The relationship between subtests and test cases is somewhat
confusing, so let's do away with the notion of sub-tests and switch to
just working with some number of test cases. Add a
test_suite__for_each_test_case as in many cases, except the special
one test case situation, the iteration can just be on all test
cases. Switch variable names to be more intention revealing of what
their value is.
This work was motivated by discussion with Kan where it was noted the
code is becoming overly indented:
https://lore.kernel.org/lkml/20241109160219.49976-1-irogers@google.com/
Unifying more of the sub-test/no-sub-tests avoids one level of
indentation in a number of places.

Problem: The x86_64 UEFI doc references Elilo which is an
unmaintained/orphaned bootloader project. Also, on x86_64 a bootloader
is technically not actually required since there is support for the
Linux EFI stub.
Solution: Remove the references to Elilo from the doc and refer to the
EFI stub doc page, update steps accordingly, and add more details about
creation of the EFI partition to improve clarity.

pcie_read_tlp_log() handles only 4 Header Log DWORDs but TLP Prefix Log
(PCIe r6.1 secs 7.8.4.12 & 7.9.14.13) may also be present.
Generalize pcie_read_tlp_log() and struct pcie_tlp_log to also handle TLP
Prefix Log. The relevant registers are formatted identically in AER and DPC
Capability, but has these variations:
a) The offsets of TLP Prefix Log registers vary.
b) DPC RP PIO TLP Prefix Log register can be < 4 DWORDs.
c) AER TLP Prefix Log Present (PCIe r6.1 sec 7.8.4.7) can indicate Prefix
Log is not present.
Therefore callers must pass the offset of the TLP Prefix Log register and
the entire length to pcie_read_tlp_log() to be able to read the correct
number of TLP Prefix DWORDs from the correct offset.

UBSAN detects that inline_xattr_addr() tries to access .i_addr[-1125].
w/ below testcase, it can reproduce this bug easily:
- mkfs.f2fs -f -O extra_attr,flexible_inline_xattr /dev/sdb
- mount -o inline_xattr_size=512 /dev/sdb /mnt/f2fs
- touch /mnt/f2fs/file
- umount /mnt/f2fs
- inject.f2fs --node --mb i_inline --nid 4 --val 0x1 /dev/sdb
- inject.f2fs --node --mb i_inline_xattr_size --nid 4 --val 2048 /dev/sdb
- mount /dev/sdb /mnt/f2fs
- getfattr /mnt/f2fs/file
The root cause is if metadata of filesystem and inode were fuzzed as below:
- extra_attr feature is enabled
- flexible_inline_xattr feature is enabled
- ri.i_inline_xattr_size = 2048
- F2FS_EXTRA_ATTR bit in ri.i_inline was not set
sanity_check_inode() will skip doing sanity check on fi->i_inline_xattr_size,
result in using invalid inline_xattr_size later incorrectly, fix it.
Meanwhile, let's fix to check lower boundary for .i_inline_xattr_size w/
MIN_INLINE_XATTR_SIZE like we did in parse_options().
There is a related issue reported by syzbot, Qasim Ijaz has anlyzed and
fixed it w/ very similar way [1], as discussed, we all agree that it will
be better to do sanity check in sanity_check_inode() for fix, so finally,
let's fix these two related bugs w/ current patch.
Including commit message from Qasim's patch as below, thanks a lot for
his contribution.
"In f2fs_getxattr(), the function lookup_all_xattrs() allocates a 12-byte
(base_size) buffer for an inline extended attribute. However, when
__find_inline_xattr() calls __find_xattr(), it uses the macro
"list_for_each_xattr(entry, addr)", which starts by calling
XATTR_FIRST_ENTRY(addr). This skips a 24-byte struct f2fs_xattr_header
at the beginning of the buffer, causing an immediate out-of-bounds read
in a 12-byte allocation. The subsequent !IS_XATTR_LAST_ENTRY(entry)
check then dereferences memory outside the allocated region, triggering
the slab-out-of bounds read.
This patch prevents the out-of-bounds read by adding a check to bail
out early if inline_size is too small and does not account for the
header plus the 4-byte value that IS_XATTR_LAST_ENTRY reads."

When the :mod: command is written into /sys/kernel/tracing/set_event (or
that file within an instance), if the module specified after the ":mod:"
is not yet loaded, it will store that string internally. When the module
is loaded, it will enable the events as if the module was loaded when the
string was written into the set_event file.
This can also be useful to enable events that are in the init section of
the module, as the events are enabled before the init section is executed.
This also works on the kernel command line:
trace_event=:mod:<module>
Will enable the events for <module> when it is loaded.

Add a :mod: command to enable only events from a given module from the
set_events file.
echo '*:mod:<module>' > set_events
Or
echo ':mod:<module>' > set_events
Will enable all events for that module. Specific events can also be
enabled via:
echo '<event>:mod:<module>' > set_events
Or
echo '<system>:<event>:mod:<module>' > set_events
Or
echo '*:<event>:mod:<module>' > set_events
The ":mod:" keyword is consistent with the function tracing filter to
enable functions from a given module.
