That is wrong.

Subject: [PATCH] xtables-restore: Fix parser feed from line buffer
|
|
||||||
|
|
||||||
When called with --noflush, xtables-restore would trip over chain lines:
|
|
||||||
Parser uses strtok() to separate chain name, policy and counters which
|
|
||||||
inserts nul-chars into the source string. Therefore strlen() can't be
|
|
||||||
used anymore to find end of line. Fix this by caching line length before
|
|
||||||
calling xtables_restore_parse_line().

||||||

Subject: [PATCH] xtables-translate: don't fail if help was requested
|
||||||
|
|
||||||
|
If the user called `iptables-translate -h` then we have CMD_NONE and we should gracefully handle
|
||||||
|
this case in do_command_xlate().
|
||||||
|
|
||||||
|
Before this patch, you would see:
|
||||||
|
|
||||||
|
user@debian:~$ sudo iptables-translate -h
|
||||||
|
[..]
|
||||||
|
nft Unsupported command?
|
||||||
|
user@debian:~$ echo $?
|
||||||
|
1
|
||||||
|
|
||||||
|
After this patch:
|
||||||
|
|
||||||
|
user@debian:~$ sudo iptables-translate -h
|
||||||
|
[..]
|
||||||
|
user@debian:~$ echo $?
|
||||||
|
0
|
||||||
|

Subject: [PATCH] libxtables: compiler warning fixes for NO_SHARED_LIBS
|

|
MIME-Version: 1.0
|
||||||
|
Content-Type: text/plain; charset=UTF-8
|
||||||
|
Content-Transfer-Encoding: 8bit
|
||||||
|
|
||||||
|
Fixes two issues with NO_SHARED_LIBS:
|
||||||
|
- #include <dlfcn.h> is ifdef'ed out and thus dlclose()
|
||||||
|
triggers an undeclared function compiler warning
|
||||||
|
- dlreg_add() is unused and thus triggers an unused
|
||||||
|
function warning
|
||||||
|
|
||||||
|
Test: builds without warnings

Subject: [PATCH] xtables-translate: Fix for interface name corner-cases
|
|
||||||
|
|
||||||
There are two special situations xlate_ifname() didn't cover for:
|
|
||||||
|
|
||||||
* Interface name containing '*': This went unchanged, creating a command
|
|
||||||
nft wouldn't accept. Instead translate into '\*' which doesn't change
|
|
||||||
semantics.
|
|
||||||
|
|
||||||
* Interface name being '+': Can't translate into nft wildcard character
|
|
||||||
as nft doesn't accept asterisk-only interface names. Instead decide
|
|
||||||
what to do based on 'invert' value: Skip match creation if false,
|
|
||||||
match against an invalid interface name if true.
|
|
||||||
|
|
||||||
Also add a test to make sure future changes to this behaviour are
|
|
||||||
noticed.

Subject: [PATCH] xtables-translate: Fix for iface++
|
|

||||||
In legacy iptables, only the last plus sign remains special, any
|
|
||||||
previous ones are taken literally. Therefore xtables-translate must not
|
|
||||||
replace all of them with asterisk but just the last one.

When testing host binaries, XT_MULTI variable contains just the program

them, and while being at it also reduce indenting level in two scripts

|
||||||
Subject: [PATCH] xtables-restore: fix for --noflush and empty lines
|
|
||||||
|
|
||||||
Lookahead buffer used for cache requirements estimate in restore
|
|
||||||
--noflush separates individual lines with nul-chars. Two consecutive
|
|
||||||
nul-chars are interpreted as end of buffer and remaining buffer content
|
|
||||||
is skipped.
|
|
||||||
|
|
||||||
Sadly, reading an empty line (i.e., one containing a newline character
|
|
||||||
only) caused double nul-chars to appear in buffer as well, leading to
|
|
||||||
premature stop when reading cached lines from buffer.
|
|
||||||
|
|
||||||
To fix that, make use of xtables_restore_parse_line() skipping empty
|
|
||||||
lines without calling strtok() and just leave the newline character in
|
|
||||||
place. A more intuitive approach, namely skipping empty lines while
|
|
||||||
buffering, is deliberately not chosen as that would cause wrong values
|
|
||||||
in 'line' variable.
|
|
||||||
|
|
||||||
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1400

|
||||||

Subject: [PATCH] iptables-test.py: Fix --host mode
|
|
||||||
|
|
||||||
In some cases, the script still called repo binaries. Avoid this when in
|
|
||||||
--host mode to allow testing without the need to compile sources in
|
|
||||||
beforehand.
|
|
||||||
|
|
||||||
Fixes: 1b5d762c1865e ("iptables-test: Support testing host binaries")

