Bpftool creates a new JSON object for writing program metadata in plain
text mode, regardless of metadata being present or not. Then this writer
is freed if any metadata has been found and printed, but it leaks
otherwise. We cannot destroy the object unconditionally, because the
destructor prints an undesirable line break. Instead, make sure the
writer is created only after we have found program metadata to print.
Found with valgrind.

This series is a followup to the delayed devlink notification scheme.
I removed the impossible notifications together with attempt to annotate
various calls in order to mark them as pre/post devlink_register().
Other notifications are called before and after delvink_register() so

If writeback I/O to a COW extent fails, the COW fork blocks are
punched out and the data fork blocks left alone. It is possible for
COW fork blocks to overlap non-shared data fork blocks (due to
cowextsz hint prealloc), however, and writeback unconditionally maps
to the COW fork whenever blocks exist at the corresponding offset of
the page undergoing writeback. This means it's quite possible for a
COW fork extent to overlap delalloc data fork blocks, writeback to
convert and map to the COW fork blocks, writeback to fail, and
finally for ioend completion to cancel the COW fork blocks and leave
stale data fork delalloc blocks around in the inode. The blocks are
effectively stale because writeback failure also discards dirty page
state.
If this occurs, it is likely to trigger assert failures, free space
accounting corruption and failures in unrelated file operations. For
example, a subsequent reflink attempt of the affected file to a new
target file will trip over the stale delalloc in the source file and
fail. Several of these issues are occasionally reproduced by
generic/648, but are reproducible on demand with the right sequence
of operations and timely I/O error injection.
To fix this problem, update the ioend failure path to also punch out
underlying data fork delalloc blocks on I/O error. This is analogous
to the writeback submission failure path in xfs_discard_page() where
we might fail to map data fork delalloc blocks and consistent with
the successful COW writeback completion path, which is responsible
for unmapping from the data fork and remapping in COW fork blocks.

Recent change to use tp/syscalls/sys_enter_nanosleep for perf_buffer
selftests causes this selftest to fail on 4.9 kernel in libbpf CI ([0]):
libbpf: prog 'handle_sys_enter': failed to attach to perf_event FD 6: Invalid argument
libbpf: prog 'handle_sys_enter': failed to attach to tracepoint 'syscalls/sys_enter_nanosleep': Invalid argument
It's not exactly clear why, because perf_event itself is created for
this tracepoint, but I can't even compile 4.9 kernel locally, so it's
hard to figure this out. If anyone has better luck and would like to
help investigating this, I'd really appreciate this.
For now, unblock CI by switching back to raw_syscalls/sys_enter, but reduce
amount of unnecessary samples emitted by filter by process ID. Use
explicit ARRAY map for that to make it work on 4.9 as well, because
global data isn't yet supported there.

====================
sctp: enhancements for the verification tag
This patchset is to address CVE-2021-3772:
A flaw was found in the Linux SCTP stack. A blind attacker may be able to
kill an existing SCTP association through invalid chunks if the attacker
knows the IP-addresses and port numbers being used and the attacker can
send packets with spoofed IP addresses.
This is caused by the missing VTAG verification for the received chunks
and the incorrect vtag for the ABORT used to reply to these invalid
chunks.
This patchset is to go over all processing functions for the received
chunks and do:
1. Make sure sctp_vtag_verify() is called firstly to verify the vtag from
the received chunk and discard this chunk if it fails. With some
exceptions:
a. sctp_sf_do_5_1B_init()/5_2_2_dupinit()/9_2_reshutack(), processing
INIT chunk, as sctphdr vtag is always 0 in INIT chunk.
b. sctp_sf_do_5_2_4_dupcook(), processing dupicate COOKIE_ECHO chunk,
as the vtag verification will be done by sctp_tietags_compare() and
then it takes right actions according to the return.
c. sctp_sf_shut_8_4_5(), processing SHUTDOWN_ACK chunk for cookie_wait
and cookie_echoed state, as RFC demand sending a SHUTDOWN_COMPLETE
even if the vtag verification failed.
d. sctp_sf_ootb(), called in many types of chunks for closed state or
no asoc, as the same reason to c.
2. Always use the vtag from the received INIT chunk to make the response
ABORT in sctp_ootb_pkt_new().
3. Fix the order for some checks and add some missing checks for the
received chunk.
This patch series has been tested with SCTP TAHI testing to make sure no
regression caused on protocol conformance.

sctp_sf_ootb() is called when processing DATA chunk in closed state,
and many other places are also using it.
The vtag in the chunk's sctphdr should be verified, otherwise, as
later in chunk length check, it may send abort with the existent
asoc's vtag, which can be exploited by one to cook a malicious
chunk to terminate a SCTP asoc.
When fails to verify the vtag from the chunk, this patch sets asoc
to NULL, so that the abort will be made with the vtag from the
received chunk later.

1. In closed state: in sctp_sf_do_5_1D_ce():
When asoc is NULL, making packet for abort will use chunk's vtag
in sctp_ootb_pkt_new(). But when asoc exists, vtag from the chunk
should be verified before using peer.i.init_tag to make packet
for abort in sctp_ootb_pkt_new(), and just discard it if vtag is
not correct.
2. In the other states: in sctp_sf_do_5_2_4_dupcook():
asoc always exists, but duplicate cookie_echo's vtag will be
handled by sctp_tietags_compare() and then take actions, so before
that we only verify the vtag for the abort sent for invalid chunk
length.

Currently INIT_ACK chunk in non-cookie_echoed state is processed in
sctp_sf_discard_chunk() to send an abort with the existent asoc's
vtag if the chunk length is not valid. But the vtag in the chunk's
sctphdr is not verified, which may be exploited by one to cook a
malicious chunk to terminal a SCTP asoc.
sctp_sf_discard_chunk() also is called in many other places to send
an abort, and most of those have this problem. This patch is to fix
it by sending abort with the existent asoc's vtag only if the vtag
from the chunk's sctphdr is verified in sctp_sf_discard_chunk().
Note on sctp_sf_do_9_1_abort() and sctp_sf_shutdown_pending_abort(),
the chunk length has been verified before sctp_sf_discard_chunk(),
so replace it with sctp_sf_discard(). On sctp_sf_do_asconf_ack() and
sctp_sf_do_asconf(), move the sctp_chunk_length_valid check ahead of
sctp_sf_discard_chunk(), then replace it with sctp_sf_discard().

sctp_sf_do_5_2_2_dupinit():
chunk length check should be done before any checks that may cause

from init_hdr in sctp_ootb_pkt_new().
2. In shutdown_ack_sent state: in sctp_sf_do_9_2_reshutack():
The same checks as does in sctp_sf_do_5_2_2_dupinit() is needed

Currently Linux SCTP uses the verification tag of the existing SCTP
asoc when failing to process and sending the packet with the ABORT
chunk. This will result in the peer accepting the ABORT chunk and
removing the SCTP asoc. One could exploit this to terminate a SCTP
asoc.
This patch is to fix it by always using the initiate tag of the
received INIT chunk for the ABORT chunk to be sent.

Christoph Paasch reports [1] about incorrect skb->truesize
after skb_expand_head() call in ip6_xmit.
This may happen because of two reasons:
- skb_set_owner_w() for newly cloned skb is called too early,
before pskb_expand_head() where truesize is adjusted for (!skb-sk) case.
- pskb_expand_head() does not adjust truesize in (skb->sk) case.
In this case sk->sk_wmem_alloc should be adjusted too.

Don't write directly to netdev->dev_addr.
More conversions, mostly in usb/net.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
