Hi Kevin, it was the name used (#ifdef __Panda__) in the upstream SCTP code for using it in an Cisco proprietary product. Since I don't know if that code is still used, but they haven't contributed anything back, I think it is OK to reduce the #ifdef = complexity upstream and remove it.=20 Best regards Michael >=20 > On Sat, Jun 6, 2020 at 11:20 AM Michael Tuexen <tuexen@freebsd.org> = wrote: >>=20 >> Author: tuexen >> Date: Sat Jun 6 18:20:09 2020 >> New Revision: 361872 >> URL: https://svnweb.freebsd.org/changeset/base/361872 >>=20 >> Log: >> Non-functional changes due to cleanup (upstream removing of Panda = support) >> of the code >>=20 >> MFC after: 1 week >>=20 >> Modified: >> head/sys/netinet/sctp_constants.h >> head/sys/netinet/sctp_indata.c >> head/sys/netinet/sctp_os.h >> head/sys/netinet/sctp_output.c >> head/sys/netinet/sctp_pcb.c >> head/sys/netinet/sctp_usrreq.c >>=20 >> Modified: head/sys/netinet/sctp_constants.h >> = =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D >> --- head/sys/netinet/sctp_constants.h Sat Jun 6 17:48:55 2020 = (r361871) >> +++ head/sys/netinet/sctp_constants.h Sat Jun 6 18:20:09 2020 = (r361872) >> @@ -576,7 +576,6 @@ __FBSDID("$FreeBSD$"); >> */ >> #define SCTP_ASOC_MAX_CHUNKS_ON_QUEUE 512 >>=20 >> - >> /* >> * Basically the minimum amount of time before I do a early FR. = Making this >> * value to low will cause duplicate retransmissions. >> @@ -756,9 +755,8 @@ __FBSDID("$FreeBSD$"); >> #define SCTP_FROM_SCTP_ASCONF 0x80000000 >> #define SCTP_FROM_SCTP_OUTPUT 0x90000000 >> #define SCTP_FROM_SCTP_PEELOFF 0xa0000000 >> -#define SCTP_FROM_SCTP_PANDA 0xb0000000 >> -#define SCTP_FROM_SCTP_SYSCTL 0xc0000000 >> -#define SCTP_FROM_SCTP_CC_FUNCTIONS 0xd0000000 >> +#define SCTP_FROM_SCTP_SYSCTL 0xb0000000 >> +#define SCTP_FROM_SCTP_CC_FUNCTIONS 0xc0000000 >>=20 >> /* Location ID's */ >> #define SCTP_LOC_1 0x00000001 >>=20 >> Modified: head/sys/netinet/sctp_indata.c >> = =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D >> --- head/sys/netinet/sctp_indata.c Sat Jun 6 17:48:55 2020 = (r361871) >> +++ head/sys/netinet/sctp_indata.c Sat Jun 6 18:20:09 2020 = (r361872) >> @@ -2721,8 +2721,7 @@ sctp_process_data(struct mbuf **mm, int iphlen, = int *o >> * cluster... i.e. it is a small packet sent in and yet the = driver >> * underneath allocated a full cluster for it.
