Subject: [PATCH] rule: collapse set element commands

commit 498a5f0c219d8a118af4f172f248647d9b077101
|
|
||||||
Author: Pablo Neira Ayuso <pablo@netfilter.org>

|
|
||||||
|
|
||||||
rule: collapse set element commands
|
|
||||||
|
|
||||||
Robots might generate a long list of singleton element commands such as:
|
|
||||||
|
|
||||||
add element t s { 1.0.1.0/24 }
|
|
||||||
...
|
|
||||||
add element t s { 1.0.2.0/23 }
|
|
||||||
|
|
||||||
collapse them into one single command before the evaluation step, ie.
|
|
||||||
|
|
||||||
add element t s { 1.0.1.0/24, ..., 1.0.2.0/23 }
|
|
||||||
|
|
||||||
this speeds up overlap detection and set element automerge operations in
|
|
||||||
this worst case scenario.
|
|
||||||
|
|
||||||
Since 3da9643fb9ff9 ("intervals: add support to automerge with kernel
|
|
||||||
elements"), the new interval tracking relies on mergesort. The pattern
|
|
||||||
above triggers the set sorting for each element.
|
|
||||||
|
|
||||||
This patch adds a list to cmd objects that store collapsed commands.
|
|
||||||
Moreover, expressions also contain a reference to the original command,
|
|
||||||
to uncollapse the commands after the evaluation step.
|
|
||||||
|
|
||||||
These commands are uncollapsed after the evaluation step to ensure error
|
|
||||||
reporting works as expected (command and netlink message are mapped
|
|
||||||
1:1).
|
|
||||||
|
|
||||||
For the record:
|
|
||||||
|
|
||||||
- nftables versions <= 1.0.2 did not perform any kind of overlap
|
|
||||||
check for the described scenario above (because set cache only contained
|
|
||||||
elements in the kernel in this case). This is a problem for kernels < 5.7
|
|
||||||
which rely on userspace to detect overlaps.
|
|
||||||
|
|
||||||
- the overlap detection could be skipped for kernels >= 5.7.
|
|
||||||
|
|
||||||
- The extended netlink error reporting available for set elements
|
|
||||||
since 5.19-rc might allow to remove the uncollapse step, in this case,
|
|
||||||
error reporting does not rely on the netlink sequence to refer to the
|
|
||||||
command triggering the problem.

intervals: do not report exact overlaps for new elements
|
|
||||||
|
|
||||||
Two new elements that represent an exact overlap should not trigger an error.
|
|
||||||
|
|
||||||
add table t
|
|
||||||
add set t s { type ipv4_addr; flags interval; }
|
|
||||||
add element t s { 1.0.1.0/24 }
|
|
||||||
...
|
|
||||||
add element t s { 1.0.1.0/24 }
|
|
||||||
|
|
||||||
result in a bogus error.
|
|
||||||
|
|
||||||
# nft -f set.nft
|
|
||||||
set.nft:1002:19-28: Error: conflicting intervals specified
|
|
||||||
add element t s { 1.0.1.0/24 }
|
|
||||||

|
|
||||||
intervals: Do not sort cached set elements over and over again
|
|
||||||
|
|
||||||
When adding element(s) to a non-empty set, code merged the two lists and
|
|
||||||
sorted the result. With many individual 'add element' commands this
|
|
||||||
causes substantial overhead. Make use of the fact that
|
|
||||||
existing_set->init is sorted already, sort only the list of new elements
|
|
||||||
and use list_splice_sorted() to merge the two sorted lists.
|
|
||||||
|
|
||||||
Add set_sort_splice() and use it for set element overlap detection and
|
|
||||||
automerge.
|
|
||||||
|
|
||||||
A test case adding ~25k elements in individual commands completes in
|
|
||||||
about 1/4th of the time with this patch applied.
|
|
||||||
|
|
||||||
Joint work with Pablo.

