Andreas Kling 5a050cb8d1 LibX86: Don't use "if (foo) [[unlikely]] { }" for now (to please clang) 2021-03-09 17:47:28 +01:00
Andreas Kling ad152bfa59 LibWeb: Add a whole bunch of rule classes for the new CSS parser

Andreas Kling 82aea65bd3 UserspaceEmulator: Add fast-path for is<MmapRegion>() 
Don't use default RTTI for these since they are performance-sensitive.
 2021-03-09 15:17:15 +01:00
Andreas Kling 656cd477c2 UserspaceEmulator+LibX86: Sprinkle some [[unlikely]] and ALWAYS_INLINE 2021-03-09 15:10:08 +01:00
Andreas Kling c192b6c61d Emulator: Use libc.so bounds to fast-reject non-malloc addresses 
The auditing code always starts by checking if we're in one of the
ignored code ranges (malloc, free, realloc, syscall, etc.)

To reduce the number of checks needed, we can cache the bounds of
the LibC text segment. This allows us to fast-reject addresses that
cannot possibly be a LibC function.

Andreas Kling 0bf457f715 UserspaceEmulator: Add partial support for some more x87 instructions 
Patch by @bcoles
 2021-03-09 14:30:30 +01:00
Andreas Kling 57142a29a0 UserspaceEmulator: Don't set the MmapRegion malloc-block bit too early 
We were setting it before the malloc metadata had been instantiated.

Fixes #5707.
 2021-03-09 13:57:17 +01:00
Andreas Kling 1381720d1d UserspaceEmulator: Don't assume entire malloc block is chunked 
Accesses in the header (or trailing padding) of a malloc block should
not be associated with any mallocation since only the chunk-sized slots
actually get returned by malloc.

Basically, allow address-to-chunk lookup to fail, and handle such
failures gracefully at call sites.

Fixes #5706.
 2021-03-09 13:29:41 +01:00
Andreas Kling 38fc522f5d UserspaceEmulator: Don't audit accesses in calloc() and libsystem.so 
These generate a lot of false positives and nothing of value.
 2021-03-09 13:24:03 +01:00
Andreas Kling a457b90733 UserspaceEmulator: Tidy up the MallocRegionMetadata construction a bit 
Use designated initializers to make it very obvious what's being set,
and also give the metadata a backpointer to the region for convenience.
 2021-03-09 12:00:53 +01:00
Andreas Kling 915e8dbe71 UserspaceEmulator: Defer marking MmapRegion as malloc block 
We don't want to audit accesses into the region *while* we're setting
up malloc tracking for it. Fetching the chunk size from the header
was tripping up the auditing code.
 2021-03-09 11:41:28 +01:00
Andreas Kling 0b5a915725 UserspaceEmulator: Keep the MMU regions list sorted 2021-03-09 11:31:18 +01:00
Andreas Kling 728d947601 UserspaceEmulator: Remember VM region names for MAP_ANONYMOUS 
For some reason we only remembered the names of MAP_FILE mmap regions.
 2021-03-09 11:31:18 +01:00
Andreas Kling 735a6482ac UserspaceEmulator: Implement sys$set_mmap_name() 2021-03-09 11:31:18 +01:00
Andreas Kling b940dd4fa8 UserspaceEmulator: Never try to mprotect(PROT_EXEC) MmapRegion backing 
We never want to map host memory executable anyway, so let's always
mask off the PROT_EXEC bit.
 2021-03-09 11:31:18 +01:00
Andreas Kling 9588f01739 UserspaceEmulator+LibC: Use sys$emuctl() to pass malloc info to UE 
Get rid of the awkward secret handshake sequence between malloc and UE
and simply use sys$emuctl() to notify UE of malloc, free and realloc.
 2021-03-09 11:31:18 +01:00
Andreas Kling 4faeaf101c LibC: Don't scrub memory in malloc/free when running in UE 
Since UE is keeping track of the heap anyway, we can skip the scrubbing
and drastically improve the speed of malloc and free when emulating.
 2021-03-09 08:59:10 +01:00
Andreas Kling 84725ef3a5 Kernel+UserspaceEmulator: Add sys$emuctl() system call 
This returns ENOSYS if you are running in the real kernel, and some
other result if you are running in UserspaceEmulator.

There are other ways we could check if we're inside an emulator, but
it seemed easier to just ask. :^)

AnicJov 68f2ef1097 Ports: Add libogg 
This library will allow us to port more multimedia programs and games,
since it's a common dependency of such projects. I was looking at
Scummvm's dependencies in particular, with a goal of porting them all
eventually, so that we can have Myst running in Serenity!

Tom 389dddd4b3 Meta: Add a build helper script 
This script automatically manages the toolchain and cmake/ninja folders
making it easier to manage the different target architectures.

Mițca Dumitru efe4845c56 LibM: Implement more rounding functions 
This patch implements the entire rint family, while taking into account
the current rounding mode, and implements ceil, round, trunc, and floor
for types which they weren't before.

Ben Wiederhake 45443f24ec UserspaceEmulator: Enable splitting regions at arbitrary points
