Subject: [PATCH v2 5/6] MdeModulePkg: Delete UefiPxeBcDxe in MdeModulePkg.
Date: Thu, 20 Dec 2018 09:41:09 +0800 [thread overview]
Message-ID: <20181220014110.20324-6-siyuan.fu@intel.com> (raw)
In-Reply-To: <20181220014110.20324-1-siyuan.fu@intel.com>
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1278
This patch is to delete the UefiPxeBcDxe driver in MdeModulePkg. The
driver will not be maintained and can't co-work with the dual-stack
UefiPxeBcDxe in NetworkPkg.
People should use below NetworkPkg drivers instead:
NetworkPkg/UefiPxeBcDxe/UefiPxeBcDxe.inf
Which is actively maintained with more bug fixes and new feature support.

-/**
- Used to perform TFTP and MTFTP services.
-
- This function is used to perform TFTP and MTFTP services. This includes the
- TFTP operations to get the size of a file, read a directory, read a file, and
- write a file. It also includes the MTFTP operations to get the size of a file,
- read a directory, and read a file. The type of operation is specified by Operation.
- If the callback function that is invoked during the TFTP/MTFTP operation does
- not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will
- be returned.
- For read operations, the return data will be placed in the buffer specified by
- BufferPtr. If BufferSize is too small to contain the entire downloaded file,
- then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero
- or the size of the requested file (the size of the requested file is only returned
- if the TFTP server supports TFTP options). If BufferSize is large enough for the
- read operation, then BufferSize will be set to the size of the downloaded file,
- and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services
- should use the get-file-size operations to determine the size of the downloaded
- file prior to using the read-file operations-especially when downloading large
- (greater than 64 MB) files-instead of making two calls to the read-file operation.
- Following this recommendation will save time if the file is larger than expected
- and the TFTP server does not support TFTP option extensions. Without TFTP option
- extension support, the client has to download the entire file, counting and discarding
- the received packets, to determine the file size.
- For write operations, the data to be sent is in the buffer specified by BufferPtr.
- BufferSize specifies the number of bytes to send. If the write operation completes
- successfully, then EFI_SUCCESS will be returned.
- For TFTP "get file size" operations, the size of the requested file or directory
- is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
- does not support options, the file will be downloaded into a bit bucket and the
- length of the downloaded file will be returned. For MTFTP "get file size" operations,
- if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED
- will be returned.
- This function can take up to 10 seconds to timeout and return control to the caller.
- If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
- If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
- then the TFTP sequence is stopped and EFI_ABORTED will be returned.
- The format of the data returned from a TFTP read directory operation is a null-terminated
- filename followed by a null-terminated information string, of the form
- "size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that
- the seconds field can be a decimal number), where the date and time are UTC. For
- an MTFTP read directory command, there is additionally a null-terminated multicast
- IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final
- entry is itself null-terminated, so that the final information string is terminated
- with two null octets.
-
- @param This Pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance.
- @param Operation The type of operation to perform.
- @param BufferPtr A pointer to the data buffer.
- @param Overwrite Only used on write file operations. TRUE if a file on a remote server can
- be overwritten.
- @param BufferSize For get-file-size operations, *BufferSize returns the size of the
- requested file.
- @param BlockSize The requested block size to be used during a TFTP transfer.
- @param ServerIp The TFTP / MTFTP server IP address.
- @param Filename A Null-terminated ASCII string that specifies a directory name or a file
- name.
- @param Info Pointer to the MTFTP information.
- @param DontUseBuffer Set to FALSE for normal TFTP and MTFTP read file operation.
-
- @retval EFI_SUCCESS The TFTP/MTFTP operation was completed.
- @retval EFI_NOT_STARTED The PXE Base Code Protocol is in the stopped state.
- @retval EFI_INVALID_PARAMETER One or more parameters are invalid.
- @retval EFI_DEVICE_ERROR The network device encountered an error during this operation.
- @retval EFI_BUFFER_TOO_SMALL The buffer is not large enough to complete the read operation.
- @retval EFI_ABORTED The callback function aborted the TFTP/MTFTP operation.
- @retval EFI_TIMEOUT The TFTP/MTFTP operation timed out.
- @retval EFI_ICMP_ERROR An ICMP error packet was received during the MTFTP session.
- @retval EFI_TFTP_ERROR A TFTP error packet was received during the MTFTP session.

