[Bug 1823917] Re: Can't set Chromium as the default browser when BROWSER variable is defined

[Walter Lapchynski]

** Description changed:

- Every time I launch the browser it suggests to be set as the default but if I 
click on that button nothing will change: I'll get the suggestion the next time 
I open Chromium, even if I reboot.
- Changing the default browser on configuration panel didn't solve the issue
+ STEPS TO REPRODUCE
+  1. Install firefox
+  2. Set `BROWSER=firefox`
+  3. Open firefox and make sure it is the default browser
+  4. Install chromium-browser
+  5. Open chromium-browser and set it as the default browser
+  6. Click on a link or use `xdg-open URL`
  
- Lubuntu 19.10 beta on Athlon 64x2 5200+
+ EXPECTED RESULTS
+ Link opens in chromium-browser
+ 
+ ACTUAL RESULTS
+ Link opens in firefox instead. Running chromium-browser from the terminal, 
when trying to change the default browser, the error "xdg-settings: $BROWSER is 
set and can't be changed with xdg-settings" appears. BROWSER, xdg-setting's 
default-web-browser, and xdg-mime's default for text/html remain unchanged. 
It's not possible to set the value of default-web-browser when the BROWSER 
variable is set. Yet, when making firefox default, the end result is that 
BROWSER is still set and default-web-browser and the default for text/html has 
changed.

[Bug 1823917] Re: Can't set Chromium as the default browser

[Walter Lapchynski]

> xdg-settings: $BROWSER is set and can't be changed with xdg-settings

That's some telling info right there.

Some things to note:

 * In lxqt-config-session, in both Default Applications and Environment
(Advanced) there is an option to set the BROWSER variable. It is set to
firefox by default. It will come back if it is deleted (possibly a bug).
Unlike TERM or EDITOR, which are part of the UNIX standard
(http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08_01),
BROWSER is not always recognized by applications.

 * There is a Freedesktop Specification for MIME types
(https://www.freedesktop.org/wiki/Specifications/mime-apps-spec/) that
lxqt-config-file-associations interacts with. The xdg-utils (XDG = X
Desktop Group, the former name of Freedesktop) tools interact with this.
You can use them to find out which is your default browser via `xdg-mime
query default text/html`. Similarly, `xdg-open` determines the MIME type
of the argument it is given and passes it to the associated application.

 * There is also update-alternatives which allows you to assign
different definitions of various types of generic programs. For example,
you could easily select from different definitions for x-www-browser. I
mention this for completeness, but it's not particularly relevant.

Now to prove this is not an issue with LXQt, consider this scenario:

 1. Load Lubuntu, which has firefox installed by default
 2. Install Opera
 3. Note that `echo $BROWSER` returns "firefox"
 4. Note that `xdg-mime query default text/html` returns "firefox.desktop"
 5. Note that `xdg-settings get default-web-browser` returns "firefox.desktop"
 6. Note `xdg-open http://ubuntu.com` opens in firefox
 7. Open qterminal and `echo 'http://ubuntu.com'`
 8. Note that holding down Ctrl and clicking on the URL opens it up in firefox
 9. Open up Opera and set it as the default browser
10. Note that `echo $BROWSER` returns "firefox"
11. Note that `xdg-mime query default text/html` returns "opera.desktop"
12. Note that `xdg-settings get default-web-browser` returns "opera.desktop"
13. Note `xdg-open http://ubuntu.com` opens in opera
14. Open qterminal and `echo 'http://ubuntu.com'`
15. Note that holding down Ctrl and clicking on the URL opens it up in opera

So why the problem with chromium-browser? Let's get back to that quote:

> xdg-settings: $BROWSER is set and can't be changed with xdg-settings

When you try to make chromium-browser default, it sees the BROWSER
variable and just gives up, whereas Opera (and Firefox) ignores it and
actually sets it. This error is actually from xdg-settings. It won't set
default-web-browser while BROWSER exists. Yet, somehow firefox and opera
both seem to deal with this. Therefore, I would call this chromium-
browser's fault.

