discovered security vulnerabilities (CVE-2019-11477 and CVE-2019-11478) affecting Linux kernel's TCP retransmission queue implementation when handling some specific TCP Selective Acknowledgment (SACKs). 

Both security vulnerabilities were discovered by Jonathan Looney and could allow a remote attacker to crash the affected systems by causing a denial of service. Known as SACK Panic, they affect all supported Ubuntu Linux releases, including Ubuntu 19.04, Ubuntu 18.10, Ubuntu 18.04 LTS, and Ubuntu 16.04 LTS.

"Jonathan Looney discovered several flaws in the way that ... (read more)

Canonical Will Drop Support for 32-bit Architectures in Future Ubuntu Releases

Tuesday 18th of June 2019 08:21:00 PM
Canonical announced today that it finally decided to completely drop support for 32-bit (i386) hardware architectures in future releases of its popular Ubuntu Linux operating system.

Last year, during the development cycle of the Ubuntu 18.04 LTS (Bionic Beaver) operating system series, Canonical announced that they won't offer 32-bit installation images (ISOs), a trend that was shortly followed by all official Ubuntu Linux flavors with the Ubuntu 18.10 (Cosmic Cuttlefish) release. However, Ubuntu's 32-bit repositories were still available.

As Ubuntu 18.04 LTS (Bionic Beaver) will be supported for the next five years, Canonical disabled upgrades from Ubuntu 18.04 LTS to Ubuntu 18.10 for 32-bit systems to avoid leaving users on a short-lived release, and now, they announced that starting with the upcoming Ubuntu 19.10 (Eoan Ermine) release, support for 32-bit system will no longer be provided.

"The Ubuntu engineering team has reviewed the facts before us and conclu... (read more)

Microsoft Edge for Linux: A Browser the Software Giant “Would Like to Do”

Friday 14th of June 2019 07:36:00 AM
Microsoft announced in late 2018 that it’d switch Edge browser to the Chromium engine, the same one that’s being used by Google Chrome.

This decision technically allows Microsoft to convert Microsoft Edge from a Windows 10-exclusive browser to a cross-platform application.

The company has already confirmed Microsoft Edge would be released beyond Windows 10, and existing preview builds also allow the browser to be installed on macOS.

The migration to Chromium would technically allow the company to bring Edge to Linux as well, and given its efforts to get more involved in the open-source world, such a release wouldn’t be surprising at all.

Linux version possible in the long term

And after Microsoft suggested that it’s indeed considering a Linux version of Edge back in May at the Build developer conference, the Edge tea... (read more)

Linux Kernel 5.0 Reaches End of Life, Users Urged to Upgrade to Linux Kernel 5.1

Tuesday 4th of June 2019 01:10:00 PM
Linux kernel developer Greg Kroah-Hartman announced today that the Linux 5.0 kernel series reached end of life, urging users to upgrade to the most recent stable series.

Released two months ago, on March 4th, 2019, by Linus Torvalds, the Linux 5.0 kernel series was long anticipated by the Linux community, but it was only the version number that was a major thing, as Linux kernel 5.0 didn't brought any major changes, nor it was a long-term support release.

Linux kernel 5.0.21 was released today as the last maintenance update for the Linux 5.0 kernel series, which means that no further updates or security patches will be provided for it. Therefore, users are urged to upgrade to the latest Linux 5.1 kernel series as soon as possible.

"I'm announcing the release of the 5.0.21 kernel. All users of the 5.0 kernel series must upgrade," said G... (read more)

    Git 2.23 Release Notes
    ======================
    
    Updates since v2.22
    -------------------
    
    Backward compatibility note
    
     * The "--base" option of "format-patch" computed the patch-ids for
       prerequisite patches in an unstable way, which has been updated to
       compute in a way that is compatible with "git patch-id --stable".
    
     * The "git log" command by default behaves as if the --mailmap option
       was given.
    
    
    UI, Workflows & Features
    
     * The "git fast-export/import" pair has been taught to handle commits
       with log messages in encoding other than UTF-8 better.
    