- successfully received, then EFI_SUCCESS will be returned, and the information
- from the UDP header will be returned in DestIp, DestPort, SrcIp, and SrcPort if
- they are not NULL. Depending on the values of OpFlags and the DestIp, DestPort,
- SrcIp, and SrcPort input values, different types of UDP packet receive filtering
- will be performed. The following tables summarize these receive filter operations.

- @param OpFlags The UDP operation flags.
- @param DestIp The destination IP address.
- @param DestPort The destination UDP port number.

- @param SrcPort The source UDP port number.
- @param HeaderSize An optional field which may be set to the length of a header at
- HeaderPtr to be prefixed to the data at BufferPtr.
- @param HeaderPtr If HeaderSize is not NULL, a pointer to a header to be prefixed to the

- Updates the IP receive filters of a network device and enables software filtering.
-
- The NewFilter field is used to modify the network device's current IP receive
- filter settings and to enable a software filter. This function updates the IpFilter
- field of the EFI_PXE_BASE_CODE_MODE structure with the contents of NewIpFilter.
- The software filter is used when the USE_FILTER in OpFlags is set to UdpRead().
- The current hardware filter remains in effect no matter what the settings of OpFlags
- are, so that the meaning of ANY_DEST_IP set in OpFlags to UdpRead() is from those
- packets whose reception is enabled in hardware-physical NIC address (unicast),
- broadcast address, logical address or addresses (multicast), or all (promiscuous).
- UdpRead() does not modify the IP filter settings.
- Dhcp(), Discover(), and Mtftp() set the IP filter, and return with the IP receive
- filter list emptied and the filter set to EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP.
- If an application or driver wishes to preserve the IP receive filter settings,
- it will have to preserve the IP receive filter settings before these calls, and
- use SetIpFilter() to restore them after the calls. If incompatible filtering is
- requested (for example, PROMISCUOUS with anything else) or if the device does not
- support a requested filter setting and it cannot be accommodated in software
- (for example, PROMISCUOUS not supported), EFI_INVALID_PARAMETER will be returned.
- The IPlist field is used to enable IPs other than the StationIP. They may be
- multicast or unicast. If IPcnt is set as well as EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP,
- then both the StationIP and the IPs from the IPlist will be used.

- Parameters PacketLen and Packet specify the packet that generated the event. If these fields
- are zero and NULL respectively, then this is a status update callback. If the operation specified
- by Function is to continue, then CALLBACK_STATUS_CONTINUE should be returned. If the operation
- specified by Function should be aborted, then CALLBACK_STATUS_ABORT should be returned. Due to
- the polling nature of UEFI device drivers, a callback function should not execute for more than 5 ms.
- The SetParameters() function must be called after a Callback Protocol is installed to enable the
- use of callbacks.

- the callback is being invoked due to a transmit event.
- @param PacketLength The length, in bytes, of Packet. This field will have a value of zero if
- this is a wait for receive event.
- @param PacketPtr If Received is TRUE, a pointer to the packet that was just received;
- otherwise a pointer to the packet that is about to be transmitted.

-# Notes:
-# 1) This driver can't co-work with the UefiPxeBcDxe driver in NetworkPkg.
-# 2) This driver might have some issues that have been fixed in the UefiPxeBcDxe
-# driver in NetworkPkg.
-# 3) This driver supports fewer features than the UefiPxeBcDxe driver in NetworkPkg
-# (e.g. IPv6, MTFTP windowsize).
-# 4) UefiPxeBcDxe driver in NetworkPkg is recommended for use instead of this one even
-# though both of them can be used.
