xfrm/compat: Add 32=>64-bit messages translator

2020-09-24T06:53:03Z

Provide the user-to-kernel translator under XFRM_USER_COMPAT, that creates for 32-bit xfrm-user message a 64-bit translation. The translation is afterwards reused by xfrm_user code just as if userspace had sent 64-bit message. Signed-off-by: Dmitry Safonov Signed-off-by: Steffen Klassert

xfrm: Provide API to register translator module

2020-09-24T06:53:03Z

Add a skeleton for xfrm_compat module and provide API to register it in xfrm_state.ko. struct xfrm_translator will have function pointers to translate messages received from 32-bit userspace or to be sent to it from 64-bit kernel. module_get()/module_put() are used instead of rcu_read_lock() as the module will vmalloc() memory for translation. The new API is registered with xfrm_state module, not with xfrm_user as the former needs translator for user_policy set by setsockopt() and xfrm_user already uses functions from xfrm_state.

Steffen Klassert says: ==================== pull request (net): ipsec 2020-06-19 1) Fix double ESP trailer insertion in IPsec crypto offload if netif_xmit_frozen_or_stopped is true. From Huy Nguyen. 2) Merge fixup for "remove output_finish indirection from xfrm_state_afinfo". From Stephen Rothwell. 3) Select CRYPTO_SEQIV for ESP as this is needed for GCM and several other encryption algorithms. Also modernize the crypto algorithm selections for ESP and AH, remove those that are maked as "MUST NOT" and add those that are marked as "MUST" be implemented in RFC 8221. From Eric Biggers.

esp, ah: modernize the crypto algorithm selections

2020-06-15T04:52:16Z

The crypto algorithms selected by the ESP and AH kconfig options are out-of-date with the guidance of RFC 8221, which lists the legacy algorithms MD5 and DES as "MUST NOT" be implemented, and some more modern algorithms like AES-GCM and HMAC-SHA256 as "MUST" be implemented. But the options select the legacy algorithms, not the modern ones. Therefore, modify these options to select the MUST algorithms -- and *only* the MUST algorithms. Also improve the help text. Note that other algorithms may still be explicitly enabled in the kconfig, and the choice of which to actually use is still controlled by userspace. This change only modifies the list of algorithms for which kernel support is guaranteed to be present.

esp: select CRYPTO_SEQIV

2020-06-15T04:52:16Z

Commit f23efcbcc523 ("crypto: ctr - no longer needs CRYPTO_SEQIV") made CRYPTO_CTR stop selecting CRYPTO_SEQIV. This breaks IPsec for most users since GCM and several other encryption algorithms require "seqiv" -- and RFC 8221 lists AES-GCM as "MUST" be implemented. Just make XFRM_ESP select CRYPTO_SEQIV.

esp, ah: consolidate the crypto algorithm selections

2020-06-15T04:52:16Z

Instead of duplicating the algorithm selections between INET_AH and INET6_AH and between INET_ESP and INET6_ESP, create new tristates XFRM_AH and XFRM_ESP that do the algorithm selections, and make these be selected by the corresponding INET* options.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

xfrm: add IPv6 support for espintcp

2020-04-28T09:28:36Z

This extends espintcp to support IPv6, building on the existing code and the new UDPv6 encapsulation support. Most of the code is either reused directly (stream parser, ULP) or very similar to the IPv4 variant (net/ipv6/esp6.c changes). The separation of config options for IPv4 and IPv6 espintcp requires a bit of Kconfig gymnastics to enable the core code. Signed-off-by: Sabrina Dubroca Signed-off-by: Steffen Klassert