Subject: [PATCH] xtables: Review nft_init()
|
|
||||||
|
|
||||||
Move common code into nft_init(), such as:
|
|
||||||
|
|
||||||
* initial zeroing nft_handle fields
|
|
||||||
* family ops lookup and assignment to 'ops' field
|
|
||||||
* setting of 'family' field
|
|
||||||
|
|
||||||
This requires minor adjustments in xtables_restore_main() so extra field
|
|
||||||
initialization doesn't happen before nft_init() call.
|
|
||||||
|
|
||||||
As a side-effect, this fixes segfaulting xtables-monitor binary when
|
|
||||||
printing rules for trace event as in that code-path 'ops' field wasn't
|
|
||||||
initialized.

Subject: [PATCH] nft: cache: Fix nft_release_cache() under stress
|
|
||||||
|
|
||||||
iptables-nft-restore calls nft_action(h, NFT_COMPAT_COMMIT) for each
|
|
||||||
COMMIT line in input. When restoring a dump containing multiple large
|
|
||||||
tables, chances are nft_rebuild_cache() has to run multiple times.
|
|
||||||
|
|
||||||
If the above happens, consecutive table contents are added to __cache[1]
|
|
||||||
which nft_rebuild_cache() then frees, so next commit attempt accesses
|
|
||||||
invalid memory.
|
|
||||||
|
|
||||||
Fix this by making nft_release_cache() (called after each successful
|
|
||||||
commit) return things into pre-rebuild state again, but keeping the
|
|
||||||
fresh cache copy.
|
|
||||||
|
|
||||||
Fixes: f6ad231d698c7 ("nft: keep original cache in case of ERESTART")

Subject: [PATCH] nft: cache: Fix iptables-save segfault under stress
|
|
||||||
|
|
||||||
If kernel ruleset is constantly changing, code called by
|
|
||||||
nft_is_table_compatible() may crash: For each item in table's chain
|
|
||||||
list, nft_is_chain_compatible() is called. This in turn calls
|
|
||||||
nft_build_cache() to fetch chain's rules. Though if kernel genid has changed
|
|
||||||
meanwhile, cache is flushed and rebuilt from scratch, thereby freeing
|
|
||||||
table's chain list - the foreach loop in nft_is_table_compatible() then
|
|
||||||
operates on freed memory.
|
|
||||||
|
|
||||||
A simple reproducer (may need a few calls):
|
|
||||||
|
|
||||||
| RULESET='*filter
|
|
||||||
| :INPUT ACCEPT [10517:1483527]
|
|
||||||
| :FORWARD ACCEPT [0:0]
|
|
||||||
| :OUTPUT ACCEPT [1714:105671]
|
|
||||||
| COMMIT
|
|
||||||
| '
|
|
||||||
|
|
|
||||||
| for ((i = 0; i < 100; i++)); do
|
|
||||||
| iptables-nft-restore <<< "$RULESET" &
|
|
||||||
| done &
|
|
||||||
| iptables-nft-save
|
|
||||||
|
|
||||||
To fix the problem, basically revert commit ab1cd3b510fa5 ("nft: ensure
|
|
||||||
cache consistency") so that __nft_build_cache() no longer flushes the
|
|
||||||
cache. Instead just record kernel's genid when fetching for the first
|
|
||||||
time. If kernel rule set changes until the changes are committed, the
|
|
||||||
commit simply fails and local cache is being rebuilt.

Subject: [PATCH] ebtables: among: Support mixed MAC and MAC/IP entries
|
|
||||||
|
|
||||||
Powered by Stefano's support for concatenated ranges, a full among match
|
|
||||||
replacement can be implemented. The trick is to add MAC-only elements as
|
|
||||||
a concatenation of MAC and zero-length prefix, i.e. a range from
|
|
||||||
0.0.0.0 till 255.255.255.255.
|
|
||||||
|
|
||||||
Although not quite needed, detection of pure MAC-only matches is left in
|
|
||||||
place. For those, no implicit 'meta protocol' match is added (which is
|
|
||||||
required otherwise at least to keep nft output correct) and no concat
|
|
||||||
type is used for the set.

|
|

Legacy iptables doesn't accept -4 or -6 if they don't match the

|
||||||
symlink's native family. The only exception to that is iptables-restore
|
|
||||||
which simply ignores the lines introduced by non-matching options, which
|
|

is useful to create combined dump files for feeding into both
|
|

iptables-restore and ip6tables-restore.

