821aa63a09 ncurses: only keep the version with widechar support
Only keep the widechar version of ncurses as libncursesw.so.9

Keep the old name to avoid breaking the ABI compatibility (the non
widechar version libncurses.so.9 is not binary compatible with
libncursesw.so.9) since all ports and base are already only linking
against the widechar version we can simply remove libncurses.so.9

Since the .9 version only lived in the dev branch and never ended in a
release, it is simply removed and not added to any binary compat
package.

Add symlinks to keep build time compatibility for anyone linking against

8c121177f0 casper: convert macros to inline functions
In libcasper, the first argument to the function is a structure that
represents a connection to Casper. On systems without Casper, macros
are used to interpose the Casper functions to standard libc ones.
This may cause errors/warnings that the variable is not used.
With the inline function, there is no such problem.

022ca2fc7f Add aio_writev and aio_readv
POSIX AIO is great, but it lacks vectored I/O functions. This commit
fixes that shortcoming by adding aio_writev and aio_readv. They aren't
part of the standard, but they're an obvious extension. They work just
like their synchronous equivalents pwritev and preadv.

It isn't yet possible to use vectored aiocbs with lio_listio, but that
could be added in the future.

d189a74dfd copy_file_range(2): add recommendation to use large "len"
PR#252358 reported a serious performance problem w.r.t.
cp(1) when copying large non-sparse files.
This problem appears to have been caused by cp(1)
calling copy_file_range(2) with a small "len" argument.

This patch adds a recommendation to use a large "len"

1fc421287d libc: tests: add some tests for cpuset(2)
The cpuset(2) tests should be run as root (require.user properly set) with
>= 3 cpus for maximum coverage. All tests that want to modify the cpuset
don't assume any particular cpu layout (i.e. the first cpu may not be 0, the
last may not be first + count) and the following scenarios are tested:

1.) newset: basic execute cpuset() to grab a new cpuset, make sure the
    assigned cpuset then has a different ID.
2.) transient: create a new cpuset then assign the process its original
    cpuset, ensuring that the one we created is now gone.
3.) deadlk: test assigning an anonymous mask, then resetting the process
    base affinity with 1-cpu overlap w.r.t. the anonymous mask and with
    0-cpu overlap w.r.t. the anonymous mask.
4.) jail_attach_newbase: process attaches to a jail with its own
    cpuset+mask (e.g. cpuset -c -l 1,2 jail -c path=/ command=/bin/sh)
5.) jail_attach_newbase_plain: process attaches to a jail with its own
    cpuset (e.g. cpuset -c jail -c path=/ command=/bin/sh)
6.) jail_attach_prevbase: process attaches to a jail with the containing
    jail's root cpuset (e.g. jail -c path=/ command=/bin/sh)
7.) jail_attach_plain: process attaches to a jail with the containing jail's
    root cpuset+mask.
8.) badparent: creates a new cpuset and modifies the anonymous thread mask,
    then setid's back to the original and checks that cpuset_getid() returns
    the expected set.

libcompiler_rt implements certain functions that clang and gcc emit
calls to as part of their codegen (e.g. for extended width math).  Build
it without stack smashing protection (SSP, -fstack-protector) in order
to support building binaries without SSP, especially the dynamic linker.
Besides, SSP is probably not very valuable in this library.

6c2596f00c Change getlocalbase() to not allocate any heap memory
After the commit of the current version, Scott Long pointed out, that an
attacker might be able to cause a use-after-free access if this function
returned the value of the sysctl variable "user.localbase" by freeing
the allocated memory without the cached address being cleared in the
library function.

To resolve this issue, I have proposed the originally suggested version
with a statically allocated buffer in a review (D27370). There was no
feedback on this review and after waiting for more than 2 weeks, the
potential security issue is fixed by this commit. (There was no security
risk in practice, since none of the programs converted to use this
function attempted to free the buffer. The address could only have
pointed into the heap if user.localbase was set to a non-default value,
into r/o data or the environment, else.)

This version uses a static buffer of size LOCALBASE_CTL_LEN, which
defaults to MAXPATHLEN. This does not increase the memory footprint
of the library at this time, since its data segment grows from less
than 7 KB to less than 8 KB, i.e. it will get two 4 KB pages on typical
architectures, anyway.

Compiling with LOCALBASE_CTL_LEN defined as 0 will remove the code
that accesses the sysctl variable, values between 1 and MAXPATHLEN-1
will limit the maximum size of the prefix. When built with such a
value and if too large a value has been configured in user.localbase,
the value defined as ILLEGAL_PREFIX will be returned to cause any
file operations on that result to fail. (Default value is "/dev/null/",
the review contained "/\177", but I assume that "/dev/null" exists and
can not be accessed as a directory. Any other string that can be assumed
not be a valid path prefix could be used.)

I do suggest to use LOCALBASE_CTL_LEN to size the in-kernel buffer for
the user.localbase variable, too. Doing this would guarantee that the
result always fit into the buffer in this library function (unless run
on a kernel built with a different buffer size.)

The function always returns a valid string, and only in case it is built
with a small static buffer and run on a system with too large a value in
user.localbase, the ILLEGAL_PREFIX will be returned, effectively causing
the created path to be non-existent.
