Ahh.. Look in your directory. You did not create the sub=E2=80=99dirs or put rack.c or bbr.c into the = right places When you load the patch (which was updated Sept 17th and should be = different slightly) you will end up dropping a Makefile and bbr.c and tcp_bbr.h into the = local dir since for what every reason patch cannot figure out how to place it. You must move=20 bbr.c/tcp_bbr.h to -> sys/netinet/tcp_stacks You must create sys/modules/tcp/bbr and=20 place the make file under there (just like rack=E2=80=99s). Do that and I think you will finally have it.. not sure why patch is not = able to put the new files in the right places :0 R > On Sep 19, 2019, at 10:42 AM, vm finance <vm.finance2@gmail.com> = wrote: >=20 > Hello Randall, >=20 > I just retried it with headvm config that you had shared but still see = error while doing > "make cleandepend" >=20 > Any pointers highly appreciated. >=20 > Thanks >=20 > root@osboxes:/usr/src/sys/amd65/compile/headvm # make cleandepend=20 > [...snip...] >=20 > =3D=3D=3D> sysvipc/sysvshm (obj) > = /usr/src/sys/amd64/compile/headvm/modules/usr/src/sys/modules/sysvipc/sysv= shm created for /usr/src/sys/modules/sysvipc/sysvshm > =3D=3D=3D> tcp (obj) > =3D=3D=3D> tcp/bbr (obj) > cd: /usr/src/sys/modules/tcp/bbr: No such file or directory > *** Error code 2 >=20 > Stop. > make[2]: stopped in /usr/src/sys/modules/tcp > *** Error code 1 >=20 > Stop. > make[1]: stopped in /usr/src/sys/modules > *** Error code 1 >=20 > Stop. > make: stopped in /usr/src/sys/amd64/compile/headvm > root@osboxes:/usr/src/sys/amd64/compile/headvm #=20 >=20 >=20 > On Wed, Sep 18, 2019 at 11:08 PM vm finance <vm.finance2@gmail.com> = wrote: > Hi Randall, >=20 > I applied the patch available at:=20 > https://reviews.freebsd.org/D21582?id=3D62213 > NOTE: This raw patch seems to be exactly the same as the one I = downloaded on Sep10...hope I'm not missing anything here... >=20 > I clicked on "download raw diff" and saved it to bbr_patch.diff file = on my local machine > Step 1: Apply PATCH: > cd /usr/src/sys > patch < bbr_patch.diff > Patch was applied successfully - no errors seen there. >=20 > Step 2: Update kernel config: > cp /usr/src/sys/amd64/conf/GENERIC /usr/src/sys/amd64/conf/MYKERNEL=20 > Added three options to MYKERNEL (per ur email - I have also attached = the compile MYKERNEL file) > cd /usr/src/sys/amd64/compile/MYKERNEL > make cleandepend > =3D>This fails due to missing "bbr" under /usr/src/sys/modules/tcp/ > [pls find the attached log file for exact error] >=20 > make depend > =3D> This also fails due to missing "/usr/src/sys/modules/tcp/bbr" >=20 > STEP 3: > cd /usr/src/ > make buildkernel KERNCONF=3DMYKERNEL > This also fails due to prior errors in Step 2. >=20 > Please find MYKERNEL config file + error logs. >=20 > Many many thanks for taking time to help me through this! >=20 > PS: I did a make buildkernel without any KERNCONF=3DMYKERNEL, and that = successfully finished. >=20 >=20 >=20 > On Thu, Sep 19, 2019 at 12:19 PM Randall Stewart <rrs@netflix.com> = wrote: > You can look in the config I sent.. but here is what > I have added to enable BBR and Rack to be built > ***** > makeoptions WITH_EXTRA_TCP_STACKS=3D1 > options TCPHPTS=20 > options RATELIMIT > ****** >=20 > So you should > 1) Apply the current patch in phabricator > 2) edit your config and add the above three lines > 3) go to the src dir and type > make buildkernel KERNCONF=3Dmyconf >=20 > That should build and get you a kernel that will include bbr and rack. = You will > need to, after it boots up type >=20 > kldload tcp_bbr >=20 > or >=20 > kldload tcp_rack >=20 > To get the modules loaded >=20 > R >=20 >=20 >=20 > > On Sep 18, 2019, at 2:31 PM, vm finance <vm.finance2@gmail.com> = wrote: > >=20 > > Hi Randall, Michael, > >=20 > > Build is done successfully.
