[Bug 1536487] Re: Unable to migrate pc-i440fx-2.4 KVM guest from QEMU 2.5.0 to QEMU 2.4.1
> Especially I found that the "created on Trusty, migrated to xenial > (works), but later migrated back to trusty (fails)" seems affected by > it as well. The first migration of the t->x->t sequence does not really matter (if anything it could introduce _more_ bugs!), so if x->t is not supported then neither is t->x->t. The upstream QEMU project doesn't have the manpower to test and support backwards migration. We try not to break it, and in this case there was an easy fix and we suggest that Canonical backports it. However, in general it's not guaranteed to work. The fix is commit e6915b5f3a874a467a9a65f7ec1d6ef8d251a51a. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1536487 Title: Unable to migrate pc-i440fx-2.4 KVM guest from QEMU 2.5.0 to QEMU 2.4.1 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1536487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1155403] Re: virtio cdrom detected as hard disk
It seems the installer does not consider virtio devices when doing its search. That's another bug in the installer then. it seems a bit wasteful to go through a layer of scsi emulation. Indeed treating the virtio disk similarly to installation from a USB stick is better, but SCSI emulation is actually a very good way to not reinvent the wheel. CD-ROM/DVD-ROM media need a lot of magic (such as subdivision of the medium into tracks, different media formats, etc.) and emulating those in virtio-blk would be even more wasteful. Shouldn't qemu at least warn you that the media=argument does nothing on virtio devices instead of silently ignoring it? Yes, that's a legitimate request. Or better yet, shouldn't it automatically use virtio-scsi instead? No, virtio-scsi is relatively new and not all distros have picked it up yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155403 Title: virtio cdrom detected as hard disk To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1155403/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The media argument seems a perfectly natural way to select between the two. Then how do you distinguish between a virtio-scsi and a virtio-blk hard disk?

[Bug 521523] Re: severe ecryptfs corruption
Any git repository I use heavily (mostly kernel, Xen and qemu in my case, but it is not relevant I think) will corrupt at least once a day, as proved from the fact that I just reproduced it. :) Probably interactive rebases and switching branches help. However, I don't know how to make the error occur. I created the repositories in a non-ecryptfs dir and then rsynced a lot of files to ecryptfs -- however I don't believe this is related to the bug.

[Bug 490005] Re: ecryptfs_readpage: Error decrypting page
I am seeing these messages whenever I have two processes reading the same file. Note that write access is not necessary. The simplest way to reproduce it is git grep abczzz git grep abczzz but this is probably because git uses multiple threads, rather than because the bug is related to git. In fact, I reproduced it in places where I have not even moved the HEAD of this repository since I copied it from an unencrypted directory to an ecryptfs one. Another way to reproduce it for me (but much less consistently) is: (find . -type f | xargs md5sum /dev/null) find . -type f | xargs md5sum /dev/null which gives occasional Input/Output errors. In some cases (and especially with git grep) instead the program sees an empty file (confirmed with strace) which shows as error: 'Documentation/HOWTO': short read Success error: 'Documentation/arm/tcm.txt': short read Success error: 'Documentation/braille-console.txt': short read Success At the same time, the dreaded messages appear in /var/log/messages Dec 7 16:55:54 yakj kernel: [32510.145170] ecryptfs_readpage: Error decrypting page; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145180] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145182] ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145184] ecryptfs_readpage: Error decrypting page; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145198] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145231] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145235] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145245] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145285] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:55:54 yakj kernel: [32510.145320] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:59:56 yakj kernel: [32752.032531] ecryptfs_read_and_validate_header_region: Error reading header region; rc = [-4] Dec 7 16:59:56 yakj kernel: [32752.032550] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved.

[Bug 150920] kernel overwrites MAP_PRIVATE mmap
Public bug reported: This is a kernel bug. I could reproduce it with 2.6.20 and 2.6.22 (tested with i386 and x86-64). 1) Download http://www.inf.unisi.ch/phd/bonzini/smalltalk-2.95d.tar.gz 2) Compile it with ./configure make CFLAGS=-g (the cflags is only for easier debuggability). 3) Run ./gst 4) Type ObjectMemory snapshot It crashes. To reproduce again: 5) Run rm gst.im; make gst.im 6) Go to step 4. The code that crashes is in save.c; it dereferences a NULL pointer: Program received signal SIGBUS, Bus error. 0x08083bf3 in make_oop_table_to_be_saved (header=0xbff29934) at save.c:345 345 int numPointers = NUM_OOPS (oop-object); (gdb) p oop-object-objClass $1 = (OOP) 0x0 However, going on in the debugging session, you can see that the memory is zeroed *by the kernel*: (gdb) p oop-object-objClass $2 = (OOP *) 0xb7cb8784 We set up a breakpoint a little earlier: (gdb) b 279 Breakpoint 1 at 0x8083a5d: file save.c, line 279. (gdb) shell rm gst.im; make gst.im (gdb) run Starting program: /home/bonzinip/smalltalk-2.95d/gst GNU Smalltalk ready st ObjectMemory snapshot Global garbage collection... done Breakpoint 1, _gst_save_to_file ( fileName=0x812a118 /home/bonzinip/smalltalk-2.95d/gst.im) at save.c:279 279 ftruncate (imageFd, 0); Now we set a watchpoint on the location that triggered the NULL access: (gdb) set can-use-hw-watchpoints 0 (gdb) watch *$2 Watchpoint 2: *$2 (gdb) n Watchpoint 2: *$2 Old value = (OOP) 0x126 New value = (OOP) 0x0 0xb7ee9438 in ftruncate64 () from /lib/libc.so.6 From a disassembly, you can see that it was zeroed by the kernel: (gdb) disass 0xb7ee9431 0xb7ee94ec 0xb7ee9431 ftruncate64+49:mov$0xc2,%eax 0xb7ee9436 ftruncate64+54:int$0x80 --- 0xb7ee9438 ftruncate64+56:xchg %edi,%ebx 0xb7ee943a ftruncate64+58:mov%eax,%esi I believe the reason is a bad interaction between the private mmap established in save.c: buf = mmap (NULL, file_size, PROT_READ, MAP_PRIVATE, imageFd, 0); and truncating the inode on which the mmap was done. Indeed, if the gst.im file is unlinked before opening it, the bug disappears. You can try this from the Smalltalk interpreter, without patching the source code: $ ./gst GNU Smalltalk ready st (File name: 'gst.im') remove a RealFileHandler st ObjectMemory snapshot Global garbage collection... done ObjectMemory st (no bus error anymore). I hope this long explanation is understandable! ** Affects: ubuntu Importance: Undecided Status: New -- kernel overwrites MAP_PRIVATE mmap https://bugs.launchpad.net/bugs/150920 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
