From 5be255c28b24944b530bb8f91e6bde2e66992c2a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 1 Sep 2015 13:45:49 +0000 Subject: [PATCH] Add more TCP_* values to netinet/tcp.h. This patch adds move TCP_* values to sysdeps/gnu/netinet/tcp.h to bring it up to date with Linux 4.2. TCP_SAVE_SYN and TCP_SAVED_SYN are new in 4.2, TCP_NOTSENT_LOWAT and TCP_CC_INFO are older (Szabolcs previously noted in that this header was out of date in glibc). Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * sysdeps/gnu/netinet/tcp.h (TCP_NOTSENT_LOWAT): New macro. (TCP_CC_INFO): Likewise. (TCP_SAVE_SYN): Likewise. (TCP_SAVED_SYN): Likewise. --- ChangeLog | 7 +++++++ sysdeps/gnu/netinet/tcp.h | 8 ++++++++ 2 files changed, 15 insertions(+) diff --git a/ChangeLog b/ChangeLog index eafb44a..cb37c5d 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2015-09-01 Joseph Myers + + * sysdeps/gnu/netinet/tcp.h (TCP_NOTSENT_LOWAT): New macro. + (TCP_CC_INFO): Likewise. + (TCP_SAVE_SYN): Likewise. + (TCP_SAVED_SYN): Likewise. + 2015-08-31 Brett Neumeier [BZ #18870] diff --git a/sysdeps/gnu/netinet/tcp.h b/sysdeps/gnu/netinet/tcp.h index f6602ec..3918bca 100644 --- a/sysdeps/gnu/netinet/tcp.h +++ b/sysdeps/gnu/netinet/tcp.h @@ -61,6 +61,14 @@ #define TCP_REPAIR_OPTIONS 22 /* Repair TCP connection options */ #define TCP_FASTOPEN 23 /* Enable FastOpen on listeners */ #define TCP_TIMESTAMP 24 /* TCP time stamp */ +#define TCP_NOTSENT_LOWAT 25 /* Limit number of unsent bytes in + write queue. */ +#define TCP_CC_INFO 26 /* Get Congestion Control + (optional) info. */ +#define TCP_SAVE_SYN 27 /* Record SYN headers for new + connections. */ +#define TCP_SAVED_SYN 28 /* Get SYN headers recorded for + connection. */ #ifdef __USE_MISC # include -- 2.7.4
