a67fe1b171 Merge "Add strerrordesc_np() and strerrorname_np()." into main 2023-09-27 22:26:37 +00:00
Elliott Hughes
2109f12c3b Add strerrordesc_np() and strerrorname_np(). 
strerrordesc_np() isn't very useful (being just another name for
strerror()), but strerrorname_np() lets you get "ENOSYS" for ENOSYS,
which will make some of our test assertion messages clearer when we
switch over from strerror().

This also adds `%#m` formatting to all the relevant functions.

4ae4be9263 Clean up how we skip tests when a syscall isn't in the kernel. 
The close_range() test in particular has been confusing a lot of
partners. I think the sys_epoll_test.cpp idiom is the clearest of the
ones in use, so let's use that everywhere. (I haven't actually touched
the SysV IPC tests, because if we do touch them, _deleting_ them --
since all those syscalls are not allowed on Android -- is probably the
change to be made!)

I'm on the fence about factoring this idiom out into a macro. There
should never be too many of these, and we should probably be removing
them? Is anyone still running the current bionic tests on 4.3 kernels
without membarrier(2), and if they are --- why?!

For now though, I haven't removed any of our existing tests; I've just
moved them over to the sys_epoll_test.cpp style.

6711d21230 <sys/statvfs.h>: add a new mount option. 
This flag was added as part of
https://sites.google.com/a/chromium.org/dev/chromium-os/chromiumos-design-docs/hardening-against-malicious-stateful-data#TOC-Restricting-symlink-traversal
in 2020.

Annoyingly, these flags are in include/linux/statvfs.h rather than in
the uapi headers, so we don't get them for free.

95646e6666 Add ASSERT_ERRNO and EXPECT_ERRNO (and use them). 
We've talked about this many times in the past, but partners struggle to
understand "expected 38, got 22" in these contexts, and I always have to
go and check the header files just to be sure I'm sure.

I actually think the glibc geterrorname_np() function (which would
return "ENOSYS" rather than "Function not implemented") would be more
helpful, but I'll have to go and implement that first, and then come
back.

Being forced to go through all our errno assertions did also make me
want to use a more consistent style for our ENOSYS assertions in
particular --- there's a particularly readable idiom, and I'll also come
back and move more of those checks to the most readable idiom.

I've added a few missing `errno = 0`s before tests, and removed a few
stray `errno = 0`s from tests that don't actually make assertions about
errno, since I had to look at every single reference to errno anyway.

30088848fc Consistent qualifier ordering. 
Change our handful of `constexpr static`s to the much more common
`static constexpr`. It's easier to "follow existing style" when there
aren't two existing styles to copy from, and all else being equal,
"majority wins" :-)

5dd1582706 Remove a stray newline. 
err() not only adds its own newline, it'll add the strerror() output
first, so this stray newline messes up the error message. (Seen running
bionic benchmarks not as root, which causes the std_map benchmarks to
fail, which is especially annoying because it ends the whole benchmark
run, not just the specific benchmark, but that's a less obvious fix, so
I'm just fixing the trivial part here!)

740956c856 Greatly reduce the space used by properties filenames. 
These should never be particularly long, but because this code runs
before we can allocate, they have to be fixed size. Bring that size down
to 128 bytes which should be enough for anyone, and which should let us
add some new filenames in less space than we're currently using for one
filename.
