j_vfrom KConfig: "Enables BPF JIT and removes BPF interpreter to avoid speculative execution of BPF instructions by the interpreter"01:13
j_vI think that bpf (berkeley packet filter) is used mainly for seccomp and netfilter, and I'm sure that there is more about it that I haven't read about and/or can't remember details of now01:15
j_vI know that I set this to 'Y', though I won't deny that I still could use a better understanding of the ramifications01:16
j_vwhat struck me was the "avoid speculative exucution" part01:21
jaegerI wonder if there's any reason to enable it without bpf01:26

j_vIf the "Enable bpf() system call" option isn't enabled, then it doesn't come up02:48
j_vSo, my thought is no.02:48
j_vAnd I won't deny that I need to investigate my own need (or lack there of) for bpf.02:49
nomius< j_v> what struck me was the "avoid speculative exucution" part <---- Same her, this looks like came up as part of Spectre mitigation...03:36
nomiusHas anyone tried chromium 65?04:00
jaegerNot I04:40
Worksterfrinnst, i do have llvm and clang i cn push tonight, but i still have issues compiling chromium.05:29

nomiusWorkster: fontconfig 2.13 might be causing some troubles in chromium. Looks like reverting fontconfig to 2.12.6 might help...07:13
nomiusThis looks like the problematic patch: https://cgit.freedesktop.org/fontconfig/commit/?id=9a0fcb948fe7346f6c68028b2e54ab600a2a2a6f07:14
Romsterhrmmm you might be onto something07:55
frinnstbpf is exploitable, bpf jit is a mitigation for the exploits08:27
frinnstso unless bpf is enabled its pointless08:27

chinarulezzzpedja: I'm using git versions of ports.10:08
*** randn01z has joined #crux-devel10:09
pedjayeah, I see that10:10
chinarulezzzRomster: This is principled position. I'm not hiding my identity.10:10
chinarulezzz:)10:10
chinarulezzzpedja: It's much more convenient for me to use the build date as a release version, instead of a commit hash. In the contrib repo, of course, I will not do this.10:14
pedjainteresting licence choice :)10:17
Romsterbrb making coffee10:20
pedjaI don't see any major issues with the ports, otherwise, and prtverify is mostly happy with them, so10:23

frinnstomg new sysvinit release18:07
frinnsthttp://git.savannah.nongnu.org/cgit/sysvinit.git/commit/?id=986bee63c05ad98bea77997be7dd2bfc957cfc2f looks nice. I've had problems with that18:08
jaegerlies!18:08
frinnst\o/18:09
frinnstwell, booted up again atleast.18:17
jaegerwoot, hehe18:17
nomiusRomster: Just in case, I did wrote a script to convert the chrome debian package into a crux one, but it depends on cups (I actually created a port named libcups that includes only the library used by chrome)18:26
j_vwow, ChangeLog for sysvinit-2.89 is long.18:30
j_vI've never had any issues with sysvinit being broken by borked shared libs, but in theory it could happen. Would it make sense to link sysvinit statically? (make STATIC="-static")19:06
jaeger96m12s to build rust on the ISO build system19:17
jaeger8 cores @ 2.40GHz19:18
jaegerI plan to run another 3.4 bootstrap for the latest firefox and kernel, so feel free to merge in other stuff you want to test like sysvinit :)19:25
nomiusI'm already runnign 3.4... So please let me know if there's anything else I need to rebuild besides ports updates :-)19:30
*** onodera has quit IRC20:51
frinnstbuilding 1.24.1 now anyways21:04

pedjaACTION was building gcc-fortran few days ago21:35
pedjathat was...painfully slow :)21:35
john_cephalopodaI am now building firefox after building rust for ages.21:35
john_cephalopodaAll that only because I want to open an html file of updated feeds that I generate with the suckless Atom/RSS reader sfeed.21:36
pedjaI stopped building ff ages ago,21:37
john_cephalopodaI should probably do that, too.21:38
frinnstwow. my milk carton explains encryption. It even features a cartoon computer screen with the letters "PGP" on21:39
frinnstACTION is proud21:39
pedjapics, please21:39
frinnsthttps://planet-express.se/arla-pgp.jpg21:42
pedjathat's cool. but what's the context? 'children, brush your teeth, drink milk and ENCRYPT ALL THE THINGS!'21:48
pedjawhich, as messages go, is pretty awesome, tbh :)21:49
frinnstheh pretty much. they usually try to be very informative for young kids on the back22:30
