I'll submit a v2 subseries with the first 5 patches: > MdePkg/PiFirmwareFile: express IS_SECTION2 in terms of SECTION_SIZE > MdePkg/PiFirmwareFile: fix undefined behavior in SECTION_SIZE > BaseTools/PiFirmwareFile: fix undefined behavior in SECTION_SIZE > MdePkg/PiFirmwareFile: fix undefined behavior in FFS_FILE_SIZE > OvmfPkg/Sec: fix out-of-bounds reads This is because patches 2 through 4 have to be reworked, and patches 1 and 5 make no real sense without 2-4. Regarding the rest (6-10): > OvmfPkg/QemuVideoDxe: avoid arithmetic on null pointer > OvmfPkg/AcpiPlatformDxe: suppress invalid "deref of undef pointer" > warning > OvmfPkg: suppress "Value stored to ... is never read" analyzer > warnings > OvmfPkg/AcpiPlatformDxe: catch theoretical nullptr deref in Xen code > OvmfPkg/BasePciCapLib: suppress invalid "nullptr deref" warning I've dropped patch 8 because both Jordan and I dislike it quite a bit, and it only aims to suppress invalid warnings. I can do that in RH covscan too. I've pushed the rest (6-7 and 9-10) with Ard's A-b, and also picked up Phil's R-b wherever he posted it (933f1990f583..c2f643479eb3): 1 52d229238b2d OvmfPkg/QemuVideoDxe: avoid arithmetic on null pointer 2 dc5bbf10741c OvmfPkg/AcpiPlatformDxe: suppress invalid "deref of undef pointer" warning 3 e30991740d18 OvmfPkg/AcpiPlatformDxe: catch theoretical nullptr deref in Xen code 4 c2f643479eb3 OvmfPkg/BasePciCapLib: suppress invalid "nullptr deref" warning Thanks, Laszlo -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
