treewide: replace or remove redundant def_bool in Kconfig files'def_bool X' is a shorthand for 'bool' plus 'default X'.'def_bool' is redundant where 'bool' is already present, so 'def_bool X'can be replaced with 'default X', or removed if X is 'n'.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/net/dccp/ccids/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/dccp/ccids/Kconfig

89858ad1 - dccp ccid-3: use per-route RTO or TCP RTO as fallback

Sun, 29 Aug 2010 19:23:14 +0000

dccp ccid-3: use per-route RTO or TCP RTO as fallbackThis makes RTAX_RTO_MIN also available to CCID-3, replacing the compile-timeRTO lower bound with a per-route tunable value.The original Kconfig option solved the problem that a very low RTT (in theorder of HZ) can trigger too frequent and unnecessary reductions of thesending rate.This tunable does not affect the initial RTO value of 2 seconds specified inRFC 5348, section 4.2 and Appendix B. But like the hardcoded Kconfig value,it allows to adapt to network conditions.The same effect as the original Kconfig option of 100ms is now achieved by> ip route replace to unicast 192.168.0.0/24 rto_min 100j dev eth0(assuming HZ=1000).Signed-off-by: Gerrit Renker Signed-off-by: David S.

ddebc973 - dccp: Lockless integration of CCID congestion-control plugins

Mon, 05 Jan 2009 05:42:53 +0000

dccp: Lockless integration of CCID congestion-control pluginsBased on Arnaldo's earlier patch, this patch integrates the standardisedCCID congestion control plugins (CCID-2 and CCID-3) of DCCP with dccp.ko: * enables a faster connection path by eliminating the need to always go through the CCID registration lock; * updates the implementation to use only a single array whose size equals the number of configured CCIDs instead of the maximum (256); * since the CCIDs are now fixed array elements, synchronization is no longer needed, simplifying use and implementation.CCID-2 is suggested as minimum for a basic DCCP implementation (RFC 4340, 10);CCID-3 is a standards-track CCID supported by RFC 4342 and RFC 5348.Signed-off-by: Gerrit Renker Signed-off-by: David S.

c8f41d50 - dccp ccid-3: Measuring the packet size s with regard to rfc3448bis-06

Thu, 04 Sep 2008 05:30:19 +0000

dccp ccid-3: Measuring the packet size s with regard to rfc3448bis-06rfc3448bis allows three different ways of tracking the packet size `s': 1. using the MSS/MPS (at initialisation, 4.2, and in 4.1 (1)); 2. using the average of `s' (in 4.1); 3. using the maximum of `s' (in 4.2).Instead of hard-coding a single interpretation of rfc3448bis, this implementsa choice of all three alternatives and suggests the first as default, since itis the option which is most consistent with other parts of the specification.The patch further deprecates the update of t_ipi whenever `s' changes. Thegains of doing this are only small since a change of s takes effect at thenext instant X is updated: * when the next feedback comes in (within one RTT or less); * when the nofeedback timer expires (within at most 4 RTTs). Further, there are complications caused by updating t_ipi whenever s changes: * if t_ipi had previously been updated to effect oscillation prevention (4.5), then it is impossible to make the same adjustment to t_ipi again, thus counter-acting the algorithm; * s may be updated any time and a modification of t_ipi depends on the current state (e.g. no oscillation prevention is done in the absence of feedback); * in rev-06 of rfc3448bis, there are more possible cases, depending on whether the sender is in slow-start (t_ipi <= R/W_init), or in congestion-avoidance, limited by X_recv or the throughput equation (t_ipi <= t_mbi).Thus there are side effects of always updating t_ipi as s changes. These may notbe desirable. The only case I can think of where such an update makes sense isto recompute X_calc when p > 0 and when s changes (not done by this patch).Signed-off-by: Gerrit Renker List of files: /linux-6.15/net/dccp/ccids/Kconfig

891e4d8a - dccp ccid-3: Tidy up CCID-Kconfig dependencies

Thu, 04 Sep 2008 05:30:19 +0000

dccp ccid-3: Tidy up CCID-Kconfig dependenciesThe per-CCID menu has several dependencies on EXPERIMENTAL. These are redundant,since net/dccp/ccids/Kconfig is sourced by net/dccp/Kconfig and since thelatter menu in turn asserts a dependency on EXPERIMENTAL.The patch removes the redundant dependencies as well as the repeated referencewithin the sub-menu.Further changes:----------------Two single dependencies on CCID-3 are replaced with a single enclosing `if'.

5a577b48 - dccp ccid-2: Remove old infrastructure

Thu, 04 Sep 2008 05:30:19 +0000

dccp ccid-2: Remove old infrastructureThis removes * functions for which updates have been provided in the preceding patches and * the @av_vec_len field - it is no longer necessary since the buffer length is now always computed dynamically; * conditional debugging code (CONFIG_IP_DCCP_ACKVEC).The reason for removing the conditional debugging code is that Ack Vectors are an almost inevitable necessity - RFC 4341 says that for CCID-2, Ack Vectors mustbe used. Furthermore, the code would be only interesting for coding - after some extensive testing with this patch set, having the debug code around is no longerof real help.Signed-off-by: Gerrit Renker List of files: /linux-6.15/net/dccp/ccids/Kconfig

e333b3ed - [DCCP]: Promote CCID2 as default CCID

Wed, 21 Nov 2007 12:09:56 +0000

[DCCP]: Promote CCID2 as default CCIDThis patch addresses the following problems: 1. DCCP relies for its proper functioning on having at least one CCID module enabled (as in TCP plugable congestion control). Currently it is possible to disable both CCIDs and thus leave the DCCP module in a compiled, but entirely non-functional state: no sockets can be created when no CCID is available. Furthermore, the protocol is (again like TCP) not intended to be used without CCIDs. Last, a non-empty CCID list is needed for doing CCID feature negotiation. 2. Internally the default CCID that is advertised by the Linux host is set to CCID2 (DCCPF_INITIAL_CCID in include/linux/dccp.h). Disabling CCID2 in the Kconfig menu without changing the defaults leads to a failure `module not found' when trying to load the dccp module (which internally tries to load the default CCID). 3. The specification (RFC 4340, sec. 10) treats CCID2 somewhat like a `minimum common denominator'; the specification says that: * "New connections start with CCID 2 for both endpoints" * "A DCCP implementation intended for general use, such as an implementation in a general-purpose operating system kernel, SHOULD implement at least CCID 2. The intent is to make CCID 2 broadly available for interoperability [...]" Providing CCID2 as minimum-required CCID (like Reno/Cubic in TCP) thus seems reasonable.Hence this patch automatically selects CCID2 when DCCP is enabled. Documentation also added.Discussions with Ian McDonald on this subject are gratefully acknowledged.Signed-off-by: Gerrit Renker Signed-off-by: Ian McDonald Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

8a508ac2 - [DCCP]: Use higher RTO default for CCID3

Sun, 03 Dec 2006 16:50:23 +0000

[DCCP]: Use higher RTO default for CCID3The TFRC nofeedback timer normally expires after the maximum of 4RTTs and twice the current send interval (RFC 3448, 4.3). On LANswith a small RTT this can mean a high processing load and reducedperformance, since then the nofeedback timer is triggered veryfrequently.This patch provides a configuration option to set the bound for thenofeedback timer, using as default 100 milliseconds.By setting the configuration option to 0, strict RFC 3448 behaviourcan be enforced for the nofeedback timer.Signed-off-by: Gerrit Renker Signed-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/net/dccp/ccids/Kconfig
