The 80c wire bit is bit 13, not 14. Bit 14 is always 1 if word93 is implemented. This increases the chance of incorrect wire detection especially because host side cable detection is often unreliable and we sometimes soley depend on drive side cable detection. Fix the test and add word93 validity check. Signed-off-by:

This patch updates the sata_promise driver to use new-style libata error handling for 20619 (TX4000) chips. sata_promise already uses new EH for the other chips it supports, so the patch is quite simple: * remove ->phy_reset and ->eng_timeout ops from pdc_pata_ops, and instead bind ->freeze, ->thaw, ->error_handler, and ->post_internal_cmd to existing new EH functions * drop ATA_FLAG_SRST from board_20619's flags * remove now unused pdc_pata_phy_reset() and pdc_eng_timeout() Tested on a TX4000 with both modern working disks and old/quirky disks. Also used a CD-RW drive to test reading and writing CDs. Signed-off-by:

Since the security checks are applied on each read and write of a sysctl file, just like they are applied when calling sys_sysctl, they are redundant on the standard VFS constructs. Since it is difficult to compute the security labels on the standard VFS constructs we just mark the sysctl inodes in proc private so selinux won't even bother with them. Signed-off-by:

Hmmm...turns out to not be quite enough, as the /proc/sys inodes aren't truly private to the fs, so we can run into them in a variety of security hooks beyond just the inode hooks, such as security_file_permission (when reading and writing them via the vfs helpers), security_sb_mount (when mounting other filesystems on directories in proc like binfmt_misc), and deeper within the security module itself (as in flush_unauthorized_files upon inheritance across execve). So I think we have to add an IS_PRIVATE() guard within SELinux, as below. Note however that the use of the private flag here could be confusing, as these inodes are _not_ private to the fs, are exposed to userspace, and security modules must implement the sysctl hook to get any access control over them.

I goofed and when reenabling the fine grained selinux labels for sysctls and forgot to add the "/sys" prefix before consulting the policy database. When computing the same path using proc_dir_entries we got the "/sys" for free as it was part of the tree, but it isn't true for clt_table trees. Signed-off-by:

With this change the sysctl inodes can be cached and nothing needs to be done when removing a sysctl table. For a cost of 2K code we will save about 4K of static tables (when we remove de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or about half that on a 32bit arch. The speed feels about the same, even though we can now cache the sysctl dentries :( We get the core advantage that we don't need to have a 1 to 1 mapping between ctl table entries and proc files. Making it possible to have /proc/sys vary depending on the namespace you are in. The currently merged namespaces don't have an issue here but the network namespace under /proc/sys/net needs to have different directories depending on which network adapters are visible. By simply being a cache different directories being visible depending on who you are is trivial to implement.

The current logic to walk through the list of sysctl table headers is slightly painful and implement in a way it cannot be used by code outside sysctl.c I am in the process of implementing a version of the sysctl proc support that instead of using the proc generic non-caching monster, just uses the existing sysctl data structure as backing store for building the dcache entries and for doing directory reads. To use the existing data structures however I need a way to get at them. [akpm@osdl.org: warning fix] Signed-off-by:

The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by:

parse_table has support for calling a strategy routine when descending into a directory. To date no one has used this functionality and the /proc/sys interface has no analog to it. So no one is using this functionality kill it and make the binary sysctl code easier to follow. Signed-off-by:

There are currently no users in the kernel for CTL_ANY and it only has effect on the binary interface which is practically unused. So this complicates sysctl lookups for no good reason so just remove it. Signed-off-by:

binfmt_misc has a mount point in the middle of the sysctl and that mount point is created as a proc_generic directory. Doing it that way gets in the way of cleaning up the sysctl proc support as it continues the existence of a horrible hack. So instead simply create the directory as an ordinary sysctl directory. At least that removes the magic special case. [akpm@osdl.org: warning fix] Signed-off-by:
