Lasse Collin 746c471643 liblzma: Remove commented-out code. 2024-02-19 11:58:33 +02:00
Lasse Collin 4ce300ce08 xz: Delete old commented-out code. 2024-02-17 23:07:35 +02:00
Lasse Collin cae9a5e0bf xz: Use stricter pledge(2) and Landlock sandbox.
This makes these sandboxing methods stricter when no files are
created or deleted. That is, it's a middle ground between the
initial sandbox and the strictest single-file-to-stdout sandbox:
this allows opening files for reading but output has to go to stdout.

Lasse Collin 02e3505991 xz: Support Landlock ABI version 4.
Linux 6.7 added support for ABI version 4 which restricts
TCP connections which xz won't need and thus those can be
forbidden now. Since the ABI version is handled at runtime,
supporting version 4 won't cause any compatibility issues.

Note that new enough kernel headers are required to get
version 4 support enabled at build time.

Lasse Collin 374868d81d xz: Move sandboxing code to sandbox.c and improve Landlock sandbox.
Landlock is now always used just like pledge(2) is: first in more
permissive mode and later (under certain common conditions) in
a strict mode that doesn't allow opening more files.

I put pledge(2) first in sandbox.c because it's the simplest API
to use and still somewhat fine-grained for basic applications.
So it's the simplest thing to understand for anyone reading sandbox.c.

Lasse Collin c701a5909a xz: Fix message_init() description.
Also explicitly initialize progress_automatic to make it clear
that it can be read before message_init() sets it. Static variable
was initialized to false by default already so this is only for
clarity.

lzmainfo had been forgotten.

Lasse Collin f1d6b88aef liblzma: Avoid implementation-defined behavior in the RISC-V filter.
GCC docs promise that it works and a few other compilers do
too. Clang/LLVM is documented source code only but unsurprisingly
it behaves the same as others on x86-64 at least. But the
certainly-portable way is good enough here so use that.

Sebastian Andrzej Siewior e9053c9072 liblzma/rangecoder: Exclude x32 from the x86-64 optimisation.
The x32 port has a x86-64 ABI in term of all registers but uses only
32bit pointer like x86-32. The assembly optimisation fails to compile on
x32. Given the state of x32 I suggest to exclude it from the
optimisation rather than trying to fix it.

Lasse Collin 5394a1665b Tests: tuktest.h: Treat Clang separately from GCC.
Don't assume that Clang defines __GNUC__ as the extensions

Clang variants?).

forgotten to be added to Makefile.am.

Lasse Collin cba2edc991 liblzma: Range decoder: Add branchless C code.
It's used only for basic bittrees and fixed-size reverse bittree
because those showed a clear benefit on x86-64 with GCC and Clang.
The other methods were more mixed and thus are commented out but
they should be tested on other archs.
