If +the QEMU process doesn't have permissions to use O_NOATIME (namely, it +does not own the file nor have the CAP_FOWNER capability), the open will +fail. This causes issues when from the client's point of view, it +believes it has permissions to use O_NOATIME (e.g., a process running as +root in the virtual machine). Additionally, overlayfs on Linux opens +files on the lower layer using O_NOATIME, so in this case a 9pfs mount +can't be used as a lower layer for overlayfs (cf. +https://github.com/osandov/drgn/blob/dabfe1971951701da13863dbe6d8a1d172ad9650/vmtest/onoatimehack.c +and https://github.com/NixOS/nixpkgs/issues/54509). + +Luckily, O_NOATIME is effectively a hint, and is often ignored by, e.g., +network filesystems. open(2) notes that O_NOATIME "may not be effective +on all filesystems. One example is NFS, where the server maintains the +access time."

This is +currently mitigated using a reclaim logic : the server closes the file +descriptors of idle fids, based on the assumption that it will be able +to re-open them later. This assumption doesn't hold of course if the +client requests the file to be unlinked. In this case, we loop on the +entire fid list and mark all related fids as unreclaimable (the reclaim +logic will just ignore them) and, of course, we open or re-open their +file descriptors if needed since we're about to unlink the file. + +This is the purpose of v9fs_mark_fids_unreclaim(). Since the actual +opening of a file can cause the coroutine to yield, another client +request could possibly add a new fid that we may want to mark as +non-reclaimable as well. The loop is thus restarted if the re-open +request was actually transmitted to the backend. This is achieved +by keeping a reference on the first fid (head) before traversing +the list. + +This is wrong in several ways: +- a potential clunk request from the client could tear the first + fid down and cause the reference to be stale. This leads to a + use-after-free error that can be detected with ASAN, using a + custom 9p client +- fids are added at the head of the list : restarting from the + previous head will always miss fids added by a some other + potential request + +All these problems could be avoided if fids were being added at the +end of the list. This can be achieved with a QSIMPLEQ, but this is +probably too much change for a bug fix. For now let's keep it +simple and just restart the loop from the current head. + +Fixes: CVE-2021-20181 +Buglink: https://bugs.launchpad.net/qemu/+bug/1911666 +Reported-by: Zero Day Initiative <zdi-disclosures@trendmicro.com> +Reviewed-by: Christian Schoenebeck <qemu_oss@crudebyte.com> +Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> +Message-Id: <161064025265.1838153.15185571283519390907.stgit@bahia.lan> +Signed-off-by: Greg Kurz <groug@kaod.org> + +Upstream-Status: Backport [89fbea8737e8f7b954745a1ffc4238d377055305] +CVE: CVE-2021-20181 + +Signed-off-by: Sakib Sajal <sakib.sajal@windriver.com> +--- + hw/9pfs/9p.c | 6 +++--- + 1 file changed, 3 insertions(+), 3 deletions(-) + +diff --git a/hw/9pfs/9p.c b/hw/9pfs/9p.c +index 94df440fc..6026b51a1 100644 +--- a/hw/9pfs/9p.c ++++ b/hw/9pfs/9p.c +@@ -502,9 +502,9 @@ static int coroutine_fn v9fs_mark_fids_unreclaim(V9fsPDU *pdu, V9fsPath *path) + { + int err; + V9fsState *s = pdu->s; +- V9fsFidState *fidp, head_fid; ++ V9fsFidState *fidp; + +- head_fid.next = s->fid_list; ++again: + for (fidp = s->fid_list; fidp; fidp = fidp->next) { + if (fidp->path.size != path->size) { + continue; +@@ -524,7 +524,7 @@ static int coroutine_fn v9fs_mark_fids_unreclaim(V9fsPDU *pdu, V9fsPath *path) + * switched to the worker thread + */ + if (err == 0) { +- fidp = &head_fid; ++ goto again; + } + } + } +-- +2.29.2 + diff --git a/meta/recipes-devtools/qemu/qemu/CVE-2021-20196.patch b/meta/recipes-devtools/qemu/qemu/CVE-2021-20196.patch new file mode 100644 index 0000000000..e9b815740f --- /dev/null +++ b/meta/recipes-devtools/qemu/qemu/CVE-2021-20196.patch @@ -0,0 +1,62 @@ +From 94608c59045791dfd35102bc59b792e96f2cfa30 Mon Sep 17 00:00:00 2001 +From: Vivek Kumbhar <vkumbhar@mvista.com> +Date: Tue, 29 Nov 2022 15:57:13 +0530 +Subject: [PATCH] CVE-2021-20196 + +Upstream-Status: Backport [https://gitlab.com/qemu-project/qemu/-/commit/1ab95af033a419e7a64e2d58e67dd96b20af5233] +CVE: CVE-2021-20196 +Signed-off-by: Vivek Kumbhar <vkumbhar@mvista.com> + +hw/block/fdc: Kludge missing floppy drive to fix CVE-2021-20196 + +Guest might select another drive on the bus by setting the +DRIVE_SEL bit of the DIGITAL OUTPUT REGISTER (DOR). +The current controller model doesn't expect a BlockBackend +to be NULL.
