[Bug 999869] [NEW] vsftpd allows local users to log in even if local_enable in not set
Public bug reported: I use almost vanilla /etc/vsftpd.conf file. I am not able to log-in with a system user tuser from Debian Squeeze as expected. But if I use psftp from Putty in Windows, vsftpd will allow me to log-in, even if local_enable is commented out.

[Bug 1313450] Re: Unable to start vsftpd on Ubuntu 14.04 (Amazon/EC2) with default configuration
I'm also having the exact same issue running vsftpd on Ubuntu 14.04 in an Amazon/EC2 instance. Adding seccomp_sandbox=NO does not fix the problem for me either. Upgraded to vsftpd 3.0.2-1ubuntu2.14.04.1 that was just released on 2014-05-05 but this does not fix the issue. here the message in dmesg after to 500 OOPS: munmap: [25101608.375027] BUG: Bad page map in process vsftpd pte:8965 pmd:4fda0067 [25101608.375047] page:ea00 count:-24 mapcount:-24 mapping: (null) index:0x0 [25101608.375055] page flags: 0x14(referenced|dirty) [25101608.375065] addr:7f868625c000 vm_flags:08100071 anon_vma:880028e087c0 mapping: (null) index:7f868625c [25101608.375076] CPU: 0 PID: 4509 Comm: vsftpd Tainted: GF B 3.13.0-24-generic #46-Ubuntu [25101608.375079] 880003674540 88002a1e3c70 81715a64 7f868625c000 [25101608.375083] 88002a1e3cb8 81174183 80079e60d965 0007f868625c [25101608.375086] 88004fda02e0 ea00 7f868625c000 7f868625d000 [25101608.375089] Call Trace: [25101608.375100] [81715a64] dump_stack+0x45/0x56 [25101608.375107] [81174183] print_bad_pte+0x1a3/0x250 [25101608.375111] [81175b67] unmap_page_range+0x717/0x7f0 [25101608.375114] [81175cc1] unmap_single_vma+0x81/0xf0 [25101608.375117] [81176d39] unmap_vmas+0x49/0x90 [25101608.375123] [8117feec] exit_mmap+0x9c/0x170 [25101608.375128] [8106482c] mmput+0x5c/0x120 [25101608.375133] [81069bbc] do_exit+0x26c/0xa50 [25101608.375138] [8109dd84] ? vtime_account_user+0x54/0x60 [25101608.375144] [8114d52f] ? context_tracking_user_exit+0x4f/0xc0 [25101608.375148] [8106a41f] do_group_exit+0x3f/0xa0 [25101608.375152] [8106a494] SyS_exit_group+0x14/0x20 [25101608.375158] [8172663f] tracesys+0xe1/0xe6 [25101608.375264] BUG: Bad rss-counter state mm:88000352d180 idx:0 val:-1 [25101608.375274] BUG: Bad rss-counter state mm:88000352d180 idx:1 val:1 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vsftpd in Ubuntu. https://bugs.launchpad.net/bugs/1313450 Title: Unable to start vsftpd on Ubuntu 14.04 (Amazon/EC2) with default configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vsftpd/+bug/1313450/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1313450] Re: Unable to start vsftpd on Ubuntu 14.04 (Amazon/EC2) with default configuration
After doing a little more investigation, it looks like there are other distributions that are having problems with vsftpd running on AWS EC2 instances. It sounds like it may be related to a kernel bug that affect Xen paravirtualized hosts. http://www.gossamer- threads.com/lists/linux/kernel/1854156?search_string=%5BBISECTED%5D%20Linux%203.12.7%20introduces%20page%20map%20handling%20regression;#1854156 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vsftpd in Ubuntu. https://bugs.launchpad.net/bugs/1313450 Title: Unable to start vsftpd on Ubuntu 14.04 (Amazon/EC2) with default configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vsftpd/+bug/1313450/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
