Yunhua Feng d15d0d3d8a BaseTools: Should always define PCD TOKEN value as Zero for static PCD
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3120
FixedAtBuild, PatchableInModule and FeatureFlag PCD don't use PCD TOKEN.
Their PCD TOKEN value can always be zero.
AutoGen.h will not be changed when static PCD is added or removed.
Dynamic PCD add or remove will still cause dynamic PCD token value be
changed.

Tan, Ming d4945b1027 MdeModulePkg/Universal/StatusCodeHandler: Fix a bug about log lost
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3126

1. If use PeiDxeDebugLibReportStatusCode as DebugLib, then some logs
after ExitBootService() will be lost.
2. The root cause:
2.1 The original code will register an unregister function
of gEfiEventExitBootServicesGuid, this unregister function will call
EFI_RSC_HANDLER_PROTOCOL->Unregister and does not support log through
serial port.
2.2 And some other drivers also register call back funtions of
gEfiEventExitBootServicesGuid.
2.3 Then after the unregister function is called, other call back
functions can't out log if them use RSC as DebugLib.
3. The DxeMain will report status code EFI_SW_BS_PC_EXIT_BOOT_SERVICES
after notify all the call back functions of
gEfiEventExitBootServicesGuid.
4. Solution: the StatusCodeHandlerRuntimeDxe.c will not register an
unregister function of gEfiEventExitBootServicesGuid, but unregister it
after receive the status code of EFI_SW_BS_PC_EXIT_BOOT_SERVICES.

Sami Mujawar b23c5b9722 BaseTools: Fix crash in ECC when parsing incorrect header
The ECC tool crashes if a C file has an incorrect file header
format.

The file ArmPkg\Library\ArmMmuLib\AArch64\ArmMmuPeiLibConstructor.c
has a file header in the incorrect format. It uses # to mark the
header comments instead of enclosing the file header in /* */. This
may have been a result of an INF file header being copied to a C
file.

A separate patch fixes the C file but ECC tool should
not crash if a file with an incorrect header is found.

Therefore, update the ECC tool to prevent it from crashing if an
incorrect file header is found. With this change the ECC tool will
report the incorrect header issue without crashing.

Laszlo Ersek c3f76ef89d OvmfPkg/VirtioFsDxe: add helper for composing rename/move destination path
The EFI_FILE_PROTOCOL.SetInfo() member is somewhat under-specified; one of
its modes of operation is renaming/moving the file.

In order to create the destination pathname in canonical format, 2*2=4
cases have to be considered. For the sake of discussion, assume the
current canonical pathname of a VIRTIO_FS_FILE is "/home/user/f1.txt".
Then, consider the following rename/move requests from
EFI_FILE_PROTOCOL.SetInfo():

  Destination requested  Destination  Move into   Destination in
  by SetInfo()           relative?    directory?  canonical format
  ---------------------  -----------  ----------  -----------------------
  L"\\dir\\f2.txt"       no           no          "/dir/f2.txt"
  L"\\dir\\"             no           yes         "/dir/f1.txt"
  L"dir\\f2.txt"         yes          no          "/home/user/dir/f2.txt"
  L"dir\\"               yes          yes         "/home/user/dir/f1.txt"

Add the VirtioFsComposeRenameDestination() function, for composing the
last column from the current canonical pathname and the SetInfo() input.

The function works on the following principles:

- The prefix of the destination path is "/", if the SetInfo() rename
  request is absolute.

  Otherwise, the dest prefix is the "current directory" (the most specific
  parent directory) of the original pathname (in the above example,
  "/home/user").

- The suffix of the destination path is precisely the SetInfo() request
  string, if the "move into directory" convenience format -- the trailing
  backslash -- is not used. (In the above example, L"\\dir\\f2.txt" and
  L"dir\\f2.txt".)

  Otherwise, the suffix is the SetInfo() request, plus the original
  basename (in the above example, L"\\dir\\f1.txt" and L"dir\\f1.txt").

- The complete destination is created by fusing the dest prefix and the
  dest suffix, using the VirtioFsAppendPath() function.

Laszlo Ersek b845de89d0 OvmfPkg/VirtioFsDxe: add EFI_FILE_INFO cache fields to VIRTIO_FS_FILE
For reading through a directory stream with tolerable performance, we'll
have to call FUSE_READDIRPLUS each time with such a buffer that can
deliver a good number of variable size records
(VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE elements). Every time we'll do that,
we'll turn the whole bunch into an array of EFI_FILE_INFOs immediately.
EFI_FILE_PROTOCOL.Read() invocations (on directories) will be served from
this EFI_FILE_INFO cache.

Add the fields for the EFI_FILE_INFO cache to VIRTIO_FS_FILE:
- initialize them in Open() and OpenVolume(),
- release the cache in Close() and Delete(),
- also release the cache when the directory is rewound, in SetPosition().

Laszlo Ersek d98d7e3005 OvmfPkg/VirtioFsDxe: add a shared wrapper for FUSE_READ / FUSE_READDIRPLUS
Add the VirtioFsFuseReadFileOrDir() function, for sending the FUSE_READ or
FUSE_READDIRPLUS command to the Virtio Filesystem device.

Parsing the structured FUSE_READDIRPLUS output is complex, and cannot be
integrated into the wrapper function. Given that fact, FUSE_READ and
FUSE_READDIRPLUS turn out to need identical low-level handling, except for
the opcode. Hence the shared wrapper function.

(It's prudent to verify whether the FUSE server supports FUSE_READDIRPLUS,
so update the session init code accordingly.)

This is the first FUSE request wrapper function that deals with a variable
size tail buffer.

necessary lib class resolution. We need not modify any ArmVirtPkg DSC
files: see commit af5fed90bf ("ArmPlatformPkg,ArmVirtPkg: delete

Laszlo Ersek 9307d7c7a4 OvmfPkg/VirtioFsDxe: add helper for appending and sanitizing paths
EFI_FILE_PROTOCOL.Open() -- for opening files -- and
EFI_FILE_PROTOCOL.SetInfo() --  for renaming files -- will require us to
append a relative UEFI pathname to an absolute base pathname. In turn,
components of the resultant pathnames will have to be sent to virtiofsd,
which does not consume UEFI-style pathnames.

We're going to maintain the base pathnames in canonical POSIX format:
- absolute (starts with "/"),
- dot (.) and dot-dot (..) components resolved/removed,
- uses forward slashes,
- sequences of slashes collapsed,
- printable ASCII character set,
- CHAR8 encoding,
- no trailing slash except for the root directory itself,
- length at most VIRTIO_FS_MAX_PATHNAME_LENGTH.

Add a helper function that can append a UEFI pathname to such a base
pathname, and produce the result in conformance with the same invariants.

Laszlo Ersek 28092a3938 OvmfPkg/VirtioFsDxe: flush, sync, release and forget in Close() / Delete()
The two member functions that free the EFI_FILE_PROTOCOL object are
Close() and Delete(). Before we create VIRTIO_FS_FILE objects with
EFI_FILE_PROTOCOL.Open() later in this patch series, extend each of these
"destructor" functions to get rid of the FuseHandle and NodeId resources
properly -- in a way that matches each function's own purpose.

For the time being, VirtioFsSimpleFileDelete() only gets a reminder about
its core task (namely, removing the file), as the needed machinery will
become only later. But we can already outline the "task list", and deal
with the FuseHandle and NodeId resources. The "task list" of
VirtioFsSimpleFileDelete() is different from that of
VirtioFsSimpleFileClose(), thus both destructors diverge at this point.
