2015-10-16MdeModulePkg: FaultTolerantWriteDxe: mellow DEBUGs about workspace reinitLaszlo Ersek
The IsValidWorkSpace() function checks if the working block header of the workspace is valid. A mismatch detected by this function is not necessarily an error; it can happen with an as-yet unwritten flash chip, which is e.g. common and normal when a new ArmVirtQemu virtual machine is booted. Therefore downgrade the message emitted by IsValidWorkSpace() from EFI_D_ERROR to EFI_D_INFO, and change the wording from "error" to "mismatch". The only caller of IsValidWorkSpace(), InitFtwProtocol(), handles all of the following cases: (1) IsValidWorkSpace() succeeds for the working block -- this is normal operation, (2) IsValidWorkSpace() fails for the working block, but succeeds for the spare block -- InitFtwProtocol() then restores the working block from the spare block, (3) IsValidWorkSpace() fails for both the working and spare blocks -- InitFtwProtocol() reinitializes the full workspace. In cases (2) and (3), InitFtwProtocol() logs additional messages about the branch taken. Their current level is EFI_D_ERROR, but the messages are arguably informative, not necessarily error reports. Downgrade these messages from EFI_D_ERROR to EFI_D_INFO, so that they don't clutter the debug output when the PcdDebugPrintErrorLevel mask only enables EFI_D_ERROR (i.e., in a "silent" build). These messages have annoyed / confused users; see for example: - https://bugzilla.redhat.com/show_bug.cgi?id=1270279 Cc: Star Zeng <star.zeng@intel.com> Cc: Liming Gao <liming.gao@intel.com> Cc: Drew Jones <drjones@redhat.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Star Zeng <star.zeng@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@18619 6f19259b-4bc3-4df7-8a09-765794883524

When looping through all PCI functions, code should not look for functions 1-7 if function 0 is not present or if function 0 indicates the device is not multifunction. Prior to this fix the code would use stale data in a buffer to determine if a device is multifunction even if function 0 is not present. This fixes a code bug and provides very small performance improvements. PCI 2.3 Specification states: They [multifunction devices] are also required to always implement function 0 in the device.

2015-09-30MdeModulePkg Ip4Dxe: Ip4Config2 to request DHCP Option6 DNS server IPSamer El-Haj-Mahmoud
Ip4Config2 protocol implementation must request for DNS server info when the policy is set to DHCP. And when a DHCP server responds to it with a list of DNS server addresses, it must parse it and set it for the instance. Without this, nobody can do a Ip4Config->GetData for DNS server IPs before calling Dns->Configure(). This will mean a DHCP is initiated when calling Dns->Configure(), thus causing serious performance issues. This patch attempts to address this issue.

In a CloseEvent, an UnregisterProtocolNotify is done unconditionally. There is a penalty associated with searching the protocol database on every CloseEvent and impacts performance, especially during Network IO. Unregister needs to be done only if the Event is for a RegisterProtocolNotify. So extend the ExFlag in IEVENT to a UINT8 and define new flags that can be set to indicate if the Event is part of a group, or registered on a protocol notify. Then in CloseEvent, call UnregisterProtocolNotify only if the register protocol notify flag is set.

2015-09-15MdeModulePkg PiDxeS3BootScriptLib: Remove a hidden assumption.Star Zeng
What to do: 1. Remove a hidden assumption "No SMM driver writes BootScript between SmmReadyToLock and S3SleepEntryCallback". 1.1. Use SmmExitBootServices and SmmLegacyBoot notification to record AtRuntime flag. 1.2. Use mBootScriptDataBootTimeGuid LockBox to save boot time boot script data to handle potential INSERT boot script at runtime in SMM. 2. Do not depend on OS to help restore ACPINvs data and use EfiReservedMemoryType instead of EfiACPIMemoryNVS. 2.1. Use mBootScriptSmmPrivateDataGuid LockBox to save boot script SMM private data with BackFromS3 = TRUE at runtime. S3 resume will help restore it to tell the Library the system is back from S3. Why to do: 1. The hidden assumption "No SMM driver writes BootScript between SmmReadyToLock and S3SleepEntryCallback" will cause confusion to the library's consumer and block the usage of "SMM driver writes BootScript after SmmReadyToLock". So Remove the assumption. 2. In original code, there might be a corner case that malicious code patch ACPINvs boot TableLength field same as SMM boot script. So that it can skip the table restore. The impact is that BootScript in SMM may be overridden by malicious code. -------------------- CopyMem ((VOID*)&TableHeader, (VOID*)mS3BootScriptTablePtr->TableBase, sizeof(EFI_BOOT_SCRIPT_TABLE_HEADER)); if (mS3BootScriptTablePtr->TableLength + sizeof(EFI_BOOT_SCRIPT_TERMINATE) != TableHeader.TableLength) { // TableLength is in NVS ...... // // NOTE: We should NOT use TableHeader.TableLength, because it is already updated to be whole length. // mS3BootScriptTablePtr->TableLength = (UINT32)(mLockBoxLength - sizeof(EFI_BOOT_SCRIPT_TERMINATE)); ? This line can be skipped. -------------------- So use EfiReservedMemoryType instead of EfiACPIMemoryNVS as the code has been updated to not depend on OS to help restore ACPINvs data.

