2018-01-04MdeModulePkg/DxeNetLib: Add parameter check and ASSERT handling.Wang Fan1-14/+105
* Library API should check the input parameters before use, or ASSERT to tell it has to meet some requirements. But in DxeNetLib, not all functions follows this rule. * ASSERT shouldn't be used as error handling, add some handling code for errors. * Add some ASSERT commence in function notes.

2018-01-02MdeModulePkg/DxePrintLibPrint2Protocol: Fix incomplete print outputWang, Jian J1-2/+6
This is caused by a previous patch which tried to fix string over-read. It's found that that patch for PrintLib in MdePkg will cause premature terminating of loop used to traversing format string and cause incomplete string output. Because this library uses similar code to do the same job, it has the same issue too. So the fix is also the same.

2017-11-29MdeModulePkg/DxeCorePerformanceLib: add lock protectionHeyi Guo1-1/+66
DXE performance gauge record access functions might be reentered since we are supporting something like USB hot-plug, which is a timer event where gBS->ConnectController might be called and then PERF will be called in CoreConnectSingleController. When StartGaugeEx is being reentered, not only the gauge record might be overwritten, more serious situation will be caused if gauge data buffer reallocation procedure is interrupted, between line 180 and 187 in DxeCorePerformanceLib.c specifically. There, mMaxGaugeRecords will be doubled twice (denoted as 4X), but mGaugeData only points to a buffer of size 2X, which will probably cause the following 2X memory to be overflowed when gauge records are increased. So we add EFI lock with TPL_NOTIFY in StartGaugeEx/EndGaugeEx/GetGaugeEx to avoid memory overflow and gauge data corruption.

2017-11-13MdeModulePkg: Update IP4 stack to support point-to-point link with 31-bit mask.Fu Siyuan1-4/+10
V2 update: Directly use NetIp4IsUnicast() to check station address in IP driver. This patch is to follow RFC3021 which allows to use 31-bit mask in point-to-point link. If a 31-bit subnet mask is assigned to a point-to-point link, it leaves the <Host-number> with only 1 bit. Consequently, only two possible addresses may result: {<Network-number>, 0} and {<Network-number>, -1} These addresses have historically been associated with network and broadcast addresses (see Section 2.2). In a point-to-point link with a 31-bit subnet mask, the two addresses above MUST be interpreted as host addresses.

2017-08-01MdeModulePkg PiSmmCoreMemoryAllocLib: Fix a FreePool() assertion issueStar Zeng1-4/+28
When PiSmmCore links against PeiDxeDebugLibReportStatusCode, the code flow below will cause a FreePool() assertion issue. PiSmmCoreMemoryAllocationLibConstructor() -> SmmInitializeMemoryServices() -> DEBUG ((DEBUG_INFO, "SmmAddMemoryRegion\n")) in SmmAddMemoryRegion() -> DebugPrint() -> REPORT_STATUS_CODE_EX() -> ReportStatusCodeEx() -> AllocatePool()/FreePool(PiSmmCoreMemoryAllocLib) -> ASSERT() at Head = CR (Buffer, POOL_HEAD, Data, POOL_HEAD_SIGNATURE) in CoreFreePoolI() of DxeCore Pool.c It is because at the point of FreePool() in the code flow above, mSmmCoreMemoryAllocLibSmramRanges/mSmmCoreMemoryAllocLibSmramRangeCount are not been initialized yet, the FreePool() will be directed to gBS->FreePool(), that is wrong. This patch is to temporarily use BootServicesData to hold the SmramRanges data before calling SmmInitializeMemoryServices().