|
||||||

||||||

Subject: [PATCH] scanner: don't pop active flex scanner scope
|
|
||||||
|
|
||||||
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2113874
|
|

commit 8623772af06103ed4ccca3d07e55afbf3d952d6d
|
|
||||||
Author: Florian Westphal <fw@strlen.de>
|
|

|
||||||
scanner: don't pop active flex scanner scope
|
|
||||||
|
|
||||||
Currently we can pop a flex scope that is still active, i.e. the
|
|
||||||
scanner_pop_start_cond() for the scope has not been done.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
counter ipsec out ip daddr 192.168.1.2 counter name "ipsec_out"
|
|
||||||
|
|
||||||
Here, parser fails because 'daddr' is parsed as STRING, not as DADDR token.
|
|
||||||
|
|
||||||
Bug is as follows:
|
|
||||||
COUNTER changes scope to COUNTER. (COUNTER).
|
|
||||||
Next, IPSEC scope gets pushed, stack is: COUNTER, IPSEC.
|
|
||||||
|
|
||||||
Then, the 'COUNTER' scope close happens. Because active scope has changed,
|
|
||||||
we cannot pop (we would pop the 'ipsec' scope in flex).
|
|
||||||
The pop operation gets delayed accordingly.
|
|
||||||
|
|
||||||
Next, IP gets pushed, stack is: COUNTER, IPSEC, IP, plus the information
|
|
||||||
that one scope closure/pop was delayed.
|
|
||||||
|
|
||||||
Then, the IP scope is closed. Because a pop operation was delayed, we pop again,
|
|
||||||
which brings us back to COUNTER state.
|
|
||||||
|
|
||||||
This is bogus: The pop operation CANNOT be done yet, because the ipsec scope
|
|
||||||
is still open, but the existing code lacks the information to detect this.
|
|
||||||
|
|
||||||
After popping the IP scope, we must remain in IPSEC scope until bison
|
|
||||||
parser calls scanner_pop_start_cond(, IPSEC).
|
|
||||||
|
|
||||||
This adds a counter per flex scope so that we can detect this case.
|
|
||||||
In above case, after the IP scope gets closed, the "new" (previous)
|
|
||||||
scope (IPSEC) will be treated as active and its close is attempted again
|
|
||||||
on the next call to scanner_pop_start_cond().
|
|
||||||
|
|
||||||
After this patch, transition in above rule is:
|
|
||||||
|
|
||||||
push counter (COUNTER)
|
|
||||||
push IPSEC (COUNTER, IPSEC)
|
|
||||||
pop COUNTER (delayed: COUNTER, IPSEC, pending-pop for COUNTER),
|
|
||||||
push IP (COUNTER, IPSEC, IP, pending-pop for COUNTER)
|
|
||||||
pop IP (COUNTER, IPSEC, pending-pop for COUNTER)
|
|
||||||
parse DADDR (we're in IPSEC scope, its valid token)
|
|
||||||
pop IPSEC (pops all remaining scopes).
|
|
||||||
|
|
||||||
We could also resurrect the commit:
|
|
||||||
"scanner: flags: move to own scope", the test case passes with the
|
|
||||||
new scope closure logic.

netlink_delinearize: allow postprocessing on concatenated elements
|
|
||||||
|
|
||||||
Currently there is no case where the individual expressions inside a
|
|
||||||
mapped concatenation need to be munged.
|
|
||||||
|
|
||||||
However, to support proper delinearization for an input like
|
|
||||||
'rule netdev nt nc set update ether saddr . vlan id timeout 5s @macset'
|
|
||||||
|
|
||||||
we need to allow this.
|
|
||||||
|
|
||||||
Right now, this gets listed as:
|
|
||||||
|
|
||||||
update @macset { @ll,48,48 . @ll,112,16 & 0xfff timeout 5s }
|
|
||||||
|
|
||||||
because the ethernet protocol is replaced by vlan beforehand,
|
|
||||||
so we fail to map @ll,48,48 to a vlan protocol.
|
|
||||||
|
|
||||||
Likewise, we can't map the vlan info either because we cannot
|
|
||||||
cope with the 'and' operation properly, nor is it removed.
|
|
||||||
|
|
||||||
Prepare for this by deleting and re-adding so that we do not
|
|
||||||
corrupt the linked list.
|
|
||||||
|
|
||||||
After this, the list can be safely changed and a followup patch
|
|
||||||
can start to delete/reallocate expressions.

netlink_delinearize: postprocess binary ands in concatenations
|
|
||||||
|
|
||||||
Input:
|
|
||||||
update ether saddr . vlan id timeout 5s @macset
|
|
||||||
ether saddr . vlan id @macset
|
|
||||||
|
|
||||||
Before this patch, gets rendered as:
|
|
||||||
update @macset { @ll,48,48 . @ll,112,16 & 0xfff timeout 5s }
|
|
||||||
@ll,48,48 . @ll,112,16 & 0xfff @macset
|
|
||||||
|
|
||||||
After this, listing will show:
|
|
||||||
update @macset { @ll,48,48 . vlan id timeout 5s }
|
|
||||||
@ll,48,48 . vlan id @macset
|
|
||||||
|
|
||||||
The @ll, ... is due to vlan description replacing the ethernet one,
|
|
||||||
so payload decode fails to take the concatenation apart (the ethernet
|
|
||||||
header payload info is matched vs. vlan template).
|
|
||||||
|
|
||||||
This will be adjusted by a followup patch.

