Pull selinux updates from Paul Moore:
"We've got a few SELinux patches for the v5.2 merge window, the
highlights are below:
- Add LSM hooks, and the SELinux implementation, for proper labeling
of kernfs. While we are only including the SELinux implementation
here, the rest of the LSM folks have given the hooks a thumbs-up.
- Update the SELinux mdp (Make Dummy Policy) script to actually work
on a modern system.
- Disallow userspace to change the LSM credentials via
/proc/self/attr when the task's credentials are already overridden.
The change was made in procfs because all the LSM folks agreed this
was the Right Thing To Do and duplicating it across each LSM was
going to be annoying"

Convert livepatch documentation to ReST format. The changes
are mostly trivial, as the documents are already on a good
shape. Just a few markup changes are needed for Sphinx to
properly parse the docs.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- The in-file TOC becomes a comment, in order to skip it from the
output, as Sphinx already generates an index there.
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Use bios to read in the journal into the address space of the journal inode
(jd_inode), sequentially and in large chunks. This is faster for locating the
journal head that the previous binary search approach. When performing
recovery, we keep the journal in the address space until recovery is done,
which further speeds up things.

Since commit 64bc06bb32ee ("gfs2: iomap buffered write support"), gfs2 is doing
buffered writes by starting a transaction in iomap_begin, writing a range of
pages, and ending that transaction in iomap_end. This approach suffers from
two problems:
(1) Any allocations necessary for the write are done in iomap_begin, so when
the data aren't journaled, there is no need for keeping the transaction open
until iomap_end.
(2) Transactions keep the gfs2 log flush lock held. When
iomap_file_buffered_write calls balance_dirty_pages, this can end up calling
gfs2_write_inode, which will try to flush the log. This requires taking the
log flush lock which is already held, resulting in a deadlock.
Fix both of these issues by not keeping transactions open from iomap_begin to
iomap_end. Instead, start a small transaction in page_prepare and end it in
page_done when necessary.

As part of the freeze operation, gfs2_freeze_func() is left blocking
on a request to hold the sd_freeze_gl in SH. This glock is held in EX
by the gfs2_freeze() code.
A subsequent call to gfs2_unfreeze() releases the EXclusively held
sd_freeze_gl, which allows gfs2_freeze_func() to acquire it in SH and
resume its operation.
gfs2_unfreeze(), however, doesn't wait for gfs2_freeze_func() to complete.
If a umount is issued right after unfreeze, it could result in an
inconsistent filesystem because some journal data (statfs update) isn't
written out.
Refer to commit 24972557b12c for a more detailed explanation of how
freeze/unfreeze work.
This patch causes gfs2_unfreeze() to wait for gfs2_freeze_func() to
complete before returning to the user.

The gl_revokes value determines how many outstanding revokes a glock has
on the superblock revokes list; this is used to avoid unnecessary log
flushes. However, gl_revokes is only ever tested for being zero, and it's
only decremented in revoke_lo_after_commit, which removes all revokes
from the list, so we know that the gl_revoke values of all the glocks on
the list will reach zero. Therefore, we can replace gl_revokes with a
bit flag. This saves an atomic counter in struct gfs2_glock.

This patch has to do with the life cycle of glocks and buffers. When
gfs2 metadata or journaled data is queued to be written, a gfs2_bufdata
object is assigned to track the buffer, and that is queued to various
lists, including the glock's gl_ail_list to indicate it's on the active
items list. Once the page associated with the buffer has been written,
it is removed from the ail list, but its life isn't over until a revoke
has been successfully written.
So after the block is written, its bufdata object is moved from the
glock's gl_ail_list to a file-system-wide list of pending revokes,
sd_log_le_revoke. At that point the glock still needs to track how many
revokes it contributed to that list (in gl_revokes) so that things like
glock go_sync can ensure all the metadata has been not only written, but
also revoked before the glock is granted to a different node. This is
to guarantee journal replay doesn't replay the block once the glock has
been granted to another node.
Ross Lagerwall recently discovered a race in which an inode could be
evicted, and its glock freed after its ail list had been synced, but
while it still had unwritten revokes on the sd_log_le_revoke list. The
evict decremented the glock reference count to zero, which allowed the
glock to be freed. After the revoke was written, function
revoke_lo_after_commit tried to adjust the glock's gl_revokes counter
and clear its GLF_LFLUSH flag, at which time it referenced the freed
glock.
This patch fixes the problem by incrementing the glock reference count
in gfs2_add_revoke when the glock's first bufdata object is moved from
the glock to the global revokes list. Later, when the glock's last such
bufdata object is freed, the reference count is decremented. This
guarantees that whichever process finishes last (the revoke writing or
the evict) will properly free the glock, and neither will reference the
glock after it has been freed.

This patch fixes regressions in 588bff95c94efc05f9e1a0b19015c9408ed7c0ef.
Due to that patch, function clean_journal was setting the value of
sd_log_flush_head, but that's only valid if it is replaying the node's
own journal. If it's replaying another node's journal, that's completely
wrong and will lead to multiple problems. This patch tries to clean up
the mess by passing the value of the logical journal block number into
gfs2_write_log_header so the function can treat non-owned journals
generically. For the local journal, the journal extent map is used for
best performance. For other nodes from other journals, new function
gfs2_lblk_to_dblk is called to figure it out using gfs2_iomap_get.
This patch also tries to establish more consistency when passing journal
block parameters by changing several unsigned int types to a consistent
u32.

