This interface requires ACPI and firmware support. (see the -+`PPI specification`_) -+ -+PPI enables a system administrator (root) to request a modification to -+the TPM upon reboot. The PPI specification defines the operation -+requests and the actions the firmware has to take. The system -+administrator passes the operation request number to the firmware -+through an ACPI interface which writes this number to a memory -+location that the firmware knows. Upon reboot, the firmware finds the -+number and sends commands to the TPM. The firmware writes the TPM -+result code and the operation request number to a memory location that -+ACPI can read from and pass the result on to the administrator. -+ -+The PPI specification defines a set of mandatory and optional -+operations for the firmware to implement. The ACPI interface also -+allows an administrator to list the supported operations. In QEMU the -+ACPI code is generated by QEMU, yet the firmware needs to implement -+support on a per-operations basis, and different firmwares may support -+a different subset. Therefore, QEMU introduces the virtual memory -+device for PPI where the firmware can indicate which operations it -+supports and ACPI can enable the ones that are supported and disable -+all others.

This --interface requires ACPI and firmware support. The specification can be found at --the following URL: -- --https://trustedcomputinggroup.org/resource/tcg-physical-presence-interface-specification/ -- --PPI enables a system administrator (root) to request a modification to the --TPM upon reboot. The PPI specification defines the operation requests and the --actions the firmware has to take. The system administrator passes the operation --request number to the firmware through an ACPI interface which writes this --number to a memory location that the firmware knows. Upon reboot, the firmware --finds the number and sends commands to the TPM. The firmware writes the TPM --result code and the operation request number to a memory location that ACPI can --read from and pass the result on to the administrator. -- --The PPI specification defines a set of mandatory and optional operations for --the firmware to implement. The ACPI interface also allows an administrator to --list the supported operations. In QEMU the ACPI code is generated by QEMU, yet --the firmware needs to implement support on a per-operations basis, and --different firmwares may support a different subset. Therefore, QEMU introduces --the virtual memory device for PPI where the firmware can indicate which --operations it supports and ACPI can enable the ones that are supported and --disable all others.

With Gluster, buf_align cannot be detected since the actual I/O is - done on Gluster server, and qemu buffer alignment does not matter. - Since we don't have alignment requirement, buf_align=1 is the best - value. - -2.

Using the wrong alignment results in - I/O error. - -3. With Gluster backed by XFS, request_alignment cannot be detected if - reading from unallocated area. In this case we need to use the - correct alignment, and failing to do so results in I/O errors. - -4. With NFS, the server does not use direct I/O, so both buf_align cannot - be detected. In this case we don't need any alignment so we can use - buf_align=1 and request_alignment=1. - -These cases seems to work when storage sector size is 512 bytes, because -the current code starts checking align=512. If the check succeeds -because alignment cannot be detected we use 512. But this does not work -for storage with 4k sector size. - -To determine if we can detect the alignment, we probe first with -align=1. If probing succeeds, maybe there are no alignment requirement -(cases 1, 4) or we are probing unallocated area (cases 2, 3). Since we -don't have any way to tell, we treat this as undetectable alignment. If -probing with align=1 fails with EINVAL, but probing with one of the -expected alignments succeeds, we know that we found a working alignment. - -Practically the alignment requirements are the same for buffer -alignment, buffer length, and offset in file. So in case we cannot -detect buf_align, we can use request alignment. If we cannot detect -request alignment, we can fallback to a safe value.

