The error handling calls kfree(full_path) so we can't let it be a NULL
pointer. There used to be a NULL assignment here but we accidentally
deleted it. Add it back.

Pull iomap updates from Darrick Wong:
"The most notable changes are:
- iomap no longer invalidates the page cache when performing a direct
read, since doing so is unnecessary and the old directio code
doesn't do that either.
- iomap embraced the use of returning ENOTBLK from a direct write to
trigger falling back to a buffered write since ext4 already did
this and btrfs wants it for their port.
- iomap falls back to buffered writes if we're doing a direct write
and the page cache invalidation after the flush fails; this was
necessary to handle a corner case in the btrfs port.
- Remove email virus scanner detritus that was accidentally included
in yesterday's pull request. Clearly I need(ed) to update my git
branch checker scripts. :("

Expose model and fw_version via sysfs. Also query the model
in probe to make sure, that the I2C communication with the
device works before successfully probing the driver.
This is a bit complicated, since EETI devices do not have
a sync interface. Sending the commands and directly reading
does not work. Sending the command and waiting for some time
is also not an option, since there might be touch events in
the mean time.
Last but not least we do not cache the results, since this
interface can be used to check the I2C communication is still
working as expected.

Currently when the call to fsp_reg_write fails -EIO is not being returned
because the count is being returned instead of the return value in retval.

Currently the assignment of -ENOMEM to error is redundant because error
is not being read and -ENOMEM is being hard coded as an error return.
Fix this by returning the error code in variable 'error'; this also
allows the error code from a failed call to input_register_device to
be preserved and returned to the caller rather than just returning
a possibly inappropriate -ENOMEM.
Kudos to Dan Carpenter for the suggestion of an improved fix.

1. Added a skb->len check
This driver expects upper layers to include a pseudo header of 1 byte
when passing down a skb for transmission. This driver will read this
1-byte header. This patch added a skb->len check before reading the
header to make sure the header exists.
2. Changed to use needed_headroom instead of hard_header_len to request
necessary headroom to be allocated
In net/packet/af_packet.c, the function packet_snd first reserves a
headroom of length (dev->hard_header_len + dev->needed_headroom).
Then if the socket is a SOCK_DGRAM socket, it calls dev_hard_header,
which calls dev->header_ops->create, to create the link layer header.
If the socket is a SOCK_RAW socket, it "un-reserves" a headroom of
length (dev->hard_header_len), and assumes the user to provide the
appropriate link layer header.
So according to the logic of af_packet.c, dev->hard_header_len should
be the length of the header that would be created by
dev->header_ops->create.
However, this driver doesn't provide dev->header_ops, so logically
dev->hard_header_len should be 0.
So we should use dev->needed_headroom instead of dev->hard_header_len
to request necessary headroom to be allocated.
This change fixes kernel panic when this driver is used with AF_PACKET
SOCK_RAW sockets.

Yonghong Song says:
====================
Andrii raised a concern that current uapi for bpf iterator map
element is a little restrictive and not suitable for future potential
complex customization. This is a valid suggestion, considering people
may indeed add more complex custimization to the iterator, e.g.,
cgroup_id + user_id, etc. for task or task_file. Another example might
be map_id plus additional control so that the bpf iterator may bail
out a bucket earlier if a bucket has too many elements which may hold
lock too long and impact other parts of systems.
Patch #1 modified uapi with kernel changes. Patch #2
adjusted libbpf api accordingly.
Changelogs:
v3 -> v4:
. add a forward declaration of bpf_iter_link_info in
tools/lib/bpf/bpf.h in case that libbpf is built against
not-latest uapi bpf.h.
. target the patch set to "bpf" instead of "bpf-next"
v2 -> v3:
. undo "not reject iter_info.map.map_fd == 0" from v1.
In the future map_fd may become optional, so let us use map_fd == 0
indicating the map_fd is not set by user space.
. add link_info_len to bpf_iter_attach_opts to ensure always correct
link_info_len from user. Otherwise, libbpf may deduce incorrect
link_info_len if it uses different uapi header than the user app.
v1 -> v2:
. ensure link_create target_fd/flags == 0 since they are not used. (Andrii)
. if either of iter_info ptr == 0 or iter_info_len == 0, but not both,
return error to user space. (Andrii)
. do not reject iter_info.map.map_fd == 0, go ahead to use it trying to
get a map reference since the map_fd is required for map_elem iterator.
. use bpf_iter_link_info in bpf_iter_attach_opts instead of map_fd.
this way, user space is responsible to set up bpf_iter_link_info and
libbpf just passes the data to the kernel, simplifying libbpf design.

Previous commit adjusted kernel uapi for map
element bpf iterator. This patch adjusted libbpf API
due to uapi change. bpftool and bpf_iter selftests
are also changed accordingly.

