2021-01-27block: Separate blk_is_writable() and blk_supports_write_perm()Kevin Wolf
Currently, blk_is_read_only() tells whether a given BlockBackend can only be used in read-only mode because its root node is read-only. Some callers actually try to answer a slightly different question: Is the BlockBackend configured to be writable, by taking write permissions on the root node? This can differ, for example, for CD-ROM devices which don't take write permissions, but may be backed by a writable image file. scsi-cd allows write requests to the drive if blk_is_read_only() returns false. However, the write request will immediately run into an assertion failure because the write permission is missing. This patch introduces separate functions for both questions. blk_supports_write_perm() answers the question whether the block node/image file can support writable devices, whereas blk_is_writable() tells whether the BlockBackend is currently configured to be writable. All calls of blk_is_read_only() are converted to one of the two new functions.

2021-01-26block/block-copy: add ratelimit to block-copyVladimir Sementsov-Ogievskiy
We are going to directly use one async block-copy operation for backup job, so we need rate limiter. We want to maintain current backup behavior: only background copying is limited and copy-before-write operations only participate in limit calculation. Therefore we need one rate limiter for block-copy state and boolean flag for block-copy call state for actual limitation. Note, that we can't just calculate each chunk in limiter after successful copying: it will not save us from starting a lot of async sub-requests which will exceed limit too much. Instead let's use the following scheme on sub-request creation: 1. If at the moment limit is not exceeded, create the request and account it immediately. 2. If at the moment limit is already exceeded, drop create sub-request and handle limit instead (by sleep). With this approach we'll never exceed the limit more than by one sub-request (which pretty much matches current backup behavior). Note also, that if there is in-flight block-copy async call, block_copy_kick() should be used after set-speed to apply new setup faster. For that block_copy_kick() published in this patch.

2021-01-26qapi: backup: add perf.use-copy-range parameterVladimir Sementsov-Ogievskiy
Experiments show, that copy_range is not always making things faster. So, to make experimentation simpler, let's add a parameter. Some more perf parameters will be added soon, so here is a new struct. For now, add new backup qmp parameter with x- prefix for the following reasons: - We are going to add more performance parameters, some will be related to the whole block-copy process, some only to background copying in backup (ignored for copy-before-write operations). - On the other hand, we are going to use block-copy interface in other block jobs, which will need performance options as well.. And it should be the same structure or at least somehow related. So, there are too much unclean things about how the interface and now we need the new options mostly for testing. Let's keep them experimental for a while. In do_backup_common() new x-perf parameter handled in a way to make further options addition simpler. We add use-copy-range with default=true, and we'll change the default in further patch, after moving backup to use block-copy.

2021-01-26qapi: block-stream: add "bottom" argumentVladimir Sementsov-Ogievskiy
The code already don't freeze base node and we try to make it prepared for the situation when base node is changed during the operation. In other words, block-stream doesn't own base node. Let's introduce a new interface which should replace the current one, which will in better relations with the code. Specifying bottom node instead of base, and requiring it to be non-filter gives us the following benefits: - drop difference between above_base and base_overlay, which will be renamed to just bottom, when old interface dropped - clean way to work with parallel streams/commits on the same backing chain, which otherwise become a problem when we introduce a filter for stream job - cleaner interface. Nobody will surprised the fact that base node may disappear during block-stream, when there is no word about "base" in the interface.

Prior to 2a4b472c3c, sys/signal.h was only included on OpenBSD (apart from two .c files). The POSIX standard location for this header is just <signal.h> and in fact, OpenBSD's signal.h includes sys/signal.h itself. Unconditionally including <sys/signal.h> on musl causes warnings for just about every source file: /usr/include/sys/signal.h:1:2: warning: #warning redirecting incorrect #include <sys/signal.h> to <signal.h> [-Wcpp] 1 | #warning redirecting incorrect #include <sys/signal.h> to <signal.h> | ^~~~~~~ Since there don't seem to be any platforms which require including <sys/signal.h> in addition to <signal.h>, and some platforms like Haiku lack it completely, just remove it. Tested building on OpenBSD after removing this include.

2021-01-19target/arm: Implement an IMPDEF pauth algorithmRichard Henderson
Without hardware acceleration, a cryptographically strong algorithm is too expensive for pauth_computepac. Even with hardware accel, we are not currently expecting to link the linux-user binaries to any crypto libraries, and doing so would generally make the --static build fail. So choose XXH64 as a reasonably quick and decent hash.

Make the next_irq function be GPIO inputs to the NEXT_PC device, rather than a freestanding set of qemu_irq lines.

2021-01-19spapr: Improve handling of memory unplug with old guestsGreg Kurz
Since commit 1e8b5b1aa16b ("spapr: Allow memory unplug to always succeed") trying to unplug memory from a guest that doesn't support it (eg. rhel6) no longer generates an error like it used to. Instead, it leaves the memory around : only a subsequent reboot or manual use of drmgr within the guest can complete the hot-unplug sequence. A flag was added to SpaprMachineClass so that this new behavior only applies to the default machine type. We can do better. CAS processes all pending hot-unplug requests. This means that we don't really care about what the guest supports if the hot-unplug request happens before CAS. All guests that we care for, even old ones, set enough bits in OV5 that lead to a non-empty bitmap in spapr->ov5_cas. Use that as a heuristic to decide if CAS has already occured or not. Always accept unplug requests that happen before CAS since CAS will process them. Restore the previous behavior of rejecting them after CAS when we know that the guest doesn't support memory hot-unplug. This behavior is suitable for all machine types : this allows to drop the pre_6_0_memory_unplug flag.
