2006-02-07[PATCH] sys_hpux: fix strlen_user() raceKyle McMartin
Userspace can alter the string after the kernel has run strlen_user(). Also: the strlen_user() return value includes the \0, so fix that. Also: handle EFAULT from strlen_user(). It's unlikely anyone is using this code. Very, very unlikely. If I remember correctly, CONFIG_HPUX turns this code on, but one would actually need CONFIG_BINFMT_SOM to load a binary that could cause a problem, and BINFMT_SOM has had an #error in it for quite some time.

2006-02-07[PATCH] uml: initialize process FP registers properlyJeff Dike
We weren't making sure that we initialized the FP registers of new processes to sane values. This patch also moves some defines in the affected area closer to where they are used.

2006-02-07[PATCH] uml: block SIGWINCH in ptrace tester childJeff Dike
The process that UML uses to probe the host's ptrace capabilities can (rarely) receive a SIGWINCH, confusing the parent. This fixes that by blocking SIGWINCH.

2006-02-07[PATCH] uml: balance list_add and list_del in the network driverJeff Dike
The network driver added an interface to the "opened" list when it was configured, not when it was brought up, and removed it when it was taken down. A sequence of ifconfig up, ifconfig down, ... caused it to be removed multiple times from the list without being added in between, resulting in a crash. This patch moves the add to when the interface is brought up.

2006-02-07[PATCH] uml: close TUN/TAP file descriptorsJeff Dike
When UML opens a TUN/TAP device, the file descriptor could be copied into later, long-lived threads, holding the device open even after the interface is taken down, preventing it from being brought up again. This patch makes these descriptors close-on-exec so that they disappear from helper processes, and adds CLONE_FILES to a UML helper thread so that the descriptors are closed in the thread when they are closed elsewhere in UML.

2006-02-07[PATCH] uml: add debug switch for skas modeJeff Dike
It doesn't do anything but emit a warning, but there's a user population that's used to adding 'debug' to the UML command line in order to gdb it. With skas0 mode, that's not necessary, but these users need some indication that 'debug' doesn't do what they want.

2006-02-07[PATCH] x86_64: Fix the node cpumask of a cpu going downRavikiran G Thirumalai
Currently, x86_64 and ia64 arches do not clear the corresponding bits in the node's cpumask when a cpu goes down or cpu bring up is cancelled. This is buggy since there are pieces of common code where the cpumask is checked in the cpu down code path to decide on things (like in the slab down path). PPC does the right thing, but x86_64 and ia64 don't (This was the reason Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce on other arches). This patch fixes it for x86_64. I won't attempt ia64 as I cannot test it. Credit for spotting this should go to Alok. (akpm: this was applied, then reverted. But it's OK now because we now use for_each_cpu() in the right places).

2006-02-07[MIPS] TX49x7: Fix reporting of the CPU name and PCI clockSergei Shtylylov
I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips... Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937"); and some debug printk() were duplicating each other...

Fix a really old buglet in AMD Au1xx0 restart code: instead of modifying the whole CP0 Config.K0 field to 010b (meaning KSEG0 uncached) before flushing the caches and resetting a board, it only sets bit 1 of that reg. which is effectively a NOP since Config.K0 == 011b as the kernel sets it up (which is also its default value for Au1xx0).
