This mitigation gets automatically enabled when the above one "IBPB on

It gets automatically enabled on machines which have the

VMSCAPE
|
||||
=======
|
||||
|
||||
VMSCAPE is a vulnerability that may allow a guest to influence the branch
|
||||
prediction in host userspace. It particularly affects hypervisors like QEMU.
|
||||
|
||||
Even if a hypervisor may not have any sensitive data like disk encryption keys,
|
||||
guest-userspace may be able to attack the guest-kernel using the hypervisor as
|
||||
a confused deputy.
|
||||
|
||||
Affected processors
|
||||
-------------------
|
||||
|
||||
The following CPU families are affected by VMSCAPE:
|
||||
|
||||
**Intel processors:**
|
||||
- Skylake generation (Parts without Enhanced-IBRS)
|
||||
- Cascade Lake generation - (Parts affected by ITS guest/host separation)
|
||||
- Alder Lake and newer (Parts affected by BHI)
|
||||
|
||||
Note that, BHI affected parts that use BHB clearing software mitigation e.g.
|
||||
Icelake are not vulnerable to VMSCAPE.
|
||||
|
||||
**AMD processors:**
|
||||
- Zen series (families 0x17, 0x19, 0x1a)
|
||||
|
||||
** Hygon processors:**
|
||||
- Family 0x18
|
||||
|
||||
Mitigation
|
||||
----------
|
||||
|
||||
Conditional IBPB
|
||||
----------------
|
||||
|
||||
Kernel tracks when a CPU has run a potentially malicious guest and issues an
|
||||
IBPB before the first exit to userspace after VM-exit. If userspace did not run
|
||||
between VM-exit and the next VM-entry, no IBPB is issued.
|
||||
|
||||
Note that the existing userspace mitigation against Spectre-v2 is effective in
|
||||
protecting the userspace. They are insufficient to protect the userspace VMMs
|
||||
from a malicious guest. This is because Spectre-v2 mitigations are applied at
|
||||
context switch time, while the userspace VMM can run after a VM-exit without a
|
||||
context switch.
|
||||
|
||||
Vulnerability enumeration and mitigation is not applied inside a guest. This is
|
||||
because nested hypervisors should already be deploying IBPB to isolate
|
||||
themselves from nested guests.
|
||||
|
||||
SMT considerations
|
||||
------------------
|
||||
|
||||
When Simultaneous Multi-Threading (SMT) is enabled, hypervisors can be
|
||||
vulnerable to cross-thread attacks. For complete protection against VMSCAPE
|
||||
attacks in SMT environments, STIBP should be enabled.
|
||||
|
||||
The kernel will issue a warning if SMT is enabled without adequate STIBP
|
||||
protection. Warning is not issued when:
|
||||
|
||||
- SMT is disabled
|
||||
- STIBP is enabled system-wide
|
||||
- Intel eIBRS is enabled (which implies STIBP protection)
|
||||
|
||||
System information and options
|
||||
------------------------------
|
||||
|
||||
The sysfs file showing VMSCAPE mitigation status is:
|
||||
|
||||
/sys/devices/system/cpu/vulnerabilities/vmscape
|
||||
|
||||
The possible values in this file are:
|
||||
|
||||
* 'Not affected':
|
||||
|
||||
The processor is not vulnerable to VMSCAPE attacks.
|
||||
|
||||
* 'Vulnerable':
|
||||
|
||||
The processor is vulnerable and no mitigation has been applied.
|
||||
|
||||
* 'Mitigation: IBPB before exit to userspace':
|
||||
|
||||
Conditional IBPB mitigation is enabled. The kernel tracks when a CPU has
|
||||
run a potentially malicious guest and issues an IBPB before the first
|
||||
exit to userspace after VM-exit.
|
||||
|
||||
* 'Mitigation: IBPB on VMEXIT':
|
||||
|
||||
IBPB is issued on every VM-exit. This occurs when other mitigations like
|
||||
RETBLEED or SRSO are already issuing IBPB on VM-exit.
|
||||
|
||||
Mitigation control on the kernel command line
|
||||
----------------------------------------------
|
||||
|
||||
The mitigation can be controlled via the ``vmscape=`` command line parameter:
|
||||
|
||||
* ``vmscape=off``:
|
||||
|
||||
Disable the VMSCAPE mitigation.
|
||||
|
||||
* ``vmscape=ibpb``:
|
||||
|
||||
Enable conditional IBPB mitigation (default when CONFIG_MITIGATION_VMSCAPE=y).
|
||||
|
||||
* ``vmscape=force``:
|
||||
|
||||
Force vulnerability detection and mitigation even on processors that are
|
||||
not known to be affected.

Inline encryption support
|
||||
=========================
|
||||
|
||||
By default, fscrypt uses the kernel crypto API for all cryptographic
|
||||
operations (other than HKDF, which fscrypt partially implements
|
||||
itself). The kernel crypto API supports hardware crypto accelerators,
|
||||
but only ones that work in the traditional way where all inputs and
|
||||
outputs (e.g. plaintexts and ciphertexts) are in memory. fscrypt can
|
||||
take advantage of such hardware, but the traditional acceleration
|
||||
model isn't particularly efficient and fscrypt hasn't been optimized
|
||||
for it.
|
||||
|
||||
Instead, many newer systems (especially mobile SoCs) have *inline
|
||||
encryption hardware* that can encrypt/decrypt data while it is on its
|
||||
way to/from the storage device. Linux supports inline encryption
|
||||
through a set of extensions to the block layer called *blk-crypto*.
|
||||
blk-crypto allows filesystems to attach encryption contexts to bios
|
||||
(I/O requests) to specify how the data will be encrypted or decrypted
|
||||
in-line. For more information about blk-crypto, see

