f574633529 net: checksum: Introduce fine control over checksum type
At present net_checksum_calculate() blindly calculates all types of
checksums (IP, TCP, UDP). Some NICs may have a per type setting in
their BDs to control what checksum should be offloaded. To support
such hardware behavior, introduce a 'csum_flag' parameter to the
net_checksum_calculate() API to allow fine control over what type
checksum is calculated.

Existing users of this API are updated accordingly.

d97f11590a net: checksum: Add IP header checksum calculation
At present net_checksum_calculate() only calculates TCP/UDP checksum
in an IP packet, but assumes the IP header checksum to be provided
by the software, e.g.: Linux kernel always calculates the IP header
checksum. However this might not always be the case, e.g.: for an IP
checksum offload enabled stack like VxWorks, the IP header checksum
can be zero.

This adds the checksum calculation of the IP header.

0dcf0c0aee net: checksum: Skip fragmented IP packets
To calculate the TCP/UDP checksum we need the whole datagram. Unless
the hardware has some logic to collect all fragments before sending
the whole datagram first, it can only be done by the network stack,
which is normally the case for the NICs we have seen so far.

Skip these fragmented IP packets to avoid checksum corruption.

831734cce6 net: Fix handling of id in netdev_add and netdev_del
CLI -netdev accumulates in option group "netdev".

Before commit 08712fcb85 "net: Track netdevs in NetClientState rather
than QemuOpt", netdev_add added to the option group, and netdev_del
removed from it, both HMP and QMP.  Thus, every netdev had a
corresponding QemuOpts in this option group.

Commit 08712fcb85 dropped this for QMP netdev_add and both netdev_del.
Now a netdev has a corresponding QemuOpts only when it was created
with CLI or HMP.  Two issues:

* QMP and HMP netdev_del can leave QemuOpts behind, breaking HMP
  netdev_add.  Reproducer:

    $ qemu-system-x86_64 -S -display none -nodefaults -monitor stdio
    QEMU 5.1.92 monitor - type 'help' for more information
    (qemu) netdev_add user,id=net0
    (qemu) info network
    net0: index=0,type=user,net=10.0.2.0,restrict=off
    (qemu) netdev_del net0
    (qemu) info network
    (qemu) netdev_add user,id=net0
    upstream-qemu: Duplicate ID 'net0' for netdev
    Try "help netdev_add" for more information

  Fix by restoring the QemuOpts deletion in qmp_netdev_del(), but with
  a guard, because the QemuOpts need not exist.

* QMP netdev_add loses its "no duplicate ID" check.  Reproducer:

    $ qemu-system-x86_64 -S -display none -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 92, "minor": 1, "major": 5}, "package": "v5.2.0-rc2-1-g02c1f0142c"}, "capabilities": ["oob"]}}
    {"execute": "qmp_capabilities"}
    {"return": {}}
    {"execute": "netdev_add", "arguments": {"type": "user", "id":"net0"}}
    {"return": {}}
    {"execute": "netdev_add", "arguments": {"type": "user", "id":"net0"}}
    {"return": {}}

  Fix by adding a duplicate ID check to net_client_init1() to replace
  the lost one.  The check is redundant for callers where QemuOpts
  still checks, i.e. for CLI and HMP.

3a67cbe619 hw/sd: ssi-sd: Add a state representing Nac
Per the "Physical Layer Specification Version 8.00" chapter 7.5.2,
"Data Read", there is a minimum 8 clock cycles (Nac) after the card
response and before data block shows up on the data out line. This
applies to both single and multiple block read operations.

Current implementation of single block read already satisfies the
timing requirement as in the RESPONSE state after all responses are
transferred the state remains unchanged. In the next 8 clock cycles
it jumps to DATA_START state if data is ready.

However we need an explicit state when expanding our support to
multiple block read in the future. Let's add a new state PREP_DATA
explicitly in the ssi-sd state machine to represent Nac.

Note we don't change the single block read state machine to let it
jump from RESPONSE state to DATA_START state as that effectively
generates a 16 clock cycles Nac, which might not be safe. As the
spec says the maximum Nac shall be calculated from several fields
encoded in the CSD register, we don't want to bother updating CSD
to ensure our Nac is within range to complicate things.

Per the SD spec, a valid data block is suffixed with a 16-bit CRC
generated by the standard CCITT polynomial x16+x12+x5+1. This part
is currently missing in the ssi-sd state machine. Without it, all
data block transfer fails in guest software because the expected
CRC16 is missing on the data out line.

e9d28020d2 hw/sd: sd: Drop sd_crc16()
commit f6fb1f9b31 ("sdcard: Correct CRC16 offset in sd_function_switch()")
changed the 16-bit CRC to be stored at offset 64. In fact, this CRC
calculation is completely wrong. From the original codes, it wants
to calculate the CRC16 of the first 64 bytes of sd->data[], however
passing 64 as the `width` to sd_crc16() actually counts 256 bytes
starting from the `message` for the CRC16 calculation, which is not
what we want.

Besides that, it seems existing sd_crc16() algorithm does not match
the SD spec, which says CRC16 is the CCITT one but the calculation
does not produce expected result. It turns out the CRC16 was never
transferred outside the sd core, as in sd_read_byte() we see:

    if (sd->data_offset >= 64)
        sd->state = sd_transfer_state;

Given above reasons, let's drop it.

