From: <Urban.Widmark@enlight.net> The memset is because it was previously possible to send always the same CIFS fragment and use this to increase the data counters. When the data counter "exceeds" the amount of bytes expected this will return the buffer only partially initialised... With findfirst etc requests this should allow leaking kernel memory content. The other thing is that the data is only returned when data_tot and parm_tot both "exceed" the expected values. Previously it was possible to create a sequence of CIFS fragments that allowed exceeding the counters. The calling functions then would believe they received a number of bytes that does not fit into the allocated buffer. Signed-off-by:

When a system has a very large imbalance of overall memory size to ZONE_NORMAL (for example when large amounts of numa remap space are in use) page_writeback_init() may incorrectly set vm_dirty_ratio and dirty_background_ratio to zero; leading to divide by zero errors elsewhere. This patch bounds these at 1%. Signed-off-by:

Here is a patch for M32R SIO driver, which replaces deprecated MODULE_PARAM() with modern module_param(). * drivers/serial/m32r_sio.c: - Replace MODULE_PARAM() with module_param(). - Fix a typo: UARRT_RSA_BASE --> UART_RSA_BASE. Signed-off-by:

In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and TIOCCBRK with EINVAL. I've attached a patch that adds them to the compatibility list. Since all architectures have these ioctls ("m68knommu" inherits them from "m68k", "um" from its host) and use the same code, I think adding them to compat_ioctl.h is the correct choice (as opposed to adding them to arch/x86_64/ia32/ia32_ioctl.c).

There seems to have been a couple of thinkos in the NUMA init code, in particular in find_cpu_node(): * Property size returned is in bytes, not words * Off-by-one error in loop iteration Signed-off-by:

When the generic IRQ patch went in, it changed the behaviour of setup_irq (compared to the previous ppc64 version) in that we now don't call the handler's enable function if it has a startup function. The XICS interrupt controller has a startup function, and so we weren't getting any interrupts through the XICS because they never got enabled. This patch adds a call to xics_enable_irq to xics_startup and fixes the problem. Signed-off-by:

Recent changes to arch/ppc/boot/lib/Makefile cause CC arch/ppc/boot/lib/../../../../lib/zlib_inflate/infblock.o Assembler messages: FATAL: can't create arch/ppc/boot/lib/../../../../lib/zlib_inflate/infblock.o: No such file or directory when building a ppc kernel using O=$(output_dir) with CONFIG_ZLIB_INFLATE=n, because the $(output_dir)/lib/zlib_inflate directory doesn't get created. This patch, which makes arch/ppc/boot/lib/Makefile create the directory if needed, is one fix for the problem. Signed-off-by:Roland Dreier <roland@topspin.com> Signed-off-by:

Instead, tty_io.c will always copy user space data to kernel space, leaving the drivers to worry only about normal kernel buffers. No more "from_user" flag, and having the user copy in each driver. This cleans up the code and also fixes a number of locking bugs.

I forgot to add 'const volatile' to the I/O read/write functions in the last patch, and also forgot to update the _relaxed variants. This patch fixes that by adding 'const volatile' to the sn2 specific read/write routines as well as the ia64 machine vector wrappers. Signed-off-by:

This is a big patch mostly because I trimmed shub_mmr.h down from 17M to 11k or so. It fixes a number of things sparse discovered and removes some dead code, fixes up some prototypes, etc. Of note: o sn_proc_fs.c was directly dereferencing user pointers, fixed o sn_hwperf.c was missing an include and was using asm-ia64 directly o the I/O routines were all missing proper sparse annotations o dead code in prominfo_proc.c has been removed o fix generic build by putting numionodes into asm/sn/io.h With this patch applied, the check build is pretty clean. The sn_console bit depends on some of the other changes, so it's included here. Signed-off-by:

Looks like we were casting a value into a union and sparse doesn't like that. Why not just assign it directly to the appropriate field? Signed-off-by:

Some have noticed that the overlapping sched domains code doesn't quite work as intended (it results in disjoint domains on some machines), and that a top level, machine spanning domain is needed. This patch from John Hawkes adds it to the ia64 code. This allows processes to run on all CPUs in large systems, though balancing is limited. It should go to Linus soon now otherwise large systems will only have ~16p (depending on topology) usable by the scheduler. I sanity checked it on a small system after rediffing John's original, and he's done some testing on very large systems. Nick, can you buy off on the sched.c change? Alternatively, do you want to send that fix separately John? Nick did indeed ACK this change, but it isn't dependent on this ia64 specific part ... so it's going to be submitted separately.