[Bug 684878] Re: Compile errors when including liblivemedia headers

[Gregory Fong]

Not a bug in Ubuntu 14.04 at least (I can't speak for earlier versions).
The package works fine, but usage is not obvious.  The include paths and
library order should be retrieved using pkgconfig.  On an x86_64 system,
the pkgconfig file itself will be in /usr/lib/x86_64-linux-
gnu/pkgconfig/live555.pc .

Library path can be retrieved:

$ pkg-config --libs live555
-lliveMedia -lgroupsock -lBasicUsageEnvironment -lUsageEnvironment


Include flags can be retrieved:

$ pkg-config --cflags-only-I live555
-I/usr/include/liveMedia -I/usr/include/groupsock 
-I/usr/include/BasicUsageEnvironment -I/usr/include/UsageEnvironment

- The "fanotify07" and "fanotify08" from the LTP syscall tests has failed
- on a testing node with Trusty kernel installed.
+ BugLink: https://bugs.launchpad.net/bugs/1775165
+ 
+ [Impact]
+ 
+ When userspace tasks which are processing fanotify permission events act 
+ incorrectly, the fsnotify_mark_srcu SRCU is held indefinitely which causes
+ the whole notification subsystem to hang. 
+ 
+ This has been seen in production, and it can also be seen when running the 
+ Linux Test Project testsuite, specifically fanotify07. 
+ 
+ [Fix]
+ 
+ Instead of holding the SRCU lock while waiting for userspace to respond, 
+ which may never happen, or not in the order we are expecting, we drop the 
+ fsnotify_mark_srcu SRCU lock before waiting for userspace response, and then 
+ reacquire the lock again when userspace responds.
+ 
+ The fixes are from a series of upstream commits:

[Bug 1824050] Re: access.W_OK yields -1 EACCES (permission denied) on NFS mountpoints

** Tags added: apport-collected xenial

** Description changed:

  When upgrading from xenial kernel (4.4.0-145) to linux-image-generic-
  hwe-16.04 (4.15.0-47) I am no longer able to run an application that
  checks it's data directory for write access/path traversal when that
  directory is an NFS share. This works on 4.4 and 3.13 kernels that I
  tested with but fails on 4.15. I'm using NFSv3 and have seen the
  behavior with both a synology NAS as the nfs-server as well as my xenial
  desktop as the nfs-server.
  
  To reproduce:
  0.) Boot test machine with kernel 4.15.0-47
  1.) set up a NFS export on another machine (nfs-server)
  /etc/exports:
  /srv/nfstest   192.168.100.100(rw,sync,no_subtree_check)
  
  2.) mount the NFS share on the test machine and give a non-root user
  ownership of the mount, in my case I have a user: aptly, with
  home=/var/lib/aptly, and I mounted the NFS at /var/lib/aptly/test.
  aptly:aptly owns /var/lib/aptly/test.
  
  /etc/fstab:
  192.168.100.101:/srv/nfstest/var/lib/aptly/test  nfs rw,mountvers=3
  
  
  3.) attempt to call access.W_OK on the mount as the non-root user `strace 
./testaccess.py`
  stderr:
  ...
  access("/var/lib/aptly/test", W_OK) = -1 EACCES (Permission denied)
  ...
  stdout:
  ('Writeable:', False)
  ('user r,e,s', (5062, 5062, 5062))
  ('group r,e,s', (5062, 5062, 5062))
  posix.stat_result(st_mode=16895, st_ino=101188113, st_dev=48, st_nlink=3, 
st_uid=5062, st_gid=5062, st_size=4096, st_atime=1554858490, 
st_mtime=1554858633, st_ctime=1554858633)
  
  testaccess.py:
  #!/usr/bin/python
  
  import os
  import sys
  from pprint import pprint
  directory = '/var/lib/aptly/test'
  
  if __name__ == "__main__":
writeable = os.access(directory, os.W_OK)
print("Writeable:", writeable)
print("user r,e,s", os.getresuid())
print("group r,e,s", os.getresgid())
pprint(os.stat(directory))

qt本身机制决定无法去掉这个任务栏窗口，去掉的话右键点击托盘的事件会有各种问题，或者点不开。取舍之下采用了这种方案。

[Bug 1822230] Re: lubuntu 19.04 install dual screen; login user/password boxes on both displays allowing password entry

[Chris Guiver]

** Description changed:

  Lubuntu 19.04 (x86_64) QA-Test install
  
  dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd
  5000/6000/7350/8350)
  
  On first boot, i expected to see (on either display) a single login box
  for username/password. Instead I got a box on each display (as if
  mirrored) but noted the password was only appearing as dots on one
  screen.
  
