07744f2ac0 bus: Optionally include TI sysc driver in SPL/TPL
The TI sysc bus driver is required to allow access to the SPI bus on
am335x platforms. To support SPI boot this driver needs to be enabled in
the SPL/TPL as appropriate.

dec64d55af dm: core: Fix iteration over driver_info records
We should only perform additional iteration steps when needed to
initialize the parent of a device. Other binding errors (such as a
missing driver) should not lead to additional iteration steps.

Unnecessary iteration steps can cause issues when memory is tightly
constrained (such as in the TPL/SPL) since device_bind_by_name()
unconditionally allocates memory for a struct udevice. On the SanCloud
BBE this led to boot failure caused by memory exhaustion in the SPL
when booting from SPI flash.

d1559435d7 net: macb: Fix race caused by flushing unwanted descriptors
The rx descriptor list is in cached memory, and there may be multiple
descriptors per cache-line. After reclaim_rx_buffers marks a descriptor
as unused it does a cache flush, which causes the entire cache-line to
be written to memory, which may override other descriptors in the same
cache-line that the controller may have written to.

The fix skips freeing descriptors that are not the last in a cache-line,
and if the freed descriptor is the last one in a cache-line, it marks
all the descriptors in the cache-line as unused.
This is similarly to what is done in drivers/net/fec_mxc.c

In my case this bug caused tftpboot to fail some times when other
packets are sent to u-boot in addition to the ongoing tftp (e.g. ping).
The driver would stop receiving new packets because it is waiting
on a descriptor that is marked unused, when in reality the descriptor
contains a new unprocessed packet but while freeing the previous buffer
descriptor & flushing the cache, the driver accidentally marked the
descriptor as unused.

0686968639 net: deal with fragment-overlapping-two-holes case
With a suitable sequence of malicious packets, it's currently possible
to get a hole descriptor to contain arbitrary attacker-controlled
contents, and then with one more packet to use that as an arbitrary
write vector.

While one could possibly change the algorithm so we instead loop over
all holes, and in each hole puts as much of the current fragment as
belongs there (taking care to carefully update the hole list as
appropriate), it's not worth the complexity: In real, non-malicious
scenarios, one never gets overlapping fragments, and certainly not
fragments that would be supersets of one another.

So instead opt for this simple protection: Simply don't allow the
eventual memcpy() to write beyond the last_byte of the current hole.

087648b5df net: tftp: sanitize tftp block size, especially for TX
U-Boot does not support IP fragmentation on TX (and unless
CONFIG_IP_DEFRAG is set, neither on RX). So the blocks we send must
fit in a single ethernet packet.

Currently, if tftpblocksize is set to something like 5000 and I
tftpput a large enough file, U-Boot crashes because we overflow
net_tx_packet (which only has room for 1500 bytes plus change).

Similarly, if tftpblocksize is set to something larger than what we
can actually receive (e.g. 50000, with NET_MAXDEFRAG being 16384), any
tftp get just hangs because we never receive any packets.

06653c7010 net: fix ip_len in reassembled IP datagram
For some reason, the ip_len field in a reassembled IP datagram is set
to just the size of the payload, but it should be set to the value it
would have had if the datagram had never been fragmented in the first
place, i.e. size of payload plus size of IP header.

That latter value is currently returned correctly via the "len"
variable. And before entering net_defragment(), len does have the
value ntohs(ip->ip_len), so if we're not dealing with a
fragment (so net_defragment leaves *len alone), that relationship of
course also holds after the net_defragment() call.

The only use I can find of ip->ip_len after the net_defragment call is
the ntohs(ip->udp_len) > ntohs(ip->ip_len) sanity check - none of the
functions that are passed the "ip" pointer themselves inspect ->ip_len
but instead use the passed len.

But that sanity check is a bit odd, since the RHS really should be
"ntohs(ip->ip_len) - 20", i.e. the IP payload size.

