kbuild: deb-pkg: use build ID instead of debug link for dbg package
There are two ways of managing separate debug info files:
[1] The executable contains the .gnu_debuglink section, which specifies
the name and the CRC of the separate debug info file.
[2] The executable contains a build ID, and the corresponding debug info
file is placed in the .build-id directory.
We could do both, but the former, which 'make deb-pkg' currently does,
results in complicated installation steps because we need to manually
strip the debug sections, create debug links, and re-sign the modules.
Besides, it is not working with module compression.
This commit abandons the approach [1], and instead opts for [2].

Since commit
491b146d4c13 ("kbuild: builddeb: Eliminate debian/arch

dpkg-architecture: error: unknown option 'DEB_HOST_MULTIARCH'
The current code:
dpkg-architecture -a$DEB_HOST_ARCH -qDEB_HOST_MULTIARCH
... does not look sensible because:
- For this code to work correctly, DEB_HOST_ARCH must be pre-defined,
which is true when the packages are built via dpkg-buildpackage.
In this case, DEB_HOST_MULTIARCH is also likely defined, hence there
is no need to query DEB_HOST_MULTIARCH in the first place.
- If DEB_HOST_MULTIARCH is undefined, DEB_HOST_ARCH is likely undefined
too. So, you cannot query DEB_HOST_MULTIARCH in this way. This is
mostly the case where debian/rules is directly executed.
When debian/rules is directly executed, querying DEB_HOST_MUCHARCH is
not enough because we need to know DEB_{BUILD,HOST}_GNU_TYPE as well.
All DEB_* variables are defined when the package build is initiated by
dpkg-buildpackage, but otherwise, let's call dpkg-architecture to set
all DEB_* environment variables.

gen_init_cpio: Apply mtime supplied by user to all file types
Currently gen_init_cpio -d <timestamp> is applied to symlinks,
directories and special files. These files are created by
gen_init_cpio from their description. Without <timestamp> option
current time(NULL) is used. And regular files that go in initramfs
are created before cpio generation, so their mtime(s) are preserved.
This is usually not an issue as reproducible builds should rebuild
everything in the distribution, including binaries, configs and whatever
other regular files may find their way into kernel's initramfs.
On the other hand, gen_initramfs.sh usage claims:
> -d <date> Use date for all file mtime values
Ar Arista initramfs files are managed with version control system
that preserves mtime. Those are configs, boot parameters, init scripts,
version files, platform-specific files, probably some others, too.
While it's certainly possible to work this around by copying the file
into temp directory and adjusting mtime prior to gen_init_cpio call,
I don't see why it needs workarounds.
The intended user of -d <date> option is the one that needs to create
a reproducible build, see commit
a8b8017c34fe ("initramfs: Use
KBUILD_BUILD_TIMESTAMP for generated entries"). If a user wants
the build reproduction, they use -d <date>, which can be set on all
types of files, without surprising exceptions and workarounds.
Let's KISS here and just apply the time that user specified
with -d option.

kbuild: resolve symlinks for O= properly
Currently, Kbuild follows the logical chain of directories for the O=
option, just like 'cd' (or 'realpath --logical') does.
Example:
$ mkdir -p /tmp/a /tmp/x/y
$ ln -s /tmp/x/y /tmp/a/b
$ realpath /tmp/a/b/..
/tmp/x
$ realpath --logical /tmp/a/b/..
/tmp/a
$ make O=/tmp/a/b/.. defconfig
make[1]: Entering directory '/tmp/a'
[snip]
make[1]: Leaving directory '/tmp/a'
'make O=/tmp/a/b/.. defconfig' creates the kernel configuration in
/tmp/a instead of /tmp/x despite /tmp/a/b/.. resolves to /tmp/x.
This is because Kbuild internally uses the 'cd ... && pwd' for the
path resolution, but this behavior is not predictable for users.
Additionally, it is not consistent with how the Kbuild handles the
M= option or GNU Make works with 'make -C /tmp/a/b/..'.
Using the physical directory structure for the O= option seems more
reasonable.
The comment says "expand a shell special character '~'", but it has

To that end, introduce check-uapi.sh: a simple shell script that
checks for changes to UAPI headers using libabigail.
libabigail is "a framework which aims at helping developers and
software distributors to spot some ABI-related issues like interface
incompatibility in ELF shared libraries by performing a static
analysis of the ELF binaries at hand."
The script uses one of libabigail's tools, "abidiff", to compile the
changed header before and after the commit to detect any changes.
abidiff "compares the ABI of two shared libraries in ELF format. It
emits a meaningful report describing the differences between the two
ABIs."
The script also includes the ability to check the compatibility of
all UAPI headers across commits. This allows developers to inspect
the stability of the UAPIs over time.

possible to apply different configs to *.{c,h}, *.py and *.rs.

