[ Upstream commit 6a4730b325aaa48f7a5d5ba97aff0a955e2d9cec ]
This BUG_ON is meant to catch backref cache problems, but these can
arise from either bugs in the backref cache or corruption in the extent
tree. Fix it to be a proper error.

commit d0f038104fa37380e2a725e669508e43d0c503e9 upstream.
There is a recent ML report that mounting a large fs backed by hardware
RAID56 controller (with one device missing) took too much time, and
systemd seems to kill the mount attempt.
In that case, the only error message is:
BTRFS error (device sdj): open_ctree failed
There is no reason on why the failure happened, making it very hard to
understand the reason.
At least output the error number (in the particular case it should be
-EINTR) to provide some clue.

commit c6ef3a7fa97ec823a1e1af9085cf13db9f7b3bac upstream.
If the uvc_status_init() function fails to allocate the int_urb, it will
free the dev->status pointer but doesn't reset the pointer to NULL. This
results in the kfree() call in uvc_status_cleanup() trying to
double-free the memory. Fix it by resetting the dev->status pointer to
NULL after freeing it.

commit 64f2657b579343cf923aa933f08074e6258eb07b upstream.
A report in 2019 by the syzbot fuzzer was found to be connected to two
errors in the HID core associated with Resolution Multipliers. One of
the errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloop
in hid_apply_multiplier."), but the other has not been fixed.
This error arises because hid_apply_multipler() assumes that every
Resolution Multiplier control is contained in a Logical Collection,
i.e., there's no way the routine can ever set multiplier_collection to
NULL. This is in spite of the fact that the function starts with a
big comment saying:
* "The Resolution Multiplier control must be contained in the same
* Logical Collection as the control(s) to which it is to be applied.
...
* If no Logical Collection is
* defined, the Resolution Multiplier is associated with all
* controls in the report."
* HID Usage Table, v1.12, Section 4.3.1, p30
*
* Thus, search from the current collection upwards until we find a
* logical collection...
The comment and the code overlook the possibility that none of the
collections found may be a Logical Collection.
The fix is to set the multiplier_collection pointer to NULL if the
collection found isn't a Logical Collection.

commit 961b4b5e86bf56a2e4b567f81682defa5cba957e upstream.
I noticed that once an NFSv4.1 callback operation gets a
NFS4ERR_DELAY status on CB_SEQUENCE and then the connection is lost,
the callback client loops, resending it indefinitely.
The switch arm in nfsd4_cb_sequence_done() that handles
NFS4ERR_DELAY uses rpc_restart_call() to rearm the RPC state machine
for the retransmit, but that path does not call the rpc_prepare_call
callback again. Thus cb_seq_status is set to -10008 by the first
NFS4ERR_DELAY result, but is never set back to 1 for the retransmits.
nfsd4_cb_sequence_done() thinks it's getting nothing but a
long series of CB_SEQUENCE NFS4ERR_DELAY replies.

When a symbol that is already registered is read again from *.symref
file, __add_symbol() removes the previous one from the hash table without
freeing it.
[Test Case]
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) {}
EXPORT_SYMBOL(foo);
$ cat foo.symref
foo void foo ( void )
foo void foo ( void )
When a symbol is removed from the hash table, it must be freed along
with its ->name and ->defn members. However, sym->name cannot be freed
because it is sometimes shared with node->string, but not always. If
sym->name and node->string share the same memory, free(sym->name) could
lead to a double-free bug.
To resolve this issue, always assign a strdup'ed string to sym->name.

[ Upstream commit 45c9c4101d3d2fdfa00852274bbebba65fcc3cf2 ]
When a symbol that is already registered is added again, __add_symbol()
returns without freeing the symbol definition, making it unreachable.
The following test cases demonstrate different memory leak points.
[Test Case 1]
Forward declaration with exactly the same definition
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) {}
EXPORT_SYMBOL(foo);
[Test Case 2]
Forward declaration with a different definition (e.g. attribute)
$ cat foo.c
#include <linux/export.h>
void foo(void);
__attribute__((__section__(".ref.text"))) void foo(void) {}
EXPORT_SYMBOL(foo);
[Test Case 3]
Preserving an overridden symbol (compile with KBUILD_PRESERVE=1)
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) { }
EXPORT_SYMBOL(foo);
$ cat foo.symref
override foo void foo ( int )
The memory leaks in Test Case 1 and 2 have existed since the introduction
of genksyms into the kernel tree. [1]
The memory leak in Test Case 3 was introduced by commit 5dae9a550a
("genksyms: allow to ignore symbol checksum changes").
When multiple init_declarators are reduced to an init_declarator_list,
the decl_spec must be duplicated. Otherwise, the following Test Case 4
would result in a double-free bug.
[Test Case 4]
$ cat foo.c
#include <linux/export.h>
extern int foo, bar;
int foo, bar;
EXPORT_SYMBOL(foo);
In this case, 'foo' and 'bar' share the same decl_spec, 'int'. It must
be unshared before being passed to add_symbol().

imx_media_add_of_subdevs() calls of_parse_phandle() and passes the
obtained node to imx_media_of_add_csi(). The passed node is used in
v4l2_async_nf_add_fwnode(), which increments the refcount of the node.
Therefore, while the current implementation only releases the node when
imx_media_of_add_csi() fails, but should always release it. Call

The devm_pci_epc_destroy() comment says destroys the EPC device, but it
does not actually do that since devres_destroy() does not call
devm_pci_epc_release(), and it also can not fully undo what the API
devm_pci_epc_create() does, so it is faulty.
Fortunately, the faulty API has not been used by current kernel tree. Use
devres_release() instead of devres_destroy() so the EPC device will be
released.

to a bug that was not setting the end address on kernel functions
implemented in assembly (see Link: tag), and then those were not being
found by machine__resolve() -> map__find_symbol().
So we ended up with:
# perf top --stdio
PerfTop: 0 irqs/s kernel: 0% exact: 0% lost: 0/0 drop: 0/0 [cycles/P]
-----------------------------------------------------------------------
Warning:
A vmlinux file was not found.
Kernel samples will not be resolved.

#
But then resolving all other kernel symbols.
So just fixup the logic to only print that warning when there are no
symbols in the kernel map.
