ipv6: remove printk

2019-07-27T21:23:48Z

ipv6_find_hdr() prints a non-rate limited error message when it cannot find an ipv6 header at a specific offset. This could be used as a DoS, so just remove it. Signed-off-by: Jonathan Lemon Signed-off-by: David S. Miller

ipv6: Use ipv6_authlen for len

2019-07-11T21:43:25Z

The length of AH header is computed manually as (hp->hdrlen+2)<<2. However, in include/linux/ipv6.h, a macro named ipv6_authlen is already defined for exactly the same job. This commit replaces the manual computation code with the macro. Signed-off-by: yangxingwu Signed-off-by: David S. Miller

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45Z

Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

net: ipv6: Fix typo in ipv6_find_hdr() documentation

inet: whitespace cleanup

2018-02-28T16:43:28Z

Ran simple script to find/remove trailing whitespace and blank lines at EOF because that kind of stuff git whines about and editors leave behind. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

net: ipv6: remove unused code in ipv6_find_hdr()

2017-10-06T04:53:02Z

Storing the left length of skb into 'len' actually has no effect so we can remove it. Signed-off-by: Lin Zhang Signed-off-by: David S. Miller

ipv6: Use ipv6_authlen for len in ipv6_skip_exthdr

2017-09-20T20:45:18Z

In ipv6_skip_exthdr, the lengh of AH header is computed manually as (hp->hdrlen+2)<<2. However, in include/linux/ipv6.h, a macro named ipv6_authlen is already defined for exactly the same job. This commit replaces the manual computation code with the macro. Signed-off-by: Xiang Gao Signed-off-by: David S. Miller

ipv6: re-enable fragment header matching in ipv6_find_hdr

2016-03-03T21:35:20Z

When ipv6_find_hdr is used to find a fragment header (caller specifies target NEXTHDR_FRAGMENT) we erronously return -ENOENT for all fragments with nonzero offset. Before commit 9195bb8e381d, when target was specified, we did not enter the exthdr walk loop as nexthdr == target so this used to work. Now we do (so we can skip empty route headers). When we then stumble upon a frag with nonzero frag_off we must return -ENOENT ("header not found") only if the caller did not specifically request NEXTHDR_FRAGMENT. This allows nfables exthdr expression to match ipv6 fragments, e.g. via nft add rule ip6 filter input frag frag-off gt 0 Fixes: 9195bb8e381d ("ipv6: improve ipv6_find_hdr() to skip empty routing headers") Signed-off-by: Florian Westphal Signed-off-by: David S.

ipv6: coding style: comparison for equality with NULL

2015-03-31T17:51:54Z

The ipv6 code uses a mixture of coding styles. In some instances check for NULL pointer is done as x == NULL and sometimes as !x. !x is preferred according to checkpatch and this patch makes the code consistent by adopting the latter form.