Use udf as the guard instruction for the restartable sequence abort
handler.
Previously, the chosen signature was not a valid instruction, based
on the assumption that it could always sit in a literal pool. However,
there are compilation environments in which literal pools are not
available, for instance execute-only code. Therefore, we need to
choose a signature value that is also a valid instruction.
Handle compiling with -mbig-endian on ARMv6+, which generates binaries

Else mismatch between code endianness for the generated signatures and
data endianness for the RSEQ_SIG parameter passed to the rseq
registration will trigger application segmentation faults when the
kernel try to abort rseq critical sections.
Prior to ARMv6, -mbig-endian generates big-endian code and data, so
endianness should not be reversed in that case.

In order to integrate rseq into user-space applications, expose a
__rseq_handled symbol so many rseq users can be linked into the same
application (e.g. librseq and glibc).
The __rseq_refcount TLS variable is static to the librseq library. It
ensures that rseq syscall registration/unregistration happens only for
the most early/late caller to rseq_{,un}register_current_thread for each
thread, thus ensuring that rseq is registered across the lifetime of all
rseq users for a given thread.

The entries within __rseq_table are aligned on 32 bytes due to
linux/rseq.h struct rseq_cs uapi requirements, but the start of the
__rseq_table section is not guaranteed to be 32-byte aligned. It can
cause padding to be added at the start of the section, which makes it
hard to use as an array of items by debuggers.
Considering that __rseq_table does not really consist of a table due to
the presence of padding, rename this section to __rseq_cs.
Create a new __rseq_cs_ptr_array section which contains 64-bit packed
pointers to entries within the __rseq_cs section.

gcc-8 version 8.1.0, 8.2.0, and 8.3.0 generate broken assembler with asm
goto that have a thread-local storage "m" input operand on both x86-32
and x86-64. For instance:
__thread int var;
static int fct(void)
{
asm goto ( "jmp %l[testlabel]\n\t"
: : [var] "m" (var) : : testlabel);
return 0;
testlabel:
return 1;
}
int main()
{
return fct();
}
% gcc-8 -O2 -o test-asm-goto test-asm-goto.c
/tmp/ccAdHJbe.o: In function `main':
test-asm-goto.c:(.text.startup+0x1): undefined reference to `.L2'

/tmp/ccREsVXA.o: In function `main':

Work-around this compiler bug in the rseq-x86.h header by passing the
address of the __rseq_abi TLS as a register operand rather than using
the "m" input operand.

Setting a chip for an interrupt marks it as allocated. Since UM doesn't
support dynamic interrupt numbers (yet), it means we cannot simply
increase NR_IRQS and then use the free irqs between LAST_IRQ and NR_IRQS
with gpio-mockup or iio testing drivers as irq_alloc_descs() will fail
after not being able to neither find an unallocated range of interrupts
nor expand the range.
Only call irq_set_chip_and_handler() for irqs until LAST_IRQ.

Reverts commit b6024b21fec8367ef961a771cc9dde31f1831965 and
adjusts default stack sizing to cope with larger size of
floating point save registers on the newer Intel CPUs.
b6024b21fec8367ef961a771cc9dde31f1831965 replaced storing the
register state on the stack with kmalloc-ed storage. That has
a number of issues and a panic if that fails.
1. kmalloc/ATOMIC can fail. There was a latent hard crash
in all interrupt and fault handling as a result.
2. kmalloc in the interrupt path introduces a considerable
performance penalty for networking ~ 14% on iperf.
This commit restores uml to a stable state until a better
solution is found.

Under certain conditions, lru_count may drop below zero resulting in
a large amount of log spam like this:
vmscan: shrink_slab: gfs2_dump_glock+0x3b0/0x630 [gfs2] \
negative objects to delete nr=-1
This happens as follows:
1) A glock is moved from lru_list to the dispose list and lru_count is
decremented.
2) The dispose function calls cond_resched() and drops the lru lock.
3) Another thread takes the lru lock and tries to add the same glock to
lru_list, checking if the glock is on an lru list.
4) It is on a list (actually the dispose list) and so it avoids
incrementing lru_count.
5) The glock is moved to lru_list.
5) The original thread doesn't dispose it because it has been re-added
to the lru list but the lru_count has still decreased by one.
Fix by checking if the LRU flag is set on the glock rather than checking
if the glock is on some list and rearrange the code so that the LRU flag
is added/removed precisely when the glock is added/removed from lru_list.

Fix the resource group wrap-around logic in gfs2_rbm_find that commit
e579ed4f44 broke. The bug can lead to unnecessary repeated scanning of the
same bitmaps; there is a risk that future changes will turn this into an
endless loop.
This is an updated version of commit 2d29f6b96d ("gfs2: Fix loop in
gfs2_rbm_find") which ended up being reverted because it introduced a
performance regression in iozone (see commit e74c98ca2d). Changes since v1:
- Simplify the wrap-around logic.
- Handle the case where each resource group only has a single bitmap block
(small filesystem).
- Update rd_extfail_pt whenever we scan the entire bitmap, even when we don't
start the scan at the very beginning of the bitmap.