  With experimentation, I can enter different passwords on each display -
  if I press  whilst inside the valid-password box I get logged in,
  if I press  on an invalid password screen (with valid password on
  the other screen) I get login failed correctly. As such I don't see how
  this could be miss-used, but it is a little confusing/distracting (at
  first), but minor.
  
  After login, if I logout I get the same two user/boxes allowing
  different entry in each. No change after reboot.
  
  My displays are differently aligned to the default; but this occurred on
  reboot before any adjustments were made to displays (to match my having
  one tilted-left so portrait mode etc)
  
  -- Addition 2019-04-06:   Is this a bad thing?   or a feature
  It creates no real issue; and I couldn't see how to miss-use it.  My primary 
box (d960 with multiple DEs) didn't use `sddm` so I  I switched to using `sddm` 
and I love it.  As I often turn one display off, it's a huge plus. 
- 
+ -- Further Addition 2019-04-10
+ I just installed openSUSE Tumbleweed over a Leap install that went bad weeks 
back, and noted it did exactly the same thing.  A `zypper info sddm` shows 
version 0.18.0-7.1  (this is not unique to Lubuntu's sddm)

[Bug 1820676] Re: Something has gone seriously wrong: import_mok_state0 failed

[Seth Arnold]

Thanks for fixing up the missing /EFI/BOOT/mmx64.efi.

With the disco beta image I was able to re-enable the secure boot
setting in my bios. I'll try to fiddle around with the installer and try
to spot if the 'cancel' button doesn't undo pending changes. (But I'm
not sure how to test that.)

Thanks

[Bug 1824050] [NEW] access.W_OK yields -1 EACCES (permission denied) on NFS mountpoints

[Ryan Stark]

Public bug reported:

When upgrading from xenial kernel (4.4.0-145) to linux-image-generic-
hwe-16.04 (4.15.0-47) I am no longer able to run an application that
checks it's data directory for write access/path traversal when that
directory is an NFS share. This works on 4.4 and 3.13 kernels that I
tested with but fails on 4.15. I'm using NFSv3 and have seen the
behavior with both a synology NAS as the nfs-server as well as my xenial
desktop as the nfs-server.

To reproduce:
0.) Boot test machine with kernel 4.15.0-47
1.) set up a NFS export on another machine (nfs-server)
/etc/exports:
/srv/nfstest   192.168.100.100(rw,sync,no_subtree_check)

2.) mount the NFS share on the test machine and give a non-root user
ownership of the mount, in my case I have a user: aptly, with
home=/var/lib/aptly, and I mounted the NFS at /var/lib/aptly/test.
aptly:aptly owns /var/lib/aptly/test.

/etc/fstab:
192.168.100.101:/srv/nfstest/var/lib/aptly/test  nfs rw,mountvers=3


3.) attempt to call access.W_OK on the mount as the non-root user `strace 
./testaccess.py`
stderr:
...
access("/var/lib/aptly/test", W_OK) = -1 EACCES (Permission denied)
...
stdout:
('Writeable:', False)
('user r,e,s', (5062, 5062, 5062))
('group r,e,s', (5062, 5062, 5062))

st_mtime=1554858633, st_ctime=1554858633)

[Bug 1820063] Re: [Hyper-V] KVP daemon fails to start on first boot of disco VM

[Francis Ginther]

This fixed the problem that I'm seeing on disco with a 20190402 serial.
My test was to recreate the problem by removing /dev/vmbus/hv_kvp then
rebooting. This simple test showed that the service came up again in a
failed state with 'systemctl status hv-kvp-daemon.service'.

