Subject: bootconfig: Fix negative seeks on 32-bit with LFS enabled
Forwarded: https://lore.kernel.org/linux-trace-kernel/aKHlevxeg6Y7UQrz@decadent.org.uk/T/
Commit 26dda5769509 "tools/bootconfig: Cleanup bootconfig footer size
calculations" replaced some expressions of type int with the
BOOTCONFIG_FOOTER_SIZE macro, which expands to an expression of type
size_t, which is unsigned.
On 32-bit architectures with LFS enabled (i.e. off_t is 64-bit), the
seek offset of -BOOTCONFIG_FOOTER_SIZE now turns into a positive
value.
Fix this by casting the size to off_t before negating it.
Just in case someone changes BOOTCONFIG_MAGIC_LEN to have type size_t
later, do the same thing to the seek offset of -BOOTCONFIG_MAGIC_LEN.

Subject: bootconfig: Fix unaligned access when building footer
Forwarded: https://lore.kernel.org/linux-trace-kernel/aIC-NTw-cdm9ZGFw@decadent.org.uk/T/
Currently we add padding between the bootconfig text and footer to
ensure that the footer is aligned within the initramfs image.
However, because only the bootconfig data is held in memory, not the
full initramfs image, the footer may not be naturally aligned in
memory.
This can result in an alignment fault (SIGBUS) when writing the footer
on some architectures, such as sparc.
Build the footer in a struct on the stack before adding it to the
buffer.

Subject: ext4: don't try to clear the orphan_present feature block device is
r/o
Origin: https://git.kernel.org/linus/c5e104a91e7b6fa12c1dc2d8bf84abb7ef9b89ad
Bug-Debian: https://bugs.debian.org/1108271
When the file system is frozen in preparation for taking an LVM
snapshot, the journal is checkpointed and if the orphan_file feature
is enabled, and the orphan file is empty, we clear the orphan_present
feature flag. But if there are pending inodes that need to be removed
the orphan_present feature flag can't be cleared.
The problem comes if the block device is read-only. In that case, we
can't process the orphan inode list, so it is skipped in
ext4_orphan_cleanup(). But then in ext4_mark_recovery_complete(),
this results in the ext4 error "Orphan file not empty on read-only fs"
firing and the file system mount is aborted.
Fix this by clearing the needs_recovery flag in the block device is
read-only. We do this after the call to ext4_load_and_init-journal()
since there are some error checks need to be done in case the journal
needs to be replayed and the block device is read-only, or if the
block device containing the externa journal is read-only, etc.

There are many same pattern of 8 + BOOTCONFIG_MAGIC_LEN for calculating
the size of bootconfig footer. Use BOOTCONFIG_FOOTER_SIZE macro to
clean up those magic numbers.