Now that we've fixed things so that len == ntohs(ip->ip_len) in all
cases, change that sanity check to use len-20 as the RHS.

1817c3824a net: (actually/better) deal with CVE-2022-{30790,30552}
I hit a strange problem with v2022.10: Sometimes my tftp transfer
would seemingly just hang. It only happened for some files. Moreover,
changing tftpblocksize from 65464 to 65460 or 65000 made it work again
for all the files I tried. So I started suspecting it had something to
do with the file sizes and in particular the way the tftp blocks get
fragmented and reassembled.

v2022.01 showed no problems with any of the files or any value of
tftpblocksize.

Looking at what had changed in net.c or tftp.c since January showed
only one remotely interesting thing, b85d130ea0.

So I fired up wireshark on my host to see if somehow one of the
packets would be too small. But no, with both v2022.01 and v2022.10,
the exact same sequence of packets were sent, all but the last of size
1500, and the last being 1280 bytes.

But then it struck me that 1280 is 5*256, so one of the two bytes
on-the-wire is 0 and the other is 5, and when then looking at the code
again the lack of endianness conversion becomes obvious. [ntohs is
both applied to ip->ip_off just above, as well as to ip->ip_len just a
little further down when the "len" is actually computed].

IOWs the current code would falsely reject any packet which happens to
be a multiple of 256 bytes in size, breaking tftp transfers somewhat
randomly, and if it did get one of those "malicious" packets with
ip_len set to, say, 27, it would be seen by this check as being 6912
and hence not rejected.

====

Now, just adding the missing ntohs() would make my initial problem go
away, in that I can now download the file where the last fragment ends
up being 1280 bytes. But there's another bug in the code and/or
analysis: The right-hand side is too strict, in that it is ok for the
last fragment not to have a multiple of 8 bytes as payload - it really
must be ok, because nothing in the IP spec says that IP datagrams must
have a multiple of 8 bytes as payload. And comments in the code also
mention this.

To fix that, replace the comparison with <= IP_HDR_SIZE and add
another check that len is actually a multiple of 8 when the "more
fragments" bit is set - which it necessarily is for the case where
offset8 ends up being 0, since we're only called when

  (ip_off & (IP_OFFS | IP_FLAGS_MFRAG)).

====

So, does this fix CVE-2022-30790 for real? It certainly correctly
rejects the POC code which relies on sending a packet of size 27 with
the MFRAG flag set. Can the attack be carried out with a size 27
packet that doesn't set MFRAG (hence must set a non-zero fragment
offset)? I dunno. If we get a packet without MFRAG, we update
h->last_byte in the hole we've found to be start+len, hence we'd enter
one of

	if ((h >= thisfrag) && (h->last_byte <= start + len)) {

or

	} else if (h->last_byte <= start + len) {

and thus won't reach any of the

		/* overlaps with initial part of the hole: move this hole */
		newh = thisfrag + (len / 8);

		/* fragment sits in the middle: split the hole */
		newh = thisfrag + (len / 8);

IOW these division are now guaranteed to be exact, and thus I think
the scenario in CVE-2022-30790 cannot happen anymore.

====

However, there's a big elephant in the room, which has always been
spelled out in the comments, and which makes me believe that one can
still cause mayhem even with packets whose payloads are all 8-byte
aligned:

    This code doesn't deal with a fragment that overlaps with two
    different holes (thus being a superset of a previously-received
    fragment).

Suppose each character below represents 8 bytes, with D being already
received data, H being a hole descriptor (struct hole), h being
non-populated chunks, and P representing where the payload of a just
received packet should go:

  DDDHhhhhDDDDHhhhDDDD
        PPPPPPPPP

I'm pretty sure in this case we'd end up with h being the first hole,
enter the simple

	} else if (h->last_byte <= start + len) {
		/* overlaps with final part of the hole: shorten this hole */
		h->last_byte = start;

case, and thus in the memcpy happily overwrite the second H with our
chosen payload. This is probably worth fixing...

ad359d89ec net: compare received length to sizeof(ip_hdr), not sizeof(ip_udp_hdr)
While the code mostly/only handles UDP packets, it's possible for the
last fragment of a fragmented UDP packet to be smaller than 28 bytes;
it can be as small as 21 bytes (an IP header plus one byte of
payload). So until we've performed the defragmentation step and thus
know whether we're now holding a full packet, we should only check for
the existence of the fields in the ip header, i.e. that there are at
least 20 bytes present.