Then I installed this updated package, and redid the same experiment.
This time the service was running with no errors.

I dislike this change.

While ASLR is not particularly strong on 32 bit platforms, it is
significantly more useful when used with 64 bit platforms. Go itself may
be relatively safe from the common mistakes that make ASLR really useful
in C, but loading C libraries does happen.

Furthermore I'm not confident it will actually help. The problem appears
to be that a specific size was requested at a specific location and
MAP_FIXED prevents the kernel from finding another region where the
requested allocation could fit:

mmap2(0x7f90, 150536192, PROT_READ|PROT_WRITE, 
MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot
allocate memory)

Removing the MAP_FIXED would probably allow this allocation to continue,
albeit at a different location, and would also avoid the caveat given
in the mmap(2) manpage:


  Furthermore, this option is extremely hazardous (when
  used on its own), because it forcibly removes
  preexisting mappings, making it easy for a
  multithreaded process to corrupt its own address
  space.

[Bug 1817049] Re: Subiquity should install security updates before first login

[Marc Deslauriers]

Today, ubiquity has the "Download updates while installing Ubuntu"
option during installation, which will then be installed automatically
after the first reboot. This bug was filed to obtain a similar feature.

ukui-control-center set automatic login by dbus. when you sets the
automatic login and reboot, the value of AutomaticLogin is false in

[Bug 1824043] [NEW] ttf-mscorefonts-installer asks sudoer rights but dialog does not wait

A window proposes to finish the installation of ttf-mscorefonts-

the identification windows that comes for some upgrades (kernel etc.).

[Bug 1817049] Re: Subiquity should install security updates before first login

[Steve Langasek]

We discussed this on a Foundations internal call this afternoon, and
several counterarguments came up:

 - this is inconsistent with how other Ubuntu installers work today (e.g. 
ubiquity doesn't do this)
 - the point at which security updates can be installed is very late in the 
installation process, so installing updates before reboot is very likely to 
increase the time it takes to install a system
 - curtin already has to apt install the kernel, and should prefer the one from 
the security pocket if network updates are possible, so the 99% case for 
reboot-requiring security updates is already handled for subiquity installs 
without additional changes here
 - we don't have a clear idea of what's "expected" (do we want no updates? only 
security updates? all updates?) and we don't want to just punt the question to 
the user by making them answer this question as part of the install.

I think one thing it is reasonable to do is start the background
downloading of the security updates once the rootfs is configured
('systemctl start apt-daily.service').  Maybe we should also consider
special-casing apt-daily-upgrade.service on first boot so that it runs
immediately instead of waiting until 6am.  But I think the justification
for enforcing that security updates are applied specifically before
first login is weak; if there were security bugs so grave that we are
worried about the user launching an insecure browser (the example
given), we should equally be worried about this insecure browser being
shipped in the live images (both desktop and server).

Did you get any logs or apport crash reports when it died?

I've been running usbguard and usbguard-applet-qt since 2018-06-25 and
have really been happy with it. I've always intended to compare it against
usbauth but because usbguard has just worked flawlessly I never got around
to trying the alternatives.

[Bug 1820363] Re: NEC/Renesas PCI USB3 Cards (uPD720201) Host halt failed, -19

[Mike]

@Fabien

I confirm from 4.10 broken support and fighting for repairing USB 3.0
cards on other Bug thread. I tried to bitsect kernel 4.9a to 4.10a but
they are so different that it cannot be done by git automatically.
Somene who redesigned 4.10 PCI USB 3.0 mess should take care of it. The
hardware is ready to test.

I order You to use W201FW21.exe for updatng firmware to
upd720201/upd720202 or W200FW35.exe for updatng firmware to
upd720200/upd720200A. The integrated GUI all in one updater starting
with Fxx.exe cannot downgrade firmware at all. You will find them on
the net easily by the NEC firmware. The gods of linux flashrom package
didn't want to take care of upd720200a datasheet and PCI/PCIE host to
support FW flashing on linux.