See below for details of -+ * sequence to be followed. -+ * -+ * data_size: (read/write) -+ * The user application should read data_size to get the size in bytes of -+ * the data copied in the migration region during the _SAVING state and -+ * write the size in bytes of the data copied in the migration region -+ * during the _RESUMING state. -+ * -+ * The format of the migration region is as follows: -+ * ------------------------------------------------------------------ -+ * |vfio_device_migration_info| data section | -+ * | | /////////////////////////////// | -+ * ------------------------------------------------------------------ -+ * ^ ^ -+ * offset 0-trapped part data_offset -+ * -+ * The structure vfio_device_migration_info is always followed by the data -+ * section in the region, so data_offset will always be nonzero. The offset -+ * from where the data is copied is decided by the kernel driver. The data -+ * section can be trapped, mmapped, or partitioned, depending on how the kernel -+ * driver defines the data section. The data section partition can be defined -+ * as mapped by the sparse mmap capability. If mmapped, data_offset must be -+ * page aligned, whereas initial section which contains the -+ * vfio_device_migration_info structure, might not end at the offset, which is -+ * page aligned. The user is not required to access through mmap regardless -+ * of the capabilities of the region mmap. -+ * The vendor driver should determine whether and how to partition the data -+ * section. The vendor driver should return data_offset accordingly. -+ * -+ * The sequence to be followed while in pre-copy state and stop-and-copy state -+ * is as follows: -+ * a. Read pending_bytes, indicating the start of a new iteration to get device -+ * data. Repeated read on pending_bytes at this stage should have no side -+ * effects. -+ * If pending_bytes == 0, the user application should not iterate to get data -+ * for that device. -+ * If pending_bytes > 0, perform the following steps. -+ * b. Read data_offset, indicating that the vendor driver should make data -+ * available through the data section. The vendor driver should return this -+ * read operation only after data is available from (region + data_offset) -+ * to (region + data_offset + data_size). -+ * c. Read data_size, which is the amount of data in bytes available through -+ * the migration region. -+ * Read on data_offset and data_size should return the offset and size of -+ * the current buffer if the user application reads data_offset and -+ * data_size more than once here. -+ * d. Read data_size bytes of data from (region + data_offset) from the -+ * migration region. -+ * e. Process the data. -+ * f. Read pending_bytes, which indicates that the data from the previous -+ * iteration has been read. If pending_bytes > 0, go to step b. -+ * -+ * The user application can transition from the _SAVING|_RUNNING -+ * (pre-copy state) to the _SAVING (stop-and-copy) state regardless of the -+ * number of pending bytes. The user application should iterate in _SAVING -+ * (stop-and-copy) until pending_bytes is 0. -+ * -+ * The sequence to be followed while _RESUMING device state is as follows: -+ * While data for this device is available, repeat the following steps: -+ * a. Read data_offset from where the user application should write data. -+ * b. Write migration data starting at the migration region + data_offset for -+ * the length determined by data_size from the migration source. -+ * c. Write data_size, which indicates to the vendor driver that data is -+ * written in the migration region. Vendor driver must return this write -+ * operations on consuming data. Vendor driver should apply the -+ * user-provided migration region data to the device resume state. -+ * -+ * If an error occurs during the above sequences, the vendor driver can return -+ * an error code for next read() or write() operation, which will terminate the -+ * loop. The user application should then take the next necessary action, for -+ * example, failing migration or terminating the user application. -+ * -+ * For the user application, data is opaque. The user application should write -+ * data in the same order as the data is received and the data should be of -+ * same transaction size at the source. - */ --#define VFIO_REGION_SUBTYPE_IBM_NVLINK2_ATSD (1) -+ -+struct vfio_device_migration_info { -+ __u32 device_state; /* VFIO device state */ -+#define VFIO_DEVICE_STATE_STOP (0) -+#define VFIO_DEVICE_STATE_RUNNING (1 << 0) -+#define VFIO_DEVICE_STATE_SAVING (1 << 1) -+#define VFIO_DEVICE_STATE_RESUMING (1 << 2) -+#define VFIO_DEVICE_STATE_MASK (VFIO_DEVICE_STATE_RUNNING | \ -+ VFIO_DEVICE_STATE_SAVING | \ -+ VFIO_DEVICE_STATE_RESUMING) -+ -+#define VFIO_DEVICE_STATE_VALID(state) \ -+ (state & VFIO_DEVICE_STATE_RESUMING ? \ -+ (state & VFIO_DEVICE_STATE_MASK) == VFIO_DEVICE_STATE_RESUMING : 1) -+ -+#define VFIO_DEVICE_STATE_IS_ERROR(state) \ -+ ((state & VFIO_DEVICE_STATE_MASK) == (VFIO_DEVICE_STATE_SAVING | \ -+ VFIO_DEVICE_STATE_RESUMING)) -+ -+#define VFIO_DEVICE_STATE_SET_ERROR(state) \ -+ ((state & ~VFIO_DEVICE_STATE_MASK) | VFIO_DEVICE_SATE_SAVING | \ -+ VFIO_DEVICE_STATE_RESUMING) -+ -+ __u32 reserved; -+ __u64 pending_bytes; -+ __u64 data_offset; -+ __u64 data_size; -+}; - - /* - * The MSIX mappable capability informs that MSIX data of a BAR can be mmapped -@@ -570,6 +807,7 @@ enum { - - enum { - VFIO_CCW_IO_IRQ_INDEX, -+ VFIO_CCW_CRW_IRQ_INDEX, - VFIO_CCW_NUM_IRQS - }; - -@@ -700,6 +938,43 @@ struct vfio_device_ioeventfd { - - #define VFIO_DEVICE_IOEVENTFD _IO(VFIO_TYPE, VFIO_BASE + 16) - -+/** -+ * VFIO_DEVICE_FEATURE - _IORW(VFIO_TYPE, VFIO_BASE + 17, -+ * struct vfio_device_feature) -+ * -+ * Get, set, or probe feature data of the device.

