-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: 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

-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
-Fixes: 09cb517949e69 ("xtables-restore: Improve performance of --noflush operation")

-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.

-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

-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] 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.
+
+Fixes: d960a991350ca ("xtables-arp: Integrate OPT_* defines into xshared.h")
+Fixes: 384958620abab ("use nf_tables and nf_tables compatibility interface")

-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.

+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

+
+The `iptables-save` includes an extra space between `--nflog-prefix` and

+
+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.

+Subject: [PATCH] libxtables: Fix for warning in xtables_ipmask_to_numeric
+
+Gcc complains:
+
+| xtables.c: In function 'xtables_ipmask_to_numeric':
+| xtables.c:1491:34: warning: '__builtin___sprintf_chk' may write a terminating nul past the end of the destination [-Wformat-overflow=]
+|  1491 |                 sprintf(buf, "/%s", xtables_ipaddr_to_numeric(mask));
+|       |                                  ^
+
+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.
+
+Fixes: a96166c24eaac ("libxtables: add xtables_ip[6]mask_to_cidr")
+Signed-off-by: Phil Sutter <phil@nwl.cc>

+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.
+
+Fixes: 2c4a34c30cb4 ("iptables-compat: fix address prefix")
+Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
