Author: bapt Date: Sat May 27 10:50:35 2017 New Revision: 318982 URL: https://svnweb.freebsd.org/changeset/base/318982 Log: Pass a "FREEBSD" user-class in PXE dhcp request rfc3004 allows to pass multiple user classes on dhcp requests this is used by dhcp servers to differentiate the caller if needed. As an example with isc dhcp server it will be possible to make options only for the FreeBSD loaders: if exists user-class and option user-class = "FREEBSD" { option root-path "tftp://192.168.42.1/FreeBSD; } Reviewed by: tsoome Differential Revision: https://reviews.freebsd.org/D10951 Modified: head/lib/libstand/bootp.c head/lib/libstand/bootp.h Modified: head/lib/libstand/bootp.c ============================================================================== --- head/lib/libstand/bootp.c Sat May 27 08:30:32 2017 (r318981) +++ head/lib/libstand/bootp.c Sat May 27 10:50:35 2017 (r318982) @@ -146,16 +146,20 @@ bootp(int sock, int flag) bp->bp_vend[7] = TAG_CLASSID; bp->bp_vend[8] = 9; bcopy("PXEClient", &bp->bp_vend[9], 9); - bp->bp_vend[18] = TAG_PARAM_REQ; - bp->bp_vend[19] = 7; - bp->bp_vend[20] = TAG_ROOTPATH; - bp->bp_vend[21] = TAG_HOSTNAME; - bp->bp_vend[22] = TAG_SWAPSERVER; - bp->bp_vend[23] = TAG_GATEWAY; - bp->bp_vend[24] = TAG_SUBNET_MASK; - bp->bp_vend[25] = TAG_INTF_MTU; - bp->bp_vend[26] = TAG_SERVERID; - bp->bp_vend[27] = TAG_END; + bp->bp_vend[18] = TAG_USER_CLASS; + bp->bp_vend[19] = 8; + bp->bp_vend[20] = 7; + bcopy("FREEBSD", &bp->bp_vend[21], 7); + bp->bp_vend[28] = TAG_PARAM_REQ; + bp->bp_vend[29] = 7; + bp->bp_vend[30] = TAG_ROOTPATH; + bp->bp_vend[31] = TAG_HOSTNAME; + bp->bp_vend[32] = TAG_SWAPSERVER; + bp->bp_vend[33] = TAG_GATEWAY; + bp->bp_vend[34] = TAG_SUBNET_MASK; + bp->bp_vend[35] = TAG_INTF_MTU; + bp->bp_vend[36] = TAG_SERVERID; + bp->bp_vend[37] = TAG_END; } else bp->bp_vend[7] = TAG_END; #else Modified: head/lib/libstand/bootp.h ============================================================================== --- head/lib/libstand/bootp.h Sat May 27 08:30:32 2017 (r318981) +++ head/lib/libstand/bootp.h Sat May 27 10:50:35 2017 (r318982) @@ -108,6 +108,7 @@ struct bootp { #define TAG_T2 ((unsigned char) 59) #define TAG_CLASSID ((unsigned char) 60) #define TAG_CLIENTID ((unsigned char) 61) +#define TAG_USER_CLASS ((unsigned char) 77) #endif #define TAG_END ((unsigned char) 255)
