* [PATCH] N32 sigset and __COMPAT_ENDIAN_SWAP__akpm@osdl.org2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm testing glibc on MIPS64, little-endian, N32, O32 and N64 multilibs. Among the NPTL test failures seen are some arising from sigsuspend problems for N32: it blocks the wrong signals, so SIGCANCEL (SIGRTMIN) is blocked despite glibc's carefully excluding it from sets of signals to block. Specifically, testing suggests it blocks signal N^32 instead of signal N, so (in the example tested) blocking SIGUSR1 (17) blocks signal 49 instead. glibc's sigset_t uses an array of unsigned long, as does the kernel. In both cases, signal N+1 is represented as (1UL << (N % (8 * sizeof (unsigned long)))) in word number (N / (8 * sizeof (unsigned long))). Thus the N32 glibc uses an array of 32-bit words and the N64 kernel uses an array of 64-bit words. For little-endian, the layout is the same, with signals 1-32 in the first 4 bytes, signals 33-64 in the second, etc.; for big-endian, userspace has that layout while in the kernel each 8 bytes have the two halves swapped from the userspace layout. The N32 sigsuspend syscall uses sigset_from_compat to convert the userspace sigset to kernel format. If __COMPAT_ENDIAN_SWAP__ is *not* set, this uses logic of the form set->sig[0] = compat->sig[0] | (((long)compat->sig[1]) << 32 ) to convert the userspace sigset to a kernel one. This looks correct to me for both big and little endian, given that in userspace compat->sig[1] will represent signals 33-64, and so will the high 32 bits of set->sig[0] in the kernel. If however __COMPAT_ENDIAN_SWAP__ *is* set, as it is for __MIPSEL__, it uses set->sig[0] = compat->sig[1] | (((long)compat->sig[0]) << 32 ); which seems incorrect for both big and little endian, and would explain the observed symptoms. This code is the only use of __COMPAT_ENDIAN_SWAP__, so if incorrect then that macro serves no purpose, in which case something like the following patch would seem appropriate to remove it.

* [PATCH] vgacon: make VGA_MAP_MEM take size, remove extra useBjorn Helgaas2006-06-22
| | | | | | | | | | | | | | | | | | | | | VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense to do this to vga_vram_base, because we're going to access memory between vga_vram_base and vga_vram_end. But it doesn't really make sense to map starting at vga_vram_end, because we aren't going to access memory starting there. On ia64, which always has to be different, ioremapping vga_vram_end gives you something completely incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being nonsense. As a bonus, we often know the size up front, so we can use ioremap() correctly, rather than giving it a zero size. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: "Antonino A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kern_addr_valid is currently only being used in kmem_ptr_validate which is making some vague attempt at verfying the validity of an address. Only IA-64, PARISC and x86-64 actually make some actual effort to verify the validity of the pointer. Most architecture definitions of kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM on i386 and MIPS even as 0; the 0-definition will result in kmem_ptr_validate always failing which in turn will cause d_validate to always fail. d_validate's only two users are smbfs and ncpfs, so the 0 definition ended breaking those ...
