f25d254dfd decompress_gunzip: Fix DoS if gzip is corrupt
On certain corrupt gzip files, huft_build will set the error bit on
the result pointer. If afterwards abort_unzip is called huft_free
might run into a segmentation fault or an invalid pointer to
free(p).

In order to mitigate this, we check in huft_free if the error bit
is set and clear it before the linked list is freed.

v2: Sections numbered less than 10 were always being omitted from
    consideration because splitting "[ 1] .interp" leaves "1]" in
    x[1] where the section name is expected.  This wasn't a problem
    for .rodata (numbered 15 in my testing) but let's fix it anyway.

2d6c175d9b ntpd: decrease INITIAL_SAMPLES from 4 to 3
This reduces initial traffic to NTP servers when a lot of devices boot at once.

Log inspection tells me we agressively burst-poll servers about 5 times
at startup, even though we usually already update clock after second replies.
INITIAL_SAMPLES can probably be even lower, e.g. 2, but let's be conservative
when changing this stuff.

e880c9c100 echo: do not assume that free() leaves errno unmodified
musl libc's mallocng free() may modify errno if kernel does not support
MADV_FREE which causes echo to echo with error when it shouldn't.

Future versions of POSIX[1] will require that free() leaves errno
unmodified but til then, do not rely free() implementation.

Should fix downstream issues:

760b627e2a lineedit: support empty PATH entries in tab completion
Zero-length path prefixes can be specified in PATH as a leading or
trailing colon or two adjacent colons.  POSIX says that the use of
zero-length prefixes to refer to the current directory is a legacy
feature.  Nonetheless the shells in BusyBox respect this feature,
as does 'which'.

Tab-completion of executables using PATH should support this too.

6bdfbc4cb5 libbb: fix '--help' handling in FEATURE_SH_NOFORK=y
Most BusyBox applets respond to the '--help' option by printing
a usage message.  This is normally handled by busybox_main() so
applet main routines don't have support for '--help'.

In standalone shell mode with FEATURE_SH_NOFORK enabled nofork
applets are invoked directly, bypassing busybox_main().  This
results in inconsistent handling of '--help':

- applets which call getopt() report "unrecognized option '--help'"
  and print help anyway;

- realpath says "--help: No such file or directory" and doesn't
  print help;

- usleep says "invalid number '--help'" and doesn't print help.

Avoid inconsistency by checking for '--help' in run_nofork_applet().

Bug found by Ron Yorston.

d40358a1c5 Makefile.flags: fix the OS detection for libresolv
054493350 ("Do not add -lresolv on non-Linux systems") adds a condition
to link with libresolv only on linux systems.

The check requires that CONFIG_UNAME_OSNAME equals Linux. This works only
if the uname applet is enabled. Otherwise, CONFIG_UNAME_OSNAME is empty,
regardless of the platform.

By default, CONFIG_UNAME_OSNAME is the output of uname -o. For most
linux systems, uname -o returns "GNU/Linux" and the check fails. In this
case, linking a static busybox fails because of missing symbols from
libresolv.

This patch uses the output of $CC -dumpmachine to detect the target platform
for which we compile. Both gcc and clang support -dumpmachine. Like the
original patch, we link against libresolv only if our target platform is
linux-based.

5bef6781fa vi: fix range selection by forward character motion
Selection of ranges for change/delete/yank by forward character
motion commands (SPACE or 'l') was incorrect.  The range was
always one character whereas vi allows the size of the range to
be specified.

Fix this by executing the motion command the required number of times.
There is a complication when the range is at the end of a line.  We need
to distinguish between a range which excludes the last character and
one which includes it.  This requires comparing the actual range with
that expected from the command count.  (With the additional quirk that
a command count of zero is equivalent to a command count of one.)

Rewrite index_in_strings() to replace calls to strcmp()/strlen().
With this change searching for valid names in the applet_names

The code has to assume the strings aren't sorted, so will always scan
the entire array when presented with an invalid name.

59120c3303 libbb: code shrink and speed up find_applet_by_name()
find_applet_by_name() determines the appropriate range of applet
indices to check for the given name and performs a linear search in
applet_names[].

Revise the code so the index of the upper bound of the range, 'max',
isn't calculated.  Instead check the value of the first non-matching
character to see if we've reached the end of the range.

This new code speeds up the time to find a valid applet name by 6%
and halves the time to detect that a given name is invalid.  The
average time to detect an invalid name is now the same as for a valid
one.