     * In recent versions of Git, per-worktree refs are exposed in
       refs/worktrees// hierarchy, which means that worktree names
       must be a valid refname component.  The code now sanitizes the names
       given to worktrees, to make sure these refs are well-formed.
    
     * "git merge" learned "--quit" option that cleans up the in-progress
       merge while leaving the working tree and the index still in a mess.
    
     * "git format-patch" learns a configuration to set the default for
       its --notes= option.
    
     * The code to show args with potential typo that cannot be
       interpreted as a commit-ish has been improved.
    
     * "git clone --recurse-submodules" learned to set up the submodules
       to ignore commit object names recorded in the superproject gitlink
       and instead use the commits that happen to be at the tip of the
       remote-tracking branches from the get-go, by passing the new
       "--remote-submodules" option.
    
     * The pattern "git diff/grep" use to extract funcname and words
       boundary for Matlab has been extend to cover Octave, which is more
       or less equivalent.
    
     * "git help git" was hard to discover (well, at least for some
       people).
    
     * The pattern "git diff/grep" use to extract funcname and words
       boundary for Rust has been added.
    
     * "git status" can be told a non-standard default value for the
       "--[no-]ahead-behind" option with a new configuration variable
       status.aheadBehind.
    
     * "git fetch" and "git pull" reports when a fetch results in
       non-fast-forward updates to let the user notice unusual situation.
       The commands learned "--no-show-forced-updates" option to disable
       this safety feature.
    
     * Two new commands "git switch" and "git restore" are introduced to
       split "checking out a branch to work on advancing its history" and
       "checking out paths out of the index and/or a tree-ish to work on
       advancing the current history" out of the single "git checkout"
       command.
    
     * "git branch --list" learned to always output the detached HEAD as
       the first item (when the HEAD is detached, of course), regardless
       of the locale.
    
     * The conditional inclusion mechanism learned to base the choice on
       the branch the HEAD currently is on.
    
     * "git rev-list --objects" learned the "--no-object-names" option to
       squelch the path to the object that is used as a grouping hint for
       pack-objects.
    
     * A new tag.gpgSign configuration variable turns "git tag -a" into
       "git tag -s".
    
     * "git multi-pack-index" learned expire and repack subcommands.
    
     * "git blame" learned to "ignore" commits in the history, whose
       effects (as well as their presence) get ignored.
    
     * "git cherry-pick/revert" learned a new "--skip" action.
    
     * The tips of refs from the alternate object store can be used as
       starting point for reachability computation now.
    
     * Extra blank lines in "git status" output have been reduced.
    
     * The commits in a repository can be described by multiple
       commit-graph files now, which allows the commit-graph files to be
       updated incrementally.
    
     * "git range-diff" output has been tweaked for easier identification
       of which part of what file the patch shown is about.
    
    
    Performance, Internal Implementation, Development Support etc.
    
     * Update supporting parts of "git rebase" to remove code that should
       no longer be used.
    
     * Developer support to emulate unsatisfied prerequisites in tests to
       ensure that the remainder of the tests still succeeds when tests
       with prerequisites are skipped.
    
     * "git update-server-info" learned not to rewrite the file with the
       same contents.
    
     * The way of specifying the path to find dynamic libraries at runtime
       has been simplified.  The old default to pass -R/path/to/dir has been
       replaced with the new default to pass -Wl,-rpath,/path/to/dir,
       which is the more recent GCC uses.  Those who need to build with an
       old GCC can still use "CC_LD_DYNPATH=-R"
    
     * Prepare use of reachability index in topological walker that works
       on a range (A..B).
    
     * A new tutorial targeting specifically aspiring git-core
       developers has been added.
    
     * Auto-detect how to tell HP-UX aCC where to use dynamically linked
       libraries from at runtime.
    
     * "git mergetool" and its tests now spawn fewer subprocesses.
    
     * Dev support update to help tracing out tests.
    
     * Support to build with MSVC has been updated.
    
     * "git fetch" that grabs from a group of remotes learned to run the
       auto-gc only once at the very end.
    
