If a transaction is aborted, we should mark the to-be-released NEWSET dead,
just like commit path does for DEL and DESTROYSET commands.
In both cases all remaining elements will be released via
set->ops->destroy().
The existing abort code does NOT post the actual release to the work queue.
Also the entire __nf_tables_abort() function is wrapped in gc_seq
begin/end pair.
Therefore, async gc worker will never try to release the pending set
elements, as gc sequence is always stale.
It might be possible to speed up transaction aborts via work queue too,
this would result in a race and a possible use-after-free.
So fix this before it becomes an issue.

[ Upstream commit 3084b58bfd0b9e4b5e034f31f31b42977db35f12 ]
The netlink interface for major and minor version numbers doesn't actually
return the major and minor version numbers.
It reports a u32 that contains the (major, minor, update, alpha1)
components as the major version number, and then alpha2 as the minor
version number.
For whatever reason, the u32 byte order was reversed (ntohl): maybe it was
assumed that the encoded value was a single big-endian u32, and alpha2 was
the minor version.
The correct way to get the supported NC-SI version from the network
controller is to parse the Get Version ID response as described in 8.4.44
of the NC-SI spec[1].
Get Version ID Response Packet Format
Bits
+--------+--------+--------+--------+
Bytes | 31..24 | 23..16 | 15..8 | 7..0 |
+-------+--------+--------+--------+--------+
| 0..15 | NC-SI Header |
+-------+--------+--------+--------+--------+
| 16..19| Response code | Reason code |
+-------+--------+--------+--------+--------+
|20..23 | Major | Minor | Update | Alpha1 |
+-------+--------+--------+--------+--------+
|24..27 | reserved | Alpha2 |
+-------+--------+--------+--------+--------+
| .... other stuff .... |
The major, minor, and update fields are all binary-coded decimal (BCD)
encoded [2]. The spec provides examples below the Get Version ID response
format in section 8.4.44.1, but for practical purposes, this is an example
from a live network card:
root@bmc:~# ncsi-util 0x15
NC-SI Command Response:
cmd: GET_VERSION_ID(0x15)
Response: COMMAND_COMPLETED(0x0000) Reason: NO_ERROR(0x0000)
Payload length = 40
20: 0xf1 0xf1 0xf0 0x00 <<<<<<<<< (major, minor, update, alpha1)
24: 0x00 0x00 0x00 0x00 <<<<<<<<< (_, _, _, alpha2)
28: 0x6d 0x6c 0x78 0x30
32: 0x2e 0x31 0x00 0x00
36: 0x00 0x00 0x00 0x00
40: 0x16 0x1d 0x07 0xd2
44: 0x10 0x1d 0x15 0xb3
48: 0x00 0x17 0x15 0xb3
52: 0x00 0x00 0x81 0x19
This should be parsed as "1.1.0".
"f" in the upper-nibble means to ignore it, contributing zero.
If both nibbles are "f", I think the whole field is supposed to be ignored.
Major and minor are "required", meaning they're not supposed to be "ff",
but the update field is "optional" so I think it can be ff. I think the
simplest thing to do is just set the major and minor to zero instead of
juggling some conditional logic or something.
bcd2bin() from "include/linux/bcd.h" seems to assume both nibbles are 0-9,
so I've provided a custom BCD decoding function.
Alpha1 and alpha2 are ISO/IEC 8859-1 encoded, which just means ASCII
characters as far as I can tell, although the full encoding table for
non-alphabetic characters is slightly different (I think).
I imagine the alpha fields are just supposed to be alphabetic characters,
but I haven't seen any network cards actually report a non-zero value for
either.
If people wrote software against this netlink behavior, and were parsing
the major and minor versions themselves from the u32, then this would
definitely break their code.
