#     Merge tag 'xsa-5.19-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
#     
#     Pull xen security fixes from Juergen Gross:
#     
#      - XSA-403 (4 patches for blkfront and netfront drivers):
#     
#        Linux Block and Network PV device frontends don't zero memory regions
#        before sharing them with the backend (CVE-2022-26365,
#        CVE-2022-33740). 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.
#
