Jiri Slaby reported that building the kernel with AR=gcc-ar shows:
/usr/bin/ar terminated with signal 13 [Broken pipe]
Nathan Chancellor reported the latest AR=llvm-ar shows:
error: write on a pipe with no reader
The latter occurs since LLVM commit 51b557adc131 ("Add an error message
to the default SIGPIPE handler").
The resulting vmlinux is correct, but it is better to silence it.
'head -n1' exits after reading the first line, so the pipe is closed.
Use 'sed -n 1p' to eat the stream till the end.

We want to leverage keyring to store sensitive keys, and then use those
keys for symmetric encryption via the crypto API. Among the key types we
wish to support are: user, logon, encrypted, and trusted.
User key types are already able to have their data copied to user space,
but logon does not support this. Further, trusted and encrypted keys will
return their encrypted data back to user space on read, which does not
make them ideal for symmetric encryption.
To support symmetric encryption for these key types, add a new
ALG_SET_KEY_BY_KEY_SERIAL setsockopt() option to the crypto API. This
allows users to pass a key_serial_t to the crypto API to perform
symmetric encryption. The behavior is the same as ALG_SET_KEY, but
the crypto key data is copied in kernel space from a keyring key,
which allows for the support of logon, encrypted, and trusted key types.
Keyring keys must have the KEY_(POS|USR|GRP|OTH)_SEARCH permission set
to leverage this feature. This follows the asymmetric_key type where key
lookup calls eventually lead to keyring_search_rcu() without the
KEYRING_SEARCH_NO_CHECK_PERM flag set.

====================
Netfilter updates for net-next
1) Move struct nft_payload_set definition to .c file where it is
only used.
2) Shrink transport and inner header offset fields in the nft_pktinfo
structure to 16-bits, from Florian Westphal.
3) Get rid of nft_objref Kbuild toggle, make it built-in into
nf_tables. This expression is used to instantiate conntrack helpers
in nftables. After removing the conntrack helper auto-assignment
toggle it this feature became more important so move it to the nf_tables
core module. Also from Florian.
4) Extend the existing function to calculate payload inner header offset
to deal with the GRE and IPIP transport protocols.
6) Add inner expression support for nf_tables. This new expression
provides a packet parser for tunneled packets which uses a userspace
description of the expected inner headers. The inner expression
invokes the payload expression (via direct call) to match on the
inner header protocol fields using the inner link, network and
transport header offsets.
An example of the bytecode generated from userspace to match on
IP source encapsulated in a VxLAN packet:
# nft --debug=netlink add rule netdev x y udp dport 4789 vxlan ip saddr 1.2.3.4
netdev x y
[ meta load l4proto => reg 1 ]
[ cmp eq reg 1 0x00000011 ]
[ payload load 2b @ transport header + 2 => reg 1 ]
[ cmp eq reg 1 0x0000b512 ]
[ inner type vxlan hdrsize 8 flags f [ meta load protocol => reg 1 ] ]
[ cmp eq reg 1 0x00000008 ]
[ inner type vxlan hdrsize 8 flags f [ payload load 4b @ network header + 12 => reg 1 ] ]
[ cmp eq reg 1 0x04030201 ]
7) Store inner link, network and transport header offsets in percpu
area to parse inner packet header once only. Matching on a different
tunnel type invalidates existing offsets in the percpu area and it
invokes the inner tunnel parser again.
8) Add support for inner meta matching. This support for
NFTA_META_PROTOCOL, which specifies the inner ethertype, and
NFT_META_L4PROTO, which specifies the inner transport protocol.
9) Extend nft_inner to parse GENEVE optional fields to calculate the
link layer offset.
10) Update inner expression so tunnel offset points to GRE header
to normalize tunnel header handling. This also allows to perform
different interpretations of the GRE header from userspace.

ionic: VF attr replay and other updates
For better VF management when a FW update restart or a FW crash recover is

Newer FW offers more packet processing offloads, so we now support them in

When expanding a file system using online resize, various fields in
the superblock (e.g., s_blocks_count, s_inodes_count, etc.) change.
To update the backup superblocks, the online resize uses the function
update_backups() in fs/ext4/resize.c. This function was not updating
the checksum field in the backup superblocks. This wasn't a big deal
previously, because e2fsck didn't care about the checksum field in the
backup superblock. (And indeed, update_backups() goes all the way
back to the ext3 days, well before we had support for metadata
checksums.)
However, there is an alternate, more general way of updating
superblock fields, ext4_update_primary_sb() in fs/ext4/ioctl.c. This
function does check the checksum of the backup superblock, and if it
doesn't match will mark the file system as corrupted. That was
clearly not the intent, so avoid to aborting the resize when a bad
superblock is found.
In addition, teach update_backups() to properly update the checksum in
the backup superblocks. We will eventually want to unify
updapte_backups() with the infrasture in ext4_update_primary_sb(), but
that's for another day.
Note: The problem has been around for a while; it just didn't really
matter until ext4_update_primary_sb() was added by commit bbc605cdb1
("ext4: implement support for get/set fs label"). And it became
trivially easy to reproduce after commit 827891a38a ("ext4: update
the s_overhead_clusters in the backup sb's when resizing") in v6.0.
