Since then another 18 months have gone by ... Mostly trivial stuff for this. The only tricky part was realizing that the new handler_*_irq() paths do not use desc->chip->end(irq). Not a problem for the edge case as the ia64 iosapic routine for that was nop(). But the "level" case handled interrupt migration there. Just use a slightly modified version of the "end" routine as "unmask" for the level triggered case. Signed-off-by: Tony Luck <tony.luck@intel.com>

A missing call could introduce problems on some architectures. This patch incorporates the access_ok() check into compat_alloc_user_space() and also adds a sanity check on the length. The existing compat_alloc_user_space() implementations are renamed arch_compat_alloc_user_space() and are used as part of the implementation of the new global function. This patch assumes NULL will cause __get_user()/__put_user() to either fail or access userspace on all architectures. This should be followed by checking the return value of compat_access_user_space() for NULL in the callers, at which time the access_ok() in the callers can also be removed.

This was not noticed because in most circumstances it simply resulted in using the slow path because the siglock was apparently not available (under old spinlock rules). Problems occur when the ticket spinlock has value 0x0 (when first initialised, or when it wraps around). At this point the fsys.S code acquires the lock (changing the 0x0 to 0x1. If another process attempts to get the lock at this point, it will change the value from 0x1 to 0x2 (using new ticket lock rules). Then the fsys.S code will free the lock using old spinlock rules by writing 0x0 to it. From here a variety of bad things can happen. Signed-off-by: Tony Luck <tony.luck@intel.com>

This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.

So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1.

Paraphrased from the 1989 BSD patch by David Borman @ cray.com: These are the changes needed for the kernel to support LINEMODE in the server. There is a new bit in the termios local flag word, EXTPROC. When this bit is set, several aspects of the terminal driver are disabled. Input line editing, character echo, and mapping of signals are all disabled. This allows the telnetd to turn off these functions when in linemode, but still keep track of what state the user wants the terminal to be in. New ioctl: TIOCSIG Generate a signal to processes in the current process group of the pty. There is a new mode for packet driver, the TIOCPKT_IOCTL bit. When packet mode is turned on in the pty, and the EXTPROC bit is set, then whenever the state of the pty is changed, the next read on the master side of the pty will have the TIOCPKT_IOCTL bit set. This allows the process on the server side of the pty to know when the state of the terminal has changed; it can then issue the appropriate ioctl to retrieve the new state. Since the original BSD patches accompanied the source code for telnet I've left that reference here, but obviously the feature is useful for any remote terminal protocol, including ssh. The corresponding feature has existed in the BSD tty driver since 1989.