281c5c95b2 hw/sd: ssi-sd: Fix incorrect card response sequence
Per the "Physical Layer Specification Version 8.00" chapter 7.5.1,
"Command/Response", there is a minimum 8 clock cycles (Ncr) before
the card response shows up on the data out line. However current
implementation jumps directly to the sending response state after
all 6 bytes command is received, which is a spec violation.

Add a new state PREP_RESP in the ssi-sd state machine to handle it.

ccd3b3b811 qemu-option: warn for short-form boolean options
Options such as "server" or "nowait", that are commonly found in -chardev,
are sugar for "server=on" and "wait=off".  This is quite surprising and
also does not have any notion of typing attached.  It is even possible to
do "-device e1000,noid" and get a device with "id=off".

Deprecate it and print a warning when it is encountered.  In general,
this short form for boolean options only seems to be in wide use for
-chardev and -spice.

afd736252f qemu-option: move help handling to get_opt_name_value
Right now, help options are parsed normally and then checked
specially in opt_validate, but only if coming from
qemu_opts_parse_noisily.  has_help_option does the check on its own.

opt_validate() has two callers: qemu_opt_set(), which passes null and is
therefore unaffected, and opts_do_parse(), which is affected.

opts_do_parse() is called by qemu_opts_do_parse(), which passes null and
is therefore unaffected, and opts_parse().

opts_parse() is called by qemu_opts_parse() and qemu_opts_set_defaults(),
which pass null and are therefore unaffected, and
qemu_opts_parse_noisily().

Move the check from opt_validate to the parsing workhorse of QemuOpts,
get_opt_name_value.  This will come in handy in the next patch, which
will raise a warning for "-object memory-backend-ram,share" ("flag" option
with no =on/=off part) but not for "-object memory-backend-ram,help".

As a result:

- opts_parse and opts_do_parse do not return an error anymore
  when help is requested; qemu_opts_parse_noisily does not have
  to work around that anymore.

- various crazy ways to request help are not recognized anymore:
  - "help=..."
  - "nohelp" (sugar for "help=off")
  - "?=..."
  - "no?" (sugar for "?=off")

- "help" would be recognized as help request even if there is a (foolishly
  named) parameter "help".  No such parameters exist, though.

63758d1073 qemu-option: clean up id vs. list->merge_lists
Looking at all merge-lists QemuOptsList, here is how they access their
QemuOpts:

reopen_opts in qemu-io-cmds.c ("qemu-img reopen -o")
	qemu_opts_find(&reopen_opts, NULL)

empty_opts in qemu-io.c ("qemu-io open -o")
	qemu_opts_find(&empty_opts, NULL)

qemu_rtc_opts ("-rtc")
	qemu_find_opts_singleton("rtc")

qemu_machine_opts ("-M")
	qemu_find_opts_singleton("machine")

qemu_action_opts ("-name")
	qemu_opts_foreach->process_runstate_actions

qemu_boot_opts ("-boot")
	in hw/nvram/fw_cfg.c and hw/s390x/ipl.c:
	  QTAILQ_FIRST(&qemu_find_opts("bootopts")->head)
	in softmmu/vl.c:
	  qemu_opts_find(qemu_find_opts("boot-opts"), NULL)

qemu_name_opts ("-name")
	qemu_opts_foreach->parse_name
	parse_name does not use id

qemu_mem_opts ("-m")
	qemu_find_opts_singleton("memory")

qemu_icount_opts ("-icount")
	qemu_opts_foreach->do_configure_icount
	do_configure_icount->icount_configure
	icount_configure does not use id

qemu_smp_opts ("-smp")
	qemu_opts_find(qemu_find_opts("smp-opts"), NULL)

qemu_spice_opts ("-spice")
	QTAILQ_FIRST(&qemu_spice_opts.head)

i.e. they don't need an id.  Sometimes its presence is ignored
(e.g. when using qemu_opts_foreach), sometimes all the options
with the id are skipped, sometimes only the first option on the
command line is considered.  -boot does two different things
depending on who's looking at the options.

With this patch we just forbid id on merge-lists QemuOptsLists; if the
command line still works, it has the same semantics as before.

qemu_opts_create's fail_if_exists parameter is now unnecessary:

- it is unused if id is NULL

- opts_parse only passes false if reached from qemu_opts_set_defaults,
in which case this patch enforces that id must be NULL

- other callers that can pass a non-NULL id always set it to true

Assert that it is true in the only case where "fail_if_exists" matters,
i.e. "id && !lists->merge_lists".  This means that if an id is present,
duplicates are always forbidden, which was already the status quo.

Discounting the case that aborts as it's not user-controlled (it's
"just" a matter of inspecting qemu_opts_create callers), the paths
through qemu_opts_create can be summarized as:

- merge_lists = true: singleton opts with NULL id; non-NULL id fails

- merge_lists = false: always return new opts; non-NULL id fails if dup

cfb5387a1d hmp: remove "change vnc TARGET" command
The HMP command \"change vnc TARGET\" is messy:

- it takes an ugly shortcut to determine if the option has an "id",
with incorrect results if "id=" is not preceded by an unescaped
comma.

- it deletes the existing QemuOpts and does not try to rollback
if the parsing fails (which is not causing problems, but only due to
how VNC options are parsed)

- because it uses the same parsing function as "-vnc", it forces
the latter to not support "-vnc help".

On top of this, it uses a deprecated QMP command, thus getting in
the way of removing the QMP command.  Since the usecase for the
command is not clear, just remove it and send "change vnc password"
directly to the QMP "change-vnc-password" command.
