Public bug reported: Binary package hint: linux-image-2.6.27-9-generic
When opening a file for the first time in my Private folder with Emacs (compiled from CVS HEAD), the attached Oops occur. The funny thing is that if I open it with less first, the Oops will not show. My ecryptfs is running on top of reiserfs 3.6. $ uname -a Linux ubuntu 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux $ cat /proc/version_signature Ubuntu 2.6.27-9.19-generic $ dmesg: [ 4114.680276] ecryptfs_init_crypt_ctx: cryptfs: init_crypt_ctx(): Error initializing cipher [aes] [ 4114.682057] BUG: unable to handle kernel NULL pointer dereference at 00000006 [ 4114.682063] IP: [<e0e8ba81>] :ecryptfs:decrypt_scatterlist+0x41/0xf0 [ 4114.682081] *pde = 00000000 [ 4114.682086] Oops: 0000 [#1] SMP [ 4114.682091] Modules linked in: aes_i586 aes_generic ecb crypto_blkcipher ecryptfs af_packet binfmt_misc radeon drm bridge stp rfcomm bnep sco l2cap ppdev ipv6 speedstep_centrino cpufreq_powersave cpufreq_stats cpufreq_userspace cpufreq_ondemand cpufreq_conservative freq_table container wmi sbs pci_slot sbshc iptable_filter ip_tables x_tables ext3 jbd mbcache sbp2 lp loop joydev pcmcia thinkpad_acpi rfkill led_class nvram evdev snd_intel8x0 snd_ac97_codec btusb psmouse serio_raw ac97_bus battery bluetooth snd_pcm_oss snd_mixer_oss ac snd_pcm snd_seq_dummy video output nsc_ircc parport_pc parport irda crc_ccitt pcspkr ipw2100 snd_seq_oss snd_seq_midi snd_rawmidi ieee80211 ieee80211_crypt yenta_socket rsrc_nonstatic snd_seq_midi_event pcmcia_core snd_seq snd_timer snd_seq_device snd soundcore snd_page_alloc button iTCO_wdt iTCO_vendor_support intel_agp shpchp pci_hotplug agpgart reiserfs usb_storage libusual sr_mod cdrom sd_mod crc_t10dif sg ata_piix ata_generic pata_acpi libata ehci_hcd e1000 ohci1394 scsi_mod uhci_hcd ieee1394 usbcore dock thermal processor fan fbcon tileblit font bitblit softcursor fuse [ 4114.682201] [ 4114.682204] Pid: 19384, comm: emacs Not tainted (2.6.27-9-generic #1) [ 4114.682208] EIP: 0060:[<e0e8ba81>] EFLAGS: 00210246 CPU: 0 [ 4114.682218] EIP is at decrypt_scatterlist+0x41/0xf0 [ecryptfs] [ 4114.682222] EAX: fffffffe EBX: c2e848ec ECX: 00000010 EDX: c2e84938 [ 4114.682225] ESI: fffffffe EDI: c2e849a0 EBP: dfa65cb8 ESP: dfa65c8c [ 4114.682228] DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 [ 4114.682232] Process emacs (pid: 19384, ti=dfa64000 task=dd676480 task.ti=dfa64000) [ 4114.682235] Stack: 00000030 00000000 00000000 dfa65cf8 dfa65ce4 fffffffe dfa65d0c 00000200 [ 4114.682245] 00001000 00000000 00000000 dfa65d28 e0e8ca0e 00001000 dfa65d0c c01b1a42 [ 4114.682254] 00000000 00000000 c1442f5c c2e848ec c111d24c 00000000 c111d24e 00000000 [ 4114.682262] Call Trace: [ 4114.682266] [<e0e8ca0e>] ? ecryptfs_decrypt_extent+0x15e/0x200 [ecryptfs] [ 4114.682278] [<c01b1a42>] ? fsnotify_access+0x72/0x80 [ 4114.682287] [<e0e8cb71>] ? ecryptfs_decrypt_page+0xc1/0x1b0 [ecryptfs] [ 4114.682298] [<c0191756>] ? __inc_zone_state+0x16/0x80 [ 4114.682306] [<e0e8a49f>] ? ecryptfs_readpage+0xcf/0x150 [ecryptfs] [ 4114.682316] [<c0185477>] ? add_to_page_cache_lru+0x47/0x60 [ 4114.682325] [<c018cf68>] ? __do_page_cache_readahead+0x168/0x1e0 [ 4114.682331] [<c018d2d1>] ? ondemand_readahead+0xf1/0x150 [ 4114.682337] [<c018d3ed>] ? page_cache_sync_readahead+0x2d/0x40 [ 4114.682342] [<c01861f1>] ? do_generic_file_read+0x251/0x4e0 [ 4114.682348] [<c0186523>] ? generic_file_aio_read+0xa3/0x1d0 [ 4114.682353] [<c0183f80>] ? file_read_actor+0x0/0xe0 [ 4114.682359] [<e0e871a0>] ? ecryptfs_read_update_atime+0x30/0x70 [ecryptfs] [ 4114.682381] [<c01b1f19>] ? do_sync_read+0xd9/0x120 [ 4114.682387] [<c01474b0>] ? autoremove_wake_function+0x0/0x50 [ 4114.682393] [<c02353be>] ? apparmor_file_permission+0x1e/0x40 [ 4114.682401] [<c0213664>] ? security_file_permission+0x14/0x20 [ 4114.682407] [<c01b1fad>] ? rw_verify_area+0x4d/0xc0 [ 4114.682412] [<c01b26cd>] ? vfs_read+0x9d/0x110 [ 4114.682417] [<c01b1e40>] ? do_sync_read+0x0/0x120 [ 4114.682422] [<c01b2812>] ? sys_read+0x42/0x70 [ 4114.682426] [<c0103f7b>] ? sysenter_do_call+0x12/0x2f [ 4114.682433] ======================= [ 4114.682435] Code: 00 00 00 89 4d e0 8b 40 24 c7 45 f0 00 02 00 00 89 45 e8 8b 45 0c 89 45 ec 89 f8 e8 5a 1a 4f df 8b 73 24 8d 53 4c 8b 4b 14 89 f0 <ff> 56 08 85 c0 75 78 8b 45 08 c7 44 24 04 08 29 e9 e0 c7 04 24 [ 4114.682482] EIP: [<e0e8ba81>] decrypt_scatterlist+0x41/0xf0 [ecryptfs] SS:ESP 0068:dfa65c8c [ 4114.682496] ---[ end trace 85676ea06c4c15f0 ]--- ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- ecryptfs Oops https://bugs.launchpad.net/bugs/314701 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
