This replaces some old Chromium code that tries to minimally disentangle
an arbitrary file descriptor mapping with simpler algorithm, for several
reasons:
1. Do something appropriate when a file descriptor is mapped to the same
fd number in the child; currently they're ignored, which means they'll
be closed if they were close-on-exec. This implementation duplicates
the fd twice in that case, which seems to be uncommon in practice; this
isn't maximally efficient but avoids special-case code.
2. Make this more generally applicable; the previous design is
specialized for arbitrary code running between fork and exec, but we
also want to use this on OS X with posix_spawn, which exposes a very
limited set of operations.
3. Avoid the use of C++ standard library iterators in async signal safe
code; the Chromium developers mention that this is a potential problem in
some debugging implementations that take locks.
4. In general the algorithm is simpler and should be more "obviously
correct"; more concretely, it should get complete coverage just by being
run normally in a debug build.
As a convenient side benefit, CloseSuperfluousFds now takes an arbitrary
predicate for which fds to leave open, which means it can be used in
other code that needs it without creating a fake fd mapping.

We were first allocating and mapping a virtual memory area using mach_vm_allocate
(similar to mmap with MAP_ANON) and then obtaining a shareable capability for the
underlying VM object using mach_make_memory_entry_64. However the memory mapping
is fragmented into multiple objects if it's over 128mb. Larger memory allocations
than 128mb weren't possible. To fix this, we are calling mach_make_memory_entry_64
with MAP_MEM_NAMED_CREATE. That will create a new memory object and return a port
for it.

As part of removing the HangMonitor, I renamed a few things and
reorganized the namespaces to not depend on a HangMonitor

There are three things we want to be true:
a) If the child sends a large value and the parent can't allocate enough space
for it we use an infallible allocation so the parent dies with an OOM.
b) If a fuzzer generates (huge-length, small-data) we don't try to allocate
huge-length bytes; knowing that the read will fail.
c) No fuzzer-specific branches in the core IPC serialization code.
Finally, this makes (huge-length, small-data) consistent with other cases where
the data is potentially truncated: ReadParam returns false.

We can move this information into ProtocolState and save having two
virtual functions for every protocol. Moving some bits out of the
codegen'd IPC code is a nice bonus, though we keep the strange setup
where toplevel protocols have two mChannel member variables.
ProtocolName() is only used for producing error messages and annotating
crash reports. But examining actual crash reports that would have used
the result of ProtocolName() indicates that we can always tell what the
erroring protocol is due to the stack backtrace. So having this virtual
function around just provides duplicate information, and it takes up too
much space in the vtable besides. Let's get rid of it.
lower.py generates repetitious:
SetManager(...);
Register(...); // Or RegisterID.
SetIPCChannel(...);
calls, which are moderately sized, given that the above call sequence
requires virtual calls in several places. Instead of codegenning this
sequence, let's consolidate the sequence into IProtocol and change the
code generator to call into the consolidated function instead.
This function is only overriden in two places, both of which go away
after early beta is done. We shouldn't be paying for its vtable entry
after that point.
The reasoning here is the same as for the protocol register/lookup
functions: these functions are all basic functionality that should not
be overriden by subclasses.
This functionality is base functionality for top-level and non-toplevel
protocols; nobody overrides this stuff, so it's safe to move into
ProtocolState.
IProtocol, which is inherited by every generated IPDL protocol and every
concrete protocol implementation in-tree, has a number of virtual
methods that are only relevant when distinguishing between top-level
protocols (IToplevelProtocol) and managed protocols (everything else).
These virtual methods require pointers in every protocol's vtable, which
is wasteful, and it's also somewhat confusing that many methods exist
but don't really need to be overridable in any useful way.
Let's clean this up, by creating a ProtocolState class to hold methods
that solely differ between top-level protocols and everything else.
This commit does that work and moves Shmem-related methods into this
class as a proof that this can be done in a reasonable way.
This function is just pure bloat when it gets inlined, and it will
disappear on non-Nightly builds anyway. Make it MOZ_NEVER_INLINE so our
size statistics on Nightly are somewhat more reflective of our size
statistics on Release.
This replaces using file_util to open and unlink temporary files
(/dev/shm on Linux, $TMPDIR or /tmp otherwise) with the POSIX shm_open
API, or ashmem on Android (which doesn't implement shm_open).
glibc maps shm_open/shm_unlink to open and unlink in /dev/shm (as does
musl libc), so the Linux situation is mostly unchanged except we aren't
duplicating code from system libraries. Other OSes may (and some do)
use more efficient implementations than temporary files.
FreeBSD's SHM_ANON extension is used if available. Sadly, it's not
standard; it would make this patch much simpler if it were.
This patch changes the shm file names; they now start with "org.mozilla"
instead of "org.chromium" because the original Chromium code is mostly
gone at this point. When running as a Snap package, the required
filename prefix is added; other container/sandbox environments using
AppArmor to restrict the allowed filenames may need to be adjusted.
The shm names now include the creating process's pid, to allow
using sandboxing to prevent interfering with shm belonging to other
applications or other processes within the same browser instance.

