[ Upstream commit 96a30e469c ]
Instead of allocating and copying instruction history each time we
enqueue child verifier state, switch to a model where we use one common
dynamically sized array of instruction history entries across all states.
The key observation for proving this is correct is that instruction
history is only relevant while state is active, which means it either is
a current state (and thus we are actively modifying instruction history
and no other state can interfere with us) or we are checkpointed state
with some children still active (either enqueued or being current).
In the latter case our portion of instruction history is finalized and
won't change or grow, so as long as we keep it immutable until the state
is finalized, we are good.
Now, when state is finalized and is put into state hash for potentially
future pruning lookups, instruction history is not used anymore. This is
because instruction history is only used by precision marking logic, and
we never modify precision markings for finalized states.
So, instead of each state having its own small instruction history, we
keep a global dynamically-sized instruction history, where each state in
current DFS path from root to active state remembers its portion of
instruction history. Current state can append to this history, but
cannot modify any of its parent histories.
Async callback state enqueueing, while logically detached from parent
state, still is part of verification backtracking tree, so has to follow
the same schema as normal state checkpoints.
Because the insn_hist array can be grown through realloc, states don't
keep pointers, they instead maintain two indices, [start, end), into
global instruction history array. End is exclusive index, so
`start == end` means there is no relevant instruction history.
This eliminates a lot of allocations and minimizes overall memory usage.
For instance, running a worst-case test from [0] (but without the
heuristics-based fix [1]), it took 12.5 minutes until we get -ENOMEM.
With the changes in this patch the whole test succeeds in 10 minutes
(very slow, so heuristics from [1] is important, of course).
To further validate correctness, veristat-based comparison was performed for
Meta production BPF objects and BPF selftests objects. In both cases there
were no differences *at all* in terms of verdict or instruction and state
counts, providing a good confidence in the change.
Having this low-memory-overhead solution of keeping dynamic
per-instruction history cheaply opens up some new possibilities, like
keeping extra information for literally every single validated
instruction. This will be used for simplifying precision backpropagation
logic in follow up patches.

destination is greater than the source, the recovery operation
will fail and qemu will not be able to complete the process and
exit after shutting down the device FD.
This will cause the driver to be unable to be unloaded normally due
to abnormal reference counting of the live migration driver caused
by the abnormal closing operation of fd.
Therefore, make sure the migration file descriptor references are
always released when the device is closed.

The root cause is as below:
In the function rxe_create_qp, the function rxe_qp_from_init is called
to create qp, if this function rxe_qp_from_init fails, rxe_cleanup will
be called to handle all the allocated resources, including the timers:
retrans_timer and rnr_nak_timer.
The function rxe_qp_from_init calls the function rxe_qp_init_req to
initialize the timers: retrans_timer and rnr_nak_timer.
But these timers are initialized in the end of rxe_qp_init_req.
If some errors occur before the initialization of these timers, this
problem will occur.
The solution is to check whether these timers are initialized or not.
If these timers are not initialized, ignore these timers.

When the active link is changed for a bond device, the existing xfrm
states need to be migrated over to the new link. This is done with:
- bond_ipsec_del_sa_all() goes through the offloaded states list and
removes all of them from hw.
- bond_ipsec_add_sa_all() re-offloads all states to the new device.
But because the offload status of xfrm states isn't marked in any way,
there can be bugs.
When all bond links are down, bond_ipsec_del_sa_all() unoffloads
everything from the previous active link. If the same link then comes
back up, nothing gets reoffloaded by bond_ipsec_add_sa_all().
This results in a stack trace like this a bit later when user space

There's also another theoretical bug:
Calling bond_ipsec_del_sa_all() multiple times can result in corruption
in the driver implementation if the double-free isn't tolerated. This
isn't nice.
Before the "Fixes" commit, xs->xso.real_dev was set to NULL when an xfrm
state was unoffloaded from a device, but a race with netdevsim's
.xdo_dev_offload_ok() accessing real_dev was considered a sufficient
reason to not set real_dev to NULL anymore. This unfortunately
introduced the new bugs.
Since .xdo_dev_offload_ok() was significantly refactored by [1] and
there are no more users in the stack of xso.real_dev, that
race is now gone and xs->xso.real_dev can now once again be used to
represent which device (if any) currently holds the offloaded rule.
Go one step further and set real_dev after add/before delete calls, to
catch any future driver misuses of real_dev.

Commit 8d391972ae ("gfs2: Remove __gfs2_writepage()") changed the log
flush code in gfs2_ail1_start_one() to call aops->writepages() instead
of aops->writepage(). For jdata inodes, this means that we will now try
to reserve log space and start a transaction before we can determine
that the pages in question have already been journaled. When this
happens in the context of gfs2_logd(), it can now appear that not enough
log space is available for freeing up log space, and we will lock up.
Fix that by issuing journal writes directly instead of going through
aops->writepages() in the log flush code.

[ Upstream commit 17a85f5204 ]
If we're doing a mmap write against a folio that has i_size somewhere in
the middle and we have multiple sectors in the folio, we may have to
release excess space previously reserved, for the range going from the
rounded up (to sector size) i_size to the folio's end offset. We are
calculating the right amount to release and passing it to
btrfs_delalloc_release_space(), but we are passing the wrong start offset
of that range - we're passing the folio's start offset instead of the
end offset, plus 1, of the range for which we keep the reservation. This
may result in releasing more space then we should and eventually trigger
an underflow of the data space_info's bytes_may_use counter.
So fix this by passing the start offset as 'end + 1' instead of
'page_start' to btrfs_delalloc_release_space().

[ Upstream commit 2c63986dd3 ]
When creating and destroying inodes, we are relying on the inode hash
table to make sure that for a given inode number, only a single inode
will exist. We then link that inode to its inode and iopen glock and
let those glocks point back at the inode. However, when iget_failed()
is called, the inode is removed from the inode hash table before
gfs_evict_inode() is called, and uniqueness is no longer guaranteed.
Commit f1046a472b70 ("gfs2: gl_object races fix") was trying to work
around that problem by detaching the inode glock from the inode before
calling iget_failed(), but that broke the inode deallocation code in
gfs_evict_inode().
To fix that, deallocate partially created inodes in gfs2_create_inode()
instead of relying on gfs_evict_inode() for doing that.
This means that gfs2_evict_inode() and its helper functions will no
longer see partially created inodes, and so some simplifications are
possible there.