[Bug 1823836] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From wil...@us.ibm.com 2019-04-09 20:09 EDT---
-EOPNOTSUPP is returned from ib_uverbs kernel module.

Call stack:
ib_uverbs_ex_create_rwq_ind_table()   >>   uverbs_request_finish()

I found iter.cur may not be correct at the time uverbs_request_finish()
is called.   iter.cur was been computed in uverbs_request_next() prior
to calling uverbs_request_finish().

Here is my kernel tracing showing the problem.

uverbs_request_next.isra.7: Befor iter->cur=e6061050 len=4
uverbs_request_next.isra.7: After iter->cur=ced0d1bc len=4

The second value of iter->cur not correct, this is not making much
sense,  is a cast is needed?

static int uverbs_request_next(struct uverbs_req_iter *iter, void *val,
size_t len)
{
if (iter->cur + len > iter->end)
return -ENOSPC;

if (copy_from_user(val, iter->cur, len))
return -EFAULT;

trace_printk("Befor iter->cur=%p len=%lu\n",iter->cur,len);

iter->cur += len;

trace_printk("After iter->cur=%p len=%lu\n",iter->cur,len);

return 0;
}

[Bug 1812527] Re: [bionic][regression] gnome-shell crashes with SIGSEGV in meta_window_actor_is_destroyed(self=NULL) called from _switchWorkspaceDone() [windowManager.js:1787]

[Alec Larsen]

This problem also affects me with Zoom. I am also using a Dell Precision
5520 with Intel HD Graphics, and disabling animations in Tweaks /
Appearance / Animations fixes the problem for me.

I arrived at this thread by Googling the last few frames in my coredump:

[Bug 1823410] Re: utils.py's url_downloadable doesn't support https

[Brian Murray]

** Description changed:

- In the interest of improving release upgrades for users of PPAs a check
- was added to ubuntu-release-upgrader to see if the release to which the
- system is being upgraded is provided by a sources list entry and if it
- is not that entry is disabled. This check uses the function
- url_downloadable which is provided by update-manager's utils.py. Come to
- find out the url_downloadable check only supports ftp and http, not
- https. This can cause a situation where upgrades to the next release of
- Ubuntu fail if the system's mirror of the Ubuntu archive is using https.
- This is mentioned here - https://bugs.launchpad.net/ubuntu/+source
- /ubuntu-release-upgrader/+bug/1807043/comments/10.
+ [Impact]
+ In the interest of improving release upgrades for users of PPAs a check was 
added to ubuntu-release-upgrader to see if the release to which the system is 
being upgraded is provided by a sources list entry and if it is not that entry 
is disabled. This check uses the function url_downloadable which is provided by 
update-manager's utils.py. Come to find out the url_downloadable check only 
supports ftp and http, not https. This can cause a situation where upgrades to 
the next release of Ubuntu fail if the system's mirror of the Ubuntu archive is 
using https. This is mentioned here - 
https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1807043/comments/10.
  
  While the bug manifests itself in ubuntu-release-upgrader it needs
  fixing in update-manager and will require a rebuild of ubuntu-release-
  upgrader which has a symlink to utils.py which is shipped in the dist-
  upgrader tarball.
+ 
+ [Test Case]
+ update-manager - only ubuntu-release-upgrader uses url_downloadable but I 
added a test to update-manager to ensure that https works, the test may be 
skipped though if the https test site is not available so keep an eye out for 
that.
+ 
+ ubuntu-release-upgrader
+ 1) On a xenial or bionic system edit your sources.list file so that you are 
using an https mirror of the archive.
+ 2) try to upgrade to the next release of ubuntu using 'do-release-upgrade'
+ 
+ With the version of ubuntu-release-upgrader in the archive you will not
+ be allowed to upgrade because ubuntu-minimal will not be found. With the
+ version in -proposed, accessed by using 'do-release-upgrade -p' you
+ should be able to upgrade to the next release of Ubuntu.
+ 
+ [Regression Potential]
+ There isn't much chance of a regression as we are just adding https to the 
list of schemes that we will test with urlopen.
