5 netlink: Add NLA_F_NESTED flag to nested attribute
6
7 The mainline kernel v5.2 commit b424e432e770
8 ("netlink: add validation of NLA_F_NESTED flag") imposes strict
validation
9 against nested attribute as follow.
10
11 "
12 Add new validation flag NL_VALIDATE_NESTED which adds three consistency
13 checks of NLA_F_NESTED_FLAG:
14
15 - the flag is set on attributes with NLA_NESTED{,_ARRAY} policy
16 - the flag is not set on attributes with other policies except
NLA_UNSPEC
17 - the flag is set on attribute passed to nla_parse_nested()
18 "
19
20 Sending messages with nested attribute without NLA_F_NESTED would cause
failed
21 validation. For example,
22
23 $ drbdsetup new-resource r0
24 Invalid argument
25
26 This patch adds NLA_F_NESTED flag to all nested attributes.
27
28 Signed-off-by: He Zhe <zhe...@windriver.com>
and a simple:
+#ifndef NLA_F_NESTED
+#define NLA_F_NESTED 0
+#endif
I'll try to fix this in the next days or so.
ADVICE (for other users who find this):
For now mitigation is to stay in the previous kernel and wait until this
bug is either Fix Proposed (-proposed repo) or Fix Released (-updates).
