Bug ID: 216265 Summary: [patch] [mppc] invalid KASSERT prevent building kernel with NETGRAPH_MPPC_COMPRESSION and INVARIANTS Product: Base System Version: 11.0-STABLE Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: po...@grosbein.net Keywords: patch Created attachment 179079 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=179079&action=edit unbreak debugging kernel build Since 11.0-RELEASE, FreeBSD includes implementation of MMPC. Build of kernel configuration containing both of NETGRAPH_MPPC_COMPRESSION and INVARIANTS fails: --- ng_mppc.o --- /home/src/sys/netgraph/ng_mppc.c:546:18: error: use of undeclared identifier 'MPPC_INVALID' KASSERT(rtn != MPPC_INVALID, ("%s: invalid", __func__)); According to http://media.digikey.com/pdf/Data%20Sheets/EXAR%20PDFs/MPPC-C.pdf return value MPPC_INVALID (zero) for "rtn" variable was supposed to denote invalid values for arguments srcCnt, dstCnt or flags passed to function MPPC_Compress(). Our implementation in sys/net/mppcc.c does not perform such validity checks and never returns zero value, so this KASSERT should be removed. Also, /* XXX NETGRAPH_MPPC_COMPRESSION isn't functional yet */ comment in the same file and some others are not valid anymore. This includes sys/conf/NOTES and sys/conf/options. Attached patch fixes this. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