The current code is a bit of a mess. This patch does the following.
- Changes the processing from backwards to forwards. This avoids the need for
all the `found` booleans, because if a flag is present multiple times, the
last one will naturally override.
- Tightens up the checking. It now doesn't use assertions, but instead returns
false if any of the options are missing arguments, or have malformed
arguments, or any of the mandatory flags are missing. (It assumes that
-appdir and -profile are optional.)
- Renames the loop variable `idx` as `i`.
- Changes `!strcmp(...)` to `strcmp(...) == 0`, because I find that clearer.
- Avoids a redundant nsCString when handling -appdir.
The patch also tweaks GeckoChildProcessHost::mGroupId, which was buggy. It
holds the appModelUserId argument, which XRE_InitChildProcess() always expects
is present in the command. But it's only set to a non-empty value in
InitWindowsGroupID(), which is only called for plugin processes. So in lots of
cases the appModelUserId argument was missing, and a different argument would
be interpreted as the appModelUserId argument (seemingly without noticeable ill
effect).
The patch changes things to mGroupId defaults to "-", which means it's always
present in the command.
Note: all this explains why the old code for ContentProcess::Init() started
processing from argument aArgc, instead of aArgc-1 as you might expect -- it
had to read one extra arg in order to see the argument following -appdir,
because XRE_InitChildProcess() was decrementing aArgc for the appModelUserId
argument even when that argument wasn't present. The new code for
ContentProcess::Init() doesn't have to read past aArgc-1 because the mGroupId
fix ensures the appModelUserId argument is always present.

This patch replaces the large -intPrefs/-boolPrefs/-stringPrefs flags with
a short-lived, anonymous, shared memory segment that is used to pass the early
prefs.
Removing the bloat from the command line is nice, but more important is the
fact that this will let us pass more prefs at content process start-up, which
will allow us to remove the early/late prefs split (bug 1436911).
Although this mechanism is only used for prefs, it's conceivable that it could
be used for other data that must be received very early by children, and for
which the command line isn't ideal.
Notable details:
- Much of the patch deals with the various platform-specific ways of passing
handles/fds to children.
- Linux and Mac: we use a fixed fd (8) in combination with the new
GeckoChildProcessHost::AddFdToRemap() function (which ensures the child
won't close the fd).
- Android: like Linux and Mac, but the handles get passed via "parcels" and
we use the new SetPrefsFd() function instead of the fixed fd.
- Windows: there is no need to duplicate the handle because Windows handles
are system-wide. But we do use the new
GeckoChildProcessHost::AddHandleToShare() function to add it to the list of
inheritable handles. We also ensure that list is processed on all paths
(MOZ_SANDBOX with sandbox, MOZ_SANDBOX without sandbox, non-MOZ_SANDBOX) so
that the handles are marked as inheritable. The handle is passed via the
-prefsHandle flag.
The -prefsLen flag is used on all platforms to indicate the size of the
shared memory segment.
- The patch also moves the serialization/deserialization of the prefs in/out of
the shared memory into libpref, which is a better spot for it. (This means
Preferences::MustSendToContentProcesses() can be removed.)

This changes the lifecycle and API for TextureReadLock to fix file descriptor exhaustion
crashes. These changes are partially superficial and mostly align the API of TextureReadLocks
with their actual usage.
The changes are:
1. Create the TextureReadLock in the TextureClient constructor so it's available before IPC creation
a. This is superficial as EnableReadLock was always called before IPC creation
2. Send the ReadLockDescriptor in the PTextureConstructor message and close the file handle
3. Receive the ReadLockDescriptor in TextureHost and close the file handle
4. Send a boolean flag in layer transactions if the texture is read locked instead of a descriptor
5. Use a boolean flag in TextureHost to determine if the ReadLock must be unlocked instead of a nullptr
I believe that we can remove the InitReadLocks code from LayerTransaction as that was added to
prevent file descriptor limits in IPDL messages and is no longer needed with this change. But
that is a non-essential change and this patch is already big enough.

MainThreadInvoker queues both a Gecko runnable and an APC to the main thread to deal with different ways in which the main thread can block.
However, the main thread doesn't check for APCs very often any more.
This means that the APC's reference to the SyncRunnable doesn't get cleaned up for a long time, thus leaking memory.
To work around this, we:
1. Queue an APC wich does the actual work.
2. Post a Gecko runnable (which always runs).
If the APC hasn't run, the Gecko runnable runs it.

When an object is aggregated, doing a QI to anything other than IUnknown on the inner object AddRefs the outer object.
Thus, before releasing our reference to the inner IUnknown (and thus destroying it), we *must* release any references to interfaces queried from it.
Otherwise, any pointers to interfaces of the inner object would be invalidated.

These conditions are rare and do indicate a problem which breaks accessibility.
However, we aren't getting any closer to diagnosing these as a result of these crashes, so they cause user pain without any gain to us.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
