Hi, Tim, Well, at this point, hpssd is kind of a carry-over from pre-hpmud releases when we had two separate startup time daemons (hpiod and hpssd). I have plans to remove hpssd from the system, but as of right now, it is performing some functions that I cannot easily move to a non-daemon process. It is by design that the first user of HPLIP will start hpssd if it is not running. Currently, hpssd's main functions have to do with: 1. Routing events from hp:, hpfax:, and other event sources to one or more event sinks (hp-toolbox, etc) 2. Routing fax data from hpfax: to hp-sendfax 3. Saving a device's event buffer 4. I few other misc generic functions like caching device values that are expensive to retrieve My plan to replace hpssd involves: 1. For event routing, use dbus 2. For fax data routing, move the fax send code to hpfax: and then communicate with a UI using some IPC mechanism, perhaps dbus 3. For saving the event buffer and caching device values, I do not currently have a plan One idea I have is to implement a "system tray icon" that would replace the daemon-like hpssd process, but would allow the user to control its start/stop explicitly, and 1 process would run per-user. This would allow me to easily handle items 3 and 4. I am waiting on moving ahead on this because of my planned port to Qt4. Qt4 has a tray icon class that would make design/implementation of this easier. Thanks, Don On 10/31/07, Tim Waugh <tw...@re...> wrote: > > What is the purpose of hpssd?

What is the purpose of hpssd? It seems that some commands, such as hp-info, will start hpssd and leave it running. Is that intentional? Should that be running as the user who invoked (e.g.) hp-info, or is it meant to be system-wide? Thanks, Tim. */ |

Hi, I don't use samba at all, but I suppose it's only mistype.

Good analogy - device file permissions for ownership is separate from device file permissions for using the device file (ie: group and other). Only the device owner has the right to change device file permissions.

Yes, all the hplip i/o code is in io/hpmud. For usb all i/o goes through libusb/usbfs. All read/writes to any end-point require a claim_usb_interface(). Once the interface is claimed all i/o to that interface is exclusive (ie: 7/1/2). Parallel i/o is similar. All hpmud parallel i/o goes through ppdev/parport. Before any i/o can take place PPCLAIM will claim exclusive access to the port (ie: /dev/parport0).=20 -dave=20 |

Hello David, On Oct 23 21:31 Suffield, David wrote (shortened): > Changing OWNER="lp" to OWNER="root" is a valid change.

I am also no security expert. That's why I follow any advise from our security team. As far as I understand it, traditional security in Unix/Linux (i.e. without additional stuff like AppArmor or SELinux) is done by a separation by using different user accounts. Here changing the device file permissions is separated from using the device file (under the given permissions) by using different user accounts for the device file owner (the only user account - except "root" - which can change the permissions) and for those who should only use it. Therefore OWNER="johndoe", GROUP="lp", MODE="0666" would also do this separation (now only "johndoe" and "root" can change the permissions) but usually it is not desired that "johndoe" can change device file permissions so that I simply use the "default system owner" which is "root". In my HPLIP 2.7.10 packages on http://download.opensuse.org/repositories/home:/jsmeix/ I have OWNER="root", GROUP="lp", MODE="0666" Let's simply wait and see if there are any complaints because of it. Another example how the separation implements security: The cupsd runs under a differnt user than the filters and backends so that filters and backends cannot change internal settings (i.e. the config) of the cupsd. Again if cupsd would run as user "johndoe" and filters and backends would run as user "lp" the separation would exist. But unfortunately traditional Unix/Linux does not allow that a normal user "johndoe" can open ports below 1024 (but cupsd must open port 631) and/or that a normal user can switch automatically (i.e. without a password dialog) to user "lp" to run the filters and backends as user "lp". In particular because of the latter, cupsd must run all the time as root. > > For MODE="0666" the crucial question is whether or not it is > > possible that another user (e.g. someone who is logged in > > from remote) can somehow eavesdrop when a (confidental) > > document is printed or scanned. > > > > Is eavesdropping somehow possible with MODE="0666"? > > Given only one process can claim the USB interface for reading or > writing, and claiming the interface is arbitrated by the kernel, I would > say no other process could snoop the print job or scan job. Could you give me some more details what hpmud does to open the device file so that I can let our security team have a look at it or should they simply check all the files in io/hpmud/? > Setting the permissions to MODE="0666" is strictly the default for hplip > tar ball install. We have a lot of customers performing the tar ball > install so this makes it much easer from a customer support standpoint > with all the different distributions. I recommend not to sacrifice "reasonable security by default" for "make it easy for the customer" because in particular your unexperienced customers can only blindly trust you that your software doesn't do any harm or allow that harm can happen. You may have a look at http://en.wikipedia.org/wiki/Three_Laws_of_Robotics It depends on what you think is worth more: The reputation that HP is a company which can be trusted or blindly make everything easy for the user. If your software causes harm and a public discussion happens, it would not help you to say "root is required to install it". For example have a look at what Samsung did in their attempt to make everything easy for the user with their driver. I don't know how big the damage is for Samsung but at least they are now known as an example for insecure drivers from manufacturers - in contrast to real free-software drivers where at least more people have had a look before it hits unexperienced customers. By the way: It is such a pleasure that we can discuss such issues directly with the people at the manufacturer on a public accessible mailing list to find step by step the best possible solution - i.e. the right balance between "reasonable security by default" and "make it easy for the customer".

