      crypto/tls: fix a minor MAC vs padding leak · d7df9de5
      David Benjamin authored
      The CBC mode ciphers in TLS are a disaster. By ordering authentication
      and encryption wrong, they are very subtly dependent on details and
      implementation of the padding check, admitting attacks such as POODLE
      and Lucky13.
      
      crypto/tls does not promise full countermeasures for Lucky13 and still
      contains some timing variations. This change fixes one of the easy ones:
      by checking the MAC, then the padding, rather than all at once, there is
      a very small timing variation between bad MAC and (good MAC, bad
      padding).
      
      The consequences depend on the effective padding value used in the MAC
      when the padding is bad. extractPadding simply uses the last byte's
      value, leaving the padding bytes effectively unchecked. This is the
      scenario in SSL 3.0 that led to POODLE. Specifically, the attacker can
      take an input record which uses 16 bytes of padding (a full block) and
      replace the final block with some interesting block. The MAC check will
      succeed with 1/256 probability due to the final byte being 16. This
      again means that after 256 queries, the attacker can decrypt one byte.
      
      To fix this, bitwise AND the two values so they may be checked with one
      branch. Additionally, zero the padding if the padding check failed, to
      make things more robust.

      cmd/compile: fix const declaration group broken with closure · 644543dd
      LE Manh Cuong authored
      In typecheckclosure, a xfunc node will be put to xtop. But that node can
      be shared between multiple closures, like in a const declaration group:
      
      const (
      	x = unsafe.Sizeof(func() {})
      	y
      )
      
      It makes a xfunc node appears multiple times in xtop, causing duplicate
      initLSym run.
      
      To fix this issue, we only do typecheck for xfunc one time, and setup
      closure node earlier in typecheckclosure process.
      
      Fixes #30709

      cmd/go: print package import chains for some build list errors · 2bdbc942
      Jay Conrod authored
      When we construct the build list by loading packages (e.g., in
      "go build", "go list", or "go test"), we may load additional modules
      not mentioned in the original build list. If we encounter an error
      loading one of these modules, mvs.BuildList currently returns a
      BuildListError with a chain of requirments. Unfortunately, this is not
      helpful, since the graph is structured such that these missing modules
      are direct requirements of the main module.
      
      With this change, loader.load keeps track of the package that caused
      each "missing" module to be added. If an error occurs in a missing
      module, the chain of package imports is printed instead of the module
      requirements.

      cmd/go: describe dependencies in build list error messages · f7c96725
      Jay Conrod authored
      mvs.BuildList reports errors with a chain of modules to make it
      clear why the module where the error occurred was part of the
      build. This is a little confusing with "go get -u" since there are
      edges in the module graph for requirements and for updates.
      
      With this change, we now print "requires" or "updates to" between
      each module version in the chain.

      cmd/compile: enable -newescape by default · 996a687e
      Matthew Dempsky authored
      RELNOTE=yes
      
      The new escape analysis pass is more precise, which for most Go code
      should be an improvement. However, it may also break code that
      happened to work before (e.g., code that violated the unsafe.Pointer
      safety rules).
      
      The old escape analysis pass can be re-enabled with "go build
      -gcflags=all=-newescape=false". N.B., it's NOT recommended to mix the
      old and new escape analysis passes such as by omitting "all=". While
      the old and new escape analysis passes use similar and mostly
      compatible metadata, there are cases (e.g., closure handling) where
      they semantically differ and could lead to memory corruption errors in
      compiled programs.
      
      Fixes #23109.

      keys array and then sort the new array again (time complexity is
      O(nlogn)).
      
      The improvement tries to utilize the sorted keys array by searching the
      index and doing an insertion if any (time complexity is O(logn)).

      Transport.DialerAndTLSConfigSupportsHTTP2 was added just earlier
      in CL 130256 but we thought of a better name moments after submitting.
      ForceAttemptHTTP2 is shorter, more direct, and doesn't constrain what
      we can use it with in the future.

      cmd/compile: update escape analysis tests for newescape · a9831633
      Matthew Dempsky authored
      The new escape analysis implementation tries to emit debugging
      diagnostics that are compatible with the existing implementation, but
      there's a handful of cases that are easier to handle by updating the
      test expectations instead.
      
      For regress tests that need updating, the original file is copied to
      oldescapeXXX.go.go with -newescape=false added to the //errorcheck
      line, while the file is updated in place with -newescape=true and new
      test requirements.
      
      Notable test changes:
      
      1) escape_because.go looks for a lot of detailed internal debugging
      messages that are fairly particular to how esc.go works and that I
      haven't attempted to port over to escape.go yet.
      
      2) There are a lot of "leaking param: x to result ~r1 level=-1"
      messages for code like
      
          func(p *int) *T { return &T{p} }
      
      that were simply wrong. Here &T must be heap allocated unconditionally
      (because it's being returned); and since p is stored into it, p
      escapes unconditionally too. esc.go incorrectly reports that p escapes
      conditionally only if the returned pointer escaped.
      
      3) esc.go used to print each "leaking param" analysis result as it
      discovered them, which could lead to redundant messages (e.g., that a
      param leaks at level=0 and level=1). escape.go instead prints
      everything at the end, once it knows the shortest path to each sink.
      
      4) esc.go didn't precisely model direct-interface types, resulting in
      some values unnecessarily escaping to the heap when stored into
      non-escaping interface values.
      
      5) For functions written in assembly, esc.go only printed "does not
      escape" messages, whereas escape.go prints "does not escape" or
      "leaking param" as appropriate, consistent with the behavior for
      functions written in Go.
      
      6) 12 tests included "BAD" annotations identifying cases where esc.go
      was unnecessarily heap allocating something. These are all fixed by
      escape.go.
      
      Updates #23109.

      net/http: introduce DialerAndTLSConfigSupportsHTTP2 in Transport · 94e72005
      Kunpei Sakai authored
      Even when a custom TLS config or custom dialer is specified,
      enables HTTP/2 if DialerAndTLSConfigSupportsHTTP2 is true.
      By this change, avoid automatically enabling HTTP/2 if DialContext is set.
      
      This change also ensures that DefaultTransport still automatically
      enable HTTP/2 as discussed in #14391.

      sigaction is called as part of library mode initializers
      (_rt0_*_lib). Sigaction in turn calls getg, but on Android the TLS

      Add a check for initialization before calling getg.