===============================

LOCALIO provides the nfs_uuid_t object and associated interfaces to

allow proper network namespace (net-ns) and NFSD object refcounting:
|
||||
allow proper network namespace (net-ns) and NFSD object refcounting.
|
||||
|
||||
We don't want to keep a long-term counted reference on each NFSD's
|
||||
net-ns in the client because that prevents a server container from
|
||||
completely shutting down.
|
||||
|
||||
So we avoid taking a reference at all and rely on the per-cpu
|
||||
reference to the server (detailed below) being sufficient to keep
|
||||
the net-ns active. This involves allowing the NFSD's net-ns exit
|
||||
code to iterate all active clients and clear their ->net pointers
|
||||
(which are needed to find the per-cpu-refcount for the nfsd_serv).
|
||||
|
||||
Details:
|
||||
|
||||
- Embed nfs_uuid_t in nfs_client. nfs_uuid_t provides a list_head
|
||||
that can be used to find the client. It does add the 16-byte
|
||||
uuid_t to nfs_client so it is bigger than needed (given that
|
||||
uuid_t is only used during the initial NFS client and server
|
||||
LOCALIO handshake to determine if they are local to each other).
|
||||
If that is really a problem we can find a fix.
|
||||
|
||||
- When the nfs server confirms that the uuid_t is local, it moves
|
||||
the nfs_uuid_t onto a per-net-ns list in NFSD's nfsd_net.
|
||||
|
||||
- When each server's net-ns is shutting down - in a "pre_exit"
|
||||
handler, all these nfs_uuid_t have their ->net cleared. There is
|
||||
an rcu_synchronize() call between pre_exit() handlers and exit()
|
||||
handlers so any caller that sees nfs_uuid_t ->net as not NULL can
|
||||
safely manage the per-cpu-refcount for nfsd_serv.
|
||||
|
||||
- The client's nfs_uuid_t is passed to nfsd_open_local_fh() so it
|
||||
can safely dereference ->net in a private rcu_read_lock() section
|
||||
to allow safe access to the associated nfsd_net and nfsd_serv.
|
||||
|
||||
So LOCALIO required the introduction and use of NFSD's percpu_ref to
|
||||
interlock nfsd_destroy_serv() and nfsd_open_local_fh(), to ensure each
|
||||
nn->nfsd_serv is not destroyed while in use by nfsd_open_local_fh(), and
|
||||
LOCALIO required the introduction and use of NFSD's percpu nfsd_net_ref
|
||||
to interlock nfsd_shutdown_net() and nfsd_open_local_fh(), to ensure
|
||||
each net-ns is not destroyed while in use by nfsd_open_local_fh(), and
|
||||
warrants a more detailed explanation:
|
||||
|
||||
nfsd_open_local_fh() uses nfsd_serv_try_get() before opening its
|
||||
nfsd_open_local_fh() uses nfsd_net_try_get() before opening its
|
||||
nfsd_file handle and then the caller (NFS client) must drop the
|
||||
reference for the nfsd_file and associated nn->nfsd_serv using
|
||||
nfs_file_put_local() once it has completed its IO.
|
||||
reference for the nfsd_file and associated net-ns using
|
||||
nfsd_file_put_local() once it has completed its IO.
|
||||
|
||||
This interlock working relies heavily on nfsd_open_local_fh() being
|
||||
afforded the ability to safely deal with the possibility that the
|
||||
NFSD's net-ns (and nfsd_net by association) may have been destroyed
|
||||
by nfsd_destroy_serv() via nfsd_shutdown_net() -- which is only
|
||||
possible given the nfs_uuid_t ->net pointer managemenet detailed
|
||||
above.
|
||||
by nfsd_destroy_serv() via nfsd_shutdown_net().
|
||||
|
||||
All told, this elaborate interlock of the NFS client and server has been
|
||||
verified to fix an easy to hit crash that would occur if an NFSD
|
||||
instance running in a container, with a LOCALIO client mounted, is
|
||||
shutdown. Upon restart of the container and associated NFSD the client
|
||||
would go on to crash due to NULL pointer dereference that occurred due
|
||||
to the LOCALIO client's attempting to nfsd_open_local_fh(), using
|
||||
nn->nfsd_serv, without having a proper reference on nn->nfsd_serv.

NFS Client issues IO instead of Server

@ -306,6 +272,22 @@ is issuing IO to the underlying local filesystem that it is sharing with
|
|||
the NFS server. See: fs/nfs/localio.c:nfs_local_doio() and
|
||||
fs/nfs/localio.c:nfs_local_commit().
|
||||
|
||||
With normal NFS that makes use of RPC to issue IO to the server, if an
|
||||
application uses O_DIRECT the NFS client will bypass the pagecache but
|
||||
the NFS server will not. The NFS server's use of buffered IO affords
|
||||
applications to be less precise with their alignment when issuing IO to
|
||||
the NFS client. But if all applications properly align their IO, LOCALIO
|
||||
can be configured to use end-to-end O_DIRECT semantics from the NFS
|
||||
client to the underlying local filesystem, that it is sharing with
|
||||
the NFS server, by setting the 'localio_O_DIRECT_semantics' nfs module
|

parameter to Y, e.g.:
|
||||
|
||||
echo Y > /sys/module/nfs/parameters/localio_O_DIRECT_semantics
|
||||
|
||||
Once enabled, it will cause LOCALIO to use end-to-end O_DIRECT semantics
|

(but again, this may cause IO to fail if applications do not properly
|

align their IO).