You can also see in the previous line of the change that this mmap_reserve call only occurs when old_size > new_size. - -Bug: https://bugs.launchpad.net/qemu/+bug/1876373 -Signed-off-by: Jonathan Marler -Reviewded-by: Laurent Vivier -Message-Id: <20200502161225.14346-1-johnnymarler@gmail.com> -Signed-off-by: Laurent Vivier ---- - linux-user/mmap.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - -diff --git a/linux-user/mmap.c b/linux-user/mmap.c -index 46a6e3a7..2a9ca0c3 100644 ---- a/linux-user/mmap.c -+++ b/linux-user/mmap.c -@@ -740,7 +740,7 @@ abi_long target_mremap(abi_ulong old_addr, abi_ulong old_size, - if (prot == 0) { - host_addr = mremap(g2h(old_addr), old_size, new_size, flags); - if (host_addr != MAP_FAILED && reserved_va && old_size > new_size) { -- mmap_reserve(old_addr + old_size, new_size - old_size); -+ mmap_reserve(old_addr + old_size, old_size - new_size); - } - } else { - errno = ENOMEM; --- -2.23.0 - diff --git a/lm32-do-not-leak-memory-on-object_new-object_unref.patch b/lm32-do-not-leak-memory-on-object_new-object_unref.patch deleted file mode 100644 index 7ccc53684bb3d3224757209a4c1710883214fcc8..0000000000000000000000000000000000000000 --- a/lm32-do-not-leak-memory-on-object_new-object_unref.patch +++ /dev/null @@ -1,77 +0,0 @@ -From d50be5295c49be1b6024f5902948b52e683b4c23 Mon Sep 17 00:00:00 2001 -From: lizhengui -Date: Wed, 9 Sep 2020 14:18:35 +0800 -Subject: [PATCH] lm32: do not leak memory on object_new/object_unref -MIME-Version: 1.0 -Content-Type: text/plain; charset=UTF-8 -Content-Transfer-Encoding: 8bit - -Bottom halves and ptimers are malloced, but nothing in these -files is freeing memory allocated by instance_init.

At the time the server -first started sending error messages, the assertion could not be -triggered, because messages were completely under our control. -However, over the years, we have added latent scenarios where a client -could trigger the server to attempt an error message that would -include the client's information if it passed other checks first: - -- requesting NBD_OPT_INFO/GO on an export name that is not present - (commit 0cfae925 in v2.12 echoes the name) - -- requesting NBD_OPT_LIST/SET_META_CONTEXT on an export name that is - not present (commit e7b1948d in v2.12 echoes the name) - -At the time, those were still safe because we flagged names larger -than 256 bytes with a different message; but that changed in commit -93676c88 (v4.2) when we raised the name limit to 4096 to match the NBD -string limit. (That commit also failed to change the magic number -4096 in nbd_negotiate_send_rep_err to the just-introduced named -constant.) So with that commit, long client names appended to server -text can now trigger the assertion, and thus be used as a denial of -service attack against a server. As a mitigating factor, if the -server requires TLS, the client cannot trigger the problematic paths -unless it first supplies TLS credentials, and such trusted clients are -less likely to try to intentionally crash the server. - -We may later want to further sanitize the user-supplied strings we -place into our error messages, such as scrubbing out control -characters, but that is less important to the CVE fix, so it can be a -later patch to the new nbd_sanitize_name. - -Consideration was given to changing the assertion in -nbd_negotiate_send_rep_verr to instead merely log a server error and -truncate the message, to avoid leaving a latent path that could -trigger a future CVE DoS on any new error message. However, this -merely complicates the code for something that is already (correctly) -flagging coding errors, and now that we are aware of the long message -pitfall, we are less likely to introduce such errors in the future, -which would make such error handling dead code. - -Reported-by: Xueqiang Wei -CC: qemu-stable@nongnu.org -Fixes: https://bugzilla.redhat.com/1843684 CVE-2020-10761 -Fixes: 93676c88d7 -Signed-off-by: Eric Blake -Message-Id: <20200610163741.3745251-2-eblake@redhat.com> -Reviewed-by: Vladimir Sementsov-Ogievskiy -(cherry picked from commit 5c4fe018c025740fef4a0a4421e8162db0c3eefd) -Signed-off-by: Eric Blake -Signed-off-by: Eduardo Lima (Etrunko) ---- - nbd/server.c | 21 +++++++++++++++++++-- - tests/qemu-iotests/143 | 4 ++++ - tests/qemu-iotests/143.out | 2 ++ - 3 files changed, 25 insertions(+), 2 deletions(-) - -diff --git a/nbd/server.c b/nbd/server.c -index 2d81248967..115e8f06ed 100644 ---- a/nbd/server.c -+++ b/nbd/server.c -@@ -229,6 +229,19 @@ out: - return ret; - } - -+/* -+ * Return a malloc'd copy of @name suitable for use in an error reply. -+ */ -+static char * -+nbd_sanitize_name(const char *name) -+{ -+ if (strnlen(name, 80) < 80) { -+ return g_strdup(name); -+ } -+ /* XXX Should we also try to sanitize any control characters? */ -+ return g_strdup_printf("%.80s...", name); -+} -+ - /* Send an error reply. - * Return -errno on error, 0 on success. */ - static int GCC_FMT_ATTR(4, 5) -@@ -584,9 +597,11 @@ static int nbd_negotiate_handle_info(NBDClient *client, uint16_t myflags, - - exp = nbd_export_find(name); - if (!exp) { -+ g_autofree char *sane_name = nbd_sanitize_name(name); -+ - return nbd_negotiate_send_rep_err(client, NBD_REP_ERR_UNKNOWN, - errp, "export '%s' not present", -- name); -+ sane_name); - } - - /* Don't bother sending NBD_INFO_NAME unless client requested it */ -@@ -975,8 +990,10 @@ static int nbd_negotiate_meta_queries(NBDClient *client, - - meta->exp = nbd_export_find(export_name); - if (meta->exp == NULL) { -+ g_autofree char *sane_name = nbd_sanitize_name(export_name); -+ - return nbd_opt_drop(client, NBD_REP_ERR_UNKNOWN, errp, -- "export '%s' not present", export_name); -+ "export '%s' not present", sane_name); - } - - ret = nbd_opt_read(client, &nb_queries, sizeof(nb_queries), errp); -diff --git a/tests/qemu-iotests/143 b/tests/qemu-iotests/143 -index f649b36195..d2349903b1 100755 ---- a/tests/qemu-iotests/143 -+++ b/tests/qemu-iotests/143 -@@ -58,6 +58,10 @@ _send_qemu_cmd $QEMU_HANDLE \ - $QEMU_IO_PROG -f raw -c quit \ - "nbd+unix:///no_such_export?socket=$SOCK_DIR/nbd" 2>&1 \ - | _filter_qemu_io | _filter_nbd -+# Likewise, with longest possible name permitted in NBD protocol -+$QEMU_IO_PROG -f raw -c quit \ -+ "nbd+unix:///$(printf %4096d 1 | tr ' ' a)?socket=$SOCK_DIR/nbd" 2>&1 \ -+ | _filter_qemu_io | _filter_nbd | sed 's/aaaa*aa/aa--aa/' - - _send_qemu_cmd $QEMU_HANDLE \ - "{ 'execute': 'quit' }" \ -diff --git a/tests/qemu-iotests/143.out b/tests/qemu-iotests/143.out -index 037d34a409..fc7bab3129 100644 ---- a/tests/qemu-iotests/143.out -+++ b/tests/qemu-iotests/143.out -@@ -3,6 +3,8 @@ QA output created by 143 - {"return": {}} - qemu-io: can't open device nbd+unix:///no_such_export?socket=SOCK_DIR/nbd: Requested export not available - server reported: export 'no_such_export' not present -+qemu-io: can't open device nbd+unix:///aa--aa1?socket=SOCK_DIR/nbd: Requested export not available -+server reported: export 'aa--aa...' not present - {"return": {}} - {"timestamp": {"seconds": TIMESTAMP, "microseconds": TIMESTAMP}, "event": "SHUTDOWN", "data": {"guest": false, "reason": "host-qmp-quit"}} - *** done --- -2.27.0 - diff --git a/net-l2tpv3-Remove-redundant-check-in-net_init_l2tpv3.patch b/net-l2tpv3-Remove-redundant-check-in-net_init_l2tpv3.patch deleted file mode 100644 index a96c178294ea7c2afe5a860f4021efe361a6a18f..0000000000000000000000000000000000000000 --- a/net-l2tpv3-Remove-redundant-check-in-net_init_l2tpv3.patch +++ /dev/null @@ -1,46 +0,0 @@ -From cb6048ace290e770b0ec1a6011209192541d3e8a Mon Sep 17 00:00:00 2001 -From: AlexChen -Date: Fri, 30 Oct 2020 10:46:55 +0800 -Subject: [PATCH] net/l2tpv3: Remove redundant check in net_init_l2tpv3() - -The result has been checked to be NULL before, it cannot be NULL here, -so the check is redundant.

