Can't we not raise this call if we have ENODEV? We are quickly going to be ignoring every network facing domain from executing sys_module. I am thinking of just adding dontaudit domain self:capability sys_module; [mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.

[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update. any program that opens a socket with a protocol that isn't loaded yet is going to trigger a modprobe. I'm not sure what you expect the kernel to do here. The difference is whether or not the kernel_t is getting the modprobe versus the individual type. Theoretically the kernel would only load kernel modules that it owns whereas allow a process to execute sys_module allows it to modify the kernel with its content. I don't know how the contexts are passed around when networking does its request_module calls. Maybe something can be done there to force it to be kernel_t. Eric ? This is due to commit 8909c9? If you add a netdev-* alias for the relevant modules, then it should only require CAP_NET_ADMIN here and not CAP_SYS_MODULE. This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