Although the old cmd_src_tar is still used by snap-pkg, there is no need
to pack and unpack a tarball solely for passing the source to snapcraft.
Instead, you can use 'source-type: local' to tell the source location to
snapcraft.

"Eventfs fixes:
- With the usage of simple_recursive_remove() recommended by Al Viro,
the code should not be calling "d_invalidate()" itself. Doing so is
causing crashes. The code was calling d_invalidate() on the race of
trying to look up a file while the parent was being deleted. This
was detected, and the added dentry was having d_invalidate() called
on it, but the deletion of the directory was also calling
d_invalidate() on that same dentry.
- A fix to not free the eventfs_inode (ei) until the last dput() was
called on its ei->dentry made the ei->dentry exist even after it
was marked for free by setting the ei->is_freed. But code elsewhere
still was checking if ei->dentry was NULL if ei->is_freed is set
and would trigger WARN_ON if that was the case. That's no longer
true and there should not be any warnings when it is true.
- Use GFP_NOFS for allocations done under eventfs_mutex. The
eventfs_mutex can be taken on file system reclaim, make sure that
allocations done under that mutex do not trigger file system
reclaim.
- Clean up code by moving the taking of inode_lock out of the helper
functions and into where they are needed, and not use the parameter
to know to take it or not. It must always be held but some callers
of the helper function have it taken when they were called.
- Warn if the inode_lock is not held in the helper functions.
- Warn if eventfs_start_creating() is called without a parent. As
eventfs is underneath tracefs, all files created will have a parent
(the top one will have a tracefs parent).

Pull vfs fixes from Christian Brauner:
- Avoid calling back into LSMs from vfs_getattr_nosec() calls.
IMA used to query inode properties accessing raw inode fields without
dedicated helpers. That was finally fixed a few releases ago by
forcing IMA to use vfs_getattr_nosec() helpers.
The goal of the vfs_getattr_nosec() helper is to query for attributes
without calling into the LSM layer which would be quite problematic
because incredibly IMA is called from __fput()...
__fput()
-> ima_file_free()
What it does is to call back into the filesystem to update the file's
IMA xattr. Querying the inode without using vfs_getattr_nosec() meant
that IMA didn't handle stacking filesystems such as overlayfs
correctly. So the switch to vfs_getattr_nosec() is quite correct. But
the switch to vfs_getattr_nosec() revealed another bug when used on
stacking filesystems:
__fput()
-> ima_file_free()
-> vfs_getattr_nosec()
-> i_op->getattr::ovl_getattr()
-> vfs_getattr()
-> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
-> security_inode_getattr() # calls back into LSMs
Now, if that __fput() happens from task_work_run() of an exiting task
current->fs and various other pointer could already be NULL. So
anything in the LSM layer relying on that not being NULL would be
quite surprised.
Fix that by passing the information that this is a security request
through to the stacking filesystem by adding a new internal
ATT_GETATTR_NOSEC flag. Now the callchain becomes:
__fput()
-> ima_file_free()
-> vfs_getattr_nosec()
-> i_op->getattr::ovl_getattr()
-> if (AT_GETATTR_NOSEC)
vfs_getattr_nosec()
else
vfs_getattr()
-> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr()
- Fix a bug introduced with the iov_iter rework from last cycle.
This broke /proc/kcore by copying too much and without the correct
offset.
- Add a missing NULL check when allocating the root inode in
autofs_fill_super().
- Fix stable writes for multi-device filesystems (xfs, btrfs etc) and
the block device pseudo filesystem.
Stable writes used to be a superblock flag only, making it a per
filesystem property. Add an additional AS_STABLE_WRITES mapping flag
to allow for fine-grained control.
- Ensure that offset_iterate_dir() returns 0 after reaching the end of
a directory so it adheres to getdents() convention.

AFS doesn't really do locking on R/O volumes as fileservers don't maintain
state with each other and thus a lock on a R/O volume file on one
fileserver will not be be visible to someone looking at the same file on
another fileserver.
Further, the server may return an error if you try it.
Fix this by doing what other AFS clients do and handle filelocking on R/O
volume files entirely within the client and don't touch the server.

That would mean @size == 0, at which point size_to_bucket() returns -1
and the above happens.
alloc_chain_hlocks() has 'size - req', for the first with the
precondition 'size >= rq', which allows the 0.
This code is trying to split a block, del_chain_block() takes what we
need, and add_chain_block() puts back the remainder, except in the
above case the remainder is 0 sized and things go sideways.
