2019-05-31netfilter: xt_HL: prefer skb_ensure_writableFlorian Westphal1-2/+2
Also, make the argument to be only the needed size of the header we're altering, no need to pull in the full packet into linear area. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2018-02-14netfilter: x_tables: remove pr_info where possibleFlorian Westphal1-10/+3
remove several pr_info messages that cannot be triggered with iptables, the check is only to ensure input is sane. iptables(8) already prints error messages in these cases. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2011-07-01netfilter: Reduce switch/case indentJoe Perches1-32/+32
Make the case labels the same indent as the switch. git diff -w shows miscellaneous 80 column wrapping, comment reflowing and a comment for a useless gcc warning for an otherwise unused default: case. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-03-25netfilter: xtables: slightly better error reportingJan Engelhardt1-1/+1
When extended status codes are available, such as ENOMEM on failed allocations, or subsequent functions (e.g. nf_ct_get_l3proto), passing them up to userspace seems like a good idea compared to just always EINVAL. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-03-25netfilter: xtables: change targets to return error codeJan Engelhardt1-5/+5
Part of the transition of done by this semantic patch: // <smpl> @ rule1 @ struct xt_target ops; identifier check; @@ ops.checkentry = check; @@ identifier rule1.check; @@ check(...) { <... -return true; +return 0; ...> } @@ identifier rule1.check; @@ check(...) { <... -return false; +return -EINVAL; ...> } // </smpl> Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-03-25netfilter: xtables: change xt_target.checkentry return typeJan Engelhardt1-2/+2
Restore function signatures from bool to int so that we can report memory allocation failures or similar using -ENOMEM rather than always having to pass -EINVAL back. // <smpl> @@ type bool; identifier check, par; @@ -bool check +int check (struct xt_tgchk_param *par) { ... } // </smpl> Minus the change it does to xt_ct_find_proto.

2009-02-18netfilter: Combine ipt_TTL and ip6t_HL sourceJan Engelhardt1-0/+171
Suggested by: James King <t.james.king@gmail.com> Similarly to commit c9fd49680954714473d6cbd2546d6ff120f96840, merge TTL and HL. Since HL does not depend on any IPv6-specific function, no new module dependencies would arise. With slight adjustments to the Kconfig help text.
