Additionally the granularity of the grant table # doesn't allow sharing less than a 4K page, leading to unrelated data # residing in the same 4K page as data shared with a backend being # accessible by such backend (CVE-2022-33741, CVE-2022-33742). # # - XSA-405 (1 patch for netfront driver, only 5.10 and newer): # # While adding logic to support XDP (eXpress Data Path), a code label # was moved in a way allowing for SKBs having references (pointers) # retained for further processing to nevertheless be freed. # # - XSA-406 (1 patch for Arm specific dom0 code): # # When mapping pages of guests on Arm, dom0 is using an rbtree to keep # track of the foreign mappings. # # Updating of that rbtree is not always done completely with the # related lock held, resulting in a small race window, which can be # used by unprivileged guests via PV devices to cause inconsistencies # of the rbtree. These inconsistencies can lead to Denial of Service # (DoS) of dom0, e.g. by causing crashes or the inability to perform # further mappings of other guests' memory pages. # # * tag 'xsa-5.19-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: # xen/arm: Fix race in RB-tree based P2M accounting # xen-netfront: restore __skb_queue_tail() positioning in xennet_get_responses() # xen/blkfront: force data bouncing when backend is untrusted # xen/netfront: force data bouncing when backend is untrusted # xen/netfront: fix leaking data in shared pages # xen/blkfront: fix leaking data in shared pages # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 e35e5b6f695d241ffb1d223207da58a1fbcdff4b # < make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # < make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:12581:warning: override: reassigning to symbol GCC_PLUGIN_SANCOV .config:12586:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12588:warning: override: reassigning to symbol UML_NET_SLIP .config:12591:warning: override: reassigning to symbol UML_NET_MCAST .config:12593:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/drivers/nvdimm/pmem.c:48:20: error: conflicting types for 'to_phys' static phys_addr_t to_phys(struct pmem_device *pmem, phys_addr_t offset) ^ In file included from /kisskb/src/arch/um/include/asm/page.h:98:0, from /kisskb/src/arch/um/include/asm/thread_info.h:15, from /kisskb/src/include/linux/thread_info.h:60, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/um/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/include/linux/spinlock.h:55, from /kisskb/src/include/linux/wait.h:9, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/include/linux/highmem.h:5, from /kisskb/src/include/linux/bvec.h:10, from /kisskb/src/include/linux/blk_types.h:10, from /kisskb/src/include/linux/blkdev.h:9, from /kisskb/src/drivers/nvdimm/pmem.c:10: /kisskb/src/arch/um/include/shared/mem.h:12:29: note: previous definition of 'to_phys' was here static inline unsigned long to_phys(void *virt) ^ In file included from /kisskb/src/arch/um/include/asm/page.h:114:0, from /kisskb/src/arch/um/include/asm/thread_info.h:15, from /kisskb/src/include/linux/thread_info.h:60, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/um/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/include/linux/spinlock.h:55, from /kisskb/src/include/linux/wait.h:9, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/include/linux/highmem.h:5, from /kisskb/src/include/linux/bvec.h:10, from /kisskb/src/include/linux/blk_types.h:10, from /kisskb/src/include/linux/blkdev.h:9, from /kisskb/src/drivers/nvdimm/pmem.c:10: /kisskb/src/drivers/nvdimm/pmem.c: In function 'pmem_dax_zero_page_range': /kisskb/src/arch/um/include/asm/page.h:105:20: error: too few arguments to function 'to_phys' #define __pa(virt) to_phys((void *) (unsigned long) (virt)) ^ /kisskb/src/include/asm-generic/memory_model.h:18:41: note: in definition of macro '__pfn_to_page' #define __pfn_to_page(pfn) (mem_map + ((pfn) -