Commit a5cbe05a6673 ("bpf: Implement bpf iterator for
map elements") added bpf iterator support for
map elements. The map element bpf iterator requires
info to identify a particular map. In the above
commit, the attr->link_create.target_fd is used
to carry map_fd and an enum bpf_iter_link_info
is added to uapi to specify the target_fd actually
representing a map_fd:
enum bpf_iter_link_info {
BPF_ITER_LINK_UNSPEC = 0,
BPF_ITER_LINK_MAP_FD = 1,
MAX_BPF_ITER_LINK_INFO,
};
This is an extensible approach as we can grow
enumerator for pid, cgroup_id, etc. and we can
unionize target_fd for pid, cgroup_id, etc.
But in the future, there are chances that
more complex customization may happen, e.g.,
for tasks, it could be filtered based on
both cgroup_id and user_id.
This patch changed the uapi to have fields
__aligned_u64 iter_info;
__u32 iter_info_len;
for additional iter_info for link_create.
The iter_info is defined as
union bpf_iter_link_info {
struct {
__u32 map_fd;
} map;
};
So future extension for additional customization
will be easier. The bpf_iter_link_info will be
passed to target callback to validate and generic
bpf_iter framework does not need to deal it any
more.
Note that map_fd = 0 will be considered invalid
and -EBADF will be returned to user space.

runqslower's Makefile is building/installing bpftool into
$(OUTPUT)/sbin/bpftool, which coincides with $(DEFAULT_BPFTOOL). In practice
this means that often when building selftests from scratch (after `make
clean`), selftests are racing with runqslower to simultaneously build bpftool
and one of the two processes fail due to file being busy. Prevent this race by
explicitly order-depending on $(BPFTOOL_DEFAULT).

An xstate size check warning is triggered on machines which support
Architectural LBRs.
XSAVE consistency problem, dumping leaves
WARNING: CPU: 0 PID: 0 at arch/x86/kernel/fpu/xstate.c:649 fpu__init_system_xstate+0x4d4/0xd0e
Modules linked in:
CPU: 0 PID: 0 Comm: swapper Not tainted intel-arch_lbr+
RIP: 0010:fpu__init_system_xstate+0x4d4/0xd0e
The xstate size check routine, init_xstate_size(), compares the size
retrieved from the hardware with the size of task->fpu, which is
calculated by the software.
The size from the hardware is the total size of the enabled xstates in
XCR0 | IA32_XSS. Architectural LBR state is a dynamic supervisor
feature, which sets the corresponding bit in the IA32_XSS at boot time.
The size from the hardware includes the size of the Architectural LBR
state.
However, a dynamic supervisor feature doesn't allocate a buffer in the
task->fpu. The size of task->fpu doesn't include the size of the
Architectural LBR state. The mismatch will trigger the warning.
Three options as below were considered to fix the issue:
- Correct the size from the hardware by subtracting the size of the
dynamic supervisor features.
The purpose of the check is to compare the size CPU told with the size
of the XSAVE buffer, which is calculated by the software. If the
software mucks with the number from hardware, it removes the value of
the check.
This option is not a good option.
- Prevent the hardware from counting the size of the dynamic supervisor
feature by temporarily removing the corresponding bits in IA32_XSS.
Two extra MSR writes are required to flip the IA32_XSS. The option is
not pretty, but it is workable. The check is only called once at early
boot time. The synchronization or context-switching doesn't need to be
worried.
This option is implemented here.
- Remove the check entirely, because the check hasn't found any real
problems. The option may be an alternative as option 2.
This option is not implemented here.
Add a new function, get_xsaves_size_no_dynamic(), which retrieves the
total size without the dynamic supervisor features from the hardware.
The size will be used to compare with the size of task->fpu.

Purgatory.ro is a standalone binary that is not linked against the rest of
the kernel. Its image is copied into an array that is linked to the
kernel, and from there kexec relocates it wherever it desires.
Unlike the debug info for vmlinux, which can be used for analyzing crash
such info is useless in purgatory.ro. And discarding them can save about
200K space.

The crash_exclude_mem_range() function can only handle one memory region a time.
It will fail in the case in which the passed in area covers several memory
regions. In this case, it will only exclude the first region, then return,
but leave the later regions unsolved.
E.g in a NEC system with two usable RAM regions inside the low 1M:
...
BIOS-e820: [mem 0x0000000000000000-0x000000000003efff] usable
BIOS-e820: [mem 0x000000000003f000-0x000000000003ffff] reserved
BIOS-e820: [mem 0x0000000000040000-0x000000000009ffff] usable
It will only exclude the memory region [0, 0x3efff], the memory region
[0x40000, 0x9ffff] will still be added into /proc/vmcore, which may cause
the following failure when dumping vmcore:
ioremap on RAM at 0x0000000000040000 - 0x0000000000040fff
WARNING: CPU: 0 PID: 665 at arch/x86/mm/ioremap.c:186 __ioremap_caller+0x2c7/0x2e0