|
|
||||||
proto: track full stack of seen l2 protocols, not just cumulative offset
|
|
||||||
|
|
||||||
For input, a cumulative size counter of all pushed l2 headers is enough,
|
|
||||||
because we have the full expression tree available to us.
|
|
||||||
|
|
||||||
For delinearization we need to track all seen l2 headers, else we lose
|
|
||||||
information that we might need at a later time.
|
|
||||||
|
|
||||||
Consider:
|
|
||||||
|
|
||||||
rule netdev nt nc set update ether saddr . vlan id
|
|
||||||
|
|
||||||
during delinearization, the vlan proto_desc replaces the ethernet one,
|
|
||||||
and by the time we try to split the concatenation apart we will search
|
|
||||||
the ether saddr offset vs. the templates for proto_vlan.
|
|
||||||
|
|
||||||
This replaces the offset with an array that stores the protocol
|
|
||||||
descriptions seen.
|
|
||||||
|
|
||||||
Then, if the payload offset is larger than our description, search the
|
|
||||||
l2 stack and adjust the offset until we're within the expected offset
|
|
||||||
boundary.

netlink_delinearize: also postprocess OP_AND in set element context
|
|
||||||
|
|
||||||
Pablo reports:
|
|
||||||
add rule netdev nt y update @macset { vlan id timeout 5s }
|
|
||||||
|
|
||||||
listing still shows the raw expression:
|
|
||||||
update @macset { @ll,112,16 & 0xfff timeout 5s }
|
|
||||||
|
|
||||||
so also cover the 'set element' case.

Subject: [PATCH] evaluate: search stacked header list for matching payload dep

commit 87c3041bfd244aaf39e644d33c0df4fe04079e1c

|
|
||||||
evaluate: search stacked header list for matching payload dep
|
|
||||||
|
|
||||||
"ether saddr 0:1:2:3:4:6 vlan id 2" works, but reverse fails:
|
|
||||||
|
|
||||||
"vlan id 2 ether saddr 0:1:2:3:4:6" will give
|
|
||||||
Error: conflicting protocols specified: vlan vs. ether
|
|
||||||
|
|
||||||
After "proto: track full stack of seen l2 protocols, not just cumulative offset",
|
|
||||||
we have a list of all l2 headers, so search those to see if we had this
|
|
||||||
proto base in the past before rejecting this.

|
|
||||||
src: allow anon set concatenation with ether and vlan
|
|
||||||
|
|
||||||
vlan id uses integer type (which has a length of 0).
|
|
||||||
|
|
||||||
Using it was possible, but listing would assert:
|
|
||||||
python: mergesort.c:24: concat_expr_msort_value: Assertion `ilen > 0' failed.
|
|
||||||
|
|
||||||
There are two reasons for this.
|
|
||||||
First reason is that the udata/typeof information lacks the 'vlan id'
|
|
||||||
part, because internally this is 'payload . binop(payload AND mask)'.
|
|
||||||
|
|
||||||
binop lacks an udata store. It makes little sense to store it,
|
|
||||||
'typeof' keyword expects normal match syntax.
|
|
||||||
|
|
||||||
So, when storing udata, store the left hand side of the binary
|
|
||||||
operation, i.e. the load of the 2-byte key.
|
|
||||||
|
|
||||||
With that resolved, delinerization could work, but concat_elem_expr()
|
|
||||||
would splice 12 bits off the elements value, but it should be 16 (on
|
|
||||||
a byte boundary).

