xtables-monitor: Proper re-init for rule's family
|
|
|
|
When not running for a specific family only (via -4/-6 flags),
|
|
xtables-monitor potentially sees events/traces for all families. To
|
|
correctly parse rules when printing for NEWRULE, DELRULE or TRACE
|
|
messages, nft_handle has to be reinitialized for the rule's family.
|
|
|
|
It is not sufficient to reset nft_handle::ops: Some expression parsers
|
|
rely upon nft_handle::family to be properly set, too (cf. references to
|
|
'ctx->h->family in nft-ruleparse.c). Adjusting the 'afinfo' pointer
|
|
provided by libxtables is even more crucial, as e.g. do_parse() in
|
|
xshared.c relies upon it for the proper optstring.
|
|
|
|
This is actually a day-1 bug in xtables-monitor which surfaced due to
|
|
commit 9075c3aa983d9 ("nft: Increase rule parser strictness"). Therefore
|
|
make this fix the commit it is following-up.
