2016-02-18MdeModulePkg: Define a general function to create DNS QNameJiaxin Wu
This patch is used to define a general function to create DNS QName. QName is a domain name represented as a sequence of labels, where each label consists of a length octet followed by that number of octets. The domain name terminates with the zero length octet for the null label of the root.

2016-02-18BaseTools: LzmaCompress: fix gcc-6 warning "misleading-indentation"Laszlo Ersek
The way the first use of the "_maxMode" variable is commented out (i.e., together with the enclosing "if" statement) in GetOptimum() triggers the "misleading-indentation" warning that is new in gcc-6.0, for the block of code that originally depended on the "if" statement. Gcc believes (mistakenly) that the programmer believes (mistakenly) that the block depends on (repIndex == 0) higher up. Restore the if statement, with a controlling expression that comprises the constant 1 and "_maxMode" commented out.

It displays the symbol name, the symbol address, and a message that describes both possibilities (bad symbol definition or unsupported symbol type). It also provides two examples of unsupported symbol types. Furthermore, this patch revises the conditional for detecting bad symbol definitions to eliminate a redundant test (a Sym->st_shndx value of SHN_ABS should certainly be greater than mEhdr->e_shnum) and to change another test from 'Sym->st_shndx > mEhdr->e_shnum' to 'Sym->st_shndx >= mEhdr->e_shnum' for consistency with the test in GetShdrByIndex.

2016-02-15OvmfPkg: simplify VARIABLE_STORE_HEADER generationLaszlo Ersek
Before the merger of the authenticated and non-authenticated variable drivers (commit fa0737a839d0), we had to match the varstore header GUID in "OvmfPkg/VarStore.fdf.inc" to SECURE_BOOT_ENABLE, because the opposite GUID would cause either driver to fail an assertion. The header structures for individual variables residing in the varstore were different (VARIABLE_HEADER vs. AUTHENTICATED_VARIABLE_HEADER), and each driver could only handle its own, so this GUID enforcement was necessary. Since the unification of the variable driver however, it treats (a) variable store format, and (b) AuthVariableLib instance as independent characteristics; it can always manipulate variable stores with both header types. All variations boot now; the difference is whether authenticated variables, and special variables computed from them (like SecureBoot) are supported at runtime: variable store non-auth auth and SB header GUID AuthVariableLib variables variables -- --------------------- ------------------- -> --------- ----------- 1 Variable SecurityPkg/... supported unsupported 2 Variable AuthVariableLibNull supported unsupported 3 AuthenticatedVariable SecurityPkg/... supported supported 4 AuthenticatedVariable AuthVariableLibNull supported unsupported At the moment, SECURE_BOOT_ENABLE selects between cases #2 (FALSE) and #3 (TRUE). That is, it controls both the varstore header GUID in "OvmfPkg/VarStore.fdf.inc", and the AuthVariableLib resolution in the DSC files. Exploiting the unified driver's flexibility, we can simplify "OvmfPkg/VarStore.fdf.inc" by picking the AuthenticatedVariable GUID as a constant, and letting SECURE_BOOT_ENABLE control only the AuthVariableLib resolution. This amounts to SECURE_BOOT_ENABLE choosing between cases #3 (TRUE) and #4 (FALSE), with identical results as before.

2016-02-10EmbeddedPkg/Lan9118Dxe: add PCD for negotiation timeoutRyan Harkin
Add a PCD for the link negotiation timeout so the platform can over-ride the default value. The code previously did 2000 iterations of the loop with a 2us stall, so the code has been changed subtly to set the number of iterations equal to the PCD value divided by the stall time. Since the stall time has not changed, the default PCD value is set at 4000 so the original behaviour is not changed. The problems were discovered when the ARM Juno Development Platform used the "EFI Network" option with then LAN9118 driver. It fails to boot the first time and so the board drops back to Shell again: Warning: LAN9118 Driver in stopped state Link timeout in auto-negotiation. Lan9118: Auto Negociation not supported.

2016-02-10EmbeddedPkg/Lan9118Dxe: use MemoryFenceRyan Harkin
When reviewing my LAN9118 driver PCD patch [1], Ard Biesheuvel noted that most calls to gBS->Stall() in this driver seem to be used to prevent timing issues between the device updating data and the host reading the values. And that replacing most of these calls with a MemoryFence() would be more robust. The only exceptions are the stalls that are enclosed inside retry loops: - in the AutoNegotiate() function. This stall is waiting for the link to negotiate, which may require stalling until it is ready. - in the Lan9118Initialize() function. These two stalls are waiting for devices and time out after a number of retries. - in the SoftReset() function. This stall is inside a loop where the comment states: "If time taken exceeds 100us, then there was an error condition" In these instances, I kept the stall, but also added a MemoryFence().
