Currently it doesn't handle tasks in chroot properly. As filenames in
MMAP records base on their root directory, it's different than what perf
tool can see from outside.
Add filename_with_chroot() helper to deal with those cases. The

directory. Since it needs to access /proc for the process, it only
works until the task exits.

audit: don't deref the syscall args when checking the openat2 open_how::flags
The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.
This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.
tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16. To
avert any risk of bit overflow, we add an extra sanity check for this in
that function. We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer. This potential problem was identified by Eric Dumazet.

Commit 3ba442d533 ("fs: move binfmt_misc sysctl to its own file") did
not go unnoticed, binfmt-support stopped to work on my Debian system
since v5.17-rc2 (did not check with -rc1).
The existance of the /proc/sys/fs/binfmt_misc is a precondition for
attempting to mount the binfmt_misc fs, which in turn triggers the
autoload of the binfmt_misc module. Without it, no module is loaded and
no binfmt is available at boot.
Building as built-in or manually loading the module and mounting the fs
works fine, it's therefore only a matter of interaction with user-space.
I could try to improve the Debian systemd configuration but I can't say
anything about the other distributions.
This patch restores a working system right after boot.

Since, well, forever, the Linux NFS server's nfsd_commit() function
has returned nfserr_inval when the passed-in byte range arguments
were non-sensical.
However, according to RFC 1813 section 3.3.21, NFSv3 COMMIT requests
are permitted to return only the following non-zero status codes:
NFS3ERR_IO
NFS3ERR_STALE
NFS3ERR_BADHANDLE
NFS3ERR_SERVERFAULT
NFS3ERR_INVAL is not included in that list. Likewise, NFS4ERR_INVAL
is not listed in the COMMIT row of Table 6 in RFC 8881.
RFC 7530 does permit COMMIT to return NFS4ERR_INVAL, but does not
specify when it can or should be used.
Instead of dropping or failing a COMMIT request in a byte range that
is not supported, turn it into a valid request by treating one or
both arguments as zero. Offset zero means start-of-file, count zero
means until-end-of-file, so we only ever extend the commit range.
NFS servers are always allowed to commit more and sooner than
requested.
The range check is no longer bounded by NFS_OFFSET_MAX, but rather
by the value that is returned in the maxfilesize field of the NFSv3
FSINFO procedure or the NFSv4 maxfilesize file attribute.
Note that this change results in a new pynfs failure:
CMT4 st_commit.testCommitOverflow : RUNNING
CMT4 st_commit.testCommitOverflow : FAILURE
COMMIT with offset + count overflow should return
NFS4ERR_INVAL, instead got NFS4_OK
IMO the test is not correct as written: RFC 8881 does not allow the
COMMIT operation to return NFS4ERR_INVAL.

iattr::ia_size is a loff_t, so these NFSv3 procedures must be
careful to deal with incoming client size values that are larger
than s64_max without corrupting the value.
Silently capping the value results in storing a different value
than the client passed in which is unexpected behavior, so remove
the min_t() check in decode_sattr3().
Note that RFC 1813 permits only the WRITE procedure to return
NFS3ERR_FBIG. We believe that NFSv3 reference implementations
also return NFS3ERR_FBIG when ia_size is too large.

iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and
NFSv4 both define file size as an unsigned 64-bit type. Thus there
is a range of valid file size values an NFS client can send that is
already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If
that value happens to be larger than S64_MAX, then ia_size
underflows. I'm about to fix up the NFSv3 behavior as well, so let's
catch the underflow in the common code path: nfsd_setattr().

The Linux NFS client does not handle NFS?ERR_INVAL, even though all
NFS specifications permit servers to return that status code for a
READ.
Instead of NFS?ERR_INVAL, have out-of-range READ requests succeed
and return a short result. Set the EOF flag in the result to prevent
the client from retrying the READ request. This behavior appears to
be consistent with Solaris NFS servers.
Note that NFSv3 and NFSv4 use u64 offset values on the wire. These
must be converted to loff_t internally before use -- an implicit
type cast is not adequate for this purpose. Otherwise VFS checks
against sb->s_maxbytes do not work properly.

Originally we proposed a new hdmi-5v-supply regulator reference
for CI20 device tree but that was superseded by a better idea to use
the already defined "ddc-en-gpios" property of the "hdmi-connector".
Since "MIPS: DTS: CI20: Add DT nodes for HDMI setup" has already
been applied to v5.17-rc1, we add this on top.

->sock can be set to NULL asynchronously unless ->recv_mutex is held.
So it is important to hold that mutex. Otherwise a sysfs read can
trigger an oops.
Commit 17f09d3f61 ("SUNRPC: Check if the xprt is connected before
handling sysfs reads") appears to attempt to fix this problem, but it
only narrows the race window.

For some long forgotten reason, the nfs_client cl_flags field is
initialised in nfs_get_client() instead of being initialised at

nfs_create_rpc_client().

The concurrent positioning ranges log page 47h is a general purpose log
page and not a subpage of the indentify device log. Using
ata_identify_page_supported() to test for concurrent positioning ranges
support is thus wrong. ata_log_supported() must be used.
Furthermore, unlike other advanced ATA features (e.g. NCQ priority),
accesses to the concurrent positioning ranges log page are not gated by
a feature bit from the device IDENTIFY data. Since many older drives
react badly to the READ LOG EXT and/or READ LOG DMA EXT commands isued
to read device log pages, avoid problems with older drives by limiting
the concurrent positioning ranges support detection to drives
implementing at least the ACS-4 ATA standard (major version 11). This
additional condition effectively turns ata_dev_config_cpr() into a nop
for older drives, avoiding problems in the field.
