Subject: [PATCH] libiptc: Fix for another segfault due to chain index NULL
|
||||
pointer
|
||||
|
||||
Chain rename code missed to adjust the num_chains value which is used to
|
||||
calculate the number of chain index buckets to allocate during an index
|
||||
rebuild. So with the right number of chains present, the last chain in a
|
||||
middle bucket being renamed (and ending up in another bucket) triggers
|
||||
an index rebuild based on false data. The resulting NULL pointer index
|
||||
bucket then causes a segfault upon reinsertion.
|
||||
|
||||
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1713
|
||||
Fixes: 64ff47cde38e4 ("libiptc: fix chain rename bug in libiptc")
|
||||

Subject: [PATCH] arptables-nft: remove ARPT_INV flags usage
|
||||
|
||||
ARPT_ and IPT_INV flags are not interchangeable, e.g.:
|
||||
define IPT_INV_SRCDEVADDR 0x0080
|
||||
define ARPT_INV_SRCDEVADDR 0x0010
|
||||
|
||||
as these flags can be tested by libarp_foo.so such checks can yield
|
||||
incorrect results.
|
||||
|
||||
Because arptables-nft uses existing code, e.g. xt_mark, it makes
|
||||
sense to unify this completely by converting the last users of
|
||||
ARPT_INV_ constants.
|
||||
|
||||
Note that arptables-legacy does not do run-time module loading via
|
||||
dlopen(). Functionaliy implemented by "extensions" in the
|
||||
arptables-legacy git tree are built-in, so this doesn't break
|
||||
arptables-legacy binaries.

||||

nft: Fix for broken recover_rule_compat()
|
||||
|
||||
When IPv4 rule generator was changed to emit payload instead of
|
||||
meta expressions for l4proto matches, the code reinserting
|
||||
NFTNL_RULE_COMPAT_* attributes into rules being reused for counter
|
||||
zeroing was broken by accident.
|
||||
|
||||
Make rule compat recovery aware of the alternative match, basically
|
||||
reinstating the effect of commit 7a373f6683afb ("nft: Fix -Z for rules
|
||||
with NFTA_RULE_COMPAT") but add a test case this time to make sure
|
||||
things stay intact.

Drop the boolean, it was meant to disable some existence checks in

any caching is done, the checks in question don't exist anymore so drop

Subject: [PATCH] libxtables: xtoptions: Fix for non-CIDR-compatible hostmasks
|
||||
|
||||
In order to parse the mask, xtopt_parse_hostmask() calls
|
||||
xtopt_parse_plenmask() thereby limiting netmask support to prefix
|
||||
lengths (alternatively specified in IP address notation).
|
||||
|
||||
In order to lift this impractical restriction, make
|
||||
xtopt_parse_plenmask() aware of the fact that xtopt_parse_plen() may
|
||||
fall back to xtopt_parse_mask() which correctly initializes val.hmask
|
||||
itself and indicates non-CIDR-compatible masks by setting val.hlen to
|
||||
-1.
|
||||
|
||||
So in order to support these odd masks, it is sufficient for
|
||||
xtopt_parse_plenmask() to skip its mask building from val.hlen value and
|
||||
take whatever val.hmask contains.

Subject: [PATCH] iptables-legacy: Fix for mandatory lock waiting
|
||||
|
||||
Parameter 'wait' passed to xtables_lock() signals three modes of
|
||||
operation, depending on its value:
|
||||
|
||||
0: --wait not specified, do not wait if lock is busy
|
||||
-1: --wait specified without value, wait indefinitely until lock becomes
|
||||
free
|
||||
>0: Wait for 'wait' seconds for lock to become free, abort otherwise
|
||||
|
||||
Since fixed commit, the first two cases were treated the same apart from
|
||||
calling alarm(0), but that is a nop if no alarm is pending. Fix the code
|
||||
by requesting a non-blocking flock() in the second case. While at it,
|
||||
restrict the alarm setup to the third case only.