In QEMU, optional CPU features have -+corresponding boolean CPU proprieties that, when enabled, indicate -+that the feature is implemented, and, conversely, when disabled, -+indicate that it is not implemented. An example of an ARM CPU feature -+is the Performance Monitoring Unit (PMU). CPU types such as the -+Cortex-A15 and the Cortex-A57, which respectively implement ARM -+architecture reference manuals ARMv7-A and ARMv8-A, may both optionally -+implement PMUs. For example, if a user wants to use a Cortex-A15 without -+a PMU, then the `-cpu` parameter should contain `pmu=off` on the QEMU -+command line, i.e. `-cpu cortex-a15,pmu=off`. -+ -+As not all CPU types support all optional CPU features, then whether or -+not a CPU property exists depends on the CPU type. For example, CPUs -+that implement the ARMv8-A architecture reference manual may optionally -+support the AArch32 CPU feature, which may be enabled by disabling the -+`aarch64` CPU property. A CPU type such as the Cortex-A15, which does -+not implement ARMv8-A, will not have the `aarch64` CPU property. -+ -+QEMU's support may be limited for some CPU features, only partially -+supporting the feature or only supporting the feature under certain -+configurations. For example, the `aarch64` CPU feature, which, when -+disabled, enables the optional AArch32 CPU feature, is only supported -+when using the KVM accelerator and when running on a host CPU type that -+supports the feature. -+ -+CPU Feature Probing -+=================== -+ -+Determining which CPU features are available and functional for a given -+CPU type is possible with the `query-cpu-model-expansion` QMP command. -+Below are some examples where `scripts/qmp/qmp-shell` (see the top comment -+block in the script for usage) is used to issue the QMP commands. -+ -+(1) Determine which CPU features are available for the `max` CPU type -+ (Note, we started QEMU with qemu-system-aarch64, so `max` is -+ implementing the ARMv8-A reference manual in this case):: -+ -+ (QEMU) query-cpu-model-expansion type=full model={"name":"max"} -+ { "return": { -+ "model": { "name": "max", "props": { -+ "pmu": true, "aarch64": true -+ }}}} -+ -+We see that the `max` CPU type has the `pmu` and `aarch64` CPU features. -+We also see that the CPU features are enabled, as they are all `true`. -+ -+(2) Let's try to disable the PMU:: -+ -+ (QEMU) query-cpu-model-expansion type=full model={"name":"max","props":{"pmu":false}} -+ { "return": { -+ "model": { "name": "max", "props": { -+ "pmu": false, "aarch64": true -+ }}}} -+ -+We see it worked, as `pmu` is now `false`. -+ -+(3) Let's try to disable `aarch64`, which enables the AArch32 CPU feature:: -+ -+ (QEMU) query-cpu-model-expansion type=full model={"name":"max","props":{"aarch64":false}} -+ {"error": { -+ "class": "GenericError", "desc": -+ "'aarch64' feature cannot be disabled unless KVM is enabled and 32-bit EL1 is supported" -+ }} -+ -+It looks like this feature is limited to a configuration we do not -+currently have. -+ -+(4) Let's try probing CPU features for the Cortex-A15 CPU type:: -+ -+ (QEMU) query-cpu-model-expansion type=full model={"name":"cortex-a15"} -+ {"return": {"model": {"name": "cortex-a15", "props": {"pmu": true}}}} -+ -+Only the `pmu` CPU feature is available. -+ -+A note about CPU feature dependencies -+------------------------------------- -+ -+It's possible for features to have dependencies on other features. I.e. -+it may be possible to change one feature at a time without error, but -+when attempting to change all features at once an error could occur -+depending on the order they are processed. It's also possible changing -+all at once doesn't generate an error, because a feature's dependencies -+are satisfied with other features, but the same feature cannot be changed -+independently without error. For these reasons callers should always -+attempt to make their desired changes all at once in order to ensure the -+collection is valid. -+ -+A note about CPU models and KVM -+------------------------------- -+ -+Named CPU models generally do not work with KVM. There are a few cases -+that do work, e.g. using the named CPU model `cortex-a57` with KVM on a -+seattle host, but mostly if KVM is enabled the `host` CPU type must be -+used. This means the guest is provided all the same CPU features as the -+host CPU type has. And, for this reason, the `host` CPU type should -+enable all CPU features that the host has by default. Indeed it's even -+a bit strange to allow disabling CPU features that the host has when using -+the `host` CPU type, but in the absence of CPU models it's the best we can -+do if we want to launch guests without all the host's CPU features enabled. -+ -+Enabling KVM also affects the `query-cpu-model-expansion` QMP command. The -+affect is not only limited to specific features, as pointed out in example -+(3) of "CPU Feature Probing", but also to which CPU types may be expanded. -+When KVM is enabled, only the `max`, `host`, and current CPU type may be -+expanded. This restriction is necessary as it's not possible to know all -+CPU types that may work with KVM, but it does impose a small risk of users -+experiencing unexpected errors.