In practice, we always seem to be handed a "len" of minimum 60 from the
device layer, i.e. minimal ethernet frame length minus FCS, so this is
mostly theoretical.

After we've fetched the header's claimed length and used that to
update the len variable, check that the header itself claims to be the
minimal possible length.

This is probably how CVE-2022-30552 should have been dealt with in the
first place, because net_defragment() is not the only place that wants
to know the size of the IP datagram payload: If we receive a
non-fragmented ICMP packet, we pass "len" to receive_icmp() which in
turn may pass it to ping_receive() which does

  compute_ip_checksum(icmph, len - IP_HDR_SIZE)

and due to the signature of compute_ip_checksum(), that would then
lead to accessing ~4G of address space, very likely leading to a
crash.

e9d3fc7e46 net: dwc_eth_qos: Add support for bulk RX descriptor cleaning
Add new desc_per_cacheline property which lets a platform run RX descriptor
cleanup after every power-of-2 - 1 received packets instead of every packet.
This is useful on platforms where (axi_bus_width EQOS_AXI_WIDTH_n * DMA DSL
inter-descriptor word skip count + DMA descriptor size) is less than cache
line size, which necessitates packing multiple DMA descriptors into single
cache line.

In case of TX descriptors, this is not a problem, since the driver always
does synchronous TX, i.e. the TX descriptor is always written, flushed and
polled for completion in eqos_send().

In case of RX descriptors, it is necessary to update their status in bulk,
i.e. after the entire cache line worth of RX descriptors has been used up
to receive data.

bd1e195421 ram: ast2600: Improve ddr4 timing and signal quality
Adjust the following settings to get better timing and signal quality.

1. write DQS/DQ delay
- 1e6e2304[0]
- 1e6e2304[15:8]

2. read DQS/DQ delay
- 0x1e6e0298[0]
- 0x1e6e0298[15:8]

3. CLK/CA timing
- 0x1e6e01a8[31]

4. Read and write termination
- change RTT_ROM from 40 ohm to 48 ohm (MR1[10:8])
- change RTT_PARK from disable to 48 ohm (MR5[8:6])
- change RTT_WR from 120 ohm to disable (MR2[11:9])
- change PHY ODT from 40 ohm to 80 ohm (0x1e6e0130[10:8])

Note1: Both DDR-PHY and DDR controller have their own registers for DDR4
Mode Registers (MR0~MR6).  This patch introduces macros to synchronize
the MR value on both sides.

Note2: the waveform meansurement can be found in item #21 of Aspeed
AST26x0 Application note (AP note).

581df347db ram: ast2600: Fix incorrect statement of the register polling
The condition "~data" in the if-statement is a typo.  The original
intention is to poll if SDRAM_PHYCTRL0_INIT bit equals to 0. So use
"data == 0" for instead.

Besides, the bit[1] of "phy_status" register is hardwired to
SDRAM_PHYCTRL0_INIT (with inverse logic). Since SDRAM_PHYCTRL0_INIT has
already done, remove the unnecessary checking of phy_status[1].

7dfcf2a57f cmd: fdt: Fix iteration over elements above index 1 in fdt get
Always increment both the iterator and pointer into the string
property value by length of the current element + 1 (to cater
for the string delimiter), otherwise the element extracted from
the string property value would be extracted from an offset that
is multiple of the length of the first element, instead of sum
of element lengths until select index.

This fixes 'fdt get value' operation for index above 1 (counting
from index 0).
