This backports a fix for the low priority CVE-2021-28831:
decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit
on the huft_build result pointer, with a resultant invalid free or

BUSYBOX_DEFAULT_STATIC_LIBGCC which defauls to off.
Remove date -k patch as it no longer applies. It's also pointless as

Add smalll patch fixing compilation with SELinux. Upstream commit

Refresh config and patches.
Config refresh:

cd ..
./convert_defaults.pl < ../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0/.config > Config-defaults.in
Manual edits needed afterward:
* Config-defaults.in: OpenWrt config symbol IPV6 logic applied to
BUSYBOX_DEFAULT_FEATURE_IPV6
* Config-defaults.in: OpenWrt configTARGET_bcm53xx logic applied to
BUSYBOX_DEFAULT_TRUNCATE (commit 547f1ec)
* editors/Config.in: Add USE_GLIBC dependency to
BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commit f141090)
* shell/Config.in : change at "Options common to all shells" the symbol
SHELL_ASH --> BUSYBOX_CONFIG_SHELL_ASH
(discussion in http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033140.html
Apparently our script does not see the hidden option while
prepending config options with "BUSYBOX_CONFIG_" which leads to a
missed dependency when the options are later evaluated.)

The crypt(3) function is allowed to fail with either EINVAL or ENOSYS when
the given salt is either invalid or when the requested algorithm is not
implemented.
In such a case, libbb's pw_encrypt() function will silently convert the
crypt() NULL return value into an empty string which is then processed
without further errors by utilities such as chpasswd or passwd, causing
them to set an empty password when an unsupported cipher is requested.
Patch the relevant users of pw_encrypt() to abort in case an empty hash
is returned by pw_encrypt() in order to mitigate the problem.

Replace 204-udhcpc_no_msg_dontroute patch by the upstream busybox fix
which removes the code which requires the server ID to be on local
network
Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
This reverts a change made in Sep 2017 [1] which introduced
MSG_DONTROUTE flag to prevent udhcpc from reaching out to servers on a
different subnet. That change violates RFC2131 by forcing fully
configured clients, who got their configurations through an offer
relayed by a DHCP relay, from renewing through a unicast request
directly to the DHCP server, resulting in the client resorting to
boradcasting lease extension requests instead of unicasting them,
further breaking RFC2131.
The problem with MSG_DONTROUTE appears when talking to a properly
configured DHCP server that rejects non-compliant requests. Such server
will reject lease extension attempts sent via broadcast rather than
unicast, as is the case with Finnish ISPs Telia and DNA as well as
Estonian ISP Starman. Once the lease expires without renewal, udhcpc
enters init mode, taking down the interfaces with it, and thus causing
interruption on every lease expiry. On some ISPs (such as the ones
mentioned above) that can be once every 10-20 minutes. The interruptions
appear in the logs as such:
----
udhcpc: sending renew to x.x.x.x
udhcpc: send: Network unreachable
udhcpc: sending renew to 0.0.0.0
udhcpc: sending renew to 0.0.0.0
...
udhcpc: lease lost, entering init state
Interface 'wan' has lost the connection
Interface 'wan' is now down
Network alias 'eth0' link is down
udhcpc: sending select for y.y.y.y
udhcpc: lease of y.y.y.y obtained, lease time 1200
Network alias 'eth0' link is up
Interface 'wan' is now up
----
During lease extension, a fully configured client should be able to
reach out to the server from which it recieved the lease for extension,
regardless in which network it is; that's up to the gateway to find. [2]
This patch ensures that.

In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2,
the tab autocomplete feature of the shell, used to get a list of filenames
in a directory, does not sanitize filenames and results in executing any
escape sequence in the terminal. This could potentially result in code
execution, arbitrary file writes, or other attacks.

The Linux kernel uses two distinct fields to denote the routing table ID in
use by network routes; the 8 bit `rtm_table` member of `struct rtmsg` and the
32 bit `RTA_TABLE` netlink attribute.
If a routing table ID is larger than 255, the `RT_TABLE` attribute must be used
and the `rtm_table` field has to be set to the special `RT_TABLE_UNSPEC` value.
This commit adds a patch which...
- switches the *_n2a() and *_a2n() functions of rt_names.c to use dynamically
sized, name-sorted arrays instead of fixed arrays limited to 1024 slots in
order to support IDs up to 65535
- adds proper handling of high table IDs to iprule.c and iproute.c when
adding, removing and dumping ip rules and network routes
After this change, the Busybox ip applet fully supports IP rules with high ID
numbers, using the same logic as the full iproute2.