Subject: [PATCH] evaluate: set eval ctx for add/update statements with integer

|
||||||
evaluate: set eval ctx for add/update statements with integer constants
|
|
||||||
|
|
||||||
Eric reports that nft asserts when using integer basetype constants with
|
|
||||||
'typeof' sets. Example:
|
|
||||||
table netdev t {
|
|
||||||
set s {
|
|
||||||
typeof ether saddr . vlan id
|
|
||||||
flags dynamic,timeout
|
|
||||||
}
|
|
||||||
|
|
||||||
chain c { }
|
|
||||||
}
|
|
||||||
|
|
||||||
loads fine. But adding a rule with add/update statement fails:
|
|
||||||
nft 'add rule netdev t c set update ether saddr . 0 @s'
|
|
||||||
nft: netlink_linearize.c:867: netlink_gen_expr: Assertion `dreg < ctx->reg_low' failed.
|
|
||||||
|
|
||||||
When the 'ether saddr . 0' concat expression is processed, there is
|
|
||||||
no set definition available anymore to deduce the required size of the
|
|
||||||
integer constant.
|
|
||||||
|
|
||||||
nft eval step then derives the required length using the data types.
|
|
||||||
'0' has integer basetype, so the deduced length is 0.
|
|
||||||
|
|
||||||
The assertion triggers because serialization step finds that it
|
|
||||||
needs one more register.
|
|
||||||
|
|
||||||
2 are needed to store the ethernet address, another register is
|
|
||||||
needed for the vlan id.
|
|
||||||
|
|
||||||
Update eval step to make the expression context store the set key
|
|
||||||
information when processing the preceeding set reference, then
|
|
||||||
let stmt_evaluate_set() preserve the existing context instead of
|
|
||||||
zeroing it again via stmt_evaluate_arg().
|
|
||||||
|
|
||||||
This makes concat expression evaluation compute the total size
|
|
||||||
needed based on the sets key definition.

||||||
|
|
||||||
monitor: Sanitize startup race condition
|
|
||||||
|
|
||||||
During startup, 'nft monitor' first fetches the current ruleset and then
|
|
||||||
keeps this cache up to date based on received events. This is racey, as
|
|
||||||
any ruleset changes in between the initial fetch and the socket opening
|
|
||||||
are not recognized.
|
|
||||||
|
|
||||||
This script demonstrates the problem:
|
|
||||||
|
|
||||||
| #!/bin/bash
|
|
||||||
|
|
|
||||||
| while true; do
|
|
||||||
| nft flush ruleset
|
|
||||||
| iptables-nft -A FORWARD
|
|
||||||
| done &
|
|
||||||
| maniploop=$!
|
|
||||||
|
|
|
||||||
| trap "kill $maniploop; kill \$!; wait" EXIT
|
|
||||||
|
|
|
||||||
| while true; do
|
|
||||||
| nft monitor rules >/dev/null &
|
|
||||||
| sleep 0.2
|
|
||||||
| kill $!
|
|
||||||
| done
|
|
||||||
|
|
||||||
If the table add event is missed, the rule add event callback fails to
|
|
||||||
deserialize the rule and calls abort().
|
|
||||||
|
|
||||||
Avoid the inconvenient program exit by returning NULL from
|
|
||||||
netlink_delinearize_rule() instead of aborting and make callers check
|
|
||||||
the return value.

netlink_delinearize: fix decoding of concat data element
|
|
||||||
|
|
||||||
Its possible to use update as follows:
|
|
||||||
|
|
||||||
meta l4proto tcp update @pinned { ip saddr . ct original proto-src : ip daddr . ct original proto-dst }
|
|
||||||
|
|
||||||
... but when listing, only the first element of the concatenation is
|
|
||||||
shown.
|
|
||||||
|
|
||||||
Check if the element size is too small and parse subsequent registers as
|
|
||||||
well.

netlink_linearize: fix timeout with map updates
|
|
||||||
|
|
||||||
Map updates can use timeouts, just like with sets, but the
|
|
||||||
linearization step did not pass this info to the kernel.
|
|
||||||
|
|
||||||
meta l4proto tcp update @pinned { ip saddr . ct original proto-src timeout 90s : ip daddr . tcp dport
|
|
||||||
|
|
||||||
Listing this won't show the "timeout 90s" because kernel never saw it to
|
|
||||||
begin with.
|
|
||||||
|
|
||||||
Also update evaluation step to reject a timeout that was set on
|
|
||||||
the data part: Timeouts are only allowed for the key-value pair
|
|
||||||
as a whole.

return 'sizeof(tmp)'. Using this value as index is illegal.

netlink: Fix for potential NULL-pointer deref
|
|
||||||
|
|
||||||
If memory allocation fails, calloc() returns NULL which was not checked
|
|
||||||
for. The code seems to expect zero array size though, so simply
|
|
||||||
replacing this call by one of the x*calloc() ones won't work. So guard
|
|
||||||
the call also by a check for 'len'.

Arguments passed to sizeof() where deemed suspicious by covscan due to

|

the different type. Consistently specify size of an array 'a' using
|
|
||||||
'sizeof(*a) * nmemb'.
|
|
||||||
|
|
||||||
For the statement arrays in stmt_matrix, even use xzalloc_array() since
|
|
||||||
the item count is fixed and therefore can't be zero.
