Summary
Security update for git
Details

This update for git fixes the following issues:

Update from version 2.26.2 to version 2.31.1 (jsc#SLE-18152)

Security fixes:

  • CVE-2021-21300: On case-insensitive file systems with support for symbolic links, if Git is configured globally to apply delay-capable clean/smudge filters (such as Git LFS), Git could run remote code during a clone. (bsc#1183026)

Non security changes:

  • Add sysusers file to create git-daemon user.
  • Remove perl-base and openssh-server dependency on git-coreand provide a perl-Git package. (jsc#SLE-17838)
  • fsmonitor bug fixes
  • Fix git bisect to take an annotated tag as a good/bad endpoint
  • Fix a corner case in git mv on case insensitive systems
  • Require only openssh-clients where possible (like Tumbleweed or SUSE Linux Enterprise >= 15 SP3). (bsc#1183580)
  • Drop rsync requirement, not necessary anymore.
  • Use of pack-redundant command is discouraged and will trigger a warning. The replacement is repack -d.
  • The --format=%(trailers) mechanism gets enhanced to make it easier to design output for machine consumption.
  • No longer give message to choose between rebase or merge upon pull if the history fast-forwards.
  • The configuration variable core.abbrev can be set to no to force no abbreviation regardless of the hash algorithm
  • git rev-parse can be explicitly told to give output as absolute or relative path with the --path-format=(absolute|relative) option.
  • Bash completion update to make it easier for end-users to add completion for their custom git subcommands.
  • git maintenance learned to drive scheduled maintenance on platforms whose native scheduling methods are not 'cron'.
  • After expiring a reflog and making a single commit, the reflog for the branch would record a single entry that knows both @{0} and @{1}, but we failed to answer 'what commit were we on?', i.e. @{1}
  • git bundle learns --stdin option to read its refs from the standard input.
    Also, it now does not lose refs when they point at the same object.
  • git log learned a new --diff-merges=<how> option.
  • git ls-files can and does show multiple entries when the index is unmerged, which is a source for confusion unless -s/-u option is in use. A new option --deduplicate has been introduced.
  • git worktree list now annotates worktrees as prunable, shows locked and prunable attributes in --porcelain mode, and gained a --verbose option.
  • git clone tries to locally check out the branch pointed at by HEAD of the remote repository after it is done, but the protocol did not convey the information necessary to do so when copying an empty repository.
    The protocol v2 learned how to do so.
  • There are other ways than .. for a single token to denote a commit range', namely<rev>^! and<rev>^-<n>, butgit range-diff` did not understand them.
  • The git range-diff command learned --(left|right)-only option to show only one side of the compared range.
  • git mergetool feeds three versions (base, local and remote) of a conflicted path unmodified. The command learned to optionally prepare these files with unconflicted parts already resolved.
  • The .mailmap is documented to be read only from the root level of a working tree, but a stray file in a bare repository also was read by accident, which has been corrected.
  • git maintenance tool learned a new pack-refs maintenance task.
  • Improved error message given when a configuration variable that is expected to have a boolean value.
  • Signed commits and tags now allow verification of objects, whose two object names (one in SHA-1, the other in SHA-256) are both signed.
  • git rev-list command learned --disk-usage option.
  • git diff, git log --{skip,rotate}-to=<path> allows the user to discard diff output for early paths or move them to the end of the output.
  • git difftool learned --skip-to=<path> option to restart an interrupted session from an arbitrary path.
  • git grep has been tweaked to be limited to the sparse checkout paths.
  • git rebase --[no-]fork-point gained a configuration variable rebase.forkPoint so that users do not have to keep specifying a non-default setting.
  • git stash did not work well in a sparsely checked out working tree.
  • Newline characters in the host and path part of git:// URL are now forbidden.
  • Userdiff updates for PHP, Rust, CSS
  • Avoid administrator error leading to data loss with git push --force-with-lease[=<ref>] by introducing --force-if-includes
  • only pull asciidoctor for the default ruby version
  • The --committer-date-is-author-date option of rebase and am subcommands lost the e-mail address by mistake in 2.29
  • The transport protocol v2 has become the default again
  • git worktree gained a repair subcommand, git init --separate-git-dir no longer corrupts administrative data related to linked worktrees
  • git maintenance introduced for repository maintenance tasks
  • fetch.writeCommitGraph is deemed to be still a bit too risky and is no longer part of the feature.experimental set.
  • The commands in the diff family honors the diff.relative configuration variable.
  • git diff-files has been taught to say paths that are marked as intent-to-add are new files, not modified from an empty blob.
  • git gui now allows opening work trees from the start-up dialog.
  • git bugreport reports what shell is in use.
  • Some repositories have commits that record wrong committer timezone; git fast-import has an option to pass these timestamps intact to allow recreating existing repositories as-is.
  • git describe will always use the long version when giving its output based misplaced tags
  • git pull issues a warning message until the pull.rebase configuration variable is explicitly given