Subject: [PATCH] nfnl_osf: Fix broken conversion to nfnl_query()
|
|
||||||
|
|
||||||
Due to missing NLM_F_ACK flag in request, nfnetlink code in kernel
|
|
||||||
didn't create an own ACK message but left it upon subsystem to ACK or
|
|
||||||
not. Since nfnetlink_osf doesn't ACK by itself, nfnl_query() got stuck
|
|
||||||
waiting for a reply.
|
|
||||||
|
|
||||||
Whoever did the conversion from deprecated nfnl_talk() obviously didn't
|
|
||||||
even test basic functionality of the tool.

Subject: [PATCH] nfnl_osf: Improve error handling
|
|
||||||
|
|
||||||
For some error cases, no log message was created - hence apart from the
|
|
||||||
return code there was no indication of failing execution.
|
|
||||||
|
|
||||||
If a line load fails, don't abort but continue with the remaining
|
|
||||||
file contents. The current pf.os file in this repository serves as
|
|
||||||
proof-of-concept:
|
|
||||||
|
|
||||||
Lines 700 and 701: Duplicates of lines 698 and 699 because 'W*' and 'W0'
|
|
||||||
parse into the same data.
|
|
||||||
|
|
||||||
Line 704: Duplicate of line 702 because apart from 'W*' and 'W0', only
|
|
||||||
the first three fields on right-hand side are sent to the kernel.
|
|
||||||
|
|
||||||
When loading, these dups are ignored (they would bounce if NLM_F_EXCL
|
|
||||||
was given). Upon deletion, they cause ENOENT response from kernel. In
|
|
||||||
order to align duplicate-tolerance in both modes, just ignore that
|
|
||||||
ENOENT.

|

Loading extensions pollutes 'errno' value, hence before using it to

|
indicate failure it should be sanitized. This was done by the called

function before the parsing/netlink split and not migrated by accident.

Move it into calling code to clarify the connection.

Subject: [PATCH] nft: cache: Reset genid when rebuilding cache
|
|
||||||
|
|
||||||
This is required in order to avoid a cache rebuild loop if
|
|
||||||
iptables-nft-restore is called with '--test' parameter and a dump
|
|
||||||
containing more than a single table.
|
|
||||||
|
|
||||||
If non-zero, __nft_build_cache() never updates genid and therefore the
|
|
||||||
incorrect genid (caused by increment in nft_action()) is never
|
|
||||||
corrected.
|
|
||||||
|
|
||||||
This is a RHEL-only fix, upstream rewrote the whole cache logic which
|
|
||||||
implicitly resolved this problem.
|
|
||||||

||||||

Subject: [PATCH] nft: Fix for '-F' in iptables dumps
|
|
||||||
|
|
||||||
When restoring a dump which contains an explicit flush command,
|
|
||||||
previously added rules are removed from cache and the following commit
|
|
||||||
will try to create netlink messages based on freed memory.
|
|
||||||
|
|
||||||
Fix this by weeding any rule-based commands from obj_list if they
|
|
||||||
address the same chain.

Subject: [PATCH] xshared: Merge some command option-related code
|
||||||
|
|
||||||
|
Add OPT_FRAGMENT define into the enum of other OPT_* defines at the
|
||||||
|
right position and adjust the arptables-specific ones that follow
|
||||||
|
accordingly. Appropriately adjust inverse_for_options array in
|
||||||
|
xtables-arp.c.
|
||||||
|
|
||||||
|
Extend optflags from iptables.c by the arptables values for the sake of
|
||||||
|
completeness, then move it to xshared.h along with NUMBER_OF_OPT
|
||||||
|
definition. As a side-effect, this fixes for wrong ordering of entries
|
||||||
|
in arptables' 'optflags' copy.
|
||||||
|
|
||||||
|
Add arptables-specific bits to commands_v_options table (the speicific
|
||||||
|
options are matches on ARP header fields, just treat them like '-s'
|
||||||
|
option. This is also just a cosmetic change, arptables doesn't have a
|
||||||
|
generic_opt_check() implementation and hence doesn't use such a table.
|
||||||
|
|
||||||
|
With things potentially ready for common use, move commands_v_options
|
||||||
|
table along with generic_opt_check() and opt2char() into xshared.c and
|
||||||
|
drop the local (identical) implementations from iptables.c, ip6tables.c
|
||||||
|
xtables.c and xtables-arp.c. While doing so, fix ordering of entries in
|
||||||
|
that table: the row for CMD_ZERO_NUM was in the wrong position. Since
|
||||||
|
all moved rows though are identical, this had no effect in practice.
|
||||||
|
|
||||||
|

Subject: [PATCH] nft: cache: Make nft_rebuild_cache() respect fake cache
|
|
||||||
|
|
||||||
If transaction needed a refresh in nft_action(), restore with flush
|
|
||||||
would fetch a full cache instead of merely refreshing table list
|
|
||||||
contained in "fake" cache.
|
|
||||||
|
|
||||||
To fix this, nft_rebuild_cache() must distinguish between fake cache and
|
|
||||||
full rule cache. Therefore introduce NFT_CL_FAKE to be distinguished
|
|
||||||
from NFT_CL_RULES.

