arm64: zynqmp: dynamically mark r5 cores as used
When Linux boot takes over control of the pmu

rpu cores. The Xilinx zynqmp fsbl prevents switching off those cores by
marking rpu cores as 'used' when loading code partitions to those cores.
The current u-boot SPL is missing this behaviour, which results in
halting rpu cores during Linux boot.

The rx descriptor list is in cached memory, and there may be multiple

be written to memory, which may override other descriptors in the same

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.

In my case this bug caused tftpboot to fail some times when other

The driver would stop receiving new packets because it is waiting
on a descriptor that is marked unused, when in reality the descriptor

While one could possibly change the algorithm so we instead loop over

appropriate), it's not worth the complexity: In real, non-malicious

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.

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, b85d130ea0ca.
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
/* 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...

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.

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

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].

binman: bintool: remove btool_ prefix from btool names
The binary is looked on the system by the suffix of the packer class.
This means binman was looking for btool_gzip on the system and not gzip.
Since a btool can have its btool_ prefix missing but its module and
binary presence on the system appropriately found, there's no need to
actually keep this prefix after listing all possible btools, so let's
remove it.
This fixes gzip btool by letting Bintool.find_bintool_class handle the
missing prefix and still return the correct class which is then init
with gzip name instead of btool_gzip.
Additionally, there was an issue with the cached module global variable.
The variable only stores the module and not the associated class name
when calling find_bintool_class.
This means that when caching the module on the first call to
find_bintool_class, class_name would be set to Bintoolbtool_gzip but the
module_name gzip only, adding the module in the gzip key in the module
dictionary. When hitting the cache on next calls, the gzip key would be
found, so its value (the module) is used. However the default class_name
(Bintoolgzip) is used, failing the getattr call.
Instead, let's enforce the same class name: Bintool<packer>, whatever
the filename it is contained in.
The sync of device-tree/bindings in 11a48a5a18c6 ("Linux 5.6-rc2") causes
Ethernet to break on some GXBB boards; the PHY seems to need proper reset
timing to function in u-boot and Linux. Re-add the old PHY reset binding
for dwmac until we support new bindings in the PHY node. This borrows the
same fix applied to the Odroid C2 board [0].
Implement setbrg in amlogic/meson serial device with driver model
similar to how the meson_uart.c driver does it in Linux. Also
configure (probe) the serial device with the new reg5 register.
