2021-07-08Do not queue zero sized segments.Bhasker Hariharan
Commit 16b751b6c610ec2c5a913cb8a818e9239ee7da71 introduced a bug where writes of zero size would end up queueing a zero sized segment which will cause the sandbox to panic when trying to send a zero sized segment(e.g. after an RTO) as netstack asserts that the all non FIN segments have size > 0. This change adds the check for a zero sized payload back to avoid queueing such segments. The associated test panics without the fix and passes with it. PiperOrigin-RevId: 383677884

2021-07-01Mix checklocks and atomic analyzers.Adin Scannell
This change makes the checklocks analyzer considerable more powerful, adding: * The ability to traverse complex structures, e.g. to have multiple nested fields as part of the annotation. * The ability to resolve simple anonymous functions and closures, and perform lock analysis across these invocations. This does not apply to closures that are passed elsewhere, since it is not possible to know the context in which they might be invoked. * The ability to annotate return values in addition to receivers and other parameters, with the same complex structures noted above. * Ignoring locking semantics for "fresh" objects, i.e. objects that are allocated in the local frame (typically a new-style function). * Sanity checking of locking state across block transitions and returns, to ensure that no unexpected locks are held. Note that initially, most of these findings are excluded by a comprehensive nogo.yaml. The findings that are included are fundamental lock violations. The changes here should be relatively low risk, minor refactorings to either include necessary annotations to simplify the code structure (in general removing closures in favor of methods) so that the analyzer can be easily track the lock state. This change additional includes two changes to nogo itself: * Sanity checking of all types to ensure that the binary and ast-derived types have a consistent objectpath, to prevent the bug above from occurring silently (and causing much confusion). This also requires a trick in order to ensure that serialized facts are consumable downstream. This can be removed with https://go-review.googlesource.com/c/tools/+/331789 merged. * A minor refactoring to isolation the objdump settings in its own package. This was originally used to implement the sanity check above, but this information is now being passed another way. The minor refactor is preserved however, since it cleans up the code slightly and is minimal risk. PiperOrigin-RevId: 382613300

2021-07-01Fix bug with TCP bind w/ SO_REUSEADDR.Bhasker Hariharan
In gVisor today its possible that when trying to bind a TCP socket w/ SO_REUSEADDR specified and requesting the kernel pick a port by setting port to zero can result in a previously bound port being returned. This behaviour is incorrect as the user is clearly requesting a free port. The behaviour is fine when the user explicity specifies a port. This change now checks if the user specified a port when making a port reservation for a TCP port and only returns unbound ports even if SO_REUSEADDR was specified.

2021-06-29Sort children map before hashChong Cai
The unordered map may generate different hash due to its order. The children map needs to be sorted each time before hashing to avoid false verification failure due to the map. Store the sorted children map in verity dentry to avoid sorting it each time verification happens. Also serialize the whole VerityDescriptor struct to hash now that the map is removed from it.
