Remove the optimization that validate server is only called once per LCU. If a device is set online we only know that we already know the LCU. But if the pathgroup was lost in between we have to do a validate server again to activate some features. Since we have no indication when a pathgroup gets lost we have to do a validate server every time a device is set online. Signed-off-by:

The vmlinux file for s390 contains a currently unused entry point, which is specified in two different locations: the linker script and the makefile. As it happens both definitions are different and the linker file is broken (_start does not exist) and the makefile specifies an entry point which makes no sense (the SALIPL loader entry point). So lets get rid of one definition (the makefile) and use the entry point of all other ipl methods (0x10000 -> startup) to be consistent. Signed-off-by:

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel) enabled. However, kdump only enables one CPU in the new environment, thus causing tg3 to abort MSI-X setup. When the driver attempts to enable INTA or MSI interrupt modes on a kdump kernel, interrupt delivery fails. This patch attempts to workaround the problem by forcing the driver to enable a single MSI-X interrupt. In such a configuration, the device's multivector interrupt mode must be disabled.

Add missing smp_rmb() primitives to the keyring search code. When keyring payloads are appended to without replacement (thus using up spare slots in the key pointer array), an smp_wmb() is issued between the pointer assignment and the increment of the key count (nkeys). There should be corresponding read barriers between the read of nkeys and dereferences of keys[n] when n is dependent on the value of nkeys. Signed-off-by:

Linus Torvalds authored
Jüri Aedla reported that the /proc/<pid>/mem handling really isn't very robust, and it also doesn't match the permission checking of any of the other related files. This changes it to do the permission checks at open time, and instead of tracking the process, it tracks the VM at the time of the open. That simplifies the code a lot, but does mean that if you hold the file descriptor open over an execve(), you'll continue to read from the _old_ VM. That is different from our previous behavior, but much simpler. If somebody actually finds a load where this matters, we'll need to revert this commit. I suspect that nobody will ever notice - because the process mapping addresses will also have changed as part of the execve. So you cannot actually usefully access the fd across a VM change simply because all the offsets for IO would have changed too. Reported-by:

In that case the error handling (len <= 0) will be bypassed since "len" is unsigned, and the loop continues with (p += len) being wrapped.
