2009-03-30proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

Use proc_create() to make sure that ->proc_fops be setup before gluing PDE to main tree. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[NET]: Make /proc/net per network namespaceEric W. Biederman
This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

2007-07-18[IrDA]: Fix IrDA build failureSamuel Ortiz
When having built-in IrDA, we hit the following error: `irda_sysctl_unregister' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `irda_proc_unregister' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `irsock_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `irttp_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `iriap_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `irda_device_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `irlap_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o `irlmp_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o make[1]: *** [.tmp_vmlinux1] Error 1 make: *** [_all] Error 2 This is due to the irda_init fix recently added, where we call __exit routines from an __init one. It is a build failure that I didn't catch because it doesn't show up when building IrDA as a module. My apologies for that. The following patch fixes that failure and is against your net-2.6 tree. I hope it can make it to the merge window, and stable@kernel.org is CCed on this mail. Signed-off-by: Samuel Ortiz <samuel@sortiz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
