xfrm: Fix kernel panic when flush and dump SPD entries
After flush the SPD entries, dump the SPD entries will cause kernel painc.
Used the following commands to reproduct:
- echo 'spdflush;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
spddump;' | setkey -c
- echo 'spdflush; spddump;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
spddump;' | setkey -c
This is because when flush the SPD entries, the SPD entry is not remove
from the list.
This patch fix the problem by remove the SPD entry from the list.
