| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

* | x86: expand /proc/interrupts to include missing vectors, v2Joe Korty2007-10-171-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add missing IRQs and IRQ descriptions to /proc/interrupts. /proc/interrupts is most useful when it displays every IRQ vector in use by the system, not just those somebody thought would be interesting. This patch inserts the following vector displays to the i386 and x86_64 platforms, as appropriate: rescheduling interrupts TLB flush interrupts function call interrupts thermal event interrupts threshold interrupts spurious interrupts A threshold interrupt occurs when ECC memory correction is occuring at too high a frequency. Thresholds are used by the ECC hardware as occasional ECC failures are part of normal operation, but long sequences of ECC failures usually indicate a memory chip that is about to fail. Thermal event interrupts occur when a temperature threshold has been exceeded for some CPU chip. IIRC, a thermal interrupt is also generated when the temperature drops back to a normal level. A spurious interrupt is an interrupt that was raised then lowered by the device before it could be fully processed by the APIC. Hence the apic sees the interrupt but does not know what device it came from. For this case the APIC hardware will assume a vector of 0xff. Rescheduling, call, and TLB flush interrupts are sent from one CPU to another per the needs of the OS. Typically, their statistics would be used to discover if an interrupt flood of the given type has been occuring. AK: merged v2 and v4 which had some more tweaks AK: replace Local interrupts with Local timer interrupts AK: Fixed description of interrupt types.

* security: Convert LSM into a static interfaceJames Morris2007-10-172-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert LSM into a static interface, as the ability to unload a security module is not required by in-tree users and potentially complicates the overall security architecture. Needlessly exported LSM symbols have been unexported, to help reduce API abuse. Parameters for the capability and root_plug modules are now specified at boot. The SECURITY_FRAMEWORK_VERSION macro has also been removed. In a nutshell, there is no safe way to unload an LSM. The modular interface is thus unecessary and broken infrastructure. It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux.

* KEYS: Make request_key() and co fundamentally asynchronousDavid Howells2007-10-173-18/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make request_key() and co fundamentally asynchronous to make it easier for NFS to make use of them. There are now accessor functions that do asynchronous constructions, a wait function to wait for construction to complete, and a completion function for the key type to indicate completion of construction. Note that the construction queue is now gone. Instead, keys under construction are linked in to the appropriate keyring in advance, and that anyone encountering one must wait for it to be complete before they can use it. This is done automatically for userspace. The following auxiliary changes are also made: (1) Key type implementation stuff is split from linux/key.h into linux/key-type.h. (2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does not need to call key_instantiate_and_link() directly. (3) Adjust the debugging macros so that they're -Wformat checked even if they are disabled, and make it so they can be enabled simply by defining __KDEBUG to be consistent with other code of mine.

* local_t Documentation update 2Mathieu Desnoyers2007-10-171-0/+23
| | | | | | | | | | | | | | | | | Grant Grundler was asking for more detail about correct usage of local atomic operations and suggested adding the resulting summary to local_ops.txt. "Please add a bit more detail. If DaveM is correct (he normally is), then there must be limits on how the local_t can be used in the kernel process and interrupt contexts. I'd like those rules spelled out very clearly since it's easy to get wrong and tracking down such a bug is quite painful."

* CodingStyle: relax the 80-cole ruleAlan Cox2007-10-171-2/+5
| | | | | | | | | | | I would suggest this change to make CodingStyle properly reflect the style used by the kernel, rather than the current wording which is wishful thinking and misleading, and comes from the same school of thought that gets off on prescriptive grammar, latin and comp.std.c Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* Deprecate a.out ELF interpretersAndi Kleen2007-10-171-0/+11
| | | | | | | | | | | | | | | | | | | | | | | The Linux ELF loader is quite complicated and messy code (that could probably need a rewrite, but that's a different chapter). One particular messy part in it is the support for non ELF a.out ld.sos. This was originally added to make transition from a.out to ELF easier because an a.out ELF ld.so could be still build using an older a.out toolkit. But by now that should be fully obsolete and removing it would clean up binfmt_elf.c up a bit. I propose to deprecate this support and remove for 2.6.25. Drawback is that someone still runs their system with a.out ld.so they would need to update the ld.so when updating to a new kernel. This patch just adds an entry to the deprecation file and a printk warning users.