Only -the main() will change (instantiation option is different). -Also the base address of the TPM-TIS device is going to be -different. on x86 it is located at 0xFED40000 while on ARM -it can be located at any location, discovered through the -device tree description. - -So we put shared test functions in a new object module. -Each test needs to set tpm_tis_base_addr global variable. - -Also take benefit of this move to fix "block comments using -a leading */ on a separate line" checkpatch warnings. - -Signed-off-by: Eric Auger -Reviewed-by: Stefan Berger -Message-id: 20200305165149.618-10-eric.auger@redhat.com -Signed-off-by: Stefan Berger -Signed-off-by: jiangfangjie ---- - tests/Makefile.include | 2 +- - tests/tpm-crb-swtpm-test.c | 4 + - tests/tpm-crb-test.c | 3 + - tests/tpm-tis-swtpm-test.c | 3 + - tests/tpm-tis-test.c | 414 +--------------------------------- - tests/tpm-tis-util.c | 451 +++++++++++++++++++++++++++++++++++++ - tests/tpm-tis-util.h | 23 ++ - tests/tpm-util.c | 3 - - tests/tpm-util.h | 5 + - 9 files changed, 493 insertions(+), 415 deletions(-) - create mode 100644 tests/tpm-tis-util.c - create mode 100644 tests/tpm-tis-util.h - -diff --git a/tests/Makefile.include b/tests/Makefile.include -index c151de64..950b32a2 100644 ---- a/tests/Makefile.include -+++ b/tests/Makefile.include -@@ -667,7 +667,7 @@ tests/tpm-crb-swtpm-test$(EXESUF): tests/tpm-crb-swtpm-test.o tests/tpm-emu.o \ - tests/tpm-crb-test$(EXESUF): tests/tpm-crb-test.o tests/tpm-emu.o $(test-io-obj-y) - tests/tpm-tis-swtpm-test$(EXESUF): tests/tpm-tis-swtpm-test.o tests/tpm-emu.o \ - tests/tpm-util.o tests/tpm-tests.o $(test-io-obj-y) --tests/tpm-tis-test$(EXESUF): tests/tpm-tis-test.o tests/tpm-emu.o $(test-io-obj-y) -+tests/tpm-tis-test$(EXESUF): tests/tpm-tis-test.o tests/tpm-tis-util.o tests/tpm-emu.o $(test-io-obj-y) - tests/test-io-channel-file$(EXESUF): tests/test-io-channel-file.o \ - tests/io-channel-helpers.o $(test-io-obj-y) - tests/test-io-channel-tls$(EXESUF): tests/test-io-channel-tls.o \ -diff --git a/tests/tpm-crb-swtpm-test.c b/tests/tpm-crb-swtpm-test.c -index 5228cb7a..55fdb565 100644 ---- a/tests/tpm-crb-swtpm-test.c -+++ b/tests/tpm-crb-swtpm-test.c -@@ -18,6 +18,10 @@ - #include "libqtest.h" - #include "qemu/module.h" - #include "tpm-tests.h" -+#include "hw/acpi/tpm.h" -+ -+/* Not used but needed for linking */ -+uint64_t tpm_tis_base_addr = TPM_TIS_ADDR_BASE;
