The XFRMA_SET_MARK_MASK attribute can be set in states (4.19+)
It is optional and the kernel default is 0xffffffff
It is the mask of XFRMA_SET_MARK(a.k.a. XFRMA_OUTPUT_MARK in 4.18)
e.g.
./ip/ip xfrm state add output-mark 0x6 mask 0xab proto esp \
auth digest_null 0 enc cipher_null ''
ip xfrm state
src 0.0.0.0 dst 0.0.0.0
proto esp spi 0x00000000 reqid 0 mode transport
replay-window 0
output-mark 0x6/0xab
auth-trunc digest_null 0x30 0
enc ecb(cipher_null)
anti-replay context: seq 0x0, oseq 0x0, bitmap 0x00000000
sel src 0.0.0.0/0 dst 0.0.0.0/0

The XFRMA_IF_ID attribute is set in policies for them to be
associated with an XFRM interface (4.19+).
Add support for getting/deleting policies with this attribute.
For supporting 'deleteall' the XFRMA_IF_ID attribute needs to be
explicitly copied.

In commit aed63ae1ac ("ip xfrm: support setting/printing XFRMA_IF_ID attribute in states/policies")
I added the ability to set/print the xfrm interface ID without updating
the man page.

While at it, convert xfrm_xfrma_print and xfrm_encap_type_parse to use
the UAPI macros for encap_type as suggested by David Ahern, and add the
UAPI udp.h header (sync'd from ipsec-next to get the TCP_ENCAP_ESPINTCP
definition).

Allow to limit 'ip xfrm {state|policy} list' output to a certain address
family and to delete all states/policies by family.
Although preferred_family was already set in filters, the filter
function ignored it. To enable filtering despite the lack of other
selectors, filter.use has to be set if family is not AF_UNSPEC.

ip xfrm state show currently dumps keys unconditionally. This limits its
use in logging, as security information can be leaked.
This patch adds a nokeys option to ip xfrm ( state show | monitor ), which
prevents the printing of keys. This allows ip xfrm state show to be used
in logging without exposing keys.

This patch adds support for OUTPUT_MARK in xfrm state to exercise the
functionality added by kernel commit 077fbac405bf

v1->v2: Moved the XFRMA_OUTPUT_MARK print after XFRMA_MARK in
xfrm_xfrma_print() as mentioned by Lorenzo
v2->v3: Fix one help formatting error as mentioned by Lorenzo.
Keep mark and output-mark on the same line and add man page info as
mentioned by David.

Enclosed patch fixes inappropriate uses of the .SS macro. Fuller explanation
in the change comment.
There are other problems in these pages that block lifting to
XML-DocBook, most notably in the command synopses. They will take
some creativity to fix. I'm working on it

Subject: [PATCH] Abolish presentation-level misuse of the .SS macro.
This change fixes most (but not all) fatal errors in attempts to lift
the iproute2 manual pages to XML-DocBook. Where .SS is still used it
is a real subsection header, not just a way to outdent and bold text.
Presentation-level instances are turned into .TP calls and tables.
Change ALGO-KEY to ALGO-KEYMAT to make it more obvious that the
keying material might need to contain more than just the key (such
as a salt or nonce value).
List the algorithm names that currently exist in the kernel.
Indicate that for IPComp, the Compression Parameter Index (CPI) is
used as the SPI.
Group the list of mode values by transform protocol.
