| * qemu-log: new option -dfilter to limit outputAlex Bennée2016-03-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging big programs or system emulation sometimes you want both the verbosity of cpu,exec et all but don't want to generate lots of logs for unneeded stuff. This patch adds a new option -dfilter which allows you to specify interesting address ranges in the form: -dfilter 0x8000..0x8fff,0xffffffc000080000+0x200,... Then logging code can use the new qemu_log_in_addr_range() function to decide if it will output logging information for the given range.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Upon instantiating a QCryptoBlock object, it will read the encryption header and extract the encryption keys. It is then possible to call methods to encrypt/decrypt data buffers. There is also a mode whereby it will create/initialize a new encryption header on a previously unformatted volume. The initial framework comes with support for the legacy QCow AES based encryption.

* | blockdev: Split monitor reference from BB creationMax Reitz2016-03-171-5/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, blk_new() automatically assigned a name to the new BlockBackend and considered it referenced by the monitor. This patch removes the implicit monitor_add_blk() call from blk_new() (and consequently the monitor_remove_blk() call from blk_delete(), too) and thus blk_new() (and related functions) no longer take a BB name argument. In fact, there is only a single point where blk_new()/blk_new_open() is called and the new BB is monitor-owned, and that is in blockdev_init(). Besides thus relieving us from having to invent names for all of the BBs we use in qemu-img, this fixes a bug where qemu cannot create a new image if there already is a monitor-owned BB named "image". If a BB and its BDS tree are created in a single operation, as of this patch the BDS tree will be created before the BB is given a name (whereas it was the other way around before). This results in minor change to the output of iotest 087, whose reference output is amended accordingly. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* | blockdev: Separate BB name managementMax Reitz2016-03-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | Introduce separate functions (monitor_add_blk() and monitor_remove_blk()) which set or unset a BB name. Since the name is equivalent to the monitor's reference to a BB, adding a name the same as declaring the BB to be monitor-owned and removing it revokes this status, hence the function names.

* | qapi: Drop QERR_UNKNOWN_BLOCK_FORMAT_FEATUREMax Reitz2016-03-171-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Just specifying a custom string is simpler in basically all places that used it, and in addition, specifying the BB or node name is something we generally do not do in other error messages when opening a BDS, so we should not do it here. This changes the output for iotest 036 (to the better, in my opinion), so the reference output needs to be changed accordingly.

|/ | | | | | | | | | Later, we will remove bdrv_commit_all() and move its contents here, and in order to replace bdrv_commit_all() calls by calls to blk_commit_all() before doing so, we need to add it as an alias now.
