Subject: [PATCH] evaluate: explicitly deny concatenated types in interval sets |
|
|
|
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1576426 |
|
Upstream Status: nftables commit 9a3d80172a61e |

evaluate: explicitly deny concatenated types in interval sets |
|
|
|
Previously, this triggered a program abort: |
|
|
|
| # nft add table ip t |
|
| # nft add set ip t my_set '{ type ipv4_addr . inet_service ; flags interval ; }' |
|
| # nft add element ip t my_set '{10.0.0.1 . tcp }' |
|
| BUG: invalid range expression type concat |
|
| nft: expression.c:1085: range_expr_value_low: Assertion `0' failed. |
|
|
|
With this patch in place, the 'add set' command above gives an error |
|
message: |
|
|
|
| # nft add set ip t my_set3 '{ type ipv4_addr . inet_service ; flags interval ; }' |
|
| Error: concatenated types not supported in interval sets |
|
| add set ip t my_set3 { type ipv4_addr . inet_service ; flags interval ; } |
|
