965ae444 - sctp: create udp4 sock and add its encap_rcv

Thu, 29 Oct 2020 07:04:58 +0000

sctp: create udp4 sock and add its encap_rcvThis patch is to add the functions to create/release udp4 sock,and set the sock's encap_rcv to process the incoming udp encapsctp packets. In sctp_udp_rcv(), as we can see, all we need todo is fix the transport header for sctp_rcv(), then it wouldimplement the part of rfc6951#section-5.4: "When an encapsulated packet is received, the UDP header is removed. Then, the generic lookup is performed, as done by an SCTP stack whenever a packet is received, to find the association for the received SCTP packet"Note that these functions will be called in the last patch ofthis patchset when enabling this feature.v1->v2: - Add pr_err() when fails to create udp v4 sock.v2->v3: - Add 'select NET_UDP_TUNNEL' in sctp Kconfig.v3->v4: - No change.v4->v5: - Change to set udp_port to 0 by default.Signed-off-by: Xin Long Acked-by: Marcelo Ricardo Leitner Signed-off-by: Jakub Kicinski List of files: /linux-6.15/net/sctp/Kconfig

a7f7f624 - treewide: replace '---help---' in Kconfig files with 'help'

Sat, 13 Jun 2020 16:50:22 +0000

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, 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 thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux-6.15/net/sctp/Kconfig

net: sctp: get rid of SCTP_DBG_TSNS entirelyAfter having reworked the debugging framework, Neil and Vlad agreed toget rid of the leftover SCTP_DBG_TSNS code for a couple of reasons:We can use systemtap scripts to investigate these things, we now havepr_debug() helpers that make life easier, and if we really need anythingelse besides those tools, we will be forced to come up with somethingbetter than we have there. Therefore, get rid of this ifdef debuggingcode entirely for now.Signed-off-by: Daniel Borkmann CC: Vlad Yasevich CC: Neil Horman Acked-by: Neil Horman Acked-by: Vlad Yasevich Signed-off-by: David S.

bb33381d - net: sctp: rework debugging framework to use pr_debug and friends

Fri, 28 Jun 2013 17:49:40 +0000

net: sctp: rework debugging framework to use pr_debug and friendsWe should get rid of all own SCTP debug printk macros and use the onesthat the kernel offers anyway instead. This makes the code more readableand conform to the kernel code, and offers all the features of dynamicdebbuging that pr_debug() et al has, such as only turning on/off portionsof debug messages at runtime through debugfs. The runtime cost of havingCONFIG_DYNAMIC_DEBUG enabled, but none of the debug statements printing,is negligible [1]. If kernel debugging is completly turned off, then thesestatements will also compile into "empty" functions.While we're at it, we also need to change the Kconfig option as it /now/only refers to the ifdef'ed code portions in outqueue.c that enable furtherdebugging/tracing of SCTP transaction fields. Also, since SCTP_ASSERT codewas enabled with this Kconfig option and has now been removed, wetransform those code parts into WARNs resp. where appropriate BUG_ONs sothat those bugs can be more easily detected as probably not many peoplehave SCTP debugging permanently turned on.To turn on all SCTP debugging, the following steps are needed: # mount -t debugfs none /sys/kernel/debug # echo -n 'module sctp +p' > /sys/kernel/debug/dynamic_debug/controlThis can be done more fine-grained on a per file, per line basis and othersas described in [2].

36a25de2 - sctp: fix Kconfig bug in default cookie hmac selection

Mon, 07 Jan 2013 16:47:46 +0000

sctp: fix Kconfig bug in default cookie hmac selectionCommit 0d0863b02002 ("sctp: Change defaults on cookie hmac selection")added a "choice" to the sctp Kconfig file. It introduced a bug whichled to an infinite loop when while running "make oldconfig".The problem is that the wrong symbol was defined as the default valuefor the choice. Using the correct value gets rid of the infinite loop.Note: if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the inputconfig file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be presentin the generated config file.Signed-off-by: Alex Elder Signed-off-by: Linus Torvalds List of files: /linux-6.15/net/sctp/Kconfig

0d0863b0 - sctp: Change defaults on cookie hmac selection

Fri, 14 Dec 2012 15:22:01 +0000

sctp: Change defaults on cookie hmac selectionRecently I posted commit 3c68198e75 which made selection of the cookie hmacalgorithm selectable. This is all well and good, but Linus noted that itchanges the default config:http://marc.info/?l=linux-netdev&m=135536629004808&w=2I've modified the sctp Kconfig file to reflect the recommended way of makingthis choice, using the thermal driver example specified, and brought thedefaults back into line with the way they were prior to my origional patchAlso, on Linus' suggestion, re-adding ability to select default 'none' hmacalgorithm, so we don't needlessly bloat the kernel by forcing a non-nonedefault. This also led me to note that we won't honor the default nonecondition properly because of how sctp_net_init is encoded. Fix that up aswell.Tested by myself (allbeit fairly quickly). All configuration combinations seemsto work soundly.Signed-off-by: Neil Horman CC: David Miller CC: Linus Torvalds CC: Vlad Yasevich CC: linux-sctp@vger.kernel.orgSigned-off-by: David S.

3c68198e - sctp: Make hmac algorithm selection for cookie generation dynamic

Wed, 24 Oct 2012 09:20:03 +0000

sctp: Make hmac algorithm selection for cookie generation dynamicCurrently sctp allows for the optional use of md5 of sha1 hmac algorithms togenerate cookie values when establishing new connections via two build timeconfig options. Theres no real reason to make this a static selection. We canadd a sysctl that allows for the dynamic selection of these algorithms at runtime, with the default value determined by the corresponding crypto libraryavailability.This comes in handy when, for example running a system in FIPS mode, where useof md5 is disallowed, but SHA1 is permitted.Note: This new sysctl has no corresponding socket option to select the cookiehmac algorithm. I chose not to implement that intentionally, as RFC 6458contains no option for this value, and I opted not to pollute the socket optionnamespace.Change notes:v2) * Updated subject to have the proper sctp prefix as per Dave M. * Replaced deafult selection options with new options that allow developers to explicitly select available hmac algs at build time as per suggestion by Vlad Y.Signed-off-by: Neil Horman CC: Vlad Yasevich CC: "David S.