     * A handful of Windows build patches have been upstreamed.
    
     * The code to read state files used by the sequencer machinery for
       "git status" has been made more robust against a corrupt or stale
       state files.
    
     * "git for-each-ref" with multiple patterns have been optimized.
    
     * The tree-walk API learned to pass an in-core repository
       instance throughout more codepaths.
    
     * When one step in multi step cherry-pick or revert is reset or
       committed, the command line prompt script failed to notice the
       current status, which has been improved.
    
     * Many GIT_TEST_* environment variables control various aspects of
       how our tests are run, but a few followed "non-empty is true, empty
       or unset is false" while others followed the usual "there are a few
       ways to spell true, like yes, on, etc., and also ways to spell
       false, like no, off, etc." convention.
    
     * Adjust the dir-iterator API and apply it to the local clone
       optimization codepath.
    
     * We have been trying out a few language features outside c89; the
       coding guidelines document did not talk about them and instead had
       a blanket ban against them.
    
     * A test helper has been introduced to optimize preparation of test
       repositories with many simple commits, and a handful of test
       scripts have been updated to use it.
    
    
    Fixes since v2.22
    -----------------
    
     * A relative pathname given to "git init --template= "
       ought to be relative to the directory "git init" gets invoked in,
       but it instead was made relative to the repository, which has been
       corrected.
    
     * "git worktree add" used to fail when another worktree connected to
       the same repository was corrupt, which has been corrected.
    
     * The ownership rule for the file descriptor to fast-import remote
       backend was mixed up, leading to an unrelated file descriptor getting
       closed, which has been fixed.
    
     * A "merge -c" instruction during "git rebase --rebase-merges" should
       give the user a chance to edit the log message, even when there is
       otherwise no need to create a new merge and replace the existing
       one (i.e. fast-forward instead), but did not.  Which has been
       corrected.
    
     * Code cleanup and futureproof.
    
     * More parameter validation.
    
     * "git update-server-info" used to leave stale packfiles in its
       output, which has been corrected.
    
     * The server side support for "git fetch" used to show incorrect
       value for the HEAD symbolic ref when the namespace feature is in
       use, which has been corrected.
    
     * "git am -i --resolved" segfaulted after trying to see a commit as
       if it were a tree, which has been corrected.
    
     * "git bundle verify" needs to see if prerequisite objects exist in
       the receiving repository, but the command did not check if we are
       in a repository upfront, which has been corrected.
    
     * "git merge --squash" is designed to update the working tree and the
       index without creating the commit, and this cannot be countermanded
       by adding the "--commit" option; the command now refuses to work
       when both options are given.
    
     * The data collected by fsmonitor was not properly written back to
       the on-disk index file, breaking t7519 tests occasionally, which
       has been corrected.
    
     * Update to Unicode 12.1 width table.
    
     * The command line to invoke a "git cat-file" command from inside
       "git p4" was not properly quoted to protect a caret and running a
       broken command on Windows, which has been corrected.
    
     * "git request-pull" learned to warn when the ref we ask them to pull
       from in the local repository and in the published repository are
       different.
    
     * When creating a partial clone, the object filtering criteria is
       recorded for the origin of the clone, but this incorrectly used a
       hardcoded name "origin" to name that remote; it has been corrected
       to honor the "--origin " option.
    
     * "git fetch" into a lazy clone forgot to fetch base objects that are
       necessary to complete delta in a thin packfile, which has been
       corrected.
    
     * The filter_data used in the list-objects-filter (which manages a
       lazily sparse clone repository) did not use the dynamic array API
       correctly---'nr' is supposed to point at one past the last element
       of the array in use.  This has been corrected.
    
     * The description about slashes in gitignore patterns (used to
       indicate things like "anchored to this level only" and "only
       matches directories") has been revamped.
    
     * The URL decoding code has been updated to avoid going past the end
       of the string while parsing %-- sequence.
    
     * The list of for-each like macros used by clang-format has been
       updated.
    