2015-09-15MdeModulePkg: Change the algorithm in SNP to use the first found BAR index.Fu Siyuan
The driver binding start function in SNP.c goes through all the BARs and get the last BAR index for use. Theoretically it should work with all valid BARs, but we got reports some device did always use the first valid BAR, so we change the logic in SNP to use the first found BAR index instead of the last one.

2015-09-10MdeModulePkg: ScsiDiskDxe: adapt SectorCount when shortening transfersLaszlo Ersek
The specification of the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() function documents the EFI_BAD_BUFFER_SIZE return status, and the EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN host adapter status. These allow an EFI_EXT_SCSI_PASS_THRU_PROTOCOL implementation to request higher layers in the stack (in this instance, UefiScsiLib and ScsiDiskDxe) to break up the transfer into smaller pieces. These conditions percolate up the stack correctly: the retry loops in ScsiDiskDxe's ScsiDiskReadSectors() and ScsiDiskWriteSectors() functions correctly and transparently update the transfer size (ByteCount), accommodating any shortening requested by lower levels of the stack. After the loop -- if the request ultimately succeeds -- SectorCount is even recalculated from the final ByteCount, to see how many sectors the outer loop should advance. However, the inner (ie. retry) loops both have the same error: when the underlying protocols request the transfer to be shortened, the decrease in transfer size (ie. ByteCount) should immediately be reflected in SectorCount. Otherwise the sector count encoded in the CDB will exceed the transfer size, which is a permanent error. This issue has been witnessed while booting en_windows_8.1_pro_n_vl_with_update_x86_dvd_6051127.iso on the 32-bit build of OVMF, from a virtio-scsi CD-ROM: (1) "cdboot.efi" correctly requested (from far atop) a long read: Timeout=940000000 CdbLength=10 DataDir=Read InTransferLength=134215680 OutTransferLength=0 SenseDataLength=108 Cdb: 28 00 00 00 25 DD 00 FF FF 00 ^ ^^^^^^^^^^^ ^^^^^ | | | | | number of 2KB sectors to read, | | corresponding to 2048 * 65535 = 134215680 bytes | | (see InTransferLength above) | | | LBA to read from | READ (10) (2) In turn, the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() function provided by "OvmfPkg/VirtioScsiDxe/VirtioScsi.c" asked for the request to be shortened: InTransferLength=16776704 OutTransferLength=16776704 SenseDataLength=0 HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN TargetStatus=0 Status=EFI_BAD_BUFFER_SIZE (3) Then ScsiDiskReadSectors() in "MdeModulePkg/Bus/Scsi/ScsiDiskDxe/ScsiDisk.c" retried the request with correctly shortened transfer length, but incorrectly unchanged sector count: Timeout=940000000 CdbLength=10 DataDir=Read InTransferLength=16776704 <--- updated as requested OutTransferLength=0 SenseDataLength=108 Cdb: 28 00 00 00 25 DD 00 FF FF 00 ^ ^^^^^^^^^^^ ^^^^^ | | | | | not changed! | | | LBA to read from | READ (10) (4) Since 65535 sectors of 2KB each wouldn't fit in a buffer of approx. 16MB, QEMU's virtio-scsi controller unconditionally rejected this request with VIRTIO_SCSI_S_OVERRUN, which VirtioScsiDxe then mapped to: InTransferLength=16776704 OutTransferLength=0 SenseDataLength=0 HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN TargetStatus=0 Status=EFI_DEVICE_ERROR (5) After two more tries of the same, ScsiDiskDxe passed up the error, which ultimately caused "cdboot.efi" to BSOD. Many thanks to Larry Cleeton from Microsoft for helping debug "cdboot.efi".

Instead, register a callback in the drivers entry points on the IpSec protocol installation, and process only if the protocol is installed. This speeds up the network stacks when IpSec is not installed since there is a penalty associated with searching the entire handle database on each packet processing.
