Ip6ConfigReadConfigData() reads configuration data from a UEFI variable
and copies the data to another buffer. This change checks that the
length
of the data record being copied does not exceed the size of the source
UEFI variable data buffer.
If the size is exceeded, this change follows existing logic to treat the
variable as corrupted and deletes the variable so it will be set again.

SnpDxe initializes values for MemoryBarIndex and IoBarIndex to 0 and 1
respectively even if calls to PciIo->GetBarAttributes never return
success.
Later, if the BAR is used to perform IO/Mem reads/writes, a potentially
non-existent BAR index may be accessed. This change initializes the
values
to an invalid BAR index (PCI_MAX_BAR) so the condition can be explicitly
checked to avoid an invalid BAR access.

The current SnpDxe implementation registers its ExitBootServices event
notification function (SnpNotifyExitBootServices ()) at TPL_NOTIFY. This
function calls PxeShutdown() which issues an UNDI shutdown operation.
Ultimately, this may invoke Shutdown() in EFI_SIMPLE_NETWORK_PROTOCOL.
The UEFI specification 2.8A Table 27 "TPL Restrictions" restricts the
TPL
for Simple Network Protocol to <= TPL_CALLBACK. In addition, it has been
observed in some 3rd party UNDI drivers to cause an issue further down
the call stack if the TPL is higher than TPL_CALLBACK on invocation.
Therefore, this commit changes the TPL of SnpNotifyExitBootServices() to
TPL_CALLBACK.

Fixes: 9c20342eed
When DHCP is misconfigured on a network segment, such that two DHCP
servers attempt to reply to requests (and therefore race with each other),
the edk2 PXE client can confuse itself.
In PxeBcDhcp4BootInfo() / PxeBcDhcp6BootInfo(), the client may refer to a
DHCP reply packet as an "earlier" packet from the "same" DHCP server, when
in reality both packets are unrelated, and arrive from different DHCP
servers.
While the edk2 PXE client can do nothing to fix this, it should at least
not ASSERT() -- ASSERT() is for catching programming errors (violations of
invariants that are under the control of the programmer). ASSERT()s should
in particular not refer to external data (such as network packets). What's
more, in RELEASE builds, we get NULL pointer references.
Check the problem conditions with actual "if"s, and return
EFI_PROTOCOL_ERROR. This will trickle out to PxeBcLoadBootFile(), and be
reported as "PXE-E99: Unexpected network error".

Message-Id: <20200207010831.9046-30-philmd@redhat.com>
When downloading over TLS, each TLS message ("APP packet") is returned as
a (decrypted) fragment table by EFI_TLS_PROTOCOL.ProcessPacket().
The TlsProcessMessage() function in "NetworkPkg/HttpDxe/HttpsSupport.c"
linearizes the fragment table into a single contiguous data block. The
resultant flat data block contains both TLS headers and data.
The HttpsReceive() function parses the actual application data -- in this
case: decrypted HTTP data -- out of the flattened TLS data block, peeling
off the TLS headers.
The HttpResponseWorker() function in "NetworkPkg/HttpDxe/HttpImpl.c"
propagates this HTTP data outwards, implementing the
EFI_HTTP_PROTOCOL.Response() function.
Now consider the following documentation for EFI_HTTP_PROTOCOL.Response(),
quoted from "MdePkg/Include/Protocol/Http.h":
> It is the responsibility of the caller to allocate a buffer for Body and
> specify the size in BodyLength. If the remote host provides a response
> that contains a content body, up to BodyLength bytes will be copied from
> the receive buffer into Body and BodyLength will be updated with the
> amount of bytes received and copied to Body. This allows the client to
> download a large file in chunks instead of into one contiguous block of
> memory.
Note that, if the caller-allocated buffer is larger than the
server-provided chunk, then the transfer length is limited by the latter.
This is in fact the dominant case when downloading a huge file (for which
UefiBootManagerLib allocated a huge contiguous RAM Disk buffer) in small
TLS messages.
For adjusting BodyLength as described above -- i.e., to the application
data chunk that has been extracted from the TLS message --, the
HttpResponseWorker() function employs the following assignment:
HttpMsg->BodyLength = MIN (Fragment.Len, (UINT32) HttpMsg->BodyLength);
The (UINT32) cast is motivated by the MIN() requirement -- in
"MdePkg/Include/Base.h" -- that both arguments be of the same type.
"Fragment.Len" (NET_FRAGMENT.Len) has type UINT32, and
"HttpMsg->BodyLength" (EFI_HTTP_MESSAGE.BodyLength) has type UINTN.
Therefore a cast is indeed necessary.
Unfortunately, the cast is done in the wrong direction. Consider the
following circumstances:
- "Fragment.Len" happens to be consistently 16KiB, dictated by the HTTPS
Server's TLS stack,
- the size of the file to download is 4GiB + N*16KiB, where N is a
positive integer.
As the download progresses, each received 16KiB application data chunk
brings the *next* input value of BodyLength closer down to 4GiB. The cast
in MIN() always masks off the high-order bits from the input value of
BodyLength, but this is no problem because the low-order bits are nonzero,
therefore the MIN() always permits progress.
However, once BodyLength reaches 4GiB exactly on input, the MIN()
invocation produces a zero value. HttpResponseWorker() adjusts the output
value of BodyLength to zero, and then passes it to HttpParseMessageBody().
HttpParseMessageBody() (in "NetworkPkg/Library/DxeHttpLib/DxeHttpLib.c")
rejects the zero BodyLength with EFI_INVALID_PARAMETER, which is fully
propagated outwards, and aborts the HTTPS download. HttpBootDxe writes the
message "Error: Unexpected network error" to the UEFI console.
For example, a file with size (4GiB + 197MiB) terminates after downloading
just 197MiB.
Invert the direction of the cast: widen "Fragment.Len" to UINTN.

This patch fixes a problem introduced by commit
61bb6eeb4d.
The PcdSnpCreateExitBootServicesEvent is not guaranteed to be FixedAtBuild,
so use PcdGetBool() to supports both fixed and patchable PCD.

Patch addresses Bugzilla #1974.
During ExitBootServices stage, drivers should not call any
functions known to use Memory Allocation Services. One of such
functions (as per UEFI spec) is UNDI->Shutdown().
Since UNDI drivers during ExitBootServices phase are expected
to put the adapter to such a state that it will not perform any DMA
operations, there is no need to interface UNDI by SNP driver during
that phase.
Finally, since ExitBootServices event notification function in SNP
only calls UNDI->Shutdown() and Stop() functions, there is no need
to create this event at all. Adding PCD to control creation of event
reacting to ExitBootServices() call so that systems with UNDIs relying
on SNP to call their Shutdown() and Stop() can still work.