     * "git branch --list" learned to show branches that are checked out
       in other worktrees connected to the same repository prefixed with
       '+', similar to the way the currently checked out branch is shown
       with '*' in front.
       (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint).
    
     * Code restructuring during 2.20 period broke fetching tags via
       "import" based transports.
    
     * The commit-graph file is now part of the "files that the runtime
       may keep open file descriptors on, all of which would need to be
       closed when done with the object store", and the file descriptor to
       an existing commit-graph file now is closed before "gc" finalizes a
       new instance to replace it.
    
     * "git checkout -p" needs to selectively apply a patch in reverse,
       which did not work well.
    
     * Code clean-up to avoid signed integer wraparounds during binary search.
    
     * "git interpret-trailers" always treated '#' as the comment
       character, regardless of core.commentChar setting, which has been
       corrected.
    
     * "git stash show 23" used to work, but no more after getting
       rewritten in C; this regression has been corrected.
    
     * "git rebase --abort" used to leave refs/rewritten/ when concluding
       "git rebase -r", which has been corrected.
    
     * An incorrect list of options was cached after command line
       completion failed (e.g. trying to complete a command that requires
       a repository outside one), which has been corrected.
    
     * The code to parse scaled numbers out of configuration files has
       been made more robust and also easier to follow.
    
     * The codepath to compute delta islands used to spew progress output
       without giving the callers any way to squelch it, which has been
       fixed.
    
     * Protocol capabilities that go over wire should never be translated,
       but it was incorrectly marked for translation, which has been
       corrected.  The output of protocol capabilities for debugging has
       been tweaked a bit.
    
     * Use "Erase in Line" CSI sequence that is already used in the editor
       support to clear cruft in the progress output.
    
     * "git submodule foreach" did not protect command line options passed
       to the command to be run in each submodule correctly, when the
       "--recursive" option was in use.
    
     * The configuration variable rebase.rescheduleFailedExec should be
       effective only while running an interactive rebase and should not
       affect anything when running a non-interactive one, which was not
       the case.  This has been corrected.
    
     * The "git clone" documentation refers to command line options in its
       description in the short form; they have been replaced with long
       forms to make them more recognisable.
    
     * Generation of pack bitmaps are now disabled when .keep files exist,
       as these are mutually exclusive features.
       (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).
    
     * "git rm" to resolve a conflicted path leaked an internal message
       "needs merge" before actually removing the path, which was
       confusing.  This has been corrected.
    
     * "git stash --keep-index" did not work correctly on paths that have
       been removed, which has been fixed.
       (merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint).
    
     * Window 7 update ;-)
    
     * A codepath that reads from GPG for signed object verification read
       past the end of allocated buffer, which has been fixed.
    
     * "git clean" silently skipped a path when it cannot lstat() it; now
       it gives a warning.
    
     * "git push --atomic" that goes over the transport-helper (namely,
       the smart http transport) failed to prevent refs to be pushed when
       it can locally tell that one of the ref update will fail without
       having to consult the other end, which has been corrected.
    
     * The internal diff machinery can be made to read out of bounds while
       looking for --function-context line in a corner case, which has been
       corrected.
       (merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint).
    
     * Other code cleanup, docfix, build fix, etc.
       (merge fbec05c210 cc/test-oidmap later to maint).
       (merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint).
       (merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint).

Games: Mutant Year Zero Road To Eden and Unigine 2.9

Linux 5.4 To Expose What's Keeping The System Awake Via Sysfs

The next Linux kernel version will expose the real-time sources of what's keeping the system awake via Sysfs compared to existing source information that previously was only available via DebugFS. With Linux 5.4, wakeup source statistics will now be exposed under /sys/class/wakeup/wakeup*/ for tracking wakeups, their counts, and related bits for profiling the system for power usage optimizations. Suspend-blocking wakeup sources have been available under DebugFS to be useful for bug reporting and analyzing battery consumption. This solidifies the work now under Sysfs with a stable ABI. In addition to the interfaces now stable in adding them to sysfs, it makes them more accessible compared to DebugFS often being restricted to root or other restrictions in place by different distribution kernels.
