2020-06-10nbd/server: Avoid long error message assertions CVE-2020-10761Eric Blake
Ever since commit 36683283 (v2.8), the server code asserts that error strings sent to the client are well-formed per the protocol by not exceeding the maximum string length of 4096. 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.

2020-06-10target/i386: fix IEEE x87 floating-point exception raisingJoseph Myers
Most x87 instruction implementations fail to raise the expected IEEE floating-point exceptions because they do nothing to convert the exception state from the softfloat machinery into the exception flags in the x87 status word. There is special-case handling of division to raise the divide-by-zero exception, but that handling is itself buggy: it raises the exception in inappropriate cases (inf / 0 and nan / 0, which should not raise any exceptions, and 0 / 0, which should raise "invalid" instead). Fix this by converting the floating-point exceptions raised during an operation by the softfloat machinery into exceptions in the x87 status word (passing through the existing fpu_set_exception function for handling related to trapping exceptions). There are special cases where some functions convert to integer internally but exceptions from that conversion are not always correct exceptions for the instruction to raise. There might be scope for some simplification if the softfloat exception state either could always be assumed to be in sync with the state in the status word, or could always be ignored at the start of each instruction and just set to 0 then; I haven't looked into that in detail, and it might run into interactions with the various ways the emulation does not yet handle trapping exceptions properly. I think the approach taken here, of saving the softfloat state, setting exceptions there to 0 and then merging the old exceptions back in after carrying out the operation, is conservatively safe.

2020-06-10target/i386: fix fisttpl, fisttpll handling of out-of-range valuesJoseph Myers
The fist / fistt family of instructions should all store the most negative integer in the destination format when the rounded / truncated integer result is out of range or the input is an invalid encoding, infinity or NaN. The fisttpl and fisttpll implementations (32-bit and 64-bit results, truncate towards zero) failed to do this, producing the most positive integer in some cases instead. Fix this by copying the code used to handle this issue for fistpl and fistpll, adjusted to use the _round_to_zero functions for the actual conversion (but without any other changes to that code).

The fbstp implementation fails to check for out-of-range and invalid values, instead just taking the result of conversion to int64_t and storing its sign and low 18 decimal digits. Fix this by checking for an out-of-range result (invalid conversions always result in INT64_MAX or INT64_MIN from the softfloat code, which are large enough to be considered as out-of-range by this code) and storing the packed BCD indefinite encoding in that case.

2020-06-10target/i386: fix fscale handling of rounding precisionJoseph Myers
The fscale implementation uses floatx80_scalbn for the final scaling operation. floatx80_scalbn ends up rounding the result using the dynamic rounding precision configured for the FPU. But only a limited set of x87 floating-point instructions are supposed to respect the dynamic rounding precision, and fscale is not in that set. Fix the implementation to save and restore the rounding precision around the call to floatx80_scalbn.

2020-06-10target/i386: fix fscale handling of infinite exponentsJoseph Myers
The fscale implementation passes infinite exponents through to generic code that rounds the exponent to a 32-bit integer before using floatx80_scalbn. In round-to-nearest mode, and ignoring exceptions, this works in many cases. But it fails to handle the special cases of scaling 0 by a +Inf exponent or an infinity by a -Inf exponent, which should produce a NaN, and because it produces an inexact result for finite nonzero numbers being scaled, the result is sometimes incorrect in other rounding modes. Add appropriate handling of infinite exponents to produce a NaN or an appropriately signed exact zero or infinity as a result.

2020-06-09iotests: 194: wait for migration completion on target tooVladimir Sementsov-Ogievskiy
It is possible, that shutdown on target occurs earlier than migration finish. In this case we crash in bdrv_release_dirty_bitmap_locked() on assertion "assert(!bdrv_dirty_bitmap_busy(bitmap));" as we do have busy bitmap, as bitmap migration is ongoing. We'll fix bitmap migration to gracefully cancel on early shutdown soon. Now let's fix iotest 194 to wait migration completion before shutdown. Note that in this test dest_vm.shutdown() is called implicitly, as vms used as context-providers, see __exit__() method of QEMUMachine class. Actually, not waiting migration finish is a wrong thing, but the test started to crash after commit ae00aa239847682 "iotests: 194: test also migration of dirty bitmap", which added dirty bitmaps here.
