Hi! as you can read in this new bug report that I submitted:
GNU debugger employed via Postfix crashed PaX hardened kernel https://bugs.gentoo.org/show_bug.cgi?id=541104 also: GNU debugger checking for PaX and refusing to work with it https://forums.gentoo.org/viewtopic-t-1011162.html and: PAX terminating task on /usr/bin/gdb http://forums.grsecurity.net/viewtopic.php?f=3&t=4137 In short, from: https://541104.bugs.gentoo.org/attachment.cgi?id=397334 Feb 23 08:43:51 gbn kernel: [30489.762828] grsec: bruteforce prevention initiated for the next 30 minutes or until service restarted, stalling each fork 30 seconds. Please investigate the crash report for /usr/bin/gdb[gdb:14515] uid/euid:0/0 gid/egid:0/0, parent /usr/bin/gdb[gdb:14507] uid/euid:0/0 gid/egid:0/0 but, if Postfix is configured correctly, mail is still sent... but the scare is ugly... Surely, the gdb on such kernel does no work at all, other than the scare on the poor user. I think it would be a good thing to post a line that reflects this issue, and warns Grsec-hardened users of it, in the: http://www.postfix.org/DEBUG_README.html Cheers!
