- Updating to Sphinx v3.1.2 in Factory is exposing an issue in qemu doc sources. Fix it docs-fix-trace-docs-build-with-sphinx-3..patch - Fix DoS possibility in ati-vga emulation (CVE-2020-13800 bsc#1172495) ati-vga-check-mm_index-before-recursive-.patch - Fix DoS possibility in Network Block Device (nbd) support infrastructure (CVE-2020-10761 bsc#1172710) nbd-server-Avoid-long-error-message-asse.patch - Fix null pointer dereference possibility (DoS) in MegaRAID SAS 8708EM2 emulation (CVE-2020-13659 bsc#1172386) exec-set-map-length-to-zero-when-returni.patch - Fix OOB access possibility in MegaRAID SAS 8708EM2 emulation (CVE-2020-13362 bsc#1172383) megasas-use-unsigned-type-for-reply_queu.patch - Fix legacy IGD passthrough hw-vfio-pci-quirks-Fix-broken-legacy-IGD.patch - The latest gcc10 available in Factory has the fix for the issue this patch was created to avoid, so drop it build-Work-around-gcc10-bug-by-not-using.patch - Switch to upstream versions of some patches we carry add-enum-cast-to-avoid-gcc10-warning.patch -> golan-Add-explicit-type-casts-for-nodnic.patch Be-explicit-about-fcommon-compiler-direc.patch -> build-Be-explicit-about-fcommon-compiler.patch Do-not-apply-WORKAROUND_CFLAGS-for-host-.patch -> build-Do-not-apply-WORKAROUND_CFLAGS-for.patch Fix-s-directive-argument-is-null-error.patch -> build-Fix-s-directive-argument-is-null-e.patch Workaround-compilation-error-with-gcc-9..patch -> build-Workaround-compilation-error-with-.patch work-around-gcc10-problem-with-zero-leng.patch -> intel-Avoid-spurious-compiler-warning-on.patch - Fix vgabios issue for cirrus graphics emulation, which effectively downgraded it to standard VGA behavior vga-fix-cirrus-bios.patch - Fix OOB access possibility in ES1370 audio device emulation (CVE-2020-13361 bsc#1172384) es1370-check-total-frame-count-against-c.patch OBS-URL: https://build.opensuse.org/request/show/822154 OBS-URL: https://build.opensuse.org/package/show/Virtualization/qemu?expand=0&rev=553

Subject: s390x: protvirt: Move diag 308 data over SIDA
|
|
|
|
Git-commit: 258da1c7736d3aa4604ceea6cce00995c6f30058
|
|
References: bsc#1167075
|
|
|
|
For protected guests the IPIB is written/read to/from the SIDA, so we
|
|
need those accesses to go through s390_cpu_pv_mem_read/write().
