Package: release.debian.org
Severity: normal
Tags: bookworm
X-Debbugs-Cc: initramfs-tools@packages.debian.org
Control: affects -1 + src:initramfs-tools
User: release.debian.org@packages.debian.org
Usertags: pu

[ Reason ]
- Fix regressions to copy_file caused by the previous fixes.
- Fix missing reset drivers when using MODULES=dep to reduce the size
  of the initramfs.

[ Impact ]
- Some initramfs-tools hooks stopped working with the previous update
  (bugs #1082647, #1088959).
- Some systems may fail to boot with an initramfs built with
  MODULES=dep (bug #1027458).  The specific example there was a
  Raspberry Pi 4 using USB storage.

[ Tests ]
There are autopkgtest test cases for mkinitramfs.  A new test case has
been added to exercise all the corner cases of copy_file.  All of
these passed in Salsa CI.

[ Risks ]
There could be yet another corner case in copy_file that broke, but
this seems unlikely.

[ Checklist ]
  [X] *all* changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in (old)stable
  [X] the issue is verified as fixed in unstable

commit 37a6e9ecef1a1b6d00a7eeb70bf88e580ef6eb4e
Author: Ben Hutchings <benh@debian.org>

    hook-functions: Expand documentation of copy_exec and copy_file
    
    The documentation is currently a bit vague and doesn't mention
    creation of directories or symlinks at all.  Expand it to describe the
    current behaviour.

    hook-functions: Restore copy_file's handling of target ending in slash
    
    Until recently, copy_file would treat a target ending in a slash as a
    target directory.  This was not intended behaviour, but had worked
    since at least v0.98.8.  It broke when I started using 'realpath' to
    canonicalise the target, which stripped the slash.
    
    Add a specific check for a trailing slash, and document that
    behaviour.

    hook-functions: Exclude usr-merge symlinks in copy_file
    
    Currently if copy_file is invoked as:
    
        copy_file binary /lib/package/command /bin/command
    
    we will end up with:
    
        src=/lib/package/command
        target=/usr/bin/command
        link_target=/usr/lib/package/command
    
    and then we'll copy /lib/package/command to /usr/lib/package/command
    and make /usr/bin/command a symlink to it.  This is not what we used
    to do and not the most sensible behaviour.
    
    mkinitramfs already creates usr-merge symlinks in the initramfs so we
    don't need to worry about creating duplicates when source files are
    named via such symlinks on the host.  So if the host system is
    usr-merged, canonicalise source filenames that use the usr-merge
    symlinks before doing symlink detection.

    autopkgtest: Add tests for copy_file function
    
    As the copy_file is quite complex and has had a number of bugs
    found (and introduced) recently, add an autopkgtest test case that
    exercises most of its functionality and the specific cases where
    bugs were reported.

    [For bookworm, also create ${CONFDIR}/hooks in test-common, which was
     done in upstream commit d75a58bab178.]

    hook-functions: Add reset drivers when MODULES=dep
    
    Reset drivers are currently included when MODULES=most but not when
    MODULES=dep.  Since they are outside the device model, match them by
    module name not by driver class.
