| * sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

| * sysfs: make directory dentries and inodes reclaimableTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes dentries and inodes for sysfs directories reclaimable. * sysfs_notify() is modified to walk sysfs_dirent tree instead of dentry tree. * sysfs_update_file() and sysfs_chmod_file() use sysfs_get_dentry() to grab the victim dentry. * sysfs_rename_dir() and sysfs_move_dir() grab all dentries using sysfs_get_dentry() on startup. * Dentries for all shadowed directories are pinned in memory to serve as lookup start point.

| * sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

| * sysfs: add sysfs_dirent->s_nameTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add s_name to sysfs_dirent. This is to further reduce dependency to the associated dentry. Name is copied for directories and symlinks but not for attributes. Where possible, name dereferences are converted to use sd->s_name. sysfs_symlink->link_name and sysfs_get_name() are unused now and removed. This change allows symlink to be implemented using sysfs_dirent tree proper, which is the last remaining dentry-dependent sysfs walk.

| * ida: implement idr based id allocatorTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement idr based id allocator. ida is used the same way idr is used but lacks id -> ptr translation and thus consumes much less memory. struct ida_bitmap is attached as leaf nodes to idr tree which is managed by the idr code. Each ida_bitmap is 128bytes long and contains slightly less than a thousand slots. ida is more aggressive with releasing extra resources acquired using ida_pre_get(). After every successful id allocation, ida frees one reserved idr_layer if possible. Reserved ida_bitmap is not freed automatically but only one ida_bitmap is reserved and it's almost always used right away. Under most circumstances, ida won't hold on to memory for too long which isn't actively used. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * DMI-based module autoloadingLennart Poettering2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch below adds DMI/SMBIOS based module autoloading to the Linux kernel. The idea is to load laptop drivers automatically (and other drivers which cannot be autoloaded otherwise), based on the DMI system identification information of the BIOS. Right now most distros manually try to load all available laptop drivers on bootup in the hope that at least one of them loads successfully. This patch does away with all that, and uses udev to automatically load matching drivers on the right machines. Basically the patch just exports the DMI information that has been parsed by the kernel anyway to userspace via a sysfs device /sys/class/dmi/id and makes sure that proper modalias attributes are available. Besides adding the "modalias" attribute it also adds attributes for a few other DMI fields which might be useful for writing udev rules. This patch is not an attempt to export the entire DMI/SMBIOS data to userspace. We already have "dmidecode" which parses the complete DMI info from userspace. The purpose of this patch is machine model identification and good udev integration. To take advantage of DMI based module autoloading, a driver should export one or more MODULE_ALIAS fields similar to these: MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*"); MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*"); These lines are specific to my msi-laptop.c driver. They are basically just a concatenation of a few carefully selected DMI fields with all potentially bad characters stripped. Besides laptop drivers, modules like "hdaps", the i2c modules and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS lines. Besides merely exporting the DMI data via sysfs the patch adds support for a few more DMI fields. Especially the CHASSIS fields are very useful to identify different laptop modules. The patch also adds working MODULE_ALIAS lines to my msi-laptop.c driver. I'd like to thank Kay Sievers for helping me to clean up this patch for posting it on lkml. Patch is against Linus' current GIT HEAD. Should probably apply to older kernels as well without modification.

When the address differs when setting it, the real device is put in promiscous mode twice, but never taken out again. Additionally it doesn't resync when the real device's address is changed and needlessly puts it in promiscous mode when the vlan device is still down. Fix by moving address handling to vlan_dev_open/vlan_dev_stop and properly deal with address changes in the device notifier. Also switch to dev_unicast_add (which needs the exact same handling). Since the set_mac_address handler is identical to the generic ethernet one with these changes, kill it and use ether_setup(). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

The old one had a race with recvmsg, that resulted in false positives and hence data loss. The old algorithm operated on all unix sockets in the system, so any additional locking would have meant performance problems for all users of these. The new algorithm instead only operates on "in flight" sockets, which are very rare, and the additional locking for these doesn't negatively impact the vast majority of users. In fact it's probable, that there weren't *any* heavy senders of sockets over sockets, otherwise the above race would have been discovered long ago. The patch works OK with the app that exposed the race with the old code. The garbage collection has also been verified to work in a few simple cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a last step of preventing DoS by creating lots of expectations, this patch introduces a global maximum and a sysctl to control it. The default is initialized to 4 * the expectation hash table size, which results in 1/64 of the default maxmimum of conntracks.

Use a hashtable for expectations to avoid incurring the search overhead for every new connection. The default hash size is 1/256 of the conntrack hash table size, this can be overriden using a module parameter. This patch only introduces the hash table for expectation lookups and keeps other users to reduce the noise, the following patches will get rid of it completely.

This patch removes the never used ability to use masks for the destination part of the expectation tuple and completely removes masks from helpers since the only reasonable choice is a full match on l3num, protonum and src.u.all.

Since the default hashsize to max. entries ratio sucks (1:16), this patch doesn't reduce the amount of memory used for the hash by default, but instead uses a better ratio of 1:8, which results in the same max. entries value. One thing worth noting is early_drop. It really should use LRU, so it now has to iterate over the entire chain to find the last unconfirmed entry. Since chains shouldn't be very long and the entire operation is very rare this shouldn't be a problem. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