Given only one process can claim the USB interface for reading or writing, and claiming the interface is arbitrated by the kernel, I would say no other process could snoop the print job or scan job.

I tried to duplicate the problem and I do not think the problem is with aborting the print. It seems to abort fine (at least for now). However, the problem is with the printer doing its stuff (cleaning?) after the abort and after normal print also, when if I send another job to it, it either keeps blinking or just hangs up. I believe that the printer returns IDLE status when the new job is sent because I test for it when I close the (previous) job. I need to reset the computer and printer to recover.

Windows spooler will send printer ready data (pcl in this case) to the Linux server. Cups on Linux side will then send the raw data to the printer bypassing hplip. The only piece of hplip that will come into play here is the hp usb backend. You can change it to system's usb back end (assuming the printer is connected via usb) and try again. If that works, then you have a case against hplip. At the time you are setting up the queue, the transaction is between Windows spooler and Samba, hplip wouldn't be invoked. Hope this helps.

Subject: [HPLIP-Devel] Printing from windows to CUPS server with HPPhotosmart C3100 series driver Hello, I have linux (ubuntu) box with HP Photosmart C3100 and CUPS server. I tried printing from MS windows (Media Center Edition - it's like XP, I guess) via IPP (http://host/printers/printer). But it didn't work with "generic - MS Imagesetter" nor with "HP - HP photosmart 3100". Moreover, "add printer" dialog froze after selecting driver.

Hello, I have linux (ubuntu) box with HP Photosmart C3100 and CUPS server. I tried printing from MS windows (Media Center Edition - it's like XP, I guess) via IPP (http://host/printers/printer). But it didn't work with "generic - MS Imagesetter" nor with "HP - HP photosmart 3100". Moreover, "add printer" dialog froze after selecting driver. In cups' error_log I could see these messages (debug level) repeating every 2 seconds: D [18/Oct/2007:20:40:37 +0200] cupsdReadClient: 7 POST /printers/HPc3100 HTTP/1.1 D [18/Oct/2007:20:40:37 +0200] cupsdAuthorize: No authentication data provided. D [18/Oct/2007:20:40:37 +0200] Get-Printer-Attributes http://minerva:631/printers/HPc3100 D [18/Oct/2007:20:40:37 +0200] cupsdProcessIPPRequest: 7 status_code=0 (successful-ok) after stopping "Print spooler" in windows, "add printer" dialog unfroze and I could go on with adding printer. Printing from another cups client to this cups server (same printer) works fine, printing from same windows client to another printer on same cups server works fine as well! That's why I think it's a problem in hplip. distro: ubuntu gutsy gibbon (beta) printer: HP Photosmart C3110 Printer Driver: HP PhotoSmart C3100 Foomatic/hpijs (recommended) Device URI: hp:/usb/Photosmart_C3100_series?serial=CN6C6C52Q304P9 But I found similar problems with different photosmart printers, when googling for solution. workaround: *remove all relevant printers in windows client *reset print spooler *create new "proxy" printer in cups (set address http://localhost:631/printers/HPc3100), and driver generic - generate pdf *in windows add this "proxy" printer (with MS Imagesetter driver) |

For the upcomming openSUSE 11.0 I will use "resmgr" also for plain printers (to make device status available for the "console user") and fortunately we now have the USB device IDs so that it is possible to have it set up correctly out of the box. But I still wonder if perhaps mode 0666 is o.k. for HP USB printers and all-in-one devices if eavesdropping is not possible with MODE="0666". E.g. because for each device IO the hpmud library tries to open it only exclusively so that eiher an existing eavesdropper is noticed and hpmud would not open it, or after the exclusive open via hpmud no additional open by an eavesdropper is possible.

I do not understand why there is OWNER="lp" in 55-hpmud.rules. When the owner is lp, then any CUPS filter script or backend can change the permissions as it likes, for example via http://www.cups.org/str.php?L790 With the default MODE="0666" there is not much to change for a possible attacker but think about that the admin may have specified a more restrictive mode but forgot to also change the owner to root. To be more on the safe side, I would like to have OWNER="root", GROUP="lp", MODE="0666" by default for openSUSE. Is there any functionality which does no longer work out of the box if OWNER="root"? For MODE="0666" the crucial question is whether or not it is possible that another user (e.g. someone who is logged in from remote) can somehow eavesdrop when a (confidental) document is printed or scanned. Is eavesdropping somehow possible with MODE="0666"? > 17.

Currently this package contains only /usr/bin/hpijs and some documentation.

Would then the plain /usr/bin/hpijs work for his ZJStream printer? I.e. would the plain /usr/bin/hpijs autmatically find his plug-in and use it or is additional software needed and in case of the latter which additional software from HPLIP is needed? By the way: There is nothing about the new LJZjsMono device class at http://hplip.sourceforge.net/tech_docs/device_classes.html or about the new plug-in mechanism at http://hplip.sourceforge.net/tech_docs/hpijs.html Kind Regards Johannes Meixner -- SUSE LINUX Products GmbH, Maxfeldstrasse 5, 90409 Nuernberg, Germany AG Nuernberg, HRB 16746, GF: Markus Rex |

Attached is an update of the installation notes of hplip on Linux From Scratch/Beyond Linux From Scratch, this time for the 2.7.9 release. The notes presently in the Hplip documentation need to be replaced by this. Judging from some of the Help-cries I have read, this may be of some use. Keep up the good work! Niko Sauer |
