This gives us a logging macro that's safe to use in async signal context
(cf. bug 1046210, where we needed this and didn't have it).
This patch also changes one of the format strings to work with
SafeSPrintf's format string dialect; upstream would probably take a
patch to handle those letters, but this is easier.
This does not include the upstream unit tests. Including the tests
in our xul-gtest is possible but not trivial: there are logging
dependencies, and they use a different #include path for gtest.h (which
we'd need to patch).

The original motivation for the Iterator/RemovingIterator split was that
PLDHashTable Checker class would treat them differently. But that didn't end up
happening (see bug 1131308). So this patch merges them. This is a small code
size win now but it will become bigger when I add iterators to nsTHashTable and
nsBaseHashtable.
The only complication is that PLDHashTable::Iter() is now non-const, which is
a problem if you use it in a const method. So I added PLDHashTable::ConstIter()
which is used in just two places. It's a bit of a hack -- effectively a
const_cast -- but I don't think it's too bad.
The doPK11Logout() change is straightforward.
In contrast, the loop in evaporateAllNSSResources() is *weird*. Nevertheless,
this change preserves its behaviour.
This conversion was done with the script:
find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl' | \
egrep -v 'cairo-win32-refptr.h|RefPtr.h|TestRefPtr.cpp' | \
xargs sed -i -e 's/mozilla::TemporaryRef</already_AddRefed</g' \
-e 's/TemporaryRef</already_AddRefed</g'
Manual fixups were performed in the following instances:
- We handled mfbt/RefPtr.h manually so as to not convert TemporaryRef itself
into already_AddRefed.
- The following files had explicit Move() calls added to make up for the lack
of a copy constructor on already_AddRefed:
dom/base/ImageEncoder.cpp
dom/media/MediaTaskQueue.{h,cpp}
dom/media/webaudio/PannerNode.cpp
- A redundant overload for MediaTaskQueue::Dispatch was deleted.
- A few manual fixups were required in mfbt/tests/TestRefPtr.cpp.
- Comments, using declarations, and forward declarations relating to
TemporaryRef in dom/canvas/ and gfx/layers/ were changed to refer to
already_AddRefed.
According to the Baseline Requirements, root certificates MUST NOT
have the extendedKeyUsage extension. The extension is optional for
intermediates and required for end-entity certificates. This change
modifies the test certificates so they're more in line with the BRs.
We can now keep the part of the policy implemented by upcalls to
userspace in the same place as the part of the policy that's handled
entirely in the kernel. This will become more useful in the future
(e.g., bug 930258).
This is more complicated than I'd like it to be, because we don't have
a good way to combine a specific trap function's knowledge that we want
to get a crash dump with the SIGSYS handler's copy of the unprocessed
signal info (which breakpad wants). The bpf_dsl interface requires a
specific trap function type (via the TrapRegistry superclass), so even
if we implement our own registry we can't change what's passed to it.
Normally we could use thread-local storage to get around that, but it's
not async signal safe.
As a result there is an imperfect compromise: the trap function returns
a failure with ENOSYS, Chromium's SIGSYS handler writes it into the
context, our SIGSYS handler reads it back out and uses a copy of
the original signal context for the crash dump. Other error codes
(and returning ENOSYS via the seccomp-bpf policy itself) are handled
normally.
This completely rewrites SandboxFilter.cpp and removes SandboxAssembler.
System calls are now loosely grouped by what they do, now that order
doesn't matter, and most of the intersection the content and media
plugin whitelists is moved into a common superclass. Hopefully this
improves the readability and comprehensibility of the syscall policies.
Also, the macros that take the syscall name are gone, because a plain
case label usually suffices now (the CASES_FOR_thing macros are a little
unsightly, but they're relatively simple), and at one point we saw
strange macro expansion issues with system header files that #define'd
some syscall names.
The signal handling is not migrated yet, so Trap() actions can't be used
yet; the next patch will take care of that, and to keep the intermediate
state working there's a minimal shim.
Bonus fix: non-const global variables use the "g" prefix; "s" is for
static class members and static variables in a function (where the
default is to allocate a separate copy per instance/activation).
Converts test_certificate_usages.js to generate certificates at build time.
Also does miscellaneous cleanup to use modern JS practices.
Since the test_cert_eku-* suite of tests covers the extended key usage extension,
removes superfluous testcases involving EKU.
Finally, renames test_certificate_usages.js to test_cert_keyUsage.js for a more
consistent naming scheme.
This is straightforward mapping of PR_LOG levels to their LogLevel
counterparts:
PR_LOG_ERROR -> LogLevel::Error
PR_LOG_WARNING -> LogLevel::Warning
PR_LOG_WARN -> LogLevel::Warning
PR_LOG_INFO -> LogLevel::Info
PR_LOG_DEBUG -> LogLevel::Debug
PR_LOG_NOTICE -> LogLevel::Debug
PR_LOG_VERBOSE -> LogLevel::Verbose
Instances of PRLogModuleLevel were mapped to a fully qualified
mozilla::LogLevel, instances of PR_LOG levels in #defines were mapped to a
fully qualified mozilla::LogLevel::* level, and all other instances were
mapped to us a shorter format of LogLevel::*.
Bustage for usage of the non-fully qualified LogLevel were fixed by adding
|using mozilla::LogLevel;| where appropriate.
