nft: crash in describe?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Greetings. 

I'm seeing a crash here in nft: 

(ask it to describe something like flags, works fine)

% nft describe tcp flags
payload expression, datatype tcp_flag (TCP flag) (basetype bitmask,
integer), 8 bits

pre-defined symbolic constants:
        fin                             0x01
        syn                             0x02
        rst                             0x04
        psh                             0x08
        ack                             0x10
        urg                             0x20
        ecn                             0x40
        cwr                             0x80

(pass anything invalid and boom):

%  nft describe tcp foobar
value expression, datatype inet_proto (Internet protocol) (basetype
integer), 8 bits [1]    2028 segmentation fault (core dumped)  nft
describe tcp foobar

0x0000000000406a84 in handle_free ()
(gdb) where
#0  0x0000000000406a84 in handle_free ()
#1  0x0000000000407822 in cmd_free ()
#2  0x000000000041a3d1 in nft_parse ()
#3  0x0000000000405e40 in nft_run ()
#4  0x0000000000405a98 in main ()

Happy to gather more info if it will help...
