Subject: [PATCH 00/12] OvmfPkg/IoMmuDxe: cleanups and fixes
Date: Wed, 2 Aug 2017 23:24:41 +0200 [thread overview]
Message-ID: <20170802212453.19221-1-lersek@redhat.com> (raw)
This series is proposed as a replacement (or a replacement "basis") for
patches #1 through #3 of Brijesh's series
[PATCH v1 0/4] OvmfPkg : IoMmuDxe: BusMasterCommonBuffer support when
SEV is active
http://mid.mail-archive.com/1501529474-20550-1-git-send-email-brijesh.singh@amd.com
Patch #4 of the same series ("OvmfPkg : QemuFwCfgLib: Map DMA buffer
with CommonBuffer when SEV is enable") is required on top of this
series; otherwise QemuFwCfgLib will break on SEV.
In the present series, patches #1 through #7 are lightweight
improvements for OvmfPkg/IoMmuDxe, concerning line width, MAP_INFO field
names, conversion specifiers for DEBUG(), coding style, error
propagation, and library class listings.
Patch #8 ("zero out pages before releasing them") fixes the "information
leak" issue pointed out in:
http://mid.mail-archive.com/e1137140-f5d5-7eb8-0162-952694b24f96@redhat.com
Patch #9 ('rework setup of "MapInfo->PlainTextAddress" in Map()') fixes
as-yet undiscussed issues, and lays the groundwork for patch #10, by
reworking the calculation of the plaintext buffer address.
Patch #10 ("implement in-place decryption/encryption for Map/Unmap")
fixes the issues around BusMasterCommonBuffer[64] operations that were
discussed in the following messages:
http://mid.mail-archive.com/4071596d-32c9-e6d9-8c93-0d43d28e9b5a@redhat.com
http://mid.mail-archive.com/e1137140-f5d5-7eb8-0162-952694b24f96@redhat.com
http://mid.mail-archive.com/84c3c5db-623e-181b-c472-7fd7ae1c1670@amd.com
http://mid.mail-archive.com/89e1553a-1630-87a5-cffd-99174a380d41@redhat.com
Patch #11 ("abort harder on memory encryption mask failures") settles
the error handling for MemEncryptSevClearPageEncMask() and
MemEncryptSevSetPageEncMask(), discussed in:
http://mid.mail-archive.com/89e1553a-1630-87a5-cffd-99174a380d41@redhat.com
Patch #12 ("Unmap(): recycle MAP_INFO after BusMasterCommonBuffer[64]")
implements the "free list" proposed in:
http://mid.mail-archive.com/e1137140-f5d5-7eb8-0162-952694b24f96@redhat.com
The series has been formatted with "--function-context", for easier
review.
