2015-11-02tpm: Convert to new qapi union layoutEric Blake
We have two issues with our qapi union layout: 1) Even though the QMP wire format spells the tag 'type', the C code spells it 'kind', requiring some hacks in the generator. 2) The C struct uses an anonymous union, which places all tag values in the same namespace as all non-variant members. This leads to spurious collisions if a tag value matches a non-variant member's name. Make the conversion to the new layout for TPM-related code.

2015-06-22qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster
These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

2015-06-22QemuOpts: Wean off qerror_report_err()Markus Armbruster
qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().

2015-06-08QemuOpts: Drop qemu_opts_foreach() parameter abort_on_failureMarkus Armbruster
When the argument is non-zero, qemu_opts_foreach() stops on callback returning non-zero, and returns that value. When the argument is zero, it doesn't stop, and returns the bit-wise inclusive or of all the return values. Funky :) The callers that pass zero could just as well pass one, because their callbacks can't return anything but zero: * qemu_add_globals()'s callback qdev_add_one_global() * qemu_config_write()'s callback config_write_opts() * main()'s callbacks default_driver_check(), drive_enable_snapshot(), vnc_init_func() Drop the parameter, and always stop.

2014-02-17Use error_is_set() only when necessaryMarkus Armbruster
error_is_set(&var) is the same as var != NULL, but it takes whole-program analysis to figure that out. Unnecessarily hard for optimizers, static checkers, and human readers. Dumb it down to obvious. Gets rid of several dozen Coverity false positives. Note that the obvious form is already used in many places.

2013-07-29tpm.c: Don't try to put -1 in a variable of type TpmModelPeter Maydell
The TpmModel type is an enum (valid values 0 and 1), which means the compiler can legitimately decide that comparisons like 'tpm_models[i] == -1' are never true. (For example it could pick 'unsigned char' as its type for representing the enum.) Avoid this issue by using TPM_MODEL_MAX to mark entries in the tpm_models[] array which aren't filled in, instead of -1. This silences a clang warning: tpm.c:43:27: error: comparison of constant -1 with expression of type 'enum TpmModel' is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (tpm_models[i] == -1) { ~~~~~~~~~~~~~ ^ ~~ Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1375096931-13842-1-git-send-email-peter.maydell@linaro.org Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-04-15tpm: reorganize headers and split hardware partPaolo Bonzini
The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
