It uses a sed expression that assumes you can escape - to use it as a literal
(you can't, it has to be first or last char of the range), and assumes
you have to escape delimiters in sed [] context (you don't), and/or that
non-printf escapes become the literal character (they don't, the backslash
is preserved as a literal), meaning it winds up doing "s/[\-\]//" which is
a length 1 range, which is officially undefined behavior according to posix,
and regcomp errors out.
But if we don't accept it (like other implementations do) the perl build
breaks. So collapse [A-A] into just [A].
Testcae taken from perl 5.22.0 file Makefile.SH line 8.
(While we're at it, remove an unused argument from a function.)

Add support for a -Z option to getprop that will either print the
SELabel of a given property if one is provided or print all properties
that have been set along with their SELabel.
Also, correct a memory leak when freeing TT.nv.

This adds the missing "relatime" option, fixes error handling logic (mount
returns 0/-1, not an errno value, and I at least get EACCES rather than
EROFS in the case where the underlying block device is read-only; we should
also probably only try again if the ioctl actually succeeded), and adds the
missing newline in case where we go around and try again read-only.
The test case was "mount -o rw,remount /system" on Android.

and filter out commands that aren't nofork but aren't installed either
(toyflags 0, I.E. recognized aliases like "-sh" called from login).

Unlike the POSIX file(1), there's no magic file here, just hard-coded
common (non-obsolete) file formats. Personally most of my use of file(1)
is as a one-line readelf(1) summarizer, so although I assume a full POSIX
file(1) is out of scope (because just the database would likely be larger
than all the rest of toybox), a subset that only supports in-use file types
actually covers most of the use cases I encounter personally.
Also fix peek_be/peek_le.

Check the fstat(2) return value rather than read uninitialized memory if
it failed, and add a special case for files that claim to be zero-length
but aren't (as is common in /proc on Linux).

clang scan-build flags up this line as being unread, so clearing from code.

don't run on is easier), and use HELP_ instead of help_ for macro prefixes
to avoid name collisions (such as help_exit() the function).
|
|
Pathnames may be longer than the name field in the header, so use
strncpy() instead of xstrncpy() to avoid bailing out.
Also add unit tests to ensure proper handling of short and long
pathnames.

Don't rely on ordering of readdir for tests.

When toybox is installed suid root and invoked by a non-root user for
commands which do not require root privileges, it drops the root
privileges during initialization.
However, since commit afba5b8efd the result check of setuid() was
inverted such that it aborted on success, making toybox unusuable for
non-root users.

This isn't a shell builtin, it uses prlimit to target any pid (without -P
it defaults to $PPID, so acts like historical ulimit by default).

Commit 3d33dd80f8cb931e293d7f64c44bc357fec11120 fixed a use of S_ISDIR
on st_dev rather than st_mode in find, but there was another instance
of the same error in cp.

"cat /proc/self/exe && cmp /proc/self/exe" won't see the same file if cat
and cmp aren't both in a toybox multiplexer binary, so snapshot and pick one.

1) Don't try to force re-exec unless we actually dropped permissions.
(Fixes "./toybox mount" when no suid bit on toybox binary, which
previously exited.)
2) Set temporary toys.which value for error reporting.
(Fixes "ln -s toybox mount && ./mount" with CFG_TOYBOX_DEBUG and
no suid bit, which previously segfaulted.)