RHEL-only fix: Make nft_rebuild_cache() check 'level' instead of
|
|
||||||
'h->cache_level' as the latter may be reset by __nft_flush_cache().

Subject: [PATCH] nft: Fix selective chain compatibility checks
|
||||||
|
|
||||||
|
Since commit 80251bc2a56ed ("nft: remove cache build calls"), 'chain'
|
||||||
|
parameter passed to nft_chain_list_get() is no longer effective.
|
||||||
|
Before, it was used to fetch only that single chain from kernel when
|
||||||
|
populating the cache. So the returned list of chains for which
|
||||||
|
compatibility checks are done would contain only that single chain.
|
||||||
|
|
||||||
|
Re-establish the single chain compat checking by introducing a dedicated
|
||||||
|
code path to nft_is_chain_compatible() doing so.
|
||||||

||||||
|

Subject: [PATCH] extensions: libxt_conntrack: use bitops for state negation
|
||||||
|
|
||||||
|
Currently, state_xlate_print function prints statemask as comma-separated sequence of enabled
|
||||||
|
statemask flags. But if we have inverted conntrack ctstate condition then we have to use more
|
||||||
|
complex expression because nft not supports syntax like "ct state != related,established".
|
||||||
|
|
||||||
|
Reproducer:
|
||||||
|
$ iptables -A INPUT -d 127.0.0.1/32 -p tcp -m conntrack ! --ctstate RELATED,ESTABLISHED -j DROP
|
||||||
|
$ nft list ruleset
|
||||||
|
...
|
||||||
|
meta l4proto tcp ip daddr 127.0.0.1 ct state != related,established counter packets 0 bytes 0 drop
|
||||||
|
...
|
||||||
|
|
||||||
|
it will fail if we try to load this rule:
|
||||||
|
$ nft -f nft_test
|
||||||
|
../nft_test:6:97-97: Error: syntax error, unexpected comma, expecting newline or semicolon

Subject: [PATCH] nft: Use xtables_malloc() in mnl_err_list_node_add()
|
||||||
|
|
||||||
|
The function called malloc() without checking for memory allocation
|
||||||
|
failure. Simply replace the call by xtables_malloc() to fix that.

The last users vanished back in 2013. There is identical code in

save_rule_details(), but with only a single user there's not much point
|

in keeping the function.

Subject: [PATCH] extensions: libxt_NFLOG: fix `--nflog-prefix` Python
|
||||||
|
test-cases
|
||||||
|
|
||||||
|
The `iptables-save` includes an extra space between `--nflog-prefix` and
|
||||||
|
the prefix.
|
||||||
|
|
||||||
|
The maximum length of prefixes includes the trailing NUL character.
|
||||||
|
|
||||||
|
NFLOG silently truncates prefixes which exceed the maximum length.

Subject: [PATCH] nft: cache: Retry if kernel returns EINTR
|
|
||||||
|
|
||||||
In case of parallel ruleset updates, recvfrom() calls may return EINTR.
|
|
||||||
Due to the fact that cache fetches may get triggered while iterating
|
|
||||||
over cache elements, __nft_build_cache must not restart based on
|
|
||||||
comparing before and after generation ID like upstream does. Instead,
|
|
||||||
just retry the recvfrom() calls until they either succeed or return a
|
|
||||||
different error than EINTR.

Indeed, xtables_ipaddr_to_numeric() returns a pointer to a 20 byte
|
||||||
|
buffer and xtables_ipmask_to_numeric() writes its content into a buffer
|
||||||
|
of same size at offset 1. Yet length of returned string is deterministic
|
||||||
|
as it is an IPv4 address. So shrink it to the minimum of 16 bytes which
|
||||||
|
eliminates the warning as well.

Subject: [PATCH] nft-shared: update context register for bitwise expression
|
||||||
|
|
||||||
|
Update the destination register, otherwise nft_parse_cmp() gives up on
|
||||||
|
interpreting the cmp expression when bitwise sreg != dreg.
|
||||||
|
|
||||||
|
