It is not safe to dereference fl->c.flc_owner without first confirming
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()
tests fl_lmops but largely ignores the result and assumes that flc_owner
is an nfs4_delegation anyway. This is wrong.
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave
as it did before the change mentioned below. This is the same as the
current code, but without any reference to a possible delegation.

Currently, we copy the mtime and ctime to the in-core inode and then
mark the inode dirty. This is fine for certain types of filesystems, but
not all. Some require a real setattr to properly change these values
(e.g. ceph or reexported NFS).
Fix this code to call notify_change() instead, which is the proper way
to effect a setattr. There is one problem though:
In this case, the client is holding a write delegation and has sent us
attributes to update our cache. We don't want to break the delegation
for this since that would defeat the purpose. Add a new ATTR_DELEG flag
that makes notify_change bypass the try_break_deleg call.

Prior to commit 3f29cc82a8 ("nfsd: split sc_status out of
sc_type") states_show() relied on sc_type field to be of valid
type before calling into a subfunction to show content of a
particular stateid. From that commit, we split the validity of
the stateid into sc_status and no longer changed sc_type to 0
while unhashing the stateid. This resulted in kernel oopsing
for nfsv4.0 opens that stay around and in nfs4_show_open()
would derefence sc_file which was NULL.
Instead, for closed open stateids forgo displaying information
that relies of having a valid sc_file.
To reproduce: mount the server with 4.0, read and close
a file and then on the server cat /proc/fs/nfsd/clients/2/states

Only pooled services take a reference to the svc_pool_map. The sunrpc
code has always used the sv_nrpools value to detect whether the service
is pooled.
The problem there is that nfsd is a pooled service, but when it's
running in "global" pool_mode, it doesn't take a reference to the pool
map because it has a sv_nrpools value of 1. This means that we have
two separate codepaths for starting the server, depending on whether
it's pooled or not.
Fix this by adding a new flag to the svc_serv, that indicates whether
the serv is pooled. With this we can have the nfsd service
unconditionally take a reference, regardless of pool_mode.
Note that this is a behavior change for
/sys/module/sunrpc/parameters/pool_mode. Usually this file does not
allow you to change the pool-mode while there are nfsd threads running,
but if the pool-mode is "global" it's allowed. My assumption is that
this is a bug, since it probably should never have worked this way.
This patch changes the behavior such that you get back EBUSY even
when nfsd is running in global mode. I think this is more reasonable
behavior, and given that most people set this today using the module
parameter, it's doubtful anyone will notice.

I noticed LAYOUTGET(LAYOUTIOMODE4_RW) returning NFS4ERR_ACCESS
unexpectedly. The NFS client had created a file with mode 0444, and
the server had returned a write delegation on the OPEN(CREATE). The
client was requesting a RW layout using the write delegation stateid
so that it could flush file modifications.
Creating a read-only file does not seem to be problematic for
NFSv4.1 without pNFS, so I began looking at NFSD's implementation of
LAYOUTGET.
The failure was because fh_verify() was doing a permission check as
part of verifying the FH presented during the LAYOUTGET. It uses the
loga_iomode value to specify the @accmode argument to fh_verify().
fh_verify(MAY_WRITE) on a file whose mode is 0444 fails with -EACCES.
To permit LAYOUT* operations in this case, add OWNER_OVERRIDE when
checking the access permission of the incoming file handle for
LAYOUTGET and LAYOUTCOMMIT.

These lengths come from xdr_stream_decode_u32() and so we should be a
bit careful with them. Use size_add() and struct_size() to avoid
integer overflows. Saving size_add()/struct_size() results to a u32 is
unsafe because it truncates away the high bits.
Also generally storing sizes in longs is safer. Most systems these days
use 64 bit CPUs. It's harder for an addition to overflow 64 bits than
it is to overflow 32 bits. Also functions like vmalloc() can
successfully allocate UINT_MAX bytes, but nothing can allocate ULONG_MAX
bytes.

powerpc/64s: Fix unnecessary copy to 0 when kernel is booted at address 0
Currently building the powerpc selftests with USERCFLAGS set to anything
causes the build to break:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error

gcc -Wno-error cache_shape.c ...
cache_shape.c:18:10: fatal error: utils.h: No such file or directory
18 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which
causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at
all, resulting in none of the usual CFLAGS being passed. That can
be seen in the output above, the only flag passed to the compiler is
-Wno-error.
Fix it by dropping the conditional setting of CFLAGS in flags.mk.
Instead always set CFLAGS, but also append USERCFLAGS if they are set.
Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk
is included by multiple Makefiles (to support partial builds), causing
CFLAGS to be appended to multiple times. Additionally that would place
the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS
couldn't override the standard flags. Being able to override the
standard flags is desirable, for example for adding -Wno-error.
With the fix in place, the CFLAGS are set correctly, including the
USERCFLAGS:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error

Merge tag 'riscv-for-linus-6.10-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
- A fix for the CMODX example in the recently added icache flushing
prctl()
- A fix to the perf driver to avoid corrupting event data on counter
overflows when external overflow handlers are in use
- A fix to clear all hardware performance monitor events on boot, to
avoid dangling events firmware or previously booted kernels from
triggering spuriously
- A fix to the perf event probing logic to avoid erroneously reporting
the presence of unimplemented counters. This also prevents some
implemented counters from being reported
- A build fix for the vector sigreturn selftest on clang
- A fix to ftrace, which now requires the previously optional index
argument to ftrace_graph_ret_addr()
- A fix to avoid deadlocking if kexec crash handling triggers in an
interrupt context

Merge tag 'i2c-host-fixes-6.10-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
This tag includes a nice fix in the PNX driver that has been
pending for a long time. Piotr has replaced a potential lock in
the interrupt context with a more efficient and straightforward
handling of the timeout signaling.
DTS for Nokia N900 incorrectly specifies "active high" polarity for
the reset line, while the chip documentation actually specifies it as
"active low". In the past the driver fudged gpiod API and inverted
the logic internally, but it was changed in d0d89493bf.
