So I'll work on it. Committed some code that's more similar to the RFC, and it recognizes the github cookies. The code didn't turn out badly, so I don't know why I was hesitant at the time.

I get maybe a thousand of lines per minute such as: Jul 7 16:22:04 g0n kernel: grsec: (miro:U:/usr/lib64/dillo/dpi) exec of /usr/lib64/dillo/dpi/cookies/cookies.dpi (/usr/lib64/dillo/dpi/cookies/cookies.dpi ) by /usr/lib64/dillo/dpi/cookies/cookies.dpi[dpid:1362] uid/euid:1000/1000 gid/egid:1000/1000, parent /usr/bin/dpid[dpid:6224] uid/euid:1000/1000 gid/egid:1000/1000 Now, the explanation is I use: # cat /proc/sys/kernel/grsecurity/exec_logging 1 # the exec_logging functionality of the grsecurity-patched kernel.

My: ~/.dillo/cookies.txt had only that one line that I send in the message: http://lists.dillo.org/pipermail/dillo-dev/2015-July/010582.html but now it has a huge many more of them: $ ls -l ~/.dillo/cookies.txt -rw------- 1 miro miro 24868 2015-07-07 11:34 /home/miro/.dillo/cookies.txt $ $ cat ~/.dillo/cookies.txt | wc -l 108 $ , and almost all those lines are from phpbb2mysql: $ cat ~/.dillo/cookies.txt | grep -v phpbb2mysql # HTTP Cookie File # This is a generated file!

If I manage to open forums.gresecurity.net, because for some, probably related reason, I can't currently. I tried, and it was just the Stop icon with an 'x' in it going red, but wouldn't open.

Trying again: forums.gresecurity.net No. Finding it in https://duckduckgo.com/html and opening it from there: worked. Now, let me explain how it went (and I hope some of the advanced users --or maybe even spender or PaX Team-- if they are reading this, I hope it helps diagnose the problems, btwn you, devs od Dillo, and them, the grsec/PaX devs. (I will, next, try and post my dillo related configuration in a new post that I will try and open in forums.gresecurity.net and then it will be a complete report, without that post to be it is not yet.) So, let me explain how it went: The link (be it from grsecurity.net or from debian net domain, which I tried also, as I wanted to show you that I evangelize for you, in digressiona: http://forums.debian.net/viewtopic.php?f=16&t=108616&p=584160#p584160 where find: because I really like Gentoo and (Debian/Devuan?), and Dillo and Postfix, and a lot of other programs ) So [the link] begins to open, and those maybe 1000 lines per minute begin to flood my /var/log/messages, Another typical one, just like the one that I already gave closer to the start of this message of mine: Jul 7 16:47:16 g0n kernel: grsec: (miro:U:/usr/lib64/dillo/dpi) exec of /usr/lib64/dillo/dpi/cookies/cookies.dpi (/usr/lib64/dillo/dpi/cookies/cookies.dpi ) by /usr/lib64/dillo/dpi/cookies/cookies.dpi[dpid:28919] uid/euid:1000/1000 gid/egid:1000/1000, parent /usr/bin/dpid[dpid:28798] uid/euid:1000/1000 gid/egid:1000/1000 Then I, in another terminal, as root, issue: # killall dpid which for grsecurity.net page opening need be done maybe once or rarely twice if at all, but for debian.net page opening needs to be done a few times, as it keeps restarting... And, if I missed to explain something, I'll try and remember and explain in the next message. As I said, for this to be complete, I need to get a better understanding of how to sort my /etc/grsec/policy for my Dillo.

I see what the problems are with github cookies. 1. In cookiesrc, ".github.com" is for subdomains of github, and "github.com" is for that host itself, so you need a "github.com" rule. 2. I was reluctant to follow the full date parsing in RFC 6265 until I had a compelling reason, but you have brought me a compelling reason. github's cookies have expiration dates like "Sat, 07 Jul 2035 13:24:19 -0000", which appears to be legal, but dillo doesn't recognize it. So I'll work on it. (By the way, I wonder why they think their cookie should last for 20 years. Makes me feel that I haven't been wasting my time with being careful with Year 2038 overflow on 32-bit machines...)

Rewrote the FAQ entry in an effort to emphasize that it was showing what was happening at the time and isn't exactly what you're likely to see today. The hope is that people see the principle involved from the example, that sometimes it blocked things that you wanted, and sometimes it blocked things that you did not want.

Github et alia login/cookies issue

by miroslav.rovis1＠zg.ht.hr

"Something went wrong with that request. Please try again." is what I get (in bottom of the login page). The: $ cat ~/.dillo/cookiesrc DEFAULT DENY .github.com ACCEPT .devuan.org ACCEPT .gentoo.org ACCEPT .wikibooks.org ACCEPT .grsecurity.net ACCEPT $ contains them. And the: $ cat ~/.dillo/cookies.txt # HTTP Cookie File # This is a generated file! Do not edit. # [domain subdomains path secure expiry_time name value] $ is empty! I saw no errors in /var/log/messages though! But I'll try something. If it works for me, it might be useful for others, if not, maybe I get some help on it. I've always been able to login fine into forums.debian.net, forums.gentoo,org, forums.grsecurity.net and forum.sleuthkit.org (after Google stopped banning me, in the captcha that they use to register; Google, the surveillor of the world, is my distasteful enemy... Nobody should be afraid of them, lots of us Liliputians will always overcome any ugly Gullivers like the Schmoog is). --- All the above was prepared for sending yesterday, 2015-07-06. LATER. I even got (and all the conf is the same, .gitbub,com is in cookiesrc), just this morning 2015-07-07 09:35 right now, the: "Cookies must be enabled to use GitHub." when making another attemt to log into Github. But that was when I rebooted into my old: 3.19.6-hardened kernel maybe half hour ago (for unrelated reasons). And take a look at the following: This is the cookies.txt file, Only gentoo wrote in it, so far (and I accessed all those since, and esp. I took care to try the github). # HTTP Cookie File # This is a generated file! Do not edit. # [domain subdomains path secure expiry_time name value] forums.gentoo.org TRUE / TRUE 1467787565 phpbb2mysql_data_s a%3A2%3A%7Bs%3A11%3A%22autologinid%22%3Bs%3A0%3A%22%22%3Bs%3A6%3A%22userid%22%3Bs%3A6%3A%22334555%22%3B%7D Don't know if there's any secrets detrimental for me, that I'd be revealing, do modified some numbers in that forums.gentoo.org entry, just in case. I need to be on the fonts issue (but I think some of you, is it even you, Jorge, who do the development in gentoo, not sure)... I thought I'd still post this, as this might be a useful report for you, devs. OTOH, I'll post the emerge --info and more when I try the bug report on the fonts. Just: $ uname -r 4.0.7-hardened-150705 $ Could it be an issue with hardened? What I did yesterday (I began writing this message yesterday, which is all before the "LATER" mark above), is I applied paxctl-ng -m on the binaries in /usr/lib64/dillo/dpi/*/<the binary>, id est: I disabled the MPROTEXT on them. I also have a text prepared on those, hopefully I send it next. -- Miroslav Rovis Zagreb, Croatia http://www.CroatiaFidelis.hr
