The CAP_NET_ADMIN checks are needed to prevent attackers faking a
device under NCIUARTSETDRIVER and exploit privileged commands.
This patch add GENL_ADMIN_PERM flags in genl_ops to fulfill the check.
Except for commands like NFC_CMD_GET_DEVICE, NFC_CMD_GET_TARGET,
NFC_CMD_LLC_GET_PARAMS, and NFC_CMD_GET_SE, which are mainly information-
read operations.

====================
security: fixups for the security hooks in sctp
There are a couple of problems in the currect security hooks in sctp:
1. The hooks incorrectly treat sctp_endpoint in SCTP as request_sock in
TCP, while it's in fact no more than an extension of the sock, and
represents the local host. It is created when sock is created, not
when a conn request comes. sctp_association is actually the correct
one to represent the connection, and created when a conn request
arrives.
2. security_sctp_assoc_request() hook should also be called in processing
COOKIE ECHO, as that's the place where the real assoc is created and
used in the future.
The problems above may cause accept sk, peeloff sk or client sk having
the incorrect security labels.
So this patchset is to change some hooks and pass asoc into them and save
these secids into asoc, as well as add the missing sctp_assoc_request
hook into the COOKIE ECHO processing.
v1->v2:
- See each patch, and thanks the help from Ondrej, Paul and Richard.

Different from selinux_inet_conn_established(), it also gives the
secid to asoc->peer_secid in selinux_sctp_assoc_established(),
as one UDP-type socket may have more than one asocs.
Note that peer_secid in asoc will save the peer secid for this
asoc connection, and peer_sid in sksec will just keep the peer
secid for the latest connection. So the right use should be do
peeloff for UDP-type socket if there will be multiple asocs in
one socket, so that the peeloff socket has the right label for
its asoc.
v1->v2:
- call selinux_inet_conn_established() to reduce some code
duplication in selinux_sctp_assoc_established(), as Ondrej
suggested.
- when doing peeloff, it calls sock_create() where it actually
gets secid for socket from socket_sockcreate_sid(). So reuse
SECSID_WILD to ensure the peeloff socket keeps using that
secid after calling selinux_sctp_sk_clone() for client side.

security_sctp_assoc_established() is added to replace
security_inet_conn_established() called in
sctp_sf_do_5_1E_ca(), so that asoc can be accessed in security
subsystem and save the peer secid to asoc->peer_secid.
v1->v2:
- fix the return value of security_sctp_assoc_established() in
security.h, found by kernel test robot and Ondrej.

The asoc created when receives the INIT chunk is a temporary one, it
will be deleted after INIT_ACK chunk is replied. So for the real asoc
created in sctp_sf_do_5_1D_ce() when the COOKIE_ECHO chunk is received,
security_sctp_assoc_request() should also be called.
v1->v2:
- fix some typo and grammar errors, noticed by Ondrej.

This patch is to move secid and peer_secid from endpoint to association,
and pass asoc to sctp_assoc_request and sctp_sk_clone instead of ep. As
ep is the local endpoint and asoc represents a connection, and in SCTP
one sk/ep could have multiple asoc/connection, saving secid/peer_secid
for new asoc will overwrite the old asoc's.
Note that since asoc can be passed as NULL, security_sctp_assoc_request()
is moved to the place right after the new_asoc is created in
sctp_sf_do_5_1B_init() and sctp_sf_do_unexpected_init().
v1->v2:
- fix the description of selinux_netlbl_skbuff_setsid(), as Jakub noticed.
- fix the annotation in selinux_sctp_assoc_request(), as Richard Noticed.

kselftests/net: add missed tests to Makefile
When generating the selftest to another folder, some tests are missing
as they are not added in Makefile. e.g.
make -C tools/testing/selftests/ install \
TARGETS="net" INSTALL_PATH=/tmp/kselftests
These pathset add them separately to make the Fixes tags less. It would
also make the stable tree or downstream backport easier.
If you think there is no need to add the Fixes tag for this minor issue.
I can repost a new patch and merge all the fixes together.

Convert the 9p filesystem to use the netfs helper lib to handle readpage,
readahead and write_begin, converting those into a common issue_op for the
filesystem itself to handle. The netfs helper lib also handles reading
from fscache if a cache is available, and interleaving reads from both
sources.
This change also switches from the old fscache I/O API to the new one,
meaning that fscache no longer keeps track of netfs pages and instead does
async DIO between the backing files and the 9p file pagecache. As a part
of this change, the handling of PG_fscache changes. It now just means that
the cache has a write I/O operation in progress on a page (PG_locked
is used for a read I/O op).
Note that this is a cut-down version of the fscache rewrite and does not
change any of the cookie and cache coherency handling.
Changes
=======
ver #4:
- Rebase on top of folios.
- Don't use wait_on_page_bit_killable().
ver #3:
- v9fs_req_issue_op() needs to terminate the subrequest.
- v9fs_write_end() needs to call SetPageUptodate() a bit more often.
- It's not CONFIG_{AFS,V9FS}_FSCACHE[1]
- v9fs_init_rreq() should take a ref on the p9_fid and the cleanup should
drop it [from Dominique Martinet].

On m68k:
In function ‘prestera_hw_build_tests’,
inlined from ‘prestera_hw_switch_init’ at drivers/net/ethernet/marvell/prestera/prestera_hw.c:788:2:
././include/linux/compiler_types.h:335:38: error: call to ‘__compiletime_assert_345’ declared with attribute error: BUILD_BUG_ON failed: sizeof(struct prestera_msg_switch_attr_req) != 16
...
The driver assumes structure members are naturally aligned, but does not
add explicit padding, thus breaking architectures where integral values
are not always naturally aligned (e.g. on m68k, __alignof(int) is 2, not
4).

This patch allows to use 0 for `coal->rx_coalesce_usecs` param to
disable rx irq coalescing.
Previously we could enable rx irq coalescing via ethtool
(For ex: `ethtool -C eth0 rx-usecs 2000`) but we couldn't disable
it because this part rejects 0 value:
if (!coal->rx_coalesce_usecs)
return -EINVAL;
